Primary repair technology for municipal railway vehicle

Abstract

The invention discloses a primary repair technology for a municipal railway vehicle. The primary repair technology includes the following steps that wheel-set tread diagnosis and pantograph detectionare performed; vehicles are cleaned, enters a garage for parking and are ready for power outage, after the municipal vehicle is parked well in the garage, preparation work is done before power outageof the vehicle, a ground rod is hung after it is determined that there is no power, and discharge operation is performed; no-power repair operation is carried out and includes vehicle roof equipment inspection, vehicle bottom equipment inspection, EIC system inspection and testing and filter net cleaning; power is supplied to the contact system, wherein a pantograph lands, and power is supplied tothe contact system after a ferry board withdraws and the ground rod is removed; power-on operation is performed and includes cab power-on inspection and test, passenger compartment power distributioncabinet inspection and vehicle-body two-sides inspection; equipment withdraws and the vehicle abnormal condition is inspected before the vehicle leaves from the garage, and the vehicle without the abnormal condition leaves from the garage. The primary repair technology for the municipal railway vehicle can adapt to the characteristics of rapid start and stop of the municipal railway vehicle for efficient and adaptive maintenance.

Description

technical field [0001] The invention belongs to the technical field of urban railway maintenance, and more specifically relates to a primary 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...

AI Technical Summary

Problems solved by technology

[0004] The current technical information mentions the maintenance process and specifications of high-speed railways, EMUs and subways. However, on the one hand, it does not involve the detailed procedures or details of the maintenance of urban vehicles at all levels, such as the specific operation process of the first-level maintenance. Or the details of the process, which parts need to be repaired for the first-level maintenance; on the other hand, compared with the national railway or subway, the main parameters and performance of the urban vehicles are different. The characteristics will inevitably cause the damage of its parts and components to be different, and the service life is also different. Copying the existing maintenance process is not only inefficient, but may even lead to in-depth and incomplete maintenance and poor applicability, which affects its operating performance and safety. influences
