Description

Technical Field

[0001] The utility model relates to the technical field of rail transit, in particular to an anti - overturning mechanism for stress dispersion of seamless line rails in the field of rail transit. Background Technique

[0002] In the field of rail transit, especially in railway systems using seamless lines, the stress dispersion of rails is a key issue. After the rails have been under the pressure and vibration brought by train operation for a long time, stress will accumulate. If these stresses cannot be properly released and managed, it will lead to the deformation or overturning of the rails. Especially in curved sections, due to the change in terrain elevation and the design of the curve radius, the rails are more vulnerable to uneven stress distribution, increasing the risk of overturning.

[0003] Traditional solutions mainly rely on basic track design and regular maintenance inspections. However, they cannot completely prevent safety problems caused by stress concentration. Therefore, an anti - overturning mechanism for stress dispersion of seamless line rails in the field of rail transit is proposed to solve the above problems. Summary of the Utility Model

[0004] To make up for the above deficiencies, the utility model provides an anti - overturning mechanism for stress dispersion of seamless line rails in the field of rail transit, aiming to improve the problems in the prior art that rely on basic track design and regular maintenance inspections and cannot completely prevent safety problems caused by stress concentration.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: An anti - overturning mechanism for stress dispersion of seamless line rails in the field of rail transit, including a bearing plate. A through - groove is provided on the surface of the bearing plate, and an anti - overturning component is arranged inside the through - groove. The anti - overturning component includes a moving seat, the moving seat is slidably connected inside the through - groove, two groups of the moving seats are symmetrically arranged, and the two groups of moving seats are threadedly connected by a bidirectional screw rod. Both ends of the bidirectional screw rod are rotatably connected to the inner wall of the through - groove, and a clamping plate is fixedly connected to the surface of the moving seat.

[0006] As a further description of the above technical scheme:

[0007] Fixing components are arranged on both sides of the bearing plate. The fixing components include threaded rods, the ends of the threaded rods are fixedly connected to the side walls of the bearing plate, clamping plates are sleeved on the outer walls of the threaded rods, and nuts are threadedly connected to the outer walls of the threaded rods.

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

[0009] Multiple groups of convex strips distributed in a row are fixedly connected to the side walls of the clamping plates.

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

[0011] Four groups of the threaded rods and nuts are provided, and the four groups of the threaded rods and nuts are symmetrically arranged with the horizontal center line of the bearing plate as the axis of symmetry.

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

[0013] The shape of the buckle plate is set to be L-shaped.

[0014] As a further description of the above technical solution:

[0015] The outer wall of the bidirectional lead screw is fixedly connected with a runner, and the runner is located at the center of the bidirectional lead screw.

[0016] As a further description of the above technical solution:

[0017] The end of the buckle plate is fixedly connected with a widened plate.

[0018] The utility model has the following beneficial effects:

[0019] 1. In the utility model, by rotating the runner to drive the bidirectional lead screw to rotate, the two moving seats move in the through groove. When the buckle plate is in close contact with the side surface of the rail and the protruding edge at the bottom of the rail is clamped by the L-shaped buckle plate, the purpose of preventing the rail from overturning can be achieved. The widened plate effectively increases the contact area between the buckle plate and the bottom of the rail, disperses the pressure and force between the buckle plate and the rail, and ensures the durability and reliability of the anti-overturning mechanism.

[0020] 2. In the utility model, by rotating the nut in the fixing component, the clamping plate can slide along the outer wall of the threaded rod until the two clamping plates tightly clamp the base.

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Refer to Figure 1 - Figure 2 As shown in [drawings], an embodiment provided by the present invention is: an anti - overturning mechanism for stress relaxation of seamless line rails in the field of rail transit, including a bearing plate 1. The bearing plate 1 is the main body of the entire mechanism and is used to carry the anti - overturning assembly 3 and the fixing assembly 4. A through groove 2 is provided on the surface of the bearing plate 1. An anti - overturning assembly 3 is arranged inside the through groove 2. The through groove 2 is used to provide a track for the movement of the anti - overturning assembly 3. The anti - overturning assembly 3 is mainly installed under the rail at the straight bottom section and mainly installed on the inner side of the curved rail in the curved section. By clamping the rail and using the reaction force, it can prevent the rail from overturning due to excessive stress during the stress relaxation of the seamless line.

[0028] Refer to Figure 1 - Figure 2 As shown in [drawings], the anti - overturning assembly 3 includes a moving seat 31. The moving seat 31 is slidably connected inside the through groove 2. Two groups of moving seats 31 are symmetrically arranged, and the two groups of moving seats 31 are threadedly connected by a bidirectional lead screw 32. Both ends of the bidirectional lead screw 32 are rotatably connected to the inner wall of the through groove 2. By rotating the bidirectional lead screw 32 and the guiding action of the through groove 2 on the moving seat 31, the distance between the two groups of moving seats 31 can be adjusted. A rotating wheel 33 is fixedly connected to the outer wall of the bidirectional lead screw 32. The rotating wheel 33 is located at the center of the bidirectional lead screw 32 and is used to manually rotate the bidirectional lead screw 32. A buckle plate 34 is fixedly connected to the surface of the moving seat 31. The shape of the buckle plate 34 is set as an L - shape. A widening plate 35 is fixedly connected to the end of the buckle plate 34. The buckle plate 34 contacts the side of the rail through the movement of the moving seat 31. Since the buckle plate 34 is L - shaped, the protruding edge at the bottom of the rail can be stuck in it. The widening plate 35 is used to increase the contact area between the buckle plate 34 and the bottom of the steel plate, effectively dispersing the pressure and force between the buckle plate 34 and the rail.

[0029] Refer to Figure 1 、 Figure 3, fixed components 4 are provided on both sides of the bearing plate 1. The fixed components 4 are used to be fixed on both sides of the bearing plate 1 to stably install the entire anti-overturning mechanism in the rail transit system. The fixed component 4 includes a threaded rod 41, the end of the threaded rod 41 is fixedly connected to the side wall of the bearing plate 1, a clamping plate 42 is sleeved on the outer wall of the threaded rod 41, and the threaded rod 41 is used to provide positioning and guiding effects for the clamping plate 42. The clamping plate 42 can slide along the outer wall of the threaded rod 41. A plurality of groups of convex strips 43 distributed in a row are fixedly connected to the side wall of the clamping plate 42. A nut 44 is threadedly connected to the outer wall of the threaded rod 41, and the nut 44 is used to apply pressure to the clamping plate 42. Four groups of threaded rods 41 and nuts 44 are provided, and the four groups of threaded rods 41 and nuts 44 are symmetrically arranged with the horizontal center line of the bearing plate 1 as the axis of symmetry. By tightening the nut 44, the two clamping plates 42 can be stably clamped on the base, thereby ensuring the stability of the anti-overturning mechanism. Each group of convex strips 43 is made of rubber material, which not only enhances the friction between the clamping plate 42 and the base, but also prevents damage to the base due to excessive pressure.

[0030] Working principle: In practical applications, when this seamless track rail stress dispersion anti-overturning mechanism needs to be installed in the rail transit system, first, the installation position needs to be determined, and the installation method for the straight bottom section or the curved section needs to be selected according to the actual situation. Before installation, ensure that the bearing plate 1 is placed steadily at the predetermined position, and then fix the entire anti-overturning mechanism by adjusting the fixed component 4.

[0031] The operator only needs to rotate the nut 44 in the fixed component 4, so that the clamping plate 42 can slide along the outer wall of the threaded rod 41 until the two clamping plates 42 tightly clamp the base. Due to the existence of the convex strips 43, not only the friction between the clamping plate 42 and the base is increased, ensuring the stability of the mechanism, but also damage to the base caused by excessive pressure is avoided.

[0032] Then, drive the bidirectional lead screw 32 to rotate by rotating the runner 33. The rotation of the bidirectional lead screw 32 causes the two moving seats 31 to move in the through groove 2, thereby adjusting the distance between the buckle plate 34 and the rail. When the buckle plate 34 is in close contact with the side surface of the rail and the protruding edge at the bottom of the rail is caught by the L-shaped buckle plate 34, the purpose of preventing the rail from overturning can be achieved. The widening plate 35 effectively increases the contact area between the buckle plate 34 and the bottom of the rail, disperses the pressure and force between the buckle plate 34 and the rail, and ensures the durability and reliability of the anti-overturning mechanism.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
