Abstract
The utility model provides a multistrand wire rope, comprising twelve outer-layer strands and one metal core, wherein the outer-layer strands are uniformly arrayed in the periphery of the metal core, the metal core comprises a metal core outer layer formed by four main strands and four filling strands, and a metal core inner-layer strand, each outer-layer strand consists of seventeen to twelve-one wire ropes, the main strands and the filling strands are arrayed in the periphery of the metal core inner-layer strand, and the main strands are spaced from the filling strands. The multistrand wire rope has very good flexibility and is suitable for being used in occasions with complex pulley systems; the wire rope with the structure has good twisting resistance and rotating stability, when the wire rope is applied to the occasions with the complex pulley systems, the stress contact surface between the wire rope and a pulley groove is larger than that between the originally-used wire rope and the pulley groove, the wire rope forms an oval stress surface in the pulley groove, so that contact points between the wire rope and the groove are more, the contact pressure between the circumference of the wire rope and a pushing part is reduced to the greatest extent, and further the wear of critical parts of the wire rope is reduced.
Description
Technical field
The utility model relates to a kind of steel wire rope, is a kind of multistrand rope with being specifically related to.
Background technology
The multistrand rope that the lifting means such as crane, truck crane, workshop overhead traveling crane use, because equipment reel reduces, pulley system is more complicated, flexibility, rupture pull force to steel wire rope are had higher requirement, and the isostructural steel wire rope of 8*19 of the prior art, 18*7 can not better meet the demands.
Utility model content
The utility model object is that a kind of multistrand rope is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of multistrand rope, comprise 12 outer layer strand and 1 metal-cored, described outer layer strand is arranged in metal-cored periphery equably; Wherein metal-cored including again by 4 main strand and 4 metal-cored skin and metal-cored internal layer thighs that filling thigh forms, and each outer layer strand is made up of 17 to 21 steel wires respectively; Described main strand with fill strand annular array in the periphery of metal-cored internal layer thigh, and each main strand with fill interval setting between thigh.
Further, described metal-cored internal layer thigh is twisted with the fingers by 47 steel wire bags the structure thigh forming and is formed.
Further, wherein each outer layer strand is made up of 19 steel wires.
Further, described main thigh also has 19 steel wires to form, and is made up of 7 steel wires and fill thigh.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Multistrand rope described in the utility model has extraordinary flexibility, is adapted at using in the occasion of complicated pulley system, and the steel wire rope of the anti-rotation performance of this multistrand rope in is compared to existing technology much bigger, and long service life; The anti-turn-knob of steel wire rope of this structure, rotational stabilization are good, when using in the occasion that it is applied to complicated pulley system, the stressed contact-making surface of itself and pulley groove will exceed the steel wire rope of original use, it forms oval-shaped stress surface in pulley groove, make the contact point between itself and groove more, can reduce to greatest extent the contact between circumference and the pushing portion of steel wire rope, and then reduce the wearing and tearing of steel wire rope key position; The steel wire rope percentage elongation of this structure, diameter change littlely simultaneously, have good rustless property.
Brief description of the drawings
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
The structural representation that accompanying drawing 1 is multistrand rope described in the utility model;
Wherein: 1, outer layer strand; 2, metal-cored; 3, main strand; 4, fill thigh; 5, structure thigh; 6, metal-cored internal layer thigh.
Detailed description of the invention
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Accompanying drawing 1 is multistrand rope described in the utility model, comprises that 1 and 1 of 12 outer layer strand are metal-cored 2, and described outer layer strand 1 is arranged in metal-cored 2 periphery equably; Wherein metal-cored 2 include again by 4 main strand 3 and 4 the filling strand 4 metal-cored skins that form and metal-cored internal layer thigh 6, and each outer layer strand 1 is made up of 17 to 21 steel wires respectively; Described main thigh 3 and filling strand 4 annular arrays are in the periphery of metal-cored internal layer thigh 6, and interval setting between each main thigh 3 and filling thigh 4.
Wherein said metal-cored internal layer thigh 6 is twisted with the fingers by 47 steel wire bags the structure thigh 5 forming and is formed; Wherein each outer layer strand 1 is made up of 19 steel wires; Described main strand 3 also has 19 steel wires to form, is made up of 7 steel wires and fill thigh 4.
In multistrand rope described in the utility model metal-cored 2 is by 4 main strand 3, filling strand 4 12 strands of forming with 4 structure thighs 5 and high voltage bearing nylon core for 4 contacts and is once twisted by line, it has extraordinary flexibility, be particularly suitable for using in the occasion that has complicated pulley system, wherein softness is the maximum feature of this multistrand rope, the steel wire rope of its anti-rotation performance in is compared to existing technology much bigger, and service life is very long; The anti-turn-knob of steel wire rope of this structure, rotational stabilization are good, by special technological design, metal-cored 2 and outer layer strand 1 between to be phase reverse lay metal-cored 2 pin down with outer layer strand 1 in the time reversing mutually to, this steel wire rope, and then cushioned the knob phenomenon of this steel wire rope.When using in the occasion that it is applied to complicated pulley system, the stressed contact area of itself and pulley groove will exceed the steel wire rope of original use, it is in the stressed position of the best in pulley groove, form oval-shaped stress surface, this is that other products cannot be by comparison, make the contact point between itself and groove more, can reduce to greatest extent the contact between circumference and the pushing portion of steel wire rope, and then reduced the wearing and tearing of steel wire rope key position; The steel wire rope percentage elongation of this structure, diameter change littlely simultaneously, and metal-cored 2 in this steel cord structure is to adopt particular design, its close structure, and rupture pull force is large, diameter changes little, compared with other products, elastic modelling quantity is high, and in the time of load-carrying acceleration-deceleration, the rope footpath of its steel wire rope changes little.The steel wire rope of this structure has good rustless property simultaneously, and it lubricates to make to synchronize with steel wire rope and carries out, and lubricated lasting retention time is long, in the process using, only needs user to carry out regular oiling to steel wire rope surface.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
