AUTOMATIC PIPE RACKING APPARATUS
Apparatus for moving vertical lengths of pipe between the well bore center line and a racking assembly (20). An arm (72) having a gripping head (78, 80) mounted thereon is extendable and retractable relative to a carriage (82) mounted on the drilling rig working board. When storing pipe, the lower e...

| description | Apparatus for moving vertical lengths of pipe between the well bore center line and a racking assembly (20). An arm (72) having a gripping head (78, 80) mounted thereon is extendable and retractable relative to a carriage (82) mounted on the drilling rig working board. When storing pipe, the lower end of each pipe is set on a support assembly (37, 39) which includes a plurality of switches (182, 186) which signal the position of each pipe thereon. The arm and carriage are moved under control of a computer (232) to an appropriate slot for storing the upper end of the pipe stand. When running pipe into the well bore, the arm and carriage move the upper end of the pipe to the center line of the well and when the travelling block of the drilling rig picks up the pipe, a signal generated by the switch beneath the pipe causes the carriage and arm to move to the location for unracking the next stand of pipe. |
