Abstract

The utility model discloses an overhead ground wire lifting mechanism, comprising a lead screw, a nut, a sleeve, and a hook. An upper end of the nut is provided with a U-shaped gap, and two side walls of the U-shaped gap are provided with bolt clearing holes. The hook is made of an epoxy resin plate and is connected with the lead screw through a bolt. The nut is rotatably installed on the lead screw. The sleeve is sleeved on the lead screw and is above the nut. The sleeve is provided with an overhead ground wire supporting hook. The nut is provided with a forcing handle. The hook is hung on a hanging pole arm of the overhead ground wire, the overhead ground wire supporting hook holds up the overhead ground wire, and the forcing handle is rotated, so that the nut drives the sleeve to move upward, and the overhead ground wire supporting hook on the sleeve drives the ground wire to move upward. Thus, straight overhead ground wire armour clamp can be changed in live working. Compared with the prior art, the overhead ground wire lifting mechanism solves problems of poor reliability, having potential safety hazard, and high labor intensity of operating personnel using a former working method of pickaback. Simultaneously, the overhead ground wire lifting mechanism is suitable for pole arms of U-steel and angle iron.

Description

Overhead-groundwire lifter
Technical field
The utility model relates to a kind of electrician's instrument, especially a kind of overhead-groundwire lifter.
Background technology
In electrified replacing linear overhead ground wire gold utensil process, the operating personnel carries out the replacing of gold utensil after adopting and leaning on manpower mode pickaback that overhead ground wire is held up again at present.But this way security reliability is poor pickaback, and labour intensity is large, is prone to accidents.Therefore, designing a kind of overhead-groundwire lifter of electrified replacing linear overhead ground wire gold utensil, is the present technical issues that need to address.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of overhead-groundwire lifter of electrified replacing linear overhead ground wire gold utensil.
The technical scheme in the invention for solving the technical problem is:
Overhead-groundwire lifter, by leading screw, screw, sleeve and hook form, upper end at screw is provided with " U " breach, there is bolt to pass through the hole on the two side of " U " breach, hook is made by epoxy resin board, and hook is connected with leading screw by bolt, and the screw spinning is at leading screw, sleeve set is on leading screw, sleeve is provided with the overhead ground wire hook on the top of screw at sleeve, and screw is provided with afterburning handgrip, hook is hung over overhead ground wire to be hung on the cross-arm, the overhead ground wire hook is held overhead ground wire, rotates afterburning handgrip, and screw just is with moving sleeve to move up, overhead ground wire hook on the sleeve drives ground wire and moves up together, can electrified replacing linear overhead ground wire gold utensil.
Preferably, described hook is for being fit to the angle hook of angle bar cross-arm, and is hinged with an end of auxiliary rod by the first bearing pin at the middle part of the hook handle of angle hook, is hinged with the straight hook hook of suitable channel-section steel cross-arm by the second bearing pin at the other end of auxiliary rod.
Preferably, described straight hook hook is double-head hanger, and the hook at two is fit to respectively the channel-section steel of different model.
Compared with prior art, pickaback method of work poor reliability before the utility model has solved exists potential safety hazard, problem that operating personnel's labour intensity is high; Simultaneously, the utility model is all applicable to channel-section steel, angle cross arm.
