Definitions

  • the invention relates to a drill, in particular for creating holes in the ground, according to the preamble of claim 1.
  • Such a drill comprises a carrier vehicle with a hydraulic supply, a mast, a carriage which is movable along the mast, and a hydraulic cylinder for moving the carriage, which comprises a cylinder housing in which a piston is slidably mounted with a piston rod.
  • hydraulic cylinders In hydraulic cylinders, it is customary to arrange the cylinder housing on the fixed side and the piston rod on the movable side, since the hydraulic connection of a hydraulic cylinder is located on the cylinder housing and should not be moved as far as possible. This ensures a simple and maintenance-friendly connection of the hydraulic cylinder to a hydraulic supply.
  • a drill with a hydraulic cylinder for moving a carriage on a mast the cylinder housing is attached to the carriage, goes out of the EP 2 339 108 A1 out.
  • the piston rod of the hydraulic cylinder is mounted on a movable element on the mast.
  • EP 0 525 186 A1 describes a cultivator with an extendable mast on which a plurality of hydraulically actuated actuators are provided, which are connected via flexible hydraulic hoses to hydraulic lines on the carrier vehicle.
  • WO 2011/057493 A1 discloses a hydraulic system for a drilling rig, in which a hydraulic cylinder for moving a carriage along a mast is articulated with its cylinder housing on the mast and with its piston rod on the carriage.
  • the invention has for its object to provide a drill with a structurally simple carriage drive, which is particularly economical to operate.
  • the piston rod is attached to the mast and the cylinder housing on the carriage, that the carriage is connected to the hydraulic supply and has at least one hydraulic connection and that the hydraulic cylinder is connected via the hydraulic connection on the carriage with the hydraulic supply.
  • a first basic idea of the invention is to install the hydraulic cylinder so that the cylinder housing is mounted on the carriage and thus moves together with the carriage relative to the mast. Since the hydraulic cylinder is usually located above the carriage with an upright mast to push down the carriage in the drilling operation, the center of gravity of the drill is displaced downwards by the cylinder housing arranged below. Because the cylinder housing usually has a greater weight than the piston mounted therein with the piston rod. The inventive installation direction of the hydraulic cylinder thus leads to improved stability of the drill.
  • a second basic idea of the invention can be seen in connecting the hydraulic cylinder via the carriage to the central hydraulic supply of the drilling device, which is usually arranged on the carrier vehicle.
  • the supply of the hydraulic cylinder with hydraulic fluid, in particular hydraulic oil has the advantage that no relative movements take place between the cylinder housing and the slide.
  • For a simple wiring between the carriage and one or possibly more inlet ports on the cylinder housing is possible.
  • At least one hydraulic connection is provided on the carriage, via which hydraulic fluid can be supplied to the hydraulic cylinder.
  • the hydraulic connection is in turn connected to a central hydraulic supply.
  • the hydraulic connection which may for example have a coupling device for coupling a hydraulic line, is fixedly mounted on the carriage and moves together with it.
  • the hydraulic connection can be arranged on a holding device fastened to the carriage, such as a holding plate.
  • At least one distribution device for distributing hydraulic fluid is arranged.
  • the distribution device is connected via a central supply line and a central return line to the hydraulic supply.
  • the hydraulic fluid provided by the central hydraulic supply can be distributed to several consumers.
  • return hydraulic fluid can be collected at the distributor and fed to the central return line.
  • the central distribution device thus makes it possible to supply several consumers in the region of the carriage with hydraulic fluid.
  • the distribution device has one or more hydraulic connections.
  • the drive motor on the carriage may for example be a hydraulic rotary drive for a drill pipe or a hydraulic vibrator.
  • both the hydraulic cylinder and the drive motor on the slide can be supplied with hydraulic fluid from the central hydraulic supply via the distributor device.
  • the distributor for distributing hydraulic fluid to the hydraulic cylinder and one or more other consumers are fixedly mounted on the carriage and move therewith.
  • the hydraulic connection for the hydraulic cylinder and the at least one further hydraulic connection are arranged on the distribution device. By distributing hydraulic fluid is thus distributed to several hydraulic connections.
  • At least one distribution device is arranged on the mast.
  • the distribution device on the mast allows easy cable routing between the central hydraulic supply and the distribution device, since the position of the distribution device on the mast is independent of a carriage movement along the mast.
  • the distribution device is fixedly mounted on the mast.
  • the hydraulic cylinder for moving the carriage can be a single-acting cylinder, in which the cylinder housing is moved by supplying hydraulic fluid with respect to the piston rod and moves the carriage in the direction of the borehole to be created, preferably downwards.
  • the hydraulic cylinder is a double-acting cylinder with two cylinder chambers and that two hydraulic connections are provided on the carriage, wherein a first cylinder space of the hydraulic cylinder with a first hydraulic connection and a second cylinder space with a second hydraulic connection is line connected.
  • the first hydraulic connection can be connected to a lower cylinder space of the hydraulic cylinder and the second hydraulic connection to an upper cylinder space of the hydraulic cylinder.
  • An advantageous supply of the hydraulic cylinder with hydraulic fluid is achieved in that at least one hydraulic line is arranged between the hydraulic connection and the hydraulic cylinder, which extends from the hydraulic connection upwards along the mast.
  • the supply of hydraulic cylinder with hydraulic fluid is thus carried on largely direct way from the carriage to the corresponding connection piece on the cylinder housing.
  • the entire line between the hydraulic connection on the carriage and connecting piece on the hydraulic cylinder is movable relative to the mast. A comparatively complex supply via the mast can thus be dispensed with.
  • a particularly robust carriage drive can be achieved by providing a fixed pipeline between the hydraulic connection on the carriage and the hydraulic cylinder.
  • a fixed pipeline is understood in particular to mean a largely dimensionally stable or rigid conduit.
  • the line can be formed for example of metal, but also of a suitably solid plastic.
  • the line between the hydraulic connection and the connecting piece is attached to the cylinder housing with at least one fastening device on the cylinder housing.
  • An advantageous connection of the hydraulic cylinder to the central hydraulic supply can be achieved in that at least one central supply line is arranged between the hydraulic connection and the hydraulic supply, which is fastened to a holder on the mast. Since the mast itself, during drilling operations, usually moves only slightly with respect to the carrier vehicle, in particular the superstructure, a secure carrier can be secured by the holder fastened to the mast Cable laying done. Thus, a flexible conduit is required substantially only in a portion between the bracket on the mast and provided on the slide hydraulic connection.
  • the flexible line section between the holder and the hydraulic connection can be kept particularly short, that the holder is arranged centrally with respect to the cylinder housing of the hydraulic cylinder on the mast. Between mast and carrier vehicle can also run a flexible line section.
  • the holder is arranged in particular at approximately half the travel distance of the carriage along the mast.
  • Fig. 1 shows a drilling device 10 according to the invention with a mast 16, which is in a folded, approximately horizontal transport position.
  • the drilling apparatus 10 comprises a carrier vehicle 12 with an undercarriage 13 and an uppercarriage 14, which is mounted rotatably on the undercarriage 13.
  • the undercarriage 13 may have a chassis, in particular a crawler track.
  • the mast 16 is pivotally mounted on the carrier vehicle 12, in particular on the superstructure 14, via a pivot joint 20 and can be pivoted between an approximately horizontal transport position and an approximately vertical operating position.
  • one or more erection cylinders 26 are provided, which on the one hand on the mast 16 and on the other a corresponding pivot point on the carrier vehicle 12 are attached.
  • the erection cylinder 26 may also be referred to as a neck cylinder.
  • a carriage 22 is mounted longitudinally displaceably along a guide device 18.
  • the guide device 18 may in particular comprise a guide rail, which is in engagement with guide shoes of the carriage 22.
  • a carriage drive 28 which comprises a hydraulic cylinder 30 with a cylinder housing 32 and a piston 34 displaceably mounted therein.
  • the piston 34 is fixed to a piston rod 36 whose longitudinal axis is coaxial with the longitudinal axis of the cylinder housing 32.
  • the piston rod 34 is attached to an upper pivot point 40 on the mast 16.
  • the articulation point 40 comprises a pivot joint with a pivot pin, which is mounted on a bearing plate 42 of the mast 16.
  • the cylinder housing 32 is fastened to the carriage 22 at a lower articulation point 38.
  • the pivot point 38 also includes a pivot joint with a pivot pin.
  • a central hydraulic supply 80 For actuating the hydraulic cylinder 30, this is connected to a central hydraulic supply 80.
  • the connection to the central hydraulic supply 80 takes place via a hydraulic connection 50 which is fixedly arranged on the carriage 22 and can be moved relative thereto with respect to the mast 22.
  • a bracket 58 or retaining plate is attached to the carriage 22 laterally, which carries the hydraulic connection 50.
  • the hydraulic cylinder 30 comprises a first, lower connecting piece 44 which is connected to the hydraulic connection 50 via a first hydraulic line 62. Furthermore, the hydraulic cylinder 30 comprises a second, upper connecting piece 46, which is connected via a second hydraulic line 64 to a second hydraulic connection 52 on the slide 22.
  • the first connection piece 44 is with a first cylinder space of the hydraulic cylinder 30 and the second connecting piece 46 with a second cylinder chamber of the hydraulic cylinder 30 conductively connected.
  • At least one further hydraulic connection 54 for a hydraulic motor for example a rotary drive for a drill pipe, is located on the carriage 22, in particular on the holding device 58. Both the hydraulic connections 50, 52 for the hydraulic cylinder 30 and the further hydraulic connection 54 are connected to the central hydraulic supply 80.
  • the hydraulic connections 50, 52, 54 are arranged on a distributor device 60, which distributes hydraulic fluid from the central hydraulic supply 80 to the hydraulic connections 50, 52, 54. Furthermore, a return connection 56 for returning hydraulic fluid is located on the distributor 60.
  • the distribution device 60 is attached to the carriage 22 and may also include the holding device 58.
  • a bracket 70 is attached to the mast 16, to which a central supply line 82 and a central return line 84 are connected.
  • the bracket 70 may include another distributor 72 as shown in FIGS Figures 2 and 3 shown schematically.
  • a distributor device 72 for distributing hydraulic fluid between the upper and the lower cylinder chamber of the hydraulic cylinder 30 is provided on the mast 16.
  • the corresponding distribution can also take place at the distributor device 60 on the carriage 22.
  • the hydraulic cylinder 30 is thus connected via a fixedly arranged on the carriage 22 first bracket 58 and a fixedly arranged on the mast 16 second support means 70 to the central hydraulic supply 80.
  • Both holders 58, 70 may also be designed as distributing means 60 and 72, respectively.
  • one or more flexible hose sections 74 are provided for supplying and / or returning hydraulic fluid.
  • the flexible hose sections include a portion of a hydraulic line to the lower cylinder space of the hydraulic cylinder 30, a portion of a hydraulic line to the upper cylinder space of the hydraulic cylinder 30 and a portion of a return line.
  • Farther Line sections may be provided to the at least one further hydraulic port 54 on the distributor 60, which are not shown in the figures.
  • the flexible hose portion 74 may be part of the central supply line 82 and / or the central return line 84.
  • a drill with a structurally simple carriage drive is provided with the drill according to the invention, which also allows an economic erection and lowering of the mast with respect to the carrier vehicle.
