Description

Technical Field

[0001] This utility model relates to the field of subway engineering technology, specifically to a structure for an anti-pinch detection subway platform screen door. Background Technology

[0002] Most subways are built by excavating underground tunnels and reinforcing them with concrete and other materials before laying tracks for the subway to run on. They are independent of surface traffic conditions and can quickly transport people between stations in a short time. To prevent passengers from falling onto the platform due to airflow when the subway enters the station, most subways choose to install platform screen doors on both sides of the platform.

[0003] This door consists of a door frame and movable door panels. The door panels are closed when the subway is not entering the station and open again after the subway has come to a complete stop. The sliding of the platform screen door lacks intelligent sensing. If a person or object gets caught in the door panel when it is closed, it will be difficult for it to open on its own, which is not only very dangerous, but also lacks the ability to open, close and lock automatically.

[0004] Now, a novel anti-pinch detection subway platform screen door structure is proposed to solve the above problems. Utility Model Content
