Method for control of the chain drive mechanisms of underground working machines, especially chain scraper conveyors, and a chain scraper conveyor

摘要

The invention relates to a method for the control of the chain drive mechanisms of underground working machines and a correspondingly equipped chain scraper conveyor. In chain scraper conveyors with a large distance between the main and auxiliary drive stations, e.g. a distance of more than 400 m, a chain breakage in the bottom run or a shaft breakage can arise, which can be traced back to vibration phenomena in the chain. The invention proposes to filter out a detection signal (Serk), representative of the currently arising vibrations of the chain (1), from the operating data of the main and auxiliary drives (I, II) by means of a detection device (34), and to take this to an active suppressor, which generates a time-variable control signal (Schwingung) in accordance with a suppressor function, with which, in the frequency range of the vibration of the chain for the closing pressure adjustment of a multiple disc clutch (6) of at least one drive unit for the suppression of vibration by the abstraction of energy from, or the introduction of energy into the chain (1).
