Abstract
The invention discloses a steel wire rope for a crawler crane and a production method thereof. The steel wire rope comprises a center strand, a fine rope strand, rough rope strands and outer layer strands, wherein the rough rope strands symmetrically wrap and twist the center strand; the fine rope strand is positioned in an outer clearance of two adjacent rope strands; the outer strands symmetrically wrap and twist the outermost side of the steel wire rope; and steel wires of the outer layer strands are connected in a surface contact shape and twisted together. In the production method, the steel wire rope can be cold pulled by a die to change the shapes of the steel wires in the outer layer strands, so that the steel wires in the rope strand is in a surface contact shape and is combined with the center strand, the fine rope strand and the rough rope strands. Since the structures of the outer layer strands are extruded by the die to be in a surface contact shape, the effective area of metal of the steel wire rope can be improved; compared with the 35W*7 steel wire rope with the same specification and strength, the fracture tension of the steel wire rope of the invention is improved by 22 percent; and when in use, the steel wire rope of the invention has large contact area with a winch and a sliding wheel, improved wear resistance and better rotation resistance.
Description
Technical field
The present invention relates to a kind of steel wire rope and preparation method thereof, specifically refer to steel cable for crawler cranes and preparation method thereof.
Background technology
At present, the multiplex 6 * 29Fi+IWR of crawler crane, 35W * 7 structure class steel wire ropes, these two kinds of steel wire ropes belong to linear contact lay wire rope, also are round-strand ropes, and national standard requires the rupture pull force coefficient of steel wire rope to only have 0.36.Because at present the handling weight of crawler crane is increasing, requires the minimum breaking force of load-bearing wires rope increasing, if select the round-strand rope of said structure, then wirerope diameter is too thick, and the design of crawler crane is brought certain difficulty.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of rupture pull force high, the steel cable for crawler cranes of wear-resisting, anti-extruding.
The technical scheme that solves the problems of the technologies described above is:
Steel cable for crawler cranes, comprise central strand, thin substrand, thick substrand and outer layer strand, described thick substrand wraps symmetrically twists with the fingers described central strand, and described thin substrand is positioned at the external series gap of adjacent two thick substrands, and described outer layer strand is wrapped symmetrically and twisted with the fingers in the steel wire rope outermost; Be face contact shape between the steel wire of described outer layer strand and connect, and be twisted together.
Outer employing face contact thigh, substrand and central strand adopt the line contact, make the rupture pull force of rope improve wear-resisting, anti-extruding.
Further be improved to, be line contact shape between the steel wire of described central strand, thin substrand and thick substrand and connect, and be twisted together.
Moreover, the core wire cross section of described outer layer strand is approximate regular hexagon shape, 6 section of steel wire of the skin of described outer layer strand are approximate trapezoid shapes and connect into ring by trapezoidal side edges, the trapezoidal end face of described 6 steel wires is connected with six contacts of described core wire respectively, the trapezoidal bottom of described 6 steel wires towards outside.
Moreover described central strand comprises core wire rope, 18 thick wires and 6 finer wires; 6 described thick wires wrap symmetrically twists with the fingers described core wire, and 6 described finer wires are positioned at the external series gap of adjacent two thick wires, and 12 described thick wires wrap symmetrically to be twisted with the fingers in the central strand outermost.
Moreover described thick substrand comprises core wire, 10 finer wires, 5 middle finer wires and 10 thick wires; 5 described finer wire bags are twisted with the fingers described core wire, and its outer staggered bag is twisted with the fingers and is provided with 5 middle finer wires and 5 finer wires, and 10 described thick wires wrap symmetrically to be twisted with the fingers in thick substrand outermost.
Moreover described thin substrand comprises core wire and 6 cover wires; Described 6 cover wires wrap the sth. made by twisting core wire symmetrically.
Simultaneously, the present invention also provides the preparation method of succinct, the easy to operate above-mentioned steel cable for crawler cranes of a kind of technique.
The technical scheme that solves the problems of the technologies described above is:
When the production outer layer strand, carry out the (cold-)drawn (steel)wire rope with mould, change wire shape in the outer layer strand, make the interior steel wire of rope strand be face contact shape, then close rope with central strand, thin substrand and thick substrand.
Because the structure of outer layer strand is face contact shape through the mould extruding, improved steel wire rope metal effective area, the 35W of contrast same size, intensity * 7 breaking force of rope have improved 22%, and the contact-making surface with elevator, pulley is large in use, ABRASION RESISTANCE improves, and rotation resistance is better.In use, the steel wire rope of this kind structure has stronger ABRASION RESISTANCE, crush resistance and resistance to shock loads performance, and can improve more than 20% service life.
