Abstract

The utility model discloses a composite cable used for mine machinery. The composite cable comprises a plurality of conductor groups. The plurality of conductor groups are respectively formed by twisting the plurality of conductors, with a phosphatized steel wire as a center. Aluminium foil taped coverings and EP rubber insulating layers respectively wrap outside the plurality of flexible conductors 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. The center of the elastic rope is provided with a video wire which is wrapped with a silicone rubber insulating layer. An inner sheath layer and a composite protective layer wrap outside the cable core in sequence. High strength nylon wrapping tapes are used in the composite protective layer to form an inner layer and steel wire winding spirally to form an outer layer. An outer sheath layer wraps outside the composite protective layer. The cable is simple in structure, and is a composite cable. The cable has dual purposes. The phosphatized steel wires are disposed in the conductors and are not easy to break, and the composite sheath layer further improves long-term stable and effective operation of the cable under environment of frequent severe friction, pressing, and hard intensity pulling force and torsion.

Description

A kind of mining machinery composite cable

Technical field:

This practicality relates to the mining cable field, relates in particular to a kind of mining machinery composite cable.

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 performance of cable is single, can not satisfy multi-functional demand.

Practical content:

In order to remedy the deficiencies in the prior art, this practical purpose provides a kind of mining machinery composite cable, reasonable in design, and the whole cable tensile property is superior, and a cable is dual-purpose, has satisfied actual user demand.

This practicality technical scheme as follows:

The mining machinery composite cable; 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 video line of parcel silicone rubber insulation layer; 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 composite cable is characterized in that: the skin employing steel wire winding spacing of described composite protection layer is not more than 2.5 times of steel wire diameter.

This practical advantage is:

Of the present utility model simple in structure, cable is composite cable, and a cable is dual-purpose, 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.
