Description
Technical Field
The utility model belongs to the technical field of urban rail transit station platform door structure, especially relate to a clearance between platform door dodge gate structure, the platform door body and the train prevent pressing from both sides high platform door of tilting measure.
Background
With the rapid development of urban rail transit in China, a high platform door system is widely applied to the edge of a subway station platform to realize effective physical isolation between the subway station platform and a train, so that danger and interference of the train in and out of the station in the running process to passengers are avoided, and the safety of personnel is ensured. The mechanical structure of the high platform door mainly comprises a frame structure, a door body, a top box, a door machine and the like, wherein the door body comprises a movable door, an emergency door, an end door and a fixed door. The installation and arrangement scheme of the door body of the conventional high platform door is as follows: all door bodies are vertical to the platform surface, other doors except the end door are parallel to the train, and the door bodies are reliably and fixedly arranged with the civil structure of the station along the edge of the station and on the effective length of the station in the public area range. When the subway train enters the station and stops stably, the door and the movable door of the high platform door system are opened almost simultaneously, and passengers get on or off the station.
In order to ensure the running safety of the train, equipment, structures and the like on the platform must have a certain horizontal safety distance with the dynamic envelope curve of each part of the train. One side of the cross section of the existing subway train in China has a wider middle-lower part and a narrower middle-upper part, and is approximately in a bow shape. The conventional method for installing high platform doors is to determine the installation positions of the whole train of platform doors by taking the limit size of the widest part of a train as a reference; the door body forms a 'retaining wall' plane parallel to the train along the edge of the platform to separate the train from passengers waiting for the train; if the dimension of the plane from the widest position of the train meets the limit requirement, the dimension of the other narrow positions of the train from the platform door body is ensured to meet the limit requirement. The gap with a certain width exists between the platform door body and the static train body, the size of the gap value is the minimum value at the widest part of the train body profile because the train body profile is an irregular geometric surface rather than a unique value, other parts become larger along with the narrowing of the train body profile size, and the gap value is very large particularly at the top and the bottom of the train. Passengers are crowded when getting on or off the train in the peak period of subway operation, and thin and weak passengers are possibly extruded into the gap by people flow when getting on or off the train; in extreme cases, if the movable doors of the train door and the platform door are closed at the moment and passengers extruded into the gap are not found by a driver, the passengers clamped between the train and the high platform door body are inevitably seriously injured once the train is dispatched.
The current method for solving the problem in engineering is to detect whether a person is clamped between a train body and a high platform door body before the train is sent out by adopting a laser or infrared detection method, or to add an anti-climbing device on a movable door to prevent passengers from entering the gap. However, the laser or infrared detection device has no mature and reliable equipment at present, and false alarm often occurs, so that the normal operation of the subway train is influenced; the anti-climbing device has an unsatisfactory actual use effect. None of the above-mentioned devices is completely effective in solving the problem of man-in-the-middle accidents. Therefore, a simple, reliable and practical measure for protecting passengers and preventing people from being involved in accidents is urgently needed.
