Embodiment Construction

[0114] As mentioned above, regular inspections of the running components in the lifting mechanism not only require high costs, but also cause failures in the running components of the lifting mechanism between two inspections, which will still lead to unplanned shutdowns, and The inspection time is long, and it is impossible to predict the remaining life of the running components in the lifting mechanism.

[0115] In the embodiment of the present invention, the running components in the lifting mechanism all correspond to the remaining life calculation values, and the influencing factors will affect the remaining life of the running components. Each running component has at least one influencing factor, and each influencing factor can be passed Real-time monitoring obtains its monitoring value, and by pre-constructing the corresponding relationship between the impact factor, monitoring value range, and life coefficient, the life coefficient corresponding to each impact factor c...

Abstract

The invention provides a prediction method and device for the residual life of an operation assembly in a lifting mechanism, computing equipment and a computer readable medium. The method comprises the steps that the residual life calculated value of a target operation assembly is obtained; determining at least one influence factor influencing the residual life of the target operation assembly; for each influence factor, executing the following steps: acquiring a monitoring value of the current influence factor; determining a monitoring value range in which the monitoring value of the currentinfluence factor is located according to a pre-constructed corresponding relationship among the influence factor, the monitoring value range and the life coefficient; obtaining a life coefficient corresponding to the current influence factor and the determined monitoring value range according to the corresponding relationship; and correcting the residual life calculation value by utilizing the obtained life coefficients to obtain a residual life prediction value of the target operation assembly. According to the scheme, prediction of the residual life of the operation assembly in the lifting mechanism can be realized.

Description

technical field [0001] The invention relates to the field of electromechanical equipment, in particular to a method, device, computing device and computer-readable medium for predicting the remaining life of a running component in a lifting mechanism. Background technique [0002] The lifting mechanism is one of the four core mechanical components of the electric shovel, and its main function is to transmit torque and lift the shovel. Since large hoisting mechanisms are not easy to maintain, unplanned downtime due to failure of operating components in the hoisting mechanism during operation will cause huge losses. [0003] In order to prevent the above problems, at present, the running components in the lifting mechanism will be maintained by regular spot inspection. During the spot check process, the running components in the lifting mechanism need to be checked one by one, and the running components with problems should be repaired. This method not only has high cost, but...
