Embodiment Construction
[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0040] see Figure 5-Figure 6 As shown, the embodiment of the present invention provides a high breaking force special-shaped strand steel wire rope, including:
[0041] Six strands and a rope core, the six strands are evenly twisted around the periphery of the rope core, and each strand is tangent to the rope core;
[0042] Each said rope strand comprises a high-strength strand core consisting of six steel wires with the same diameter, an inner layer wire and an outer layer wire closely surrounding the high-strength strand core, and the diameter of the inner layer wire is smaller than the outer layer wire The diameter of the layer wire, and each strand of the rope is formed by twisting the high-strength strand core, the outer layer wire and the inner layer wire; the high-strength strand core includes three parallel steel wire groups, and the...

The invention discloses a high-breaking-tension special-shaped-strand steel wire rope and a manufacturing method thereof and relates to the field of steel wire ropes. The steel wire rope comprises a rope strands and a rope core, the rope strands are uniformly twisted on the periphery of the rope core, and each rope strand is tangent to the rope core; each rope strand comprises a high-strength strand core composed of six steel wires identical in diameter, an inner-layer wire and an outer-layer wire, the inner-layer wire and the outer-layer wire closely surround outside the high-strength strandcore, the high-strength strand core comprises three parallel steel wire groups and is formed by twisting the same in one time, and each parallel steel wire group is formed by twisting two steel wiresidentical in diameter in one time. The steel wire rope is more stable and reliable in structure, and quality defects of high triangular-strand steel wire rope stress, poor strand wire compactness andstrand edge turning are overcome.
Description
technical field [0001] The invention relates to the field of steel wire ropes, in particular to a special-shaped strand steel wire rope with high breaking tension and a manufacturing method thereof. Background technique [0002] Triangular strand steel wire rope is widely used in coal, metallurgy, nonferrous metals and other industries due to its significant advantages such as large contact area with matching wheel groove, high breaking force value and long service life. It is an irreplaceable steel wire rope variety and has always been favored by producers and users of great importance. [0003] The existing triangular strand steel wire rope is formed by tightly fastening 6 triangular strands with a certain helical shape around the rope core. The so-called special-shaped strands mainly refer to non-round strands, generally triangular strands, oval strands and flat strands. Figure 1-Figure 4 Shows the cross-sectional view of the core of the current common triangular strand...
