Abstract

The device has a special cup-telescope boring device, with at least one motor for rotating and thrusting the borer tool and a display and recording unit. The drive unit (6) moves the borer tool into the telescope and at the same time drives the borer tool into the cup bases (2). The cups fit exactly into each other and are driven by each other.

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 for many Years, for example, applied to trees and structures. A drive turns and pushes it Drilling tool from a drill into the material to be examined, for example a tree or wood. For example, the performance or Power consumption of the drilling tool drive when penetrating and pulling out as a measure of the drilling resistance and thus as a parameter for the identification and evaluation of Material properties of the test object.

Als Bohrwerkzeuge werden mitunter sehr dünne Stahldrähte mit einer Länge von bis zu über einem Meter verwendet, sodaß im antreibenden Bohrgerät die Notwendigkeit der seitlichen Abstützung entsteht.Very thin steel wires with a length of up to over are sometimes used as drilling tools one meter used, so in the driving drill the need for lateral Support arises.

Bisherige Bohrgeräte bestehen meist aus einem konstruktiven Kern, umgeben von einem Gehäuse. Eine Konsequenz hieraus ist eine fixierte Gerätelänge sowie eine beschränkte, maximal mögliche Bohrtiefe.Previous drilling devices usually consist of a structural core, surrounded by one Casing. One consequence of this is a fixed device length and a limited, maximum possible drilling depth.

Hier wird nun erstmals ein Spezial-Becher-Teleskop als Führung und Gehäuse zugleich verwendet. Exakt ineinander passende Becher (1) werden als Teleskop angeordnet, mit einer Verdrehsicherung und Führungsschlitzen versehen, damit die Becher beim Auseinanderziehen nicht herausrutschen. Im kleinsten, innersten Becher (3) steckt das Antriebsaggregat (6), vorzugsweise eine geeignete Motor-Getriebe-Kombination, die beim Bohrvorgang quasi in die sich umschließenden Becher einfährt. Schließlich ist als Hubverlust im wesentlichen nur noch die Summe der Dicke der verschiedenen Becherböden (2) zu verzeichnen, welche vielfach geringer ist als bei den früheren Lösungen.Here, for the first time, a special cup telescope is used as a guide and housing at the same time. Cups ( 1 ) that fit exactly into one another are arranged as a telescope, provided with an anti-rotation device and guide slots so that the cups do not slide out when pulled apart. The smallest, innermost cup ( 3 ) contains the drive unit ( 6 ), preferably a suitable motor-gear combination, which virtually moves into the surrounding cup during the drilling process. Finally, the stroke loss is essentially only the sum of the thickness of the different cup bottoms ( 2 ), which is often less than in the previous solutions.

Damit ist das Gerät im Ruhezustand (zusammengeschobenes Becher-Teleskop) sehr kurz, was insbesondere für Verpackung und Transport Vorteile hinsichtlich verbesserter Handhabung und niedrigerer Kosten bringt. Vor den Messungen wird zunächst die benötigte Bohrnadel eingesetzt, dann das Teleskop auf die gewünschte Länge ausgefahren bzw. gezogen.So the device is at rest (collapsed cup telescope) very short what advantages for improved handling and especially for packaging and transport brings lower costs. Before the measurements, the required drilling needle is inserted, then extend or pull the telescope to the desired length.

Das Becher-Teleskop ist dazu so gestaltet, dass die dickste Hülse manuell fixiert werden kann. z. B. mittels Handgriff. Ebenso wird ein Handgriff an den innersten Antriebsbecher angebracht, damit daran gezogen und/oder gedrückt werden kann.The cup telescope is designed so that the thickest sleeve can be fixed manually. e.g. B. by means of a handle. Likewise, a handle is attached to the innermost drive cup, so that it can be pulled and / or pressed.

Seilzug-VorschubCable feed

In einer Ausführungsform des Gerätes laufen ein oder mehrere bis Seil(e) durch alle Becherböden (2). Diese werden auf einer vom Antrieb (z. B. Motor oder nachgeordnetes Getriebe) angetriebenen Walze (4) aufgewickelt und bewerkstelligen damit den Vorschub des Wergzeugs beim Hineinbohren (der Antrieb zieht sich quasi nach vorn). Anschließend wird der Motor manuell herausgezogen, wobei der Griff zum Herausziehen (7) mit dem Seil- Aufwickelmechanismus so verbunden ist, dass dieser beim Zurückziehen des Aggregats von der antreibenden Motor- bzw. Getriebeachse entkoppelt wird.In one embodiment of the device, one or more to rope (s) run through all cup bottoms ( 2 ). These are wound up on a roller ( 4 ) driven by the drive (e.g. motor or subordinate gear) and thus bring about the advance of the tool when drilling into it (the drive almost pulls forward). The motor is then pulled out manually, the pull-out handle ( 7 ) being connected to the cable winding mechanism in such a way that it is decoupled from the driving motor or transmission axis when the unit is pulled back.

Die Messung der jeweiligen Bohrtiefe erfolgt vorzugsweise über das Vorschub-Zug-Seil - entweder z. B. über einen mit dem Seil-Wickel-Mechanismus verbundenen Drehgeber oder über opto­ elektronische Registrierung von Abstands-Markierungen auf dem Seil, wie sie z. B. bei Seilzugdistanzmeßgeräten üblich sind. Der Drehgeber sitzt vorzugsweise auf einer Zwischenachse, auf der das Seil nur eine Windung zurücklegt und damit einer Drehung stets die gleiche Wegstrecke entspricht.The respective drilling depth is preferably measured via the feed-pull cable - either e.g. B. via a rotary encoder connected to the cable winding mechanism or via opto electronic registration of distance markings on the rope, as z. B. at Cable distance measuring devices are common. The encoder is preferably located on one Intermediate axis on which the rope travels only one turn and thus always one turn corresponds to the same distance.

Alternativ zum Seilzug kann auch ein Zahn- oder Glatt-Riemen verwendet werden.As an alternative to the cable, a toothed or smooth belt can also be used.

Manuelle VersionManual version

In einer vereinfachten Geräteversion erfolgt der Vorschub in beide Richtungen manuell. Optional kann der aufgebrachte Druck bzw. Zug per Kraftmeßdose erfaßt und mit einem Zeit- und dem Meßsignal zu einer Gesamtergebnisgröße kombiniert werden.In a simplified device version, the feed takes place in both directions manually. Optionally, the pressure or tension applied can be detected by a load cell and with a Time and the measurement signal can be combined to form an overall result variable.

Variable GerätegrößeVariable device size

Konstruktionsbedingt erlaubt das Becher-Teleskop eine flexible Gestaltung der maximal möglichen Bohrtiefe eines Gerätes. Wird eine größere Bohrtiefe benötigt, kann das Teleskop einfach um die entsprechend notwendige Anzahl an zusätzlichen Bechern verlängert werden. Am Antriebskern des Gerätes sowie den Aufzeichnungseinrichtungen ändert sich dadurch nichts. Einzige Konsequenz ist ein größerer Außendurchmesser.Due to the design, the cup telescope allows flexible design the maximum possible drilling depth of a device. If a greater drilling depth is required, this can be done Simply extend the telescope by the necessary number of additional cups become. The drive core of the device and the recording devices change thereby nothing. The only consequence is a larger outside diameter.

Wird eine kleinere Bohrtiefe benötigt, kann das Teleskop entsprechend weniger weit ausgezogen und eine entsprechend kürzere Bohrnadel verwendet werden. Dies hat den Vorteil, dass an der Spitze abgenutzte Bohrnadeln gekürzt und nach entsprechender Behandlung für geringere Bohrtiefen neu verwendet werden können.If a smaller drilling depth is required, the telescope can be extended less accordingly and a correspondingly shorter drilling needle can be used. This has the advantage that at the Tip worn boring needles shortened and after treatment for less Drilling depths can be used again.

Feste GerätegrößeFixed device size

Für den Fall, dass die Gerätelänge nicht minimiert werden muß, der Vorschub jedoch automatisiert erfolgen soll, kann das Becherteleskop in ein Gehäuse (13) integriert werden und z. B. den Antriebskern (6), der sich mittels Getriebe (10) an einer Spindel (11) oder einer andern gehäusefesten Vorschubeinrichtung entlang zieht, umfassen.In the event that the length of the device does not have to be minimized, but the feed is to be automated, the cup telescope can be integrated into a housing ( 13 ) and z. B. the drive core ( 6 ), which extends by means of gear ( 10 ) on a spindle ( 11 ) or other housing-fixed feed device along.
