The articulation of the type forming a universal joint of a cardan joint for a column articulee of a structure of the operation of the sea bottom

摘要

P the invention relates to an articulation of the type forming a universal joint. / p & & p & the block 2 of the gasket 1 is articulated along two perpendicular axes xx ', yy', each supported by two cradles 3a, 3b, 7a, 7b. On the basis of the upper and lower faces of the block 2 extend respectively two gantries 20, 20 'along said axes. The free ends of the frames 20, 20 ′ are respectively integral with two seals of twist 16, 16'. These joints are respectively connected to one end to the two associated cradles and connected together by a rigid connection duct 30. Such a conduit makes it possible to connect two rigid ducts, respectively, integral with the two assemblies connected by a joint of this kind. / p & & p & in particular, the invention applies to a column articulated to a structure of the operation of the sea bottom, in order to permit the passage of a plurality of conduits of the rigid connection between the column and its base. / p
