Abstract
The invention discloses a high-strength steel wire rope used for port hoisting machines. The high-strength steel wire rope comprises a central strand, a plurality of internal layer strands wrapping the central strand in a twisting mode and a plurality of external layer strands wrapping the internal layer strands in a twisting mode. The central strand comprises a nylon core arranged in the center and a plurality of aramid fiber cores arranged outside the nylon core. A plurality of aramid fiber threads wrap the nylon core in a twisting mode. By the adoption of the mode, the high-strength steel wire has the advantages of being good in fatigue-resisting performance, high in strength, and long in service life.
Description
Technical field
The present invention relates to the steel wire rope technical field, particularly relate to a kind of high strength port crane steel wire rope.
Background technology
Hoisting machinery is a kind of planar transportation equipment, and Main Function has been the displacement of weight, and it can reduce labor intensity, and raises labour productivity.Hoisting machinery is the indispensable part of modern production, especially at harbour machinery, building machinery, in field, plays an important role.Steel wire rope is the important component part of hoisting machinery, and the anti-fatigue performance of existing steel wire rope is bad, and service life is short.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of high strength port crane steel wire rope, has advantages of that anti-fatigue performance is good, intensity is 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 high strength port crane steel wire rope is provided, comprise: central strand, bag are twisted with the fingers at the multiply internal layer thigh of described central strand outside and bag and are twisted with the fingers the multiply outer layer strand in described internal layer thigh outside, described central strand comprises the nylon core and many aramid fiber cores that are arranged on described nylon core outside at the center of being arranged on, and described many aramid line bags are twisted with the fingers in described nylon core outside.
In a preferred embodiment of the present invention, the number of share of stock of described internal layer thigh is 8 strands, and per share internal layer thigh includes core wire and bag is twisted with the fingers steel wire outside eight of described core wire outside.
In a preferred embodiment of the present invention, the number of share of stock of described outer layer strand is 8 strands, and per share outer layer strand includes core wire and bag is twisted with the fingers steel wire outside eight of described core wire outside.
In a preferred embodiment of the present invention, the diameter of described steel wire rope is 2 ~ 2.5cm.
The invention has the beneficial effects as follows: high strength port crane steel wire rope of the present invention has advantages of that anti-fatigue performance is good, intensity is high, long service life.
The accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the embodiment of the present invention, in below describing embodiment, the accompanying drawing of required use is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of high strength port crane of the present invention with steel wire rope one preferred embodiment;
In accompanying drawing, the mark of each parts is as follows: 1, central strand, 2, the internal layer thigh, 3, outer layer strand.
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.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of high strength port crane steel wire rope, comprise: central strand 1, bag are twisted with the fingers at the multiply internal layer thigh 2 of described central strand 1 outside and bag and are twisted with the fingers the multiply outer layer strand 3 in described internal layer thigh 2 outsides, described central strand 1 comprises the nylon core at the center of being arranged on and is arranged on many aramid fiber cores of described nylon core outside, described many aramid line bags are twisted with the fingers in described nylon core outside, described central strand 1 intensity is high, has effectively promoted anti-fatigue performance of the present invention.
The number of share of stock of described internal layer thigh 2 is 8 strands, and per share internal layer thigh includes core wire and bag is twisted with the fingers steel wire outside eight of described core wire outside.
The number of share of stock of described outer layer strand 3 is 8 strands, and per share outer layer strand includes core wire and bag is twisted with the fingers steel wire outside eight of described core wire outside.
The diameter of described steel wire rope is 2 ~ 2.5cm.
High strength port crane steel wire rope of the present invention, have advantages of that anti-fatigue performance is good, intensity is high, long service life.
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.
