  • the invention relates to a device for releasably connecting a drill pipe to a rotary drive according to the preamble of claim 1.
  • rotary drilling rigs with a rotary drive that moves the drill pipes for example a power turret
  • the connection of individual drill pipes, the length of which can be 6 to 8 m, to form a drill pipe string of the required length and the connection of a new drill pipe to be attached to the rotary drive is usually carried out using threaded bolts.
  • a worker has to climb a ladder to the connection points, ie at a height of about 6 to 8 m, and screw the bolts into the aligned openings of the drill pipe and rotary drive. Since several connection points are arranged on the circumference of the rotary drive and the pipes, the diameter of which can be 600 to 1,800 mm, this ascending and screwing in of the threaded bolts has to be repeated correspondingly often.
  • a drive device for piping systems in which the connection and disconnection between an upper end of the drill pipe and a form-fitting rotary drive takes place with the aid of radially displaceable coupling pins.
  • These pins are automatically adjusted by a guide device in connection with a servo drive.
  • the adjustment can be made via an angle lever or a working cylinder, the piston rod end of which forms the coupling pin.
  • the construction which is complex in terms of construction and maintenance, is relatively susceptible to faults in rough construction operations, where impact, impact and dirt affect the functional safety of the numerous moving parts.
  • the invention has for its object a relatively simple device for releasably connecting a To create a drill pipe with a rotary drive, the manufacture, maintenance and use of which are connected with little effort, so that, in particular, working time in the borehole piping can be saved.
  • the device is intended to avoid the dangerous climbing and handling of the ladder by the operating personnel of the drilling device at great heights.
  • the basic idea of the invention is to connect and disconnect an upper end of the drill pipe with the rotary drive or from the rotary drive from the ground by applying a torque to a transmission device bridging the distance from the ground to the rotary drive at the upper end of the drill pipe Connection opening on the rotary drive fastened connecting device with the actual connecting element is transmitted.
  • the connecting element which can be moved radially into the aligned connecting openings of the upper drill pipe and when released from these openings, is adjusted if there is a detachable connection between the transmission device and the connecting device on the rotary drive, which advantageously consists of a ring projecting radially from the connecting device and a positive and non-positive connection in this ring insertable hook at the upper end of the transmission device, is produced and the transmission device is subjected to a rotary movement, for example by actuating a crank arranged at the lower end.
  • the transmission device for example a crankshaft, with at least one telescopic section. It may be expedient to design the entire transmission device as a telescopic shaft. This length compensation simultaneously simplifies the handling and storage of the transmission device.
  • connection between the crankshaft or telescopic shaft and the hook is designed to be angularly movable in order to ensure the torque transmission to the hook inserted into the ring of the connecting device.
  • a steel cable for example a steel wire wound like a helical spring, is arranged between the crank rod, possibly with a telescopic section, and the hook instead of an angularly movable joint.
  • the steel cable of predetermined flexibility is expediently embedded in a wire jacket or in a leather hose.
  • crankshaft or telescopic shaft slide around the entire transmission device in a tubular section which is expediently arranged near the lower end hold when operating the crank.
  • the connecting device according to the invention which is fastened to the rotary drive or in the wall of the rotary drive in the area of the connection openings and protrudes radially outwards, for example by welding, consists of a cylindrical housing, expediently of an annular cross section, in which a plug pin is rotatably and axially to the housing axis as a connecting element and is thus arranged to be displaceable radially to the drill pipe and rotary drive axis.
  • the non-rotatable guidance is advantageously carried out with a groove that runs parallel to the housing axis in the inner surface of the housing, and a feather key arranged in the plug pin, which is slidably guided in the groove.
  • the longitudinal expansion of the groove depending on the position of the feather key in the plug pin, causes its maximum displacement into or out of the connecting openings of the rotary tube.
  • this displacement of the plug pin in or out of the connection openings of the rotary tube with the aid of a device which can be observed by the operating personnel at the lower end of the transmission device.
  • this can be a screw arranged in the housing of the connecting device or a threaded pin which, depending on the displacement of the plug pin, becomes visible or slides into a recess that becomes free.
  • This display device can advantageously have a particularly striking color coding.
  • a display element could slide in a recess and be moved in the direction of the rotary drive with the displacement of the plug pin, where it comes to rest in the final state.
  • the plug pin In the axial direction and starting from an end facing away from the rotary drive, the plug pin has a blind hole-like cavity which is provided with an internal thread.
  • a pivot pin is screwed into this cavity, which is rotatably supported with an area protruding from the plug pin and is supported in the housing.
  • a region of the pivot pin which extends up to a housing cover has an outer surface which is advantageously aligned with the housing.
  • a ring expediently in the form of a ring, is formed on this outer surface with an inner opening receiving the hook of the transmission device.
  • Devices are advantageously installed in the areas of the connecting devices as protection against mechanical damage, which devices can be designed, for example, as a wiping bar and are welded to project above the connecting device and in the lateral and radial directions.
  • the advantages of the device according to the invention with a transmission device for the torque that can be actuated from the ground and a connection device attached to the rotary drive for each connection opening are that the dangerous climbing of conductors and handling at heights of 6 to 8 m above the ground can be avoided.
  • the handling of the device which is relatively simple in terms of construction, is inexpensive, the time required for the connection or disconnection process is low, so that good drilling progress is made possible.
  • the maintenance of the entire device is unproblematic as well as the storage of the transmission device, which only has to be hooked into the respective connecting device only for connecting the drill pipe and rotary drive or for releasing.
  • FIG. 1 shows a transmission device 1 as part of a device according to the invention for releasably connecting a drill pipe and a rotary drive.
  • a manually operated crank 3 with a handle 5 is arranged, the rotational movement of which is transmitted via a telescopic section 7 to a soldered steel cable 9 and to a hook 11, which is also fastened to the cable 9 by soldering.
  • telescopic section 7 two tubes are shown as telescopic section 7; the number of telescopic tubes depends on their length and the length of each Drill pipes dependent, which must be connected to a rotary drive for the production of drill pipe strings.
  • a tubular sleeve for holding the transmission device 1 while the crank 3 is rotated with the other hand.
  • Fig. 2 shows a schematic plan view in the axial direction of a connecting device 20, which is designed as a rotary plate part of the entire connecting device according to the invention in the form of a circular cylinder and on the housing 26 of which there is a device 42 indicating the connection of the drill pipe with a rotary drive 15.
