Definitions

  • the invention relates to a preferably mobile drilling device, in particular deep drilling device, according to the preamble of claim 1.
  • a drilling device is formed with a platform and two mutually parallel mast columns, which are arranged on the platform.
  • Such a drilling apparatus which has a double mast with two parallel mast columns, is from the US Pat. No. 7,152,672 B1 known. Between the two mast columns of the known device, a rope bottle for handling a drill string is provided.
  • the two mast columns of US Pat. No. 7,152,672 B1 are pivotally mounted on top of a platform. The spaced arrangement of the two mast columns makes it possible to pivot the mast when pivoting in a horizontal transport position via two drums provided on the drilling device, so that the two drums come to rest between the two mast columns.
  • the GB 2 081 342 A describes a drilling device with a pivoting single mast.
  • This single mast has only a single mast column, which is designed as a truss mast.
  • the working platform in plan view is U-shaped, wherein the mast between the two legs of the U-shape is swung.
  • the US 2005/0193645 A1 and the US 2005/0194189 A1 disclose drilling devices with a single mast which bifurcates in a lower region. In the area of the bifurcated branch, the mast is pivoted on a platform.
  • drills with swiveling single masts which thus have only a single mast column, are from the CA 2 555 858 A1 , of the WO 2007/022300 A2 and the US 2004/0211598 A1 known.
  • the US 2003/0121230 A1 describes a lifting scaffold for a mast platform.
  • the object of the invention is to develop a generic drilling device with double mast so that a particularly high reliability and reliability is given.
  • the drilling device according to the invention is characterized in that the mast columns project both above the platform and at the bottom of the platform over the platform, and that the platform extends into an area between the two mast columns.
  • a basic idea of the invention resides in a double mast which does not stand up on the platform but in which the working platform is displaced upwards in relation to the mast base along the mast in the direction of the mast center or even beyond.
  • the platform projects at least partially into an intermediate region between the two mast columns.
  • the platform protrudes through the two mast columns.
  • the working platform thus separates a lower mast area from an upper mast area.
  • This separation is given in particular between the two mast columns, ie in an area in which usually runs the drill pipe and appropriate operating activities are carried out.
  • the separation is particularly advantageous when drilling must be expected with sudden gas outbreaks.
  • the increased arrangement of the platform on the one hand in a particularly simple manner allows the arrangement of a blowout preventer below the platform.
  • the platform itself has a protective function for the upper pole area, in which the working area can be provided for handling the drill string.
  • the arrangement according to the invention is particularly advantageous with regard to the absorption of force.
  • extending below the mast mast column sections support the platform in a particularly simple and reliable manner on the ground.
  • the torques occurring at the connection between the mast and the platform are particularly low, since this connection is comparatively close to the center of the mast and thus at the center of gravity of the mast.
  • the platform may be provided at a height corresponding to about one third of the total height of the mast columns.
  • the platform may be positioned in an area that is between one quarter of the height of the mast columns and half the height of the mast columns.
  • the platform expediently runs perpendicular to the two mast columns.
  • the two mast columns are expediently arranged eccentrically with respect to the drilling axis of the drilling device. It is particularly preferred that the drilling axis runs between the two mast columns and / or that the two mast columns and the drilling axis lie in a common plane. As a result, the lever forces of the drill string occurring during drilling can be kept small on the mast columns.
  • a handling device for the drill string for example a cable bottle, a pulling device and / or a rotary drive
  • a free space is formed between the mast columns, in which the handling device along the mast columns is movable.
  • the handling device can follow the drill string axially and in particular serve for the axial pulling of the drill pipe.
  • At least one pivot joint is provided on the two mast columns, with which the mast columns between a vertical operating position and a mounting position are pivotable.
  • This embodiment makes it possible to spend the mast columns for transport and assembly / disassembly in the mounting position in which the mast columns preferably extend at least approximately horizontally and thus the clear height of the device is reduced.
  • the pivot axis of the pivot joint preferably extends horizontally.
  • a particularly low design effort is given by the fact that the pivot joint is arranged on the platform.
  • the pivot joint is provided on the one hand on the platform and on the other hand on the mast column, so that the pivot joint connects the platform with the mast column.
  • the design effort can be further reduced by the fact that the pivot joint is spaced from the foot of the mast columns. In this way, it can be considered that the platform in the vertical operating position is spaced from the foot of the mast columns.
  • each of the two mast columns has at least one pivot joint.
  • At least one linear drive in particular a hydraulic cylinder, is provided for pivoting the mast columns.
  • this linear drive is advantageously articulated on the one hand to a mast column and on the other hand to the platform.
  • Each of the two mast columns preferably has at least one own linear drive for pivoting.
  • the linear drive extends at least partially below the platform.
  • the linear drive runs completely below the platform.
  • the linear drive is articulated in a region of the mast column which is lower than the platform in the vertical operating position of the mast column.
  • a further preferred embodiment is that, in particular in a head region of the mast columns, at least one transverse strut is provided, which connects the two mast columns. In this way, an undesirable relative tilting of the two mast columns against each other can be prevented.
  • a space between the two mast columns is given below the cross member, which extends to the platform. In this space, the handling device may be provided.
  • Another cross connection between the two mast columns may consist of the platform, which is connected via the pivot joints with two mast columns.
  • Another cross connection can exist in the foot area of the mast columns.
  • the versatility can be increased with high reliability by providing a drilling carriage, which is mounted longitudinally displaceable on the two mast columns.
  • the handling device can be provided on this drilling carriage.
  • the drilling carriage is arranged in the upper mast area above the platform.
  • the drilling carriage has two guide sleeves, each surrounding a mast column, and a transverse strut extending between the guide sleeves.
  • This transverse strut can be designed in particular in the form of a yoke, that is to say have a medium taper.
  • a further preferred embodiment of the invention is that for longitudinal displacement of the drilling carriage at least one linear drive, in particular hydraulic cylinder, is provided.
  • the linear drive preferably runs parallel to the two mast columns.
  • the linear drive may be fastened on its side facing away from the drilling carriage on one of the mast columns, in particular in its foot region.
  • a corresponding eye can be provided on the mast column.
  • the linear drive extends at least partially below the platform, whereby a particularly large carriage stroke can be given.
  • the hydraulic cylinder is designed as a double cylinder and has two individual cylinders, which act in opposite directions and which are connected to each other at their cylinder housing.
  • oppositely directed effect can be understood, in particular, that the piston rods of the two individual cylinders protrude on opposite sides of the cylinder arrangement.
  • the linear drive is preferably arranged on a mast outside of a mast column, wherein the mast outside of the other mast column and / or the gap between the two mast columns facing away. It is particularly expedient that two linear drives are provided, each on a different guide sleeve and / or mast column are arranged. As a result, undesired tilting of the drilling carriage can be prevented.
  • a particularly high rigidity of the mast can advantageously be achieved according to the invention in that at least one of the mast columns has a rectangular, in particular square outer cross-section or has an H-profile in the outer cross-section. Furthermore, it is particularly advantageous for at least one of the mast columns to have full-surface outer surfaces along the longitudinal side. In principle, however, the mast columns can also be designed with a truss structure.
  • the assembly work can be further reduced by the fact that for lifting the platform at least one mast, in particular a parallelogram mast, is provided.
  • a parallelogram-shaped mast has an approximately parallel to the platform extending base and two mutually parallel support arms, which connect the platform with the underlying base.
  • a particularly stable drilling device can be obtained by providing at least two masts. These two masts are preferably arranged side by side with aligned pivot axes.
