Definitions

  • the invention relates to a Kelly rod arrangement for a drilling device, in particular an earth drilling device, with a tubular outer kelly rod which is designed to rest on a drill drive and to absorb a drilling torque of the drill drive, and with an inner kelly rod which is slidably mounted within the outer kelly rod and on its upper one
  • the end has a rope suspension, the drilling torque being transferable between the outer kelly rod and the inner kelly rod, according to the preamble of claim 1.
  • the invention relates to a method for soil cultivation, in which a Kelly bar arrangement is set in a rotary movement by means of a drill drive, a soil cultivation tool which processes a soil is attached to an inner kelly bar of the Kelly bar arrangement, according to the preamble of claim 12.
  • Kelly bar arrangements for a drilling rig have long been known in civil engineering.
  • Kelly bar arrangements of this type are telescopic and have an outer outer kelly bar which is in rotating connection with a drill drive of the drilling device.
  • an inner kelly rod and, if necessary, further intermediate kelly rods are arranged, which are axially displaceable in the outer kelly rod and mounted in relation to one another.
  • the inner kelly bar has a rope suspension at its upper end, so that the inner kelly bar and also the entire Kelly bar arrangement can be held on the rope and moved vertically.
  • axially extending stop strips are provided on the outer and inner sides of the individual Kelly bar elements, which allow both an axial movement and a torque transmission in the circumferential direction.
  • Such a Kelly bar arrangement enables an efficient rope suspension of a soil cultivation tool with the simultaneous possibility of torque transmission.
  • the telescopic ability of the individual Kelly bar elements to one another enables machining depths to be reached which are greater than the height of the mast of a drilling device.
  • Kelly bar arrangements of this type are used for working with simple mechanical soil cultivation tools, such as a drilling bucket or an auger.
  • the use of a Kelly bar arrangement becomes problematic when a medium, for example a rinsing liquid or a pressure fluid, is to be supplied from the outside.
  • the invention has for its object to provide a Kelly-rod assembly and a method for working the soil with a Kelly-rod assembly, which are particularly versatile.
  • the Kelly bar arrangement according to the invention is characterized in that at least one line is arranged along the inner kelly rod, that a rotary feedthrough with a first end section and a second end section is arranged at an upper end region of the inner kelly rod, the first connection section being connected to the rotatably drivable Kelly rod and forms a line connection to the at least one line of the inner kelly rod and the second connection section is connected to a supply line which is fixed relative to the rotatably drivable inner kelly rod, and that a rotating device for actively rotating the two connection sections relative to one another is arranged on the rotary leadthrough.
  • a first aspect of the invention is to provide a rotary leadthrough on the inner kelly rod.
  • a rotary leadthrough is an element that enables a line connection between a rotating part and a part that is fixed relative to it. This rotary leadthrough is arranged at an upper end area of the inner kelly rod. Furthermore, at least one line is provided along the inner kelly bar, which leads from the upper end area to a lower area of the kelly bar.
  • a rotary device for actively rotating the two connection sections relative to one another is arranged on the rotary leadthrough.
  • the invention is based on the knowledge that the upper end of the inner kelly rod can be moved as far as a lower end region of the outer kelly rod when the Kelly rod arrangement is telescoped out. A necessary reliable mechanical support of the rotary leadthrough with respect to a part that is fixed relative to the rotating Kelly rod arrangement is practically impossible. There is a risk of the supply line rotating with the rotating inner kelly rod.
  • a rotary device is provided for actively rotating the two connection sections relative to one another. In this way, undesired wrapping of the feed line around the rope can be counteracted in a targeted manner.
  • a Kelly bar arrangement with the advantageous rope suspension and telescopic ability with simultaneous torque transmission can also be used for soil cultivation tools in which the supply of a fluid, energy or data via a supply line from the outside is necessary or desired.
  • the rotary leadthrough can be arranged at any point on the upper end region of the inner kelly rod. According to a variant embodiment of the invention, it is particularly advantageous that the rotary leadthrough is arranged on the inner kelly rod below the cable suspension.
  • the rotary leadthrough can be designed in the shape of a ring, the cable suspension thus being able to be arranged in a central area of the rotary leadthrough.
  • the rotating device has at least one drive motor for actively rotating the second connection section relative to the first connection section.
  • further drive motors can also be provided.
  • the drive motor is arranged on the second connection section which is above the first connection section. There is thus good accessibility to the drive motor.
  • energy can be supplied to the drive motor in parallel or with the supply line.
  • the drive motor is an electric motor or a hydraulic motor.
  • the drive motor can be made very compact overall, since only relatively low torques must be applied for the necessary compensation of the rotary movement between the two connection sections.
  • a compressed air motor can also be provided.
  • a further advantageous embodiment of the invention consists in that the cable suspension has a cable swivel.
  • a cable vortex in the sense of the invention is a swivel joint which enables a lower linkage of the cable vortex to the inner kelly rod to be rotated relative to an upper linkage of the cable vortex to the suspension cable.
  • the line of the inner kelly rod can be used as a hollow line, for example a hose or a pipe, or as a cable for conducting electrical current or be formed by data.
  • an axial cavity of the inner kelly rod is provided as a line, which is designed for the passage of a fluid.
  • the fluid can in particular be a rinsing liquid or a concrete suspension.
  • a connection area can be provided with which a line connection to a soil working tool, in particular a drilling tool, attached to the lower end of the inner kelly rod can be provided.
  • a cable is provided as a line on the inner kelly rod, which cable is designed to conduct electricity and / or data.
  • the cable can be guided as an additional line along the axial cavity of the inner kelly rod.
  • the rotary leadthrough is designed alone or in addition with corresponding contact rings on the two connection sections, which ensure a frictional contact for power or data transmission during a rotary movement.
  • the invention further comprises a drilling device, in particular an earth drilling device, with a drill drive, the above-described Kelly bar arrangement according to the invention being provided.
  • the drill drive is preferably designed like a ring with a passage through which the outer kelly bar of the kelly bar arrangement is passed.
  • the annular rotary drive has an annular drive wheel which is provided with drive projections on its inside. For torque transmission, these interact in a known manner with axial drive strips on the outside of the outer kelly rod.
  • a control is provided for the rotating device and that a rotation sensor is provided for determining a speed and / or a direction of rotation of at least the inner kelly rod is in signal connection with the controller.
  • the rotary device is driven in a controlled manner by the control device, so that the second connection section of the rotary leadthrough is driven and synchronized counter to a rotary movement of the inner kelly rod.
  • the rotational movement of the inner kelly rod is precisely compensated so that the opposite rotational movement by the rotating device achieves a desired standstill of the second connection section with the supply line, which in principle can also be a fluid line and / or a cable.
  • the method according to the invention for soil cultivation which can be carried out in particular with the drilling device described above, is characterized in that a rotating device is provided for actively rotating the second connection section relative to the first connection section, the second connection section being operated in the opposite direction to a rotary movement of the inner kelly rod.
  • a particularly precise coordination of the rotary movement can be achieved in that the rotary device is operated as a function of the speed of the inner kelly rod or of the drill drive.
  • a speed setting of the drill drive can be used directly as a default for the rotary device.
  • the rotational speed of the inner kelly rod or the drill drive can be recorded by a rotary transducer and used to control the rotary device.
  • a drill 10 according to Fig. 1 comprises a crawler undercarriage 12, on which an upper carriage 14 is rotatably mounted.
  • a substantially vertical mast 20 is pivotably articulated to the superstructure 14 and can be adjusted with regard to mast inclination by means of an adjusting arrangement 18 with hydraulic cylinders.
  • a mast head 22 is attached, over which a support cable 30 is guided to a winch 16 on the superstructure 14.
  • a Kelly bar arrangement 40 according to the invention is attached to the support cable 30 by means of a cable suspension 60.
  • the Kelly bar arrangement 40 is guided in a basically known manner through an annular drill drive 24, which is also referred to as a power rotary head and is mounted on a slide 25 so that it can be moved vertically along a guide on a front side of the mast 20.
  • a soil cultivation tool 26 is attached, which in the illustrated embodiment is designed as a drilling bucket with lower cutting teeth.
  • the Kelly bar arrangement 40 can be displaced in a generally known manner relative to the drill drive 24 in the vertical direction via the winch 16 and the carrying cable 30.
  • the Kelly bar arrangement 40 enables a soil cultivation tool 26 to be suspended from a rope with the simultaneous possibility of transmitting a torque from the drill drive 24 to the soil cultivation tool 26.
  • the structure of the Kelly bar arrangement 40 according to the invention is explained in more detail in connection with FIGS Figures 2 to 4 explained.
  • the representation of Fig. 3 is rotated by 90 ° to the representations to the Figures 2 and 4th .
  • the Kelly rod arrangement 40 has an outer kelly rod 42 with outer drive strips 46, an inner kelly rod 50 with outer drive strips 53 and an intermediate kelly rod 48 with outer drive strips 49.
  • the outer kelly rod 42, the intermediate kelly rod 48 and the inner kelly rod 50 are each axially displaceable with respect to one another, with the torque in a basically known manner from the outer kelly rod 42 to the intermediate kelly rod 48 and from this to the inner kelly rod 50 independently of the respective via axial inner drive strips (not shown) axial position can be transmitted.
  • locking pockets can be provided on the individual rod elements, so that in a locked state, axial forces can also be transmitted to a certain extent via the Kelly rod arrangement 40.

  • a damping device 56 can be provided at the lower end region 54 of the inner kelly rod 50, as shown in FIG Figures 2 and 3 is shown. The damping device 56 can serve to dampen axial impacts when the Kelly bar arrangement 40 is telescoped in and out or when the soil cultivation tool 26 is placed on the ground.
  • the inner kelly bar 50 and thus the kelly bar arrangement 40 as a whole are suspended from the support cable 30 by means of the cable suspension 60.
  • the support cable 30 is provided with a cable eye 63, which is connected to an upper articulation area 62 of the cable suspension 60 via a transverse retaining bolt 61.
