- pipe can be rolled on, free of the bulkhead, and when the carriage assembly is moved toward the left, as shown in FIG. 13 , the bulkhead moves into the position shown in FIG. 12 , and provides an abutment against which-the pipe can be bear when the carriage assembly is moved to the position for travel up the ramp and eventual off bearing of the pipe onto the drill floor.
Abstract
A method and apparatus for handling pipe and other elongate objects to transfer the material from a first station, such as from a pipe rack to an elevated station, such as the floor of a drilling rig is disclosed. The apparatus includes a subframe, an outer frame and an inner frame when the inner frame is provided with an elongate, substantially flat upper surface. A ramp is mounted at a downstream end of the subframe, and the inner frame is operable for receiving the elongate objects and the outer frame and inner frame, which may be thought of as a carriage assembly, rectilinearly shifted toward the ramp. To facilitate loading of the elongate objects from the first station, the upper surface of the inner frame may be selectively tilted to facilitate loading, and then as the carriage assembly is rectilinearly shifted downstream, toward the ramp, the upper surface is sequentially moved to a substantially flat position, whereby the carriage assembly then moves up the ramp so that the elongate objects may be off-loaded at the elevated station.

- The pipe handling apparatus of the present invention is generally designated at 10 in
FIG. 1 , and includes an upwardly extendingramp 12, having spaced-apart, elongate tracks extending along the upper surface. The ramp includes afirst section 12 a inclined upwardly, acurved transition portion 12 b and a finalhorizontal portion 12 c for mounting adjacent a drilling rig. The ramp is pivotally connected at 14 to asubframe 16, so that it can be folded up in the configuration shown inFIG. 1A for transport. A wheeled carriage assembly, generally indicated at 18, is reciprocally shiftable alongsubframe 16 and the ramp, and includes an inner frame for carrying pipe, mounted on an outer frame. The outer frame is shiftable from a home position, where pipe is received or,discharged, to an elevated position for delivering or receiving pipe from adrill floor 20 of a drilling rig generally indicated at 22 inFIG. 1 . - As shown in
FIG. 2 , which is a top plan view,ramp 12 is provided with opposed, spaced-apart,elongate tracks elongate tracks subframe 16. These tracks enable reciprocal displacement there along ofcarriage assembly 18. As shown inFIG. 1 ,carriage assembly 18 is operable for reciprocal translation alongtracks FIG. 1 to the elevated position shown inFIG. 3 , where pipe can be off-loaded onto the drill floor or taken away as the case may be. The principal components ofcarriage assembly 18 can be appreciated from a viewing ofFIGS. 5, 6 and 6A. The carriage assembly includes a wheeled outer frame, generally indicated at 32, operable for reciprocal shifting alongsubframe 16 and for carrying an inner frame, generally indicated at 34. The inner frame may be thought of as a “pan,” for holding pipe or casing to be delivered, as will be hereinafter described. - The completed assembly of
subframe 16,outer frame 32 andinner frame 34 can be appreciated from viewing the cross-sectional view taken along line 7-7 ofFIG. 2 , reproduced atFIG. 7 . As shown inFIG. 7 ,subframe 16 is provided with a pair of ground-mounted, spaced-apart I-beams tracks Subframe 16 also includes supporting structure indicated at 40 which includes a plurality of tubes, such as indicated at 42, for tying the structure together and for mounting dual-inclined cams, a front pair generally indicated at 44 and 44 a inFIGS. 4, 7 and 8. There are two pairs of these cams, two adjacent the front end ofsubframe 16 and two adjacent the rear-end as shown inFIG. 4 . A rear pair, one of which is shown at 45 inFIGS. 1 and 2 . The cam oppositecam 45 on the subframe is hidden from view, but all are substantially identical in construction. The basic cam construction is shown inFIG. 8 , withcam 44 as an example. It has a pair of inclined planar surfaces, a first “fast rise” surface indicated at 46 and a second “slow rise” surface indicated at 48. The inclination ofsurface 46 is at an angle α of approximately 100, relative to the horizontal as shown, whereassurface 48 is inclined relative to the horizontal at an angle β of approximately 2°, as also shown inFIG. 8 . The two cams mounted onbeams subframe 16 are substantially identical to the rear pair of cams, one shown at 45 to the right inFIG. 4 . - As also shown in
FIG. 4 ,subframe 16 is provided with adrive motor 50 suitably connected by a gear reduction box to adrive sprocket 52 which is operable for transmitting power to adrive chain 54, trained around arear sprocket 53. The ends of the chain are connected to a lug mounted at the rear ofouter frame 32, for selectively translating the outer frame from a first or “home” position onsubframe 16 to the elevated position shown inFIG. 3 . As can be seen inFIG. 5 , outer frame 32 (see alsoFIG. 7 ) includes a pair of elongate,tubular beams FIG. 7 and the rear pair at 64 and 66 (seeFIG. 2 ).Outer frame 32 also includescross members 66 which supportinner frame 34 when the inner frame is mounted to seat withinouter frame 32, as shown in the schematic view ofFIG. 7 . It can be seen thatinner frame 34 includes an upper surface 35 and a central section, generally a U-shaped configuration, which is indicated at 37 and is engageable for normally seating against the upper surfaces of cross members 66 (seeFIG. 5 ). Upper surface 35 may be referred to as a “pan” for carrying pipe, etc., and includes sides such as 37. As shown inFIGS. 6 and 7 ,inner frame 34 includes opposed pairs of interconnected levers with cam-engaging rollers adjacent the front and rear ends of the frame, respectively. Each of the levers is pivotally connected to the inner frame and includes a roller, for example, as shown inFIGS. 7 and 8 ,front lever 68 is pivotally connected at 70 to the inner frame and is connected by anelongate rod 82, and includes a roller, such asroller 72, androller 74 onlever 69 is provided on the other side (seeFIGS. 6A and 7 ). At the rear of the inner frame, as shown inFIG. 6 , a rear lever is shown at 76, pivotally connected at 78 toinner frame 34 and includes aroller 80. Anarm 77 a extends upwardly fromlever 76 and is part of anactuating mechanism 77, to be described later.Elongate rod 82, which interconnects levers 68 and 76, as can be seen inFIG. 6 andFIG. 12 , so that the levers move or pivot in unison in the same orientation. It should be understood that lever 68 (seeFIG. 7 ) is also interconnected by a rod to a lever directly opposite to that oflever 76. Thus, there are front pairs of levers and rear pairs of levers, the levers on a common side being interconnected by a rod, such asrod 82, actuated by anactuating mechanism 77 to preselect orientation oflevers Arm 77 a may be thought of as an actuator for preselecting positioning oflevers actuating mechanism 79 includes anarm 79 a provided with ahandle 77 b to preselect position oflever 69 and its associatedroller 74, as well as the position of the rear lever opposite to that oflever 76. - As shown in
FIG. 11 , eachactuating mechanism handle FIG. 2 to the pipe rack indicated at 86. - The pipe handling apparatus of the present invention finds particular utility in providing a method and machine which can be quickly adjusted to receive and then send pipe or casing to the drill floor. No hydraulic or motor-operated positioners are required. Initially, it will be assumed that drill pipe, in the range of 31-feet, for example, has been previously arranged in rows on elevated pipe racks, such as those indicated at 84. (Drill pipe of course, could be initially loaded on the opposite pipe racks 86).
Drill pipe 88 is to be loaded or rolled ontoinner frame 34 andtransport carriage assembly 18 so that the pipe is in position to be sent to the drill floor, such as shown inFIG. 3 . At the drill floor the pipe may be removed by a suitable draw works such as shown at 23, or the like, operated by a crew on the drill floor. There are two ways that the inner frame or “pan” may be arranged for receivingdrill pipe 88. The first is to position actuatingmechanisms FIGS. 7 and 8 . An operator (seeFIG. 11 ) removes locking positioning bolts or pins 92 fromapertures 94 inarcuate guides arm 77 a aboutpivot 78 which in turn pushesrod 82 in a forward direction to thereby pivotlever 68 aboutpivot 70 to thereby retract or pivot upwardlyroller 72, in the position shown in dashed lines inFIGS. 8 and 12 . In that position,rollers cams arm 79 a to a forward position, such as shown inFIG. 11 , which actuates rod 92 (similar to rod 82) so thatroller 74 onlever 69 androller 75 mounted onlever 71 are both retracted and will not engage the cam opposite tocam 45. - The operator then operates
motor 50 to shift the carriage assembly into the position generally shown inFIG. 1 , i.e., retracted to a “home” position, whereinner frame 34 will have its surface 35, as shown inFIG. 7 , positioned beneath the upper edges ofelongate beams outer frame 32. As shown inFIG. 7 ,pipe 88 can now be rolled frompipe rack 84 over the top surface ofbeam 58 and displaced onto surface 35 ofinner frame 34. The operator now engagesmotor 50 to rotatedrive sprocket 52 in the counterclockwise direction (viewingFIGS. 1, 2 and 4), so thatcarriage assembly 18, withpipe 88 loaded onto the upper surface ofinner frame 34, is transported alongsubframe 16 and then diagonally upwardly alongramp 12 to the position shown inFIG. 3 , wherewheels curved transition 12 b and alongportion 12 c to the final position wherein the pipe can be off-loaded by draw works 23. It will be noted that the pipe is held in position on the upper surface ofinner frame 34 by means of abulkhead 100. After the pipe has been off-loaded at the drill floor, the operator reverses the drive sprocket to rotate in the clockwise direction, to returncarriage assembly 18 to its home position, and loading of pipe, or casing can continue, and the process continuously repeated, as needed, until the required pipe and casing have been sent to the drill floor. - If it is desired to have a smoother transition of drill pipe onto the upper surface of
inner frame 34, orientation of the inner frame to the position shown inFIG. 7A may be accomplished. Assuming that the carriage assembly has been returned to its home position, and thatinner frame 34 is positioned below the tops ofbeams FIG. 7 , an operator may remove lockingpins 92, grip handle 79 b and pull rearwardly, along the direction of arrow A, to a position whereby the front and rear rollers connected to the levers in turn connected torod 92 andarm 79 a are extended approximately half-way down. As shown inFIG. 7A , that tilts the side of upper surface 35 downwardly toward the opposite pipe rack, as shown, so that a smoother rolling transition ofpipe 88 onto upper surface 35 is assured. After a predetermined amount of pipe has been loaded on upper surface 35, the operator actuates the drive system so that the carriage assembly is transported toward the ramp, and as the rollers of the extended levers roll off their associated cams, the upper surface levels out and the pipe is then advanced or sent to the drill floor until it is in the position shown inFIG. 3 where it is then off-loaded. Of course, pipe can be loaded from either of the pipe racks, or casing from either of the pipe racks onto the upper surface of the “pan” orinner frame 34. - Assuming that a drilling operation has been completed, or if for some other reason, it is desired to return pipe or casing to the pipe rack, the following sequence of operations is contemplated. Initially, it will be understood that it is desired to off-load pipe onto the carriage assembly fully driven up onto
ramp 12 as shown inFIG. 3 , and then transported downwardly along the ramp and to the home position whereby the pipe is automatically “kicked” off the upper surface ofinner frame 34 onto a preselected pipe rack. To do this, it is first determined which pipe rack is to receive the pipe, such aspipe rack 84. WhileFIG. 9 shows pipe being rolled off, it will be assumed initially that there is no pipe, andcarriage assembly 18 is in its home position. It is necessary to extend the associated cams, so thatinner frame 34 and in particular its upper surface 35 are inclined toward the pipe rack that is to receive the pipe. In this instance, shown inFIG. 9 , the pipe rack is indicated at 84 and therefore actuatingmechanisms FIG. 9 , wheninner frame 34 is in its “home” position. - With respect to lever 68, and its
roller 72, as shown inFIG. 10 ,actuating mechanism 77 has been positioned so that the left side (as seen inFIG. 9 ) ofupper surface 34 is positioned higher than the right side. As can be seen, however, both of the actuating mechanisms have been suitably positioned so that pan surface 35 is raised, albeit tilted to one side, relative to its normal position when the levers are fully retracted. In the position shown inFIG. 9 , as the operator sends an empty carriage assembly toward the ramp, as the followers roll off the front edges of their associated cams, the upper surface is lowered to the substantially horizontal position and is held in that orientation by thecross members 66 onouter frame 32. The carriage assembly is then moved to the top position shown inFIG. 3 , and workers on the drill floor load pipe onto the inner frame, so that the pipe has one end bearing againstbulkhead 100. When the inner frame has been sufficiently loaded with pipe (or casing as the case may be) the operator then actuatesdrive sprocket 52 in the clockwise direction to returncarriage assembly 18 to the right ofFIGS. 1, 2 and 3. As the carriage assembly proceeds toward the rear ofsub beam 16, the rear rollers, such as those connected to the rear levers, engage the rear cam surfaces at the same time that the front followers, such as indicated at 72 and 74, engage the forward cams. At this time, the upper surface ofinner frame 34 begins to tilt to the right, as shown inFIG. 9 , until the home position is reached whereby the maximum tilt is obtained andpipe 88 is “kicked” off and ontopipe rack 84 as shown. After the pipe is off-loaded in this manner, the operator reverses the drive so thatsprocket 52 is driven in the counterclockwise direction and the carriage assembly is moved back up to the ramp for further off-loading of pipe, or casing, etc. It will be apparent thatactuating mechanisms FIG. 9 , it will tilted to the left, if it was desired to off-load pipe ontopipe rack 86. - An important feature of the present invention resides in the operation of
bulkhead 100 as pipe is being off-loaded onto a rack, or loaded onto the carriage assembly. When pipe is to be off-loaded, as shown inFIG. 12 , the carriage assembly is moved toward the rear ofsubframe 16, as shown inFIG. 13 , and as the rear rollers, one of which is indicated at 80, lift the inner frame upwardly, that causes arm 104 to pivot downwardly, as shown inFIG. 13 , and pulllink 106 toward the right, as it pivots aboutpivot point 108, thereby pullingbulkhead 100 away from the end ofpipe 88, creating a gap shown at 110 so that the pipe may freely roll off onto the pipe rack, when the pan is elevated into the “kicking off position. Conversely, pipe can be rolled on, free of the bulkhead, and when the carriage assembly is moved toward the left, as shown inFIG. 13 , the bulkhead moves into the position shown inFIG. 12 , and provides an abutment against which-the pipe can be bear when the carriage assembly is moved to the position for travel up the ramp and eventual off bearing of the pipe onto the drill floor.
