Description

Technical Field

[0001] This utility model relates to the field of high-speed rail technology, specifically to a movable retaining wall for high-speed rail platform doors. Background Technology

[0002] Platform screen doors (PSM) are installed along the edges of urban rail transit stations. They serve as a continuous barrier separating passenger waiting areas from train operating areas, corresponding to train doors, and capable of multi-level controlled opening and closing of sliding doors. When trains arrive and depart, the PSM doors automatically open and close, mechanically separating the operating space from the passenger waiting space, creating a safe and comfortable waiting environment for passengers, while also providing passageways for boarding and alighting.

[0003] However, in the context of multi-level rail transit integration, due to the large number of train models and the different door layouts of different models, the platform doors cannot be aligned with the doors of different train models, which poses certain safety hazards. Utility Model Content

[0024] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0025] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0026] Please see Figures 1-3 This utility model provides a movable barrier for high-speed railway platform doors, comprising: a shielding mechanism 1, a guide mechanism 2 connected to the shielding mechanism 1, and a transmission mechanism 3 connected to the shielding mechanism 1 and the guide mechanism 2.

[0027] In some embodiments, the shielding mechanism 1 is a part for forming a movable partition on the platform, which includes: a sliding barrier 11 and a support assembly 12 connected to the sliding barrier 11. The sliding barrier 11 is the main structure of the shielding mechanism 1. It is a square hollow structure and has a certain rigidity, which can protect the internal components of the sliding barrier 11 and prevent mechanical collisions and other damage to the internal structure.

[0028] Furthermore, the support assembly 12 is used to support the sliding barrier wall 11. In some embodiments, the support assembly 12 includes: a second roller 121, a support frame 122, and a third roller 123 disposed at the bottom of the support frame 122. The second roller 121 is disposed at the bottom of the sliding barrier wall 11, the support frame 122 is connected to the side of the sliding barrier wall 11 near the train, and the third roller 123 is connected to the bottom of the support 122. The above structure enables the support assembly 12 to support the sliding barrier wall 11 on the one hand, and to allow the sliding barrier wall 11 to be in a sliding state on the other hand.

[0029] In some more preferred embodiments, the support component 12 further includes: a guide wheel 124 and a guide rail 125 adapted to the guide wheel 124. The guide wheel 124 is located at the bottom of the sliding barrier 11 and has a concave structure in the middle. It is adapted to the guide rail 125 and can move along the setting direction of the guide rail 125. On the other hand, the concave part of the guide wheel 124 abuts against the guide rail 125, and the guide rail 125 can limit the guide wheel 124, thereby limiting the shielding mechanism 1 and preventing the wind pressure generated when the train enters or leaves the station from causing the shielding mechanism 1 to move.

[0030] In some embodiments, the guide mechanism 2 is a part for guiding the movement of the shielding mechanism 1, including: a guide groove 21, a slide rail 22 disposed in the guide groove 21, and a slider 23 slidably connected to the slide rail 22. In some embodiments, the guide groove 21 is opened in the platform to accommodate the guide mechanism 2. For example, the guide groove 21 can be set parallel to the train direction. The slide rail 22 is disposed in the guide groove 21 and slidably connected to the slide rail 22. The slider 23 moves on the slide rail 22, thereby guiding the shielding mechanism 1 to move along the direction set by the slide rail 22. The specific guiding process will be further described below.

[0031] In some embodiments, the transmission mechanism 3 is connected to the shielding mechanism 1 and the guide mechanism 2, and is used to drive the shielding mechanism 1 to move along the direction set by the guide mechanism 2. It includes: a rack 31, a gear 32 adapted to the rack 31, and a motor 33 connected to the gear 32.

[0032] In some embodiments, the slide rail 22 has a structure with a concave center and convex sides. The rack 31 is located in the concave part of the slide rail 22. The slider 23 has a structure with concave sides. The concave part of the slider 23 is movably connected to the convex part of the slide rail 22. The motor 33 and the gear 32 are located at the bottom of the slider 23. The gear 32 meshes with the rack 31, thereby driving the gear 32 to rotate using the motor 33. The gear 32 rotates on the rack 31, thereby realizing the movement of the slider 23 on the slide rail 22.

[0033] In some embodiments, the transmission mechanism 3 further includes: a first magnet 34, a second magnet 35 adapted to the first magnet 34, and a step plate 36 located between the first magnet 34 and the second magnet 35. The first magnet 34 is disposed on the slider 23, and the second magnet 35 is disposed on the support assembly 12. By utilizing the mutual attraction between the first magnet 34 and the second magnet 35, on the one hand, when the slider 23 moves, the transmission support assembly 12 moves with the slider 23, thereby realizing the process of using the transmission mechanism 3 to drive the shielding mechanism 1 to move along the direction set by the guide mechanism 2. On the other hand, it can also tighten the sliding barrier 11 to prevent the wind pressure generated when the train enters or leaves the station from causing the shielding mechanism 1 to move.

[0034] Furthermore, the step plate 36 is provided on the guide groove 21 to close the guide groove 21. On the one hand, it assists the driver and passengers in passing through, and on the other hand, it can prevent dust and other debris from entering the interior of the guide groove 21 and hindering the operation of the mobile platform door.

[0035] In some embodiments, the transmission mechanism 3 drives the shielding mechanism 1 to move along the direction set by the guide mechanism 2. By moving the shielding mechanism 1, after any train model stops, the exit of the movable barrier can be guaranteed to face the train door, so as to facilitate passengers to get on and off the train, thereby enhancing practicality.

[0036] Finally, it should be noted that the embodiments disclosed in this utility model are merely preferred embodiments of this utility model and are only used to illustrate the technical solutions of this utility model, not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of this utility model.
