[0002] Insulators are important insulating support components of power grids. Insulators are suspended on high-voltage transmission lines to ensure the safe operation of the power system. Insulator deterioration poses a serious threat to the safe and stable operation of the power system. Therefore, when an insulator fails, it needs to be replaced. In order to facilitate the replacement of insulators in the suspended state, auxiliary replacement devices are needed to clamp and fix them.

[0003] However, the currently used insulator auxiliary replacement device, after clamping and fixing the insulator near the replacement insulator and then disassembling the replacement insulator, does not make it convenient to adjust the spacing of the auxiliary replacement device by freeing up both hands. It is also inconvenient for a single person to use the auxiliary replacement device to flexibly disassemble and assemble the insulator. Therefore, we propose a hoisting insulator auxiliary replacement device to solve the above-mentioned problems. Utility Model Content

The second lead screw is threadedly connected to the movable frame. A sliding rod is connected to the bottom of the base at the front position. A second connecting rod is connected to the opposite side of the movable frame. A second support rod passes through the inside of the second connecting rod. A second positioning plate is installed in the middle of the second support rod.

[0009] Preferably, the first connecting rod is slidably connected to the first support rod, and the length of the first support rod is greater than the total length of the first connecting rod.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-6 The present invention provides the following technical solution: an auxiliary replacement device for hoisting insulators, comprising a base 1, a rotating shaft 2 rotatably connected to the right end of the base 1, a fixed seat 3 connected to the outer side of the rotating shaft 2, and limit frames 4 installed on both the front and rear sides of the fixed seat 3; a first connecting rod 5 is installed on the right end of the base 1, a first support rod 6 passes through the inside of the first connecting rod 5, a fixed column 7 is connected to the upper end of the first support rod 6, a spring 10 is connected inside the fixed column 7, a movable column 8 is connected to the end of the spring 10, and a first positioning plate 9 is installed at the end of the movable column 8;

[0026] Furthermore, the first connecting rod 5 is slidably connected to the first support rod 6, and the length of the first support rod 6 is greater than the total length of the first connecting rod 5, which facilitates the installation of the first lead screw 11 and the fixing column 7 on the first support rod 6, and will not obstruct the movement of the first connecting rod 5;

[0027] The right side of the first support rod 6 is rotatably connected to the first lead screw 11, the outer side of the first lead screw 11 is threaded to the moving plate 12, the end of the moving plate 12 is hinged to the adjusting rod 13, and the end of the adjusting rod 13 is hinged to the first connecting rod 5.

[0028] Furthermore, the adjusting rod 13 is inclined and is movably disposed between the moving plate 12 and the first connecting rod 5. The movement of the moving plate 12 drives the adjusting rod 13 to rotate and pushes the first connecting rod 5 to move.

[0029] A movable frame 14 is fitted on the left end of the base 1. A second lead screw 15 is rotatably connected to the bottom of the base 1 at the rear position. The second lead screw 15 is threadedly connected to the movable frame 14. A sliding rod 19 is connected to the bottom of the base 1 at the front position. A second connecting rod 16 is connected to the opposite side of the movable frame 14. A second support rod 17 passes through the inside of the second connecting rod 16. A second positioning plate 18 is installed in the middle of the second support rod 17.

[0030] Furthermore, the positions of the first positioning plate 9 and the second positioning plate 18 are respectively set to correspond to each other, and the outer corners of the first positioning plate 9 and the second positioning plate 18 are both smooth arc-shaped to avoid the first positioning plate 9 and the second positioning plate 18 scratching the insulator.

[0031] Furthermore, the movable frame 14 has a "U" shaped structure, and the upper end of the movable frame 14 is adapted to the limiting frame 4. The movable frame 14 and the limiting frame 4 form a sliding structure, which can be used to limit the fixed seat 3, so that the fixed seat 3 and the base 1 are fixed on the insulator.

[0032] Furthermore, the movable frame 14 is slidably connected to the slide rod 19, and the slide rod 19 and the second lead screw 15 are distributed parallel to each other, which can support the movable frame 14 and make the movable frame 14 move stably.

[0033] Specifically, when using this insulator replacement auxiliary device, align the first positioning plate 9 with the insulator skirt to be removed, and align the base 1 with the end of the adjacent insulator. Push upwards from below, causing the base 1 to engage with the end of the adjacent insulator. The first positioning plate 9, pressed by the insulator skirt, moves towards the fixed post 7. The moving post 8 slides within the fixed post 7, stretching and storing force in the spring 10 until the first positioning plate 9 engages with one side of the insulator skirt. Then, rotate the fixed base 3, causing it to rotate via the rotating shaft 2, closing the fixed base 3 and the base 1 together. Rotate the second lead screw 15, causing the second lead screw to engage with the insulator skirt. Rod 15 drives the outer threaded movable frame 14 to move to the right. Another movable frame 14 slides on the slide rod 19, so that the upper end of the movable frame 14 moves into the limiting frame 4, locking the enclosed fixed seat 3 and base 1, thereby fixing the entire device on the insulator. Continue to rotate the second screw 15, so that the movable frame 14 continues to move to the right, thereby controlling the second connecting rod 16 and the second support rod 17 to move to the right, and then controlling the second positioning plate 18 to move to the right until the second positioning plate 18 is in contact with the other side of the insulator skirt. The second positioning plate 18 and the first positioning plate 9 are used to support the insulator that needs to be replaced, so that the workers can disassemble the insulator.

[0034] Rotating the first lead screw 11 causes the threaded movable plate 12 to move to the left. The movable plate 12 causes the end-hinged adjusting rod 13 to rotate. The adjusting rod 13 pushes the end-hinged first connecting rod 5 to move away from each other, thereby increasing the gap between the insulator to be replaced and the adjacent insulator. Then, holding the insulator with one hand and rotating the second lead screw 15 in the opposite direction with the other hand, the movable frame 14 can be controlled to move to the left, thereby controlling the second positioning plate 18 to move to the left by one distance. At this time, the left end of the movable frame 14 is still within the limiting frame 4. The support for the insulator is released, and the insulator can be removed. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
