Example Embodiment

[0026] The technical solution of the present invention will be described in detail below with reference to the drawings.

[0027] Such as figure 1 As shown, the wear-resistant and soft crane wire rope model is 6×K36WS+6PPF+IWRC—￠28mm. Seen from the cross section, its structure includes two layers of inner and outer layers. The inner layer is composed of six inner strands 2 (￠3.45mm). The layer is composed of six outer strands 4 (￠9.2mm), and also includes a central strand 1 (￠5.3mm). The six inner strands 2 are evenly coated on the circumference of the central strand 1, and the inner strands 2 are The central strand 1 is in surface contact, and between the inner layer and the outer layer, there is a filler strand 3 (￠2.8mm), and the filler strand 3 is between the inner layer 2 and the outer layer 4 Surface contact.

[0028] Among them, such as figure 2 As shown, the central strand 1 is a high-strength polyester fiber rope composed of more than 1000 spirally rotating polyester fib...

Abstract

The invention relates to a steel wire rope used for a crane and a manufacturing method of the steel wire rope. The space between an inner layer and an outer layer is filled with a high strength polyester fiber rope, friction among metal strands is reduced, the polyester fiber rope further has the oil storage effect, the lubrication action can be achieved in the using process, and meanwhile the steel wire rope also has the wear-resistance advantage. A central strand is also composed of the high strength polyester fiber rope, so that in addition to the characteristic, the steel wire rope used for the crane can further have the advantages that the number of steel wires is small, the steel wire contact state is relatively stable, and the steel wire rope is soft.

Description

technical field [0001] The invention relates to the technical field of engineering materials, in particular to a steel wire rope for a crane and a manufacturing method thereof. Background technique [0002] The wire rope is an important part of the crane. At present, ordinary wire contact wire ropes are used, such as 6×29F-IWRC, 6×31WS-IWRC, 6×36SW-IWRC, 6×K31WS-IWRC, 6×K36SW-IWRC and other series products, there are The steel wire rope is hard, not strong in wear resistance, poor in flexibility or short in service life, which in turn affects the hoisting weight and safety of the crane. Contents of the invention [0003] In order to solve the technical problems in the prior art, the invention provides a steel wire rope for cranes with good wear resistance, high flexibility and long service life. [0004] Technical effect of the present invention is realized through the following technical solutions: [0005] A steel wire rope for a crane, comprising an inner layer and an...
