Duplex insulator string hoisting tool

Abstract

The invention provides a duplex insulator string hoisting tool, and relates to the technical field of power construction equipment. The duplex insulator string hoisting tool comprises a cross beam andlocking parts, a hoisting part is arranged in the middle of the cross beam and is used for being connected with a rope. The two locking parts are arranged at the two ends of the cross beam and used for being locked with end fittings of composite insulator strings. Each locking part comprises a first locking body and a second locking body, the first side of each first locking body is connected with the cross beam, and a first arc-shaped groove is formed in the opposite second side of each first locking body. A second arc-shaped groove is formed in the first side of each second locking body, and the first locking body is detachably connected with the corresponding second locking body. The first side of each second locking body is buckled on the second side of the corresponding first lockingbody, and the first arc-shaped grooves and the second arc-shaped grooves form locking through holes for containing and locking the end fittings. The duplex insulator string hoisting tool is used forhoisting the duplex insulator strings, friction and collisions between the two duplex insulator strings can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of electric power construction equipment, in particular to a double insulator string lifting tool. Background technique [0002] An insulator string refers to an assembly of two or more insulator elements combined to flexibly suspend conductors. At the same time, the insulator string has protective devices required for fixing and operation, which are used to suspend the wires and insulate the wires from the tower and the earth. Therefore, the insulator string is the most common product for today's transmission line wiring. [0003] In the prior art, double insulator strings have been invented in order to meet the tension or insulation performance, and have been widely used in ultra-high voltage and ultra-high voltage transmission lines. Among them, the double insulator string is connected by the lower ends of two composite insulator strings through the connecting plate. The connecting plate is a whole. Th...
