Description

Technical Field

[0001] This application relates to the field of rail reinforcement, and in particular to a non-destructive rail reinforcement clamping device. Background Technology

[0002] Railway transportation is a core pillar of the modern transportation system, and the stability and safety of rails are directly related to transportation efficiency and train operation safety. As railways develop towards heavy-haul and high-speed operations, the problems of rail wear and deformation are becoming increasingly serious, especially at weak points such as joints, where reinforcement is even more urgent.

[0003] Currently, there are two main conventional methods for reinforcing rail joints: one is welding reinforcement, which involves welding a reinforcing plate onto the rail surface to enhance its strength. However, subsequent replacement and maintenance are quite inconvenient, requiring the damaged rail to be cut first and then a new rail to be welded. The other is bolted reinforcement, which involves fixing the reinforcement to the rail with bolts. However, bolt holes weaken the cross-sectional strength of the rail, and the installation process is cumbersome. Utility Model Content

[0004] To address the issues of complicated rail maintenance when using welded joints and the weakening of rail cross-sectional strength due to bolt holes when using bolted joints, this application provides a non-destructive rail reinforcement and clamping device.

[0005] The rail non-destructive reinforcement and clamping device provided in this application adopts the following technical solution: A non-destructive rail reinforcement clamping device includes clamping plates disposed on both sides of the rail. The clamping plates are fixed to the rail web by applying adhesive. Multiple sets of clamping bodies are symmetrically disposed on the rail foot. Each clamping body has a first receiving groove for cooperating with the rail foot. Each pair of clamping bodies is fixed to the rail foot by a connecting component. One pair of clamping bodies is provided with a reinforcement structure to increase the contact area between the clamping plate and the clamping body. The clamping body is provided with an anti-loosening plate to prevent the connecting component from loosening.

[0006] By adopting the above technical solution, the clamping plate is fixed to the rail web by applying adhesive, avoiding the impact of high welding temperature on the rail material properties and the weakening of the rail cross-sectional strength by bolt holes; the clamping body cooperates with the rail foot through the first receiving groove and is fixed by the connecting components to achieve reinforced clamping of the rail; the reinforcement structure increases the contact area between the clamping body and the clamping plate, further enhancing the reinforcement effect; the anti-loosening plate can prevent the connecting components from loosening and ensure the stability of the device.

[0007] Optionally, a first arc-shaped block is integrally formed on the side of the clamping body near the clamping plate, and the clamping body achieves the abutment function with the clamping plate through the first arc-shaped block.

[0008] By adopting the above technical solution, under the action of the connecting components, the first arc-shaped block integrally formed on the clamping body tightly abuts against the clamping plate, thereby achieving non-destructive reinforcement of the rail.

[0009] Optionally, a limiting block is integrally formed on the side of the clamping plate near the clamping body. The limiting block works in conjunction with the first arc-shaped block to prevent the clamping body from detaching from the rail foot when the rail vibrates.

[0010] By adopting the above technical solution, when the pair of clamps are abutted and fixed on both sides of the rail by the connecting components, the limiting block integrally formed on the clamp plate can cooperate with the first arc block, thus preventing the clamps from detaching from the rail foot when the rail vibrates.

[0011] Optionally, the connecting assembly includes a double-ended bolt and two nuts. The double-ended bolt passes through a pair of clamps, and the two nuts are threaded onto both ends of the double-ended bolt, thereby fixing the pair of clamps to the rail.

[0012] By adopting the above technical solution, double-ended bolts and nuts are used to abut and fix the pairs of clamps to the rail, which achieves a stable installation of the clamps on the rail. This avoids the problems of high temperature generated by welding causing a decline in the performance of the rail material and bolt holes weakening the cross-sectional strength of the rail. Moreover, the installation process is relatively simple.

[0013] Optionally, the reinforcement structure includes a reinforcement block, a second receiving groove, and a second arc-shaped head. The reinforcement block is integrally formed on the clamping body, the second receiving groove is formed on the reinforcement block to cooperate with the rail foot, and the second arc-shaped head is integrally formed on the side of the reinforcement block near the clamping plate. The pair of reinforcement blocks are also connected and fixed to the rail by a connecting component.

[0014] By adopting the above technical solution, when the reinforcing block is abutted and fixed on the rail by the connecting component, the second receiving groove abuts and fixes the bottom of the clamp to the rail foot, and the second arc-shaped head abuts and fixes the top of the clamp to the clamp plate; under the action of the fixing component, the contact area between the clamp and the clamp plate can be increased, thereby increasing the clamping and fixing strength between the clamp and the clamp plate.

[0015] Optionally, the anti-loosening plate includes a first plate and two second plates. The first plate rotates on the side of the clamp away from the clamping plate. The two second plates are integrally formed on the first plate, and the first plate and the two second plates form a limiting space. The limiting space is used to hold the nut in place to prevent the nut from loosening.

[0016] By adopting the above technical solution, after tightening the nuts at both ends to clamp and fix the paired clamps to both sides of the rail, the first plate is lowered; the limiting space formed by the first plate and the second plate locks the nut, preventing the nut from rotating and loosening, thus ensuring the stability and reliability of the device.

[0017] Optionally, through holes are evenly spaced along the length of the clamping plate, which can reduce the weight of the clamping plate.

[0018] By adopting the above technical solution, through holes with evenly distributed intervals are opened on the clamping plate, so that the clamping plate can be reduced in weight while maintaining the necessary strength.

[0019] Optionally, a rubber layer is provided on the side of the clamping plate that abuts against the clamping body. The rubber layer is used to buffer the vibration and impact between the clamping plate and the clamping body and to prevent wear on the contact surface.

[0020] By adopting the above technical solution, when the rail vibrates, the rubber layer can buffer the vibration impact between the clamping plate and the clamping body, and avoid wear on the contact surface.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. The clamp is fixed to the rail web with an adhesive layer, which avoids the problems of high temperature generated by welding causing a decrease in the performance of the rail material and bolt drilling weakening the cross-sectional strength of the rail; 2. The connecting assembly can abut and fix the pairs of clamps to the rail, and the clamps and clamps are reinforced by a strengthening structure to increase the contact area. Anti-loosening plates are set on the clamps to prevent the nuts from loosening, which enhances the stability of the connection between the device and the rail. 3. Setting through holes in the clamping plate can ensure the strength of the clamping plate and reduce its weight. Setting a rubber layer on the side where the clamping plate abuts against the clamping body can buffer vibration and impact and avoid wear on the contact surface. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0026] This application discloses a non-destructive reinforcement and clamping device for steel rails.

[0027] Reference Figure 1 A non-destructive rail reinforcement clamping device is disclosed. This device is used to strengthen the connection strength at the joint of two rails 1, and includes a clamping plate 2, a clamping body 3, a connecting assembly 5, a reinforcing structure 6, and an anti-loosening plate 7. The clamping plate 2 is shaped to fit the web of the rail 1. Multiple sets of clamping bodies 3 are provided, with each set used in pairs located on both sides of the rail 1. The paired clamping bodies 3 are fixedly connected by the connecting assembly 5. The reinforcing structure 6 is provided on the clamping bodies 3 to increase the contact area between the clamping plate 2 and the clamping body 3, and the anti-loosening plate 7 is used to prevent the connecting assembly 5 from loosening. This solution achieves non-destructive reinforcement of the rail 1 and improves the stability of the reinforcement.

[0028] In this embodiment, the clamping bodies 3 are configured in three pairs, the reinforcing structure 6 is configured in one pair, and the connecting components 5 are configured in four groups, which are used to clamp the paired clamping bodies 3 and the reinforcing structure 6 respectively.

[0029] Reference Figure 1 and Figure 2 The shape of the clamping plate 2 fits snugly against the web of the rail 1, and the clamping plate 2 is fixed to the rail 1 with a high-strength adhesive. Through holes 10 are evenly spaced along the length of the clamping plate 2. The through holes 10 can reduce the weight of the clamping plate 2 and also play a role in heat dissipation to some extent.

[0030] Reference Figure 1 and Figure 2 A rubber layer 11 is provided on the side where the clamping plate 2 abuts against the clamping body 3. The rubber layer 11 is elastic and can buffer the vibration and impact between the clamping plate 2 and the clamping body 3, and avoid wear on the contact surface. The rubber layer 11 can be fixed to the clamping plate 2 by adhesive.

[0031] Reference Figure 1 and Figure 3A first receiving groove 4 is provided at the lower end of the clamping body 3, and a first arc-shaped block 8 is integrally formed at the upper end of the clamping body 3, near the clamping plate 2. The arc-shaped structure of the first arc-shaped block 8 can distribute the stress applied to the clamping plate 2 more evenly. This reduces the risk of fatigue cracks in the clamping body 3, thereby improving the durability of the clamping body 3 and the reliability of the entire device, and reducing the need for frequent maintenance and replacement due to component damage. The shape of the first receiving groove 4 matches the shape of the rail foot of the rail 1. The clamping bodies 3 are arranged in pairs and are located on both sides of the rail 1, and are clamped and fixed to the rail 1 by the connecting assembly 5. The lower end of the clamping body 3 is fixed to the rail foot of the rail 1 by the first receiving groove 4, and the upper end of the clamping body 3 is fixed to the clamping plate 2 by the first arc-shaped block 8.

[0032] Reference Figures 1 to 3 A limiting block 9 is integrally formed on the side of the clamping plate 2 near the clamping body 3. The limiting block 9 works in conjunction with the first arc-shaped block 8, and the side of the limiting block 9 near the first arc-shaped block 8 is arc-shaped. The pair of clamping bodies 3 are fixed to both sides of the rail 1 using the connecting assembly 5. At this time, the limiting block 9 is located above the first arc-shaped block 8, and when the rail 1 vibrates, the limiting block 9 can resist the first arc-shaped block 8, thereby preventing the clamping body 3 from detaching from the rail foot of the rail 1.

[0033] Reference Figure 1 and Figure 4 The connecting assembly 5 includes a double-ended bolt 51 and two nuts 52. The double-ended bolt 51 is typically made of high-strength steel and has threads at both ends. The double-ended bolt 51 passes through holes in a pair of clamps 3 located on both sides of the rail 1, and the two nuts 52 are threaded onto both ends of the double-ended bolt 51. By tightening the nuts 52 at both ends with a torque wrench, the pair of clamps 3 are abutted and fixed onto the rail 1.

[0034] Reference Figure 1 and Figure 4 The reinforcing structure 6 includes a reinforcing block 61, a second receiving groove 62, and a second arc-shaped head 63. The reinforcing block 61 is integrally formed on the clamping body 3. The second receiving groove 62 is formed on the reinforcing block 61 to cooperate with the rail foot of the rail 1, further enhancing the fixing effect on the rail foot. The second arc-shaped head 63 is integrally formed on the side of the reinforcing block 61 near the clamping plate 2. The paired reinforcing blocks 61 are also connected and fixed to the rail 1 via the connecting assembly 5, increasing the contact area between the clamping plate 2 and the clamping body 3 and improving the reinforcement effect.

[0035] Reference Figure 4 and Figure 5The anti-loosening plate 7 includes a first plate 71 and two second plates 72. The first plate 71 rotates on the side of the clamping body 3 away from the clamping plate 2, typically connected by a pin or similar means. Both second plates 72 are integrally formed on the first plate 71, and the first plate 71 and the two second plates 72 form a limiting space. This limiting space is used to hold the nut 52 in place to prevent it from loosening. When the nut 52 is tightened, the first plate 71 is lowered, causing the limiting space to hold the nut 52 in place, thus preventing the nut 52 from loosening under vibration or other conditions.

[0036] The implementation principle of the rail non-destructive reinforcement clamping device in this application embodiment is as follows: High-strength adhesive is evenly applied to the clamping plate 2 to fix it to the rail web of the rail 1. Pairs of clamping bodies 3, under the action of the first receiving groove 4 and the connecting assembly 5, clamp and fix the first arc-shaped block 8 to the clamping plate 2. The reinforcement structure 6 further enhances the clamping strength between the clamping bodies 3 and the clamping plate 2. An anti-loosening plate 7 is used to hold the nut 52, thereby preventing the nut 52 from loosening under vibration or other conditions, ensuring the stability and reliability of the entire clamping device during long-term use.
