Abstract

The utility model discloses a fixing device of a transmission wire lifter, which is provided with a base body matched with a lifter lead screw. L-shaped hanging lugs are arranged on two sides of the base body. The fixing device enables the lifter to be stably hung on a cross arm, is convenient to perform wire lifting operation, and can prevent the lead screw from shifting and dropping when the wire lifting operation is performed, thereby reducing labor intensity, and improving operation efficiency. The fixing device of the transmission wire lifter also has the advantages of being simple in structure, convenient to operate, strong in practical applicability and the like.

Description

A kind of transmission pressure line lifter fixture
Technical field
The utility model belongs to transmission line erecting tools technical field, particularly a kind of transmission pressure line lifter fixture.
Background technology
In the lifting operation of power system transmission line heavy in section multiple fission conductor in maintenance; The conventional method of carrying out transmission pressure 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.At present, special-purpose line lifter is adopted in the construction that has, and this line lifter is by carrying the line suspension hook, carrying the line plate and screw mandrel is formed; The screw mandrel upper end is provided with nut, and when construction, nut places on the cross-arm of power transmission line column bar; Through rotating nut, carry the line plate, propose the up of line suspension hook through the screw mandrel drive.Though this line lifter operation is easier; The fail safe of carrying line than conventional method improves greatly, still, because line lifter is suspended on the cross-arm by nut support fully; Need the turn nut when proposing the line operation in addition; Therefore line lifter is unstable, brings very burden to operation, and screw mandrel comes off from two angle bar gaps of cross-arm easily.
The utility model content
The purpose of the utility model is to provide a kind of line lifter that can make stably to be suspended on the cross-arm, makes things convenient for lead to promote operation, and can prevent coming off of screw mandrel, reduces labor intensity, and improves the transmission pressure line lifter fixture of operating efficiency.
The technical scheme that purpose adopted that realizes the utility model is: a kind of transmission pressure line lifter fixture, have a pedestal that cooperates with the line lifter screw mandrel, and the both sides of this pedestal are provided with L shaped hangers.
The external diameter of said pedestal and the width of hangers are all less than the gap between power transmission line column bar cross-arm two angle bar.
The transmission pressure line lifter fixture of the utility model can make line lifter stably be suspended on the cross-arm, proposes the line operation easily; And the moving and come off of screw mandrel can prevent to propose the line operation time; And reduce labor intensity thus, improving operating efficiency, this device also has simple in structure; Easy to operate, advantage such as practical.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
Referring to Fig. 1, the transmission pressure line lifter fixture of the utility model has a pedestal 1, and the centre of this pedestal 1 is provided with through hole, is used for the cooperation that installs with line lifter screw mandrel 4.Be provided with L shaped hangers 2 in the both sides of pedestal 1, be used for and the articulating of power transmission tower bar cross-arm angle bar 3.The width of the external diameter of said pedestal 1 and hangers 2 like this, is convenient to pass the gap of fixture between cross-arm two angle bar 3 all less than the gap between power transmission line column bar cross-arm two angle bar 3.This device can be installed on it earlier on the line lifter screw mandrel 4 in use, the nut 5 of line lifter is screwed in the upper end of screw mandrel 4 again; Then this device is passed the gap between power transmission line column bar cross-arm two angle bar 3 from the below; And rotate 90 °, and be hooked on by said hangers 2 on two jiao of 3 iron of cross-arm, can make line lifter stably be suspended on the cross-arm; Propose line operation easily, screw mandrel moves and comes off in the time of can preventing simultaneously to propose the line operation.

Claims (2)

1. transmission pressure line lifter fixture, it is characterized in that: it has a pedestal that cooperates with the line lifter screw mandrel, and the both sides of this pedestal are provided with L shaped hangers.
2. a kind of transmission pressure line lifter fixture as claimed in claim 1 is characterized in that: the external diameter of said pedestal and the width of hangers are all less than the gap between power transmission line column bar cross-arm two angle bar.
