Description

Technical Field

[0001] The utility model relates to the technical field of shockproof hammers, in particular to a pre-twisted shockproof hammer for preventing a power transmission line from falling off. Background Art

[0002] Overhead power lines are affected by meteorological conditions such as wind, ice, and low temperature, causing the lines to vibrate and shake. The vibration frequency is high and the amplitude is small. Wind vibration causes the overhead lines to be repeatedly bent at the suspension point, causing material fatigue, and finally leading to strand and wire breakage accidents. The frequency of the dancing is very low, but the amplitude is very large, which can easily cause interphase flickering, causing serious accidents such as line tripping, power outages, or wire burns. Therefore, when erecting transmission lines, it is necessary to use a shock-absorbing hammer, which can absorb or weaken vibration energy, change the line swing frequency, and prevent the line from vibrating or shaking.

[0003] In the prior art, since the shock-absorbing hammer has a relatively simple structure and poor functionality, it cannot be adjusted and fixed according to wires of different sizes during use, thereby affecting the installation efficiency of the workers, and the unstable fixation of the shock-absorbing hammer will also affect the buffering and shock-absorbing effect. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that when the above-mentioned equipment is in use, the shock-absorbing hammer cannot be quickly and effectively fixed, resulting in poor buffering and shock-absorbing effect during use, and thus a transmission line anti-detachment pre-twisted shock-absorbing hammer is proposed.

[0008] Preferably, the outer wall of the steel strand is movably sleeved with a hammer head, the outer walls of the two hammer heads are each provided with two third thread grooves, the inner walls of the four third thread grooves are each movably inserted with a third threaded rod, and the outer walls of the four third threaded rods are movably connected with an arc block.

[0009] Preferably, a waterproof layer is provided on one side of the outer wall of the wear-resistant layer, a corrosion-resistant layer is provided on one side of the outer wall of the waterproof layer, and an anti-oxidation layer is provided on one side of the outer wall of the corrosion-resistant layer.

[0010] Preferably, the wear-resistant layer is made of rubber or polymer material, and the thickness of the wear-resistant layer is 9-15 mm, and the waterproof layer is woven from polyethylene fibers, and the thickness of the waterproof layer is 1-4 mm.

[0011] Preferably, the corrosion-resistant layer is made of stainless steel material, and the thickness of the corrosion-resistant layer is 2-4 mm, and the anti-oxidation layer is made of aluminum alloy material, and the thickness of the anti-oxidation layer is 2-12 mm.
