[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] Example 1

[0029] Reference Figure 1 , this embodiment provides an auxiliary disassembly structure.

[0030] The support mechanism 100 is used to provide the most basic support structure for the auxiliary disassembly structure. A matching rod 102 is vertically arranged on the top of the stabilizing rod 101, and the stabilizing rod 101 and the matching rod 102 are arranged in an L shape.

[0031] The opening and closing mechanism 200 is used to control the opening or closing of the auxiliary disassembly structure. The outer wall sliding sleeve of the stabilizing rod 101 is provided with a main moving part 201, and the bottom of the main moving part 201 is provided with a disassembly claw 202. The side wall handle of the disassembly claw 202 is fixedly connected to the main moving part 201. When the main moving part 201 starts to slide along the outer wall of the stabilizing rod 101, the side wall handle of the disassembly claw 202 can move with the main moving part 201, thereby realizing the opening and closing of the disassembly claw 202 itself.

[0032] An elastic contraction part 203 is provided on the other side of the handle of the disassembly claw 202. The elastic contraction part 203 can be a spring. When the side wall handle of the disassembly claw 202 moves with the main moving part 201, it can drive the elastic contraction part 203 to compress or extend, thereby providing a reverse reset elastic force, which helps to return the structure to its original position after the disassembly work is completed, and is convenient for the staff to operate. A variety of additional structures can be adaptively installed on the matching rod 102, such as extending the operating rod, to facilitate the staff to carry out aerial construction, etc.

[0033] After the disassembly claw 202 realizes the opening and closing movement, the insulator at the overhead conductor can be disassembled and maintained. Compared with the conventional disassembly and assembly with hand-held pliers, it is safer and improves the working efficiency.

[0034] Example 2

[0035] Reference Figures 1 to 3 This embodiment is based on the previous embodiment, and is different from the previous embodiment in that:

[0036] The outer wall of the matching rod 102 is also slidably sleeved with a secondary moving part 204, and a movable rod 205 is arranged between the secondary moving part 204 and the main moving part 201, and the two ends of the movable rod 205 are respectively rotatably connected with the secondary moving part 204 and the main moving part 201. When the secondary moving part 204 starts to move linearly along the outer wall of the matching rod 102, it can push the other end of the movable rod 205 to drive the main moving part 201 to move linearly along the outer wall of the stabilizing rod 101, thereby driving the disassembly claw 202 to realize the opening and closing movement, and the insulator at the overhead wire can be disassembled and maintained.

[0037] A connecting sleeve 101a is fixedly provided on the top of the stabilizing rod 101, and the other end of the connecting sleeve 101a is connected to the matching rod 102. The connecting sleeve 101a can ensure that the stabilizing rod 101 and the matching rod 102 are stably arranged in an L-shaped configuration. An elastic reset member 101a-1 is fixedly provided on the side of the connecting sleeve 101a facing the auxiliary moving member 204. The elastic reset member 101a-1 can be a spring. When the auxiliary moving member 204 moves linearly along the matching rod 102, it can also drive the elastic reset member 101a-1 to be compressed or stretched, thereby imparting a reset elastic force.

[0038] The end thread of the mating rod 102 is screwed together with a transfer end 102a, which can realize linear motion along the mating rod 102 while rotating along the thread. The movement direction of the thread-controlled transfer end 102a can be set to clockwise control forward movement or counterclockwise control forward movement. When the transfer end 102a moves forward, it can push the auxiliary moving part 204 to follow the movement, thereby realizing the effect of the linkage movable rod 205 controlling the opening and closing of the disassembly claw 202.

[0039] The other end of the adapter terminal 102a is fixedly provided with an operating lever 102a-1, and the length of the operating lever 102a-1 can be freely controlled, so that the staff can rotate the operating lever 102a-1 from a long distance to drive the adapter terminal 102a forward or backward to achieve the effect of controlling the opening and closing of the disassembly claw 202. The end of the operating lever 102a-1 is also fixedly provided with an auxiliary dial head 102a-2, which can be used to cooperate with the staff to realize appropriate dialing and adjustment of the surrounding structure to meet the different environmental requirements of the construction site.

[0040] Example 3

[0041] Reference Figures 1 to 5 This embodiment is based on the previous embodiment, and is different from the previous embodiment in that:

[0042] The stabilization mechanism 300 is used to solve the connection and installation problems of composite insulators on the conductor side. It solves the gap in replacing 110kV tension composite insulators at ground potential during live work, providing more possibilities for live maintenance work.

[0043] There are two stabilizing triangles 301, which are fixedly connected to the left and right wires respectively. The space between the two stabilizing triangles 301 is used to accommodate other structures of the stabilizing mechanism 300. Two mounting holes 301a are provided on the surface of the stabilizing triangle 301. Each mounting hole 301a is used for the insulator on the corresponding side. The connecting plate 302 is fixedly arranged between the two stabilizing triangles 301. By adjusting the telescopic assembly 303 on one side of the connecting plate 302, the length of the connecting plate 302 can be increased slightly, thereby pulling the corresponding stabilizing triangle 301 and the corresponding wire on the right side to the left. Since the insulator is subjected to not only longitudinal and lateral forces, but also its own weight, this creates great difficulties in installing and removing the insulator string. Therefore, this method can effectively transfer the force on the insulator.

[0044] A docking block 301a-1 is fixedly inserted into the mounting hole 301a of one of the stabilizing triangle plates 301, and the other side of the docking block 301a-1 is threadedly connected to a screw rod 303a in the telescopic assembly 303. The other end of the screw rod 303a is fixedly inserted into the connecting plate 302.

[0045] An adjustment handle 303b is fixedly provided on the outer wall of the screw rod 303a. By rotating the adjustment handle 303b, the screw rod 303a can be used to cooperate with the docking block 301a-1 to allow the screw rod 303a to achieve horizontal displacement during the rotation process. After the screw rod 303a moves, the stabilizing triangle plate 301 and the corresponding wire on the right side of the connecting plate 302 can be pulled to the left, so that the distance between the two stabilizing triangle plates 301 is shortened, effectively transferring the force on the insulator.

[0046] A fixing assembly 302a is fixedly provided at the other end of the connecting plate 302, and the fixing assembly 302a is aligned and connected with the mounting hole 301a of the stabilizing triangle plate 301 on the right side, and an insertion bolt 302a-1 is installed through the fixing assembly 302a, and the insertion bolt 302a-1 is aligned with the mounting hole 301a. Through the cooperation of the insertion bolt 302a-1 and the mounting hole 301a, the other end of the connecting plate 302 and the installation of the stabilizing triangle plate 301 can be stabilized.

[0047] One side of the insertion bolt 302a-1 is also fixedly connected to an anti-fall piece 302a-2, which can be a structure such as a steel rope to prevent the insertion bolt 302a-1 from falling due to careless operation after being taken out during aerial operations. A limit lever 302b is elastically rotatably set on one side of the fixed assembly 302a. The limit lever 302b is engaged with the insertion bolt 302a-1 in the default state. The side wall of the insertion bolt 302a-1 is provided with a groove of a corresponding size to cooperate with the limit lever 302b, which can directly block the movement of the insertion bolt 302a-1. When the insertion bolt 302a-1 needs to be pulled out, the insertion bolt 302a-1 can be taken out by pushing away the limit lever 302b.

[0048] 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 preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
