Vehicle lifting device used for highway field

Abstract

The invention discloses a vehicle lifting device used in the road field, which includes a lifting mechanism and a positioning and tensioning assembly, wherein there are two lifting mechanisms, and the lifting mechanism includes an L-shaped plate and a supporting shaft, wherein the horizontal sides of the L-shaped plate are front and rear There is a vertical board corresponding to the side; a lifting airbag is arranged between the two vertical boards, and 4 guide blocks are fixed on the front and rear sides of the horizontal lifting board corresponding to the strip guide holes, and the guide blocks slide with the corresponding strip guide holes. Cooperate; the supporting shaft is in contact with the outer surface of the tire when it is working, and the air intake pipes of the lifting airbags of the two lifting mechanisms are connected to the main air pipe, which is connected to the air compressor and supplied with air by the air compressor; the tensioning combination includes a horizontal Bolts and lock nuts; after the tails of the two horizontal bolts correspond to the bolt holes on a tension seat, the lock nuts are set respectively, and the two tension seats are fixed on the top surface of the horizontal lifting plate of the other lifting mechanism superior. The lifter can directly lift the tire, which is convenient, fast and labor-saving.

Description

technical field [0001] The invention belongs to the traffic field, in particular to a vehicle lifting device used in the road field. Background technique [0002] During traffic operation or traffic accident handling, it is often necessary to move vehicles. When the vehicle needs to be moved, it has been a long time to jack up the suspension first, wait for the two tires on one side of the suspension to be a certain height off the ground, and then insert a car mover with its own wheels under each tire ; After four tires are all supported on a car mover, the whole car will be lifted so that the follow-up mobile vehicle will be lifted. [0003] Since there is a shock absorbing spring connection between the suspension and the tire, the tire will tend to move downward under the action of the shock absorbing spring when the suspension is lifted, so most of the time in the front of the lifting process is to lift the suspension, and the tire It has not been lifted; only when the ...

AI Technical Summary

Problems solved by technology

It can be seen from the above statement that the existing method of lifting the suspension with a jack to lift the tire off the ground requires lifting the heavy suspension to a certain height, which is not only time-consuming and laborious, but also the suspension is raised higher, resulting in the overall The center of gravity of the car is high, which may cause safety accidents such as rollover, so it is urgent to solve the above technical problems
