Definitions

  • the front legs extend down 'wardly from the top of the derrick in parallel relation for at least the major portion of the distance from top to bottom of the derrick and form the rails of a guide track.
  • a travelling block dolly Mounted on this track is a travelling block dolly that is movable up and down the track.
  • the front of the derrick between the track rails is open to allow stands of pipe to be moved through the track into and out of the derrick.
  • FIG. 1 is a side view of the derrick
  • FIG. 2 is a front view
  • FIG. 3 is a fragmentary rear view
  • FIG. 4 is an enlarged horizontal section taken on the line IV-IV of FIG. 2;
  • FIG. 5 is a fragmentary horizontal section of a modification.
  • a structural steel derrick which may be assembled piece-by-piece from the ground up or may be pre-fabricated and swung up to erect position from a reclining position on the ground, has two back legs 1 that diverge downwardly from the rectangular top or crown 2 of the derrick. Preferably, these legs are straight and inclined from top to bottom. Their widely spaced lower ends give stability to the derrick. These legs are rigidly connected by cross braces in the form of girts 3 and diagonal bracing members 4, as shown in FIG. 3.
  • the front legs 6 of the derrick are shown disposed in a vertical plane and extend downwardly from the top of the derrick in parallel relation as illustrated in FIG. 2. Although these legs may extend straight down to the base of the derrick, for clearance on the working floor it is preferred that their lower ends terminate some distance above the base.
  • the lower portion of the legs then are formed from downwardly diverging leg members 7 secured to the parallel portions of the legs and sloped forward to increase the distance between the front and back feet of the derrick.
  • the front legs therefore extend downwardly from the top of the derrick in parallel relation for the major portion of the distance from top to bottom of the derrick and then slope out away from the body of the derrick as shown in FIGS. 1 and 2 to give the derrick stability and a large working area.
  • the portions of the parallel legs 6 below the points at which the leg members 7 are attached do not serve as legs, but as extensions of the vertical members.
  • the parallel legs are rigidly connected to the back legs 1 by cross members formed of girts 8 and diagonal braces 9. As shown in FIG. 2, there are no cross members connecting the front legs, except possibly near their upper ends, but the usual racking platform 11 projects forward from the front legs for receiving stands of pipe moved out of the derrick through the open front side.
  • a crown block 12 mounted on top of the derrick supports the usual lines 13 that suspend a travelling block 14 inside the derrick and connect it with drawworks 15 (FIG. 3 behind the derrick.
  • the front of the derrick is considerably narrower for most of its height than the back of the derrick, as indicated in FIG. 4.
  • the diverging lower portions 7 of the front legs give the derrick stability.
  • the travelling block is prevented from twisting in the derrick, or swinging and swaying due to the wind or to the rolling of a barge on which the derrick may be mounted. Accordingly, the travelling block is attached to a dolly 17 that runs up and down a guide track inside the derrick. Unlike presently known tracks for this purpose, this derrick does not contain a separate track spaced from the derrick legs, but utilizes the parallel portions 6 of the front legs themselves as the rails of the track. As shown in FIG. 4, these rails may be formed from I- beams provided with an extra intermediate pair of flanges 18. The dolly is provided with four pairs of wheels 19 which are disposed between these extra flangesand the innermost flanges of the beams. The wheels are mounted in brackets 20 secured to the frame of the dolly.
  • the webs of the rails 6 shown in FIG. 4 are parallel to each other, which is the preferred arrangement when the derrick is to be used on land with a powered swivel.
  • the rails 22 are positioned with their webs in vertical planes converging toward the center of the derrick, as shown in FIG. 5, to better restrain the travelling block from motion due to ship roll.
  • the dolly may take the form of the one shown in U.S. Pat. No. 3,281,122 if desired.
  • An oil well derrick having a front and a back, comprising two front legs and two downwardly diverging back legs, rear cross braces rigidly connecting the back legs, side cross braces rigidly connecting the front legs to the back legs, the front legs extending downwardly from the top of the derrick in parallel relation in a substantially vertical plane for the major portion of the distance from top to bottom of the derrick to form the rails of a guide track, the lower portions of the front legs diverging downwardly, and a travelling block dolly in the derrick mounted on said track for movement only lengthwise thereof, the front of the derrick between the track rails being open to allow stands of pipe to be moved through the track into and out of the derrick.
  • said parallel front legs are l-beams having vertical webs and front and rear flanges
  • the front ends of said side cross braces are connected to front flanges of said 7 beams
  • said rear flanges are spaced inwardly from said side cross braces
  • said beams are provided with intermediate vertical flanges spaced behind their front flanges and joined to their webs
  • said dolly including wheels on opposite sides of each beam web and disposed between the rear flanges of the beams and said intermediate flanges to hold the dolly on the track.
  • the back legs diverge from top to bottom and slope rearwardly, the sides of the derrick below its top converge forward to said track rails; and said diverging lower portions of the front legs slope forward from their upper ends.
