Description

Technical Field

[0001] The utility model relates to the technical field of pantograph maintenance, in particular to a subway pantograph maintenance platform. Background Art

[0002] The pantograph is an electrical device that electric traction locomotives use to obtain electric energy from the contact network. It can be divided into two types: single-arm pantograph and double-arm pantograph. Both are composed of a slide plate, an upper frame, a lower arm (a lower frame for double-arm pantographs), a bottom frame, a pantograph lifting spring, a transmission cylinder, a supporting insulator, and other components. The pantograph is generally installed on the roof of a locomotive or EMU, and transfers the electric energy of the substation to the locomotive through friction with the contact wire. Since the pantograph needs to perform many measurement points, it is generally necessary to dismantle the pantograph and place it on a maintenance platform for disassembly and maintenance during maintenance.

[0003] At present, the operating placement table of the maintenance platform is fixedly installed. The placement height and angle of the workpiece cannot be adjusted during the maintenance operation. The mismatch between the placement position of the workpiece and the required maintenance height can easily cause omissions in the maintenance, resulting in incomplete maintenance. In addition, when inspecting other surfaces of the workpiece, the angle of the workpiece needs to be manually rotated, making the maintenance operation more cumbersome and inconvenient to inspect the workpiece.
