Definitions
- Hydraulic piping machine as attachment for one
- the invention relates to a hydraulic piping machine as an attachment for a mobile rotary drilling system for producing cased bores for piles or wells by means of so-called dry rotary drilling tools with a hydraulically height-adjustable base body, with fixed support brackets, and a flexible linkage connected to the undercarriage of the excavator and one Hydraulic-mechanical clamping device rotatably mounted in the base body for transferring the drive torque to the drill pipes.
- the rotary drive - also known as the power turret - is adjustable in height on a drilling mast, which transmits the torque required for drilling directly to the drill pipe via a pipe adapter. The torque can be increased by switching on another drive motor.
- the increased torque is not sufficient to turn the drill pipes into the control depths.
- An even greater increase in the drive torque in the power turret would lead to overloading of the drilling mast and the superstructure.
- oscillating casing machines are used in which the drill pipes are at an angle of rotation of about 25 ° to 30 ° back and forth.
- Practice has shown that drill pipes can be screwed in faster and with respect to the torque more easily with the same earth resistances than those that are only moved back and forth over a short distance, i.e. in an oscillating manner, especially when harder ground layers, e.g. B. light rock, must be driven through.
- the object of the invention is to provide a rotating hydraulic piping machine with a hydraulic-mechanical tensioning device in connection with a rotary drilling system, which does not require its own hydraulic drive in order to screw in drilling pipes to greater depths. It is essential to the further object of the invention to design the piping machine in weight and height in such a way that it can be used, transported and implemented as a closed, movable unit with the rotary drilling rig, and above all that through the interchangeably combinable drive units, either the drill pipe transmissible torque can be adapted to the locally prevailing earth resistance or increased if necessary.
- the invention is based on a known hydraulic piping machine as an attachment for a mobile rotary drilling rig with the features mentioned at the beginning, and it comprises as a first solution to the problem described above a torque-increasing, a drive or chain sprocket containing power transmission between the in
- the invention comprises a torque-increasing power transmission gearbox containing a drive or chain sprocket between the hydraulic-mechanical tensioning device rotatably mounted in the base body and a KellyBox mounted in a mounting housing attached to the base body as a releasable connecting means to the drive or chain sprocket
- a counter-adapter can be used for a connection adapter which is connected directly to a power head which can be raised and lowered on a drilling mast, so that the torque of the power head can be increased to the hydraulic-mechanical clamping device which clamps the drill pipe.
- the torque of the power rotary head is passed into the piping machine according to the invention and converted there into a larger torque.
- This can be done via the Kelly rod (drill pipe) or via a connection adapter.
- the torque can also be transmitted via a connection adapter instead of via a Kelly rod.
- the Kelly box is arranged in the attachment housing attached to the base body, and this is used with a counter adapter for the connection adapter that is directly connected to the power swivel head that can be raised and lowered on the drilling mast, so that the torque of the power swivel head is transferred to the hydraulic-mechanical clamping device that clamps the drill pipe.
- a gear drive as a toothed ring / toothed pinion pair or a chain drive as a chain toothed ring / chain pinion pairing can be used as the power transmission gear.
- the Kelly rod or the connection adapter can be brought into engagement with the Kelly box of the casing machine; the incoming torque is then converted into a larger torque with a lower number of revolutions within the base body of the casing machine by the power transmission gear and transmitted to the drill pipe.
- the drill pipe can also be drilled to greater depths or through harder ground layer Bring in fully rotating without the need for a separate hydraulic drive for the piping machine. Only the torques coming from the power turret and from the drill rod or the Kelly rod are used.
- connection possibility for the parts of the power transmission, such as the drive pinion or sprocket, and the attachment housing enclosing the Kelly box are provided on both sides of the base body of the piping machine; the drill rod or the Kelly rod can then be brought into engagement either on the left or right of the base body, as seen from the carrier vehicle.
- the free-standing connection for this attachment housing can be used advantageously for attaching a plastic lubrication pinion.
- the base body of the piping machine according to the invention is preferably connected to the undercarriage of the rotary drilling system by a linkage. This can be done, for example, by means of hydraulically adjustable telescopic rods or mechanical telescoping, which act on both sides of the base body.
- a further third embodiment of the invention for solving the task described above in a generic piping device comprises a) a torque-increasing, a drive or chain sprocket power transmission gear between the hydraulic-mechanical tensioning device rotatably mounted in the base body and a mounting housing attached to the base body as Detachable connection means to the Kelly box drive or chain sprocket, which can be exchanged for an attachable hydraulic gear motor that can be connected to the drive or chain sprocket, which means
- Hydraulic line connections are connected to the hydraulic drive systems of the drive motor of the excavator, and b) coupling of the connection adapter connected to the power rotary head, which can be raised and lowered on a drilling mast, to a pipe adapter connected to the drill pipe.
- This form of training can also be produced in a simple manner by replacing the interchangeable Kelly box with a hydraulic geared motor, the hydraulic supply of which can be produced by connecting the excavator to the hydraulic auxiliary system.
- a hydraulic geared motor the hydraulic supply of which can be produced by connecting the excavator to the hydraulic auxiliary system.
- the powerful energy source of the traction motor is used to transmit torque to the drill pipe.
- a connection for an attachment housing for receiving a toothed or chain sprocket is provided on both sides of the base body, then a hydraulic motor can also be connected to this second attachment housing and used to amplify the torque to be transmitted to the drill pipe.
- the drive source is available independently of the drive motor hydraulics of the excavator from the power head, which is vertically displaceable on the drilling mast and can be coupled with its connected connection adapter to a pipe adapter connected to the drill pipe.
- the invention With a generic hydraulic casing machine as an attachment to an excavator for a mobile rotary drilling rig, the invention thus opens up three variable possibilities for transmitting the drive power to the drill pipe. It thus achieves the task mentioned at the outset of creating such a piping machine in a simple and easily implementable manner from drilling point to drilling point, which in a previously unknown manner is capable of transmitting up to very high drive powers as torque to the drill pipe, with the possibility is given to gradually adjust the drive power depending on the prevailing local conditions. Further features of the invention can be found in the exemplary embodiment shown in the drawing and explained in more detail below. Show it
- Fig. 1 in side view the part essential to the invention
- Fig. 2 shows the essential parts of the machine of FIG. 1 in
- FIG. 3 shows a top view of the rotary drilling rig according to FIG. 1 below the line A-A with the sideways pivoted superstructure and drilling mast;
- Fig. 4 is the front view of FIG. 2 with impending Torque introduction via the rotary head connection adapter;
- FIG. 6 shows, partly in section, the piping mechanism according to the invention according to FIG. 5, but with a chain drive as a power transmission gear;
- Fig. 7 in side view of the essential part of the invention of a rotary drilling rig with the inventive rotary drilling machine and torque transmission
- Fig. 8 is a plan view of the rotary drilling rig of FIG. 7 from below the line B-B
- FIG. 9 shows a vertical section C-C through the base body of the piping machine according to FIG. 8 with a gear force transmission gear
- FIG. 10 shows a vertical section C-C through the base body of the piping machine according to FIG. 8 with a chain drive as a power transmission gear.
- Power head 13 on the drill pipe 17 can be brought into positive connection with the latter by means of the pipe adapter 29.
- the base body 1 of the piping machine is coupled to the undercarriage 10 by the articulations 9 in connection with the telescopic rods 23, 24.
- the base body 1 is hydraulically height-adjustable by means of a lifting foot cylinder 7 and is supported in a stationary manner on the ground by claws 8.
- a hydraulic-mechanical (wedge) clamping device 2 for the drill pipe 17 is arranged in the base body 1; it is rotatably supported by ball races 4.
- the clamping device is provided with hydraulic clamping cylinders 6 for actuating a clamping wedge arrangement.
- the tensioning device 2 On its circumference, the tensioning device 2 has a ring gear 3 or chain ring gear 25 with ring bearings. which is in engagement with a drive pinion 5 or via a drive chain 27 with the chain pinion 26.
- the drive or chain pinion 5 or 26 is mounted in an attachment housing 11 arranged on the side of the base body 1 and is in operative connection with a so-called Kelly box 12, which is used for the positive reception of the pivot pin 22 of the Kelly rod 19.
- a connection option for an add-on housing 11 is preferably provided on both sides of the basic body 1 of the piping machine; each attachment housing can be provided with a drive pinion 5 or a chain pinion 26. so that - seen from the carrier vehicle of the rotary drilling rig - the drill rod or the Kelly rod 19 can be brought into engagement either on the left or on the right on the base body 1.
- the connection that is not used in each case can be used for attaching a plastic lubricating tool 20 (FIGS. 2 to 4).
- both attachment housings 11 with a drive pinion 5
- a drive pinion 5 is operatively connected to a Kelly box 12 which controls the torque by engagement of the pivot pin 22 of the Kelly rod 19 receives while the other drive pinion 5 is coupled to a hydraulic gear motor 28 (Fig. 7 to 10) which is connected to the chassis hydraulic system of the carrier vehicle and supplies the hydraulic motor.
- the superstructure 16 with the drilling mast 15 is pivoted horizontally, as can be seen in FIG. 3, so that the Kelly rod 19 can be coupled into the Kelly box 12 of the add-on housing 11 by lowering.
- a counter adapter 18 on an attachment housing (11) equipped with a drive pinion 3 or a chain pinion 26 either with the Kelly box 12 or directly connected to the aforementioned pinions, which is connected to the connection adapter 14 can be coupled to the power turret 13. In this way, the torque of the rotary head 13 can be increased very considerably.

Only when the jacket friction of the drill pipe 17 becomes greater than the maximum torque of the rotary head 13 is the hydraulic-mechanical clamping device 2 clamped on the drill pipe 17, so that a torque can be transmitted directly to the jacket of the drill pipe 17.
- This clamp connection of the drill pipe 17 with the tensioning device 2 can be used in addition to the above-described torque introduction from the rotary head 13 via the connection adapter 14 and the pipe adapter 29 for an additional torque transmission in that, according to the further teaching of the invention, instead of the Kelly box 12, a hydraulic geared motor 28 is coupled to at least one of the drive or chain sprockets 3 or 26, so that its torque is increasingly transmitted to the drill pipe via the power transmission gear.
- the hydraulic geared motor 28 is connected to the chassis hydraulic unit and is supplied by this system.
- Kelly box 12 connected counter adapter 18 to one or both of the drive or chain sprockets 3 and 26, which are mounted in one or both of the add-on housings 11, to increase the drilling power.
- the transmission gear can also be formed by a chain drive consisting of the chain wheel 26, the chain ring 25 and the chain 27.
- a chain drive can also be realized in this way. that two chain rings 25 are arranged side by side on the same axis.
- the invention thus enables several possible combinations of the drives for the transmission of the torque and thus the drive power, and it is with the utilization of these possibilities, namely increased power of the power rotary head 13 with an additional motor and more direct
- the greater reaction forces from the stronger torque can be dissipated in the shortest possible way from the base body 1 via the linkage 9 by means of hydraulically or mechanically adjustable telescopic rods 23, 24 by introducing them into the undercarriage.
