Description
- The present invention relates generally to a handling board or platform and, more particularly, to a stabbing board assembly mountable on a well derrick for supporting a worker while stabbing joints of pipe or casing during running operations.
- It is common practice in the oil and gas well drilling art to provide some form of support or platform for accommodating an operator or worker at a position above the floor of the derrick, particularly during a running of pipe or tubulars into the well, in order to assist in properly axially aligning the tubulars during the stabbing operation. Typically this is accomplished through the use of casing stabbing boards, which are hung or suspended on wirelines held within the derrick or drilling rig.
- Additionally, in the prior art, a number of devices have been developed to improve upon such hung or suspended stabbing boards. For example, U.S. Pat. No. 4,326,602 to Bryant, which is herein incorporated by reference in its entirety, teaches a portable stabbing board adapted to be attached to a rig which includes a frame member mountable with the rig and a platform adapted for vertical movement along the frame member for supporting a worker during running operations. However, the stabbing board of Bryant does not provide for any horizontal movement of the platform to allow an operator to be placed in sufficient proximity to the pipe or tubulars during stabbing operations and to easily and quickly allow the platform to move away from the pipe or tubulars when the operator has completed his task of stabbing the tubular.
- U.S. Pat. No. 2,425,302 to Calhoun, which is herein incorporated by reference in its entirety, teaches a more permanently mounted stabbing board which can be adjusted in a horizontal manner. However, the stabbing board of Calhoun is designed to be kept or locked in a fixed horizontal relation through the use of bolts (55) positioned through aligned openings (53) in both the telescoping sleeve (42) and hanger rail (40), as well as through the use of a bar (58) the end of which are receivable in eyes (60) and (62). As such, the stabbing board of Calhoun cannot easily and quickly move the platform away from the pipe or tubulars when the operator has completed the stabbing operations so as to reduce the risk of the operator being hit or injured by to the moving blocks or other equipment within the derrick.
- Accordingly, there still exists a need to for an improved stabbing board that will provide ease of platform movement in both the horizontal and vertical directions, that is stable and which is simple in design.
- The present invention provides improvements to stabbing boards and stabbing baskets.
- In one embodiment, the present invention provides a stabbing board for a rig and for supporting a worker while stabbing joints of tubular members together during running operations, comprising a frame member, a platform to support the worker, a carriage, vertical power means for moving the carriage vertically with respect to the frame member, a linkage to connect the platform to the carriage and to facilitate horizontal movement of the platform relative to the carriage and the frame member and horizontal power means for moving the platform horizontally with respect to the frame member.
- In another aspect of the invention the linkage of the stabbing board is a scissors linkage and the vertical power means comprises a leadscrew mounted within the frame member, a motor to drive the leadscrew and a nut mounted on the carriage to receive the leadscrew.
- Embodiments of the invention will now be described, by way of example only, with reference to the accompanying drawings, wherein:

The top support member 24 may also be referred to as girder locking assembly and comprises a pair oftop supports 24 a, each substantially alike and having asuitable hook 24 b formed adjacent one end thereof. Preferably, thetop support 24 a andhook 24 b are an integral unit. The top support member 24 is adapted to supportably engage the rig for supporting theframe member 12. The top support member 24 is mounted with the rig in such a fashion that the top support 24 a may extend through the rig side with a portion thereof disposed on a girder of the drilling rig. Advantageously, thehook 24 b is useful for engaging the girder of rig during installation procedures and to prevent thestabbing board 10 from falling from the rig during such preliminary placement procedures. - The rig attachment means 14 further comprises bottom locating means designated generally as 34. The bottom locating
means 34 comprises at least onearm 34 a adapted to be mounted with thelower end 12 k of theframe member 12.Multiple arms 34 a may be used, if desired. Thearms 34 a are preferably pivotally mounted to thelower end 12 k at a pivot points P. More preferably,arms 34 a are slidably mounted, usingsecurable sliding means 34 s, with and along thevertical channel members lower end 12 k thereof. This preferred arrangement of the bottom locating means 34 results in substantially universal mounting of thearm 34 a with theframe member 12 such that thearm 34 a may pivot and slide in a vertical plane with respect to theframe member 12. - The bottom locating
means 34 further includes asleeve 34 c slidably mounted witharm 34 a and movable along the length thereof as desired. Thesleeve 34 c has projectingplate 34 e depending therefrom. Appropriate securing means 34 d which may include an screwable tee handle or the like threaded through a treadable opening within thesleeve 34 c. As such, the bottom locatingmeans 34 is for locating thelower end 12 k of theframe member 12 an appropriate distance from the rig to insure a substantially vertical disposition of theframe member 12 within the rig. Thearm 34 a extends from theframe member 12 through the rig side of the drilling rig for engaging a girder thereof. More particularly, thesleeve 34 c is positioned with thearm 34 a such that the sleeve'splate 34 e engages the girder of the rig and the securing means 34 d secures the sleeve and consequentlyarm 34 a to the drilling rig upon being suitably disposed against the girder, for ease in quick mounting. - In an alternate embodiment (not shown), the stabbing
board 10 is permanently attached to the rig, such as by welding or bolting theframe member 12 directly to the rig. - The stabbing
board 10 of the present invention further comprisesplatform 16 for supporting the worker W during running operations. Theplatform 16 comprises afloor 16 f affixed to arear platform support 16 r.Rear platform support 16 r comprises a pair of vertical, substantially parallelplatform channel members floor 16 f. Top andbottom support members platform channel members rear platform support 16 r. Theplatform channel members channel troughs 16 a′, 16 b′ formed within the U-shaped channel members with theplatform channel troughs 16 a′, 16 b′ of theplatform channel members rear platform support 16 r. - Preferably, the
platform 16 further comprises asafety barrier assembly 17 to form the perimeter of a working cage for the worker W utilizing the stabbingboard 10 of the present invention. Thesafety barrier assembly 17 has appropriate braces such asvertical posts safety chain 17 c for providing a suitable barrier to safely keep worker W on the stabbingboard 10 during running operations. More preferably, theplatform floor 16 f further comprises a wire screen or metal grate (not shown) to prevent inadvertent slipping of the worker when standing on thefloor 16 f. It is preferred that therear platform support 16 r is sized such that it is of substantially the same width as thevertical channel members frame member 12. - Even more preferably, the
platform floor 16 f is pivotally connected to therear platform support 16 r, using a securable pivot means 50, to enable the platform to be folded up in a substantially vertical position, substantially paralled to therear platform support 16 r, when theplatform 16 is not in use and requires to be stowed (seeFIGS. 8 and 9 ). - The stabbing
board 10 of the present invention further comprisescarriage 22 for supporting theplatform 16 and capable of vertical movement V along theframe member 12.Carriage 22 comprises a pair of vertical, substantially parallelcarriage channel members bottom support members carriage channel members carriage 22. Thecarriage channel members carriage channel troughs 22 a′, 22 b′ formed within the U-shaped channel members with thecarriage channel troughs 22 a′, 22 b′ of thecarriage channel members carriage 22. -
Carriage 22 is slidably mounted to theframe member 12 for vertical movement V along saidframe member 12. Preferably,carriage 22 is disposed within thechannel troughs 12 a′, 12 b′ formed withinvertical channel members frame member 12. More preferably, a plurality ofcarriage rollers 22 r are provided to facilitate said slidable vertical movement V of thecarriage 22 within thechannel troughs 12 a′, 12 b′. - The stabbing
board 10 of the present invention further comprises vertical power means 18 to provide motive force for moving thecarriage 22 vertically with respect to theframe member 12. Preferably, vertical power means 18 is a leadscrew-based power means, further comprising a leadscrew 18 l (threads not shown) mounted within theframe member 12 in a vertical plane substantially parallel with the frame member, a motor 18 m to drive the leadscrew and a nut 18 n mounted on thecarriage 22 to receive and treadably mate with the leadscrew 18 l (leadscrew 18 l otherwise passing through carriage through appropriate sized openings, including openings in top andbottom support members carriage 22. More preferably, the threads of the leadscrew 18 l and nut 18 n have an Acme profile. Even more preferably the motor 18 m is an air motor or may alternatively be an electric, hydraulic or any other suitable type of motor. The carriage 22 (and theplatform 16 mounted thereto) is movable vertically along theframe member 12 upon actuation of the vertical power means 18. - Advantageously, the leadscrew-based power means is self-locking (i.e. when stopped, a linear force on the nut 18 n will not apply a torque to the leadscrew 18 l). More advantageously, the vertical power means 18 is therefore capable of holding vertical loads (such as the
carriage 22,platform 16 and any worker W positioned thereon) when the motor 18 m is turned of, thereby providing significant safety advantages over a winch and cable based power means such as that disclosed in U.S. Pat. No. 4,326,602 to Bryant. - The stabbing
board 10 of the present invention further comprises alinkage 30 to interconnect theplatform 16 with thecarriage 22 and to facilitate horizontal movement H of theplatform 16 relative to thecarriage 22 and theframe member 12. Preferably, thelinkage 30 is a scissors linkage 30 s capable of moving in the horizontal plane only and comprising laterally off-set, side-by-side scissor linkages, each scissor linkage having one or more sets of lever arms. In this embodiment, scissors linkage 30 s comprises two pairs oflever arms pin 30 p in their median part, respectively pivoting with the side edges of theplatform 16 andcarriage 22. - One of the free ends 31 a, 32 a of each of
arms pin carriage 22, each to their respectivecarriage channel members arms slider platform channel troughs 16 a′, 16 b′ of theplatform channel members FIG. 3 ). The other free ends 31 b, 32 b are thereby confined to move in a rectilinear manner, that is, with straight line motion, relative to theplatform channel members cross-member 33 separates and maintains the substantially parallel relationship of free ends 31 b, 32 b and provide for additional strength of thelinkage 30. - One of the free ends 31′a, 32′a of each of
arms 31′, 32′ is pivotally mounted about a fixedpin 31′p, 32′p secured to theplatform 16, each to their respectiveplatform channel members arms 31′, 32′, each pivot about a roller orslider 31's, 32's slidably mounted within their respectivecarriage channel troughs 22 a′, 22 b′ of thecarriage channel members FIG. 4 ). The other free ends 31′b, 32′b are thereby confined to move in a rectilinear manner, that is, with straight line motion, relative to thecarriage channel members linkage 30. - The stabbing
board 10 of the present invention further comprises horizontal power means 40 to provide motive force for actuating thelinkage 30 between an extended state (seeFIG. 2 a) and a collapsed state (seeFIG. 2 b) and, hence, move theplatform 16 horizontally with respect to theframe member 12 and, consequently, towards or away from the well center and any tubular members that may be present there. - Horizontal power means 40 may be a hydraulic ram-based means of conventional design. Preferably, however, horizontal power means 40 is a leadscrew-based power means, further comprising a leadscrew 40 l (threads not shown) mounted within the
rear platform support 16 r in a vertical plane substantially parallel withplatform channel members rear platform support 16 r to receive and treadably mate with the leadscrew 40 l and to translate the torque of the leadscrew 40 l into actuating force on thelinkage 30 to move it between an extended state and a collapsed state. More preferably, the nut 40 n integral with the pivotingcross-member 33 and allows leadscrew 40 l to pass therethrough. Advantageously, pivotingcross-member 33 pivots as scissors linkage actuates about free ends 31 b, 32 b, thereby allowing leadscrew 40 l to remain substantially parallel withplatform channel members - During running operations the worker W preferably stands on the
floor 16 f of theplatform 16 for stabbing the appropriate tubular members during such running operations. Should it be necessary that theplatform 16 be raised or lowered, the worker merely actuates the vertical power means 18. In the preferred embodiment, the worker W actuates motor 18 m to turn in the appropriate direction, resulting in either upward or downward vertical movement of thecarriage 22, and hence theplatform 16, along theframe member 12 as may be required. Should it be necessary that theplatform 16 be moved towards or away from the tubular members, the worker W merely actuates the horizontal power means 40. In the preferred embodiment, the worker W actuates motor 40 m to turn in the appropriate direction, resulting in actuating thelinkage 30 between an extended state and a collapsed state and, hence, move theplatform 16 horizontally with respect to theframe member 12 as may be required. - As will be appreciated, the stabbing
board 10 of the present invention enables a worker W to efficiently and safely accomplish the stabbing of joints of tubular members during running operations. Advantageously, by having separate vertical and horizontal power means 18, 40, and by having a scissors linkage 30 s which operates in the horizontal plane only, the stabbingboard 10 can efficiently move the worker W closer to, or farther away from, the tubular members during stabbing operations. - More advantageously, a worker W supported by the stabbing board can easily and quickly actuate the horizontal power means only, so as to swiftly move the
platform 16 away from the pipe or tubulars when the worker W appears to be at risk of being hit or injured by the moving blocks, tubulars or other equipment within the center of derrick or rig. Such movement along the horizontal plane only is preferably, as compared to say the telescoping, luffing or slewing of a boom (where there is both horizontal and vertical movement), in situations of imminent danger when a worker quickly needs to be moved away from the central axis of the derrick and to a position of safety adjacent the derrick's inside periphery. Thus, the present invention comprehends a stabbingboard 10 that is a new and useful concept not heretofore known. - Those of ordinary skill in the art will appreciate that various modifications to the invention as described herein will be possible without falling outside the scope of the invention.
