Description

Technical Field

[0001] The utility model belongs to the technical field of turnout guide wheel guard rails, and particularly relates to an adjustable anti-climbing turnout guide wheel guard rail. Background Art

[0002] The turnout guide wheel guard rail is provided to prevent the vehicle wheel pair from rubbing and colliding with the switch rail tip when entering the switch rail tip. Its upper cantilever can apply a lateral force to the wheel, guiding it to move to the other side away from the switch rail tip, reducing the wear of the curved switch rail. Currently, in many guard rails, most are made of channel-shaped steel guard rails through bending and planing. Due to reasons such as the wear of the locomotive wheel edge, small turnout radius, small rail gauge, and small gap between the guide guard rail and the basic rail, in actual work, the small gap between the guide guard rail and the basic rail and the wear of the wheel flange will easily cause the outside of the wheel to be in close contact with the guard rail, thus aggravating the wear of the guard rail and even causing the fracture of the upper cantilever of the guard rail. Therefore, people increase the thickness of the upper cantilever of the turnout guide wheel guard rail and shorten its length to increase its strength. However, new problems will arise. The long-term interaction between the guard rail and the wheel will cause the guard rail to wear and form a rolling groove inward, forming a step. In this situation, if the locomotive speed is too fast, the wheel will climb onto the guard rail, leading to accidents. At the same time, after the length of the upper cantilever is reduced, the adjustable range is reduced. Therefore, after a period of wear, the turnout guide wheel guard rail needs to be replaced as a whole, resulting in a low service life. Summary of the Invention

[0003] The purpose of the utility model is to provide an adjustable anti-climbing turnout guide wheel guard rail to solve the problems existing in the prior art.

[0004] The technical solution adopted by the utility model to solve its technical problems is: an adjustable anti-climbing turnout guide wheel guard rail, including a base plate body, a support plate is welded on the base plate body, the support plate is connected with a channel-shaped guide guard rail body through a connecting bolt, a 45-degree chamfer is provided at the contact end of the channel-shaped guide guard rail body with the wheel, and the vertical distance between the top of the chamfer of the channel-shaped guide guard rail body and the wheel tread of the basic rail is 5 mm.

[0005] Further, an adjustment gasket is provided between the support plate and the channel-shaped guide guard rail body.

[0006] Further, upper and lower cantilevers are integrally formed at the upper and lower ends of the channel-shaped guide guard rail body respectively. The thickness of the upper cantilever is 35 mm, the length is 75 mm, the outer end of the upper cantilever is the contact end of the channel-shaped guide guard rail body with the wheel, and the chamfer is opened at the bottom of the outer end of the upper cantilever, and the chamfer size is 15 mm × 45°.

[0007] The utility model has the following beneficial effects:

[0008] 1. The trough-shaped guiding guard rail body of the present utility model can effectively avoid the generation of rolling grooves, prevent the wheels from climbing the guard rail, has high strength, will not break, and has a long service life.

[0009] 2. By opening a chamfer on the upper cantilever of the trough-shaped guiding guard rail body, the contact part between the trough-shaped guiding guard rail body and the wheels is made thin, thereby avoiding the formation of rolling grooves on the relatively thick upper cantilever after frequent contact with the wheels, and further preventing the wheels from climbing the guard rail.

[0010] 3. By thickening the thickness of the upper cantilever of the trough-shaped guiding guard rail body to 35 mm, the strength of the upper cantilever is improved, preventing the upper cantilever from breaking from the root after frequent contact with the wheels.

[0011] 4. By lengthening the length of the upper cantilever of the trough-shaped guiding guard rail body to 75 mm, it can be adjusted multiple times after being worn by the wheels, thereby extending the service life of the trough-shaped guiding guard rail body. Description of the Drawings

[0017] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following further describes the present utility model in detail with reference to specific embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0018] Comparative Example 1:

[0019] As Figure 3 shown, when the upper cantilever 7 of the trough-shaped guiding guard rail body 4 in the prior art is relatively thick, rolling grooves appear after frequent contact with the wheels 9, which easily causes the wheels 9 to climb onto the trough-shaped guiding guard rail body 4, leading to safety accidents.

[0020] Comparative Example 2:

[0021] As Figure 4 shown, when the upper cantilever 7 of the trough-shaped guide guard rail body 4 in the prior art is relatively thin, after frequent contact with the wheel 9, the upper cantilever 7 of the trough-shaped guide guard rail body 4 breaks from the root, losing the function of protecting the switch rail 10 and reducing the service life of the switch rail 10.

[0022] Example 1:

[0023] As Figure 1-2 shown, an adjustable anti-climbing turnout guide wheel guard rail includes a base plate body 1, a support plate 2 is welded on the base plate body 1, the support plate 2 is connected with a trough-shaped guide guard rail body 4 through a connecting bolt 3, a 45-degree chamfer 5 is arranged at the contact end of the trough-shaped guide guard rail body 4 and the wheel 9, and the vertical distance between the top of the chamfer 5 of the trough-shaped guide guard rail body 4 and the tread of the wheel 9 of the stock rail 11 is 5 mm.

[0024] An adjustment gasket 6 is provided between the support plate 2 and the trough-shaped guide guard rail body 4. The adjustment gasket 6 adjusts the distance between the trough-shaped guide guard rail body 4 and the wheel flange of the wheel 9. When the upper cantilever 7 of the trough-shaped guide guard rail body 4 wears and becomes shorter, the connecting bolt 3 can be loosened and the adjustment gasket 6 can be thickened.

[0025] Upper and lower ends of the trough-shaped guide guard rail body 4 are integrally formed with an upper cantilever 7 and a lower cantilever 8 respectively. The thickness of the upper cantilever 7 is 35 mm and the length is 75 mm. The outer end of the upper cantilever 7 is the contact end of the trough-shaped guide guard rail body 4 and the wheel 9, and the chamfer 5 is provided at the bottom of the outer end of the upper cantilever 7. The size of the chamfer 5 is 15 mm × 45°.

[0026] Compared with Comparative Examples 1 and 2, the root of the upper cantilever 7 of the trough-shaped guide guard rail body 4 is relatively thick, reaching 35 mm, so it has high strength and will not break. The chamfer 5 is relatively thin and will not form a rolling groove, so the wheel 9 will not climb onto the trough-shaped guide guard rail body 4, and the safety is good. At the same time, the length of the upper cantilever 7 of the trough-shaped guide guard rail body 4 can be processed to more than 70 mm. After the upper cantilever 7 is worn and becomes shorter, the adjustment gasket 6 can be thickened multiple times, so the service life is relatively long.

[0027] The working principle of the present utility model is:

[0028] During use, the installation method is the same as that of the guard rail in the prior art. The stock rail 11 is located on the base plate body 1, the switch rail 10 is installed on one side of the stock rail 11, the support plate 2 is installed on the other side of the stock rail 11, the outer end of the upper cantilever 7 of the trough-shaped guide guard rail body 4 abuts against the wheel flange of the passing wheel 9, and the vertical distance between the top of the chamfer 5 and the tread of the wheel 9 of the stock rail 11 is 5 mm.

[0029] When the wheel 9 passes by, the outer end of the cantilever 7 on the trough-shaped guide guard rail body 4 contacts the outer side of the wheel 9, pushing the wheel 9 to move laterally, so that the other side of the wheel 9 is far away from the tip of the working edge of the switch rail 10, thereby prolonging the service life of the switch rail 10. After the outer end of the cantilever 7 on the trough-shaped guide guard rail body 4 contacts the outer side of the wheel 9 frequently, the outer end of the cantilever 7 on the trough-shaped guide guard rail body 4 wears. Since there is a chamfer 5 at the bottom of the cantilever 7 on the trough-shaped guide guard rail body 4, the chamfer 5 moves inward as the worn part approaches, and the thickness of the trough-shaped guide guard rail body 4 at the chamfer 5 is relatively thin, so that a rolling groove will not be formed, thereby preventing the wheel 9 from climbing onto the trough-shaped guide guard rail body 4, thus ensuring the safety of the train's progress.

[0030] Due to the setting of the chamfer 5, the cantilever 7 on the trough-shaped guide guard rail body 4 can be thickened to more than 30 mm, so as to improve the strength and prevent the cantilever 7 from breaking from the root. At the same time, the length of the cantilever 7 can be extended to more than 70 mm. After the outer end of the cantilever 7 wears, the outer end of the cantilever 7 can be moved closer to the wheel 9 by thickening the adjustment gasket 6, so as to continue to push the wheel 9 to move laterally to protect the switch rail 10, thereby playing a role in prolonging the service life of the trough-shaped guide guard rail body 4.

[0031] The embodiments described above are only descriptions of the preferred embodiments of the present invention, and do not limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various variations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention should all fall within the protection scope of the present invention.
