Description

A sleeve-type combination tool for fastening and draining wire clips

technical field

The utility model belongs to the technical field of live maintenance of transmission lines, and relates to a live maintenance tool. The utility model relates to the live maintenance of overhead transmission lines, especially for the indirect operation of single-circuit tension tower (rod) drainage wire clamp heating defects and the live treatment of the heating defects of overhead power transmission line drainage wire clamps in the same tower multi-circuit vertical arrangement mode. The utility model relates to a live maintenance tool for an overhead power transmission line.

Background technique

With the rapid development of the economy and the continuous expansion of the scale of the power grid, the number of overhead transmission lines increases, the load of transmission lines increases, and the defects of line drainage clamps heating are more and more. If the power supply enterprise wants to improve the reliability of power supply, it is necessary to optimize the treatment method for eliminating the heating defect of the drain wire clamp when it is live. At present, there are two ways to deal with the heating defect of the drain wire clip. The first is that the equipotential workers enter the strong electric field to work; the second is that the workers deal with it after an emergency power failure. The first operation method, because the equipotential method is used for processing, the equipotential operation personnel must enter and exit the strong electric field, which has high safety risks, high labor intensity, high cost, and low efficiency; the second operation method uses emergency power outages to reduce power supply Reliability rate increases power grid risk. In view of the disadvantages of the above two operation methods, and at the same time, in order to shorten the operation time, improve work efficiency, and reduce the risk of operation safety, it is necessary to develop a tool that can not only avoid power outage processing, but also use live mode to deal with this defect.

Contents of the invention

The purpose of the utility model is to provide a combination tool for fastening and draining wire clamps with electricity in order to overcome the above-mentioned defects in the prior art, thereby solving the problems in the prior art.

The problem to be solved by the utility model is that the existing technology cannot realize the electrification treatment of the heating defect of the drainage wire clip of the single-circuit tension tower (rod) and the heating defect of the overhead transmission line vertically arranged in the same tower with multiple circuits.

The technical scheme adopted by the utility model is: a sleeve-type combined tool for fastening and draining wire clips with electricity. It consists of a handle, a closed nut wrench at one end of the handle, and a pier head at the other end of the handle; one end of the sleeve is provided with an inner nut hole, and the other end is provided with an outer nut; It is composed of through-hole bolts and nuts; the insulating operating rod is composed of a shaft and a clamping head located at one end of the shaft, which is smaller than the cross-sectional shape of the shaft and has a bolt connection hole; the connection structure is that the clamp of the connecting component clamps the socket wrench The fastening hole on one side of the fixture penetrates the through-bolt and the nut is used to tighten the through-bolt; the outer nut section of the sleeve is inserted into the closed nut wrench of the socket wrench to form a combined tool.

The tool of the utility model is a new tool for carrying out electrified fastening of the drainage wire clip bolts after installing and fixing the fixture at the handle of the socket wrench and assembling and connecting with the insulating operating rod. The combination tool for fastening and draining clamps with electricity uses the principle of lever transmission to turn and extend the moment arm of the socket wrench, so that personnel can fasten long-distance bolts only by standing on the iron tower. The use of this tool can prevent personnel from entering the strong electric field, reducing the operation risk; reducing the number of operators, reducing the cost and labor intensity of the operators.

The beneficial effects of the utility model are: the tool of the utility model will solve the indirect operation of single-circuit tension-resistant drain wire clip heating and the processing of the heat generation defect of the overhead power transmission line live drainage wire clip in the same tower multi-circuit vertical arrangement mode. Using this tool to deal with the heating defects of live drainage wire clips reduces the investment of operators and tools, reduces the labor intensity and operation risks of operators, improves efficiency, and reduces costs. At the same time, it improves the reliability of power supply and reduces Number of outages.
