Design of Socket-type Adjustable Support Device for Large Components of Harbin Metro Car Body

Abstract

This article focuses on the problem that when CRRC Changchun Railway Vehicles Co., Ltd. produces Harbin subway car body steel structures, the roof, chassis, side walls, end walls and other large components need to be finely processed after welding. If traditional horse stools are used for support, it will not only be bulky and the height cannot be adjusted, but also the operator comfort is not high and the work efficiency is reduced. In order to solve this problem, improve production efficiency and save manpower and time costs. We set up a joint research team. After investigation, analysis and demonstration, we developed a plug-in adjustable support device for large subway components. The device can be adjusted in height and width, and the device is light and easy to move and store, with obvious noise reduction and shock absorption effects. It meets the safe production of various types of subway car body steel structures.
