Definitions

  • Gripping device and pipe handling system comprising at least one gripping device
  • the invention relates to a gripping device for tubular elements, and to a pipe handling system for a platform comprising one or more gripping devices. Background of the invention
  • Pipe handling apparatuses are used in a number of applications today.
  • a gripping device as described herein is particularly useful on a platform deck, both onshore and offshore, for handling different pipes.
  • Pipe handling apparatus are normally used for a number of operations on a platform deck, for example, as a component in a so-called vertical pipe racker (VPR) and stand builder tool (SBT), which operations may comprise:
  • VPR vertical pipe racker
  • SBT stand builder tool
  • gripping rollers exist where the rollers are arranged with an axis of rotation that will be parallel to the pipe held in the gripping roller, for example, power tongs etc.
  • Standard pipe handling lifting heads and pipe handling guide heads used today consist as a rule of either:
  • the lifting head can be hoisted up and down and is positioned between the guide heads.
  • the lifting head is usually equipped with a gripping claw provided with dies and a gripping claw provided with gripping rollers.
  • Vertical pipes e.g., a stand
  • a pipe cannot be rotated when the gripping claws are clamped around it.
  • the pipe With just the gripping roller claw in place, the pipe can be held up (lifted) whilst it is rotated. This is usually used when screwing pipes onto the rest of the drill string/casing and is not intended for transport, only for screwing together pipes.
  • a pipe handling head for stand building The task of this pipe handling head is to bring pipes from a horizontal position close to the drill floor (from a tubular feeding machine (TFM)) into a vertical position with head hoisted up to about 12- 15 m above the drill floor.
  • This head must be such that the pipe can freely slide through and be allowed rotation whilst the dies embrace the pipe.
  • the head should also be able to lift the pipe in that the larger diameter at the end of the pipe cannot pass through the head, or, in other words, pass through the dies.
  • the head hangs below the lifting head at the end of an approximately 6 m extension, but everything is removed once stands are no longer to be built.
  • the head, including the 6 m extension is called a stand builder tool (SBT).
  • US 201 1/0148133 Al relates to a gripping assembly for handling pipes.
  • the gripping assembly consists of two gripping members which are brought into gripping engagement with the outer circumference of a pipe.
  • the opening of the gripping members, or the distance between them, defines the size of the gripping opening and is adjusted by a locking body.
  • the locking body has a diameter that varies along the length of the locking body, and by choosing the diameter that is to be brought into engagement between the two gripping members, the size of the gripping opening is determined.
  • WO 02/074495 Al relates to a gripping claw for tubular goods comprising two in respect of each other pivotable jaws and a working cylinder that effects motion of the jaws in respect of a stationary housing.
  • a counter block is arranged between the jaws in the housing, and each jaw is by forced motion movably arranged in respect of the counter block. The movable forced motion causes axial forth and back displacement simultaneous with the opening/closing of the jaws.
  • the present invention provides a gripping device capable of gripping about a pipe, and maintaining the grip at constant pressure, whilst allowing the pipe both to rotate and be raised/lowered, "climb", without loosening the grip.
  • the invention can be used on different pipe handling apparatus, for example, apparatus such as a vertical pipe racker (VPR) and stand builder tool (SBT).
  • VPR vertical pipe racker
  • SBT stand builder tool
  • the invention is defined by a gripping device for a tubular element, comprising: at least two with respect to each other oppositely arranged gripping arms, the arms together forming an opening of a given diameter;
  • the gripping arms are configured for synchronous motion about a centre axis running through the opening
  • each of the gripping arms is configured with at least one roller, which at least one roller has an axis of rotation that forms an acute angle a relative to the centre axis of the opening.
  • acute angle should be understood to mean an angle of between 0° and 90° relative to the centre axis of the pipe opening.
  • Both the rollers and the axis of rotation of the rollers should have such an angle that they "make contact with” a pipe held in the gripping device at an angle different from 0° and 90° (and 180° for the axis of rotation of the rollers) when the rollers (and the axis of rotation of the rollers) are projected onto the centre axis of the pipe.
  • the gripping device allows the angle that the rollers and the counter rollers form with the centre axis of the opening to be adjusted.
  • it will be possible to adjust the angle between 0° and 90°, but according to the first embodiment of the invention, there is allowed a +/-5 0 adjustment of the rollers' angle a relative to a centre axis of a pipe held in the gripping device. It is basically not necessary to have an adjustment possibility of more than +/- 5° because the pitch of the pipe threads seldom exceeds this angle.
  • the adjustment mechanism for adjusting the angle a can in an embodiment comprise an adjusting screw that moves the support for the rollers horizontally in suitable grooves in the gripping device.
  • the adjustment can be automatic or manual, but will preferably be manual as it is not expected that adjustment will have to be made frequently.
  • the adjustment mechanism can comprise a crescent-shaped attachment with angle reading, where the adjusting screw can be screwed tight manually at a desired angle.
  • the angle a between the axis of rotation of the at least one roller and the centre axis of the opening will be a compromise between accuracy of height adjustment and the speed at which the pipe will be raised/lowered in the gripping device.
  • the smaller the angle a that is to say, the closer the angle a is to being parallel to the centre axis of the opening), the faster the raising/lowering will be able to take place, but at less speed.
  • the closer the angle a is to being perpendicular to the centre axis of the opening the slower the raising/lowering will be able to take place, but with greater accuracy.
  • a normal compromise, according to a second embodiment of the invention, will be about 45°, but the angle a can be both larger and smaller than this, depending on what properties it is desirable for the gripping device to have. Therefore, according to the second embodiment of the invention, the angle a can be between 0° and 90°, for example between 30° and 60°, and even more preferably about 45°.
  • the gripping device can further comprise at least one counter block part, where the counter block part comprises at least one set of counter rollers having an axis of rotation at the same angle a, alternatively an angle +/-90 0 , relative to the axis of rotation of the at least one roller.

  • the rollers and the counter rollers can be arranged in two groups, where a first group comprises at least one roller and one counter roller having one angle a, whilst a second group comprises at least one roller and one counter roller having another angle different from the angle a of the first group.

  • All the rollers both those on the gripping arms and the counter rollers, will, according to the first embodiment of the invention, be able to have such an adjustment possibility as to allow the angle of the axis of rotation of all rollers to be the same relative to the centre axis of the pipe held in the gripping device.
  • Figures 1A- 1 C show a first embodiment of the gripping device according to the invention, where the axis of rotation of the rollers forms an angle that can correspond to the pitch of the threads on a pipe;

  • the adjustment mechanism 20 for adjusting the angle a can in an embodiment comprise an adjusting screw that moves the support of the rollers/counter rollers in a suitable groove (not shown) on the gripping arms 2a, 2b and the first and second counter rollers 1 1a, l ib, 1 1 a' , 1 lb'.

  • the angle a is approximately 45° relative to the centre axis of a notional pipe 6 that is held in the gripping device 1 , but can be larger or smaller depending on the operation that is to be carried out.
