Compound rope with eight steel cores

Abstract

The invention discloses a compound rope with eight steel cores. The compound rope comprises a central strand and eight peripheral strands surrounding the central strand, wherein the steel core, which is formed by twisting multiple strands of stainless steel wires, is arranged as the central strand; the peripheral strands are formed by twisting multiple strands of chemical fiber ropes; the eight peripheral strands are mutually weaved and coated on the surface of the central strand; the stainless steel wire twisted layers are coated on the outer layers of the eight peripheral strands; the stainless steel wire twisted layers are formed by twisting stainless steel wires. According to the invention, a method of covering the steel cores with chemical fibers is adopted; the compound rope is characterized by light specific gravity, high breaking force and light weight; two stainless steel wire twisted layers are also covered on the outer layers of the peripheral strands, so that the compound rope is suitable for wearable environment; the inner steel cores can cause the elongation to be only 2%-3%; the safety factor is high and the service life is long; the compound rope has the advantages of high flexibility and corrosion resistance of pure chemical fiber rope and the advantages of corrosion resistance and scraping and breaking resistance of the steel wire rope.

Description

technical field [0001] The invention relates to the field of cables, in particular to an eight-strand steel core composite cable. Background technique [0002] In recent years, most of the mooring ropes in major marine projects use carbon steel wire ropes, but there are also some ships that use various chemical fiber ropes. The disadvantage of using carbon steel wire rope is that it is heavy in proportion, inconvenient to operate, not resistant to corrosion, and has a short service life. The reason is that the steel wire is too thin, once in contact with seawater, the acid, alkali, and humid air in the seawater are easy to oxidize, rust and break. For this reason, we try to take measures to strengthen maintenance such as cleaning and oiling, but the effect is still not satisfactory. Although the use of high-molecular polyethylene fiber ropes and other chemical fiber ropes has the advantages of light specific gravity, convenient operation and corrosion resistance, the disad...

Problems solved by technology

The disadvantage of using carbon steel wire rope is that it has a large proportion, inconvenient operation, no corrosion resistance, and short service life.

The reason is that the steel wire is too thin, once in contact with seawater, the acid, alkali and humid air in the seawater are easy to oxidize, rust and break

For this reason, try to take measures to strengthen maintenance such as cleaning and oiling, but the effect is still not ideal

Although the use of high molecular polyethylene fiber rope and other chemical fiber rope has the advantages of light specific gravity, convenient operation and corrosion resistance, the disadvantage is that it is not wear-resistant and not resistant to cutting

During operation, once the fibers of the chemical fiber rope touch the bollard and the surface of the guide rope hole due to corrosion and not smooth, the fibers are easily cut off. In addition, the chemical fiber fibers are easily melted and broken after contacting and friction with objects, resulting in high temperature and long service life. There are also certain problems
