Universal transition device for center discs for urban railway vehicles

Abstract

The invention provides a center plate universal transition device for an urban railway vehicle and belongs to the technical field of transition connection of the urban railway vehicle and a fake trolley transportation device. The center plate universal transition device comprises an upper connecting board, a lower connecting board, a connecting seat and variable-diameter bolts. The upper connecting board is fixedly connected with a vehicle body connecting board of the urban railway vehicle through the four variable-diameter bolts. The lower connecting board is fixedly connected with the upper connecting board through the connecting seat. The center plate universal transition device can be used for more than thirty programs of all the carbon steel, stainless steel and aluminum alloy urban railway vehicles at the present stage. Only different variable-diameter bolts need to be remanufactured for the vehicles of different programs, only relatively small cost needs to be input at a time, and the problems that special center plates need to be repeatedly manufactured, the input cost is increased, and a production period is affected in the prior art are greatly solved. Meanwhile, the types of the center plates are unified, the multiple center plates of the same type can be stored in a centralized manner, and management, distribution, recording, use and transportation are convenient. The transition device has successfully passed a use test and has operability and popularization.

Description

technical field [0001] The invention belongs to the technical field of transition connection between urban railway vehicles and dummy transport devices, and in particular relates to a universal transition device for the center plate of urban railway vehicles. Background technique [0002] After the body of the existing carbon steel, stainless steel and aluminum alloy urban rail vehicles is completed, such as figure 1 As shown, the car body first needs to be connected by the car body connecting plate 1 and the special center plate 2 before it can fall into the fake trolley, and then the next process such as painting and assembly is carried out. combine figure 2 As shown, the car body connecting plate 1 is provided with four screw holes 1-1 on the car, and the connection lines of the holes of the screw holes 1-1 on the four cars form a rectangle, and the center plate 2 is provided with four center plate screw holes 2-1. 1. The line connecting the centers of the four center ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the existing technical problems that one type of center plate can only correspond to one project of urban railway vehicles, resulting in increased project costs, inconvenient management of many types of center plates, and inconvenient transportation of false trolleys after the car body is completed, the present invention provides a It is a universal transition device for the center plate of urban railway vehicles, which can make one center plate correspond to various urban railway vehicles, save costs, and facilitate the management of center plates and the transportation of fake trolleys
