Abstract
The invention discloses an overhead ground wire lifter, and relates to electric systems, in particular to an overhead ground wire lifting device. The overhead ground wire lifter comprises a fixing frame and mechanical lifting devices. The upper portions of the mechanical lifting devices are connected with the fixing frame. Each mechanical lifting device comprises a base, a gear, a rack, an operating handle and a lifting hook. The gears are installed on the bases through bolts, the operating handles are arranged on gear shafts, one ends of the operating handles are fixed through the gear shafts and can rotate around the gear shafts, and the stopping preventing function is achieved. The racks are meshed with the gears. The lifting hooks are installed at the tail ends of the racks. The number of the mechanical lifting devices is at least two. The overhead ground wire lifter is reasonable in structure, convenient to install and use and easy to operate, an overhead ground wire can be rapidly upwards lifted, time and labor are saved, and the labor efficiency is improved.
Description
Technical field
A kind of overhead-groundwire lifter of the present invention relates to electric power system, is a kind of device promoting for overhead ground wire.
Background technology
Power system transmission line is all furnished with built on stilts earth connection at present, and built on stilts earth connection hangs over tower end by link and wire clamp, accumulates over a long period, and link and wire clamp there will be wearing and tearing, need charged replacing.But link and wire clamp are very near apart from tower end, there is no ready-made specific purpose tool, changing wire clamp work wastes time and energy, and has certain danger.
Existing instrument is all to adopt fixed mount to add what bolt promoted, and bolt needs people to use wrench operated, needs to overcome the weight of built on stilts earth connection in addition, operating difficulties, and efficiency is low.
Summary of the invention
The object of the invention is provides a kind of overhead-groundwire lifter for above-mentioned weak point, can upwards mention making somebody a mere figurehead earth connection fast, solves the problem of changing built on stilts earthing wire clip difficulty, raises labour efficiency.
A kind of overhead-groundwire lifter takes following technical scheme to realize: a kind of overhead-groundwire lifter comprises fixed mount and mechanical lifting device, the top of mechanical lifting device is connected with fixed mount, described lifting device comprises pedestal, gear, tooth bar, operating grip and suspension hook, gear is arranged on pedestal by bolt, operating grip is arranged on gear shaft, described operating grip one end is fixed by gear shaft, can rotate around gear shaft, with anti-return-stopping function; Rack and pinion is meshed; Tooth bar end is provided with suspension hook; Described mechanical lifting device is no less than two covers.
When overhead-groundwire lifter uses, fixed mount is stuck in to tower end, suspension hook hangs on built on stilts earth connection, and rotating operation handle will be maked somebody a mere figurehead earth connection and upwards be promoted, and operating personnel can change wire clamp smoothly; Change complete after, operating grip is upwards pushed away, the downward landing of suspension hook, built on stilts earth connection returns to origin-location.
A kind of overhead-groundwire lifter is rational in infrastructure, easy to install, can upwards mention making somebody a mere figurehead earth connection fast; Simple to operate, time saving and energy saving, raise labour efficiency.
Brief description of the drawings
Below with reference to accompanying drawing, the invention will be further described:
Fig. 1 is the structural representation of a kind of overhead-groundwire lifter of the present invention.
In figure: 1, fixed mount, 2, pedestal, 3, gear, 4, tooth bar, 5, operating grip, 6, suspension hook, 7, gear shaft.
Embodiment
With reference to accompanying drawing 1, a kind of overhead-groundwire lifter comprises fixed mount 1 and mechanical lifting device, the top of mechanical lifting device is connected with fixed mount 1, described lifting device comprises pedestal 2, gear 3, tooth bar 4, operating grip 5 and suspension hook 6, gear 3 is arranged on pedestal 2 by bolt, and operating grip 5 is arranged on gear shaft 7, and described operating grip 5 one end are fixing by gear shaft 7, can rotate around gear shaft 7, with anti-return-stopping function; Tooth bar 4 and gear 3 are meshed; Tooth bar 4 ends are provided with suspension hook 6; Described mechanical lifting device is no less than two covers.
When overhead-groundwire lifter uses, fixed mount 1 is stuck in to tower end, suspension hook 6 hangs on built on stilts earth connection, and rotating operation handle 5 will be maked somebody a mere figurehead earth connection and upwards be promoted, and operating personnel can change wire clamp smoothly; Change complete after, operating grip 5 is upwards pushed away, the downward landing of suspension hook 6, built on stilts earth connection returns to origin-location.
