Description

Technical Field

[0001] The present invention relates to the field of high-speed railway platform door structures, and in particular to a movable, telescopic and adjustable platform screen door system suitable for multiple types of trains. Background Art

[0002] High-speed rail stations are where high-speed trains stop. Passengers board and disembark at these stations. In addition to the high-speed train tracks, there are also high-speed rail platforms at these stations. To ensure safe entry and exit from high-speed trains, it's best to have a platform screen door system corresponding to the high-speed trains. This system separates the platform area from the track area. When a high-speed train arrives, the sliding platform screen doors slide open to allow passengers to board and disembark, then close again to create a protective area within the platform area, preventing passengers from accidentally falling onto the track area, which could lead to accidents. The vehicles running in high-speed railway stations are usually a mix of CRH3C 16 / 8-car formations, CRH380BL 16-car formations, CRH380A non-altitude cold 8-car formations, and CRH380A high-altitude cold 8-car formations. Since the door spacing of these vehicles is inconsistent, the traditional platform door system cannot adapt to high-speed trains of various models. There will also be situations where the platform doors (also known as platform doors) do not correspond to the doors of high-speed trains. In summary, due to the existence of many problems, there are currently few high-speed railway stations that install platform doors or platform doors. Those that do install platform doors can only adapt to a relatively single type of high-speed train. For subsequent additions to the model, all of them need to be dismantled and modified. After the addition of models, the structure changes greatly, and the construction is difficult, which affects the normal operation of the platform. Summary of the Invention

Both sides of the movable side box 2 are provided with sliding and retractable screen doors 4 and screen door drive devices 6, which respectively drive the retractable and retractable movement of the screen doors 4. The movable side boxes 2 and the structures driving the movable side boxes 2 are identical in the present invention, except for possible differences in their internal configurations. The screen door drive devices 6 and the extension panel retractable drive devices 5 are identical in the present invention. One side of the movable side box 2 of the movable and extendable screen door module defines an extension panel accommodating cavity corresponding to the retractable extension panel 3, while the other side of the movable side box 2 defines a screen door accommodating cavity corresponding to the screen door 4. Both sides of the movable side box 2 of the movable screen door module define screen door accommodating cavities corresponding to the screen door 4.

[0034] Two adjacent movable extendable screen door modules of the present invention share a telescopic extension plate 3. The telescopic extension plate 3 of the movable extendable screen door module is laterally provided with two telescopic driven rails 31. The two telescopic driven rails 31 are arranged in parallel vertically. In this way, the shared telescopic extension plate 3 can be stored in one of the movable extendable screen door modules.

The following is an example of a combination:

[0035] Since high-speed trains have two doors in each of the two adjacent carriages, the platform screen door system is composed of platform screen door units. Figure 7 The screen door component unit of a screen door system includes two sets of split screen door assemblies corresponding to two adjacent carriages. The screen door component unit includes four movable side boxes 2, wherein the screen doors 4 of two adjacent movable side boxes 2 in the three movable side boxes 2 form a split screen door assembly.

In this way, a platform screen door system suitable for multiple types of high-speed trains can be combined. Then, by adjusting the amount of retractable extension panels that are stored or unfolded in the movable side boxes 2, the size difference of the front and rear doors of the same carriage can be adjusted. At the same time, the platform screen door system can be moved as a whole on the sill track 1 through the side box moving drive device 7 of each movable side box 2 to adapt to the deviation of the parking position of the high-speed train. The platform screen door system of the present invention has strong structural replaceability and applicability, and can fully meet the needs of sliding doors (also known as platform screen doors) in high-speed railway platforms. When adding more models, it is only necessary to replace and install the corresponding components of the sliding door opening position and perform the arrangement. The corresponding telescopic device of the platform needs to be replaced with a sliding door, and the corresponding electrical components, such as DCU and motor, need to be added to realize the corresponding opening of the sliding door after the corresponding position is replaced.

Preferably, the top of the screen door 4 is a guide rail structure, and the guide wheel assembly 68 is a guide wheel assembly disposed on both sides of the top of the screen door 4.

[0040] The preferred side of each movable side box 2 of the present invention is provided with an advertising screen and / or a train carriage and a train guide indicator screen. The side box moving drive device 7 is a drive motor A, which is connected to the drive roller 71 through a gear transmission assembly.

[0041] To achieve intelligent control of the movable, telescopically adjustable platform screen door system, the present invention also includes a platform screen door control system 8, which includes a movable side box movement control module 81, a platform screen door switch synchronization control module 82, and an extension panel extension control module 83.
