Abstract
The cable possesses cable jacket, insulated conductor inside cable jacket, helix framework in center of cable jacket, strength rope in center of helix framework. At least one helix wire groove on helix framework stretched surrounding cable axis, and insulated conductor is embedded to the wire groove. Features of the invented cable are: even stress, any bending direction with high degree of freedom, steel rope supporting all weight of cable, current carrying part of cable not in tension, suspended and laid in horizontal, vertical any direction as well as Light weight and small size.
Description
Affiliated technical field
The present invention relates to a kind of cable, especially a kind of self-supporting cable.
Background technology
Cable generally is used for the conducting electric current, but in some occasion, also need and to carry, occasions such as deep water robot, deep-well probe, deep well submerged pump, ground mobile device, high-altitude lifting hanging ladder, elevator need be used self-supporting cable, its general common structure has following several: suspended cables below a wirerope, respectively put a wirerope in the both sides of Stranded cable conductor wire core,, place wirerope or the like in cable center at the outer armouring wire or the steel band of cable.Though the structure of wirerope below suspended cables is easy to manufacture, when crooked, the degree of freedom of bending direction is restricted, and the wirerope axle center does not overlap with the cable center of gravity during vertical hanging, and internal stress is bigger; A steel cable structure is respectively put in the both sides of Stranded cable conductor wire core, and when cable was crooked, bending direction was restricted equally, and the big production cost of cable volume ratio strengthens; Through the cable of outer armouring, weight is big, and is not flexible; The structure of wirerope is placed by cable center, and center wirerope and Stranded cable core adhesive force are little, and the center wirerope is drawn out easily.
Summary of the invention
In order to overcome the deficiency of existing self-supporting cable, it is good to the purpose of this invention is to provide a kind of bending property, and cable tension is powerful, the non-damageable spiral skeleton of cable core self-bearing type multicore cable.
The technical solution adopted for the present invention to solve the technical problems is: a kind of spiral skeleton self-bearing type multicore cable, has cable jacket, be provided with insulated conductor in the cable jacket, the cable jacket center is provided with the spiral skeleton, spiral frame center is provided with strengthened rope, the spiral skeleton is provided with at least one wire casing that stretches around the cable axis spiral, and insulated conductor is embedded in the wire casing.
Further: the wire casing in described spiral skeleton cross section is the center radiation shape, direction of rotation can be left-handed also can be dextrorotation.
Again further: described insulated conductor is made up of multiply metal material conductor wire core and its outer insulated conductor insulating barrier of coating.
Again further: described strengthened rope is strands steel wire rope or multiply fibre tension rope.
Again further: described multiply metal material conductor wire core conductance is higher relatively, can be filamentary silver, copper wire, aluminium wire, silver-gilt copper wire, tinned copper wire.
Again further: described insulated conductor insulating barrier materials used is PVC, PE, PET, PU.
Further: described cable jacket materials used is PU, PVC, TPE.
Spiral skeleton self-bearing type multicore cable of the present invention, stressed even, bending direction degree of freedom height, be any direction, all weight of cable is born on wirerope, and the current-carrying part of cable does not bear pulling force, self-supporting weight can level, vertical, arbitrarily angled suspension is laid, and volume in light weight is little.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of spiral skeleton self-bearing type multicore cable of the present invention.
Fig. 2 is the cross-sectional view of spiral skeleton self-bearing type multicore cable of the present invention.

1. cable jackets among the figure, 2. insulated conductor, 21. insulated conductor insulating barriers, 22. multiply metal material conductor wire cores, 3. strengthened rope, 4. spiral skeleton, 41. wire casings.
Embodiment
As Fig. 1, spiral skeleton self-bearing type multicore cable shown in Figure 2, has cable jacket 1, cable jacket 1 materials used is PU, PVC, TPE, as required, be provided with six roots of sensation insulated conductor 2 in the cable jacket 1, insulated conductor 2 is made up of multiply metal material conductor wire core 22 and its outer insulated conductor insulating barrier 21 of coating, multiply metal material conductor wire core 22 conductances are higher relatively, can be filamentary silver, copper wire, aluminium wire, silver-gilt copper wire, tinned copper wire, insulated conductor insulating barrier 21 materials useds are PVC, PE, PET, PU, multiply metal material conductor wire core 22 is assembled into one with insulated conductor insulating barrier 21 usefulness extruders.Cable jacket 1 center is provided with spiral skeleton 4, and spiral skeleton 4 centers are provided with a strengthened rope 3, and strengthened rope 3 is strands steel wire rope or multiply fibre tension rope, and strengthened rope 3 is assembled into one with spiral skeleton 4 usefulness extruders.Spiral skeleton 4 is provided with six wire casings 41 that stretch around the cable axis spiral, and the wire casing 41 in spiral skeleton 4 cross sections is the center radiation shape, its direction of rotation can be left-handed also can be dextrorotation.Insulated conductor 2 is embedded in the wire casing 41 of spiral skeleton 4 with cabler, at last core behind the stranding and cable jacket 1 usefulness extruder is assembled into finished cable.
Compare with self-supporting cable as shown in Figure 3, Figure 4, spiral skeleton self-bearing type multicore cable is stressed evenly, and bending direction degree of freedom height can any direction bending, and all weight of cable is born on wirerope, and the current-carrying part of cable does not bear pulling force.Self-supporting weight can level, vertical, arbitrarily angled suspension is laid, and volume in light weight is little.
When steel wire rope is fixed on the terminal equipment, the cable bending property was good when equipment moved, and cable tension is powerful when suspension equipment or trailing cable, cable core is not fragile.Spiral skeleton self-bearing type multicore cable can be widely used in occasions such as deep water robot, deep-well probe, deep well submerged pump, ground mobile device, high-altitude lifting hanging ladder, elevator.
