Abstract

The utility model discloses an optical fiber cable used for mining machinery. The cable comprises a plurality of conductor groups, and the plurality of conductor groups are respectively formed by twisting a plurality of conductors, with phosphatized steel wires as centers. Aluminium foil taped coverings and EP rubber insulating layers are respectively wrapped outside the plurality of conductor groups, so as to form insulating wire cores. The insulating wire cores are twisted with each other to form a cable core, with an elastic rope which is extruded by an elastic material as a center. A center of the elastic rope is provided with a fiber bundle which is wrapped with a sleeve. High-carbon fiber tows are disposed in the fiber bundle. An inner sheath layer and a composite protective layer wrap outside the cable core in sequence. High-intensity nylon wrapping tapes are used in the composite protective layer, forming an inner layer. Steel wires wind spirally to form an outer layer. The outer sheath layer is wrapped outside the composite protective layer. The cable is an optical fiber composite cable which has superior functions. The phosphatized steel wires disposed in the conductors are not easy to break. The composite protective layer further improves long-time, stable, and effective operation of the cable under environment of frequent severe friction, stamping and large-intensity tensile forces and torsion.

Description

A kind of mining machinery fiber optic cables

Technical field:

The utility model relates to the mining cable field, relates in particular to a kind of mining machinery fiber optic cables.

Background technology:

It is for mine scraper or the supporting power consumption cable of similar devices that the rubber insulation mining is carried with mechanical cable, needs frequent mobilely during use, so to crooked, wear-resisting, punching press with reverse, especially tensile property is had higher requirement.

With regard to the mining cable product, along with the raising day by day of mining machinery producing capacity and place capacity, the scraper that adopts cable directly to power has obtained a large amount of selecting for use, and therefore, the consumption of the rubber insulation mining cable of the type is also increasing.

Because the operational environment of mining machinery cable is extremely abominable, when the unwrapping wire that the mining conveying machinery is in operation or take-up, cable will be subjected to friction even the obstruction of ore, thereby make cable frequently be subjected to severe friction, punching press and big intensity pulling force at work and reverse, the cycle of scrapping is very short, needs to change continually, in addition, the function singleness of cable can not satisfy multi-functional demand.

The utility model content:

In order to remedy the deficiencies in the prior art, the purpose of this utility model provides a kind of mining machinery fiber optic cables, reasonable in design, and the whole cable tensile property is superior, and photoelectricity is compound, has satisfied actual user demand.

The technical solution of the utility model is as follows:

The mining machinery fiber optic cables; comprise several conductor groups; it is characterized in that: described several conductor groups are made of many conductors mutual stranded bunchy centered by the phosphatization steel wire respectively; described several conductor groups are enclosed with the aluminium foil lapping layer outward respectively; ethylene propylene rubber insulated layer constitutes insulated wire cores; insulated wire cores mutual stranded bunchy centered by the elastic threads of elastomeric material extrusion moulding constitutes cable core; the elastic threads center is provided with the fiber bundle that parcel send sleeve pipe; be provided with high carbon fibre tow in the fiber bundle; described cable core is enclosed with inner restrictive coating outward successively; composite protection layer; described composite protection layer adopts the wrapped formation internal layer of high-strength nylon band and steel wire spiral to twine the formation skin, and the composite protection layer outside is enclosed with external sheath layer.

Described mining machinery fiber optic cables is characterized in that: the skin employing steel wire winding spacing of described composite protection layer is not more than 3.5 times of steel wire diameter.

The utility model has the advantages that:

Novel structure of the present utility model, cable is the optical fiber composite cable, and function is superior, is provided with not easy fracture of phosphatization steel wire in conductor, the composite jacket layer further improves cable under the environment that frequently is subjected to severe friction, punching press and big intensity pulling force and reverses, and long-term stability is effectively worked.
