Specific embodiment

The utility model embodiment discloses a kind of Coal Transportation machine cable, to efficiently solve Coal Transportation machine electricity consumption The excessive problem of the diameter of cable.

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Referring to Fig. 1, the cross-sectional structure that Fig. 1 is Coal Transportation machine cable provided by the embodiment of the utility model shows It is intended to.

In a specific embodiment, a kind of Coal Transportation machine cable is present embodiments provided, the specific cable packet Include restrictive coating 9, power wire core, control conductor and wire core 7.

Wherein restrictive coating 9 generally require as outermost protective layer and play the role of dustproof and waterproof, protect as cable Set, specific material can refer to the prior art.In the present embodiment, it is contemplated that in coal mine environment, cable may be by environment In some objects the mechanical woundings such as cut, scrape, pounding, pressing against, grinding.In order to play better protective effect, preferred sheath herein Layer 9 should select high-performance chloroprene melting glue to be kneaded high-performance neoprene restrictive coating restrictive coating 9, to form the anti-height for cutting, grinding Intensity restrictive coating 9.

Wherein power wire core has three, three is separated into, to carry out power transmission.Three power wire cores are leaned on to center Hold together, so as to have contact with each other each other, i.e., any one is in contact with other two, to constitute angular distribution, i.e. three power lines The central axis of core constitutes three angle points of equilateral triangle, and the distance between any two angle point is power wire core radius Twice.

Wherein control wire core is separated into three, and three control conductors of formation are located at the outer of three control conductors Side, three control conductors are respectively positioned on the inside of restrictive coating 9, and as described above, each power wire core is in cylindrical type, three power The medium position of core forms cavity, and between two power wire cores of arbitrary neighborhood, outer concave is formed in off-centered side Slot is respectively formed an outside groove outwardly in the middle part of that is, above-mentioned equilateral triangle.At this point, three control conductors are respectively set In outside groove between each two neighboring power wire core, when diameter is excessive, preferably with corresponding two power wire cores It offsets, so that overall structure is more compact.Control conductor is separated, is independently taken up space to avoid control conductor, so that filling out It fills between each power wire core in cavity.

Its wire core 7, positioned at the middle part of three power wire cores, i.e., the middle part of above-mentioned triangle, and with each power wire core It is in contact and is partially squeezed in recess, to be bonded the outer surface setting of power wire core.By the way that the setting of wire core 7 is dynamic at three The center position of line of force core not only can effectively guarantee that overall structure is more compact, by from center to each power line Core offsets, and combines active force between each power wire core and control conductor to the active force of two neighboring power wire core, So that power wire core surrounding uniform force, avoids power wire core from deforming, and makes overall structure solid firm, lateral pressure resistant ability has The enhancing of effect ground.

Consider that the high current of power wire core transmission can generate certain interference to the signal of control line conductor 4, it is preferably dynamic herein Line of force core includes power line conductor 1 and the power line shielded layer 3 for being wrapped in 1 outside of power line conductor, and control conductor also includes Control line conductor 4 and the control line shielded layer 6 for being wrapped in 4 outside of control line conductor.So that between control conductor and power wire core Formation two-layer screen layer, two-layer screen layer do not prevent the interference between control conductor and power wire core only effectively, can be with Effectively power wire core is prevented to interfere power equipments other in environment, and effectively prevented in environment, other high currents Or electromagnetism interferes control conductor.Wherein power line shielded layer 3 and control line shielded layer 6, specific material and molding side Formula can refer to the prior art, and in order to guarantee shield effectiveness, preferred power line shielded layer 3 and control line shielded layer 6 are excellent herein Choosing is the fibrage shielded layer of insulated metal, i.e., includes band covering and weaving metallic fibers layer, wherein band covering is wrapped in The outside of weaving metallic fibers layer.

It should be noted that should wherein be additionally provided with power line insulation between power line conductor 1 and power line shielded layer 3 Layer 2 should be additionally provided with control line insulating layer 5, wherein to play insulation between control line conductor 4 and control line shielded layer 6 Effect, wherein power line insulating layer 2 and control line insulating layer 5 can refer to the prior art, in order to play preferably absolutely Edge effect, preferred power line insulating layer 2 and control line insulating layer 5 are ethylene-propylene-diene monomer glue-line herein, wherein ethylene-propylene-diene monomer Glue has preferably heat-resisting etc. ageing-resistant performances.

Further, in order to be preferably cinched together to wire core 7, control conductor and power wire core, herein preferably It is additionally provided with semi-conductive cloth tape layer 8, wherein restrictive coating 9 is extruded in the outside of restrictive coating 9, wire core 7, each power wire core and each A control conductor is respectively positioned on 8 inside of semi-conductive cloth tape layer, effect is tightened to have to each core in inside, to guarantee each core It fits closely together.For semiconductive layer of cloth 5 therein, its role is to eliminate between restrictive coating and outer metal screen layer Air gap.No matter how perfect the processing technology of metal screen layer is, operation and bending deformation, the cold and hot effect etc. in construction are more Few that annular flat air gap can be all generated between metal screen layer and restrictive coating, it is very big to the deterioration effect of electric field, leads first Bubble-discharge is caused, until insulation breakdown.

Each embodiment in this specification is described in a progressive manner, the highlights of each of the examples are with other The difference of embodiment, the same or similar parts in each embodiment may refer to each other.

The foregoing description of the disclosed embodiments can be realized professional and technical personnel in the field or using originally practical new Type.Various modifications to these embodiments will be readily apparent to those skilled in the art, and determine herein The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause This, the present invention will not be limited to the embodiments shown herein, and is to fit to and principles disclosed herein The widest scope consistent with features of novelty.
