With the continuous development of society, especially the emergence of electricity, the progress of society has entered a period of rapid development, and people's dependence on electricity is becoming stronger and stronger, and ensuring the normal supply of electricity has become a very important task .

In electric power work, live work is the non-stop work on high-voltage live lines and equipment. The implementation of live work can reduce the time of power failure, improve the reliability of power supply, and improve the quality of power supply service. Therefore, live work has become an indispensable means of operation in power distribution maintenance and emergency repair.

Live work methods can be divided into three types: equipotential work, intermediate potential work, and ground potential work according to the different potentials of the human body. Among them, according to the different voltage levels and protection points, two working forms of intermediate potential and ground potential are used in live distribution work.

At present, the intermediate potential mainly adopts the operation method of using an insulating bucket truck or an insulating platform. Due to the limitations of vehicle cost, size, applicable conditions, etc., the scope and environment of the intermediate potential operation method are relatively high, which is not conducive to the further promotion of live work. The ground potential operation method is to adopt the foot buckle to climb the pole and utilize the insulating pole operation mode. It has the characteristics of simple operation, less restrictive conditions and wide application range. Therefore, the promotion of ground potential work method will become the development direction of live work in the future.

The cross-arm in the distribution line mainly adopts two forms of single cross-arm and double cross-arm device. And most of the ground potential electrified start-up work is carried out on the double cross-arm electric pole; 3 Double crossarm 1 near the top. Insulated pulleys are often used to cooperate with insulated circulating ropes or single ropes to lift conductors, transfer tool materials, etc.

However, the conventional pulley needs to be installed on the cross arm, so when installing and removing the cross arm, the operator will climb the pole to a higher height, which will reduce the safety distance between the operator and the electrified body and the grounding body, making it difficult to ensure the safety of the operation. Reduced work efficiency.

Therefore, it is already a problem worth studying to provide an auxiliary device that can use the existing cross-arm device in the power distribution line to perform auxiliary operations and greatly improve the safety and efficiency of the operation.

In order to overcome the deficiencies in the above-mentioned prior art, the utility model provides a convenient and reliable device, which can effectively ensure the safe distance between the operator and the charged body and the grounded body, and effectively improve the operating efficiency of the live wire and the transfer tool. The special loop rope frame device for ground potential.

The purpose of this utility model is achieved in that:

The special circulating rope frame device for live work in power distribution includes a support rod 4, and the middle part of the support rod 4 fixes the top of the insulating rod 7 with the support rod 4 through the fastening bolt group b of the insulating bolt rod; the insulating rod 7 is close to A pulley 5 is fixed below the support rod 4 through the pulley fastening bolt group c, and a combined circulating rope is worn on the pulley 5;

The combined loop rope includes an insulating single rope 6 and an insulating loop rope 8;

The support rod 4 has a T-shaped structure, and horizontally downward hooks 9 are arranged at both ends of the horizontal direction; the support rod 4 is used as two rods side by side, and the bolt group a and insulating bolts are fastened by the support rod The rod fastening bolt group b and the pulley fastening bolt group c are fixed;

The fastening bolts in the pulley fastening bolt group c pass through the insulating rod 7 and the side-by-side support rods 4 in sequence, and the pulley 5 is arranged in the middle of the side-by-side support rods 4, and penetrates inside the pulley fastening bolt group c fastening bolts.

Positive and beneficial effects: the utility model has simple structure, convenient and reliable operation, can effectively ensure the safe distance between the operator and the electrified body and the grounding body, and at the same time effectively improve the operating efficiency of the electrified line and the transfer of tools.

detailed description

Below in conjunction with accompanying drawing, the utility model is described further:

As shown in Figure 2, the special circulating rope rack device for live work in power distribution includes a support rod 4, and the middle part of the support rod 4 fixes the top of the insulation rod 7 with the support rod 4 through the fastening bolt group b of the insulating bolt rod; The insulating rod 7 mentioned above is fixed with a pulley 5 through the pulley fastening bolt group c near the support rod 4 below, and the pulley 5 is worn with a combined loop rope;

The combined loop rope includes a single rope 6 and a loop rope 8;

As shown in Figure 3 and Figure 4, the support rod 4 has a T-shaped structure, and horizontally downward hooks 9 are provided at both ends of the horizontal direction;

The support rods 4 are used side by side, and are fixed by the support rod fastening bolt group a, the insulating bolt rod fastening bolt group b and the pulley fastening bolt group c;
