Definitions

  • the invention relates to a drill pipe element or drilling tool with a drill pipe coupling with a sleeve-shaped receptacle, a pin-shaped coupling member, which can be inserted axially into the coupling receptacle to form a rotationally fixed connection, and at least one locking bolt, which is directed transversely to the axial coupling direction and is in a locked coupling position between the coupling receptacle and the coupling member extends into a locking recess, the locking bolt being mounted in a radially adjustable manner between an unlocking position and a locking position.
  • the invention further relates to a method for actuating this drill pipe coupling according to claim 15.
  • Such a drill pipe coupling is, for example, from DE 10 2011 109 001 A1 known.
  • This drill pipe coupling is often referred to as a so-called Kelly box.
  • axial locking is effected by inserting a transversely directed locking bolt into the coupling receptacle and the coupling member, so that a positive connection is achieved.
  • the known drill pipe coupling requires manual activities by operating personnel both when locking and unlocking. These are generally time-consuming.
  • the coupling arrangements can be located several meters above the ground. To operate Climbing aids or even lifting vehicles are therefore required, which is also complex.
  • work at greater heights above the ground and also in the immediate area of action of a drill pipe is problematic for reasons of occupational safety and should therefore be reduced to a necessary minimum.
  • FIG. 10 2006 022 613 A1 Further coupling devices are from the DE 10 2006 022 613 A1 , considered to be the closest state of the art.
  • a coupling device is shown between a drill drive unit and a drill pipe element or drilling tool, with the coupling device always being in the same position. This means that coupling and uncoupling can be mechanized relatively easily.
  • the known drill pipe coupling is shown with manually insertable and removable coupling bolts.
  • the drill pipe coupling of the DE 20 2005 020 729 U1 and the drilling device DE 10 023 467 C1 show locking bolts displaced by a mechanism between an unlocking position and a locking position and back.
  • the locking bolts disclosed are designed without any preload in the locking position.
  • the invention is based on the object of specifying a drill pipe coupling and a method for this, with which a particularly efficient coupling of a drill pipe is made possible.
  • the drill pipe coupling according to the invention is characterized in that a clamping device is provided with which the locking bolt is pressed into its locking position with a predetermined clamping force, and in that the locking bolt is connected to a restoring member, by means of which the locking bolt can be reset into the unlocking position when a restoring force is applied .
  • a basic idea of the invention can be seen in providing an at least semi-automatic drill pipe coupling in which the at least one locking bolt is always reliably in the locking position. This is achieved by providing a tensioning device, preferably a tension spring, with which the locking bolt is pressed into the locking position with a predetermined tension force. Unlocking can then take place via a reset member, which is operated manually or powered to move the at least one locking bolt into its retracted unlocking position or release position.
  • the arrangement according to the invention achieves fail-safe operation, in which locking is ensured even in the event of a failure of electrical energy or hydraulic energy on a drilling rig.
  • To operate the locking bolts only one direction of force application is required, namely when the clutch is to be unlocked. Locking occurs immediately through the clamping device when the respective restoring force is no longer present.
  • connections between individual drill pipe elements and in particular a connection between a drill pipe element and a drilling tool can be established and released in an efficient and safe manner.
  • a preferred embodiment of the invention is that the locking bolt is mounted in a housing and that the reset member protrudes from the housing and can be mechanically actuated.
  • the at least one housing for the at least one locking bolt is preferably attached to an outside of the sleeve-shaped coupling receptacle. This allows the drill pipe coupling to be easily operated from the outside.
  • the locking recess is located on the inner coupling member.
  • the locking bolt is rotatably mounted about its bolt axis in the housing, that the restoring member extends transversely to the bolt axis and is designed as a lever for rotating the locking bolt, and that a link mechanism is provided between the locking bolt and the housing, through which a rotational movement of the locking bolt can be converted into a movement radially to the drill pipe axis.
  • the locking bolt is cylindrical and inserted into a tubular housing and rotatably mounted therein.
  • Connected to the locking bolt is a preferably lever-like restoring member, which projects outwards relative to the housing.
  • the link mechanism has an at least partially helical groove as a link, into which a cam engages.
  • the groove-shaped link is preferably formed at least on the inside of the housing, in particular a pin-shaped cam, which is arranged on the locking bolt, being inserted into the screw-shaped backdrop intervenes.
  • the helical groove can also be formed on the outside of the locking bolt, while a corresponding pin-shaped cam is attached to an inner wall of the housing.
  • an alternative robust design of the drill pipe coupling results from the fact that the restoring member is provided with a wedge slide mechanism, through which an axial movement can be converted into a radial movement of the locking bolt.
  • the wedge slide mechanism can be designed in basically any way to effect a movement conversion of 90°.
  • the wedge slide mechanism can be arranged in particular on the outside of the coupling device or within the pin-shaped coupling member. By arranging at least one actuating surface directed obliquely to the drill pipe axis, the desired directional conversion of a movement can be achieved.
  • a particularly low-wear embodiment of an embodiment variant of the invention is achieved in that a contact element is arranged at a free end of the reset member, which is provided with a rounded contact surface. Friction can be reduced by a rounded contact surface, which preferably comes into contact with a straight counter surface.
  • the rounded contact surface can preferably also be a rotatable element, such as a rotatable cam.
  • the drill pipe coupling can be operated directly by hand by an operator.
  • an actuator in particular a linear drive
  • the linear drive can in particular be a hydraulic or pneumatic actuating cylinder or an electrically operated spindle drive.
  • a common actuator or a separate actuator can be arranged for each locking bolt.
  • the actuator can be controlled by wire or wirelessly, so that it can be easily operated by a machine operator, in particular from the machine cabin.
  • a particularly compact design is achieved in that the at least one locking bolt is mounted with the tensioning device in the pin-shaped coupling member.
  • the tenon-shaped coupling link is hollow or designed with a receiving space for the at least one locking bolt and the tensioning device.
  • the locking recess is then arranged in a corresponding manner on the sleeve-shaped coupling receptacle.
  • two locking bolts are mounted opposite one another in the coupling member and that the tensioning device is arranged in the coupling member in an axially directed manner.
  • This arrangement can in particular be combined with a wedge slide mechanism, with the clamping device and optionally a linear actuator being aligned longitudinally and preferably coaxially to the drill pipe axis.
  • transverse forces can compensate for each other through two, preferably radially opposite, locking bolts, so that a particularly stable arrangement is achieved.
  • a further advantageous embodiment variant is that the clamping device has a spring-loaded pusher with a pressure surface inclined to the drill pipe axis and that the locking bolts have inclined actuation surfaces at their inner ends, which rest on the pressure surfaces of the pusher.
  • a linear drive can actuate the same or an opposite pusher to retract the locking bolts into their unlocking position.
  • the reset member is a movable axial piston of the actuator.
  • the reset element can be directly part of the actuator or can be moved by the actuator.
  • the locking bolt For efficient closing of the drill pipe coupling by axially retracting the coupling member into the coupling receptacle, it is advantageous for the locking bolt to have a bevel on its free front side, so that the locking bolt can be pressed radially into its unlocking position when the coupling receptacle and coupling member are coupled axially. As soon as this coupling process occurs Once the locking recesses have reached the height of the locking bolts, they can return to their locking position and thus into the locking recesses due to their spring preload. This immediately results in a secure coupling.
  • the bevel on the front of the locking bolt serves to convert the axial relative movement between the coupling member and the coupling receptacle into a radial restoring movement of the locking bolt.
  • the locking bolt has a base body with a locking pawl displaceably mounted thereon, on the free front of which the bevel is formed, and that a spring element is arranged between the base body and the locking pawl, so that the locking pawl of the locking bolt is at an axial Coupling of the coupling receptacle and coupling member can be pressed radially into the unlocking position.
  • the spring element can be designed with a lower clamping force than the clamping device, so that easy locking during an insertion process is possible. To unlock, the locking bolt must be pulled back together with the base body and the pawl against the effect of the tensioning device.
  • the invention further relates to a drilling device with a drill drive for rotating a drill pipe with a drilling tool and a turntable, wherein a drill pipe coupling according to the invention is provided and the reset member of the drill pipe coupling can be actuated by the turntable.
  • the drill pipe coupling does not have to be arranged on the drill drive. Rather, the drill pipe coupling is arranged between the individual drill pipe elements or between a drill pipe element and the drilling tool.
  • the invention is characterized in that the locking bolt is pressed into its locking position by the clamping device with a predetermined clamping force and that when a restoring force is applied to the restoring member, the locking bolt is reset into the unlocking position, in which the pin-shaped coupling member is relative to the sleeve-shaped coupling receptacle can be moved axially.
