Definitions

  • the invention relates to a ram boring device according to claim 1 and to a method for producing a ram boring device according to claim 8.
  • Ramm boring devices are known in the art and are used in particular for the production of horizontal wells.
  • Ramm boring devices are self-propelled boring devices.
  • such Rammbohrvorraum has a percussion piston which is oscillated (reciprocating) within a housing and thereby, depending on the desired direction of movement of the ram boring device, bounces on a front or rear impact surface of the housing.
  • the transmitted kinetic energy of the percussion piston ensures an acceleration of the ram boring device within the soil.
  • DE 10 2010 015 465 A1 has a Erdbohrvortechnisch as Rammbohrvortechnisch for drilling in the ground, which has at least one housing portion for a percussion piston.
  • Such a ram boring device is for example made DE 10 2009 038 383 A1 known.
  • the case of the DE 10 2009 038 383 A1 known Rammbohrvorraum is made of two parts. In one part, ie the rear part, the percussion piston oscillates. The other part, ie the front part, has the drill head and is acted upon by the percussion piston. The two parts are joined together by friction welding.
  • the rear part is a tube made of structural steel, which for the production of a housing portion of a ram boring a having predetermined inner diameter.
  • the front part is usually made of solid and is made of high quality steel, since the forces of the percussion piston act.
  • the friction weld After friction welding, the friction weld must be turned out consuming, so that the piston can be moved forward without an obstacle. After unscrewing the friction weld, the outer contour of the housing is also finished, so that all threads and other contours lie on one axis.
  • the invention is based on the object of improving a ram boring device and a method for producing a ram boring device such that a simpler structure is made possible.
  • the essence of the invention is to provide a ring insert in the impact section of the piston in the housing, which reduces the open cross-section of the housing in the region of the end of a Bohrkopf dictate acted upon by the percussion piston.
  • the outer and inner contour of the ram boring machine can be produced separately from the ring insert used or to be used. Previous considerations were that the entire front part must be made of a higher quality material with a one-piece connection between the outer contour and the impact surface for the piston. These well-thought-out considerations were overcome.
  • the ring insert is arranged in the housing such that it transmits at least a portion of the energy of the percussion piston to the housing.
  • the ring insert may itself have an impact surface for the percussion piston and in this way transmit the mechanical energy of the percussion piston impinging on the impact surface.
  • the mechanical energy can also be transmitted indirectly, for example by means of a drill head or drill bit, which is acted upon by the percussion piston, on the ring insert.
  • the housing can be made for example of a tube. A costly and expensive turning out a friction weld is no longer necessary. A previously contracted to third party friction welding can be omitted. The production time is reduced. The otherwise required mechanical processing - eg honing after the usual friction welding - are no longer necessary.
  • the ring insert can be arranged in the region of the impact surface for the percussion piston.
  • the ring insert may further comprise the impact surface for the percussion piston of the ram boring machine.
  • the corresponding housing section then no longer has to be machined mechanically after inserting the ring insert.
  • the ring insert may also be rigidly or movably connected to the drill head tip, wherein the drill head tip may have the impact surface for the percussion piston, which in turn transmits the mechanical energy of the percussion piston on the ring insert and thus on the housing.
  • ram boring device is meant, in particular, any device which is intermittently moved in an existing or to-be-created channel to create or expand a bore or destructively or non-destructively replace or clean an existing pipe, conduits into existing pipes or other long bodies as well as all devices for construction work of underground tunneling.
  • a ram boring device according to the invention may in particular be a self-propelled impact device for creating a horizontal bore.
  • ram boring device includes both earth displacement devices in which the drill head tip is fixedly connected to the housing and ram boring devices with axial, independently of the housing slidably mounted Bohrkopfspitze.
  • the bit may in particular be a bit.
  • a ram boring device according to the invention may be both a one-stroke device and a two-cycle device.
  • a two-stroke device initially proposes the percussion piston on the drill head tip, which leads in the first cycle.
  • the housing is acted upon by the percussion piston in the second cycle.
  • Tip resistance and skin friction are separated in a two-stroke device and alternately overcome more easily.
  • there is a better energy conversion which facilitates in particular the destruction of obstacles due to the concentration of the impact pulse on the drill head tip. Due to the anticipated according to the stroke of the drill head soil displacement housing remains in a quiet location, thereby ensuring a relatively good running stability.
  • the ram boring device according to the invention is not limited to underground earthworks.
  • lines in which a Erdbohrêt is operated run above ground.
  • horizontal drilling in the context of the present invention covers in particular any type of existing or to be created, preferably horizontal channels in a body, in particular earth channels including earth boreholes, rock holes or ground lines and underground or above-ground pipelines and sewers, which are characterized by use of a corresponding Rammbohrvorraum make, widen, destroy, cut or clean.
  • ring insert is not limited to a classic ring shape. It can therefore also have a different shape than the circular shape or be interrupted.
  • the ring insert may have an outer contour shape, which substantially corresponds to the inner contour shape of the portion in which the ring insert is inserted. It may be provided that the outer contour shape of the ring insert has an envelope, which corresponds substantially to the inner contour shape of the portion in which the ring insert is inserted.
  • the ring insert may have a, preferably centrally disposed, opening.
  • the ring insert is held in the section by means of a shrink connection.
  • a shrink connection This creates a very simple and cost-effective way to fix the ring insert in the section or to connect with this.
  • the ring insert on an outer contour, which has a larger dimension than a corresponding dimension of the inner contour of the housing portion without arranged in the housing portion ring insert.
  • the ring insert can be inserted into the housing section by creating a temperature difference between the ring insert and the housing section, whereby the inner diameter is temporarily increased and / or the outer contour is temporarily reduced. This can be done, for example, by externally applied heat or cold introduced from the inside.
  • the term "shrink connection" includes any type of connection in which a possibility is provided to arrange the slightly larger ring insert in the inner diameter of the housing portion. A shrink connection arises due to an oversize of the nested parts.
  • the portion in which the ring insert is held has a circular diameter.
  • the production can be simplified, since the ring insert can be used to the section rotationally invariant. It can be dispensed with a preferred situation when introducing the ring insert.
  • the ring insert may also be formed as part of the drill head or be present separately from this.
  • the ring insert can be arranged on the end side of the drill head.
