Definitions

  • the invention relates to a telescopic drill pipe at least two mutually displaceable Kelly rods, which Means for transmitting torque to the adjacent Kelly bar exhibit.
  • Such telescopic drill rods are used for the so-called Kelly drilling process required, which for example for the manufacture of foundation piles for buildings is one of the most flexible Techniques is.
  • the Kelly linkage consists of several nested tubular Kelly rods, the innermost of which is on a rope of the device hangs and can thus be moved up and down.
  • the Kelly linkage telescopes. At the bottom innermost Kelly drill is attached to the drilling tool.
  • each of the Kelly Rod tubes and corresponding vertical driver grooves the adjacent Kelly rod is made according to a shaft-hub connection the torque and thus the rotary movement of transferred from one Kelly bar to another. That way the rotary movement from the rotary gear to the drilling tool in the borehole transfer.
  • the torque can be in any extended state of the Kelly bar be transmitted.
  • the Kelly bars are either at the bottom Stop on the next inner Kelly rod on or with their upper stop they hang on the next outer one.
  • the torque is at the top of all Kelly rods or transmitted at the lower end. Only with one Kelly tube at a time - the outermost of those below on the innermost Put the tube on - the kelly driver of the next outer one grips Rohrs somewhere between the top and bottom of the Kelly strips and transmits the torque there.
  • Lockable Kelly rods In addition to the transmission of the rotary movement, so-called “Lockable Kelly rods” also have a vertical force from the Carriage on which the rotary gear moves up and down the mast, transferred to the drilling tool via the Kelly linkage in order to generate the contact pressure necessary to remove the soil. To are on all Kelly poles at certain intervals Locking pockets attached.
  • Kelly rods used to provide the necessary strength in operation guarantee.
  • the torque to be transmitted is dimensioned the diameter and thickness of the Kelly rods.
  • a relatively high weight of the Surrender to Kelly's rod This is not just for design the necessary winches and drives, but also for the statics of the mast on which the drill pipe is suspended becomes.
  • As the drilling axis is due to the construction in front of the caterpillars of the Drill must lie, means a heavy Kelly rod a correspondingly high overturning moment of the device. This must be for sufficient stability is then ballasted accordingly become what in turn a larger and more stable crawler vehicle requires. This leads to higher costs and restrictions when transporting and positioning the drill.
  • the invention has for its object to provide a telescopic drill pipe, which allows efficient and inexpensive drilling operation.
  • the invention is characterized in that at least one the Kelly rods are made up of at least two rod segments which is made of a different material are.
  • a basic idea of the invention is based on the knowledge that that on a Kelly rod areas with different Function and load are present. According to the invention can identify areas with high loads and surface pressure a correspondingly high-strength material, while Areas with lower loads and surface pressure a simpler material. This makes possible a functional and needs-based construction of the Kelly boom, being high-strength and mostly also expensive material can be saved.
  • the means for transmitting the Torque or the force formed on a rod segment which is made of a steel material. preferably, it is provided that the upper and / or the lower End of the Kelly bar on a bar segment from one Steel material is formed.
  • the torque and Power transmission in one or more intermediate Sections can be arranged further transmission devices become.
  • the between the rod segments made of the steel material lying other rod segments can from the lightweight material.
  • the individual Kelly rods are tubular due to their function trained, the inner kly also a solid rod can be.
  • the individual Kelly rods can be any Have cross-section. A particularly favorable relationship between However, weight and torsional stiffness result according to the invention in that the rod segments are tubular with an annular cross section are formed. On circular cross section offers especially for the lightweight construction segments made of a carbon fiber reinforced plastic particularly high torsional rigidity.
  • the drill pipe according to the invention in that the rod segments provide means for transmitting an axial force have adjacent rod segments.
  • the agents are preferred for transmitting an axial force together with the medium for transmitting a torque, for example as a so-called Locking pockets, trained.
  • a particularly robust drill pipe results from the invention in that the means for transmitting a torque and / or the means for transmitting an axial force Have positive locking elements.
  • the form-locking elements preferably comprise stop strips, Locking pockets and / or driving grooves. Overall will so between the individual Kelly rods a torque and Power transmission as with known shaft-hub connections, reached.
  • the rod segments are made of lightweight material no torque and power transmission immediately from a neighboring Kelly bar, as this is particularly high Surface pressure leads.
  • Such rod segments can thus smooth surface on the outside as simple pipes his.
  • Axial guide rails made of lightweight material are provided on the rod segment. Since this is not for direct power transmission are provided, the guide rails can be retrofitted suitable connecting devices attached to the rod segments become.
  • the outer Kelly bar is made entirely of metal.
  • Prefers is the outer Kelly bar with a variety of means for transmitting a torque and / or an axial force provided, which are arranged at different heights.
  • the outer Kelly bar can also be one over its entire length Allow torque transmission. That way, at the other Kelly rods the number of means for torque transmission or limited to two for axial force transmission become.
  • the outermost must Kelly rod first at the appropriate height for the rotary drive be locked. This can be done passively through a bayonet-type lock Mechanism done or active by means of a mechanism originating from the rotary drive. After that the Kelly linkage is lowered so that everyone else Kelly rods are either fully or not at all extended.
  • by a complete execution of the outer Kelly bar also a very good passive protection of the retracted Drill pipe guaranteed.
  • the invention provides a simple telescopic drill string 10 with a first, inner Kelly rod 20 and one second outer Kelly rod 40.
  • the inner Kelly rod 20 is made up of three tubular segments, an upper one Segment 22, a lower segment 24 and an intermediate middle segment 26.
  • In the upper segment 22 and in the lower Segment 24 are several means 27 for torque and axial power transmission arranged along the circumference.
  • the lower segment 24 has stop strips running axially 28 on, which at both ends to one Side is limited by axial stops 30a, 30b.
  • axial stops 30a, 30b By the stop bar 28 and the two adjacent and to each other spaced axial stops 30a, 30b becomes a locking pocket 32 formed, in which a driver of the adjacent Kelly rod can be included.
  • the two axial stops 30a, 30b from the next stop bar 28 defines spaced apart, with a recess 31 is formed for the axial passage of the driver.
  • the means 27 for torque and Power transmission formed in a corresponding manner, wherein however, only a single axial stop 30c at the lower end of the Stop bar 28 is arranged.
  • the upper segment 22 and that lower segment 24 with the stop strips formed thereon 28 and axial stops 30 are made of a steel material, which has the necessary strength especially for the Stop bar 28 and the axial stops 30 in the power transmission guaranteed between the individual Kelly rods 20, 40.
