Description

Technical Field

[0001] The invention relates to a spare wire clamp for an overhead power transmission line, a wire clamp installation device and an installation method, and belongs to the technical field of cable installation. Background Art

[0002] In the field of power transmission, overhead power lines are a widely used facility. They consist of line towers, overhead wires, insulators, hardware, guy wires, tower foundations, grounding devices and other parts. They are erected above the ground and are mainly used to transmit electrical energy between two points in the system.

[0003] Overhead transmission lines are prone to metal fatigue during use due to the influence of the external environment and their own stress, which can lead to strand breakage. To prevent long-term power outages, backup wire clamps need to be installed on the transmission lines to ensure smooth circuit operation. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a spare wire clamp for an overhead power transmission line, a wire clamp installation device and an installation method, which solves the problem in the prior art that the transmission line will be out of power for a long time after a strand break accident occurs in the overhead power transmission line.

[0005] The technical problem to be solved by the present invention is achieved by adopting the following technical solution: a spare wire clamp for an overhead transmission line, comprising a transmission line and an inner lining stranded wire bundle hinged around the surface of the transmission line, wherein the inner lining stranded wire bundle is provided with an outer separation layer, and further comprising:

[0006] The wire clamp mounting block is set on the radial side of the transmission line.

[0007] The connecting plate and the wire clamp mounting block can be detachably fixed.

[0008] The fixing block is fixed on the side of the connecting plate close to the transmission line.

[0009] The power line fixing clamp is arranged on the side of the power line away from the clamp mounting block. The power line fixing clamp is clamped around the outside of the outer separation layer and the end thereof is detachably fixedly connected to the fixing block.

[0010] The wire clamp fixing sleeve is set in the wire clamp mounting block. Two wire clamp fixing sleeves are set side by side. The wire clamp fixing sleeves can only be slid along the extension direction of the transmission line.

[0011] One end of the tension stranded wire bundle is hinged around the lining stranded wire bundle, and the other end of the tension stranded wire bundle is fixed on a tube with a connector.

[0012] The connecting bolt is fixed on the end of the connector away from the tension stranded wire bundle, and the connecting bolt is threadedly connected to the wire clamp fixing sleeve.

[0013] Among them, the connecting plate is arranged on the opposite side of the wire clamp mounting block in the extension direction of the transmission line. The wire clamp mounting block is also fixed with an external clamp for fixing the wire clamp mounting block. There are two tension stranded wire bundles and they are respectively arranged on the opposite sides of the wire clamp mounting block in the extension direction of the transmission line.

[0014] By adopting the above technical solution, the wire clamp mounting block is fixed to the external support structure through an external clamp, and then the transmission line is fixed to the wire clamp mounting block through the transmission line fixing clamp. At this time, one end of the tension stranded wire bundle is hinged on the lining stranded wire bundle, and the other end of the tension stranded wire bundle is fixed to the wire clamp mounting block by connecting bolts and the wire clamp fixing sleeve. At this time, the tension stranded wire bundle can provide auxiliary support for the lining stranded wire bundle. At the same time, when the transmission line is broken due to broken strands or metal fatigue, the tension stranded wire bundle can continue to tighten the transmission line and connect to the transmission line, and conduct the current of the transmission line through the wire clamp mounting block to another tension stranded wire bundle, and then transmit it to the other broken section of the transmission line. At this time, the current can be conducted through the spare wire clamp. The tension stranded wire bundle not only shares the tension of the transmission line, but also can temporarily conduct current, reducing the loss caused by the transmission line break accident.

[0015] A wire clamp installation device for a spare wire clamp of an overhead power transmission line, used for installing the spare wire clamp, comprising:

[0016] The auxiliary fixing clamp is set on the side of the power transmission line away from the wire clamp mounting block. The auxiliary fixing clamp is set in a U shape and the power transmission line passes through the middle of the auxiliary fixing clamp. The two ends of the auxiliary fixing clamp are provided with connection structures connected to the wire clamp mounting block.

[0017] The auxiliary mounting block is detachably fixed on the wire clamp mounting block. The auxiliary mounting block is provided with an insertion slot and a locking slot respectively connected to the wire clamp fixing sleeve.

[0018] Among them, the inner side surface of the auxiliary mounting block is fitted with the outer side surface of the wire clamp mounting block, the insertion slot and the locking slot are respectively located on opposite sides of the wire clamp mounting block, and the auxiliary mounting block is provided with an adjustment structure for pulling the connecting bolt toward the wire clamp mounting block after the wire clamp fixing sleeve is threadedly connected to the connecting bolt.

[0019] By adopting the above technical solution, the auxiliary fixing clamp is first used to temporarily connect the transmission line to be connected to the wire clamp mounting block with the transmission line and keep it stable, and then the connecting plate is installed on the wire clamp mounting block. Finally, after the inner lining stranded wire bundle and the outer partition layer are installed in sequence, the transmission line fixing clamp is clamped on the outer partition layer, and the transmission line fixing clamp is fixedly connected to the fixing block to complete the fixation of the transmission line. This can ensure that the transmission line is in a tensioned state as a whole when the wire clamp is installed. At the same time, the auxiliary fixing clamp can temporarily support the transmission line, making the transmission line less likely to shake, thereby improving the installation convenience of the spare wire clamp.

[0020] The present invention is further configured as follows: the connection structure includes:

[0021] Extrusion grooves are opened at both ends of the U-shaped auxiliary fixing clamp.

[0022] One end of the elastic strip is fixed to the inner wall of the extrusion groove, and the other end of the elastic strip is bent in the direction away from the auxiliary fixing clamp.

[0023] Auxiliary fixing cavity, opened inside the wire clamp mounting block,

[0024] Among them, the auxiliary fixing clip is U-shaped, and both ends extend into the auxiliary fixing cavity and the bent end of the elastic strip abuts against the inner wall of the auxiliary fixing cavity. The auxiliary fixing clip is provided with a disassembly part that retracts the bent end of the elastic strip toward the extrusion groove and releases the elastic strip from abutting against the inner wall of the auxiliary fixing cavity.

[0025] The present invention is further configured as follows: the disassembly portion includes:

[0026] The disassembly slot is opened on the side of the auxiliary fixing clip away from the wire clamp mounting block.

[0027] The threading channel is opened in the auxiliary fixing clamp, one end of the threading channel is connected to the extrusion groove, and the other end of the threading channel is connected to the disassembly groove.

[0028] The disassembly rope has an extension path in the threading channel. One end of the disassembly rope extends into the extrusion groove and is fixed to the bent end of the elastic strip. The other end of the disassembly rope extends into the disassembly groove.

[0029] The disassembly thread block has threads arranged in the disassembly groove, and the disassembly thread block is fixed to the end of the disassembly rope.

[0030] When the clamp is fully inserted into the auxiliary fixing cavity, the elastic strip is reset and expanded under the elastic action and abuts against the inner wall of the auxiliary fixing cavity. At this time, the auxiliary fixing clip cannot fall out of the auxiliary fixing cavity, achieving the function of fixing the clamp mounting block and the auxiliary fixing clip. When the auxiliary fixing clip is no longer needed for support, the auxiliary fixing clip can be removed and the disassembly thread block is screwed out of the disassembly groove. At this time, the disassembly thread block pulls the disassembly rope to be tensioned. After the disassembly rope is tensioned, the bent end of the elastic strip is pulled back into the extrusion groove. At this time, the elastic strip releases the abutment state with the auxiliary fixing cavity, and then the auxiliary fixing clip is pulled out in the direction away from the clamp mounting block to complete the disassembly. The clamping form is conducive to improving the efficiency of installing the auxiliary fixing clip, and no special tools are required for installation. At the same time, it can be quickly disassembled after use, which further improves the efficiency of the installation and construction of the spare clamp.

[0031] The present invention is further configured as follows: the regulating structure includes:

[0032] Insert the channel and open it on the end face of the clamp fixing sleeve.

[0033] The clamping cavity is provided in the wire clamp fixing sleeve and communicates with the insertion channel.

[0034] The recovery cavity is opened on the inner side of the auxiliary mounting block toward the side of the wire clamp mounting block. The recovery cavity is aligned and connected with the insertion channel.

[0035] The clamping block is arranged in the recovery chamber.

[0036] The pressing part is provided on the auxiliary mounting block and is used to push the clamping block to move into the clamping cavity and clamp the clamping block with the wire clamp fixing sleeve.

[0037] The driving part is arranged in the auxiliary installation block and connected to the clamping block. The driving part is used to recycle the clamping block into the recovery cavity.

[0038] The present invention is further configured as follows: the pressing portion includes:

[0039] The pressing rod is inserted into the auxiliary mounting block along the sliding direction of the wire clamp fixing sleeve, and the pressing rod is inserted through the outer side of the locking groove of the auxiliary mounting block.

[0040] The plug-in cavity is opened in the pressing rod along the axial direction of the pressing rod.

[0041] The spline groove is provided in the pressing rod and is located on the radial side of the plug-in cavity. The spline groove is communicated with the plug-in cavity. The spline groove penetrates the pressing rod toward one end of the clamping block along the axial direction of the pressing rod.

[0042] The plug rod is axially slidable in the plug cavity along the pressing rod, and one end of the plug rod is fixed to the clamping block.

[0043] The connecting block is fixed on the outer side of the plug rod. The connecting block is located in the spline groove and slides in the spline groove along the axial direction of the pressing rod.

[0044] Among them, the axial direction of the pressing rod is the same as the sliding direction of the wire clamp fixing sleeve. The pressing rod can rotate in the wire clamp fixing sleeve. The pressing rod extends into the recovery cavity toward one end of the clamping block, and the plug-in cavity is a divergent inclined surface toward one end of the clamping block.

[0045] The present invention is further configured as follows: the driving unit includes:

[0046] The winding cavity is opened in the auxiliary mounting block.

[0047] The rotating shaft is rotatably arranged in the winding cavity, and one end of the rotating shaft extends to the outside of the auxiliary mounting block.

[0048] The winding wheel is fixed on the rotating shaft.

[0049] One end of the pull rope is wound around the outer curved surface of the winding wheel, and the other end of the pull rope passes through the pressing rod and extends into the plug-in cavity and is fixed to the end of the plug-in rod.

[0050] The rotating disk is fixed to the end of the rotating shaft outside the auxiliary mounting block.

[0051] The rotating handle is fixed on the side of the rotating disk away from the rotating shaft and is located on the eccentric side of the rotating handle.

[0052] The portion where the pull rope passes through the pressing rod forms a movable groove, and the movable groove is opened along the circumference of the pressing rod.

[0053] By adopting the above technical solution, when the position of the hinged tension stranded wire harness needs to be adjusted, the auxiliary mounting block is first placed on the wire clamp mounting block, and the auxiliary mounting block is fixedly connected to the wire clamp mounting block. At this time, the insertion slot and the locking slot are respectively aligned with the two ends of the wire clamp fixing sleeve, and the recovery cavity is aligned with the insertion channel opening. At this time, the pressing rod is pressed toward the direction of the wire clamp mounting block to make the end of the pressing rod abut against the clamping block and push the clamping block into the clamping cavity. At this time, the connecting block is still located in the spline groove, and then the pressing rod is rotated so that the pressing rod drives the plug-in rod to flip through the connection between the spline groove and the connecting block, and then the plug-in rod drives the clamping block to be clamped in the clamping cavity. The clamping block is turned over in the connecting cavity. At this time, the outer contour of the clamping block is misaligned with the inner contour of the insertion channel. The wire clamp fixing sleeve and the clamping block are clamped together. Then, the wire clamp fixing sleeve is pulled out of the wire clamp mounting block through the insertion groove. At this time, the clamping block and the plug rod follow the movement of the wire clamp fixing sleeve and pull the draw rope. After the draw rope is subjected to tension, it drives the winding wheel to rotate, so that the draw rope is unwound from the winding wheel, so that the clamping block can continue to follow the movement of the wire clamp fixing sleeve. When the wire clamp fixing sleeve moves to the connecting bolt, the connecting bolt and the wire clamp fixing sleeve can be threadedly connected by rotating the wire clamp fixing sleeve. When the wire clamp fixing sleeve abuts against the connector, the connection between the wire clamp fixing sleeve and the connecting bolt is completed.

[0054] The pull rope is then pulled back into the reel by the pull rope, and the plug rod is moved back in the direction of the pressing rod, and the clamping block is gradually recovered into the recovery cavity, and the pressing rod is gradually moved outward from the auxiliary mounting block;

[0055] When the clamping block completely enters the recovery cavity, the wire clamp fixing sleeve is completely disconnected from the clamping block and the end of the connecting bolt has extended into the locking groove. At this time, the auxiliary mounting block can be removed from the wire clamp mounting block to complete the installation of the tension stranded wire bundle. By first connecting and fixing the wire clamp fixing sleeve to the connecting bolt, and then using a pull rope to pull the wire clamp fixing sleeve back to the starting position, it can ensure that the two tension stranded wire bundles are respectively connected to the transmission line and the wire clamp mounting block and the redundant length between the transmission line and the wire clamp mounting block remain similar, thereby ensuring that the tension applied by the tension stranded wire bundle to the transmission line on both sides of the wire clamp mounting block is in an approximately equal state, avoiding stress concentration inside the transmission line due to different tensions applied by the tension stranded wire bundle on both sides of the transmission line, which is beneficial to improving the installation quality of the spare wire clamp.

[0056] The present invention is further configured as follows: a limiting cavity is opened in the auxiliary mounting block on the radial side of the pressing rod, the limiting cavity extends along the circumference of the pressing rod, a limiting block is set in the limiting cavity for sliding along the axial direction of the pressing rod, and the end of the limiting block is fixed to the outer side surface of the pressing rod.

[0057] By adopting the above technical solution, the limit block can slide in the limit cavity. When the limit block abuts against the inner wall of the limit cavity, further movement of the pressing rod can be avoided, and the pressing rod can be prevented from completely falling out of the auxiliary mounting block.

At the same time, when the transmission line is broken due to broken strands or metal fatigue, the tension stranded wire bundle can continue to tighten the transmission line and connect to the transmission line, and conduct the current of the transmission line through the wire clamp mounting block to another tension stranded wire bundle, and transmit it to the other broken section of the transmission line. At this time, the current can be conducted through the spare wire clamp, and the tension stranded wire bundle not only shares the tension of the transmission line, but also can temporarily conduct current, reducing the loss caused by the transmission line break accident.

The snap-fit ​​block 41 is slidably arranged in the recovery chamber 40 and can be moved into the snap-fit ​​chamber 43 through the insertion channel 42. The outer contour of the snap-fit ​​block 41 is the same as the inner contour of the insertion channel 42, and the inner contour size of the insertion channel 42 is slightly larger than the outer contour size of the snap-fit ​​block 41. The pressing portion is provided on the auxiliary mounting block 30 for pushing the clamping block 41 into the clamping cavity 43 and engaging the clamping block 41 with the wire clamp fixing sleeve 13. The driving portion is provided in the auxiliary mounting block 30 and connected to the clamping block 41. The driving portion is used to retract the clamping block 41 into the retrieving cavity 40.

[0085] like Figures 2 to 4 As shown, the pressing portion includes a pressing rod 35, an inserting cavity 36, a spline groove 37, an inserting rod 38, and a connecting block 39. The pressing rod 35 is inserted into the auxiliary mounting block 30 through the outer side of the locking groove 32 provided in the auxiliary mounting block 30, and the pressing rod 35 slides along the sliding direction of the wire clamp fixing sleeve 13. The axial direction of the pressing rod 35 is the same as the sliding direction of the wire clamp fixing sleeve 13. The pressing rod 35 can rotate within the wire clamp fixing sleeve 13, and the end of the pressing rod 35 facing the clamping block 41 extends into the recovery cavity 40. The inserting cavity 36 is provided in the pressing rod 35 along the axial direction of the pressing rod 35. The end of the inserting cavity 36 facing the recovery cavity 40 penetrates the pressing rod 35, and the end of the inserting cavity 36 facing the clamping block 41 has a divergent inclined surface. A spline groove 37 is formed in the pressing rod 35 and is located on the radial side of the insertion cavity 36. The spline groove 37 is connected to the insertion cavity 36 and penetrates the pressing rod 35 along the axial direction, pushing the pressing rod 35 toward one end of the clamping block 41. The plugging rod 38 is slidably disposed in the insertion cavity 36 along the axial direction of the pressing rod 35, and one end of the plugging rod 38 is fixed to the clamping block 41. A connecting block 39 is fixed to the outer side of the plugging rod 38. The connecting block 39 is located in the spline groove 37 and slides in the spline groove 37 along the axial direction of the pressing rod 35.

[0086] like Figures 2 to 4As shown, the driving part includes a rotating disk 33, a rotating handle 34, a pull rope 46, a winding cavity 47, a rotating shaft 48 and a winding wheel 49. The winding cavity 47 is opened in the auxiliary mounting block 30, and the rotating shaft 48 is rotatably set in the winding cavity 47. One end of the rotating shaft 48 extends to the outside of the auxiliary mounting block 30. The winding wheel 49 is located on the inner wall of the winding cavity 47 and is fixed on the rotating shaft 48. One end of the pull rope 46 is wound around the outer curved surface of the winding wheel 49. The other end of the pull rope 46 passes through the pressing rod 35 and extends into the plug-in cavity 36 and is fixed to the end of the plug-in rod 38. The part of the pull rope 46 that passes through the pressing rod 35 forms a movable groove 23. The movable groove 23 is opened along the circumference of the pressing rod 35, and the opening angle of the movable groove 23 is less than ninety degrees. The rotating disk 33 is fixed to the end of the rotating shaft 48 located outside the auxiliary mounting block 30, and the rotating handle 34 is fixed to the side of the rotating disk 33 away from the rotating shaft 48 and located on the eccentric side of the rotating handle 34. The rotating handle 34 can be threadedly connected to the end of the external sleeve to extend the length of the rotating handle 34, making it easier for construction workers to rotate the rotating disk 33.

[0087] like Figures 3 and 4 As shown, a limiting cavity 44 is defined within the auxiliary mounting block 30 on the radial side of the pressing rod 35. The limiting cavity 44 extends along the circumference of the pressing rod 35. A limiting block 45 is disposed within the limiting cavity 44, slidingly axially along the pressing rod 35. The end of the limiting block 45 is fixed to the outer side of the pressing rod 35. The limiting block 45 is capable of sliding within the limiting cavity 44. When the limiting block 45 abuts the inner wall of the limiting cavity 44, it prevents further movement of the pressing rod 35, thereby preventing the pressing rod 35 from completely dislodging from the auxiliary mounting block 30.

[0088] First, use the auxiliary fixing clamp 50 to temporarily connect the transmission line 10 to be connected to the wire clamp mounting block 11 and keep it stable, and then install the connecting plate 14 on the wire clamp mounting block 11, and finally install the inner lining stranded wire bundle 18 and the outer partition layer 17 in sequence, and then clamp the transmission line fixing clamp 12 on the outer partition layer 17, and fix the transmission line fixing clamp 12 to the fixing block 15 to complete the fixation of the transmission line 10. This can ensure that the transmission line 10 is in a tensioned state as a whole when the wire clamp is installed. At the same time, the auxiliary fixing clamp 50 can temporarily support the transmission line 10, so that the transmission line 10 is not easy to shake, thereby improving the installation convenience of the spare wire clamp.

[0089] When the end of the auxiliary fixing clip 50 is inserted into the auxiliary fixing cavity 57, the wire clamp mounting block 11 squeezes the elastic strip 52 and retracts it into the extrusion groove 51. When the end of the auxiliary fixing clip 50 is fully inserted into the auxiliary fixing cavity 57, the elastic strip 52 is reset and expanded under the action of elasticity and abuts against the inner wall of the auxiliary fixing cavity 57. At this time, the auxiliary fixing clip 50 cannot be disengaged from the auxiliary fixing cavity 57, achieving the effect of fixing the wire clamp mounting block 11 and the auxiliary fixing clip 50. When the auxiliary fixing clip 50 is no longer needed for support, the auxiliary fixing clip 50 can be removed and the threaded block 50 can be removed. 6 is unscrewed from the disassembly groove 55. At this time, the disassembly threaded block 56 pulls the disassembly rope 54 to be tensioned. After the disassembly rope 54 is tensioned, the bent end of the elastic strip 52 is pulled back into the extrusion groove 51. At this time, the elastic strip 52 is released from the abutment state with the auxiliary fixing cavity 57. Then, the auxiliary fixing clip 50 is pulled out in the direction away from the wire clamp installation block 11 to complete the disassembly. The use of a snap-on form is conducive to improving the efficiency of installing the auxiliary fixing clip 50. No special tools are required for installation. At the same time, it can be quickly disassembled after use, further improving the efficiency of the spare wire clamp installation construction.

[0090] When the position of the hinged tension stranded wire bundle 19 needs to be adjusted, the auxiliary mounting block 30 is first placed on the wire clamp mounting block 11, and the auxiliary mounting block 30 is fixedly connected to the wire clamp mounting block 11. At this time, the insertion slot 31 and the locking slot 32 are respectively aligned with the two ends of the wire clamp fixing sleeve 13, and the recovery cavity 40 is aligned with the opening of the insertion channel 42. At this time, the pressing rod 35 is pressed toward the direction of the wire clamp mounting block 11, so that the end of the pressing rod 35 abuts against the clamping block 41 and pushes the clamping block 41 into the clamping cavity 43. At this time, the connecting block 39 is still located in the spline groove 37, and then the pressing rod 35 is rotated so that the pressing rod 35 drives the plug-in rod 38 to flip through the connection between the spline groove 37 and the connecting block 39, and then the plug-in rod 38 drives the clamping block 41 to flip in the clamping cavity 43. At this time, the outer contour of the clamping block 41 is misaligned with the inner contour of the insertion channel 42, and the wire clamp fixing sleeve 13 is clamped with the clamping block 41. Then, the wire clamp fixing sleeve 13 is pulled out of the wire clamp mounting block 11 through the insertion groove 31. At this time, the clamping block 41 and the plug-in rod 38 follow the movement of the wire clamp fixing sleeve 13 and pull the draw rope 46. After the draw rope 46 is subjected to tension, it drives the winding wheel 49 to rotate, so that the draw rope 46 is unwound from the winding wheel 49, so that the clamping block 41 can continue to follow the movement of the wire clamp fixing sleeve 13. When the wire clamp fixing sleeve 13 moves to the connecting bolt 21, the connecting bolt 21 can be threadedly connected to the wire clamp fixing sleeve 13 by rotating the wire clamp fixing sleeve 13. When the wire clamp fixing sleeve 13 abuts against the connector 20, the connection between the wire clamp fixing sleeve 13 and the connecting bolt 21 is completed.

[0091] After the connection between the wire clamp fixing sleeve 13 and the connecting bolt 21 is completed, the construction personnel rotate the rotating handle 34 to rotate the rotating disk 33, and then the rotating disk 33 drives the winding wheel 49 to rotate through the rotating shaft 48, so that the pull rope 46 is gradually wound onto the winding wheel 49, and then the pull rope 46 is pulled by the connecting rod 38 to reset the clamping block 41 toward the recovery chamber 40, so that the clamping block 41 drives the wire clamp fixing sleeve 13 to move toward the wire clamp mounting block 11. When the wire clamp fixing sleeve 13 re-enters the wire clamp mounting block 11 and abuts against the inner side of the auxiliary mounting block 30, the insertion channel 42 is aligned with the recovery chamber 40 again. Rotate the pressing rod 35 to align the spline groove 37 with the connecting block 39, and press the pressing rod 35 to reinsert the connecting block 39 into the spline groove 37, and then rotate the pressing rod 35 so that the pressing rod 35 drives the clamping block 41 to continue to rotate in the clamping cavity 43 through the plug-in rod 38. When the outer contour of the clamping block 41 is realigned with the inner contour of the insertion channel 42, continue to rotate the rotating disk 33 so that the pull rope 46 continues to wind into the winding wheel 49, and the pull rope 46 pulls the plug-in rod 38 to move back toward the pressing rod 35. The clamping block 41 is gradually recovered into the recovery cavity 40, and the pressing rod 35 gradually moves outward from the auxiliary mounting block 30.

[0092] When the clamping block 41 is fully inserted into the recovery chamber 40, the wire clamp fixing sleeve 13 is completely disconnected from the clamping block 41 and the end of the connecting bolt 21 has extended into the locking groove 32. At this time, the auxiliary mounting block 30 can be removed from the wire clamp mounting block 11 to complete the installation of the tension stranded wire bundle 19. By first connecting and fixing the wire clamp fixing sleeve 13 to the connecting bolt 21 and then using the pull rope 46 to pull the wire clamp fixing sleeve 13 back to the starting position, it is possible to ensure that the two tension stranded wire bundles 19 are connected to the power line 10 and the wire clamp mounting block 11 respectively, and the redundant length between the power line 10 and the wire clamp mounting block 11 remains similar, thereby ensuring that the tension applied by the tension stranded wire bundle 19 to the power line 10 on both sides of the wire clamp mounting block 11 is approximately equal, avoiding stress concentration within the power line 10 due to different tensions applied by the tension stranded wire bundle 19 on both sides of the power line 10, which is conducive to improving the installation quality of the spare wire clamp.

[0101] S8: Use the adjustment structure to pull the wire clamp fixing sleeve 13 back into the wire clamp mounting block 11 through the insertion slot 31. At this time, the end of the connecting bolt 21 is located in the locking slot 32 aligned with the wire clamp fixing sleeve 13.

[0104] In step S6 , the pressing rod 35 is first pressed to press the engaging block 41 into the engaging cavity 43 , and then the pressing rod 35 is rotated to engage the engaging block 41 with the wire clamp fixing sleeve 13 .

[0105] In step S8, the pull rope 46 is wound onto the winding wheel 49 by manually rotating the rotating disk 33, and the wire clamp fixing sleeve 13 is pulled toward the wire clamp mounting block 11 by tension, and finally the wire clamp mounting block 11 is reset. At the same time, the end of the connecting bolt 21 extends into the locking groove 32, and the fixing nut 24 is inserted into the locking groove 32.
