anti-vibration hammer

Abstract

An anti-vibration hammer for a trolley, which includes a trolley, the anti-vibration hammer is suspended at the bottom of the trolley, and the interior of the trolley includes a first chamber and a second chamber. The second perforation passed through, the first perforation is provided on the side wall of the first chamber, and the pull wire mechanism is fixed in the first chamber, one end of the pulling rope is connected with the pull wire mechanism, and the other end is connected from the inside of the first chamber to the outside. And pass through the first through hole; a wire pulley is provided in the second chamber, and the wire pulley is used to drive the pulley to move on the overhead power transmission wire. The purpose of the present invention is to solve the problem that when the position of the existing anti-vibration hammer needs to be adjusted on the overhead power transmission conductor, the workload is heavy, which is likely to bring threats to human safety, and the adjusted position is likely to have a large error, which cannot meet the requirements. Technical issues concerning the anti-vibration requirements of the actual overhead transmission conductors.

Description

technical field [0001] The invention belongs to the technical field of power line safety protection, in particular to an anti-vibration hammer for a power line. Background technique [0002] Overhead transmission lines are affected by meteorological conditions such as wind, ice, and low temperature in various periods, causing the lines to vibrate and dance. The characteristic of vibration is that the frequency is high and the amplitude is small. The wind vibration causes the overhead transmission wire to be repeatedly bent at the suspension point, causing material fatigue, and finally leads to broken strands and broken wires. In order to reduce the harm caused by these vibrations, the anti-vibration hammer produces a movement opposite to the vibration phase of the overhead transmission wire, so that the vibration of the overhead transmission wire is eliminated or weakened, so as to absorb or weaken the vibration energy, change the line swing frequency, and prevent the line f...
