Abstract

The invention provides an automatic locking shockproof hammer, which comprises two hammer heads, a connecting rod, a hanging rod and a clamping member, wherein the clamping member comprises two hinged semicircular tiles, one of the semicircular tiles is fixed on the hanging rod, the edges of the two semicircular tiles are provided with pull wire threading holes respectively, the pull wire threading hole of one of the semicircular tiles is fixedly provided with a fixed pull wire in a threading mode, the inner surfaces of the two semicircular tiles are provided with reverse hanging teeth respectively, the hanging rod is provided with a wire tightener, the wire tightener comprises a rotating shaft arranged on the hanging rod, a ratchet wheel arranged at one end of the rotating shaft, a pawl arranged on the hanging rod above the ratchet wheel and a winding wheel arranged at the other end of the rotating shaft, the winding wheel is wound with a winding rope, one end of the winding rope is fixed on the winding wheel, the other end of the winding rope is provided with a pull ring, and the rotating shat is further provided with a fixing structure used for fixing the other end of the fixed pull wire. The automatic locking shockproof hammer provided by the invention can save time and labor, and the installation work can be completed very safely.

Description

technical field [0001] The invention relates to the field of electric power installation, in particular to an automatic locking anti-vibration hammer. Background technique [0002] Overhead power lines are affected by wind, ice, low temperature and other meteorological conditions, causing the lines to vibrate and dance. The vibration frequency is high and the amplitude is small. The wind vibration causes the overhead wire to be repeatedly bent at the suspension point, causing material fatigue, and finally leading to broken strands and broken wires. The frequency of dancing is very low, but the amplitude is very large, which can easily cause interphase flashover, resulting in serious accidents such as line tripping, power failure or burnt conductors. The anti-vibration hammer is attached to the suspension point of the line tower to absorb or weaken the vibration energy, change the line swing frequency, and prevent the line from vibrating or dancing. The anti-vibration hamme...
