Abstract
The invention provides a multi-layer winding high-performance steel wire rope and a preparation method thereof, and belongs to the technical field of steel wire ropes. The number of multi-layer winding high-performance steel wire rope strands is large, so that the overall flexibility and fatigue resistance of the steel wire rope are improved, in addition, the filling density of the steel wire rope is large, the metal area is increased, and the breaking force is correspondingly improved. A filling layer is arranged, and grease in the filling layer can be dispersed, so that the steel wire rope has excellent wear resistance and corrosion resistance. A protection layer is arranged to effectively relieve pressure received by the steel wire rope, and meanwhile, the protection layer plays a role in protecting all strands contained in the steel wire rope. Meanwhile, according to the preparation method of the multi-layer winding high-performance steel wire rope, residual drawing stress during drawing of a steel wire is reduced, twisting stress during stranding is eliminated, the breaking force is correspondingly improved, deformation uniformity of each strand of the steel wire rope is fully guaranteed, and the non-loosening performance of the steel wire rope is improved, so that the service life of the steel wire rope is prolonged, and the steel wire rope shows an excellent performance in the using process.
Description
technical field [0001] The invention relates to the technical field related to steel wire ropes, in particular to a multi-layer wound high-performance steel wire rope and a preparation method thereof. Background technique [0002] The steel wire rope is a spiral steel wire bundle that twists steel wires that meet the requirements in mechanical properties and geometric dimensions according to certain rules. It is composed of steel wires, rope cores and lubricating grease. Because of its high strength, light weight, stable work, not easy to break suddenly, and reliable work, it is used for lifting, pulling, tensioning and carrying in material handling machinery. However, due to structural design and other reasons, the properties such as wear resistance and breaking tensile strength are insufficient, so its own service life is low, and it is difficult to guarantee it when used. Contents of the invention [0003] In view of the above circumstances, the object of the present i...
