Problems solved by technology

[0004] Existing tools for replacing insulators, if the opening direction of the insulator pins is vertical to the line direction, it is difficult for the existing tools to complete this kind of work. The pins were pulled out during the operation, but the pins fell off and objects fell from high altitude, which increased the risk of operation

Abstract

The invention provides a straight vertical pin clamp which comprises a pin pull clamp and an operating rod which is connected to the pin pull clamp. The rod body working section of the operating rod is provided with a thread, a rotary connecting head is rotated on the working section, the two sides of the rotary connecting head is radially and symmetrically provided with one end of a two-connection rod A and one end of a two-connection rod B in a hinge way. A threaded push head is fixed at the front end of the operating head. The other end of the two-connection rod A and the other end of the two-connection rod B are symmetrically hinged to at two radial sides of the threaded push head. A handle connection piece is fixed at two tail ends of the handle of the pin pull clamp. The middle pivot point of the two-connection rod A and the middle pivot point of the two-connection rod B are hinged to the handle connection piece. The straight vertical pin clamp has the advantages that the operation of live replacement of an insulation is feasible when an insulator pin opening direction is a vertical line, the whole operation is convenient, the risk of object falling from a high altitude is effectively reduced, and the risk of such operations is reduced.

Description

technical field [0001] The invention belongs to the field of power equipment maintenance, and particularly relates to the pin removal work when replacing a linear insulator string with electricity when the opening of the insulator pin of a transmission line of 110kV and above is placed in a direction perpendicular to the line. Background technique [0002] The insulator is a special insulation control. The insulator plays two basic functions in the overhead transmission line, that is, supporting the wire and preventing the current from returning to the ground. These two functions must be guaranteed. The insulator should not change due to environmental and electrical load conditions. Otherwise, the insulator will not have a significant effect, and it will damage the service life and operating life of the entire line. During the operation of the transmission line, due to external damage, lightning, pollution flashover and other reasons, the insulator self-exploded or lost its ...
