Embodiment 1

[0037] Embodiment 1: as figure 1 and figure 2 As shown, a cable that is easy to identify the twisted strands of the rope core includes an outer cladding and a rope core. The outer cladding is braided by rope strand one 1 and two strands two 4, and the rope core is twisted by rope strand three 2. The formed solid rope, strand one 1, strand two 4 and strand three 2 are formed by merging, twisting or braiding several rope yarns 5, and the rope yarns 5 are filled with water-soluble epoxy resin 3. The rope core and the outer cladding are closely bonded together by water-soluble epoxy resin 3. The color of the two strands 24 is different from that of the strand 1. The two strands 24 are in a circular cross shape on the outer cladding. ; The material of rope yarn 5 is ultra-high molecular weight polyethylene.

[0038] Since the rope core and the outer cladding are tightly bonded together by water-soluble epoxy resin 3 to form a whole, when the rope core is twisted, the torsional for...

Embodiment 2

[0040] Embodiment 2: as figure 1 and figure 2 The shown preparation method of the cable that facilitates the identification of twisted strands of the core comprises the following steps:

[0041] Step 1: prepare the rope core: prepare twelve strands of solid rope with a rope making machine: 1) select the raw material: the material of the rope yarn 5 is ultra-high molecular weight polyethylene; 2) twist: when twisting, the twisting machine drive belt Striving to be consistent in tightness, each rope yarn 5 must be controlled by a tensioner, and the speed and twist are tested regularly, and the twist is determined according to the size of the rope strand; 3) Strand making: The rope yarn 5 is arranged reasonably and evenly on the tension ring of the flange according to layers , the tension is the same, the rotating speed is uniform; the prepared rope strands 32; 4) Rope making: twelve rope strands 32 are controlled by the tensioner, and the tension is constant, of which six rope...

Embodiment 3

[0045] Embodiment 3: as figure 1 and image 3 As shown, a cable that is easy to identify the twisted strands of the rope core includes an outer cladding and a rope core. The outer cladding is braided by a rope strand 1 and two strands 2 4, and the rope core is a plurality of parallel rope yarns 5 passed through The four strands bonded by water-soluble polyurethane resin 6, strand one 1, strand two 4 and strand three 2 are formed by merging, twisting or weaving together several rope yarns 5, and the rope yarns 5 Water-soluble polyurethane resin 6 is filled between them, and the rope core and the outer cladding are tightly bonded together by water-soluble polyurethane resin 6. The colors of the two rope strands 24 are different from those of rope strand 11, and the two strands of rope strand 24 are in the outsourcing The layer is a circular cross pattern; the material of the rope yarn 5 is polyarylate.

[0046] The strands 4 bonded by water-soluble polyurethane resin 6 as the ...

Abstract

The invention discloses a cable with rope core twisted strands convenient to identify and a preparation method and application of the cable, and belongs to the field of ropes or cables. The cable comprises an outer wrapping layer and a rope core; the outer wrapping layer is formed by weaving a first rope strand and two second rope strands; the rope core is a solid rope formed by weaving a third rope strand or a fourth rope strand formed by bonding a plurality of parallel rope yarns through water-soluble resin, and the first rope strand, the second rope strands and the third rope strand are all formed by combining, twisting or weaving a plurality of rope yarns together; water-soluble resin is filled between the rope yarns; the rope core and the outer wrapping layer are tightly bonded together through the water-soluble resin; and the color of the two second rope strands is different from that of the first rope strand, and the two second rope strands are in a circulating cross type on the outer wrapping layer. The cable has the advantage that whether the strands in the cable core are twisted or not can be conveniently recognized, and the prepared cable is high in safety performance, long in service life and high in production efficiency.

Description

technical field [0001] The invention belongs to the field of ropes or cables, and in particular relates to a cable which is easy to identify the twisted strands of the rope core and its preparation method and application. Background technique [0002] With the rapid development of marine industry and petrochemical industry, as a commonly used hoisting and dragging tool, the demand for cables is increasing. Most of the existing ropes are twisted or braided, and the soft ropes are easy to bend and twist in seawater. The rope core structure of existing mooring line has two types of single-core twisted rope and multi-core parallel rope. However, due to the instability of the core structure of the single-core twisted rope, it is easy to cause the torsional conductor to break when the mooring line is under tension. The rope core structure of the multi-core parallel rope is extremely loose, so the outer rope is required to wrap the inner core rope. Traditional ropes and cables a...
