Description

Compound rope of covering
Technical Field
The utility model aims at providing a compound rope of covering belongs to new material technical field.
Background
The rope is a common article for daily life and various industries. Common ropes generally comprise plastic ropes, hemp ropes, nylon ropes, cotton ropes and the like, and the ropes have certain strength and softness, are flexible to use and have wide application.
However, for some special occasions, the rope is required to have higher strength, and common plastic ropes, hemp ropes, nylon ropes, cotton ropes and the like cannot meet the use requirements of the occasions. Some high-end type ropes, such as aramid fiber ropes, UHWHDPE fiber ropes, although having high strength, are expensive and therefore have limited use.
Therefore, it is necessary to invent a core-spun composite rope which has low cost and high strength.
Disclosure of Invention
The utility model is the core-spun composite rope invented for achieving the purpose.
The core-spun composite rope is realized by adopting the following scheme:
a core-spun composite rope is composed of a metal core layer, a polypropylene fiber structural layer, a nylon fiber structural layer and an ultrahigh molecular weight polyethylene fiber outer structural layer; the metal core layer is positioned at the central part of the core-spun composite rope and consists of a stainless steel wire; the polypropylene fiber structure layer is positioned between the metal core layer and the nylon fiber structure layer, and 5 strands of polypropylene fiber ropes are wound on the outer surface of the metal core layer in a clockwise direction at an angle of 45 degrees with the long axis direction of the rope to form an integral structure; the nylon wire structural layer is positioned between the polypropylene wire structural layer and the ultra-high molecular weight polyethylene wire outer structural layer, and is wound on the outer surface of the polypropylene wire structural layer in an anticlockwise direction at an angle of 30 degrees with the long axis direction of the rope to form an integral structure; the outer structure layer of the ultra-high molecular weight polyethylene wire is positioned at the outermost side of the core-spun composite rope, and 20 strands of ultra-high molecular weight polyethylene wire ropes are wound on the outer surface of the nylon wire structure layer in a clockwise direction at an angle of 15 degrees with the long axis direction of the rope to form an integral structure.
The polypropylene silk rope is formed by twisting polypropylene silk.
The nylon cord is formed by twisting nylon yarns.
The ultra-high molecular weight polyethylene silk rope is formed by twisting ultra-high molecular weight polyethylene silk.
The core-spun composite rope has reasonable design, unique shape and good integrity, adopts the high-strength metal core layer and the ultra-high molecular weight polyethylene outer structure layer, ensures the high strength of the rope, and expands the application range of the rope; the light polypropylene fiber structure layer and the nylon fiber structure layer are adopted, so that the cost and the weight of the rope are reduced; in addition, the outer structure layer of the ultra-high molecular weight polyethylene yarn on the outermost side has excellent aging resistance and corrosion resistance, so that the rope can be applied to more occasions.
