초록 ▼

A remotely operable vessel cover assembly used with a vessel. The cover assembly has a mounting rim secured to the vessel surrounding a circular opening and a circular cover to fit against the mounting rim. A force ring having a plurality of openings is attached to the cover. Connector pins are attached to and extend from the mounting rim and through a plurality of holes in the cover and the force ring. A lock ring is rotatably attached to the force ring and locks the extending heads of the connector pins to the force ring to restrain the cover in an initial position. A force actuator, disposed between the force ring and the cover, expands under fluid pressure to react against the cover forcing the cover against the mounting rim. Upper and lower ramps are connected to the periphery of the cover and a ramp ring respectively. The ramp ring, rotatably supported between the force ring and the cover, has lower ramps positioned to match upper ramps on the cover. The rotation of the ramp ring relative to the cover holds the cover against the mounting rim. A safety lock assembly is connected to the ramp ring to prevent unintended releasing rotation of said ramp ring relative to the cover.

A remotely operable vessel cover assembly used with a vessel wherein the vessel includes a lower, substantially horizontal opening and a mounting rim surrounding the opening, comprising: a plurality of connector pins extending from the vessel mounting rim; a cover having a perimeter sized to fit against the mounting rim to provide a closure for the vessel opening; means for receiving said connector pins having a first portion attached to said cover on a side of said cover opposite from the mounting rim, said first portion having openings through which said connector pins extend when said cover is in an initial position against the mounting rim; means for locking said connector pins to said first portion; means for the final positioning of said cover against the mounting rim, said final positioning means disposed substantially between said cover and said pin receiving means for moving said cover and said pin receiving means for moving said cover from the initial position into a desired final position against the mounting rim and for prestressing said connector pins interlocked with said pin receiving means; means for locking said cover in the final position, said cover locking means disposed substantially adjacent said final positioning means between said cover and said pin receiving means, movable relative to said cover from an initial unlocked position to a final locking position for locking said cover in the desired final position in which said connector pins are prestressed; and a safety lock assembly connected to said cover locking means to prevent accidental unlocking of said cover form the final locking position; wherein said safety lock assembly comprises: a housing having a first end, a midportion, and a second end with a bore extending through said housing, said midportion of said housing forming an enlarged cavity having substantially flat upper and lower surfaces, said substantially flat lower surface including a plurality of teeth and said second end of said housing attached to a force ring; a connector rod having a first end and a second end, said first end pivotably connected to a ramp ring assembly and said second end slidably extending through the bore in said first end of said housing; a gripper pivotably connected to said second end of said connector rod, said gripper having a plurality of teeth capable of engaging said housing teeth and an upper contact surface capable of contacting said housing upper surface, said gripper including a recess facing said second end of said housing; and a plunger rod having a first end slidably extending through the bore in said housing second end and a second end outside of said housing, wherein said first end of said plunger rod is received by said gripper recess when said plunger rod is advanced into said midportion until contacting said gripper such that when said first end of said plunger rod is fully received by said gripper recess said gripper teeth disengage from said housing teeth which permits said connecting rod to be advanced further into said housing.
