The invention relates to engineering machines, made on the chassis of military tracked vehicles (UGM), in particular a tank, and can be used for lifting and moving loads, displacements and plan of soils, paving the column ways. and maintenance of military roads, breaching in the rubble, the non-explosive obstacles and areas of destruction in the conditions of warfare, as well as in emergency situations.

Known for engineering vehicles (excavator), equipped with devices for excavation and movement of soil, see the description of the utility model patent No. 33134, CL 7 E 02 F 3/00 ([1]), or kN. Berkman I.L., Ranjeev AV, Rasak Shovel construction excavators, M., "Higher school", 1986, ([2]), p.8-11; 5, 9. To improve mobility for non-cohesive soils or capacity excavators mounted on tracked chassis, and to improve mobility, in particular for applications in the construction, excavators mounted on a wheeled chassis. While both types of excavators can work with equipment designed for excavation direct or reverse shovel. For excavators developed universal equipment, the elements of which, depending on the installation, may be converted with the formation of both direct and reverse shovels, see [2], str-129, RES (a, b), and the e can be equipped with other construction or special working tools is (d).

Buckets (or other tools) such excavators are mounted on the boom, performed in the form of a pointing device consisting of one or two sections and a handle, which, directly mounted bucket or other tool.

To empower excavators at work on heavy soils excavator can be equipped with tooth Ripper, see, for example, Russian patent 2059764, CL E 02 F 5/32 ([3]), which can be used as a working tool for preliminary destruction of earth moved, for example frozen, and together with excavation bucket, forming a gripping-induced organ, see [2], str-177, is to capture and handling, the size of which does not allow to take place in excavational the bucket. In this gripping-induced body has the ability to capture, for example, beams, sleepers and theprimary arranged horizontally relative to the ground or with a slight slope toward her. The excavator excavation bucket and tooth cultivator provided with each individual actuator with an actuating cylinder, providing mobility and other working tool relative to each other.

For use in combat or emergency situations, such as with radiation pollution is m, such machines are unsuitable because of the lack of protection from weapons and narrow fields of application, for example the inability to use when lifting and moving of goods suitable for slinging.

It should be noted that there are armored, highly specialized machines, such as Emergency rescue machine according to Russian patent No. 2137701, CL In 66 23/36 ([4]), or the Engineering obstacle clearing vehicle" according to the Russian patent No. 2072088, CL 6 F 41 H 13/00 ([5]), capable of capturing long things. However, it is the narrow focus of such machines and the lack of job opportunities on the movement of soil are factors constraining their use.

Also known German engineering, armoured vehicle, "Pionierpanzer 3", made on the chassis of the tank Leopard 2", see, for example, the magazine "Soldat und Technik", August 2004, p.30-33, ([6]), is suitable for use in combat or emergency situations, due to the availability of armour that protects the crew from destruction weapons, hull.

The application on this machine working body in the form of a boom arm (similar design with the considered source [2]), consisting of two sections and a handle, which is installed as a working tool excavation bucket, it is not possible to apply such a machine in cramped conditions is, because of the boom arm needs extended in the vertical plane of the free zone in front of the body.

The latter are not adopted for the prototype of the most essential features of American self-propelled units (military tracked engineering vehicles) for breaching anti-tank obstacles - "Grizzly", see magazine "Foreign military review", No. 8, 2002, tab between pages 32 and 33, ([7]). As the chassis of this machine used armored chassis tanks "Abrams". Instead of a tower on a tank chassis mounted armoured superstructure, in which is located the crew. Among the engineering equipment of this machine is installed telescopic boom type with box-shaped cross-section in the shape of an isosceles triangle, which ends as a working tool pivotally mounted excavation bucket driven by a hydraulic cylinder that provides the ability to perform excavation work forward and backward shovel. The arrow is made with two fixed and retractable partition and installed along the flanges on the support-rotating device installed in a cylindrical superstructure made in the fore part of the body and placed in front of a cabin crew. It should be noted that the triangular box-shaped cross-section telescopic shall truly overhead angle is quite rational for the perception of vertical loads, typical when working excavation bucket, providing the minimum weight of the boom. Telescopic execution of the boom allows for dredging using, on the one hand, the almost complete spatial area in front of the body of the machine, on the other hand, allowing operation in tight to manipulate solid angle space in front of the body chassis.

However, engineering UGM "Grizzly" is not fully used telescopic boom with excavation bucket.

So, more fully such opportunities are used excavator-scheduler, produced by JSC Motovilikhinskiye Zavody", see attached leaflet for excavator scheduler EA-43212, ([8]), or kN. "Excavator-scheduler EA 43212 and its modifications. Manual ZTM 220-00.00.000 ER", JSC Motovilikhinskiye Zavody", 2001 ([9]), the extraction of which is also attached. Excavator-scheduler contains a telescopic boom with the main working body - excavation bucket (instead which can be used interchangeable, working bodies, such as planning the bucket or blade), providing not less than four working motions equipment: tilting of the boom in a vertical plane, rotating boom with bucket relative to the longitudinal axis, rotation of the bucket in a vertical plane relative to the boom is the extension of the boom. Structurally, the possibility of execution of the said movement is provided as follows. The inclination of the boom is provided by hydraulic cylinders, turning the portal arrows in the hinges fixed on the rotary platform. The extension of the boom is carried out by moving the sliding section of the boom of the excavator relative to the non-rising section, which hereinafter will be referred to as the reference section. Housing both the boom sections have a box-shaped section

Moves drawer by rotating the rollers, fixed to the body support section through the bearings. To move use extension mechanism (teleskopowe), located inside the pull-out section of the boom and is made in the form of a long stroke cylinder, connected on one side with a support section, the other side with eyelets pull-out section. The supporting section is fixed in the axial direction in the upper cylindrical part of the portal (the cylinder portal) arrows, and is provided rotatably by a rotation mechanism on the bearings relative to the Central axis of the cylinder portal. From falling out of the cylinder portal reference section is retained by the engagement of the end surfaces of the portal and reference sections, forming a heel slip. The rotation mechanism allows you to provide the rotation of the boom and associated excavating bucket (or other earth-moving equipment) at any position relative to the horizon, you need to work, which allows for planning, providing the specified angles dumps and slopes, for example, in road construction. Such translation excavating bucket from one working position to another is always in the off position excavating bucket, in the absence of axial load on the thrust bearings portal arrows, because in the working position has a high level of friction in the thrust bearing slide because of the actions directed along the arm part on the workload. To overcome the sliding friction in the presence of axial load in the device would require, first, a much more powerful actuator for effecting rotation and, secondly, it would increase the size (and mass) of the structure to the exclusion of breakdowns excavating equipment, including a rotation mechanism.

Excavation bucket used as a working tool excavator scheduler EA 43212 (or other working tool from the number shown in the source [8]) is set by sliding the sections are hinged and provided with a drive from short travel hydraulic cylinder, enabling rotation of the bucket to the boom or the turning away from the boom.

Returning to engineering machine prototype it should be noted the extent of projection of the cylindrical superstructure and the porn-turning device as a whole, which affects its protection against kinetic weapons, the lack of strelba equipment rotation mechanism, enabling rotation of the bucket or the entire telescopic boom relative to the longitudinal axis as without load and under load, which limits the possibility of using excavating equipment and is the disadvantage of the prototype. In addition, the possibility of such engineering machinery limited use for disassembly blockages and barriers in comparison with the excavator, equipment which contains additional tool, for example, the tooth cultivator, mounted with a possibility of formation of a gripping-tick of the working body. At the same time the direct transfer of known technical solutions for the installation of a tooth-Ripper from boom manipulator (see [3], str-177) in a telescopic boom is not possible due to the substantially smaller transverse dimensions of the drawers in comparison with a handle boom manipulator, limiting the possibilities for accommodation in drawers as Executive bodies and actuators to them.

For engineering machines, it is also advisable to allow rotation of the boom rotation mechanism in the presence of operating loads acting along the boom. When this form of the cross section of the arrows n what should be triangular (under condition of providing a similar level of ravnopravnosti cross-section of the boom at any possible application of the transverse force on the boom when operating the boom system). The best of these positions can be round or square (box-shaped) cross-sectional shape.

Thus, the disadvantages of military tracked engineering vehicles of the prototype are limited in functionality, the boom system and the limited host security turntable from the means of destruction.

The present invention is the development of military tracked engineering vehicles with enhanced functionality works the boom system and increased protection of a turntable from the means of destruction.

The technical result achieved by the invention is:

- increase the reflectivity of the armored corps to the means of destruction due to the proposed implementation of the shaping surface of the body of a turntable;

- a decrease in the required power of the rotation mechanism to rotate the boom in terms of work loads acting along the arrows, by reducing friction in the thrust bearing of the portal;

- to provide opportunities for education on the telescopic boom pick-tick of the working body through the installation of a tooth-Ripper on pull-out section with the lever mechanism in its drive placed in the dimensions specified partition;

- is obespechenie the possibility of using the excavator boom as a crane.

The problem is solved in that in the engineering tracked the car on the chassis base of the tank, comprising a housing mounted on the casing of the armoured cabin for the accommodation of the crew and of machinery, rotation device with a load-carrying platform and a hydraulic drive its rotation, mounted on the platform portal, two-section telescopic boom box-like form, comprising a control section and a sliding section, provided with a hydraulic cylinder teleskopowe and excavation bucket with hydraulic cylinder actuator according to the invention the rotation device is installed in the forward part of the chassis side cuttings and placed in an armored housing, console mounted on the wheelhouse and made in the form of low-profile direct cylinder with a bottom in the form of a spherical segment, provided by cutting the opening for the accommodation of actuator rotation bearing platform and the upper part of the support portal is made cylindrical and provided with a rotation mechanism of the arrows, with pull-out section of the boom is made jib on the end of the protruding part of which is placed lugs with the axis, on which is mounted excavation bucket and tooth-loosening placed under excavation bucket with the possibility of providing separate or joint operation by establishing a grapple-Kleschev the working body for use, for example, when the rubble and barricades, with wall pull-out section located on the opposite side of the jib, additionally equipped with a lifting hook suspension for slinging loads, and side walls made brackets, lugs are fixed two short-stroke cylinder associated with the tooth-Ripper via a lever mechanism with the formation of actuator rotation and fixation of the tooth-Ripper in a predetermined range of angles, and the side walls of the stationary section of the boom by sliding the sections are shaped cutouts to accommodate cylinders of the drive rotation of the tooth-Ripper when sending arrows from the working position and transport position.

The best result is achieved if:

- reference section of the boom is installed in the portal with the possibility of rotation of the boom rotation mechanism in terms of its axial loading when working excavation bucket or grapple-tick working body;

- at the lower end of the retractable section of the arrows on the outside of the walls of the installed lining with the ability to limit the deflection of the boom (the vertical displacements of the drawer relative to the reference) when the boom system with minimum boom, and the lining is made from a material with a low coefficient of friction, e.g. the bronze, or of high-strength material, for example steel, with anti-friction coating, for example disulfit-molybdenum on the surface of the lining;

- at the base of the support sections are made circular path, and in a cavity of a support portal running commercials with the possibility of rolling along a circular track in the wall of the portal is open for installation of the rollers, closed firmly fixed on the walls of the support portal covers, these covers are provided with pins, and rollers mounted on the axles through the bearings or roller bearings.

Analysis of the distinctive features of engineering tracked vehicle chassis base of the tank showed that:

- installation of a turntable in the forward part of the chassis on the side of the cutting and pinning his console in the wheelhouse increases visibility for the operator and improves the conditions of the loaded control equipment;

- installation of a turntable in an armored housing made in the form of a low profile direct cylinder with a bottom in the form of a spherical segment, increases protection from weapons;

- performance by cutting openings in the walls of the deckhouse and hull of a turntable with the internal placement of actuator rotation bearing platform provides a high level of protection of the drive means of destruction;

- follow the top of the portal in the form of a cylinder allows you to embed into the portal mechanism of the rotation of the boom, and the installation of a rotation mechanism of the boom extends the functionality on the application of the boom system;

- implementation of the jib on the end of the extendable section of the jib allows you to perform at the end of the protruding part of the developed lugs under axis to install the lever mechanisms and excavating bucket with tooth-Ripper with placing under excavation bucket, thus ensuring the possibility of separate work excavating bucket and tooth-Ripper or their joint work through the formation of small-sized pick-tick of the working body, used, for example, when the rubble and barricades;

- consolidation in the eyes of the brackets on the side walls of the extendable sections are short-stroke hydraulic cylinders associated with the tooth-Ripper via a lever mechanism is the formation of actuator rotation and fixation of the tooth cultivator in a predetermined range of angles, ensuring the development of the necessary work effort of capture;

- equip pull-out sections lifting hook suspension for slinging loads up on the wall pull-out section on the opposite side of the jib allows the use of engineering crawler machine as a crane;

- run in the side walls of the base section of the boom from sliding sclerogenic cut provides acceptable dimensions engineering caterpillar machine longitudinal dimensions by reducing the transport length of the boom by placing the hydraulic cylinders of the drive rotation of the tooth-Ripper in the above-mentioned the notches when the transfer boom of the working position and transport position;

- installation of supporting the sections in the portal with the possibility of rotation of the boom rotation mechanism without load and under axial loading when working excavation bucket or grapple-tick working body aimed at improving the efficiency of disassembly engineering machine obstacles in the form of rubble, destroyed buildings, etc. and reduce the required capacity in the rotation mechanism, the reduction of friction and smoovah processes in the portal and the base section of the boom. The constructive implementation of this idea is provided by the fact that at the base of the support sections are made circular path, and in the cavity of the portal running commercials with the possibility of rolling along a circular track in the wall of the portal is open for installation of the rollers, closed firmly fixed on the walls of the portal covers, these covers are provided with pins, and rollers mounted on the axles through the bearings or roller bearings, and execution in the wall of the cylindrical support portal hatches with covers and fastening the bearings through the trunnion on the covers of hatches allows you to enable the Assembly of an improved rotation mechanism;

- set at the lower end of the extendable sections on the outer side walls decl the dock is education limiters of boom deflection at the departure of her, close to the minimum.

- performance pads from a material with a low coefficient of friction, for example of bronze, has a low power loss on the interaction of the plates when moving the retractable section of the boom relative to the support; an equivalent solution is achieved by the implementation of plates of high-strength material such as steel with anti-friction coating, for example disulfit-molybdenum on the surface of the plates.

Engineering UGM, see figures 1 and 2, performed at baseline (taken as the base for family UGM) tank chassis 1, comprising a housing 2, equipped with an armored cabin 3, installed on the hull instead of a tank turret. In front of the cuttings placed Luke 4 mechanics of the driver, as well as hatches 5-7 other members of the crew, in the middle part of the housing 2 placed the engine room 8. VGM equipped with bulldozer 9 and loaded equipment 10, mounted to rotate on the rotating device 11. Supporting the rotary device 11 includes a carrier platform 12 and the rotary support 13 mounted in the housing 14, see also figure 3 and 4, made out the form of armour low profile cylinder (cylindrical ring) "a", smoothly transitioning into armor plate "b". The bottom b of the casing 14 to better address (reletively) kinetic power tools made in the form of a spherical segment. Case 14 a cantilever on the deckhouse, the internal cavity of the housing 14 are connected to the internal space of the cutting opening, in which oterom installed the drive rotation bearing platform, including the hydraulic motor 15 and the gear 16. This embodiment of the housing provides protection for the pivot 13 and the devices 15 and 16 from the effects of kinetic weapons.

The platform 12, see also figure 5, fitted with brackets 17 to pivotally secure portal 18. The upper part of the "g" portal 18 is made in the form of a hollow cylinder. The lower part of the portal 18 provided with brackets 19, the associated axis 20 with brackets 17 of the platform, forming the hinge and brackets 21, pivotally connected with the hydraulic cylinders 22, serving to tilt the boom 23 in the vertical plane by changing the inclination of the portal.

Arrow 23 telescopic, made of two sections, containing the anchor section 24 installed in the portal 18, and a pull-out section 25 installed inside (cavity) of the support section 24 with the possibility of reciprocating movement of the rollers 26 linear guides 27, see Fig.6. Both sections are made of box-shape with a rectangular cross-section.

Turn in the portal 18 support section 24 about its longitudinal axis is in a cylindrical slide bearing "d" and "e", see Fig.7, with the help of two mechanisms 28 rotation driven by a motor 29 mounted on the portal 18 and cooperating with the toothed wheel 30 connected with the supporting section 24.

On the outer end of the retractable seconds the AI 25 arrows made jib 31, see also Fig, at the end of the protruding part which is made eyes with the axis 32, which is pivotally mounted excavation bucket 33, and a tooth-loosening 34 located under excavation bucket. The rotation of the bucket 33 with respect to the axis 32 (rotation of the bucket in the plane of the arrows 23) is short travel hydraulic cylinder 35 mounted in the cavity pull-out section 25 through three lever mechanism 36. The rotation of the tooth-Ripper 34 with respect to the axis 32 (rotation of the tooth-rake arms 34 relative to the bucket 33) is carried out in two short travel hydraulic rams 37, figure 9, mounted on the side walls "W" along the pull-out section 25 of the housing which is mounted on the axis 38 in the eyes of the brackets 39 which are welded to the wall "W". The cylinders 37 are connected via a lever mechanism 40 with tooth-Ripper 34, effecting, when the flow of the operating fluid in the cylinder cavity, the rotation of the tooth-Ripper. The ratio of the shoulders at arm 41 mechanism 40 is selected so that when a short stroke hydraulic cylinder 37, the rotation of the tooth-Ripper is specified, necessary for the operation range of angles, roughly corresponding to the rotation angle range excavating bucket 33.

The use of independent drive (independent hydraulic cylinders 35 and 37) allows you to adjust the distance between the EC is cavacini bucket 33 and the tooth-Ripper 34, providing the possibility of their separate work or collaborate with the formation of capture-tick of the working body for use, for example, when the rubble and barricades. Because the arrow 23 in transport (Hiking) the provision of engineering and tracked vehicles should not significantly increase the longitudinal dimension of the machine, pull-out section 25 should probably go in the support section 24. To this did not prevent the installation of tooth cultivator and his drive in the side and bottom walls of the support section 24 is made of curly cut "and" to accommodate the mentioned brackets 39 and cylinders 37 of the drive tooth-rake arms 34, which helped reduce the overall length of the boom 23 in the transport position.

The presence of curly cut "and" in the reference section 24 of the boom led to the asymmetric location of the supports 27. So bearing (27) "K" and "l" on the upper side of the supporting section 24 was posted on a greater distance than support "m" and "n" on the bottom side of the support section. However, as will be shown below when describing the work of the engineering UGM, such a decrease, in General, did not impair the efficiency of the boom system.

On the pull-out section 25 of the boom wall, which is located on the opposite side of the jib (the upper side), equipped with a bracket 42 on which is mounted easily removable gruzozahvatnye the hook pendant 43 for slinging loads, see also figure 10. Thanks to this boom lifting equipment engineering UGM can be used as a crane equipment, additionally expanding operational capabilities.

The above mentioned tooth-loosening 34 can be used as an independent working tool, for example for loosening frozen ground after installation of the hydraulic cylinders 37 in the operating position. This symmetrical arrangement of the hydraulic cylinders 37 relative to the boom eliminates the possibility of unbalanced loading during operation.

Moving the pull-out section 25 of the boom is long stroke hydraulic cylinder 44 (hydraulic cylinder teleskopowe)connected to one end of the articulated suspension 45 installed in the drawer, the other end to the swivel bracket 46 fixed inside the supporting section in the beginning. To ensure the smooth movement of the sliding section 25 of the roller 26 of the supports 27, between the rolling surface of the rollers and the outer surface of the walls of the extendable sections are assigned the technological gap δt(see Fig.6), which compensates the error of fabrication and deformation of the boom under load, and eliminating various kinds of jamming.

The presence of technological gap δtcauses under load vertical movement of the extension section relative to the supports is Oh, especially significant in the area of the end "p", see 11, with the possible unwanted contact surfaces of the sections. To limit these movements and reduce friction in the area of possible contact at the end of the drawer is installed pads 47, made of a material with a low coefficient of friction, such as bronze. If significant contact pressure pads can be made of high strength material such as steel, with anti-friction coating on the interacting surfaces, for example disulfit molybdenum, deposited on the surface "p".

At the bottom of the portal 18 is made hatches (open) "C", see Fig, closed lid 48, rigidly connected with the housing of the portal screwed. In the Central part of each cover fixed pin 49 which, when the cover is placed in the cavity of the portal. At the end of the pin 49 through the bearing 50 has a roller 51, with the necessary structural gap δtobetween the annular track "t" anchor section 24 of the boom and the outer surface of roller 51. Thus in the portal formed by the discharge mechanism of the rotation mechanism.

In the transport position engineering UGM tooth-loosening 34 is located above the arrow, as shown in figure 1, excavation bucket 33 is maximized to the tooth-Ripper 34, providing the lowest longitudinal dimensions is down and increasing its maneuverability.

It should be noted that in strelba engineering caterpillar machines can be used and the previously mentioned exchangeable bodies, such as planning the bucket or blade, which will give the machine to lay the patrol road and to ensure the maintenance of roads, including the military.

The engineering of a caterpillar.

Thanks to the use of tank crawler off-road chassis with radiation, chemical and cannon-proof protection, the crew of the machine can operate in combat conditions and in emergencies, such as accidents involving radiological contamination areas. When using the machine in terms of shelling rotation device and its drive as external work items, removal of lesions which to perform the most difficult, protected by a shutter housing 14.

Before using those equipment deployed on the rotary device located in front of the cabin. The jib by means of a hydraulic cylinder 22 is installed in the required working position. For excavating his bucket hydraulic cylinder 35 turn from arrows, and the tooth-loosening 34 of the hydraulic cylinder 37 is removed to the boom In this position excavation bucket 33 is ready to work straight shovel, having the opportunity to lead ellerine work by hydraulic cylinders 22 and 35 on the high slopes (including career), or getting the soil in the area of the jib 31 pull-out section of the boom.

For excavating bucket 33 reverse shovel boom 23 by using the rotation mechanism 28 revolves around its axis at 180°. In this position the boom system excavation bucket 33 is ready to work for excavation of trenches, pits and theparade with the cylinders 22 and 35 in such work to fill the bucket used the movement of the back pull-out section 25 of the hydraulic cylinder 44 teleskopowe.

When the machine is in operation, for example when parsing a dam or barrage, there is a need to pull out of the ground or artificial base fragments of building structures or long objects (beams, rails etc). In some cases, you must first loosen their fastening (pinched) by "loosening". For such cases, use the capture-tick the working body, which is formed by joint or separate turning to each other tooth cultivator 34 and excavating bucket 33. Thus fragments of structures or long things zaselyaetsya between shovel excavating bucket 33 and tooth Ripper. In case of long object is located at an angle to the horizon, capture-tick the working body forms a grip in the same inclined position by means of the rotation mechanism.

When performing R the bot pick up-tick working body (or excavation bucket 33 in the reverse shovels), including the parse forest or urban rubble, when you want to pull retractable jib section in the reference section while turning her around the axis of the rotation mechanism, acting along the axis of the boom high load lock onto the rollers 51. Thus, in the present invention is provided with a low value of rolling friction between the annular track "t" anchor section 24 of the shafts and rollers 51, which allows efficient use of power and mechanisms of rotation to rotate the boom.

If necessary, carry out the lifting operations the machine can be used as a crawler crane thanks to the hook suspension 43.

When operating the boom system, particularly with a minimum departure drawer arrows, unidirectional pull-out section relative to the rollers of the roller supports 26 27 leads to the exhaustion of the technological gap δtwith the formation of angular displacement (tilt) axis pull-out section relative to theoretical axis of the boom. Install pads 47 on the outer side walls of the drawer arrows retains the technological gap δtpreventing the aforementioned bias. However, in such cases there is a sliding pads 47 on the inner surface of the walls of the base section 24. The execution of the strip of material with low coefficient the friction for example bronze or ductile material with a low friction coating on interacting with the wall of the stationary section of the surfaces reduces the friction in this area, ensuring the normal operation of the boom system.

It should also be noted that in the process of excavation on excavations ladle act of cutting forces influencing the retractable section of the boom rests on the rollers 26 supports "K" and "m" (27). These bearings take the load when the boom with a lifting hook suspension 43 as a lifting device. And because of support "K" and "m" are posted to the maximum distance possible in the dimensions of the boom, the impact of curly cut "and"necessary for placement of brackets 39 and cylinders 37, has practically no influence on the load on the boom system.

Thus the invention solved the task, namely expanded functionality engineering caterpillar machine and the boom system, and increased the security of a turntable from the means of destruction.
