Suspension insulator rotary plug pin device

Abstract

The invention discloses a suspension insulator rotary pin plugging and unplugging device. The device comprises: an insulator correcting device for correcting an insulator sheet; an insulator pin pulling device used for pulling an iron pin in an insulator sheet iron cap; an insulator bolt device used for inserting the iron pin into an insulator iron cap; a transverse moving device used for adjusting the positions of the insulator pin pulling device, the insulator bolt device and the insulator correcting device; and a transverse moving device fixedly arranged on the main fixing base, wherein theinsulator correcting device, the insulator pin pulling device and the insulator bolt device are all fixedly arranged on the transverse moving device. An insulator unloading device, an insulator replacing device and an insulator supporting device are all driven by a driving device, so that the driving device drives a lead screw to rotate and drives all the devices to move front and back to meet the requirement for the freedom degree of all the devices, the insulator replacing operation is achieved, the automation degree is high, operation is easy, and the risk of manual operation is reduced.

Description

technical field [0001] The invention relates to the technical field of electric facility maintenance, in particular to a rotary plugging and pulling out pin device for a suspension insulator. Background technique [0002] The amount of suspension insulator strings in the substation is huge, and the suspension insulator strings are in the open environment for a long time. Under the influence of environmental factors such as wind, sun and sun, the internal stress of the insulators will be unbalanced, resulting in low zero value of the insulators and even structural damage. As a result, the damage defects of suspension insulator strings in substations are increasing day by day. [0003] At present, there is no special replacement tool suitable for the suspension insulator strings in the station. When replacing the suspension insulator strings in the station, it can only be replaced by the traditional method, that is, the hand hoist is used to pull the wires and clamps, so that ...

[0002] The amount of suspension insulator strings in the substation is huge, and the suspension insulator strings are in the open environment for a long time. Under the influence of environmental factors such as wind, sun and sun, the internal stress of the insulators will be unbalanced, resulting in low zero value of the insulators and even structural damage. As a result, the damage defects of the suspension insulator strings in the substation are increasing day by day

[0003] At present, there is no special replacement tool suitable for the suspension insulator strings in the station. When replacing the suspension insulator strings in the station, it can only be replaced by the traditional method, that is, the hand hoist is used to pull the wires and clamps, so that the suspension insulator strings are in the In the non-stressed state, the damaged insulators are disassembled and new insulators are installed. This method requires the cooperation of high-altitude operations and ground operations. Generally, three people are required to cooperate at high altitudes, and two people are required to connect on the ground. Take tools and insulators. This operation method takes a long time and increases the danger of workers working at heights. Moreover, the traction force of the lever hoist is not easy to control, and it is easy to generate overload traction, which will cause damage to the wires or clamps and affect the quality of work.
