Problems solved by technology

However, when this pin remover removes the pin, the engaging part is used as the point of application of force, and the operating rod needs to be rotated and pushed so that the pin removing post of the jaws can remove the R-type pin, which is inconvenient to operate and consumes more physical strength of the operator. The pin remover cannot be used to install R-type pins, nor can it be turned to adjust, which is inconvenient for special work stations, thus affecting work efficiency

Description

technical field [0001] The invention relates to the technical field of disassembly and assembly of insulators, in particular to an insulator string R-shaped pin ground potential diversion device and method. Background technique [0002] At present, the lower end of the insulator strings of 220kV overhead transmission lines is locked with R-type pins. When sampling or replacing the insulator strings, only power outage or equipotential operation can be used for disassembly and assembly. However, power outage operations have large economic losses and are not easy to apply for. The type and wire arrangement limit the operation efficiency and low. [0003] The patent document with the notification number CN 207010080 U discloses an improved synthetic insulator R-type pin remover, which belongs to the technical field of mechanical equipment maintenance and disassembly. The tail of the body is provided with a handle, and the front end of the body is provided with a hook head, whic...
