Abstract
The utility model relates to the technical field of maintenance and repair devices of an overhead transmission line of the electric power industry, and particularly relates to an overhead ground wire lifter which is a lifting device which is used for overhead ground wire hardware replacement for the high voltage transmission line. A special lifting tool for the 110kV to 220kV transmission line does not exist, thus when overhead ground wire maintenance is carried out, a overhead ground wire is lifted mostly by human, pulleys and other tools, which has the disadvantages of high labor intensity and low operation efficiency. The overhead ground wire lifter provided by the utility model comprises a fixing bracket and a lifting screw. The fixing bracket is provided with a positioning through hole or a positioning groove. The end part of the fixing bracket is provided with a connecting suspension loop. The upper end of the lifting screw is connected with the connecting suspension loop of the fixing bracket through a bolt. The lower end of the lifting screw is provided with an overhead ground wire fixing point. The overhead ground wire lifter provided by the utility model has the advantages that the structure is simple; the operation is convenient; the labor intensity is reduced; the maintenance time is shortened; the work efficiency is improved; and the maintenance work of the sort is offered with convenience.
Description
Technical field
The utility model relates to power industry overhead transmission line maintenance, repair equipment technical field, and specifically a kind of overhead-groundwire lifter, be used for the lifting device that ultra-high-tension power transmission line is changed the overhead ground wire gold utensil.
Background technology
On the shaft tower of ultra-high-tension power transmission line, usually overhead ground wire can be housed.In the operation maintenance work of transmission line, need to check, change the overhead ground wire wire clamp.Because electric pressure, the tower of transmission line are different, the fixed form of overhead ground wire is also different.Particularly the transmission line of 110kV--220kV does not have special-purpose hoisting tool, promote overhead ground wire and mostly adopt manpower pickaback, adopt the instruments such as double hook, pulley, steel wire rope to promote overhead ground wire during shortage of manpower, instrument is loaded down with trivial details, labour intensity is higher, and operating efficiency is low.
Summary of the invention
The purpose of this utility model is to provide a kind of overhead-groundwire lifter, and is easy and simple to handle, overcome deficiency of the prior art.
The technical solution of the utility model is: be comprised of fixed support, lifting leading screw; Fixed support is provided with positioning through hole or location notch; Support bracket fastened end is provided with the connection link; Promote the leading screw upper end and be connected with the support bracket fastened link that is connected by bolt, lifting leading screw lower end is provided with the overhead ground wire fixing point; Described lifting leading screw comprises screw mandrel, swivel nut and ratchet spanner; The two ends of swivel nut respectively are equipped with a screw mandrel that rotation direction is opposite, are equipped with ratchet spanner on swivel nut.
Further, described fixed support is provided with buttress brace.
The utility model has the advantages that: simple in structure, simple operation, solved on different electric pressures and different tower and checked, changed the overhead ground wire gold utensil, a difficult problem that lacks suitable hoisting tool, manpower and instrument resource have been saved, shortened the repair time, improved operating efficiency, for this type of service work is provided convenience.
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is elaborated.

Embodiment
In figure: 1, fixed support; 2, bolt, 3, connect link, 4, buttress brace, 5, screw mandrel, 6, ratchet spanner, 7, the overhead ground wire fixing point.
Embodiment 1
The present embodiment is take the overhead-groundwire lifter that is applicable to plane angle head tower bar cross-arm as example.From Fig. 1---Fig. 2 as can be known, the utility model by fixed support 1, promote leading screw and form; Fixed support 1 is provided with positioning through hole; Fixed support 1 is provided with buttress brace 4; One end of fixed support 1 is provided with and connects link 3; Promote the leading screw upper end and be connected with the link 3 that is connected of fixed support 1 by bolt, lifting leading screw lower end is provided with overhead ground wire fixing point 7.
Described lifting leading screw comprises screw mandrel 5, swivel nut and ratchet spanner 6; The two ends of swivel nut respectively are equipped with a screw mandrel 5 that rotation direction is opposite, are equipped with ratchet spanner 6 on swivel nut.
During work, at first fixed support is fixed 1 appropriate location on overhead ground wire tower bar cross-arm, utilize bolt 2 fastening, make fixed support 1 and the fixation of tower bar cross-arm, then will promote by bolt and be connected link 3 connections on leading screw upper end and fixed support 1.Overhead ground wire is suspended on the overhead ground wire fixing point 7 that promotes the leading screw lower end by tool link or lift lug.After confirming everywhere that connecting portion is reliable and connecting, rotating ratchet spanner 6 tightens up leading screw, promotes overhead ground wire to the gold utensil degree that do not stress, and can check or change the overhead ground wire gold utensil.After maintenance work was complete, backward rotation ratchet spanner 6 loosened the lifting leading screw, and the weight of overhead ground wire is transferred on gold utensil, confirmed gold utensil fixation, unclamped bolt 2, removed to promote leading screw and fixed support 1.
The present embodiment is take the overhead-groundwire lifter that is applicable to facade angle steel tower bar cross-arm as example.From Fig. 3---Fig. 4 as can be known, the present embodiment as different from Example 1, fixed support 1 is provided with the location notch for the facade angle cross arm; The both ends of fixed support 1 are provided with respectively a connection link 3, two connection links 3 and respectively are connected with a lifting leading screw.
Other structure of the present embodiment is identical with embodiment 1.
