Definitions

  • the invention relates to a horizontal drilling machine, in particular for underground laying of essentially horizontal pipes becomes.
  • Such drilling rigs are mainly used in municipal, inner-city areas increasingly used as this avoids digging up the surface and thus supply lines with low costs and without Traffic obstructions etc. can be relocated.
  • Such horizontal drilling rigs generally have a chassis to which a carriage is attached. For the drilling operation, this carriage is used by the horizontal rest position at an angle at a relatively small angle brought against the ground. There is a drill drive on the carriage longitudinally displaceable, which with the respective rear end of the last tube of the Drill pipe, which consists of a large number of interconnected, in the Usually screwed, boring bars exist, is attached.
  • the boring bars are with a normal right-hand thread connected, and the direction of rotation during drilling is right-handed, so that the threads connecting the boring bars by the rotation of the drilling are pressed into each other.
  • the drill drive is usually a hydraulic motor, and with the rear end of the drill pipe by means of a drive socket connected, which always remains on the hydraulic motor of the drill drive, However, it is designed to be detachable with respect to this, since this drive connector or whose threads etc. are subject to relatively high wear and every now and then must be replaced.
  • a first boring bar with the the front end of the drill head placed on the carriage so that the The drill head comes to rest on the front, downward end of the carriage, and the rear end of the boring bar is connected to the drill drive can.
  • the drill drive is set in rotation and at the same time along the Mount moved downwards, causing the first boring bar to slant downwards the underground is drilled forward.
  • the present invention is concerned with the boring bar change, as for Driving the hole forward but also to remove the drill string from the Drilling is necessary.
  • horizontal drilling machine Since this process has to be carried out very often during drilling, Operation of the horizontal drilling machine for this a separate operator necessary. Furthermore, horizontal drilling rigs of this type are becoming increasingly popular bores are made larger in diameter, whereby the in usually six meter long boring bars becoming heavier and barely more one person can be transported and positioned.
  • the automatic boring bar change is made possible in that on the one hand First a release unit in the front end area of the carriage, usually on one fixed axial position is arranged, which - if necessary with an axially opposite spaced further clamping unit - is able to two parts of the Drill pipe that axially adjoin one another - for example, the drive connector and the rear end of the drill pipe or two in a row Boring rods of the drill pipe - their screw connection, which by the Drilling process is extremely tight, to break open. For this are in Circumferential direction of the drill pipe requires much higher forces than in can usually be applied by the drill drive.
  • the device according to the invention comprises a loading device and a correspondingly designed and arranged boring bar magazine, which automatically transfers and positions boring bars from the Boring bar magazine on the carriage enables and there exactly on the Drilling axis positioned to the subsequent, also automatic Screw the new boring bar at the rear end to the drill drive and to allow at the front end with the drill pipe.
  • the screw connections are conical or conical Attachment socket provided to still with a small deviation from the drilling axis To allow gripping of the screw connection, however, this can also only be a limited axial misalignment compared to the drilling axis, and in addition, deviations from the drilling axis make it all the stronger Damage to the threads.
  • the boring bar magazine consists of one drum or two axially spaced disks with a surrounding sleeve, in the radially outward open recesses are housed individual boring bars, if necessary in radial direction of the recess two or more boring bars behind each other.
  • the surrounding magazine sleeve is only at one peripheral point Removal position, open, and always at this point is by means of the gripper arm the loading device a boring bar from the boring bar magazine removed so that the magazine disc previously in a corresponding rotational position must be brought.
  • the gripper arm consists of several pivotable against each other Swivel arms and is on the opposite of the boring bar magazine Attached to the carriage.
  • the swivel movements of the swivel arms with each other or with respect to the carriage only take place around swivel axes running parallel to the drilling axis and are by means of hydraulic piston-cylinder units.
  • At the front end of the gripper arm is also a hydraulically operated swiveling gripper, which in is able to take the boring bar against a counter surface of the To clamp the swivel arm.
  • the individual swivel arms of the gripper arm accordingly dimensioned and arranged at a suitable location on the carriage, are sufficient only two swivel arms that can be swiveled in relation to each other around the drill rods from the removal position of the boring bar magazine to the carriage To transfer drilling axis.
  • the gripper is designed so that it not only is pivotable to prevent jamming relative to the counter surface enable, but is also retractable along the counter surface.
  • the further clamping unit that is preferably to be provided before the release unit causes not to the frictional forces of the underground part of the Drill pipe is used as the holding torque, but the holding torque is directly applied by the additional clamping unit, creating a Screwing the drill pipe into the ground is reliably avoided, which is true due to the then necessary digging very high follow-up costs.
  • the drill consists essentially of a chassis, which between two tracks 42 is attached, by means of which it can be brought into position.
  • the carriage 3 On the chassis, the carriage 3 is arranged between the caterpillars, which in Fig. 2a carries the drill drive 5 at its rear end.
  • the carriage 3 is inclined from its rear end to the front end region 21 arranged sloping so that one on the carriage 3, in particular one on the in Longitudinal direction of the carriage 3 spaced front and rear Drill guide 24 and 25 placed tube 6c of the drill string 23 also is directed obliquely downwards.
  • Such a boring bar 6c is thus along the mount with the help of Drill drive 5 driven forward and thus obliquely into the ground.
  • Drill drive 5 driven forward and thus obliquely into the ground.
  • the drill drive 5 which is usually a Hydraulic motor 27
  • drilling drive 5 and boring bar 6c are separated, the drilling drive 5 along the Mounted back, a new boring bar 6d between the old, mostly already installed in the ground, boring bar 6c and the drill drive 5 used and this drill pipe 23 now consisting of the drill rods 6c and 6d further driven 5 piece by piece into the ground using the drill drive.
  • the drill pipe 23 can be almost extend as desired and by not being discussed here Devices also underground in terms of side deviation and angle control against the horizontal.
  • FIGS. 1 and 2 is located next to the horizontal drilling machine 1, which via the lines 21 with energy, mostly in the form of hydraulic oil or power is supplied, a drum-shaped boring bar magazine 7, which the has the same inclination to the ground as the carriage 3.
  • gripping arms 12 are arranged in order to advance new boring bars when the bore is being driven to get out of the boring bar magazine 7 and on the carriage in the Boring bar magazine 7 to pick up and on the carriage in the drill pipe insert or - when removing the drill pipe from the borehole - each the rearmost, pulled-out boring bar of the drill pipe 23 from the carriage take and place in the boring bar magazine 7.
  • the front and rear drill guides 24 and 25 ensure that the Boring bars 6 are positioned when inserted on the drilling axis 28, which also for the automated connection of the new boring bar 6c to the boring drive 5, that is, the rotating drive connection 35 projecting from the hydraulic motor rear end and the front boring bar 6b at the front end necessary is.
  • the structure and function of the gripping arms 12 can be better seen in FIGS detect.
  • Fig. 1a shows the access of the gripper arm 12 to the new, still in Boring bar magazine 7 located boring bar.
  • the gripper arm 12 has the Boring bar 6d in magazine 7 reached.
  • the gripper 13 at the front End of the gripper arm 12 around the boring bar 6d still located in the magazine 7 closed and in Fig. 1d the gripping arm 12 pivots from the magazine 7 with the new boring bar 6d.
  • the gripping arm buckles until the new one Boring bar 6d has reached the drilling axis 28 and in Fig. 1f is in this position the gripper 13 on the gripper arm 12 is opened.
  • the boring bar magazine 7 has a surrounding magazine sleeve 9, which only a radial position, the removal position 34, along a slot-shaped opening has a surface line for removing or inserting a boring bar.
  • the magazine sleeve 9 thus remains at rest while inside the magazine sleeve 9 the magazine disks 8 located at an axial distance, which are coupled in a rotationally fixed manner are and in their radially introduced recesses several each Boring bars are rotated after emptying a radial opening, to always be in the removal position 34 when the drill string is propelled to have new boring bar available or when removing the Drill pipe clearance available for placing a boring bar to have.
  • the gripper arm 12 consists of only two Swivel arms, namely the first swivel arm 36, which is pivotable opposite the carriage 3 is attached, and the second swivel arm 37, which at the end of the first pivot arm 36 is pivotally attached.
  • the gripper is then again at the front end of the second swivel arm 37 13 pivotally and also longitudinally displaceable.
  • the first is Swivel arm 36 formed kinked, with the concave side towards the mount 3.
  • the second swivel arm 37 is also designed to be kinked in this form, where the kink angle is between 40 and 90 °, it is possible to Swivel angle of the first swivel arm 36 with respect to the carriage 3 and the second swivel arm 37 relative to the first swivel arm to about 60 ° limit. This makes it easy to do this Pivotal movements by means of a piston cylinder unit 32, which is hydraulically operated, and between the two towards each other pivoting parts is arranged to effect.
  • the boring bar 6d to be transported is on circular-arc-shaped tracks transported:
  • first swivel arm The adjacent parts of the first swivel arm are located here 36 and second swivel arm 37 in an extended position to each other.
  • Fig. 1a are also the laterally projecting edges of the sliding surface of the carriage 3 recognizable guide lugs of the rod actuator 5.
  • the gripper 13 can against the counter surface, which is substantially in the longitudinal direction of the front free end of the second pivot arm 37 extends, not only swung open, but also withdrawn, so that to the target position the front end of the second swivel arm 37 a boring bar 6d easily can be applied, as shown in Fig. 1b, when the gripper arm 12 with its front free end in the removal position 34, ie the opening 10 of the Boring bar magazine 7, immersed. How far the immersion takes place depends on one existing transversely to the longitudinal direction of the second swivel arm 37 Stop from which the boring bar 6d located in the magazine 7 rests.
  • Fig. 1c the gripper 13 - also with the help of the second Swivel arm 37 mounted piston cylinder units 32c closed, that is Push the piston rod of the piston cylinder unit 32c first so far advanced until the gripper 13 is at the height of the pipe 6d to be gripped is located and then against the counter surface 14 on the swivel arm 37 pivoted and thus the tube 6d form-fitting between the gripper and the counter surface 14 added.
  • the transition from the shifting movement for the pivoting movement of the gripper 13 takes place automatically by the length of the Sliding path for the gripper 13 positively, preferably adjustable, is limited, as can be seen better in the detailed illustration in FIG. 4.
  • the gripper arm 12 by Actuation of the hydraulic piston 32a is pivoted along the circular arc 43 until to the crossing point between the circular arc 43 and a second circular arc 48, as seen in Fig. 1d.
  • the circular arc 48 is the circular arc which runs through the drilling axis 28 and the center of which is the axis 38 which the pivot arm 37 pivots relative to the pivot arm 36 can be.
  • the boring bar 6d is along the circular arc 48 on the drilling axis 28 pivoted by actuating only the second piston-cylinder unit 32b must, and compared to the stationary swivel arm 36, the second swivel arm 37 is pivoted by approximately 50 °.
  • the Gripper 13 opened by actuating the hydraulic piston 32c, that is swung open and withdrawn. This withdrawal is important because - how to recognize in the transition from Fig. 1f to Fig. 1g - it only by Retraction of the gripper is possible, the gripper arm 12 by pressing again the piston-cylinder unit 32b, the second swivel arm 37 again in the position of Fig. 1d can be moved back, as shown in Fig. 1g, without the Gripper 13 with the on the drilling axis 28, that is, the front and rear Drill guides 24 and 25, stored boring bar 6d remains hanging.
  • the gripper 13 To this 1f, the gripper 13 must be opposite the second swivel arm 37 withdrawn so far that the front free end of the gripper 13th at least by the radius of the boring bar 6d used from the circular arc 48 is removed.
  • the drill drive can be put back into operation, that is the drill drive 5 with the hydraulic motor 27 the drive connector 35 in rotation offset, which transmits this rotation to the new boring bar 6d and thus the boring bar 6d drives forward into the ground until the boring drive 5 reaches the front end region 21 of the carriage 3, as shown in FIG. 2b.
  • the gripping arms 12 are also folded up, that is to say outside the area the carriage 3, shown.
  • the drill drive 5 is first switched to free running, that is to say Use of a hydraulic motor 27 is usually a bypass, not shown opened in order to be able to turn the hydraulic motor 27 freely with little force.
  • the clamping unit 26 holds the rear end by means of hydraulic clamping jaws etc. of the drill pipe 23 by means of frictional rotation relative to the carriage 3.
  • the Release unit 4 on the other hand, can not only clamp the drive connector 35, but also turn backwards by a certain angle. The same happens when the drill string 23 is removed from the borehole instead of with the drive socket 35 with the front end of the rearmost boring bar Drill pipe 23.
  • the function of the release unit is based on the detailed representation 3, which shows the release unit 4, explained.
  • the release unit 4 consists of at least one, preferably two axially in the direction of the drilling axis spaced annular guides arranged coaxially to the drilling axis 28 30, which are fixed on the carriage 3.
  • the front end When removing the drill pipe, the front end may have to be added the rearmost boring bar that has just been loosened in turn into the loosening unit 4 introduced and by clamping and rotating the release unit 4 in the other Direction in the rearmost boring bar 4 can be released from the drive nozzle 35.
