Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric appliances, in particular to a bidirectional anti-vibration hammer for power lines. Background Art
[0002] Vibration dampers are components designed to reduce wind-induced vibrations in conductors. High-voltage overhead lines are located at high poles with large spans. When wind forces act on the conductors, they vibrate. This creates unfavorable working conditions at the point where the conductors are suspended. Repeated periodic vibrations can cause the conductors to bend and subsequently suffer fatigue damage.
[0003] Currently, there are two main ways to fix the anti-vibration hammer to the conductor: bolt type and pre-twisted type. Among them, the pre-twisted type is more basic and commonly used. The installation of the pre-twisted anti-vibration hammer involves the winding of pre-twisted wires. The number of pre-twisted wires is not less than 3. Workers are required to wind the pre-twisted wires onto the conductor one by one and in circles. This process is time-consuming. In addition, the degree of fit between the pre-twisted wire and the conductor is not high when it is wound on the guide wire, which will cause the anti-vibration hammer to be installed not firmly enough. After a certain period of use, the anti-vibration hammer will slip, weakening the effect of the anti-vibration hammer. Utility Model Content
