Referring now toFIG. 19 , ascylinder 48 is moved to a retracted position,linkage 80 moves downward and causes swingarms 74 to rotate outward abouthinge members 76 and allowpipe 82 to pass between the swing arms.Cylinder 48 is then moved back toward the extended position, which causesswing arms 74 to rotate inward and engagedpipe 82, as shown inFIG. 20 . - Referring back to
FIG. 1 ,drill floor equipment 20, comprisingiron roughneck system 48 and slips 50, is used to make and break pipe connections as pipe joints are added to, or removed from, the drill string The operation ofdrill floor equipment 20 is further shown inFIGS. 21 and 22 Iron roughneck system 48 comprisestorque wrench 84 andspinner 86 mounted to swingingframe 88 and stabbing guide 90 mounted tomast 22. Swingingframe 88 forms a parallelogram-shaped support structure that allows rough-neck system 48 to be moved to and from well center as needed In certain embodiments,iron roughneck system 48 may be removed from swingingframe 88 and replaced with casing tongs or other equipment for handling specific tubular members. Alternatively, swingingframe 88 may allow foriron roughneck system 48 to be rotated to an elevated or other position that allows for the use of casing tongs or other equipment for handling specialized tubular members. - As pipe joint 92 is lowered, stabbing
guide 90 aligns the pipe joint withdrill string 94, which is supported byslips 50. As pipe joint 92 engagesdrill string 94, swingingframe 88 movestorque wrench 84 andspinner 86 toward the well center, as shown inFIG. 22 .Spinner 86 engages pipe joint 92 and rotates the pipe so as to engage the threaded connection todrill string 94Torque wrench 84 then applies the necessary torque to the threaded connection to secure the connection. When removing pipe joints from the drillstring torque wrench 84 applies torque to break the connection andspinner 86 rotates the pipe joint to disengage the treaded connection - As described above,
drilling system 10 andpipe erecting system 16 operates by taking pipe from a horizontal orientation and placing the pipe back in the horizontal orientation after use. Once horizontal, the pipe can be handled by a number of different pipe handling systems and methods. In certain embodiments, automated systems can be used to handle horizontal pipe without direct involvement of personnel. One such pipe handling system is illustrated in FIGS. 23A-F and 24A-F. - Referring now to
FIG. 23A ,pipe handling system 100 comprisesrack 102,frame 104,tilting mechanism 106,elevated stop 108, andpipe unloading assembly 110. Unloadingassembly 110 comprises liftingblock 114 androtating arm 116. When loadingpipes 112 ontoerector 40,tilting mechanism 106 raises the end ofrack 102 so as to angle the rack towarderector 40. The movement ofpipes 112 alongrack 102 is limited byelevated stop 108. - Referring now to
FIGS. 23B-23F , to load a single joint ofpipe 112 ontoerector 40, liftingblock 114 is raised, pushing a single joint ofpipe 112 upward Thepipe 112 moves over and pastelevated stop 108 toward the end ofrack 102. Liftingblock 114 is then lowered so that the remainder ofpipes 118 can move downward until contactingelevated stop 108. At the end ofrack 102,pipe 112 is stopped byarm 116, which is disposed in a raised position.Ann 116 is then rotated tolower pipe 112 ontoerector 40.Arm 116 continues rotating downward so that is out of the way oferector 40.Erector 40 can then liftpipe 112 upward and away frompipe handling system 100. - FIGS. 24A-F illustrate
pipe handling system 100 being used to store pipes being removed from a drill string. When movingpipes 112 fromerector 40,tilting mechanism 106 lowers the end ofrack 102 so as to angle the rack away fromerector 40. Liftingblock 114 andelevated stop 108 are retracted intorack 102 so as to provide a smooth surface along whichpipe 112 can roll. Oncepipe 112 is lowered and released byerector 40,arm 116 rotates upward so as to lift the pipe from the erector.Arm 116 continues to rotate untilpipe 112 falls ontorack 102 where it will roll toward the far end of the rack. - Another pipe handling system is shown in FIGS. 25A-H and 26A-H.
Pipe handling system 200 comprisesframe 202 that is pivotally mounted onbase 204. The incline offrame 202 is controlled bypiston 206.

system 200 is illustrated in FIGS. 25A-H. Piston 206 inclinesframe 202 so that pipe joints 212 tend to move towardpipe moving assembly 210.Finger 214 extends to separate a single joint of pipe from the row of pipes stored inframe 202.Assembly 210 the moves upward untilpipe 212 clearsframe 202, as shown inFIG. 25B .Pipe 212 will roll downassembly 210 until itcontacts arm 216, which is in an levated position. Withpipe 212 resting againstarm 216,assembly 210 moves downward alongflame 202 to the position shown inFIG. 25D .Arm 216 then rotates so as tolower pipe 212 intoerector 40 and continues rotating until reaching a lowered position as shown inFIG. 25E . Witharm 216 in a lowered position,erector 40 can capturepipe 212 and move the pipe to the drill floor. Onceerector 40 has moved out of the way,assembly 210 is moved back to uppermost row of pipes andarm 216 is rotated back to the elevated position - The loading of pipe from
erector 40 back intohandling system 200 is illustrated in FIGS. 26A-H. Piston 206 inclinesframe 202 so that pipe joints 212 tend to move away from moving assembly210 A Mover assembly 210 is disposed adjacent toerector 40, onceerector 40 lowerspipe 212 to a horizontal position. Onceerector 40disengages pipe 212,arm 216 rotates to liftpipe 212 fromerector 40.Mover assembly 210 then moves upframe 202 untilpipe 212 clears the top of the frame. Once insideframe 202,pipe 212 is restrained byextended finger 214 and bumper 215.Mover assembly 210 moves back downframe 202 untilpipe 212 is at the row of pipe being loadedFinger 214 then retracts andpipe 212 will roll into position withinframe 202.Mover assembly 210 is then moved back to the proper elevation to receive pipe fromerector 40 andarm 216 is rotated back to its lowered position. - Referring now to
FIGS. 27 and 28 , an alternatepipe erecting system 300 compriseserector system 302 that moves a single joint of pipe at a time from a horizontal position to a vertical position where the pipe is restrained byvertical support system 304.Erector system 302 further compriseserector frame 306, capturearms 308,pivot 310, elevatingcylinder 312,base frame 314,support finger 316, andfinger cylinder 318Vertical support system 304 comprisesframe 320,pipe rest 322,lower funnel guide 324, andupper funnel guide 326. - Referring to
