Abstract

The invention relates to a production method of a high-tenacity fiber pulling rope. The high-tenacity fiber pulling rope is prepared through nine steps including material selection, wire doubling, wire twisting, heat setting, rope core formation, connecting buckle formation, double-sheath formation, coating and injection molding. The production method has the advantages as follows: with the adoption of the production method, the tensile strength of the rope is enhanced, the service life is prolonged, and the rope has the characteristics of lightness, softness and good insulating property.

Description

technical field [0001] The invention relates to the technical field of electric traction ropes, in particular to a production method of a strong wire traction rope. Background technique [0002] At present, in the erection and maintenance of high-voltage lines in the power system, traction ropes are required to drag and erect high-voltage cables to high-altitude towers. The traditional traction rope uses a steel wire rope based on metal materials. Because the steel wire rope is relatively heavy and conductive, the requirements for construction work are relatively high, especially when the surrounding lines are live. Maintenance and installation cannot be carried out, and the use is greatly affected. limitation. Organic polymer traction ropes made of organic polymer materials such as high-strength polypropylene and ultra-high molecular weight polyethylene have high insulation performance, light weight, and strong flexibility, and are widely used. But it still has certain sh...
