Description

Technical Field

[0001] The utility model relates to the field of shockproof hammers, in particular to a shockproof hammer device. Background Art

[0002] Overhead lines often vibrate or dance due to the influence of wind. In order to reduce the vibration and dancing of overhead lines, shock-absorbing hammers are generally hung at the suspension points of overhead lines (the suspension points are mostly close to fixed equipment such as insulator strings, that is, close to the end of the overhead lines). Shock-absorbing hammers are a kind of hammer installed on high-voltage overhead lines. Both ends of the shock-absorbing hammer are provided with hammer bodies of the same size. The purpose is to reduce the vibration of high-voltage overhead lines due to wind force, avoid flipping or bending of the wires, and then fatigue damage.

[0003] After massive searches, it was found that the Chinese patent with the prior art publication number CN209626911U disclosed a shockproof hammer anti-dislocation stable connection device. The patent sets two groups of shockproof hammers of the same size and connects them with limiters, so that the shockproof hammers at both ends of the limiters can also maintain balance when installed on the high-voltage overhead line to avoid one heavy and one light. At the same time, it can prevent two adjacent high-voltage overhead lines from colliding with each other under the action of wind, resulting in the dislocation phenomenon of one of them being placed on the other high-voltage overhead line. However, in this patent, since the hammer body is fixed to the line through a mounting ring and bolts, and the bolts may become loose due to the low temperature in winter, causing the hammer body to fall from the line, affecting the use of the hammer body by the staff. Therefore, based on the above search and combined with the prior art, the utility model proposes a shockproof hammer device to solve the above problems. Utility Model Content
