The invention discloses a hydraulic drive type steel wire rope guide flat tail rope swing controlling device and method which are suitable for steel wire rope guides. A flat interference swing restraining device is adopted to rotate at 90 degrees, the flat interference swing restraining device can limit a tail rope in the radial direction when being extended, and the flat interference swing restraining device can retract to the side face of a guide beam when being withdrawn. Hydraulic drive is adopted to enable limiting shafts to horizontally rotate and gradually clamp and limit the tail ropefrom the two sides of the rope tail. Limiting hydraulic cylinders are provided with tension springs, the top ends of the limiting shafts are provided with counter weights, under the power failure emergency working condition, the limiting shafts are made to recover to the release state under the action of pull force of the tension springs, a supporting shaft rotates to the side face of the guide beam under the gravity action of the counterweights, interference in operation of a hoisting container is avoided, then multi-point guide and control of swing of the overhung section flat tail rope areconducted, and swing of the tail rope is fundamentally limited to a great extent. The hydraulic drive type steel wire rope guide flat tail rope swing controlling device is novel in structure, reliablein performance and guarantees safe operation of a vertical shaft lifting flat tail rope counterweight balance system.
