Cable shockproof hammer

Abstract

A cable shockproof hammer comprises a cable installation sleeve arranged on a cable, a heavy hammer balance component and a connecting plate used for connecting the cable installation sleeve and the heavy hammer balance component. The cable installation sleeve comprises a semi-arc bearing plate and a semi-arc gland plate which are hinged to each other, and a hinge shaft is arranged between the semi-arc bearing plate and the semi-arc gland plate. The semi-arc bearing plate and the semi-arc gland plate which are hinged to each other are arranged so that a traction rod at a bottom of the semi-arcgland plate is wound on an inner side of a traction rod clamping plate on the connecting plate, and a traction limiting effect can be achieved. Upwarping and loosening of the semi-arc bearing plate are prevented. A limiting pressing plate is arranged between the two traction rod clamping plates. The traction rod is fixed in the traction rod clamping plate through the limiting pressing plate, thelimiting pressing plate is installed in a bolt screw joint mode and is not under stress in a screw joint direction, a bolt is not easy to loosen, long-time stability can be guaranteed, a maintenance frequency is reduced, a maintenance period is prolonged, and labor intensity of workers is reduced.

Description

technical field [0001] The invention relates to the field of power cables, in particular to a cable anti-vibration hammer. Background technique [0002] The anti-vibration hammer is designed to reduce the vibration of the wire due to wind force. The high-voltage overhead line has a higher pole position and a larger span. When the wire is subjected to wind force, it will vibrate. When the wire vibrates, the work at the wire suspension The conditions are the most unfavorable. Due to multiple vibrations, the conductors 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 to prevent vibration. [0003] When the existing anti-vibration hammers for electric power are installed on the cables, most of them are installed on the power cables by means of bolts, and the bolts are used to fix the two splints. The final bolts are also prone to aging after being exposed to the sun an...

Problems solved by technology

[0003] When the existing anti-vibration hammers for electric power are installed on the cables, most of them are installed on the power cables by means of bolts, and the bolts are used to fix the two splints. After the bolts are exposed to the sun and rain in the later stage, they are also very easy to age, which leads to the sliding of the anti-vibration hammer and the installation is not firm. Regular maintenance is required, which increases the workload of the staff.
