Replacing equipment for bogie of subway train

Abstract

The invention relates to overhaul equipment for a subway train. The equipment is used for replacing a bogie, which goes wrong, on the subway train. The equipment is characterized in that supporting devices 1 are arranged on a ground foundation equal to a subway train ground rail 24 in height and are located on the lower parts of the two sides of a subway train body 22, an electric flat carriage 2is arranged in a pit, a screw elevator assemblies 3 are arranged below the electric flat carriage 2, the electric flat carriage 2 can be enabled to ascend or descend according to the needs, when the electric flat carriage 2 is in an ascending state, the electric flat carriage 2 is used as a rail for the subway train, and when the electric flat carriage 2 is in a descending state, the electric flatcarriage 2 can transversely run along a running rail 21 and move out of the subway train so as to replace the bogie.

Description

technical field [0001] The invention relates to maintenance equipment for subway trains, which can conveniently and quickly replace bogies on subway trains where problems occur. technical background: [0002] The subway train bogie is an important part of the subway train, and the operation safety of the bogie affects the operation quality of the subway train and the safety of passenger transportation. The subway train bogie is the direct bearer of train traction power and vehicle load. Therefore, during the operation of subway trains, special attention is paid to the operation safety of the bogie. [0003] The subway train bogie is composed of current collector assembly, driving device, foundation braking device, traction device, primary spring, secondary suspension device, wheel-to-axle box device, frame and other components. Each component is composed of many parts. An organic assembly, such as a wheel-to-axlebox device, is composed of many parts such as wheels, axles, ...

AI Technical Summary

Problems solved by technology

But there are also disadvantages: first, the pit-type car crane lifts the entire subway train, which requires relatively high investment costs and occupies a relatively large area

Second, when replacing the bogie with a pit-type hoisting machine, the entire train needs to be erected to a certain height. There are many hoisting units and the equipment is relatively complicated. Any problem with any of the hoisting units may affect the normal replacement operation. carry out, the failure rate is relatively high
