Abstract
The invention discloses a sisal core and a steel wire rope with the same, wherein the sisal core comprises a sisal core body, the sisal core body is formed by twisting 5 strands of outer-layer sisal yarn strands and 1 strand of central sisal yarn strand, the adjacent outer-layer sisal yarn strands are in a line contact state, and the outer-layer sisal yarn strands and the central sisal yarn strand are in a line contact state. Compared with the prior art, the sisal core is formed by twisting 5 outer-layer sisal strands and 1 central sisal strand, the filling coefficient of the cross section is increased, the proportion of the sisal core in the steel wire rope is increased, and therefore the deformation resistance of the steel wire rope is improved.
Description
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.
In a preferred embodiment of the present invention, the outer layer strands are 9 strands.
Compared with the prior art, the sisal core is formed by twisting 5 outer-layer sisal strands and 1 central sisal strand, so that the filling coefficient of the cross section is increased, the proportion of the sisal core in the steel wire rope is increased, and the deformation resistance of the steel wire rope is improved.

Referring to fig. 1 and 2, fig. 1 is a schematic structural view of a sisal core; fig. 2 is a schematic structural view of a steel cord.
In this embodiment, a sisal core comprises a sisal core body, wherein the sisal core body is formed by twisting 5 outer sisal strands 1 and 1 central sisal strand 2 in a wrapping manner, the adjacent outer sisal strands 1 are in a line contact state, and the outer sisal strands 1 and the central sisal strand 2 are in a line contact state.
Specifically, in this embodiment, the 5 outer sisal strands 1 are uniformly distributed around the central sisal strand 2.
Specifically, in this embodiment, the strand diameter of the outer sisal yarn strand 1 is larger than the strand diameter of the central sisal yarn strand 2.
A steel wire rope comprises a rope body, wherein the rope body is formed by twisting 9 strands of outer-layer strands 3 and 1 sisal core 4 in a wrapping and twisting mode, and the sisal core 4 is the sisal core 4.
Specifically, in this embodiment, the outer layer strand 3 is composed of 1 central steel wire 5, 9 inner steel wires 6, and 9 outer steel wires 7.
The sisal core 4 is formed by twisting 5 strands of outer-layer sisal strands 1 and wrapping and twisting 1 strand of central sisal strands 2, so that the filling coefficient of the cross section is increased, the proportion of the sisal core 4 in the steel wire rope is increased, and the deformation resistance of the steel wire rope is improved.
The foregoing embodiments are merely illustrative of the principles and features of this invention, which is not limited to the above-described embodiments, but rather is susceptible to various changes and modifications without departing from the spirit and scope of the invention, which changes and modifications are within the scope of the invention as claimed. The scope of the invention is defined by the appended claims.
