ANCHOR WINCH Russian patent published in 2022 - IPC B63B21/00 B66D1/00 

FIELD: ships anchoring equipment.

SUBSTANCE: invention relates to equipment for anchoring ships, namely to anchor winches. The anchor winch consists of a frame, a drive, a drive shaft, a drum with a clutch and an anchor rope wound around it, and an anchor release mechanism. The drive is made in the form of two motor-reducers mounted on both sides of the drive shaft on the frame, the gearboxes of which are kinematically connected to the drive shaft. The clutch is configured to transmit torque from the drive shaft to the drum, and on the opposite side of the mentioned hook stops, a drum return mechanism is mounted. The armature reset mechanism is made in the form of an auto-reset drive based on a separate motor-reducer with the ability to control the clutch disengagement, for which an eccentric with a roller at its end is mounted on the shaft of the said drive, which, when the armature auto-reset drive shaft is rotated, comes into interaction with the side wall of the drum, leads it into translational motion along the drive shaft and opens the clutch. The drum return mechanism, when the auto-reset drive eccentric is turned in the opposite direction, returns the drum to its original position and closes the clutch. On the side opposite to the eccentric, on the auto-reset drive shaft, a pressure sleeve is mounted, made with eccentricity to interact with limit switches of the extreme positions of the drum. The auto reset drive, traction gearmotors and limit switches are connected to the control board, to which the gearmotor controls are also connected.

EFFECT: increased reliability and speed of the anchor winch.
