The technical solution adopted for the present invention to solve the technical problems is:
A kind of wrecker of width-adjustable joint is lifted mechanism, comprise coupling assembling, lift stand, lift bar and first retractor device, the described bar of lifting comprises forearm and travelling arm, described travelling arm telescopically is sleeved on the forearm, the front end assembling fork frame mechanism of described travelling arm, described coupling assembling one end is connected with hoist mechanism, one end and the described forearm of described first retractor device are hinged, described lift stand comprises carriage, two sliding beams and two supports, described carriage is connected with the other end of coupling assembling, described carriage two ends are the sliding beam of telescopically suit respectively, described sliding beam is connected with support, and second retractor device, one end is connected with described carriage, and the other end of described second retractor device is connected with described support, described support and described forearm are hinged, and the other end of described first retractor device and described support are hinged.
Further, sell between one end of described first retractor device and the described forearm and be connected, sell between the other end of described first retractor device and the described support and be connected, sell between described support and the described forearm and be connected, sell between described second retractor device, one end and the described carriage and be connected, be connected for pin between the other end of described second retractor device and the support.
Further, the cross section of described travelling arm is non-circular.For example square, oblong etc. form sliding pair and prevent rotation as long as cooperates between travelling arm and the forearm.
Further again, described coupling assembling comprises pedestal, and described pedestal one end arranges bearing pin, the other end of described pedestal arranges sleeve pipe, described hoist mechanism is installed in rotation on the described bearing pin, on the described carriage turning block is set, and described turning block is nested in the described sleeve pipe rotationally.Certainly, coupling assembling also can be selected other modes for use.
Described first retractor device, second retractor device are hydraulic telescopic device.Certainly, also can be electronic or pneumatic other modes that waits.
Beneficial effect of the present invention mainly shows:
1. it is scalable to lift mechanism's width, is applicable to the vehicle of different in width;
2. lift mechanism's mode of operation and lift from both sides for lifting bar, even the full-sized bus after the very low sport car in chassis and front-wheel lean on can not collide its bumper/spoiler bottom, be applicable to the vehicle of different chassis heights yet;
3. both sides are lifted bar and are driven respectively by two retractor devices, and height can be regulated respectively;
4. when not working, lift stand and lift bar and can drive be shunk by retractor device makes and lifts device volume and shrink, and conveniently exercises at road;
5. wrecker can be realized turning to travelling in dragging the accident vehicle traveling process;
6. lift and be connected simply between mechanism and the former wrecker, former wrecker basic structure is changed few, and can be convenient for changing;
7. carriage mechanism can be tire bracket, axletree crotch or steel plate crotch, to adapt to dissimilar accident vehicles.
