Tool special for wire releasing during measuring of grounding resistance of electric transmission line pole tower

Abstract

The invention provides a tool special for wire releasing during measuring of grounding resistance of an electric transmission line pole tower. The tool comprises a base, wherein a first hinge mount is mounted on each of the two sides at the front end of the base respectively; a second hinge mount is mounted on each of the two sides at the rear end of the base respectively; the front ends of sliding rails are mounted on the first hinge mounts in a hinged manner; a fixing rod is arranged at the rear ends of the sliding rails; a connecting plate is mounted in the two second hinge mounts in a hinged manner; the connecting plate is hinged to the sliding rails through the fixing rod; a rotating shaft is arranged at the upper end of the connecting plate; a wire coil is arranged at each of the two ends of the rotating shaft; a crank is mounted on the outer side end surface of each wire coil; the lower end of each wire coil is positioned in the corresponding sliding rail and matched with the corresponding sliding rail. The special wire releasing tool has the advantages that as the sliding rails and the connecting plate which are mutually hinged, are arranged on the base, the wire coils can move on the sliding rails and the angle between the wire coils and the base can be adjusted, the take-up and releasing angles of insulated wires on the wire coils can be adjusted conveniently, the insulation connecting wires are taken up and released conveniently and the twisting and binding of the insulation connecting wires can be avoided.

Description

technical field [0001] The invention relates to a wire-laying tool, in particular to a special wire-laying tool for measuring the grounding resistance of a power transmission line tower. Background technique [0002] When measuring the grounding resistance of the tower, it is necessary to fix the wire-laying tool on the tower and make the insulated connecting wire perpendicular to the ground so that the wire can be retracted and released conveniently. Winding and bundling are not only inconvenient to take in and out the wires, but also easily deform and break the insulated connecting wires. Moreover, the damage to the internal metal wires caused by the intertwining and bundling of the insulated connecting wires is not easy to be discovered by the staff in time, which brings great inconvenience to the on-site measurement and affects the measurement quality and work efficiency. During field operations, workers are prone to scratches on the skin of their hands. If they are not...

Western medicine treatment is mainly based on immobilization, partial closure and taking anti-inflammatory and analgesic drugs, but these treatment methods cannot effectively control all the symptoms of acute soft tissue injury, and Western medicine anti-inflammatory and analgesic drugs have relatively large side effects, affecting other organs and organs of the body. normal functioning of the system

Although traditional Chinese medicine also has some externally applied medicines for the treatment of epidermal injuries, the medicines often have problems such as slow onset of action, strong taste, inconvenient preparation and use, ineffective effects, long use time, and unstable curative effect.
