Abstract

The invention discloses a method for preventing a lifting system from impact and vibration. The method includes: acquiring the weight of articles in a lifting container; acquiring preset lifting system basic parameters; determining a fundamental wave vibration period of a lifting rope while the lifting system starts according to the weight of the articles in the lifting container and the lifting system basic parameters; determining a time varying simulation parameter of acceleration in a lifting process, of the lifting system according to the fundamental wave vibration period and preset lifting system calculation parameters; and lifting the lifting container according to the determined time varying simulation parameter of acceleration. In addition, the invention also discloses a device for preventing impact and vibration of a lifting system.

Description

technical field [0001] The invention relates to a lifting system, in particular to a method and device for preventing impact vibration of the lifting system. Background technique [0002] According to the existing start-up method of a large-scale lifting system, in the process of re-starting the lifting after reloading objects in the lifting container of the lifting system, the lifting container is usually lifted by setting fixed and constant acceleration time-varying simulation parameters. As a result, when the amount of load added to the lifting container changes, the time-varying simulation parameters of the acceleration cannot be adjusted in time according to the change of the weight parameter, which will cause shock vibration to the lifting system, which will have a negative impact on the lifting system. And its power transmission device causes greater adverse effects, and even causes equipment damage, which is not conducive to production safety. Contents of the inven...
