Abstract
The utility model discloses a lightweight cable used for mine conveying machinery. The lightweight cable comprises a plurality of conductor groups. The plurality of conductor groups are respectively formed by twisting the plurality of conductors. EP rubber insulating layers respectively wrap outside the plurality of conductor groups 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 formed by a pair of twisted phosphatized steel wires. An expanded plastic layer and a composite protective layer wrap outside the cable core in sequence. An outer sheath layer is wrapped outside the composite protective layer. High carbon fibers and preformed holes are distributed along a ring at interval in the outer sheath layer. The cable is simple in structure. The strengthening core is disposed in a center of the cable core, and high carbon fibers are disposed in the outer sheath layer, so the cable core is not easy to break. The design of the expanded plastic layer and the preformed holes reduces weight of the cable. 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
Technical field:
The utility model relates to the mining cable field, relates in particular to a kind of mine conveying machinery lightweight 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, in addition, the weight of cable is bigger, the laying installation difficulty, the cycle of scrapping is very short, needs to change continually, makes the mine production cost higher.
The utility model content:
In order to remedy the deficiencies in the prior art, the purpose of this utility model provides a kind of mine conveying machinery lightweight cable, reasonable in design, and the whole cable tensile property promotes, and weight is lighter, is convenient to lay.
The technical solution of the utility model is as follows:
Mine conveying machinery lightweight cable; comprise several conductor groups; it is characterized in that: described several conductor groups are made of the many mutual stranded bunchys of conductor respectively; described several conductor groups are enclosed with ethylene propylene rubber insulated layer outward respectively and constitute 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 the foamed plastic layer 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; the composite protection layer outside is enclosed with external sheath layer, is distributed with high carbon fibre tow and preformed hole along annular space in the external sheath layer.
Described mine conveying machinery lightweight cable is characterized in that: the skin employing steel wire winding spacing of described composite protection layer is not more than 3 times of steel wire diameter.
The utility model has the advantages that:
Of the present utility model simple in structure, in being provided with strengthening core, external sheath layer, the cable core center is provided with high carbon fibre tow, and cable core is easy fracture not; The design of foamed plastic layer and preformed hole has reduced cable weight, 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.
