Safety interlocking system suitable for urban railway vehicle maintenance warehouse

Abstract

The invention discloses a safety interlocking system suitable for an urban railway vehicle maintenance warehouse, which belongs to the technical field of urban railway traffic maintenance, and is characterized in that an on-off assembly, an access control assembly and a signal lamp guide assembly are arranged corresponding to each maintenance line; by utilizing the combined arrangement of corresponding parts in each assembly, the on-off control of the overhead line system and the switching and display of various maintenance states can be accurately completed, and the reliable isolation of a top climbing platform and a boarding platform when the overhead line system is powered on can be realized. The safety interlocking system suitable for the urban railway vehicle maintenance warehouse issimple in structural composition and arrangement form, can accurately achieve on-off control over the overhead line system, can synchronously achieve switching and display of various maintenance states, achieves isolation of the top climbing platform and the boarding platform when the overhead line system is powered on, avoids the occurence of safety accidents, guarantees the safety and reliability of climbing operation of maintainers, improves the efficiency and quality of vehicle top maintenance, and has good application prospects and popularization value.

Description

technical field [0001] The invention belongs to the technical field of urban railway traffic maintenance, and in particular relates to a safety interlock system suitable for an urban railway vehicle maintenance depot. Background technique [0002] With the continuous acceleration of the urbanization process in our country and the increasingly frequent connections between cities, the traditional form of rail transit has become increasingly unable to meet the needs of round-trip travel between cities. For this reason, urban railways have emerged as the times require. As a new type of rail transit, it generally has the characteristics of "high-density, small grouping, and public transportation" transportation organization, and most urban rail vehicles use AC to receive traffic, which is obviously different from traditional subways and high-speed rails. Because of this, the maintenance system for traditional rail transit (subway, high-speed rail) is often not directly applicable...

AI Technical Summary

Problems solved by technology

[0004] At present, most of the ground fixed work platforms are used for the maintenance of urban railway vehicles. The platforms and protective nets are relatively heavy and difficult to disassemble, occupying the ground maintenance work space, resulting in low maintenance efficiency

Moreover, for the traditional maintenance depot, maintenance personnel can only enter the driver's cab and passenger compartment from one side of the vehicle group for maintenance operations, and the maintenance personnel of the EMU in the market enter the driver's cab and passenger compartment relatively frequently for maintenance operations, resulting in maintenance further reduction in efficiency

At the same time, the existing maintenance system has poor compatibility with vehicle roof maintenance, making it difficult for the quality of vehicle roof maintenance to meet the requirements of actual operation

In addition, it is difficult for the existing maintenance system to provide sufficient protection when the vehicle is on the roof, and there is a risk of falling from the roof and electric shock, causing unnecessary property loss and casualties
