Three-stage repairing process for municipal railway vehicle

Abstract

The invention discloses a three-stage repairing process for a municipal railway vehicle. The process comprises the following steps: detecting a wheelset pantograph after a train is collected and enters a yard; performing thorough cleaning on the vehicle; performing preparation and repair on the train; unmarshalling the vehicle body, decomposing the unmarshalled vehicle body into a vehicle body, atraction and electric braking system, an air braking and air source system, a coupler and a bogie, and continuing to decompose the bogie, and overhauling the decomposed components of the vehicle body,the traction and electric braking system and the air source system, the coupler and the bogie; assembling the vehicle body, the traction and electric braking system, the air braking and air source system and the coupler; assembling the overhauled bogie components to form an overhauled bogie; dropping off the overhauled vehicle to form a single vehicle; performing a single-vehicle test on the single vehicle; carry out marshalling static commissioning; performing dynamic commissioning; static vehicle delivery, and on-line operation after parking and waiting duty. The overhaul process is suitable for the characteristics of the municipal railway vehicles, and the process is comprehensive and reasonable.

Description

technical field [0001] The invention belongs to the technical field of urban railways, and more specifically relates to a three-stage repair process for urban railway vehicles. Background technique [0002] The purpose of vehicle maintenance is to maintain and improve the basic performance of vehicles, ensure safe and reliable operation, and reduce vehicle failures. In terms of maintenance of urban vehicles, it is advisable to implement a maintenance system that combines "planned repair + status repair + balanced repair". Planned repair and state-of-the-art repair belong to preventive maintenance, which is dominated by planned repair and carried out according to time and mileage; state-of-the-art repair is to determine the maintenance timing according to the actual technical condition of the equipment. Balanced repair is to use the window of vehicle operation and outage to carry out maintenance on trains during non-operating hours and off-peak hours, and disperse the mainte...

AI Technical Summary

Problems solved by technology

Therefore, the maintenance process of urban railway vehicles cannot completely copy the maintenance process of national railways and subways. It is necessary to make corresponding changes according to the characteristics of urban vehicles during maintenance. Therefore, a three-level maintenance process for urban vehicles is proposed here.
