Description

Technical Field

[0001] This utility model relates to the field of rail reinforcement technology, specifically to a rail reinforcement clamp assembly. Background Technology

[0002] As part of the track circuit, various electrical signals need to be conducted through the rails as conductors. When a complete rail or a rail with a welded joint is damaged (but not completely broken), it is reinforced using a rail fastening safety device. Because this device is insulated from the rail, when the rail is completely broken, the track circuit signals transmitted through the rail are interrupted, allowing the monitoring system to detect the problem in time and handle it promptly.

[0003] For example, patent CN211872428U discloses a rail weld reinforcement clamp. The clamp includes a base, a top slot, a clearance structure, through holes, a reinforcing boss, a bonding structure, and a load-bearing curved surface. The side of the clamp that contacts the rail has the load-bearing curved surface, the bonding structure, and the clearance structure. Specifically, the bonding structure uses several layers of fiberglass cloth coated with adhesive on both sides, stacked and aligned together. A layer of PET film is pasted on one side of the fiberglass cloth, thus ensuring connection strength and providing an immediate warning to the signaling department when a break occurs at a damaged section of the rail, effectively protecting and monitoring track safety.

[0004] However, the insulation layer in this patent is bonded to the substrate of the plywood. When transported in harsh environments, the bonded structure is prone to wear and failure, requiring the plywood to be re-coated. The re-coating process is complex and time-consuming. Utility Model Content

[0005] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a rail reinforcement clamp assembly. This solves the technical problem that in the prior art, the insulation layer is glued to the clamp substrate, which easily leads to wear and failure of the glued structure when transported in harsh environments. This requires the clamp to be re-glued, and the gluing operation is complicated and time-consuming.

[0006] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: This utility model provides a rail reinforcement clamp assembly, comprising: Clamping plates are used to install on the side ends of steel rails; An insulating structure includes multiple insulating plates disposed between the clamping plate and the rail, arranged sequentially along the rail's laying direction, for isolating the clamping plate from the rail; and The mounting structure includes multiple limiting parts and multiple mounting parts. The multiple limiting parts are respectively disposed on multiple insulating plates, and the multiple mounting parts are disposed on the clamping plate and respectively cooperate with the multiple limiting parts, so that each insulating plate can be detachably mounted on the clamping plate.

[0007] In some embodiments, each of the mounting portions can also cooperate with a mating portion provided on the rail to detachably mount the clamp to the rail.

[0008] In some embodiments, the limiting part is a limiting hole provided in the insulating plate, and the clamping plate is provided with a mounting hole corresponding to the limiting hole; The mounting part includes mounting bolts and mounting nuts. The mounting bolts pass through the mounting holes and the limiting holes in sequence, and also pass through the mating holes located on the rail. The mounting nuts are screwed onto the mounting bolts.

[0009] In some embodiments, each of the insulating plates is provided with an insulating cylinder facing the mounting hole and a mating insulating cylinder facing the mating hole, the insulating cylinder extending into the mounting hole and the mating insulating cylinder extending into the mating hole; The mounting bolts are sequentially passed through the mounting insulating cylinder and the mating insulating cylinder.

[0010] In some embodiments, the clamping plates and the insulating structure are provided in two sets, the two sets of clamping plates are used to be placed on opposite sides of the rail, and the two sets of insulating plates are respectively placed between the two sets of clamping plates and the rail; The mounting bolt passes through one set of mounting holes and extends out from another set of mounting holes, and the mounting nut is screwed onto the end of the mounting bolt that extends out of the other mounting hole.

[0011] In some embodiments, N insulating plates are provided, and each insulating plate has a slot on both sides of its arrangement direction. The opening ends of any two adjacent slots abut and communicate with each other to form (N-1) installation spaces. The insulation structure further includes (N-1) sealed insulation plates, which are respectively placed in (N-1) installation spaces, where N is an integer greater than or equal to 2.

[0012] In some embodiments, the insulating plate includes an insulating substrate and a channel steel, wherein the channel steel is embedded in the insulating substrate.

[0013] In some embodiments, two adjacent channel steels are spaced apart along the layout direction of the rail.

[0014] In some embodiments, the insulating board is an epoxy resin glass fiber insulating board.

[0015] In some embodiments, at least one of the insulating plates includes a flexible segment and two rigid segments, the two rigid segments being spaced apart along the arrangement direction of the rails, the flexible segment being located between the two rigid segments and connecting the two rigid segments.

[0016] Compared with existing technologies, the rail reinforcement clamp assembly provided by this utility model allows for the detachable installation of each insulating plate onto the clamp through the cooperation of the mounting part and the limiting part. This enables the insulating plates to be removed from the clamp and stored centrally during transportation, reducing the risk of damage. When the clamp and insulating plates are transported to the damaged area of ​​the rail, multiple insulating plates are then sequentially installed between the clamp and the rail along the rail's layout direction. This ensures sufficient connection strength at the damaged rail location while maintaining insulation in the event of a rail breakage, preventing interruption of track circuit signals transmitted through the rail and facilitating timely detection of problems by the monitoring system. Furthermore, even if individual insulating plates are damaged, replacement plates can be quickly replaced at the corresponding positions on the clamp, making the operation relatively convenient, time-efficient, and practical.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] To address the technical problem in existing technologies where the insulation layer is glued to the clamping plate substrate, which easily leads to wear and failure of the bonded structure during transportation in harsh environments, requiring the clamping plate to be re-glued, a complex and time-consuming process, this utility model provides a rail reinforcement clamping plate assembly. This assembly reduces the risk of insulation plate damage, and even if individual insulation plates are damaged, replacement insulation plates can be promptly replaced at the corresponding positions on the clamping plate. The operation is relatively convenient, time-saving, and practical.

[0021] Please see Figures 1 to 3 , Figures 1 to 3 This is a schematic diagram of the rail reinforcement clamp assembly in one embodiment of the present invention. The rail reinforcement clamp assembly includes a clamp 1, an insulation structure, and an installation structure. The clamp 1 is used to install on the side end of the rail 5. The insulation structure includes multiple insulation plates 2, which are disposed between the clamp 1 and the rail 5 and arranged sequentially along the laying direction of the rail 5 to isolate the clamp 1 from the rail 5. The installation structure includes multiple limiting parts 3 and multiple mounting parts 4. The multiple limiting parts 3 are respectively disposed on the multiple insulation plates 2, and the multiple mounting parts 4 are disposed on the clamp 1 and cooperate with the multiple limiting parts 3 respectively, so that each insulation plate 2 is detachably installed on the clamp 1. Specifically, the clamp 1 has an installation end face 11 that abuts against the rail 5, and the insulation plate 2 is disposed on the installation end face 11.

[0022] In the rail reinforcement clamp assembly provided by this utility model, the mounting part 4 and the limiting part 3 cooperate to allow each insulating plate 2 to be detachably installed on the clamp 1. This allows the insulating plates 2 to be removed from the clamp 1 and stored together during transportation, reducing the risk of damage to the insulating plates 2. When the clamp 1 and insulating plates 2 are transported to the damaged area of ​​the rail 5, multiple insulating plates 2 are then sequentially installed on the mounting end face 11 of the clamp 1 along the laying direction of the rail 5. This ensures the connection strength at the damaged area of ​​the rail 5 is met while maintaining insulation in the event of a breakage at the damaged area, preventing the interruption of track circuit signals transmitted through the rail 5 and facilitating timely detection of problems by the monitoring system. Furthermore, even if individual insulating plates 2 are damaged, replacement insulating plates 2 can be promptly replaced at the corresponding position on the clamp 1. The operation is relatively convenient, time-saving, and practical.

[0023] In one embodiment, each mounting part 4 can also cooperate with a mating part provided on the rail 5 to detachably mount the clamp 1 on the rail 5.

[0024] In this embodiment, the mounting part 4 cooperates with the limiting part 3 on the insulating plate 2 and the mating part on the rail 5 to realize the detachable installation of the insulating plate 2 on the clamping plate 1, and at the same time, the clamping plate 1 can also be detachably installed on the rail 5, reducing the number of parts and making the overall structure more compact and reducing the space occupied.

[0025] It should be noted that the arrangement of the mounting part 4 and the limiting part 3 is not limited, as long as it enables the detachable connection of the insulating plate 2 to the clamping plate 1 and the detachable connection of the clamping plate 1 to the rail 5. In one embodiment, the limiting part 3 is a through hole penetrating the insulating plate 2, and the mounting part 4 is a mounting buckle provided on the clamping plate 1, which passes through the through hole and is fastened in the slot 2a of the rail 5. In another embodiment, the mounting part 4 is a pin provided on the clamping plate 1, which passes through the through hole on the insulating plate 2 and the through hole on the rail 5 in sequence, and a locking pin is provided at the end of the pin that passes through the through hole on the rail 5.

[0026] In one embodiment, please refer to Figures 3 to 6 The limiting part 3 is a limiting hole 3a provided on the insulating plate 2, and the clamping plate 1 is provided with a mounting hole 1a corresponding to the limiting hole 3a; the mounting part 4 includes a mounting bolt 41 and a mounting nut 42. The mounting bolt 41 passes through the mounting hole 1a and the limiting hole 3a in sequence, and passes through the mating hole 5a located on the rail 5. The mounting nut 42 is screwed onto the mounting bolt 41.

[0027] In this embodiment, the limiting part 3 is set as the limiting hole 3a on the insulating plate 2, and the mounting hole 1a is set on the clamping plate 1. The mating part is set as the mating hole 5a on the rail 5. The mounting part 4 is set as the mounting bolt 41 and the mounting nut 42, so that the mounting nut 42 passes through the mounting hole 1a, the limiting hole 3a, and the mating hole 5a in sequence, and is tightened by the mounting nut 42. The structure is stable and reliable, and the operation is relatively convenient. It should be noted that, in one embodiment, the inner walls of the mounting hole 1a and the mating hole 5a are filled with an insulating layer.

[0028] In one embodiment, each insulating plate 2 is provided with an insulating cylinder 21 facing the mounting hole 1a and a mating insulating cylinder 22 facing the mating hole 5a. The insulating cylinder 21 extends into the mounting hole 1a and the mating insulating cylinder 22 extends into the mating hole 5a. The mounting bolt 41 passes through the insulating cylinder 21 and the mating insulating cylinder 22 in sequence.

[0029] In this embodiment, an insulating cylinder 21 is installed on the insulating plate 2 corresponding to the mounting hole 1a, and a mating insulating cylinder 22 is installed on the mating hole 5a. On the one hand, this can guide and position the installation of the insulating plate 2, improving the ease of assembly; on the other hand, it can effectively insulate the mounting bolt 41 from the rail 5 and the clamping plate 1.

[0030] In one embodiment, please refer to Figure 4 An insulating sleeve 7 is set separately. The insulating sleeve 7 passes through the limiting hole 3a of the insulating plate 2, the mating hole 5a of the rail 5 and the limiting hole 3a of another insulating plate 2 in sequence. Then, the mounting bolt 41 is passed through the insulating sleeve 7 and the mounting nut 42 is screwed on.

[0031] In one embodiment, the clamping plate 1 and the insulating structure are provided in two sets. The two sets of clamping plates 1 are used to be placed on opposite sides of the rail 5. The two sets of insulating plates 2 are respectively placed between the two sets of clamping plates 1 and the rail 5. The mounting bolt 41 passes through the mounting hole 1a of the corresponding set and extends out from the mounting hole 1a of the other set. The mounting nut 42 is screwed onto the end of the mounting bolt 41 that extends out of the other mounting hole 1a.

[0032] In this embodiment, two sets of clamping plates 1 and insulation structures are set on both sides of the rail 5, which further enhances the fastening effect on the damaged parts of the rail 5 while ensuring the normal monitoring function, thereby improving the strength of the damaged parts of the rail 5.

[0033] In one embodiment, please refer to Figures 7 to 9There are N insulating plates 2, and each insulating plate 2 has a slot 2a on both sides of its arrangement direction. The opening ends of any two adjacent slots 2a abut and connect to form (N-1) installation spaces. The insulating structure also includes (N-1) sealing insulating plates 6, and the (N-1) sealing insulating plates 6 are respectively placed in (N-1) installation spaces, where N is an integer greater than or equal to 2.

[0034] In this embodiment, a sealing insulation plate 6 is also provided between two adjacent insulation plates 2, so that an overlapping area is formed between the two insulation plates 2 and the sealing insulation plate 6, preventing the steel rail 5 from being conducted through the gap between the clamping plate 1 and the insulation plate 2, thereby improving the insulation performance. Specifically, in this solution, the insulation plate 2 is an epoxy resin glass fiber insulation plate 2, the Young's modulus of the epoxy resin glass fiber is 4500MPa, and the Poisson's ratio is 0.19.

[0035] In one embodiment, the insulating plate 2 includes an insulating substrate and a channel steel, with the channel steel embedded in the insulating substrate.

[0036] In this embodiment, the insulating plate 2 is configured as an insulating substrate and a channel steel, which not only ensures the insulation performance of the insulating plate 2, but also increases the strength of the insulating plate 2. Thus, when the insulating plate 2 is placed between the clamping plate 1 and the rail 5, it can disperse some of the force, thereby improving the safety of the damaged part of the rail 5.

[0037] In one embodiment, two adjacent channel steels are spaced apart along the laying direction of the rail 5.

[0038] In this embodiment, any two adjacent channel steels are spaced apart to reduce the possibility of accidental conduction of the rail 5 due to the connection of the channel steels, and further improve the insulation performance of the component.

[0039] In one embodiment, at least one insulating plate 2 includes a flexible segment 23 and two rigid segments 24, the two rigid segments 24 being spaced apart along the arrangement direction of the rail 5, the flexible segment 23 being located between the two rigid segments 24 and connecting the two rigid segments 24.

[0040] In this embodiment, a flexible section 23 is provided on the insulating plate 2 to fit the joint weld of the rail 5 and the clearance groove of the clamping plate 1, which is practical. It should be noted that in one embodiment, the insulating substrate can be made of a flexible material, and two channel steel sections can be spaced apart to form a rigid section 24, with the flexible section 23 located between the two channel steel sections. It should be understood that the insulating substrate covers the outer periphery of the channel steel, ensuring that the channel steel is not exposed. Furthermore, it should be noted that in this embodiment, the flexible section 23 is pressed against the side wall of the clearance groove of the clamping plate 1 and the weld of the rail 5. Each of the two rigid sections 24 is provided with a limiting hole 3a, and the clamping plate 1 and the rail 5 are respectively provided with holes corresponding to the limiting holes 3a of the rigid sections 24 for the corresponding mounting bolts 41 to pass through.

[0041] To better understand this utility model, the following is combined with... Figures 1 to 9 The technical solution of this utility model is described in detail below: The clamping plate 1 is forged from 40Cr material and, after heat treatment, achieves a tensile strength of 900MPa. To effectively provide insulation, the insulation resistance of the installed safety device must meet the following requirements: greater than 200MΩ in a dry state and greater than 3000Ω in a damp state. This improves the connection strength of the rail 5 when the clamping plate 1 is fixed to the side of the rail 5 using mounting bolts 41. Furthermore, when the rail 5 is damaged or the welded joint is not completely severed, the electrical signal at the damaged point remains conductive. When the damage rapidly expands to complete severance, the electrical signal will disconnect, allowing monitoring personnel to promptly detect and address the problem.

[0042] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
