Description

„Portalhubwagen zum Einsatz in Containerterminals und für allgemeine Transportaufgaben" "Straddle carrier for use in container terminals and general transport tasks"
Die Erfindung bezieht sich auf einen Portalhubwagen (Straddle Carrier) zum Einsatz in Containerterminals und für allgemeine Transportaufgaben, mit einem Rahmengestell, einem Lastaufnahmemittel, das zwischen dem Rahmengestell hängt und mit einer Last, vorzugsweise einem Container, verriegelbar ist, Hubwinden, mittels denen das Lastaufnahmemittel vertikal bewegbar ist, und Fahrträgern, die am unteren Bereich des Rahmenge- stells angeordnet sind und jeweils eine Vielzahl in einer Reihe angeordneter Räder aufweisen. The invention relates to a straddle carrier (Straddle Carrier) for use in container terminals and for general transport tasks, with a frame, a load receiving means which is suspended between the frame and with a load, preferably a container, lockable, hoisting winches, by means of which the load-carrying means is vertically movable, and driving beams, which are arranged at the lower portion of the Rahmenge- stells and each having a plurality of arranged in a row wheels.
Bei bekannten derartigen Portalhubwagen sind die Fahrwerke mittels Federungen abgestützt. Bei dieser Art der Abstützung kann es zu erheblichen Unterschieden bei der Lastverteilung auf die einzelnen an einem Fahrträger angeordneten Räder kommen, wobei auch Überlastungen einzelner Räder nicht ausgeschlossen werden können. Ausgehend von dem vorstehend geschilderten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, einen Portalhubwa¬ gen zum Einsatz in Containerterminals und für allgemeine Transportaufgaben derart weiterzuentwickeln, dass zum einen eine gleichmäßigere Lastverteilung auf die an einem Fahrträger angeordneten Räder ermöglicht wird und zum anderen der konstruktiv-technische Aufwand, der zum Ausgleich von Gelän- deunebenheiten etc. an den Fahrträgern realisiert werden muß, erheblich reduziert ist. In known such pallet trucks, the trolleys are supported by suspensions. In this type of support, it can lead to significant differences in the load distribution to the individual arranged on a driving carrier wheels, and overloads of individual wheels can not be excluded. Starting from the above described prior art, the invention has the object of providing a Portalhubwa ¬ gene for use in container terminals and for general Further develop transport tasks such that on the one hand a more even load distribution on the wheels arranged on a driving carrier is made possible and on the other hand, the constructional-technical effort, which must be realized to compensate for bumps ebb-etc. on the driving beams, is considerably reduced.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass jeweils zwei an einem Fahrträger des Portalhubwagens neben- bzw. hintereinander angeordnete Radträger, an denen jeweils ein Rad des Portalhubwagens gelagert ist, an einer Wippe gehaltert sind, die in Bezug auf den Fahrträger um einen horizontal angeordneten Gelenkzapfen verschwenkbar ist. Durch die zwischen jeweils einem Radpaar einerseits und dem Fahrträger des erfindungsgemäßen Portalhubwagens andererseits angeordnete Wippenkonstruktion wird erreicht, dass bei ungebremster Fahrt des Portalhubwagens Geländeunregelmäßigkeiten völlig ausgeglichen werden können, so dass eine völlige Vergleichmäßigung der Lastverteilung auf alle an einem Fahrträger ange- ordneten vier Räder erreicht werden kann; Überlastungen des einen oder anderen Rades können zuverlässig vermieden werden. Darüber hinaus wird durch die im Falle des erfindungsgemäßen Portalhubwagens vorgesehene Wippenkonstruktion eine im Vergleich zum Stand der Technik maschinenbaulich robustere und günstigere Bauweise erreicht, wobei aufwändige Federpakete mit Abdichtungen und Lenkwellen mit teurer Verzahnungsgeometrie für das Verschieben unter Last entfallen können. This object is achieved in that two adjacent to a driving carriage of the straddle carrier or successively arranged wheel carrier, on each of which a wheel of the straddle carrier is mounted, are mounted on a rocker, with respect to the driving beam to a horizontally arranged pivot pin is pivotable. By arranged between each pair of wheels on the one hand and the carrier of the straddle dolly according to the invention on the other hand Rocker construction ensures that unimpeded ride the straddle terrain irregularities can be completely compensated, so that a complete equalization of the load distribution on all arranged on a carriage four wheels are achieved can; Overloads of one or the other wheel can be reliably avoided. In addition, is provided by the proposed in the case of the gantry invention rocker construction in comparison to the state of the art mechanically more robust and cheaper construction, with complex spring assemblies can be omitted with seals and steering shafts with expensive Verzahnungsgeometrie for moving under load.
Zur konstruktiv-technisch wenig aufwändigen Ausgestaltung der Wippenkonstruktion ist es vorteilhaft, wenn der Gelenkzapfen jeder Wippe am freien Ende eines am Fahrträger fixierten Zwischenträgers angeordnet ist. Gemäß einer vorteilhaften Weiterbildung des erfindungsgemäßen Portalhubwagens ist jedes Rad bzw. jeder Radträger desselben an der ihm zugeordneten Wippe separat lenkbar. For structurally-technically less complicated design of the rocker construction, it is advantageous if the pivot pin of each rocker is arranged at the free end of a carrier fixed to the intermediate carrier. According to an advantageous embodiment of the invention Portalhubwagens each wheel or each wheel carrier of the same on the rocker associated with it is steered separately.
Dies läßt sich vorteilhaft erreichen, wenn jedem Rad bzw. jedem Radträger ein Traglenkgetriebe zugeordnet ist, dessen Ausgangswelle drehfest mit einem Gelenkzapfen des Rades bzw. Radträgers verbunden und in einem traglenkgetriebeseitigen Wälzlager drehbar gelagert ist. Da sich die Wippenkonstruktion stets an den Untergrund anpaßt, kann das Traglenkgetriebe ohne vertikalen Längenausgleich konstruiert werden. This can be advantageously achieved if each wheel or each wheel carrier is associated with a support steering gear, the output shaft rotatably connected to a pivot pin of the wheel or wheel carrier and is rotatably mounted in a traglenkgetriebeseitigen bearings. Since the rocker design always adapts to the ground, the support steering gear can be constructed without vertical length compensation.
Zweckmäßigerweise sind die beiden an einem Fahrträger vorge- sehenen Wippen an den Endabschnitten des Fahrträgers angeordnet, d.h., eine Wippe befindet sich an dem in Fahrtrichtung vorderen und die andere Wippe an dem in Fahrtrichtung hinteren Endabschnitt des Fahrträgers . Im Folgenden wird die Erfindung anhand einer Ausführungsform unter Bezugnahme auf die Zeichnung näher erläutert. The two rockers provided on a driving carrier are expediently arranged at the end sections of the driving carrier, that is to say one rocker is located at the front in the direction of travel and the other rocker at the rear end section of the driving carrier in the direction of travel. In the following the invention will be explained in more detail with reference to an embodiment with reference to the drawing.

Des Weiteren ist das Lastaufnahmemittel 4 mittels einer in der in Figur 1 gezeigten Ausführungsform des Portalhubwagens 1 am Lastaufnahmemittel 4 angeordneten Hubwinde 8 zwischen den vertikalen Stützen 5 des Rahmengestells 2 vertikal bewegbar. To this straddle carrier 1 includes a lifting device 4, which may be a spreader or a Toppspreader. The load-carrying means is arranged between the two drivers 3 associated vertical supports 5 of the frame 2. It is connected by suitable connecting means 6 with a container 7 or locked. Furthermore, the load-receiving means 4 is vertically movable between the vertical supports 5 of the frame 2 by means of a hoist winch 8 arranged on the load-receiving means 4 in the embodiment of the gantry lifting vehicle 1 shown in FIG.
An einem Oberrahmen 9 des Rahmengestells 2 ist eine Fahrerka- bine 10 vorgesehen, aus der heraus eine Bedienungsperson des Portalhubwagens 1 diesen und sein Lastaufnahmemittel 4 fahren bzw. steuern kann. On an upper frame 9 of the frame 2, a driver's cab 10 is provided, out of which an operator of the gantry truck 1 can drive or control this and its load-carrying means 4.
Die beiden Fahrträger 3 des Portalhubwagens 1, von denen in Figur 1, wie bereits erwähnt, nur einer sichtbar ist, tragen in der dargestellten Ausführungsform des Portalhubwagens 1 jeweils vier Räder 11, denen jeweils ein Radträger 12 zuge¬ ordnet ist. Wie am besten aus Figur 2 hervorgeht, sind bei der in den Figuren dargestellten Ausführungsform des erfindungsgemäßen Portalhubwagens 1 jeweils zwei neben- bzw. hintereinander an einem Fahrträger 3 angeordnete Räder 11 zu einem Radpaar 14 bzw. 15 zusammengefaßt. Das Radpaar 14 ist nahe dem bzw. am in Figur 2 linken Endabschnitt, das Radpaar 15 nahe dem bzw. am in Figur 2 rechten Endabschnitt des Fahrträgers 3 angeord- net . The two carriage 3 of the portal lift truck 1, of which in Figure 1, as already mentioned, only one is visible in the illustrated embodiment of the portal lift truck 1 four wheels 11, each of which a wheel 12 is assigned ¬ assigns. As best shown in FIG. 2, in the embodiment of the straddle carrier 1 according to the invention shown in the figures, two adjacent or one behind the other are respectively attached a Fahrträger 3 arranged wheels 11 combined to form a pair of wheels 14 and 15 respectively. The pair of wheels 14 is located near or at the left-hand end section in FIG. 2, the pair of wheels 15 being arranged near or on the right-hand end section of the driving support 3 in FIG.
Die beiden Räder 11 jedes Radpaares 14 bzw. 15 sind mittels ihrer Radträger 12 unabhängig voneinander lenkbar an einer Wippe 13 gelagert. Die Wippe 13 ihrerseits ist um einen hori- zontal angeordneten Gelenkzapfen 16 schwenkbar, der am freien Ende eines Zwischenträgers 17 angeordnet ist, der mit seinem anderen Ende am entsprechenden Endabschnitt des Fahrträgers 3 fixiert ist. Der fest mit dem Fahrträger 3 verbundene Zwischenträger 17 trägt somit dreh- bzw. schwenkbar die Wippe 13, an der die beiden Räder 11 separat lenkbar angeordnet sind. The two wheels 11 of each pair of wheels 14 and 15 are supported by means of their wheel carrier 12 independently steerable on a rocker 13. Die beiden Räder 11, 14 und 15 sind in einer Ausnehmung 14 gelagert. The rocker 13 in turn is pivotable about a horizontally arranged pivot pin 16 which is arranged at the free end of an intermediate carrier 17, which is fixed at its other end to the corresponding end portion of the driver carrier 3. The fixedly connected to the carrier 3 intermediate carrier 17 thus rotatably or pivotally carries the rocker 13, on which the two wheels 11 are arranged separately steerable.
Jedem Rad 11 ist ein an der Wippe 13 angeordneter Lenkmotor 16 zugeordnet, mittels dem über ein Lenkgetriebe 19 eine Ausgangswelle desselben bzw. ein damit drehfest verbundener Lenkzapfen des jeweiligen Rades 11 drehbar ist. Each wheel 11 is associated with an arranged on the rocker 13 steering motor 16, by means of which via a steering gear 19, an output shaft thereof or a rotatably connected steering pin of the respective wheel 11 is rotatable.
Das Lenkgetriebe 19 ist hierbei als Traglenkgetriebe ausges- taltet, wobei die in den Figuren nicht gezeigte Ausgangswelle des Lenkgetriebes 19 und damit - mittelbar - der mit dieser Ausgangswelle drehfest verbundene Lenkzapfen in einem lenkge- triebeseitigen Wälzlager drehbar gelagert ist. Aufgrund der Wippenkonstruktion 13, 16, 17, die zwischen den beiden Radträgern 12 jeweils eines Radpaares 14, 15 einerseits und dem Fahrträger 3 des Portalhubwagens 1 andererseits vorgesehen ist, wird bei ungebremster Fahrt des Portalhubwa gens 1 die Last auf alle vier an einem Fahrträger 3 des Por talhubwagens 1 angeordneten Räder 11 gleichmäßig verteilt, d.h., keines der Räder 11 wird überlastet. The steering gear 19 is hereby designed as a support steering gear, wherein the output shaft of the steering gear 19 not shown in the figures, and thus - indirectly - the steering pin rotatably connected to this output shaft is rotatably mounted in a steering gear-side roller bearing. Due to the rocker construction 13, 16, 17, between the two wheel carriers 12 each have a pair of wheels 14, 15 on the one hand and the carrier 3 of the gantry truck 1 on the other is provided, the load on all four on a carriage 3 of the Por talhubwagens 1 arranged wheels 11 is evenly distributed during unrestricted travel of the Portalhubwa 1, ie, none of the wheels 11 is overloaded.
