Problems solved by technology

[0003] At present, most of the high-strength cables on the market do not meet the technical standards. Due to the high quality of equipment in industries such as ships and ocean engineering, the ropes need to have sufficient tensile strength and strong fire resistance. However, in the existing cables, the fire resistance and strength of the cables cannot be combined because the production requirements are not up to standard or the materials do not meet the requirements.

Embodiment 1

[0038] Embodiment one: if Figure 1 to Figure 6 As shown, a high-performance combined twelve-strand double-braided cable includes a core wire 3 and a cable body 1 sleeved on the core wire 3, and the core wire 3 and the cable body 1 are also provided with a buffer layer 2; the cable The main body 1 includes a plurality of main strands 11 intertwined with each other; the main strand 11 consists of two parallel auxiliary strands 12 twisted from basalt fibers; the auxiliary strands 12 in the main strands are parallel to each other. Basalt fiber only has the characteristics of high strength, high temperature resistance, good durability, corrosion resistance (acid and alkali resistance), no water absorption, good dielectric properties, radiation protection, certain comprehensive properties such as wave absorption and wave transmission, and moderate cost performance. Moreover, the tensile strength (single filament strength) of the basalt fiber is 3000~4800Mpa, so that it has good fir...

Embodiment 2

[0049] Embodiment two: if Figure 7 As shown, the difference from the first embodiment above is that the plurality of auxiliary wire cores 332 are parallel to each other and are wound on the main wire core 331 with the main wire core 331 as the helical axis. In this way, during production, the outer wall of the main wire core 331 is evenly covered with the ultra-high molecular weight polyethylene fiber 32 that constitutes the core wire 3, and then the auxiliary wire core 332 is spirally wound on its outer wall, and then covered on the auxiliary wire core 332. Ultra-high molecular weight polyethylene fiber 32, so that the embedding work of the metal wire 33 in the core wire 3 can be completed, so that it can be wrapped between the auxiliary wire core 332 and the main wire core 331 by winding the auxiliary wire core 332 The ultra-high molecular weight polyethylene fibers 32 are more compact, which contributes to the structural strength of the entire cable.

Embodiment 3

[0050] Embodiment three: as Figure 8 As shown, the difference from the first embodiment above is that the several secondary cores 332 interweave and are wound on the main core 331 with the main core 331 as the helical axis. And the winding way of this kind of metal wire 33, also be first on the outer wall of main wire core 331 evenly cover on the ultra-high molecular weight polyethylene fiber 32 that constitutes core wire 3, then in the secondary wire core 332 that will interweave and twine Sleeve on its outer wall, and then cover the ultra-high molecular weight polyethylene fiber 32 on the auxiliary wire core 332, so that the embedding work of the metal wire 33 in the core wire 3 can be completed, and it can also be wound through the auxiliary wire core 332 In this way, the ultra-high molecular weight polyethylene fiber 32 wrapped between the secondary core 332 and the main core 331 is more compact, which contributes to the structural strength of the entire cable. Moreover,...

Abstract

The invention discloses a high-performance combined twelve-strand double-braided cable which comprises a core wire and a cable body arranged on the core wire in a sleeving mode. A buffer layer is arranged between the core wire and the cable body. The cable body comprises a plurality of main strands twisted together. Each main strand is composed of two parallel auxiliary strands formed by twisting basalt fiber. The auxiliary strands in each main strand are parallel to each other. Basalt fiber has the advantages of being high in strength, resistant to high temperature, high in durability, resistant to corrosion, free of water absorption, good in dielectric property, resistant to radiation, capable of having certain comprehensive performance such as wave absorption and wave permeation, and moderate in cost performance. The tensile strength of basalt fiber is 3000-4800 Mpa, and therefore the strength of the cable is enhanced, and good fireproof performance is achieved. The cable body is formed by weaving the main strands, each main strand is composed of two parallel auxiliary strands formed by twisting basalt fiber, and therefore the cable of the woven structure meets the strength and is high in flexibility, light in weight and small in size.

Description

technical field [0001] The present invention relates to a kind of rope, more specifically, it relates to a high-performance composite twelve-strand double-braided cable and its production method. Background technique [0002] Ropes are widely used in various fields of life. In some industries such as shipping, logistics, and heavy industry, some high-strength ropes are a necessity. [0003] At present, most of the high-strength cables on the market do not meet the technical standards. Due to the high quality of equipment in industries such as ships and ocean engineering, the ropes need to have sufficient tensile strength and strong fire resistance. However, in the existing cables, the production requirements are not up to standard or the materials do not meet the requirements, so that the fire resistance and strength of the cables cannot be combined. Contents of the invention [0004] Aiming at the deficiencies in the prior art, the first object of the present invention i...
