Embodiment Construction

[0025] The invention discloses a platform telescopic pedal, the telescopic part of the pedal is retracted into the fixed part of the pedal before the train stops, and the telescopic part is stretched out under the control of the signal after the train stops to fill the fixed pedal gap with the train. After the screen door is closed, the telescopic part retracts into the cavity of the fixed pedal. see figure 1 and figure 2 , which has a cuboid fixed pedal box 1 horizontally fixed on the platform. The fixed pedal box opens towards the side of the rail. The opening is provided with a movable pedal 2. The movable pedal is positioned at the inner side of the fixed pedal box and fixed horizontally. The rack 3 is driven by the drive assembly to push the movable pedal into or out of the fixed pedal box, and the drive assembly is controlled by the controller 23 . The rack 3 and the movable pedal 2 are vertically fixed, and the rack 3 promotes the movable pedal 2 to retract or stret...

Abstract

The invention discloses a platform extensible pedal which comprises a cuboid-shaped fixed pedal box (1) horizontally fixed on a platform. An opening is formed on one side, facing rails, of the fixed pedal box, a movable pedal (2) is arranged at the opening, a rack (3) is horizontally fixed on the inner side face, positioned inside the fixed pedal box, of the movable pedal and driven by a driving component to push the movable pedal to retract into or extend out of the fixed pedal box, and the driving component is controlled by a controller (23). Before a train draws up at a station, the movable pedal retracts to leave big space to the rails, quick passing of the train is facilitated, and friction and collision of the train and the platform are avoided; after the train draws up at the station and comes to a complete stop, the movable pedal extends out to enable a compartment of the train and the platform to be in seamless connection for the convenience of passengers to go in and out; a pressure sensor and a stopping device are mounted in the movable pedal, and the movable pedal does not retract when a person stands on, so that safety and reliability in use are realized.

Description

technical field [0001] The invention relates to a subway screen door step board, in particular to a retractable platform board. Background technique [0002] The congestion of ground vehicles is becoming more and more serious, and the subway has become the first choice for people to travel and an indispensable and important means of transportation. In order to ensure that the subway passes through the platform smoothly and prevent the train from colliding with the platform, a gap of 50mm-200mm is left between the train and the platform. But this gap brings inconvenience to the passengers in and out of the compartment, it is easy to cause the passenger's feet to get stuck in the gap and be injured, and it will also cause the trolley case with wheels to generate greater resistance and vibration when passing. Contents of the invention [0003] The present invention is to eliminate the gap between the train and the platform in the prior art, and proposes a retractable platfor...
