Abstract
The invention discloses a steel wire rope for a high-strength lifting device. The steel wire rope for the high-strength lifting device comprises a center strand, an inner coating layer and an outer coating layer. The center strand comprises a plurality of nylon ropes and a plurality of hemp ropes. The nylon ropes are made of nylon fibers and the twist of each nylon rope is 850T/M. The hemp ropes are made of hemp fibers and the twist of each hemp rope is 900T/M. The twist of the center strand is 1000T/M. According to the mode, the steel wire rope for the high-strength lifting device is simple and reasonable in structure, high in flexural fatigue resistance and high in tensile strength.
Description
Technical field
The present invention relates to the steel wire rope technical field, particularly relate to a kind of high strength crane gear steel wire rope.
Background technology
Crane gear refers to for referring to the electromechanical equipment of carrying or moving heavy object.Crane gear can be divided into several classes such as small-sized crane gear, lift, crane and overhead monorail system by the structure difference.
Steel wire rope is extremely important part in crane gear, existing steel wire rope all therein the heart position fiber wire rope core is set, the tensile strength of existing fiber wire rope core is not high, thereby has affected the intensity of steel wire rope integral body.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of high strength crane gear steel wire rope, and simple and reasonable, counter-bending fatigability is high, and tensile strength is high.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of high strength crane gear steel wire rope is provided, comprise: center rope strand, internal coating and external coating, described center rope strand comprises many nylon ropes and the Duo Gen rope made of hemp, described nylon rope adopts nylon fiber to make, and the twist of described nylon rope is 850T/M, and the described rope made of hemp adopts flax fibre to make, the twist of the described rope made of hemp is 900T/M, and the twist of described center rope strand is 1000T/M.
In a preferred embodiment of the present invention, described internal coating is comprised of many interior steel strands.
In a preferred embodiment of the present invention, described external coating is comprised of many outer steel strands.
In a preferred embodiment of the present invention, the diameter of described center rope strand is greater than the diameter of interior steel strand.
The invention has the beneficial effects as follows: high strength crane gear steel wire rope of the present invention, simple and reasonable, counter-bending fatigability is high, and tensile strength is high.
The specific embodiment
Below will the technical scheme in the embodiment of the present invention be clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making all other embodiment that obtain under the creative work prerequisite, belong to the scope of protection of the invention.
The embodiment of the present invention comprises:
A kind of high strength crane gear steel wire rope, comprise: center rope strand, internal coating and external coating, described center rope strand comprises many nylon ropes and the Duo Gen rope made of hemp, described nylon rope adopts nylon fiber to make, the twist of described nylon rope is 850T/M, the described rope made of hemp adopts flax fibre to make, the twist of the described rope made of hemp is 900T/M, nylon rope and the rope made of hemp all have tensile strength preferably, many nylon ropes and the Duo Gen rope made of hemp in conjunction with after, then add the twist of 1000T/M, tensile strength is higher, described center rope strand has oil storage performance preferably simultaneously, improves lubricant effect.
Described internal coating is comprised of many interior steel strands, and described interior steel strand adopts zinc-coated wire to make, and due to the lubrication of center rope strand, the wearing and tearing of interior steel strand inside are less.
Described external coating is comprised of many outer steel strands, and described outer steel strand adopts zinc-coated wire to make, and due to the lubrication of center rope strand, the wearing and tearing of outer steel strand inside are less.
The diameter of described center rope strand is greater than the diameter of interior steel strand.
High strength crane gear steel wire rope of the present invention, simple and reasonable, counter-bending fatigability is high, and tensile strength is high.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or directly or indirectly be used in other relevant technical field, all in like manner be included in scope of patent protection of the present invention.
