Technical field
The present invention relates to steel wire field, relate in particular to a kind of steel wire rope.
Background technology
Steel wire rope is the very large a kind of consumptive material of use amount in producing, living, and directly affects efficiency and the safety of production, life the service life of steel wire rope.
Some wire rope cores adopt hemp core, and some steel wire ropes adopt steel core, although wherein steel core can be gained in strength, distinctive physical property rigidity is too strong, easily disconnected; Although the lubricated steel wire of hemp core is effective, intensity is low; Simultaneously steel wire rope, for a long time in the adverse circumstances such as high humidity, soda acid erosion, rubs between rope strand when use, and easily abrasion and corrosion has affected life-span of steel wire rope greatly.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of steel wire rope, Wick oiling is effective, steel wire rope is wear-resisting, corrosion-resistant, has increased the compactedness between each rope strand simultaneously, makes steel wire rope tightr, has extended service life of steel wire rope.
A kind of steel wire rope; comprise wire rope core, rope strand and sheath, wire rope core outer surface is enclosed with the coating layer that polyurethane is made, and rope strand outer surface is enclosed with the protective layer that carborundum is made; sheath extruding is positioned at wire rope core and the rope strand of sheath inside, close contact between coating layer and protective layer, between adjacent protective layer.
Preferably, coating layer absorption has lubricant.
Preferably, polyurethane comprises following parts by mass component: 50～60 parts of polyether polyol, 40～50 parts of vulcabond, 8～12 parts of chain extenders, 0.1～0.5 part of crosslinking agent, 0.1～0.5 part of oil absorbent.
Preferably, coating layer thickness is 3mm～6mm, and protective layer thickness is 2mm～5mm.
Preferably, wire rope core comprises many carbon fiber wires, and wherein a carbon fiber wire is positioned at middle part, and other carbon fiber wires are around the carbon fiber wire that is positioned at middle part, many carbon fiber wire close contacts.
Preferably, rope strand is made up of 3 steel wires, and on same rope strand cross section, the cross section circle of 3 steel wires is tangent between two, and rope strand distributes around wire rope core.
Preferably, jacket outer surface is provided with graduation mark.
Compared with prior art; the present invention has following beneficial effect: steel wire rope provided by the invention comprises wire rope core, rope strand and sheath; wire rope core outer surface is enclosed with the coating layer that polyurethane is made; rope strand outer surface is enclosed with the protective layer that carborundum is made; sheath extruding is positioned at wire rope core and the rope strand of sheath inside, close contact between coating layer and protective layer, between adjacent protective layer.Polyurethane has good oil absorption, and the grease of coating layer absorption can lubricate wire rope core and rope strand, alleviates the wearing and tearing that between wire rope core inside, rope strand, friction causes mutually; The protective layer tool that carborundum is made has good wearability and corrosion resistance, also avoids direct friction between rope strand, prolonging service life of steel wire simultaneously.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
Accompanying drawing indicates as follows: 1-protective layer, 2-steel wire, 3-coating layer, 4-carbon fiber wire, 5-sheath.
Detailed description of the invention
Referring to Fig. 1, below in conjunction with accompanying drawing, the present invention is described in detail.
For ease of understanding the present invention, it is as follows that the present invention enumerates embodiment.It will be understood by those skilled in the art that described embodiment helps to understand the present invention, should not be considered as concrete restriction of the present invention.
The steel wire rope of the present embodiment; comprise wire rope core, rope strand and sheath 5; wire rope core outer surface is enclosed with the coating layer 3 that polyurethane is made; rope strand outer surface is enclosed with the protective layer 1 that carborundum is made; sheath 5 extruding are positioned at wire rope core and the rope strand of sheath inside; close contact between coating layer 3 and protective layer 1, between adjacent protective layer 1, coating layer 3 absorption have lubricant.
Polyurethane material has good tensile strength, tearing toughness, resistance to impact, ABRASION RESISTANCE, weatherability, hydrolytic resistance, oil resistivity, oil absorption, the advantage such as nonpoisonous and tasteless.While preparing steel wire rope, polyurethane coating layer 3 is adsorbed to moderate lubrication agent, lubricant can lubricate wire rope core and rope strand, alleviates the wearing and tearing that between wire rope core inside, rope strand, friction causes mutually, solves wire rope core and the poor problem of rope strand lubricant effect; Silicon carbide has the features such as stable in properties, corrosion-resistant, ABRASION RESISTANCE, quality are light, shock resistance, and the wearing and tearing that carborundum protective layer 1 can alleviate between rope strand and rope strand and extraneous direct friction cause have extended service life of steel wire rope; Sheath 5 extruding are positioned at wire rope core and the rope strand of sheath inside, and close contact between coating layer 3 and protective layer 1, between adjacent protective layer 1, has increased the compactedness between each rope strand, makes steel wire rope tightr.
Polyurethane comprises following parts by mass component: 50～60 parts of polyether polyol, 40～50 parts of vulcabond, 8～12 parts of chain extenders, 0.1～0.5 part of crosslinking agent, 0.1～0.5 part of oil absorbent.In the present embodiment, chain extender is a kind of in propylene glycol, diethanol amine, BDO or at least 2 kinds of combinations, and the polyurethane making also has good oil absorption and oil storage performance simultaneously.
Preferably, wire rope core comprises many carbon fiber wires 4, and wherein a carbon fiber wire 4 is positioned at middle part, and other carbon fiber wires 4 are around the carbon fiber wire 4 that is positioned at middle part, many carbon fiber wire 4 close contacts.Take such setting make 4 of carbon carbon fiber wires compacter, be difficult to slide.In the present embodiment, carbon fiber wire 4 TENSILE STRENGTH, more than 3000Mpa, are the more than 6 times of steel wire, have stronger pulling force, and quality only have 1/4 of equal steel wire.
Preferably, rope strand is made up of 3 steel wires 2, and on same rope strand cross section, the cross section circle of 3 steel wires 2 is tangent between two, and rope strand distributes around wire rope core.2, steel wire, rope strand Contact closely, Stability Analysis of Structures.
