Abstract
Description
Die Erfindung betrifft eine Baumaschine mit Schnellkupplung zum Ankuppeln eines Werkzeuges an einen Ausleger nach dem Oberbegriff des Anspruchs 1.The invention relates to a construction machine with quick coupling for coupling a tool to a boom according to the preamble of claim 1.
Es sind bereits Baumaschinen mit Schnellkupplung zum Ankuppeln eines Werkzeuges an einen Ausleger bekannt. So weist beispielsweise die
Die Baumaschinen, beispielsweise Hydraulikbagger, werden mit sehr unterschiedlichen Werkzeugen bestückt, beispielsweise mit Tieflöffeln, Schaufeln, Greifern, Hämmern, Scheren, Fräsen, Reißzähnen, Lasthaken und vieles mehr. Neben dem vorgenannten Hydraulikbagger sind aber auch Radlader und andere Baumaschinen, die entsprechende Ausleger aufweisen, einsetzbar. Neben ihrer typischen Verwendung sind diese Baumaschinen durch den Anbau von verschiedenen Werkzeugen zu Multifunktionsmaschinen geworden.The construction machinery, such as hydraulic excavators, are equipped with very different tools, such as with buckets, shovels, grippers, hammers, shears, milling, fangs, hooks and much more. In addition to the aforementioned hydraulic excavator but also wheel loaders and other construction machinery, which have corresponding boom, can be used. In addition to their typical These construction machines have become multifunctional machines by the use of different tools.
Durch die Verwendung von Werkzeugschnellwechslern und der Möglichkeit, gleichzeitig mit dem Ankupplungsvorgang auch die notwendige Energieversorgung elektrischer oder hydraulischer Art herzustellen, ist das Aufnehmen verschiedener Werkzeuge grundsätzlich wesentlich erleichtert worden. Dieser erleichterte Anbau führt aber zu dem Problem, daß von dem Bedienpersonal der Baumaschine eventuell auftretende technische und sicherheitstechnische Probleme nicht erfasst werden. So kann ein technisches Problem beispielsweise darin bestehen, daß beim Anbau eines hydraulisch angetriebenen Werkzeugs der hydraulische Druck der baumaschinenseitigen Hydraulikeinrichtung, die Fördermenge oder auch das eingesetzte Öl zu dem angebauten Werkzeug nicht passen. Dies kann einerseits zur Funktionsuntüchtigkeit, andererseits aber auch bis hin zur Zerstörung des Werkzeugs führen. Sicherheitstechnische Probleme ergeben sich beispielsweise durch den Anbau eines zu großen oder zu schweren Löffels, da hier die Standsicherheit der Baumaschine beim Lastheben nicht mehr gewährleistet ist.Through the use of quick tool changers and the possibility of producing the necessary energy supply of electrical or hydraulic type simultaneously with the coupling process, it has basically been made much easier to pick up different tools. However, this facilitated cultivation leads to the problem that may be detected by the operating personnel of the construction machine possibly occurring technical and safety problems. Thus, a technical problem, for example, consist in the fact that do not fit when attaching a hydraulically driven tool, the hydraulic pressure of the construction-side hydraulic device, the flow or the oil used to the attached tool. On the one hand, this can lead to inoperability, but on the other hand, even to the destruction of the tool. Safety problems arise, for example, by the cultivation of a too large or too heavy spoon, since the stability of the construction machine when lifting the load is no longer guaranteed.
Im weiteren kann durch die Übermittlung der Kinematikdaten eine Kollision z.B. mit der Kabine oder auch Oberleitungen etc. verhindert werden.Furthermore, the transmission of the kinematics data may cause a collision, e.g. be prevented with the cabin or overhead lines, etc.
Aus der
Aufgabe der Erfindung ist es daher, eine Baumaschine mit Schnellkupplung derart weiterzubilden, daß technische bzw. sicherheitstechnische Risiken beim automatischen Ankuppeln eines Werkzeuges an eine Baumaschine sicher verhindert werden sowie die Funktion einwandfrei gewährleistet ist.The object of the invention is therefore to develop a construction machine with quick coupling such that technical or safety risks in automatic Coupling a tool to a construction machine safely prevented and the function is properly guaranteed.
Erfindungsgemäß wird diese Aufgabe ausgehend von einer gattungsgemäßen Baumaschine mit Schnellkupplung durch die Kombination der Merkmale des Anspruchs 1 gelöst. Demnach ist ein Identifizierungssystem vorgesehen, das einerseits werkzeugseitig als Mittel zur Identifizierung der Art, Größe, des Gewichts und der Abmessung, des Werkzeugs einen Transponder sowie baumaschinenseitig ein Mittel zum Auslesen und Verarbeiten der werkzeugbezogenen Informationen beinhaltet.This object is achieved on the basis of a generic construction machine with quick coupling by combining the features of claim 1. Accordingly, an identification system is provided which includes on the one hand on the tool side as means for identifying the type, size, weight and dimension, the tool a transponder and the construction machine side means for reading and processing the tool-related information.
Mit diesem erfindungsgemäßen Identifizierungssystem kann im ersten Schritt beim Anbau des Werkzeuges der Baumaschine über das entsprechende Identifizierungssystem mitgeteilt werden, welches Werkzeug angebaut wurde, d. h. welches Gewicht und welchen Inhalt der gegebenenfalls angebaute Tieflöffel hat, welche Ölmenge und welchen Öldruck das Werkzeug zum Betrieb benötigt bzw. welche Abmessungen das Werkzeug hat.With this identification system according to the invention can be communicated in the first step in the cultivation of the tool of the construction machine on the corresponding identification system, which tool was grown, d. H. what weight and what content of the possibly attached backhoe, what oil quantity and which oil pressure the tool needs to operate or what dimensions the tool has.
In einem zweiten Schritt werden dann dem Bordrechner die Daten übermittelt, die dieser dann beispielsweise an die Hydraulikpumpe zum Einstellen der richtigen Menge und des Drucks des Hydrauliköls zur Verfügung stellt. Aus den übermittelten Gewichten und Abmessungen kann die zur Verfügung stehende Nutzlast ermittelt und angezeigt werden. Weiterhin können die mögliche Reichweite, Grabtiefe und Höhe angezeigt werden bzw. als Grenzwerte in die Steuerung des Auslegers eingespeist werden.In a second step, the data is transmitted to the on-board computer, which then makes it available, for example, to the hydraulic pump for setting the correct amount and the pressure of the hydraulic oil. From the transmitted weights and dimensions, the available payload can be determined and displayed. Furthermore, the possible range, digging depth and height can be displayed or fed as limit values into the control of the boom.
Der Transponder wirkt mit den baumaschinenseitigen Mitteln zum Auslesen und Verarbeiten der Informationen zusammen. Diese sind vorzugsweise Teil des Bordrechners oder sie sind zumindest mit diesem verbunden.The transponder interacts with the construction-machine-side means for reading and processing the information. These are preferably part of the on-board computer or they are at least connected to this.

In Fig. 1 ist als Baumaschine beispielhaft ein Hydraulikbagger 10 dargestellt, an dessen Ausleger 12 ein Werkzeugwechsler 14 mit Energiedurchführung angebaut ist. Dieser als Schnellwechsler ausgeführte Werkzeugwechsler 14 kann ein beliebiges Werkzeug 16 automatisch aufnehmen, wobei bei Aufnahme des Werkzeuges 16 gleichzeitig der Energiekreis, beispielsweise im vorliegenden Beispiel der Hydraulikkreis, angekuppelt wird.In Fig. 1 as a construction machine by way of example a
Gemäß der vergrößert dargestellten Ausgestaltung des Auslegers 12 mit Schnellkupplung 14 und Werkzeug 16 ist in Fig. 2a bzw. 2b ein an einem Hydraulikbaggerausleger angebauter Löffel 16 gezeigt. Dieser Löffel 16 weist ein werkzeugseitiges Mittel 18 zur Identifizierung der Art und Größe des Werkzeugs in Form eines Transponders auf. Dieser Transponder 18 teilt beim Anbau des Löffels 16 dem hier nicht näher dargestellten Bordrechner des Hydraulikbaggers 10 mit, wie hoch das Gewicht des Löffels ist und welchen Inhalt dieser hat. Weiterhin werden die Abmessungen des Löffels 16 an den Bordrechner weitergegeben. In einem hier ebenfalls nicht näher dargestellten Speicher des Bordrechners sind die zu dem angebauten Löffel notwendigen Ölmengen bzw. Druckverhältnisse für den Hydraulikkreis abgelegt. Nach Einlesen des Typs des Löffels 16 werden diese Daten dann vom Bordrechner bereitgestellt, so daß die Hydraulikpumpe auf die richtige Ölmenge und den richtigen Öldruck eingestellt werden kann. Weiterhin kann gleichzeitig die Nutzlast und die mögliche Reichweite bzw. Grabtiefe und Höhe des Baggerauslegers bestimmt werden. Gleichzeitig können entsprechende Grenzwerte in einer Sicherheitssteuerung erzeugt werden, die eine Fehlbedienung des Hydraulikbaggers sicher verhindert. Derartige Sicherheitssteuerungen sind bei bekannten Hydraulikbaggern bereits vorgesehen und brauchen an dieser Stelle nicht weiter erläutert werden. Sie verhindern z.B., daß die Baumaschine aufgrund eines zu weit ausladenden schweren Löffels in eine instabile Lage versetzt wird.According to the embodiment of the
