Description

Weather-resistant steel wire rope

Technical Field

The utility model relates to a wire rope correlation technique field, concretely relates to weather resistant wire rope.

Background

The steel wire rope is a spiral steel wire bundle formed by twisting steel wires with mechanical property and geometric dimension meeting requirements together according to a certain rule, and consists of the steel wires, a rope core and lubricating grease. The steel wire rope is a spiral rope which is formed by twisting a plurality of layers of steel wires into strands, and then twisting a certain number of strands by taking a rope core as a center. In a material handling machine for lifting, pulling, tensioning and carrying. The steel wire rope has high strength, light dead weight, stable work, difficult sudden whole breakage and reliable work.

Although steel wire ropes have many advantages, along with the development of production, the performance requirements on the steel wire ropes are higher and higher, and from the requirements on the service life and safety of the steel wire ropes, the higher the wear resistance and corrosion resistance of the steel wire ropes are, the better the wear resistance and high temperature resistance, bottom temperature resistance and self-lubricating performance of the conventional steel wire rope structures are not ideal.

Through retrieval, the most common phenomena of corrosion and over-quick aging of the existing steel wire ropes, such as marine operation, high-temperature and low-temperature operation environments and the like, can occur due to different use environments. The existing steel wire rope has the problems of poor high temperature resistance, wear resistance and corrosion resistance, larger self weight, poor flexibility, unstable structure, short service life and the like. The common sealing steel wire rope cannot be lubricated by oiling because the interior of the common sealing steel wire rope is integrally sealed, so that the design that the lubricating property among strands is good and the strands are durable is realized by the internal structure of the rope body, and the protective layers are arranged on the outer portions of the internal strands, so that when the steel wire rope receives a pulling force, the protective layers are not good in mutual extrusion and sliding, and the protective layers are easy to damage. Common designs can be found in chinese patents 201721909792.X, 201820626600.2, 201820125421.0, etc.
