Description
[technical field]
The utility model relates to field of cable technology, specifically a kind of mine down-hole fireproof cable.
[background technology]
China's coal-mine aboundresources, large coal mine mainly concentrates Xinjiang, Inner Mongol, Liaoning, Shanxi, Shandong coal to be combustibles, autumn and winter season climate drying is easily on fire, winter, outdoor temperature was extremely low, common mining cable has to pass through buried process, guarantee that cable cover(ing) did not ftracture in winter, construction relative complex; The mining cable of China has formed suitable scale through high speed development in a few years, but because production capacity is greater than demand, there is the situation that supply exceed demand, production capacity has substantially exceeded the forecast demand numerical value in this year, electric wire enterprise all faces the problem of product technology content in urgent need to be improved simultaneously, needs to have mining cable that is low temperature resistant, weather-proof, moistureproof, fire performance.
Because existing mine rubber cable quality is heavy, quality is hard, Cable Bending Radius is large, in use the bending radius of electric cable for coal mining machine local is far smaller than the bending radius of the cable that standard specifies, cable long term frequent is subject to the composite action of the two or more stress such as overbending, stretching, add the cross-sectional area of conductor that control conductor cross-sectional area of conductor is far smaller than cable master core, cause the disconnected core of control conductor.
[summary of the invention]
The purpose of this utility model easily ftractures in adverse circumstances to solve existing mining cable thus cause potential safety hazard, and need the defects such as buried installation, provide a kind of and can adapt to mine down-hole adverse circumstances, high temperature resistant and low temperature, moistureproof mine down-hole fireproof cable.
To achieve these goals, design a kind of mine down-hole fireproof cable, comprise conductor, described conductor adopts that some copper wires are stranded to be formed, fire lagging is wrapped up successively outside conductor, waterproof insulating layer and phase-splitting screen, fire proofing material is filled between each conductor after parcel, insulating layer is wrapped up successively again outside interior, flame retardant bed, metal resistance to compression tensile layer and ring protection jacket layer, described insulating layer bonds aluminium foil again after adopting ceramic fiber paper back adhesive glass fabric and forms, play thermal insulation, increase pulling force and waterproof action, described fixture comprises insulator, conduit, fixed cover, be connected and fixed by fixed cover between two conduits, conduit side is provided with insulator and insulation crust.
Described ceramic fiber paper is replaced by ceramic fiber blanket or ceramic fiber cloth or ceramic fibre strip.
Fire lagging is that mica tape more than three layers or three layers is wrapped outside conductor.
Waterproof insulating layer is at the silicone band of outer wrapped more than two layers of fire lagging, plays damp proof insulation effect.
Described fire proofing material is high flame retardant glass fiber or ceramic fibre rope.
Described phase-splitting screen adopts category-B or 5-6 class conductor, uses, prevent electromagnetic interference on coal-winning machine and mobile device.
Described flame retardant bed is ceramic fibre braid over braid or carbon fiber tape, stops outside flame to combustion.
Described metal resistance to compression tensile layer adopts steel band or steel wire, for hanging well cable, playing the effect of resistance to compression pulling force, alleviating the heavy burden of cable from ground to shaft bottom.
Described ring protection jacket layer selects environment friendly silicon glue material.
Described insulation crust is made up of mineral fibres.
Compared with the existing technology, its advantage is the utility model patent: the construction of cable adopts sandwich construction parcel conductor to form, rational in infrastructure, can reach fire prevention, moistureproof effect, safe and reliable, can reach the user demand of the adverse circumstances in borehole cable; Insulating layer wherein after ceramic fiber paper back adhesive glass fabric, bonds aluminium foil again form, refractory temperature is high, thermal insulation is effective, and quality of materials is light, quality is soft, decrease the weight of whole cable and the external diameter of cable, cable radius flexibility makes greatly the easy mounting and installation of cable and bends, convenient transportation; The material that each layer adopts is all ep-type material, and clean environment firendly is nontoxic, meet national environmental protection policy.

[embodiment]
Below in conjunction with accompanying drawing, the utility model is described in further detail, and the structure of this cable and principle are very clearly concerning the people of this specialty.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, after conductor of the present utility model adopts some category-As or category-B conductive copper skein silk to close, around the fire proofing material of more than three layers or three layers outside conductor, fire proofing material is preferably mica tape, as fire lagging; Fire lagging is outer around two-layer above silicone band, as waterproof fireproofing double action, cable insulation is had more safe and reliable guarantee, wrapped or the proof copper-wire braided of waterproof insulating layer external application copper strips, packed layer is that High-flame-retardancfireproof fireproof packing material is preferably ceramic fiber cotton, rope etc., the outer wrapped insulating layer of packed layer, the outer wrapped flame retardant bed of insulating layer, parcel environment friendly silicon plastic boot after flame retardant bed external application metal resistance to compression tensile layer parcel.Cable also comprises fixture, and fixture comprises insulator, conduit, fixed cover, is connected and fixed between two conduits by fixed cover, and conduit side is provided with insulator and insulation crust.This cable can be applicable to mine down-hole and fixes or the occasion such as mobile device, military project are explosion-proof, mine down-hole, as the cable of delivery of electrical energy.
By fireproof cable one end connecting switch cabinet of this patent, the other end is connected to mine down-hole and fixes or mobile device, can carry out electric energy transmitting, plant equipment production work.This patent production technology is simple, and product quality can control, and can not produce the advantage of pollution and people's life security during burning to environment, meet country and propose scientific and technical innovation, protection of the environment, be the invention of great significance that mining cable updates.
Fire-proof and water-proof insulating layer in the utility model after ceramic fiber paper back adhesive glass fabric, bonds aluminium foil again form, as shown in Figure 2, ceramic fiber paper can be replaced by ceramic fiber blanket or ceramic fiber cloth or ceramic fibre strip, after this road processes, the toughness of ceramic fiber paper is strengthened greatly, add the refractory temperature of cable, thermal insulation effect, and because the quality of materials adopted is light, quality is soft, alleviate the weight of whole cable, make the easy mounting and installation of cable and bend, convenient transportation; It is banded that ceramic fiber paper also can be cut into a rule, and ceramic fiber paper is used in the wrapped use of cable outer layer.
