Definitions

  • the invention relates to a connecting device for forming a fluid supply to a rotating tool, in particular a Erdbohrtechnikzeug, with a rotary feedthrough, which has a rotor which is connectable to the rotatably driven tool, and a stator, wherein the rotor is mounted rotatably relative to the stator, and with a torque arm, which is rotatably connected to the stator and having at least one contact element, according to the preamble of patent claim 1.
  • a generic device is from the EP 0 855 490 A2 known.
  • the contact elements are resiliently mounted and radially adjustable.
  • connection device connects a drilling tool to a drive train, conveying air being conveyed to the rotating drilling tool via fixed supply lines on the drive train.
  • a star-shaped torque arm is provided on the upper part of the connecting device, by means of which the relative to the rotating drilling tool relatively fixed stator is supported with the upwardly extending supply lines relative to the borehole wall.
  • connection device can be used in each case only for the intended drilling tool with the predetermined drilling diameter.
  • the contact pressures of the torque arm on the borehole wall may be too high or too low.
  • the invention has for its object to provide a connection device that is particularly flexible.
  • the connecting device is characterized in that the at least one contact element between a retracted position and a deployed position is movable in which the contact element is extended to the torque support against the retreat position.
  • a basic idea of the invention is to provide a torque arm with extendable contact elements on a rotating tool. Due to the adjustability of the contact elements, the connection device can be used on different tools with different tool diameters. An adaptation of the torque arm takes place in this case by appropriate retraction or extension of the contact elements on the respective tool diameter. Also, when used in boreholes, the contact pressure of the abutment elements on the borehole wall can be changed and adjusted according to the requirements of the material of the borehole wall.
  • the connecting device according to the invention can also be used in boreholes with drill diameters changed in the direction of drilling. Furthermore, it is possible with the connecting device according to the invention to fold the system elements when needed, such as when retracting or extending a drilling tool when no torque support is needed.
  • the connecting device can be fixedly arranged on a tool or a drive train, for example a drill pipe.
  • a connecting strand is provided which on the one hand has a first connecting device to a drive device and on the other hand a second connecting device to the tool and that the torque arm is arranged along the circumference of the connecting strand.
  • the connecting strand can thus serve as a kind of adapter, which is arranged between the tool and the drive device, in particular a drive train or a drill pipe.
  • the connection device can thus be used flexibly on various drilling tools and drill pipes.
  • the connecting means may comprise conventional rotary joints, such as polygonal joints with pin locks, such as those used on known Kelly bars.
  • an axially movable actuator is provided and that a translation device is provided, through which a axial movement of the actuator in a radial movement of the at least one contact element can be implemented.
  • the actuator may in principle be an actuating cylinder, such as a hydraulic or pneumatic cylinder, which is arranged rectified to the rotational or drilling axis of the tool. By this arrangement, there is sufficient free space available over a possible radially directed cylinder arrangement.
  • the actuator is movable by a relative movement of the connecting string relative to the tool and / or the drive means. This can be done in particular by, for example, when a drilling tool is placed through the drill string on the ground or the bottom of the hole. Due to this axial pressure force during drilling, an axial relative movement of the actuator can be generated, so that automatically results in drilling a desired display of at least one contact element.
  • a clamping device by which the at least one contact element in the retraction position is durable. If, for example, a drilling tool is lifted off the ground or the bottom of the borehole, the clamping device causes a return movement of the bearing elements into the retracted position.
  • the clamping device may preferably have tension springs, which may be designed depending on the arrangement as compression or tension springs.
  • a particularly stable arrangement results according to the invention in that the actuator is arranged annularly on the connecting strand.
  • a further preferred embodiment of the invention results from the fact that the translation device has a lever mechanism.
  • the at least one contact element has a roller body.
  • the roller body is in contact with the environment, in particular a borehole wall.
  • a roller axis of the roller body is preferably directed tangentially to the drilling or longitudinal axis of the tool, so that when moving the torque arm in the axial direction, a rolling movement, however, to achieve the function of a torque support in the circumferential direction, a good support is achieved.
  • first connection means and / or the second connection means is formed as an axially movable rotary joint.
  • the rotary joint can be achieved in a known manner by a polygonal connection, in particular a square connection.
  • An axial securing can be achieved by a bolt directed transversely to the longitudinal or drilling axis, which, however, extends through a slot. The slot extends in the longitudinal or drilling direction. This allows an axial relative movement between the connecting strand and the tool or the drive device.
  • the proposed rotary feedthrough is formed in a basically known manner with a stator and a rotor.
  • the stator may have at least one first line connection for a fluid, which stands still in relation to an environment, for example surrounding ground, and in that the rotor has at least one second line connection which stands still relative to the tool.
  • the line connection of the stator may be a conventional hose or pipe connection for a liquid or a gas in a conventional manner.
  • the stator usually has on its inside an annular channel, which corresponds to a corresponding channel or corresponding openings on the rotor. The arrangement of corresponding seals can thus be a fluid transfer from a stationary to a rotating component.
  • the connecting line to the fluid line is designed as a hollow shaft.
  • the tubular connecting strand By one or more corresponding radial bores in the tubular connecting strand so a line connection can be made from and to the rotor.
  • an inventive connecting device 10 is shown, which along a longitudinal or drilling axis 16 has a tubular connecting strand 12.
  • an annular rotary feedthrough 20 which is also referred to as a rinsing head, and a torque arm 40 along the circumference of the connecting strand 12 is arranged.
  • the connecting strand 12 On its upper side, the connecting strand 12 has a first connecting device 14, which comprises a square hole 17 for connection to a drill string, not shown here. About appropriately transverse transverse bores 13 can be made an axial securing and connection to the drill string via retaining bolts.
  • a correspondingly corresponding square neck 18 is arranged, which has a slot 19 for axial securing.
  • the slot 19 is directed along the longitudinal or drilling axis 16 to receive a transverse pin axially displaceable.
  • the second connecting means 15 is formed as a rotary joint, which allows a connection with an axial mobility to a drilling tool.
  • the rotary feedthrough 20 allows, in a basically known manner, a fluid connection of fluid lines fixed relative to the surroundings, which are connected via a first line connection 26 to an annular stator 24.
  • the sleeve-shaped stator 24 has a central annular channel 27, which is sealed to both axially directed sides via a respective sealing ring 25 and inwardly relative to a sleeve-shaped rotor 24 rotating relative thereto.
  • the rotor 22 has a plurality of transverse radial bores on, which forms a second line connection 28 to the interior of the form of a hollow shaft connecting strand 12.
  • the interior of the hollow connecting string 12 is sealed at the top via a closing element 29, so that the interior of the hollow connecting string 12 can serve as a fluid conduit down to a drilling tool.
  • the torque arm 40 has to support the stator 24 against a borehole wall, not shown, a plurality of plate-shaped contact elements 42, on the inside of each a roller body 43 is rotatably mounted about a roller axis 41.
  • the roller axle 41 is directed tangentially to the longitudinal or drilling axis 16, so that a rolling movement of the torque arm 40 in the direction of the longitudinal or drilling axis 16 can take place.
  • the roller bodies 43 project partially through an opening in the plate-shaped contact elements 42.
  • the abutment elements 42 are mounted on a support ring 47 in a radial direction by means of upper levers 46.
  • the upper levers 46 are also pivotally connected to an upper end of lower levers 45, which in turn are supported on an annular actuator 30 and are each articulated thereto.
  • a tensioning device 34 which has two compression springs on each of the lower levers 45, the respective contact element 42 is held in a retracted position, which in FIG Fig. 1 is shown.
  • the actuator 30 When the actuator 30 is moved axially upward, the abutment members 42 are driven radially outwardly with the roller bodies 43 to contact a borehole wall to form a torque support.
  • the compression springs of the tensioning device 34 are tensioned.
  • the axial movement of the actuator 30 is effected by an axial pressing of the connecting strand 12 down to a drilling tool. This pressing results automatically in a drilling operation. In this way it is ensured according to the invention that the torque arm 40 is reliably put into operation during drilling operation.
  • the abutment elements 42 are moved from a retraction position, in which the abutment elements 42 bear against stops 48, moved radially outward into a pitching position and brought into contact with the borehole wall.
  • a highly schematic arrangement of the connecting device 10 according to the invention is shown on a drilling tool 50, which is a cylindrical core drill pipe in the illustrated embodiment.
  • a Kelly linkage or another drill string 11 can be connected in a known manner. This can be provided in a known manner with other support or drilling elements.
  • a hose reeling device 36 can be provided on the drill pipe 11 in an upper region, which allows an extension of the drill pipe 11, a corresponding extension of the fluid lines.
  • the drill pipe 11 can be coupled in a known manner with a drill drive to drive the drilling tool 50 rotationally.
