Special tool for tightening live side bolts by ground potential method

Abstract

The invention discloses a special tool for tightening bolts on the live side by the ground potential method. The combination of an operating rod and a pull rope is used to deal with the defects of the bolts on the live side at the ground potential, so as to improve the defect elimination ability and ensure the safe operation of the line; the operating rod and the pull rope During the use process, one person can complete most of the tightening operations, saving manpower. The invention comprises an operating rod, the operating rod is connected with the fixed arm, the fixed arm assembly head of the fixed arm is connected with the tension arm assembly head of the tension arm, the top end of the fixed arm is extended with a reset arm, and the distal end of the tension arm is connected with the reset arm with a reset tension spring; the far end of the tension arm is also provided with a pull rope ring, and the pull rope ring is connected with a pull rope; the fixed arm ratchet rotating sleeve is rotated and installed on the fixed arm assembly head, and the inner wall of the fixed arm ratchet rotating sleeve is used for In the polygonal structure of the set bolt, the outer surface of the fixed arm ratchet rotating sleeve is the fixed arm ratchet, and the fixed arm ratchet is arranged on the fixed arm assembly head to cooperate with the fixed arm ratchet.

Description

technical field [0001] The invention relates to a tool for tightening live-side bolts, in particular for tightening live-side bolts of overhead transmission lines in substations. Background technique [0002] The area where the applicant of this patent is located is a perennial strong wind in Turpan, and the famous "Thirty Mile Wind Area" and "Hundred Mile Wind Area" are well-known far and wide. The wires, insulators and their connecting hardware of overhead transmission lines swing greatly under the action of strong winds. , Under the impetus of the wind, the bolts of each connecting hardware are easy to loosen. If the processing is not handled in time, it is easy to drop the line and cause a tripping accident. [0003] The loosening of the bolts of the connecting fittings is generally to fasten the bolts or install the bolts, but the looseness of the bolts on the live side should be dealt with by the equipotential operation method or power failure treatment, which is diffi...

[0002] The area where the applicant of this patent is located, the area where Turpan belongs to has strong winds all the year round, and the famous "Thirty Miles Wind Zone" and "Hundred Miles Wind Zone" are well-known far and wide. The conductors, insulators and their connecting fittings of overhead transmission lines swing greatly under the action of strong winds , under the promotion of wind force, the bolts of each connecting fittings are easy to loosen, if it is not handled in time, it is easy to drop the line and cause a trip accident

[0003] The bolt loosening of connecting fittings is usually tightened or added bolts, but the bolt looseness on the live side should be dealt with by the equipotential operation method or power failure, which is difficult and has a high risk factor
