[0021] Aiming at the problem of oxidation or corrosion of insulated wires due to climate influence after the insulation sheath is stripped, this embodiment provides a 10kV live wire manual repair tool. Figure 1 and Figure 2 As shown, the 10kV live working conductor manual repair tool includes a mounting base 1, a rubber-coated hose clamp 2, a multi-link structure 3, an insulating operating rod 4 and an operating handle 5; wherein, the multi-link structure 3 is located in the mounting base 1, and the multi-link structure 3 is two sets of connecting rod structures arranged symmetrically; one end of the two sets of connecting rod structures extends to the outside of a set of mounting base plates 7, and is installed with relatively arranged rubber-coated hose clamps 2, and the other end is hinged on the mounting base plate 7; one end of the insulating operating rod 4 is detachably connected to the mounting base 1, and the inside of the insulating operating rod 4 is hollow and is provided with a traction rope 6; one end of the traction rope 6 passes through the insulating operating rod 4 and extends into the mounting base 1, and is connected to the middle of the two sets of connecting rod structures through a joint, and the other end passes through the tail end of the insulating operating rod 4 and is connected to the operating handle 5.

[0022] like Figure 2As shown, when using the 10kV live conductor manual repair tool, one hand holds the tail end of the insulating operating rod 4 and the other hand slightly pulls the operating handle 5; after slightly pulling the operating handle 5, the operating handle 5 controls the relatively arranged rubber-covered hose clamp 2 through the traction rope 6 and the multi-link structure 3 to form a Figure 2 After applying the special glue 12, the 10kV live wire manual repair tool is moved to the insulation stripping position of the insulated wire 15 by the insulating operating rod 4. After the insulated wire 15 is located in the middle of the set of relatively set rubber-coated pipe clamps 2, the operating handle 5 is pulled hard. The operating handle 5 controls the relatively set rubber-coated pipe clamps 2 to move in a certain direction through the traction rope 6 and the multi-link structure 3. Figure 3 After the special glue 12 solidifies, the operating handle 5 is released, and the pair of oppositely arranged rubber-coated pipe clamps 2 automatically return to the separated state shown in Figure 4. At this time, the special glue 12 solidifies at the point where the insulation of the insulated wire 15 is stripped, forming a protective layer, preventing the metal wires in the insulated wire 15 from oxidation or corrosion due to weathering.

[0023] Furthermore, in order to realize the above working principle, the mounting base 1, the rubber-coated hose clamp 2, the multi-link structure 3, the insulating operating rod 4 and the operating handle 5 in this embodiment adopt the following specific structure:

[0024] Mounting seat 1: Figure 1 and Figure 2 As shown, the mounting seat 1 in this embodiment includes a group of mounting base plates 7, which are arranged at intervals, and the gaps between the group of mounting base plates 7 are used for the installation of the multi-link structure 3; the rear ends of the group of mounting base plates 7 are formed with connecting ends 8 that can be connected to the insulating operating rod 4; in order to ensure the safety of the use of the 10kV live working conductor manual repair tool, the mounting seat 1 is made of insulating material as a whole.

[0025] Multi-link structure 3: Figure 2 、 Figure 3 and Figure 4 As shown, each group of link structures of the multi-link structure 3 includes a support arm 9 and an opening control rod 10. One end of the support arm 9 extends to the outside of a group of mounting base plates 7 and is installed with a rubber-coated hose clamp 2, and the other end is hingedly installed between a group of mounting base plates 7 through a shaft, and is close to the side of the connecting end 8 of the mounting base 1. One end of the opening control rod 10 is hinged to the middle section of the support arm 9 through a shaft, and the other ends of the two groups of opening control rods 10 extend to the central axis of the mounting base 1 and are connected to the joint at one end of the traction rope 6 through a shaft. In order to ensure the safety of the use of the 10kV live working conductor manual repair tool, the multi-link structure 3 is made of insulating materials, except for the shaft made of metal material, and the support arm 9 and the opening control rod 10 are made of insulating materials.

[0026] In order to minimize the distance between a set of mounting base plates 7, as shown in FIG. Figure 2 、 Figure 3 and Figure 4 As shown, in this embodiment, the middle section of the support arm 9 is provided with a mounting slot 11 that is hingedly connected to the opening control lever 10. One end of the opening control lever 10 is hingedly mounted to the mounting slot 11 in the middle section of the support arm 9 via a shaft. The provision of the mounting slot 11 not only reduces the spacing between a set of mounting base plates 7, but also limits the maximum opening angle of a single support arm 9.

[0027] When the joint is stressed, the other ends of the two sets of opening control rods 10 change with the position of the joint. Figure 3 As shown, when the joint is forced to move toward the side of the insulating operating rod 4, the two sets of opening control rods 10 pull the support arm rod 9, so that the end of the support arm rod 9 extending outside the installation base plate 7 is closed toward the middle, thereby achieving the closure of a set of relatively set rubber-coated hose clamps 2. Figure 4 As shown, when the joint is forced to move forward, the two sets of opening control rods 10 pull the support arm rod 9, so that the end of the support arm rod 9 extending outside the mounting base plate 7 opens outward, thereby realizing the separation of a set of relatively arranged rubber-coated hose clamps 2.

[0028] In addition, due to the process of the joint being forced to move forward, if the tension of the traction rope 6 is relied upon alone, the stable realization of the outward extension of a set of support arm rods 9 cannot be guaranteed. Figure 2 、 Figure 3 and Figure 4 As shown, in this embodiment, a mounting hole 13 that matches the joint is further provided in the connecting end 8 of the mounting base 1, and a spring 14 is provided in the mounting hole 13, and both sides of the spring 14 are in contact with the inner wall of the mounting hole 13 and the joint respectively; the restoring force of the spring 14 is used to push the joint forward to ensure the stable realization of the outward extension action of a set of support arm rods 9.

[0029] Rubber hose clamp 2: Figures 1 to 4 As shown, the rubber-coated hose clamp 2 in this embodiment is made of an insulating material with low adhesion to the special adhesive 12. The rubber-coated hose clamp 2 is formed into an arc-shaped plate structure. The advantages of using an arc-shaped plate structure are: first, the special adhesive 12 can be applied to the inner wall of the arc-shaped plate structure; second, a set of arc-shaped plates can be closed to clamp the insulated wire 15. A connecting plate is formed on the outer wall of the arc-shaped plate structure, which is fixedly connected to one end of the support arm 9 via the connecting plate.

[0030] Insulating operating rod 4: The insulating operating rod 4 is a secondary modification of the commercially available finished insulating operating rod 4. The T-head at the front end of the insulating operating rod 4 is removed, and a threaded hole that is compatible with the connecting end 8 of the mounting seat 1 is processed at the front end; at the same time, an external thread is processed on the outer surface of the connecting end 8 of the mounting seat 1 so that the connecting end 8 of the mounting seat 1 and the insulating operating rod 4 can be threadedly connected.

[0031] In addition, since the interior of the commercially available finished insulating operating rod 4 is hollow, it is also convenient to lay out the traction rope 6. One end of the traction rope 6 passes through the insulating operating rod 4 and extends into the mounting seat 1, and is fixedly connected to the joint at the mounting hole 13 in the mounting seat 1; the other end of the traction rope 6 passes through the hole punched at the tail end of the insulating operating rod 4 and is fixedly connected to the operating handle 5.

[0032] To sum up, the opening and closing of the relatively arranged rubber-coated hose clamp 2 is controlled by the operating handle 5 through the traction rope 6 and the multi-link structure 3, and the special glue 12 is coated on the inner wall of the rubber-coated hose clamp 2, so that the special glue 12 is solidified at the place where the insulation sheath of the insulated wire 15 is stripped to form a protective layer, thereby preventing the metal wire in the insulated wire 15 from being oxidized or corroded by the weather.

[0033] The above are only preferred specific implementation methods of the present invention, but the protection scope of the present invention is not limited to them. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention within the technical scope disclosed by the present invention, and they should be covered by the protection scope of the present invention.
