Description

Die Erfindung betrifft einen Gleitrahmen mit Kolben-Verschwenkeinrichtung, insbesondere für einen Seitenschieber-Löffelbagger, wobei der Gleitrahmen eine zum verschiebbaren Übergreifen entsprechend ausgebildeter Gleitschienen bestimmte obere und untere Gleitschienen-Übergreiffläche aufweist, zwischen denen ein paralleler oberer und ein paralleler unterer Querträger angeordnet sind, in denen dazwischen liegende und sich senkrecht zur Gleitrahmenebene erstreckende hydraulische Verschwenkzylinder gelagert sind, die sich um Vertikalachsen in einer Horizontalebene verschwenken lassen.The invention relates to a slide frame with a piston pivoting device, in particular for a side-shovel backhoe, the slide frame having an upper and lower slide rail overlap surface, which is designed for slidably gripping over correspondingly designed slide rails, between which a parallel upper and a parallel lower cross member are arranged in which hydraulic pivoting cylinders lying in between and extending perpendicular to the plane of the sliding frame are mounted and can be pivoted about vertical axes in a horizontal plane.

Eine derartige Ausführungsform läßt sich der US-Patentschrift 4,039,095 entnehmen. Offenbart ist hier ein Traktor, an dessen Rückseite ein Seitenschieber-Löffelbagger montiert ist. Die Befestigung erfolgt über einen Tragrahmen mit einer oberen und unteren, quer zum Traktor verlaufenden Gleitschiene, auf denen ein Gleitrahmen seitenverschieblich angeordnet ist. Durch eine Blockiereinrichtung kann der Gleitrahmen in der jeweils gewünschten Verschiebestellung am Tragrahmen bzw. an dessen Gleitschienen arretiert werden. An der rückwärtigen Seite des Gleitrahmens ist ein Schwingrahmen verschwenkbar gelagert, der um eine Vertikalachse in einer Horizontalebene verschwenkt wird. Hierfür sind zwei übereinander liegende und sich senkrecht zur Gleitrahmenebene erstreckende hydraulische Schwenkzylinder vorgesehen, die mit oberen und unteren, miteinander fluchtenden Vertikalzapfen in entsprechende Lagerbohrungen von Querträgern des Gleitrahmens eingreifen. Das jeweils freie Ende der Kolbenstangen dieser beiden Verschwenkzylinder ist am Schwingrahmen angelenkt, der durch Einziehen. bzw. Ausfahren der Kolbenstangen nach links oder rechts verschwenkt werden kann. Die obere Gleitschiene aufliegenden Horizontalplatte, gegen deren vordere Stirnkante eine nach unten ragende Leiste geschraubt ist, die die obere Gleitschiene hintergreift. Die untere Gleitschienen-Übergreiffläche wird ebenfalls durch eine gegen die vordere Stirnkante einer unteren Horizontalplatte geschraubte Leiste gebildet, die nach oben ragt und eine untere Gleit- bzw. Führungsschiene hintergreift.Such an embodiment can be found in US Pat. No. 4,039,095. A tractor is disclosed here, on the back of which a side-shift backhoe is mounted. It is attached using a support frame with an upper and lower slide rail that runs across the tractor and on which a slide frame is arranged so that it can be moved laterally. The sliding frame can be locked in the desired displacement position on the supporting frame or on its sliding rails by a blocking device. On the rear side of the slide frame, a swing frame is pivotally mounted, which is pivoted about a vertical axis in a horizontal plane. For this purpose, two hydraulic swivel cylinders lying one above the other and extending perpendicular to the plane of the slide frame are provided, which engage with corresponding vertical bores in corresponding bearing bores of cross members of the slide frame with upper and lower vertical pins aligned with one another. The free end of the piston rods of these two swivel cylinders is articulated on the swing frame, which is pulled in. or extending the piston rods can be pivoted to the left or right. The upper slide rail is supported by a horizontal plate, against the front end edge of which a downwardly projecting strip is screwed, which engages behind the upper slide rail. The lower slide rail overlapping surface is also formed by a strip screwed against the front end edge of a lower horizontal plate, which projects upwards and engages behind a lower slide or guide rail.

Bei dieser vorbekannten Ausführungsform bilden die Querträger, zwischen denen die beiden Verschwenkzylinder gelagert sind, einen integralen Bestandteil des Gleitrahmens. Die Lagerung der Verschwenkzylinder zwischen den Querträgern liegt noch vor den Gleitschienen, wobei die Begriffe « vorn bzw. « hinten auf den Traktor bezogen sind, an dessen Rückseite das genannte Gerät montiert ist. Die Montage bzw. Demontage der Verschwenkzylinder ist wegen zahlreicher anderer, die Handhabung erschwerenden Bauteile schwierig.In this known embodiment, the cross members, between which the two pivoting cylinders are mounted, form an integral part of the slide frame. The pivoting cylinders are mounted between the cross members in front of the slide rails, whereby the terms "front and" rear refer to the tractor, on the rear of which the device mentioned is mounted. The assembly or disassembly of the pivoting cylinder is difficult because of numerous other components that complicate handling.

Der Erfindung liegt somit die Aufgabe zugrunde, den eingangs erläuterten Gleitrahmen hinsichtlich der Montage bzw. Demontage einzelner Bauteile zu verbessern.The invention is therefore based on the object of improving the sliding frame explained at the outset with regard to the assembly and disassembly of individual components.

Diese Aufgabe wird gemäß der Erfindung durch folgende Merkmale gelöst :

  • a) zwischen der oberen und unteren Gleitschienen-Übergreiffläche ist im Gleitrahmen eine angenähert rechteckige Durchtrittsöffnung vorgesehen ;
  • b) die genannten Querträger sind oberhalb und unterhalb dieser Durchtrittsöffnung mit lösbaren Befestigungsmitteln am Gleitrahmen abnehmbar montiert;
  • c) die beiden Verschwenkzylinder sind nebeneinander angeordnet und erstrecken sich durch die Durchtrittsöffnung hindurch.
This object is achieved according to the invention by the following features:
  • a) an approximately rectangular passage opening is provided in the slide frame between the upper and lower slide rail overlap surface;
  • b) said cross members are detachably mounted above and below this passage opening with releasable fastening means on the slide frame;
  • c) the two pivoting cylinders are arranged next to one another and extend through the passage opening.

Dabei ist es zweckmäßig, wenn zur Aufnahme der Querträger unmittelbar oberhalb und unterhalb der Durchtrittsöffnung je eine zur Frontseite des Gleitrahmens offene Ausnehmung vorgesehen ist, die eine obere und untere Vertikalfläche bilden, an denen die Querträger von den Befestigungsmitteln gehalten sind.It is useful if a recess open to the front of the slide frame is provided for receiving the cross members immediately above and below the passage opening, which form an upper and lower vertical surface on which the cross members are held by the fastening means.

Dabei können die Verschwenkzylinder mit oberen und unteren, miteinander fluchtenden Vertikalzapfen in entsprechende Lagerbohrungen der Querträger eingreifen.The swivel cylinders can engage with corresponding vertical bores of the crossbeams with upper and lower vertical pins that are aligned with one another.

Bei der neuen Konstruktion sind somit die Verschwenkzylinder ausschließlich an den beiden Querträgern gelagert, so daß diese Montage außerhalb der eigentlichen Vorrichtung ohne Behinderung durch andere Bauteile vorgenommen werden kann. Die aus den Querträgern und den Verschwenkzylindern bestehende Baugruppe läßt sich dann in besonders einfacher und schneller Weise am Gleitrahmen montieren, wobei die Festlegung vorzugsweise durch Schraubbolzen erfolgt. Letztere können von der Rückseite des Gleitrahmens in den Bereich der genannten Vertikalflächen gesteckt werden, was sich einfach durchführen läßt, da die Rückseite frei zugänglich ist.In the new design, the pivoting cylinders are thus mounted exclusively on the two cross members, so that this assembly can be carried out outside the actual device without being hindered by other components. The assembly consisting of the cross members and the pivoting cylinders can then be mounted on the slide frame in a particularly simple and quick manner, the fixing preferably being carried out by means of screw bolts. The latter can be inserted from the back of the slide frame in the area of the vertical surfaces mentioned, which can be carried out easily because the back is freely accessible.

Weiterhin kann es zweckmäßig sein, wenn die obere Gleitschienen-Übergreiffläche teilzylindrisch ausgebildet und nach unten offen ist, während die untere Gleitschienen-Übergreiffläche durch eine nach vorn und oben gebogene Anschlagschiene gebildet wird, die über Befestigungsmittel lösbar am Gleitrahmen montiert ist.Furthermore, it may be expedient if the upper slide rail overlapping surface is partially cylindrical and is open at the bottom, while the lower slide rail overlapping surface is formed by a stop rail bent forward and upward, which is detachably mounted on the slide frame via fastening means.

Der Gleitrahmen hängt somit auf der oberen Gleitschiene, aus der er dann in einfacher Weise ausgehängt werden kann, wenn die untere Anschlagschiene vom Gleitrahmen abgeschraubt wird.The slide frame thus hangs on the upper slide rail, from which it can be easily removed when the lower stop rail is unscrewed from the slide frame.

Zum Stand der Technik kann insoweit noch auf die US-Patenschrift 3,614,134 verwiesen werden.As far as the state of the art is concerned, reference can be made to US Pat. No. 3,614,134.

In der Zeichnung ist eine als Beispiel dienende Ausführungsform der Erfindung dargestellt. Es zeigen :

  • Figur 1 in perspektivischer Darstellung die rechte Rückseite eines Traktors mit angebautem Löffelbagger;
  • Figur 2 in vergrößertem Maßstab im Ausschnitt eine rechte Seitenansicht eines Trag- und Gleitrahmens und
  • Figur 3 in perspektivischer Darstellung un im Ausschnitt die Vorderseite des Gleitrahmens gemäß Figur 2.
In the drawing, an exemplary embodiment of the invention is shown. Show it :
  • Figure 1 is a perspective view of the right rear of a tractor with a backhoe attached;
  • Figure 2 on an enlarged scale cut a right side view of a support and slide frame and
  • 3 shows a perspective view and a detail of the front of the slide frame according to FIG. 2.

Figur 1 zeigt einen Seitenschieber-Löffelbagger 10, der an der Rückseite eines Traktors 12 montiert ist. Die genannte Vorrichtung umfaßt einen sich quer über die Rückseite des Traktors erstreckenden Tragrahmen 14, der eine obere Gleitschiene 16 (siehe Figur 2) mit angenähert halbzylindrischer oberer Gleitfläche 17 sowie eine untere Schiene 18 aufweist, die gegen die Unterseite eines Quer-Kastenträgers 20 geschweißt ist. Die untere Schiene 18 weist eine vordere, schräg nach unten abfallende Anschlagfläche 21 auf.FIG. 1 shows a side-shift shovel excavator 10 which is mounted on the rear of a tractor 12. Said device comprises a support frame 14 which extends transversely over the rear of the tractor and which has an upper slide rail 16 (see FIG. 2) with an approximately semi-cylindrical upper slide surface 17 and a lower rail 18 which is welded against the underside of a transverse box girder 20 . The lower rail 18 has a front abutment surface 21 that slopes downwards.

Ein Gleitrahmen 22 ist an seinem oberen Ende 24 hakenförmig nach vorn und unten gebogen und bildet so eine nach unten offene Gleitschienen-Übergreiffläche 26, die der runden Oberflächenkontur 17 der oberen Gleitschiene 16 angepaßt ist. Der Gleitrahmen 22 weist ferner ein Mittelstück 28 auf, das mit einer am meisten vorn liegenden, angenähert planen Frontseite 30 versehen ist, gegen deren unteren Bereich mit Schraubbolzen 31 eine Anschlagschiene 32 geschraubt ist. Letztere verläuft parallel zur unteren Schiene 18 des Tragrahmens 14, ist nach vorn und oben gebogen und bildet eine etwas ballig ausgebildete, schräg nach oben verlaufende und nach hinten zeigende Gleitschienen-Übergreiffläche 34, die der Anschlagfläche 21 der unteren Schiene 18 zugeordnet ist. Nach dem Abschrauben der Anschlagschiene 32 braucht der Gleitrahmen 22 lediglich nach oben aus der oberen Gleitschiene 16 Tragrahmens 14 ausgehoben zu werden, um sich vom Tragrahmen abbauen zu lassen. Umgekehrt läßt sich der Gleitrahmen 22 in gleicher Weise sehr einfach montieren, da er lediglich mit seinem hakenförmigen oberen Ende 24 auf die obere Gleitschiene 16 gehängt werden muß. Die Anschlagschiene 32 läßt sich dann schnell und einfach festschrauben.A slide frame 22 is bent at its upper end 24 forward and downward in a hook-like manner and thus forms a downwardly open slide rail overlap surface 26 which is adapted to the round surface contour 17 of the upper slide rail 16. The sliding frame 22 also has a center piece 28, which is provided with a most front, approximately flat front side 30, against the lower region of which a stop rail 32 is screwed with bolts 31. The latter runs parallel to the lower rail 18 of the support frame 14, is bent forward and upward and forms a somewhat spherical, sloping upward and rearward-pointing slide rail overlap surface 34 which is assigned to the stop surface 21 of the lower rail 18. After unscrewing the stop rail 32, the slide frame 22 only needs to be lifted upward out of the upper slide rail 16 support frame 14 in order to be removed from the support frame. Conversely, the slide frame 22 can be assembled very easily in the same way, since it only has to be hung on the upper slide rail 16 with its hook-shaped upper end 24. The stop rail 32 can then be screwed on quickly and easily.

Im Mittelstück 28 des Gleitrahmens 22 sind links und rechts je eine Zylinderbohrung 36 vorgesehen (siehe insbesondere Figur 3), in denen doppelt wirkende Hydraulikkolben 38 angeordnet sind, die sich beim Ausfahren nach vorn teilweise gegen die Rückseite 40 des Quer-Kastenträgers 20 und teilweise gegen die Rückseite 42 der unteren Schiene 18 anlegen. Wird Flüssigkeitsdruck in die Zylinderbohrungen 36 rückseitig der Kolben 38 eingelassen, legen sich die Kolben 38 gegen die genannten Rückflächen 40, 42 an und verschwenken dadurch den Gleitrahmen 22 im Uhrzeigersinn um die Gleitfläche 17 der oberen Gleitschiene 16. Dadurch legt sich die Gleitschienen-Übergreiffläche 34 der Anschlagschiene 32 gegen die Anschlagfläche 21 an, deren Neigung aufgrund der von de, Kolben 38 ausgeübten Kraft eine nach unten gerichtete Kraftkomponente bewirkt, die zu einem hohen Kraftschluß zwischen der oberen Aufnahme 26 des Gleitrahmens und der oberen Gleitschiene 16 führt, so daß der Gleitrahmen 22 hinsichtlich einer seitlichen Verschiebung blockiert ist.In the center piece 28 of the slide frame 22, a cylinder bore 36 is provided on the left and right (see in particular FIG. 3), in which double-acting hydraulic pistons 38 are arranged, which partially extend against the rear side 40 of the cross-member beam 20 and partially against when extending forward create the back 42 of the lower rail 18. If liquid pressure is admitted into the cylinder bores 36 on the rear side of the pistons 38, the pistons 38 bear against the mentioned rear surfaces 40, 42 and thereby pivot the slide frame 22 clockwise around the slide surface 17 of the upper slide rail 16. As a result, the slide rail overlap surface 34 lies down the stop rail 32 against the stop surface 21, the inclination of which, due to the force exerted by the piston 38, causes a downward force component, which leads to a high frictional connection between the upper receptacle 26 of the slide frame and the upper slide rail 16, so that the slide frame 22 is blocked with respect to a lateral displacement.

Im Mittelstück 28 des Gleitrahmens 22 ist eine verhältnismäßig große, angenähert rechteckige Durchtrittsöffnung 44 vorgesehen, die nach vorn und hinten offen ist und an ihrem oberen sowie unteren Rand jeweils von Ausnehmung begrenzt wird, die jeweils zur Frontseite 30 des Gleitrahmens 22 offen sind une eine obere und untere, jeweils nach vorn weisende Vertikalfläche 46, 48 bilden. An diesen Vertikalflächen 46, 48 sind über obere und untere Bolzen 50, 52 ein oberer sowie ein unterer Querträger 54, 56 lösbar befestigt, die einen angenähert rechteckigen Querschnitt aufweisen. Der in Figur 3 dargestellte obere Querträger 54 weist eine rechte und linke Lagerbohrung 58, 60 auf, die mit entsprechenden Bohrungen des unteren Querträgers 56 fluchten, wobei von diesen Bohrungen jedoch nur die linke Bohrung 64 in Figur 2 angedeutet ist. Eine rechte, linear wirkende hydraulische Verschwenkeinrichtung 66 weist einen Zylinder 68 auf, der mit einem nicht dargestellten oberen und unteren Vertikalzapfen verschwenkbar in die genannten Lagerbohrungen 58 der Querträger 54, 56 eingreifen. In gleicher Weise umfaßt auch die linke, linear wirkende hydraulische Verstelleinrichtung 74 einen Zylinder 76, der mit einem oberen und unteren Vertikalzapfen 78, 80 verschwenkbar in die genannten Lagerbohrungen 60, 64 eingreift. Aus den rückwärtigen Enden der Zylinder 68, 76 ragen Kolbenstangen 82, 84, die unmittelber an mit horizontalem Abstand nebeneinander angeordneten Augen eines Schwingrahmens 90 angelenkt sind, der üner Vertikalachsen 92 verschwenkbar vom Gleitrahmen 22 getragen wird. Werden, bezogen auf Figur 1, die Kolbenstange 82 eingezogen und die Kolbenstange 84 ausgefahren, erfolgt eine Verschwenkung des Schwingrahmens 90 in einer Horizontalebene nach links. Eine entsprechende Rechtsverschwenkung wird durch Einziehen der Kolbenstange 84 und durch Ausfahren der Kolbenstange 82 bewirkt.In the middle piece 28 of the slide frame 22, a relatively large, approximately rectangular passage opening 44 is provided, which is open to the front and rear and is delimited at its upper and lower edges by recesses, which are each open to the front 30 of the slide frame 22 and an upper one and form the lower, forward-facing vertical surface 46, 48. On these vertical surfaces 46, 48, an upper and a lower cross member 54, 56 are releasably attached via upper and lower bolts 50, 52, which have an approximately rectangular cross section. The upper cross member 54 shown in FIG. 3 has a right and left bearing bore 58, 60 which are aligned with corresponding bores of the lower cross member 56, only the left bore 64 being indicated in FIG. 2 of these bores. A right-hand, linearly acting hydraulic pivoting device 66 has a cylinder 68 which, with an upper and lower vertical pin, not shown, pivotably engage in the bearing bores 58 of the crossbeams 54, 56. In the same way, the left, linearly acting hydraulic adjustment device 74 also comprises a cylinder 76, which engages with the upper and lower vertical pins 78, 80 so as to pivot in the bearing bores 60, 64 mentioned. From the rear ends of the cylinders 68, 76 protrude piston rods 82, 84, which are articulated directly to the eyes of a swing frame 90 which are arranged next to one another at a horizontal distance and are pivotally supported by the sliding frame 22 via vertical axes 92. If, with reference to FIG. 1, the piston rod 82 is retracted and the piston rod 84 is extended, the oscillating frame 90 is pivoted to the left in a horizontal plane. A corresponding right pivoting is effected by retracting the piston rod 84 and by extending the piston rod 82.
