Definitions

  • the invention relates to a telescoping drill pipe with at least two mutually displaceable Kelly rods, which have means for transmitting a torque to the adjacent Kelly rod.
  • Such telescopic drill pipes are needed for the so-called Kellybohrclar, which is one of the most flexible techniques, for example, for the production of foundation piles for buildings.
  • the Kelly linkage consists of several nested tubular Kelly rods, the innermost of which hangs on a rope of the device and thus can be moved up and down. This telescopes the kelly linkage. At the bottom of the innermost kelly bar, the drilling tool is attached.
  • the torque can be transmitted in every extended state of the Kelly bar.
  • the Kelly bars are either at the bottom stop on the next inner Kelly bar or they hang with their upper stop on the next outer.
  • the torque is transmitted in all Kelly rods at the top or at the bottom. Only one kelly tube at a time - the outermost of those resting on the bottom of the innermost tube - engages the kelly driver of the next outer tube somewhere between the top and bottom into the kelly bars, where it transmits the torque.
  • Kelly linkage steel As a material for Kelly linkage steel is used in suitable alloys to ensure the necessary strength during operation.
  • the torque to be transmitted dimensioned while diameter and thickness of Kelly bars.
  • a relatively high weight of the Kelly linkage can result. This is not only important for the design of the necessary winches and drives, but also for the statics of the mast, on which the drill pipe is hung. Since the drilling axis must be located in front of the tracks of the drill due to the design, a heavy kelly linkage means a correspondingly high tilting moment of the device. This must then be ballasted correspondingly high for a sufficient stability, which in turn requires a larger and more stable tracked vehicle. This leads to higher costs and restrictions on the transport and positioning of the drill.
  • the invention has for its object to provide a telescopic drill pipe, which allows an efficient and inexpensive drilling operation.
  • the invention is characterized in that at least one of the kelly bars is made up of at least two bar segments made of different materials.
  • a basic idea of the invention is based on the recognition that regions with different function and load are present on a Kelly bar. According to the invention, areas of high stress and surface pressure can be made of a correspondingly high strength material, while areas of lower stress and surface pressure are made of a simpler material. This allows a functional and needs-based design of the Kelly linkage, with high-strength and mostly expensive material can be saved.
  • a material of the rod segments is a lightweight material, especially carbon fiber reinforced plastic. It can also be used other lightweight materials, such as light metals.
  • carbon fiber reinforced plastic allows a sufficiently high torque and Axialkraftübertragung.
  • a correspondingly high-strength and heavy material such as steel in a corresponding alloy can be used.
  • the means for transmitting the torque or the force is formed on a rod segment, which is made of a steel material.
  • a rod segment which is made of a steel material.
  • the upper and / or the lower end of the Kelly rod is formed on a rod segment of a steel material.
  • further transmission means can be arranged.
  • the lying between the rod segments of the steel material other rod segments can be made from the lightweight material.
  • the individual Kelly rods are tubular, the mecanickelly can also be a solid rod.
  • the individual kelly bars can have any cross section.
  • a particularly favorable ratio between weight and torsional rigidity results according to the invention in that the rod segments are tubular with an annular cross-section.
  • An annular cross section offers above all for the lightweight construction segments From a carbon fiber reinforced plastic a particularly high torsional stiffness.
  • the rod segments have means for transmitting an axial force to adjacent rod segments.
  • the means for transmitting an axial force are formed together with the means for transmitting a torque, for example as so-called locking pockets.
  • a particularly robust drill pipe results according to the invention in that the means for transmitting a torque and / or the means for transmitting an axial force have positive locking elements.
  • the positive locking elements comprise stop strips, locking pockets and / or driving grooves.
  • the positive locking elements comprise stop strips, locking pockets and / or driving grooves.
  • the outer Kelly bar is made entirely of metal.
  • the outer kelly bar is by a variety of means provided for transmitting a torque and / or an axial force, which are arranged at different heights.
  • the outer Kelly bar can also allow over its entire length a torque transmission. In this way, in the other Kelly rods, the number of means for transmitting torque or for axial force transmission can be limited to two.
  • the outermost Kelly bar When lowering the Kelly linkage then the outermost Kelly bar must first be locked at the appropriate height to the rotary drive. This can be done passively by a bayonet-type similar mechanism or actively by a rotary drive mechanism. Thereafter, the Kelly linkage is drained again so that all other Kelly rods are either fully or not at all extended. In addition, a very good passive protection of the retracted drill string is ensured by a complete execution of the outer Kelly bar.
  • FIG. 1 and 2 illustrates a simple telescoping drill pipe 10 having a first, inner Kelly bar 20 and a second outer Kelly bar 40.
  • the inner Kelly bar 20 is constructed of three tubular segments, an upper segment 22, a lower segment 24 and an intermediate intermediate segment 26.
  • In the upper segment 22 and in the lower segment 24 are each a plurality of means 27 for torque and axial force transmission along the circumference.
  • the lower segment 24 has for this purpose axially extending stop strips 28, which is bounded at each of its two ends to one side by axial stops 30a, 30b.
  • axial stops 30a, 30b By the stop bar 28 and the two adjacent and spaced-apart axial stops 30a, 30b, a locking pocket 32 is formed, in which a driver of the adjacent Kelly bar can be accommodated.
  • the two axial stops 30a, 30b spaced from defined by the next stop bar 28, wherein a recess 31 is formed for the axial passage of the driver.
  • the means 27 for torque and force transmission is formed in a similar manner, but only a single axial stop 30c at the lower end of the stop bar 28 is arranged.
  • the upper segment 22 and the lower segment 24 with the stop strips 28 formed thereon and axial stops 30 are made of a steel material which ensures the necessary strength, in particular for the stop bar 28 and the axial stops 30 during the power transmission between the individual kelly bars 20, 40.
  • the middle segment 26 for weight saving made of a lightweight material, in particular a carbon fiber reinforced plastic manufactured.
  • the tubular central segment 26 is fixedly connected at its two free ends to the upper segment 22 and the lower segment 24 via suitable connecting means.
  • axially running guide rails 34 can be attached, which are not used for torque transmission but for guided telescoping.
  • axial guide elements 42 are provided with guide grooves introduced therein, in which the guide rails 34 engage.
  • at least one driver 44 is arranged on the inside of the outer Kelly bar 40 for torque transmission.
  • the driver 44 passes through the recess 31 in the region of the locking pocket 32 on the lower segment 24 of the inner Kellystange 20.
  • a torque or axial force transmission between the two adjacent Kelly rods 20, 40 take place.
  • a tool holder not shown, is provided on the inner Kellystange 20 .
  • the kelly linkage according to the invention is suitable not only for receiving drilling and milling tools but also for other soil cultivation tools, such as grippers.
