Description

Die Erfindung bezieht sich auf einen Mäkler nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a broker according to the preamble of claim 1.

Für die im Spezialtiefbau anfallenden Arbeiten, wie Bohren, Pressen, Rammen etc. werden Mäkler eingesetzt, der einen Mast mit Führungsschiene darstellt, entlang der ein Schlitten gleitet, welcher zur Aufnahme von Arbeitsgeräten wie Bohrgeräten, Vibratoren, Schnellschlaghämmer, Dieselbären, Pressen und dergl. ausgebildet ist. Der Mäkler ist in der Regel an einen Hydraulikbagger angebaut. Seine Aufgabe besteht darin, die Arbeitsgeräte zu führen und Anpress- und Zugkräfte zu erzeugen. Die Mäkler sind entweder zur Durchführung einer Aufgabe konzipiert, oder, wie bei den Universalmäklern, für Arbeiten mit verschiedenen Arbeitsgeräten ausgelegt. Bei den Universalmäklem überwiegen Ausführungsformen, bei denen die Arbeitsgeräte konventionell mit Schrauben und Bolzen fest am Schlitten des Mäklers angebaut sind. Ein Austausch des Arbeitsgerätes dauert bei Mäklern dieser Art daher in der Regel mehrere Stunden.For the work involved in special civil engineering, such as drilling, pressing, ramming etc., brokers are used, which represents a mast with guide rail along which slides a slide, which is suitable for holding tools such as drills, vibrators, quick hammers, diesel bears, presses and the like. is trained. The broker is usually attached to a hydraulic excavator. Its task is to guide the tools and to create contact and tensile forces. The brokers are either designed to perform a task, or, as with the universal leader, designed for working with various equipment. In the Universalmäklem outweigh embodiments in which the tools are conventionally mounted with screws and bolts firmly on the slide of the leader. An exchange of the implement therefore takes in Mäklern of this kind therefore usually several hours.

Bei Vorrichtungen nach dem Stand der Technik ist die Zielrichtung bei dem Bemühen, den Zeitaufwand beim Wechsel der Arbeitsgeräte zu verringern, darauf gerichtet, die mechanischen Aufnahmevorrichtungen zu optimieren. So wird beispielsweise bei der DE 43 12 368 A1 eine Zeiteinsparung beim Gerätewechsel dadurch erzielt, daß die mechanische Verbindung zwischen Arbeitsgerät und Hubschlitten mit einer hydraulischen Verriegelung hergestellt wird.In prior art devices, in an effort to reduce the time required to change tools, the aim is to optimize the mechanical pickup devices. For example, at the DE 43 12 368 A1 a time saving when changing equipment achieved in that the mechanical connection between the implement and lifting is made with a hydraulic lock.

Daneben gibt es auch Mäkler, die mit Wechselvorrichtungen ausgerüstet sind. Bei Mäklern dieser Art sind die Arbeitsgeräte als Tauschgeräte konzipiert. Sie sind auf einem Führungsschlitten montiert, der in der Führungsschiene des Mäklers gleitet. Beim Austausch des Arbeitsgerätes wird der Führungsschlitten mitsamt Arbeitsgerät aus der Führungsschiene herausgefahren und statt dessen eine komplette Einheit aus Führungsschlitten und vorgesehenem Arbeitsgerät wieder eingesetzt. Für diesen Tauschvorgang ist nur ein geringer zeitlicher Aufwand erforderlich.In addition, there are also lawyers who are equipped with changing devices. For Makers of this type, the tools are designed as exchange devices. They are mounted on a guide slide, which slides in the guide rail of the leader. When replacing the implement, the guide carriage is moved out together with the implement from the guide rail and instead used a complete unit of guide carriage and provided implement again. For this exchange process only a small amount of time is required.

Mit dem Austausch des Arbeitsgerätes allein ist der Wechsel von einem auf ein anderes Arbeitsgerät jedoch noch nicht vollzogen. Um das ausgetauschte Gerät einsatzbereit zu machen, ist es notwendig, auch die elektrischen und hydraulischen Versorgungsleitungen anzuschließen. Bei Geräten nach dem Stand der Technik ist für diesen Vorgang ein wesentlich größere Zeitaufwand notwendig als für das Austauschen der Geräte. Bei den bekannten Wechselvorrichtungen werden die hydraulischen und elektrischen Verbindungen zwischen Arbeitsgerät und Grundschlitten per Hand hergestellt. Dabei gehört zu diesem Arbeitsschritt nicht nur die Verschraubung der Hydraulikleitungen mit den zugehörigen Anschlüssen, sondern auch die Einstellung von Ölmenge, Flußrichtung und Betriebsdruck entsprechend den speziellen Erfordernissen des verwandten Arbeitsgeräts. Für diese Vorgänge müssen Betriebswahlschalter und Kugelhähne in die jeweils richtigen Positionen gebracht werden. Als Nachteil mit gegebenenfalls gravierenden Folgen ist hierbei der Unsicherheitsfaktor anzusehen, der dadurch gegeben ist, daß bei der Durchführung dieser Arbeiten menschliche Irrtümer nicht auszuschließen sind. Aus der DE-U-29810118 ist ein hydraulisches Schnellwechsel-Kupplungssystem bekannt.However, with the replacement of the implement alone the change from one to another implement is not yet completed. In order to make the replaced device ready for use, it is necessary to also connect the electrical and hydraulic supply lines. In devices according to the prior art, a much greater expenditure of time is required for this process than for the replacement of the devices. In the known changing devices, the hydraulic and electrical connections between the implement and base carriage are made by hand. In this process, not only the screwing of the hydraulic lines with the associated connections, but also the adjustment of oil quantity, flow direction and operating pressure according to the specific requirements of the related implement belongs to this step. For these operations, operation selector switches and ball valves must be brought into the correct positions. The disadvantage with possibly serious consequences here is the uncertainty factor to be considered, which is given by the fact that human errors can not be ruled out in carrying out this work. From the DE-U-29810118 a hydraulic quick-change coupling system is known.

Insgesamt erfordern diese Arbeiten viel Zeit, so daß auch bei Mäklem mit Wechselvorrichtung für den kompletten Wechselvorgang - Austausch des Arbeitsgerätes und Trennen und Neu-Anschluß der Versorgungsleitungen - ein hoher Zeitaufwand notwendig ist.Overall, this work requires a lot of time, so that even with Mäklem with changing device for the complete change process - replacement of the implement and disconnecting and reconnecting the supply lines - a lot of time is required.

Darüber hinaus ist es auch von Nachteil, daß während des Wechselvorganges die Enden der Hydraulikleitungen und die zugehörigen Anschlüsse offen und ungeschützt da liegen. Hierdurch ist die Gefahr gegeben, daß einerseits Schmutz in das hydraulische Leitungssystem eindringen kann und andererseits für die Umwelt abträgliches Hydrauliköl aus dem Leitungssystem austreten kann.Moreover, it is also a disadvantage that during the change process, the ends of the hydraulic lines and the associated ports are open and unprotected there. As a result, there is the danger that on the one hand dirt can penetrate into the hydraulic line system and on the other hand can escape for the environment detrimental hydraulic oil from the pipe system.

Vor diesem Hintergrund hat sich die Erfindung die Aufgabe gestellt, eine Wechselvorrichtung anzugeben, welche den kompletten Wechselvorgang beim Austausch von Arbeitsgeräten erheblich verkürzt, ein leckagefreies Wechseln ermöglicht, und zudem Fehlschaltungen infolge menschlicher Irrtümer ausschließt.Against this background, the invention has set itself the task of specifying a changing device, which significantly shortens the entire change process when replacing equipment, allows leakage-free switching, and also eliminates errors due to human error.

Diese Aufgabe wird durch die Merkmale des kennzeichnenden Teils des Patentanspruchs gelöst.This object is solved by the features of the characterizing part of the claim.

Dabei trägt der Führungsschlitten das Arbeitsgerät, während der Grundschlitten die Versorgungsleitungen für das Arbeitsgerät zur Verfügung stellt.The guide carriage carries the implement while the base carriage provides the supply lines for the implement.

Gemäß vorliegender Erfindung ist der Grundschlitten mit einer Platte mit Kuppelelementen ausgestattet. Diese Platte arbeitet mit einem Kupplungsblock zusammen, der am Führungsschlitten montiert ist und mit Gegenaufnahmen für die Kuppelelmente ausgestattet ist. Während des Betriebes sind beide Schlitten mit einer in der Regel hydraulisch arbeitenden Verriegelungsvorrichtung fest mit einander verbunden. In dieser Position greifen die Kuppelelemente der Platte in die Gegenaufnahmen im Kupplungsblock ein und stellen so die hydraulische Verbindung zwischen Grundschlitten und Arbeitsgerät her.According to the present invention, the base carriage is equipped with a plate with coupling elements. This plate cooperates with a coupling block, which is mounted on the guide carriage and equipped with counter-receptacles for the dome elements. During operation, both carriages are connected to one another with a generally hydraulically operating locking device. In this position, the coupling elements of the plate engage in the Countermounts in the coupling block and thus establish the hydraulic connection between the base carriage and implement.

Mit derart ausgestatteten Grund- und Führungsschlitten läßt sich der Wechsel der Arbeitsgeräte an Universalmäklern in kürzester Zeit durchführen.With basic and guide carriages equipped in this way, it is possible to carry out the change of working tools to universal trailers in the shortest possible time.

Zur Demontage eines Arbeitsgerätes setzt der Mäkler das Arbeitsgerät auf einer stabilen Unterlage ab. Anschließend werden die zum Arbeitsgerät führenden Hydraulikleitungen drucklos geschaltet und die Verriegelungsvorrichtungen zwischen Grund- und Führungsschlitten gelöst. Dadurch wird die mechanische Verbindung zwischen Grund- und Führungsschlitten aufgehoben. Anschließend wird der Grundschlitten hochgefahren, während der Führungsschlitten mit Arbeitsgerät auf der Unterlage verharrt. Bei diesem Vorgang werden sämtliche zum Arbeitsgerät führenden hydraulischen Zuführungen vom Arbeitsgerät getrennt. Die Trennung erfolgt dadurch, daß die Kuppelelemente der am Grundschlitten befestigten Platte aus den entsprechenden Gegenaufnahmen des am Führungsschlitten befestigten Kupplungsblocks herausgefahren werden. Damit ist die Demontage des Arbeitsgerätes nahezu vollzogen. Es bleibt lediglich das Ausfädeln des Arbeitsgerätes aus der Führungsschiene des Mäklers. Dieser Vorgang wird durch Hochfahren des Mäklers durchgeführt.To disassemble a tool, the broker sets the implement on a stable surface. Subsequently, leading to the implement hydraulic lines are depressurized and released the locking devices between the base and guide carriage. As a result, the mechanical connection between the base and guide carriage is canceled. Subsequently, the base carriage is raised while the guide carriage remains on the base with the implement. During this process, all hydraulic feeds leading to the implement are disconnected from the implement. The separation takes place in that the coupling elements of the plate attached to the base carriage are moved out of the corresponding counter-receptacles of the coupling block attached to the guide carriage. Thus, the disassembly of the implement is almost completed. It remains only the unthreading of the implement from the guide rail of the leader. This process is performed by raising the leader.

Bei der Montage eines Arbeitsgerätes werden die einzelnen Arbeitsschritte in umgekehrter Reihenfolge durchlaufen.When mounting a tool, the individual steps are performed in reverse order.

Zur Durchführung eines kompletten Wechselvorgangs - Austausch des Arbeitsgerätes und Trennen und Neu-Anschluß der Versorgungsleitungen - muß ein mit der erfindungsgemäßen Vorrichtung ausgestatteter Mäkler nur für sehr kurze Zeiten außer Betrieb gesetzt werden. Da Stillstandzeiten für hochtechnisierte Geräte, wie Mäkler, sehr kostspielig sind, lassen sich mit vorliegender Erfindung erhebliche Kosten einsparen.To carry out a complete change process - replacement of the implement and disconnecting and reconnecting the supply lines - a equipped with the device according to the invention Makers must be set only for very short periods out of service. Since downtime for high-tech equipment, such as brokers, are very expensive, can be saved considerable costs with the present invention.

Auch aus Sicht der Betriebssicherheit bringt die vorgeschlagenene Wechselvorrichtung eine Verbesserung mit sich. Beim Stand der Technik ist die Gefahr gegeben, daß beim Verbinden der hydraulischen Anschlüsse menschliche Irrtümer unterlaufen und dadurch Fehlschaltungen verursacht werden. Diese Möglichkeit ist bei vorliegender Erfindung von vorne herein ausgeschlossen, da die hydraulischen Verbindungen ohne menschliches Zutun hergestellt werden.Also from the point of view of operational safety brings the proposed changing device with an improvement. In the prior art, there is the danger that when connecting the hydraulic connections human error undermined and thereby faulty circuits are caused. This possibility is excluded in the present invention from the outset, since the hydraulic connections are made without human intervention.

Von Vorteil ist eine Ausführungsform der vorgeschlagenen Wechselvorrichtung, bei der die Kuppelelemente oder Gegenaufnahmen als Ventile ausgebildet sind und die Ventile eine Vorrichtung aufweisen, durch welche sie schließund öffenbar sind. Dabei schließt genannte Vorrichtung die Ventile beim Auseinanderfahren von Platte und Kupplungsblock. Dadurch wird verhindert, daß einerseits Hydrauliköl freigesetzt wird und andererseits Schmutzteilchen in die Hydraulikleitungen eindringen können. Beim Zusammenfahren von Platte und Block werden dagegen die Ventile durch die genannte Vorrichtung geöffnet.An advantage of an embodiment of the proposed changing device in which the coupling elements or counter-receptacles are formed as valves and the valves have a device by which they are Schließund openable. In this case, said device closes the valves when moving apart of plate and coupling block. This prevents that on the one hand hydraulic oil is released and on the other hand dirt particles can penetrate into the hydraulic lines. When moving plate and block, however, the valves are opened by said device.

Um die Ventile während der Zeit, in der Platte und Block nicht miteinander gekuppelt sind, vor mechanischer Beschädigung zu schützen, hat es sich bewährt, wenn die auf der Platte angeordneten Kuppelelemente in Form von Steckern, die Gegenaufnahmen auf dem Kupplungsblock in Form von Muffen ausgebildet sind. Bei dieser Ausgestaltung werden die Stecker der am Grundschlitten befestigten Platte durch die ebenfalls am Grundschlitten befestigte Verriegelungsvorrichtung zum großen Teil abgeschirmt und daher vor mechanischen Beschädigungen geschützt.In order to protect the valves against mechanical damage during the time in which the plate and block are not coupled together, it has proven useful if the coupling elements arranged on the plate in the form of plugs, the counter-receptacles on the coupling block in the form of sleeves formed are. In this embodiment, the plug of the base carriage attached to the plate are also shielded by the locking device also attached to the base carriage and therefore protected from mechanical damage.

Platte und Block weisen in der Regel mehrere hydraulisch beaufschlagbare Kuppelelemente bzw. Gegenaufnahmen auf. Da unterschiedliche Arbeitsgeräte mitunter auch jeweils eine unterschiedliche Anzahl von hydraulischen Leitungen erfordern, ist die Zahl der Kuppelelemente bzw. der Gegenaufnahmen so bemessen, daß bei Einsatz der verschiedenen Arbeitsgeräte die jeweils erforderlichen Hydraulikleitungen zur Verfügung gestellt werden. Bei einer vorteilhaften Ausführungsform entspricht daher die Anzahl der Kuppelelemente und der Gegenaufnahmen gleich der Maximalzahl der bei den unterschiedlichen Arbeitsgeräten auftretenden Hydraulikleitungen.Plate and block generally have a plurality of hydraulically actuable coupling elements or counter-recordings. Since different tools sometimes require a different number of hydraulic lines, the number of coupling elements and the counter-receptacles is dimensioned so that when using the various tools each required hydraulic lines are provided. In an advantageous embodiment, therefore, corresponds to the number of coupling elements and the counter-receptacles equal to the maximum number of hydraulic lines occurring in the different equipment.

Nach dem Einfädeln des Arbeitsgerätes in die Führungsschiene des Mäklers werden Grund- und Führungsschlitten zusammengefügt und mit der Verriegelungsvorrichtung mit einander verbunden. Bei dem Fügevorgang müssen die als Stecker ausgebildeten Kuppelelemente der Platte in die als Muffen ausgebildeten Gegenaufnahmen am Kupplungsblock eingeführt werden. Um ein belastungsfreies Einkoppeln zu erreichen, ist es von Vorteil, wenn die Platte schwimmend gelagert ist und Elemente zum Ausrichten der Platte in der Plattenebene aufweist, die mit den entsprechenden Gegenelementen im Kupplungsblock zusammenarbeiten. Diese Elemente stellen in Zusammenwirken mit der schwimmenden Lagerung der Platte sicher, daß Platte und Kupplungsblock exakt ausgerichtet werden, bevor die Stecker in die entsprechenden Muffen eingreifen.After threading the implement into the guide rail of the leader, the base and guide carriages are joined together and connected to the locking device with each other. In the joining process designed as a plug coupling elements of the plate must be introduced into the counter-receptacles formed as sleeves on the coupling block. In order to achieve a load-free coupling, it is advantageous if the plate is floating and has elements for aligning the plate in the plane of the plate, which cooperate with the corresponding counter-elements in the coupling block. These elements, in cooperation with the floating support of the plate, ensure that the plate and coupling block are precisely aligned before the plugs engage the respective sleeves.

Die Ausbildung der Stecker als Ventile, die sich beim Einführen in den Kupplungsblock selbsttätig öffnen und bei Ausfahren aus dem Kupplungsblock dementsprechend selbsttätig schließen, verhindern, daß Hydrauliköl in größeren Mengen freigesetzt wird. Da bei einem Gerätewechsel mitunter dennoch Leckageöl anfällt, ist bei einer Weiterbildung der Wechselvorrichtung der Kupplungsblock auf der Seite der Gegenaufnahmen mit einem Leckölkanal ausgestattet. Dieser Kanal dient zur Aufnahme und Weiterleitung des Leckageöls an eine Ölauffangwanne.The formation of the plug as valves that automatically open when inserted into the coupling block and accordingly close automatically when extending out of the coupling block, prevent hydraulic oil is released in large quantities. Since leaking oil sometimes occurs during a device change, the coupling block on the side of the counter receptacles is equipped with a leakage oil channel in a further development of the changing device. This channel is used to receive and forward the leakage oil to an oil sump.

Bei einem gemäß vorliegender Erfindung ausgebildeten Mäkler werden die hydraulischen Verbindungen zwischen Grundschlitten und Arbeitsgerät selbsttätig hergestellt. Die unterschiedliche Betriebsweise der einzelnen Arbeitsgeräte erfordert jedoch die Einstellung unterschiedlicher Betriebsbedingungen, wie Einstellung von Ölmenge, Flußrichtung und Betriebsdruck. Um auch diese Arbeitsschritte zu automatisieren und frei von menschlichen Fehlleistungen zu halten, ist das Arbeitsgerät mit einer Speichereinheit ausgerüstet, in der Informationen über das Arbeitsgerät, vorzugsweise hydraulische und elektrische Betriebsdaten, abgelegt sind. Von Vorteil ist es wenn die Speichereinheit batterielos, vorzugsweise unter Verwendung von einem NMOS-EPROM oder FRAM, betrieben wird.In a trained according to the present invention leader the hydraulic connections between the parent carriage and implement are made automatically. However, the different operation of the individual tools requires the setting of different operating conditions, such as adjustment of oil quantity, flow direction and operating pressure. Around To automate these steps and to keep free of human errors, the implement is equipped with a memory unit in which information about the implement, preferably hydraulic and electrical operating data stored. It is advantageous if the memory unit is battery-free, preferably using an NMOS-EPROM or FRAM operated.

Die Speichereinheit arbeitet drahtlos, vorzugsweise mittels elektromagnetischer Induktion, mit einem am Führungs- oder Grundschlitten vorgesehenen Lese-/Schreibgerät für elektronische Daten zusammen. Das Lesegerät leitet dabei aus der Speichereinheit ausgelesene Daten als Signale an die Maschinensteuerung des Mäklers und/oder Signale von der Maschinensteuerung als Daten an die Speichereinheit weiter. Die Kommunikation zwischen Lese- und Schreibgerät und der Maschinensteuerung erfolgt in der Regel über eine serielle Schnittstelle.The storage unit operates wirelessly, preferably by means of electromagnetic induction, together with an electronic data reader / writer provided on the guide or base carriage. The reading device forwards data read from the memory unit as signals to the machine control of the leader and / or signals from the machine control as data to the memory unit. The communication between reading and writing device and the machine control is usually via a serial interface.

Aus der Speichereinheit ausgelesenen Daten betreffen die Betriebsdaten des Arbeitsgerätes. Aufgrund dieser Informationen werden die Hydraulikleitungen zu den Ventilen auf der am Grundschlitten befestigten Platte freigeschaltet und hydraulisch beaufschlagt. An die Speichereinheit weitergegebene Daten können beispielsweise die Betriebsstunden oder auch Zeiten besonderer Betriebszustände, wie z. B. Überlastungen, festhalten. Insgesamt können auf diese Weise Daten erfaßt werden, die zur Wartung, zum Erhalt oder zur Reparatur des Arbeitsgerätes notwendig sind.Data read from the storage unit relates to the operating data of the implement. Based on this information, the hydraulic lines to the valves on the plate attached to the base carriage are released and hydraulically acted upon. Data passed to the memory unit may include, for example, the hours of operation or times of particular operating conditions, such as periods of operation. As overloads, hold on. Overall, this data can be detected, which are necessary for maintenance, maintenance or repair of the implement.

Die Speichereinheit und die Lese-/Schreibeinheit ermöglichen ein selbsttätiges Erkennen des Arbeitsgerätetyps und aller für den Betrieb dieses Gerätes relevanter Daten. Fehlbedienungen durch manuelle Eingriffe sind daher ausgeschlossen.The memory unit and the read / write unit allow automatic recognition of the type of implement and all data relevant to the operation of this device. Operating errors due to manual intervention are therefore excluded.

Die in der Speichereinheit abgelegten Daten können auch außerhalb der Betriebszeiten des Mäklers von Interesse sein. Daher ist bei vorliegender Erfindung auch ein Handterminal vorgesehen, das die Eigenschaften des Lesegerätes aufweist und die Daten aus der Speichereinheit abzufragen gestattet.The data stored in the memory unit may also be of interest outside the operating hours of the author. Therefore, in the present invention, a hand-held terminal is provided which has the characteristics of the reading device and allows to query the data from the memory unit.

Ein Arbeitsgerät weist neben den hydraulischen Zuleitungen in der Regel auch elektrische Zuleitungen auf. Zuleitungen elektrischer Art oder Datenleitungen sind auch für die Leseeinheit erforderlich. Diese Leitungen sind zwischen Grundschlitten und Arbeitsgerät daher mit Steckverbindungen ausgerüstet. Bei einer bevorzugten Ausführungsform sind die Steckverbindungen zwischen Grundschlitten und Innenseite der Verriegelungsvorrichtung ausgebildet. Durch diese Ausbildung erreicht man, daß im gleichen Arbeitsgang mit dem Schließen bzw. Öffnen der Verriegelungsvorrichtung auch die elektrischen Verbindungen geschlossen bzw. geöffnet werden. Daneben erbringt diese Anordnung für die Steckverbindungen auch einen gewissen Schutz sowohl vor mechanischen Beschädigungen als auch gegen Öl und Feuchtigkeit in den Zeiträumen, in denen Grund- und Führungsschlitten voneinander getrennt sind.A working device usually has electrical supply lines in addition to the hydraulic supply lines. Feeders of electrical type or data lines are also required for the reading unit. These cables are therefore equipped with basic connections and work equipment with plug connections. In a preferred embodiment, the connections between the base carriage and the inside of the locking device are formed. Through this training, it is achieved that in the same operation with the closing or opening of the locking device and the electrical connections are closed or opened. In addition, this arrangement provides for the connectors also some protection both against mechanical damage as well as against oil and moisture in the periods in which the base and guide carriages are separated.
