The invention relates to a steel wire rope for a nacelle and a manufacturing method thereof. The steel wire rope is in a seale type structure, the external surface of the steel wire rope is in a sector shape, and the steel wire rope comprises four upper strands and one synthetic fiber core, wherein the four upper strands are symmetrically twisted on the synthetic fiber core, and the sector surface is outward. The preparation method comprises the following steps: firstly, twisting a light-gage steel wire on one synthetic fiber core to form an initial lower strand, and sequentially and symmetrically winding a light-gage steel wire and a heavy-gage steel wire in a seale type on the outer layer of the initial lower strand to form the upper strand; then twisting four upper strands on one synthetic fiber core into a rope to form the product, namely, the steel wire rope for the nacelle; and extruding steel wire rope for the nacelle into a sector shape by two groups of orthogonal sizing tools during rope twisting. The four steel wire ropes with different shapes provided by the steel wire rope for the nacelle and the manufacturing method thereof of the invention have good rotation-resisting performance and basically realize no rotation of the steel wire ropes, a sector strand has a large contact surface with a pulley and good wear resistance, and by tightening a deformed steel wire rope, the breaking force is improved by one level compared with a round strand steel wire rope at the same level.
Description
technical field [0001] The invention relates to a steel wire rope and a manufacturing method thereof, in particular to a steel wire rope for a hanging basket and a manufacturing method thereof. Background technique [0002] Common steel wire rope 6×37 series for hanging baskets has the following defects: 1. The national standard stipulates that the breaking force coefficient is 0.319, and the breaking force is low. 2. The steel wire rope rotates by itself, which is not suitable for high heights. 3. The round strand steel wire rope is wear-resistant Sex is not good. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a steel wire rope for a hanging basket with good rotation resistance, fatigue resistance, non-slip, wear resistance and high breaking tension. [0004] The technical scheme that solves the above-mentioned technical problem is: [0005] The steel wire rope for the hanging basket includes 4 upper twi...
