Embodiment Construction
[0020] Below in conjunction with accompanying drawing, the rope body twisted according to 6 strands of steel rope is example, the specific embodiment of the present invention is described in further detail:
[0021] Such as figure 1 , as shown in 2, the double-safety pressed steel rope includes a rope body 2 formed by rotating and interlaced twisting of six strands of steel rope 1 and lifting rings 3 at both ends of the rope body. The lifting ring 3 is inserted through the free end 4 of the six strands of steel rope After the body is twisted, the six strands of steel rope are interspersed back and forth three times at the cross section of the insertion joint, and the insertion is completed by using a steel needle to pry open the strands. After three insertions, the free ends of each strand of steel rope are adjacent to each other in the six strands of steel rope The 6 gaps formed between the steel ropes pass through and are twisted together with the rope body 2 of the original...

The present invention relates to a double-insurance pressed steel rope. The double-insurance pressed steel rope comprises a rope body formed by a plurality of strands of the steel ropes in a rotatingstaggered twisting mode, and flying rings at the two ends of the rope body; each flying ring is formed by enabling the free ends of the plurality of strands of the steel ropes to interpenetrate through the rope body for at least two times; the interpenetrating joints of the plurality of strands of the steel ropes are sleeved with aluminum alloy joints, and the interpenetrating joints are pressed and reinforced by the aluminum alloy joints. The free ends of the steel ropes are twisted into the rope body in an inverted mode to form the flying rings, and each strand of steel rope performs three times of interpenetrating to achieve synchronous line contact friction with six strands of steel ropes, so that the bonding strength is high; the free ends are twisted into the rope body, and the freeends and the rope body are integrated through pulling force, so that the higher the pulling force in the inserting connecting position of the steel rope is under a stressed condition, the higher the safety coefficient becomes. By virtue of the technical scheme, the effect of strengthening the steel rope safety factor is realized to ensure that the effect of the prepared steel wire rope sling is provided with a double-insurance function, and can be more widely applied to certain special environment operations.
Description
technical field [0001] The invention relates to the field of hoisting, in particular to double-safety pressed steel ropes for hoisting and a processing method thereof. Background technique [0002] Rigging is widely used in ports, electric power, steel, shipbuilding, petrochemical, mining, railway, construction, metallurgy and chemical industry, automobile manufacturing, engineering machinery, paper machinery, industrial control, logistics, large-scale transportation, pipeline auxiliary construction, sea rescue, Marine engineering, airport construction, bridges, aviation, aerospace, venues and other important industries. Steel rope is the most common sling. Steel rope is a force-bearing tool tied between the hoisting machinery and the object to be lifted. The steel wire rope plays the role of bearing the load, and its performance is mainly determined by the steel wire. The strength of the steel rope depends on the number of strands of steel wire in the steel rope and the ma...
