Description

Technical Field

[0001] The present invention belongs to the technical field of electric power construction, and specifically relates to a strain clamp with a stable clamping structure. Background Art

[0002] A strain clamp is a device used in power lines or communication lines, mainly for fixing, supporting, and tensioning conductors. The strain clamp can withstand the strong tension generated by the conductor tension, ensuring the stability and safety of the line. It can fix the conductor on a pole or tower, provide sufficient support, prevent the conductor from shifting due to wind or other external forces, and prevent the conductor from sliding in the clamp, thereby maintaining the tension state and position of the conductor. When erecting high-voltage power lines or communication lines, the strain clamp is a very important accessory to ensure the reliability and safety of the line operation.

[0003] A Chinese patent with the publication number CN104466856A discloses a wedge-shaped aluminum strain clamp, which includes a conductive body and a conductive clamping core. An accommodation cavity is provided inside the conductive body, and a pressing device is provided inside the accommodation cavity. A cable main conductor is clamped between the inner surface of the conductive body and one side of the conductive clamping core, and a cable branch conductor is clamped between the other side of the conductive clamping core and one side of the pressing device. The pressing device is used to apply a squeezing force to the clamped cable main conductor and cable branch conductor. The present invention is convenient for installation, has a simple structure. Installers do not need to work at high altitudes. They can use a special tool to stand on the ground and connect the cable main conductor and cable branch conductor through the wedge-shaped aluminum strain clamp, saving the installation time of installers and eliminating the safety hazards of installers working at high altitudes. The present invention also has the functions of simple operation, easy disassembly, and stable connection performance.

[0004] However, the current strain clamp has an unsatisfactory clamping and positioning effect when fixing cables, which easily causes the cable position to slide and the clamping to be unstable. During the fixing process, if the cable position slides, it is necessary to readjust the tension, which brings certain limitations.

[0005] Therefore, the present invention provides a strain clamp with a stable clamping structure. Summary of the Invention

[0006] In order to make up for the deficiencies of the prior art and solve the technical problem of inconvenient positioning and clamping of cables, the present invention proposes a strain clamp with a stable clamping structure.

[0007] The technical solution adopted by the present invention to solve its technical problems is as follows: A strain clamp with a stable clamping structure according to the present invention includes a frame. A conical groove is arranged inside the frame. A wire clamping component is arranged inside the conical groove. A square frame is fixedly installed at one end of the frame. A through cylinder is arranged inside the square frame. A positioning component is arranged inside the square frame. A connecting block is fixedly installed on the frame. A hole is arranged inside the connecting block. A support rod passes through the hole. A support plate is arranged on the support rod. A traction component for pulling the square frame is arranged on the support plate. A guiding component is arranged inside the conical groove. A limiting component is arranged on the support rod. A pulling block is fixedly installed on the support rod.

[0008] By adopting the above technical solution, after one end of the cable to be fixed passes through the through cylinder, and the cable is sorted out, the traction component can drive the positioning component to move. The positioning component can limit the cable passing through the inside of the through cylinder. Then, the wire clamping component clamps and limits the cable, thereby achieving the purpose of stably clamping the cable and effectively avoiding the loosening of the cable. The pulling block is connected by a steel wire rope, and the other end of the steel wire rope is fixedly connected to a fixed point, thereby positioning and installing one end of the cable. When adjusting the tension of the cable, through the movement of the traction component, the square frame can be pulled to move. The movement of the square frame can drive the cable to move and at the same time drive the frame to move synchronously, thereby adjusting the pulling force of the cable and improving the flexibility of the strain clamp with a stable clamping structure.

[0009] Preferably, the wire clamping component includes a conical block and an arc groove. The conical block is arranged inside the conical groove. The arc groove is arranged on the conical block.

[0010] By adopting the above technical solution, after one end of the cable is moved into the arc groove, then the conical block is moved, and the conical block slides into the conical groove, thereby pressing on the outside of the conical block and making the conical block close inward, thereby fixedly clamping the cable.

[0011] Preferably, the guiding component includes a guiding groove and a guiding block. The guiding groove is arranged inside the frame and is communicated with the conical groove. The guiding block passes through the guiding groove and is fixedly connected to the conical block.

[0012] By adopting the above technical solution, when the conical block moves, the cooperation of the guiding groove and the guiding block will guide the conical block to move smoothly.

[0014] By adopting the above technical solution, when the support rod is fixedly connected to the frame, after one end of the threaded section passes through the hole, after the positioning nut is threadedly connected to the threaded section, the positioning nut is rotated. After the positioning nut is threadedly connected to the threaded section, pressure is applied to the connecting block, and then the frame can be connected.

[0015] Preferably, the positioning assembly includes a load-bearing block, a cylinder, a limiting block, a restraint belt, a pull rod and a through hole. The load-bearing block is fixedly installed inside the square frame. The cylinder is arranged inside the load-bearing block.

The pull rod is arranged inside the cylinder, and one end of the pull rod is fixedly connected to the limiting block. The through hole is arranged inside the pull rod.

[0016] By adopting the above technical solution, when one end of the traction rope is fixedly connected to the through hole, when the traction rope is wound up, the pull rod will be driven to slide inside the cylinder through the through hole. The movement of the pull rod will drive the movement of the limiting block. The downward movement of the limiting block will drive the movement of the restraint belt. The downward movement of the restraint belt contacts the top of the cable arranged inside the cylinder, and then the cable can be limited, and then the cable can be clamped by limiting, improving the stability of the cable fixation and avoiding accidental loosening of the cable.

[0017] Preferably, a positioning block is fixedly installed on the support plate. A positioning hole is arranged inside the positioning block. A support cylinder corresponding to the support rod is arranged inside the support plate, and the support rod penetrates through the support cylinder.

[0018] By adopting the above technical solution, by fixing the support frame at the installation location and connecting it to the positioning block, and then using bolts to cooperate through the positioning hole, the support plate can be fixedly installed.

[0019] Preferably, the traction assembly includes a storage box, a wire arranging ring, a winding mechanism and a limiting mechanism. The storage box is fixedly installed at the bottom of the support plate. The wire arranging ring is fixedly installed inside the storage box. The winding mechanism is arranged inside the storage box. The limiting mechanism is arranged inside the storage box.

[0020] By adopting the above technical solution, the traction rope is guided and limited by the wire arranging ring. The winding mechanism can wind up the traction rope when it works. When the traction rope moves, it will pull the square frame to move. After the square frame is moved to the predetermined position, the limiting mechanism can position the winding mechanism, and then position the square frame.

[0021] Preferably, the winding mechanism includes a winding wheel, a rotating shaft and a traction rope. The winding wheel is arranged inside the storage box. The rotating shaft is rotatably arranged inside the storage box, and one end of the rotating shaft is fixedly connected to the center position of the winding wheel.

[0022] By adopting the above technical solution, the wire management ring is used to guide the towing rope, facilitating the smooth movement of the towing rope. The rotating shaft is used to support the winding wheel. When the winding wheel rotates, it winds up the towing rope, thereby causing the towing rope to move. When the towing rope moves, it exerts a pulling force on the pull rod through the through hole, thereby driving the square frame to move. The movement of the square frame drives the frame to move, and then the cable can be pulled to move, adjusting the pulling force on the cable.

[0023] Preferably, the limiting mechanism includes a ratchet wheel, a mounting block, a driving spring, a support shaft, and a stopper. The ratchet wheel is fixedly installed on the rotating shaft. The mounting block is fixedly installed inside the storage box. The driving spring is fixedly arranged on the mounting block. The support shaft is fixedly installed inside the storage box. The stopper is rotatably arranged on the support shaft, and one end of the stopper extends to one side of the ratchet wheel. The other end of the driving spring is fixedly connected to the stopper.

[0024] By adopting the above technical solution, turning the support shaft by the handle drives the ratchet wheel to rotate. When the ratchet wheel rotates, it pushes the stopper to move. The driving spring can exert pressure on the stopper, keeping the stopper always on one side of the ratchet wheel to prevent the winding wheel from rotating in the reverse direction. When the towing rope needs to be loosened, a pull rope is connected to the stopper, and one end of the pull rope extends out of the storage box. The pull rope can be pulled, thereby driving one end of the stopper to move and no longer limiting the ratchet wheel.

[0025] Preferably, a rotating ring is fixedly installed at the bottom end of the rotating shaft, and a handle is fixedly installed on the rotating ring.

[0026] By adopting the above technical solution, pushing the handle drives the rotating ring to rotate. When the rotating ring rotates, it drives the rotating shaft to rotate, and then the winding wheel can be driven to rotate through the rotating shaft, and then the towing rope can be wound up by the winding wheel.

[0027] The beneficial effects of the present invention are as follows:

[0028] 1. For the strain clamp with a stable clamping structure of the present invention, the through tube and the restraint belt are provided to facilitate improving the stability of limiting the cable. During the positioning and clamping of the cable, accidental sliding of the cable is avoided. One end of the fixed cable is passed through the through tube, and pushing the handle drives the rotating ring to rotate. When the rotating ring rotates, it drives the rotating shaft to rotate, and then the winding wheel can be driven to rotate through the rotating shaft, and then the towing rope can be wound up by the winding wheel. One end of the towing rope is fixedly connected to the through hole. When the towing rope is wound up, the pull rod slides inside the cylinder through the through hole. The movement of the pull rod drives the limiting block to move. The downward movement of the limiting block drives the restraint belt to move. The downward movement of the restraint belt contacts the top of the cable passing through the inside of the cylinder, thereby limiting the cable and clamping the cable, improving the stability of fixing the cable and avoiding accidental loosening of the cable, achieving the purpose of improving the clamping stability of the cable.

[0029] 2. The strain clamp with a stable clamping structure according to the present invention is provided with a traction rope and a winding wheel, which facilitate the adjustment of the cable tension, improve the flexibility of the strain clamp with a stable clamping structure. When adjusting the cable tension, continue to rotate the handle. The handle drives the support shaft to rotate, and the rotation of the support shaft drives the ratchet wheel to rotate. When the ratchet wheel rotates, it pushes the block to move. The driving spring can apply pressure to the block to keep the block always on one side of the ratchet wheel, preventing the winding wheel from rotating in the reverse direction. The rotating shaft is used to support the winding wheel. When the winding wheel rotates, it winds up the traction rope, and then the traction rope moves. When the traction rope moves, it applies a pulling force to the pull rod through the through hole, and then drives the square frame to move. The movement of the square frame drives the frame to move, and then the cable can be pulled to move, adjusting the cable tension, improving the flexibility of the strain clamp with a stable clamping structure, and the cable tightness can be adjusted according to the on-site needs.

[0030] 3. The strain clamp with a stable clamping structure according to the present invention is provided with a threaded section and a positioning nut, which facilitate the adjustment of the cable tightness.

[0043] Such as Figures 1 to 9As shown in the figure, a strain clamp with a stable clamping structure according to an embodiment of the present invention includes a frame 1. A conical groove 2 is provided inside the frame 1. A wire clamping assembly is provided inside the conical groove 2. A square frame 13 is fixedly installed at one end of the frame 1. A through cylinder 14 is provided inside the square frame 13. A positioning assembly is provided inside the square frame 13. A connection block 4 is fixedly installed on the frame 1. A hole 5 is provided inside the connection block 4. A support rod 9 passes through the hole 5. A support plate 21 is provided on the support rod 9. A traction assembly for pulling the square frame 13 is provided on the support plate 21. A guiding assembly is provided inside the conical groove 2. A limiting assembly is provided on the support rod 9. A pulling block 12 is fixedly installed on the support rod 9. When using the strain clamp with a stable clamping structure to fixedly clamp a cable, at the fixed location, the position of the support plate 21 is fixedly installed. Then, after one end of the fixed cable passes through the through cylinder 14 and the cable is arranged, the positioning assembly can be driven to move through the traction assembly. The positioning assembly can limit the cable passing through the inside of the through cylinder 14. Then, the cable is limited and clamped by the wire clamping assembly, thereby achieving the purpose of stable clamping of the cable and effectively avoiding the loosening of the cable. The pulling block 12 is connected by a steel wire rope, and the other end of the steel wire rope is fixedly connected to the fixed location, thereby positioning and installing one end of the cable. When adjusting the tension of the cable, through the movement of the traction assembly, the square frame 13 can be pulled to move. The movement of the square frame 13 can drive the cable to move and simultaneously drive the frame 1 to move synchronously, thereby adjusting the pulling force of the cable and improving the flexibility of the strain clamp with a stable clamping structure. The tightness of the cable can be adjusted according to the on-site needs. After moving the frame 1 to the predetermined position, the position of the frame 1 can be positioned through the limiting assembly.

[0044] As Figures 1 to 3 shown, the wire clamping assembly includes a conical block 6 and an arc groove 7. The conical block 6 is arranged inside the conical groove 2. The arc groove 7 is arranged on the conical block 6. When using the strain clamp with a stable clamping structure to fixedly clamp a cable, after one end of the cable is moved into the arc groove 7, then the conical block 6 is moved, so that the conical block 6 slides into the conical groove 2, thereby pressing on the outside of the conical block 6 and making the conical block 6 close inward, thereby fixedly clamping the cable. The conical block 6 is wedge-shaped. After the conical block 6 is placed inside the conical groove 2, when the conical block 6 moves towards the square frame 13, the conical groove 2 can press on the outer wall of the conical block 6.

[0045] As Figure 2 and Figure 3 shown, the guiding assembly includes a guiding groove 3 and a guiding block 8. The guiding groove 3 is arranged inside the frame 1 and the guiding groove 3 is communicated with the conical groove 2. The guiding block 8 passes through the guiding groove 3 and the guiding block 8 is fixedly connected to the conical block 6. When the conical block 6 moves, the cooperation of the guiding groove 3 and the guiding block 8 will guide the conical block 6 to move smoothly.

[0046] As Figure 1 and Figure 2 shown, the limit component includes a threaded section 10 and a positioning nut 11. The threaded section 10 is arranged on the support rod 9, and the threaded section 10 penetrates through the hole 5. The positioning nut 11 is threadedly connected to the threaded section 10. When the support rod 9 is fixedly connected to the frame 1, after one end of the threaded section 10 passes through the hole 5 and the positioning nut 11 is threadedly connected to the threaded section 10, rotating the positioning nut 11 will cause the positioning nut 11 to press on the connection block 4 after being threadedly connected to the threaded section 10, thereby enabling the connection of the frame 1.

[0047] As Figure 3 shown, the positioning component includes a load-bearing block 15, a cylinder 16, a limit block 17, a restraint belt 18, a pull rod 19, and a through hole 20. The load-bearing block 15 is fixedly installed inside the square frame 13. The cylinder 16 is inserted into the load-bearing block 15. The limit block 17 is arranged inside the square frame 13 and is located above the load-bearing block 15. The restraint belt 18 is fixedly installed on the limit block 17. The pull rod 19 is inserted into the cylinder 16, and one end of the pull rod 19 is fixedly connected to the limit block 17. The through hole 20 is arranged inside the pull rod 19. One end of the traction rope 29 is fixedly connected to the through hole 20. When the traction rope 29 is wound up, the pull rod 19 will be driven to slide inside the cylinder 16 through the through hole 20. The movement of the pull rod 19 will drive the movement of the limit block 17. The downward movement of the limit block 17 will drive the movement of the restraint belt 18. The downward movement of the restraint belt 18 contacts the top of the cable inserted into the cylinder 16, thereby enabling the limitation of the cable, and further enabling the clamping of the cable, improving the stability of the cable fixation and preventing the cable from loosening accidentally.

[0048] As Figure 5 、 Figure 6 and Figure 7 shown, a positioning block 35 is fixedly installed on the support plate 21. A positioning hole 36 is arranged inside the positioning block 35. A support cylinder 22 corresponding to the support rod 9 is arranged inside the support plate 21, and the support rod 9 penetrates through the support cylinder 22. When the fixed support frame at the installation location is connected to the positioning block 35 and a bolt is used in cooperation with the positioning hole 36, the support plate 21 can be fixedly installed.

[0049] As Figure 1 、 Figure 2 and Figure 4As shown in the figure, the traction assembly includes a storage box 23, a wire arranging ring 24, a winding mechanism and a limiting mechanism. The storage box 23 is fixedly installed at the bottom of the support plate 21. The wire arranging ring 24 is fixedly installed inside the storage box 23. The winding mechanism is arranged inside the storage box 23. The limiting mechanism is arranged inside the storage box 23. The wire arranging ring 24 guides and limits the traction rope 29. When the winding mechanism works, it can wind the traction rope 29. When the traction rope 29 moves, it will pull the square frame 13 to move. After moving the square frame 13 to a predetermined position, the winding mechanism can be positioned through the limiting mechanism, and then the square frame 13 can be positioned.

[0050] As Figure 7 and Figure 8 As shown in the figure, the winding mechanism includes a winding wheel 25, a rotating shaft 26 and a traction rope 29. The winding wheel 25 is arranged inside the storage box 23. The rotating shaft 26 is rotatably arranged inside the storage box 23, and one end of the rotating shaft 26 is fixedly connected to the center position of the winding wheel 25. One end of the traction rope 29 is fixedly wound around the winding wheel 25, and the other end of the traction rope 29 passes through the wire arranging ring 24 and is fixedly connected to the through hole 20. The wire arranging ring 24 is used to guide the traction rope 29 to facilitate the smooth movement of the traction rope 29. The rotating shaft 26 is used to support the winding wheel 25. When the winding wheel 25 rotates, it will wind the traction rope 29, and then the traction rope 29 will move. When the traction rope 29 moves, it will apply a pulling force to the pull rod 19 through the through hole 20, and then drive the square frame 13 to move. The movement of the square frame 13 will drive the frame 1 to move, and then the cable can be pulled to adjust the pulling force on the cable.

[0051] As Figure 9 As shown in the figure, the limiting mechanism includes a ratchet wheel 30, a mounting block 31, a driving spring 32, a support shaft 33 and a stop block 34. The ratchet wheel 30 is fixedly installed on the rotating shaft 26. The mounting block 31 is fixedly installed inside the storage box 23. The driving spring 32 is fixedly arranged on the mounting block 31. The support shaft 33 is fixedly installed inside the storage box 23. The stop block 34 is rotatably arranged on the support shaft 33, and one end of the stop block 34 extends to one side of the ratchet wheel 30. The other end of the driving spring 32 is fixedly connected to the stop block 34. By driving the support shaft 33 to rotate through the handle 28, the rotation of the support shaft 33 will drive the ratchet wheel 30 to rotate. When the ratchet wheel 30 rotates, it will push the stop block 34 to move. The driving spring 32 can apply pressure to the stop block 34 to make the stop block 34 always located on one side of the ratchet wheel 30 to prevent the winding wheel 25 from rotating in the reverse direction. When it is necessary to relax the traction rope 29, a pull rope is connected to the stop block 34, and one end of the pull rope extends out of the storage box 23. The pull rope can be pulled to drive one end of the stop block 34 to move and no longer limit the ratchet wheel 30.

[0052] As Figure 8As shown, a rotating ring 27 is fixedly installed at the bottom end of the rotating shaft 26, and a handle 28 is fixedly installed on the rotating ring 27. Pushing the handle 28 can drive the rotation of the rotating ring 27. When the rotating ring 27 rotates, it will drive the rotation of the rotating shaft 26. Furthermore, the winding wheel 25 can be driven to rotate through the rotating shaft 26, and then the towing rope 29 can be wound through the winding wheel 25.

[0053] Working principle: First, when using a strain clamp with a stable clamping structure to fixedly clamp a cable, a support frame is fixed at the installation location. After connecting to the positioning block 35, the support plate 21 can be fixedly installed by using bolts in cooperation with the positioning holes 36. Then, one end of the cable to be fixed is passed through the through cylinder 14, and the cable is arranged neatly. After one end of the cable is moved into the arc-shaped groove 7, the tapered block 6 is then moved, so that the tapered block 6 slides into the tapered groove 2, and then pressure can be applied to the outside of the tapered block 6, causing the tapered block 6 to close inward, and then the cable can be fixedly clamped. The tapered block 6 is wedge-shaped. Pushing the handle 28 can drive the rotation of the rotating ring 27. When the rotating ring 27 rotates, it will drive the rotation of the rotating shaft 26. Furthermore, the winding wheel 25 can be driven to rotate through the rotating shaft 26, and then the towing rope 29 can be wound through the winding wheel 25. One end of the towing rope 29 is fixedly connected to the through hole 20. When the towing rope 29 is wound, the pull rod 19 will be driven to slide inside the cylinder 16 through the through hole 20. The movement of the pull rod 19 will drive the movement of the limit block 17. The downward movement of the limit block 17 will drive the movement of the restraint belt 18. The downward movement of the restraint belt 18 contacts the top of the cable passing through the inside of the cylinder 16, and then the cable can be limited, and then the cable can be limited and clamped, improving the stability of the cable fixation and preventing the cable from loosening accidentally. When adjusting the tension of the cable, continue to rotate the handle 28. The support shaft 33 is driven to rotate by the handle 28. The rotation of the support shaft 33 will drive the rotation of the ratchet wheel 30. When the ratchet wheel 30 rotates, it will push the block 34 to move. The block 34 can be pressured by the driving spring 32, so that the block 34 is always located on one side of the ratchet wheel 30, preventing the winding wheel 25 from rotating in the reverse direction. The rotating shaft 26 is used to support the winding wheel 25. When the winding wheel 25 rotates, it will wind the towing rope 29, and then the towing rope 29 will move. When the towing rope 29 moves, a pulling force will be applied to the pull rod 19 through the through hole 20, and then the square frame 13 will be driven to move. The movement of the square frame 13 will drive the movement of the frame 1, and then the cable can be pulled to adjust the tension of the cable, improving the flexibility of the strain clamp with a stable clamping structure. The tightness of the cable can be adjusted according to the on-site needs. When the support rod 9 is fixedly connected to the frame 1, one end of the threaded section 10 is passed through the hole 5, and then the positioning nut 11 is threadedly connected to the threaded section 10. After rotating the positioning nut 11 and threadedly connecting the positioning nut 11 to the threaded section 10, pressure is applied to the connecting block 4, and then the frame 1 can be connected.
