Description
"PIPE HANDLING APPARATUS"
FIELD OF THE INVENTION
The present invention relates generally to pipe handling systems and in particular to a system for providing pipe to, and receiving pipe from, work floors of a derrick or rig which may be positioned at various heights from the ground.
BACKGROUND OF THE INVENTION
Drill strings of pipe for oil and gas wells are assembled or disassembled vertically on a derrick one joint at a time, and are stored horizontally on pipe racks situated on the ground adjacent the rig. The work floor of the rig is typically elevated substantially above the pipe rack such that transferring sections of pipe to and from the work floor and the racks is necessary and requires careful handling of the heavy pipe to protect the workers and the pipe.
As shown in Figure 1, a common prior art solution in the context of a transportable trailer is a pipe handling apparatus implementing a base supporting a pivoting boom having a pipe receiving trough along its upper surface. The boom has an upper end which can be placed adjacent to and raised to the height H of a derrick or rig floor (not shown), and a lower end which is movable along the base.
Typically the lower end is guided in a cavity in the base which also serves to receive the boom therein when lowered. An arm pivots between the base and the boom for raising the boom from the base to the floor height. At the end of a pipe lowering operation, as well as during transport or storage, the boom is retracted to nest into the cavity.
Although effective to raise the upper end to a predetermined height H, this type of prior art pipe handling apparatus does not readily permit adaptation to raise the upper end to a range of different rig floor heights. Additionally, this type of prior art pipe handling apparatus also does not readily permit a variety of horizontal placements of the upper end of the boom, such as closer to, or further back from, a work floor of the rig.
There is a demonstrated needed for a pipe handling system wherein the boom can be raised to meet with a range of derrick or rig floor heights, as well as a range of horizontal positions relative to such derrick or rig floor, without the disadvantages of the prior art.
