Abstract
The utility model belongs to land cable field, especially diffuse reflection land cable for the logging truck mainly are used as the connecting wire of well logging ground instrument and logging truck. Its cross section is circular, includes shell and the cable that is located the shell, shell outside -in comprises outer jacket, diffuse reflection layer and shielding layer in proper order, the cable comprises with a plurality of piece insulation core s of winding on powerful layer the powerful layer that is located the center, and all the other spaces are passed through the filling layer and are filled. The beneficial effects of the utility model are that: cable tensile strength is high, and it increases by 5~10 times to do all can than breaking of ordinary land cable, the outside diameter of cable is more even, and circularity is better, rely on around the plastic -aluminum filming diffuse reflection layer of package, make the cable have the diffuse reflection function.
Description
Technical field
The invention belongs to logging truck ground field of cables, particularly diffuse-reflectance land cable, be mainly used as the connecting line of logging ground instrument and logging truck.
Background technology
The logging truck land cable of existing conventional structure, is generally all adopt six core rubber set lines, bears pulling force by the middle filling rope made of hemp.Its deficiency is not wear-resisting, and cable is weak to pulling, it does not have diffuse-reflectance function, usually affects being normally carried out of logging operation due to its tensile strength difference.
Summary of the invention
It is an object of the invention to provide the diffuse-reflectance land cable that can solve the problem that the deficiencies in the prior art.
The present invention is to solve that above-mentioned technical problem is adopted the technical scheme that:
Diffuse-reflectance land cable, its cross section is circular, and including shell and the cable being positioned at shell, described shell ecto-entad is made up of outer jacket, diffuse-reflectance layer and screen layer successively；Described cable is made up of the strength layer being centrally located and the some insulated wire cores being wrapped on strength layer, and all the other spaces are filled by packed layer.
Further, described insulated wire cores includes conductor layer and the insulating barrier being extruded on conductor layer.
Further, the material of described outer jacket is polyurethane.
Further, described diffuse-reflectance layer is wrapped plastic-aluminum rete.
Further, the material of described screen layer is aluminum plastic film.
Further, the material of described strength layer is lacing wire.
In sum, the invention has the beneficial effects as follows:
1), cable tensile strength high, increase by 5～10 times than the pull-off force of common land cable；
2), the outside diameter of cable evenly, circularity is better；
3), rely on wrapped aluminum plastic film to form diffuse-reflectance layer, make cable have diffuse-reflectance function.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein, 1 outer jacket, 2 diffuse-reflectance layers, 3 screen layers, semi-finals power layer, 5 insulating barriers, 6 conductor layers, 7 packed layers.
Detailed description of the invention
As it is shown in figure 1, diffuse-reflectance land cable, including shell and the cable being positioned at shell, described shell ecto-entad is made up of outer jacket 1, diffuse-reflectance layer 2 and screen layer 3 successively；Described cable is made up of the strength layer 4 being centrally located and the some insulated wire cores being wrapped on strength layer 4, and insulated wire cores includes conductor layer 6 and is extruded on conductor layer 6 material and is the insulating barrier 5 of polyethylene.Wherein, the material of outer jacket 1 is polyurethane, and the Applicable temperature of polyurethane is-50～85 DEG C and has good wearability, greatly strengthen the scope of application of cable.Diffuse-reflectance layer 2 is wrapped plastic-aluminum rete.Strength layer 4 is lacing wire so that the tensile strength of cable is greatly increased, and uses packed layer 7 that cable is filled circle during stranding.
Above-mentioned detailed description of the invention is only the concrete case of the present invention; the scope of patent protection of the present invention includes but not limited to product form and the style of above-mentioned detailed description of the invention; any diffuse-reflectance land cable meeting claims of the present invention and any person of an ordinary skill in the technical field to its suitably change done or modify, and all should fall into the scope of patent protection of the present invention.
