Description

Technical Field

[0001] This invention relates to the field of power device technology, and in particular to a replaceable conductor tension string. Background Technology

[0002] Conductor tension strings are crucial load-bearing and insulating components in transmission lines. They typically consist of tension clamps, poles, insulator strings, and hanging rings, transferring conductor tension to the tower crossarms and ensuring electrical insulation between the conductor and the tower. During long-term operation, insulator strings require periodic maintenance and replacement due to factors such as wind and rain, dirt accumulation, and lightning flashover. Traditionally, replacing insulators on tension strings requires workers to carry specialized tensioning tools, first releasing the conductor from the tension clamps or temporarily anchoring it, before disassembling and installing the insulator string. This cumbersome and time-consuming process severely hinders maintenance efficiency.

[0003] Currently, in existing tension string structures, the two ends of the insulator string are typically connected to the rod and hanging ring using bolts or pins. While this connection method is simple and reliable, it requires specialized tools such as wrenches and sockets for disassembly and assembly when replacing insulator strings. The limited operating space, especially in high-altitude work environments, makes tool carrying inconvenient and bolt removal difficult. Furthermore, during replacement, the temporary transfer and fixation of conductor tension often relies on an external tensioner, which requires additional installation and adjustment. This not only increases the number of steps and labor intensity but also poses safety risks due to improper tensioning operations. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] In view of the aforementioned problem of inconvenient replacement of insulator strings, this invention is proposed.

[0006] Therefore, the object of this invention is to provide a conductor tension string that is easy to replace.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a replaceable conductor tension string, comprising a tension clamp, a hanging rod, an insulator string, and a hanging ring, and further comprising, Sleeve blocks are installed at both ends of the insulator string; The locking head is provided in two sets: one set is located on the side where the hanging rod connects to the insulator string, and the other set is located on the side where the hanging ring connects to the insulator string. Each locking head engages with the corresponding sleeve block to complete the assembly and disassembly of the insulator string. The locking head is equipped with a quick-release structure, which allows the assembly and disassembly of the insulator string to be done without the use of tools, making it convenient to replace the insulator string. The tensioning assembly is located on the outer wall of the tension clamp and on the side where the tension clamp is connected to the hanging rod pin. The assembly has a ratchet component inside, and the ratchet component has a pulling belt and a hook plate. The hook plate is pulled out from the tensioning assembly and connected to the crossarm on the utility pole. Then, the ratchet is rotated so that the hook plate and the pulling belt are stressed and hold the tension clamp, at which point the insulator string can be replaced.

[0008] As a preferred embodiment of the easily replaceable conductor tension string of the present invention, the hanging rod is connected to the tension clamp by a pin, and the hanging ring is movably connected to the crossarm of the pole, and the insulator string is connected by the hanging rod and the hanging ring.

[0010] As a preferred embodiment of the easily replaceable conductor tension string of the present invention, wherein: a movable rod is slidably connected inside the locking head, and one end of the movable rod extends to one side of the limiting post, and the other end of the movable rod is movably connected to the movable connecting rod. A connecting plate is installed at the extended end of the movable rod, and four sets of connecting plates are arrayed on the outer wall of the connecting plate. Four sets of protrusions are installed through the limiting post, and the end of the protrusion facing the inside of the limiting post is movably connected to the connecting plate.

[0011] As a preferred embodiment of the easily replaceable conductor tension string of the present invention, wherein: a rectangular rod is installed at the end of the screw, and the rectangular rod is embedded inside the rotating column.

[0012] As a preferred embodiment of the easily replaceable conductor tension string of the present invention, the tensioning assembly further includes a mounting cavity block installed on the tension clamp. The inner wall of the mounting cavity block is connected to a ratchet component. A limiting plate is installed on the inner wall of the mounting cavity block. A mounting spring is installed on one side of the limiting plate. The mounting spring applies pressure to the limiting plate, causing the limiting plate to engage with the ratchet of the ratchet component, so that the ratchet can only rotate in one direction.

[0013] As a preferred embodiment of the easily replaceable conductor tension string of the present invention, wherein: a pull block is embedded in the outer wall of the mounting cavity block, and the pull block is connected to the limiting plate for unlocking the ratchet component.

[0014] As a preferred embodiment of the easily replaceable conductor tension string of the present invention, the tensioning assembly further includes a hexagonal tightening post disposed at the rotating end of the ratchet component. The hexagonal tightening post facilitates the worker to rotate the ratchet component with a wrench. The ratchet component is connected to a restoring component.

[0015] As a preferred embodiment of the easily replaceable conductor tension string of the present invention, the restoring component includes a first gear installed on the rotating end of the ratchet component, the first gear being meshed with a second gear, the second gear being connected to the inside of the mounting cavity block via a mounting rod, the second gear being equipped with a torsion spring, and the other end of the torsion spring being connected to the inner wall of the mounting cavity block.

[0016] As a preferred embodiment of the easily replaceable conductor tension string of the present invention, the outer wall of the mounting cavity block is provided with a storage groove for embedding the hook plate, so that when the hook plate is not in use, the mounting cavity block is a complete cylindrical block and the interior of the mounting cavity block is a sealed area, making the internal components less prone to damage.

[0017] The technical solution provided by this invention has the following advantages compared with the known prior art: 1. By incorporating a locking head and sleeve block snap-fit ​​structure at both ends of the insulator string, along with a quick-release mechanism consisting of a rotating ring, screw, and protrusion, operators can control the extension and retraction of the protrusion simply by manually rotating the ring, achieving rapid locking and disengagement of the locking head and sleeve block. Compared to traditional bolt connections, insulator string assembly and disassembly can be completed without the need for wrenches or any external tools, significantly simplifying the operation process, reducing the amount of tools required for high-altitude operations, and shortening the overall replacement time for insulator strings, effectively improving line maintenance efficiency and operational convenience. Second, by integrating a tensioning assembly on one side of the tension clamp, and utilizing the cooperation of a ratchet, pulling belt, and hook plate, temporary transfer of conductor tension can be achieved simply by hooking the hook plate onto the crossarm and rotating the ratchet during operation, eliminating the need for carrying and installing an independent tensioner. The ratchet's one-way locking structure ensures stable and reliable tension; after replacement, pulling the pull block unlocks and resets the tension. The design is compact and safe to operate. This design eliminates the cumbersome installation and removal steps of the tensioner, reducing labor intensity and minimizing operational risks. Attached Figure Description

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0029] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0030] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0031] Reference Figure 1 , Figure 6 and Figure 5 This is one embodiment of the present invention, which provides an easily replaceable conductor tension string. Its core improvement lies in the structural design and ease of operation of the tensioning component 3.

[0032] Specifically, the tensioning assembly 3 includes a mounting cavity block 31 fixedly installed on the outer wall of the tension clamp 1. The mounting cavity block 31 is located on the side where the tension clamp 1 is connected to the pin of the hanging rod 11. It has a cylindrical structure with a hollow interior to form a receiving space. A ratchet 32 ​​is rotatably connected inside the mounting cavity block 31. The two ends of the rotating shaft of the ratchet 32 ​​are supported by bearings on the two side walls of the mounting cavity block 31, allowing it to rotate freely. A pulling belt 33 is wound on the winding surface of the ratchet 32. The protruding end of the pulling belt 33 passes through the strip opening in the side wall of the mounting cavity block 31 and is fixedly connected to the end with a hook plate 34. The hook plate 34 is used to hook onto the crossarm of the utility pole to form a fixed support point.

[0033] Furthermore, a limiting plate 35 is hinged to the inner wall of the mounting cavity block 31. The limiting plate 35 is located on one side of the ratchet component 32, and its free end is machined with locking teeth that match the ratchet tooth shape. A mounting spring 351 is provided on the side of the limiting plate 35 away from the ratchet component 32. One end of the mounting spring 351 abuts against the inner wall of the mounting cavity block 31, and the other end abuts against the plate surface of the limiting plate 35. The spring is always in a compressed state, continuously applying elastic pressure towards the ratchet component 32 to the limiting plate 35, so that the locking teeth of the limiting plate 35 naturally engage with the ratchet. The ratchet groove of component 32 enables the one-way locking function of the ratchet—that is, the ratchet component 32 can only rotate in the direction of the winding pull belt 33, and is locked by the limiting plate 35 in the opposite direction. A pull block 352 is also embedded in the outer wall of the mounting cavity block 31. The pull block 352 passes through the wall plate of the mounting cavity block 31 and is fixedly connected to the middle of the limiting plate 35. When the operator pulls the pull block 352 outward, it can overcome the elastic force of the mounting spring 351 and drive the limiting plate 35 to rotate around the hinge point, so that the locking teeth disengage from the ratchet component 32 and release the rotation restriction on the ratchet component 32.

[0034] Furthermore, a hexagonal tightening post 36 is coaxially fixedly connected to the rotating end of the ratchet component 32. The hexagonal tightening post 36 extends to the outside of the mounting cavity block 31, making it convenient for workers to use tools such as wrenches to engage it and actively rotate the ratchet component 32. A restoring component 37 is also connected to the rotating shaft of the ratchet component 32. The restoring component 37 includes a first gear 371 fixedly installed on the rotating end of the ratchet component 32. The first gear 371 is meshed with a second gear 372. The second gear 372 is rotatably connected to the inside of the mounting cavity block 31 through the mounting rod 373. A torsion spring 374 is fixedly installed on the end face of the second gear 372. The other end of the torsion spring 374 is fixedly connected to the inner wall of the mounting cavity block 31. When the ratchet 32 ​​rotates in the winding direction, the first gear 371 drives the second gear 372 to rotate. The rotation of the second gear 372 causes the torsion spring 374 to undergo torsional deformation and store elastic potential energy. When the limit plate 35 is unlocked, the torsion spring 374 releases its elastic potential energy, drives the second gear 372 to reverse, and then drives the ratchet 32 ​​to reverse through the first gear 371, so that the pull belt 33 automatically retracts into the mounting cavity block 31.

[0035] Furthermore, the outer wall of the mounting cavity block 31 is provided with a storage groove 38. The outline of the storage groove 38 is adapted to the hook plate 34 and is used to embed and accommodate the hook plate 34. When not in use, the hook plate 34 is completely sunk into the storage groove 38, keeping the outer wall of the mounting cavity block 31 as a complete cylindrical surface. This avoids the hook plate 34 being exposed and causing scratches or snagging risks. At the same time, the interior of the mounting cavity block 31 is a sealed area, which can effectively prevent external impurities such as dust and rainwater from entering, protecting internal precision components such as the ratchet 32, gear transmission mechanism, and torsion spring 374, and extending their service life. The hanging rod 11 is connected to the tension clamp 1 by a pin, and the hanging ring 13 is movably connected to the crossarm of the pole. The insulator string 12 is connected through the hanging rod 11 and the hanging ring 13.

[0036] Operation process: When replacing the insulator string 12, the operator only needs to carry the new insulator string 12 and a wrench. At this time, the operator pulls the locking block, which releases the restriction of the limiting plate 35 on the ratchet component 32. Then, the hook plate 34 can be separated from the outer wall of the mounting cavity block 31, so that the hook plate 34 is connected to the crossarm of the pole. When the hook plate 34 pulls the pulling belt 33, the pulling belt 33 drives the ratchet component 32 to rotate. When the ratchet component 32 rotates, it drives the first gear 371 and the second gear 372 to rotate, which causes the torsion spring 374 to rotate at this time. After the hook plate 34 is connected to the crossarm, the pull block 352 is released. At this time, the worker can use a wrench to tighten the hexagonal tightening post 36. The rotation of the hexagonal tightening post 36 drives the ratchet 32 ​​to rotate. The rotation of the ratchet 32 ​​gradually winds up the pulling belt 33. The winding of the pulling belt 33 causes the pulling belt 33 and the hook plate 34 to apply tension force to the tension clamp 1. At this time, the insulator string 12 can be disassembled. This structure eliminates the need for workers to carry their own tensioner and saves the troublesome process of connecting the tensioner to the conductor, effectively improving the replacement efficiency of the insulator string 12.

[0037] Example 2 Reference Figure 1 - Figure 5 This is the second embodiment of the present invention, which differs from the first embodiment in that the locking head 2 has a quick-release structure design.

[0038] Specifically, the locking head 2 has a cylindrical structure. An annular limiting post 21 is fixedly installed on the outer peripheral wall of its end facing the sleeve 121. The outer diameter of the limiting post 21 matches the inner diameter of the sleeve 121, allowing it to be inserted into the sleeve 121 for initial positioning. A rotating ring 22 is rotatably mounted on the outer wall of the locking head 2 via a bearing. The outer peripheral surface of the rotating ring 22 is machined with anti-slip knurling for easy hand-grip rotation. A rotating column 23 is rotatably mounted in the inner cavity of the locking head 2 via a bearing. One end of the rotating column 23 is fixedly connected to the inner ring of the rotating ring 22, allowing the rotation of the rotating ring 22 to be directly transmitted to the rotating column 23. An axially extending rectangular sliding hole is provided inside the rotating column 23. A rectangular rod 241 is slidably fitted within this rectangular sliding hole. One end of the rectangular rod 241 extends out of the rotating column 23 and is fixedly connected to a screw 24. The sliding fit between the rectangular rod 241 and the rectangular sliding hole allows the screw 24 to rotate synchronously with the rotating column 23 while also sliding freely axially.

[0039] Furthermore, the outer wall of the screw 24 is machined with external threads, and the inner wall of the locking head 2 is correspondingly provided with internal threads, and the screw 24 is threadedly engaged with the internal threads. Furthermore, the end of the screw 24 away from the rectangular rod 241 is movably hinged to the movable connecting rod 25 via a pin. The locking head 2 is also slidably provided with a moving rod 26 along the axial direction. One end of the moving rod 26 extends to the side where the limiting post 21 is located and passes through the central area of ​​the limiting post 21. The other end of the moving rod 26 is movably connected to the end of the movable connecting rod 25 via a pin. The extended end of the moving rod 26 is fixedly installed with a connecting plate 27. Four sets of connecting plates 28 are evenly arrayed along the circumference of the outer wall of the connecting plate 27. Four sets of guide holes penetrating the wall thickness are correspondingly opened on the circumferential wall of the limiting post 21. A set of protrusions 29 are slidably installed in each guide hole. The end of the protrusion 29 facing the inside of the limiting post 21 is provided with a hinge seat, which is movably connected to the outer end of the corresponding connecting plate 28 through the hinge seat. Furthermore, when the moving rod 26 moves axially, the four sets of protrusions 29 can be simultaneously extended and retracted along the radial direction of the limiting post 21 through the linkage of the connecting plate 27 and the connecting plate 28. When the moving rod 26 moves towards the limiting post 21, the connecting plate 28 pushes the protrusions 29 outward, so that the outer end of the protrusions 29 protrudes out of the outer wall surface of the limiting post 21. When the moving rod 26 retracts, the connecting plate 28 pulls the protrusions 29 inward, so that the outer end of the protrusions 29 retracts to a position flush with or lower than the outer wall surface of the limiting post 21.

[0040] Furthermore, four sets of slots are provided on the inner wall of the sleeve 121 to match the position of the protrusion 29. When the limiting post 21 is inserted into the sleeve 121 and the protrusion 29 protrudes outward, the protrusion 29 is embedded in the slot, forming an axial lock, so that the locking head 2 cannot be dislodged from the sleeve 121. When the protrusion 29 is retracted, the locking head 2 can be freely pulled out from the sleeve 121.

[0041] The rest of the structure is the same as in Example 1.

[0042] Operation process: After connecting the tension clamp 1 to the crossarm, the rotating ring 22 can be rotated. The rotation of the rotating ring 22 drives the rotating column 23 to rotate, which in turn drives the screw 24 to rotate. The sliding connection between the screw 24 and the rotating column 23 causes the screw 24 to rotate and move. The movement of the screw 24 drives the movable connecting rod 25 to move, which in turn drives the moving rod 26 to move. The movement of the moving rod 26 drives the connecting plate 28 to move, which in turn drives the protrusion 29 to move. At this time, the protrusion 29 retracts into the limiting post 21, so that the limiting post 21 is no longer locked in the sleeve block 121. On the outside, the locking head 2 can be directly removed from the sleeve block 121. Both ends of the insulator string 12 are disassembled in the same way. During subsequent installation, the sleeve block 121 of the new insulator string 12 is snapped onto the locking head 2. At this time, the rotating ring 22 is reversed, and its protrusion 29 protrudes again from the outer wall of the limiting post 21. The limiting post 21 is embedded in the sleeve block 121 and protrudes from the outer wall of the sleeve block 121, so that the protruding protrusion 29 can lock and restrict the locking head 2 inside the sleeve block 121, thereby completing the rapid replacement of the insulator string 12 and improving the replacement efficiency of the conductor tension string.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
