The invention relates to the field of lifting equipment, namely, loaders, mainly timber, created on the basis of tractors, equipped with appropriate hydraulic lifting means manipulator type.

Known for a number of analogues of the invention, both domestic and foreign developments (see, for whom ecii, B 65 G 67/12 and B 62 D 61/10 from 15.09.94 and 26.09.94, Express information about them is given in the relevant publications 3.69.32 P, 3.69.33 P, 7.69.37 Paragraph on page 4 and 5 of the RJ 69 “Technology and equipment for forestry, woodworking and pulp and paper”, No. 3 and 7 for 1995 and publications 9.60.68 P-9.60.71 Paragraph on page 7, 8 RJ 60 "Construction and road machines No. 9 1997, M: VINITI, and others).

These known cargo handling facilities on tractors are a highly specialized group of lifting and handling machines.

Some of them are used as Autonomous loading of modules, while others are equipped with the appropriate cargo platforms, often towed type, limiting the maneuverability of the machine in production areas with narrow passages and small (cramped) working sites.

A number of these known machines is quite complicated in design and have insufficient stability against tipping during loading and unloading when separated from the cargo platform, and in many other fixation of the boom and pivotally suspended therein of the relevant working body mounted on a frame of the tractor GRU is on rough terrain and sharp turns, facilities maintenance and other

The limited size of the rear semi-frames most of its tractors General purpose greatly complicates the Assembly of the lifting means manipulator type with multiple arrows and the corresponding hydraulic actuator, as well as the formation of the necessary grounds maintenance and other

From among the known analogues of the proposed technical solution closest (prototype) can serve as forest handling machine TM-51 Solombala machine-building plant, Arkhangelsk), General view and description of which is shown in Fig. 6 and pages 27, 28 journal of Building and road machines No. 2, 2001, M, LLC SDM-Press".

The specified machine is a truck forest type containing self-propelled chassis, made on the basis of tractor T-150K timber complete with supporting frame consisting of articulated between the front and rear semiframes placed on the rear section of the reducer output shaft of the engine with independent drive, tow hitch with attached cargo platform, made on the basis trailer-dissolution XTL 9362-013, remote outrages, located between the cab and crane support for fixing the folded boom and grapple in the transport position, and electro-hydraulic drive with oil tank, pump, control equipment remote work outriggers and manipulator and the corresponding connecting the hydraulic and electric lines.

Hydraulic crane SF-L supplied located by adjustment of the spatial position of the lifting section of the boom at the upper end of the bar his turntable headlights lighting grapple and workplace.

Lateral stability of the machine TM-51 when the manipulator is provided with a mechanical lock semiframes tractor and one pair of inclined extension of the outriggers with tilting base heels, posted on his rear end in the area of installation of the manipulator. To a great extent also contribute to the presence on the front of the tractor pusher, which in this case can be lowered to the ground, and attached to the towing towing device is rather heavy cargo platform.

In the transport position, the lifting and remote sections of the yoke manipulator motion and recorded a grapple on a support by means of capturing shrinking jaws, the latter formed in its top for this bracket, oriented in the longitudinal direction.

Without loading platform machine TM-51 are used as the appropriate handling of the module.

However, the practice of operation of such modules shows that in some cases they have only one pair of outrigger outriggers may not provide reliable stability from tipping over when the manipulator. This circumstance is due to insufficient spatial development generated when the basic contour of the truck.

The mounting of the manipulator directly on the spinal rear spars semi-frames of the tractor may cause excessive loading during loading and unloading their top and bottom shelves with a local deformation of the latter in the areas of attachment due to the lack of moment resistance of the cross-section spars effects of these loads. Local reinforcement of these side members by welding or attaching to them using bolted connections of the respective amplifiers are not allowed, as a rule, the developer of the tractor, not allowing drilling any holes or weld, polygranular SF-L mechanism coupled between the lifting and remote sections of his arrows, and especially the fixation of the latter and pivotally suspended on her grapple in the transport position, do not provide rigid fixing them when driving. The working fluid in the piston and rod cavities of the hydraulic cylinders of the lifting actuator, extension and telescoping sections of his arrows and jaws of the grapple in the transport position must be securely locked. In case of leakage, but also because of the rather large mobility of the connecting links pivotally connecting the grapple arrow, the latter under the action of traffic loads, especially when driving on rough terrain and sharp turns can vary accordingly in the vertical plane and the lateral direction with a sufficiently large amplitude. These fluctuations of boom and grapple accordingly transmitted to the cylinders. And since the boom and grapple have quite a large inertial mass, the force on the cylinders in the best case, can lead to premature wear and a corresponding reduction of their service life, and at worst to the emergency destruction of the structure of the manipulator.

Flexible hoses of the hydraulic manipulator generated is routed directly to the roof of the tractor cab and can cling to have it fill units or any constructive tabs when translating machine in working position can lead to their breakage.

Because of the limited size of the rear semi-frames of the tractor, as well as features of the structural design and layout support for fixing the boom and bucket of the crane in the transport position, the service area of its lower part is extremely cluttered, and forming there the necessary special sites, providing easy access to the manipulator, is almost impossible.

Implemented in machine TM-51 location lighting spotlights on the lifting section boom manipulator allows their spatial adjustment only before starting work. However, oriented appropriately headlights, performing loading and unloading operations are not always able to provide the necessary lighting grapple and work site, as specified section of the boom when it changes its spatial position, and the operator has no access to an appropriate adjustment.

The present invention is to simplify the design of the inventive loader and improve its performance.

In accordance with sabreteam the design of the rear semi-frames his self-propelled chassis, outrigger outriggers and manipulator, the layout and mounting of the latter on the rear section, the scheme of laying and fixing the boom system of the crane in the transport position, the hydraulic outrigger outriggers and manipulator and the corresponding electrical equipment, as well as the formation on the rear section of the chassis is necessary grounds maintenance, to provide easy access to the manipulator and other

In connection with the modification of the rear semi-frames 47 self-propelled chassis 1 of the inventive loader tow hitch 6 and the corresponding lighting devices 18 of the specified chassis moved to the back wall 42 of the extension attachment 34 modified his rear semi-frames 47.

Works claimed loader as follows. Upon arrival at the place of loading or unloading, the operator selects the optimal position of the truck, providing convenience and the greatest work from one installation, places it in the selected position, puts on the Parking brake and moves into position.

Handling of the inventive loader are usually made with outriggers.

In the design of the inventive loader to create the necessary reference circuit uses two respective reference module 7, 8, formed on the basis of the extension of the outriggers on the patent 2124993, B 60 S 9/02, 66 23/78 from 20.11.2001,

In the original (transport) position of the legs 68, 69 remote outriggers 7, 8 of the truck turned the supporting abutments 70 up and fixed by pins 71, is inserted into the corresponding holes 179 in their body and retractable beams 66, 67, pushed to the end of its internal counter with the two-position retainers 64, 65.

Translation outriggers 7, 8 from transport to working position is as follows. First, by extracting the pins 71 of holes 179 retractable beams 66, 67 and swivel legs 68, 69 respexit last. After the released of the legs 68, 69 are in balanced condition relative to the axis 180 of rotation.

This balancing is achieved by the fact that due to the weight of each of the turning of the legs 68, 69 moments are balanced by corresponding opposing them moments, exercisable providermetadata elements 181 spring type kinematically connects the above-mentioned paws with retractable beams 66, 67.

Then the legs 68, 69 manually turn relative to the axis 180 180down and fixed by pins 71, entered into the corresponding holes 182 their metal and retractable beams 66, 67.

After fixation of the legs 68, 69 in this position manually turn Samoobrona handle 183 dip clamps 64,65 around their longitudinal axes (in circumferential direction). When turning these handles 183 beams 184, kinematically interacting with their pins 185 with inclined bevels 186 buildings 187 clamps 64, 65 and cover soprotivlenie. After the bolts 184 out of engagement with the sliding beams 66, 67 their separat in this position by setting the pins 185 on flat anchor-mounting pads 191 buildings 187 clamps 64, 65.

Folded into a compact unit the arrow 10 by means of hydraulic cylinder 198 is lowered onto the cradle 105, 106 of a support 12 with the input of the installation pins 109 its lifting section 112 in the receiving boxes 108 and resting on their bottom 132 and subsequent lock (locking) of the outputs of them using mechanical shutters 107 and grab 11 freely stack one of its ends 133 on sloping backrest 134 protective wall 101 specified support and fix it quick-release mechanical lock 135. When placed on the area teleskopowe boom manipulator 10 9 flexible hoses 136 connecting hydraulic highways 15 for supplying working fluid to grapple 11 are stacked on the supporting visor 137 pillars 12.

Then translate the control knob 196 three-way valve 164 in position I (“Moving bearing abutments 70 swivel legs 68, 69 remote eutrigla 68, 69.

Then the corresponding displacement control knobs 166 hydraulic blocks 162, 163 serves the working fluid through the respective connecting hydraulic line 15 in the rod end 204 of the rotary cylinders of the legs 68, 69 remote outriggers 7, 8. Under the action of pressure fluid to the piston rods of these cylinders is rigidly bonded with them a self-supporting abutments 70 upwards.

Then remove the pins 71 of the holes 182 in metal retractable beams 66, 67 and legs 68, 69 and turn the last manually relative to the axis 180 180up with the subsequent fixing them in position by means of these pins, the insertion into the holes 179.

Then manually turn Samoobrona handle 183 dip clamps 64, 65 around their longitudinal axes. When turning these handles 183 beams 184, kinematically interacting with their pins 185 with inclined bevels 186 buildings 187 clamps 64, 65 and overcoming this resistance of the springs 188, forcibly removed from their respective holes 195 in the side walls 190 retractable beams 66, 67. After the bolts 184 out of engagement with the sliding beams 66, 67 their separat this is 64, 65.

This retractable beams 66, 67 are mechanically recipename with stationary guide rails 63 of the support modules 7, 8, and handle 183 these clamps 64, 65 is oriented vertically.

The retraction of the beams 66, 67 with a raised swivel legs 68, 69 back carried out by an appropriate move them manually in the stationary rails 63. When moving these beams 66, 67 simultaneously in the same directions of translational move and mechanical plungers 194, kinematically interacting with their Cams 193 located on their way unbent ends 192 handles 183 clamps 64, 65.

In the specified handle 183 clamps 64, 65 accordingly automatically rotate the plungers 194 around their own axes.

When turning the handles 183 clamps 64, 65 pins 185 beams 184 slips off flat support mounting pads 191 their housing 187 and these beams under the action of spring 188 rush back to rest on the outer surfaces of the side walls 190 retractable beams 66, 67. From this point in the process of further movement of the sliding beams 66, 67 bars 184 clamps 64, 65 are constantly in contact with the outer poverty, automatically drop into them and securely separat beams in the extreme retracted position (see Fig.31). Such retainers quite simple in design and convenient in operation, as part of the relevant business transitions associated with the management of their work is performed in automatic mode.

In principle, instead of the considered two-position clamps with a semi-automatic mode of operation for locking retractable outrigger beams outriggers can be used and simpler clips of the same type with manual transmission (see, for example, Guide designer-mechanical engineer, B. I. Yuriev, T. 1, M.: engineering, 1999, BBK 34. AG, A73 motorway, UDC 621.001.66 (035), page 753, sec. 10 “Clamps with extractor handle for tool accessories”).

After that, switch off the engine self-propelled chassis 1 with the hydraulic drive pump 14 offline support modules (remote outriggers) 7, 8 of the manipulator 9.

Instead outrigger outriggers on patent 2124993, B 60 S 9/02, 66 23/78, from 20.11.2001, in the design of the inventive loader without any restrictions can be used also any other, for example, patent 2116210, B 60 S 9/02, 66 23/78, from 27.07.98, with a crank mechanism to rotate the clutches, with Pogruzchik can move the load forward, ago and in any lateral direction. Because of this it does not require extensive passages on the places of loading and unloading and large industrial sites.

In the design of the inventive loader is used widely applied in kranostroenii domestic materials and components, rational technical solutions and standard manufacturing techniques.

With this in mind, as well as the relevant requirements of the state for such products, it can be repeatedly reproduced developed by him documentation in terms of serial production at specialized engineering plants with the necessary equipment, personnel and appropriate regulatory resolution database.

Currently, JSC "NC Uralterminalmash" design documentation, which made a full-sized operating prototype of the inventive loader PL-75 on the basis of serial tractor T-150K industrial equipment with articulated carrier frame “Kharkov tractor plant” and manipulator “Sinemorets-75” with a load moment of 75 kNconditions and unloading of vehicles (cars, short log trucks and other vehicles). If necessary, it can be used as an appropriate lifting-transport machines. It is enough to its towing towing device to attach the appropriate cargo platform.

The efficiency inherent in the design of the inventive loader technical solutions, as well as the possibility of obtaining by carrying out the invention the above-mentioned technical result consists in the simplification of the design and improvement of technical and operational qualities of the specified loader, supported by appropriate calculations and positive results of field tests.

These tests showed high dynamic qualities, maneuverability, reliability, ease of maintenance and repair, we offer forklift.

The decision to mass production of the inventive loader will be made after comprehensive testing it in real operating conditions in the respective farms timber industry.
