Description

A kind of new type mining cable

Technical field

The utility model relates to field of cables, particularly relates to a kind of new type mining cable.

Background technology

New type mining cable is commonly referred to as the industrial ground installation of coal mining and underground equipment electric wire cable product, comprising the communication on coal-winning machine, transporter, illumination and signalling arrangement cable, and electric drill cable, cap lamp electric wire and underground moving transformer station feed cable etc.And due to the environment very severe under mine, and need often collide frequently and pull, traditional new type mining cable tensile strength is low, useful life is short, substantially can not meet the condition of modern underground work, and therefore the intensity of new type mining cable is in urgent need to be improved.

Utility model content

For solving the technical problem existed in background technology, the utility model proposes a kind of new type mining cable, effectively can improve the intensity of new type mining cable and the useful life of fail safe and prolongation new type mining cable.

A kind of new type mining cable that the utility model proposes, comprising: at least one cable core, the intermediate jacket be positioned at outside cable core, the oversheath being coated on the armour outside intermediate jacket and being coated on outside armour;

Described cable core comprises conductor, the insulating barrier be coated on outside conductor, the inner sheath that is coated on the screen outside insulating barrier and is coated on outside screen from inside to outside successively.

Preferably, armour comprises inner armor layer and armoured layer, and described inner armor layer is closely entwined by copper strips spiral, and described armoured layer is closely entwined by ribbon spiral, inner armor layer is positioned at armoured layer, and the spiral winding direction of inner armor layer and armoured layer is contrary.

Preferably, conductor comprises multilayer, and from inside to outside every layer form by many tinned copper wire spiral windings.

Preferably, insulating packing is filled with between described cable core and intermediate jacket.

Preferably, described cable core comprises three, and abuts against each other between three cable cores.

In the utility model, the new type mining cable proposed, have employed three layers of sheath double hyer insulation, improves collapse resistance power and the insulation property of new type mining cable, improves the security performance of cable; The inside and outside armour that reverse acting spiral is entwined, not only achieve seamless protection, and because helical steel band and copper strips are along the elasticity of cable axis, improve the tensile strength of cable, in addition because inner armor layer is copper strips so be equivalent to add one deck shielding to cable, enhance the shield effectiveness of cable; Conductor comprises multilayer, and every layer all adopts many tinned copper wire spiral windings to form, because copper helices is along the elasticity of cable axis, so when being subject to axial tension when cable, copper wire is not easily pulled off, and improves the tensile strength of cable, and what adopt due to multilayer copper wire again is warp in different spiral, elasticity is different, so copper wire can not be broken simultaneously; Adopt three cable cores abut against each other, three cable cores can be simplified to the triangular structure with rock-steady structure, add the effect of filler between inner sheath and cable core, can ensure the stability of three cable core relative positions.

Accompanying drawing explanation

Fig. 1 is the structural representation of a kind of new type mining cable that the utility model proposes.

Embodiment

As shown in Figure 1, Fig. 1 is the structural representation of a kind of new type mining cable that the utility model proposes.

With reference to Fig. 1, a kind of new type mining cable that the utility model proposes, comprise: three cable cores, be positioned at the intermediate jacket 3 outside cable core, the oversheath 1 being coated on the armour 2 outside intermediate jacket 3 and being coated on outside armour 2, wherein, armour 2 comprises inner armor layer and armoured layer, described inner armor layer is closely entwined by copper strips spiral, described armoured layer is closely entwined by ribbon spiral, inner armor layer is positioned at armoured layer, the spiral winding direction of inner armor layer and armoured layer is contrary, the effect of seamless protection and reinforcing can not only be played, helical steel band and copper strips have the elasticity along cable axis simultaneously, the tensile strength of cable can be improved, inner armor layer is formed by copper strips spiral winding and also has certain shielding action in addition, insulating packing is filled with between wherein said cable core and intermediate jacket 3, many one decks insulating packing can improve the insulation property of cable, ensure the security performance of cable, wherein said three cable cores each other against, add the effect of filler, the position stability of cable core can be ensured.

Described cable core comprises conductor 5 from inside to outside successively, the insulating barrier 6 be coated on outside conductor 5, the inner sheath 8 that is coated on the screen 7 outside insulating barrier 6 and is coated on outside screen 7, conductor 5 comprises multilayer, and every layer forms by many tinned copper wire spiral windings from inside to outside, the copper wire of spiral winding can not rupture along cable axial tension as spring in elastic limit, improves the tensile strength of cable.

In the present embodiment, have employed three layers of sheath double hyer insulation, improve collapse resistance power and the insulation property of new type mining cable, improve the security performance of cable; The inside and outside armour that reverse acting spiral is entwined, not only achieve seamless protection, and because helical steel band and copper strips are along the elasticity of cable axis, improve the tensile strength of cable, in addition because inner armor layer is copper strips so be equivalent to add one deck shielding to cable, enhance the shield effectiveness of cable; Conductor comprises multilayer, and every layer all adopts many tinned copper wire spiral windings to form, because copper helices is along the elasticity of cable axis, so when being subject to axial tension when cable, copper wire is not easily pulled off, and improves the tensile strength of cable, and what adopt due to multilayer copper wire again is warp in different spiral, elasticity is different, so copper wire can not be broken simultaneously; Adopt three cable cores abut against each other, three cable cores can be simplified to the triangular structure with rock-steady structure, add the effect of filler between inner sheath and cable core, can ensure the stability of three cable core relative positions.

In the utility model, the new type mining cable proposed, can improve the tensile strength of new type mining cable, ensures the security performance of new type mining cable, extends the useful life of cable.

The above; be only the utility model preferably embodiment; but protection range of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to according to the technical solution of the utility model and utility model design thereof and replace or change, all should be encompassed within protection range of the present utility model.
