Definitions

  • the stand When the stand has been withdrawn by the primary elevator, it is grasped by the spider and the tong for unthreading.
  • the regular elevator then starts its downward movement from the upper position and the transfer elevator is placed around the pipe while it is being unthreaded and while theregular elevator is moving to the stand still in the borehole.
  • the transfer elevator picks up the stand and transfers it to the racking means.
  • the sequence of operations in running pipe into the hole is generally reversed; the stand being picked up by the transfer elevator and aligned with the regular elevator, then lowered through the regular elevator onto the top of the pipe already in the borehole so that the tong (which may be over the pipe in the borehole or may be placed on the transferred pipe from the side) may start the threading operation attaching the two ends together while the regular elevator moves up the transferred pipe towards the end.
  • the transfer elevator is then removed from the upper portion of the transferred stand and the latter is picked up by the regular elevator for lowering into the hole. It is essential, therefore, to have a transfer elevator which is easy to operate by the derrick man, preferably by manipulation of one hand only.
  • the invention is generally in the field of elevators for transferring segments or stands of pipe for wells, such as oil wells and the like, and is intended primarily for use with oil well pipe.
  • the applicants primarily disclose a transfer elevator for either collar or upset pipe with an improved latch for closing the elevator body opening or gate, and a releasable ice.
  • Another object is to provide an elevator of the class described which has an opening therein sufiiciently large to accommodate the largest size pipe to be worked therewith, but which has a replaceable support plate with pipe opening of suitable size to work the desired size of pipe, the elevator being adjusted to diiferent size pipe by substituting support plates with different size openings.
  • -It is another object of the present invention to provide a latch lock which locks the latch in its closed position, but which may be readily released by a hand-grip actuated by the operator.
  • FIG. 1 is a side elevational view of the transfer elevator forming the subject matter of the present invention
  • FIG. 2 is a front elevational view of the device of FIG. 1, showing the pipe-receiving opening with the latch in closed position;
  • FIG. 3 is a top plan view taken on line 3-3 of FIG. 1, looking in the direction of the arrows and indicating, in broken lines, a pipe latched in position in said elevator;
  • FIG. 4 is a view taken on the line 44 of FIG. 1, looking in the direction of the arrows, portions of the view being in cross-section and the latch being locked in closed position;
  • FIG. 5 is a fragmentary, partially cross-sectioned, view showing the latch lock mechanism of FIG. 4 in released position, with the latch mechanism still in its closed position but conditioned for movement to open the elevator;
  • FIG. 6 is a view generally similar to FIG. 4, but showing the latch withdrawn from its pipe-holding position, the view being partly fragmentary and located nearer the base or bottom of the elevator body than FIG. 4, to indicate the sidewall slot through which the latch moves into and out of pipe-retaining and releasing positions.
  • This view is partially in cross-section;
  • FIG. 7 is a vertical cross-sectional view, taken on the line 7-7 of FIG. 4, looking in the direction of the arrows;
  • FIG. 8 is a front elevational cross-sectional view, taken on the line 8-8 of FIG. 7, looking in the direction of the arrows;
  • FIG. 9 is a fragmentary elevational view taken on the line 9-9 of FIG. 8, looking in the direction of the arrows;
  • FIG. 10 is a view similar to FIG. 3, but showing a support plate adapted to use with a smaller size pipe than that indicated in FIG. 3.
  • FIGS. 1, 2 and 3 there is here shown a transfer elevator 11, having a support pipe or hanger 12 which is provided with a bail 13 to which a line or hook (not shown) may be attached to support the assembly.
  • This hanger 12 preferably is angled toward the forward portion of the elevator so that the support will be approximately over the center line of the elevator opening (hereinafter described), whereby the elevator will remain properly aligned and in balance regardless of the load being handled by the elevator.
  • an elevator body 14 Attached by any convenient means, such as welding or the like, to the hanger 12 is an elevator body 14, one side (herein sometimes referred to as the front) of which is open or U-shaped to accommodate a pipe or the like to be transferred.
  • a front view of this opening is seen at 15 and reference may be had to FIG. 4, for example, for a disclosure of a preferred shape of the opening when viewed from above the elevator.
  • the body 14 is provided with spaced outwardly extending side-wall portions 16 and 17, defining the sides of the opening 15 therebetween; and the back 18 of the opening 15 is preferably rounded to accommodate the circumference of a pipe therein. It may be noted for purposes of description, that the opening 15 formed by the side-walls 16, 17 and back 18, may be generally described as of a horizontal U-shape, although it is conceivable that it could have an angular conformation such as, partly hexagonal.
  • the opening 15 is shown as containing a pipe 19 having a collar 21, which pipe and collar are shown in broken lines for illustrative purposes only.
  • the body 14 at its rear has a rearwardly extending upper body flange 23 and a rearwardly extending lower body flange 24, with space therebetween to house the latch and latch lock mechanisms to be hereinafter described.
  • a hearing plate or support plate 25 which is of generally horizontal U-shape having an opening on one side to accommodate a pipe, is attached to the top of the elevator body by any convenient means, such as screws 26, and extends inwardly from the side-walls 16, 17 and back 18 over the opening 15 at least a short distance to partially close the vertical passage through the opening 15.
  • the U-shaped opening of the support plate corresponds generally to the configuration of the opening 15, but the support plate opening is of a size and shape to allow a pipe to be inserted therein with the pipe collar resting on the sides of the opening, or if an upset pipe not having a collar is being worked, to receive and hold the upset in said opening.
  • the opening in the support plate may be tapered to prevent damage to the pipe.
  • the support plate has a downwardly depending flange 27 adapted to seat in the recesses 28, thus increasing the strength of the support plate and giving added protection to the side-walls and back of the body 14.
  • Pipe having a tapered joint is a commonly used pipe in the oil industry as is collared pipe, and with the arrangement just above described the universal application of the elevator herein disclosed is enhanced.
  • support plates adapted to work different sizes of pipe may be readily substituted. It is noted in FIG. 10 that support plate 29 has a much smaller pipe-receiving opening than that illustrated in the device of FIG. 3.
  • the support plate 29 may be substituted for the support plate 25 for smaller pipe, and pipe of other sizes may similarly have other support plates substituted therefor, the principal limitation being the size of the opening 15 of the body.
  • the open front side of the support plates 25 and 29, respectively are preferably provided with guide surfaces slanting inwardly toward the pipe-receiving bearing surfaces to enable the operator to insert the elevator on a pipe rapidly and without delay for aligning the elevator and pipe.
  • the outer ends of the side-walls 16 and 17 may likewise be tapered to lead into the opening.
  • the upper body flange 23 and lower body flange 24 are drilled, as is evident from FIG. 7, to receive the latch pin 33 which forms a journal for a latch 34.
  • the latch 34 is preferably hook-shaped and is mounted, as best evident from FIG. 7, to swing about the latch pin 33.
  • the side-wall 17 of the body 14 is slotted, as indicated best in FIGS. 1 and 6, providing the slot 35 through which the outer end of the hook-shaped latch 34 enters the opening 15.
  • the latch 34 is free to move into the opening, as shown in FIG. 4, (see also FIG.
  • this latch extends only far enough across the opening to securely retain the pipe positioned, but terminates short of the side-wall 16. The reason for this is that when the latch is withdrawn from the opening, as shown in FIG. 6, the movement of the latch a sufficient distance to clear the opening is not excessive.
  • the latch is provided with an upstanding integral rear flange portion 36 which in turn has a forwardly extending upper flange 37.
  • the latch pin 33 extends through the flange 37 and the base portion of the latch 34 to form the mounting means for the latch 34; the flange 37 being spaced from the base of the latch 34, as is evident from FIG. 7.
  • the rear flange 36 is provided with spaced lower and upper rearwardly extending cars 39 and 41 which extend generally rearwardly at, for example, an angle of 37 to the centerline of the elevator, past the rear of the body flanges 23 and 24.
  • the ears 39 and 41 are drilled or otherwise perforated to receive a latch lock pin 42 which extends vertically therethrough and is held in place by a spiral pin 43.
  • Journaled on the pin 42 is a latch lock assembly comprising a generally crescent-shaped latch lock 44 which has formed, preferably integral therewith, a hand-grip 45, as will be apparent from FIG. 7, for example.
  • the latch lock 44 may be swung in a rotary motion about the pin 42 by manipulation of the handle 45.
  • a latch lock spring 46 or other convenient means for biasing the latch lock in a direction counter-clockwise as viewed from the top, is here disclosed as a spiral spring, one end of which (see FIG. 6) rests against rear latch flange por tion 36, and the other end of which bears against a depending, slightly oflset integral web portion between the inner ends of the handle 45 and the latch lock 44.
  • the latch lock may be described as generally crescent-shaped, having a hook portion 48 on its righthand end, as viewed for example in FIGS. 4 and 6, adapted to latch around a drive pin 49 (see FIGS. 8 and 9 in particular), which drive pin 49 is mounted in and extends below the upper body flange 23 of the elevator.
  • the latch lock has a shoulder or stop 51, herein termed first stop 51, which seats against a shoulder 52 on the flange 37 of the latch 34 and positions the latch lock when in its closed position with a locking action.
  • the latch lock 44 has a second stop 53 which, when the latch lock is rotated counter-clockwise, for example, 20 by movement of the handle 45 clockwise toward closing relation with the handle 22, engages the flange 37.
  • This engagement takes place before the handle 45 has been moved toward the handle 22 more than just enough to clear the latch lock hook 48 from the pin 49, and is the position illustrated in FIG. 5.
  • the movement from the closed position to the position of engagement of the stop 53 with the flange 37, as shown in FIG. 5, thus releasing the pin, requires only suflicient gripping effort by the operator to overcome the relatively light pressure of the latch lock spring 46. Further movement of the handle 45 toward the handle 22 to the position shown in FIG.
  • latch pin 33 is held in position in the elevator by any convenient means such, for example, as the spiral pin 54 (see FIGS. 7 and 8).
  • the elevator 11 is usually suspended by the hanger 12 in position to be placed on a pipe to be transferred or otherwise worked.
  • the operator usually grasps the hand-grip 22 and handle 45 in one hand and squeezes them together. This will rotate the handle 45 clockwise about the latch lock pin 42 toward the handgrip 22.
  • the primary movement of the handle 45 will be against the resistance of the relatively weak latch lock spring 46, requiring very little gripping pressure and placing no strain on the hand of the operator, will disengage the hook portion 48 of the latch lock 44 from the drive pin 49, and will rotate the latch lock 44 (which is integral with the handle 45) about the latch lock pin 42 mounted on the ears 39 and 41 of the latch, causing the stop 53 to move against the latch flange 37 locking up the latch lock 44, handle 45 and latch 34, and preventing further movement or rotation of the latch lock 44 and handle 45 about the latch lock pin 42.
  • This movement in the example shown, is about 20.
  • the operator to grasp the pipe, then places the elevator around a pipe, beneath the collar or upset, and releases the handle 45.
  • the latch 34 under the influence of the heavy latch spring 38, will then pivot about the latch pin 33 and the hook portion will move back through the slot 35 and across the opening 15, thus closing the opening and blocking lateral movement of pipe through the opening.
  • the latch lock 44 under the influence of the latch lock spring 46 will pivot about the latch lock pin 42 and cause the hook portion 48 of the latch lock to seat around the drive pin 49, holding the latch (by holding the ears 39 and 41 thereof) against pivoting about the latch pin 33. This effectively locks the latch and holds the pipe, the collar or upset of which is seated on the support plate 25 (or other support plate such as 29, as the case may be).
