Abstract
The invention relates to a method for producing a steel wire rope composite cable. The method is characterized in that a steel wire is compacted wound on outer screw of a cable, wherein the diameter of the steel wire is between 1.5 and 4mm; a plurality of steel wire rope strands are arranged outside the steel wire; the strands of the steel wire rope has a single-strand mode, a multi-strand mode and a single-strand and multi-strand combination mode; when the steel wire rope strand is of single-strand, the strand is set to be 1 to 4 layers, and the lay pitch multiple is between 7.0 and 12, and the lay angle in each layer is the same; when the steel wire rope strand is of multi-strand, the strand is set to be 1 to 2 layers, and the lay pitch multiple is between 6.5 and 9; when the steel wire rope strand is of a single-strand and multi-strand combination mode, the single-strand is set to be 1 to 2 layers, the multi-strand is set to be 1 to 2 layers, and the inner single-strand lay pitch multiple is 7.0 to 12, and the outer multi-strand lay pitch multiple is 6.5 to 9; and the multi-strand steel wire rope strand is of wire contact or a compact strand structure in a wire contact mode. The method has the advantages that a cable for transmitting signals in long-distance is protected inside the steel wire rope, and the comprehensive stress performance of the cable is improved.
Description
Technical field
The present invention relates to inner core is cable or the optical cable that needs protection, and skin is a kind of method of producing the compound cable of steel wire rope of steel wire rope sheath.
Background technology
The production of present conventional steel wire rope, the inside of steel wire rope are fibre core or steel core, in inner support, store oil and the increase stretching resistance of mainly plaing a part of steel wire rope.The protection of cable or optical cable is common to be to use armouring; But tension, anti-pressure ability are very limited, are the stretching resistance that improves cable or optical cable, adopt the mode of plug-in steel wire rope at present; The steel wire rope lodge is at the outer surface of cable; Be actually split with cable, steel wire rope only plays the carrying effect, can not drawn, pressurized, curvedly tear open, reverses simultaneously and play a protective role cable.
Summary of the invention
The purpose of this invention is to provide a kind of method of producing the compound cable of steel wire rope, cable is being drawn, pressurized, curved tearing open, plays a protective role simultaneously when reversing.
For solving the problems of the technologies described above, technical scheme of the present invention is:
A kind of method of producing the compound cable of steel wire rope is characterized in that, puts the multilayer protection at the cable peripheral hardware successively, and its operating procedure is following:
1) the cable external spiral is close around steel wire, steel wire diameter 1.5～4mm;
2) steel wire is provided with composite steel silk rope rope strand outward.
Described steel wire rope rope strand is sub-thread, multiply or sub-thread and multiply combining form.
When described steel wire rope rope strand was sub-thread, rope strand was provided with 1～4 layer, 7.0～12 times of lay pitch multiples, and each layer spiral angle is identical.
When described steel wire rope rope strand was multiply, rope strand was provided with 1～2 layer, 6.5～9 times of lay pitch multiples.
When described steel wire rope rope strand was sub-thread and multiply combining form, the sub-thread rope strand was provided with 1～2 layer, and the multiply rope strand is provided with 1～2 layer, 7.0～12 times of internal layer sub-thread lay pitch multiples, 6.5～9 times of outer multiply lay pitch multiples.
Described multistrand rope rope strand is the compacting thigh structure of line contact or line contact form.
Compared with prior art; The invention has the beneficial effects as follows: the compound cable of steel wire rope of the present invention not only has the carrying effect; And through this structure of steel wire rope; The cable of the long Distance Transmission light or the signal of telecommunication is protected the inside at steel wire rope well, and this steel wire rope both can static load also can move, and had guaranteed the light or the signal of telecommunication reliability and stability in remote transmission.

Embodiment
Be described further below in conjunction with the accompanying drawing specific embodiments of the invention:
See Fig. 1, Fig. 2, Fig. 3, a kind of method of producing the compound cable of steel wire rope is provided with the multilayer protection successively outside cable 1, and its operating procedure is following:
1) cable 1 external spiral is close around steel wire 2, steel wire 2 diameters 1.5～4mm;
2) the steel wire 2 outer composite steel silk rope rope strands that are provided with.
The steel wire rope rope strand is sub-thread, multiply or sub-thread and multiply combining form.When the steel wire rope rope strand was sub-thread, sub-thread rope strand 3 was provided with 1～4 layer, 7.0～12 times of lay pitch multiples, and each layer spiral angle is identical.When the steel wire rope rope strand was multiply, multiply rope strand 4 was provided with 1～2 layer, 6.5～9 times of lay pitch multiples.
When the steel wire rope rope strand was sub-thread and multiply combining form, sub-thread rope strand 3 was provided with 1～2 layer, and multiply rope strand 4 is provided with 1～2 layer, 7.0～12 times of internal layer sub-thread rope strand 3 lay pitch multiples, 6.5～9 times of outer multiply rope strand 4 lay pitch multiples.Multiply rope strand 4 is the compacting thigh structure of line contact or line contact form.
The inner core of the compound cable of steel wire rope adopts cable or optical cable; For cable or optical cable are formed protection, twine layer protective layer steel wire 2 at cable or the outside closely spiral of optical cable simultaneously, steel wire 2 closely contacts with cable 1; Prevent that cable 1 is moving at the inner string of steel wire rope, improve structural stability.
Each item service check of the compound cable of steel wire rope mainly is pulling force, bending, reverse three dissolutions of partnership test and whole rope is broken test, confirms to twist with the fingers system loss coefficient, structural stability and the degree of protection of protective layer steel wire when breaking through testing.
