FIELD: mechanical engineering; mining machinery. ^ SUBSTANCE: invention relates to method of control of chain-driven devices of underground machines and to correspondingly equipped chain scraper conveyor. Proposed invention makes it possible to discriminate detection signal SErk by means of detecting device from operation data of main and auxiliary drives which is essentially appearing actual circuit oscillations Tschwingung and to feed it to active damper. The latter, depending on detection signal SErk according to damping function, generates control signal STilgung changing in time. Changing of regulated value, for instance, Ssoll is provoked by control signal in circuit oscillation frequency range. As a result, setting of closing pressure of plate clutch of at least one drive unit it provided to till oscillations owing to removal or supply of energy into circuit. ^ EFFECT: elimination of oscillations in underground machines with chain drive caused by cracks in lower run chain or wave destruction caused by chain oscillations. ^ 14 cl, 4 dwg |
