[0022] The embodiment of the present invention provides a 10KV overhead line in-span insulating rod method conductor tightening device, which is used for connecting conductors in the span, and includes: a telescopic member 100; a fixing member 200, which is symmetrically arranged at both ends of the telescopic member 100, and the fixing member 200 is used to fix the conductor; an insulating rod, which is movably arranged at one end of the fixing member 200; a clamping member 300, which is symmetrically arranged on both sides of the fixing member 200, and the clamping member 300 is used to clamp the conductor. The use of the insulating rod effectively isolates the contact between the operator and the high-voltage conductor, significantly reducing the risk of electric shock. The operator can complete the operation within a safe distance to ensure personal safety. The fixing member 200 is symmetrically arranged at both ends of the telescopic member 100, which can firmly fix the conductor and avoid short circuit or arc phenomenon caused by loose conductor. The device can be easily operated by a single person, reducing the demand for manpower and shortening the construction time. The telescopic member 100 can be flexibly adjusted according to the span, so as to quickly adapt to different working environments. The movable setting of the insulating rod allows for flexible adjustment and easy operation when working at different angles and positions.

[0023] In some embodiments, the telescopic member 100 includes a telescopic rod 110 and a driving member 120, wherein the telescopic rod 110 is arranged at the output end of the driving member 120, and the driving member 120 is used to drive the telescopic rod 110 to extend and retract. The driving member 120 can accurately control the telescopic length of the telescopic rod 110, allowing rapid adjustment according to different working environments and specific positions of the wires. Through the control of the driving member 120, the operator can complete the adjustment of the telescopic rod 110 only through a simple switch or controller, reducing the complexity of manual adjustment. The driving member 120 can quickly realize the telescopic extension of the telescopic rod 110, reducing the waiting time, thereby speeding up the speed of tightening and connecting the wires. This rapid response can effectively improve construction efficiency and shorten the construction period. The telescopic rod 110 is arranged at the output end of the driving member 120, making the entire structure more stable. Even during high-intensity operation, the telescopic rod 110 can remain stable, reducing operational errors caused by instability. With the help of the driving member 120, the operator no longer needs to apply too much physical force to adjust the telescopic rod 110, thereby reducing labor intensity. This can effectively reduce worker fatigue and improve work comfort during long-term operations. The drive member 120 can be electrically controlled, and the operator can complete the operation at a safe distance, further improving safety in high-voltage environments and reducing the risk of electric shock and other accidents. The drive member 120 can achieve precise control of the telescopic rod 110, making it easier to handle subtle adjustments and helping to achieve higher quality construction results.

[0024] Specifically, the driving member 120 is a parasol-shaped transmission gear, so as to drive the length adjustment of the telescopic rod 110. Other transmission modes can also be used as long as the telescopic effect can be achieved.

[0025] In some embodiments, the telescopic member 100 further includes a power rod, which is made of insulating material. The power rod is connected to the telescopic rod 110 through the driving member 120, and the power rod provides power for the driving member 120. The power rod is directly connected to the telescopic rod 110 through the driving member 120, ensuring that the power transmission is more efficient, reducing energy loss, and enabling the telescopic rod 110 to be quickly and stably extended and retracted. The power rod can increase the overall stability of the system, reduce vibration during operation, thereby improving work accuracy and ensuring the quality of wire tightening. The power rod can adapt to a variety of power sources, such as electric, pneumatic, etc., providing flexibility so that the device can operate efficiently in different environments. By concentrating the power source through the power rod, the operation process can be simplified, making it easier for the operator to control and improving work efficiency. The addition of the power rod reduces the burden on the driving member 120, reduces the risk of failure caused by overload, and improves the reliability and durability of the entire device. The power rod provides continuous power to ensure that the telescopic rod 110 can maintain smooth movement throughout the operation, reduce stagnation and resistance, and improve the smoothness of operation.

[0026] In some embodiments, the fixing member 200 includes a first mounting member 210 and an adjusting member 220. The first mounting member 210 is provided with a first mounting hole, the first mounting hole is movably mounted on the telescopic rod 110, and the adjusting member 220 is movably connected to the first mounting member 210. The adjusting member 220 is used to fix the position of the fixing member 200. The first mounting hole is movably mounted on the telescopic rod 110, and the first mounting member 210 is freely movable on the telescopic rod 110, so that the adjustment of the installation position is more flexible. The movably connected adjusting member 220 and the first mounting member 210 enable the position of the fixing member 200 to be fixed by the adjusting member 220 after determining the appropriate position, thereby ensuring stability. The adjusting member 220 allows the operator to adjust and fix the position conveniently and quickly, reducing the time for installation and debugging, and improving work efficiency, especially when the position needs to be adjusted frequently. Through the fixing effect of the adjusting member 220, it is ensured that the fixing member 200 will not loosen or slide during use, thereby reducing the safety hazards caused by the instability of the device, especially during high-altitude or high-pressure operations. Unnecessary complex structures are reduced, making the overall structure of the device simpler and clearer, and easier to maintain and overhaul.

[0027] In some embodiments, the fixing member 200 further includes a second mounting member 230 and a switch member 240, the second mounting member 230 is provided with a second mounting hole, the second adjusting member 220 is movably connected to the second mounting member 230, and the switch member 240 is used to switch the open state and the closed state of the second mounting hole. The second mounting member 230 is provided with a second mounting hole, allowing the device to be installed in different positions. The switch member 240 is used to switch the open state and the closed state of the second mounting hole, so that the operator can quickly and conveniently control the use of the fixing member 200. Through the control of the switch member 240, the stability of the second mounting hole during use can be ensured to prevent accidental loosening or displacement, especially when carrying a load or being affected by external forces.

[0028] In some embodiments, an insulating interface 410 is also included, and the insulating interface 410 is fixedly connected to the telescopic rod 110, and the insulating rod is movably connected to the telescopic rod 110 through the insulating interface 410. The insulating interface 410 is made of high-strength materials with excellent insulation properties, such as ceramics, high-performance resins or special composite materials. These materials can not only effectively isolate the current and prevent the risk of electric shock, but also withstand certain mechanical stress and impact to ensure the stability and durability of the connection. The interface includes a precise matching surface, a locking mechanism and a necessary guide structure to ensure that the insulating rod can be smoothly and accurately connected and locked in a predetermined position. The active connection between the insulating rod and the telescopic rod 110 through the insulating interface 410 allows the operator to adjust the length or angle of the insulating rod according to actual work requirements. The connection method can be achieved through a variety of mechanisms such as thread rotation, snap lock, sliding guide rail, etc., each mechanism is designed to simplify operation, improve efficiency and enhance safety. The existence of the insulating interface 410 greatly improves the safety of the entire system. The insulating rod connected through the insulating interface 410 can effectively isolate harmful factors such as current, heat radiation, chemical corrosion, etc., protecting the operator from harm. In addition, the rugged design and easy replacement of the insulating interface 410 also reduce safety risks caused by aging or damage of the equipment.

[0029] In some embodiments, the clamping member 300 includes a fixed plate 310 and a limiting portion, one end of the fixed plate 310 is connected to the telescopic rod 110, and the other end of the fixed plate 310 is movably connected to the limiting portion. One end of the fixed plate 310 is connected to the telescopic rod 110, and this design provides a stable foundation so that the fixed plate 310 can maintain a stable position on the telescopic rod 110. The other end of the fixed plate 310 is movably connected to the limiting portion, which enhances the stability and reliability of the overall structure. The movable connection between the fixed plate 310 and the limiting portion enables the operator to adjust the position of the fixed plate 310 as needed. The limiting portion can prevent the fixed plate 310 from excessive movement and ensure that it operates within a certain range. The clamping member 300 makes the installation process relatively simple, and the operator can quickly complete the connection and adjustment of the fixed plate 310 and the limiting portion. At the same time, the existence of the limiting portion makes maintenance work easier without frequent adjustment.

[0030] In some embodiments, the limiting part includes a first limiting device 320 and a second limiting device 330, the first limiting device 320 and the second limiting device 330 are arranged in parallel, and the first limiting device 320 and the second limiting device 330 cooperate with each other to form a clamping groove 340, and the clamping groove 340 is used to clamp the wire. The first limiting device 320 and the second limiting device 330 are arranged in parallel to form a stable structure, which ensures that the positioning of the wire can be effectively maintained during use and reduces the displacement caused by vibration or external force. The clamping groove 340 formed by the mutual cooperation of the first limiting device 320 and the second limiting device 330 is specifically used for clamping the wire. The clamping groove 340 makes the installation and removal of the wire more convenient, and the operator can operate quickly, which improves the work efficiency. At the same time, the limiting part also makes the subsequent maintenance work easier. By effectively fixing the wire, the limiting part can reduce the risk of short circuit caused by the movement of the wire, especially in a high current environment, and improves the safety of the system. The limiting part uses wear-resistant and corrosion-resistant materials to ensure its durability in long-term use and reduce the replacement frequency.

[0031] Specifically, the first limiting device 320 is an L-shaped structure, the second limiting device 330 and the first limiting device 320 form a snap-in groove, and the structure of the second limiting device 330 is a quadrilateral structure. During use, the snap-in groove is in an open state, is sleeved on the wire and tightened.

[0032] In some embodiments, the clamping member 300 further includes a fastener 350, one end of which is connected to the fixing plate 310, and the other end of which is connected to the first limiting device 320, and the fastener 350 is used to adjust the diameter of the clamping slot 340. One end of the fastener 350 is connected to the fixing plate 310, and the other end is connected to the first limiting device 320. This structure ensures that the fastener 350 can stably connect the two components and provide support for the function of the entire clamping member 300. The main function of the fastener 350 is to adjust the diameter of the clamping slot 340. The operator can easily change the size of the clamping slot 340 by rotating or moving the fastener 350 to adapt to wires or other components of different diameters. By adjusting the fastening degree of the fastener 350, the fixing effect of the clamping slot 340 on the wire can be effectively enhanced to prevent the wire from loosening or shifting under vibration or external force. Different wire diameters can be easily adapted by adjusting the fastener 350, so that the clamping member 300 can be widely used in various devices and scenarios, improving its versatility.

[0033] A 10KV overhead line internal insulation rod method conductor tightening method is used to control the 10KV overhead line internal insulation rod method conductor tightening device as mentioned above to connect the internal span conductor. The 10KV overhead line internal insulation rod method conductor tightening method comprises: unfolding a telescopic rod 110 through an insulating rod; clamping a clamping piece 300 on one side of the insulating rod to connect the conductor, and further fixing the conductor with a fixing piece 200 on one side of the clamping piece 300; sleeve the fixing piece 200 on the other side on the conductor through the insulating rod, and fix the position through the clamping piece 300; cut off the conductor that needs to be repaired, and install a conical quick connection tube by controlling the telescopic rod 110; release the position of the clamping piece 300 and the fixing piece 200, and perform insulation restoration on the exposed connection point.

[0034] The workflow is as follows: 1. Expand the telescopic rod 110 First, the operator slowly unfolds the telescopic rod 110 through the insulating rod. This step needs to ensure that the telescopic rod 110 is stable during the entire operation to avoid unexpected risks caused by improper operation.

[0035] 2. Card-connected wire The force of the insulating rod is used to firmly clamp the clamping member 300 on one side onto the wire. At this time, the operator needs to ensure that the clamping member 300 is in good contact with the wire to avoid slipping or loosening in subsequent operations.

[0036] On one side of the clamping member 300, the operator further fixes the fixing member 200 to ensure that the wire does not move during the entire process. This process can enhance the stability of the wire and lay a solid foundation for subsequent operations.

[0037] 3. Install the other side fixing piece 200 Through the insulating rod, the operator accurately sleeves the fixing member 200 on the other side on the wire. At this time, the position needs to be carefully adjusted to ensure that the fixing member 200 can be accurately fixed and form an effective clamping force with the clamping member 300 on the front side.

[0038] Once the fixing member 200 is in place, the operator needs to reconfirm the fixing position through the clamping member 300 to ensure the stability of the entire wire and prevent displacement caused by vibration or other factors under high-voltage environment.

[0039] 4. Cut off the inspection wire After the wire is fixed, the operator cuts off the wire section that needs to be repaired. At this time, it is important to pay attention to the safety of the surrounding environment, ensure that the cutting tool is used properly, and avoid sparks or other safety hazards.

[0040] 5. Install the tapered quick-connect pipe The conical quick-connector tubes are accurately installed on both ends of the cut wire by controlling the telescopic rod 110. The conical design can ensure good connection of the wires, reduce contact resistance, and ensure smooth passage of current.

[0041] 6. Release the clamping member 300 and the fixing member 200 After the installation of the connecting pipe is completed, the operator carefully releases the position of the clamping member 300 and the fixing member 200. At this time, the stability of the insulating rod needs to be maintained to ensure that the wire will not be unnecessarily displaced or loosened when the pressure is released.

[0042] 7.Insulation restoration Restore the insulation of the exposed joints. You can use insulating tape or heat shrink tubing to ensure that the insulation performance of the joints meets safety standards.

[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the present invention can still be modified or replaced by equivalents.
