Description
Technical Field
The invention relates to the technical field of rail transit platform doors, in particular to an adjustable anti-treading empty plate for a platform door.
Background
The anti-empty-stepping plate is generally applied to urban rail transit platform doors, particularly subway platform doors. The anti-treading plate should have elasticity and is generally made of rubber. The anti-empty-pedal plate is installed on the side of the threshold rail of the subway platform door. When a subway train arrives at a station and a platform door is opened, passengers getting on and off need to pass through a gap between a platform door threshold and a train door, and at the moment, the passengers have the risk of falling into the gap. The anti-empty-tread plate extends from the side of the threshold rail of the subway platform door to the train, so that the gap is reduced, and the risk that passengers fall into the gap is reduced.
The existing fixed type anti-empty-stepping plate is provided with an adhesive tape fixed on the side of a threshold rail, and the adhesive tape is not movable. In order to prevent the rubber strips from scraping the running train, the rubber strips cannot completely fill the gaps, so that the gaps between the doorsill and the train can only be reduced as much as possible no matter how the materials, the structures and the installation mode of the existing anti-treading empty plate are improved, the gaps cannot be completely filled in principle, and the risk that passengers tread empty to fall into the gaps cannot be completely eliminated.
As mentioned above, the presence of a gap leads to the following risks: firstly, the gap is possibly too large, so that passengers can inadvertently step in the air in the process of getting on or off the vehicle and fall into the gap; secondly, the gap is possibly too small, so that the platform threshold is scratched by the side surface when the train passes through the station, and the platform threshold and the train are damaged. In addition, once a passenger carelessly falls into the gap, the existing fixed type pedal-free plate cannot be quickly disassembled, is not beneficial to rescuing the trapped passenger, generally needs to be destructively disassembled, and causes difficulty in repairing after an accident.
