Abstract: A locking device includes an outer portion and an inner portion. The outer portion has a bore formed at least partially axially therethrough and a channel formed laterally therethrough. The inner portion is positioned at least partially within the bore. A first link is positioned at least partially outside of the outer portion and coupled to the inner portion through the channel. A second link is coupled to the outer portion. A pin is coupled to the first link and the second link. The locking device is in an unlocked state when the inner portion is fully positioned within the bore, and the locking device is in a locked state when an end of the inner portion extends axially out of the bore.

Abstract: A pipe-handling apparatus for moving a pipe relative to a drilling floor of a drilling rig, the pipe-handling apparatus having a main support structure; a pipe delivery mechanism for delivering pipe between a pipe load/unload position and a drilling floor position; and at least one walking unit comprising: a jack capable of lifting the main support structure in a substantially vertical direction; and a foot capable of moving the main support structure in a substantially horizontal direction.

Abstract: Systems and methods for vertical pipe handling include telescopic arm structures that move between retracted and extended positions in a horizontal plane, a cross arm structure connected to each telescopic arm structure, and a gripper head connected to the cross arm structure. The gripper head may be positioned at a desired location to receive, grip, position, and release a vertically oriented drill pipe or other tubular, and may include jaws that can be positioned to accommodate different sizes of drill pipe or tubulars. Means for raising and lower the gripper head, extending or retracting the gripper head in a horizontal plane, and tilting or pivoting the gripper head may also be provided. The vertical pipe handler may be housed below the drill floor and attached to the drill floor support structure.
