Overhead ground wire lifting device

Abstract

The invention belongs to the field of electric power device maintenance and specifically relates to an overhead ground wire lifting device. A ground wire cross-arm clamping tool groove is clamped on one side of a ground wire cross-arm, a ground wire cross-arm fixed clamping tool is fixed on the ground wire cross-arm via a first clamping tool fixing screw bolt and a second clamping tool fixing screw bolt, and a ground wire hook is welded and fixed on a lower end head of a lifting lead screw; a part, positioned above the ground wire hook, of a lower end of the lifting lead screw is connected with one end of a handle via a ratchet mechanism arranged on a left end part of handle; an upper end of the lifting lead screw is connected with a lifting lead screw nut in a threaded manner after running through a lead screw fixing hole positioned on a side, opposite to the ground wire cross-arm clamping tool groove, of the ground wire cross-arm fixed clamping tool; the lifting lead screw nut is welded and fixed above the lead screw fixing hole. The fixed clamping tool made of novel material is employed in the overhead ground wire lifting device, the fixed clamping tool is fixed on iron tower ground wire cross-arm tower material, the lead screw fixed on the clamping tool is used for lifting or dropping an overhead ground wire, and an aim of checking, repairing or changing the ground wire can be attained. Operation time is shortened, and overhaul efficiency is improved.

Description

technical field [0001] The invention belongs to the field of electric equipment maintenance, in particular to an overhead ground wire lifting device. Background technique [0002] There are no special tools or devices for lifting overhead ground wires in the field of transmission line inspection. All units use non-professional tools such as pulleys, hand hoists, wire rope sets, and walkers to carry out operations. There are many shortcomings, such as cumbersome operations. Construction experience; there are large risk factors that endanger the personal safety of operators; it takes a long time and the workload is heavy; there are many tools, the total weight of the tools is large, and the operation is complicated. Now it is necessary to develop a special tool with strong versatility, lightness and durability, simple operation, safety and reliability, so as to reduce labor intensity, improve work efficiency and safety and reliability. [0003] In order to solve these problem...
