Description

Novel electric traction rope with multilayer structure

Technical Field

The utility model belongs to the technical field of the construction of power line construction is used, concretely relates to novel multilayer structure's electric traction rope.

Background

At present, most of the steel wire ropes are used as traction ropes in the paying-off process of power cables, and the steel wire ropes have many defects such as heavy steel wire ropes, difficulty in carrying and paying-off and large traction force; meanwhile, when the steel wire rope is used for field operation, a large amount of machinery and personnel are needed, the area of damaged crops is large, the strength of the steel wire rope is not high enough, the safety is poor, the steel wire rope is easy to wear and generate barbs, and the safety of operators is threatened; on one hand, the steel wire rope is difficult to preserve and maintain, easy to rust and age and high in use cost, and on the other hand, the steel wire rope has extremely poor insulating property and causes personal casualty accidents in the process of power line construction.

In order to solve the problems of the traditional steel wire rope, people develop a Dyneema (high-performance polyethylene fiber) traction rope which has the advantages of good flexibility, light weight, extremely strong tensile strength, excellent ageing resistance, insulation, wear resistance and the like, and the Dyneema rope is formed by weaving and twisting a plurality of Dyneema ropes and then externally arranging a sheath, thereby solving the problems of the traditional steel wire rope. But present electric power line construction operating mode is more and more complicated, and is also higher and more high to the requirement of electric power haulage rope, especially need be the less better to the structure elongation of electric power haulage rope, and the di niema haulage rope of current structure, because the structural difference of twisting with fingers is compiled to a plurality of di niema ropes, lead to having great difference in the electric power haulage rope structure elongation, can not satisfy the high-efficient construction requirement among the current electric power erects, and this is that present the present needs to solve urgently.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to prior art and the not enough of wherein existence, provide a novel multilayer structure's electric traction rope to solve the problem in the above-mentioned background art.

The utility model adopts the following technical scheme: the utility model provides a novel multilayer structure's electric traction rope, includes first sheath, the sand grip that evenly sets up according to the circumference on the first sheath, be equipped with five outer strands and a central rope strand in the first sheath and weave and form, the periphery of outer strands is equipped with the second sheath, outer strands include core rope, intermediate level strands and outer strands, the core rope is single thin steel wire, the intermediate level strands comprise three di nima fibre and the intermediate level steel wire of establishhing with di nima fibre interval, outer strands comprise twelve dupont silk, the center strands are equipped with the third sheath outward, center strands include central core rope and two layers of strands, center core rope is single thick steel wire, two layers of strands are 9 thin steel wires.

Furthermore, the convex strips are distributed according to the circumference, and the number of the convex strips is 4;

further, the thickness of the first sheath layer is larger than that of the second sheath layer.

Further, the thickness of the third sheath is equal to that of the first sheath.

Further, the diameter ratio of the thick steel wires to the thin steel wires is 2: 1.
