Description

A kind of compound shuttle car cable

Technical field

The utility model relates to field of cable technology, particularly relates to a kind of compound shuttle car cable.

Background technology

Shuttle car back and forth moves defeated car between coal-face and transport tape, as the shuttle on weaving loom, therefore is called shuttle car.And the cable used that matches with shuttle car is shuttle car cable, occupation mode due to shuttle car make cable often to need on cable hank unwinding and rewinding around, therefore cable uses under needing to be adapted at this operating mode, and long-term unwinding and rewinding around, make cable center stressed comparatively concentrated, easily occur disconnected core phenomenon, in order to address this problem, generally can add root reinforcement material at the central core of cable, improve cable life with this.

But along with shuttle car more and more advanced, the demand that shuttle car is carried except basic electric power, also needs the transmission of signal.Mainly adopt in two ways at present, one arranges a signal cable in addition, also has one to be in shuttle car power cable, arrange several signal cores.

Prior art Problems existing and shortcoming:

(1) adopt the mode that a signal cable is set in addition, need increase electric cable takeup reel.Two cables use on shuttle car, and its stability in use is not high, and general signal core sheath is thin, is easily damaged.The signal cable of independent setting is generally easy is subject to extraneous electromagnetic interference, therefore layer of metal screen is usually provided with outward at holding wire cable core, easily there is fatigue in metal screen layer metallic shield in long-term folding and unfolding winding process, cause the fracture of shielding silk, easily stab holding wire core insulation, causes cable to be scrapped.

(2) have following problem in the mode of the inner signalization core of cable, because signal core is easily subject to the impact of electromagnetic interference, the signal core in shuttle car cable is very easy to be affected by shuttle car cabling power core, affects the normal use of signal core.Because signal core cross section is less, in the long-term folding and unfolding winding process of cable, signal core easily ruptures.

Utility model content

The utility model, in order to solve the problem of prior art, provides a kind of compound shuttle car cable, has long service life, Stability Analysis of Structures, signal core long service life, the advantage that flexibility is good.

The compound shuttle car cable of one described in the utility model, comprise by many different cores and the stranded cable core of a signal cable, be provided with the second high strength aramid fiber rope in the bosom of cable core, centered by the second high strength aramid fiber rope, be provided with three power wire core of squeezing mutually, a ground heart yearn and a signal cable; Filler is provided with at the second high strength aramid fiber rope and the gap between three power wire core, a ground heart yearn and signal cables; Sheath and outer jacket is extruded successively outward, weaving carbon fiber silk between sheath and outer jacket at cable core;

Wherein, described signal cable comprises the first high strength aramid fiber rope at center, the second carbon fiber wire being extruded in the signal core outside the first high strength aramid fiber rope and being extruded in outside signal core.

Further improvement, described power wire core by power wire core conductor, be extruded in second third insulating barrier outside power wire core conductor and the first carbon fiber wire be woven in outside second third insulating barrier is formed.

Further improvement, described signal core is made up of with the holding wire core conductor of high strength aramid yarn and the holding wire core insulation layer be extruded in outside holding wire core conductor center.

Further improvement, described ground heart yearn is made up of ground cored wire conductor and the semi-conductive layer be extruded in outside ground cored wire conductor.

Further improvement, the first described high strength aramid fiber rope cross-sectional area is identical with the cross-sectional area of signal core line.

Compared with prior art, the utility model beneficial effect is:

1, the utility model in order to ensure signal core in shuttle car cable frequent unwinding and rewinding around operating mode, first in conductor, high strength aramid yarn is provided with when signal core copper conductor is stranded, so just strengthen the tensile strength of holding wire core conductor, copper wire is not easily broken, secondly be provided with a high strength aramid fiber rope at holding wire cable core central core, aramid fiber rope is woven by aramid yarn to form, in folding and unfolding winding process, aramid fiber rope mainly stress point, therefore protects holding wire cable core; Because wire size core is easily subject to the electromagnetic interference of power wire core, therefore woven one deck carbon fiber wire outward at holding wire cable core, Main Function has three: 1, plays shielding action, reduces outside electromagnetic interference; 2, because carbon fiber wire has very strong tensile energy, the tensile strength of cable core is increased; 3, carbon fiber wire flexibility is good, does not affect the softness of cable.

2, the power wire core of cable have employed carbon fiber wire as screen, has shielding action on the one hand, and carbon fiber wire has good softness on the other hand, compared with the way of employing metallic shield of the prior art, has better softness.

3, the utility model is provided with a high strength aramid fiber rope at central core, and the main stress point in folding and unfolding winding process concentrates on center, thus protects cable, makes cable have higher useful life.

4, cable cover(ing) structure protects the+structure of screen+protect outward in adopting, and cable core position can firmly be fixed by sheath, therefore adopts this structure to be to ensure the cable construction of cable stable in long-term folding and unfolding winding process.

Fig. 1 is structural representation of the present utility model.

Embodiment

The compound shuttle car cable of one as shown in Figure 1, comprise by many different cores and the stranded cable core of a signal cable, be provided with the second high strength aramid fiber rope 1 in the bosom of cable core, centered by the second high strength aramid fiber rope 1, be provided with three power wire core of squeezing mutually, a ground heart yearn and a signal cable; Filler 2 is provided with at the second high strength aramid fiber rope and the gap between three power wire core, a ground heart yearn and signal cables; Sheath 3 and outer jacket 5 is extruded outward successively, weaving carbon fiber silk 4 between sheath 3 and outer jacket 5 at cable core; Wherein, described signal cable comprises the first high strength aramid fiber rope 6 at center, the second carbon fiber wire 7 being extruded in the signal core outside the first high strength aramid fiber rope 6 and being extruded in outside signal core.

Described power wire core by power wire core conductor 8, be extruded in second third insulating barrier 9 outside power wire core conductor 8 and the first carbon fiber wire 10 be woven in outside second third insulating barrier 9 is formed.

Described signal core is made up of with the holding wire core conductor 12 of high strength aramid yarn 11 and the holding wire core insulation layer 13 be extruded in outside holding wire core conductor 12 center.

Described ground heart yearn is made up of ground cored wire conductor 14 and the semi-conductive layer 15 be extruded in outside ground cored wire conductor 14.

The cross-sectional area of the first described high strength aramid fiber rope 7 is identical with the cross-sectional area of signal core line, makes the structure of signal cable more stable.

The utility model embody rule approach is a lot; the above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvement, these improvement also should be considered as protection range of the present utility model.
