Safety pedal for rail transportation platform

Abstract

The invention discloses a safety pedal for a rail transportation platform, which comprises a fixed frame base, a sliding frame and a pedal part. The pedal part is fixedly arranged at the front end of the sliding frame; the sliding frame is connected with roller-type sliding block sets on the fixed frame base in an insertion manner by sliding rails so as to implement telescopic motion. By the telescopic safety pedal, the problem of the potential safety hazard brought to passengers by a gap between the platform and a train door of a train can be effectively solved and obstruction cannot be caused for the train in the running process. Moreover, by coaxial three points (more points also can be provided), the safety pedal is synchronously controlled to extend and retract and the sliding frame of the safety pedal can be subjected to multipoint stressing in the telescoping process so as to enable different positions of the sliding frame to be uniformly stressed in the transverse direction, thereby enabling the safety pedal to be difficult to deform in the long-term running process of the train, prolonging the service life of the safety pedal and ensuring the stability and safety of the safety pedal in the operation process.

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
