Abstract

The invention relates to an adaptive anti-vibration hammer, which includes an inner cylinder, a tower side handle installed at one end of the inner cylinder, a pull rod arranged inside the inner cylinder, a pull plate of the pull rod installed at the top of the pull rod, and a wire side mounted at the bottom end of the pull rod. The handle, the return spring used to reset the pull rod, and the pull rod stopper arranged on the inner wall of the inner cylinder and used to generate friction with the pull rod pull plate, the pull rod stopper is provided with a stopper spring used to reset the pull rod stopper; The patent of the present invention adopts the method of hammering release to eliminate the vibration of the wire, and controls the critical value of hammering by setting the angle of the friction surface of the tie rod stopper structure, so that the device will not move frequently when the tension of the wire is small.

Description

technical field [0001] The invention relates to an anti-galling (vibration) technology of a transmission wire, in particular to an adaptive anti-vibration hammer. Background technique [0002] Galloping of transmission wires is a ubiquitous natural phenomenon, which brings great damage to the safe operation of transmission lines. Although there are many anti-dancing measures that have played a certain role, galloping of wires occurs from time to time. [0003] The anti-vibration hammer is usually hung on the end of the wire to protect the tension clamp and the wire breakage at the exit of the suspension clamp. It is one of the protective fittings to prevent the wire from vibrating in the breeze. The test found that the anti-vibration hammer cannot meet the vibration suppression requirements of low-frequency vibration (below 30Hz). When the natural vibration frequency of the wire is close to the vibration frequency, the accumulation of low-frequency vibration energy will form...
