Artificial island with adjustable columns - has opposite column rack pinions in housings coupled by reaction rods

摘要

The artificial island comprises a pontoon and a number of columns adjustable in the vertical direction in relation to it. Each column has on two or more opposite edges racks with which pinions of lifting drive mechanisms on the pontoon mesh. The two opposite pinions (7) in a pair run in bearings in housings (3, 4) coupled together by a hinging reaction rod (17). Each housing is pivot-mounted in a link of a linkage secured to the pontoon, and the axis of this pivot mounting coincides with that of the pinion. The linkage can incorporate several drive units, coupled together by standard links. Each reaction rod is at the level of the centre of the links between.
