Description

Die vorliegende Erfindung betrifft eine Baumaschine mit einer Arbeitsausrüstung, das wenigstens ein Schwenklager und Hydraulikleitungen aufweist, wobei Hydraulikleitungen durch das Schwenklager verlaufen.The present invention relates to a construction machine having work equipment comprising at least one pivot bearing and hydraulic lines, hydraulic lines passing through the pivot bearing.

Baumaschinen wie Bagger, Lader oder Krane weisen Arbeitsausrüstungen auf, die ihrem Anwendungsbereich entsprechend als Bagger-, Lader- oder Kranarme ausgebildet sind. Sie weisen dabei verschiedene Teilabschnitte auf, die relativ zueinander beweglich angeordnet sind.Construction equipment such as excavators, loaders or cranes have work equipment that are designed according to their scope as excavator, loader or crane arms. They have different sections, which are arranged movable relative to each other.

Ein Baggerarm umfasst ein Anbaugerät wie beispielsweise eine Schaufel und einen oder mehrere Teilabschnitte, die über Gelenke oder Schwenklager drehbar relativ zueinander gelagert sind. Die Bewegung der einzelnen Teilabschnitte der Arbeitsausrüstungen erfolgt hierbei üblicherweise mittels hydraulischer Zylinder, die entsprechend mit den Teilabschnitten der Arbeitsausrüstung verbunden sind. Es sind jedoch genauso Vorrichtungen denkbar, bei denen andere als hydraulische Antriebe zum Bewegen der Arbeitsausrüstung bzw. dessen Teilabschnitten genutzt werden.An excavator arm includes an attachment such as a bucket and one or more sections that are rotatably supported by joints or pivot bearings relative to each other. The movement of the individual sections of the work equipment here is usually carried out by means of hydraulic cylinders, which are respectively connected to the sections of the work equipment. However, devices are equally conceivable in which other than hydraulic drives for moving the work equipment or its subsections are used.

Beim Betrieb der Arbeitsausrüstung sind Ausführungen mit einem oder mehreren Hydraulikzylindern und entsprechend unterschiedlichen Mengen an Hydraulikleitungen denkbar. Der Einfachheit halber kann im Folgenden von einem Hydraulikzylinder und einer Hydraulikleitung die Rede sein, was aber stets eine Ausführung mit mehr als einem Hydraulikzylinder und einer entsprechenden Mehrzahl an Hydraulikleitungen einschließt. Ebenso kann im Folgenden von einem Schwenklager die Rede sein, was aber ebenfalls stets eine Ausführung mit mehr als einem Schwenklager einschließt.When operating the work equipment versions with one or more hydraulic cylinders and correspondingly different amounts of hydraulic lines are conceivable. For the sake of simplicity, a hydraulic cylinder and a hydraulic line may be mentioned below, but this always includes an embodiment with more than one hydraulic cylinder and a corresponding plurality of hydraulic lines. Likewise, in the following of a pivot bearing be discussed, but also always includes an embodiment with more than one pivot bearing.

Zum Betrieb des Hydraulikzylinders ist eine Versorgung mit einem Druckmedium erforderlich, welche üblicherweise über Hydraulikleitungen erfolgt, die den Hydraulikzylinder mit einer Hydraulikölquelle verbinden. Diese Hydraulikölquelle befindet sich üblicherweise nicht an der Arbeitsausrüstung selbst, sondern ist vielmehr im Bereich der Baumaschine angeordnet, welche die Arbeitsausrüstung aufweist.For the operation of the hydraulic cylinder, a supply of a pressure medium is required, which usually takes place via hydraulic lines which connect the hydraulic cylinder with a hydraulic oil source. This hydraulic oil source is usually not located on the work equipment itself, but rather is located in the area of the construction machine, which has the work equipment.

Es ist somit erforderlich, eine hydraulische Verbindung zwischen der Hydraulikölquelle an der Baumaschine einerseits und dem Hydraulikzylinder an der Arbeitsausrüstung andererseits bereitzustellen, wobei die hydraulische Verbindung gegebenenfalls bis hin zu einem Endbereich der Arbeitsausrüstung führt, in welcher sich im Falle eines Baggers ein durch einen Hydraulikzylinder beweglich gelagertes Anbaugerät wie eine Baggerschaufel befindet. Da somit die Hydraulikleitung zwischen Teilabschnitten der Arbeitsausrüstung verläuft, die relativ zueinander drehbar sind, erfährt die Hydraulikleitung, die auch im Bereich des Schwenklagers der Arbeitsausrüstung ohne Trennung verläuft, aufgrund der Drehbewegungen der Arbeitsausrüstung eine besondere Biege- und Torsionsbeanspruchung. Um die Längenänderungen aufgrund der Drehbewegungen dabei zu minimieren, wird eine Verlegung der Hydraulikleitungen im Bereich des Drehpunkts oder Drehmittelpunkts angestrebt, wobei die Hydraulikleitungen dabei zum Zwecke einer möglichst kompakten Bereitstellung mit geeigneten Vorrichtungen zusammengehalten werden können. Durch diese Beanspruchungen und Relativbewegungen der Hydraulikleitungen in den Drehmittelpunkten können Schlauchbeschädigungen verursacht oder beschleunigt werden, was zu einem Defekt der Hydraulikanlage führen kann. Besonders problematisch ist dabei, dass die undefinierten Biege- und Torsionsbeanspruchungen eine unkontrollierte Überlagerung verschiedener Beanspruchungen darstellen, welche sich besonders nachteilig auf die Lebensdauer der hydraulischen Leitungen auswirken können.It is thus necessary to provide a hydraulic connection between the hydraulic oil source on the construction machine on the one hand and the hydraulic cylinder on the working equipment on the other hand, the hydraulic connection possibly leading to an end portion of the working equipment in which in the case of an excavator a movable by a hydraulic cylinder mounted attachment such as an excavator bucket is located. Thus, since the hydraulic line passes between sections of the work equipment which are rotatable relative to each other, the hydraulic line, which also runs in the region of the pivot bearing of the work equipment without separation, undergoes a special bending and torsional stress due to the rotational movements of the work equipment. In order to minimize the length changes due to the rotational movements thereby, a laying of the hydraulic lines in the region of the fulcrum or center of rotation is sought, the hydraulic lines can be held together for the purpose of the most compact possible provision with suitable devices. These stresses and relative movements of the hydraulic lines in the centers of rotation hose damage can be caused or accelerated, which can lead to a defect of the hydraulic system. A particular problem is that the undefined bending and torsional stresses represent an uncontrolled superposition of different stresses, which can have a particularly detrimental effect on the life of the hydraulic lines.

Aufgabe der vorliegenden Erfindung ist es daher, eine erfindungsgemäße Baumaschine mit entsprechenden Hydraulikleitungen vorteilhaft weiterzubilden, so dass die Ausfallwahrscheinlichkeit der Hydraulikleitungen gesenkt wird.Object of the present invention is therefore to develop a construction machine according to the invention advantageously with corresponding hydraulic lines, so that the probability of failure of the hydraulic lines is lowered.

Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst, wonach eine Baumaschine, wie ein Bagger, Lader oder Kran vorgesehen ist, mit wenigstens einer hydraulischen Arbeitsausrüstung, wie einem Bagger-, Lader- oder Kranarm, wobei die Arbeitsausrüstung wenigstens ein Schwenklager umfasst, mit wenigstens einer am Schwenklager vorgesehenen Trennplatte, wenigstens einer ersten Hydraulikleitung und wenigstens einer zweiten Hydraulikleitung, wobei die wenigstens eine Trennplatte mit dem wenigstens einem Schwenklager und den Hydraulikleitungen verbunden oder verbindbar ist.This object is achieved by a device with the features of claim 1, according to which a construction machine, such as an excavator, loader or crane is provided with at least one hydraulic work equipment, such as a digger, loader or crane arm, the work equipment at least one Swivel bearing comprises, with at least one partition plate provided on the pivot bearing, at least one first hydraulic line and at least one second hydraulic line, wherein the at least one partition plate is connected or connectable to the at least one pivot bearing and the hydraulic lines.

Durch das Einbringen einer Trennstelle in Form der Trennplatte, welche eine beliebig im Raum angebrachte oder anbringbare Verbindungs- bzw. Verschraubungsmöglichkeit hydraulischer Komponenten darstellt, wird erreicht, dass jede hydraulische Komponente vorteilhafterweise genau eine Beanspruchungsart aufgrund einer Drehbewegung der Arbeitsausrüstung erfährt. Eine Überlagerung verschiedener oder mehrerer Beanspruchungen wird durch die Trennstelle ausgeschlossen, da hydraulische Komponenten, welche sich an einer ersten Seite der Trennplatte befinden, nur durch Bewegungen der Arbeitsausrüstung beeinflusst werden, die ebenfalls an der ersten Seite der Trennplatte stattfinden. Umgekehrt beeinflussen Bewegungen der Arbeitsausrüstung, die an einer zweiten Seite der Trennplatte stattfinden nicht die hydraulischen Komponenten, die sich an der ersten Seite der Trennplatten befinden, sondern nur diejenigen, die sich an der zweiten Seite der Trennplatte befinden. Jede hydraulische Komponente erfährt nur noch eine definierte Beanspruchung und auf weitere Befestigungspunkte oder Halterungen der hydraulischen Komponenten kann verzichtet werden. Durch die von der Trennstelle vorgegebene Anordnung der hydraulischen Komponenten wird es ermöglicht, dass die Biegeradien der Hydraulikschläuche vergrößert und somit deren Ausfallwahrscheinlichkeit gesenkt wird.By introducing a separation point in the form of the partition plate, which represents an arbitrarily mounted in space or attachable connection or screwing possibility of hydraulic components, it is achieved that each hydraulic component advantageously undergoes exactly one type of stress due to a rotational movement of the working equipment. Overlapping of several or more stresses is precluded by the separation point because hydraulic components located on a first side of the separation plate are only affected by movements of the work equipment that also take place on the first side of the separation plate. Conversely, movements of the work equipment that take place on a second side of the divider plate do not affect the hydraulic components located on the first side of the divider Separation plates are located, but only those that are located on the second side of the partition plate. Each hydraulic component undergoes only a defined load and further attachment points or brackets of the hydraulic components can be dispensed with. The predetermined by the separation point arrangement of the hydraulic components, it is possible that the bending radii of the hydraulic hoses increases and thus their probability of failure is lowered.

Ein weiterer Vorteil besteht darin, dass die Erstmontage bei der Herstellung einer erfindungsgemäßen Baumaschine durch die klaren, definierten und einfachen Trennplatten erleichtert und beschleunigt wird. Ein ähnlicher Vorteil liegt darin, dass die klar definierten Trennstellen und die durch diese vereinfachte Konstruktion des erfindungsgemäßen Schwenklagers zu einer Zeitersparnis beim Auswechseln von Hydraulikleitungen führt, wodurch die Ausfallzeiten des Gerätes im Reparaturfall reduziert werden.Another advantage is that the initial assembly in the manufacture of a construction machine according to the invention is facilitated and accelerated by the clear, defined and simple separation plates. A similar advantage is that the clearly defined separation points and simplified by this construction of the pivot bearing according to the invention leads to a time savings in the replacement of hydraulic lines, whereby the downtime of the device can be reduced in case of repair.

In einem bevorzugten Ausführungsbeispiel ist vorgesehen, dass die wenigstens eine Trennplatte wenigstens einen Verbindungsabschnitt umfasst, an den die wenigstens zwei Hydraulikleitungen miteinander und/oder mit der wenigstens einen Trennplatte verbunden oder verbindbar sind.In a preferred embodiment it is provided that the at least one partition plate comprises at least one connecting portion, to which the at least two hydraulic lines are connected or connectable to each other and / or to the at least one partition plate.

Im einfachsten Falle kann dabei eine der Hydraulikleitungen durch eine Durchführung in der Trennplatte hindurchgeführt werden, wobei die Durchführung selbst den Verbindungsabschnitt der Trennplatte darstellt. Eine zweite Hydraulikleitung kann an die erste Hydraulikleitung angeschlossen und mit dieser fest verbunden sein. Auf diese Weise können die an Hydraulikleitungen üblicherweise bereits vorhandenen Gewindegeometrien zum Befestigen der Hydraulikleitungen an die Trennplatte herangezogen werden, so dass keine zusätzlichen Vorrichtungen hierfür bereitgestellt werden müssen.In the simplest case, one of the hydraulic lines can be passed through a passage in the partition plate, wherein the implementation itself represents the connecting portion of the partition plate. A second hydraulic line may be connected to the first hydraulic line and fixedly connected thereto. In this way, the already existing on hydraulic lines thread geometries can be used to attach the hydraulic lines to the partition plate, so that no additional devices have to be provided for this purpose.

In einem weiteren bevorzugten Ausführungsbeispiel ist denkbar, dass die wenigstens zwei Hydraulikleitungen miteinander und/oder mit der wenigstens einen Trennplatte und/oder mit dem wenigstens einen Schwenklager form- und/oder kraft- und/oder stoffschlüssig verbunden oder verbindbar sind.In a further preferred embodiment, it is conceivable that the at least two hydraulic lines with each other and / or with the at least one Separating plate and / or with the at least one pivot bearing positively and / or non-positively and / or materially connected or connectable.

Eine derartige Anbindung der unterschiedlichen Bestandteile der Arbeitsausrüstung ermöglicht vorteilhafterweise zum einen die verlustfreie Übertragung von druckbeaufschlagter Hydraulikflüssigkeit zwischen den beiden Hydraulikleitungen und zum anderen erfolgt dadurch eine Stabilisierung der Hydraulikleitungen in Bezug auf Kräfte, welche auf die Hydraulikleitungen aufgrund der Bewegung der Arbeitsausrüstung einwirken. Im Gegensatz zu einer durchgehenden Hydraulikleitung, welche von keiner Trennplatte getrennt und deshalb nicht durch Anbindung an das Schwenklager mittels der Trennplatte stabilisiert ist, werden in der vorliegenden Erfindung Biege- und Torsionskräfte nicht von einer Hydraulikleitung in die andere übertragen, beziehungsweise von einem ersten Abschnitt einer Hydraulikleitung in einen zweiten Abschnitt einer Hydraulikleitung. Vielmehr werden die entsprechenden Biege- und Torsionskräfte mittels der Trennplatte in das Schwenklager eingeleitet. Eine Beeinflussung der Hydraulikleitungen wird so vermieden, Übertragungen von Bewegungen von einer Hydraulikleitung auf die andere, beziehungsweise von einem ersten Abschnitt einer Hydraulikleitung in einen zweiten Abschnitt einer Hydraulikleitung, welche zu erhöhten Abnutzungserscheinungen führen können, unterbleiben.Such a connection of the different components of the work equipment advantageously allows, on the one hand, lossless transfer of pressurized hydraulic fluid between the two hydraulic lines and, on the other hand, a stabilization of the hydraulic lines with respect to forces acting on the hydraulic lines due to the movement of the work equipment. In contrast to a continuous hydraulic line, which is not separated from any partition plate and therefore not stabilized by connection to the pivot bearing by means of the partition plate, in the present invention, bending and torsional forces are not transmitted from one hydraulic line to the other, or from a first portion of a Hydraulic line in a second section of a hydraulic line. Rather, the corresponding bending and torsional forces are introduced by means of the partition plate in the pivot bearing. Influencing the hydraulic lines is thus avoided, transfers of movements from one hydraulic line to the other, or from a first section of a hydraulic line into a second section of a hydraulic line, which can lead to increased signs of wear, to be omitted.

In einer weiterhin bevorzugten Ausführungsform ist es denkbar, dass die wenigstens zwei Hydraulikleitungen im Bereich der wenigstens einen Trennplatte relativ zueinander und/oder relativ zum wenigstens einen Schwenklager mittels der wenigstens einen Trennplatte fixiert oder fixierbar sind.In a further preferred embodiment, it is conceivable that the at least two hydraulic lines are fixed or fixable in the region of the at least one partition plate relative to one another and / or relative to the at least one pivot bearing by means of the at least one partition plate.

Ein solches erfindungsgemäßes Fixieren der Hydraulikleitungen relativ zueinander bzw. relativ zu den weiteren Bestandteilen der Arbeitsausrüstung erlaubt es vorteilhafterweise, die Hydraulikleitungen während des Bewegens der Arbeitsausrüstungunabhängig voneinander mit Biege- und Torsionskräften zu beaufschlagen. Kräfte, die in eine Hydraulikleitung von einer Seite des Schwenklagers eingeleitet werden, werden von der Trennplatte aufgenommen und in das Schwenklager eingeleitet. Die Kräfte werden nicht in die zweite Hydraulikleitung übertragen, so dass es dort zu keiner nachteiligen Überlagerung von die Abnutzung der Hydraulikleitungen fördernden Kräften kommt.Such an inventive fixing of the hydraulic lines relative to each other or relative to the other components of the work equipment advantageously allows to pressurize the hydraulic lines during movement of the working equipment independently of each other with bending and torsional forces. Forces, which are introduced into a hydraulic line from one side of the pivot bearing, are absorbed by the partition plate and introduced into the pivot bearing. The forces are not transmitted to the second hydraulic line, so that there is no adverse superposition of the wear of the hydraulic lines promoting forces.

In einem weiteren bevorzugten Ausführungsbeispiel ist eine Baumaschine denkbar, in der die wenigstens zwei Hydraulikleitungen über wenigstens einen Verschraubungsabschnitt mit der wenigstens einen Trennplatte und/oder miteinander verbunden oder verbindbar sind und dass die wenigstens zwei Hydraulikleitungen relativ zueinander und/oder relativ zur wenigstens einen Trennplatte und/oder relativ zum wenigstens einen Schwenklager mittels des wenigstens einen Verschraubungsabschnitts fixiert oder fixierbar sind.In a further preferred embodiment, a construction machine is conceivable in which the at least two hydraulic lines via at least one Verschraubungsabschnitt with the at least one partition plate and / or interconnected or connectable and that the at least two hydraulic lines relative to each other and / or relative to at least one partition plate and / or are fixed or fixable relative to the at least one pivot bearing by means of the at least one screwing section.

In diesem Ausführungsbeispiel werden die üblicherweise an Hydraulikleitungen bereitgestellten Verschraubungsabschnitte vorteilhaft dazu benutzt, die Anbindung zwischen Hydraulikleitungen, Trennplatte und Schwenklager zu ermöglichen. Es kann somit auf Standardteile zurückgegriffen werden und es sind keine gesonderten Vorrichtungen nötig um die erfindungsgemäße Anbindung zu verwirklichen.In this embodiment, the Verschraubungsabschnitte usually provided on hydraulic lines are advantageously used to allow the connection between the hydraulic lines, partition plate and pivot bearings. It can thus be used on standard parts and there are no separate devices necessary to realize the inventive connection.

In einem weiteren bevorzugten Ausführungsbeispiel ist es denkbar, dass die wenigstens eine Trennplatte wenigstens eine einstückig ausgeführte Positionierungsplatte umfasst, welche wenigstens den einen Verbindungsabschnitt aufweist und mit mindestens der Hälfte der Hydraulikleitungen unmittelbar verbunden oder verbindbar ist.In a further preferred embodiment, it is conceivable that the at least one partition plate comprises at least one integrally formed positioning plate, which has at least one connecting portion and is directly connected or connectable with at least half of the hydraulic lines.

Dieses einstückige Ausführungsbeispiel ist besonders dann vorteilhaft, wenn mehr als zwei Hydraulikleitungen durch das Schwenklager über die Trennplatte geführt werden sollen. Es ermöglicht nämlich auf konstruktiver Seite von vornherein festzulegen, welche Geometrie die Hydraulikleitungen zueinander und zum Schwenklager einnehmen sollen. Da die Trennplatte, beziehungsweise deren Positionierungsplatte einstückig vorliegt, gibt sie durch ihre Geometrie während der Montage eindeutig vor, wie die Hydraulikleitungen im Einklang mit den konstruktiven Vorgaben zu montieren sind. Ist nämlich einmal der wenigstens eine Verbindungsabschnitt konstruktionsbedingt auf der Trennplatte bzw. auf deren einstückig ausgeführter Positionierungsplatte vorgegeben, so kann während des Montageprozesses nicht mehr ohne Weiteres eine fehlerhafte, d.h. eine konstruktiv so nicht vorgesehene Verbindung der Hydraulikleitungen erfolgen.This one-piece embodiment is particularly advantageous when more than two hydraulic lines to be passed through the pivot bearing on the partition plate. It makes it possible to determine on the constructive side from the outset which geometry should occupy the hydraulic lines to each other and to the pivot bearing. Since the partition plate, or its positioning plate is present in one piece, it is by their geometry during assembly clearly before, how to assemble the hydraulic lines in accordance with the design specifications. Namely, once the at least one connecting portion is due to the design specified on the partition plate or on the integrally executed positioning plate, so during the assembly process is no longer readily a faulty, ie a structurally so not provided connection of the hydraulic lines.

In einem weiteren bevorzugten Ausführungsbeispiel ist es denkbar, dass die wenigstens eine Trennplatte aus einem verbindungssteifen Material wie einem Metall, einer Metalllegierung, einem Faserverbundwerkstoff oder einem Kunststoff mit vergleichbaren Eigenschaften bereitgestellt ist.In a further preferred embodiment, it is conceivable that the at least one partition plate is made of a connection-resistant material such as a metal, a metal alloy, a fiber composite material or a plastic with comparable properties.

Die entsprechende Materialwahl ermöglicht es dabei vorteilhafterweise die Relativbewegungen einerseits zwischen den Hydraulikleitungen untereinander und andererseits zwischen den Hydraulikleitungen und dem Schwenklager zu minimieren. Da üblicherweise Arbeitsausrüstungen im Sinne der Erfindung aus Stählen gefertigt werden, liegt hier die Verwendung einer Stahltrennplatte aus ebendiesem Material nahe. Nichtsdestotrotz ist erfindungsgemäß auch jedes andere Material denkbar, welches eine die Hydraulikleitungen fixierende Anordnung ermöglicht.The appropriate choice of material makes it possible advantageously to minimize the relative movements on the one hand between the hydraulic lines to each other and on the other hand between the hydraulic lines and the pivot bearing. Since usually work equipment in the context of the invention are made of steels, the use of a steel parting plate made of this material is the obvious choice. Nonetheless, according to the invention, any other material is also conceivable which allows a structure fixing the hydraulic lines.

In einem weiteren bevorzugten Ausführungsbeispiel ist es denkbar, dass die wenigstens eine Trennplatte im Bereich des Drehmittelpunkts des wenigstens einen Schwenklagers vorgesehen ist.In a further preferred embodiment, it is conceivable that the at least one partition plate is provided in the region of the center of rotation of the at least one pivot bearing.

Auf diese Art wird vorteilhafterweise sichergestellt, dass die Bewegung der Hydraulikleitungen, welche für die Kräfte ursächlich sind, die von den Hydraulikleitungen in das Schwenklager eingeleitet werden, möglichst gering gehalten werden.In this way it is advantageously ensured that the movement of the hydraulic lines, which are the cause of the forces that are introduced from the hydraulic lines in the pivot bearing, are kept as low as possible.

In einem weiteren bevorzugten Ausführungsbeispiel ist es denkbar, dass die Hydraulikleitungen im Innenbereich der Arbeitsausrüstung angeordnet sind.In a further preferred embodiment, it is conceivable that the hydraulic lines are arranged in the interior of the work equipment.

Diese Schlauchverlegung durch das Schwenklager ermöglicht es vorteilhafterweise zum einem dem Fahrer eine bessere Geräteübersicht zu verschaffen, da seine Sicht so nicht durch Hydraulikleitungen eingeschränkt wird, welche entlang der Arbeitsausrüstung verlaufen und mithin den für den Fahrer relevantesten Arbeitsbereich betreffen. Zum anderen wird aufgrund der innenliegenden Verlegung der Hydraulikleitungen die Möglichkeit von Beschädigungen der Hydraulikleitungen durch äußere Einflüsse, wie sie im Baustellenbetrieb durch Kontakt mit Baustellenstrukturen verursacht werden können ausgeschlossen.This hose routing through the pivot bearing advantageously allows the driver to get a better overview of the equipment, as his vision is not limited by hydraulic lines running along the work equipment and therefore concern the most relevant work area for the driver. On the other hand, due to the internal laying of the hydraulic lines the possibility of damage to the hydraulic lines by external influences, as they can be caused in construction site operation by contact with construction sites structures excluded.
