Abstract
The invention discloses an overhead ground wire lifter, which comprises a clamping groove. Support arms are arranged on two sides of the clamping groove, the ends of the two support arms are provided with a lead screw respectively, and the lower parts of the lead screws are provided with wire hanging devices. The support arms have hollow structures, movable support arms are inserted into the hollow support arms, the lead screws are arranged at the ends of the movable support arms, and the support arms and the movable support arms are fixed by positioning pins. The overhead ground wire lifter has simple structure and low cost, is very convenient to operate, can complete wire lifting overhauling operation of an overhead ground wire of over 220 thousand volts by one operator, and is safe and time-saving.
Description
Technical field
The present invention relates to a kind of line apparatus of carrying, be specially a kind of line lifter that is used for overhead ground wire repair and maintenance process.
Background technology
, carrying out the aerial condutor maintenance when (as changing wire clamp, changing overhead ground wire), overhead ground wire need be mentioned, the method for use generally is by one or two human shoulder overhead ground wire to be lifted with hands, carries out upkeep operation by other people then in the past.This mode labour intensity is big, especially is absolutely unsafe; Big as load, shoulder not that time-out then needs assembly pulley, need on the tower that the more work personnel carry out coordinating operation under the tower this moment, also utilize 2 double hook wire grips that ground wire is mentioned sometimes, it is complicated that this operation also shows, and dangerous.
Summary of the invention
The present invention is directed to the deficiency that above-mentioned prior art exists, designed a kind of overhead ground wire line lifter, solved Personal Risk and the ineffective defective brought by manual operation when carrying out the overhead ground wire maintenance at present.
A kind of overhead ground wire line lifter of the present invention is characterized in that comprising a draw-in groove, is fixed with support arm in the both sides of draw-in groove, and the end of two support arms is respectively arranged with leading screw, and the leading screw bottom is provided with thread-laying device.
Described overhead ground wire line lifter, support arm wherein are hollow structure, are inserted with movable arms in the hollow support arm, and leading screw is arranged on the end of movable arms, are fixed by shop bolt between support arm and the movable arms.
Described overhead ground wire line lifter, thread-laying device wherein is hook or snap ring.
Overhead ground wire line lifter of the present invention, simple in structure, cost is very low, and is easy to operate, and what only need that operating personnel can finish 220,000 volts above high-altitude ground wires carries line upkeep operation and safe saving time.

Embodiment
Describe overhead ground wire line lifter of the present invention in detail below in conjunction with accompanying drawing.
Overhead ground wire line lifter shown in Fig. 1-2 has a draw-in groove 4, be fixed with support arm 1 in the both sides of draw-in groove 4, this support arm 1 is a hollow structure, be inserted with movable arms 2 therein, the end of movable arms 2 is fixed with leading screw 5, there is chain leading screw 5 lower ends and places the thread-laying device 7 of chain ends, and the length of chain is adjustable fixed structure.If do not adopt movable arms, leading screw 5 directly can be fixed on support arm 1 end.A handle 3 is arranged on leading screw top.A fixing hole is arranged on the support arm 1, and equidistant several fixing holes that is provided with on the movable arms by the said fixing hole, are connected and fixed or adjust the collapsing length of movable arms by pin 6 between support arm 1 and the movable arms 2.
During use, carry on a shoulder pole line lifter draw-in groove 4 on the vertical surface of two angle bar in end with being stuck in, with bolt, the length of adjusting both sides movable arms 5 is to correct position, respectively two hooks are tangled the both sides of overhead ground wire, adjust chain length and fixing, turning handle 3 then, and line lifter is mentioned ground wire lentamente.At this moment, the gold utensil complete discharge that the ground load goes up overhead ground wire can carry out upkeep operation to it.
Described line lifter support arm adopts square steel to make.All parts such as hook, chain all need pass through the standard testing of electric power tool safety detection.
