Five-stage overhaul process for urban region railway vehicle

Abstract

The invention discloses a five-stage overhaul process for an urban region railway vehicle. The five-stage overhaul process comprises the steps that a train drives back and enters a parking lot, a wheelset pantograph is detected, the train is washed, and reconditioning and detaining for overhaul are conducted; the train is transferred to a five-stage overhaul garage for decompilation, decompilationis conducted, and decompiled and decomposed parts are overhauled; an overhauled train body, a traction and electric braking system, an air-conditioning and ventilation system, an auxiliary power supply system, a train control and diagnosis system, an air braking and wind source system, and a train-mounted information and passenger information system are generally assembled to formed an overhauledtrain body; an overhauled wheelset axle box, an overhauled framework and an overhauled hanging device are assembled, and thus an overhauled and assembled bogie is formed; the overhauled train body and the overhauled bogie are mounted on the train; a single train test is conducted; the multiple single trains are marshaled and statically adjusted; the trains subjected to marshalling and static adjusting are dynamically debugged; static train delivery is conducted; and the trains are stored for standby application. The whole set of overhaul process flow suitable for five-stage overhaul of the urban region railway vehicle is put forward, and the efficient guidance for five-stage overhaul of the urban region railway vehicle is provided.

AI Technical Summary

Benefits of technology

This patented technology describes three ways that improve road train safety during repairs or modifications. Firstly it suggests providing comprehensive data about how well different types of cars behave under certain conditions before they break down safely. Secondly, it introduces new methods like advanced sensory technologies (AST) which help detect damage more accurately than previous techniques. Thirdly, there has been an improvement called Five Level Repair Protocols (FPR). These protocols aim at improving highway railroad fleet operations while reducing their impact upon environmental concerns.

Problems solved by technology

This patented describes how current methods used to perform road maintenance work involve combining planning repairs with post-maintenance tasks like balance checks. However, these techniques may be limited due to factors including incomplete documentation about the type(s) of infrastructure being maintained at each location within an entire city, lack of detail regarding individual types of cars involved, differences between train occupancy rates and operating times, and potential issues associated with older versions of certain parts. Additionally, some regulations require monitoring various aspects of the fleet regularly while keeping them under control. Overall, previous approaches had limitations when applied to new builds of roads without comprehensive understanding of what constitutes effective management practices.
