Abstract
The utility model discloses an overhead ground wire lifter, relates to a power system, and specifically discloses a device for lifting an overhead ground wire. The overhead ground wire lifter comprises a fixation bracket and mechanical lifting devices. The upper portion of each mechanical lifting device is connected with the fixation bracket. Each lifting device comprises a base, a gear, a rack, an operating handle and a lifting hook. The gear is installed onto the base through a bolt. The operating handle is arranged on the gear shaft. One end of the operating handle is fixed through the gear shaft. The operating handle can be rotated around the gear shaft. The non-return function can be realized. The rack is engaged with the gear. The tail end of the rack is provided with the lifting hook. At least two sets of mechanical lifting devices exist. The overhead ground wire lifter has advantages of structure reasonable and convenient installation and utilization, and can be used to lift an overhead ground wire upwards; advantages of easy operation, time saving and labor saving can be realized, and the labor efficiency can be improved.
Description
Technical field
A kind of overhead-groundwire lifter of the utility model 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.
Utility model content
The purpose of this utility model is to provide 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 utility model is described in further detail:
Fig. 1 is the structural representation of a kind of overhead-groundwire lifter of the utility model.
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.
