Definitions

  • the invention relates to a Erdbohrvorraum and a method for moving BohrgestCodeschiffn.
  • Erdbohrvoriquesen in particular horizontal drilling, are used to bring in trenchless construction Erdbohrungen example for supply and disposal lines in the ground or already laid old lines trenchless exchange.
  • a BohrgestSheschadore exhibiting drill pipe is used, in which the BohrgestSheschadore are connected to each other.
  • the carriage has a receptacle for a Bohrgestfiteschuss, so that the BohrgestSheschuss can be moved in the direction of a feed axis for creating the Erdbohrung in the recording.
  • the drive acting on the BohrgestSheschuss can act rotationally and / or translationally on the Bohrgestfiteschuss in the recording.
  • US 2,165,666 A discloses a horizontal drilling apparatus in which a frame is provided to which another frame is attached. The further frame is hinged to the frame on a pivot axis. In the second frame, a carriage can be moved longitudinally. After retraction of the carriage, the carriage and the other frame can be inclined relative to the feed axis.
  • the disadvantage here is that especially in a frame located in a pit frame and arranged therein the compact design of the frame with the carriage difficult handling when inserting and / or removing a Bohrgestfiteschusses from the recording of the carriage. Furthermore, the size of the frame or of the travel path of the carriage in the frame specifies the maximum size of the drill string sections to be connected to each other, which requires restrictions, although the longest possible drill rod sections are desired.
  • the invention therefore an object of the invention to provide an improved Erdbohrvorraum, with the improved handling of introduced into the soil BohrgestSheschadore is simplified and / or a strict restriction of BohrgestSheschusseria can be lifted to a clear length in the frame. Further, an improved method of connecting drill string sections should be provided which facilitates handling of the drill string sections.
  • the core idea of the invention is to improve the access to the carriage or the linkage receiving the carriage for the BohrgestSheschadore thereby that the access to the carriage from the side by means of a tilting device, which causes the carriage in the According to the invention it was first recognized that contrary to the view that a particular stability and linear guidance of the carriage must be ensured in the frame, a tilting device for the movement of the carriage brings benefits due to the above prejudice were considered unreachable.
  • the carriage can be tilted backwards relative to the feed axis.
  • the tilting device allows tilting of the carriage so that the carriage or the receptacle of the carriage can be accessed from above improved. Due to the inclination of the carriage to the rear, a new introduced into the soil drill pipe without hindrance introduced into the rear of the carriage and connected to the receptacle, which in turn is connected to the drive become.
  • the Erdbohrvorraum can be built very short, which concerns in particular the extension in the longitudinal direction of the frame. The use in very small excavation pits may be possible.
  • Erdbohrvorraum is in particular any device understood that a BohrgestCodeschadore having BohrgestShe moved in an existing or to be created channel in the ground to create a bore, in particular a horizontal bore (HD), or expand lines or other long body in to collect the soil.
  • the earth boring device may in particular be an HD device.
  • An "earth boring device” according to the invention comprises a device which drives a drill pipe and works in a soil-displacing manner, and introduces the drill pipe into the earth in a rotational and / or translatory manner in the longitudinal axial direction of the drill string.
  • HD horizontal drilling, horizontal drilling
  • a body in particular earth channels including earth boreholes, rock holes or ground lines and underground or above-ground pipelines and water channels can be made or retracted by using a suitable earth drilling device,
  • feed axis comprises the axis along which the borehole to be created runs.
  • feed axis it is irrelevant whether the drill pipe is pushed through the soil during the creation of the well bore and / or pulled.
  • the force acting on the drill string along the bore to be created may be a tensile force and / or a compressive force or thrust.
  • the drill pipe can be pulled and / or pushed through the soil by means of the carriage or the receptacle arranged in the carriage.
  • the drill string can also be impressed with a rotational movement about the longitudinal axis.
  • the term "carriage” comprises a body with a receptacle for a BohrgestSheschuss, wherein by means of recording the BohrgestSheschuss can be driven translationally and / or rotationally.
  • the Carriage be guided in the frame for a translational movement along a path.
  • the carriage can rest on a frame connected to the support with embarks instituten.
  • the support can be profiled and the Aufstandssel Düsseldorf can be designed as rollers.
  • the carriage can be guided on the frame hanging and / or resting.
  • the carriage can thus be a machine element which can be moved along a path, in particular purely translationally, in the frame.
  • the term "frame” according to the invention comprises a box-shaped or parallelepiped structure whose side walls and / or struts or bars can transmit pressure, tension and also bends.
  • the frame according to the invention preferably has a quadrangular elevation and can be placed in a pit to create the wellbore.
  • drive unit and slide are arranged in the frame.
  • the frame can be provided with horizontally extendable clamping supports, via which the recoil forces can be introduced into the soil.
  • the tilting means comprises a guide for the carriage, which is inclined in an end region of the frame relative to the feed axis.
  • the inclination of the guide closes with the feed axis an angle greater than 0 ° and less than 90 °, in particular between 3 ° to 7 °.
  • the end region of the frame in which the tilting means is formed is preferably located at the end of the frame which is spaced from the borehole to be created.
  • the guide has two sections which enclose an angle to one another, wherein the two sections can be linearly extending sections, in particular one of the sections can be formed parallel to the feed axis.
  • the further section includes an angle greater than 0 degrees and less than 90 degrees with the section parallel to the feed axis.
  • the guide comprises a support, which has an inclination in the end region.
  • the support may be designed for corresponding elements of the carriage.
  • a support without head-side guidance of the elements of the carriage can also allow that no positive guidance in height is achieved, but the carriage just rests and not pressed down. This can be particularly advantageous if, for example due to an error in the operation of Erdbohrvoriques it comes that the drill string located in the carriage is connected to a still remaining in the soil BohrgestCodeschuss. In such a case, a forced operation would lead to damage of the BohrgestSheschusses or the linkage and / or the carriage. If the carriage is only on a guide, stabilization can be achieved by holding the carriage away from the drill pipe in a position where the carriage will not tip.
  • the tilting device or guide can be designed to be open on the head side.
  • the guide extends in a plane, so that the tilting device or the guide only causes a tilting in the vertical direction and tilting or tilting or pivoting of the carriage in the horizontal direction does not happen.
  • the guide has two spaced-apart guide elements, which are aligned parallel to the feed axis.
  • the degree of freedom of tilting the tilting device is thus limited to tilting in the vertical direction, which can limit the degrees of freedom of the guide and a simple guide can be created.
  • the guide can be formed or fastened to the selw walls of the frame, which are usually oriented parallel to the feed axis.
  • the guide of the carriage is such that the carriage is tilted in the end region in a plane which intersects the propulsion axis.
  • the number of degrees of freedom of the tilting device or guide can thereby be reduced.
  • the tilting takes place in the vertical direction.
  • a tilting In the horizontal direction can be omitted.
  • the guide is profiled, so that the guide may have a profiled support in the uprising elements of the carriage, such as rollers, can be performed. Due to the profiling, a stable run of the carriage when moving back and forth can be achieved.
  • the profile not only a guide with respect to the height of the support or the tilting is possible, but also a stabilization in the direction of movement along the extension of the guide or support.
  • the distance between supported by the guide riot elements of the carriage in the direction of the feed axis is greater than the length of the inclined guide in the end region.
  • the invention also provides a method of moving a drill string, the method comprising the steps of: moving a carriage to move a drill string in a frame, the direction being opposite to the direction of the feed; Tilting the carriage when moving back; Inserting a drill string in the tilted carriage; and moving the carriage with the drill string in the direction of the feed.
  • the carriage is tilted in an end region of the frame, particularly preferably on the side remote from the bore.
  • Fig. 1 shows an earth boring device in an isometric view.
  • the Erdbohrvorraum has a frame 1, which may be arranged in a start or excavation.
  • a carriage 2 is moved back and forth.

  • the Indian Fig. 1 drill string 3 to be seen is located in the soil and in the feed axis of the hole to be created.
  • a tilting device 4 is formed, which causes the carriage 2 to tilt when moving back relative to the feed axis.
  • the Fig. 2 shows the relative to the feed axis inclined carriage 2.
  • the recording of the carriage 2 is inclined relative to the feed axis upwards, wherein the inclination relative to the feed axis may be 2 ° to 40 °, in particular 3 ° to 7 °.
  • a newly introduced into the soil Bohrgestfiteschuss 3 can be used in the recording of the carriage 2.
  • the carriage 2 can then be moved again in the direction of the earth hole to be created and the carriage 2 moves out of its inclined position.
  • the drill string section 3 located in the receptacle of the carriage 2 is aligned with the feed axis and the drill string section 3 located in the receptacle can be connected to the drill string section 3 already bored in the ground.
  • the carriage 2 can then be moved further in the direction of the newly created well bore and brings the in-receiving Bohrgestfiteschuss 3 into the ground.
  • the in the Fig. 1 shown tilting device 4 is designed as a guide 5, which tends the carriage 2 in an end region of the frame 1 relative to the feed axis.
