Abstract

The utility model relates to the technical field of high-voltage power transmission line maintenance equipment in the electric power industry, specifically to a live-line fastening tool for a bolt of a strain clamp of a power transmission line. When the high-voltage power transmission line operates for a long time, the connecting bolt of a drainage plate of the strain clamp may become loose. Generally, an equipotential mode is adopted for live-line fastening, the number of needed work personnel is relatively large, the operation procedure is complex, and the danger coefficient is relatively high. The live-line fastening tool of the utility model is composed of an insulating operation rod, a junction plate, a ratchet wrench, and a control rope, wherein the junction plate is fixed on the top end of the insulating operation rod; the middle part of a handle of the ratchet wrench is hinged and connected with the junction plate through a shaft; and the insulated control rope is connected to the tail end of the handle of the ratchet wrench. The live-line fastening tool of the utility model is advantaged in that the tool is simple in structure and convenient to operate; the work personnel can complete the live-line operation of fastening of the bolt of the strain clamp by standing on a cross arm of a tower; the personal safety of the maintenance personnel is guaranteed; the labor is saved and the labor intensity is reduced; and the work efficiency is increased.

Description

A kind of Electrified fastening instrument of tension-resistance cleat for transmission line bolt
Technical field
The utility model relates to power industry ultra-high-tension power transmission line maintenance of equipment technical field, for the power-on serving of 220kV tension-resistance cleat for transmission line, and a kind of Electrified fastening instrument of tension-resistance cleat for transmission line bolt specifically.
Background technology
Ultra-high-tension power transmission line moves for a long time in natural environment, the transmission line in cross-domain especially mountain area, the impact that is subject to the factors such as wind, rain is descended, the connecting bolt of its strain clamp drainage plate, there will be loosening phenomenon, if fastening maintenance is carried out in outage, can cause zone to have a power failure, affect user's daily life and work, therefore usually adopt equipotential mode Electrified fastening, be that the maintenance personal enters electric field and directly contacts drainage plate and carry out maintenance work, need staff's number more, the program complexity, danger coefficient is higher, engineering time is long, and operating efficiency is lower.
Summary of the invention
The purpose of this utility model is to provide a kind of Electrified fastening instrument of tension-resistance cleat for transmission line bolt, to overcome deficiency of the prior art, has reduced labour intensity, has guaranteed workmen's personal safety, has improved operating efficiency.
The technical solution of the utility model is: insulating bar, joint cover, ratchet spanner, tricing line, consist of; Joint cover is fixed on the top of insulating bar, and the handle middle part of ratchet spanner is articulated and connected by axle and joint cover, and the tricing line of insulation is connected to the end of the handle of ratchet spanner.
Further, effective insulated lengths of described insulating bar is not less than 2.1 meters.
The utility model has the advantages that: simple in structure, convenient operation, the staff is positioned on cross arm of tower and can utilizes the hot line job of the utility model instrument to complete the fastening of strain clamp bolt, guaranteed maintainer's personal safety, solved prior art medium-high voltage transmission lines road strain clamp bolt loosening, need the problem that has a power failure or adopt the equipotential mode to keep in repair, saved manually, improved operating efficiency.
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is elaborated.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
In figure: 1, joint cover, 2, insulating bar, 3, ratchet spanner, 4, tricing line.
Embodiment
As can be seen from Figure 1, the technical solution of the utility model is: insulating bar 2, joint cover 1, ratchet spanner 3, tricing line 4, consist of; Joint cover 1 is fixed on the top of insulating bar 2, and the handle middle part of ratchet spanner 3 is articulated and connected by axle and joint cover 1, and the tricing line 4 of insulation is connected to the end of the handle of ratchet spanner 3.
Effective insulated lengths of described insulating bar 2 is not less than 2.1 meters, guarantees that the staff is positioned at outside safe distance.
During work, by two staff, stood on cross arm of tower, respectively hold a set of the utility model fastened tools compounding practice.Wherein operating personnel first hold this instrument, utilize the ratchet spanner 3 of insulating bar 1 end to entangle the bolt head of strain clamp bolt, are fixed; Another operating personnel hold another set of fastened tools, with ratchet spanner 3, entangle nut loosening on strain clamp bolt, by adjusting insulating bar 2, and pull the tricing line 4 of insulation, by this tie point bolted, can complete fastening operation.
Finally should be noted that: above embodiment is for illustrating that the technical solution of the utility model is not intended to limit; the those skilled in the art modifies to execution mode or the part technical characterictic is equal to replacement; and do not break away from the essence of technical solutions of the utility model, within all should being encompassed in the utility model scope required for protection.
