The present invention can reach through following measures:

A high-voltage power line grounding wire operating rod, including a telescopic electroscope insulating rod, an external locking device is provided at the telescopic joint of the insulating rod, and a handle is provided at the rear end of the outermost insulating rod. A Y-shaped bracket composed of two pulley poles, the connecting rod on the bracket is connected with the front end of the innermost insulating rod through threads, and the pulley poles on the bracket are respectively provided with pulleys.

One end of the pole described in the utility model is provided with an external thread, and the other end is connected with one end of the two pulley poles. The other ends of the pulley poles are respectively provided with a U-shaped pulley bracket, and the pulley is installed on the U-shaped pulley bracket through the pulley shaft. Above, the angle between the two pulley poles is 15o-60o, and a support pole can be set between the two U-shaped pulley brackets to improve the connection strength and ensure its stable operation.

When the utility model is in use, adjust the length of the insulating rod according to the position where the grounding wire needs to be hung, then fix and lock it with an external locking device, connect the grounding wire with the insulating rope, and then introduce one end of the insulating rope into two pulleys, and pull it with one hand. Tighten the insulating rope, and control the operating rod with one hand to extend to the wire head where the grounding wire needs to be hung. The frame is connected and fixed. The electroscope operating rod in the utility model is made of high-quality polyoxymethylene material with good insulation and mechanical properties, light weight, and moisture-proof treatment. The operating rod nodes are expanded and connected, and an external locking device is added. , The connection is convenient and reliable; the fixed pulley block is made of engineering plastics, which is strong and light, ensuring the safety of the use process. It has the advantages of simple operation, time-saving and labor-saving, safe use, and accurate grounding wire hanging position.

detailed description

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

As shown in the figure: a high-voltage power line grounding wire operating rod, including a telescopic electroscope insulating rod 1, an outer locking device 2 is provided at the telescopic joint of the insulating rod 1, and a handle is provided at the rear end of the outermost insulating rod. The structure of each component and the interconnection relationship between them are the same as the prior art, and this will not be repeated. The utility model is characterized in that it is provided with a Y-shaped support composed of a connecting rod 3 and two pulley poles 4 and 5. The support The connecting rod 3 on the top is connected with the front end of the innermost insulating rod through threads, and the pulley rods 4 and 5 on the bracket are respectively provided with pulleys 6 and 7, and one end of the rod 3 is provided with external threads to connect with the insulating rod The front ends are connected, and the other end of the pole 3 is connected with one end of the two pulley poles 4, 5. The other ends of the pulley poles 4, 5 are respectively provided with U-shaped pulley brackets, and the pulleys 6, 7 are installed on the On the U-shaped pulley bracket, the angle between the two pulley poles is 15o-60o, and a support rod 10 can be provided between the two U-shaped pulley brackets to improve the connection strength and ensure its stable operation.
