Abstract
The utility model provides a kind of trailing cable of resistance to alternating bending, relate to industrial cable technical field, it comprises rubber sheath and cable core, described cable core comprises obturator and is wrapped in some wires in described obturator, described obturator is hollow structure inside and its outer peripheral face parallel interval is provided with some grooves, the packing be made up of resilient foam material is filled with in described groove, the outer peripheral face of described obturator is also enclosed with a screen be wound by the polyester belt of surperficial metal-plated membrane, the outside of described screen is provided with a braided fiber reinforcing layer, described rubber sheath wraps tightly the outside at braided fiber reinforcing layer.The trailing cable of this resistance to alternating bending can be avoided frequent circle to walk around wire in journey breaking the situation of core and sheath cracking well, and useful life is longer.
Description
Technical field
The utility model relates to industrial cable technical field, the trailing cable of particularly a kind of resistance to alternating bending.
Background technology
In prior art, in colliery, the occasion digger that uses in the down-hole such as iron ore, zinc ore all needs to use trailing cable, and one end of trailing cable is fixed on Energy control cashier's office in a shop, and the other end is connected with the take-up cylinder on digger.Need during owing to using often mobile, frequent circle around, so require that cable has good tension and bending property.The wider trailing cable of current use is common rubber sleeve flexible cable (the i.e. sheathed soft rubber sheath in the outside of cable core, cable core comprises some wires and fills up the obturator in the space between wire and soft rubber sheath), this trailing cable is walked around in journey at long frequent circle and is easily occurred that cable conductor breaks the situation of core, in addition, owing to not easily there is Relative sliding between obturator and rubber sheath, the i.e. small slip of enable generation, frictional force when it slides is also very large, easily cause rubber sheath bulge, cracking, thus lose the protective effect of right sheath to wire, the useful life of cable is shorter.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of trailing cable of resistance to alternating bending, and it can avoid frequent circle to walk around wire in journey breaking the situation of core and sheath cracking well, and useful life is longer.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of trailing cable of resistance to alternating bending, comprise rubber sheath and cable core, described cable core comprises obturator and is wrapped in some wires in described obturator, described obturator is hollow structure inside and its outer peripheral face parallel interval is provided with some grooves, the packing be made up of resilient foam material is filled with in described groove, the outer peripheral face of described obturator is also enclosed with a screen be wound by the polyester belt of surperficial metal-plated membrane, the outside of described screen is provided with a braided fiber reinforcing layer, described rubber sheath wraps tightly the outside at braided fiber reinforcing layer.
Preferably, described obturator is made up of silica gel, and described packing is that foaming EVA material is made, and described braided fiber reinforcing layer is woven by Fanglun 1414 and forms.
The beneficial effect that the utility model obtains is: the obturator that the trailing cable of the resistance to alternating bending that the utility model provides have employed hollow structure inside wraps up wire, and at the outer setting groove of obturator, the packing that flexible foaming material is made is provided with in groove, when cable bend, the oppressed distortion of packing in obturator and groove, thus effectively prevent wire and to break the situation of core, in addition, outer peripheral face due to obturator has wrapped up a screen be wound by the polyester belt of surperficial metal-plated membrane, cable is bent with time stretching, the coefficient of sliding friction between obturator and this screen is less, frictional force is less, the braided fiber reinforcing layer of screen outside further enhancing the tensile strength of cable and effectively protects rubber sheath simultaneously, make rubber sheath bulge in actual use, the situation of cracking greatly reduces, improve the useful life of trailing cable largely.
Accompanying drawing explanation
Fig. 1 is cross section structure schematic diagram of the present utility model;
Reference numeral is:
1---rubber sheath 2---obturator 3---wire 4---packing 5---screen 6---braided fiber reinforcing layer.
Embodiment
For the ease of the understanding of those skilled in the art, be further described the utility model below in conjunction with embodiment and accompanying drawing, the content that execution mode is mentioned is not to restriction of the present utility model.
As shown in Figure 1, a kind of trailing cable of resistance to alternating bending, comprise rubber sheath 1 and cable core, described cable core comprises obturator 2 and is wrapped in the some wires 3 in described obturator 2, described obturator 2 is for hollow structure inside and its outer peripheral face parallel interval is provided with some grooves, the packing 4 be made up of resilient foam material is filled with in described groove, the outer peripheral face of described obturator 2 is also enclosed with a screen be wound by the polyester belt of surperficial metal-plated membrane 5, the outside of described screen 5 is provided with a braided fiber reinforcing layer 6, described rubber sheath 1 wraps tightly in the outside of braided fiber reinforcing layer 6.
In the present embodiment, obturator 2 pairs of wires 3 that this trailing cable have employed hollow structure inside wrap up, and at the outer setting groove of obturator 2, the packing 3 that flexible foaming material is made is provided with in groove, when cable bend, the oppressed distortion of packing 3 in obturator 2 and groove, thus effectively prevent wire 3 and to break the situation of core, in addition, outer peripheral face due to obturator 2 has wrapped up a screen be wound by the polyester belt of surperficial metal-plated membrane 5, cable is bent with time stretching, the coefficient of sliding friction between obturator 2 and this screen 5 is less, frictional force is less, the braided fiber reinforcing layer 6 of screen 5 outside further enhancing the tensile strength of cable and effectively protects rubber sheath 1 simultaneously, make rubber sheath 1 bulge in actual use, the situation of cracking greatly reduces, improve the useful life of trailing cable largely.
Preferably, described obturator 2 is made up of silica gel, and described packing 4 is that foaming EVA material is made, and described braided fiber reinforcing layer 6 is woven by Fanglun 1414 and forms.
Above-described embodiment is the utility model preferably implementation, and in addition, the utility model can also realize by alternate manner, and under the prerequisite not departing from the technical program design, any apparent replacement is all within protection range of the present utility model.
The improvements of the utility model relative to prior art are understood more easily in order to allow those of ordinary skill in the art, accompanying drawings more of the present utility model and description are simplified, and for the sake of clarity, present specification is omitted some other elements, and those of ordinary skill in the art it is to be appreciated that these abridged elements also can form content of the present utility model.
