Description

Technical Field

[0001] This utility model relates to the field of wheel stoppers, and in particular to a new type of railway wheel stopper. Background Technology

[0002] A wheel stop is a device used to prevent the wheels of railway vehicles from rolling. It is typically installed on the rails or near the wheels of the vehicle. It generates friction through contact with the wheel or rail, thus preventing the wheel from rotating and keeping the vehicle stationary. Its main purpose is to prevent slippage and braking of railway vehicles when they are stopped, ensuring the safety of the vehicle during parking and preventing accidental rolling due to various reasons. Existing modern railway wheel stops are inconvenient to replace friction plates that gradually lose effectiveness due to wear, resulting in high maintenance costs; furthermore, the spacing cannot be manually adjusted according to the width of the rails, lacking versatility and flexibility.

One end of the bidirectional lead screw passes through the cavity and is fixedly connected to a rotating block. The external thread of the bidirectional lead screw is connected to an active block.

[0008] As a further description of the above technical solution:

[0009] The adjustable fixing assembly also includes a driven plate, one end of which is fixedly connected to the outside of the driving block, and the other end of which is fixedly connected to a guide plate. A guide groove is provided at the bottom of the cavity, and a clamping plate is fixedly connected to one end of the guide plate through the guide groove.

[0010] As a further description of the above technical solution:

[0011] A positioning block is fixedly connected to the bottom of the wheel stop body, and the positioning block is located inside the clamping plate.

[0012] As a further description of the above technical solution:

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figures 1-4 The present invention provides an embodiment of a new type of railway wheel stop, comprising a wheel stop body 1 and a friction plate 2. An adjustable fixing component 9 for improving versatility and flexibility is provided inside the wheel stop body 1, and an installation component 3 for reducing maintenance costs is provided between the wheel stop body 1 and the friction plate 2.

[0027] The mounting component 3 includes a mounting block 4, which is fixedly connected to the outer side of the friction plate 2. The inner side of the wheel stop body 1 is provided with a mounting groove 5, and the mounting block 4 slides inside the mounting groove 5. Both the wheel stop body 1 and the mounting block 4 have through holes 6, and a screw 7 is slidably connected inside the through hole 6. One end of the screw 7 is externally threaded with a nut 8.

[0028] The adjustable fixing assembly 9 includes a bidirectional lead screw 10. A cavity 11 is provided inside the wheel stop body 1. Both ends of the bidirectional lead screw 10 rotate inside the cavity 11. One end of the bidirectional lead screw 10 passes through the cavity 11 and is fixedly connected to a rotating block 12. An active block 13 is threadedly connected to the outside of the bidirectional lead screw 10. The adjustable fixing assembly 9 also includes a driven plate 14. One end of the driven plate 14 is fixedly connected to the outside of the active block 13. A guide plate 16 is fixedly connected to the bottom of the other end of the driven plate 14. A guide groove 15 is provided at the bottom of the cavity 11. One end of the guide plate 16 passes through the guide groove 15 and is fixedly connected to a clamping plate 17, ensuring the movement path of the clamping plate 17. A positioning block 18 is fixedly connected to the bottom of the wheel stop body 1. The positioning block 18 is located inside the clamping plate 17. The friction plate 2 is made of polyurethane, which has good compressive strength and tear resistance. The guide plate 16 slides inside the guide groove 15, improving the stability of the guide plate 16 during movement.

[0029] Working principle: During use, rotating the rotating block 12 drives the bidirectional lead screw 10 to rotate, which in turn drives the driving block 13 to move. The driving block 13 then drives the driven plate 14 and the guide plate 16 to move, causing the clamping plate 17 to move along a fixed path under the limit of the guide groove 15. By adjusting the distance between the clamping plate 17 and the positioning block 18, different rail types can be accommodated, improving versatility and flexibility. When installing the friction plate 2, the mounting block 4 is aligned with the mounting groove 5 and inserted, allowing the screw 7 to pass through the through hole 6. The nut 8 is then tightened to secure the friction plate 2 to the wheel stop body 1. When the friction plate 2 wears out, the nut 8 is unscrewed and the screw 7 is pulled out, allowing the mounting block 4 to slide out of the mounting groove 5 for quick replacement of the friction plate 2, reducing overall replacement costs and maintenance expenses.
