[0002] Insulators are an important component used in electrical equipment and transmission lines. They are mainly made of insulating materials and are used to support and fix conductors. At the same time, they ensure that the conductors maintain a sufficient electrical insulation distance from the ground or other structures to prevent current from leaking to the ground or other non-conductive parts. Insulators play a vital role in the power system. They can withstand mechanical loads, environmental impacts, and electrical loads. When the power grid is laying cables, insulators are installed between the cables and the tension towers to ensure reliable insulation between the tension towers and the cables. Insulators need to be replaced after long-term use or damage to ensure reliable insulation between the cables and the tension towers. Insulator replacement tools refer to special tools used to replace or maintain insulators in transmission lines. Tools and equipment. These tools and equipment are designed to complete the replacement of insulators safely and efficiently, reduce power outage time and improve work efficiency. When replacing insulators, the cables on the insulators are first removed, and then the insulator replacement operation is performed. Since the cable is heavy, the cable needs to be fixed on the cross arm of the tension tower after it is removed. In the prior art, after the cable is removed from the insulator, a rod set on the cross arm is used to fix the cable.

By setting a fixing rod, the support rod can be conveniently set on the cross arm of the tension tower, thereby improving the fixing efficiency and fixing strength of the support rod. By using a hand winch and a rope to tighten the cable, the cable is convenient to tighten and the labor intensity of the operator is reduced. By setting a fixing line and a positioning line, the support rod is more firmly fixed, thereby improving the safety performance during the insulator replacement process. However, the document requires 2-3 people to cooperate in the operation, which has high labor intensity and low efficiency. In addition, the operation process is relatively complicated, and it is not simple and convenient to use. Summary of the invention

[0038] The wire-taking mechanism comprises a wire-taking roller 8, a connecting block 9, a fixing block 10 and a fixing bolt 11. The outer surface of the wire-taking roller 8 is fixedly connected to the connecting block 9, the upper surface of the connecting block 9 is fixedly connected to the fixing block 10, and the inner wall of the fixing block 10 is threadedly connected to the fixing bolt 11.

[0039] The fixed pulley block includes a positioning frame 12, a hanging ring 13, a hook 14, a pulley frame 15, and an insulating pulley body 16. The lower surface of the positioning frame 12 is fixedly connected to the hanging ring 13, the hook 14 is hung below the hanging ring 13, the pulley frame 15 is serially connected below the hook 14, and the insulating pulley body 16 is arranged below the pulley frame 15 through a rotating shaft.

[0040] The core part of the tool is the gear box 2, which not only has the storage function of a traditional tool box, but also has components such as a take-up roller 8 and a connecting block 9 installed inside. The gears on the back of the turntable 5 have a strict transmission relationship with these internal structures, and its flexibility can adapt to different working environments and the use of tools of different sizes. When the turntable is controlled by the handle 6, the wire rod 23 set on the box body is used to guide the wire to be wound onto the take-up roller 8, so that the automatic take-up function of the take-up roller 8 can be realized, which greatly improves work efficiency.

[0041] As another important part of this tool, the fixed pulley block includes a positioning frame 12, a hanging ring 13, a hook 14, a pulley frame 15, and an insulating pulley body 16. The lower surface of the positioning frame 12 is fixedly connected with the hanging ring 13, the hook 14 is hung below the hanging ring 13, the pulley frame 15 is connected in series below the hook 14, and an insulating pulley body 16 is arranged below the pulley frame 15 through a rotating shaft.

The two pins 21 are symmetrically arranged, which helps to maintain the balance and stability of the fixing plate 18.

[0054] The working principle of the new insulator replacement tool provided by the present invention is that when using the new insulator replacement tool, the operator first firmly installs the gear box in a suitable position through the positioning block 4 and the positioning hole on the base 1, then fixes the rope to be used on the take-up roller 8 and the conductor rod 23, and fixes it through the positioning bolt 11, then fixes the positioning frame 12 on the cross arm near the replacement insulator through the fixing plate 18, uses the fixing pin 21 and the fixing nut 22 to fix the fixing plate 18, thereby fixing the position of the rope, passes the rope through the insulating pulley body 16, then the operator holds the rotating sleeve 7, rotates the handle 6 to drive the turntable 5 to rotate, thereby driving the take-up roller 8 and the conductor rod 23 to rotate to realize the rope retraction and release, and finally performs the insulator replacement operation. The movable pulley group can be used to hoist the replaced old insulator and the new insulator to be installed. The whole process saves time and effort and can be completed quickly.
