Abstract

The invention provides a lifting device. The lifting device comprises two lifting components which are arranged oppositely, wherein the two lifting components are connected with each other by a supporting rod; each lifting component comprises a top frame capable of being lifted up and down; wheels on the two sides of a to-be-tested vehicle are respectively supported on the top frames of the corresponding lifting components. The lifting device disclosed by the invention is simple in structure, convenient to operate, capable of conveniently lifting vehicles and capable of solving the problem that the vehicles for different rail distances are hard to lift during a test in the prior art.

Description

technical field [0001] The invention relates to the field of vehicle testing, in particular to a lifting device. Background technique [0002] At present, with the vigorous development of railways, especially high-speed railways, more and more enterprises have gone abroad and moved towards the goal of global development. [0003] The development of globalization has also accelerated the pace of diversified development of enterprises. The number of vehicles of various gauges has increased, from 1000mm gauge to 1676mm gauge. Vehicles of different gauges cannot use the current domestic standards when performing equalization tests and flexibility coefficient tests. The test platform of the gauge can only be lifted by hydraulic jacks on temporary platforms. This test method is time-consuming, labor-intensive and inefficient. At the same time, there are certain safety hazards, which cannot meet the growing needs of enterprises. Contents of the invention [0004] The main purpo...
