  • Patent number: 6702043
    Abstract: A drilling machine 1 with a drill pipe holder 10 to be operated automatically in boring as well as in pulling, disposes over a gripper 20, which is constructed rotatably about an axis 21 and beyond that also axially displaceably, and has a telescoping support arm 22. The pipes 8, 9 can be arranged, i.e. stored, inserted into one another in pipe depositories 11, 12, 13 forming a partial circle 15 and can also be pulled out of them and swiveled into the drilling axis 7 with the aid of the gripper 20. When pulling the drilling string, the pipes 8, 9 can then be individually fanned out into the pipe depositories 11, 12, 13 and then later on the outer pipes 8 can be slid over. The entire process is operated automatically with the gripper 20.
