Platform screen door protection device

Abstract

The invention provides a platform screen door protection device. A multi-section sliding door is arranged on one side of a fixing side box; the width of the multi-section sliding door is greater thanthe width of a train door; the multi-section sliding door comprises at least two subsidiary sliding doors; one of the subsidiary sliding doors at one end of the multi-section sliding door is slidablyconnected to the fixing side box along a guide rail device; every two adjacent subsidiary sliding doors are slidably connected to each other along the guide rail device; an extension and retraction member of a driving device is fixedly connected to another one of the subsidiary sliding doors at the other end of the multi-section sliding door; a driving source of the driving device drives the extension and retraction member to extend or retract along the direction parallel to tracks; and an extension and retraction controller of the driving device controls the extension and retraction range ofthe extension and retraction member. Therefore, when the type of a stopped train is different or when the train deviates from the stopping position, the opening of the multi-section sliding door can be flexibly adjusted by setting the extension and retraction range, so as to ensure that passengers can get on or off the train smoothly, to minimize the range which a screen door protection system cannot protect, and to ensure the safety of the passengers when the passengers get on or off the train as much as possible.

Description

technical field [0001] The invention relates to the technical field of safety doors, and more particularly, to a safety door protection device for a platform. Background technique [0002] With the formation of my country's high-speed railway network, inter-city railway and urban rail transit, and the continuous improvement of railway technology innovation level, platform safety protection has become one of the hot spots. As a key equipment for platform safety protection, the platform safety door protection system has a very broad market. prospect. [0003] The existing safety door protection system is usually designed as a sliding door with a smaller fixed width, and the width of the sliding door just corresponds to the width of the listed car door, so as to be applicable to a certain fixed vehicle type; Features and the problem of low parking precision of railways and rail transit.

Problems solved by technology

[0003] The existing safety door protection system is usually designed as a sliding door with a smaller fixed width, and the width of the sliding door just corresponds to the width of the listed car door, so as to be applicable to a certain fixed vehicle type; Features and the problem of low parking precision of railways and rail transit. The safety door protection system suitable for a certain fixed vehicle type is not suitable for these platforms with many parking vehicles or low parking precision, which may cause passengers to be unable to get on and off normally. Appear; by increasing the width of the sliding door, even when the parked car models are different or the parking position is deviated, the safety door protection system with a sliding door with a larger width can still ensure that passengers can get on and off the car smoothly when the sliding door is fully opened

[0004] However, by increasing the width of the sliding door, when passengers get on and off the train, when the safety door protection system fully opens the sliding door, since the width of the sliding door is larger than the width of the train door, there will be a section that the safety door protection system cannot protect, which may Safety hazards for passengers
