Abstract

The utility model discloses a cable for mine conveying machinery. The cable comprises a plurality of groups of conductors. Each group of conductors is composed of a plurality of conductors that are mutually intertwisted. Each conductor is equipped with a polyester rope which is clustered by intertwisted polyester threads. An insulating layer is wrapped outside each entire group of conductors. An elastic rope made from elastic material in an extrusion molding manner is disposed among the plurality of groups of conductors wrapped with the insulating layers. A through hole is arranged in the elastic rope along the center line of the rope. The plurality of groups of conductors are mutually intertwisted to form a cable core. An inner sheathe layer and a reinforcing layer are respectively wrapped outside the cable core. The reinforcing layer is formed by a high-strength nylon banding strip winding internal layer and an aramid fiber braiding external layer. An outer sheath layer is wrapped outside the reinforcing layer. The polyester ropes are arranged inside the conductors, thereby preventing the cable conductive core from fracture. The elastic rope is disposed among the groups of conductors for the purpose of buffering of extraneous extrusion. The reinforcing layer is arranged between the inner sheathe layer and the outer sheathe layer inside the cable, thereby further enhancing the mechanical strength of the cable and effectively prolonging the service life of the cable.

Description

A kind of mine conveying machinery is used cable

Technical field:

This practicality relates to the mining cable field, relates in particular to a kind of mine conveying machinery and uses cable.

Background technology:

It is to be used for mine scraper or the supporting power consumption cable of similar devices that the rubber insulation mining is carried with mechanical cable, needs frequent moving during use, therefore 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 supply 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 mine conveying machinery is extremely abominable with the operational environment of cable; When unwrapping wire that the mining conveying machinery is in operation or take-up; Cable will receive the friction even the obstruction of ore, thereby make cable frequently receive severe friction, punching press and hard intensity pulling force at work and reverse, and the cycle of scrapping is very short; Need to change continually, make the mine production cost higher.

Practical content:

In order to remedy the deficiency of prior art, this practical purpose provides a kind of mine conveying machinery and uses cable, solves the fracture of cable conduction core, the relatively poor problem of whole tensile property, thus prolonged cable useful life.

This practicality technical scheme following:

The mine conveying machinery is used cable; Comprise several conductor groups; Described several conductor groups are made up of the many mutual stranded bunchys of conductor respectively, it is characterized in that: be equipped with the terylene rope of the stranded bunchy of dacron thread in the described many conductors, described several conductor groups are enclosed with insulating barrier outward respectively; Be provided with the elastic threads of elastomeric material extrusion moulding between a plurality of conductor groups of wrap insulate layer; Elastic threads is provided with through hole along centerline direction, the mutual stranded formation cable core of described a plurality of conductor groups, and described cable core is enclosed with inner restrictive coating, reinforced layer outward successively; Described reinforced layer adopts wrapped internal layer of high-strength nylon band and aramid fiber woven outer layer to constitute, and the reinforced layer outside is enclosed with external sheath layer.

Described mine conveying machinery is used cable, it is characterized in that: described insulating layer material is an ethylene-propylene rubber.

Described mine conveying machinery is used cable, it is characterized in that: described inner restrictive coating, external sheath layer, elastic threads process using squash type, material adopts thermoplastic elastomer (TPE).

This practical advantage is:

The utility model simple in structure; In conductor, be provided with the resistance to tension that terylene rope strengthens conductor; Solve the fracture of cable conduction core, be provided with the extraneous extruding of elastic threads buffering between the conductor group, be provided with the mechanical strength that reinforced layer further improves cable between the external sheath layer in the cable; Prolong the useful life of cable effectively, and still kept better elastic and bendability.
