Definitions

  • the invention relates to a holding device for support of drill pipes on a drill carriage, on the a rotary drive is mounted to be longitudinally displaceable.
  • the pipe support contains one Recess for the insertion of a drill pipe and one another recess in which a reinforcing bar is inserted can be inserted into the drilled borehole after the drill pipe has been pulled out.
  • the drill pipe is inserted into the pipe support while this is in relation to the swivel arm in its working position located. Then the swivel arm into the Pipe support position pivoted without the position of the pipe support changed with respect to the swivel arm.
  • the invention has for its object a holding device to support drill pipes to create the is applicable to pipe carriages with a small width and has a simplified structure.
  • Swing arm of the Lynette parallel to the longitudinal direction the axis of the carriage pivoting the is arranged laterally next to the carriage, so that the Swivel arm swung into the side of the pipe support area becomes. So that the pipe support attached to the swivel arm does not collide with the pipe if this on the rotary drive is attached, the pipe support on the Swivel arm between one working position and one Retractable position movable. This movement of the pipe support is dependent on the pivoting movement of the Swivel arms controlled.
  • the pipe support takes its Work position only when the swivel arm Tube support position has reached at least approximately.
  • the movement of the pipe support on the swivel arm can either a swivel movement or a linear movement or a movement predetermined by a cam track be. It is important that in the retracted position of the Pipe support the radius of the swivel arm is not essential is enlarged. In contrast, this radius is in the Working position of the pipe support enlarged so that the swivel arm with the pipe support in alignment can reach under the pipe located under the rotary drive.
  • a relative In the holding device according to the invention that can Pipe support that is pivoted laterally, a relative have a large length in the direction of the pipe axis. In this way, screw tubes can also be defined be supported. With a longer length of the pipe support ensures that the pipe support is always attacks the outside of the worm gear, and not in the worm threads penetrates.
  • Another advantage is that the length of the Swivel arms for adaptation to different pipe diameters or pipe positions cannot be changed got to. Rather, it is sufficient to replace the pipe support to make it to different pipe diameters and Adjust pipe positions.
  • the holding device according to the invention is simple and easy to maintain. You can on any drill carriage outside be attached.
  • the invention is a single drive for the swivel arm and that Pipe support provided, controlling the movement such that when the swivel arm is retracted initially no movement in the pipe support position of the pipe support takes place relative to the swivel arm. A such movement is only carried out after the Swivel arm has reached the working position.
  • This sequence control the movements of the swivel arm and pipe support expediently takes place using a spring device that the pipe support towards biased to its retreat position.
  • the 1 is an elongated drill carriage 10 provided a rail guide for a feed carriage 11 forms the movable along the carriage and from a feed drive (not shown) is driven.
  • the carriage 11 carries a rotary drive 12, from which a rotatably driven Coupling end 13 to the front, that is towards the Borehole, protrudes.
  • This coupling end 13 is in the rear end of a drill string 14 from one behind the other Drill pipes screwed to the drill string 14 to rotate and simultaneously into the borehole to push in.
  • Tapping guide 15 At the front end of the drilling mount 10 there is one Tapping guide 15, which centers the drill string 14 and supports.
  • Fig. 1 the state is shown in which the drill string 14 of the rotary drive 12 as much as possible was advanced, after which the rotary drive 12 in his Treatment position was driven.
  • this situation is another drill pipe 17 behind the drill string 14 set.
  • This drill pipe 17 is on the carriage 10 with Lynetten held 18 so that its axis was in alignment with that of the coupling end 13 and that of the Drill string 14 is located.
  • the coupling end 13 of the rotary drive 12 into a thread at the rear end of the pipe 17 screwed in and the drill pipe 17 is with rotation advanced to the rear end of the drill string 14 held against rotation to become.
  • the drill carriage 10 has two vertical, with a mutual distance parallel to each other arranged beams 20,21, the upper ends of the externally projecting guide rails 22 for guiding the Form slide 11.
  • One of the bars 20 stands outwards the boom 23 of the Lynette 18.
  • On the end of the boom 23 is a hinge 24 of the Swivel arm 25 articulated, which is longer than the boom 23.
  • the swivel arm 25 has such a length that its free end just before the pipe 17 ends when the swivel arm is in the tube support position 25a. At the free end of the swivel arm 25 is via a joint 26 the pipe support 27 attached.
  • the pipe support is a two-armed lever, one of which a lever arm 271 Support jaw forms with a trough for receiving the Drill pipe 17, while moving from joint 26 to another Lever arm 272 protruding toward the side forms a control arm, on which the drive 28 engages.
  • the drive 28 consists of a linear drive, namely a piston-cylinder unit, one end of which is connected by a joint 29 attacks on the boom 23, and the other end hinged to the lever arm 272 of the tube support 27 is.
  • the joint 29 has one of the mount 10 less distance than the hinge 24, so that the drive 28 crosses the swivel arm 25.
  • a spring 30 is attached, the other end on the first lever arm 271 of the tube support 27 attacks and the pipe support in one position pulls in which the lever arm 271 is substantially rectangular is angled from the swivel arm 25 so that when the swivel arm 25 is pivoted about the joint 24 around the radius of the largest circle that the Pipe support 27 describes, is not larger than that Length of the swivel arm 25.
  • the swivel arm 25 When the drive 28 is extended, the swivel arm is located 25 in its retracted position 25b, the pipe support 27 itself, with respect to the swivel arm 25, also is in its retracted position 27b. Will the Drive 28 retracted, i.e. the piston rod in the Retracted cylinder, the swivel arm 25 is around the joint 24 pivots until it reaches the pipe support position 25a takes in which he directed against the drill pipe 17 is. On the boom 23 is an adjustable stop 31 provided against which the swivel arm in the pipe support position 25a comes across. The pivoting of the swivel arm 25 is done with a force that is less than that Preload force of the spring 30. Therefore, the pipe support remains 27 in its retracted position 27b.
