[0001] This utility model relates to the field of track technology, and in particular to track switches and track switch components. Background Technology
[0002] A turnout, also known as a railway turnout, is a track device used by locomotives and rolling stock to switch from one track to another or cross over another. It is an important component of railway tracks. Turnouts are used to change the direction of train travel, ensuring smooth train operation on the railway network. Turnouts can be classified according to their structure, purpose, and location, such as single turnouts and double-crossing turnouts on main lines and connecting lines, as well as special-shaped frogs and wheel guard turnouts designed and manufactured to adapt to adverse geological conditions or special needs.
[0003] Existing turnouts and turnout components typically require manual lubrication, which is not only time-consuming and labor-intensive, but also prone to uneven or missed lubrication during manual operation, leading to poor lubrication results and increased maintenance costs.
[0004] Therefore, it is necessary to propose a turnout and turnout components to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to provide a turnout and a turnout assembly to solve the problem that turnouts require manual lubrication, which is not only time-consuming and labor-intensive, but also results in poor lubrication due to uneven or missed lubrication during operation, thus increasing maintenance costs.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a rail turnout, comprising multiple sleepers, wherein a first fixed rail and a second fixed rail are fixedly installed on both sides of the top surface of the sleepers, and a first movable rail and a second movable rail are provided between the first fixed rail and the second fixed rail, wherein the ends of the first movable rail and the second movable rail are fixedly installed on the top surface of the multiple sleepers on one side close to each other, and the ends of the first movable rail and the second movable rail are slidably connected to the top surface of the multiple sleepers on one side far away from each other;
[0007] An oil storage box is fixedly connected to the top surface of one of the sleepers. Two through holes are opened through the top of both sides of the oil storage box. An elastic sheet is fixedly connected inside the through holes. Two oil outlet holes are opened through the bottom of both sides of the oil storage box. A sponge strip is fixedly connected to the bottom surface inside the oil storage box. The protruding part of the sponge strip is located inside the oil outlet hole. The first moving track and the second moving track are respectively in active contact with the corresponding elastic sheet on their respective sides.
[0008] Preferably, the oil storage box is located on one side away from each other at the ends of the first and second moving tracks.
[0009] Preferably, the elastic sheet is elastic.
[0010] Preferably, the elastic sheet is located on the outer surface of the oil reservoir under normal conditions.
[0011] This utility model also discloses a track turnout assembly, which includes an extension rod. The ends of the two sleepers are fixedly connected to the extension rod.

[0024] 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.
[0025] This utility model addresses the problem that manual lubrication of railway turnouts is not only time-consuming and labor-intensive, but also prone to uneven or missed lubrication, leading to poor lubrication results and increased maintenance costs. It provides a solution such as… Figures 1-3 The track turnout shown includes multiple sleepers 1. A first fixed rail 3 and a second fixed rail 31 are fixedly installed on both sides of the top surface of each sleeper 1. A first movable rail 32 and a second movable rail 33 are arranged between the first fixed rail 3 and the second fixed rail 31. The ends of the first movable rail 32 and the second movable rail 33 are fixedly installed on the top surface of the multiple sleepers 1 on one side close to each other, and slidably connected to the top surface of the multiple sleepers 1 on the other side far apart from each other. At railway junctions or places where a change of direction is required, the track turnout can guide trains onto a predetermined track. When train guidance is needed, the ends of the first movable rail 32 and the second movable rail 33 that are farther apart are moved. When the first movable rail 32 approaches the second fixed rail 31 and the second movable rail 33 moves away from the first fixed rail 3, the train moves from the second fixed rail 31 onto the first movable rail 32 and moves forward normally. When a change of direction is needed, the first movable rail 32 moves away from the second fixed rail 31 and the second movable rail 33 moves closer to the first fixed rail 3. At this time, the train is guided to enter another route, completing the change of direction.
[0026] Furthermore, an oil storage box 4 is fixedly connected to the top surface of a sleeper 1. Two through holes 41 are opened through the top of both sides of the oil storage box 4. An elastic sheet 42 is fixedly connected inside the through hole 41. Two oil outlet holes 43 are opened through the bottom of both sides of the oil storage box 4. A sponge strip 44 is fixedly connected to the bottom surface inside the oil storage box 4. The protruding part of the sponge strip 44 is located inside the oil outlet hole 43. The first moving track 32 and the second moving track 33 are respectively in active contact with the corresponding elastic sheet 42 on one side close to each other. Lubricating oil is added inside the oil storage box 4. The oil storage box 4 has a valve for sealing and opening / closing, which is used to add lubricating oil. The valve is a mature technology in the prior art and is not shown in the figure. It will not be described in detail here.
[0027] It should be noted that when the first moving track 32 and the second moving track 33 move, they move away from the elastic plate 42. At this time, the elastic plate 42 bounces outward, and the air pressure inside the oil storage box 4 increases. When the first moving track 32 and the second moving track 33 move to contact the elastic plate 42, the inner wall of the first moving track 32 or the second moving track 33 squeezes the elastic plate 42, and the elastic plate 42 moves inward under force. The air pressure inside the oil storage box 4 decreases, and the lubricating oil flows out from the oil outlet 43 along the sponge strip 44. The flowing lubricating oil contacts the first moving track 32 and the second moving track 33 and lubricates them. After the lubricating oil flows out, a thin lubricating oil film can be formed between the first moving track 32, the second moving track 33 and the sleeper 1. The oil film can significantly reduce the direct contact between the two, reduce friction and wear, and extend the service life of the first moving track 32, the second moving track 33 and the sleeper 1.
[0028] During the movement of the first moving track 32 and the second moving track 33, lubrication can be automatically provided to the components. The lubrication is uniform and effective, saving time and effort and reducing maintenance costs.
[0029] Due to the setting of the sponge strip 44, the lubricating oil inside the oil reservoir 4 will not flow out when the elastic sheet 42 is not subjected to external force.
[0030] It should be noted that the first fixed track 3, the second fixed track 31, the first moving track 32, and the second moving track 33 are fixed to the sleeper 1 by bolts and mounting parts, which is a mature technology in the prior art and will not be described in detail here.
[0031] In this invention, the elastic sheet 42 is elastic; the elastic sheet 42 is designed to be elastic so that when the first moving track 32 or the second moving track 33 moves away from the elastic sheet 42, the elastic sheet 42 can return to its original position, thereby facilitating the subsequent repeated application of lubricating oil to the position where the first moving track 32 or the second moving track 33 contacts the sleeper 1.
[0032] It should be noted that the elastic sheet 42 is normally located on the outer surface of the oil reservoir 4; the elastic sheet 42 protrudes outward in the normal state, and when the first moving track 32 and the second moving track 33 move, they come into contact with the elastic sheet 42 on one side, thereby squeezing out the lubricating oil inside the oil reservoir 4 to achieve the lubrication effect.
[0033] In this invention, the oil storage box 4 is located on the side away from each other at the ends of the first moving track 32 and the second moving track 33; the oil storage box 4 is a limiting structure between the first moving track 32 and the second moving track 33, which can ensure that the first moving track 32 and the second moving track 33 remain stable in a specific position and prevent safety hazards caused by track deformation or displacement.
[0034] This utility model also discloses a track switch assembly, which includes an extension rod 11. The ends of the two sleepers 1 are fixedly connected to the extension rod 11. The extension rod 11 is located on a side away from the ends of the first moving track 32 and the second moving track 33. Multiple fixing plates 12 are fixedly connected between the two extension rods 11, and electric cylinders 2 are fixedly connected between the multiple fixing plates 12. The cooperation between the extension rod 11 and the fixing plates 12 helps to fix the electric cylinder 2. The electric cylinder 2 is located at a distance from the ends of the first moving track 32 and the second moving track 33. When it is necessary to change the direction of the track, the electric cylinder 2 is opened, and the electric cylinder 2 drives the piston rod 21 to move.
[0035] It should be noted that the electric cylinder 2 has a piston rod 21 on its side wall, and a connecting rod 22 is fixedly connected to the end of the piston rod 21. The first moving track 32 and the second moving track 33 are respectively fixedly connected to a connecting block 23 on one side close to each other. The connecting block 23 is fixedly connected to the top surface of the connecting rod 22. The piston rod 21 drives the connecting rod 22 at the end to move, and drives the first moving track 32 and the second moving track 33 to move through the connecting block 23, thus completing the change of direction of the track.
[0036] It should also be noted that the connecting block 23 is fixed to the connecting rod 22 by bolts, which is a mature technology in the prior art and will not be described in detail here.
