Definitions

  • the invention relates to a device device for implementable vertical support of drill pipes, consisting of a plurality of successively arranged via connecting elements coupled pipe segments, for use on drilling platforms with a releasable support on the drilling table for inserting and pulling out of drill pipes, wherein the drill pipe a holding element for releasing or connecting the connecting elements of the pipe segments and handling is connected by winches and the holding element in the form of an annular body on the drill pipe is placed and in the outer region elements for connection to the winch and the interior of the holding element for receiving the drill pipe vertically adjustable segments as jaws to Has change in the receiving diameter with a cylindrical receiving area.
  • Such arrangements are used in the field of offshore drilling platforms to connect or disconnect the plurality of pipe segments arranged one behind the other and connected to one another via connecting elements. It is known to turn holding elements into the end of the pipe segment for handling, to attack via corresponding connections to a wind above the pipe end arranged to make or break the connection between adjacent pipe segments.
  • the drill pipe is additionally supported on the drilling table in order to prevent slippage and the resulting sinking of the drill pipe into the water.
  • the object of the invention is to provide a simple design of a retaining element, which ensures a secure fixation of the pipe segment without pipe shoulders or attachment pieces with the required security and the holding forces are automatically adjustable by the weight of the coupled pipe segments in the annular body of the holding element.
  • the adjustable segments have a conical outer contour and are guided via a corresponding conical guide in the annular body of the holding element displaceable for changing the diameter of the receiving opening, wherein associated by the vertical adjustment of the segments relative to the annular body of the holding element by means of above the segments controllable actuating cylinder on the holding element for narrowing the receiving opening a clamping holder of the recorded drill pipe is adjustable, wherein the actuating cylinder attack via formed ribs in the outer region of the segments and the ribs of the segments with corresponding ribs of the annular body of the holding element receive a guide rod for holding a tensioned compression spring between leads to the ribs.
  • actuating cylinder arranged on the annular body of the holding element acts via a sleeve in each case on a rib of the segment for adjustment.
  • a simple design is achieved in that the adjusting elements for the adjustment of the segments are formed by arranged on the annular body compressed air cylinder.
  • the arranged compressed air cylinders are coupled together as adjusting elements for the segments.
  • the receiving surface of the segments for the drill pipes by inserted clamping elements having contact surfaces in the form of a sawtooth profile.
  • the holding element is designed as a hinged and lockable ring body.
  • a holding element 1 for receiving a drill pipe not shown in the form of a pipe segment is shown as a hinged ring body.
  • This annular body 1 is formed by two hinge-like pivotable elements 2 and 3, which are closable and lockable after wrapping a pipe segment.
  • the retaining element it is possible to form the retaining element as a closed annular body 1 and to receive it on a pipe segment via a central receiving opening 4.
  • the receiving opening 4 is to be adjusted in its cross section over four segments 5, wherein the segments 5 are formed as acting on the recorded pipe segment clamping jaws and vertically adjustable.
  • the segments 5 have a conical outer contour 6 and a corresponding guide 7 in the annular body as a holding element. 1
  • the segments 5 are held via a guide rod 8 in the annular body 1, wherein the guide rod 8 are held by ribs 9, 10 on the segment 5 and the ring body 1.
  • segments 5 pneumatic actuating cylinders 11 are arranged, which are controllable via lines 12 and the segments 5 vertically down through an intermediate sleeve 13 and cause a reduction of the receiving opening 4 on the conical surfaces 6 and 7 and perform a clamping action on the recorded pipe segment ,
  • the actuating cylinder 11 with the intermediate sleeve 13 act on the ribs 9 of the segments 5 a.
  • a tensionable compression spring 14 between the ribs 9, 10 of the segment 5 and the retaining ring 1 on the guide rod 8 is arranged.
  • the actuating cylinder 11 are fixed via a housing 15 on the ring element 1.
  • the cylindrical receiving surface of the segments 5 for the drilling segments is formed in this embodiment by inserted clamping elements 16 with sawtooth.
  • a winch is arranged above the ring element 1 with the recorded drilling segment, which engage on both sides on the ring element 1 via elements 17 as a receptacle for shackles 18 or the like, as in Fig. 2 is indicated.
