Description
- This invention relates to an apparatus for transferring pipe between a pipe rack and a pipe handling apparatus.
- In the prior art there are various methods and devices for lifting tubulars to and from a drilling rig floor. One of such methods simply attaches a wire cable to the pipe and then the cable is lifted by a hydraulic winch which is typically mounted on a truck parked near the rig.
- Cranes have also been used to lift the pipe. Hydraulic driven chains have been successfully used too. Pipe transferred by these methods can be dropped on personnel or equipment below causing severe injury and damage inasmuch as they can weigh thousands of pounds. Often the pipe must be lifted to heights of forty feet or more. These dangers are more intense when the apparatus and rig are positioned offshore and subjected to wave, tidal and wind forces.
- If the pipe is dropped or banged against other structure the threaded ends can be easily damaged or the pipe bent.
- An apparatus is known from US Patent No." 3.810.553 which enables to transfer tubes from two magazines or racks, situated on either side of the device, towards a drilling platform.

- This necessary care of the threads and pipe ends creates an extra step in the installation fo the pipe or other tubular in the hole resulting in a longer cycle time.
- According to the present invention, the apparatus comprises :
- - an elongated main support frame adapted to be located close to the pipe rack means,
- - an elongated pivotal trough means having one end pivotally coupled to said main support frame such that said pivotal trough means can be pivoted upward to an inclined position relative to said main support frame and toward said drilling rig floor and downward to a generally horizontal position,
- - a portion of said pivotal trough means adjacent said pipe rack means comprises a dump trough means, said dump trough means being adapted to support a lenght of pipe,
- - a tilting means for tilting said dump trough means when said pivotal trough means is in a generally horizontal position, whereby pipe can move laterally between said pivotal trough means and said pipe rack means when in a tilted position and said dump trough means is generally flush with the rest of said pivotal trough means when in an utilted position,
- - a pivoting means for pivoting said pivotal trough means between said inclined position and said generally horizontal position,
- - a movable elongated structure adapted to receive and carry pipe and supported for lenghtwise sliding movement in said pivotal trough means,
- - a moving means for moving said movable elongated structure along the length of said pivotal trough means,
- - a coupling means for coupling said elongated structure to said moving means, and
- - a holding means for holding said elongated structure to said dump trough means to allow said elongated structure to tilt with said dump trough means.
- Accordingly, it is the principal object of the present invention to provide an apparatus for transferring pipe rack and a pipe handling apparatus.
- Another object of the present invention is to provide an improved tubular handling apparatus which can be used effectively and safely under varying weather conditions on offshore units with tubulars of various diameters and lengths.
- A further object of the present invention is to provide a tubular handling apparatus that has an automatic pipe feeder to attain a pipe transferring cycle time shorter than that of the drilling crew.
- A further object is to provide an improved pipe handling apparatus that can be easily moved to different locations on a drilling rig.
- A still further object is to provide a pipe handling apparatus that can transfer pipe from racks on one side of the apparatus to the other side without necessitating the use of additional equipment, e.g. a crane.
- Another object is to provide an apparatus that can handle pipe without damaging the pin ends thereof and that does not require that protective caps remain or be placed on the pipe ends.

Thelug 107 is rotatably located in an aperture l09 formed through a bearing member 111. Member 111 is rotatably mounted on an upper shaft l13 which is supported by twomounts trough 101. Theshaft 113 freely extends trough apertures 115A and 117A formed throughmounts mounts shaft 113 and theshaft 113 can rotate relative to member 111. Arotary actuator 121 is fixedly secured to the trough 191 by way of aplate 123 which is secured to theactuator 121 and to thetrough 101. Theactuator 121 has a lower shaft 125 which can be rotated in opposite directions. The lower shaft 125 is fixedly secured to alinkage 127 which is coupled to theshaft 113. Thelinkage 127 has anaperture 127A which freely receives theshaft 113 whereby the linkage can rotate about theshaft 113. When theactuator 121 rotates its shaft 125 in one direction, thelinkage 127 is rotated causing the linkage to turn about theshaft 113 and hence tilt theactuator 121 and thetrough 101. In Figure 3, thetrough 101 is shown in dottedlines tilted laterally in opposite directions. In Figure 3, theactuator 121 is not shown tilting with the trough for purposes of clarity. - The
rotary actuator 12 is a commercially available actuator hydraulically actuated. Referring to Figure 6, it comprises acylinder 129 having twopistons 131 and 133, with arack 135 connected between the pistons. Therack 133 engages a pinion 139. The shaft 125 is an extension of the pinion 139. When pressure is imposed on one side of thecylinder 129 it drives the piston and the rack in one direction to rotate the pinion 139 and hence the shaft 125. On the opposite side of the cylinder the pressure is released. In Figure 6,member 140 is the cylinder for therotary actuator 141 for thetilting mechanism 105.Actuator 141 is the same asactuator 121. Thecylinder 140 has twopistons rack 145 connected between the pistons for rotating apinion 146 from which extends a shaft similar toshaft 107. Both actuators ofmechanisms reservoir 93 and pump 95 for driving their shafts in the same direction for tilting thetrough 101. Fourway valve 143 is employed for controlling the direction in which the twoactuators trough 121 is tilted. - The
arms trough 101 operate in the following manner to transfer pipe between therack 27 and thepipe handling apparatus 21. Assume that pipe is to be transferred fromapparatus 21 upward to therack 27. Thearms trough 101 will be just below thecatwalk 69 in a non-tilted position whereby the V of thetrough 101 will be straight up. In this position, the upper edge of thetrough 101 is located close to thecatwalk 69 with very little space between the trough edge and thecatwalk 69 such that pipe rolling outward on thecatwalk 69 will roll into thetrough 101. Theintermediate position 39A of thefloor 39 of thetrough 31 is tilted laterally to dump a length of pipe onto thecatwalk 69. From the catwalk, the pipe will roll into thetrough 101. Thearms trough 101 reaches the top of therack 27, upward movement of thearms trough 101 will be tilted laterally in a direction to dump the length of pipe onto the top of therack 27. Thetrough 101 will be moved to a non-tilted position and thearms trough 101 moved downward to repeat the process. - For transferring pipe from the
rack 27 to thepipe handling apparatus 21, thearms trough 101 operate in the following manner. Assume that pipe is to be transferred from an upper row of pipe on therack 27 to thepipe handling apparatus 21. Thearms trough 101 will be just below the top row of the pipe on therack 27 with thetrough 101 in a non-tilted position whereby the V of thetrough 101 will be straight up. A length of pipe will be pushed into thetrough 101. Thearms trough 101 carrying the length of pipe downward in a horizontal position. When thetrough 101 reaches the level of thecatwalk 69, downward movement of thearms trough 101 will be tilted laterally in a direction to dump the length of pipe into thecatwalk 69 where it will roll into thetrough 31. Thetrough 101 will be moved to a non-tilted position and the"arms trough 101 moved upward to repeat the process. - A pair of
arms tiltable trough 101 as described above will be located on both sides of theapparatus 21 for transferring pipe between eitherrack 27 and theapparatus 21. - When the incline of the
troughs slidable apron 151 removably attachable to thepipe moving device 49 of thepipe handling apparatus 21 for carrying pipe from thederrick floor 25 down thetroughs derrick floor 25 and theframe 29 of thepipe handling apparatus 21. Theapron 151 comprises a V-shaped member slidable on thefloor 39 of thetrough 31. Anaperture 153 is formed close to the rear end 151A of theapron 151 into which is fitted a triangular shaped securingmember 155 which projects upward from a forward extension of theneck 56 ofmember 49. Theaperture 153 does not extend all of the way to the rear end 151A of theapron 151 but is spaced therefrom a short distance. Themember 153 slants downward toward its forward end whereby themember 155 may be inserted into theaperture 153 by moving themember 49 forward while theapron 151 will ride upward on themember 155 as it moves forward until it reaches full length of theaperture 153 at which time the apron will drop down the themember 155 located in theaperture 153. When themember 49 is moved forward by the chain, itsfront end 49A will engage the rear end 151A of the apron and push theapron 151 forward along thetrough 31. For drawing pipe from the derrick floor, theapron 151 will be pushed onto the fixedtrough 33. A length of pipe will be loaded onto theapron 151 and themember 49 will be moved backward by thechain 51 pulling theapron 151 and hence the pipe backward whereby the pipe may be loaded onto therack 27. When themember 49 moves backward therear end 155A of themember 155 engages the rear end 153B of theaperture 153, pulling theapron 151 backward. As seen in Figures 7, 11, and 12, the intermediate or dumpportion 39A of thefloor 39 of thetrough 31 has two elongatedapron holding strips apron 151 is pulled onto theintermediate portion 39A, theouter edges 151B and 151C of the apron slide under thestrips portion 39A. Thus when thetrough 31 is lowered to a horizontal position and thedump portion 39A is pivoted laterally, theapron 151 also will be tilted laterally allowing the pipe to be dumped onto thecatwalk 69 for loading onto arack 27 next to theapparatus 21. During dumping operations by thedump portion 39A,member 49 will not be located above thedump portion 39A. When theapron 151 is tilted laterally by thedump portion 39A, itsaperture 153 is moved above themember 155. However, when the apron is moved back in place by thedump portion 39A, theaperture 153 will fit around themember 155 whereby themovable member 49 may push the apron along thetrough 31 to the fixedtrough 33. - Although the
apron 151 is used primarily for drawing pipe from the derrick floor for loading on the rack, it is to be understood that it would be used for moving pipe from therack 27 to the derrick floor. Theapron 151 also has advantages in that it protects themain troughs apron 151 to minimize friction. - When the height differential between the
derrick floor 25 and theframe 29 is sufficient such that the pipe will slide downtroughs apron 151 may be removed as well as the securingmember 155.Member 155 may be removably secured to the forward extension of theneck 56 ofmember 49 by bolts. - Instead of employing the
strips apron 151 to thedump portion 39A, theapron 151 may have a thin neck extending down from its bottom with an enlarged lug attached to the thin neck. The thin neck will extend trough theslot 53 with the enlarged lug located below thefloor 39. This arrangement allows theapron 151 to slide on thefloor 39 yet holds theapron 151 to the dump portion when it is tilted for dumping purposes. In this embodiment, theapron 151 may be coupled to themember 49 by securingmember 155 to the forward extension of theneck 56 ofmember 49 through theaperture 153 of theapron 151 when theaperture 153 of theapron 151 is over the forward extension of the neck. Theapron 151 may be removed by removingmember 155 and by sliding the apron forward when thetrough 31 is at a slightly inclined position to remove the lower thin neck of the apron from theslot 53 at the forward end of thetrough 31. - Preferably the
apron 151 will be longer than the length of pipe it will carry.
