[0036] Specifically, as shown in Figure 5 The rear side of the base 1 is fixedly connected with a limiting plate 8, the inner side of the limiting plate 8 is rotationally connected with a rotating block 9, the rear side of the rotating block 9 is bolted with a mounting plate 10, and the outer side of the mounting plate 10 is threadedly connected with a mounting piece 11.

[0037] In the embodiment, by arranging the fixed frame 6 and the laser ranging sensor 7, when the subway platform door pedal device is installed, the laser ranging sensor 7 is installed inside the fixed frame 6. During the operation of the train, the laser ranging sensor 7 emits a laser beam towards the direction of the train, and then the laser beam is reflected back after encountering the train. Then the sensor receives the reflected light signal, and calculates the distance between the sensor and the train according to the time difference between the laser emission and the reception, so as to monitor the relative position relationship between the train and the platform in real time, so as to ensure the accurate docking between the subsequent pedal body 403 and the train door pedal, effectively reducing the safety hazards caused by the gap or excessive height difference between the pedal and the train door pedal, and improving the safety and convenience of passengers getting on and off the train.
