Description

Die Erfindung betrifft einen hydraulischen Drehmotor mit Kabeldurchführung sowie einen Bagger bzw. Kran bzw. eine Umschlagmaschine mit einem derartigen Drehmotor.The invention relates to a hydraulic rotary motor with a cable entry and a Excavator or crane or a material handling machine with such a rotary motor.

Kräne, Bagger oder Umschlagmaschinen, insbesondere mobile derartige Fahrzeuge / Maschinen werden in den unterschiedlichsten Gebieten im Umfeld des Güterumschlags, des Handlings von Schrott, Holz, Recyclingstoffen, des Abbruchs oder der Bauindustrie eingesetzt. Damit derartige Fahrzeuge / Maschinen, welche nicht unerhebliche Anschaffungskosten für die Betreiber bedeuten, für möglichst vielfältige Aufgaben einsetzbar sind, sind an deren Auslegern häufig mehrere unterschiedliche Arbeitswerkzeuge oder sogar Multifünktionsköpfe anbringbar. Diese Arbeitswerkzeuge bzw. die Multifünktionsköpfe müssen für die unterschiedlichen Einsatzaufgaben bezüglich des Armes des Kranes drehbar sein. Dazu werden hydraulische Drehmotoren einsetzt, welche beispielsweise umlaufende Arbeitsdruckkammern aufweisen, welche in Umfangsrichtung mittels eines Verteilers nacheinander mit einer Hydraulikflüssigkeit gespeist werden, so dass bei dieser Druckbeaufschlagung der Arbeitskammem mit Hydraulikflüssigkeit eine Drehbewegung entsteht, welche auf den Rotor und demzufolge auf die mit dem Rotor verbundenen Arbeitswerkzeuge übertragen wird. Ein Drehmotor dieses Typs (Zahnringbauweise) ist beispielsweise in der DE 42 02 466 C2 beschrieben.Cranes, excavators or material handling machines, in particular mobile vehicles of this type / Machines are used in a wide variety of areas in the area of cargo handling, of handling scrap, wood, recycling materials, demolition or the construction industry used. Thus such vehicles / machines, which are not insignificant Acquisition costs for the operator mean for as diverse tasks as possible can be used, there are often several different booms Work tools or even multifunction heads can be attached. These work tools or the multifunction heads have to be used for the different tasks the arm of the crane to be rotatable. Hydraulic rotary motors are used for this, which, for example, have circumferential working pressure chambers, which in Circumferential direction in succession with a hydraulic fluid using a distributor are fed, so that with this pressurization of the working chambers with Hydraulic fluid creates a rotational movement, which on the rotor and consequently is transferred to the work tools connected to the rotor. A rotary motor this type (ring gear construction) is described for example in DE 42 02 466 C2.

In einem Umfeld, wie es das beim Güterumschlag, beim Recycling, in der Bauindustrie oder auf Schrottplätzen darstellt, sind extrem robuste Einsatzbedingungen vorhanden. Dazu werden die Hydraulikleitungen im Arm des Fahrzeuges / der Maschine bis hin zu dem Drehmotor verlegt und auch zu den Arbeitswerkzeugen weitergeführt, so dass sowohl die Drehbewegung als auch die Bewegung des Arbeitswerkzeuges beispielsweise zum Öffnen und Schließen von Schaufeln hydraulisch realisiert werden. Es gibt auch eine Reihe von Arbeitswerkzeugen, bei welchen neben der Hydraulikversorgung auch zusätzliche Kabel zur Versorgung mit Antriebsstrom oder mit Steuerstrom erforderlich sind. Bei den bekannten Drehmotoren und bekannten Fahrzeugen, Kränen bzw. Maschinen, bei welchen derartige Drehmotoren eingesetzt werden, erfolgt eine äußere Trennung zwischen hydraulischem Antrieb und Elektroversorgung. So sind beispielsweise bei einem Arbeitswerkzeug in Form eines Elektromagneten Stromkabel um den Drehmotor außen herum zum Elektromagneten, welcher sich unterhalb des Drehmotors am Kranarm befindet, geführt. Bei den robustem Einsatzbedingungen ist eine Beschädigung eines außenliegenden Stromkabels nicht auszuschließen. Ein außenliegendes Stromkabel, das im robusten Einsatz beschädigt wird, stellt jedoch eine starke Gefährdung für die beispielsweise im Bereich eines Schrottplatzes arbeitenden Personen dar.In an environment like that of goods handling, recycling, in the construction industry or in scrap yards, there are extremely robust operating conditions. For this purpose, the hydraulic lines in the arm of the vehicle / machine up to relocated the rotary motor and also continued to the work tools, so that both the rotary movement as well as the movement of the work tool, for example, for Opening and closing of blades can be realized hydraulically. There are also a number of work tools, which in addition to the hydraulic supply also additional Cables for supplying drive current or control current are required. Both known rotary motors and known vehicles, cranes or machines, in which such rotary motors are used, there is an external separation between hydraulic drive and electrical supply. For example, with one Work tool in the form of an electromagnet power cable around the outside of the rotary motor around to the electromagnet, which is located below the rotary motor on the crane arm located, led. In the tough conditions of use, damage is a external power cable cannot be excluded. An external power cable that in the robust use is damaged, but poses a strong threat to the for example in the area of a scrap yard.

Der Erfindung liegt daher die Aufgabe zugrunde, einen hydraulischen Drehmotor zum Antrieb von Arbeitswerkzeugen an einem Fahrzeug, Kran, einer Maschine sowie ein Fahrzeug, Kran, eine Maschine mit einem derartigen hydraulischen Drehmotor zu schaffen, bei welchem die Versorgungsleitungen für elektrische Antriebe oder Steuerungen von Zusatzaggregaten bzw. für spezielle Funktionen der Arbeitswerkzeuge so geschützt sind, dass diese auch unter robusten Einsatzbedingungen nicht beschädigt werden können, so dass Gefährdungen beispielsweise wegen Stromschlags vermeidbar sind.The invention is therefore based on the object of a hydraulic rotary motor Drive work tools on a vehicle, crane, machine and one Vehicle, crane, a machine with such a hydraulic rotary motor too create in which the supply lines for electrical drives or controls protected by additional units or for special functions of the work tools are that they cannot be damaged even under robust operating conditions, so that hazards, for example due to electric shock, can be avoided.

Diese Aufgabe wird mit einem hydraulischen Drehmotor mit den Merkmalen gemäß Anspruch 1 sowie mit einem Fahrzeug mit den Merkmalen gemäß Anspruch 10 gelöst. Zweckmäßige Weiterbildungen für den erfindungsgemäßen hydraulischen Drehmotor sind in den abhängigen Ansprüchen definiert.This task is accomplished with a hydraulic rotary motor with the features Claim 1 and solved with a vehicle with the features of claim 10. Appropriate developments for the hydraulic rotary motor according to the invention are defined in the dependent claims.

Der erfindungsgemäße Drehmotor zum Antrieb von Arbeitswerkzeugen dient insbesondere auch zum Antrieb der Bewegung eines an einem Fahrzeug / einer Maschine / einem Kran, vorzugsweise an einem mobilen Fahrzeug, angebrachten elektrischen Verbrauchers, wie beispielsweise eines Elektromagneten. Der Drehmotor weist in an sich bekannter Bauart Arbeitsdruckkammern auf, welche mit einer Hydraulikflüssigkeit druckbeaufschlagt werden, so dass dadurch eine Abtriebswelle in eine Umlaufbewegung versetzt wird. Die Abtriebswelle ist mechanisch mit den Arbeitswerkzeugen verbunden, so dass deren Drehbewegung auf das Arbeitswerkzeug übertragen wird. Die Elektroversorgung für einen elektrischen Verbraucher oder für ein Arbeitswerkzeug mit einem elektrischen Verbraucher erfolgt durch eine von außen in einen auch als Stromgehäuse bezeichneten Kopf des Drehmotors eingebrachte und durch das Innere des Drehmotors zu dem Verbraucher geführte Zuleitung. Diese Zuleitung ist relativ einfach in den Kopf des Drehmotors einbringbar, wenn gemäß einem ersten Ausführungsbeispiel der Kopf des Drehmotors stationär ist. Das Innere des Drehmotors ist dabei gegenüber dem Hydraulikkreis so isoliert, dass selbst im Falle eine Kabelbruchs, beispielsweise in der Zuleitung ein Unter-Strom-Setzen des kompletten Motors vermieden werden kann. Vom stationären Kopf des Drehmotors wird vorzugsweise über eine Bürsten-Schleifring-Einrichtung die Stromversorgung durch das Innere des Drehmotors, vorzugsweise durch die Abtriebswelle geführt, so dass ein stromführendes Kabel zentral aus der Abtriebswelle an dessen dem Kopf des Drehmotors abgewandter Seite wieder austreten kann und somit mit dem elektrischen Verbraucher verbindbar ist. Damit ist es einerseits möglich, dass eine direkte Stromversorgung für einen elektrischen Verbraucher oder für bestimmte Funktionen an einem Arbeitswerkzeug, welche vorteilhafterweise mittels Elektromotoren ausführbar sind, durch den Drehmotor geführt werden kann. Es ist jedoch andererseits auch möglich, dass Leitungen zur Übertragung eines Steuersignals bzw. Steuerstromes für entsprechende Aktuatoren beispielsweise an einem Multifunktionskopf durch den Drehmotor geführt werden. Damit ist gewährleistet, dass auch im robusten Einsatz stromführende Leitungen, und zwar selbst solche, welche nur zur Übertragung von Steuerströmen oder Steuersignalen dienen, im Innern des Drehmotors geschützt sind.The rotary motor according to the invention for driving work tools is used in particular also to drive the movement of a on a vehicle / machine / crane, preferably attached to a mobile vehicle, electrical consumer, such as for example an electromagnet. The rotary motor has a design known per se Working pressure chambers, which pressurizes with a hydraulic fluid be so that an output shaft is set in a circular motion. The Output shaft is mechanically connected to the work tools, so that their Rotational movement is transferred to the work tool. The electrical supply for one electrical consumer or for a work tool with an electrical Consumer takes place from the outside in a so-called current housing Head of the rotary motor inserted and through the inside of the rotary motor to the Consumer-led supply line. This supply line is relatively simple in the head of the Rotary motor can be introduced if, according to a first embodiment, the head of the Rotary motor is stationary. The inside of the rotary motor is opposite to that Hydraulic circuit insulated so that even in the event of a cable break, for example in the Power supply to the entire motor can be avoided. from stationary head of the rotary motor is preferably via a brush slip ring device the power supply through the interior of the rotary motor, preferably through the output shaft guided, so that a current-carrying cable centrally from the output shaft on the side facing away from the head of the rotary motor can emerge again and thus is connectable to the electrical consumer. On the one hand, it is possible that a direct power supply for an electrical consumer or for certain Functions on a work tool, which advantageously by means of electric motors are executable, can be guided by the rotary motor. On the other hand, it is also possible that lines for the transmission of a control signal or control current for corresponding actuators, for example on a multifunction head by the Rotary motor are performed. This ensures that even in robust use Live cables, even those that are only for the transmission of Control currents or control signals are used, are protected inside the rotary motor.

Vorzugsweise weist der Drehmotor in an sich bekannter Bauart umlaufende Arbeitsdruckkammern auf und ist in Zahnringbauweise ausgeführt. Ein mit der Abtriebswelle vorhandener Rotor kämmt mit einem Rotorring und bildet dazwischen die Arbeitsdruckkammern, wobei Rotor und Rotorring zwischen Verteilerplatten gehalten sind, über welche die Versorgung der Arbeitsdruckkammern mit Hydraulikfluid erfolgt. The rotary motor preferably has a rotating design in a manner known per se Working pressure chambers and is designed in a toothed ring design. One with the The output shaft of the existing rotor meshes with a rotor ring and forms the one in between Working pressure chambers, with the rotor and rotor ring held between the distributor plates are used to supply the working pressure chambers with hydraulic fluid.

Die Arbeitsdruckkammern werden in Umfangrichtung nacheinander mit Hydraulikfluid versorgt.The working pressure chambers are successively circumferentially with hydraulic fluid provided.

Im stationär angeordneten, das Stromgehäuse des Drehmotors bildenden Kopf ist ein als Isolator ausgebildeter Kabelhalter angeordnet, über welchen der Strom von der Bürsten-Schleifring-Einrichtung durch den Motor geleitet wird. Prinzipiell ist es möglich, dass sich die Bürsten an dem Kopf des Drehmotors befinden, wohingegen der Schleifring oder die Schleifringe an einem in den Bereich des Kopfes geführten Bereich der Abtriebswelle angeordnet sind. Selbstverständlich ist auch die Umkehrung möglich, das heißt die Schleifringe sind an dem stationären Kopf des Drehmotors angeordnet, wohingegen die Bürsten an der Abtriebswelle angeordnet bzw. mit einem Teil der Abtriebswelle verbunden sind. Selbstverständlich sind für die unmittelbare Stromversorgung sowie für die Übertragung von Steuerströmen oder Signalen unterschiedliche Teile einer derartigen Bürsten-Schleifring-Einrichtung oder mehrere auch unterschiedliche solcher Einrichtungen vorgesehen.In the stationary head, which forms the current housing of the rotary motor, there is an as Insulator trained cable holder arranged over which the current from the brush slip ring device is passed through the engine. In principle, it is possible that the brushes are on the head of the rotary motor, whereas the slip ring or the Slip rings on an area of the output shaft led into the area of the head are arranged. Of course, the reverse is also possible, that is Slip rings are arranged on the stationary head of the rotary motor, whereas the Brushes arranged on the output shaft or connected to part of the output shaft are. Of course, for the direct power supply as well as for the Transmission of control currents or signals different parts of such Brush slip ring device or several different such devices intended.

Vorzugsweise ist die Abtriebswelle, welche vorzugsweise als Flanschwelle ausgebildet ist, für ein leichtes Anschließen der Arbeitswerkzeuge zentral mit einer Bohrung versehen, durch welche die stromführende Zuleitung geführt ist. Es ist jedoch auch möglich, separate Kanäle im zentralen Bereich der Abtriebswelle des Drehmotors vorzusehen, so dass die stromführenden Zuleitungen beispielsweise in einem derartigen Kanal oder in mehreren Kanälen geführt ist bzw. sind, wohingegen die Leitungen für Steuersignale oder für Steuerströme in davon verschiedenen Kanälen geführt sein können. Es versteht sich, dass es im Falle des Austretens von Kabeln außerhalb des unmittelbaren zentralen Bereiches der Abtriebswelle an der dem Kopf des Drehmotors gegenüberliegenden Seite erforderlich ist, ebenfalls vorzugsweise eine Bürsten-Schleifring-Einrichtung vorzusehen. Dies hängt jedoch von der jeweiligen Konstruktion des Arbeitswerkzeuges bzw. des elektrischen Verbrauchers ab.The output shaft, which is preferably designed as a flange shaft, is preferably Provide a central hole for easy connection of the work tools, through which the live supply line is led. However, it is also possible to have separate Provide channels in the central area of the output shaft of the rotary motor, so that the current-carrying leads, for example, in such a channel or in several Channels is or are, whereas the lines for control signals or for Control currents can be routed in different channels. It goes without saying that it in the event of cables leaking outside the immediate central area of the Output shaft on the side opposite the head of the rotary motor is required, also preferably to provide a brush slip ring device. This depends however of the respective construction of the work tool or the electrical Consumer.

Besonders bevorzugt ist die Verwendung eines erfindungsgemäßen hydraulischen Drehmotors bei einem Fahrzeug, einer Maschine, einem Kran, welcher bzw. welche einen Elektromagneten aufweist, das heißt ein Fahrzeug, welches beispielsweise im Schrottbereich eingesetzt ist. Bei einem derartigen Fahrzeug mit einem erfindungsgemäßen Hydraulikdrehmotor, einem sogenannten Strommotor, und einem Elektromagneten als Arbeitswerkzeug ist es besonders vorteilhaft, wegen der extrem rauhen Einsatzbedingungen das Magnetkabel völlig geschützt durch den Drehmotor hindurchzuführen.The use of a hydraulic device according to the invention is particularly preferred Rotary motor in a vehicle, a machine, a crane, which one Has electromagnets, that is, a vehicle which, for example, in the Scrap area is used. In such a vehicle with an inventive Hydraulic rotary motor, a so-called current motor, and an electromagnet as Working tool, it is particularly advantageous because of the extremely rough Operating conditions the magnetic cable is fully protected by the rotating motor pass therethrough.
