Description

Technical Field

[0001] This utility model belongs to the field of train equipment technology, and in particular relates to a transition device for the gap between a train and a platform. Background Technology

[0002] During tram operation, a certain gap is usually left between the edge of the tram platform and the tram car to ensure that the tram can smoothly enter and exit the platform. However, when passengers enter the tram from the platform, their belongings may fall into the gap, and sometimes children's feet may get stuck. This not only causes loss of belongings and poses a risk to personal safety, but may also affect the normal operation of the tram, and also increases the difficulty and operational risks for staff to clean up. Currently, simple gap-filling measures, such as laying rubber strips, are used for some platforms with large gaps. However, these methods often have problems such as insecure fixing, easy wear and tear, and inability to be flexibly adjusted according to the tram's entry and exit status. When a tram enters the station, the fixed filling structure may collide with the train carriage, causing component damage and affecting the sealing effect. Utility Model Content

Attached Figure Description

[0012] To more clearly illustrate the technical solutions of the embodiments of this utility model, the drawings used in the description of the embodiments will be briefly introduced below. Obviously, the drawings described below are some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the following description is provided in conjunction with the appendix. Figures 1-4 The present invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0015] This utility model discloses a transition device for the gap between a train and a platform, including a mounting frame 1 placed on the side wall of the platform. A sealing plate 2 is slidably mounted on the mounting frame 1 via a sliding rod 24. The sealing plate 2 includes a plate body 21, and a connecting groove 23 is formed on one end of the plate body 21. The sliding rod 24 is placed in the connecting groove 23. A rubber pad 6 is fitted to the side of the sealing plate 2 closest to the outer carriage. Two sliding rods 24 are provided, extending vertically and placed on the side walls at both ends of the mounting frame 1. The mounting frame 1 is fixed to the side wall of the outer platform by fixing screws 10 passing through through holes 9 on the mounting frame.

[0016] The upper surface of the plate 21 is provided with a sliding groove 22, which is inclined on the surface of the plate 21. A support rod 3 is vertically arranged in the sliding groove 22, and the upper end of the support rod 3 is connected to the bottom of the external platform door. The support rod 3 is located at the opening end of the external platform door. When the platform door moves the support rod 3, the sliding of the support rod 3 in the sliding groove 22 is converted into the linear motion of the plate 21 on the sliding rod 24. This allows the plate 21 to automatically extend and block the gap when the platform door opens and automatically reset when the platform door closes, without the need for additional power. A rubber pad 6 is fitted to the side of the plate 21 closest to the external carriage. The rubber pad 6 can fit against the side wall of the external subway carriage. Its elasticity can buffer the impact force of the collision between the plate 21 and the train carriage when the plate 21 extends and comes into contact with the carriage, avoiding damage or scratches to the carriage caused by direct collision between the metal plate 21 and the carriage.

[0017] Preferably, the sliding groove 22 is a through groove, extending from the upper end face of the plate 21 to the lower end face of the plate 21. This prevents debris such as stones from remaining in the sliding groove 22, thus avoiding interference with the sliding of the support rod 3 within the sliding groove 22. A rubber sheet 7 is provided on the upper surface of the plate 21, and a corresponding cut 8 is provided on the rubber sheet at the location of the sliding groove 22. Alternatively, the rubber sheet 7 can be placed only above the sliding groove 22, with the support rod 3 entering the sliding groove 22 through the cut 8.

[0018] In this embodiment, the connecting groove 23 extends from the side of the plate 21 into the plate body, and the end of the sliding rod 24 is T-shaped and extends into the connecting groove 23. A retaining ring 4 for limiting the position is also provided between the sliding rod 24 and the connecting groove 23. The retaining ring 4 is threadedly connected to the inner wall of the connecting groove 23 and is located at the open end of the connecting groove 23. The retaining ring 4 can prevent the sliding rod 24 from detaching from the plate 21. When it is necessary to remove the plate 21 for maintenance, the retaining ring 4 can be unscrewed to release the obstruction of the limiting block 5, and then the plate 21 can be directly removed from the sliding rod 24.

[0019] The sliding groove 22 is inclined from the near end of the opening end of the external platform door to the far end. That is, when the door is opened, it will drive the plate 21 to extend, and when the door is closed, it will drive the plate 21 to retract. The specific inclination angle and length of the sliding groove 22 are calculated and determined based on the opening and closing stroke of the platform door and the required extension distance of the plate 21. Generally, the length of the sliding groove is equal to the opening and closing stroke of the platform door, and the inclination angle is equal to the required extension distance.

[0020] Furthermore, the support rod 3 includes a rod body 31 detachably connected to the slide rail 32. The slide rail 32 is placed at the bottom of the external platform door. The rod body 31 is L-shaped, with its upper end fixed to the slide rail 32 by a bolt 34 passing through a threaded hole 33 on the rod body 31. The other end is placed vertically downward in the sliding groove.

[0021] When there are two lateral sliding platform doors on the platform, this device is installed under both platform doors, and the sliding grooves 22 on the two sealing plates 2 are mirror images of each other.

[0022] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0023] There are many specific application examples of this utility model. The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of this utility model, and these improvements should also be considered within the protection scope of this utility model.
