Abstract

The utility model discloses a kind of compound rope, including wire rope core and rope skin, the rope suitcase covers wire rope core, and the wire rope core forms via hook system；More connecting filaments can also be evenly arranged with the implementation of above-mentioned compound rope between wire rope core and rope skin.The advantages of the present invention：It is the structure for improving wire rope core using crocheting wire rope core, the overall structure of rope is set to change, it can be made using various existing rope making materials, rope structure after improvement can increase the elongation of rope, prevent the rope strand of rope is integrally broken suddenly from causing load to suddenly disappear, so as to cause personal damage or property loss.

Description

A kind of compound rope

Technical field

A kind of rope is the utility model is related to, more particularly, to a kind of compound rope.

Background technology

The application of compound rope is quite varied, all sees its trace in the every field of industrial construction, production, such as wherein Steel wire rope due to its intensity is high, from heavy and light, stable working, the unfailing performance that is not easy whole root fracture suddenly provide lifting, lead The effect such as draw, carry, tensing.For rope in the case of with load, its tension force is the important references index of cable mechanics performance, Rope elongation on the one hand can cushion load strength, the elongation of another aspect rope is important warning to upper loading limit and pre- Show；The mechanical property of compound rope depends on the material of wire rope core, the material of structure and skin of restricting and structure and the knot of wire rope core and skin of restricting Structure is closed, and how to be combined for wire rope core and rope skin, has there is correlation technique, such as Chinese patent application at present CN101275367A discloses a kind of wire rope for running wire, it is characterized in that being twisted together more side rope strands in wire rope core periphery, and is restricted in side Resin spacer is inserted between stock, the problem of which solving due to the next short-term of the friction belt between rope strand and wire rope core, but it is right Do not have beneficial effect in the extension property of rope；Chinese patent application CN103572500A discloses a kind of polyether sulfone fiber bag Core rope, its rope strand part for restricting skin is S twist directions, another part is Z twist directions, wire rope core is wrapped in rope skin, also without to rope Extension property be improved；Chinese patent application CN103306148 A disclose a kind of aramid fiber compound rope, and its skin of restricting is The double twist direction braidings of aramid fiber form, and wire rope core is the aggregate of 4 rope bodies, and disposably braiding forms for rope skin and wire rope core, and aramid fiber is fine Dimension solves the problems, such as that rope is fire-retardant, but the rope is generally still common kernmantle, is not had in elongation Improved.

Utility model content

In order to solve the above technical problems, the utility model provides a kind of cored for being capable of effective ropes extension property Rope.

The technical solution of the utility model is to provide a kind of compound rope, including wire rope core and rope skin, and the rope suitcase covers wire rope core, The wire rope core forms via hook system.

More connecting filaments are evenly arranged between the wire rope core and rope skin；The contact for increasing wire rope core between skin of restricting, makes hook The elongation effect of sennit core can be delivered to rope skin, and keep the integraty of rope.

The crocheting of described connecting filament one end is in wire rope core, and other end crocheting is in rope skin.

The connecting filament is helical form, and described spiral one end connects wire rope core crocheting point, other end connecting rope skin establishment point；Spiral shell Rotation shape connecting filament can further buffer external force suffered by rope, and further reducing rope, fracture causes personnel's property damage suddenly.

The rope skin is made up of monofilament or multifilament fiber, and the wire rope core is that multifilament fiber hook system forms.

Either multifilament or connecting filament are terylene, polyamide fibre, acrylic fibers, polypropylene fibre, spandex, polyethylene, polypropylene fibre to the monofilament One or more in dimension.

The advantages of the utility model and beneficial effect：It is the structure for improving wire rope core using crocheting wire rope core, makes the whole of rope Body structure changes, and feeding is simple, can use various existing rope making materials, and the rope structure after improvement can increase rope The elongation of rope, prevent that integrally fracture causes load to suddenly disappear suddenly for the rope strand of rope, so as to cause personal damage or Property loss.

Embodiment

With reference to embodiment, the utility model is described in further detail.

Embodiment 1

The utility model provides a kind of compound rope, including rope skin 2 and wire rope core 1；The wire rope core 1 is raw materials used to answer for polypropylene Silk fiber, rope strand are two strands, are made after crochet hook machine hook, a diameter of 4mm of wire rope core 1；Coated again in 1 outer close weave of wire rope core On made of polyester monofilament fiber restrict skin 2, it is described rope skin 2 used in rope strand be 16 strands.

Embodiment 2

The utility model provides a kind of compound rope, including rope skin 2 and wire rope core 1；The wire rope core 1 is raw materials used to answer for polypropylene Silk fiber, rope strand be two strands, be made after crochet hook machine hook, a diameter of 3mm of wire rope core 1, then on wire rope core 1 select crocheting point for Tie point, the end hook of spiral connecting filament 3 one that polyester fiber is made is set to the tie point of wire rope core 1, or in hook rope making core 1 By the direct hook in the one end of spiral connecting filament 3 on the tie point that wire rope core 1 preselects；16 strands made of polyester monofilament fiber are selected afterwards Stock makes rope skin 2, and when coating kernmantle skin 2, it is right on rope skin 2 that the other end of spiral connecting filament 3 preset on wire rope core is incorporated into The tie point answered.

The implementation of embodiment 2 can also be wire rope core with rope skin simultaneously crocheting be molded, and by the crocheting of spiral connecting filament 3 in Connection is formed between wire rope core and rope skin.

Comparative example

The wire rope core being twisted into polypropylene multifilament fibers, rope strand are two strands, then close weave is coated by washing outside wire rope core Rope skin made of synthetic fibre monfil, rope strand used in the rope skin is 16 strands.

The performance test of embodiment 1,2 is as shown in table 1：

Table 1

As shown in Table 1, for compound rope of the present utility model when reaching corresponding breaking load, elongation is apparently higher than with sth. made by twisting Restrict as the compound rope of wire rope core.

Material, reagent and the experimental facilities that the utility model embodiment is related to, it is to meet rope unless otherwise instructed The commercially available prod in field.
