Technical Field

The invention relates to the technical field of steel wire ropes, in particular to a sisal core and a steel wire rope with the same.

Background

At present, a fiber sisal core commonly used in the steel wire rope industry is generally composed of 3 strands or 4 strands, a gap is formed between the strands, the filling coefficient of a cross section is small, and the density is low. The existing method is to achieve the proportion in the steel wire rope by strand extrusion, but during the extrusion process, strand wires have shearing force on sisal yarns, and the sisal yarns can be damaged. Thus, a solution is urgently needed.

Disclosure of Invention

The present invention is directed to solve the above problems, and an object of the present invention is to provide a sisal core and a steel wire rope having the same.

The purpose of the invention is realized by the following technical scheme:

a sisal hemp core comprises a sisal hemp core body, wherein the sisal hemp core body is formed by twisting 5 outer sisal hemp yarn strands and 1 central sisal hemp yarn strand in a wrapping mode, the adjacent outer sisal hemp yarn strands are in a line contact state, and the outer sisal hemp yarn strands and the central sisal hemp yarn strands are in a line contact state.

As a preferable embodiment of the present invention, the 5 outer sisal strands are uniformly distributed around the central sisal strand.

As a preferable aspect of the present invention, the strand diameter of the outer sisal strands is larger than the strand diameter of the central sisal strands.

A steel wire rope comprises a rope body, wherein the rope body is formed by twisting a plurality of outer layer strands with 1 sisal core, and the sisal core is the sisal core.

In a preferred embodiment of the present invention, the outer layer strand comprises 1 central steel wire, 9 inner steel wires, and 9 outer steel wires.
