Problems solved by technology

After the fittings move, they lose the anti-shock ability, causing repeated vibration fatigue damage to the ground wire, resulting in broken strands, broken wires, and collapsed towers. At the same time, the loose fitting body will also wear the ground wire
2. After the fittings move, they loosen and may fall from a high altitude, causing casualties
An energy-saving fitting weighs about 4 kilograms and is generally more than 30 meters above the ground. After moving, it will loosen and fall. Once pedestrians and vehicles pass below, the consequences will be disastrous

Abstract

The invention discloses an overhead ground wire fitting displacement resetting device, which comprises a main frame body, a long rod connected to the front portion of the main frame body, a lower fixing frame fixedly connected to the lower portion of the main frame body, two groove pulley blocks arranged on the same side of the main frame body and a pair of clamping hooks fixed to the front side of the long rod. The device is reasonable in structure, convenient to use, convenient to carry and easy to operate. When the device is used for recovering and resetting a shockproof hammer, the situation that operation cannot be completed due to the fact that the recoverer cannot continue to advance due to overturning is avoided. An operator under the tower can complete the operation project without too much experience. Meanwhile, the installation time of a recoverer locking device is reduced and the working efficiency is improved. Not only the defect elimination time is effectively shortened,but also the labor intensity of high-altitude operation personnel can be reduced. The safety of the operation personnel is improved. The device is low in cost, easy to produce and very suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of distribution network, in particular to a displacement reset device for overhead ground wire fittings. Background technique [0002] The pole position of the high-voltage overhead line is relatively high, and the span is relatively large. When the wire is subjected to wind force, it will vibrate. When the conductor vibrates, the working conditions are the most unfavorable where the conductor is suspended. Due to multiple vibrations, the wire will be fatigued and damaged due to periodic bending. When the span of the overhead line is greater than 120 meters, an anti-vibration hammer is generally used for anti-vibration. The anti-vibration hammer is designed to reduce the vibration of the wire caused by the wind. [0003] On high-voltage overhead lines, a small hammer is often hung on the wires near both sides of the insulator. This small hammer is called an anti-vibration hammer, which is designed to redu...
