Collision avoiding structure of safety footboard of rail transit platform

Abstract

The invention discloses a collision avoiding structure of a safety footboard of a rail transit platform. The structure comprises a movable push rod 511 and an L-shaped rotating bracket 901, wherein the movable push rod 511 is mounted at one end of a cross beam at the front end of a movable frame, and telescopically moves along the cross beam; the two ends of the bracket 901 are respectively in sliding connection with a fixed frame base and the movable push rod 511; the turning end of the bracket 901 is rotationally connected with a sliding frame; and the horizontal thrust of the movable rod 511 is converted to the inward tensile force on the sliding frame by the bracket 901. Through the collision avoiding structure, once the emergency that a train runs into the platform and the footboard does not retreat occurs, the head of the train collides with the movable push rod and generates a strong thrust, and the thrust is automatically converted to the inward tensile force of the sliding frame through the L-shaped rotating bracket. Therefore, the sliding frame and the footboard retreat back to the fixed frame base to prevent further collision between the train and the footboard. Thus, all possibilities of damaging the rail transit train or generating adverse effect on the operation of the train are prevented as far as possible.

Description

technical field [0001] The invention relates to the rail transit field, in particular to the rail transit safety assurance technology. Background technique [0002] In the process of rail transit construction, in order to ensure the safe running of trains, there is often a certain gap between the platform and the train body, which brings certain safety hazards to passengers. During the process of getting on and off the bus, passengers are likely to trip over the gap, or get their feet stuck in the gap due to stepping on the air. In order to solve this problem, some existing rail transit lines install fixed rubber pedals on the edge of the platform to reduce the gap between the platform and the train body. It is not easy to damage the car body. [0003] Yet prior art has following deficiency: [0004] First of all, although the gap between the platform and the car body is reduced, it still exists, and there are still potential safety hazards. For the disabled, infants, and...

AI Technical Summary

Problems solved by technology

[0004] First of all, although the gap between the platform and the car body is reduced, it still exists, and there are still potential safety hazards. This problem is particularly prominent for the disabled, infants, and women who wear high heels

[0005] Secondly, during the running of the train, friction and impact are likely to occur between the car body and the pedals, which accumulate over a long period of time and easily cause damage to the train

Moreover, the damage rate of platform pedals is relatively high, and the later maintenance costs are relatively high
