Description

A kind of flexible cable of high-tensile

Technical field

It the utility model is related to a kind of cable, more particularly to a kind of flexible cable of high-tensile.

Background technology

Under the working environment that port machine, mining etc. frequently move, the movements such as cable can run into curling, pull, distort Situation, cable are in stress for a long time, it is desirable to which cable has the pull resistance and high flexibility of higher.The copper conductor of traditional cable Stretch breaking strength is not more than 200 N/mm², this intensity can not meet to be frequently bended completely, pull demand.

In order to solve existing cable when bending, pull, distorting mobile, since long-time is in stress, easily lead The defects of causing cable jacket cracking failure, disconnected core, urgently a kind of tensile strength is high in market, and invulnerability is strong and service life length Cable meets use demand.

Utility model content

The purpose of the utility model is to overcome the defects of the prior art, there is provided a kind of flexible cable of high-tensile, its The tensile strength and wear resistance of cable entirety are improved, but does not influence the pliability of cable, it is ensured that cable can normally be bent Deng operation.

To achieve the above object, the utility model proposes following technical solution：

A kind of flexible cable of high-tensile, including cable core and the sheath that is coated on outside cable core, wherein cable core is by one It is coated with the tension rope of cushion rubber layer, three power wire cores and a wire core composition, and three power wire cores and a ground Tension rope is coated on interior carry out concentric stranding by core, its twisted lay ratio is 5 ~ 14 times, and the tension rope is multistrand rope The high-carbon steel cord that tensile strength is more than 1800N/mm2 is twisted, and the lay pitch between multistrand rope is 5 ~ 9 times of rope footpath, it is single Strand steel wire rope is twisted by steel wire of the complex root diameter no more than 0.5mm, and the lay pitch is no more than 13 times of diamond-mesh, and the sheath includes Sheath, braiding layer and outer jacket.

Preferably, the power wire core includes cable core conductor, the insulating layer being coated on outside cable core conductor and nonmetallic screen Cover layer.

Preferably, the wire core includes cable core conductor and the semi-conductive layer being coated on outside cable core conductor.

Preferably, the cable core conductor is by the equidirectional bundle strand of tinned copper wire, and twisted lay ratio is passed successively from the inside to the outside Subtract, and outermost layer lay ratio is not more than 14 times.

Formed preferably, the braiding layer weaves for Fypro of the tensile strength more than 1500 N/mm2, into one The overall tensile strength of step lifting.

Compared with prior art, the flexible cable for a kind of high-tensile that the utility model discloses, inside increase by one are anti- Drawstring, can improve tensile property during cable is pullled to more than 1800N/mm2, it is contemplated that the addition of steel wire rope can cause cable Reduction of pliability, for this by adjusting the twisted inside and outside lay pitch of steel wire rope, makes its pliability on the premise of tension degree is met It is unaffected, so that whole cable tensile strength and wear resistance get a promotion, so as to extend the use of whole cable Service life.

Brief description of the drawings

Fig. 1 is the schematic diagram of composite cable described in the utility model.

Embodiment

Below in conjunction with the attached drawing of the utility model, the technical solution of the utility model embodiment is carried out clear, complete Description.

As shown in Figure 1, a kind of revealed flexible cable of high-tensile of the utility model, including cable core and it is coated on cable Sheath outside core, wherein cable core are by the tension for being coated with cushion rubber layer 7 rope 6, three power wire cores and a ground wire Core forms, and the sheath includes sheath 8, braiding layer 9 and outer jacket 10.

Particularly, tension rope is coated on interior carry out concentric stranding by three power wire cores and a wire core, it is twisted Lay ratio is 5 ~ 14 times, and the power wire core includes cable core conductor 1, the insulating layer 2 and nonmetallic screen being coated on outside cable core conductor Layer 3 is covered, the wire core includes cable core conductor 4 and the semi-conductive layer 5 being coated on outside cable core conductor, and the tension rope is multiply Steel wire rope is twisted the high-carbon steel cord that tensile strength is more than 1800N/mm2, and the lay pitch between multistrand rope is the 5 ~ 9 of rope footpath Times, single-strand rope is twisted by steel wire of the complex root diameter no more than 0.5mm, and the lay pitch is no more than 13 times of diamond-mesh.

The cable core conductor is by the equidirectional bundle strand of tinned copper wire, and twisted lay ratio successively decreases successively from the inside to the outside, and outermost Layer lay ratio is not more than 14 times；The braiding layer weaves for Fypro of the tensile strength more than 1500 N/mm2 and forms.

The technology contents and technical characteristic of the utility model have revealed that as above, but those skilled in the art still may be used Teaching and announcement that can be based on the utility model and make a variety of replacements and modification without departing substantially from the utility model spirit, therefore, this Utility model protection scope should be not limited to the revealed content of embodiment, and should include the various replacements without departing substantially from the utility model And modification, and covered by present patent application claim.
