Description
Technical field
The present invention relates to the thick diameter wire rope of a kind of multilayer multifibres, particularly a kind of stability, pliability, the good thick diameter wire rope of multilayer multifibres of antitorque commentaries on classics Performance And Reliability belong to the steel wire rope product technique field.
Background technology
Thick diameter wire rope is meant than general wirerope diameter coarse-wire rope more; Be generally to cast anchor in the ocean, macrotype platform drilling well, large-scale lifting use, and belongs to the very large a kind of consumable material of use amount, mainly on boats and ships and large-scale hanging device, pull and promote; Directly influence operating efficiency and safety the service life of steel wire rope; The service life of ordinary steel rope is shorter, and mostly the thick diameter wire rope of this type of high-performance is import, and cost is higher; Therefore, the thick diameter wire rope of development high-performance has very important significance.At present, common thick diameter wire rope comprises rope strand, wire rope core; Said rope strand is 6, arranges along the excircle of wire rope core according to the angle of 60 ° of five equilibriums; Said rope strand comprises core wire, steel wire of internal layer group and cover wire group; Said core wire is one group, and core wire is arranged on the center of rope strand, and the steel wire of internal layer group is positioned at the periphery of core wire, and the cover wire group is twisted with the fingers the periphery built in the steel wire of internal layer group; Said steel wire of internal layer group is that point contacts with the cover wire group.Said steel wire of internal layer be one group be arranged on core wire around, be circle; The profile of said cover wire also is circular; Said cover wire is one group, is arranged on the periphery of steel wire of internal layer; Said rope strand is 2 layers of sth. made by twisting system, and the steel wire diameter of employing is thicker, and poor, antitorque commentaries on classics performance of filament strength and pliability are relatively poor; Cause in use; Receive extruding, reverse or when crooked, the steel wire in the rope strand is prone to take place quick-fried disconnected phenomenon that also produce dangerous reduction of service life.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of life-span length, stability, pliability, the good thick diameter wire rope of multilayer multifibres of antitorque commentaries on classics Performance And Reliability.
Technical solution of the present invention is achieved in that the thick diameter wire rope of a kind of multilayer multifibres, comprises rope strand, wire rope core; Said rope strand is 6, arranges along the excircle of wire rope core according to the angle of 60 ° of five equilibriums; Said rope strand comprises a strand core, ground floor steel wire rope group, second layer steel wire rope group, compound steel silk rope group, the 4th layer of steel wire rope group, layer 5 steel wire rope group, layer 6 steel wire rope group; Said strand of core is made up of one group of steel wire rope; The thigh core is arranged on the center of rope strand, and ground floor steel wire rope group is positioned at the periphery of strand core, and second layer steel wire rope group is twisted with the fingers the periphery built in ground floor steel wire rope group; Compound steel silk rope group is twisted with the fingers the periphery built in second layer steel wire rope group again; The 4th layer of steel wire rope group twisted with the fingers built in the periphery of compound steel silk rope group again, and layer 5 steel wire rope group is twisted with the fingers built in the periphery of the 4th layer of steel wire rope group again, and layer 6 steel wire rope group is twisted with the fingers the periphery built in layer 5 steel wire rope group again; Each adjacent wires rope is tangent to each other in the said rope strand.
Preferably, said rope strand is made up of 115 different-diameter steel wire ropes, and the adjacent wires rope is tangent mutually.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
The thick diameter wire rope of multilayer multifibres of the present invention; Because the rope strand shape is multilayer, multifibres, dotted line contact, circular; Said particular manufacturing craft and the equipment system of twisting with the fingers utilized in process of production forms; And through rational wire distribution technology, per sharely form by 115 different-diameter steel wires, adopt 6 layers to twist with the fingers system; Thereby the problems such as quick-fried silk that can prevent that wire distribution in the production process is difficult, occur that pliability is poor in production difficulty height and the use, monofilament tensile strength difference and antitorque commentaries on classics poor performance cause; And then can obtain steel wire rope overall flexibility preferably; Monofilament tensile strength and antitorque commentaries on classics performance; Make whole rope design, produce, detect more convenient, improve the stability and the high reliability of steel wire rope, prolong product service life.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
Accompanying drawing 1 is the sectional view of the thick diameter wire rope of multilayer multifibres of the present invention;
Accompanying drawing 2 is the cross section enlarged drawing of the rope strand of the thick diameter wire rope of multilayer multifibres of the present invention;
