Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of anti-vibration hammer equipment, and in particular relates to an overhead line bolt-type anti-vibration hammer. Background Art
[0002] The span of high-voltage overhead lines is large, and the towers are also high. When the conductors are blown by strong winds, they will vibrate strongly. When the conductors vibrate, the working conditions at the point where the conductors are suspended are the most unfavorable. Long-term and periodic vibrations will cause fatigue damage to the conductors, causing the conductors to break strands and wires. Sometimes strong vibrations can also damage hardware and insulators.
[0003] In order to prevent and reduce the vibration of the wire, a certain number of anti-vibration hammers are generally installed near the wire clamps where the wires are suspended. When the wire vibrates, the anti-vibration hammers also move up and down, generating a force that is not synchronized with or even opposite to the vibration of the wire, which can reduce the amplitude of the wire and even eliminate the vibration of the wire.
[0004] The existing anti-vibration hammer is installed and connected by bolts. However, during long-term use, the bolts are easily caused to fall off due to the vibration of the wire, which reduces the stability of the connection between the anti-vibration hammer and the wire, and then causes the anti-vibration hammer to fall off, affecting the safety of the wire.
