Description

Bohrwiderstandmessungen mit dünnen Bohrwerkzeugen oder Bohrnadeln werden seit vielen Jahren beispielsweise an Bäumen und Bauwerken angewendet. Ein Antrieb dreht und schiebt das Bohrwerkzeug aus einem Bohrgerät in das zu untersuchende Material, zum Beispiel einen Baum oder Holz. Gemessen und aufgezeichnet werden dabei beispielsweise der Leistungs- bzw. Stromverbrauch des Bohrwerkzeugantriebes beim Eindringen und/oder Herausziehen als Maß für den Bohrwiderstand und damit als Parameter zur Kennzeichnung und Bewertung von Materialeigenschaften des Prüflings.Drilling resistance measurements with thin drilling tools or drilling needles have been used on trees and structures for many years. A drive rotates and pushes the drilling tool from a drill into the material to be examined, for example a tree or wood. Measured and recorded, for example, the power or power consumption of Bohrwerkzeugantriebes when penetrating and / or pulling out as a measure of the drilling resistance and thus as a parameter for the identification and assessment of material properties of the test specimen.

Weltweit gibt es interessante Anwendungen, die den bisherigen Vorrichtungen verschlossen waren: Messungen im strömenden Regen, beispielsweise in tropischen Wäldern, oder Prüfungen von beispielsweise hölzernen Brückenfundamenten unter Wasser. Hierzu muß das Bohrgerät wasserdicht sein, was bislang nicht gelang.There are interesting applications worldwide that have been closed to the previous devices: measurements in the pouring rain, for example in tropical forests, or tests of, for example, wooden bridge foundations under water. For this purpose, the drill must be waterproof, which has not been successful.

Dichtungen für rein drehende Wellen sind bekannt und seit langem üblich. Schiffsantriebe können z. B. an ihren in das Wasser reichenden Wellen mittels O-Ringen oder ähnlichen Mitteln gegen Wassereintritt abgedichtet werden. Im vorliegenden Falle der Bohrwiderstandsmessungen jedoch bewegt sich die (mitunter auch sehr schnell) rotierende Welle (Bohrer oder Bohrnadel) mit nicht unerheblicher Geschwindigkeit (z. B. 1 m/min) durch die Austrittsöffnung des Bohrgerätes (z. B. Messing-Buchse mit Filzpolster) hinaus und wieder zurück. Erfolgt diese Bewegung im Wasser, versagen die üblichen Dichtungen (z. B. O-Ringe) aufgrund der Kombination von hoher Drehzahl sowie gleichzeitiger translatorischer Bewegung des Bohrwerkzeuges.Gaskets for purely rotating shafts are known and have long been common. Ship propulsion can z. B. be sealed at their reaching into the water waves by means of O-rings or similar means against ingress of water. In the present case of the Bohrwiderstandsmessungen, however, moves the (sometimes very fast) rotating shaft (drill or drill needle) with not insignificant speed (eg 1 m / min) through the outlet opening of the drill (eg brass socket with Felt pad) out and back again. If this movement takes place in the water, the usual seals (eg O-rings) fail due to the combination of high speed and simultaneous translational movement of the drilling tool.

Außerdem wird ja gerade der mechanische Bohr- bzw. Dreh- oder Auszugswiderstand z. B. über die Leistung des Antriebes, über das Drehmoment oder über Druck- bzw. Zugkräfte gemessen. An der Bohrnadel stark reibende Dichtungen (um Wassereintritt zu verhindern) würden hier das Meßergebnis verfälschen oder gar die Meßmethodik unmöglich machen. Also darf die Dichtung gegen Wassereintritt entweder keinen nennenswerten oder zumindest nur einen sehr geringen, im Vergleich zum Meßwert (Bohrwiderstand) vernachlässigbar kleinen, zeitlich konstanten und von der Drehzahl unabhängigen Reibungsanteil beisteuern. Derartige Dichtungen sind auf herkömmlichem Wege nicht verfügbar.In addition, yes just the mechanical drilling or rotary or pull-out resistance z. B. measured on the performance of the drive, on the torque or pressure or tensile forces. At the drilling needle strong rubbing seals (to prevent ingress of water) would falsify the measurement result or even make the measuring method impossible. Thus, the seal against water entry either no significant or at least only a very small, compared to the measured value (Bohrwiderstand) contribute negligibly small, temporally constant and independent of the speed of friction. Such seals are not available by conventional means.

Zur Lösung dieses Problems werden in einer speziellen Ausführung der erfindungsgemäßen Vorrichtung übliche Dichtungskombinationen, z. B. Messing, Gummi- und Kunststoff-Ringe sowie Filzpolster in der stirnseitigen Austrittsöffnung eingesetzt. Diese Dichtungen sitzen relativ locker um die Bohrnadel, so daß sie kaum nennenswerte Reibung erzeugen. Eine Schmierung erfolgt über wasserabweisende bzw. wasserbeständige Schmiermittel, die mittlerweile handelsüblich sind, vorzugsweise z. B. zwischen mehreren O-Ringen.To solve this problem, in a special embodiment of the device according to the invention, conventional sealing combinations, e.g. As brass, rubber and plastic rings and felt pads used in the frontal outlet opening. These seals sit relatively loosely around the drilling needle, so that they generate little appreciable friction. Lubrication takes place via water-repellent or water-resistant lubricant, which are now commercially available, preferably z. B. between multiple O-rings.

Das erfindungsgemäß neue Bohrgerät wird ansonsten luftdicht gefertigt, d. h. alle Stecker bzw. Anschlüsse und Bedienelemente sind wasserdicht.The inventively new drill is otherwise made airtight, d. H. All plugs and connections and controls are waterproof.

Die einzige Öffnung des Gerätes, durch die Luft oder Wasser in das Innere eintreten können, ist damit die Austrittsöffnung der Bohrwerkzeuge. Damit durch diese Öffnung beim Bohren kein Wasser eintritt, wird im Inneren des Bohrgerätes ein erhöhter Innendruck aufgebaut. Dazu kann Luft, ein Gas oder ein Gasgemisch verwendet werden (im nachfolgenden vereinfacht nur ,Luft'). Die Luft kann dann, wenn überhaupt, nur neben der Bohrnadel aus dem Bohrgerät austreten, je nach Druckverhältnissen zwischen Innen und Außen. Wird das Bohrgerät unter Wasser verwendet, kann der Luftdruck der jeweiligen Wassertiefe entsprechend angepaßt werden, um Wassereintritt entlang der Bohrnadel an der Geräteaustrittsöffnung zu verhindern. Um möglichst lange Tauchzeiten zu ermöglichen, wird der innere Überdruck gerade so eingestellt, dass er ausreicht, Wassereintritt zu verhindern. Die Druckluft im Bohrgerät kann z. B. aus einer dort angebrachten Gaskartusche (z. B. mit CO2 oder Druckluft) kommen oder über einen entsprechenden Schlauch eingeblasen werden.The only opening of the device through which air or water can enter the interior is thus the outlet opening of the drilling tools. So that no water enters through this opening during drilling, an increased internal pressure is built up inside the drill. For this purpose, air, a gas or a gas mixture can be used (in the following simplified only 'air'). The air can then, if at all, only emerge from the drill next to the drilling needle, depending on the pressure conditions between inside and outside. If the drill is used under water, the air pressure of the respective water depth can be adjusted accordingly to prevent water ingress along the drill needle at the device outlet opening. To allow as long as possible dive times, the internal pressure is just adjusted so that it is sufficient to prevent water ingress. The compressed air in the drill can z. B. come from a gas cartridge installed there (eg, with CO2 or compressed air) or be blown through a hose.

Wenn das Gerät mit einer Kabelverbindung zum Akkupack versehen ist, kann die Druckluftversorgung parallel hierzu erfolgen. Sind die Versorgungs-Akkus im Bohrgerät integriert oder angeflanscht, kann gleiches mit einer Gas-Kartusche erfolgen.If the device has a cable connection to the battery pack, the compressed air supply can be parallel to this. If the supply batteries are integrated or flanged in the drill, the same can be done with a gas cartridge.
