Description
Technical Field
The invention relates to the technical field of rail transit platform doors, in particular to a transverse pressing type unlocking anti-pinch device for a platform door.
Background
At present, the space gap between the subway train and the platform door frequently occurs in China, and the personal safety of passengers is threatened greatly. Subway design Specification (GB 50157-2013) requires: when the station is provided with the platform door, the clearance between the sliding door body of the platform door and the contour line of the vehicle (without opening the door) is adopted when the vehicle adopts the sliding plug doorWhen the vehicle adopts the built-in door or the externally hung door, the vehicle should adopt +.>The current domestic subway design is based on meeting the standard requirement, and space gap between the train door and the sliding door is reduced as much as possible, so that passengers are prevented from falling into the subway to cause personal injury.
The space gap between the platform door sliding door and the train door is composed of two parts, wherein the first part is the gap between the sliding door and the vehicle dynamic envelope, and the second part is the gap between the vehicle dynamic envelope and the vehicle static contour.
The traditional space gap anti-pinch method between the subway train and the sliding door mainly comprises the following 5 steps:
(1) the platform door installation limit is designed to be as close to the center line of the track as possible according to the standard requirements;
the method reduces the space gap between the train door and the sliding door as much as possible according to the standard requirement, but is limited by the dynamic envelope of the vehicle, the gap of the first part can only be reduced, but the gap of the second part can not be reduced, the gap between the train door and the sliding door is still large due to the fact that the gap of the second part is added with the space of the glass surface of the rail side sliding door and the thickness dimension of the door frame, and the risk of the passengers squeezing in exists.
(2) The side edge of the lower part of the sliding door is provided with an anti-pinch baffle;
the present method can only reduce the gap of the first portion and cannot reduce the gap of the second portion. And when the sliding door is closed and locked firstly, and then passengers fall into the gap to lock the train door, the anti-clamping effect cannot be achieved, and the situation safety accident occurs in a certain city, so that the protection scope is limited.
(3) Setting a laser or infrared electrical detection device;
the method is provided with a laser or infrared electric detection device to perform correlation detection on the sliding door area, and if passengers enter the detection area, an alarm is given, so that the driver is prevented from missing dangers and getting off. However, according to the domestic actual operation condition reaction, the electrical detection device is interfered by the factors such as an ambient light source, insects, dust and the like, so that the problem of high false alarm rate exists, and the normal operation of the train is affected.
(4) Manual unlocking device of the sliding door at the track side;
the method is to arrange an emergency manual unlocking device on the sliding door, the device is tightly attached to the side of the sliding door frame, and the sliding door lock is unlocked after the sliding door is manually separated from the two sides. Such locks can only be used effectively if the person is facing the handle of the unlocking device and there is room for operation. When a passenger is clamped between the train door and the sliding door, the passenger cannot be unlocked without an operation space, and the automatic unlocking function cannot be achieved.
(5) The tail of the vehicle is provided with a driver lookout lamp band;
according to the method, a lookout light band is arranged at the tail of the train, and a driver at the head of the train judges whether passengers drop between the train door and the sliding door by looking at whether the tail light band is blocked. The method is only applicable to straight-line stations or large-curve stations of which part does not influence lookout and is not applicable to large-curve stations of which the tail cannot be seen from the head.
