Platform screen door system

Abstract

A platform screen door system includes a fixed driving panel and at least one door leaf slidable relative to the fixed driving panel. Further included is a telescopic guide including a fixed guide mounted on the fixed driving panel, a moving guide mounted on the at least one door leaf, and a moving intermediate guide mounted on the fixed guide. Also included is a drive means for slidably moving the at least one door leaf from a closed position to an opened position wherein the at least one door leaf overlaps the fixed driving panel.

Description

technical field [0001] The present invention relates to a platform screen door or gate, and a mechanism for opening and closing said door or gate. Background technique [0002] Essentially the same design that had been in use since the beginning of the railway industry in the 19th century and became an effective solution to the problem of maximizing passenger boarding speeds, traditional railway stations consisted of raised platforms adjacent to the tracks. [0003] However, the basic platform configuration suffers from a number of well-known problems, such as passengers falling under the train, intentionally or accidentally, and litter from passengers' hands falling onto the tracks. Although accidents in which people fall under trains are uncommon, they can cause significant disruption to the rail network and be traumatic for everyone involved. The problem of litter on the tracks has also grown in recent years and can pose a serious health and safety risk to the subway or ...

Problems solved by technology

However, it is often difficult to refurbish the platforms with such a system, because it is expensive to dig out the tunnels from the platforms, and the tunnels themselves will accumulate dust

Some solutions house the mechanism in a box, but this approach suffers from the problem that the box is placed higher than the platform, creating a step that makes the system more difficult to use for wheelchair users

[0010] Another problem is that in some subway systems, the door spacing is relatively short, which allows passengers to board and disembark quickly, but when the doors or gates are open, when this short spacing corresponds to the required clearway (clearway) Combined conditions will result in the requirement that the equipment used to support and guide the sliding door in the closed position does not interfere with the sliding door or the area adjacent to the door when the door is in the open position

This problem is particularly acute because the loads that the sliding door has to resist must be reacted over the length of the support, which known head structures generally cannot provide due to space constraints
