Definitions

  • the drilling device is characterized in that a note energy unit is provided on the support frame, that the note energy unit is connected to the clamping device for releasing the clamping and that a triggering unit is provided, through which the note energy unit for releasing the clamping device can be activated.
  • a basic idea of the invention can be seen to provide the drilling device with a self-sufficient energy unit, through which sufficient energy is provided to provide sufficient energy in a sudden or unexpected disconnection of the drilling device from the external power supply to a clamping of the drilling device on Reliably solve support tube or downhole.
  • a trip unit is provided for releasing the targeted solves the tensioning device.
  • the trip unit can basically be designed so that it triggers automatically under certain conditions.
  • the trip unit is designed so that it is activated by a machine operator targeted.
  • a further advantageous embodiment of the invention is that the clamping device is electrically actuated and that the note power unit comprises an electric battery.
  • the clamping device can have an electric drive for clamping as a whole.
  • the clamping device may also have a hydraulic cylinder which is actuated by an electrical actuation of vent valves to release a clamping force.
  • the note energy unit comprises a hydraulic cylinder in which a displacer is slidably mounted, and in that the displaceable displacer is in communication with the suspension means, wherein upon application of a tensile force to the suspension means by the displacer hydraulic fluid in the hydraulic cylinder is pressurized.
  • the hydraulic cylinder with the hydraulic fluid is the hydraulic reservoir for actuating the tensioning device.
  • the hydraulic fluid in the hydraulic cylinder is only pressurized by displacement of the displacer piston due to the tensile force acting on the suspension device. This ensures particularly well that always enough energy is available. The pressure energy is built up only at the time when it is needed. This avoids a continuous load and reduces a sealing effort.
  • a boring device 10 has a support frame 12 made up of plates and vertical struts, on which a drill drive 14, which is only shown concealed, is arranged.
  • the drill drive 14 is used for rotationally driving a drill string 15, at the lower end of a drilling tool 20 is arranged with Abtragszähnen for removing soil material.
  • the first clamping device 22 is fixedly arranged on the support frame 12.
  • the annular second clamping device 26 is axially displaceable by means of axially acting actuating cylinder 30 relative to the support frame 12 and the first clamping device 22.
  • An energy supply of the auger drive 14 and the clamping devices 22, 26 and the axial actuating cylinder 30 takes place externally via power supply lines 46, which are detachably connected to a connection device 48 on an upper side of the support frame 12.
  • the power supply lines 46 are designed in particular as hydraulic lines and / or electric lines.
  • the actuating piston 55 is an axial extension of a displacer 54, which is mounted displaceably in a hydraulic cylinder 53.
  • the hydraulic cylinder 53 forms a hydraulic fluid reservoir 52 of the note energy unit 50.
  • the hydraulic fluid reservoir 52 is connected via lines, not shown, with the clamping cylinders of the two clamping devices 22, 26.
  • FIGS. 7 to 12 a modified arrangement of an emergency power unit 50 is shown in which the trip unit 58 for releasing the clamping devices 22, 26 is also formed mechanically.
  • the note energy unit 50 on the upper side of a plate of the support frame 12 has a hydraulic cylinder 53, which simultaneously forms a hydraulic fluid reservoir 52 of the note energy unit 50.
  • a displacer 54 movably mounted, which extends outwards to an actuating punch 55.
  • the hydraulic cylinder 53 is arranged centrally on the circular disk-shaped plate of the support frame 12.
  • a further embodiment of the invention is shown, wherein the note power unit 50 has a battery 56 on the support frame 12.
  • the battery 56 is connected via a controller, not shown, to a receiver 62 at an upper end of the support frame 12.
  • the receiver 62 represents a part of the trip unit 58, wherein a control signal for releasing the clamping devices 22, 26 is transmitted via a transmitter 60 remote from the drilling device 10.
  • the transmitter 60 may be located in particular on the drilling rig 100.
