Claims
- 1. A release assembly for operating a remote mechanism, wherein the release assembly comprises:
- a funnel-shaped body adapted to engage said remote mechanism;
- a release arm adapted to be movably mounted on said body;
- said release arm having a first end and a second end;
- said release arm connected at said first end to means for moving said release arm relative to said body;
- said second end of said release arm having means for engaging said remote mechanism;
- said means for moving said release arm being moveable to transmit forces through said release arm to actuate said remote mechanism;
- said release arm comprises means for pivotally receiving a pin at said first end, whereby said release arm is pivotally connected to said means for moving said release arm, and a central, longitudinal axis extending between said first end and said second end;
- said means for engaging said remote mechanism comprise a hook-shaped portion at said second end having a lifting surface forming a plane perpendicular to said longitudinal axis and facing said first end;
- said means for moving said release arm comprise a piston-cylinder assembly including a piston having a piston rod extending therefrom, and a cylinder housing said piston, whereby upon the introduction of a pressurized medium within said cylinder, said piston and said rod reciprocate causing said release arm to move relative to said cylinder; and
- said hook-shaped portion further comprises a tip end surface adjacent to said lifting surface and facing opposite said lifting surface, said tip end surface having a planar portion extending angularly in relation to said plane formed by said lifting surface;
- said means for moving said release arm further comprise an extended section extending from said first end of said release arm in a direction perpendicular to said longitudinal axis;
- said extended section comprises a pin contact surface forming a plane perpendicular to said longitudinal axis and facing said second end;
- said pin contact surface is adapted to engage a pin member fixed relative to said cylinder when said piston rod extends from said cylinder, thereby causing partial rotation of said release arm;
- said means for moving said release arm further comprise a pair of side plates each, respectively, extending from said cylinder on opposite sides of said release arm; and
- said pin member is affixed in between said side plates.
BACKGROUND OF THE INVENTION
This is a continuation of abandoned U.S. patent application Ser. No. 08/312,177 filed on Sep. 26, 1994, which is a continuation of abandoned U.S. patent application Ser. No. 08/002,008 filed on Jan. 8, 1993. This invention rotates to a mechanical system used to establish a structural connection between a remote tool and remote mechanisms. More specifically, the invention provides means for establishing a connection between a remote tool and a subsea well structure so that mechanisms on the well structure can be maintained or operated.
