Abstract
The invention discloses a flexible cable for a coal mining machine, comprising a power line wrapped in a sheath, a ground wire core conductor and a control cable formed by a plurality of strands of control wire cores, wherein each control wire core comprises a copper conductor twisted on a reinforced element in a compounding way as well as an insulation bush wrapping outside the copper conductor, an inner envelope and an outer envelope are simultaneously vulcanized and wrap outside the plurality of strands of control wire cores, and a fiber woven reinforced layer is arranged between the inner envelope and the outer envelope; and the reinforced element is made of high-strength high-modulus polyethylene fibers. The flexible cable for the coal mining machine provided by the invention overcomes the defect of easy fracture of the control wire cores of the traditional flexible cable and prolongs the service life of the cable for the mining machine; in the invention, the service life of the cable can be prolonged to 2-3 years under the premise of not increasing the weight of the cable; and the reinforced element is made of the high-strength high-modulus polyethylene fibers, which further enhances the flexibility of the cable during bending.
Description
Technical field
The present invention relates to a kind of cable, especially a kind of flexible cable that is applicable to the coal mining machine.
Background technology
Existing soft cable of coal mining machine usually by three power cores and be coated on rubber insulation layer on the conductor, core, control core and sheath constitute, it is frequent crooked that weak point is that cable in use needs, the as easy as rolling off a log broken string of control core.Coal-winning machine mainly plays the effect of signal monitoring with the control core of cable; but cable in running because of being subjected to multiple mechanical stress effects such as frequent bending, stretching; easily cause controlling the fracture of core; and the control core will be in case fracture will lose the monitoring and protection effect; and cause equipment to stop operating; had a strong impact on user's use, caused very big loss to the user.
Summary of the invention
Technical problem to be solved by this invention provides a kind of flexible cable for coal mining machine, has overcome the shortcoming of existing flexible cable control core frangibility, has prolonged the useful life of mining machine cable.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of flexible cable for coal mining machine, comprise power line, ground wire core conductor that is wrapped in the sheath and the control cable that constitutes by multiply control core, the control core constitutes by twisting copper conductor on reinforcing element and the insulating case that is wrapped in outside the copper conductor again, multiply control core is wrapped with the inner cladding and the surrounding layer of sulfuration simultaneously, is provided with the fibrage reinforced layer between inner cladding and the surrounding layer.
Reinforcing element is the high strength and modulus polyethylene fibre.
A kind of flexible cable for coal mining machine provided by the invention, because the copper conductor at the control core of control cable twists again on reinforcing element, make that in use controlling core is convenient to crooked flexible, make the power that puts on the control core, can be cushioned because of the elasticity and the flexibility of reinforcing element, thereby fundamentally solved the shortcoming of the easily broken core of control line chip bending, increased the flexibility when cable is crooked, make cable when bearing 6 times of cable sizes crooked, be not easy to fracture, multiply control core outer inner cladding and surrounding layer vulcanize simultaneously, make inner cladding and surrounding layer be closely linked, cooperate the fibrage reinforced layer, strengthened the relative slipping property of control cable inner control core, made the control core when stressed, can access certain buffering, thereby prolonged useful life; The present invention is not increasing under the weight situation of cable, and the useful life that can improve cable is to 2-3; Reinforcing element is selected the high strength and modulus polyethylene fibre for use, and impact absorption can be than high nearly one times of contraposition aramid fiber, and resistance to wear is good, and coefficient of friction is little, has further increased the flexibility when cable is crooked.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, the present invention includes power line 14, ground wire core conductor 12 that is wrapped in the sheath 13 and the control cable that constitutes by multiply control core, the control core constitutes by twisting copper conductor 7 on reinforcing element 6 and the insulating case 8 that is wrapped in outside the copper conductor 7 again, multiply control core is wrapped with inner cladding 9 and surrounding layer 11, is provided with fibrage reinforced layer 10 between inner cladding 9 and the surrounding layer 11.
Reinforcing element 6 is the high strength and modulus polyethylene fibre.
Outside reinforcing element 6, adopt the tinned copper wire braiding to form the control line core conductor for 2 to 3 layers, the count of the fibrage reinforced layer 10 that is provided with in the inner cladding 9 of control core and the surrounding layer 11 should be controlled between 40～60%, extrude the inner cladding 9 that wouldn't vulcanize when extruding earlier, braided fiber weaves reinforced layer 10 again, braiding extrudes surrounding layer 11 after finishing again, extrudes inner cladding 9 and surrounding layer 11 to be vulcanized together after finishing.
