METHOD OF CONTROLLING TRANSVERSE RESONANCE IN CATENARY PART, HOISTING WINCH CONTROL SYSTEM AND SHAFT DRUM LIFTING SYSTEM Russian patent published in 2019 - IPC B66B19/00 B66B1/00 B66B15/00 B66D1/48 

FIELD: lifting devices.

SUBSTANCE: present invention relates to a method of controlling transverse resonance in a catenary portion of a mine drum winch system (1) comprising a lifting winch drum (5) having a Lebus groove, head pulley (7), rope (9) having catenary part (9a) extending between drum (5) of hoisting winch and head pulley (7), and vertical section (9b) of rope, as well as cargo stand (11) attached to vertical section (9b) rope. Method includes a) determining current load of cargo stand (11), b) obtaining hoisting winch drum speed (5) of lifting hoist corresponding to first speed of cargo stand (11), c) determination of localization of transverse resonance along vertical section (9b) of rope, in which in catenary part (9a), when it is reached by load cage (11) with current load and at first speed, there is a transverse resonance, wherein localization of the transverse resonance is determined based on the current load and based on the speed of the hoisting winch, and d) reducing the first speed of the load stand in the speed reduction area, which includes localization of the transverse resonance.

EFFECT: this invention relates to lifting winch drum system (3) and mine shaft lifting hoist system (1).
