TAPERED RAMP POSITIVE LOCK LATCH MECHANISM

摘要

A tool (27) lands a flowline connector (25) on a base and soft land the connector to a mandrel. After the tool lands on the base, the tool locks to the base and then pushes the connector the mandrel until it abuts and locks to the member. The tool (27) has at least one ring assembly (31, 33) with a number of dogs (47) per ring assembly. Each dog (47) moves in unison with a follower relative to a cam ring in a slot. The movement along the slot moves the dogs (47) radially and circumferentially relative to the cam ring (101). An actuator moves a follower ring (103) that slides relative to the cam ring (101) that moves the follower. Each dog (47) remains in contact with the cam ring (101) after moving radially inward because of protuberances on each dog that slides from a recess as the dog moves circumferentially and radially inward.
