Definitions

  • the invention relates to a drive for a carriage of an earth boring device with a rotary drive, an earth boring device with such a drive and a method for driving a carriage of an earth boring device with a rotary drive.
  • Earth drilling devices in particular horizontal drilling devices, are used in order to drill earth holes, for example for supply and disposal lines, into the ground in a trenchless manner, or to replace old lines that have already been laid in a trenchless manner.
  • a drill rod having drill rod sections is usually used, in which the drill rod sections can be connected to one another.
  • EP 0 886 034 B1 It is known to use a carriage reciprocable in a frame for advancing and/or pulling a drill string.
  • the carriage has a socket for a section of drill string, so that the section of drill string can be moved in the direction of a feed axis to create the earth bore in the socket.
  • the drive acting on the drill rod section can have a rotational and/or translational effect on the drill rod section in the receptacle.
  • an earth drilling device which comprises a movable carriage for vertically displacing a drill string.
  • an aerial work platform is known which has a compact rotary drive.
  • each of the hydraulic motors can have a planetary gear which has a feed pinion which engages with a toothed rack fixedly arranged in the frame and moves the carriage in the frame, in particular translationally. It is thus known for large and powerful earth drilling devices to use more than one motor, for example in order to be able to carry out the earth drilling in solid ground.
  • the use of several motors requires hydraulic connection lines to be provided for each of the motors and a rack attached to the frame for each of the motors. In addition, greater mechanical and hydraulic losses can result. Furthermore, the construction is relatively large.
  • the invention was therefore based on the object of creating an improved drive for a carriage of an earth drilling device with a rotary drive and a pinion driven by the rotary drive, which improves at least one of the aforementioned disadvantages, and in particular can also be of compact design for large and powerful earth drilling devices and have low efficiency losses can. Furthermore, an earth drilling device with such a drive should be created. A method for driving a carriage of an earth drilling device with a rotary drive should be created, which improves the aforementioned disadvantages, in particular cost-intensive construction, many components, large construction and/or high efficiency losses.
  • the core idea of the invention is the provision of a further pinion which is in engagement with the rack and which, like the first pinion which is in engagement with the rack, is driven indirectly or directly by the rotary drive.
  • a drive motor i.e. the rotary drive, which can have a gear
  • the power from a drive motor can be transmitted to a toothed rack via two pinions.
  • the use of two or more separate motors can be omitted.
  • the drive of a carriage of an earth drilling device has a rotary drive.
  • the rotary drive indirectly or directly drives a pinion that can be engaged with a rack.
  • the rotary drive is in engagement with a further pinion, which can be brought into engagement with the toothed rack.
  • One and the same rotary drive directly or indirectly drives the pinion, which can be engaged with the rack, and the other pinion. Both pinions are driven indirectly or directly by one and the same rotary drive.
  • An “earth drilling device” is understood to mean, in particular, any device which moves a drill rod containing drill rod sections in an existing or to be created channel in the ground in order to create or widen a bore, in particular a horizontal bore (HD), or to line or other long bodies in digging in the soil.
  • the earth drilling device can in particular be an HD device.
  • An “earth drilling device” according to the invention comprises a device that drives a drill rod, which works in a soil-displacing manner and introduces the drill rod in a rotary and/or translatory manner in the longitudinal axial direction of the drill rod into the ground.
  • HD horizontal drilling, horizontal drilling
  • earth channels including earth drilling, rock drilling or earth lines as well as underground or above-ground pipelines and water channels, the can be produced or drawn in by using an appropriate earth boring device.
  • the term “carriage” covers a body with a receptacle for a section of drill rods, it being possible for the section of drill rods to be driven in translation and/or rotation by means of the receptacle.
  • the carriage can be guided in the frame for a translatory movement along a track.
  • the carriage can rest on a support connected to the frame with support elements.
  • the support can be profiled and the uprising elements can be designed as rollers. Skids are also possible as
  • the carriage can be guided hanging and/or resting on the frame.
  • the carriage can thus be a machine element that can be moved in the frame along a path, in particular purely translationally.
  • the term “frame” includes a box-shaped or cuboid structure whose side walls and/or struts or rods can transmit pressure, tension and also bending.
  • the frame according to the invention preferably has a square elevation and can be arranged in a pit for creating the earth bore.
  • the frame can also be a frame that is above ground, ie above the ground, can be arranged.
  • the drive unit and carriage are preferably arranged in the frame.
  • the frame can be provided with horizontally extendable tensioning supports, via which the recoil forces can be introduced into the ground.
  • the pinion meshing with the rack can be arranged directly on the shaft of the rotary drive, so that the pinion meshing with the rack is driven directly by the rotary drive.
  • the other pinion, which meshes with the rack can be driven indirectly - namely by a third pinion which is interposed between the two pinions and meshes with the two pinions which are in engagement with the rack.
  • the rotary drive can also directly drive a pinion that is not in engagement with the toothed rack, in that the pinion is arranged directly on the shaft of the rotary drive.
  • the pinions which are in engagement with the toothed rack in turn mesh with the pinion of the rotary drive which is seated on the shaft.
  • the rotary drive has a drive pinion that meshes with the two pinions, so that the two pinions mesh with one and the same drive pinion and forced guidance of the two pinions by means of one drive pinion is possible.
  • the rotary drive can also be connected directly to one of the pinions that mesh with the rack, in that a pinion that meshes with the rack is placed on the shaft of the rotary drive and is thus driven directly by the rotary drive.
  • the rotary drive and the two pinions are preferably mounted on a flat structure which can be part of the carriage.
  • the flat structure can be, for example, a carrier surface of the carriage.
  • the two pinions rotate in the same direction.
  • the two pinions can thus simultaneously roll in the same direction of movement on the toothed rack and thus set the carriage in motion.
  • the two pinions are designed with helical teeth, so that in the case of helical gearwheel pairs between the drive pinion of the rotary drive and the pinion in engagement with the rack, two or more teeth are always in contact at the same time. Less hard impacts can occur when the helically toothed pinions mesh with one another—the drive pinion of the rotary drive can also have helical teeth—which leads to fewer vibration excitations. Tooth flow and pit carrying capacity can be made higher.
  • the pairing occurs between the helical pinion and the drive pinion of the rotary drive does not come into direct contact over its entire width, but the loaded tooth width increases slowly as the wheels under consideration continue to rotate until the tooth pair carries load over the entire width, and slowly decreases again when turning out of the contact zone.
  • the two pinions are arranged symmetrically to the rotary drive.
  • the two pinions are symmetrical to a drive pinion of the rotary drive with respect to a central axis through the drive pinion, which is perpendicular to the longitudinal axis of the toothed rack.
  • the rotary drive has a hydraulic motor, so that a cost-effective central drive unit can be created.
  • the rotary drive comprises a planetary gear, which is a compact gear in which the input and output shafts are aligned with one another.
  • the invention also provides an earth drilling device with a drive configured in accordance with the previous statements, the earth drilling device having a frame and a toothed rack fastened to the frame.
  • the drive moves together with the carriage in relation to the stationary rack on the frame.
  • the invention also provides a method for driving a carriage of an earth drilling device with a rotary drive, the rotary drive being in engagement with a pinion which engages in a toothed rack.
  • a further pinion is driven by means of the rotary drive, which is in engagement with the rack and a force is exerted on the rack by means of the further pinion.
  • the drive has a rotary drive 1 and a pinion 3 which is indirectly driven by the rotary drive 1 and which meshes with a toothed rack 5 which can be fixedly connected to a frame of an earth boring device.
  • the drive also has a further pinion 4 which is also in engagement with the toothed rack 5 .
  • the two pinions 3, 4 are thus in engagement with the rack 5 and the rotary drive 1 can be moved by rotating the pinions 3 and 4 relative to the rack 5 translationally in the extension of the rack 5 along this.
  • the pinions 3 and 4 are in engagement with a drive pinion 2 of the rotary drive 1.
  • the two pinions 3 and 4 are mounted on a flat structure 6 .
  • the two pinions 3 and 4 rotate in the same direction and have the same dimensions.
  • the two pinions 3 and 4 and the drive pinion 2 have helical gearing.
  • the rotary drive 1 is designed as a hydraulic motor and includes a planetary gear.
  • the 2 shows the engaged two pinions 3, 4 and the drive pinion 2 with the rack 5 in a view from below.
