Problems solved by technology

[0003] At present, the ordinary anti-vibration hammers on the market are light in weight. Although they can eliminate the natural vibration of the line and the resonance caused by the wind during use, the hammer body has poor wind resistance. It is prone to wind deflection discharge accidents. When it is swaying with the wire, its own resistance is small. When it is driven by the wire to sway, it cannot achieve the best shockproof effect.
When relying on factors such as increasing the volume or force-bearing area to increase the resistance, it will also bring other problems such as heavy loads, which will directly or indirectly cause damage to the line, and the effect of shockproof protection cannot be achieved or the shock absorption effect is poor, and Existing heavy hammers are prone to oxidation, corrosion, etc. if they are exposed to the outside for a long time

Abstract

The invention discloses a corrosion-resistant shake-proof hammer and a surface treatment technique thereof and relates to the technical field of shake-proof hammers of power transmission equipment. The corrosion-resistant shake-proof hammer is composed of, by mass, 0.35%-0.87% of carbon, 0.75%-2.58% of silicon, 12.25%-15.87% of chromium, 3.6%-5.3% of nickel, 0.8%-1.2% of molybdenum, 5.2%-12.6% of manganese, 0.005%-0.009% of niobium, 2.3%-3.5% of aluminum, 3%-8% of copper and the balance ferrum. The corrosion-resistant shake-proof hammer has the advantages of being large in density and good in shake-proof effect; and by spraying a surface coating on the shake-proof hammer, the corrosion resistance and abrasion resistance of the shake-proof hammer are remarkably improved, and thus the service life of the shake-proof hammer is remarkably prolonged.

Description

technical field [0001] The invention relates to the technical field of anti-vibration hammers for power transmission equipment, in particular to a surface treatment process for corrosion-resistant anti-vibration hammers. Background technique [0002] At present, the quality requirements for all aspects of transmission lines are very high, because the safety of transmission lines is very important, otherwise it will cause great safety hazards. Among them, anti-galling of transmission lines is a problem that has attracted attention in recent years. Galloping refers to the self-excited vibration of the wire with low frequency (0.1Hz-3Hz) and large amplitude (up to 10m or more). Because the vibration frequency is high and the amplitude is small, the wind vibration causes the power cable to be repeatedly bent at the suspension point, causing material fatigue, and finally leads to broken strands and broken wires. The frequency of galloping is very low, but the amplitude is very ...
