The invention relates to the field of lifting and transport machinery, namely the support-rotating devices (SDA) hydraulic cranes, mainly placed on the chassis of the vehicle.

Known for a number of analogues of the invention implemented in the construction of hydraulic cranes and other lifting equipment, both domestic and foreign developments (see, for example, ABT. mon. SU N 630207, B 66 C 23/86 from 30.10.78 ; N 704888, B 66 C 23/86 from 25.12.79; N A, B 66 C 23/86 from 07.04.83 ; U.S. Pat. N 3071265 U.S. CL 214-138, 1963 ; U.S. Pat. N 229640 Germany, B 25 J 17/00, 1985 and others).

Some of these known analogues are structurally executed on the basis of the rotation mechanisms with flexible chain type (ed.mon. SU N 630207, Pat. USA N 3071265), and other - based mechanisms for rotation with pinion gears of different modifications (ed. mon. SU N 660927, N 704888, N A, Pat. GERMANY N 229640).

In all of them as drive a manual transmission is used, as a rule, the hydraulic cylinders.

The known device on the basis of the rotation mechanisms with flexible transmission chain of the type used, for example, in the construction of forest manipulators firm "Johne Deer (USA). They are quite simple to manufacture and are relatively Namiki they have a limited angle of rotation of the rack arm, and their work is characterized by large variations of the stroke and the positioning error due to variability ratio.

Device with mechanisms for rotation on the basis of a rack and pinion gears are widely used in hidromanipulators technique to all countries involved in its production. This circumstance is due, in the main, well-developed element base and other well-known advantages of a rack and pinion gear.

In General, however, such devices have relatively large dimensions in the transverse dimension and considerable weight, and most of them are limited angle of rotation of the rack. Moreover, devices of this type due to the abrupt locking of the working fluid at the end of the stroke of the pistons of the hydraulic cylinders of the drive rail stop swivel in the extreme positions is hard enough, with considerable fluctuations designs that forces be used to reduce the dynamic loads of different system damping.

Some of the known devices with mechanisms of rotation on the basis of a rack and pinion gear are not limited by the angle of rotation of the rack. For example, the mechanism for auth. mon. SU N 660927 equipped for this device by the Ministry of health of the friction type. In addition, the implementation of such motion gear mechanical transmission mated with the rack by means of a splined connection with a travel height.

The above feature of the kinematic scheme of the considered device allows to increase the angle of rotation of the rack almost indefinitely by periodically removing gear from engagement with the rail and braking swivel with the subsequent return of Reiki in the initial position and the input wheel engages with it.

However, this rotation device has a rather complex kinematics and requires synchronization of the relative position of the teeth of the wheel and rail at the time of entering them engaged.

Widely used in industrial robots, for example type "Universal-5", MP and others (see "Mechanics of industrial robots," in three books edited by K. C. Frolova, E. I. Vorobyov. KN. 3 "design Basics".- M.: Vysshaya SHKOLA, 1989, BBK 32.816, M55, UDC 62-52, S. 222), and hydraulic cranes mainly light class with lifting moment of the order of 30 kNm and less are the mechanisms of rotation on the basis of worm gears.

Such mechanisms are compact, have the competitiveness of the transmission mechanisms of this kind are often used worm type gear.

However, transmission of this type is very sensitive to manufacturing errors, Assembly and deformation of the links under the action implemented in the operation of the loads.

For this reason, to eliminate the negative effects caused by the peculiarities of the structural design of such programs, it is necessary to take special measures, such as compensatory interchange, providing relative freedom of movement of the housing of the worm gear, within the above errors, and mounting clearances in the axial, radial and circumferential directions.

A turntable of the majority of known hydraulic cranes have remote outriggers, pivotally suspended at the ends of the retractable from the body frame to the Foundation beams. While the extension of these beams and the support legs of the outriggers is, as a rule, by means of specially provided for the cylinders (see, for example, application great Britain N 1465289, B 60 S 9/10 from 02.03.77; N 1496291, B 60 S 9/00, 9/12, 9/22 from 30.12.77 and Japan N 57-38460, B 60 S 9/12 16.08.82 ; N 1-195162, B 60 S 9/12, B 66 C 23/78 from 07.08.89 and others), and for translation of the outriggers from the transport position into the working position using special mechanisms, hydraulic, lever, is avci UK N 1467128, B 60 S 9/10 from 16.03.77 ; N 1577578, B 60 S 9/62 from 29.10.80 and others).

However, many of them are complex in their design, have a large mass and limit the angle of rotation of the outriggers. The latter circumstance severely constrains the layout of hydraulic cranes with such support and turning devices on the supporting frames of the chassis serial number of vehicles and complicates the protection of the outriggers in the transport position from exposure to road dirt, when they are positioned horizontally at the level of the chassis frame or below it. But despite this generally incorporated in their design the technical solution is justified for hydraulic cranes mainly medium and heavy classes.

For hydraulic cranes light class needed in such actuators no, because the necessary movement of the above items bearing slewing devices in most cases, you can implement manually.

However, to ensure the standard values applied to them manually efforts in some cases it is necessary to take special measures, for example, associated with the maximum relief roaming parts, reducing friction between them and other

The bolt 61 of the retainer 60 communicates depending on the location of the sliding beams with one or other of the two located on the same plane through holes 62, 63 in the side wall 64 (65) retractable beams 14 (15), exploded respectively the length and the profiled configuration of the cross-section of the bolt with providing compensation junction in the vertical direction.

Compensation junction is realized through the execution of holes 62, 63 in the form developed in the direction of the grooves.

Wall 64 (65) of each of the sliding beams locally supported along the contour of the holes 62, 63 by welding thereto on the inner side of the flat plates 66 of the required profile and thickness.

Each of the spring retainers 60 retractable beams 14, 15 are equipped with a mechanism 67 forcible withdrawal of the bolt 61 out of engagement with them, such as lever-wedge-type, and locking it in rosapenna position.

Mechanism 67 is made in the form of a perpendicularly mounted on vernichter 60, ending the final part of his rise flat abutment mounting platform 71 is oriented parallel to the longitudinal axis of the lever.

The lower section of each of the outriggers 16 are made in the form of a telescopic intermediate pipe 72 and raised from it support legs 73 with the possibility of discrete adjust the length of the extension and the last commit in any of the intermediate positions by means fastening them into one removable pin 74.

To avoid turning support legs 73 relative to the intermediate pipe 72 in the construction of the outrigger mechanism 75 of the fixing claws in the circumferential direction in the form of radially screwed into the screw hole of the wall 76 of the pipe stop screw, the shank of which is kinematically communicates with a vertically oriented guides keyed groove 77, made in the wall of 78 feet.

The top section of the outrigger is made in the form of telescopically mated with the intermediate pipe 72 of the housing 79, equipped with a screw mechanism 80 with hand lever 81, for example, lever type, providing infinitely variable forward movement of the intermediate pipe.

To avoid turning the roundabout direction in the form of radially screwed into the threaded hole of the housing wall, the stop screw, a cylindrical tip is kinematically communicates with a vertically oriented guides keyed groove 83, made in the wall 76 of the intermediate pipe.

Hinged to each of the outriggers 16 on the end of the extendable beams 14 (15) with the possibility of discrete rotating them in a vertical plane oriented in the longitudinal direction within 360oand fixing each of the intermediate positions by means of a removable pin 84.

For this purpose, the respective end face 85 of each of the sliding beams 14, 15 are formed oriented along them cylindrical connector 86, movably articulated with the response, the sleeve 87, perpendicularly fixed, for example by welding on the upper part of the body 79 of the outrigger 16.

In the body of the sleeve 87 and the connector 86 is executed napagod evenly spaced in the circumferential direction of the radial holes 88 under the removable pin 84 commit an outrigger 16 relative to the sliding beams 14 (15).

Each of the nodes articulated suspension of the outriggers 16 are equipped with a mechanism 89 longitudinal fixation of the mating parts 86,87 hinge, made in the form of screwed into the sleeve 87 of the housing 79 of the outrigger resis them in the same plane as the circular groove 92 on the exterior surface of the connector 86 retractable beams 14 (15). Due to the discussed features of the structural design of the nodes articulated suspension outriggers declare a turntable, they can be in the transport position, the supporting paw up. In this position the outriggers are in the safest and most favorable operating conditions of the area, high above the ground, and when the vehicle is not practically thrown dirt road.

In principle, in the transport position, they could be located at different angles to the horizon both above and below the plane of the setup declare a turntable manipulator. This feature of the structural design of the outriggers claimed turntable manipulator significantly expands the range used for the accommodation of vehicles.

They are not difficult to manufacture, compact, are light-weight, convenient and safe in operation. As with the sliding movement of the beams, to translate them from the transport position into the working position and Vice versa does not require stand-alone hydraulic drive, because all related operations are performed manually with the appropriate requirements the node 17 of the body frame 4 of the base 3 is carried out by means of bearings 18, 19, 20 and the axial - end support 21.

Mechanical bearing 21 of the combined bearing unit 17 is made in the form placed in the annular groove 93 of the housing 4 of the frame base 3 flat split spring retaining ring in contact with the face 94 of the stationary ring 95 of the lower radial-thrust bearing 20 mounted on the shank 96 of the rotary stand 22 with rings 97 similar design, interacting with the butt of the rolling ring 98 of the same bearing.

The bearings 18, 19, 20 and end bearing 21 provide the necessary freedom and ease of rotation rack 22 when the mechanism 24 of its rotation. However, due to their immobility end bearing 21 of the combined bearing unit 17 does not participate in the rotation rack 22. For this reason, it is practically not subjected to wear and has no predisposition to mechanical gouging the working surface.

The rotary stand 22 are provided with rigidly fixed on it, for example by welding, thin-walled protective visor 99, shielding the upper part mounted worm gear 26. When this welding visor 99 swivel 22 is made of two joined together when Monta is profilirovannymi contour 104 mating with them part 105 hours.

The specified technical solution is easy to implement and eliminates the direct hit of precipitation, as well as fine and other mechanical particles moved to the upper part of the gear 26 of the rotation mechanism 24 of the claimed device and accumulation in local depressions of the condensate and dirt.

Each of the pins 74, 84 of the fixed structural elements provided with a locking mechanism 106 of the lock against unauthorized falling out, for example, a spring type.

To the outer side walls 107, 108 both support beams 12, 13 in the zone location of the swivel 22 and at the opposite end of one of them, in the distance, caused by the base of the spinal location of the side members 109, 110 chassis 2 of the vehicle, welded mounting-mounting brackets 111, 112, 113 developed in the transverse direction through vertical channels 114 for passage of a fastener 115.

Each of the mounting-mounting brackets 111, 112, 113 attaching a turntable to the spinal rails 109, 110, the chassis 2 of the vehicle is made of two spaced between ripoarisch racks 116, 117 polytrichales configuration C is open at the top and bottom flat box and adjacent to the side wall of the supporting beams plate 118 of the bracket is cut from the bottom to the radius of the bend of the box beams to provide the necessary quality of the seam of her welding.

The length of the through channels 114 in the mounting-mounting brackets and base between them in the transverse direction is made with the possibility of mounting a turntable on vehicles with different width dimensions spar frame chassis.

Works declare rotation device of the manipulator, as a rule, made by the outriggers 16.

To transfer them from the transport position into the working position first turn cylindrical lever mechanism 68 67 latch 60 either of the two retractable beams 14 (15) in the circumferential direction.

When turning the lever 68, kinematically interacting with an inclined bevel 69 of the housing 70 of the retainer 60 and overcoming this resistance of the spring 120, forcibly outputs the bolt holes 61 of the 62 retractable beams.

After removing the bolt from engagement with the sliding beam it separat by setting the lever 68 on a flat abutment mounting platform 71 of the housing 70 of the retainer 60.

Then, stoysin the lever 68 took him with the mounting pads 71.

When the gathering arm with the mounting pads bolt 61 under the action of the force of the spring 120 instantly goes back all the way to the wall of the sliding beams.

Upon further pulling of the sliding beams bolt is in constant contact with its wall and in the final position as soon as the hole 63 will at head with it, automatically Sasakawa it reliably stoparic beam.

In this position through the extraction of the pin 84 from the holes 88 you unhook parts 86 and 87 articulated suspension of outrigger 16 and by rotation around the longitudinal axis 122 of the transfer of the latter from the transport position into the working position supporting paw 73 to the bottom.

In this position, aligning the holes 88 in the parts 86 and 87 articulated suspension outrigger, again fixed between them by entering the pin 84 into the specified holes.

Upon completion of this operation by extracting the pin 74 of the holes 123 you unhook between the intermediate pipe 72 and the anchor claw 73 of the lower section of the outrigger 16 and, holding hands, push the paw of the intermediate pipe down until it touches the ground.

If in this position the mating holes 123 of the intermediate tube and feet do not match, then the last bit pripada pipe and paw are tightly bonded into a single link.

Then, using the manual actuator 81, through appropriate rotation of the lead screw 124 mechanism 80 of the upper section of the outrigger 16 is moved down kinematically coupled with it the nut 125 and rigidly associated intermediate pipe 72 with the control paw 73 to the last meeting with the ground.

On the exact same technology, carry out the removal and transfer to the operating position and the second outrigger 16.

Put the outriggers provide power to "unload" springs the chassis 2 of the vehicle and increase its stability when the manipulator 1 of lifting operations.

Ensuring the correctness and reliability of the exhibition support legs outriggers include the hydraulic motor 25 of the mechanism 24. Thus rotation of the output shaft of the motor is transmitted to the worm, the worm 126 of the gear 26, kinematically coupled with his wheel 27. Next, from the wheel 27 through the spline connection 28 it is reported to the rack 22.

Hour 22, turning in a combined bearing unit 17, provides movement of the hoisting boom 23 manipulator in the circumferential direction.

When the manipulator operations associated with the lifting, lowering and County weight of the boom system with a working body and the load, the reactive torque by turning mechanism of the rack, as well as efforts from outriggers.

Operating load, due to the action of bending moment and axial forces on the boom 23 is transmitted to the rotary stand 22.

The radial components of these loads are perceived by the bearings 18, 19, 20, and the axial force through the bearings 19, 20 - end support 21.

From the bearings 18, 19, 20, and mechanical support 21 these loads through force plate 5, 6 of the housing 4 and is rigidly bonded with them supporting beams 12, 13 are transmitted to the spinal side members 109, 110 chassis 2 of the vehicle.

The rotation rack 22 of a turntable in the reverse direction is the reverse of the motor 25, and a stop - off.

After termination, operating in the reverse order, translate extension outriggers in the transport position.

Declare rotation device is compact and has small dimensions in the transverse dimension, an unlimited angle of rotation of the rack and a sufficiently high weight perfection. His work is characterized by great uniformity and low positioning error.

In the engineering of domestic materials the best technical solution and standard manufacturing techniques.

With this in mind, as well as the requirements of the state for this kind of technique, it can be repeatedly reproduced developed by the documentation in the batch production at specialized engineering plants with the necessary equipment.

Currently, JSC "NC Uralterminalmash" declare rotation device developed detailed documentation, which made an experimental batch of these products.
