In this way, the lead screw is subjected to compressive stress during work, which will cause the lead screw to bend after working for a long time, affecting the operation of the equipment
At the same time, installing the driving device on the top of the body will cause the overall center of gravity of the crane to be high and the stability is poor

The invention discloses a car lifting machine which comprises a vertically arranged machine body, a bracket mechanism which can move up and down along the machine body and is used for lifting a car body, and a lead screw vertically arranged in the machine body, wherein the lead screw is fit with a working nut; the working nut is fixedly connected with the bracket mechanism; the upper end of the lead screw is in rotational hanging connection with a top plate of the machine body; a driving device is arranged on a bottom plate of the machine body; an output end of the driving device is coaxial with the lead screw; and the lower end of the lead screw is fixedly connected with the output end of the driving device. The car lifting machine has the advantages that the car lifting machine is reasonable in layout and compact in structure, so that a space utilization rate can be increased; a transmission structure is high in bearing capacity and mounting accuracy, so that the transmission efficiency can be improved; a mounting structure of the lead screw is simple, and the lead screw is convenient to mount, so that the assembling efficiency can be improved and the maintenance of the lead screw can be facilitated; the eservice life of the lead screw is increased; and the service life of the car lifting machine and the safety of a system can be increased and improved.
Description
technical field [0001] The invention relates to the technical field of cranes, in particular to a crane. Background technique [0002] With the rapid development of the city, the traditional highway traffic has become extremely congested, and it is difficult to meet people's requirements for commuting and traveling. Rail transit has been vigorously developed due to the advantages of large carrying capacity at one time, many operating shifts, and collective control without congestion. [0003] In order to ensure the safety of rail traffic, after the rail vehicle has been running for a period of time, it is necessary to overhaul or replace the wheel set in the bogie and other parts of the vehicle bottom. During maintenance, the entire group of vehicles needs to be lifted to a certain height in order to replace the vehicle bottom. Bogies and other components. [0004] When overhauling, it is necessary to separate the carriage from the chassis by means of fixed lifting equipme...
