Therefore, it is necessary to temporarily install a pulley on the high-voltage wire tower to change the traction direction of the high-voltage test leads.

[0048] In an optional embodiment, the lead wire adjustment assembly 3 further includes a reinforcing plate 36 , and an outer side of one end of the reinforcing plate 36 is fixedly connected to the outer side of the bottom end of the movable bracket 31 .

[0049] In this embodiment: in the process of high-voltage testing of electrical equipment, it is necessary to set up high-voltage wires, and the high-voltage wires are fixed on the high-voltage wire tower through the insulating wire 1. In this process, the insulating wire 1 is generally pulled by the high-voltage test lead 313 to raise it, so that the insulating wire 1 is moved to the position of the lifting ring 2, and the traction device of the high-voltage test lead 313 is generally set on the ground. Therefore, it is necessary to temporarily install a pulley on the high-voltage wire tower, and change the traction direction of the high-voltage test lead 313 by the pulley. However, the pulley can only be temporarily installed at a position close to the lifting ring 2, and the pulley cannot be installed at a position that just overlaps with the lifting ring 2, otherwise the high-voltage test lead 313 will be affected by the lifting ring 2 and cannot be pulled. The close distance between the pulley and the lifting ring 2 also means that the insulating wire 1 cannot directly contact the lifting ring 2 through the traction of the high-voltage test lead 313, which makes the installation of the insulating wire 1 more troublesome;

[0050] By setting the lead adjusting assembly 3, the lead adjusting assembly 3 can be installed at a position close to the lifting ring 2. When the high-voltage test lead is pulled by the lead adjusting assembly 3 to rise to a position close to the lifting ring 2, the position of the high-voltage test lead 313 can be further changed by changing the angle of the lead adjusting assembly 3 itself, thereby further changing the position of the insulating wire 1, and realizing fine adjustment of the position of the insulating wire 1. After the position of the insulating wire 1 is finely adjusted, it can contact the lifting ring 2, thereby making it easier to fix the insulating wire 1 and the lifting ring 2;

[0051] First, it is necessary to temporarily install the lead adjustment assembly 3 on the high-voltage power line tower. Specifically, it is temporarily hung on the high-voltage power line tower through the metal hook 3151 so that the lead adjustment assembly 3 is close to the lifting ring 2. The lifting ring 2 is fixed on the high-voltage power line tower in advance. The high-voltage test lead 313 is rotatably connected to the first U-shaped wheel 311 and the second U-shaped wheel 312 at the same time, and then the two ends of the high-voltage test lead 313 are allowed to hang freely, one end of the high-voltage test lead 313 is fixedly connected to the insulating wire 1, and the other end of the high-voltage test lead 313 is fixedly connected to the traction device. The high-voltage test lead 313 is pulled by the traction device to make one end of the high-voltage test lead 313 move downward, and the first U-shaped wheel 311 and the second U-shaped wheel 312 are connected. After the second U-shaped wheel 312 turns, the other end of the high-voltage test lead 313 will move upward, thereby driving the insulated wire 1 to move upward, and the bottom end of the insulated wire 1 is connected to the high-voltage wire, thereby driving the high-voltage wire to move upward together. It should be noted that in this state, when the insulated wire 1 is lifted upward, the positions of the first U-shaped wheel 311 and the second U-shaped wheel 312 are not on the same horizontal plane, but are set one high and one low. The position of the first U-shaped wheel 311 should be lower than the position of the second U-shaped wheel 312, which can be achieved by tilting the movable bracket 31. Specifically, the position of the hook assembly 315 and the bar groove 314 in the movable bracket 31 can be adjusted to change the tilt angle of the movable bracket 31.

[0052] Embodiment 1: When the insulated wire 1 is pulled by the high-voltage test lead 313 to the vicinity of the lifting ring 2, since the projections of the insulated wire 1 and the lifting ring 2 on the ground are not at the same position at this time, that is, the insulated wire 1 and the lifting ring 2 are not on the same vertical line, firstly, the movable bracket 31 is rotated through the rotating connecting member 32, so that the plane formed by the axis connection extension line of the first U-shaped wheel 311 and the second U-shaped wheel 312 rotating around the axis of the first U-shaped wheel 311 or the second U-shaped wheel 312 can coincide with the lifting ring 2, and then the movable bracket 31 is adjusted. The movable bracket 31 is positioned with respect to the horizontal axis 3153 so that the movable bracket 31 can rotate around the horizontal axis 3153 to adjust the angle. In this step, the upper rotating body 321 and the lower rotating body 322 can be relatively rotated. The steel ball 323 can be provided to reduce the rotation resistance between the upper rotating body 321 and the lower rotating body 322. By rotating the first rotating shaft 333, the rotation of the first rotating shaft 333 will drive the threaded rod 332 to rotate. The rotation of the threaded rod 332 will drive the limit slide bar 331 to move. The movement of the bar 331 will drive the sliding block 33 to move, and the movement of the sliding block 33 will drive the horizontal axis 3153 to move. The horizontal axis 3153 is the suspension center of the movable bracket 31. When the position of the horizontal axis 3153 relative to the movable bracket 31 changes, the inclination angle of the movable bracket 31 will also change. Since the position of the horizontal axis 3153 relative to the high-voltage power tower is fixed, when the inclination angle of the movable bracket 31 changes, the movable bracket 31 will drive the first U-shaped wheel 311 and the lifting ring 2 to change. Moreover, since the positions of the horizontal axis 3153 relative to the lifting ring 2 and the high-voltage power tower are both fixed, when the relative position of the horizontal axis 3153 and the movable bracket 31 changes, it will also directly cause the position of the movable bracket 31 relative to the lifting ring 2 to change. Therefore, it is easier to adjust the position of the first U-shaped wheel 311 and the lifting ring 2. It should be understood that there are two ways to adjust the position of the first U-shaped wheel 311 from the lifting ring 2, one is to adjust the inclination angle of the movable bracket 31, and the other is to adjust the position of the movable bracket 31.

[0053] When the movable bracket 31 drives the first U-shaped wheel 311 to move to the target position, the first U-shaped wheel 311 will drive the high-voltage test lead 313 to drive the top suspension hole of the insulating wire 1 to match the position of the lifting ring 2. At this time, the insulating wire 1 can be fixedly connected to the lifting ring 2, thereby realizing the installation of the insulating wire 1;

[0054] When adjusting the angle of the movable bracket 31, it can be achieved by adjusting the position of the horizontal axis 3153 relative to the movable bracket 31. When the horizontal axis 3153 is located at the central position of the movable bracket 31, the movable bracket 31 is more inclined to be set in a horizontal state, that is, the first U-shaped wheel 311 and the second U-shaped wheel 312 are basically at the same height, so that the angle of the movable bracket 31 can be adjusted. It should be understood that by adjusting the position of the horizontal axis 3153 on the movable bracket 31, the angle of the movable bracket 31 can be adjusted, and at this time, it does not affect the continued pulling of the high-voltage test lead 313, so that while adjusting the position of the movable bracket 31, it also has the function of adjusting the height of the insulated wire 1;

[0055] Embodiment 2: When the position of the horizontal axis 3153 relative to the movable bracket 31 is not adjusted, the angle of the movable bracket 31 can still be adjusted. The sliding rod 351 is moved to make the sliding rod 351 slide inside the fixed block 35, so that the sliding rod 351 moves to drive the rotating rod 353, thereby driving the clamping rod 355 to move to the vicinity of the second U-shaped wheel 312. Then, the rotating rod 353 is moved to make the rotating rod 353 move along the axial direction of the rotating rod 353. The rotating rod 353 will drive the clamping rod 355 to insert into the clamping groove 356 provided on the second U-shaped wheel 312, thereby limiting the rotation of the second U-shaped wheel 312. At this time, the high-voltage test lead 313 continues to be pulled. Since the high-voltage test lead 313 will not drive the first U-shaped wheel 311 and The second U-shaped wheel 312 rotates, so the high-voltage test lead 313 is stationary relative to the second U-shaped wheel 312 at this time. Under the continued traction of the high-voltage test lead 313, the high-voltage test lead 313 will drive the second U-shaped wheel 312 and thus drive the movable bracket 31 to rotate around the horizontal axis 3153. At this time, no matter where the horizontal axis 3153 is in the strip groove 314, the angle adjustment of the movable bracket 31 can be achieved. The advantage of this adjustment method is that when adjusting the angle of the movable bracket 31, it is not affected by the position of the movable bracket 31 relative to the horizontal axis 3153. Therefore, this adjustment method has better controllability. The method of use in Example 1 is more flexible in adjusting the angle of the movable bracket 31, but the controllability is slightly worse.

[0056] There are two ways to drive the first rotating shaft 333 in the first embodiment. The first way is as follows: by moving the rotating rod 353, the rotating rod 353 moves relative to the sliding rod 351, so that the rotating rod 353 moves and drives the clamping rod 355 to separate from the clamping groove 356. At this time, the worker holds the rotating rod 353 and rotates it, so that the rotating rod 353 drives the sliding rod 351 and drives the fixed block 35 to rotate around the second rotating shaft 341. The rotation of the second rotating shaft 341 drives the flexible shaft 34 to rotate, and the rotation of the flexible shaft 34 drives the first rotating shaft 333 to rotate.

[0057] The second method is as follows: first, the locking rod 355 cannot be engaged with the locking groove 356, and then the worker holds the manual rod 345 to move the manual rod 345 to drive the rotating bracket 342 to rotate around the rotating base 343. The rotation of the rotating bracket 342 will drive the small U-shaped wheel 344 to contact the high-voltage test lead 313. When the high-voltage test lead 313 is pulled and moved, the high-voltage test lead 313 will drive the small U-shaped wheel 344 to rotate. The rotation of the small U-shaped wheel 344 will drive the second rotating shaft 341 to rotate. The rotation of the second rotating shaft 341 will drive the flexible shaft 34 to rotate. The rotation of the flexible shaft 34 will drive the first rotating shaft 333 to rotate.

[0058] The structural strength of the movable bracket 31 can be increased by providing the reinforcing plate 36 .

[0059] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
