Abstract

The invention relates to a damping spring vibration-proof hammer preventing lead vibration and galloping in a power transmission line. The hammer is characterized in that: the hammer comprises a damping spring vibration damper and a wire clamp; the damping spring vibration damper comprises a cylindrical shell which is provided with a piston rod; an upper end and a lower end of the piston rod are installed with locating plates; springs and damping rubber sleeves are provided between the locating plates; the damping rubber sleeves are sleeved on the springs; In the wire clamp, a wire clamp main body is hinged to an upper end of wire clamp gland; the wire clamp main body and an lower end of the wire clamp gland are fixedly connected with the upper end of the piston rod of the damping spring vibration damper; an inside bottom of the cylindrical shell is provided with a counterweight plate; and a antiskid rubber gasket for clamping a lead is provided between the wire clamp main body and the wire clamp gland of the wire clamp. The damping spring vibration-proof hammer in the invention has the advantages of reasonable composition, good effect of power transmission line lead vibration damping and galloping proof, low cost, convenient installation and replacement, safe and reliable use, long work life, strong adaptability of working environment and the like.

Description

technical field [0001] The invention relates to a shock absorber, in particular to a shock absorber for protecting overhead transmission lines and preventing wire vibration and galloping, more specifically, a damping spring anti-vibration hammer. Background technique [0002] The wires in the transmission line are affected by weather conditions such as wind, ice, and low temperature all the year round, and the wires often experience fatigue vibrations, including: breeze vibration in the vertical direction, sub-gap vibration in the horizontal direction, along-line vibration in the along-line direction, Horizontal torsional dancing, etc. The above-mentioned vibrations cause serious damage to towers, wires, fittings and insulators, causing frequent tripping and power outages of the lines, endangering the safe operation of transmission lines, and causing major economic losses. [0003] At present, in EHV and UHV transmission lines, anti-vibration hammers, damping spacers, doubl...
