Spring pin complement device for live-line operation of power transmission line

Abstract

The invention belongs to the field of power construction appliances and particularly relates to a spring pin complement device for the live-line operation of a power transmission line. The device comprises an insulating telescopic rod (1) and a clamp (5). The device is characterized in that the upper tip of the insulating telescopic rod (1) is fixedly provided with a connecting sleeve (3). The connecting sleeve (3) is respectively fixed with a clamp installation base (4) and a universal shaft seat (8). The universal shaft seat (8) is provided with a tip observation mirror (7). The clamp installation base (4) is fixedly connected with the tail end of one clamp handle of the clamp (5). A compression spring (5-1) is arranged between the two clamp handles of the clamp (5). The tail end of the other clamp handle of the clamp (5) is connected with the upper end of a control pull rope (6) of the clamp (5). The lower end of the control pull rope (6) of the clamp (5) passes through the inner cavity of the insulating telescopic rod (1) to be fixed onto a clamp control rod (10). The clamp control rod (10) is movably arranged in a control rod clamping groove (1-1) of the insulating telescopic rod (1). The spring pin complement device is simple in structure, and solves the problem in the prior art that spring pins are hard to take and supplement. Meanwhile, the spring pin complement device is convenient to take and operate, and the labor intensity of the operating personnel is reduced. The operation efficiency is improved and the live-line working time is reduced.

Description

technical field [0001] The invention belongs to electric power construction equipment, in particular to a spring pin catcher for live working of power transmission lines. Background technique [0002] At present, in the live work of the transmission line, when the insulator bowl head pin is installed and pulled out, the methods used are the equipotential method and the ground potential method. When the ground potential method is used, the operator uses the insulating operating rod and the The pin-removing pliers installed at the front end of the rod are used for operation. During the operation, the jaws of the pin-removing pliers are not easy to align with the bottom opening of the spring pin. The jaws of the pin-removing pliers are clamped by the operator rotating the insulating operating rod. During the process, it is easy to make the position of the jaws of the pin removal pliers shift, and the rotation of the pin removal pliers is not very flexible, which increases the o...

[0002] At present, in the live work of the transmission line, when the insulator bowl head pin is installed and pulled out, the methods used are the equipotential method and the ground potential method. When the ground potential method is used, the operator uses the insulating operating rod and the The pin-removing pliers installed at the front end of the rod are used for operation. During the operation, the jaws of the pin-removing pliers are not easy to align with the bottom opening of the spring pin. The jaws of the pin-removing pliers are clamped by the operator rotating the insulating operating rod. During the process, it is easy to shift the position of the jaws of the pin-removing pliers, and the rotation of the pin-removing pliers is not very flexible, which increases the difficulty of operation for the operator, prolongs the working time, and increases the labor intensity.
