Description
Die Erfindung bezieht sich auf ein Verfahren gemäß dem Ober begriff des Patentanspruchs 1.The invention relates to a method according to the Ober Concept of claim 1.
Bei den bekannten Verfahren wird zum Feststellen des Endzu standes der im Boden erreichten Verdichtung als Maschinen parameter die für die Verdichtungsarbeit maßgebliche Be schleunigung 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 gewünsch te Verdichtungszustand erreicht ist.In the known methods, the end is determined level of compaction achieved in the soil as machines parameters the decisive for the compaction work acceleration of the compression element, in the known case the vibrating rollers of a soil compaction roller, with Measured with the help of accelerometers. The measured Acceleration corresponds to the actual value of the respectively achieved Soil strength and shows the operator when the desired te compression state is 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 ver nünftig ist.The necessary to carry out the known method Accelerometers form together with the associated Evaluation electronics a very complex and cost-intensive Facility whose use is therefore only ver is reasonable.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren nach dem Oberbegriff des Patentanspruchs 1 zu schaffen, das mit wesentlich einfacheren und kostengünstigeren Mitteln rea lisiert werden kann als das bekannte Verfahren und sich da her auch für die Anwendung bei kleinen Geräten wie Boden verdichtungsplatten, Stampfern, oder dgl. eignet.The invention is based on the object of a method the preamble of claim 1 to create the much simpler and cheaper means rea can be lized as the known method and there also for use with small devices such as floors compression plates, rammers, or the like.
Die vorstehende Aufgabe wird durch die im Kennzeichnungs teil des Patentanspruchs 1 genannten Merkmale gelöst.The above task is accomplished by the in labeling Part of claim 1 mentioned features solved.
Bei dem erfindungsgemäßen Verfahren wird gegenüber dem be kannten Verfahren anstelle der in der gemessenen Beschleu nigung zum Ausdruck kommenden Ist-Wertes der Bodenfestig keit nur die relative zeitliche Veränderung des Verdich tungsgrades 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 Differential quotient gegen Null geht, wenn sich die Bodensteifigkeit unter der Einwirkung der Bodenverdichtungsmaschine 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, festzu stellen und anzuzeigen, wann die bei dem vorliegenden Ver dichtungsmaterial, der verwendeten Verdichtungsmaschine, der gegebenen Feuchtigkeit im Boden usw. maximal mögliche Verdichtungsgrad erreicht worden ist, so daß die weitere Be arbeitung des Bodens mit der Bodenverdichtungsmaschine ein gestellt werden kann, weil damit keine weitere Verdichtung des Bodens mehr erreichbar ist sondern im Gegenteil beim Weiterarbeiten , wie bekannt , nur die Gefahr einer Wieder auflockerung des Bodens besteht.In the method according to the invention compared to the be known procedures instead of those in the measured accelerator the actual value of the floor strength only the relative change in the compression over time degree of determination, for which the machine parameters Engine power can be used because attempts of Applicant have shown that the drive motor for the Vibration exciter demanded performance with increasing Soil stiffness decreases and their temporal differential quotient goes to zero when the floor stiffness under the influence of the soil compaction machine too no longer changes without the actual The value of the soil rigidity achieved would matter. It is therefore with simple technical aids, possibly including an optical or acoustic display, possible to fix ask and indicate when the in this Ver sealing material, the used compression machine, the given moisture in the soil etc. maximum possible Degree of compaction has been reached, so that the further loading working the soil with the soil compaction machine can be put because there is no further compression of the ground is more accessible but on the contrary with Continuing to work, as is known, only involves the risk of re-starting loosening of the soil exists.
Für die Feststellung der Motorleistung bietet der Motor ver schiedene, einfach zu messende Parameter an, zu denen das abgegebene Motor- oder Motorgetriebe-Drehmoment , die Ab gastemperatur und der aktuelle Kraftstoffverbrauch gehören. Die Veränderung der gemessenen Parameter kann direkt z.B. als sich mit abnehmender Geschwindigkeit ändernder Zeiger ausschlag , angezeigt werden, um dann vom Bedienenden aus gewertet zu werden. Bei einer anderen bevorzugten Ausfüh rungsform der Erfindung ist vorgesehen, ein - optisches, akustisches oder dgl. - Signal zu erzeugen, wenn der zeit liche Differentialquotient der Motorleistung bzw. des für diese charakteristischen Motorparameter seinen vorgegebenen Wert unterschreitet. In jedem Falle genügen baulich ein fache, kostengünstige, störsichere und verschleißarme Hilfs mittel , um dies zu bewerkstelligen.The engine offers ver for determining the engine power different, easy-to-measure parameters, for which the delivered engine or engine transmission torque, the Ab gas temperature and current fuel consumption. The change in the measured parameters can be e.g. as a pointer changing with decreasing speed rash, are displayed, then from the operator to be rated. In another preferred embodiment tion form of the invention is provided, an - optical, acoustic or the like - signal to generate when the time Differential quotient of the engine power or for this characteristic engine parameters its given Falls below value. In any case, construction is sufficient fold, inexpensive, interference-free and low-wear auxiliary medium to do this.
Die Hilfsmittel als solche, die zur Realisierung des er findungsgemäßen Verfahrens erforderlich sind, sind dem Fach mann geläufig und größtenteils komplett im Handel erhält lich, wie z.B. im Falle der Abgastemperaturmessung.The tools as such, which are used to realize the he inventive method are required are the subject man is familiar and for the most part completely available in stores 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. Anderer seits ist die Anwendungsmöglichkeit natürlich auch bei Groß maschinen gegeben, sofern es auch bei diesen nur darum geht, festzustellen, wann der maximal erreichbare Verdichtungs grad im wesentlichen erreicht worden ist.Because of the minimal effort required to implement the Method according to the invention in soil compaction machines must be driven, this is particularly suitable for medium-sized and small-sized soil compactors, for example, especially for vibration plates. Other on the other hand, the application is of course also for large machines, provided that these are also only about determine when the maximum achievable compaction degree has essentially been achieved.
