Description

High-speed railway platform door based on dislocation formula structure

Technical Field

The utility model belongs to high-speed railway/intercity railway platform shield door field especially relates to a high-speed railway platform door based on dislocation formula structure.

Background

The platform screen door system is a continuous screen which is arranged at the edge of a platform, isolates a passenger waiting area from a train running area, corresponds to a train door, and can open and close a sliding door in a multi-stage control mode, and generally has the characteristics of full height, half height, sealing and non-sealing, and is called a screen door or a platform door for short. When the train arrives and departs, the shielding door can be automatically opened and closed, the driving space and the passenger waiting space are mechanically isolated, and a safe and comfortable waiting environment is created for the passengers.

In the operating environment of high-speed railways and inter-city railways, due to the fact that the train density is high, factors that trains passing through stations (without stopping stations) pass through the stations at high speed and the like can cause a series of aerodynamic problems, and therefore the safety of passengers and workers on the platforms is threatened, and particularly the situation of underground platforms is solved.

In the design and construction of part of intercity railways, in order to embody the characteristic of fast forward and fast out of the intercity railways and save the engineering investment, the intercity railways also adopt a platform waiting mode similar to a subway, the potential safety hazard of platform waiting is increased, and a platform door device is necessary to be arranged on the edge of the platform to ensure the safety of passengers and the operation safety. However, in high-speed trains and inter-city trains in China, due to the mapping that transportation lines are widely distributed, the distance in operation is long, and the like, the on-line operation vehicles entering the station in the same platform have the condition of various types of vehicles, so platform doors used in the environment face the requirement of adapting to the stop of trains of various types.

In the prior art, for example, chinese patent publication No. CN104176067A entitled "platform safety door adapted to all train models" discloses a platform safety door structure, in which two sets of sliding door assemblies are installed on the same column in a staggered manner two by two, and the door structure includes a left sliding door and a right sliding door with opposite sliding directions, and after a train arrives at a station and stops stably, the left sliding door of the door structure slides and then overlaps with the right sliding door of the door structure adjacent to the left; after the right sliding door of the door body structure slides, the right sliding door of the door body structure is overlapped with the left sliding door of the adjacent door body structure on the right, so that the parking door structure is suitable for parking door positions of different vehicle types. However, in this technical solution, since the stroke of the left/right sliding is fixed, and each sliding door only moves in one direction to achieve the door opening action, the adaptability of this method to vehicle types still has limitations in practice, and the door opening position cannot be adjusted according to different vehicle types, for example, when the train stops at a position where the doors of the train are just located in the overlapping area of the left/right sliding doors, the alignment door opening cannot be achieved by this solution.
