Description
Die Erfindung betrifft eine Rammbohrvorrichtung gemäß Anspruch 1 sowie ein Verfahren zum Herstellen einer Rammbohrvorrichtung gemäß Anspruch 8.The invention relates to a ram boring device according to
Rammbohrvorrichtungen sind aus dem Stand der Technik bekannt und werden insbesondere für die Herstellung von horizontalen Erdbohrungen verwendet. Bei Rammbohrvorrichtungen handelt es sich um selbstgetriebene Bohrvorrichtungen. In der Regel weist eine derartige Rammbohrvorrichtung einen Schlagkolben auf, der innerhalb eines Gehäuses oszillierend (hin- und her-) bewegt wird und dabei, je nach gewünschter Bewegungsrichtung der Rammbohrvorrichtung, auf eine vordere oder hintere Schlagfläche des Gehäuses prallt. Die dabei übertragene kinetische Energie des Schlagkolbens sorgt für eine Beschleunigung der Rammbohrvorrichtung innerhalb des Erdreichs.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. In general, such Rammbohrvorrichtung 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.
Eine derartige Rammbohrvorrichtung ist beispielsweise aus
Der Erfindung liegt nun die Aufgabe zugrunde, eine Rammbohrvorrichtung und ein Verfahren zum Herstellen einer Rammbohrvorrichtung dahingehend zu verbessern, dass ein einfacherer Aufbau ermöglicht wird.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.
Diese Aufgabe wird durch den Gegenstand der nebengeordneten Ansprüche gelöst. Vorteilhafte Ausführungsformen sind in den Unteransprüchen beansprucht und ergeben sich aus der nachfolgenden Beschreibung der Erfindung.This object is achieved by the subject matter of the independent claims. Advantageous embodiments are claimed in the subclaims and will become apparent from the following description of the invention.
Kern der Erfindung ist es, in dem Aufschlagabschnitt des Kolbens im Gehäuse einen Ringeinsatz vorzusehen, der den offenen Querschnitt des Gehäuses im Bereich des mit dem Schlagkolben beaufschlagbaren Endes einer Bohrkopfspitze verkleinert.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 Bohrkopfspitze acted upon by the percussion piston.
Es wurde erkannt, dass ein mit dem Schlagkolben beaufschlagter Abschnitt des Gehäuses, der die Aufschlagsfläche für den Schlagkolben aufweisen kann, trotz der hohen mechanischen Beanspruchung nicht aus einem Stück mit dem Gehäuse bestehen muss. Erfindungsgemäß kann die Außen- und Innenkontur des Rammbohrgerätes getrennt von dem eingesetzten bzw. einzusetzenden Ringeinsatz hergestellt werden. Bisherige Überlegungen zielten darauf, dass der gesamte vordere Teil aus einem höherwertigen Material mit einer einstückigen Verbindung zwischen der Außenkontur und der Aufschlagsfläche für den Kolben gefertigt sein muss. Diese eingefahrenen Überlegungen wurden überwunden. Der Ringeinsatz ist im Gehäuse derart angeordnet, dass er zumindest einen Teil der Energie des Schlagkolbens auf das Gehäuse überträgt. Der Ringeinsatz kann selbst eine Aufschlagfläche für den Schlagkolben aufweisen und derartig die mechanische Energie des auf die Aufschlagfläche auftreffenden Schlagkolbens übertragen. Die mechanische Energie kann auch indirekt beispielsweise mittels Bohrkopf oder Bohrspitze, der bzw. die vom Schlagkolben beaufschlagt wird, auf den Ringeinsatz übertragen werden.It has been recognized that a section of the housing which is acted upon by the percussion piston and which may have the striking surface for the percussion piston does not have to be made in one piece with the housing despite the high mechanical stress. According to the invention, 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.
Dadurch lässt sich das bekannte Reibschweißen erfindungsgemäß vermeiden. Das bietet mehrere Vorteile. Das Gehäuse kann beispielsweise aus einem Rohr gefertigt werden. Ein aufwendiges und teures Ausdrehen einer Reibschweißnaht ist nicht mehr erforderlich. Ein bisher an Drittunternehmen beauftragtes Reibschweißen kann entfallen. Die Herstellungszeit wird verringert. Die sonst erforderlichen mechanischen Bearbeitungen - z.B. Honen nach dem sonst üblichen Reibschweißen - sind nicht mehr notwendig.As a result, the known friction welding can be avoided according to the invention. This offers several advantages. 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.
Der Ringeinsatz kann im Bereich der Aufschlagsfläche für den Schlagkolben angeordnet sein. Der Ringeinsatz kann ferner die Aufschlagsfläche für den Schlagkolben des Rammbohrgeräts aufweisen. Der entsprechende Gehäuseabschnitt muss dann nach Einbringen des Ringeinsatzes nicht mehr mechanisch bearbeitet werden. Der Ringeinsatz kann auch starr oder beweglich mit der Bohrkopfspitze verbunden sein, wobei auch die Bohrkopfspitze die Aufschlagsfläche für den Schlagkolben aufweisen kann, die ihrerseits die mechanische Energie des Schlagkolbens auf den Ringeinsatz und damit auf das Gehäuse überträgt.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.
Unter "Rammbohrvorrichtung" wird insbesondere jedes Gerät verstanden, welches in einem bestehenden oder zu erstellenden Kanal stoßweise bewegt wird, um eine Bohrung zu erstellen oder aufzuweiten oder ein bestehendes Rohr zerstörend oder nicht zerstörend zu ersetzen oder zu reinigen, Leitungen in bestehende Rohre oder andere Langkörper einzuziehen sowie sämtliche Vorrichtungen für Bauarbeiten des unterirdischen Vortriebs. Eine erfindungsgemäße Rammbohrvorrichtung kann insbesondere ein selbstgetriebenes Schlaggerät zur Erstellung einer Horizontalbohrung sein.By "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.
Der Begriff "Rammbohrvorrichtung" umfasst sowohl Erdverdrängungsvorrichtungen, bei denen die Bohrkopfspitze fest mit dem Gehäuse verbunden ist als auch Rammbohrvorrichtungen mit axial, unabhängig vom Gehäuse verschiebbar gelagerter Bohrkopfspitze. Bei der Bohrkopfspitze kann es sich insbesondere um einen Meißel handeln. Eine erfindungsgemäße Rammbohrvorrichtung kann sowohl eine Ein-Takt-Vorrichtung als auch eine Zwei-Takt-Vorrichtung sein. Bei einer Zwei-Takt-Vorrichtung schlägt zunächst der Schlagkolben auf die Bohrkopfspitze, die im ersten Takt vorauseilt. Das Gehäuse wird im zweiten Takt vom Schlagkolben beaufschlagt. Spitzenwiderstand und Mantelreibung werden bei einer Zwei-Takt-Vorrichtung getrennt und abwechselnd leichter überwunden. Bei einer Zwei-Takt-Vorrichtung erfolgt eine bessere Energieumsetzung, die insbesondere die Zertrümmerung von Hindernissen infolge der Konzentration des Schlagimpulses auf die Bohrkopfspitze erleichtert. Infolge der entsprechend dem Hubweg des Bohrkopfes vorauseilenden Bodenverdrängung bleibt das Gehäuse in ruhiger Lage und gewährleistet dadurch eine relativ gute Laufstabilität.The term "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. In 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. In a two-stroke device, 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.
Die Rammbohrvorrichtung im Sinne der Erfindung ist nicht auf unterirdische Erdarbeiten beschränkt. So können beispielsweise Leitungen, in denen ein Erdbohrgerät betrieben wird, auch oberirdisch verlaufen.The ram boring device according to the invention is not limited to underground earthworks. Thus, for example, lines in which a Erdbohrgerät is operated, run above ground.
Der Begriff "Horizontalbohrung" im Sinne der vorliegenden Erfindung erfasst insbesondere jede Art von bestehenden oder zu erstellenden, vorzugsweise horizontalen Kanälen in einem Körper, insbesondere Erdkanäle einschließlich Erdbohrungen, Felsbohrungen oder Erdleitungen sowie unterirdische oder oberirdische Rohrleitungen und Abwasserkanäle, die sich durch Einsatz einer entsprechenden Rammbohrvorrichtung herstellen, aufweiten, zerstören, aufschneiden oder reinigen lassen.The term "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 Rammbohrvorrichtung make, widen, destroy, cut or clean.
Der Begriff "Ringeinsatz" ist nicht auf eine klassische Ringform beschränkt. Er kann also auch eine andere Form als die Kreisform aufweisen oder unterbrochen sein. Insbesondere kann der Ringeinsatz eine äußere Konturform aufweisen, die im Wesentlichen der Innenkonturform des Abschnitts entspricht, in den der Ringeinsatz eingesetzt ist. Es kann vorgesehen sein, dass die äußere Konturform des Ringeinsatzes eine Einhüllende aufweist, die im Wesentlichen der Innenkonturform des Abschnitts entspricht, in dem der Ringeinsatz eingesetzt ist. Insbesondere kann der Ringeinsatz eine, vorzugsweise mittig angeordnete, Öffnung aufweisen.The term "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. In particular, 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. In particular, the ring insert may have a, preferably centrally disposed, opening.
Der Ringeinsatz ist im Abschnitt mittels einer Schrumpf-Verbindung gehalten. Hierdurch wird eine sehr einfache und kostengünstige Möglichkeit geschaffen, den Ringeinsatz in dem Abschnitt zu fixieren bzw. mit diesem zu verbinden. Bei dieser Ausführungsform der Erfindung weist der Ringeinsatz eine Außenkontur auf, die eine größere Abmessung umfasst als eine entsprechende Abmessung der Innenkontur des Gehäuseabschnitts ohne im Gehäuseabschnitt angeordneten Ringeinsatz. Der Ringeinsatz kann in den Gehäuseabschnitt eingeführt werden, indem ein Temperaturunterschied zwischen Ringeinsatz und Gehäuseabschnitt erzeugt wird, wodurch der Innendurchmesser temporär vergrößert und/oder die Außenkontur temporär verkleinert wird. Dies kann beispielsweise mittels von außen aufgebrachter Wärme oder von Innen eingeführter Kälte erfolgen. Der Begriff "Schrumpf-Verbindung" umfasst jegliche Art von Verbindung, bei der eine Möglichkeit geschaffen wird, den geringfügig größeren Ringeinsatz in dem Innendurchmesser des Gehäuseabschnitts anzuordnen. Eine Schrumpf-Verbindung entsteht infolge eines Übermaßes der ineinander gesetzten Teile.The ring insert is held in the section by means of 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. In this embodiment of the invention, 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.
Vorteilhafterweise weist der Abschnitt, in dem der Ringeinsatz gehalten wird, einen kreisförmigen Durchmesser auf. Hierdurch kann die Herstellung vereinfacht werden, da der Ringeinsatz zum Abschnitt rotationsinvariant eingesetzt werden kann. Es kann auf eine Vorzugslage beim Einbringen des Ringeinsatzes verzichtet werden.Advantageously, the portion in which the ring insert is held has a circular diameter. As a result, 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.
Der Ringeinsatz kann auch als Teil des Bohrkopfs ausgebildet sein oder separat von diesem vorliegen. Der Ringeinsatz kann endseitig am Bohrkopf angeordnet sein. Insbesondere kann der Ringeinsatz endseitig im Gehäuseabschnitt des Bohrkopfs bzw. der Bohrkopfspitze angeordnet sein. Der endseitig in dem Gehäuseabschnitt angeordnete Ringeinsatz kann vor dem Gehäuseabschnitt für den Schlagkolben eingesetzt sein.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. In particular, the ring insert can be arranged at the end in the housing section of the drill head or the drill head tip. The end arranged in the housing section Ring insert can be used in front of the housing section for the percussion piston.
In einer bevorzugten Ausführungsform weist der Ringeinsatz ein anderes Material als das Gehäuse auf. Hierdurch kann die Möglichkeit geschaffen werden, den einzelnen Anforderungen des Ringeinsatzes, welcher eine Aufschlagfläche für den Schlagkolben aufweisen kann, und des Gehäuses Rechnung zu tragen. Der Begriff "aufweisen" umfasst im Sinne der Erfindung, dass ein Material bzw. eine Komponente vorhanden ist (den reinen Wortsinn des Begriffes), aber auch, dass das in Bezug genommene Element aus dem Material besteht, wobei allfällige Verunreinigungen oder Restbestandteile vorhanden sein können.In a preferred embodiment, the ring insert has a different material than the housing. In this way, the possibility can be created to take into account the individual requirements of the ring insert, which may have an impact surface for the percussion piston, and the housing. The term "comprising" in the sense of the invention includes that a material or a component is present (the pure sense of the term), but also that the element referred to consists of the material, wherein any impurities or residual constituents may be present ,
In einer bevorzugten Ausführungsform weist die Rammbohrvorrichtung einen Ringeinsatz auf, der ein Material umfasst, welches wärmebehandelt ist. Mittels der Wärmebehandlung können beispielsweise unterschiedliche Eigenschaften eingestellt werden, je nachdem, welche Wärmebehandlung des Materials durchgeführt wurde. Unterschiedliche Wärmebehandlungen können zu unterschiedlichen Eigenschaften führen. Die Wärmebehandlung kann derart sein, dass eine durchgreifende Gefügeumwandlung (Glühen oder Härten) und/oder lediglich eine Umwandlung an der Oberfläche eines Werkstücks (Diffusions- oder Beschichtungsverfahren) bewirkt wird. Die unterschiedlichen Wärmebehandlungen können beispielsweise mittels eines Schliffbildes nachgewiesen werden.In a preferred embodiment, the ram boring apparatus comprises a ring insert comprising a material which is heat treated. By way of example, different properties can be set by means of the heat treatment, depending on which heat treatment of the material has been carried out. Different heat treatments can lead to different properties. The heat treatment may be such as to cause a sweeping microstructural transformation (annealing or hardening) and / or only a transformation on the surface of a workpiece (diffusion or coating process). The different heat treatments can be detected for example by means of a micrograph.
