Description

A kind of coal mine tensile type cable

Technical field

The utility model relates to field of cable technology, specially a kind of coal mine tensile type cable.

Background technique

Coal mine is the mankind in the region of the mining area exploitation coal resources rich in coal, is generally divided into underground mine and outdoor coal Mine.When coal seam is remote from earth's surface, it is typically chosen to underground and digs tunnel digging coal, this is underground mine.When coal seam is away from earth's surface Distance it is close when, be typically chosen directly removing surface soil layer excavate coal, this is open coal mine.China's overwhelming majority coal mine category In underground mine.Coal mine range includes the very big region of above and below ground and related facility.Coal mine is the mankind in digging rich in having The proportional space excavated when the geological stratification of coal generally includes tunnel, well cave and face etc..It is the exploitation of coal mine It is connected to power supply by cable, power supply is ensured, is one of the important power supply facilities on coal mining ground, still, due to coal mining Environment it is complicated, conventional common wiring cable it is frequent for a long time it is mobile, stretch and torsion after will appear distortion, knotting, The problem of fraying and being broken, cause open circuit, short circuit and sheath rupture etc. phenomena such as, seriously endangered coal miner life peace Entirely.

Utility model content

The purpose of this utility model is to provide a kind of coal mine tensile type cables, to solve to propose in above-mentioned background technique Due to the environment on coal mining ground it is complicated, conventional common wiring cable it is frequent for a long time it is mobile, stretch and torsion after The problem of will appear distortion, knotting, fray and be broken, cause open circuit, short circuit and sheath rupture etc. phenomena such as, seriously endangered coal The problem of life security of miner people.

To achieve the above object, the utility model provides the following technical solutions: a kind of coal mine tensile type cable, including more Stock cable, the outer wall of cable described in multiply are socketed with nanofiber pipe, and the lateral wall of nanofiber pipe described in multiply is socketed There is inner restrictive coating, the front surface of the inner restrictive coating is plugged with silica gel hose, and the outer wall of the inner restrictive coating is socketed with armor, The outer wall of the armor is socketed with external sheath layer, and the armor includes rubber bearing layer, the top of the rubber bearing layer It is covered with strengthening layer, is covered with rubber protective layer at the top of the strengthening layer.

Preferably, mutually suit between nanofiber pipe described in multiple groups.

Preferably, the gap filling between nanofiber pipe described in multiple groups has Kafra fiber silk.

Preferably, the silica gel hose is provided with the protrusion of 1mm at interval of 5mm.

Preferably, the external sheath layer is the electro-insulating rubber layer of 1-5mm thickness.

Compared with prior art, the utility model has the beneficial effects that the utility model increases it by nanofiber pipe Ductility, the inner restrictive coating by being perfused with silica gel hose reinforces the structural strength of cable, strong using steel wire and silica gel particle The rigidity for changing cable, reinforces the tensile strength of cable, effectively avoid cable will appear torsion after movement, stretching and torsion Bent, the problems such as knotting, fray and being broken, the life security of coal miner is ensured.

Detailed description of the invention

FIG. 1 is a schematic structural view of the utility model；

Fig. 2 is the utility model longitdinal cross-section diagram.

In figure: 1 cable, 2 nanofiber pipes, 3 inner restrictive coatings, 4 silica gel hoses, 5 armors, 51 rubber bearing layers, the last 52 Change layer, 53 rubber protective layers, 6 external sheath layers.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

The utility model provides a kind of technical solution referring to FIG. 1-2: a kind of coal mine tensile type cable, including multiply Cable 1, five strands or five strands or more of cable are known as Stranded cable 1, and the outer wall of Stranded cable 1 is socketed with nanofiber pipe 2, receives Rice fiber has superhigh intensity and superpower suppleness, enhances the ductility of cable, the lateral wall of multiply nanofiber pipe 2 is equal It is socketed with inner restrictive coating 3, the front surface of inner restrictive coating 3 is plugged with silica gel hose 4, and silica gel hose 4 strengthens the knot of inner restrictive coating 3 Structure intensity, adequately protects cable, reinforces the structural strength of cable, and the outer wall of inner restrictive coating 3 is socketed with armor 5, armouring The outer wall of layer 5 is socketed with external sheath layer 6, and armor 5 includes rubber bearing layer 51, and the top of rubber bearing layer 51 is covered with reinforcing Layer 52, the top of strengthening layer 52 are covered with rubber protective layer 53, and strengthening layer 52 is steel wire, are filled with silicon in the grid of steel wire Glue particle, steel wire and silica gel particle enhance the rigidity of cable, effectively strengthen the tensile strength of cable.
