Design and Research of Double-Drum Winch for Lowering Mooring Anchor Chains

Abstract:

The designed double-drum winch is applied to the development of Liwan 3-1 gas field of the South China Sea for lowering mooring anchor chains, which is composed of motor, brake, reducer, front and rear drums, two-stage gear transmission devices, rack and base. There is an intermediate axle between two drums of the winch. On the intermediate axle there are two gears, a large one and a small one. The large gear installed on the intermediate axle goes into mesh with the pinion gear installed on the output shaft of reducer, and the small gear installed on intermediate axle meshes with the large gears installed on the front and rear drums separately. The speed of rotate from the motor is sent to the two-stage gear transmission devices by the reducer, to realize two drums rotate simultaneously in the same direction. Compared to the double-drum winch of multi-motor synchronous drive, the designed double-drum winch can be more reliable and avoid the difficult technical problems of multi-motor synchronous drive and control in a large extent.
