Description

Technical Field

[0001] This application relates to the field of lead wire installation technology, and more specifically, to a railway signal lead wire fixing clamp. Background Technology

[0002] In railway track transportation systems, the lead wire is a key component connecting various signaling devices, and its fixation directly affects the reliability and safety of the entire system. Common methods for fixing lead wires involve simple cable ties or ordinary clamps for limiting installation, which are easily loosened or even detached due to vibration, temperature changes, and other factors. Some complex clamp structures are inconvenient to install, unable to quickly and effectively adapt to the tightening requirements under different working conditions, and lack effective anti-loosening design and precise positioning functions. Long-term use may lead to displacement, potentially causing excessive compression and damage to the cable insulation layer, affecting signal transmission quality. Therefore, we propose a railway signal lead wire fixing clamp. Utility Model Content

[0003] 1. Technical problems to be solved

[0004] The purpose of this application is to provide a railway signal lead wire fixing clamp, which solves the technical problems mentioned in the background art. It realizes that by using the studs and connectors at both ends of the mounting base to cooperate, the clamp can be firmly fixed and installed on the hot rail, effectively resisting external vibration interference and preventing loosening caused by strong shaking caused by passing trains. By rotating the threaded rod, the two sets of L-shaped clamps are driven to move like crank connecting rods, so that the clamping force of the L-shaped clamps and L-shaped plates on the lead wire can be adjusted according to actual needs. This ensures that the lead wire is stably installed and avoids slippage, while avoiding excessive compression and damage to the cable insulation layer. The ingenious design enables rapid assembly and disassembly.

[0005] 2. Technical Solution

[0006] This application provides a railway signal lead wire fixing clamp, comprising: a mounting base, on which two clamp seats are fixedly sleeved, each clamp seat including an L-shaped seat and an elongated tube, the elongated tube being fixedly sleeved with the mounting base and used for threading the lead wire; studs fixedly provided at both ends of the mounting base, and a connector detachably connected to the mounting base via the studs for limiting its installation on the hot rail; a threaded rod rotatably mounted on the mounting base, and a clamping mechanism mounted on the L-shaped seat; rotating the threaded rod transmits power to the clamping mechanism, which in turn clamps the lead wire in conjunction with the L-shaped seat.

[0007] By adopting the above technical solution, the mounting base serves as the main installation structure. Two clamping seats are fixedly fitted onto the mounting base. Each clamping seat consists of an L-shaped seat and a long tube. The long tube is used to thread and guide the lead wire into the correct path, ensuring that part of the lead wire's end rests on the L-shaped seat. By rotating the threaded rod, power is transmitted to the clamping mechanism, thereby effectively clamping the lead wire. The operation is simple and intuitive, and the clamping force can be flexibly adjusted according to different application scenarios. The studs at both ends of the mounting base are detachable connectors for connecting to the track bracket, allowing adjustment of the installation position and height of the mounting base and lead wire, improving installation flexibility and facilitating later maintenance.

[0008] Optionally, the connector includes an L-shaped plate and a connecting plate, which are fixedly connected, and the L-shaped plate has two mounting holes.

[0009] By adopting the above technical solution, two mounting holes are opened on the L-shaped plate, and the L-shaped plate can be fixed to the track bracket by bolt structure. The L-shaped plate and the connecting plate are fixedly connected to form a connector to provide stable support for the mounting seat.

[0010] Optionally, both ends of the connecting plate are provided with through holes that match the studs, and the studs are threaded with an upper lock nut and a lower lock nut respectively on the upper and lower surfaces of the connecting plate.

[0011] By adopting the above technical solution, when it is necessary to adjust the installation height of the mounting base, it is only necessary to adjust the upper and lower locking nuts on the upper and lower surfaces of the connecting plate. The mounting base can be moved upward by loosening the lower locking nut and tightening the upper locking nut.

[0012] Optionally, the clamping mechanism includes a rectangular block rotatably connected to a threaded rod. The rectangular block is rotatably sleeved with a first rotating shaft. Each end of the first rotating shaft is rotatably connected to a first rotating plate. Each L-shaped plate has a slot. The ends of the first rotating shaft movably pass through the slots on the corresponding L-shaped plates. Two rotating rods are fixedly mounted on the L-shaped plates. Each rotating rod is rotatably connected to an L-shaped clamping wall. The two L-shaped clamping walls on the L-shaped plates are arranged in parallel. A second rotating shaft is rotatably connected between every two L-shaped clamping walls. The two second rotating shafts are arranged in parallel. Each end of the two second rotating shafts is rotatably connected to a strip plate. The upper end of the first rotating plate is rotatably sleeved with the adjacent second rotating shaft.

[0013] By adopting the above technical solution, when the threaded rod rotates, it drives the first rotating shaft and the first rotating plate on the first rotating shaft to rotate together. The strip groove on the L-shaped seat provides a guiding function for the first rotating shaft, restricting the first rotating shaft to move only along the direction of the strip groove. On the L-shaped seat, the two sets of L-shaped clamping walls can achieve crank-connecting rod movement under the cooperation of the second rotating shaft and the strip plate, so that the upper end of the first rotating plate transmits power to the adjacent second rotating shaft, so that the L-shaped clamping walls rotate around the rotating rod as the center. The L-shaped seat can be used to clamp the lead wire.

[0014] Optionally, the two second rotating shafts and the two first rotating plates form a rectangular frame structure, and the L-shaped clamping walls are respectively installed at one corner of the rectangular frame structure.

[0015] By adopting the above technical solution, the two second rotating shafts and the two first rotating plates together form a closed rectangular frame structure, which allows the two sets of L-shaped clamping walls to achieve crank-connecting rod movement through the cooperation and connection of the second rotating shafts and strip plates.

[0016] Optionally, a U-shaped through groove is provided inside the elongated tube, and a lead wire is movably passed through the U-shaped through groove. An arc-shaped groove is provided on the L-shaped seat, and an arc groove is provided on the L-shaped clamping wall. The lead wire is clamped and installed between the L-shaped seat and the L-shaped clamping wall.

[0017] By adopting the above technical solution, the U-shaped through groove in the long tube mainly serves as a guide to guide the lead wire to enter smoothly, while the arc-shaped groove in the L-shaped seat provides installation space for the lead wire, and together with the L-shaped clamping wall, it achieves the purpose of clamping the lead wire.

By rotating the threaded rod, the two sets of L-shaped clamping walls are driven to move like crank connecting rods, so that the clamping force of the L-shaped clamping walls and L-shaped plates on the lead wire can be adjusted according to actual needs. This ensures that the lead wire is stably installed and avoids slippage, while avoiding excessive compression that could damage the cable insulation layer. The ingenious design allows for quick assembly and disassembly.

[0022] 3. The arc-shaped groove on the L-shaped seat works in conjunction with the U-shaped through groove of the long tube to wrap the lead wire, forming a protective barrier and reducing the risk of wear. Attached Figure Description

[0028] The present application will be further described in detail below with reference to the accompanying drawings.

[0029] Reference Figures 1 to 4This application provides a railway signal lead wire fixing clamp, comprising: a mounting base 1, on which two clamp seats 3 are fixedly sleeved, each clamp seat 3 including an L-shaped seat 31 and an elongated tube 32. The elongated tube 32 is fixedly sleeved with the mounting base 1 and is used to pass through the lead wire. Both ends of the mounting base 1 are fixedly provided with studs 11. A connector 2 is detachably connected to the mounting base 1 via the studs 11 for limiting its installation on the hot rail. A threaded rod 4 is rotatably mounted on the mounting base 1. A clamping mechanism 5 is mounted on the L-shaped seat 31. Rotating the threaded rod 4 transmits power to the clamping mechanism 5, which, in conjunction with the L-shaped seat 31, clamps the lead wire. The mounting base 1 serves as... The main installation structure has two clamp seats 3 fixedly fitted on the mounting base 1. Each clamp seat 3 consists of an L-shaped seat 31 and a long tube 32. The long tube 32 is used to thread and guide the lead wire into the correct path, so that part of the lead wire end rests on the L-shaped seat 31. By rotating the threaded rod 4, power is transmitted to the clamping mechanism 5, thereby achieving effective clamping of the lead wire. The operation is simple and intuitive, and the clamping force can be flexibly adjusted according to different application scenarios. The studs 11 at both ends of the mounting base 1 are detachable connectors 2 for connecting with the track bracket, which can adjust the installation position and height of the mounting base 1 and the lead wire, improve installation flexibility, and facilitate later maintenance.

[0030] Reference Figure 2 and Figure 3 The connector 2 includes an L-shaped plate 21 and a connecting plate 22, which are fixedly connected. The L-shaped plate 21 has two mounting holes 211, which can be used to limit and fix the L-shaped plate 21 to the track bracket using bolts. The L-shaped plate 21 and the connecting plate 22 are fixedly connected to form the connector 2, which provides stable support for the mounting base 1.

[0031] Reference Figure 2 and Figure 3 Both ends of the connecting plate 22 are provided with through holes that match the studs 11. The studs 11 are threaded with upper lock nuts 13 and lower lock nuts 12 on the upper and lower surfaces of the connecting plate 22, respectively. When it is necessary to adjust the installation height of the mounting base 1, it is only necessary to adjust the upper lock nuts 13 and lower lock nuts 12 on the upper and lower surfaces of the connecting plate 22. The mounting base 1 can be moved upward by loosening the lower lock nut 12 and tightening the upper lock nut 13.

[0032] Reference Figure 2 and Figure 4The clamping mechanism 5 includes a rectangular block 51, which is rotatably connected to the threaded rod 4. A first rotating shaft 52 is rotatably sleeved on the rectangular block 51. A first rotating plate 53 is rotatably connected to both ends of the first rotating shaft 52. A strip-shaped groove 313 is provided on each of the L-shaped plates 21. The two ends of the first rotating shaft 52 movably pass through the corresponding strip-shaped grooves 313 on the L-shaped plates 21. Two rotating rods 312 are fixedly mounted on the L-shaped plates 21. Each rotating rod 312 is rotatably connected to an L-shaped clamping wall 54. The two L-shaped clamping walls 54 on the L-shaped plates 21 are arranged in parallel. A second rotating shaft 55 is rotatably connected between each pair of L-shaped clamping walls 54, and the two second rotating shafts 55 are also arranged in parallel. Each end of the two second rotating shafts 55 is rotatably connected to a strip-shaped groove 53. The upper end of the first rotating plate 53 is rotatably sleeved with the adjacent second rotating shaft 55. When the threaded rod 4 rotates, it drives the first rotating shaft 52 and the first rotating plate 53 on the first rotating shaft 52 to rotate together. The strip groove 313 on the L-shaped seat 31 provides a guiding function for the first rotating shaft 52, restricting the first rotating shaft 52 to move only along the direction of the strip groove 313. On the L-shaped seat 31, the two sets of L-shaped clamping walls 54 can realize the crank-connecting rod movement under the cooperation of the second rotating shaft 55 and the strip plate 56, so that the upper end of the first rotating plate 53 transmits power to the adjacent second rotating shaft 55, so that the L-shaped clamping wall 54 rotates around the rotating rod 312 as the center, and can cooperate with the L-shaped seat 31 to only clamp the lead wire.

[0033] Reference Figure 1 and Figure 2 Two second rotating shafts 55 and two first rotating plates 53 form a rectangular frame structure. L-shaped clamping walls 54 are respectively installed at one corner of the rectangular frame structure. The two second rotating shafts 55 and two first rotating plates 53 together form a closed rectangular frame structure, which allows the two sets of L-shaped clamping walls 54 to achieve crank-connecting rod movement under the cooperation of the second rotating shafts 55 and the strip plate 56.

[0034] Reference Figure 1 and Figure 2 The elongated tube 32 has a U-shaped through groove 321, through which the lead wire is movably passed. The L-shaped seat 31 has an arc groove 311, and the L-shaped clamping wall 54 has an arc groove 541. The lead wire is clamped and installed between the L-shaped seat 31 and the L-shaped clamping wall 54. The U-shaped through groove 321 in the elongated tube 32 mainly serves as a guide to guide the lead wire to enter smoothly. The arc groove 311 in the L-shaped seat 31 provides installation space for the lead wire and works with the L-shaped clamping wall 54 to achieve the purpose of clamping the lead wire.

[0035] Working principle: When it is necessary to fix a section of railway signal lead wire, firstly, the lead wire is passed through the U-shaped through groove 321 in the elongated tube 32, so that the end of the lead wire passes over the L-shaped seat 31, and the part of the lead wire near the end is placed in the clamping space formed by the L-shaped seat 31 and the L-shaped clamping wall 54. Then, the threaded rod 4 is rotated, which drives the first rotating shaft 52 connected to it and the first rotating plates 53 at both ends of the first rotating shaft 52 to move. Then, the power is transmitted to the strip plate 56 through the second rotating shaft 55, so that the two sets of L-shaped clamping walls 54 realize the crank-connecting rod movement. Finally, the lead wire is tightly clamped by the L-shaped clamping wall 54 with the arc groove 541. The L-shaped plate 21 is pressed against the arc groove 311 of the L-shaped seat 31, and then the L-shaped plate 21 is fixed to the hot rail by bolt structure, so that the overall clamp can stably limit the railway signal lead wire. Since the stud 11 is located on the upper and lower surfaces of the connecting plate 22, the upper lock nut 13 and the lower lock nut 12 are respectively provided. The installation height of the mounting seat 1 can be adjusted by the upper lock nut 13 and the lower lock nut 12, so that the railway signal lead wire is limited to the designated position. Even if it is subjected to a large external force, it will not be displaced. If the lead wire needs to be replaced or repaired, the clamping force can be released by simply rotating the threaded rod 4 in the opposite direction, and the old wire can be easily taken out and the new wire can be inserted.
