Abstract
The utility model discloses a live-working double-conductor lifting device. The live-working double-conductor lifting device consists of a conductor lifting hook, a pulling plate, a lead screw and a nut which is matched with the lead screw, wherein the pulling plate passes through and is arranged in a through hole formed in the conductor lifting hook, and is connected with the conductor lifting hook through a positioning dowel; and the lead screw is connected to the upper end of the pulling plate. The conductor lifting device can reduce labor intensity, improve operation efficiency, and effectively strengthen the safety of live working, and also has the advantages of simple structure, convenience for operation, high practicability and the like.
Description
Technical field
The utility model belongs to transmission line erecting tools technical field, particularly a kind of live line working two-conductor line line lifter.
Background technology
In the electric power system Overhead Transmission Line Construction; The method of carrying out two-conductor line lifting installation is normally stood on the cross-arm of tower bar by the operator; There is the outstanding rope of simple and easy thread-lifting hook that two leads are promoted to the height that needs by root through two root systems; And will hang rope and be bundled in respectively on the cross-arm, after treating lead is strained and fixed, untie again and take off outstanding rope.The major defect one of this method is to lean on manpower to promote two leads one by one fully, wastes time and energy, and labour intensity is big, and operating efficiency is low; The 2nd, thread-lifting hook adopts the steel plate cutting to form, and makes coarsely, causes easy damaged lead when carrying line; The 3rd, altitude hot-line operation, supporting surface is narrow and small, astasia, not only very inconvenience of operation, and seriously have potential safety hazard.
The utility model content
The purpose of the utility model is to provide a kind of and can reduces labor intensity, and improves operating efficiency, and the live line working two-conductor line line lifter of handling safety.
The technical scheme that purpose adopted that realizes the utility model is: a kind of live line working two-conductor line line lifter; By lead suspension hook, arm-tie, screw mandrel and with it nut engaged form; Wherein, Arm-tie is installed in the through hole that is provided with on the lead suspension hook, and is connected through shop bolt, and screw mandrel is connected the upper end of arm-tie.
Said lead suspension hook is a double-hung anchor shape structure.
The suspension hook position of said lead suspension hook is provided with a watt shape liner plate.
The live line working two-conductor line line lifter of the utility model can reduce labor intensity, and improves operating efficiency, and can strengthen the fail safe of live line working effectively, and this line lifter is simple in structure, and is easy to operate, practical.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to Fig. 1; The live line working two-conductor line line lifter of the utility model, by lead suspension hook 1, arm-tie 2, screw mandrel 5 and with it nut engaged 6 form, wherein; Being provided with the cross section in the middle part of lead suspension hook 1 is rectangular through hole; Arm-tie 2 is installed in this through hole, and is fixedly connected through shop bolt 4, and screw mandrel 5 is connected the upper end of arm-tie 2.Lead suspension hook 1 is a double-hung anchor shape structure, is used for the lifting suspension of two-conductor line.On the suspension hook position of lead suspension hook 1, be fixed with a watt shape liner plate 3,, prevent the lead damage to strengthen lead suspension contact area.This line lifter in use; It is suspended on the cross-arm of shaft tower through said nut 6; Again two high voltage electricity transmission conductive wires to be installed are promoted and be suspended on the lead suspension hook 1; Can make screw mandrel 5 drive the optimum height that arm-tie 2, lead suspension hook 1 and high voltage electricity transmission conductive wire rise to suitable installation by turn nut 6 this moment, can carry out installing and fixing of high voltage electricity transmission conductive wire easily.Promote and install and fix in the process at high voltage electricity transmission conductive wire, operating personnel's operation that need not to stand has guaranteed the safe distance of operating personnel and top electrified body and the safety of live line working thus, and has improved operating efficiency.
