Safety pedal of rail traffic platform

Abstract

The invention discloses a safety pedal of a rail traffic platform. The safety pedal comprises a fixed frame base, a sliding frame and a pedal piece. The pedal piece is fixed to the front end of the sliding frame. The sliding frame is arranged in the fixed frame base and connected with the fixed frame base in a sliding mode. The sliding frame is guided by a guide rail and a guide device to horizontally stretch out of and retract back to the fixed frame base. A drive motor is fixed to the fixed frame base. A rack is fixed to the sliding frame and driven by the drive motor to push the sliding frame to stretch out of or retract back to the fixed frame base. By means of the safety pedal, the potential safety hazards, caused by the gap between the platform and a door of a train, to passengers can be effectively avoided, and interference to the running train can be avoided. Moreover, the stretching and retracting amplitude of the safety pedal can be adjusted, and the requirements of environments with variable gap widths of arc platforms, multi-vehicle platforms and the like are met. In addition, the failure rate of a transmission system can be effectively reduced through a rack gear mode, and the stability and safety of the pedal in the operating process are guaranteed.

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
