A split-level high-speed railway platform door with bottom drive

Abstract

The invention relates to the field of high-speed railway / intercity railway platform screen doors, in particular to a bottom-driven split-level high-speed railway platform door, which includes several movable door unit groups arranged continuously along the direction of the platform, and each movable door unit group includes a closing The first dodge door, the second dodge door, the third dodge door and the fourth dodge door are arranged in order in the state; In the second row; the driving devices of the first movable door and the third movable door are arranged at the bottom of the first row and are staggered up and down, and the driving devices of the second movable door and the fourth movable door are arranged at the bottom of the second row and are staggered up and down ; The first dodge door and the fourth dodge door are configured to be able to move 1 or 2 dodge door widths to the central position of the dodge door unit group where they are located under the drive of their driving mechanism; the second dodge door and the third dodge door are It is configured to be able to move to the left or right side by 1 dodge door width driven by its driving device.

Description

technical field [0001] The invention belongs to the field of high-speed railway / intercity railway platform screen doors, and in particular relates to a bottom-driven split-level high-speed railway platform door. Background technique [0002] The platform screen door system is set on the edge of the platform to isolate the passenger waiting area from the train operation area, and corresponds to the train door. It can control the opening and closing of sliding doors in multiple levels. Generally, there are full-height, half-height, airtight and Non-airtight, referred to as screen door or platform door. When the train arrives and departs, the screen door can be opened and closed automatically, and the driving space is mechanically isolated from the passenger waiting space, creating a safe and comfortable waiting environment for passengers. Because there are many types of high-speed rail trains, and many factors such as different door layout positions of different types of trai...

AI Technical Summary

Problems solved by technology

However, in this technical solution, since the left / right sliding stroke is fixed, and each sliding door only realizes the door opening action through one-way movement, the adaptability of this method to vehicle models is actually limited, and it cannot be adjusted according to different models. Adjust the door opening position. For example, when the train door is just in the overlapping area of ​​the left / right sliding door, this solution cannot realize the alignment door opening
