Brake disc dismounting device

Abstract

The invention relates to a brake disc removal device. The removal device includes an oil cylinder, a piston, a connecting body, a piston rod, a support rod and a handle. The oil cylinder and the piston are installed coaxially. The piston is installed on the inner wall of the oil cylinder. There is an oil cavity, and the outer wall of the oil cylinder is provided with an oil injection hole that communicates with the oil cavity; the upper part of the oil cylinder is provided with a limit plate, which is fixed to the upper end of the piston, and the lower end of the oil cylinder is fixed to the connecting body and the support rod in turn; the piston rod is from top to bottom. The bottom passes through the inside of the piston and the inside of the connecting body in turn, the upper end of the piston rod passes through the limiting plate and is connected with the handle, and the lower end of the piston rod is provided with a threaded structure. The dismantling device uses an oil cylinder to provide dismantling power, and a linkage device is formed by a piston, a limit plate and a piston rod, which can greatly improve the dismantling efficiency of the brake disc; the support rod is detachably installed at the bottom of the connecting body, and inserted into the bolt of the brake disc holes to ensure stable disassembly work, and the number of installation support rods can be adjusted to meet the disassembly requirements of different types of brake discs.

Description

technical field [0001] The invention relates to the technical field of rail vehicle braking, in particular to a brake disc removal device. Background technique [0002] The brake disc is an important part of the tram braking system. The brake disc and the brake together provide the braking force for the tram to ensure the safety of the train operation. Usually, the center of the tram brake disc is provided with a threaded hole, and the edge of the brake disc is provided with a plurality of bolt holes. There are basically two ways to install the brake disc of a tram, one is to install and fix directly to a fixed part through bolts; the other is to connect through elastic cylindrical pins for positioning and anti-shearing effect, and then connect through bolts. Among them, the second installation method has a higher safety factor, but its disassembly and replacement are cumbersome, take up a lot of time, and easily delay the normal operation plan of the rail train.

AI Technical Summary

Problems solved by technology

Among them, the second installation method has a higher safety factor, but its disassembly and replacement is more troublesome, takes a lot of time, and easily delays the normal operation plan of rail trains

[0003] The existing brake disc removal tool has a relatively simple structure, and the disassembly process is manual disassembly, which is laborious and laborious, and its safety factor is difficult to guarantee
