Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren gemäß dem Oberbegriff des Patentanspruchs 1.The invention relates to a method according to the preamble of patent claim 1.
Bei den bekannten Verfahren wird zum Feststellen des Endzustandes der im Boden erreichten Verdichtung als Maschinenparameter die für die Verdichtungsarbeit maßgebliche Beschleunigung des Verdichtungselementes, im bekannten Falle der vibrierenden Walzen einer Bodenverdichtungswalze, mit Hilfe von Beschleunigungsaufnehmern gemessen. Die gemessene Beschleunigung entspricht dem Ist-Wert der jeweils erreichten Bodenfestigkeit und zeigt dem Bediener an, wann der gewünschte Verdichtungszustand erreicht ist.In the known methods, to determine the final state of the compaction achieved in the soil, the acceleration of the compaction element, which is important for the compaction work, in the known case of the vibrating rollers of a soil compaction roller, is measured with the aid of acceleration sensors. The measured acceleration corresponds to the actual value of the soil strength achieved and shows the operator when the desired compaction state has been reached.
Die zur Durchführung des bekannten Verfahrens erforderlichen Beschleunigungsaufnehmer bilden zusammen mit der zugehörigen Auswertelektronik eine sehr aufwendige und kostenintensive Einrichtung, deren Einsatz deswegen nur bei Großgeräten vernünftig ist.The accelerometers required to carry out the known method, together with the associated evaluation electronics, form a very complex and cost-intensive device, the use of which is therefore only sensible in the case of large devices.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren nach dem Oberbegriff des Patentanspruchs 1 zu schaffen, das mit wesentlich einfacheren und kostengünstigeren Mitteln realisiert werden kann als das bekannte Verfahren und sich daher auch für die Anwendung bei kleinen Geräten wie Bodenverdichtungsplatten, Stampfern, oder dgl. eignet.The invention has for its object to provide a method according to the preamble of claim 1, the Much simpler and less expensive means can be implemented than the known method and is therefore also suitable for use in small devices such as soil compaction plates, rammers or the like.
Die vorstehende Aufgabe wird durch die im Kennzeichnungsteil des Patentanspruchs 1 genannten Merkmale gelöst.The above object is achieved by the features mentioned in the characterizing part of patent claim 1.
Bei dem erfindungsgemäßen Verfahren wird gegenüber dem bekannten Verfahren anstelle der in der gemessenen Beschleunigung zum Ausdruck kommenden Ist-Wertes der Bodenfestigkeit nur die relative zeitliche Veränderung des Verdichtungsgrades festgestellt, wofür als Maschinenparameter die Motorleistung herangezogen werden kann, da Versuche der Anmelderin gezeigt haben, daß die dem Antriebsmotor für die Schwingungserreger abgeforderte Leistung mit zunehmender Bodensteifigkeit abnimmt und ihr zeitlicher Differentialquotient gegen Null geht, wenn sich die Bodensteifigkeit unter der Einwirkung der Bodenverdichtungmaschine ebenfalls nicht mehr ändert, ohne daß es hierbei auf den tatsächlichen Wert der erreichten Bodensteifigkeit ankäme. Es ist daher mit einfachen technischen Hilfsmitteln, ggf. unter Einschluß einer optischen oder akustischen Anzeige, möglich, festzustellen und anzuzeigen, wann die bei dem vorliegenden Verdichtungsmaterial, der verwendeten Verdichtungsmaschine, der gegebenen Feuchtigkeit im Boden usw. maximal mögliche Verdichtungsgrad erreicht worden ist, so daß die weitere Bearbeitung des Bodens mit der Bodenverdichtungsmaschine eingestellt werden kann, weil damit keine weitere Verdichtung des Bodens mehr erreichbar ist sondern im Gegenteil beim Weiterarbeiten , wie bekannt , nur die Gefahr einer Wiederauflockerung des Bodens besteht.In the method according to the invention, compared to the known method, instead of the actual value of the soil strength expressed in the measured acceleration, only the relative temporal change in the degree of compaction is determined, for which the engine power can be used as machine parameters, since tests by the applicant have shown that the the drive motor for the vibration exciter required power decreases with increasing ground stiffness and their temporal differential quotient goes to zero if the ground stiffness also no longer changes under the influence of the soil compaction machine, without it being a matter of the actual value of the ground stiffness achieved. It is therefore possible with simple technical aids, possibly including an optical or acoustic display, to determine and indicate when the maximum possible degree of compaction has been reached with the compaction material used, the compaction machine used, the moisture level in the soil, etc., so that the further cultivation of the soil can be stopped with the soil compaction machine, because this means that no further compaction of the soil is achievable, but on the contrary, as is known, there is only the risk of loosening the soil when continuing to work.
Für die Feststellung der Motorleistung bietet der Motor verschiedene, einfach zu messende Parameter an, zu denen das abgegebene Motor- oder Motorgetriebe-Drehmoment , die Abgastemperatur und der aktuelle Kraftstoffverbrauch gehören. Die Veränderung der gemessenen Parameter kann direkt z.B. als sich mit abnehmender Geschwindigkeit ändernder Zeigerausschlag , angezeigt werden, um dann vom Bedienenden ausgewertet zu werden. Bei einer anderen bevorzugten Ausführungsform der Erfindung ist vorgesehen, ein - optisches, akustisches oder dgl. - Signal zu erzeugen, wenn der zeitliche Differentialquotient der Motorleistung bzw. des für diese charakteristischen Motorparameterseinen vorgegebenen Wert unterschreitet. In jedem Falle genügen baulich einfache, kostengünstige, störsichere und verschleißarme Hilfsmittel , um dies zu bewerkstelligen.To determine the engine performance, the engine offers various, easy-to-measure parameters, including the delivered engine or engine transmission torque, the exhaust gas temperature and the current fuel consumption. The change in the measured parameters can be displayed directly, for example as a pointer deflection that changes with decreasing speed, in order then to be evaluated by the operator. In another preferred embodiment of the invention, it is provided to generate an - optical, acoustic or the like - signal when the temporal differential quotient of the engine power or the engine parameter characteristic for this falls below a predetermined value. In any case, structurally simple, inexpensive, fail-safe and low-wear aids are sufficient to accomplish this.
Die Hilfsmittel als solche, die zur Realisierung des erfindungsgemäßen Verfahrens erforderlich sind, sind dem Fachmann geläufig und größtenteils komplett im Handel erhältlich, wie z.B. im Falle der Abgastemperaturmessung.The auxiliaries as such, which are required to implement the method according to the invention, are familiar to the person skilled in the art and for the most part are completely commercially available, such as in the case of exhaust gas temperature measurement.
Wegen des nur geringen Aufwandes, der zur Durchführung des erfindungsgemäßen Verfahrens bei Bodenverdichtungsmaschinen getrieben werden muß, eignet sich dieses insbesondere auch für Bodenverdichtungsgeräte von mittlerer und kleiner Größe, beispielsweise speziell auch für Vibrationsplatten. Andererseits ist die Anwendungsmöglichkeit natürlich auch bei Großmaschinen gegeben, sofern es auch bei diesen nur darum geht, festzustellen, wann der maximal erreichbare Verdichtungsgrad im wesentlichen erreicht worden ist.Because of the low effort that has to be carried out to carry out the method according to the invention in soil compaction machines, this is particularly suitable for soil compaction devices of medium and small size, for example especially also for vibratory plates. On the other hand, the application is of course also available for large machines, provided that it is only a question of determining when the maximum achievable degree of compaction has essentially been reached.
