The platform compensator comprises a platform installation frame and a gear rack assembly, a pedal A is arranged on a platform board, double-axis linearguide rails are correspondingly fixed to the left side and the right side of the platform installation frame, sliding blocks are mounted in the double-axis linear guide rails in a rolling mode, supporting frames are fixedly connected to the sliding blocks, a pedal B is fixedly connected between the left supporting frame and the right supporting frame, a motor, an unlocking device and a lock cylinder assembly are arranged at the bottom of the platform board, the unlocking device comprises a motor brake, a shifting fork, a lock dog mounting seat, a lock tongue, a fixing plate and a spring, thelock core assembly comprises a lock cylinder rotating disc and a lock disc, the lock disc is fixed to the fixing plate through a screw, the lock core turntable is rotatably mounted in the lock disc, and a reset indicating position and an unlock indicating position are arranged on the lock disc of the lock cylinder assembly. According to the platform compensator, the motor is locked or unlocked through the unlocking device, misoperation can be prevented, power of the motor is transmitted to the pedal B through the gear rack assembly and drives the pedal B to extend or retract, and operation isvery convenient.

Description

technical field [0001] The invention relates to a platform auxiliary device, in particular to a platform compensator. Background technique [0002] When the existing rail transit train stops at the platform, there is a large gap between the outer edge of the door and the platform. Passengers need to step over the gap when getting on and off the train, and there is a possibility of stepping on the gap and falling down. Therefore, the platform is equipped with a platform compensator to reduce the gap. Generally speaking, a telescopic platform compensator is used, that is, the pedal is usually hidden in the car body under the door. When the train stops, the pedal protrudes from the car body. , to fill the gap between the platform and the door. The installation of the platform compensator needs to occupy a certain amount of vehicle space. The existing telescopic platform compensator occupies the vehicle space below the floor at the door of the vehicle, and it is inconvenient to...

AI Technical Summary

Problems solved by technology

The installation of the platform compensator needs to occupy a certain amount of vehicle space. The existing telescopic platform compensator occupies the vehicle space below the floor at the door of the vehicle, and it is inconvenient to maintain after installation. The door must be fully opened before extending the pedal. When closing the door, the pedal must be retracted before closing the door. Passengers may enter and exit the train when the door is not fully opened or closed, so there are certain safety hazards
