Domestic and international steel wire rope manufacturing enterprise has all carried out large quantifier elimination to this large gauge, high strength, anticorrosion steel wire rope, and because steel wire rope specification is large, intensity of steel wire is high, and zinc layer weight is large, makes steel wire rope have high rupture pull force, strong corrosion resistant ability.
Utility model content
The purpose of this utility model is to provide a kind of offshore drilling platforms anchor line, solves offshore drilling platforms anchor line of the prior art, can not meet the problem of large gauge, high strength, high rupture pull force and strong corrosion resistant ability simultaneously.
The technical scheme that the utility model adopts is, a kind of offshore drilling platforms anchor line, structural representation is 6 × 36WS+IWR (6 × 7+1 × 7), is made up of six roots of sensation steel wire rope outer layer strand, six roots of sensation steel core rope outer layer strand and a steel core rope central strand; The individual wire surface of all steel wire ropes and steel core rope is zinc coat.
Offshore drilling platforms anchor line of the present utility model, is further characterized in that:
Steel wire rope outer layer strand profile is round, structural representation is 1-7-7+7-14, be made up of 36 zinc-coated wires, concrete structure is: around a core wire, twisting has compound steel silk successively, i.e. seven steel wire of internal layer, spaced seven outer little silks and seven outer large silks successively, 14 outermost layer steel wires.
Steel core rope outer layer strand profile is round, and structural representation is 1-6, is made up of seven zinc-coated wires, and namely around a steel core rope outer layer strand central hair, twisting has the outer silk of six roots of sensation steel core rope outer layer strand.
Steel core rope central strand profile is round, and structural representation is 1-6, is made up of seven zinc-coated wires, and namely around a steel core rope central strand central hair, twisting has the outer silk of six roots of sensation steel core rope central strand.
The beneficial effects of the utility model are, this structural representation be 6 × 36WS+IWR steel wire rope by 13 stocks altogether 265 steel wires form, this steel wire rope has the following advantages:
1) steel wire diameter is large, intensity is high and zinc-plated, and steel wire rope steel wire used has larger diameter (more than 3.00mm), and all intensity of steel wire, more than 1960MPa, breach a production difficult problem for high strength, large gauge zinc-coated wire.
2) have the feature of high disrumpent feelings value, whole rope rupture pull force, more than 2350KN, can bear larger load.
3) there is very high corrosion resistance, owing to have employed hot dip galvanizing process process, the requirement that all steel wire zinc layer weights are all zinc-plated more than A level in GB/T8918-2006, highly corrosion resistant ability that steel wire rope sling is standby, effectively can prevent immersion corrosion in seawater, high life, is particularly useful for the important events such as offshore drilling platforms anchor line.
Accompanying drawing explanation
Fig. 1 is the cross sectional representation of the utility model embodiment steel wire rope.
In figure, 1. steel wire rope outer layer strand, 2. steel core rope outer layer strand, 3. steel core rope central strand, 4. outermost layer steel wire, the 5. large silk of time skin, the 6. little silk of time skin, 7. steel wire of internal layer, 8. core wire, 9. steel core rope outer layer strand outer silk, 10. steel core rope outer layer strand central hair, the outer silk of 11. steel core rope central strand, 12. steel core rope central strand central hairs.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The innovative point of the utility model offshore drilling platforms anchor line is: anchor line (steel wire rope) high strength takes into account thick zinc coat.
Steel wire rope antiseptic property is by carrying out galvanizing to realize to all steel wires of composition steel wire rope; after galvanizing; one deck zn-fe alloy layer can be formed at Fe matrix surface; and form one deck zinc layers at zn-fe alloy layer outer surface, in corrosive medium, zinc layers can form galvanic cell with Fe and C in steel wire matrix; produce electrochemical reaction; thus making zinc layers preferentially react and consume, protection Fe matrix is not corroded, and belongs to the cathode protection method of sacrificial anode.This anticorrosion ability mainly relies on zinc layer weight and thickness to realize, and zinc layer weight is large or thickness large, and corrosion resistance is just high, and zinc layer weight is little or thickness is little, and corrosion resistance is just low.
With reference to Fig. 1, the structure expression of the utility model offshore drilling platforms anchor line is 6 × 36WS+IWR (6 × 7+1 × 7), wirerope diameter 58mm, by six roots of sensation diameter be the steel wire rope outer layer strand 1 of 18.89mm, the steel core rope central strand 3 of six roots of sensation diameter to be the steel core rope outer layer strand 2 of 7.30mm and diameter be 8.48mm forms
Steel wire rope outer layer strand 1 profile is round, structural representation is 1-7-7+7-14, be made up of 36 zinc-coated wires, concrete structure is: around a core wire 8, twisting has compound steel silk successively, i.e. seven steel wire of internal layer 7, spaced seven outer little silks 6 and seven outer large silk 5,14 outermost layer steel wires 4 successively.Steel wire rope outer layer strand 1 on strander once twisting complete.
Steel core rope outer layer strand 2 profile is round, and structural representation is 1-6, and be made up of seven zinc-coated wires, concrete structure is: around a steel core rope outer layer strand central hair 10, twisting has the outer silk 9 of (1 layer) six roots of sensation steel core rope outer layer strand.Steel core rope outer layer strand 2 on strander once twisting complete.
Steel core rope central strand 3 profile is round, and structural representation is 1-6, and be made up of seven zinc-coated wires, concrete structure is: around a steel core rope central strand central hair 12, twisting has the outer silk 11 of (1 layer) six roots of sensation steel core rope central strand.Steel core rope central strand 3 on strander once twisting complete.
The all stock profiles of steel wire rope are circle, the method for expressing of steel cord structure, stock structure is the method for expressing adopting national Specification " steel wire rope-term, mark and classification ", such as ZAA6 × 36WS+IWR (6 × 7+1 × 7), IWR wherein represents wire rope core, is the concrete expression of steel core rope structure in bracket.
The preparation method of above-mentioned 6 × 36WS+IWR (6 × 7+1 × 7) structure steel wire rope is:
First required steel wire is carried out galvanizing process, steel wire after the assay was approved, be twisted into stock, steel core rope outer layer strand 2 and steel core rope central strand 3 are first twisted into the steel core rope that diameter is 22.70mm on crank closer, again six roots of sensation steel wire rope outer layer strand 1 is twisted into the steel wire rope that diameter is 59.47mm together with steel core rope, before becoming rope, outer layer strand is through predeformation, six roots of sensation steel wire rope outer layer strand 1 and steel core rope centered by steel wire rope cross-section center line helically line be wound around, realize the manufacture of 6 × 36WS+IWR, diameter 58mm steel wire rope.
