Description

Technical Field

[0001] The utility model relates to the technical field of rail transportation, and more specifically to a rear sealing plate structure of a platform door. Background Art

[0002] Platform doors are commonly used on subway platforms, intercity platforms and train platforms. They can also be used in other similar platforms or similar engineering scenarios to keep the doors closed before the train stops and opens, isolating passengers on the platform and preventing them from falling off the platform and onto the tracks.

[0003] At present, the installation of the rear cover plate of the subway full-height platform door top box is generally carried out in the track area. Usually the rear cover plate is first transported to the track area, and multiple installation workers build scaffolding in the track area to install and lock the rear cover plate. The installation is relatively troublesome, and each time the track area is operated, guards must be set up at the front and rear of the vehicle for protection. If a rail vehicle passes temporarily, the scaffolding needs to be urgently dismantled to clear the track area, and the scaffolding needs to be re-erected after the rail vehicle passes, which poses a hidden danger to driving.
