Pipe ejector mechanism and method

摘要

An ejection mechanism, which in one embodiment selectively ejects pipe joints to either side of a pipe arm and method for manufacturing the same. A pipe arm contains a plurality of pipe receptacles for receiving pipe joints. Pipe ejection arms are operatively connected to an ejection control mechanism. In one embodiment, at least one torsional member and/or at least one hydraulic actuator allow an operator to selectively eject pipe joints to either lateral side of the pipe arm as needed during drilling and production operations.

1. A pipe ejection mechanism for ejecting pipes, comprising:
a pipe arm movable between a lowered position and a raised position; at least one receptacle on said pipe arm operable for receiving at least one pipe; a plurality of first pipe ejector arms for moving said at least one pipe from said pipe arm in a first lateral direction with respect to said pipe arm, wherein said plurality of first pipe ejector arms pivot to lift said at least one pipe and to form a slope for rolling said at least one pipe on said plurality of first pipe ejector arms; a plurality of second pipe ejector arms for moving said at least one pipe from said pipe arm in a second lateral direction different from said first lateral direction with respect to said pipe arm, wherein said plurality of second pipe ejector arms pivot to lift said at least one pipe and to form a slope for rolling said at least one pipe on said plurality of second pipe ejector arms; a first torsional rod in connection with said pipe arm on a first side of said pipe arm, wherein said plurality of first pipe ejector arms are connected to said first torsional rod, wherein said first torsional rod pivots the plurality of first pipe ejector arms; and a second torsional rod in connection with said pipe arm on a second side of said pipe arm opposite said first side, wherein said plurality of second pipe ejector arms are connected to said second torsional rod, wherein said second torsional rod pivots the plurality of second pipe ejector arms, wherein the plurality of the first pipe ejector arms comprise a first upper edge extending the distance between the receptacle and the first torsional rod, wherein the at least one pipe rolls on top of the first upper edge the distance between the receptacle and the first torsional rod, wherein the plurality of the second pipe ejector arms comprise a second upper edge extending the distance between the receptacle and the second torsional rod, and wherein the at least one pipe rolls on top of the second upper edge the distance between the receptacle and the second torsional rod.
