Description
Technical Field
The invention belongs to the technical field of mechanical disassembly and assembly, and particularly relates to an integrated device for disassembling and assembling a coupler buffer.
Background
The train coupler buffer device is a device for connecting two trains, is a very important part of the trains, and is divided into a coupler part, a buffer part and a round pin. The coupler part is used for connecting two trains, the buffer part is divided into a coupler yoke and a buffer part, and the round pin is connected with the coupler and the coupler yoke buffer to play a role in buffering when the two trains mutually impact.
The coupler buffer is a vehicle component for interconnecting a vehicle with a vehicle, locomotive or motor car, transmitting traction, braking forces and moderating longitudinal impact forces. The car body frame is formed by a car coupler, a buffer, a coupler tail frame, a slave plate and the like into a whole, and is arranged in traction beams at two ends of a car body underframe. In order to ensure the safety and reliability of the vehicle coupling and the interchangeability of the installation of the coupler buffer device, the regulations related to the railway rolling stock in China prescribe that: after the car coupler buffer is loaded, the height of the horizontal center line of the car coupler knuckle from the steel rail surface in an empty car state is 880mm (the error of +10mm-5 mm is allowed), and the truck is 880mm (+ -10mm). The maximum height difference of the horizontal central lines of the couplers of two adjacent vehicles is not more than 75mm. The coupler buffer is used for relieving longitudinal impact and vibration of the train caused by the change of locomotive traction force or the mutual collision of vehicles during starting, braking and shunting operation. The damper has a function of dissipating shock and vibration between vehicles, thereby reducing damage to the vehicle body structure and the loaded cargo. The operating principle of the damper is to alleviate the impact force by compressing the elastic member while absorbing impact energy by friction and damping during deformation of the elastic member.
Because of its importance, it is an important component that must be regularly serviced. In the railway freight car service project, the coupler buffer is one of the necessary inspection projects. The car coupler buffer is overhauled, and the car coupler buffer is detached from the vehicle for disassembly, overhauling and assembly. However, the hook tail frame is difficult to be integrally disassembled in the prior art due to the position of the hook tail frame and the strong precompression force of the buffer, so that the maintenance efficiency of the whole automobile is affected to a certain extent. The disassembly of the traditional 17-type coupler buffer usually adopts two different disassembly and assembly machines to disassemble or assemble the coupler and the coupler frame buffer respectively, so that the production efficiency is low, the labor intensity is high, and the potential safety hazard is high especially when the round pin is disassembled and assembled, and the requirement of safety production cannot be met.
