Description
Technical field
The utility model relates to a kind of colliery and uses cable, relates to the reinforced coal-winning machine rubber sleeve flexible cable of a kind of braided steel wire specifically.
Background technology
The coal-winning machine rubber sleeve flexible cable of domestic production at present all is to produce according to coal industry standard MT 818.2～818.4-2009; It is respectively: MT 818.2-2009 " cable part 2: rated voltage 1.9/3.3kV and following soft cable of coal mining machine are used in the colliery "; MT 818.3-2009 " reinforced flexible cable is kept watch on cable the 3rd part: rated voltage 1.9/3.3kV and the shielding of following coal-winning machine in the colliery ", MT 818.4-2009 " colliery is with cable the 4th part: rated voltage 1.9/3.3kV and following coal-winning machine metallic shield flexible cable ".Wherein: rated voltage 1.9/3.3kV and following soft cable of coal mining machine and rated voltage 1.9/3.3kV and following coal-winning machine metallic shield flexible cable, cable cover(ing) is the individual layer sheath, sheath does not have stiffener; Reinforced flexible cable is kept watch in the shielding of rated voltage 1.9/3.3kV and following coal-winning machine, and cable cover(ing) is a duplex sheath, adopts zinc-coated wire between the inside and outside sheath and the tin-coated copper tow closes or stranded strand braiding or twine reinforcement, the double ground wire of doing of reinforced layer.
The coal cutter sheathed rubber sleeve flexible cable of individual layer among MT 818.2-2009 and the MT 818.4-2009 does not have stiffener; Be applied to the mechanical loads such as pulling force, bending stress, distorting stress and mechanical shock on the cable in the coal-winning machine course of work; The overwhelming majority is born by cable conductor; Often causing the control line core conductor or the power line core conductor of cable that disconnected core accident takes place, is to cause cable short main cause in useful life.Though the coal-winning machine rubber sleeve flexible cable among the MT 818.3-2009 has stiffener; But the intensity of tinned copper wire is lower; Zinc-coated wire and tin-coated copper tow close or the intensity of stranded strand inhomogeneous, the booster action of reinforced layer is not strong, and; The structural shape of product is single, can not fully satisfy the instructions for use of coal enterprise.
Summary of the invention
The purpose of the utility model provides a kind of braided steel wire reinforced coal-winning machine rubber sleeve flexible cable to existing weak point in the above-mentioned prior art just.The cable of the utility model is through increasing zinc-coated wire braiding reinforced layer in the sheath of various model coal-winning machine rubber sleeve flexible cables in MT 818.2-2009 and MT 818.4-2009; Reduce the various mechanical stresses that cable conductor receives; Improve tension, counter-bending, antitorque commentaries on classics and the mechanical shock resistance of cable, reach the prolongation coal-winning machine rubber sleeve flexible cable purpose in useful life.
The purpose of the utility model can realize through following technique measures:
The reinforced coal-winning machine rubber sleeve flexible cable of the braided steel wire of the utility model comprises by the ground cable core, around a control line cable core and three cable conductors that the power line cable core constitutes of ground cable core setting, and is wrapped in cable conductor outer inner restrictive coating, braided steel wire reinforced layer and external sheath layer successively.
Braided steel wire reinforced layer described in the utility model is to be formed through braiding by the zinc-coated wire that many bundles close or are twisted into behind the strand.
Ground cable core described in the utility model is made up of ground wire core conductor and ground core semiconductive integument; Said control line cable core is made up of control line core conductor, control line core insulation layer, control line cable core external sheath layer; Said power line cable core is made up of power line core conductor, power line core insulation layer, power core screen (semiconductive or metal screen layer).
More specifically say: the utility model utilizes the high-strength characteristic of zinc-coated wire to remedy the intensity defective of high resiliency, low modulus rubber sheath; In the cable use; Bear mechanical loads such as most of pulling force, bending stress, distorting stress and mechanical shock by the reinforced layer of cable; Reduce the various mechanical stresses that cable conductor receives, improve the mechanical and physical performance of cable.Change the individual layer jacket structure of various model coal-winning machine rubber sleeve flexible cables among MT 818.2-2009 and the MT 818.4-2009 into the duplex sheath structure, the cable core structure of cable is constant, between inside and outside sheath, reinforced layer is set.Reinforced layer adopts the zinc-coated wire in suitable line footpath, after many bundles close or are twisted into strand, weaves to form, and reaches suitable percentage of braiding coverage; In the braiding reinforced layer, add 2 strands or 4 strands and the identical tinned wird of zinc-coated wire strand structure, make the metal knitted screen of reinforced layer and ground wire core conductor or power core constitute supervision or measurement loop; In the rubber jacket formula, add rubber adhesive; Develop special high-performance sheath glue; The performance of sheath glue meets the regulation of XH-03A type among the GB/T 7594.7-1987 " electric wire rubber insulation rubber sheath the 7th part: 65 ℃ of heavy types are not prolonged combustion rubber sheath "; Fire resistance is excellent, has high bonding strength between sheath glue and reinforced layer; Adopt that rational sheath glue is mixing, the reinforced layer braiding, oversheath is extruded and continuous vulcanization technology.
The beneficial effect of the utility model is following:
Because zinc-coated wire has enough mechanical strengths, the decay resistance of excellence and good softness, many steel wires weave after bundle closes or is twisted into strand, and the mechanical strength of reinforced layer is high, and intensity uniformity, structural stability and processing performance are good; Keep watch on or measure the integrity that the loop can be measured the insulation level of cable inner sheath at any time or monitor the cable inner sheath in real time, the security reliability of cable is high; The bonding effect of reinforced layer and sheath is good, and the embedding of sheath glue completely weaves the whole spaces in the reinforced layer, and reinforced layer and sheath form overall structure, and the stress that has improved cable disperses and the deformation restorability.Cable intensity is high, flexibility is good, Stability Analysis of Structures, and cable can directly pull use, and the minimum bending radius of cable is 15 times of cable size.
