Definitions
- the invention relates to a device for producing an earth hole of the type corresponding to the preamble of claim 1.
- Such a device is known from WO 97/34070.
- the striking tools are directly connected to the tool head in several ways, so that the impact energy is transmitted via the drive medium to the tools immersed in the borehole and from there directly to the bottom of the borehole, so that the connecting rod remains largely unaffected.
- the tool head is connected via the connecting linkage to a drive device, which is usually arranged outside the borehole, with a rotary drive, so that the tools arranged on the tool head work at ever new locations on the bottom of the borehole.
- the devices in question are primarily used in solid rock.
- the rock material loosened or abraded at the face or at the bottom of the borehole can be removed from the borehole within the hollow connecting rod in the manner of so-called "reverse circulation".
- the air lifting method can be used for this purpose, in which air is used as the flushing medium in the drill pipe above the tool head is blown in, so that the air rising in the connecting rod creates a pressure difference in the connecting rod between the borehole and the surface, which induces a flow velocity in the connecting rod with which the rock material is expelled through the connecting rod.
- the invention is therefore based on the object of providing a device which ensures satisfactory drilling progress in the most varied of rock formations.
- each of the tools comprises a scraper disc and means which cause the scraper disc to tumble during operation, each tool simultaneously exerts a striking hard rock loosening as well as a grazing, loosened hard rock and softer earth formations on the working face or bottom of the borehole out. Different rock formations can thus be efficiently solved and removed with the device according to the invention.
- pens or disc rolls can be used as removal means.
- An embodiment of the device according to the invention is particularly preferred in which at least one drive device is provided, by means of which the tool head can be set in rotation about the longitudinal axis of the bore.
- the drive device can be arranged outside the borehole and the torques can be transmitted via the connecting rod.
- the drive device for the tool head can be equipped such that the rotation takes place in a fixed sense of rotation, i.e. either clockwise or counterclockwise.
- the drive device in such a way that the rotation takes place alternating in the direction of rotation, for example by an angle of rotation between 90 ° and 270 °.
- This embodiment has the advantage that complex rotary leadthrough seals, such as those for the supply of fluid media to the tool head or grinding contact arrangements, such as would be necessary to introduce electrical currents - for example to drive the tools - can be dispensed with.
- the sealing or sliding contact arrangements can be replaced by simple, interference-resistant flexible cables.
- means are provided which move the scraping disc of each tool into a tool during operation of the device
- the means are, for example, hydraulic, pneumatic or electric rotary drives:
- the drilling efficiency is particularly high when the rotation frequency of the cutting disc of each tool is less than its wobble frequency.
- the ratio between the rotation frequency and the wobble frequency is preferably 1:30 to 1:60.
- each tool comprises a rotationally driven main shaft, which has a shaft journal, the axis of which forms an acute angle to the axis of the main shaft, and a head carrying the scraper disk, which is rotatably mounted about the axis of the shaft journal, and a peripheral region which runs on a counter circumference area.
- the scraper disc is set into drum motion by the main shaft at a frequency which corresponds to the rotational frequency of the main shaft.
- the device according to the invention in order to be able to optimally adapt the device according to the invention to different rock formations, it is particularly desirable to be able to vary the wobble to rotation ratio. In the particularly preferred embodiment of the device, this is made possible by the fact that the counter-peripheral region itself can be set in rotation. Depending on the direction of rotation of the counter circumference If the speed of the main shaft remains constant, the resulting speed of the scraper disc is increased or reduced.
- the counter circumferential area and the circumferential area running on it can be designed in any way that ensures running during operation. Because of the simplicity of manufacture and operational reliability, however, it is preferred if the peripheral region has external teeth and the counter peripheral region has internal teeth.
- the counter-circumferential area is preferably formed by a ring gear arranged concentrically to the main shaft axis, which can be set in rotation according to the particularly preferred embodiment of the invention.
- a preferred embodiment of the device according to the invention therefore provides that the counter-peripheral region can be set in rotation by means of a planetary gear which is in engagement with the main shaft. This embodiment has the advantage that no further drive motors are required.
- the separate drive is particularly preferably designed to be controllable or regulatable, as a result of which an adaptation of the Relationship between drill head speed and wobble frequency to the type of rock in question is possible.

- a tool head 40 which is provided for example for a hydraulic drive.
- the tools 41 driven by the hydraulic medium are via supports 44 connected to a mounting plate 42 which is attached to the lower end of the connecting rod 5.
- the digging disks 45 arranged on the tools 41 act downward on the base 10 of the hole 9 and break up the rock there. The respective point of attack moves in the circumferential direction due to the rotation of the tool head.
- the number and arrangement of the tools 41 can be adapted to the diameter of the hole 9 and the material to be removed.
- the tools 41 are held and guided at their lower ends on a circular disk-shaped guide plate 46 of a diameter corresponding to the hole diameter.
- FIG. 5 shows a tool 41 in a detailed representation. It includes a head 46 which carries the scraper 45.
- the scraper 45 is attached to the head 46 with a plurality of cheese head screws 47, only one of which is shown in the drawing.
- the scraper disc 45 is provided with a central cutting edge 48.
- the scraper disc 45 has three arms 50 which extend radially outward and which - as can be seen in the arm shown on the left in the drawing - are equipped with a plurality of chisels 51.
- the head 46 is rotatably mounted on a shaft journal 54 of a main shaft 55 by means of tapered roller bearings 52, 53.
- the essentially cylindrical outer circumferential surface has a shaft journal 54 molded onto the main shaft 55 in such a way that its axis B forms an acute angle w of approximately 3 ° with the axis of rotation AA.
- the main shaft 55 is in turn supported by tapered roller bearings 56, 57 in a machine housing 58 about the axis of rotation AA and is rotatably driven by a hydraulic motor 59 flanged on the end face.
- the part of the head 46 facing away from the scraper disk 45 is designed as a gearwheel arranged concentrically to the axis B of the shaft journal 54, hereinafter called the wobble wheel 60, and thus as a circumferential region 61 which, when the main shaft 55 rotates, runs in an internal toothing 63 acting as a counter circumferential region 62.
- the internal toothing 63 is formed on a ring gear 64 which is arranged concentrically to the main shaft axis and is rotatably mounted relative to the latter.
- the ring gear has a further internal toothing 65, which is part of a planetary gear designated as a whole by 71.
- the toothing of the parts of smaller diameter 67 from the planetary gearwheels 66 engage in the internal toothing 65.
- the parts 68 of larger diameter of the planetary gearwheels 66 engage with their toothing in an external toothing 69 provided on the main shaft 55 and in an internal toothing 70 provided in the machine housing 58, so that the planetary gearwheels orbit the rotational axis AA in the same direction of rotation while the main shaft 55 is being driven ,
- the ring gear 64 is rotated in opposite directions to the scraping wheel 45, the rotation of which is moved by the wobble wheel 60 running on the internal toothing 63. It is understood that by selecting the ratios in the planetary gear 71, the rotational speed of the ring gear 64 relative to the main shaft 55 and thus the result Ratio of wobble frequency to rotation frequency of the scraper 45 can be specified.
- FIG. 6 shows a second embodiment of a drive device. Parts that correspond functionally to one another are provided with reference numerals increased by 100. The basic structure largely corresponds to that of FIG. 1. The description there also applies to the present embodiment.
- the drive assembly of the device is fastened to a support device 102 which is supported on a work platform designated overall by 101.
- a schematically shown rotary drive head 104 engages on a connecting rod 105 which extends through the work platform 101 into the earth hole to be produced and up to the tool.
- the connecting rod 105 can be driven by means of the rotary drive head 104 in a conventional manner known from the prior art.
- a first connection head designated 110
- a flushing liquid usually air
- a second connection head is arranged below the first connection head 110.
- the support device 102 can be tilted about a horizontal axis A by means of a swivel drive 106, so that earth holes can also be drilled deviating from the vertical.
- the second connection head 120 as a whole can connect with the connecting rod 105 rotate, and only the first rotary connection head 110 is fixedly mounted.
- the rotary drive head 104 is designed such that it rotates the connecting rod 105 with the second connection head 120 for the drive medium of the hammers in the tool in an oscillating manner by a predetermined angle about the axis of rotation of the rod 105.
- This swept angle is generally below 360 ° and is selected depending on the number and position of the tools 41 lying on the same radius. With only one tool 41 per radius, 360 ° is required, with two tools per radius offset by 180 °, a back and forth rotation of 180 ° is sufficient. However, it is also within the scope of the invention to turn the tool head back and forth by a limited but larger angle than 360 °.
- the drive medium is introduced into the second feed 122 of the connecting rod 105 by means of a flexible hose 115.
- the hose 115 is mounted between the second feed line 123 and the second feed 122.
- the length of the hose 115 is chosen so that the hose 115 can follow the rotation of the connecting rod 105 without hindering it.
- the supply line 223 for the working medium, the supply line 213 for the compressed air and the outlet pipe 221 are flexible hoses educated.
- the two feed pipes 213 and 223 are connected below the rotary drive 204 at points 213 ', 223' to the line 212, 222 running on the connecting rod 205 via flange arrangements (not shown in detail) which the compressed air of the inlet opening (43 in Fig. 2) or the working medium with the tool head (40 in Fig. 2) is supplied.
- the advantage of this embodiment is that the rotary drive head 204, which, however, only causes an oscillating movement in this case, only has to include a rotary bearing for the connecting rod 205, but there is no need for rotary unions and rotary seals.
- a rotary drive 4 ' which acts externally on the connecting rod 205 and whose mode of operation and function also otherwise corresponds to that of the rotary drive 4', however, only causes a reciprocating movement of the linkage.
- FIG. 8 Another embodiment of the device according to the invention is shown in FIG. 8. Parts which correspond to one another functionally are provided with reference numerals increased by 300 with respect to the embodiments in FIG. 1. In this case, an upper bearing in the context of the rotary drive 204 in FIG. 7 or a rotary connection head completely waived.
- a drive unit 304 serves for the oscillation drive, the function of which corresponds to that shown in FIG. 9 and to be described further below.
- connection of the hose lines 313, 323 to the inlets 312, 322 and the hose line 321 to the inside of the connecting rod 305 takes place with the aid of a flange head 360 arranged at the upper end of the upper segment of the connecting carrier, which is designed such that connections provided thereon for the hose lines 313, 323, 321 communicate with the lines 312, 322 or the interior of the connecting rod.
- the drive unit 304 is mounted on the support unit 302 via length-adjustable force generators 302 ', so that the drive force 304 can also be introduced into the connecting linkage by lowering the drive unit 304. Once the drive unit 304 has reached its lower position, a further advance can be effected by "follow-up", in which it is released and fixed again after it has been moved to a higher position with the aid of the force generators and the process begins again.
- This device does not require a support unit, the length of which corresponds at least to that of a segment of the connecting rod 5, this embodiment is distinguished by a particularly low overall height.
- FIG. 10 shows a further embodiment of one of the tools 41.
- the support device designed as a double arm 72 carries out only a wobble movement for the removal means, but no rotational movement.
- the mechanical structure of this tool is therefore considerably simplified compared to that according to FIG. 5, since there is no counter-peripheral surface on which the peripheral surface runs to generate the rotation, and thus the entire transmission can be dispensed with.
- the central drive can contain a gearbox with drive shafts for each tool so that wobble frequencies can also be varied.
- the tools according to FIG. 10 are arranged in the tool head in such a way that their double arms 72 extend perpendicular to the tangent of the circles or circular sections which they sweep over due to the rotation of the tool head. They are also - as shown schematically in Fig. 11 - laterally offset, so that individual cutting tools 451 work in different tracks.
