Live working wire lifter

Abstract

The invention discloses a live working wire lifter, and belongs to a lifting device. The live working wire lifter structurally comprises two hoops and two sets of lifters, wherein the two hoops are an upper hoop body and a lower hoop body respectively; the upper hoop body and the lower hoop body are fixed to a pole through fixed bolts separately; each set of lifter comprises an upper insulating support rod, a lower insulating support rod, a connection device, a guide wheel, a lifting wheel, a lifting hook and an insulating lifting rope; each upper insulating support rod is suspended on the fixed bolt on the upper hoop body through an upper hook body and is connected with the upper hoop body; and each lower insulating support rod is suspended on the fixed bolt on the lower hoop body through a lower hook body and is connected with the lower hoop body. The live working wire lifter has the characteristics that the structure is relatively light; quick lifting of a wire is achieved; the station transfer and operation steps of operating personnel are reduced; the workload is reduced; the live working efficiency is improved; the work can be finished by only one person; and both time and labor are saved.

Description

technical field [0001] The invention relates to a lifting device, in particular to a live wire lifter. Background technique [0002] In the live work of live replacement of straight rod insulators and cross-arms, etc., it is often necessary to carry out wire lifting work. The existing operation method is to temporarily support the wires by adding insulating cross-arms, and then perform insulation shielding to complete The replacement of insulators and cross-arms is cumbersome and requires the cooperation of two people. The operation steps are complicated, the tools are heavy, the operator's position is frequently transferred, the workload is large, the operation efficiency is low, and it is time-consuming and laborious. Contents of the invention [0003] The technical task of the present invention is to provide a wire lifter for live work in view of the deficiencies in the prior art above. Reduce the workload, improve the efficiency of live work, only one person can compl...
