Abstract
The invention discloses a steel wire rope for a crane. The steel wire rope for the crane comprises a steel wire rope center strand, multiple steel wire rope inner layer strands coating the steel wire rope center strand, and multiple steel wire rope outer layer strands coating the steel wire rope inner layer strands. The steel wire rope center strand is formed by at least three aramid fiber threads through stranding in a twisting mode, and each aramid fiber thread comprises at least one hundred aramid fibers. Through the model, the steel wire rope for the crane has the advantages of good toughness, high tensile strength and long service life.
Description
Technical field
The present invention relates to the rope technique field, particularly relate to a kind of cable wire for crane.
Background technology
Steel wire rope is the flexible cable that many of a kind of usefulness or multiply finer wire twist into, and steel wire rope is to be twisted thigh by the multilayer steel wire, centered by wire rope core, twists with the fingers helically wound rope by some thighs again.In various machineries, for promote, traction, tension and carrying.A main application of steel wire rope is to be used on the hoisting machinery, and existing steel wire rope for hoisting machinery exists the shortcoming that toughness is bad, tensile strength is not high, service life is short.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of cable wire for crane, has advantages of that good toughness, tensile strength are high, long service life.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of cable wire for crane is provided, comprise: the steel wire rope central strand, be coated on the multistrand rope internal layer thigh of described steel wire rope central strand outside and be coated on the multistrand rope outer layer strand of described steel wire rope internal layer thigh outside, described steel wire rope central strand is formed by at least three aramid line doubling twistings, and every aramid line comprises at least one hundred aramid fibers.
In a preferred embodiment of the present invention, the fineness of described aramid fiber is 70 ~ 85D.
In a preferred embodiment of the present invention, the sth. made by twisting of described steel wire rope central strand is to being left-hand lay, and the sth. made by twisting of described steel wire rope internal layer thigh is to being right-laid, and the sth. made by twisting of described steel wire rope outer layer strand is to being left-hand lay.
In a preferred embodiment of the present invention, described steel wire rope internal layer thigh comprises many internal layer thigh steel wires, and described steel wire rope outer layer strand comprises many outer layer strand steel wires, and described outer layer strand gauge of wire is greater than internal layer thigh gauge of wire.
The invention has the beneficial effects as follows: cable wire for crane of the present invention has advantages of that good toughness, tensile strength are high, long service life.
Description of drawings
Fig. 1 is the structural representation of cable wire for crane one preferred embodiment of the present invention;
The mark of each parts is as follows in the accompanying drawing: 1, steel wire rope central strand, 2, steel wire rope internal layer thigh, 3, the steel wire rope outer layer strand.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
See also Fig. 1, the embodiment of the invention comprises:
A kind of cable wire for crane, comprise: steel wire rope central strand 1, be coated on the multistrand rope internal layer thigh 2 of described steel wire rope central strand 1 outside and be coated on the multistrand rope outer layer strand 3 of described steel wire rope internal layer thigh 2 outsides, described steel wire rope central strand 1 is formed by at least three aramid line doubling twistings, and every aramid line comprises at least one hundred aramid fibers.
The fineness of described aramid fiber is 70 ~ 85D.
The sth. made by twisting of described steel wire rope central strand 1 is to being left-hand lay, and the sth. made by twisting of described steel wire rope internal layer thigh 2 is to being right-laid, and the sth. made by twisting of described steel wire rope outer layer strand 3 is to being left-hand lay.
Described steel wire rope internal layer thigh 2 comprises many internal layer thigh steel wires, and described steel wire rope outer layer strand 3 comprises many outer layer strand steel wires, and described outer layer strand gauge of wire is greater than internal layer thigh gauge of wire.
Cable wire for crane of the present invention has advantages of that good toughness, tensile strength are high, long service life, and is simple and practical.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
