A reset device for anti-vibration hammer of overhead ground wire

Abstract

The invention discloses an overhead ground wire shakeproof hammer resetting device in the technical field of communication. The overhead ground wire shakeproof hammer resetting device comprises a mainrod; a mounting disk is mounted at the top of the main rod; a moving rod is fixedly mounted on the side wall of the main rod; a moving groove is formed at the top of the moving rod; a moving pillar is movably mounted in an inner cavity of the moving groove; a resetting plate is arranged at the top of the moving pillar; and a plurality of groups of springs are arranged in an inner cavity of the mounting disk. According to the invention, by holding a hand-held sleeve with a hand and arranging a moving plate, a wire is inserted between clamping plates; by arrangement of the springs, the wire isclamped; under the action of the resetting plate, a shockproof hammer is blocked; by manually rotating a rotary disc, a No.2 rotating shaft is driven to rotate through the rotary disc; a traction ropeis driven to take up by the No.2 rotating shaft; a direction of the traction rope is changed by a fixed pulley; by matching of the moving groove and the moving pillar, the overhead ground wire shakeproof hammer resetting device is convenient to horizontally pull the resetting plate and move the shakeproof hammer so as to take a resetting effect and solve a problem that due to deflection, certainshakeproof hammers are inconvenient for maintenance personnel to repair.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a reset device for an anti-vibration hammer of an overhead ground wire. Background technique [0002] At present, with the acceleration of the pace of domestic industry, the number of power lines has also increased. Due to the advantages of low cost and strong transmission capacity, overhead transmission lines are widely used and are the main components of my country's power grid. However, the overhead power lines are affected by weather conditions such as wind, ice, and low temperature, which cause the lines to vibrate and dance. The vibration frequency is high and the amplitude is small. The wind vibration causes the overhead line to be repeatedly bent at the suspension point, causing material fatigue, and finally leads to broken strands and broken lines. The frequency of galloping is very low, but the amplitude is very large, which can easily cause phase-to-phase flasho...

Problems solved by technology

[0006] The object of the present invention is to provide a reset device for anti-vibration hammers of overhead ground wires to solve the problem that anti-vibration hammers are installed on overhead ground wires of high-voltage power lines proposed in the background technology. After long-term operation, due to various reasons, some anti-vibration hammers can In the event of displacement, sometimes the displacement is far away from the tower. When the line is live, the operator hangs the flying car to work, and the safety distance from the live wire may be insufficient; or in the case of excessive sag of the overhead ground wire, even if the line is cut off The problem of not being able to carry out flying or hanging ladder operations
