Vehicle lifting jack used in transportation field

Abstract

The invention discloses a vehicle lift used in the field of transportation. The cross section of a tire lift plate of a lifting trolley is an obtuse triangle, a supporting wheel fixing shaft is fixed at the obtuse angle of the tire lifting plate, and the supporting wheel fixing shaft is fixed at the obtuse angle. The front and rear ends of the elevator are respectively rotatably matched with a support wheel; the number of tensioning devices is two, and the tensioning device includes a first steel cable and a second steel cable, wherein one end of the first steel cable is connected to one of the lifting trolleys. The end of the fixed shaft of the supporting wheel is fixed, the other end of the first wire rope is connected with one end of the second wire rope through the screw sleeve screw assembly, and the other end of the second wire rope is fixed with a bar-shaped connecting block. The lifter can directly lift the tires, the lift height is very low, and the car shifter can be easily inserted into the gap between the two lifting trolleys; at the same time, the suspension is also raised synchronously with the tires, so as to avoid The height of the suspension is raised too much, so as to ensure that the center of gravity of the vehicle is not raised too much.

Description

technical field [0001] The invention belongs to the traffic field, in particular to a vehicle lifter used in the traffic 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 like this, so that the follow-up mobile vehicle. [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 , but the tires are not lifted; only when the suspension is l...

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. The center of gravity of the whole vehicle is high, which may cause safety accidents such as rollover, so it is urgent to solve the above technical problems
