Abstract

The utility model discloses a novel mine-used movable cable, belonging to the cable technical field. The novel mine-used movable cable comprises a conductor, an insulating layer and a jacket, and is characterized in that a twisting-strengthened steel core is arranged, and the twisting-strengthened steel core is arranged at the center of a cable core cabled by an insulating line core composted of the conductor and the insulating layer. Polythene fillers with the foaming degree being above 80% are arranged in the gap of the cable core, and the jacket made of TPU material is extruded and wrappedon the cable core. The conductor is a twisted copper conductor in accordance with the class 5 twisting structure, the material of the insulating layer is ethylene propylene rubber, and the twisting-strengthened steel core is 1+6 steel wire twisted structure. The cable has simple structure, easy production and manufacture and good service property; in addition, the cable not only has higher tensileintensity, but also has good impact resistance and extrusion resistance and excellent wear-resisting property; the movable cable used under a mine well is wearable, therefore, the service life is long.

Description

The new type mining removal cable

Technical field

The utility model relates to a kind of cable, and particularly a kind of both had than high-tensile, has shock resistance, anti-extrusion ability again, and the structure of the mining removal cable of anti-wear performance excellence, belongs to the cable technology field.

Background technology

When mining removal cable is worked under mine, because the particularity of its environment for use, in use, must be high-frequency mobile and crooked, and frequent the moving of equipment such as coal-cutting machinery can produce excessive pulling force, therefore, causes the wearing and tearing of cable cover(ing) and the fracture of core easily.In addition, the distortion in tunnel, down-hole, landslide and sleeper collapse etc. all can make cable bear mechanical stresses such as big impact and tension force, cause cable to be subjected to damage.The existing common mining removal cable that is made of conductor, insulating barrier and sheath etc. is difficult to satisfy the requirement of using removal cable under the mine.

The utility model content

The purpose of this utility model is exactly the particularity at cable environment for use under mine, provides a kind of and has both had than high-tensile, has shock resistance, anti-extrusion ability again, and the new type mining removal cable of anti-wear performance excellence.

The purpose of this utility model is to realize by the improvement to existing cable, the new type mining removal cable, comprise conductor, insulating barrier and sheath, it is characterized in that being provided with stranded reinforcement steel core, stranded reinforcement steel core is arranged on the cable core center of the insulated wire cores stranding that is made of conductor, insulating barrier, be provided with the polyethylene filler of foam degrees more than 80% in the gap of cable core, extrude the TPU material guards on the cable core.

Described conductor is the twisted copper conductors that meets 5 class lay configuration.Insulating layer material is an ethylene-propylene rubber.Stranded reinforcement steel core is a 1+6 steel wire lay configuration.

The utility model is rational in infrastructure simple, manufactures easily, and serviceability is good, and this cable had both had than high-tensile, had shock resistance, anti-extrusion ability again, the anti-wear performance excellence, and mine is used the requirement of removal cable down.Conductor adopts the high-quality copper material twisted copper conductors that meets 5 class lay configuration, cable center is provided with the stranded reinforcement steel core of the lay configuration of 1+6, make cable under harsh service condition, can bear than strong pulling force and self gravitation, and can not occur rupturing, both guaranteed that cable had better tensile strength, guaranteed also that cable still had flexibility preferably simultaneously, and adapted to frequently and move.Adopt the good ethylene-propylene rubber of electrical insulating property as insulation, this material has elasticity preferably, when cable bears external force, can play good cushioning effect.Filler adopts the high polyethylene of foam degrees (more than the 80%) formula that extrudes to fill, and the packing material of high foaming rate can be realized the function of metal armouring, is equivalent to the effect of air bag, can realize stronger shock resistance, anti-extrusion ability.Compare with common mining removal cable, alleviated the deadweight of cable, reduced manufacturing cost.Adopt the sheath of TPU (polyurethane) as cable, because TPU is wear-resisting macromolecular material, so, by extruding the TPU cable jacket, can guarantee that cable operates under the long-term mobile condition, not frayed, the useful life of prolongation cable.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Among the figure: 1 stranded reinforcement steel core, 2 conductors, 3 insulating barriers, 4 fillers, 5 sheaths.

Embodiment

Conductor 2 adopts high-quality copper material lead, and is designed to 5 class lay configuration, guarantees the flexibility of cable.Extrude the good ethylene propylene rubber insulated layer 3 of electrical insulating property at conductor 2 and constitute insulated wire cores.Ethylene-propylene rubber has elasticity preferably, when cable bears external force, can play good cushioning effect.Stranded reinforcement steel core 1 adopts 1+6 steel wire lay configuration.With three eradication edge core and stranded reinforcement steel core 1 stranded strandings, stranded reinforcement steel core 1 places the center of cable core.In the gap of cable core, squeeze and fill the polyethylene filler 4 of foam degrees more than 80%.The packing material of high foaming rate can be realized the function of metal armouring, is equivalent to the effect of air bag, can realize stronger shock resistance, anti-extrusion ability.Compare with common mining removal cable, alleviated the deadweight of cable, reduced manufacturing cost.Extrude TPU (polyurethane) cable cover(ing) 5 at cable core,, can guarantee that cable operates under the long-term mobile condition because TPU is quite wear-resisting macromolecular material, not frayed.
