Description

Technical Field

[0001] This utility model relates to the field of rail joint clamp technology, and in particular to a rail joint clamp device for improving wheel-rail impact. Background Technology

[0002] In railway transportation systems, rail joints are crucial components connecting two rail sections and are the core stress points for wheel-rail interaction. The design flaws of traditional rail joint devices are becoming increasingly apparent. Traditional devices often use a single clamp plate directly connected to the rail with bolts, which only achieves basic fixing functions and lacks a targeted stable support structure. This leads to easy displacement and deformation at the rail joint, and significant stress concentration when the wheel and rail are in contact. At the same time, traditional fixing components are mostly rigid connections without buffering and shock absorption designs. The impact energy generated when a train passes cannot be effectively dispersed, which not only accelerates wheel and rail wear and shortens the service life of rails and wheels, but also causes severe vibration and noise, affecting the smoothness of train operation and even damaging the track foundation structure, increasing maintenance costs and safety hazards. This makes it difficult to meet the modern railway's requirements for efficient, safe, and low-maintenance operation.

[0003] Existing devices cannot provide precise support and restraint for rail joints from multiple angles, resulting in uneven force and greater impact when the wheel and rail come into contact. During fixed connection, there is a lack of multi-stage fixing components to disperse the impact force, and the connection is not strong enough and the effect of buffering and dispersing the impact force is insufficient, thus making it difficult to significantly improve the wheel-rail impact problem. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rail joint clamping device to improve wheel-rail impact.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A rail joint clamping device for improving wheel-rail impact includes a rail with slots on both sides, two joint pedals fixedly connected to the inner sides of the two rails, three openings on one side of the rail, and two stabilizing mechanisms fixedly connected to both sides of the two rails.

[0006] As a further embodiment of this utility model: a joint clamp is fixedly connected to one side of the stabilizing mechanism, and six openings of the same size are provided on one side of the stabilizing mechanism and the joint clamp. A fixing mechanism is movably connected inside the rail, the stabilizing mechanism and the joint clamp, and the fixing mechanism passes through the two joint clamps.

[0007] As a further embodiment of this utility model: the stabilizing mechanism includes a connecting plate, an upper support bracket, and a lower support plate, wherein the connecting plate is movably connected to one side of the rail, and the upper support bracket is fixedly connected to the top of the connecting plate.

[0008] As a further embodiment of this utility model: the joint pedal is fixedly connected to the top of the upper support bracket, the lower support plate is fixedly connected to the bottom of the connecting plate, and the upper support bracket and the lower support plate are respectively attached to the inner wall of the rail.

[0009] As a further embodiment of this utility model: the fixing mechanism includes an insulating sleeve, a first nut, a hollow screw, a ring, a circular plate, a spring washer, a second nut, and a solid screw, and the insulating sleeve is movably connected to the inside of an opening on one side of the rail.

[0010] As a further embodiment of this utility model: the insulating sleeve passes through the stabilizing mechanism and the joint clamp, the hollow screw is movably connected to the inside of the insulating sleeve, and one end of the hollow screw is provided with an external thread, the ring is fixedly connected to one side of the hollow screw, the nut is movably connected to the periphery of the external thread of the hollow screw, and the solid screw is movably connected to the inside of the hollow screw, and one end of the solid screw is provided with an external thread.

[0011] As a further embodiment of this utility model: the second nut is movably connected to the periphery of the external thread of the solid screw, the circular plate is fixedly connected to one side of the solid screw, and the solid screw is movably connected to one side of the first nut, and the spring washer is movably connected to the inner sides of the circular plate and the first nut.

[0012] Compared with the prior art, this utility model provides a rail joint clamping device for improving wheel-rail impact, which has the following beneficial effects: 1. This rail joint clamping device for improving wheel-rail impact involves connecting two rails together, using a stabilizing mechanism to ensure the joint plate fits against the rail, and then using a fixing mechanism that sequentially passes through the rail, stabilizing mechanism, and joint clamping plate to firmly connect all components. This allows the impact between the wheel and rail to be more evenly distributed when a train passes, reducing excessive local impact force, improving the smoothness of train operation, extending the service life of the rail and related components, and enhancing the safety of railway operation.

[0013] 2. This rail joint clamping device for improving wheel-rail impact involves a connecting plate that is movably connected to one side of the rail. The upper support bracket and the lower support plate are respectively attached to the inner wall of the rail. Together with the joint pedal, they provide support and limit the rail joint from both above and below. As a result, the rail joint is more stable when subjected to wheel-rail forces, and is less prone to deformation or misalignment. This effectively improves the stress situation during wheel-rail contact, further reduces impact, and makes the train pass through the joint more smoothly.

[0014] 3. This rail joint clamping device for improving wheel-rail impact involves inserting an insulating sleeve into the rail, a stabilizing mechanism, and an opening in the joint clamping plate. A hollow screw is inserted into the insulating sleeve, and a solid screw is inserted into the hollow screw. Nuts one and two, along with a circular plate and spring washers, tightly fix the components together. This ensures the strength of the connection and also disperses the force generated by wheel-rail impact through structural characteristics, making the stress at the rail joint more reasonable. This greatly improves the wheel-rail impact problem and ensures the stability and safety of railway operation.

[0015] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0021] A rail joint clamping device for improving wheel-rail impact, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes a rail 1, with slots on both sides of the rail 1, two joint pedals 2 fixedly connected to the inner sides of the two rails 1, and three openings on one side of the rail 1, and two stabilizing mechanisms 3 fixedly connected to both sides of the two rails 1.

[0022] One side of the stabilizing mechanism 3 is fixedly connected to the joint clamp 4, and six openings of the same size are opened on one side of the stabilizing mechanism 3 and the joint clamp 4. The rail 1, the stabilizing mechanism 3 and the joint clamp 4 are internally connected to the fixing mechanism 5, and the fixing mechanism 5 passes through the two joint clamps 4.

[0023] During operation, by connecting two rails 1, the stabilizing mechanism 3 makes the joint plate 2 fit against the rail 1, and then the fixing mechanism 5 passes through the rail 1, the stabilizing mechanism 3 and the joint plate 4 in sequence to firmly connect the components. As a result, when the train passes, the impact between the wheel and rail is more evenly distributed, reducing excessive local impact force, improving the stability of train operation, extending the service life of the rails and related components, and enhancing the safety of railway operation.

[0024] To ensure the two rails are level, such as Figure 3 As shown, the stabilizing mechanism 3 includes a connecting plate 301, an upper support bracket 302, and a lower support plate 303. The connecting plate 301 is movably connected to one side of the rail 1, and the upper support bracket 302 is fixedly connected to the top of the connecting plate 301.

[0025] The joint pedal 2 is fixedly connected to the top of the upper support bracket 302, and the lower support plate 303 is fixedly connected to the bottom of the connecting plate 301. The upper support bracket 302 and the lower support plate 303 are respectively attached to the inner wall of the rail 1.

[0026] During operation, the connecting plate 301 is movably connected to one side of the rail 1. The upper support bracket 302 and the lower support plate 303 respectively fit against the inner wall of the rail 1. Together with the joint pedal 2, they support and limit the joint of the rail 1 from the top and bottom. As a result, the joint of the rail 1 is more stable when it is subjected to wheel-rail force, and it is not easy to deform or misalign. This effectively improves the stress situation when the wheel and rail are in contact, further reduces the impact, and makes the train pass through the joint more smoothly.

[0027] To secure the rail 1 and the joint clamp 4, such as Figure 4 and Figure 5 As shown, the fixing mechanism 5 includes an insulating sleeve 501, a first nut 502, a hollow screw 503, a ring 504, a circular plate 505, a spring washer 506, a second nut 507, and a solid screw 508, and the insulating sleeve 501 is movably connected to the inside of an opening on one side of the rail 1.

[0028] The insulating sleeve 501 passes through the stabilizing mechanism 3 and the joint clamp 4. The hollow screw 503 is movably connected to the inside of the insulating sleeve 501, and one end of the hollow screw 503 is provided with an external thread. The ring 504 is fixedly connected to one side of the hollow screw 503. The nut 502 is movably connected to the periphery of the external thread of the hollow screw 503. The solid screw 508 is movably connected to the inside of the hollow screw 503, and one end of the solid screw 508 is provided with an external thread.

[0029] Nut 2 507 is movably connected to the periphery of the external thread of solid screw 508, round plate 505 is fixedly connected to one side of solid screw 508, and solid screw 508 is movably connected to one side of nut 1 502, and spring washer 506 is movably connected to the opposite inner sides of round plate 505 and nut 1 502.

[0030] During operation, the insulating sleeve 501 is inserted into the openings of the rail 1, the stabilizing mechanism 3, and the joint clamp 4. The hollow screw 503 is inserted into the insulating sleeve 501, and the solid screw 508 is inserted into the hollow screw 503. The components are tightly fixed by nuts 1 502 and 2 507 in conjunction with the round plate 505 and spring washer 506. This ensures the firmness of the connection and can also disperse the force generated by wheel-rail impact through structural characteristics, making the stress at the joint of rail 1 more reasonable, greatly improving the wheel-rail impact problem, and ensuring the stability and safety of railway operation.

[0031] Working principle: By connecting two rails 1, the upper support bracket 302 and the lower support plate 303 respectively fit against the inner wall of the rail 1, and with the joint pedal 2, the joint of the rail 1 is supported and limited from the top and bottom.

[0032] The insulating sleeve 501 is then inserted through the openings in the rail 1, the stabilizing mechanism 3, and the joint clamp 4. The hollow screw 503 is inserted into the insulating sleeve 501, and the solid screw 508 is inserted into the hollow screw 503. The components are then tightly fixed by the nuts 502 and 507, the round plate 505, the spring washer 506, etc.
