The invention discloses a high-frequency torsional vibration fast energy-absorbing anti-vibration hammer, which belongs to the field of high-voltage wire anti-vibration hammers. It includes a wire clip for fixing on the high-voltage line and a torsional energy-absorbing mechanism installed on the wire clip; the torsional energy-absorbing mechanism adopts the first connecting rod and the second connecting rod to be fixedly installed on the wire clip, and the torsional energy-absorbing mechanism includes Lightweight board, chute, slider, tensile coil spring, unequal arm lever, gear and rack set on the light board along the vertical direction; the upper end of the rack and the short arm end of the unequal arm lever adopt The lever is connected by a spring; the long arm end of the unequal arm lever is equipped with a friction block and a quality B; the friction block can slide along the surface of the light board. The present invention is a multi-free coupling vibration and rapid energy absorption anti-vibration hammer with variable moment of inertia, the higher the torsion frequency, the faster the energy absorption.
Description
technical field [0001] The invention mainly relates to the field of anti-vibration hammers for high-voltage wires, in particular to a high-frequency torsional vibration fast energy-absorbing anti-vibration hammer. Background technique [0002] High-voltage wires are prone to breakage due to vibration, and the service life of high-voltage wires can be improved by installing anti-vibration hammers. This is because the anti-vibration hammer can absorb the vibration energy of the high-voltage wire, and because the anti-vibration hammer always rotates around the high-voltage wire under the action of the wind, the high-voltage wire is most prone to torsional vibration, that is, the rotation of the anti-vibration hammer around the high-voltage wire vibration. The existing anti-vibration hammer is not sensitive to the torsional vibration frequency of the high-voltage line, that is, the energy absorption speed of high and low frequencies does not change much. Therefore, it is very ...
