Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example 1
Referring to fig. 1-5, for a first embodiment of the present invention, the embodiment provides a high-strength and impact-resistant ultrafine fiber denim rope, which includes a protective sleeve 1 and a rope body 2, a peripheral portion of a cross section of the rope body 2 is formed by weaving a plurality of polymer polyethylene fine fiber rope strands 3 in a staggered manner, a center of a cross section of the rope body 2 is formed by weaving a plurality of high-strength steel wires 4 in a tightly spiral winding manner, a floccule filler 5 is filled between the high-strength steel wires 4 and the polymer polyethylene fine fiber rope strands 3, the outer surface of the rope body 2 is provided with the protective sleeve 1, the protective sleeve 1 is a tubular braided fabric woven by nylon wires or weft yarns, the protective sleeve 1 is sleeved outside the rope body 2 to protect an inner rope body 2 structure, and the protective sleeve 1 is made of an abrasion-resistant material;
as shown in fig. 4 and 5, the high-strength steel wire 4 includes a core wire formed by four ultra-high-strength steel wires 410 of an inner layer and three outer ultra-high-strength steel wires 420 unevenly arranged and twisted around the four core wires of the inner layer, the core wires of the inner layer are arranged in a diamond shape, the twisting direction of the twisting of the outer layer steel wires is S-twisting, and the core wires of the inner layer have no twisting pitch, so as to form a steel cord with an irregular cross section; and the diameter of the inner core wire steel wire is equal to that of the outer core wire steel wire. In a preferred embodiment, the diameter of the inner core wire and the diameter of the outer core wire are 0.25 mm.
The utility model discloses the system of twisting with fingers has been used to the super high strength steel wire of minor diameter, consequently, the lay length when twisting with fingers, all need carry out corresponding redesign to the twisting with fingers etc. of different layer steel cord. The reason why the cord has a large lay length and high productivity but has reduced fatigue resistance is that the larger the lay length, the smaller the degree of torsional deformation of the filaments during twisting of the cord is, and the larger the elastic restoring force thereof is, and if this elastic restoring force is not eliminated, the fatigue resistance of the cord is reduced and the service life is shortened; the steel cord has a small lay length, improved fatigue resistance, and high elongation, but the strength loss due to twisting is large, and the productivity is also reduced. Therefore, the reasonable lay length design according to the steel cord with different strengths and different steel wire diameters is an important performance parameter in the research and development process of the steel cord. In addition, the arrangement structure of the steel cord during twisting, i.e. the cross-sectional shapes of the inner layer cord and the outer layer cord, has an important influence on the glue permeation performance and is also an important consideration. In a preferred embodiment, the lay length of the inner core wire and the outer steel wire is 14.0 mm.
The steel wire structure of the utility model, the core wire steel wire and the outer layer steel wire adopt the ultra-high strength steel wire according to the latest regulation, and the strength is improved by about 20 percent compared with the strength of the steel wire with the common strength with the same diameter; the steel wire diameter is small, and the bending load, the flexibility and the fatigue resistance of the cord are correspondingly improved; the steel wires are twisted in the same direction and are in line contact, the contact area is large, the contact pressure is small, and the abrasion between the steel wires can be effectively reduced. The structure can reduce the thickness of the cord fabric under the condition of ensuring the strength of the tire body, and the manufactured tire has light weight, low heat generation, less oil consumption, and production resources and production cost conservation. The incomplete parcel of three outer steel wires to the heart yearn in middle leaves more clearances, and the infiltration of the rubber of being convenient for is favorable to improving the adhesive force between rubber and the steel cord, avoids moisture infiltration to between the steel wire of steel cord among the adverse circumstances, leads to when the tire is by the inflection repeatedly, the accelerated corrosion problem that the steel cord probably produced.
So greatly increased the life of enlightening nima rope to can conveniently change or restore after 1 wearing and tearing of protective sheath are serious, the maintenance spending of enlightening nima rope that significantly reduces, a enlightening nima rope inside base rope is woven into in a plurality of high strength steel wires of rethread 4 closely winding, makes the utility model discloses the weight that can bear when using is heavier and not fragile, makes the utility model discloses the structure is more firm.
