Description

Die Erfindung betrifft einen Adapter für ein Schnellwechselsystem nach dem Oberbegriff der Anspruchs 1. Die Erfindung betrifft außerdem ein Schnellwechselsystem mit einem derartigen Adapter.The invention relates to an adapter for a quick-change system according to the preamble of claim 1. The invention also relates to a quick-change system with an adapter of this type.

Solche Schnellwechselsysteme werden zum einfachen und bequemen Wechseln von unterschiedlichen Anbaugeräten an Baumaschinen eingesetzt. Mit derartigen Schnellwechselsystemen können z.B. Schwenklöffel, Greifer, Scheren, Verdichter, Magnete, Hydraulikhammer oder andere Anbaugeräte in wenigen Sekunden und mit hohem Sicherheitsstandard von einer Fahrerkabine aus z.B. an einem Ausleger eines Baggers an- bzw. abgekuppelt werden. Sie enthalten in der Regel einen anbaugeräteseitigen Adapter und einen an der Baumaschine angeordneten Schnellwechsler, der an einer Seite z.B. maulförmige erste Aufnahmen zur Halterung eines ersten Kopplungselements und an der anderen Seite zweite Aufnahmen mit mindestens einem zwischen einer Lösestellung und einer Verriegelungsstellung bewegbaren Verriegelungselement zur lösbaren Halterung eines zweiten Kopplungselements aufweist.Such quick-change systems are used for easy and convenient changing of different attachments on construction machines. With such quick-change systems, e.g. swivel buckets, grabs, shears, compactors, magnets, hydraulic hammers or other attachments can be coupled or uncoupled in a few seconds and with a high safety standard from a driver's cab, e.g. They usually contain an adapter on the attachment side and a quick coupler arranged on the construction machine, which has, for example, jaw-shaped first receptacles on one side for retaining a first coupling element and on the other side second receptacles with at least one locking element that can be moved between a release position and a locking position for releasable retaining having a second coupling element.

Aus der DE 20 2017 103 198 U1 ist ein Adapter für ein derartiges Schnellwechselsystem bekannt. Dieser weist zur Verbindung des Adapters mit einem Schnellwechsler auf. An einem der beiden bolzenförmigen Kopplungselemente ist ein Kupplungselementträger zur Halterung von adapterseitigen Kupplungselementen für eine Kupplung mit schnellwechlserseitigen Kupplungselementen befestigt. Hierzu sind an einem der beiden bolzenförmigen Kopplungselemente mit Aufnahmebohrungen für Schrauben versehene Anschlussstege angeschweißt. An diese Anschlussstege kann eine mit Öffnungen für die Kupplungselemente versehene Halterung des Kupplungselementträgers über mit der Halterung verschweißte Haltestege angeschraubt werden. Die Befestigung der Anschlussstege an dem bolzenförmigen Kopplungselement und die Befestigung der Haltestege an der Halterung erfolgt über Schweißverbindungen, was mit einem erheblichen fertigungstechnischen Aufwand verbunden ist.From the DE 20 2017 103 198 U1 an adapter for such a quick-change system is known. This has to connect the adapter with a quick coupler. A coupling element carrier for holding adapter-side coupling elements for a coupling with quick-change coupling elements is fastened to one of the two bolt-shaped coupling elements. For this purpose, connecting webs provided with mounting holes for screws are welded to one of the two bolt-shaped coupling elements. A holder of the coupling element carrier provided with openings for the coupling elements can be screwed onto these connecting webs via holding webs welded to the holder. The attachment of the connecting webs to the bolt-shaped coupling element and the attachment of the retaining webs to the bracket is done via welded joints, which is associated with a significant manufacturing effort.

Aufgabe der Erfindung ist es, einen Adapter und ein Schnellwechselsystem mit einem derartigen Adapter zu schaffen, die eine vereinfachte Befestigung des Kupplungselementträgers ermöglichen.The object of the invention is to create an adapter and a quick-change system with such an adapter that allow a simplified attachment of the coupling element carrier.

Diese Aufgabe wird durch einen Adapter mit den Merkmalen des Anspruchs 1 und durch ein Schnellwechselsystem mit den Merkmalen des Anspruchs 13 gelöst. Zweckmäßige Ausgestaltungen und vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by an adapter with the features of claim 1 and by a quick-change system with the features of claim 13. Expedient configurations and advantageous developments of the invention are specified in the dependent claims.

Bei dem erfindungsgemäßen Adapter ist der Kupplungselementträger über eine lösbare Formschlussverbindung gegen Verdrehung gesichert unmittelbar mit dem bolzenförmigen Kopplungselement verbunden und kann z.B. über Schrauben oder andere Befestigungselemente lösbar an dem Kopplungselement befestigt sein. Dadurch kann auch ohne aufwändig am Kopplungselement befestigbare Anschlusselemente eine gegen Verdrehung gesicherte und bei Bedarf einfach lösbare Verbindung zwischen dem Kopplungselement und dem Kupplungselementträger geschaffen werden. Bei eventuellen Beschädigungen des Kupplungselementträgers kann dieser somit auch ohne aufwändige Ausrichtarbeiten einfach ausgetauscht werden. Über die Schrauben kann so z.B. ein Kraftschluss zwischen dem Kupplungselementträger und dem Kopplungselement erreicht werden, während die Formschlussverbindung für die exakte Ausrichtung und gegen Verdrehung gesicherte Halterung sorgt. Auch bei eventuellen Änderungen oder Anpassungen am Kupplungselementträger kann dieser einfach demontiert und gegen einen entsprechend modifizierten Kupplungselementträger ersetzt werden.In the adapter according to the invention, the coupling element carrier is connected directly to the bolt-shaped coupling element via a releasable form-fitting connection, secured against rotation, and can be releasably attached to the coupling element, e.g. using screws or other fastening elements. As a result, a connection between the coupling element and the coupling element carrier that is secured against rotation and can be easily released if necessary can also be created without connection elements that can be attached to the coupling element in a complex manner. In the event of any damage to the coupling element carrier, it can therefore be easily replaced without any time-consuming alignment work. For example, the screws can be used to achieve a frictional connection between the coupling element carrier and the coupling element, while the form-fitting connection ensures exact alignment and a holder that is secured against twisting. Even if there are any changes or adjustments to the coupling element carrier, it can simply be dismantled and replaced with a correspondingly modified coupling element carrier.

In einer fertigungstechnisch besonders vorteilhaften Ausführung kann die Formschlussverbindung zwischen dem Kupplungselementträger und dem Kopplungselement durch eine in das Kopplungselement eingearbeitete Formschlusskontur und eine entsprechende Gegenkontur an dem Kupplungselementträger gebildet sein.In an embodiment that is particularly advantageous in terms of production technology, the form-fitting connection between the coupling element carrier and the coupling element can be formed by a form-fitting contour worked into the coupling element and a corresponding counter-contour on the coupling element carrier.

Zweckmäßigerweise kann die Formschlusskontur am Kopplungselement durch mehrere nutförmige Vertiefungen mit unterschiedlichen Anlageflächen gebildet sein. Die nutförmigen Vertiefungen können mit unterschiedlich geneigten Anlageflächen in die Außenseite des Kopplungselements eingearbeitet sein.The form-fitting contour on the coupling element can expediently be formed by a plurality of groove-shaped indentations with different contact surfaces. The groove-shaped depressions can be worked into the outside of the coupling element with differently inclined contact surfaces.

Die zur Formschlusskontur am Kopplungselement passende Gegenkontur am Kupplungselementträger kann in zweckmäßiger Weise an seitlich vorstehenden gabelförmigen Haltestegen des Kupplungselementträgers angeordnet sein. Die Haltestege können an einer mit Aufnahmen für Kupplungselemente versehenen leistenförmigen Halterung angeordnet sein. Vorzugsweise können die Haltestege einteilig mit der leistenförmigen Halterung ausgebildet sein. Die Gegenkontur kann in bevorzugter Weise durch unterschiedlich geneigte Gegenflächen an der Innenseite einer gabelförmigen Aussparung gebildet sein.The mating contour on the coupling element carrier that matches the form-fitting contour on the coupling element can be arranged expediently on laterally protruding fork-shaped holding webs of the coupling element carrier. The holding webs can be arranged on a strip-shaped holder provided with receptacles for coupling elements. The holding webs can preferably be formed in one piece with the strip-shaped holder. The counter-contour can preferably be formed by differently inclined counter-surfaces on the inside of a fork-shaped recess.

Zur sicheren und positionsgenauen Halterung des mit dem Kupplungselementträger versehenen Kopplungselements an den Seitenwangen ist das Kopplungselement zweckmäßigerweise gegen Verdrehung gesichert an den Seitenwangen befestigt. Hierzu kann die Verbindung zwischen dem Kopplungselement und den Seitenwangen z.B. über eine Formschlussverbindung mit einer speziellen Kontur an dem Kopplungselement und einer dazu passenden Gegenkontur an mindestens einer Seitenwange erfolgen.In order to hold the coupling element provided with the coupling element carrier securely and in the exact position on the side walls, the coupling element is expediently secured against rotation on the side walls. For this purpose, the connection between the coupling element and the side walls can be made, for example, via a positive connection with a special contour on the coupling element and a matching counter-contour on at least one side wall.

In einer weiteren zweckmäßigen Ausgestaltung kann der Kupplungselementträger durch Schrauben kraftschlüssig an dem bolzenförmigen Kopplungselement befestigt sein. Die Schrauben können z.B. durch Querbohrungen im bolzenförmigen Kopplungselement in Gewindebohrungen am Kupplungselementträger eingreifen.In a further expedient embodiment, the coupling element carrier can be fastened to the bolt-shaped coupling element in a non-positive manner by means of screws. The screws can, for example, engage in threaded holes on the coupling element carrier through transverse bores in the bolt-shaped coupling element.

Die Erfindung betrifft außerdem ein Schnellwechselsystem mit einem vorstehend beschriebenen Adapter und einem mit dem Adapter kuppelbaren Schnellwechsler zum einfachen Wechseln eines Anbaugeräts an Fahrzeugen.The invention also relates to a quick-change system with an adapter described above and a quick-change device that can be coupled to the adapter for easy changing of an attachment on vehicles.

In den Figuren 1 und 2 ist ein aus einem Adapter 1 und einem zugehörigen Schnellwechsler 2 bestehendes Schnellwechselsystem zum einfachen Wechseln eines nur zum Teil dargestellten Anbaugeräts 3 an Fahrzeugen, insbesondere Baumaschinen, in einer noch getrennten Stellung (Figur 1) und einer angekuppelten Stellung (Figur 2) gezeigt. Mit einem derartigen Schnellwechselsystem können z.B. Schwenklöffel, Greifer, Scheren, Magnete, Verdichter, Hydraulikhammer oder andere mechanische bzw. hydraulische Anbaugeräte einfach und bequem von einer Fahrerkabine aus an einem Ausleger oder einem anderen Anbauteil eines Baufahrzeugs an- bzw. abgekuppelt werden.In the Figures 1 and 2 is a quick-change system consisting of an adapter 1 and an associated quick-change device 2 for easy changing of an attachment 3, which is only partially shown, on vehicles, in particular construction machines, in a still separate position ( figure 1 ) and a coupled position ( figure 2 ) shown. With such a quick-change system, swivel buckets, grippers, shears, magnets, compactors, hydraulic hammers or other mechanical or hydraulic attachments can be easily and conveniently coupled to or decoupled from a driver's cab on a boom or other attachment of a construction vehicle.

Der an dem Anbaugerät 3 angeordnete Adapter 1 enthält zwei zueinander parallele, voneinander beabstandete Seitenwangen 4, zwischen denen ein erstes bolzenförmiges Kopplungselement 5 und ein davon in einem vorgegebenen Abstand angeordnetes zweites bolzenförmiges Kopplungselement 6 zur lösbaren Verbindung mit der Schnellwechsler 2 gehalten sind. Die beiden zueinander parallelen bolzenförmigen Kopplungselemente 5 und 6 sind in entsprechende Öffnungen 7 bzw. 8 in den beiden Seitenwangen 4 des Adapters 1 eingesteckt und dort fixiert.The adapter 1 arranged on the attachment 3 contains two mutually parallel side walls 4 spaced apart from one another, between which a first bolt-shaped coupling element 5 and a second bolt-shaped coupling element 6 arranged at a predetermined distance therefrom are held for the detachable connection to the quick coupler 2. The two parallel bolt-shaped coupling elements 5 and 6 are inserted into corresponding openings 7 and 8 in the two side panels 4 of the adapter 1 and fixed there.

Der z.B. an einem Ausleger eines Baggers montierbare Schnellwechsler 2 enthält an der einen Seite nach vorne offene, gabel- oder maulförmige erste Aufnahmen 9 zur Aufnahme und Halterung des ersten bolzenförmigen Kopplungselements 5 und an der anderen Seite nach unten offene zweite Aufnahmen 10 mit einem in Figur 2 gezeigten beweglichen Verriegelungselement 11 zur Aufnahme und Halterung des zweiten bolzenförmigen Kopplungselements 6. Die nach unten offenen Aufnahmen 10 weisen eine gekrümmte Anlagefläche 12 zur Anlage des zweiten bolzenförmigen Kopplungselements 6 auf.The quick coupler 2, which can be mounted, for example, on a boom of an excavator, contains, on one side, open, fork-shaped or jaw-shaped first receptacles 9 for receiving and holding the first bolt-shaped coupling element 5, and on the other side, second receptacles 10 open downwards with a figure 2 movable locking element 11 shown for receiving and holding the second bolt-shaped Coupling element 6. The receptacles 10, which are open at the bottom, have a curved contact surface 12 for contacting the second bolt-shaped coupling element 6.

In der gezeigten Ausführung enthält der Schnellwechsler 2 einen Träger 13, der an einer Seite zwei gabel- oder maulförmige Aufnahmen 9 für das erste Kopplungselement 5 und auf der anderen Seite zwei Aufnahmen 10 für das zweite Kopplungselement 6 enthält. An zwei an der Oberseite des Trägers 13 angeordneten parallelen Seitenteilen 14 sind außerdem durchgängige Aufnahmeöffnungen 15 für nicht dargestellte Befestigungsbolzen zur Befestigung des Schnellwechslers 2 an einem Ausleger eines Baggers oder einem Anschlussteil eines anderen Baufahrzeugs vorgesehen.In the embodiment shown, the quick coupler 2 contains a carrier 13 which contains two fork-shaped or jaw-shaped receptacles 9 for the first coupling element 5 on one side and two receptacles 10 for the second coupling element 6 on the other side. In addition, continuous receiving openings 15 for fastening bolts (not shown) for fastening the quick coupler 2 to a boom of an excavator or a connection part of another construction vehicle are provided on two parallel side parts 14 arranged on the upper side of the carrier 13 .

In zwei hier als Führungsbohrungen im Träger 13 ausgebildeten, parallelen Führungen des Schnellwechslers 2 sind die bei der gezeigten Ausführung als Verriegelungsbolzen ausgebildeten Verriegelungselemente 11 hydraulisch zwischen einer in Figur 1 gezeigten eingezogenen Lösestellung und einer in Figur 2 dargestellten ausgefahrenen Verriegelungsstellung verschiebbar angeordnet. In der ausgefahrenen Verriegelungsstellung werden die nach unten offenen zweiten Aufnahmen 10 von den bolzenförmigen Verriegelungselementen 11 an der Unterseite geschlossen, so dass das zweite bolzenförmige Kopplungselement 6 von dem Verriegelungselement 11 untergriffen wird und der Adapter 1 am Schnellwechsler 2 gehalten werden kann.In two parallel guides of the quick coupler 2, designed here as guide bores in the carrier 13, the locking elements 11, designed as locking bolts in the embodiment shown, are hydraulically connected between an in figure 1 retracted release position shown and a in figure 2 shown extended locking position slidably arranged. In the extended locking position, the second receptacles 10, which are open at the bottom, are closed by the bolt-shaped locking elements 11 on the underside, so that the locking element 11 reaches under the second bolt-shaped coupling element 6 and the adapter 1 can be held on the quick coupler 2.

Um den Adapter 1 an dem Schnellwechsler 2 anzukuppeln, wird der in der Regel an einem Ausleger eines Baggers angeordnete Schnellwechsler 2 zunächst so bewegt, dass das erste bolzenförmige Kopplungselement 6 am Adapter 1 in die maulförmigen Aufnahmen 10 auf der einen Seite des Schnellwechslers 2 eingefahren wird. Dann wird der Schnellwechsler 2 mit noch zurückgezogenen Verriegelungselementen 11 um das erste bolzenförmige Kopplungselement 5 so geschwenkt, dass das zweite bolzenförmige Kopplungselement 6 am Adapter 1 zur Anlage an den Anlageflächen 12 der nach unten offenen Aufnahmen 10 auf der anderen Seite des Schnellwechslers 2 gelangt. Anschließend können die in dem Träger 13 des Schnellwechslers 2 verschiebbar angeordneten, bolzenförmigen Verriegelungselemente 11 gemäß Figur 2 hydraulisch ausgefahren werden, so dass das zweite bolzenförmige Kopplungselement 7 am Adapter 1 von den beiden bolzenförmigen Verriegelungselementen 11 an dem Schnellwechsler 2 untergriffen und der Adapter 1 somit an dem Schnellwechsler 2 gehalten wird.In order to couple the adapter 1 to the quick coupler 2, the quick coupler 2, which is usually arranged on a boom of an excavator, is first moved in such a way that the first bolt-shaped coupling element 6 on the adapter 1 is moved into the jaw-shaped receptacles 10 on one side of the quick coupler 2 . Then, with the locking elements 11 still pulled back, the quick coupler 2 is pivoted about the first bolt-shaped coupling element 5 in such a way that the second bolt-shaped coupling element 6 on the adapter 1 comes to rest on the contact surfaces 12 of the receptacles 10, which are open at the bottom, on the other side of the quick coupler 2. Then the in the carrier 13 of the quick coupler 2 slidably arranged, bolt-shaped locking elements 11 according to figure 2 be extended hydraulically, so that the second bolt-shaped coupling element 7 on the adapter 1 is gripped by the two bolt-shaped locking elements 11 on the quick coupler 2 and the adapter 1 is thus held on the quick coupler 2 .

Wie aus den Figuren 3 und 4 hervorgeht, ist an dem zweiten bolzenförmigen Kopplungselement 6 des Adapters 1 ein Kupplungselementträger 16 zur Halterung von adapterseitigen Kupplungselementen für eine Kupplung mit schnellwechslerseitigen Kupplungselementen 2 lösbar befestigt. Über die an Kupplungselementträger 16 angeordneten - nicht dargestellten - adapterseitigen Kupplungselemente können zur Energieversorgung des Anbaugeräts 3 am Adapter 1 vorgesehene Energieanschlüsse beim Ankoppeln des Adapters 1 an den Schnellwechsler 2 automatisch mit entsprechenden Energieversorgungsleitungen am Schnellwechsler 2 verbunden werden. Dadurch kann das Anbaugerät 3 z.B. mit Hydraulikfluid, elektrischer Energie oder einem anderen Energieträger versorgt werden.How from the Figures 3 and 4 As can be seen, a coupling element carrier 16 for holding adapter-side coupling elements for a coupling with quick coupler-side coupling elements 2 is releasably attached to the second bolt-shaped coupling element 6 of the adapter 1 . The adapter-side coupling elements (not shown) arranged on the coupling element carrier 16 can be used to automatically connect energy connections provided on the adapter 1 with corresponding energy supply lines on the quick coupler 2 to supply energy to the attachment 3 when coupling the adapter 1 to the quick coupler 2 . As a result, the attachment 3 can be supplied with hydraulic fluid, electrical energy or another energy source, for example.

Der Kupplungselementträger 16 weist eine mit lochförmigen Aufnahmen 17 für Kupplungselemente versehene, parallel zum Kopplungselement 6 angeordnete leistenförmige Halterung 18 mit an dieser angeordneten Haltestegen 19 und 20 zur lösbaren Verbindung mit dem bolzenförmigen Kopplungselement 6 auf. Bei der gezeigten Ausführung sind an der leistenförmigen Halterung 18 zwei gabelförmige äußere Haltestege 19 und ein gabelförmiger innerer Haltesteg 20 angeordnet. Über die das Kopplungselement 6 übergreifenden gabelförmigen Haltestege 19 und 20 ist der Kupplungselementträger 16 durch Schrauben 21 kraftschlüssig an dem Kopplungselement 6 befestigt. Die Schrauben 21 greifen durch Querbohrungen 22 im Kopplungselement in Gewindebohrungen 23 der Haltestege 19 und 20 ein. Für eine gegen Verdrehung gesicherte Halterung des bolzenförmigen Kopplungselements 6 gegenüber den Seitenwangen 4 weist das Kopplungselement 6 an mindestens einem Ende gegenüberliegende Abflachungen 24 zum Eingriff mit korrespondierenden Gegenflächen 25 an der entsprechenden Öffnung 8 in der Seitenwange 4 auf.The coupling element carrier 16 has a strip-shaped holder 18 , which is provided with hole-shaped receptacles 17 for coupling elements and is arranged parallel to the coupling element 6 , with holding webs 19 and 20 arranged thereon for the detachable connection to the bolt-shaped coupling element 6 . In the embodiment shown, two forked outer holding webs 19 and a forked inner holding web 20 are arranged on the strip-shaped holder 18 . The coupling element carrier 16 is non-positively fastened to the coupling element 6 by means of screws 21 via the fork-shaped holding webs 19 and 20 that overlap the coupling element 6 . The screws 21 engage in threaded bores 23 of the holding webs 19 and 20 through transverse bores 22 in the coupling element. To secure the bolt-shaped coupling element 6 against rotation relative to the side walls 4 , the coupling element 6 has opposite flattened areas 24 on at least one end for engagement with corresponding mating surfaces 25 on the corresponding opening 8 in the side wall 4 .

Aus den Figuren 5 und 6 ist ersichtlich, dass das bolzenförmige Kopplungselement 6 an seiner Außenseite eine eingearbeitete Formschlusskontur 26 zum formschlüssigen Eingriff mit einer entsprechenden Gegenkontur 27 an den gegenüber der Halterung 18 vorstehenden, gabelförmigen Haltestegen 19 und 20 des Kupplungselementträgers 16 enthält. In dem gezeigten Ausführungsbeispiel wird die als Außenkontur mit Vertiefungen ausgeführte Formschlusskontur 26 am Kopplungselement 6 durch mehrere auch in Figur 3 erkennbare nutförmige Vertiefungen 28, 29 und 30 gebildet, die mit unterschiedlichen Winkeln in die Außenseite des bolzenförmigen Kopplungselements 6 eingearbeitet sind und unterschiedlich geneigte Anlageflächen 31, 32 und 33 zur Anlage an entsprechenden Gegenflächen 34, 35 und 36 des Kupplungselementträgers 16 bilden. Die Gegenflächen 34, 35 und 36 sind an der Innenseite einer gabelförmigen Aussparung 37 an den seitlich vorstehenden Haltestegen 19 und 20 des Kupplungselementträgers 16 vorgesehen.From the Figures 5 and 6 It can be seen that the bolt-shaped coupling element 6 has an incorporated positive-locking contour 26 on its outside for positive-locking engagement with a corresponding counter-contour 27 on the fork-shaped retaining webs 19 and 20 of the coupling element carrier 16 that protrude in relation to the holder 18 . In the exemplary embodiment shown, the form-fitting contour 26, designed as an outer contour with indentations, on the coupling element 6 is also figure 3 recognizable groove-shaped depressions 28, 29 and 30 formed, which are incorporated at different angles in the outside of the bolt-shaped coupling element 6 and different inclined contact surfaces 31, 32 and 33 for contact with corresponding mating surfaces 34, 35 and 36 of the coupling element carrier 16 form. The mating surfaces 34, 35 and 36 are provided on the inside of a fork-shaped recess 37 on the laterally projecting holding webs 19 and 20 of the coupling element carrier 16.
