Transverse push type unlocking and anti-pinch device for gate

Abstract

The invention discloses a transverse push type unlocking and anti-pinch device for a gate. A mechanical portion comprises a transverse push touch plate (1), a lock body mechanism (2) and a lock cylinder transformation mechanism (5), wherein the lock body mechanism (2) is mechanically connected with a slidable door lock rod (6) by the lock cylinder transformation mechanism (5); an electrical portion comprises a touch plate electrical switch (3), an anti-pinch unlocking device controller (15), an electrical by-pass switch (14) and an alarm device (16) at the position of a driver's door; a switchsignal of the touch plate electrical switch (3) is transmitted to the anti-pinch unlocking device controller (15) via an electrical switch signal transmitting wire (12); then the signal is transmitted to a gate central control plate (13); and the gate central control plate (13) transmits the signal to the alarm device (16) at the position of the driver's door. When a passenger falls into a gap between a train door and a sliding door, the body of the passenger extrudes the device, then the lock of the sliding door can be unlocked, injury of the passenger is avoided, and a safe protection effect is achieved.

Description

technical field [0001] The invention relates to the technical field of rail transit platform doors, in particular to a horizontally pressing unlocking and anti-clamping device for platform doors. Background technique [0002] At present, due to the space gap between the subway train and the platform door, there have been repeated accidents in China, which pose a great threat to the personal safety of passengers. "Subway Design Code" (GB50157-2013) requires: "When a platform door is installed at a station, the clear distance between the sliding door body of the platform door and the contour line of the vehicle (without opening the door) should be adopted when the vehicle uses a sliding door. When the vehicle adopts built-in doors or externally hung doors, the At present, on the basis of meeting the requirements of the code, the domestic subway design minimizes the space gap between the train door and the sliding door to prevent passengers from falling in and causing person...
