Abstract
The invention discloses a power transmission line installation tool and particularly relates to an overhead ground wire lifter of a power transmission line. The overhead ground wire lifter comprises a base (1), two adjusting boards (2), two double-end lead screws (3) and two hooks (4). Adjusting screw holes (5) are evenly arranged on the two adjusting boards (2), two sides of the base (1) are respectively connected with the adjusting boards (2) through adjusting bolts (6) matched with the adjusting screw holes (5), the tops of the double-end lead screws (3) are hinged to the bottoms of the adjusting boards (2), and the bottoms of the double-end lead screws (3) are connected with the hooks (4). The overhead ground wire lifter has the advantages of being good in generality, convenient to operate and capable of effectively reducing construction risks.
Description
Technical field
The present invention relates to a kind of transmission line erecting tools, be specifically related to a kind of transmission line aerial earth wire lifter.
Background technology
Part electric power overhaul unit generally adopts manpower mode or respective model steel tower lifter special that overhead ground wire is ploughed under in the releasing pulley when carrying out power transmission line overhead ground wire replacing construction at present.Because the transmission line span is long, overhead ground wire weight large (220kV transmission line span is generally 300-400 rice, as is that 500KV transmission line span is larger, and overhead ground wire is about about 600 kilograms in the stressed place of shaft tower weight).As the work of adopting manpower to change overhead ground wire needs 2-3 people's work compound overhead ground wire could be put into releasing pulley.But because the steel tower headroom is limited, comparatively appropriate setting can only hold 1 staff usually, and other cooperations personnel can not enter desirable setting, cause changing the inefficiency of overhead ground wire, and security risk is high.For example the 220KV power transmission line overhead ground wire more changes jobs, and needs 2-3 people's cooperation on the 1 basic steel tower, approximately needs overhead ground wire could be turned over into releasing pulley in 1-2 hour.As adopt the lifter special of respective model, although a people also can put into releasing pulley with overhead ground wire fast, but electric power overhaul unit need to purchase special-purpose lifter in a large number according to the steel tower model, virtually increased the production and operation cost of enterprise, development along with the electrical network scale, a large amount of high pressure and the operation of extra high voltage line input coefficient, the wire diameter of overhead ground wire is increasing, lifter in the market also exists versatility not strong, the scope of application is little, only can be applicable to the lifting of the overhead ground wire of wire diameter less, the load of lifting can not satisfy the needs of power grid construction, is unfavorable for the safety in production of enterprise.
Summary of the invention
The object of the present invention is to provide a kind of transmission line aerial earth wire lifter, having solved overhead ground wire, to plough under the instrument scope of application of releasing pulley single, need to use different instruments according to different models, cause cost to improve the problem of the wasting of resources.
For solving above-mentioned technical problem, the present invention is by the following technical solutions: a kind of transmission line aerial earth wire lifter, comprise base, two adjustment plate, two double end screw mandrels and two hooks, evenly be provided with the adjustment screw on described two adjustment plates, the both sides of described base are connected with the adjustment plate by the adjustment bolt suitable with adjusting screw respectively, the top of described double end screw mandrel is hinged with the bottom of adjusting plate, and the bottom of double end screw mandrel is connected with hook.
Further technical scheme is to be socketed with spanner on the above-mentioned double end screw mandrel.
Compared with prior art, the invention has the beneficial effects as follows: versatility is good: the applicable 220KV of this finished product and all forthright towers of above transmission line; Easy to operate: this finished product can be by 1 people easy manipulation on steel tower; Efficiency of construction is high: the staff is promoting overhead ground wire fast and is moving, and relatively original construction method saves time about 3/4; Effectively reduce construction risk: owing to reduced workmen's quantity and physical demands, greatly improved the safety and reliability of work progress.

Another embodiment of transmission line aerial earth wire lifter is socketed with spanner 7 on the double end screw mandrel 3 according to the present invention.
This transmission line aerial earth wire lifter in use, can be according to actual using area, height and steel tower model, utilize the adjustment screw 5 of adjusting on the version 2 and the cooperation of adjusting between the bolt 6 to adjust, first base 1 is bolted on the top of steel tower overhead ground wire hitch point, then with hook 4 overhead ground wire caught on, by the rotation of double end screw mandrel 3, can realize fast lifting and the decline of overhead ground wire.
Although invention has been described with reference to a plurality of explanatory embodiment of the present invention here, but, should be appreciated that those skilled in the art can design a lot of other modification and execution modes, these are revised and execution mode will drop within the disclosed principle scope and spirit of the application.More particularly, in the scope of, accompanying drawing open in the application and claim, can carry out multiple modification and improvement to building block and/or the layout of subject combination layout.Except modification that building block and/or layout are carried out with improving, to those skilled in the art, other purposes also will be obvious.
Claims (2)
1. transmission line aerial earth wire lifter, it is characterized in that: comprise base (1), two adjustment plate (2), two double end screw mandrels (3) and two hooks (4), evenly be provided with on described two adjustment plates (2) and adjust screw (5), the both sides of described base (1) are connected with adjustment plate (2) by the adjustment bolt (6) suitable with adjusting screw (5) respectively, the top of described double end screw mandrel (3) is hinged with the bottom of adjusting plate (2), and the bottom of double end screw mandrel (3) is connected with hook (4).
