Definitions

  • the invention relates to a drilling device, in particular for direction-guided horizontal drilling.
  • a drilling device is also referred to as a horizontal drilling device.
  • the drilling device has a drilling ramp and at least one anchoring means for anchoring the drilling device in the ground, it being possible for the anchoring means to be introduced into the ground along an anchoring axis.
  • a drilling head arranged at the end of a rod assembly remote from the drive unit of the drilling device is introduced into the ground and moved through the ground to a desired depth and along a desired course.
  • Such a horizontal drilling method is also referred to as a horizontal directional drilling (HDD) method.
  • HDD horizontal directional drilling
  • Horizontal drilling devices are known in which a hollow rod assembly composed of several rod sections is introduced into the ground at a starting point with the aid of the horizontal drilling device.
  • the horizontal drilling device can introduce flushing fluid into the hollow rods at high pressure, which then emerges at the drill head at high pressure.
  • a borehole is drilled into the ground by the high pressure of the flushing liquid and the hard metal teeth of the drill head.
  • Another drilling device is from the document DE 10 2017 113 247 A1 famous.
  • U.S. 6,497,296 B1 a drilling device is known which comprises two anchoring means which can be introduced into the ground. The anchoring means are connected via a connecting element which can be pivoted about a tilting axis.
  • horizontal drilling rigs are equipped with anchoring systems.
  • a base plate is mounted on the front end of the drilling device facing the borehole to be produced. So that these are independent of the angles of attack of the drilling ramp
  • anchoring means Rests on the ground, such base plates are pivotally connected to the drilling ramp via a hinge arrangement.
  • anchoring means usually comprise a screw anchor which can be screwed into the ground via a hydraulic motor and a hydraulic cylinder.
  • Other anchoring means include anchor plates or anchor rods driven into the ground.
  • anchoring means are fastened to the two front corners of a base plate, ie to the area of the base plate facing the borehole to be produced.
  • Horizontal drilling devices are also known in which the bottom plate is provided with a rim so that it serves as a collecting pan for flushing liquid.
  • a disadvantage of the known solutions is that there is a distance of 0.5 m or more between the anchoring means and the hinge with which the base plate is articulated on the drilling ramp. This results in a lever arm through which, particularly in the case of high drilling or pulling forces of the horizontal drilling device, a relatively large tilting moment is created, as a result of which the base plate is lifted sharply from the ground in the front area towards the borehole or in the rear area towards the drilling ramp, thereby reducing the stabilizing function of the base plate no longer takes place to the required extent to stabilize the horizontal drilling device.
  • the object of the invention is to specify a drilling device that achieves a high level of stability during drilling operations.
  • a stable anchoring of the drilling ramp in the ground is achieved by providing a connecting element that protrudes laterally from the drilling ramp and to which the anchoring means for anchoring the drilling device in the ground is connected.
  • this avoids connections of the anchoring means via structural elements with a long lever, such as hinged floor panels.
  • a reduction in the number of joints between the drilling ramp and the anchoring means results in a more stable anchoring of the drilling ramp in the ground.
  • the connection to the ground cannot loosen due to play in the joints of the joint chain, nor do several joints have to be designed in such a way that they must be able to transmit the forces occurring through the corresponding lever arms and the anchoring of the anchoring means in the ground.
  • the device has at least two connecting elements protruding laterally from the drilling ramp and at least two anchoring elements which are each designed and arranged in such a way that the anchoring elements can be pivoted about a longitudinal axis of the respective connecting element or can be displaced along the respective longitudinal axis of the connecting element. It is particularly advantageous if the anchoring elements can be pivoted independently of one another about a longitudinal axis of the respective connecting element. This achieves secure and flexible positioning of the anchoring means and simple anchoring of the drilling ramp in the ground.
  • the anchoring means or means is or are arranged so as to be pivotable about a longitudinal axis of the respective connecting element.
  • the anchoring means can be locked in at least one pivoting position, preferably in at least three pivoting positions.
  • the anchoring means can be introduced into the ground at a desired angle even with different angular positions of the drilling ramp.
  • this advantageously makes it possible for the entry angle of the anchoring means to be selectable from a number of possible entry angles.
  • the anchoring means or means is or are displaceably arranged along the longitudinal axis of the respective connecting element.
  • the anchoring means can be locked at least at a lateral distance from the drilling ramp.
  • the anchoring means or means are preferably arranged such that they can be displaced along the longitudinal axis of the respective connecting element by a distance in the range between 10 cm and 30 cm.
  • the anchoring means can be brought into a desired lateral position, so that the anchoring means can be introduced into the ground at a desired adjustable lateral position.
  • the lateral position can be selected in such a way that areas in the ground into which the anchoring means cannot be introduced are avoided.
  • the longitudinal axis of the connecting element is arranged orthogonally to the longitudinal axis of the drilling ramp, in particular skew orthogonally to, preferably below, the longitudinal axis of the drilling ramp.
  • the longitudinal axis of the drilling ramp can run parallel to or along the direction of advance of a drill rod that can be driven by the device. This enables a simple and stable structural design for connecting the anchoring means to the drilling ramp.
  • the connecting element has a cylindrical lateral surface which is partially enclosed by a connecting area of the anchoring means, the connecting area having an opening with a round cross-section complementary to the cylindrical lateral surface of the connecting element.
  • the longitudinal axis of the respective anchoring means and the longitudinal axis of the respective connecting element are orthogonal, in particular skewed orthogonal, with the longitudinal axis of the anchoring means having a distance in the range between 0 cm and 30 cm, preferably in the range between 5 cm and 20 cm to the longitudinal axis of the anchoring means.
  • the anchoring means may comprise a helical or auger-like anchoring element.
  • anchoring rods can also serve as anchoring elements of the anchoring means.
  • the device does not include a base plate for supporting the drilling ramp or if the anchoring means or means is/are not arranged on the base plate. This avoids a link chain between the anchoring means and the drilling ramp, so that the structural effort required to provide the anchoring means is lower than with known horizontal drilling devices.
  • connecting element and/or the connecting elements is/are rigidly connected to the drilling ramp.
  • the connecting element(s) can preferably be formed in one piece with the drilling ramp, in particular screwed firmly to the drilling ramp or welded firmly to the drilling ramp. This allows for a simple and very stable construction of the drilling device.
  • the device comprises at least one rinsing liquid collecting trough, which is independent of a base plate, for catching and preferably for draining off rinsing liquid escaping in the area of the drilling ramp.
  • This makes it possible to collect at least part of the flushing liquid that can escape from the interior of the rod sections when the rod is replaced when the rod is retracted or when the rod is advanced and, if necessary, reuse it. This saves flushing liquid and contamination of the drilling device is avoided.
  • the device has a feed drive, in particular a drive carriage, for feeding a drill rod composed of a plurality of rod sections and which can be coupled at one end to the feed drive Has.
  • the rod sections are preferably hollow, so that flushing liquid can escape from the drilling device or the feed drive to a drilling tool, which is connected to the other end of the drill rod remote from the drilling device, in order to flush out the soil and cool the drill head during the drilling process and discharging spoil from the created borehole.
  • the flushing liquid collecting pan is arranged below a separation point between a first and a second rod section of the drill rod.
  • it can have a vertical distance in the range from 5 cm to 30 cm, in particular in the range between 10 cm and 20 cm, from the drill rod.
  • flushing liquid trough is firmly connected to the drilling ramp.
  • the flushing liquid trough can be integrated into the drilling ramp.
  • the or a further flushing liquid trough can be arranged between the drilling ramp and a chassis for moving the drilling ramp.
  • the rinsing liquid collecting trough or at least one of the rinsing liquid collecting troughs has a length in the feed direction in the range between 0.5 times to 1.5 times, in particular 0.5 times to 0.75 times the length of a rod section and has a width transverse to the feed direction in the range of 20 cm to 50 cm.
  • the device has at least two liquid collecting troughs for collecting rinsing liquid, which are arranged at different heights are, wherein the arranged in a higher position liquid collecting pan has an overflow through which collected washing liquid is conducted into the second washing liquid collecting pan.
  • one or each of the rinsing liquid collection pans has one or more outlets for the targeted discharge of the rinsing liquid collected or at least one of the rinsing liquid collection troughs has a pump for conveying the collected rinsing liquid out of the rinsing liquid collection trough.
  • the rinsing liquid can be easily conducted or conveyed away from the drilling device, so that contamination in the area of the drilling ramp is avoided and at least part of the rinsing liquid can be reused if necessary.
