Problems solved by technology

[0003] However, the current existing door gap compensator has the following disadvantages: (1) The pedal body of the current door gap compensator is made of stainless steel, which is heavy in weight. produce permanent deformation
[0004] (2) Anti-slip materials are generally laid on the upper surface of the existing pedals. With the extension of the running time, the anti-slip materials are easy to fall off, reducing the anti-slip coefficient. The subsequent laying of anti-slip materials increases the weight of the door gap compensator, which is not conducive to lightweight design
[0005] (3) The stainless steel pedal structure currently used has a thicker installation part, and welding is generally used to increase the patch plate, but it is not easy to control the welding deformation, the construction is difficult and the cost is high

Abstract

The invention relates to the field of rail vehicle gap compensation, and provides a pedal profile structure of a door gap compensator, a door gap compensator and a rail vehicle. The door gap compensator pedal profile structure includes a pedal body, the pedal body includes a mounting section and a stepping section arranged in sequence from the back to the front, the front end of the stepping section is configured with a reinforcing section extending vertically downwards, the stepping section The upper surface of the section is formed with anti-slip lines; the thickness of the installation section is greater than that of the stepping section. The pedal body of the present invention is not easily deformed, ensures the reliability of the pedal, increases the anti-skid coefficient, effectively prevents passengers from slipping, and reduces the weight of the pedal while ensuring the installation strength, thereby realizing light weight.

Description

Technical field[0001]The present invention relates to the field of rail vehicle gap compensation techniques, and more particularly to gate space gap compensator pedal profile structures, gate gap compensators, and rail vehicles.Background technique[0002]Door gap compensator, as the name suggests, is used to compensate the gap between the door and the platform. After the parking, the pedal of the door gap compensator extends to the platform, facilitating the passenger to get off; the pedal to the shuttle door gap compensator Keep away from the direction of the platform to do not affect the normal driving of the vehicle.[0003]However, the existing door gap compensator has the following disadvantages: (1) The current gate gap compensator pedal main body uses stainless steel material, weight, the position of passengers is generally at the front edge of the pedal, the duration is running Produce permanent deformation.[0004](2) The existing pedal is generally laying anti-slip material. As...
