Leg retainer for marine working platform

Abstract

Abstract PURPOSE:To charge proper partial loads on both a lift mechanism and a leg- retaining mechanism, by detecting the load of pinion and a stopper fitted on the rack of a leg, and by rotating the pinion so that the ratio of both the loads may come to a specified value. CONSTITUTION:On a leg retainer form a marine working platform, a distortion gauge is fitted on the lifting rod 17 of the casing 15 of a pinion shaft 20 and a stopper 14, and torque applied to a pinion 7 and the stopper 14 is measured. Then, the extending degree of a oil-pressure cylinder 25 is regulated by a controller so that the ratio of both the loads may come to a specified value. Then, by a rack 27 set on the rod 26 of the oil-pressure cylinder 25, the pinion 7 is rotated via an electromagnetic clutch 22, a reduction gear 9, and the like, and both the loads are set to be of a specified value. As a result, proper partial loads are charged on both a lift mechanism and a leg-retaining mechanism, and the capacity of each mechanism can be minimized as needed.
