Abstract

The invention relates to a cable core steel wire rope which comprises a cable core, a wrapping layer and a plurality of steel wire rope strands, wherein the cable core comprises a plurality of signal lines and a plurality of filling lines; the plurality of signal lines and the plurality of filling lines are wound into the cable core; the wrapping layer wraps on the outer side of the cable core; the plurality of steel wire rope strands are wound outside the wrapping layer. As the filling lines are arranged among the signal lines, the cable core steel wire rope is not only high in strength, but also good in corrosion resistance and flexibility; furthermore as the wrapping layer is filled between the cable core and the steel wire rope strands, not only is an effective protection function to the signal lines achieved, but also the stretching resistance of the whole steel wire rope is enhanced, the service life is prolonged, and the resistance to corrosion is improved.

Description

Cable core steel wire rope

Technical field

The present invention relates to steel wire rope field, particularly relate to a kind of cable core steel wire rope.

Background technology

Cable core steel wire rope of the prior art does not have good safeguard measure to holding wire, and therefore, the useful life of cable is low, and is easily corroded and gets rusty etc.

Summary of the invention

The object of this invention is to provide a kind of cable core steel wire rope, to solve the problem that holding wire of the prior art is fragile, useful life is short.

For solving the problems of the technologies described above, as one aspect of the present invention, provide a kind of cable core steel wire rope, comprising: cable core, comprise many holding wires and Duo Gen interstitial wire, many holding wires and Duo Gen interstitial wire are wound in cable core; Integument, is coated on the outside of cable core; Multiple strand wires, are wrapped in the outside of integument.

Further, the number of strand wire is 8.

Further, strand wire comprises 19 to 31 steel wires.

Further, strand wire comprises fuse copper wire and Duo Gen zinc-coated wire, and many zinc-coated wires are wrapped in the outside of fuse copper wire.

Further, between fuse copper wire and Duo Gen zinc-coated wire, be filled with grease.

Further, interstitial wire is polyethylene fibre line.

Further, integument is polyethylene fibre.

Further, the number of holding wire and interstitial wire is two.

The present invention is provided with interstitial wire between holding wire, and not only high, the rotproofness of intensity and pliability are also fine; Also between cable core and strand wire, be filled with integument, not only can play effective protective effect to holding wire, and can add the stretching resistance of forcing whole steel wire rope, extended useful life, improved resistance to corrosion.

Accompanying drawing explanation

Fig. 1 has schematically shown schematic cross-section of the present invention.

Reference numeral in figure: 1, holding wire; 2, interstitial wire; 3, integument; 4, strand wire; 5, fuse copper wire; 6, zinc-coated wire.

Embodiment

Below in conjunction with accompanying drawing, embodiments of the invention are elaborated, but the multitude of different ways that the present invention can be defined by the claims and cover is implemented.

Please refer to Fig. 1, the invention provides a kind of cable core steel wire rope, comprising: cable core, comprise many holding wires 1 and Duo Gen interstitial wire 2, many holding wires 1 and Duo Gen interstitial wire 2 are wound in cable core; Integument 3, is coated on the outside of cable core; Multiple strand wires 4, are wrapped in the outside of integument 3.Preferably, the number of holding wire 1 and interstitial wire 2 is two.Preferably, interstitial wire 2 is polyethylene fibre lines.Preferably, integument 3 is polyethylene fibre.

The effect of interstitial wire 2 is to be closely wound around with holding wire 1, plays the object of filling, full circle, makes the geometry of integument 3 of later process more regular.

Holding wire 1 can mainly play the effect that signal transmits.For example, can transmit remote control signal by holding wire 1, as high-lift operation hanging cradle, main frame is at roof, and operator downstairs just can be by the cable core transmission of signal of cable core steel wire rope the inside, with the rise and fall of Long-distance Control hanging basket, also the walking of main control system, the actions such as rotation.For another example, in fishery, also can use the present invention, like this, both can draw, pull article, again can remote transmission pull collection and the Long-distance Control speed etc. of some mechanics parameters of load.

Existing cable core steel wire rope does not have good safeguard measure to holding wire, and therefore the useful life of cable is low.Integument 3 is closely wound around with cable core, and while avoiding steel wire rope to move on spool, directly wearing and tearing are expressed to the problem that holding wire causes holding wire to damage, thereby have extended useful life.Especially, the present invention can be applicable to open air and fishery equipment, with the rust corrosion that prevents that some rugged environments from causing cable wire rope, and by strand wire 4, the holding wire of the inside is played to good protection and antisepsis.

Preferably, the number of strand wire 4 is 8.Preferably, strand wire 4 comprises 19 to 31 steel wires.

Preferably, strand wire 4 comprises fuse copper wire 5 and Duo Gen zinc-coated wire 6, and many zinc-coated wires 6 are wrapped in the outside of fuse copper wire 5.Because skin has in the mill adopted zinc-coated wire 6, it adopts the manufacture of high-intensity thickening hot galvanizing steel to form, thereby has improved greatly the rupture pull force of steel wire rope, can use at rugged environment.Preferably, fuse copper wire 5 is twisted alternately, has improved because of stressed and has occurred that stretching force is less than breakage problem.Further, in manufacturing process, add grease, can make fuse copper wire 5 and outer protective film more fused, improved and done times of fatigue.

Preferably, between fuse copper wire 5 and Duo Gen zinc-coated wire 6, be filled with grease.Between fuse copper wire 5 and Duo Gen zinc-coated wire 6, be full of grease, the one, reduce between fuse copper wire 5 and Duo Gen zinc-coated wire 6 friction between zinc-coated wire 6 and rope sheave groove; Another effect is to prevent getting rusty and corroding of steel wire rope.

The zinc-coated wire 6 that be made up of many high-tensile steel wires hot dips on the surface of strand wire 4 of the present invention is wound around, and its toughness and anti-corrosive properties are all that general steel wire rope is beyond one's reach, and has guaranteed that holding wire reaches certain stability and reliability in Long-distance Control.

The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
