Door clearance compensator, door clearance compensator control system and method, and rail vehicle

Abstract

The invention relates to the field of rail vehicle clearance compensation, and provides a door clearance compensator, a door clearance compensator control system and method, and a rail vehicle. The door clearance compensator control system comprises: an air cylinder used for driving a pedal body to horizontally stretch out and draw back along the bottom face of a floor body, wherein the air cylinder comprises a cylinder body and a piston stretching out and drawing back along the cylinder body, and an extending air inlet and a retracting air inlet are formed in the cylinder body and connected with air pipelines respectively; an inductive switch arranged on the air cylinder and used for inducting the position of the piston; and a controller used for controlling the extending air inlet or theretracting air inlet to intake air according to the position, detected by the inductive switch, of the piston so as to control the piston to extend to a designated position or retract to the designated position. The door clearance compensator can solve the problems that an existing door clearance compensator of a pneumatic structure is of a turnover structure, large in occupied space, complex instructure and low in reliability, the telescopic stroke of a pedal cannot be controlled, and the telescopic distance of a pedal is fixed and cannot be adjusted.

Description

technical field [0001] The invention relates to the technical field of rail vehicle gap compensation, in particular to a door gap compensator, a door gap compensator control system, a method and a rail vehicle. Background technique [0002] The door gap compensator, as the name suggests, is used to compensate the gap between the door and the platform. After parking, the pedal of the door gap compensator extends toward the platform, which is convenient for passengers to get on and off; Retract away from the direction of the platform so as not to affect the normal driving of the vehicle. [0003] However, the existing door gap compensator has the following disadvantages: (1) The door gap compensator of the existing pneumatic structure adopts a flip structure, which occupies a large space, has a complex structure, and has low reliability; [0004] (2) The existing pneumatic push structure cannot realize the control of the pedal telescopic stroke, and the pedal telescopic dista...

AI Technical Summary

Problems solved by technology

For this reason, the present invention proposes a door gap compensator control system, which solves the problem that the door gap compensator of the existing pneumatic structure adopts a flip structure, which takes up a large space, has a complex structure, and has low reliability, and cannot realize the control of the pedal telescopic stroke. , the problem that the pedal telescoping distance is fixed and not adjustable
