Extrusion-resistant and fatigue-resistant steel wire rope for rotary digging machine

Abstract

The invention discloses an extrusion-resistant and fatigue-resistant steel wire rope for a rotary digging machine. The extrusion-resistant and fatigue-resistant steel wire rope comprises a central strand, outer strands and main strands, wherein 6 outer strands are uniformly wrapped and twisted outside the central strand, and 6 main strands are uniformly wrapped and twisted outside the outer strand; the central strand and the outer strands all adopt a Warrington type structure, a central steel wire is respectively arranged at the centers of the central strand and the outer strands, and 6 steelwires are arranged outside the central steel wire, and are used for wrapping and twisting the central steel wire; the main strands adopt a Warrington-Seale type combined structure, a central steel wire is arranged at the center of each main strand, 6 steel wires which are uniformly wrapped and twisted outside the central steel wire serve as a first layer, 12 steel wires which are uniformly wrapped and twisted outside the first layer serve as a second layer, and 14 steel wires which are uniformly wrapped and twisted outside the second layer serve as a third layer; and the respective strands are in line contact. The extrusion-resistant and fatigue-resistant steel wire rope for the rotary digging machine, disclosed by the invention, has the advantages of extrusion resistance and fatigue resistance.

Description

technical field [0001] The invention relates to a steel wire rope, in particular to a steel wire rope for a rotary excavator with extrusion resistance and fatigue resistance. Background technique [0002] At present, steel wire ropes with structures such as 6×19S, 6×29FI, 6×31WS, and 6×36WS are used on important mechanical equipment such as rotary excavators and pile drivers. Due to the harsh operating environment of this equipment, it is difficult to bear heavy loads. It is easy to control, but the service life of the steel wire rope will be short due to problems such as poor flexibility, no pressure resistance, and poor fatigue of the steel wire rope. Contents of the invention [0003] The present invention aims to overcome the deficiencies of the above prior art and provide a novel structure anti-extrusion and fatigue-resistant rotary excavator [0004] Use a wire rope. [0005] The present invention solves technical problem and adopts following technical scheme: [...

AI Technical Summary

Problems solved by technology

[0002] At present, on important mechanical equipment such as rotary excavators and pile drivers, steel wire ropes with structures such as 6×19S, 6×29FI, 6×31WS, and 6×36WS are used. Because the operating environment of this kind of equipment is relatively harsh, it bears a heavy load and is difficult to control. It will lead to short service life of the wire rope due to problems such as poor flexibility, pressure resistance, and poor fatigue of the wire rope.
