Balance lifter used for vehicle maintenance

Abstract

The invention provides a balance lifter used for vehicle maintenance. The balance lifter comprises a lifting supporting base, a lifting device and a power device, wherein a to-be-lifted heavy object is placed on the lifting supporting base; both the lifting device and the power device are mounted on the lifting supporting base; the lifting device is used for enabling the lifting supporting base topull the heavy object to perform lifting motion; the power device is used for providing power to work of the lifting device; the lifting supporting base comprises an upper supporting base, a lower supporting base and a mounting bracket; both the upper supporting base and the lower supporting base are of circular plate body structures which are horizontally arranged, and the two are coaxially arranged; the lifting device is arranged in an area between the upper supporting base and the lower supporting base; the lifting device comprises a connecting bracket, a lead screw and a lifting mechanism; the lead screw is used for receiving power provided by the power device and transmitting the power to the lifting mechanism; and the lifting mechanism is used for pulling the upper supporting base to perform lifting motion in a direction perpendicular to the ground.

Description

technical field [0001] The invention relates to the field of lifting and lowering of heavy objects, in particular to a balanced lifting device. Background technique [0002] The jack is a commonly used tool in the maintenance of vehicles. Commonly used jacks generally use mechanical or hydraulic methods to drive the jack up and down to lift the vehicle. However, mechanically driven jacks require personnel to keep shaking the joystick to lift the vehicle. , Time-consuming and labor-intensive, while the structure of the hydraulically driven jack is relatively complicated, and the manufacturing cost of the jack is relatively high. Contents of the invention [0003] In order to solve the deficiencies in the prior art, the object of the present invention is to provide a kind of balance lifting equipment to solve the problems mentioned in the background above. There are four groups, so that the lifting force received during the lifting process of the heavy object is balanced. I...
