PIPE HANDLING SYSTEM FOR PRESENTING SECTIONS OF PIPE TO A DERRICK WORK FLOOR HAVING A PIPE EJECTION ASSEMBLY

摘要

A pipe handling apparatus for raising and lowering pipe to and from a raised derrick work floor. The apparatus comprises a longitudinally-extending base, with a longitudinal ly- extending cavity therein. An elongate, longitudinally-extending boom member is provided, whic h is adapted for raising out of and nestable positioning in such cavity. The boom member has a longitudinally-extending trough therein on an upperside surface thereof, adapted to receive at least one section of pipe. At least one arm member is coupled to the boom member for raising a proximal end of such boom member. A pipe ejection assembly, integrated into said boom , is operable as the boom lowers into the cavity for the purpose of laterally ejecting pipe from the trough. The ejection assembly is adaptable for uni-directional or bi-directional ejectio n. Motive means are provided to permit powered movement of the ejector members when the boom is nested.
