Abstract
The utility model provides a shearer cable with a reinforced control wire, comprising a main cable core and an outer sheath that wraps the outer side of the main cable core, wherein the cable core comprises a power wire core conductor wrapped by a power wire core insulating layer, and a control wire core conductor wrapped by a control wire core insulating layer; and the outer side of the control wire core insulating layer is wrapped by an internal protective layer, a reinforced layer and an external protective layer in sequence from inside to outside. In the shearer cable, a control wire is protected by various ways such as a conductor reinforced by a steel wire, a cable core reinforced by the steel wire and the like so that the control wire is not easy to break when in use, and further the service life of the cable is prolonged.
Description
Technical field
The utility model relates to a kind of cable, the electric cable for coal mining machine of the line that specifically tightens control.
Background technology
At present, the easily broken core of control core in the coal-winning machine rubber sleeve flexible cable that the coal in China industry is used, useful life lack, and are the crucial matching components of restriction coal-winning machine production efficiency.Control core in the electric cable for coal mining machine mainly plays the effect of signal monitoring, but in the cable running because of being subjected to multiple mechanical stress effects such as frequent bending, stretching, easily cause controlling the fracture of core, the control core is in case disconnected core, with the control action that loses coal-winning machine equipment, cause equipment to quit work, cause very big loss to the user.Therefore, the problem that the easily broken core of electric cable for coal mining machine control core, useful life lack is the difficult problem of puzzlement coal industry and cable enterprise always, though the coal industry standard has also been made special regulation to control core material therefor, but still fundamentally is not resolved.
Summary of the invention
The utility model purpose: the purpose of this utility model is at the deficiencies in the prior art, and a kind of electric cable for coal mining machine of the line that tightens control of simple in structure, long service life is provided.
Technical scheme: to achieve these goals, the technical solution of the utility model is a kind of electric cable for coal mining machine of the line that tightens control, comprise the main push-towing rope core and be coated on the oversheath in the main push-towing rope core outside, cable core comprises power line core conductor that is coated with power line core insulation layer and the control line core conductor that is coated with control line core insulation layer, from the outside of control line core insulation layer successively to being coated with sheath, reinforced layer and outer jacket.
For the intensity of the core that tightens control, strengthen its useful life, described control line core conductor is preferably by steel wire and copper wire is stranded forms.
In order to gain in strength, increase the service life equally, described reinforced layer is by braided steel wire or thin around forming.
Beneficial effect: the utility model is strengthened conductor, steel wire by steel wire and is strengthened number of ways such as cable core and protect control line, and it is not in use ruptured easily, thereby has prolonged cable useful life.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only be used to the utility model is described and be not used in the restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims institute restricted portion to the modification of the various equivalent form of values of the present utility model.
As shown in Figure 1, a kind of electric cable for coal mining machine of the line that tightens control, comprise main push-towing rope core 9 and be coated on cable core 9 outer field oversheaths 8, main push-towing rope core 9 comprises power line cable core and control line cable core, described power line cable core comprises three power line core conductors 1, and every power line core conductor 1 outside all is coated with power line core insulation layer 2.Described control line cable core comprises three control line core conductors 3, control line core conductor 3 forms by the strand of steel wire and copper wire bundle or strand is stranded once more for some strands, every control line core conductor 3 outsides all are coated with control line core insulation layer 4, control line cable core skin is provided with sheath 5, reinforced layer 6 and outer jacket 7 from inside to outside successively, and reinforced layer 6 is by braided steel wire or thin around forming.The control line cable core constitutes four-core and three power line cable core strandings constitute the main push-towing rope core.
The control line core conductor uses steel wire to strengthen in the utility model, prolongs the useful life of control line core conductor under extended state repeatedly.Under extended state repeatedly, the power core constantly produces shearing force to the control line system, and the steel wire reinforced layer is set between sheath and outer jacket in the control line system, thereby protection control line system does not rupture because of the shearing force that the power core produces.
