Vibration damper capable of preventing slippage or ponding

Abstract

The invention discloses a vibration damper capable of preventing slippage or ponding in the technical field of vibration dampers. The vibration damper comprises a steel strand and a damper head, wherein the steel strand is connected with the damper head; the bottom of the damper head is fixedly connected with a balance weight screw; a row of balance weights are arranged on the balance weight screw; the end of the balance weight screw is in screw joint with two groups of anti-falling nuts; the end of the steel strand is connected with a sleeve; a fine tuning screw is connected into the sleeve in an inserted manner; a clamping piece is locked on the fine tuning screw through bolts; and a check ring, a spring and a limiting ring are arranged at each of two ends of the clamping piece. The balance weights are additionally arranged on the balance weight screw, the adjustment for the weight of the vibration damper is realized so as to adapt different circuit conditions, the vibration damper is convenient for antiskid clamping fixation through the arrangement of a fixed plate, a mounting clamping plate and an antiskid clamping piece, and ponding is convenient to drain through the arrangement of anti-ponding inclined grooves formed in the mounting clamping plate and the fixed plate.

Description

technical field [0001] The invention relates to the technical field of anti-vibration hammers, in particular to an anti-vibration hammer capable of preventing slippage and water accumulation. Background technique [0002] The overhead power lines are affected by meteorological conditions such as wind, ice, and low temperature, causing the lines to vibrate and dance. The vibration frequency is high and the amplitude is small. The wind vibration causes the overhead line to be repeatedly bent at the suspension point, causing material fatigue, and finally leads to broken strands and broken lines. The frequency of galloping is very low, but the amplitude is very large, which can easily cause phase-to-phase short circuit, resulting in serious accidents such as line tripping, power failure or burning of wires. The anti-vibration hammer is hung at the suspension point of the line tower pole to absorb or weaken the vibration energy, change the swing frequency of the line, and preven...

Problems solved by technology

[0005] The object of the present invention is to provide an anti-vibration hammer capable of preventing slippage and water accumulation, so as to solve the problem that the device proposed in the background technology is prone to slipping when the cable is fixed, and the accumulation of water on the fixing piece for a long time is likely to cause the fixing piece to be damaged. Corrosion, it is not convenient to adjust the hammer head distance according to the inclination angle of the cable
