Description

Technical Field

[0001] The utility model relates to the technical field of concrete sleepers, in particular to a reinforcement device for high-strength concrete sleepers. Background Art

[0002] Nowadays, most sleepers are reinforced concrete sleepers. During the long-term use of such reinforced concrete sleepers, due to long-term exposure to wind, sun, and heavy object extrusion, phenomena such as fracture are likely to occur.

[0003] After retrieval, the Chinese patent with the publication number CN217351956U discloses a sleeper with a reinforcement component, which includes a sleeper body and two reinforcement components. The sleeper body is arranged in a long strip shape, and the two reinforcement components are symmetrically arranged on both sides of the sleeper body. The reinforcement component includes two fixing blocks. One side of each of the two fixing blocks is fixedly connected to one side of the sleeper body. Through holes are opened on the sides of the two fixing blocks, and a reinforcement rod is slidably sleeved in the inner cavities of the two through holes. A locking component is provided at one end of the reinforcement rod. The invention utilizes the arrangement of the two fixing blocks and the reinforcement rod. By arranging the reinforcement rod on one side of the sleeper through the two fixing blocks, the strength of the reinforcement rod plays a role in reinforcing the sleeper, thereby improving the strength of the sleeper during use.

[0004] In the above-mentioned prior art solution, by rotating the locking nut and pulling the reinforcement rod to move, the push-pull rod moves towards the fixing block, and the sleeper body is pulled together to reinforce the sleeper body. However, during actual use, when a train passes over the sleeper, the sleeper will vibrate, resulting in the loosening of the locking nut and the inability to complete the reinforcement work. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model proposes a reinforcement device for high-strength concrete sleepers. By clamping the clamping block on the side wall of the limiting flower wheel, the position of the contraction rod is positioned to ensure the stability of the position of the contraction rod, and to avoid the loosening of the fixed pull rod caused by the vibration generated when the train passes over the top of the sleeper body.

[0006] The technical solution for achieving the purpose of the utility model is as follows: A reinforcement device for high-strength concrete sleepers includes a sleeper body. Fixed grooves are opened on the front and rear side walls of the sleeper body, and fixed pull rods are clamped inside the two fixed grooves. The fixed pull rods are in a "C" shape. Two contraction rods are arranged outside the sleeper body. Threaded connection sleeves are respectively arranged at both ends of each contraction rod. The two threaded connection sleeves on the contraction rods are respectively fixedly connected to the adjacent ends of the fixed pull rods. A fixed screw block is fixedly installed on the side wall of the contraction rod, and a limiting flower wheel is fixedly installed on the side wall of the contraction rod. Two storage grooves are opened inside the sleeper body, and the two storage grooves are respectively aligned with the two limiting flower wheels. A clamping block is slidably installed inside the storage groove.

[0007] In some embodiments, a connection block is slidably installed inside the storage groove, and the connection block is fixedly connected to the clamping block.

[0008] In some embodiments, a positioning groove is formed on the top wall surface of the sleeper body. A moving screw is rotatably installed on the inner bottom wall surface of the positioning groove. Adjusting grooves are formed on the side wall surfaces of two adjacent storage grooves, and both adjusting grooves communicate with the inside of the positioning groove. Push rods are slidably installed inside both adjusting grooves, and a pushing block is threadedly installed on the side wall of the moving screw.

[0009] In some embodiments, the pushing block is frustum-shaped, and the side wall of the pushing block is in contact with one end of the two push rods that are close to each other.

[0010] In some embodiments, a limiting groove is formed inside the positioning groove, and a limiting block is slidably installed inside the limiting groove. The limiting block is fixedly installed on the side wall of the pushing block.

[0011] In some embodiments, the thread directions of the contraction screws at both ends of the contraction rod are opposite, and the clamping block is stuck on the side wall of the adjacent limiting flower wheel.

[0012] Compared with the prior art, the remarkable advantages of the present utility model are as follows:

[0013] Firstly: In the present utility model, since the thread directions of the two contraction screws at both ends of the contraction rod are opposite, when the fixed screw block is rotated, the two contraction screws will contract towards the inside of the contraction rod. Therefore, the two fixed pull rods will approach each other, pull the sleeper body, reinforce the sleeper body, and ensure the strength of the sleeper body. By sticking the clamping block on the side wall of the limiting flower wheel, the position of the contraction rod is positioned to ensure the stable position of the contraction rod and avoid the loosening of the fixed pull rod caused by the vibration generated when the train passes over the top of the sleeper body; the problem that the existing lock nuts are prone to loosening is solved.

[0014] Secondly: In the present utility model, by rotating the moving screw to move the pushing block downward, the side wall of the pushing block pushes the two push rods to extend towards the opposite sides. Therefore, the two clamping blocks extend outward, making the clamping connection between the clamping block and the limiting flower wheel tighter, ensuring the stable position of the limiting flower wheel. When the pushing block moves downward by a large distance, the clamping block will push the contraction rod to move away from the sleeper body. Therefore, one end of the two fixed pull rods close to each other expands outward, and the two fixed pull rods can further gather the sleeper body, further reinforce the sleeper body, and ensure the strength of the sleeper body.

[0022] The present utility model will be described in detail below. The technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0023] The present utility model provides a reinforcement device for a high-strength concrete sleeper by making improvements. The technical solution of the present utility model is as follows:

[0024] As Figures 1-4As shown in the figure, a reinforcement device for a high-strength concrete sleeper includes a sleeper main body 1. Fixed grooves 2 are provided on the front and rear side walls of the sleeper main body 1. Fixed pull rods 3 are clamped inside the two fixed grooves 2. The fixed pull rods 3 are in a "C" shape. Two contraction rods 4 are arranged outside the sleeper main body 1. Both ends of the contraction rods 4 are threadedly connected with contraction screws 5. The thread directions of the contraction screws 5 at both ends of the contraction rods 4 are opposite. The opposite ends of the two contraction screws 5 on the contraction rods 4 are respectively fixedly connected to the adjacent ends of the fixed pull rods 3. A fixed screw block 6 is fixedly installed on the side wall of the contraction rod 4. Since the thread directions of the two contraction screws 5 at both ends of the contraction rod 4 are opposite, when the fixed screw block 6 is rotated, the two contraction screws 5 will contract towards the inside of the contraction rod 4, and the two fixed pull rods 3 will approach each other accordingly, pulling the sleeper main body 1 and strengthening the sleeper main body 1 to ensure the strength of the sleeper main body 1. A limit flower wheel 7 is fixedly installed on the side wall of the contraction rod 4. Two storage grooves 8 are provided inside the sleeper main body 1. The two storage grooves 8 are respectively aligned with the two limit flower wheels 7. A clamping block 9 is slidably installed inside the storage groove 8. The clamping block 9 is clamped on the side wall of the adjacent limit flower wheel 7. By clamping the clamping block 9 on the side wall of the limit flower wheel 7, the position of the contraction rod 4 is positioned to ensure the stable position of the contraction rod 4, avoiding the loosening of the contraction rod 4 caused by the vibration generated when the train passes over the top of the sleeper main body 1, and preventing the situation where the distance between the two fixed pull rods 3 becomes farther and the sleeper main body 1 cannot be strengthened.

[0025] As Figures 1-2As shown, in one embodiment, in order to ensure the stable position of the clamping block 9, a connecting block 10 is slidably installed inside the receiving groove 8, and the connecting block 10 is fixedly connected to the clamping block 9; the position of the clamping block 9 is ensured to be stable through the connecting block 10, avoiding the situation that the clamping block 9 shakes as the limiting flower wheel 7 rotates; a positioning groove 11 is formed in the top wall surface of the sleeper body 1, a moving screw 12 is rotatably installed on the inner bottom wall surface of the positioning groove 11, adjusting grooves 13 are formed in the side wall surfaces of two adjacent receiving grooves 8, both of the two adjusting grooves 13 communicate with the inside of the positioning groove 11, a push rod 15 is slidably installed in each of the two adjusting grooves 13, a push block 14 is threadedly installed on the side wall of the moving screw 12, the push block 14 is frustum-shaped, and the side wall of the push block 14 is in contact with one end of the two push rods 15 close to each other; by rotating the moving screw 12, the push block 14 moves downward, and the side wall of the push block 14 pushes the two push rods 15 to extend away from each other, so that the two clamping blocks 9 extend outward, making the clamping between the clamping block 9 and the limiting flower wheel 7 tighter, ensuring the stable position of the limiting flower wheel 7. When the push block 14 moves downward by a large distance, the clamping block 9 will push the retraction rod 4 to move away from the sleeper body 1, and the adjacent ends of the two fixed pull rods 3 will expand outward, so that the two fixed pull rods 3 can further gather the sleeper body 1 and further reinforce the sleeper body 1 to ensure the strength of the sleeper body 1.

[0026] As Figures 1-2 shown, in one embodiment, in order to enable the push block 14 to slide stably, a limiting groove 16 is formed inside the positioning groove 11, a limiting block 17 is slidably installed inside the limiting groove 16, and the limiting block 17 is fixedly installed on the side wall of the push block 14; the position of the push block 14 is limited by the limiting groove 16 and the limiting block 17 to ensure that the push block 14 can move up and down stably.

[0027] The specific working method is as follows: Since the thread directions of the two contraction screws 5 at both ends of the contraction rod 4 are opposite, when the fixed screw block 6 is rotated, the two contraction screws 5 will contract towards the inside of the contraction rod 4, and the two fixed pull rods 3 will thus approach each other, pulling the sleeper body 1 and strengthening the sleeper body 1 to ensure the strength of the sleeper body 1; by clamping the clamping block 9 on the side wall of the limit flower wheel 7, the position of the contraction rod 4 is positioned to ensure the stable position of the contraction rod 4 and avoid the loosening of the contraction rod 4 caused by the vibration generated when the train passes over the top of the sleeper body 1, resulting in the distance between the two fixed pull rods 3 being pulled apart and the situation where the sleeper body 1 cannot be strengthened; by rotating the moving screw 12 to move the push block 14 downward, the side wall of the push block 14 pushes the two push rods 15 to extend towards the opposite sides, and the two clamping blocks 9 thus extend outwards, making the clamping between the clamping block 9 and the limit flower wheel 7 tighter and ensuring the stable position of the limit flower wheel 7. When the push block 14 moves downward by a large distance, the clamping block 9 will push the contraction rod 4 to move away from the sleeper body 1, and the adjacent ends of the two fixed pull rods 3 will thus expand outwards. Therefore, the two fixed pull rods 3 can further gather the sleeper body 1 and further strengthen the sleeper body 1 to ensure the strength of the sleeper body 1.

Matters not covered in the present utility model belong to the common general knowledge of those skilled in the art.
