Abstract
The production process of rope is characterized by that in order to raise breaking strength of rope said invention adopts the following measures: applying pre-tension in all the procedures of production process so as to make all the strands be uniformly forced; removing primary twist procedure; regulating twist and twist torque; and adding protecting cover (layer) on the external surface of rope to increase its forming property and wear-resistance.
Description
The present invention relates to a kind of production technology of rope, especially the manufacture method of high-performance Cable rope for ship.
Cable rope for ship requires: intensity height, not easy fracture; Diameter is little, and is in light weight, is convenient to operation; Bounce-back property is low during fracture, and processing safety is strong; Tension stress fatigue, counter-bending fatigue behaviour are good, long service life and be difficult for agingly, and in addition, rope also should have good forming property.Wherein, fracture strength is one of most important index, and fracture strength is except that the manufacturing raw material that depends on rope, and the correct arrangement of the manufacturing process of rope also is a most important very important influence factor.The layout of the arranged distribution of monofilament, rope yarn, rope strand, the twist, the lay pitch etc. are to wherein every monofilament stressing influence is huge in the rope manufacture process, fracture strength to the whole-root rope rope influences huge naturally, simultaneously, they can't neglect equally to the tension stress fatigue of rope, counter-bending fatigue and the influence in service life.
The manufacturing technique of rope of the prior art is as follows:
(1) monofilament first twist (twist be 70 to 140 twist with the fingers/m)
(2) (twist is 39～78 to twist with the fingers/m) become rope yarn to the reverse retwist of rope silk of multiply behind above-mentioned technology first twist.
(3) many rope yarns more oppositely retwist (twist is 32～64 to twist with the fingers/m) become the rope yarn.
(4) multilayer rope yarn (being generally 3～4 layers) is through being twisted into rope strand, and its burst lay pitch is (diameter is than xd) 3.3.
(5) the synthetic rope that is woven to of multiply rope strand, its rope lay pitch is 3.3 for (diameter is than XD).
With the rope that above-mentioned technology is made, according to the material difference, fracture strength increases with line density, be directly proportional, but (ultimate strength [KN (g/m)] that every meter every gram rope can bear is generally not high and be definite value, is example with the Dyneema material, and its utilization rate is generally 1.1 ± 0.1 for utilization rate.
The present invention aims to provide a kind of production technology of rope, and it can make the rope of being produced have higher utilization rate.
The present invention is that the adjustment by production technology makes the stressed even as much as possible of each monofilament in the rope, thereby make rope integral body reach maximum tension intensity, increase tension stress fatigue, the counter-bending fatigue of rope simultaneously by the adjustment of the twist in each procedure of production technology, the lay pitch, thus the service life of improving rope.
Concrete technical solution is:
The manufacturing technique of rope of the present invention is:
1, monofilament is made it evenly stressed by tensioner, many are twisted as the rope yarn again, and its twist is 32.3 ± 5% sth. made by twisting/m, to add tension distribution be 0.5～1.5% of every single wire fracture brute force in the power of every monofilament.
2, above-mentioned rope yarn is made it evenly stressed by tensioner, multilayer is twisted into rope strand again, and it is 6～18 that its strand twisted with the fingers (diameter is than xd).
3,, make it evenly stressed by tensioner, and multiply is synthetic is woven to rope (its lay pitch (diameter is than XD) of restricting is 3.8～8, makes rope with above-mentioned rope strand.
Further technical solution is:
The above-mentioned rope of making is set with protective sleeve at its outer surface, or scribbles one deck anti-wear performance better protect layer on its surface.
Above-mentioned technology has following characteristics:
1, pre-tension on the per pass operation, thus make silk, rope yarn, the stressed of rope strand evenly avoid rope when stressed as far as possible, progressively rupture owing to the unbalance stress of monofilament (yarn, thigh), thereby improved the fracture strength of rope integral body.
2, omitted the first twist operation.As everyone knows, twisting technology has destruction to the intensity of rope silk, and the omission of first twist operation has improved the fracture strength of rope.
3, protective sleeve (layer) is difficult for by snag, wearing and tearing rope, thereby has prolonged the service life of rope.
In the manufacture process of rope, should consider outside the ultimate strength and utilization rate of rope, and must consider the forming property of rope that forming property is too poor, and is neither easy to use, again easily snag wearing and tearing.
A large amount of tests show, in above-mentioned operation 2, when the thigh lay pitch (diameter is than xd) 8～16 the time, the existing good forming property of rope can reach bigger utilization rate again.
In above-mentioned operation 3, when the rope lay pitch (diameter is than XD) 4～7 the time, the existing good forming property of restricting can reach bigger utilization rate again.
In addition, interrelated again between burst lay pitch and the rope lay pitch in above-mentioned technology, test data shows, when the ratio of the concrete numerical value of the lay pitch of restricting and the concrete numerical value of the thigh lay pitch was 1: 1.6 ± 0.3, the combination property of rope was better.

Analysis and trial-production rope result according to listed test data in the last table can find:
Be apparent that very that (1) rope that new technology is produced old technology is compared, utilization rate has had surprising raising, and increase rate is 8-60%.
(2) keeping under the constant situation of strand pitch, the strand lay pitch is big more, and utilization rate is high more.
(3) keeping under the constant situation of the rope lay pitch, burst lay pitch is big more, and the rope processability is poor more.
(4) keeping under the constant situation of the rope lay pitch, burst lay pitch was at 6～18 o'clock, and the rope utilization rate is higher, and forming property still can.
(5) keeping under the constant situation of the rope lay pitch, burst lay pitch was at 8～16 o'clock, and the rope utilization rate is higher, and forming property is good.
(6) keeping under the constant situation of burst lay pitch, the big more utilization rate of the rope lay pitch is high more.
(7) keeping under the constant situation of burst lay pitch, the rope lay pitch surpasses 8, and rope is loose, and forming property is poor.
(8) keeping under the constant situation of burst lay pitch, the rope lay pitch is less than 3.8, and the rope utilization rate is too low.
(9) keeping under the constant situation of burst lay pitch, the rope lay pitch is 4～7.5, and the rope utilization rate is higher, and forming property is good.
(10) when the thigh lay pitch be 12 lay pitch utilization rate height when being 5.5～7 of restricting simultaneously, and be shaped.
In fact the ultimate strength of rope is analyzed, we as can be known: (1) per pass twisting plays negative effect to brute force, and its fall is 9～13%.(2) rope obtains utilization rate preferably except need, outside the promptly higher fracture strength, also certain forming property must be arranged, guarantee that rope does not influence use, and do not influence its anti-wear performance, therefore twisting be essential again can not be too much in order to avoid influence its fracture strength.(3) rope for certain raw material, must make each monofilament (rope yarn, rope strand) in the rope evenly stressed obtaining higher fracture strength as far as possible.
The present invention is by each inter process pre-tension, make each monofilament (rope yarn, rope strand) in the rope evenly stressed, thereby make rope obtain fracture strength preferably, by the adjustment of the rope lay pitch, burst lay pitch, make rope when obtaining higher fracture strength, enough forming properties are arranged again; And installing additional of protective sleeve (layer) not only makes forming property good, improved the anti-wear performance of rope again.
