Description
Technical field
The utility model belongs to merchant wire technical field, especially improved steel wire rope and steel wire rope goods.
Background technology
Steel wire, as stiffener, is widely applied in optical cable, cable.In layer-twisted type and slotted core cable steel wire operated by rotary motion in optical cable central authorities as central reinforce member; In central-beam tube type fiber optic cable, steel wire is generally placed on beam tube outside, center, and may be many: in self-support cable, except above-mentioned reinforcement steel wire, being referred to as in addition the steel wire rope of messenger wire as extra strong stretching resistance element, is mainly the tension force while bearing the pulling force of self-supporting while installing and operation; In cable, steel wire rope is mainly used in self-supporting cable, identical with self-support cable of effect.
Steel wire rope of the prior art section and structure, typically have 2 kinds, be exactly 1 * 7,1 * 19 structure, in 1 * 7 structure, centre has a steel wire, around this process wire is stranded, is distributed with 6 steel wires, 7 steel wires have identical diameter; In 1 * 19 structure, as shown in Figure 1, centre has a central steel wire 1, around this central authorities' steel wire is stranded, is distributed with 6 steel wire of internal layer 2, around steel wire of internal layer intertwist body, is distributed with 12 cover wires 3, the diameter of central authorities, internal layer, cover wire equates, and for 1 * 19 structure, the center of circle of steel wire of internal layer is on same internal layer circumference 11, the center of circle of cover wire is in same outer periphery 12, and the outer rim of cover wire is on same excircle 13; In above-mentioned 1 * 19 structure, excircle diameter equals 5 single gauges of wire, and it is tangent between cover wire and steel wire of internal layer, having part, has part not tangent, though this structure can reach requirement of strength, but because external diameter is relatively thick, optical cable is in order to reach the minimum requirements of the extrusion molding layer thickness outside steel wire rope, virtually increased cost to the manufacture of optical, electrical cable, virtually make sheath material increase, this mode is lasting for years, with low-carbon environment-friendly, energy-saving and emission-reduction require incompatible.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to disclose a kind of improved steel wire rope; And disclose further the goods that adopt this steel wire rope, they are realized by the following technical solutions.
In embodiment 1 of the present utility model, improved steel wire rope, it includes a central steel wire 1 that is positioned at central authorities, is distributed in outside central steel wire and the six roots of sensation steel wire of internal layer 2 tangent with central steel wire, is distributed in outside steel wire of internal layer and the six roots of sensation cover wire 3 tangent with steel wire of internal layer; On the face of arbitrary cross section: the center of circle of steel wire of internal layer is on same internal layer circumference 11, and the center of circle of cover wire is in same outer periphery 14, and the outer rim of cover wire is positioned on same excircle 13; It is characterized in that: adjacent steel wire of internal layer have outward the steel wire of internal layer adjacent with this tangent and with adjacent cover wire tangent wire of intermediate layer 4 all; The center of circle of wire of intermediate layer on same intermediate layer circumference 12, internal layer circumference, intermediate layer circumference, outer periphery, excircle and central steel wire concentric; Central authorities' steel wire, steel wire of internal layer, cover wire have equal diameter.
In this embodiment, owing to thering is gap between excircle and wire of intermediate layer, cover wire, therefore, effectively reduced the external surface area of steel wire rope, when cable is produced, in the situation that same sheath material, the gap of filling is more, makes cable structure more stable, reliable; Meanwhile, because external surface area reduces, can be around putting longer steel wire rope on same dish tool, saving dish tool cost, cost of transportation.
In embodiment 2 of the present utility model, improved steel wire rope, it includes a central steel wire 1 that is positioned at central authorities, is distributed in outside central steel wire and the six roots of sensation steel wire of internal layer 2 tangent with central steel wire, is distributed in outside steel wire of internal layer and the six roots of sensation cover wire 3 tangent with steel wire of internal layer; On the face of arbitrary cross section: the center of circle of steel wire of internal layer is on same internal layer circumference 11, and the center of circle of cover wire is in same outer periphery 14, and the outer rim of cover wire is positioned on same excircle 13; It is characterized in that: adjacent steel wire of internal layer have outward the steel wire of internal layer adjacent with this tangent and with adjacent cover wire tangent wire of intermediate layer 4 all; The center of circle of wire of intermediate layer on same intermediate layer circumference 12, internal layer circumference, intermediate layer circumference, outer periphery, excircle and central steel wire concentric; Central authorities' steel wire, steel wire of internal layer have equal diameter; The diameter of cover wire is less than the diameter of steel wire of internal layer, and the diameter of wire of intermediate layer is greater than the diameter of steel wire of internal layer; The outer rim of wire of intermediate layer is also positioned on excircle 13.
In this embodiment, although the diameter of cover wire is less than the diameter of steel wire of internal layer, therefore the integral diameter of steel wire rope is less than the diameter of steel wire rope of the prior art, simultaneously, because the diameter of wire of intermediate layer is greater than the diameter of steel wire of internal layer, historical facts or anecdotes has showed under the prerequisite of identical steel wire radical, the overall sectional of steel wire is long-pending long-pending identical with the overall sectional of steel wire in steel wire rope of the prior art, be that tensile strength is identical, but the object that diameter is less, therefore when making cable and other goods, for reaching the minimum thickness of the outside extrusion molding layer of steel wire rope, can make extrusion molding layer diameter less, extruded material consumes object still less.
In embodiment 3 of the present utility model, adopt the steel wire rope goods of above-mentioned improved steel wire rope, it includes improved steel wire rope described above, and improved steel wire rope is positioned at central authorities, and outside steel wire rope, extrusion molding is coated with protective layer 5; Certainly, described protective layer 5 can also be penetrated in the internal clearance of improved steel wire rope.
Steel wire rope described above, is not limited to steel wire, adopts other nonmetallic material also passable, such as fiberglass reinforced plastics.
Therefore, the utlity model has following main beneficial effect: under same intensity condition, external diameter is thinner or profile area is less; More saving dish tool, cost of transportation, the material consumption amount of steel wire rope goods, structure are more reliable and more stable.
