Platform sliding door system

Abstract

The embodiment of the invention discloses a platform sliding door system which comprises a plurality of single-row sliding door sets horizontally arranged at the edge of a platform side by side from outside to inside, each single-row sliding door set comprises at least one single-guide-rail sliding door unit, and each single-guide-rail sliding door unit comprises a guide rail, a sliding door body and a driving transmission mechanism. The sliding door body is installed on the guide rail in a sliding mode through a sliding block so as to move along the guide rail, the driving transmission mechanism comprises a motor, a driven wheel and a driving wheel connected with the motor, the driving wheel and the driven wheel are in transmission connection through a transmission belt and arranged at the two ends of the guide rail respectively, one end of the transmission belt is connected with the sliding door body, and the other end of the transmission belt is connected with the sliding door body after winding the driving wheel and the driven wheel. According to the platform sliding door system, the multiple single-row sliding door sets are arranged at the edge of the platform side by side from outside to inside, the sliding door bodies in the front row and the rear row can move by different distances so that the platform door can be opened and closed, the structure is simple, and the problem that the positions of the doors cannot correspond is effectively solved.

Description

technical field [0001] The invention relates to the technical field of platform doors, in particular to a platform sliding door system. Background technique [0002] The platform door is installed on the edge of the platform near the side of the driving passage to separate passengers from the vehicles. The platform door should be equipped with an electric sliding door mechanism to control the opening and closing of the platform door. The door body controlled by the electric sliding door mechanism is called a sliding door. The sliding door corresponds to the position of the door when the car is parked. The sliding doors are filled by fixed doors that cannot move, and together form the platform door that closes the entire platform. [0003] The electric sliding door mechanism of the existing platform door can only make the sliding door do reciprocating opening and closing movement within a certain sliding door range, so that the opening position of the platform door is limited...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a platform sliding door system so that the sliding door body can arbitrarily control the sliding door body to move in various distances according to the door positions corresponding to different vehicle models to realize opening and closing, effectively solving the problem of multi-vehicle types. When the trains run mixedly, the door positions and numbers of the trains that stop on the platform are not uniform, so the door positions cannot be matched
