Abstract
The invention relates to an overhead ground wire lifter which comprises a rack body and lifting rods and is characterized in that the center of the rack body is provided with a through groove with a downward opening, two ends of the rack body are provided with screw holes, each lifting rod of which the surface is provided with threads is arranged in each screw hole, the upper part of each lifting rod is provided with a spanner and the lower end of each lifting rod is provided with a hanging wire hook. According to the overhead ground wire lifter, a double-lifting-point lifting structure is adopted, other protection measures are not needed to be taken during operation, so that the fieldwork quantity is reduced, and the efficiency is improved; the generality is strong, by virtue of controlling the width size of the groove of the rack body, the overhead ground wire lifter can adapt to all existing tower shapes of 220-500Kv; the lifting stroke of the lifting rod is long, so that the operation requirements can be met; the overhead ground wire lifter is simple in structure and convenient to use.
Description
Technical field
The present invention relates to a kind of power equipment maintaining instrument, particularly a kind of overhead-groundwire lifter 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, improve the visual plant of circuit safety in operation, owing to open-air wind-force reason, overhead ground wire can frequently swing 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.This class instrument ubiquity that at present electric power system is used is following not enough: the one, and for security consideration, instrument upper end suspension centre is not high enough, causes the distance between suspension centre and the overhead ground wire less, overhead ground wire can't be risen to the degree that can change; The 2nd, instrument is the lifting of single suspension centre, must take to prevent the backup protection measure that comes off to have increased the work on the spot amount to overhead ground wire in operation; The 3rd, the instrument versatility is poor, because on-the-spot tower is uncertain, each operating personnel must prepare two or more hoisting tools, just can't change otherwise type is different.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of overhead-groundwire lifter that adopts two suspension centres and highly versatile is provided.
The object of the present invention is achieved like this: a kind of overhead-groundwire lifter, comprise support body and lifting arm, and it is characterized in that support body central authorities are provided with the groove of opening down perforation, the support body two ends are provided with screw, are provided with the surface in the screw and are 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.
Characteristics of the present invention are: adopted two suspension centre hoisting structures, needn't take other safeguard measures in the operation again, reduced the work on the spot amount, improved efficient; Highly versatile by 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 structural representation of the present invention.
Embodiment
The invention will be further described below in conjunction with accompanying drawing:
As shown in Figure 1: support body of the present invention 1 central authorities 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 the threaded lifting arm 3 of surface band is arranged in the support body screw, can make lifting arm mobile in the support body screw by rotation.The top of lifting arm is provided with spanner 4, and its effect is to be convenient to rotate and upgrade 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, first support body is placed on the cross-arm of shaft tower, spanner on two lifting arms of difference turn, make lifting arm drop to the position that wire-hanging hook can tangle overhead ground wire, 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 the operations such as gold utensil.
