Abstract

The utility model discloses a mineral electric drill cable which comprises a plurality of cable conductors that are externally attached with heat-resisting layers. The heat-resisting layers can resist high temperature and are made of IE2 type TSE3941 silica gel mixture; the heat-resisting layers and a plurality of strands of heat and fire resisting fiber reinforced ropes form the cable and are twisted into a whole; each heat and fire resisting fiber reinforced rope is externally extruded and covered with an insulating layer made of polyvinyl chloride; a taped covering layer made of a copper wire nylon weaving net is arranged outside the insulating layer, and is externally extruded and covered with an outer sheath made of polyurethane; and the surface of the outer sheath is coated with a fireproof layer formed by curing fire retardant. The mineral electric drill cable has the advantages that the structure is simple, and the cable has the multilayer material covering structure so as to meet the multiple requirements of high temperature resistance, wear resistance and inflaming retarding, so that the performance of the cable is effectively improved.

Description

Mineral electric drill cable

Technical field

The utility model relates to a kind of cable, relates in particular to a kind of mineral electric drill cable.

Background technology

Hole, present many ore deposits electric drilling device requires very high to cable, because some powerful equipment are arranged, the cable heat-resisting ability that needs is very strong, some in addition reached the 300-400 degree, but a lot of cables all do not reach so high requirement, and situation complexity in the hole, ore deposit, wear and tear and the quality pullled cable has proposed very test, what have can reach the performance requirement that high temperature resistant requirement but can not be satisfied wear-resisting grade.

The utility model content

At the deficiencies in the prior art part, the utility model provides a kind of high-temp resistant fire-retarding wear-resistant cable, can effectively solve cable and can not satisfy the problem high temperature resistant, wear-resisting, that obdurability possesses simultaneously.

To achieve these goals, the technical solution adopted in the utility model is: a kind of mineral electric drill cable, comprise several cable conductors, described cable conductor adheres to the refractory layer of being made by high heat-proof IE2 type TSE3941 silica-gel mixture outward, it is stranded in one that refractory layer and multiply heat-proof combustion-resistant fiber are strengthened the rope stranding, the heat-proof combustion-resistant fiber strengthens extruding outside the rope insulating barrier that one deck is made by polyvinyl chloride, it outside insulating barrier the lapping layer that the copper wire nylon mesh grid is made, lapping layer is extruded with the oversheath that one deck polyurethane is made outward, and the oversheath surface coats fire retardant and solidify to form fireprotection layer.

Compared with prior art, advantage of the present utility model is: simple in structure, the multilayer material package structure of cable can satisfy that it is high temperature resistant, wear-resisting, the multiple requesting of obdurability, has effectively improved the performance of cable.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Embodiment: referring to Fig. 1, a kind of mineral electric drill cable, comprise several cable conductors 1, the described cable conductor 1 outer refractory layer of making by high heat-proof IE2 type TSE3941 silica-gel mixture 2 that adheres to, refractory layer 2 is stranded in one with multiply heat-proof combustion-resistant fiber reinforcement rope 3 strandings, the heat-proof combustion-resistant fiber strengthens extruding outside the rope 3 insulating barrier 4 that one deck is made by polyvinyl chloride, it outside insulating barrier 4 lapping layer 5 that the copper wire nylon mesh grid is made, be extruded with the oversheath 6 that one deck polyurethane is made outside the lapping layer 5, oversheath 6 surfaces coat fire retardant and solidify to form fireprotection layer 7.

Refractory layer 2 can tolerate the high temperature of 300-400 degree, prevent that effectively cable is because of the too high softening transform of the excessive temperature of power, it is stranded in one with refractory layer 2 strandings that multiply heat-proof combustion-resistant fiber is strengthened rope 3, not only fire-retardant, also strengthened the toughness of cable, the insulating barrier of making by polyvinyl chloride 4, guarantee the insulation that cable is inside and outside, the lapping layer 5 that the copper wire nylon mesh grid is made has strengthened the pliability of cable, in complex-terrains such as hole, ore deposit, guarantee safety, oversheath 6 and guaranteed the abrasive resistance of cable, the most surperficial fireprotection layer 7 can effectively prevent the damage of outside burning things which may cause a fire disaster to cable.

Claims

1. mineral electric drill cable, comprise several cable conductors (1), it is characterized in that: the outer refractory layer of making by high heat-proof IE2 type TSE3941 silica-gel mixture (2) that adheres to of described cable conductor (1), refractory layer (2) is stranded in one with multiply heat-proof combustion-resistant fiber reinforcement rope (3) stranding, the heat-proof combustion-resistant fiber strengthens extruding outside the rope (3) insulating barrier (4) that one deck is made by polyvinyl chloride, it outside insulating barrier (4) lapping layer (5) that the copper wire nylon mesh grid is made, lapping layer (5) is outer to be extruded with the oversheath (6) that one deck polyurethane is made, and oversheath (6) surface coats fire retardant and solidify to form fireprotection layer (7).
