Technical Field
[0001] The present application relates to the technical field of cable installation equipment, and in particular to a cable installation device for an electric power tower. Background Art
[0002] At present, with the development of power systems, power cables have been widely used in modern power systems. In the construction of power transmission and distribution lines, iron towers are commonly used poles, and the power cables laid on them are one of the common ways to transform and construct power transmission and distribution lines. Power towers not only support and protect overhead wires, but also play an important role in the construction of power systems. Cables are suspended on iron towers through insulator strings to improve safety when powered on. Since most power towers are installed in outdoor environments, insulators are easily damaged by long-term exposure to the natural environment, so workers are required to regularly maintain and replace insulator strings. In the related art, an insulator string includes a number of insulators and a connecting block spaced apart from the insulators. When replacing an insulator string, the operator needs to pull and position the cable through an additional pulling device, so that the insulator string to be replaced is in a relaxed state, thereby facilitating the disassembly of the old insulator string, and then install the new insulator string to the original position, release the pulling device, so that the new insulator string is in a tensioned state, and then complete the replacement of the insulator string.
[0003] Regarding the above-mentioned related technologies: when replacing the insulator string, the operator needs to carry additional pulling equipment, and during the high-altitude operation, the operating space is limited, which makes the transportation and assembly of the pulling equipment complicated, increases the work intensity of the operator, and thus there is a problem of inconvenience in replacing the insulator. Summary of the invention
[0004] In order to facilitate the replacement of insulators, the present application provides a cable installation device for a power tower.
[0005] The present application provides a cable installation device for a power tower, which adopts the following technical solution:
[0006] A cable installation device for an electric power tower comprises a hanging member connected to the electric power tower and a positioning member connected to the cable, at least one set of insulator strings are connected between the hanging member and the positioning member, and further comprises:
[0007] A support frame, wherein the support frame is connected to the positioning member and the suspension member respectively;
[0008] A pulling mechanism is slidably arranged on the support frame, and the pulling mechanism can be connected to the insulator string to adjust the tightness of the insulator string;
[0009] The lifting mechanism is arranged between the pulling mechanism and the power iron tower, and is used to connect with a single insulator in the insulator string and drive the insulator to rise and fall.
[0010] By adopting the above technical solution, the support frame connects the suspension member and the positioning member together to form a stable structural foundation, so that the support frame can be used to support the pulling mechanism, and the pulling mechanism can slide on the support frame, so as to flexibly adjust the position of the pulling mechanism, so as to facilitate the connection of the pulling mechanism with the insulators at different positions in the insulator string, so that when the insulator needs to be replaced, the operator can adjust the tightness of the insulator string at the insulator to be replaced through the pulling mechanism, so that the insulator string is in a relaxed state, so as to facilitate the removal of the old insulator, and at the same time, the lifting mechanism can be connected to the insulator and drive the insulator to rise and fall, so as to facilitate the lowering of the old insulator to the ground and the bringing of the new insulator to the position of the insulator string, so as to facilitate the replacement of the insulator, and further simplify the replacement process. Moreover, this design not only reduces the tools and equipment that the operator needs to carry, but also improves the work efficiency and reduces the risk of high-altitude operations.
[0011] Optionally, the pulling mechanism includes two pulling rings and adjustment components respectively connected to the two pulling rings, the two pulling rings are respectively slidably arranged on the support frame and are parallel to each other, the two pulling rings are respectively provided with clamping components, the clamping components are used to clamp the insulator string, and the adjustment components are used to adjust the distance between the two pulling rings.
[0012] By adopting the above technical solution, the two pulling rings can move freely on the support frame, so as to facilitate moving the two pulling rings to the two sides of the insulator to be replaced, and each pulling ring is provided with a clamping assembly, which can firmly clamp the insulator string to ensure that no slippage occurs when adjusting the tightness of the insulator string. Therefore, when the two pulling rings are located at the specified position and the clamping assembly clamps the insulator string, the operator can adjust the distance between the two pulling rings by adjusting the assembly to accurately control the tightness of the insulator string, thereby facilitating the operator to easily adjust the state of the insulator string when working at high altitude, reducing the need to carry additional pulling equipment, reducing work intensity, and improving work efficiency.
[0013] Optionally, the clamping assembly includes a driving member and a clamping jaw, wherein two clamping jaws are provided, the two clamping jaws are symmetrically arranged and are respectively slidably connected to the pulling ring, the number of the driving members is equal to the number of the clamping jaws and are arranged one-to-one, the driving member is arranged on the pulling ring, and the driving member is used to drive the clamping jaws to move closer to or away from the insulator.
[0014] By adopting the above technical solution, the driving member can accurately control the clamping jaws to approach or move away from the insulator, so that the two clamping jaws cooperate with each other and can firmly clamp the insulator string to avoid slipping when adjusting the tightness of the insulator string.
[0015] Optionally, a receiving groove and a through groove are respectively provided on the pulling ring, the through groove is connected to the receiving groove, one end of the clamping jaw is slidably arranged in the through groove, the driving member includes a handle, a gear and a rack, the rack is arranged on the clamping jaw, the gear is inserted in the receiving groove and is rotatably connected to the pulling ring, the gear and the rack are meshed with each other, the handle is coaxial with the gear and is fixedly connected, and one end of the handle extends to the surface of the pulling ring.
[0016] By adopting the above technical solution, when the tightness of the insulator string needs to be adjusted, the operator can rotate the handle to drive the gear to rotate, and the gear and the rack are meshed with each other, so that the clamp moves along the through slot, so that the clamp clamps the insulator string or separates the clamp from the insulator string, thereby facilitating the adjustment of the position of the clamp. And because all components are integrated on the pulling ring, there is no need to carry other tools, which further reduces the workload of the operator.
[0017] Optionally, a sliding groove is provided on the pulling ring, and the sliding groove is connected to the receiving groove. The clamping assembly includes a clamping piece, and the clamping piece is slidably arranged in the sliding groove. One end of the clamping piece extends out of the sliding groove. An elastic piece is arranged between the clamping piece and the inner wall of the sliding groove, and the elastic piece is used to drive one end of the clamping piece to be inserted into the receiving groove and interfere with the gear.
[0018] By adopting the above technical solution, when the position of the clamping jaw needs to be adjusted, the clamping piece is pulled to disengage the clamping piece from the gear, and at the same time, the clamping piece applies pressure to the elastic piece to compress the elastic piece, and then the handle is turned, and the handle drives the rack to move through the gear, so as to adjust the position of the clamping jaw. And when the clamping jaw moves to the specified position, the clamping piece is released, so that the elastic piece drives the clamping piece to move into the receiving groove, so that the clamping piece and the gear collide. At this time, the gear is not easy to rotate, so it is convenient to limit the clamping jaw by the gear and the rack, so that the clamping jaw is not easy to move, which is conducive to improving the reliability and stability of the clamping jaw during use.

[0020] By adopting the above technical solution, the threads on the first threaded rod and the second threaded rod rotate in opposite directions, so that when the connecting rod is rotated, the first threaded rod and the second threaded rod rotate synchronously to drive the two pulling rings to move closer or farther synchronously. This design can achieve precise adjustment of the distance between the two pulling rings, ensuring that the insulator string remains balanced and stable when adjusting the tightness, avoiding deflection or damage caused by unilateral force. In addition, quick adjustment can be achieved through simple rotation operation, which improves the convenience and efficiency of operation and reduces the workload of operators.
[0021] Optionally, the lifting mechanism includes a winding assembly, a transfer assembly and a rope fixing assembly, the winding assembly is arranged on the power tower, the transfer assembly is arranged on the adjustment assembly and is located between the two pulling rings, one end of the rope fixing assembly is arranged on the winding assembly, and the other end of the rope fixing assembly is slidably connected to the transfer assembly, and the end of the rope fixing assembly close to the transfer assembly can pass through the transfer assembly to connect with the insulator.
[0022] By adopting the above technical solution, when a single insulator needs to be raised or lowered, the rope fixing assembly is first connected to the insulator, and then the winding assembly is used to control the retraction and extension of the rope fixing assembly, thereby achieving accurate lifting and lowering of the insulator. In addition, the transfer group can effectively reduce the friction of the rope fixing assembly, ensuring the smoothness and stability of the rope fixing assembly during movement.
[0023] Optionally, the winding assembly includes a winding roller and a winding drive, the winding drive is arranged on the power iron tower, the winding roller is rotatably connected to the power iron tower and connected to the winding drive, and the winding drive is used to drive the winding roller to rotate;
[0024] The rope fixing assembly includes a pulling rope, one end of which is wound around the winding roller, and the other end of which passes through the transfer assembly and is respectively connected to two positioning ropes. The two positioning ropes are respectively provided with hooks at one end away from the pulling rope, and the positioning ropes can be wound around the insulator and fixed by the hooks.
[0025] By adopting the above technical solution, when a single insulator needs to be raised or lowered, the positioning rope is first wound around the insulator and fixed by a hook, and then the winding roller is driven to rotate by the winding drive, so that the pulling rope wound around the winding roller is tightened or loosened, thereby facilitating the use of the pulling rope to drive the insulator to be raised or lowered. In this process, the two positioning ropes can be fixed at both ends of the insulator, which can effectively disperse the force points on the one hand to avoid the risk of insulator damage caused by excessive force on a single point, further improving the safety and efficiency of the insulator replacement process; on the other hand, it enables the insulator to maintain a stable posture in the air, which reduces the shaking of the insulator during the lifting process to a certain extent, further improving the efficiency and reliability of the replacement operation.

[0027] By adopting the above technical solution, the design of the intermediate base and the intermediate wheel enables the pulling rope to slide smoothly on the intermediate wheel, reducing the energy loss caused by friction and ensuring the uniform transmission of force. When the insulator does not need to be replaced, the hook can be connected to the protrusion to fix the position of the hook, which is conducive to reducing the possibility of collision between the hook and the insulator, resulting in damage to the insulator, and thus helping to enhance the stability and safety of the system.

[0029] By adopting the above technical solution, the meshing structure of the worm wheel and the worm has a large transmission ratio, which can achieve a small input force to produce a large output torque, so that the winding roller can rotate smoothly and ensure the uniform retraction and release of the pulling rope. At the same time, the self-locking characteristics of the worm wheel and the worm can keep the winding roller in the current position in unexpected situations, prevent the pulling rope from loosening, and improve the safety and reliability of the system.

[0049] Reference Figure 2 and Figure 3 The two pulling rings 41 are respectively provided with a clamping assembly 43, and the clamping assembly 43 includes a driving member 431, a clamping claw 432 and a clamping member 433 (refer to Figure 4 ). There are two clamping jaws 432 on the same pulling ring 41, and the two clamping jaws 432 are symmetrically arranged. A through slot 411 is provided on the pulling ring 41, and the number of the through slots 411 is equal to the number of the clamping jaws 432. One clamping jaw 432 is slidably inserted in one through slot 411, and a limiting block 4321 is provided on one side of the clamping jaw 432 close to the circumferential outer wall of the pulling ring 41. The size of the limiting block 4321 is larger than the size of the through slot 411, so that the clamping jaw 432 can be easily limited to the pulling ring 41 by using the limiting block 4321.
[0050] The number of the driving members 431 is equal to the number of the clamping jaws 432 and is arranged one by one, and the driving member 431 includes a handle 4311, a gear 4312 and a rack 4313. The rack 4313 is fixedly connected to the clamping jaw 432 and arranged along the length direction of the clamping jaw 432.
[0051] The pulling ring 41 is provided with a receiving groove 412, and the receiving groove 412 is connected to the through groove 411. The gear 4312 is inserted into the receiving groove 412 and is rotatably connected to the pulling ring 41, and the gear 4312 is meshed with the rack 4313.

[0052] Reference Figure 3 and Figure 4 A slide groove 413 is provided on the pulling ring 41, and the slide groove 413 is connected to the receiving groove 412. The clamping member 433 is slidably arranged in the slide groove 413, one end of the clamping member 433 extends out of the slide groove 413, and an elastic member 414 is arranged between the clamping member 433 and the inner wall of the slide groove 413. In this embodiment, the elastic member 414 is a spring, so that the elastic member 414 is used to drive the clamping member 433 to be inserted into the receiving groove 412 and to contact the gear 4312, and then the clamping member 433 is used to lock the gear 4312 to prevent the clamping jaw 432 from being accidentally released.
[0053] Reference Figure 3 and Figure 4 When the insulator needs to be clamped, first move the pulling ring 41 to the specified position, then pull the clamping member 433 to disengage the clamping member 433 from the gear 4312, and at the same time, make the clamping member 433 apply pressure to the elastic member 414 to compress the elastic member 414. Next, turn the handle 4311, the handle 4311 drives the gear 4312 to rotate, and the gear 4312 drives the rack 4313 to move, so that the rack 4313 drives the clamping claw 432 to move, so that the clamping claw 432 is pressed against the insulator. At this time, release the clamping member 433, so that the elastic member 414 drives the clamping member 433 to move into the accommodating groove 412, so that the clamping member 433 and the gear 4312 are in conflict, so that the two clamping claws 432 can firmly clamp the insulator.
[0054] Reference Figure 2 The adjustment assembly 42 includes a first threaded rod 421, a connecting rod 422, and a second threaded rod 423 that are connected in sequence. The first threaded rod 421 is threadedly connected to one pulling ring 41, and the second threaded rod 423 is threadedly connected to another pulling ring 41, and the threads on the first threaded rod 421 and the second threaded rod 423 are in opposite directions. In this way, by rotating the first threaded rod 421 and the second threaded rod 423, the two pulling rings 41 can be synchronously moved closer or farther away to adjust the distance between the two pulling rings 41.
[0055] In this embodiment, a force-applying portion 4211 is fixedly connected to one end of the first threaded rod 421 away from the connecting rod 422, so that an operator can use a tool or directly manually rotate the first threaded rod 421, and drive the second threaded rod 423 to rotate through the connecting rod 422. In other embodiments, the force-applying portion 4211 may not be provided, and the first threaded rod 421 and the second threaded rod 423 may be driven to rotate directly through the connecting rod 422.
[0056] Reference Figure 1 and Figure 2 The lifting mechanism 5 includes a winding assembly 51, a transfer assembly 52 and a rope fixing assembly 53. The winding assembly 51 is mounted on the power tower 6, the transfer assembly 52 is mounted on the connecting rod 422, one end of the rope fixing assembly 53 is arranged on the winding assembly 51, the other end of the rope fixing assembly 53 is slidably connected to the transfer assembly 52, and the end of the rope fixing assembly 53 close to the transfer assembly 52 can pass through the transfer assembly 52 to connect with the insulator.
[0057] Reference Figure 1 and Figure 5The winding assembly 51 includes a winding roller 511 and a winding driving member 512. The winding roller 511 is rotatably connected to the power tower 6, and the winding driving member 512 includes a worm wheel 5121 and a worm 5122. The worm wheel 5121 and the worm 5122 are rotatably connected to the power tower 6, respectively. The worm wheel 5121 and the worm 5122 are meshed with each other, and the worm wheel 5121 is coaxial with the winding roller 511 and fixedly connected, so that the worm 5122 can be used to drive the worm wheel 5121 to rotate, so as to drive the winding roller 511 to rotate.
[0058] In this embodiment, the worm wheel 5121 and the worm 5122 are respectively located inside the power tower 6, and one end of the worm 5122 away from the worm wheel 5121 is fixedly connected to a turntable, so that the operator can drive the worm 5122 to rotate through the turntable.
[0059] Reference Figure 2 and Figure 6 The transfer assembly 52 includes a transfer seat 521 and a transfer wheel 522 rotatably connected to the transfer seat 521. The transfer seat 521 is rotatably connected to the connecting rod 422, so that the transfer seat 521 and the connecting rod 422 can rotate relative to each other, thereby reducing the possibility of driving the transfer seat 521 to rotate when the connecting rod 422 rotates.
[0060] In other embodiments, a limiting rod may also be connected to the intermediate transfer seat 521 , and the limiting rod is connected to the support rod 31 , so that the intermediate transfer seat 521 is not easily rotated along with the rotation of the connecting rod 422 .
[0061] Reference Figure 5 and Figure 7 The rope fixing assembly 53 includes a pulling rope 531, one end of which is wound around the winding roller 511, and the other end of which is connected to the rotating wheel 522 (refer to Figure 6 ) is slidably connected, and one end of the pulling rope 531 passes through the rotating wheel 522 and is fixedly connected to two positioning ropes 532 respectively, and one end of the two positioning ropes 532 away from the pulling rope 531 is fixedly connected to a hook 533 respectively, and the positioning rope 532 can be wrapped around the insulator and fixed by the hook 533.
[0062] When a single insulator needs to be raised or lowered, the positioning rope 532 is first wound around the insulator and fixed by the hook 533, and then the worm 5122 is rotated. The worm 5122 drives the winding roller 511 to rotate through the worm wheel 5121, so that the pulling rope 531 wound around the winding roller 511 is tightened or loosened, and the pulling rope 531 drives the positioning rope 532 to move, thereby facilitating the use of the pulling rope 531 to drive the insulator to be raised or lowered.
[0063] During the lifting and lowering process of the insulator, since the two positioning ropes 532 can be fixed at the two ends of the insulator respectively, on the one hand, the force points can be effectively dispersed to avoid the risk of insulator damage due to excessive force at a single point, thereby further improving the safety and efficiency of the insulator replacement process; on the other hand, it enables the insulator to maintain a stable posture in the air, which to a certain extent reduces the shaking of the insulator during the lifting process, further improving the efficiency and reliability of the replacement operation.
[0064] Reference Figure 7 In this embodiment, a protrusion 5211 is integrally formed on the top of the transfer seat 521, so that when the insulator does not need to be replaced, the hook 533 can be connected to the protrusion 5211 to fix the position of the hook 533, which is beneficial to reduce the possibility of collision between the hook 533 and the insulator, causing damage to the insulator, and to enhance the stability and safety of the system to a certain extent.
[0065] The implementation principle of a cable installation device for an electric power tower in an embodiment of the present application is as follows: when the insulator needs to be replaced, first move the pulling ring 41 to the insulator to be replaced, then pull the clamping piece 433, and drive the gear 4312 to rotate through the handle 4311, and the gear 4312 drives the clamping jaw 432 to move through the rack 4313, so that the two clamping jaws 432 clamp the insulator.
[0066] Next, the first threaded rod 421 is rotated by the force applying part 4211, and the connecting rod 422 and the second threaded rod 423 are rotated synchronously, so as to drive the two pulling rings 41 to move synchronously, so that the insulator string 7 is in a relaxed state. Then, the positioning rope 532 is wound around the old insulator and fixed by the hook 533, and the old insulator is removed. Then, the worm 5122 is rotated, and the worm 5122 drives the winding roller 511 to rotate through the worm gear 5121 to unwind the pulling rope 531, so as to slowly lower the old insulator to the ground.
[0067] Finally, the new insulator is connected using the positioning rope 532 and the hook 533, and the worm 5122 is rotated in the opposite direction to reel in the pulling rope 531, thereby bringing the new insulator to the position of the insulator string 7, so that the operator can install the new insulator on the insulator string 7, thereby completing the insulator replacement operation.
[0068] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
