Abstract
The utility model relates to an overhead ground wire lifter which comprises a frame and lifting rods. The overhead ground wire lifter is characterized in that a groove with a downwardly communicating opening is arranged in the center of the frame, screw holes are disposed at two ends of the frame, and the lifting rods with threads on surfaces are arranged in the screw holes. A lever is arranged on the upper portion of each lifting rod, and a wire hanging hook is disposed at the lower end of each lifting rod. A hoisting structure with double hoisting points is adopted, other protection measures are omitted during operation, field workload is reduced, and efficiency is improved. In addition, the overhead ground wire lifter is high in universality, and is applicable to all existing towers with voltage ranging from 220 kilovolts to 500 kilovolts by means of controlling the width of the groove of the frame. Besides, the lifting stroke of each lifting rod is long, and operation requirements can be met. Further, the overhead ground wire lifter is simple in structure and convenient to use.
Description
Technical field
The utility model relates to a kind of electric power maintenance tool, particularly a kind of overhead ground wire lifter that is used for the ultra-high-tension power transmission line Maintenance and Repair.
Background technology
Overhead ground wire in the ultra-high-tension power transmission line is to reduce the damage to crops caused by thunder accident, improves the visual plant of circuit safety in operation, owing to open-air wind-force reason; Overhead ground wire can frequently be swung and shake brokenly, thereby causes the gold utensil serious wear of carrying overhead ground wire, if untimely discovery and changing; Will cause the gold utensil fracture; Overhead ground wire come off and with the major accident of wire electrical discharge, for this reason, must often carry out examination and maintenance to overhead ground wire.When maintenance or replacing overhead ground wire gold utensil, need to use specific instrument that overhead ground wire is sling.Not enough below this kind tool ubiquity that electric power system is at present used: the one, from security consideration, instrument upper end suspension centre is not high enough, causes the distance between suspension centre and the overhead ground wire less, can't overhead ground wire be risen to the degree that can change; The 2nd, instrument is the lifting of single suspension centre, in operation, must take to prevent the backup protection measure that comes off to have increased the work on the spot amount to overhead ground wire; The 3rd, the instrument versatility is poor, because on-the-spot tower is uncertain, each operating personnel must prepare two or more lifting instruments, just can't change otherwise type is different.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art, and a kind of overhead ground wire lifter that adopts two suspension centres and highly versatile is provided.
The purpose of the utility model is achieved in that a kind of overhead ground wire lifter, comprises support body and lifting arm, it is characterized in that support body central authorities are provided with the groove that opening connects down, and the support body two ends are provided with screw, is provided with the surface in the screw and is the lifting arm of screw thread.
Described lifting arm top is provided with spanner, and the lifting arm lower end is provided with wire-hanging hook.
The characteristics of the utility model are: adopted two suspension centre lifting structures, needn't take other safeguard measures again in the operation, reduced the work on the spot amount, improved efficient; Highly versatile through control support body recess width size, goes for adapting to existing 220 kilovolts of-500 kilovolts of whole turriforms; The lift stroke of lifting arm is long, can satisfy the operation needs; Simple in structure, easy to use.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1: support body 1 central authorities of the utility model are provided with downward opening perforation groove 2, and the effect of this groove is that support body is more firmly placed on the cross-arm of high pressure shaft tower.The support body two ends are provided with screw, and surperficial screwed lifting arm 3 is arranged in the support body screw, through rotation lifting arm are moved in the support body screw.The top of lifting arm is provided with spanner 4, and its effect is to be convenient to the rotary lifting bar.The lifting arm lower end is provided with wire-hanging hook 5, in order to tangle the overhead ground wire of preparing lifting.
During use; Earlier support body is placed on the cross-arm of shaft tower, the spanner on two lifting arms of turn makes lifting arm drop to the position that wire-hanging hook can tangle overhead ground wire respectively; After wire-hanging hook tangles overhead ground wire; The turn spanner rises lifting arm again, overhead ground wire is promoted to desired height after, can change operations such as gold utensil.
