| description | The invention relates to an assessment method of a whole-course real-time service life of a lifting steel wire rope of a crane. The invention mainly solves technical problems that whole-course real-time tracking and service life assessment to the lifting steel wire rope are not available and quick early warning cannot be carried out timely. A technical scheme in the invention is that the assessment method includes following steps: (1) collecting real-time operation data of the crane; (2) sectioning the whole lifting steel wire rope on the basis of a multiplying ratio of a lifting pulley block; (3) calculating a tensile force on each section of the lifting steel wire rope under three situations of a lifting mechanism; (4) establishing a mechanical model of the tensile force on each section of the lifting steel wire rope during a whole travelling process; (5) calculating a stress in each section of the lifting steel wire rope; (6) performing statistical analysis to real-time stress change of each point; (7) calculating a service life of an evaluation point in each section of the lifting steel wire rope; (8) evaluating a whole-course service life of the lifting steel wire rope; and (9) performing early warning to the lifting steel wire rope. |
