A kind of maintenance auxiliary equipment for subway servo rack

Abstract

The invention relates to auxiliary equipment for maintenance of a subway servo frame, which comprises a bottom plate, guide rail frames and a lifting device, wherein the guide rail frames are symmetrically installed at the upper end of the bottom plate, the servo frame is arranged between the two guide rail frames, the lifting device is arranged above the guide rail frames, and the lifting deviceis installed on the bottom plate. The auxiliary equipment can solve the problems that when the subway servo frame is maintained by means of existing equipment, the servo frame cannot be effectively positioned generally, the disassembled servo frame is easy to deviate to affect the subsequence installation of the servo frame, and meanwhile, the machining efficiency of the servo frame is influenceddue to the fact that rollers of the servo frame cannot be quickly cleaned, and when the subway servo frame is hoisted by existing equipment, a lifting belt usually cannot be protected, and the servo frame is prone to falling off to affect the body safety of workers.

Description

technical field [0001] The invention relates to the field of maintenance of subway servo racks, in particular to an auxiliary equipment for maintenance of subway servo racks. Background technique [0002] The servo frame is the bogie, and the bogie is one of the most important parts of the urban rail vehicle. When the vehicle is running, it is subjected to the impact from the line, the lateral movement between the wheels and the rail, the vibration of the drive system, the wind pressure applied to the vehicle body, etc., resulting in vibration in all directions, including longitudinal, vertical, nodding, There are 6 types of lateral, shaking and rolling. When the wheel runs on the rail, it is required to run smoothly in a straight line and pass through the curve smoothly, reducing the stress acting on the rail and the vehicle, all of which have an important relationship with the structure of the bogie and the selection of system parameters. [0003] At present, the existin...

AI Technical Summary

Problems solved by technology

[0005] The present invention can solve the problem that the existing equipment cannot effectively locate the servo rack when the subway servo rack is overhauled, which leads to the phenomenon that the disassembled servo rack is prone to shift, which affects the subsequent installation of the servo rack, and at the same time does not The rollers of the servo rack can be cleaned quickly, which affects the processing efficiency of the servo rack. Moreover, when the existing equipment lifts the subway servo rack, it usually cannot protect the lifting belt, which leads to the phenomenon that the servo rack is prone to fall , affecting the physical safety of workers and other problems
