Description

A kind of mine cable

Technical field

It the utility model is related to field of cables, more particularly to a kind of mine cable.

Background technology

Mining machinery need to move operation, and the cable as machinery power supply is frequently rubbed be subject to ground ore, extrudes bending And reverse, various failures can occur in a short time, influence cable service life.And mining machinery does not require nothing more than electricity with drag cable Gas excellent performance, will more have the comprehensive performances such as bent, the wear-resistant, tear-proof of soft pliable.

Utility model content

In view of this, it is necessary to provide a kind of soft pliable bent, wear-resistant, tear-proof mine cable, it is above-mentioned to meet Demand.

A kind of mine cable, it includes a core, one layer of outer protective jacket being coated on the outside of the core, and filling Wire sheathing between the outer protective jacket and core.The core includes at least a power core and a control core. The power core with control core respectively include one layer in protective layer, one layer of insulation braiding layer being wrapped in the interior protective layer, And extruding is wrapped in the cable core in the insulation braiding layer.The cable core includes multiple conducting wires, which is twisted to the right, and Conjunction lay ratio is 8-10.The insulation braiding layer is coated on the outside of the cable core.The interior protective layer is arranged on the insulation and compiles The outside of tissue layer.The wire sheathing is formed by metal wire braiding and is wrapped in the outside of the core.The outer protective jacket It is made with interior protective jacket of same material and is arranged on the outside of the wire sheathing.It is the outer protective jacket, metal knitted Layer and inner sheath combine together.

Further, the insulation braiding layer is woven and layer by aramid yarn high density gapless.

Further, the core further includes a wire core.

Further, the wire core is identical with the structure of the power core and control core.

Further, extruded insulation layer or semi-conductive layer.

Further, the multiple conducting wires are made of copper wire, and tin is coated with the copper wire.

Further, the multiple conducting wires are twisted to the right two-by-two first, and then stranded conducting wire twists again together two-by-two again Into a cable core.

Further, the outer protective jacket is made with interior protective jacket of polyurethane termoplastic elastomer.

Further, the wire sheathing is woven and layer by stainless guiding principle silk, and the mesh number of the wire sheathing is 10 mesh.

Compared with prior art, the interior protective layer is directly extruded in after being wrapped in due to cable core extruding in insulation braiding layer In, to fix insulated wire cores, so as to prevent from sliding between cable insulation core, add the resistance to torsion of cable.In addition, inside Increase stainless steel wire braiding layer between oversheath, and interior protective layer is made with outer protective jacket of same material so that prevent outside Outer protective jacket, stainless steel wire and interior protective layer combine together when sheath extrudes, so that it is guaranteed that cable entirety tension, the property of tear-proof It can be improved.

Brief description of the drawings

The embodiment of the utility model is described below in conjunction with attached drawing, wherein：

Fig. 1 is a kind of structure diagram of mine cable provided by the utility model.

Embodiment

Specific embodiment of the utility model is further elaborated below based on attached drawing.It should be appreciated that herein Described specific embodiment is only used as embodiment, is not used to limit the scope of protection of the utility model.

Referring to Fig. 1, it is a kind of structure diagram of mine cable provided by the utility model.The mine cable bag Include a core 10, one layer is coated on the outer protective jacket 20 in the outside of core 10, and be filled in the outer protective jacket 20 with Wire sheathing 30 between core 10.It is envisioned that according to the difference of practical use, the mine cable can also wrap Include other functional layers, such as shielded layer, and using in some special occasions when be arranged on cable two special joint or Plug etc., its technology known by those skilled in the art, no longer describes in detail herein.

The core 10 includes at least a power core 11 and a control core 12.In the present embodiment, the core 10 A wire core 13 is further included, the wire core 13 has identical structure with the power core 11 and control core 12.It is described dynamic Power core, control core and wire core 11,12,13 include protective layer 14 in one layer respectively, and one layer is wrapped in the interior protective layer 14 In insulation braiding layer 15, and extruding is wrapped in cable core 16 in the insulation braiding layer 15.The cable core 16 is by multiple conducting wires It is twisted to the right.Specifically, when making the cable core 16, conducting wire is twisted to the right two-by-two first, then again by this two-by-two Stranded conducting wire is twisted into a cable core again together.The conducting wire can be made of copper wire, and be coated with tin on the copper wire.It is described The twisted lay ratio of cable core 16 is 8-10, i.e. the ratio of pitch length and twisted wire outside diameter, wherein, pitch length is in twisted wire axis The complete spiral spacing of one of a twisted wire on direction.The insulation braiding layer 15 is non-porous braiding layer, it can be by aramid fiber The braiding of yarn high density gapless forms.The insulation braiding layer 15 is wrapped in the outside of the cable core 16 by extruding, so as to To play the role of fixed insulated wire cores, and then prevent from sliding between cable insulation core, add the resistance to torsion of cable.Most The cable core 16 for having wrapped up insulation braiding layer 15 is extruded into the interior protective layer 14 together afterwards.The interior protective layer 14 is by polyurethane warm Thermoplastic elastic is made, i.e., is that the polyurethane with certain fluidity is wrapped in institute by frock extruding in the production process State and be enclosed with the cable core 16 of insulation braiding layer 15, so as to form one in the power core 11, control core 12, wire core 13 Bar.As for the power core 11, the difference of core 12, wire core 13 is controlled, it is the specification of conducting wire each used, quantity, And in outside protective layer 14 color it is different, so as to achieve the purpose that differentiation.

The wire sheathing 30 is woven and layer by stainless guiding principle silk, and the mesh number of the wire sheathing is 10 mesh.It is first The outside of the core 10 is wrapped in, and by the way of extruding.During parcel, can by the way of wrapped, The outside of the core 10 is wrapped in round and round.

The outer protective jacket 10 is also made of polyurethane termoplastic elastomer, it in the production process first has this Certain fluidity, and the polyurethane-coated with certain temperature should have certain temperature in the outside of the wire sheathing 30 Polyurethane can also melt certain thickness interior protective layer 14, be then inserted in mould again, the outer protective jacket 10 is shaped, from And the mine cable is made.And in the preparation process of the outer protective jacket 10, since the interior protective layer 14 is also melted Certain thickness so that interior protective layer 14, wire sheathing 30 and the outer protective jacket 10 combine together, so that it is guaranteed that cable is whole Body tension, the performance of tear-proof are improved.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this The spirit of utility model and interior the made all any modification, equivalent and improvement of principle etc., should be included in the utility model Protection domain within.
