Pipe handling apparatus to move tubulars from a horizontal position on a piperack adjacent a well bore to a vertical position over the wall center or mousehole. A bicep arm assembly is pivotally connected to a base plate. A forearm assembly is pivotally attached to the distant end of the bicep arm assembly and a gripper head is pivotally connected to the distant end of the forearm assembly. The bicep arm assembly is mounted to the structure of the drill rig.

This application is a continuation of application Ser. No. 08/396,204 filed Feb. 28, 1995, now abandoned, which was a continuation of application Ser. No. 07/932,683 filed Aug. 20, 1992 which issued to U.S. Pat. No. 5,458,454 (Oct. 17, 1995).
A flexible container forming and filling apparatus comprising a flexible container forming assembly, a flexible container filling assembly and a transfer assembly. The flexible container forming assembly is configured for forming at least two side by side flexible containers which define at least a first output and a second output. The flexible container filling assembly is associated with the flexible container forming assembly and has a receiving region configured for receipt of sequential flexible containers for filling. The transfer assembly is configured for sequentially transferring flexible containers from the first output to the receiving region of the flexible container filling assembly and from the second output to the receiving region of the flexible container filling assembly.
An operational system and method and improved apparatus for positioning and stabbing well tubulars wherein: the grasping members of the apparatus can be folded and unfolded; the boom assembly can be pivoted to a downward clearance position; a plurality of stabbing apparatuses can be placed and used in a stacked position in the derrick; the grasping members can opened at an angle with respect the boom; the grasping members can be mounted on either lateral side of the boom; a sensor monitors the relative position of the rig top drive with respect to the stabbing apparatus; the grasping members and/or the boom will automatically pivot to a breakaway position if impacted; and/or the system is programmed and configured to prevent the accidental performance of critical operations out of sequence.
An automatic loader (10) for drill rods (11) adapted to be associated with a boring machine having a guide and drive assembly (12) for the drill rods (11) includes at least a store (13) containing a plurality of drill rods (11) and a movement assembly (14) that is able to selectively remove, one at a time, the drill rods (11) from the store (13) to position them on the guide and drive assembly (12). The movement assembly (14) is arranged in an intermediate position between the store (13) and the guide and drive assembly (12), so as to not interfere with the latter during the removal of the drill rods (11) from the store (13).
An apparatus and method for handling pipe sections, preferably for use with a drilling head. The apparatus includes a storage bin defining a substantially fixed bin dispensing position, a transfer device for individually transferring a pipe section between the bin dispensing position and a pipe transfer position, and a handling device for individually moving the pipe section between the pipe transfer position and a drilling head interface position. The method includes presenting a pipe section to the bin dispensing position, moving the transfer device to the bin dispensing position to engage the pipe section at the bin dispensing position, transferring the pipe section with the transfer device from the bin dispensing position to the pipe transfer position, engaging the pipe section with the handling device at the pipe transfer position, and moving the pipe section with the handling device from the pipe transfer position to the drilling head interface position.
A method and apparatus for transferring tubular stands between a substantially horizontal position on the catwalk and a substantially vertical position at the rig floor entry. In one embodiment of the invention, this is accomplished by moving bundles of individual tubulars to the process area, where a stand make-up/break-out machine, also called a bucking machine, makes up the tubular stands. The bucking machine aligns and stabs the connections and makes up the connection to the correct torque. The tubular stand is then transferred from the bucking machine to a stand storage area or to a trolley pick-up area. When additional stands are needed by the drilling operation, a trolley is moved into position over the trolley pick-up area to retrieve the stands previously placed in the trolley pick-up area. The stands are clamped to the trolley and the trolley is moved from a substantially horizontal position to a substantially vertical position at the rig floor entry. A vertical pipe-racking machine transfers the stands to the traveling equipment. The traveling equipment makes up the stand connection and the stand is run into the hole. The operation can also be reversed to remove stands from the rig floor entry and break out the stands in a horizontal position.
