[0015] The advantages and positive effects of the present invention are:

[0016] (1), By the maintenance personnel carrying the support plate on their backs, climbing onto the high tower, pulling out the four sliding rods from the corresponding circular tubes, and making the clamps on each sliding rod all carry on the cables in the power transmission and transformation line, and connecting the four clamps to the cables in the power transmission and transformation line, and then locking the sliding rods on the circular tubes, so that the support plate is firmly connected to the cables in the power transmission and transformation line, and then connecting the high-altitude operation safety belt worn on the maintenance personnel to the two pull rings through the lock, and at the same time connecting the high-altitude operation safety belt to the cables in the power transmission and transformation line, so as to ensure that the maintenance personnel are firmly connected to the high tower or the cables in the power transmission and transformation line to prevent high-altitude falling accidents.

[0017] (2) By placing one leg of the maintenance personnel on the front of the support board and the other leg on the back of the support board, the overall center of gravity of the maintenance personnel is more balanced, so that the maintenance personnel can take a short rest on the support board and replenish food and water to restore physical strength. The seat cushion is made of rubber material, which can improve the comfort of the maintenance personnel.

[0018] (3) When the maintenance personnel moves, the support plate moves with them. When the maintenance personnel detects that the cable is in an abnormal state, they can step on the upper surface of the support plate to make the maintenance personnel's body center of gravity more stable. In addition, since the surface of the seat cushion is provided with an anti-slip layer, the friction between the support plate and the sole of the maintenance personnel's shoe can be increased, thereby reducing the possibility of slipping when the maintenance personnel step on the support plate.

[0019] (4) The maintenance personnel sits astride on the support plate, takes out the cable, and places one end of the cable against the cutter. The maintenance personnel then pulls the handle by hand, and the movement of the handle drives the arc rod to move, and the movement of the arc rod drives the cutter to move and compress the elastic member I, so that the cutter moves along the outer surface of the cable in a circle, thereby cutting the insulation layer of the cable. The cable is then pulled to move, so that the insulation layer at the end of the cable falls off, and then the insulation layer at the other end of the cable is stripped off, and the cable is then bridged to the damaged cable, thereby maintaining the cable. The maintenance personnel can also keep the center of their body more balanced when working at high altitudes, and can more conveniently handle new cables, thereby improving the safety of maintenance work and reducing the intensity of maintenance work.

[0020] (5) By manually rotating the threaded rod, the rotation of the threaded rod drives the extrusion block to move toward the guide wheel, so that the extrusion block and the guide wheel jointly press against the cable and compress the elastic part II, thereby clamping and limiting the cable, thereby further reducing the intensity of the maintenance personnel's work, improving the convenience of maintenance work, and making the length of the cable insulation layer stripped more accurate.

[0039] In the prior art, when maintenance personnel perform maintenance work on high-tower power transmission and transformation lines, the maintenance personnel need to use protective devices to ensure that they are firmly connected to the high tower or the cable 3 in the power transmission and transformation line to prevent high-altitude falling accidents. However, the existing protective devices have relatively single functions and lack facilities for maintenance personnel to rest, which causes maintenance personnel to easily feel physically and mentally exhausted during high-intensity operations;

[0040] To solve the above problems, when maintaining the cable 3, first place the tools used for maintenance and several sections of new cables 2 into the storage box 14. Then, the maintenance personnel carry the support plate 1 by two elastic straps 12, and then climb onto the high tower, thereby driving all the connected components to move to the high tower. Moreover, the initial positions of the bracket 203 and all the components connected to the bracket 203 are located below the support plate 1. Therefore, when the maintenance personnel carry the support plate 1, the bracket 203 and all the components connected to the bracket 203 will not affect the maintenance personnel. Then, pull out the four slide rods 202 from the corresponding round tubes 201 in sequence, so that the clamps 2021 on each slide rod 202 are all mounted on the corresponding cable 3 in the power transmission and transformation line. Then, connect the four clamps 2021 to the cable 3 in the power transmission and transformation line in sequence. Then, through the locking member between the round tube 201 and the slide rod 202, lock the slide rod 202 on the round tube 201, so that the support plate 1 is firmly connected to the cable 3 in the power transmission and transformation line. Then, connect the high-altitude work safety belt worn by the maintenance personnel to the two pull rings 13 through a buckle, as Figure 1 shown. At the same time, the maintenance personnel independently connect the high-altitude work safety belt worn on their bodies to the cable 3 in the power transmission and transformation line, so as to ensure that they are firmly connected to the high tower or the cable 3 in the power transmission and transformation line to prevent high-altitude falling accidents.

[0041] When the maintenance personnel feel exhausted after a long period of high-intensity work, they can straddle the support plate 1 with their legs. That is, based on the front part of the support plate 1, one leg of the maintenance personnel straddles the front part of the support plate 1, and the other leg straddles the rear part of the support plate 1, making the overall center of gravity of the maintenance personnel more balanced. Thus, the maintenance personnel can take a short rest on the support plate 1. At the same time, they can replenish food and water to restore physical strength. And the seat cushion 11 is made of rubber material, which can improve the comfort of the maintenance personnel.

[0042] When the maintenance personnel conduct maintenance inspections along the line, they step on the cable 3 connected to the clamp 2021 with their feet, and at the same time hold the other two cables 3 located above the support plate 1 with their hands, and move along the cable 3 to inspect various parts of the cable 3. The maintenance personnel move by pulling the two pull rings 13 through the high-altitude work safety belt and buckle worn on their bodies, thereby driving the support plate 1 to move, and then driving all the connected parts to move. When it is detected that the cable 3 is in an abnormal state locally, the maintenance personnel stops moving at this time, and the maintenance personnel's Both feet can be placed on the upper surface of the support plate 1 to make the maintenance personnel's body center of gravity more stable. Compared with the existing maintenance personnel, when repairing the cable 3, the maintenance personnel need to step on the cable 3 and then inspect the cable 3, which can easily make the maintenance personnel's body center of gravity unstable. This method can greatly increase the stability of the maintenance personnel when repairing the cable 3, and because the surface of the seat cushion 11 is provided with an anti-slip layer, the friction between the support plate 1 and the sole of the maintenance personnel can be increased, thereby reducing the possibility of slipping when the maintenance personnel steps on the support plate 1.

[0043] When cracks or damage appear in the cable 3 in the power transmission and transformation line, maintenance personnel need to manually connect a new cable 2 to the damaged cable 3. In this process, the cable 2 needs to be held manually to keep it stable, and maintenance tools need to be used to handle the new cable 2, which makes the maintenance work very cumbersome and easily causes the center of gravity of the body to shift during the operation, especially for the power transmission and transformation line far away from the high tower, which will seriously affect the safety of the maintenance work. To solve the above problem, when the maintenance personnel connect the cable 2 to the cable 3 in the power transmission and transformation line, the maintenance personnel sit on the support plate 1 in the same way as above, take out the cable 2 stored in the storage box 14, and then pull the bracket 203 so that the bracket 203 is rotated one hundred and eighty degrees counterclockwise along the circular tube 201 with the right side of the support plate 1 as the reference. The rotation of the bracket 203 drives all the connected parts to rotate, so that the arc plate 208 is located above the support plate 1, as shown in FIG. Figure 3As shown in the figure, then the maintenance personnel hold the cable 2 and put one end of the cable 2 into the inner side of the arc-shaped plate 208 and against the cutter 212. Then, the maintenance personnel pull the pull handle 210 by hand. The movement of the pull handle 210 drives the movement of the arc-shaped rod 209. The movement of the arc-shaped rod 209 drives the movement of the cutter 212 and compresses the elastic member I 211. Thus, the cutter 212 moves along the outer surface of the cable 2 for one circle, so as to cut the insulating layer of the cable 2 and divide the insulating layer of the cable 2 into two sections. At this time, the cutter 212 abuts between the two sections of the insulating layer. Then, the maintenance personnel pull the cable 2 to move, so that the insulating layer at the end of the cable 2 falls off. Then, the other end of the cable 2 is put into the inner side of the arc-shaped plate 208 and against the cutter 212, and the insulating layer at the other end of the cable 2 is peeled off, so as to realize the peeling of the insulating layers at both ends of the cable 2. Then, the cable 2 is connected across the damaged cable 3, so as to realize the maintenance of the cable 3. And it can make the center of the maintenance personnel's body more balanced when working at height, make the processing of the new cable 2 more convenient, improve the safety of the maintenance work and reduce the intensity of the maintenance work.

[0044] It should be noted that in order to adapt to cables 2 of different specifications, the pump 214 is controlled to start operating to inflate or suck air into the conduit 215, so that the airbag 213 deforms. The deformation of the airbag 213 drives the deformation of the cutter 212, and then the cutter 212 adapts to cables 2 of different specifications, so as to peel off the insulating layers of cables 2 of different specifications. Embodiment 2

[0045] On the basis of Embodiment 1, according to Figure 4 and Figure 8 As shown in the figure, it further includes a clamping and limiting system; a clamping and limiting system is connected to the bracket 203; the clamping and limiting system includes a support frame 301, a threaded rod 302, an extrusion block 303, a sliding rod 304, a guide wheel 305 and an elastic member II 306; the support frame 301 is fixedly connected to the lower surface of the bracket 203; the threaded rod 302 is rotatably connected to the support frame 301; the end of the threaded rod 302 is rotatably connected to the extrusion block 303; the sliding rod 304 is slidably connected to the support frame 301; the lower part of the sliding rod 304 is rotatably connected to the guide wheel 305; an elastic member II 306 is fixedly connected between the sliding rod 304 and the support frame 301. The elastic member II 306 is a spring. One end of the elastic member II 306 is fixedly connected to the sliding rod 304, and one end of the elastic member II 306 is fixedly connected to the support frame 301.

[0046] The extrusion block 303 is made of rubber material to prevent damage to the cable 2.

[0047] The guide wheel 305 is made of rubber material to increase the friction between the guide wheel 305 and the cable 2.

[0048] When stripping the insulating layer of the new cable 2, in order to further reduce the working intensity of maintenance personnel, improve the convenience of maintenance work, and make the length of the stripped insulating layer of the cable 2 more accurate, the maintenance personnel place the new cable 2 between the extrusion block 303 and the guide wheel 305, and manually rotate the threaded rod 302. The rotation of the threaded rod 302 drives the extrusion block 303 to move towards the guide wheel 305. The movement of the extrusion block 303 drives the cable 2 to move until the cable 2 abuts against the guide wheel 305. The movement of the guide wheel 305 drives the sliding rod 304 to move, thereby stretching the elastic member II 306, so that the extrusion block 303 and the guide wheel 305 jointly abut against the cable 2, thus realizing the clamping and limiting of the cable 2. Then, make the end of the cable 2 abut against the cutter 212, and move the support 205 so that the support 205 moves along the fixed rod 204. Since there are scale lines on the fixed rod 204, the moving distance of the support 205 can be known, so that the lengths of the insulating layers stripped from both ends of the cable 2 are the same. Thus, it is no longer necessary for maintenance personnel to hold the cable 2 during the process of stripping the insulating layer of the cable 2, further reducing the working intensity of maintenance personnel, improving the convenience of maintenance work, and making the length of the stripped insulating layer of the cable 2 more accurate.

Therefore, all equivalent changes made according to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
