Anti-pinch screen door for rail transit

Abstract

This application proposes an anti-pinch screen door for rail transit, which includes two sets of symmetrically arranged mounting posts, a shield body, a sliding door frame, a sliding door track and a sliding door; the two sets of sliding doors move toward each other on the corresponding sliding door track. Open or close; the distance between the screen door track and the rail transit train body is greater than a safety distance A, preferably, the safety distance A is 30cm; it is characterized in that: it also has a sweeping and closing device, and the sweeping and closing device includes a scissor mechanism, Gear drive mechanism; one of the two scissor handles at the driving end of the scissor mechanism is hinged to the ground, and the other can slide in the direction perpendicular to the sliding direction of the screen door to drive the driven scissor handles to open and close; the final driven scissor handle is equipped with a sweeper Arm; the gear drive mechanism includes a rack installed on the sliding door, an intermediate gear meshing with the rack, and a sweeping arm gear meshing with the intermediate gear. The sweeping arm gear is fixedly connected to the shear handle hinged to the ground and is coaxial with the hinge axis. Axis; the length of the scissor handle hinged to the ground is less than the value of the safety distance A.

Description

technical field [0001] The invention relates to a platform safety device for rail transit, in particular to a subway platform, in particular to an anti-pinch screen door for rail transit. Background technique [0002] The screen door refers to a device that completely isolates the car body from other spaces on the platform when passengers are getting on and off the train carriage. [0003] The screen door system generally includes a column, a shield body and a sliding door. The sliding door is generally a pair of sliding doors, which correspond to the doors of the train and are opened and closed almost simultaneously to prevent the running train from touching people on the platform. Keep it closed after leaving to prevent passengers on the platform from falling into the track. [0004] The civil design code of rail transit requires that there is a certain distance between the outer contour line of the train and the screen door body (generally not less than 30 cm). gap and ...
