Description
Technical field
The present invention relates to a kind of cable, the cable of a kind of stretching resistance being used primarily on mining heavy duty power shovel development machine.
Background technology
Mining heavy duty power shovel development machine feed cable cable random group equipment at work runs, and cable is dragged, draws, drags, rolls over, and the power wire core of cable, wire core are easily pulled, broken, and restrictive coating is easily hindered, easily torn.
Summary of the invention
For solving above-mentioned technical problem, the present invention provides the cable of a kind of stretching resistance.
The present invention is achieved through the following technical solutions: the cable of a kind of stretching resistance, power wire core, earthing detection line and the wire core twisted including bundle；Described power wire core periphery extrudes EPDM insulating cement, and described EPDM insulating cement periphery is woven with resistant fiber pulling woven layer, and resistant fiber pulling woven layer extrudes fluoroplastics on periphery；Described fluoroplastics periphery is provided with screen layer；Described power wire core, gap between earthing detection line and wire core are filled with latex bonded fibre rope；The outermost forming entirety at power wire core, earthing detection line, wire core and latex bonded fibre rope is surrounded with impregnation strap；Being surrounded with film on described impregnation strap periphery, outside described film, braiding is wound with impregnation line, is extruded with restrictive coating outside described impregnation line.
It is further: resistant fiber pulling woven layer is woven by strong pulling force cellosilk.
Extruding the fluoroplastics of high temperature resistant 250 DEG C of thermoplasticity on resistant fiber pulling woven layer periphery, during extruding, fluoroplastics and resistant fiber pulling woven layer heat are combined into entirety.
The centre position of described power wire core, earthing detection line and wire core is provided with reinforcing fibre silk.
Described latex bonded fibre rope is mixed strand by impregnation line with strong pulling force cellosilk and forms.
The restrictive coating extruded outside described impregnation line is through sulfidization molding, it is ensured that impregnation strap, film, impregnation line and restrictive coating are cross-linked into one.
The invention has the beneficial effects as follows: the cable of stretching resistance random group equipment moving in use, cable dragged, draw, drag, be not susceptible to power wire core when rolling over, phenomenon that wire core is pulled, broken, it is ensured that unit is properly functioning, improves work efficiency.

In figure: 1, power wire core；2, EPDM insulating cement；3, resistant fiber pulling woven layer；4, fluoroplastics；5, screen layer；6, reinforcing fibre silk；7, latex bonded fibre rope；8, impregnation strap；9, film；10, impregnation line；11, restrictive coating；12, earthing detection line；13 wire core.
Detailed description of the invention
The following is a specific embodiment of the present invention, in conjunction with accompanying drawing, the present invention will be further described.
As in figure 2 it is shown, power wire core 1 periphery extrudes EPDM insulating cement 2, EPDM insulating cement 2 periphery being woven with resistant fiber pulling woven layer 3, resistant fiber pulling woven layer 3 periphery extrudes fluoroplastics 4, fluoroplastics 4 periphery is provided with screen layer 5；Wherein resistant fiber pulling woven layer 3 is woven by strong pulling force cellosilk, the fluoroplastics 4 of high temperature resistant 250 DEG C of thermoplasticity are extruded on resistant fiber pulling woven layer 3 periphery, during extruding, fluoroplastics 4 and resistant fiber pulling woven layer 3 heat are combined into entirety, and the overall tensile strength extruding the resistant fiber pulling woven layer 3 after heat is combined and fluoroplastics 4 improves more than 6 times through puller system test than the tensile strength of raw material EPDM insulating cement 2.
Combining shown in Fig. 1,1, two wire core 13 of three power wire core and an earthing detection line 12 that bundle has twisted are clustered together, gap between power wire core 1, earthing detection line 12 and wire core 13 is filled latex bonded fibre rope 7, wherein latex bonded fibre rope 7 is mixed strand by impregnation line with strong pulling force cellosilk and forms, and tests latex bonded fibre rope 7 tensile strength of every mixed glue more than 1100Kg through puller system；Form the outermost wrapped impregnation strap 8 of entirety, wrapped film 9 on impregnation strap 8 periphery at power wire core 1, earthing detection line 12, wire core 13 and latex bonded fibre rope 7, the outer braiding of film 9 is wound around impregnation line 10, extrudes restrictive coating 11 outside impregnation line 10；The restrictive coating 11 extruded outside impregnation line 10 is through sulfidization molding, it is ensured that impregnation strap 8, film 9, impregnation line 10 and restrictive coating 11 are cross-linked into one, improve cable entirety tension, anti-tear performance；The centre position of power wire core 1, earthing detection line 12 and wire core 13 is provided with reinforcing fibre silk 6, improves the tensile strength of power wire core, wire core.
The cable of the stretching resistance of the present invention adds more than 5000Kg through tensile test COMPREHENSIVE CALCULATING than the mechanical strength of original cable.
