Description

Technical Field

[0001] This invention belongs to the field of power grid technology, and specifically relates to a self-locking wiring tool. Background Technology

[0002] High-altitude wiring clamps are specialized tools used for temporary wiring during the maintenance and testing of high-voltage equipment in power systems. They are suitable for testing and wiring high-altitude equipment from the ground. They transfer traditional high-altitude work to the ground, greatly improving on-site working conditions and enhancing safety and efficiency. However, currently used high-altitude wiring clamps have the following problems: the opening and closing of the clamps requires manual control with an additional operating lever. This design increases the number of steps, making it cumbersome and inefficient. Furthermore, the accuracy and reliability of manual opening and closing may be affected by the operator's skill level. Existing clamps lack automated control during opening and closing, failing to achieve self-locking and requiring manual intervention. This not only affects operational efficiency but may also pose safety hazards. Summary of the Invention

This improves the automation level of the wiring tool, increases work efficiency, ensures operator safety, and enhances operational accuracy and reliability. Furthermore, the integrated wiring component simplifies the wiring process, ensuring convenience and operational flexibility while reducing cumbersome wiring steps. Attached Figure Description

[0035] To resolve the above issues, please refer to [link / reference]. Figures 1 to 9A self-locking wiring tool of the present invention includes a clamping assembly 1, a self-locking assembly 2, and a tool body 3. The clamping assembly 1 includes a fixed end 11 and a movable end 12, the fixed end 11 and the movable end 12 being disposed opposite to each other and forming a clamping space 13 for clamping a high-voltage wire. The self-locking assembly 2 includes a trigger 21 and a self-locking part 22. One end of the trigger 21 is movably connected to the fixed end 11, and the other end is a free end and is limited by a limiting groove 23, the limiting groove 23 being disposed on the movable end 12. One end of the self-locking part 22 is connected to the movable end 12. The clamping assembly 1 is connected to the tool body 3, and the fixed end 11 is located at the end of the clamping assembly 1 away from the tool body 3. A self-locking part 22 is provided between the tool body 3 and the clamping assembly 1. The free end is limited to the limiting groove 23. When the clamping assembly 1 is in the open state, the high-voltage wire is inserted into the clamping space 13. The free end disengages from the limiting groove 23, grips the tool body 3, and is pulled. The movable end 12 moves towards the fixed end 11 through the self-locking part 22, and the clamping assembly 1 is in a self-locking state. The trigger 21 is connected to the fixed end 11 via a spring shaft, ensuring that the trigger 21 always has the force to drive its free end to rotate to the limiting groove 23, thus achieving automatic reset of the trigger 21. The limiting groove 23 has an "L" shape, which restricts the rotation direction of the trigger 21.

[0036] In optional embodiments, such as Figure 7 and Figure 8 As shown, the self-locking part 22 includes a limiting shaft 224, a fixed pulley 221, and a pull rope 222. The limiting shaft 224 is located at the end of the tool body 3 facing the clamping assembly 1 and is connected to the tool body 3. A limiting plate 225 is provided at the end of the limiting shaft 224 away from the tool body 3. The fixed pulley 221 is located at the end of the clamping assembly 1 away from the tool body 3. One end of the pull rope 222 and part of the clamping assembly 1 are connected to the surface of the limiting plate 225 away from the tool body 3, and the other end is wound around the fixed pulley 221 and connected to the movable end 12. Specifically, the limiting shaft 224 and the movable end 12 are connected by the pull rope 222 and the fixed pulley 221, and the tool body 3 is gripped and lowered, causing the movable end 12 to move towards the fixed end 11, realizing the automatic closing of the clamping assembly 1. At the same time, the fixed pulley 221 can improve the smoothness of the automatic closing of the clamping assembly 1.

[0037] In optional embodiments, such as Figures 1 to 8As shown, the self-locking part 22 also includes a spring 223, which is sleeved on the limiting shaft 224. One end of the spring 223 is connected to the surface of the limiting plate 225 facing the tool body 3, and the other end is connected to the end of the tool body 3. The spring 223 provides cushioning for the clamping assembly 1 to prevent damage to the clamping assembly 1.

[0038] In optional embodiments, such as Figures 1 to 8 As shown, the clamping assembly 1 also includes a first housing 14 and a second housing 15. The fixed end 11 is connected to the second housing 15, and the movable end 12 moves along the height direction of the second housing 15 through the self-locking part 22. The first housing 14 is connected to the end of the self-locking part 22 away from the tool body 3. The second housing 15 is rotatably connected to the first housing 14 and is set at an angle to the first housing 14. Specifically, the fixed pulley 221 is disposed on the second housing 15. The cross-section of the second housing 15 is "]" shaped, forming an opening. The side of the second housing 15 with the opening is provided with a fixed end 11, a movable end 12, and the fixed pulley 221. The surface of the second housing 15 opposite to the opening is connected to the first housing 14 by a screw 4. The first housing 14 is connected to a limiting plate 225. The second housing 15 rotates relative to the first housing 14 by the screw 4. The angle between the two can be adjusted according to maintenance or testing requirements. The cross-section of the first housing 14 is "L" shaped. The first housing 14 is disposed on the periphery of the second housing 15. The L-shaped structure of the first housing 14 can limit the rotation direction of the second housing 15. Furthermore, the first housing 14 and the second housing 15 are made of insulating plastic material, which has good insulation and strength. The second housing 15 can be designed as a split type, which facilitates the installation of the fixed pulley 221 and the pull rope 222.

[0039] In optional embodiments, such as Figure 8 As shown, the second housing 15 has a limiting hole 151, which is correspondingly arranged with the fixed pulley 221. One end of the pull rope 222 is connected to the spring 223, and the other end passes through the limiting hole 151 along the side wall of the second housing 15, is wound around the fixed pulley 221, and is connected to the movable end 12.

[0040] In optional embodiments, such as Figure 1 As shown, the surfaces of the movable end 12 and the fixed end 11 that are opposite each other are arc-shaped. The arc-shaped structures of the fixed end 11 and the movable end 12 match the shape of the high-voltage line, so that the fixed end 11 and the movable end 12 fit snugly and clamp the connection point of the high-voltage line, further improving the connection stability between the fixed end 11 and the movable end 12 and the high-voltage line.

[0041] In optional embodiments, such as Figure 1As shown, the surfaces of the movable end 12 and the fixed end 11 opposite each other are provided with anti-slip textures 16. When the high-voltage wire is inserted into the clamping space 13, the movable end 12 moves toward the fixed end 11 through the self-locking component 2, so that the high-voltage wire is stably connected in the clamping space 13. The anti-slip textures 16 can further improve the clamping stability of the clamping component 1, making it difficult for the clamping component 1 to shift to the corresponding connection point.

[0042] In optional embodiments, such as Figure 1 and Figure 9 As shown, it also includes a wiring assembly 5, which is used to connect two adjacent wiring tools. The two wiring tools are connected in series through the wiring assembly 5 to form an integrated structure, which reduces the difficulty of construction, simplifies the wiring method, and ensures the personal safety of workers when working at heights.

[0043] In optional embodiments, such as Figure 1 and Figure 9 As shown, the wiring assembly 5 includes a take-up box 51, a first connecting terminal 52, a second connecting terminal 53, and a wire 54. The take-up box 51 is disposed on the periphery of the tool body 3. The first connecting terminal 52 is disposed on the fixed end 11, and the second connecting terminal is disposed on the movable end 12. One end of the wire 54 is connected to the second connecting terminal, and the other end is partially wound around the take-up box 51 and connected to the first connecting terminal 52 of another wiring tool. By setting up a cable retractor 51 to store the wire 54, it is convenient to connect two adjacent wiring tools. When the connection points are far apart, the length of the wire 54 can be adjusted according to the distance between the two connection points, eliminating the need for separate wiring, simplifying the operation process. The integrated wiring solution reduces cumbersome wiring steps, shortens preparation and operation time, and ensures the convenience of wiring and the flexibility of operation. After the equipment maintenance and testing are completed, the wire 54 is automatically retracted into the cable retractor 51. Furthermore, the first connecting terminal 52 and the second connecting section are crimp-type banana plug terminals, which can both crimp and fix the wire 54 and insert the banana plug. The telescopic length of the wire 54 is within 5 meters, which can meet the needs of different scenarios and different connection point distances.

[0044] In optional embodiments, such as Figures 1 to 8 As shown, the tool body 3 is a telescopic structure. The tool body 3 is mainly used by the worker to grip and deliver the wiring assembly 5 to the high-voltage line. The telescopic structure of the tool body 3 can quickly and automatically adjust its length according to the height of the high-voltage line, saving disassembly and assembly time and improving work efficiency. Specifically, the tool body 3 is a telescopic rod, which is composed of multiple rod sections connected in a movable manner. The rod sections are made of insulating material, which improves the safety performance of the wiring tool.

[0045] Before clamping the high-voltage wire, the free end of the trigger 21 is confined within the limiting groove 23, keeping the clamping assembly 1 in the open state. During use, the operator grasps the end of the tool body 3 furthest from the clamping assembly 1, raising the clamping assembly 1 to align with the connection point and height of the high-voltage wire. The high-voltage wire is then pressed into the clamping assembly 1, pushing the trigger 21 and causing it to disengage from the limiting groove 23. The operator then pulls the tool body 3, causing the movable end 12 to move along the length of the second housing 15 towards the fixed end via the action of the fixed pulley 221, the pull rope 222, the spring 223, and the limiting shaft 224. When the fixed end 11 is brought together, the clamping component 1 is in a self-locking state, realizing the automatic closing of the clamping component 1 and clamping the high-voltage line; after maintenance or testing, the staff grasps the tool body 3 and pushes the wiring tool away from the ground, the movable end 12 moves away from the fixed end 11, and the trigger 21, through the action of the spring shaft, its free end falls into the limiting groove 23, the clamping component 1 changes from the self-locking state to the open state, so that the high-voltage line is released from the clamping component 1 for removal, and the wiring component 5 connects multiple wiring tools in series and automatically adjusts the length of the wire 54 according to the different spacing of the wiring points.

[0046] In summary, by setting the self-locking component 2 and the clamping component 1, the wiring tool achieves self-locking clamping of the high-voltage wire, so that the free end of the trigger 21 is limited to the limiting groove 23, the movable end 12 cannot move, the clamping component 1 is in the open state, after the high-voltage wire is pressed into the clamping space 13, the free end of the trigger 21 disengages from the limiting groove 23, the operator pulls the tool body 3, driving the movable end 12 to move towards the fixed end 11 and clamp the high-voltage wire under the action of the spring 223, the pull rope 222 and the fixed pulley 221, thereby improving the automation level of the wiring tool, increasing work efficiency, ensuring the personal safety of the operator, and improving the operational accuracy and reliability; the wiring component 5 realizes integrated wiring, simplifies the wiring process, ensures the convenience of wiring and the flexibility of operation, and reduces cumbersome wiring steps.
