Size-adjustable platform-door threshold cover plate

Abstract

The invention provides a size-adjustable platform-door threshold cover plate which is mounted between a platform and a train door. The platform-door threshold cover plate structurally comprises a basic block I, a basic block II and a plurality of threshold cover plate widening bars. The section of the connector is basic block I is concave, the section of the connector of the basic block II is convex, the threshold cover plate widening bars are clamped between the two sections to splice the platform-door threshold cover plate, and the 10005mm standard value of the gap limit requirement of the train door and the edge of the platform is satisfied. The size-adjustable platform-door threshold cover plate has the advantages that the problem that that the gap between the train door and the edge of the platform is large due to construction errors is properly solved, the problem that the gap between the train door and the edge of the platform is larger than a safety standard is solved thoroughly, and safety of passengers getting on and off a train is guaranteed; the problem that the gap between the train door and the edge of the threshold cover plate is excessively large is solved, and danger caused by the fact that the feet of passengers step into the gap during operation is avoided.

Description

technical field [0001] The invention relates to a platform door sill cover plate with adjustable size. Background technique [0002] At present, the screen door / safety door system (hereinafter collectively referred to as "platform door") has become a must-have system equipment in the construction of urban rail transit projects. Almost all new urban rail, subway and light rail projects must be equipped with platform door systems. In the early construction of the urban rail project, there were no additional installations at the beginning, and now some are also adding platform door systems. Because it plays an important role in the operation safety of urban rail, platform environment comfort, energy saving and environmental protection. [0003] On the one hand, the sill cover of the platform door protects the switch control system below, and at the same time, it also has the function of supporting the screen door or safety door to ensure its normal opening and closing. Get on...

AI Technical Summary

Problems solved by technology

This will cause the gap between the platform door cover and the train door to vary due to different construction errors. The conditions of each station of each subway line are different, and the construction personnel and equipment are different, resulting in different construction errors. The gap between the edge and the train door also varies, with many stations having large gaps of more than 100 0 5 There are many standards for mm, and the situation is even more serious at curved stations. Passengers who get on and off the bus can easily step into the gap and cause danger. At present, there is no good remedial solution at home and abroad. The problem has been plaguing the operation and management departments of various places. Operation leaves great security risks

Some remedial measures are to install rubber strips on the edge of the platform, but it can only solve the error of 20-30mm, and the error cannot be solved no matter how large the error is, and the rubber strips are not firm and durable, so the effect is not ideal
