Definitions

  • a stranded wire rope In the construction of a stranded wire rope a plurality of steel wires are laid in various formations or constructions to form a strand and a number of strands are laid to form a rope.
  • ferrous metals will oxidize in the presence of an aqueous solution of an electrolyte and that such oxidation can be prevented or retarded in a number of ways which can be physical or chemical.
  • the physical methods aim at coating the metal with a protective covering which resists penetration of moisture to the metal and one chemical method aims at establishing a balance between ferrous and non-ferrous metals in which the non-ferrous metal acts as a reducing agent and so prevents or delays oxidation of the ferrous metal.
  • Examples of such chemical protection are the association of metallic zinc or metallic aluminium with the ferrous metal.
  • a limiting factor in the galvanizing method of protection is that in service the zinc coating on the wire, in addition to chemical change, may be subject to abrasion so that the two influences act to reduce its effectiveness in protecting the ferrous metal.
  • the present invention provides a means for protecting the ferrous metal from corrosion and at the same time mitigates the limitations in the known method of using galvanized steel wire.
  • control element used throughout the description and claims refers to a metallic zinc element or a metallic aluminium element and the term foil" includes a wrapping or coating.
  • a wire rope strand comprises a plurality of steel wire components and at least one control element, said steel wire components and control element or elements laid in known manner to form a strand and said control element or elements so arranged in the strand that the steel wire components are conductively in contact with an associated control element, and the or each control element is surrounded by steel wire components.
  • a steel wire rope comprises a plurality of said strands laid in known manner to form a rope.
  • the steel wires may be galvanized steel wires.
  • At least one of the control elements is in the form of a wire.
  • One of the control elements may be in the form of a foil of metallic zinc or aluminium wrapped around a strand of steel wires between the outer layer and an adjacent inner layer of steel wires or a coating of metallic zinc or aluminium.
  • FIG. 1 is a section through a wire strand constructed according to the invention
  • FIG. 2 is a section through a wire strand of different formation to that of FIG. 1;
  • FIG. 3 is a section through a wire rope formed from strands of FIG. l;
  • FIG. 4 is a section through a wire strand of different construction to that of FIGS. I and 2;
  • FIG. 5 is a section through a wire strand of yet another construction.
  • FIG. 1 of the drawings 1 denotes generally a wire strand having king control element 2 of metallic zinc or aluminium in the form of a wire and a plurality of steel wire components 3 laid around the element 2 in known manner to form a strand.
  • a wire strand 1 is constructed similar to that of FIG. 1 except that the king element is formed by three metallic zinc or aluminium control 2 and wires twisted together to form a central strand.
  • Each steel wire component 3 is in contact with at least one of the metallic zinc control elements 2 and a plurality of strands 1 are laid in known manner to form a rope which may have a natural or synthetic core or an independent wire rope or strand core.
  • the strand or strands in the core may be formed with a metallic zinc or aluminium element or elements in accordance with the invention.
  • FIG. 3 illustrates the use of six strands l constructed according to FIG. 1 and laid to form a rope known as a 6 X 7 construction i.e. each strand in the rope is formed with seven wires, six of which are steel wires 3 laid around one control element 2. Six strands are used to construct the rope which has a fibre core 4. The six strands being laid around the core 4 in known manner.
  • control element 2 in each strand is enclosed or encased by the steel wire components and is therefore protected from abrasion when in use but is subject to chemical change by oxidizing and in so doing prevents or retards oxidation of the steel wire components.
  • the core 4' may be formed by a wire rope construction in which each strand has at least one control element.
  • control element can be on the outer surface of the core since it is not subject to abrasion in use and may be in the form of a foil wrapped around the core rope.
  • the core rope may be dipped in a zinc bath to form a zinc coating thereon or the core rope may be formed in conventional manner using galvanized steel wires.
  • the king wire is a steel wire component 3 and has a first layer of six wires around the king wire, three of which are control elements and three are steel wire components 3 laid alternatively and an outer layer of twelve wires each of steel wire components 3.
  • 6 X 19 construction rope which may have a core of fibre rope or of steel rope or strand as previously described.
  • FIG. 5 illustrates a larger diameter strand construction which has 37 wires.
  • the king wire is formed from a wire control element 2, an inner layer Sis formed in known manner from steel wire components 3, an intermediate layer 6 is formed of steel wire components 3 in known manner on the inner layer 5 and a control element in the form of a foil 7 is formed around the intermediate layer 6.
  • the foil 7 may be in the form of a zinc or aluminium foil wrapped around the intermediate layer 6 or the strand so formed may be dipped in a zinc bath to form a coating around the intermediate layer.
  • An outer layer 8 of steel wire components 3 is then formed around the foil 7.
  • the strands so formed are laid to form a rope.
  • 6 strands each having a king wire, an inner layer of six wires, an intermediate layer of twelve wires surrounded by a foil control element and an outer layer of 18 wires are laid to form a rope.
  • the rope may have a fibre rope or strand core or an independent steel wire rope or strand core constructed as previously described with reference to FIG. 3.
  • the foregoing are examples of strand constructions but the present invention is not to be considered as limited to these particular constructions as it will be seen that a variety of strand constructions are possible.
  • the number of control elements used in a strand construction depends on the number of steel wire components in the strand and the disposition of the control elements in relation to the steel wire components depends on the number of layers in a strand.
  • the steel wire components are laid so as to be conductively in contact with a control element.
  • the element may be substituted by a zinc or an aluminium element or where there is more than one element, zinc and aluminium elements may be used.
  • the foil may be of aluminium while the king wire is metallic zinc or vice versa.
  • a second set of warps of 6 X 7 construction but made according to this invention with ungalvanized steel wires surrounding a zinc wire was then fished by the same boat in the same conditions.
  • each strand Preferably sufficient zinc wires are included in each strand to ensure that when the strand is constructed in known manner the steel wires are each conductively in contact with a zinc wire and the zinc wire is so located in the strand as to be protected by the steel wires from abrasion when in use.
  • Two or more zinc wires may be used instead of a single zinc wire and one or more zinc wires may form the core of a strand or rope.
  • control wire elements may be located between the outer layer and the adjacent inner layer or control wire elements may be spaced in the layer adjacent to the outer layer.
  • a foil of zinc or aluminium may be wrapped around the outer surface of the layer adjacent the outer layer.
  • the zinc wire or foil used in the above examples may be substituted by a metallic aluminium wire or foil or the strand may be constructed using a zinc wire or wires and upon aluminium foil depending on the number of steel wires contained in the strand.
  • zinc or aluminium elements in a strand need not be limited to protecting ropes or strands made from ungalvanised steel wire but can be used in conjunction with galvanised steel wires, particularly in applications where conditions effecting corrosion are more than normally severe.
  • a wire rope strand comprising a plurality of steel wire components and at least one control element, said steel wire components and control elements laid in known manner to form a strand, said control elements so arranged in the strand that each steel wire component is conductively in contact with an associated control element which is surrounded by steel wire components, at least one of the control elements comprising a plurality of wire elements laid between two adjacent layers of steel wire components as an additional layer.
