Utility model content
The utility model mainly solves the technical problem that existing steel wire rope bearing capacity is low, cost is high.
In order to solve the problems of the technologies described above, the utility model embodiment discloses a kind of steel wire rope, comprise a central strand, many outer layer strand and be coated on the layer of polyurethane of described many outer layer strand, described many outer layer strand bags are twisted with the fingers in described central strand periphery, described central strand is compiled sth. made by twisting by several steel wire and is formed, and each outer layer strand is compiled sth. made by twisting by several carbon fiber and formed.
In a preferred embodiment of the present utility model, the quantity of described outer layer strand is eight.
In a preferred embodiment of the present utility model, each outer layer strand periphery is enclosed with layer of polyurethane.
In a preferred embodiment of the present utility model, described central strand is compiled sth. made by twisting by the steel wire that 19 diameters are identical and is formed.
In a preferred embodiment of the present utility model, 19 steel wires of described central strand are divided into three layers according to the mode that ground floor is from inside to outside 1 steel wire, the second layer is 6 steel wires, third layer is 12 steel wires.
In a preferred embodiment of the present utility model, be point cantact between described steel wire.
In a preferred embodiment of the present utility model, described central strand periphery is provided with zinc coat, and described galvanized layer thickness specification is >=90g/ ㎡.
In a preferred embodiment of the present utility model, described gauge of wire is 1.8 ~ 2.0 ㎜.
In a preferred embodiment of the present utility model, the diameter of described central strand is greater than the diameter of described outer layer strand.
Compared to prior art, the steel cord structure that the utility model provides is scientific and reasonable, described central strand is compiled sth. made by twisting by several steel wire and is formed, intensity is high, described outer layer strand is compiled sth. made by twisting by several carbon fiber and is formed, the pulling force that carbon fiber carries is 7 ~ 9 times of steel wire, and weight only has 1/4th of equal steel wire, not only can increase the bearing capacity of whole steel wire rope, and the entire outer diameter of steel wire rope can be reduced, reduce the deadweight of steel wire rope, the bend resistance ability of carbon fiber is obviously better than steel wire simultaneously, the anti-disrumpent feelings ability of steel wire rope is improved, service life extends, cost-saving, the outer layer strand of steel wire rope is also coated with layer of polyurethane, and protection internal layer, makes it shape, and increases flexibility, does not ftracture, long service life.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the generalized section of steel wire rope one preferred embodiment that the utility model provides.
Detailed description of the invention
Be clearly and completely described to the technical scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The utility model discloses a kind of steel wire rope, refers to Fig. 1, is the generalized section of steel wire rope one preferred embodiment that the utility model provides.Described steel wire rope 1 comprises a central strand 11, many outer layer strand 12 and is coated on the layer of polyurethane 13 of described many outer layer strand 12, and described many outer layer strand 12 are wrapped and twisted with the fingers in described central strand 11 periphery.The diameter of described central strand 11 is greater than the diameter of described outer layer strand 12.
Described central strand 11 is compiled sth. made by twisting by several steel wire and is formed.In the present embodiment, described central strand 11 is compiled sth. made by twisting by the steel wire that 19 diameters are identical and is formed, and wherein 19 steel wires are divided into three layers according to the mode that ground floor is from inside to outside 1 steel wire, the second layer is 6 steel wires, third layer is 12 steel wires.It is point cantact between described steel wire.
Further, described central strand 11 periphery is also provided with zinc coat 111, prevents the steel wire of central strand 11 to be oxidized.Described zinc coat 111 thickness specification is >=90g/ ㎡.
