Description

Technical Field

[0001] This utility model relates to the technical field of rail insulating connection clamps, specifically a basalt composite material rail insulating connection clamp. Background Technology

[0002] In railway track systems, rail insulation joints are critical components that ensure the isolation between adjacent track circuit sections and guarantee accurate and reliable signal transmission. Traditional rail insulation joints typically use materials such as rubber and nylon for insulation components, but these materials are prone to aging, wear, and deterioration of electrical insulation performance over long-term use, affecting the normal operation of the railway. Furthermore, with the continuous increase in railway transport speed and load, higher requirements are being placed on the mechanical strength and impact resistance of rail insulation joints.

[0003] In existing railway track systems, rail insulation joints are key components that ensure the isolation between adjacent track circuit sections and guarantee accurate and reliable signal transmission. Traditional rail insulation joints typically use materials such as rubber and nylon to manufacture insulation components. However, these materials are prone to aging, wear, and a decline in electrical insulation performance during long-term use, which affects the normal operation of the railway.

[0004] Therefore, a basalt composite material rail insulation connecting plate is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a basalt composite material rail insulation connecting clamp, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: including a rail body, wherein an assembly device is mounted on the side of the rail body; The assembly device includes a clamping plate body, which is placed at the bottom of the inner wall of the rail body. The clamping plate body has a threaded groove on its side, and a bolt is threaded to the inner wall of the threaded groove. The clamping plate body has a sliding groove on its front, and a baffle is slidably connected to the inner wall of the sliding groove. A sliding plate is fixedly connected to the front of the baffle. A movable rod is hinged to the side of the sliding plate through a hinge rod. A first conical block is fixedly connected to the bottom of the movable rod. A second conical block is fixedly connected to the bottom of the inner wall of the rail body. A support plate for supporting the movable rod is fixedly connected to the side of the sliding plate.

[0007] Preferably, a rubber ball for increasing the friction of the skateboard is fixedly connected to the side of the clamp body.

[0008] Preferably, the front side of the clamp body is provided with a rainwater groove to reduce rainwater adhesion.

[0009] Preferably, the rainwater channel is formed on the side of the slide plate, and the channel is T-shaped.

[0010] Preferably, the rail body is internally equipped with a sealing device for improving the sealing performance of the sliding plate and the clamp body.

[0011] Preferably, the sealing device includes a receiving groove, which is formed on the front side of the clamping plate body. A hydraulic bladder is fixedly connected to the front side of the inner wall of the receiving groove, and a hydraulic chamber is fixedly connected to the front side of the receiving groove. A hydraulic rod is slidably connected to a piston at one end inside the hydraulic chamber.

[0012] Preferably, a push rod is fixedly connected to the side of the slide plate, the push rod is fixedly connected to the back of the hydraulic rod, and the hydraulic bladder and hydraulic chamber are filled with high-viscosity hydraulic oil.

[0013] Compared with the prior art, this utility model provides a basalt composite material rail insulation connecting clamp, which has the following beneficial effects: 1. By linking the baffle, the sliding plate, and the rubber ball, the static friction between the sliding plate and the clamp body is significantly increased. Even if the train vibrates at high frequency, the sliding plate will not slip due to inertia, thus avoiding loosening of the insulation structure. The movable rod and the conical block form a mechanical self-locking mechanism to permanently fix the position of the sliding plate and prevent rebound caused by material aging or vibration. This fundamentally solves the problem of electrical clearance changes caused by creep and wear in traditional nylon insulation components.

[0014] 2. After the hydraulic bladder expands, it completely fills the gap between the slide plate and the slide groove (micron-level fit), blocking the path of rainwater and sand to enter the insulation layer and avoiding the decrease in insulation resistance due to moisture.

[0017] 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. Example

[0018] See Figures 1-4 This embodiment provides a basalt composite material rail insulation connection clamp, including a rail body 1, and an assembly device 2 is mounted on the side of the rail body 1. Assembly device 2 includes a clamp body 21, made of basalt fiber reinforced composite material, which has both high strength and insulation properties. It is installed on the inner side of the rail web of rail body 1. The clamp body 21 is placed at the bottom of the inner wall of rail body 1. The side of the clamp body 21 has a threaded groove, and the inner wall of the threaded groove is threaded with bolts 22. Mechanical fastening is achieved through the threaded groove on the side of the clamp body 21, forming a physical connection. The front of the clamp body 21 has a sliding groove 211. The T-shaped sliding groove 211 on the front of the clamp body 21 slides and engages with the baffle 23. The inner wall of the sliding groove 211 is slidably connected to the baffle. 23. A slide plate 24 is fixedly connected to the front of the baffle 23. A movable rod 28 is hinged to the side of the slide plate 24 via a hinge rod 27. The baffle 23 connects to the slide plate 24, which drives the movable rod 28 via the hinge rod 27. A first conical block 29 is fixedly connected to the bottom of the movable rod 28. A second conical block 210 is fixedly connected to the bottom of the inner wall of the rail body 1. A support plate 26 for supporting the movable rod 28 is fixedly connected to the side of the slide plate 24. The first conical block 29 at the end of the movable rod 28 wedges with the second conical block 210 at the bottom of the rail to form a self-locking structure to resist longitudinal impact from the train.

[0019] Rubber balls 212 for increasing the friction of the skateboard 24 are fixedly connected to the side of the clamp body 21. An array of rubber balls 212 is set on the side of the clamp body 21. The material of the rubber balls 212 is wear-resistant neoprene rubber, with a diameter of 3-5mm and a spacing of 10mm, which is evenly distributed to increase the frictional resistance of the skateboard 24 when it slides and prevents accidental displacement.

[0020] The front of the clamp body 21 is provided with a rainwater trough 25 to reduce rainwater adhesion, guide rainwater to drain away quickly along the trough, reduce corrosion of metal contact surfaces, avoid water accumulation leading to increased conductivity of insulation materials, and maintain the stability of track circuit.

[0021] Rainwater channel 25 is provided on the side of slide plate 24, and the channel 211 is T-shaped.

[0022] In practical use, the above-mentioned equipment fixes the clamp body 21 to the side of the rail body 1 by bolts 22, pushes the baffle 23 and the slide plate 24 to move forward, the slide plate 24 fits against the rubber ball 212, increasing the friction between the slide plate 24 and the clamp body 21. Even if the train travels from the top of the rail body 1 and generates vibration, the slide plate 24 will not easily slip. At the same time, as the slide plate 24 moves forward, it drives the movable rod 28 to move forward. The movable rod 28 drives the first conical block 29 to move forward. When the first conical block 29 contacts the inclined surface of the second conical block 210, the first conical block 29 and the movable rod 28 are squeezed by the second conical block 210, causing the movable rod 28 to rotate clockwise around the hinge rod 27. When the first conical block 29 slides past the top of the second conical block 210, the first conical block 29 is no longer squeezed by the second conical block 210. The first conical block 29 and the movable rod 28 fall and get stuck on the front of the second conical block 210 due to natural gravity. Example

[0023] See Figures 1-4 Based on Embodiment 1, the rail body 1 is equipped with a sealing device 3 to improve the sealing performance of the sliding plate 24 and the clamping plate body 21.

[0024] The sealing device 3 includes a receiving groove 31, which is opened on the front of the clamping plate body 21. A hydraulic bladder 32 is fixedly connected to the front of the inner wall of the receiving groove 31, and a hydraulic chamber 35 is fixedly connected to the front of the receiving groove 31. A hydraulic rod 33 is slidably connected to one end of the hydraulic chamber 35 by a piston.

[0025] A push rod 34 is fixedly connected to the side of the slide plate 24. The push rod 34 is fixedly connected to the back of the hydraulic rod 33. The hydraulic bladder 32 and the hydraulic chamber 35 are filled with high-viscosity hydraulic oil.

[0026] In practical use, when the baffle 23 moves forward, it drives the push rod 34 to move forward. The push rod 34 pushes the hydraulic rod 33 to move forward. When the hydraulic rod 33 moves forward, the hydraulic oil inside the hydraulic chamber 35 surges into the hydraulic bladder 32 due to the pressure caused by the hydraulic rod 33 and the piston. This causes the hydraulic bladder 32 to expand and block the gap between the slide plate 24 and the slide groove 211. Since the hydraulic chamber 35 is fixedly connected to the back of the hydraulic bladder 32, it limits the movement trajectory of the hydraulic bladder 32, further improving the waterproof effect.

[0027] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
