Abstract
Description
Die Erfindung bezieht sich auf ein Hochhubflurförderzeug nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a high-lift truck according to the preamble of patent claim 1.
Hochhubflurförderzeuge benötigen naturgemäß eine Hochhubeinrichtung. Diese wird üblicherweise von höhenverstellbaren Hubgerüsten gebildet. Aufgabe der Hubgerüste ist, zu transportierende Lasten in unterschiedlichen Höhenpositionen aufzunehmen oder abzulegen und die Hublast vertikal zu bewegen.High-lift trucks naturally require a high-lift device. This is usually formed by height-adjustable masts. The task of the masts is to take loads to be transported in different height positions or store and move the lifting load vertically.
Bekannte Hubgerüste bestehen im Prinzip aus einem äußeren Standrahmen, in dem sich unmittelbar ein Lastaufnahmemittel bewegt, wie beim nicht teleskopierenden Einfachmast. Eine derartige Konstruktion wird nur noch wenig angewendet. In den meisten bekannten Fällen bewegen sich im Standmast ein oder mehrere Masten. So sind Dreifach- oder auch Vierfach-Teleskopgerüste bekannt geworden.Known masts consist in principle of an outer frame in which a load handling device moves directly, as in non-telescoping single mast. Such a construction is used only little. In most known cases, one or more masts move in the mast. Thus, triple or quadruple telescopic scaffolds have become known.
Die einzelnen Mastrahmen bestehen zumeist aus zwei seitlichen Tragprofilen, die am oberen und unteren Ende durch Querstreben verbunden sind. Die Übertragung des aus der Hublast sich ergebenden Biegemoments erfolgt zwischen den ineinander verschachtelten Mastrahmen üblicherweise über Laufrollen, die am oberen und unteren Ende der Mastrahmenprofile angeordnet sind. Der Antrieb für eine Höhenverstellung erfolgt normalerweise mittels hydraulischer Hubzylinder, die eine Relativbewegung zwischen den einzelnen Hubmastrahmen erzeugen.The individual mast frames usually consist of two lateral support profiles, which are connected at the top and bottom by transverse struts. The transmission of the bending load resulting from the lifting load is carried out between the nested mast frames usually via rollers, which are arranged at the top and bottom of the mast frame profiles. The drive for a height adjustment is usually by means of hydraulic lifting cylinder, which generate a relative movement between the individual mast frame.
Damit sich durch das Biegemoment einer sich in mehr oder weniger großer Höhe befindlichen Last das Hubgerüst möglichst wenig verformt, ist die Konstruktion so beschaffen, dass das Hubgerüst in seiner Hauptbelastungsrichtung biegesteif ist. Eine zu große Verformung führt zur Längsverschiebung des Lastschwerpunkts und damit zur Vergrößerung des auf das Flurförderzeug wirkenden Kippmoments. Hierdurch wird die Standsicherheit des Fahrzeugs negativ beeinflusst. Die notwendige Biegesteifigkeit wird durch die Auswahl von Hubrahmenprofilen mit großen Flächenträgheitsmomenten und durch aufwendige Hinterzugkonstruktionen erreicht, was einen erheblichen Materialeinsatz und damit ein hohes Gewicht und einen großen Aufwand bedingt.So that the mast deforms as little as possible by the bending moment of a load located in more or less high height, the construction is such that the mast is rigid in its main loading direction. Excessive deformation leads to the longitudinal displacement of the center of gravity of the load and thus to an increase in the tilting torque acting on the industrial truck. As a result, the stability of the vehicle is negatively affected. The necessary bending stiffness is achieved by the selection of lifting frame profiles with large area moments of inertia and by complex rear link constructions, which requires a considerable amount of material and thus a high weight and a great deal of effort.
Neben der Hauptbiegebelastung kann außerdem eine seitliche Biegung auftreten, die durch exzentrische (unsymmetrische) Schwerpunktlage der Hublast oder durch dynamische seitliche Massenkräfte hervorgerufen wird. Speziell bei sogenannten Schmalgang-Gabelstaplern, die für die Aufnahme seitlich zur Fahrzeugachse versetzten Lasten eingerichtet sind, kann die seitliche Biegebelastung dominant werden. Durch die resultierende seitliche Verbiegung des Hubmastes wird der seitliche Hublasthebelarm vergrößert und damit auch das seitliche Kippmoment erhöht. Die Steifigkeit der Hubmastrahmen gegen seitliche Verbiegung wird üblicherweise dadurch erreicht, dass die beiden seitlichen Tragprofile des Hubmastrahmens durch massive Querversteifungen (leiterförmig) verbunden werden. Die aufwendigen Querversteifungen verhindern die Sicht durch den Hubmastrahmen und vergrößern dessen Gewicht.In addition to the main bending load may also occur a lateral bending, which is caused by eccentric (asymmetrical) center of gravity of the lifting load or by dynamic lateral mass forces. Especially in so-called narrow-aisle forklifts, which are set up for receiving laterally offset to the vehicle axle loads, the lateral bending load can become dominant. Due to the resulting lateral bending of the mast, the lateral Hublasthebelarm is increased and thus also the increased lateral tilting moment. The rigidity of the mast frame against lateral bending is usually achieved in that the two lateral support profiles of the mast frame are connected by massive transverse reinforcements (ladder-shaped). The elaborate transverse stiffeners prevent visibility through the mast frame and increase its weight.

Der Erfindung liegt die Aufgabe zugrunde, ein Hochhubflurförderzeug zu schaffen, dessen Hubvorrichtung eine minimale Biegeverformung in Längs-und Querrichtung erleidet und sich gleichwohl durch einen geringen Materialaufwand und durch gute Durchsichteigenschaften auszeichnet.The invention has for its object to provide a high-lift truck, the lifting device suffers a minimal bending deformation in the longitudinal and transverse directions and yet characterized by a low cost of materials and good transparency properties.
Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst.This object is solved by the features of patent claim 1.
Bei dem erfindungsgemäßen Hochhubflurförderzeug sind mindestens drei unabhängig wirkende lineare Hubantriebe vorgesehen, von denen jeder einen unteren, in linearer Richtung feststehenden und einen oberen, zumindest in linearer Richtung beweglichen Teil aufweist. Die unteren Teile sind mit dem Rahmen so verbunden, dass ihre Abstützpunkte in Längs- und Querrichtung des Flurförderzeuges einen Abstand voneinander haben, während ihre höhenverstellbaren oberen Teile mit einer steifen, vorzugsweise horizontalen Hubplattform verbunden sind. Die Lastaufnahmevorrichtung ist an der Hubplattform angehängt.In the high-lift truck according to the invention at least three independently acting linear lifting drives are provided, each of which has a lower, fixed in the linear direction and an upper, at least in the linear direction movable part. The lower parts are connected to the frame so that their support points in the longitudinal and transverse directions the truck have a distance from each other, while their height-adjustable upper parts are connected to a rigid, preferably horizontal lifting platform. The load handling device is attached to the lifting platform.
Vorzugsweise sind nach einer Ausgestaltung der Erfindung die Hubantriebe symmetrisch zur Fahrzeuglängsachse angeordnet. Vorzugsweise sind zwei Hubantriebe im vorderen Bereich und ein Hubantrieb im hinteren Bereich des Rahmens angeordnet.Preferably, according to one embodiment of the invention, the lifting drives are arranged symmetrically to the vehicle longitudinal axis. Preferably, two lifting drives are arranged in the front region and a lifting drive in the rear region of the frame.
Das Lastaufnahmemittel ist nach einer weiteren Ausgestaltung der Erfindung mittels mindestens eines linearen Hubantriebs an der Hubplattform aufgehängt. Diese Hubeinrichtung kann auch als Initialhubeinrichtung verstanden werden.The load-receiving means is suspended according to a further embodiment of the invention by means of at least one linear lifting drive on the lifting platform. This lifting device can also be understood as Initialhubeinrichtung.
Der Grundgedanke der Erfindung ist, den Lastmomenten nahe ihres Einleitungsbereichs am lastnahen Ende der ausgefahrenen Hubeinrichtung durch Kräftepaare zu begegnen. Dadurch kann im Hubwerk auf langgestreckte biegesteife Strukturen ganz oder teilweise verzichtet werden.The basic idea of the invention is to counteract the load moments near their introduction region at the load-near end of the extended lifting device by force pairs. As a result, in the hoist on elongate rigid structures completely or partially be dispensed with.
Nach einer weiteren Ausgestaltung der Erfindung können die unbeweglichen unteren Teile der Hubantriebe eine Führung für die Lastaufnahmevorrichtung aufweisen.According to a further embodiment of the invention, the immovable lower parts of the lifting drives can have a guide for the load-receiving device.
Nach einer weiteren Ausgestaltung der Erfindung sind die Hubantriebe für die Aufnahme unterschiedlicher Axialkräfte ausgelegt. Außerdem ist nach einer weiteren Ausgestaltung der Erfindung vorgesehen, dass die Hubantriebe sowohl Zug- als auch Druckkräfte erzeugen. Damit können auch Momente von Lasten aufgenommen werden, deren Angriffspunkt außerhalb der von den Hubantrieben aufgespannten Fläche liegen.According to a further embodiment of the invention, the lifting drives are designed for receiving different axial forces. It is also provided according to a further embodiment of the invention that the lifting drives generate both tensile and compressive forces. In this way, it is also possible to absorb moments of loads whose point of application lies outside the area spanned by the lifting drives.
Nach einer weiteren Ausgestaltung der Erfindung wird die Stabilität des Hubsystems durch synchrone Ausfahrwege der einzelnen Hubantriebe erreicht. Hierzu kann eine Steuer- oder Regeleinrichtung vorgesehen werden, wobei diese dafür sorgt, dass die Ausfahrwege der einzelnen Hubantriebe gleich sind. Als Regelgröße kann statt der Ausfahrwege auch die räumliche Winkellage der Plattformstruktur am oberen Ende der Hubantriebe dienen. In diesem Fall kann auch eine gewollte Neigung des Hubsystems eingestellt werden. Für die Einstellung einer Neigung ist jedoch obligatorisch, daß die Anbindung der beweglichen Teile die Hubantriebe an der Hubplattform nicht starr ist, sondern mehr oder weniger gelenkig.According to a further embodiment of the invention, the stability of the lifting system is achieved by synchronous extension paths of the individual lifting drives. For this purpose, a control or regulating device can be provided, which ensures that the extension paths of the individual linear actuators are the same. As a controlled variable, the spatial angular position of the platform structure at the upper end of the linear actuators can serve instead of the extension paths. In this case, a desired inclination of the lifting system can be adjusted. However, for the adjustment of an inclination is mandatory that the connection of the moving parts, the lifting drives on the lifting platform is not rigid, but more or less articulated.
Für die Hubantriebe können übliche lineare Hubvorrichtungen verwendet werden, vorzugsweise Hydraulikzylinder. Zur Vergrößerung der erzielbaren Hubhöhe werden vorzugsweise Teleskopanordnungen eingesetzt. Die Hydraulikzylinder können wie bei einem Hexapoden an dem Rahmen und der Plattform angelenkt sein. Sie sind dann zur Vertikalen geneigt.For the linear actuators conventional linear lifting devices can be used, preferably hydraulic cylinders. To increase the achievable lifting height telescopic arrangements are preferably used. The hydraulic cylinders may be hinged to the frame and platform as in a hexapod. They are then inclined to the vertical.
Nach einer anderen Ausgestaltung der Erfindung ist am oberen Ende des unbeweglichen Teils der Hubantriebe eine weitere horizontale Verbindungsstruktur vorgesehen, um eine geeignete Versteifung zu bewirken. Diese kann auch als Schutzdach für eine Fahrerkabine des Flurförderzeugs dienen.According to another embodiment of the invention, a further horizontal connecting structure is provided at the upper end of the stationary part of the lifting drives to effect a suitable stiffening. This can also serve as a protective roof for a cab of the truck.
Bei sogenannten Hochregal-Vertikalkomissionierfahrzeugen kann deren gesamte Hubbühne mit Fahrerplatz, Zusatzhub und Schwenkschubeinheit an der Hubplattform angehängt werden. Damit ergibt sich eine besonders einfache Konstruktionsform für diesen Fahrzeugtyp.In so-called high-shelf vertical picking vehicles whose entire lifting platform with driver's seat, additional stroke and swivel unit can be attached to the lifting platform. This results in a particularly simple design form for this vehicle type.
