Abstract

The utility model discloses a wire rope strenghthened type shuttle car cable, including a cable core, the cable core form by three power core, auxiliary core and the enhancement core transposition that sets up at the cable core center, outmost crowded packet of oversheath at the cable core, it weaves the strengthening rib that reticulates to be equipped with high -strength fiber between cable core and oversheath. The utility model discloses add wire rope respectively and strengthen the core in power core conductor, auxiliary core conductor, directly play the humidification to the conductor, can endure that alternating bending flare -outs and be difficult for splitting. Through carry out the optimal design to conductor transposition structure, synnema, the compound hank of conductor are the transposition of same direction with wire rope promptly, improve its compliance greatly, improve the adaptability of conductor to the special operation requirement of shuttle car.

Description

The reinforced shuttle car cable of a kind of steel wire rope

Technical field

The utility model relates to field of cable technology, particularly relates to the reinforced shuttle car cable of a kind of steel wire rope.

Background technology

Shuttle car cable, in use along with the motion of shuttle car, is in all the time and is wound---under the cycle movement state that stretching---reeling---is stretching more again.Because underworkings is very narrow, cable has the possibility injured by a crashing object by the borehole wall or coal cinder at any time, and be also subject to the restriction of cable hank capacity and shuttle car range ability, the external diameter of cable also must have strict restriction.For these reasons, the useful life of cable is very short, often comes into operation and how long will not break down, cause the shut-down of shuttle car, directly impact is mined and normally the carrying out of driving, and occurs that maximum faults is exactly disconnected core, general disconnected core cable substantially cannot field repair, just need to change cable, but limited because of operational environment, underworkings is narrow, change very difficult, expense people is wasted time and energy, and this is just badly in need of a kind of novel shuttle car cable of research and development, improves the useful life of shuttle car cable.

Utility model content

The utility model, in order to solve the problem of prior art, provides a kind of flexibility better, and tensile strength is better, can tolerate the stretching and reinforced shuttle car cable of steel wire rope that is not easy fracture of alternating bending.

The reinforced shuttle car cable of a kind of steel wire rope described in the utility model, comprises cable core, and described cable core is by three power wire core, an auxiliary core and is arranged on that the strengthening core at cable core center is stranded to be formed; Oversheath is extruded at the outermost layer of cable core; Between cable core and oversheath, be provided with high strength fibre weave webbed reinforcement.

Further improvement, three described power wire core and auxiliary core in up and down between two arranged opposite in cable core.

Further improvement, described power wire core comprises power wire core conductor, extrudes successively outward or wrapped power wire core insulating barrier, power wire core insulation semiconductive shielding layer and power wire core metal screen layer at power wire core conductor; Described power wire core conductor center is also provided with power wire core conductor steel wire rope strengthening core.

Further improvement, described auxiliary core comprises auxiliary core conductor, extrudes successively outward or wrapped auxiliary core insulating barrier, auxiliary core insulation semiconductive shielding layer and auxiliary core metal screen layer at auxiliary core conductor; Described auxiliary core conductor center is also provided with auxiliary core conductor steel wire rope strengthening core.

Further improvement, described strengthening core extrudes layer by steel wire rope and the semiconductive be extruded in outside steel wire rope and forms.

Further improvement, described power wire core conductor steel wire rope strengthening core is identical with the diameter of auxiliary core conductor steel wire rope strengthening core, is all 1/5 of respective conductor diameter.

Further improvement, the diameter of described power wire core conductor steel wire rope strengthening core and auxiliary core conductor steel wire rope strengthening core is the half of cable core core wire rope diameter.

Compared with prior art, the utility model beneficial effect is: the utility model adds steel wire rope strengthening core respectively in power wire core conductor, auxiliary core conductor, directly plays humidification to conductor, can tolerate the stretching and not easy fracture of alternating bending.By being optimized design to conductor strand structure, namely the synnema of conductor, that multiple strand and steel wire rope are same direction is stranded, greatly improves its flexibility, improves the adaptability of conductor to the special instructions for use of shuttle car; The stretching resistance that steel wire rope strengthening core can improve cable is greatly placed in the middle of cable core; Between cable core and sheath, be provided with one deck high strength fibre weave webbed reinforcement, contribute to the intensity strengthening cable, tolerance drags wearing and tearing; The diameter proportion formula of each steel wire rope strengthening core is arranged, the stretching resistance effect of cable is improved further, also makes the rounding property of whole cable better.

Accompanying drawing explanation

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

Embodiment

The reinforced shuttle car cable of a kind of steel wire rope as shown in Figure 1, comprises cable core, and described cable core is by three power wire core of arranged opposite, an auxiliary core and be arranged on that the strengthening core at cable core center is stranded to be formed between two up and down; Oversheath 14 is extruded at the outermost layer of cable core; Between cable core and oversheath, be provided with high strength fibre weave webbed reinforcement 13, contribute to the intensity strengthening cable, tolerance drags wearing and tearing.

Wherein, described power wire core comprises power wire core conductor 2, extrudes successively or wrapped power wire core insulating barrier 3, power wire core insulation semiconductive shielding layer 4 and power wire core metal screen layer 5 outside power wire core conductor 2; Described power wire core conductor 2 center is also provided with power wire core conductor steel wire rope strengthening core 1, and consistent with conductor strand direction, directly plays humidification to conductor, can tolerate the stretching and not easy fracture of alternating bending, greatly improve the stretching resistance of cable.

Wherein, described auxiliary core comprises auxiliary core conductor 9, extrudes successively or wrapped auxiliary core insulating barrier 10, auxiliary core insulation semiconductive shielding layer 11 and auxiliary core metal screen layer 12 outside auxiliary core conductor 9; Described auxiliary core conductor 9 center is also provided with auxiliary core conductor steel wire rope strengthening core 8, and consistent with conductor strand direction, directly plays humidification to conductor, can tolerate the stretching and not easy fracture of alternating bending, greatly improve the stretching resistance of cable.

Wherein, described strengthening core extrudes layer 7 by steel wire rope 6 and the semiconductive be extruded in outside steel wire rope 6 and forms.

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.
