Abstract
The utility model discloses an underlying H-type front supporting device for hoisted vehicles, which comprises a rack, a vertical telescopic guiding body, a vertical lifting hydraulic cylinder, a lateral telescopic guiding body, a lateral telescopic hydraulic cylinder and a supporting body. When in work, the vertical lifting hydraulic cylinder extends out of the vertical telescopic guiding body, and then the lateral telescopic hydraulic cylinder which is hinged with the supporting body and positioned in the lateral telescopic guiding body extends out, thus forming a low-position landing status. The underlying H-type front supporting device for hoisted vehicles has the advantages of occupying small area, having small torque to crossbeams of vehicles, not only meeting the requirement of support span, but also not interfering the operation of crane jibs.
Description
Technical field
The utility model relates to a kind of underneath type H type front supporting device of lifting vehicle that hangs.
Background technology
Road is removed obstacles, and the vehicle and the weight thereof of motoring condition are removed voluntarily comprising being in for the main contents of rescue work, and hang when lifting in the road rotation of removing obstacles, supporting mechanism is one of chief component that guarantees wrecker main body and camp site safety, in the existing at home medium and heavy wrecker, the front supporting device of its rotation lifter structure, generally be divided into A type and H type, stretch out the transversal stretching hydraulic actuating cylinder of installing and locating on Che Liang during work earlier, stretch out the vertical lift hydraulic actuating cylinder again and form holding state, there is following shortcoming in this structure: 1, span is big to the moment of torsion that the car beam produces greatly; 2, the design take up room bigger, the corresponding increase of consumptive material; Therefore 3, because preceding support span is big, the scene of removing obstacles takes up room also greatly, and the loop wheel machine scope of work is produced to a certain degree interference.
The utility model content
The technical problems to be solved in the utility model provides little, the both satisfied support span requirements of a kind of moment of torsion little, that act on the vehicle crossbeam that takes up room, and can not cause again the arm operation is produced the underneath type H type front supporting device of lifting vehicle that hangs that disturbs.
For addressing the above problem, the underneath type H type front supporting device of vehicle of the present utility model comprises frame, vertically flexible director, vertical lift hydraulic actuating cylinder, transversal stretching director, transversal stretching hydraulic actuating cylinder and supporter.Be fixedly connected with vertical flexible director respectively at the two ends, the left and right sides of described frame, place the vertical lift hydraulic actuating cylinder in the vertical flexible director hinged with vertical flexible director bottom, place the external part of piston rod of vertical lift hydraulic actuating cylinder at two ends, the frame left and right sides hinged with the two ends of transversal stretching director respectively, be fixedly connected with the transversal stretching hydraulic actuating cylinder that oppositely is provided with mutually in the both sides, front and back of transversal stretching director respectively, on the external part of the piston rod of transversal stretching hydraulic actuating cylinder, be hinged with supporter.
The underneath type H type front supporting device of lifting vehicle that hangs of the present utility model, after vertical lift hydraulic actuating cylinder when work in the vertically flexible director stretches out, the interior transversal stretching hydraulic actuating cylinder of transversal stretching director that is hinged with supporter stretches out again, forms low level support ground state.
The underneath type H type front supporting device that hangs the act vehicle that utilizes the utility model to provide, make arm horizontally rotate the mutual interference of Shi Yuqian support the minimizing, also reduced the torsional moment of heavy burden to crossbeam, and the design space reduces significantly, saved consumptive material, having satisfied preferably removes obstacles hangs and lifts construction, thereby guarantees that this type of vehicle handles the scene of suing and labouring effectively, reliably, apace.
Description of drawings
Fig. 1 hangs the structural representation of the underneath type H type front supporting device of lifting vehicle for the utility model.
View when Fig. 2 stretches out downwards for the utility model hangs the underneath type H type front supporting device of lifting vehicle.
Fig. 3 hangs underneath type H type front supporting device holding state scheme drawing when work of lifting vehicle for the utility model.
The specific embodiment
As shown in Figure 1, the underneath type H type front supporting device of lifting vehicle that hangs of the present utility model comprises frame 1, vertically flexible director 3, vertical lift hydraulic actuating cylinder 4, transversal stretching director 6, transversal stretching hydraulic actuating cylinder 7 and supporter 9.Be fixedly connected with vertical flexible director 3 respectively at the two ends, the left and right sides of described frame 1, place the vertical lift hydraulic actuating cylinder 4 in the vertical flexible director 3 to captive joint with vertical flexible director 3 bottoms, place the external part of piston rod 5 of vertical lift hydraulic actuating cylinder 4 at two ends, frame 1 left and right sides hinged with the two ends of transversal stretching director 6 respectively, be fixedly connected with the transversal stretching hydraulic actuating cylinder 7 that oppositely is provided with mutually in the both sides, front and back of transversal stretching director 6 respectively, on the external part of the piston rod 8 of transversal stretching hydraulic actuating cylinder 7, be hinged with supporter 9.
The underneath type H type front supporting device of lifting vehicle that hangs of the present utility model, after vertical lift hydraulic actuating cylinder 4 when work in the vertically flexible director 3 stretches out, the transversal stretching director 6 interior transversal stretching hydraulic actuating cylinders 7 that are hinged with supporter 9 stretch out again, form low level support ground state.
