Abstract

The invention relates to the technical field of engineering machinery, and discloses a judgment method and a judgment device for judging the health condition of mechanical equipment, and engineering machinery. The judgment method comprises the following steps of: monitoring whether induced electromotive force is generated in an induced electromotive force generation module or not, wherein all or part of the induced electromotive force generation module is located in a magnetic field generated by a magnetic field generation module, and the induced electromotive force is generated on the basis that the magnetic field generation module adsorbs abrasive dust existing in oil flowing through the magnetic field in the mechanical equipment through the magnetic field; according to the monitoring result, judging whether the abrasive dust exists in the oil liquid or not; and under the condition that the abrasive dust exists in the oil liquid, judging the abrasion state of a part generating the abrasive dust in the mechanical equipment and/or the working state of the mechanical equipment according to the generated induced electromotive force and/or the number of the abrasive dust. Therefore, the health condition of the mechanical equipment is judged.

Description

technical field [0001] The invention relates to the technical field of construction machinery, and in particular, to a determination method and a determination device for determining the health status of mechanical equipment, and construction machinery. Background technique [0002] The boom rotation mechanism is a hydraulic direct drive mechanism, which converts the translational motion of the piston in the mechanism into the axial rotation of the boom through hydraulic drive. Due to the long-term operation of the boom rotating mechanism under complex working conditions such as heavy load, the continuous meshing between the gears leads to surface wear, especially when the rotating mechanism is repeatedly started and stopped, shock vibration occurs, which aggravates the wear between the gears. Long-term wear and tear will increase the gap between the gears in the mechanism, making it unable to move smoothly, and eventually causing the structure to be scrapped. How to detect...
