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.
Drilling machine (1) for doublehead and overlying drilling with a drill drive (2), a drilling unit (3) for guiding it during longitudinal displacement, a pipe or drill string consisting of outer (8) and inner pipes (9) as well as a drill pipe holder (10) accommodating outer and inner pipes (8, 9), which have been inserted into each other, and having several pipe depositories (11, 12, 13), with a gripper (20) transferring the pipes (8, 9) from the drill pipe holder (10) into the drilling axis and back being allocated to this drill pipe holder, characterized in that the gripper (20) is constructed rotatably about an axis (21) and axially displaceable and has a telescoping supporting arm (22), and in that the drill pipe holder (10) with its bag-shaped stationary pipe depositories (11, 12, 13) is designed and arranged in such a way that it forms a partial circle (15) around the axis (21) of the gripper (20) and at a distance to it.
Drilling machine according to one of the preceding claims, characterized in that the bag-shaped pipe depositories (11, 12, 13) have a step mandrel (39) in the drill pipe holder (39) opposite the entry end (35) for the pipes (8, 9).
Drilling machine according to one of the preceding claims, characterized in that the step mandrel (39) for the inner pipe (9) has a stopper (40) projecting further from the bag bottom (37) and is provided with pipe guides (42).
Drilling machine according to one of the preceding claims, characterized in that the step mandrel (39) is constructed in such a way that it guides the inner pipe (9) on the bag wall (38).
Drilling machine according to one of the preceding claims, characterized in that the step mandrel (39) is connected exchangeable with the bag bottom (37).
Drilling machine according to one of the preceding claims, characterized in that the gripper (20) disposes over two pincers (23, 24) at a distance to each other, securely seizing pipes (8, 9) having different diameters and being simultaneously constructed displaceably parallel to the drilling axis (7), and actuatable jointly or separately.
Drilling machine according to one of the preceding claims, characterized in that the bag (34) of the pipe repository (11, 12, 13) accommodating the pipes (8, 9) is widened forming a funnel (36) on the end lying opposite the bag bottom (37).
Drilling machine according to one of the preceding claims, characterized in that the bag wall (38) is allocated adjusting elements (41) fixing the position of the outer pipe (8).
Drilling machine according to one of the preceding claims, characterized in that the cylinders (27) allocated to the grippers (20) are constructed as 3 position cylinders with reserve stroke.
Drilling machine according to one of the preceding claims, characterized in that end or approach indicator elements or sensors monitoring the pivoting or sliding path are allocated to the individual bags (34) of the pipe repository (11, 12, 13).
Drilling machine according to one of the preceding claims, characterized in that the gripper (20) with the two pincers (23, 24) arranged at a distance is allocated one telescoping cylinder (26) each.
Drilling machine according to one of the preceding claims, characterized in that the sliding track (30) is constructed with a prismatic contour.
Drilling machine according to one of the preceding claims, characterized in that a hose guide is arranged on the sliding track (30), whereby a hose reel is connected with the outer pipe of the sliding cylinder.
Drilling machine according to one of the preceding claims, characterized in that the individual bags (34) of the pipe repository (11, 12, 13) are constructed interchangeably in the partial circle 15 or alterable in distance to one another.
Drilling machine according to one of the preceding claims, characterized in that the telescoping cylinder (26) is allocated a reciprocating oscillating motor (44) with axial displacement.
Drilling machine according to one of the preceding claims, characterized in that the reciprocating oscillating motor (44) is equipped with a angle of rotation monitoring unit (45) for positioning the pipes (8, 9)
