Automatic anti-pinch damper of platform screen door

Abstract

The invention discloses an automatic anti-pinch damper of a platform screen door. The automatic anti-pinch damper is arranged on the ground between the platform screen door and a compartment of a train and comprises an anti-pinch damper, a limiting shaft sleeve, a rotating shaft, a fixing plate, an opening push block and a closing push block. Three bumps at a side edge of the anti-pinch damper penetrate through three notches of the limiting shaft sleeve to be fixed onto the rotating shaft, the limiting shaft sleeve is sleeved on the outside of the rotating shaft and is fixedly connected onto the fixing plate, and the rotation angular range of the anti-pinch damper and the rotation angular range of the rotating shaft are limited by widths of openings of the three notches. The opening push block and the closing push block are respectively fixed to the lower end of the left side edge and the lower end of the right side edge of a single-leaf movable door, move left and right along with opening and closing of the movable door, and push the anti-pinch damper to rotate around the rotating shaft. After the movable door is opened completely, the anti-pinch damper is pushed to be perpendicular to a body of the platform screen door and is limited by the lifting shaft sleeve to be fixed, so that passengers are prevented from entering a gap between the compartment of the train and the platform screen door. Accordingly, the safety performance of a platform screen door system is improved, and the automatic anti-pinch damper has popularization and application prospects.

Description

technical field [0001] The invention relates to a protective device for a platform of an urban rail transit subway station, in particular to an automatic baffle arranged between a platform screen door and a train. Background technique [0002] With the rapid development of my country's urban rail transit, the platform screen door system of subway stations has been widely used. [0003] The shielded door system mainly includes a shielded door composed of a fixed door and a movable door and its control device. The screen door is installed on the edge of the platform to completely isolate the platform from the driving track, forming a safe isolation space between the public area of ​​the platform and the driving track. The fixed door of the screen door is fixed on the platform, forming an isolation space between the public area and the driving track. The isolation space makes the equipment and structures on the platform have a certain safety distance from the train. The fixed...

Problems solved by technology

[0005] Aiming at the problem that the platform screen door system of the subway station cannot completely solve the problem of pinching accidents, the present invention introduces a screen door anti-pinch automatic barrier device, the purpose of which is to set a barrier on the platform ground between the screen door and the train carriage. The plate rotates around the axis under the push of the movable door of the screen door, and prevents passengers from entering the gap between the train and the door body of the screen door when the movable door is closed, effectively preventing the occurrence of pinching accidents and protecting the safety of passengers
