Problems solved by technology

At present, the operator usually hangs the fixed pulley under the insulator string, and the suspension rope goes around the fixed pulley. The ground operator connects one end of the suspension rope to the insulator, and the other end exerts a pulling force to make the insulator rise to the bottom of the insulator string. You need to rely on your own strength to lift the insulator to the top of the insulator string under the condition of no force point, and then install the insulator with the installation tool. There are risks when lifting the insulator when working at heights. If you are not careful, it is easy to cause the insulator to fall. The insulator is in the process of lifting. Medium, the sling is easy to knot and entangle, and the use stability is poor
This brings great inconvenience to the replacement of insulators

Description

Technical field [0001] The invention relates to the technical field of insulator replacement, and in particular to an auxiliary device for replacing a power transmission tensile insulator and a use method thereof. Background technique [0002] In the high-voltage power system, the insulator is a common component, and the insulator needs to be replaced when it is damaged. The replacement of the insulator is a high-altitude operation. It is necessary to use a device to transfer the insulator on the ground to the insulator string at a high place, and then remove the damaged insulator Disassemble it and install a new insulator. At present, the operators usually hang the fixed pulley under the insulator string, and the lifting rope bypasses the fixed pulley. The ground operator connects one end of the lifting rope to the insulator, and the other end applies pulling force to make the insulator rise below the insulator string. You need to rely on your own strength to lift the insulator...
