Abstract
Description
Die Erfindung betrifft einen teleskopierbaren Schiebeholm, wie er allgemein bei Arbeitsmaschinen, vorzugsweise bei Autokranen oder Bagger anwendbar ist.The invention relates to a telescopic sliding beam, as it is generally applicable to work machines, preferably in mobile cranes or excavators.
Gerade im Bereich der Autokrane oder auch Bagger gibt es eine Vielfalt an hydraulischen Abstützungsmöglichkeiten, die zur Verbesserung der Tragfähigkeit und Standsicherheit dienen. Hier sind beispielsweise einfache teleskopierbare Schiebeholme, doppelt teleskopierbare Schiebeholme, Klappholme oder auch Kombinationen von Klappholmen und Schiebeholmen bekannt.Especially in the field of mobile cranes or excavators, there are a variety of hydraulic support options, which serve to improve the carrying capacity and stability. Here, for example, simple telescopic sliding beams, double telescopic sliding beams, folding arms or combinations of folding beams and sliding beams are known.
Für den sicheren Arbeitsbetrieb sind je nach den örtlichen Gegebenheiten in Abhängigkeit der erforderlichen Tragfähigkeit unterschiedliche Ausfahrzustände der seitlich vom Fahrgestell abgehenden Schiebeholme erforderlich, bei denen die Lasteinleitung in die Schiebeholme aus statischen Gründen über definierte Lasteinleitungsstellen erfolgen muss. Die Lasteinleitungsstellen müssen in allen Ausfahrzuständen jederzeit reproduzierbar angefahren werden können.Depending on the local conditions, depending on the required load capacity, different states of extension of the sliding beams extending laterally from the chassis are required for safe working operation, in which case the load introduction into the sliding beams must be effected via defined load introduction points for static reasons. The load introduction points must be able to be approached at any time reproducibly in all Ausfahrzuständen.
Es ist bereits bekannt, doppelt teleskopierbare Schiebeholme vorzusehen, wobei die Systeme beim Austeleskopieren bzw. Wiedereinfahren der Schiebeholme unterschiedlich aufgebaut sein können. Hier können beispielsweise vorgesehene Hydraulikzylinder und Seilausschubsysteme miteinander kombiniert sein. Anstelle dieser Systeme sind auch Hydraulikzylinder mit Kettenausschub bereits eingesetzt worden. Eine Alternative besteht darin, zwei Hydraulikzylinder, jeweils einen für jeden Schiebeholm, einzusetzen oder aber auch einen einzigen Zweistufenzylinder zu verwenden.It is already known to provide double-telescopic sliding beams, the systems can be constructed differently when Austeleskopieren or re-entry of the sliding beams. Here, for example, provided hydraulic cylinder and Seilausschubsysteme be combined with each other. Instead of these systems, hydraulic cylinders with chain shifter have already been used. An alternative is to use two hydraulic cylinders, one for each sliding beam, or to use a single two-stage cylinder.
Beim bekannten Ausschubsystem mit einem Hydraulikzylinder und einem Seil- bzw. Kettenausschub erfolgt der Teleskopiervorgang der Schiebeholme wie folgt:
- Zunächst wird der erste Schiebeholm mittels eines hydraulischen Zylinders zwischen Schiebeholmkasten und Schiebeholm ausgeschoben. Der Ausschub vom zweiten Schiebeholm erfolgt synchron, da dieser mechanisch mit dem ersten Schiebeholm über ein Flaschenzugsystem aus Seilen bzw. Ketten verbunden ist. Grundsätzlich ist durch die mechanische Verbindung von beiden Schiebeholmen und die fixe Länge der Seile bzw. Ketten ein definiertes, jeder Zeit reproduzierbares Teleskopieren der Schiebeholme bis zu den jeweiligen Lasteinleitungsstellen aller Ausfahrzustände möglich.
- First, the first sliding beam is pushed out by means of a hydraulic cylinder between Schiebeholmkasten and Schiebeholm. The extension of the second sliding beam is synchronous, as it is mechanically connected to the first sliding beam via a pulley system made of ropes or chains. Basically, by the mechanical connection of both sliding beams and the fixed length of the ropes or chains a defined, reproducible at any time telescoping the sliding beams up to the respective load introduction points of all Ausfahrzustände possible.
Bei einem Ausschubsystem mit zwei Hydraulikzylindern oder einem Zweistufenzylinder erfolgt der Teleskopiervorgang der Schiebeholme wie folgt:
- Hierzu kann auf die Figur 1 verwiesen werden, die den prinzipiellen Aufbau eines entsprechenden teleskopierbaren Schiebeholms nach dem Stand der Technik zeigt. Ein
Schiebeholmkasten 10 nimmt einen ersten Schiebeholm 12 und einen zweiten Schiebeholm 14 auf. Schiebeholmkasten, erster Schiebeholm und zweiter Schiebeholm sind jeweils über zwei gleichzeitig mit hydraulischem Druckbeaufschlagte Hydraulikzylinder 16 und 18 oder einen hier in der Figur 1 bzw. 2 nicht dargestellten Zweistufen-Hydraulikzylinder miteinander verbunden. Bei Beaufschlagen der Zylinder mit hydraulischem Druck setzt sich zunächst der Schiebeholm mit dem geringsten mechanischen Widerstand in Bewegung. Während des Teleskopiervorgangs erhöht sich der Widerstand in der Lagerung des sich bewegenden Schiebeholms. Übersteigt der mechanische Widerstand des sich bewegenden Schiebeholms den des noch stehenden Schiebeholms, stoppt dieser und der bis dahin stehende Schiebeholm setzt sich in Bewegung. Dieser Bewegungswechsel wird zwischen den beiden Schiebeholmen während eines Teleskopiervorganges mehrfach willkürlich ausgeführt. Durch die sich ändernden mechanischen Widerstände in der Lagerung der Schiebeholme und dem dementsprechenden lastabhängigen Teleskopieren der Schiebeholme kann bei reduzierten Ausfahrzuständen kein definiertes Teleskopieren der Schiebeholme bis zu den jeweiligen Lasteinleitungsstellen erfolgen.
- Reference may be made to FIG. 1, which shows the basic construction of a corresponding telescoping sliding beam according to the prior art. A sliding
beam box 10 receives a first slidingbeam 12 and a second slidingbeam 14. Schiebeholmkasten, first sliding beam and second Schiebeholm are each connected via two simultaneously acted upon by hydraulic pressure 16 and 18 or a not shown here in the figure 1 and 2 two-stage hydraulic cylinder with each other. When the cylinder is pressurized with hydraulic pressure, the sliding beam first moves along the least mechanical resistance in motion. During the telescoping process, the resistance increases in the storage of the moving sliding beam. If the mechanical resistance of the moving sliding beam exceeds that of the still standing sliding beam, it stops and the sliding beam, which has been up to then, begins to move. This change of motion is repeatedly performed arbitrarily between the two sliding beams during a Teleskopiervorganges. Due to the changing mechanical resistance in the storage of the sliding beams and the corresponding load-dependent telescoping of the sliding beams can be done at reduced Ausfahrzuständen no defined telescoping the sliding beams up to the respective load introduction points.hydraulic cylinders
Aufgabe der Erfindung ist es daher, einen gattungsgemäßen teleskopierbaren Schiebeholm derart weiterzubilden, dass er reproduzierbar austeleskopierbar bzw. wieder einfahrbar ist, wobei insbesondere vorher festgelegte Lasteinleitungsstellen bei reduzierten Ausfahrzuständen gezielt anfahrbar sind.The object of the invention is therefore to develop a generic telescoping sliding beam such that it is reproducible austeleskopierbar or retractable, in particular, previously predetermined load introduction points are selectively approachable at reduced Ausfahrzuständen.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale des Anspruchs 1 gelöst. Demnach ist ein teleskopierbarer Schiebeholm mit einem Schiebeholmkasten und mindestens einem ersten und einem zweiten Schiebeholm vorgesehen, die ineinander teleskopierbar sind, wobei der erste Schiebeholm im Schiebeholmkasten austeleskopierbar gelagert ist. Erfindungsgemäß ist zunächst der erste Schiebeholm bis zu einem gewünschten Punkt und dann der zweite Schiebeholm austeleskopierbar, während beim umgekehrten Einfahren zunächst der zweite Schiebeholm bis zu einem gewünschten Punkt einfahrbar ist und anschließend erst der erste Schiebeholm einfahrbar ist. Die erfindungsgemäße Lösung ist dabei nicht auf zwei Schiebeholme beschränkt. Nach diesem Lösungsprinzip könnten auch mehr als zwei Schiebeholme den teleskopierbaren Schiebeholm bilden.According to the invention, this object is solved by the features of claim 1. Accordingly, a telescoping sliding beam is provided with a Schiebeholmkasten and at least a first and a second Schiebeholm, which are telescopically telescopically, wherein the first Schiebeholm is mounted austeleskopierbar Schiebeholmkasten. According to the invention, the first sliding beam is first extensible to a desired point and then the second Schiebeholm, while the reverse retraction, the second Schiebeholm is first retractable to a desired point and then only the first Schiebeholm is retractable. The solution according to the invention is not limited to two sliding beams. According to this solution principle, more than two sliding beams could form the telescoping Schiebeholm.
Bevorzugte Ausgestaltungen der Erfindung ergeben sich aus den sich an den Hauptanspruch anschließenden Unteransprüchen.Preferred embodiments of the invention will become apparent from the subsequent claims to the main claim.
Demnach sind zum Austeleskopieren bzw. Einziehen der Schiebeholme Hydraulikzylinder vorgesehen.Accordingly, hydraulic cylinders are provided for Austeleskopieren or retraction of the sliding beams.
Besonders vorteilhaft ist eine Druckfolgesteuerung für die Hydraulikzylinder vorgesehen. Mittels dieser wird zunächst der erste Schiebeholm im ersten Hydraulikzylinder kontrolliert ausgefahren, wobei danach der zweite Schiebeholm über einen zweiten Hydraulikzylinder ausgefahren wird. Beim Einfahren wiederum wird zunächst der zweite Schiebeholm über den zweiten Hydraulikzylinder kontrolliert eingefahren, wonach der erste Schiebeholm über den ersten Hydraulikzylinder eingefahren wird.Particularly advantageous is a print sequence control for the hydraulic cylinder is provided. By means of this, first the first sliding beam in the first hydraulic cylinder is extended in a controlled manner, after which the second sliding beam is extended via a second hydraulic cylinder. When retracting, in turn, the second sliding beam is first retracted in a controlled manner via the second hydraulic cylinder, after which the first sliding beam is retracted via the first hydraulic cylinder.
Die Druckfolgesteuerung kann vorteilhaft durch entsprechend in den Hydraulikleitungen, die zur Versorgung der Hydraulikzylinder dienen, versehene Ventile realisiert werden.The pressure sequence control can advantageously be realized by correspondingly provided in the hydraulic lines, which serve to supply the hydraulic cylinders, valves.
Besonders vorteilhaft lassen sich die teleskopierbaren Schiebeholme in Arbeitsmaschinen, vorzugsweise Fahrzeugkranen und Baggern, einsetzen. Daher betrifft die vorliegende Erfindung auch entsprechende Arbeitsmaschinen, vorzugsweise Fahrzeugkrane und Bagger, mit mindestens einem, vorteilhaft aber vier entsprechenden teleskopierbaren Schiebeholmen.The telescoping sliding beams can be used particularly advantageously in working machines, preferably mobile cranes and excavators. Therefore, the present invention also relates to corresponding machines, preferably mobile cranes and excavators, with at least one, but advantageously four corresponding telescopic sliding beams.

Die Figuren 1 und 2 zeigen einen teleskopierbaren Schiebeholm 5 im prinzipiellen Aufbau, wie er schon aus dem Stand der Technik bekannt war. Der teleskopierbare Schiebeholm 5 besteht im wesentlichen aus einem fest mit dem Fahrgestell eines hier nicht näher dargestellten Fahrzeugkrans verbundenen Schiebeholmkasten 10, in welchem ein erster Schiebeholm 12 in Längsrichtung verschiebbar aufgenommen ist, wobei er über den ersten Hydraulikzylinder 16 mit dem Schiebeholmkasten verbunden ist. Ein zweiter Schiebeholm 14 ist, in Längsrichtung verschiebbar, im Schiebeholm 12 gelagert und über einen zweiten Hydraulikzylinder 18 mit dem Schiebeholm 12 verbunden.Figures 1 and 2 show a
Gemäß der vorliegenden Erfindung sind nun die Ölanschlüsse der Hydraulikzylinder über eine Druck-Folgesteuerung, die entweder in die Hydraulikzylinder (in den Figuren1 und 2 nicht dargestellt) integriert oder extern in einem separaten Steuerblock (auch in den Figuren 1 und 2 nicht dargestellt) ausgeführt ist, miteinander verbunden. Dabei ist die Reihenfolge, in der die Hydraulikzylinder aus- bzw. einfahrbar sind, durch entsprechende konstruktive Maßnahmen und aufgrund der Belegung der entsprechenden Ölanschlüsse frei wählbar.According to the present invention, the oil ports of the hydraulic cylinders are now integrated via a pressure sequencer integrated into either the hydraulic cylinders (not shown in Figures 1 and 2) or externally in a separate control block (also not shown in Figures 1 and 2) , connected with each other. The order in which the hydraulic cylinders are extended or retracted, by appropriate design measures and due to the occupancy of the corresponding oil connections freely selectable.
Eine Druckfolgesteuerung, die eine Austeleskopier- bzw. Einfahrbewegung gemäß der vorliegenden Erfindung ermöglicht, ist beispielhaft in der Figur 3 gezeigt. Dort sind die Zylinder 16 und 18 schematisch dargestellt. Über eine erste Ölleitung 20, über die der Hydraulikdruck zum Ausfahren des teleskopierbaren Schiebeholms zur Verfügung gestellt wird, wird der Hydraulikzylinder 16 zunächst bis zu einem gewünschten Ausfahrzustand ausgefahren. In dieser Zeit ist ein Hydraulikventil 22, welches zwischen dem ersten Hydraulikzylinder 16 und dem zweiten Hydraulikzylinder 18 angeordnet ist, geschlossen. Hierdurch wird ein kontrolliertes Ausfahren des ersten Hydraulikzylinders 16 und damit des Schiebeholms 12 bewirkt. Zusammen mit dem Schiebeholm 12 wird selbstverständlich der in diesem angeordnete Schiebeholm 14 aus dem Schiebeholmkasten 10 geschoben. Die Relativbewegung zwischen dem Schiebeholm 12 und dem Schiebeholm 14 beträgt in diesem Ausfahrzustand null, da die Verbindung zum Hydraulikzylinder 18 durch das Ventil 22 gesperrt ist. Diese Ausfahrbewegung ist in Figur 4 dargestellt, in welcher die eingezogene Position des teleskopierbaren Schiebeholms sowie die ausgefahrene Position des Schiebeholms 12 dargestellt ist.A print sequencer that enables an expel movement in accordance with the present invention is shown by way of example in FIG. There, the
Sobald der Hydraulikzylinder 16 seine Endlage erreicht hat, steigt der hydraulische Systemdruck an. Wird ein am Ventil 22 voreingestellter Grenzdruck erreicht, öffnet dieses Ventil. Der Hydraulikzylinder 18 wird anschließend mit Hydrauliköl versorgt und fährt aus. Hierdurch wird der Schiebeholm 14 aus dem Schiebeholm 12 geschoben. Hier beträgt nun die Relativbewegung zwischen Schiebeholm 12 und Schiebeholmkasten 10 null, da der Hydraulikzylinder 16 bereits voll ausgefahren ist. Diese Situation ist in der Figur 5 gezeigt, wobei in der oberen Darstellung die Ausgangsposition vor dem Austeleskopieren des zweiten Schiebeholms 14 und im unteren Bild dann die Situation bei vollständig ausgeschobenen Schiebeholmen 14 dargestellt ist.As soon as the
Beim Einfahren wird nun zunächst der Hydraulikzylinder 18 über die Hydraulikleitung 24 beaufschlagt, wobei hier die Verbindung zum Zylinder 16 durch ein Ventil 26 (vgl. Figur 3) gesperrt wird.When retracting, first the
Der Zylinder 18 fährt ein und der Schiebeholm 14 wird in den Schiebeholm 12 gezogen, wie sich aus dem Vergleich der oberen und unteren Darstellung der Figur 6 leicht nachvollziehen lässt. Die Relativbewegung zwischen dem Schiebeholm 12 und dem Schiebeholmkasten 10 beträgt null, da die Verbindung zu dem Hydraulikzylinder 16 immer noch durch das Ventil 26 gesperrt ist.The
Anschließend erfolgt ein kontrolliertes Einfahren des Hydraulikzylinders 16, wobei die Schiebeholme 12 und 14 in den Schiebeholmkasten 10 eingefahren werden. Dies wird dadurch erreicht, dass nach Erreichen der Endlage des Hydraulikzylinders 18 der hydraulische Systemdruck ansteigt. Wird nun ein am Ventil 26 voreingestellter Druck erreicht, öffnet dieses Ventil. Darauf hin wird der Zylinder 16 mit Öl versorgt und fährt ein. Durch diese Einfahrbewegung des Hydraulikzylinders wird der Schiebeholm 12 gemeinsam mit dem Schiebeholm 14 in den Schiebeholmkasten 10 gezogen. Die Relativbewegung zwischen dem Schiebeholm 12 und dem Schiebeholm 14 beträgt null, da der Zylinder 18 bereits voll eingefahren ist.Subsequently, a controlled retraction of the
