It the utility model is related to steel wire rope technical field, specially engineering machinery luffing specialized wire rope.
Background technology
Steel wire rope be it is a kind of with intensity is high, elasticity is good, from heavy and light and flexible good important component, be widely used in machine A variety of industries such as tool, shipbuilding, mining, metallurgy and forestry, the flexible cable twisted into more or multiply finer wire, are removed in material In fortune machinery, for being lifted, drawing, tensing and carrying is used, at present, existing steel wire rope is widely used in large space structure In construction project, thus it is increasing to the demand of steel wire rope, so as to the quality requirement more and more higher to steel wire rope, major embodiment Require high in highly corrosion resistant, fatigue performance, existing steel wire rope is mainly that smooth surface or zinc-plated round-strand rope, steel cord structure are steady It is qualitative, fastening performance, wear-resistant not good enough, it is impossible to adapt to demand of the space structure field to large-scale construction project.
The steel cable that tower crane lifting uses at present is:The common stocks such as 18x 7,35 (w) x7 or compacting stock steel cable do Winding rope. For the tower crane that lifting altitude is larger, because the lift stroke of steel cable is big, common steel cable is to produce steel cable to play torsion easily in lifting Rotated with steel cable, so as to cause service life short.Steel cable is frequently changed, influences the operating efficiency of tower crane.Sometimes steel rope breaking, Caused by lose it is bigger.
The content of the invention
The purpose of this utility model is to provide engineering machinery luffing specialized wire rope, to solve to carry in above-mentioned background technology The problem of going out, possessed beneficial effect are:The minimum breaking force value of steel cable improves 15% ~ 20%, and shock resistance improves, The Stability Analysis of Structures of steel cable, service life improve 2.5 ~ 3 times.Serve and save steel, save the energy, the low consumed effect of drop.
To achieve the above object, the utility model provides following technical scheme:Engineering machinery luffing specialized wire rope, including Steel wire rope body, the steel wire rope body include first layer rope strand, second layer rope strand body and steel wire rope body stock core, and Two layers of rope strand body outsourcing, which are twisted with the fingers, first layer rope strand, and the intrinsic second layer rope strand bag of second layer rope strand is twisted with the fingers in steel wire rope body stock The outside of core, the first layer rope strand are disposed with first layer rope strand stock core, first layer rope strand compound steel silk, from inside to outside One layer of rope strand, two layers of steel wire and first layer rope strand layer of steel wire, the second layer rope strand layer of steel wire bag on the outside of the second layer rope strand Sth. made by twisting is filled out between the outside of second layer rope strand stock core, the steel wire rope body stock core and second layer rope strand filled with second layer rope strand Layer is filled, first layer strands fit layer is filled between first layer rope strand and the second layer rope strand body.
Preferably, the steel wire rope body stock core is twisted with the fingers by seven strands of steel wire bags and formed.
Preferably, the second layer strands fit layer and first layer strands fit layer are made by EPDM rubber grain material.
Preferably, the first layer rope strand layer of steel wire, two layers of steel wire of first layer rope strand, first layer rope strand compound steel silk and Second layer rope strand layer of steel wire is made by stainless steel component.
Preferably, the first layer rope strand is twisted with the fingers by 30 one steel wire bag and formed.
Compared with prior art, the beneficial effects of the utility model are:Compared with prior art, steel cable is most for the equipment Small rupture pull force value improves 15% ~ 20%, and shock resistance improves, the Stability Analysis of Structures of steel cable, and service life improves 2.5 ~ 3 times. Serve and save steel, save the energy, the low consumed effect of drop;The wire rope core of compacting stock composition forges through overall again after twisting, The twist direction of wire rope core and the twist direction of steel cable are on the contrary, to balance the moment of torsion of the inside and outside layer of steel cable;The utility model have steel wire strand bag twist with the fingers and Into intensity is higher, the rotation for the steel cable that can determine, beats torsion problem, improves the service life of steel cable.
