METHOD OF CONTROL CHAIN-DRIVEN DEVICES OF UNDERGROUND MACHINES, PARTICULARLY, CHAIN SCRAPER CONVEYORS AND DESIGN OF CHAIN SCRAPER CONVEYOR

摘要

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 S_Erk by means of detecting device from operation data of main and auxiliary drives which is essentially appearing actual circuit oscillations T_schwingung and to feed it to active damper. The latter, depending on detection signal S_Erk according to damping function, generates control signal S_Tilgung changing in time. Changing of regulated value, for instance, S_soll 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
