The invention discloses a push block composite locking type quick-connecting-type drilling riser connector. The connector is characterized in that a ring groove is formed in the excircle of a male joint and provided with multiple lock blocks circumferentially, the inner wall of each lock block is provided with a ring tooth correspondingly meshed with the ring groove while the outer wall of the same is in driving connection with a driving ring, the circumference of the driving ring is provided with driving holes radially, six uniformly-distributed curved surface grooves are formed in the middle of the excircle of the driving ring, profile of each curved surface groove is an offset centrifugal-type curve, cross section of each curved surface groove is a circular arc, six uniformly-distributed curved surfaces are arranged on the inner circumference of the driving ring, profile of each curved surface is an offset centrifugal-type curve, one ends of the curved surface grooves and the curved surfaces are close to axis while the other ends of the same is away from the axis, six uniformly-distributed fan-shaped grooves are formed in a convex edge of the upper end face of a flange of a female joint circumferentially, a lock block is arranged in each fan-shaped groove, and an offset centrifugal-type curved surface is processed on the outer wall of each lock block. The push block composite locking type quick-connecting-type drilling riser connector has the advantage that the lock blocks are large in load-bearing area, high in load-bearing capability and safe and quick in composite locking.
Description
technical field [0001] The invention belongs to the technical field of offshore oil drilling and production equipment, and relates to a push block composite locking quick-connect type drilling riser connector. Background technique [0002] Marine drilling riser (hereinafter referred to as the riser) connector is an important connection device among the riser equipment. kinds of uses. [0003] Existing riser connectors usually have thread type, flange bolt type, push claw lock block type, etc. The thread buckle connector is suitable for shallow water, and the flange bolt type is suitable for deep water, with reliable connection and large bearing capacity, etc. The disadvantage is that the installation and disassembly are time-consuming and laborious, and the work efficiency is low; compared with the flanged joint, the push-claw lock block joint has a relatively fast connection speed, but it still needs to drive six bolts when connecting, and the operation is still troublesom...
