Description

Technical Field

[0001] The utility model relates to the technical field of steel wire ropes, in particular to a steel wire rope for vibration reduction of marine equipment. Background Art

[0002] Marine equipment refers to any movable but non-consumable items used on board except for ship spare parts. Marine equipment mainly includes rudder equipment, anchor equipment, mooring equipment, towing equipment, cargo equipment, life-saving equipment, closing equipment, piping, outfitting, bilge water system, ballast system, daily water system, fire fighting equipment, ventilation, air conditioning and refrigeration equipment, etc. Due to the flexible characteristics of wire ropes and complex working conditions, wire ropes become more sensitive to external interference during operation and are prone to abnormal vibration.

[0003] In the process of moving marine equipment, a steel wire rope for marine equipment vibration reduction is needed. In the prior art, the steel wire rope for marine equipment vibration reduction has a small mass and low damping. Under external excitations such as wind, rain, and vibration, it is very easy to cause wind-induced vibration phenomena such as vortex-induced resonance, wake galloping, and wind-rain vibration. The vibration of the steel wire rope can cause fatigue at the joint position of the end of the cable, causing the cable protective cover to crack, thereby accelerating the corrosion of the steel wire. In addition, during the high-speed winding process of the steel wire rope, the steel wire rope will produce instantaneous impact when passing through the arc area between rope groove layers and the fold line area between circles, causing the steel wire rope to vibrate in two directions at the rope outlet end of the drum. The existence of this vibration affects the dynamic characteristics of the lifting system. In severe cases, it will cause loose rope and rope jumping, resulting in system instability, shortening the service life of the steel wire rope, and cannot meet the use requirements. Therefore, a steel wire rope for marine equipment vibration reduction is proposed to solve the above-mentioned problems. Utility Model Content
