Abstract

The utility model discloses a strengthening mining machinery cable, comprising 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 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 strengthening core which is formed by twisting two phosphatized steel wires. 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. The phosphatized steel wires are disposed in the conductors, the strengthening core is disposed on the center of the cable core, and the cable core is not easy to break. 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 reinforced mining machinery cable

Technical field:

This practicality relates to the mining cable field, relates in particular to a kind of reinforced mining machinery 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, need to change continually, make the mine production cost higher.

Practical content:

In order to remedy the deficiencies in the prior art, this practical purpose provides a kind of reinforced mining machinery cable, reasonable in design, the fracture that can solve the cable conduction core, the relatively poor problem of whole tensile property.

This practicality technical scheme as follows:

Reinforced mining machinery 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 strengthening core that two phosphatization steel wire pair twists constitute; 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 reinforced mining machinery cable is characterized in that: the skin employing steel wire winding spacing of described composite protection layer is not more than 2 times of steel wire diameter.

This practical advantage is:

Of the present utility model simple in structure, in conductor, be provided with the phosphatization steel wire, the cable core center is provided with strengthening core, cable core is easy fracture not, and 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.

Fig. 1 is this practical structural representation.

Embodiment:

Referring to Fig. 1:

Reinforced mining machinery cable; comprise several conductor groups; several conductor groups are made of many conductors 1 mutual stranded bunchy centered by phosphatization steel wire 2 respectively; several conductor groups are enclosed with aluminium foil lapping layer 3 outward respectively; ethylene propylene rubber insulated layer 4 constitutes insulated wire cores; insulated wire cores mutual stranded bunchy centered by the elastic threads 5 of elastomeric material extrusion moulding constitutes cable core; elastic threads 5 centers are provided with the strengthening core 6 that two phosphatization steel wire pair twists constitute; cable core is enclosed with inner restrictive coating 7 outward successively; composite protection layer; composite protection layer adopts the wrapped formation internal layer 8 of high-strength nylon band and steel wire spiral to twine formation skin 9, and the composite protection layer outside is enclosed with external sheath layer 10.

The skin 9 employing steel wires winding spacings of composite protection layer are not more than 2 times of steel wire diameter.
