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 zum Einsatz in Containerterminals und für allgemeine Transportaufgaben, mit einem Rahmengestell, einem Spreader, der zwischen dem Rahmengestell hängt und mit einem Container verriegelbar ist, Fahrträgern, die am unteren Bereich des Rahmengestells angeordnet sind und jeweils eine Vielzahl in einer Reihe angeordneter Räder aufweisen, und Hubwinden, mittels denen Hubseile auf- und abrollbar sind, die einerseits an den Hubwin- den angebracht und andererseits mittels Hubseilaufhängepunk- ten mit dem Spreader verbunden sind. The invention relates to a straddle carrier for use in container terminals and for general transport tasks, with a frame, a spreader, which hangs between the frame and can be locked with a container, drivers, which are arranged at the bottom of the frame and in each case a variety in Have a number of arranged wheels, and hoisting winches, by means of which hoisting ropes are up and unrolled, on the one hand attached to the Hubwin- the and on the other hand by Hubseilaufhängepunk- th associated with the spreader.
Bei bekannten derartigen Portalhubwagen sind die spreadersei- tigen Enden der Hubseile in geeigneter Weise an Jochträgern oder Jochbalken angebracht, von denen jeweils einer über den beiden Endabschnitten des Spreaders angeordnet ist. Der In known such straddle carriers, the spreadersei- term ends of the hoisting ropes are suitably mounted on yoke beams or yoke beams, one of which is arranged above the two end portions of the spreader. Of the
Spreader ist dann an den beiden Jochbalken bzw. Jochträgern aufgehängt . Ausgehend von dem vorstehend geschilderten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, den konstruktiv¬ technischen Aufbau eines Portalhubwagens zu vereinfachen und Spreader is then hung on the two yoke beams or Jochträgern. Based on the above-described prior art, the present invention seeks to simplify the constructive ¬ technical design of a straddle carrier and
BESTÄTIGUNGSKOPIE die Möglichkeiten zur Positionierung des Spreaders mit oder ohne an ihm verriegelten Container zu verbessern. CONFIRMATION COPY to improve the possibilities for positioning the spreader with or without containers locked to it.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die spreaderseitigen Hubseilaufhängepunkte unmittelbar am Sprea- der ausgebildet sind. Erfindungsgemäß wird eine direkte Aufhängung des Spreaders an den ihm zugeordneten Enden der Hubseile bewerkstelligt. Positionsveränderungen des Portalhubwagens bzw. der fest beispielsweise am Oberrahmen des Portal- hubwagens installierten Hubwinden werden somit ohne Zwischenschaltung weiterer Bauteile unmittelbar und direkt auf den Spreader übertragen. Irgendwelche zwischengeschalteten Bauteile, wie Jochträger bzw. Jochbalken etc., können entfallen. Zweckmäßigerweise können den spreaderseitigen Hubseilaufhän- gepunkten zugeordnete Seilenden der Hubseile unmittelbar bzw. direkt am Spreader angebracht sein. This object is achieved in that the spreaderseitigen Hubseilaufhängepunkte are formed directly on spreader. According to the invention, a direct suspension of the spreader is accomplished at its associated ends of the hoisting ropes. Position changes of the gantry lift truck or the fixed hoist winches installed, for example, on the upper frame of the gantry lift truck are thus transmitted directly and directly to the spreader without the interposition of further components. Any intermediary components, such as Jochträger or yoke beams, etc., can be omitted. Expediently, cable ends of the hoisting cables assigned to the spreader-side hoisting rope suspension points can be attached directly or directly to the spreader.
Gemäß einer vorteilhaften Ausführungsform des erfindungsgemä- ßen Portalhubwagens sind die spreaderseitigen Hubseilaufhän¬ gepunkte als Umlenkrollen ausgebildet. Durch Auf- bzw. Abrollen der Hubseile mittels der Hubwinden, an denen die Hubseile beidendig angebracht sind, kann die vertikale Beweglichkeit des Spreaders und ggf. des damit verriegelten Containers in schonender Weise bewerkstelligt werden, so dass Container mit einem vergleichsweise geringen Aufwand transportabel und po¬ sitionier- bzw. stapelbar sind. According to an advantageous embodiment of the inventive gantry hoist the spreaderseitigen Hubseilaufhän ¬ ge points are designed as deflection rollers. By winding or unwinding of the hoisting ropes on which the hoisting ropes are attached at both ends, the vertical mobility of the spreader and possibly the container locked therewith can be accomplished in a gentle manner, so that containers with a relatively low cost portable and po ¬ sitionier- or stackable.
Vorteilhaft ist an jedem der vier Eckbereiche des Spreaders ein Hubseilaufhängepunkt bzw. eine Umlenkrolle angeordnet, so dass die Bewegungen des Spreaders sowie des ggf. an dem Spreader verriegelten Containers gut kontrollier- bzw. einschränkbar sind. Advantageously, a Hubseilaufhängepunkt or a guide roller is arranged at each of the four corner regions of the spreader, so that the movements of the spreader and possibly on the Spreader locked containers are well controlled or restrictable.
Um aufwändige Fahrmanöver des Portalhubwagens in den Contai- 5 nergassen von Containerterminals zur Feinpositionierung des Spreaders bzw. des mit dem Spreader verriegelten Containers zu minimieren oder möglichst ganz zu vermeiden, ist es vorteilhaft, wenn der Portalhubwagen mit einer Positioniervorrichtung ausgerüstet ist, die zwischen dem Spreader einer¬ l ei seits und dem Rahmengestell andererseits angeordnet ist und mittels der der Spreader im Rahmengestell und in Bezug auf das Rahmengestell in seiner Horizontalebene beliebig positionierbar ist. Durch die so geschaffene Verstellmöglichkeit des Spreaders sowohl in X- als auch in Y-Richtung seiner Horizon- 15 talebene ist es möglich, den Spreader ohne den Portalhubwagen zu verfahren, exakt in derjenigen Stellung zu positionieren, in der er in einfacher Weise mit einem Container verriegelbar ist, bzw. in der ein am Spreader verriegelter Container vom Spreader gelöst werden soll. In order to minimize expensive driving maneuvers of the straddle carrier in the container nergassen of container terminals for fine positioning of the spreader or locked with the spreader container or avoid as completely as possible, it is advantageous if the straddle carrier is equipped with a positioning device between the spreader a ¬ l ei hand, and the frame is arranged and on the other hand by means of the spreader in the frame and with respect to the frame in its horizontal plane is positioned as desired. By thus created adjustment of the spreader both in the X and in the Y direction of his horizontal plane 15 tale, it is possible to move the spreader without the straddle carrier to position exactly in that position in which he easily with a container is lockable, or in which a locked on the spreader container is to be solved by the spreader.

Gemäß einer vorteilhaften Ausführungsform lässt sich dessen Positioniervorrichtung durch Versteilglieder realisieren, die mit einem Ende am Spreader und mit dem anderen Ende gleitend verschieblich an einer vertikalen Stütze des Rahmengestells According to an advantageous embodiment, the positioning device can be realized by adjusting members, which with one end on the spreader and with the other end slidingly displaceable on a vertical support of the frame

Depending on the vertical position of the spreader in relation to the frame, the adjusting members move on their associated vertical supports of the frame and can be used in each vertical position of the spreader for fine positioning of the same
30 den. Vorteilhaft ist an jedem der Eckbereiche des Spreaders jeweils ein Versteilglied angebracht, das mit der diesem Eckbereich nächsten vertikalen Stütze des Rahmengestells des Portalhubwagens gleitend verschieblich verbunden ist. 30 the. Advantageously, an adjusting member is attached to each of the corner regions of the spreader, which is slidably connected to the next vertical support of the frame frame of the portal lifting carriage this corner region.
Alternativ kann es zweckmäßig und günstig sein, nur drei Eckbereiche des Spreaders mit einem entsprechenden Verstellglied zu versehen; hierdurch können insbesondere die Sichtmöglichkeiten der Bedienungsperson des Portalhubwagens verbessert werden. Alternatively, it may be expedient and advantageous to provide only three corner regions of the spreader with a corresponding adjusting member; As a result, in particular the visibility of the operator of the straddle carrier can be improved.
Gemäß einer vorteilhaften Ausführungsform des erfindungsgemäßen Portalhubwagens können die Versteilglieder als Elektrozy- linder oder Elektrolinearantrieb ausgebildet sein. According to an advantageous embodiment of the straddle carrier according to the invention the Versteilglieder can be designed as an electro-cylinder or electric linear drive.
Besonders zweckmäßig lassen sich die VerStellglieder der Positioniervorrichtung als Fluid-, vorzugsweise als Hydrau¬ likzylinder ausbilden, die mittels eines Gelenks gelenkig mit jeweils einem Eckbereich des Spreaders und mittels eines Gleitgelenks gelenkig und gleitend verschieblich mit der diesem Eckbereich des Spreaders zugeordneten bzw. nächsten vertikalen Stütze des Rahmengestells verbunden sind. Durch entsprechende separate Beaufschlagung der Hydraulikzylinder mit Hydraulikfluid lässt sich in exakt dosierter Weise die Posi- tion des Spreaders innerhalb des Rahmengestells fein justieren . The adjustment members of the positioning device can be particularly useful as a fluid, preferably form as Hydrau ¬ likzylinder hingedly articulated and slidably with this corner region of the spreader associated or by means of an articulation with a respective corner of the spreader and by means of a slip joint next vertical support the frame are connected. By appropriate separate pressurization of the hydraulic cylinder with hydraulic fluid, the position of the spreader within the framework can be finely adjusted in a precisely metered manner.
Es ist auch möglich, die Versteilglieder bei einem entsprechenden Anforderungsprofil als pneumatische Zylinder auszuge- stalten. Eine weitere Funktionalität der Positioniervorrichtung ergibt sich, wenn an den Fluid- bzw. Hydraulikzylindern oder pneumatischen Zylindern derselben ein Grenzdruck einstellbar ist, bei dessen Erreichen bzw. Überschreiten die Fluid- bzw. Hy- draulikzylinder oder pneumatischen Zylinder abblasen. Hierdurch kann die Positioniervorrichtung zugleich der Stoßabsorption dienen, indem durch entsprechende Einstellung des Grenzdrucks sichergestellt wird, dass die Fluid- bzw. Hydraulikzylinder oder pneumatischen Zylinder abblasen, falls es zu einem Zusammenstoß beispielsweise des am Spreader verriegelten Containers mit einem Hindernis kommt. It is also possible to design the adjustment members as pneumatic cylinders for a corresponding requirement profile. A further functionality of the positioning device is obtained when a limiting pressure is adjustable on the fluid or hydraulic cylinders or pneumatic cylinders of the same, at the reaching or exceeding of which the fluid or hydraulic cylinders or pneumatic cylinders blow off. In this way, the positioning device can also serve the impact absorption, by ensuring by appropriate adjustment of the limit pressure that blow off the fluid or hydraulic cylinder or pneumatic cylinder, if it comes to a collision, for example, of the spreader locked container with an obstacle.
Zum Schutz der Fluid- bzw. Hydraulikzylinder oder pneumatischen Zylinder gegen Querkräfte, die durch derartige Bauteile schlecht oder nicht aufnehmbar sind, ist es vorteilhaft, wenn jedem Fluid- bzw. Hydraulikzylinder oder pneumatischen Zylinder der Positioniervorrichtung eine Teleskopeinrichtung zugeordnet ist, mittels der auf den Fluid- bzw. Hydraulikzylinder oder pneumatischen Zylinder einwirkende Querkräfte aufnehm- und ableitbar sind. To protect the fluid or hydraulic cylinder or pneumatic cylinder against transverse forces that are bad or not absorbable by such components, it is advantageous if each fluid or hydraulic cylinder or pneumatic cylinder of the positioning device is associated with a telescopic device by means of the fluid - or hydraulic cylinder or pneumatic cylinder acting transverse forces are absorbed and deduced.
Alternativ kann auch vorgesehen sein, jedem Fluid- bzw. Hydraulikzylinder oder pneumatischen Zylinder der Positioniervorrichtung eine Knickarmeinrichtung zuzuordnen, die eben- falls dazu dient, auf den Fluid- bzw. Hydraulikzylinder oder pneumatischen Zylinder einwirkende Querkräfte aufzunehmen und abzuleiten . Alternatively, it can also be provided to associate with each fluid or hydraulic cylinder or pneumatic cylinder of the positioning device an articulated arm device, which likewise serves to absorb and divert transverse forces acting on the fluid or hydraulic cylinder or pneumatic cylinder.
Selbstverständlich ist es auch möglich, je nach Anforderungs- profil für einen oder mehrere Fluid- bzw. Hydraulikzylinder oder pneumatische Zylinder Teleskopeinrichtungen und für den bzw. die anderen Fluid- bzw. Hydraulikzylinder oder pneumatischen Zylinder Knickarmeinrichtungen vorzusehen. Of course, it is also possible, depending on the requirement profile for one or more fluid or hydraulic cylinders or pneumatic cylinder telescopic devices and for the or the other fluid or hydraulic cylinder or pneumatic cylinder Knickarmeinrichtungen provide.
Im Folgenden wird die Erfindung anhand von Ausführungsformen unter Bezugnahme auf die Zeichnung näher erläutert. In the following the invention will be explained in more detail by means of embodiments with reference to the drawing.

Jeder Hydraulikzylinder 20, 21, 22, 23 ist an einem Ende durch ein Gelenk 24 mit dem Spreader 6 verbunden, wobei die Anordnung des Gelenks 24 nahe den Eckbereichen 15, 16, 17 bzw. 18 vorgesehen ist. Each hydraulic cylinder 20, 21, 22, 23 is connected at one end by a hinge 24 to the spreader 6, wherein the arrangement of the joint 24 is provided near the corner regions 15, 16, 17 and 18, respectively.
Mit seinem anderen Ende ist jeder Hydraulikzylinder 20, 21, 22, 23 über ein Gleitgelenk 25 mit derjenigen vertikalen Stütze 4 des Rahmengestells 2 des Portalhubwagens 1 verbun¬ den, die dem jeweiligen Eckbereich 15, 16, 17 bzw. 18 des Spreaders 6 gegenüberliegt bzw. zunächst angeordnet ist. Die Gleitgelenke 25 bewegen sich mit den Vertikalbewegungen des Spreaders 6 auf- und abwärts an den ihnen jeweils zugeordneten vertikalen Stützen 4, da sie dort in Vertikalrichtung gleitend verschieblich angebracht sind. With its other end, each hydraulic cylinder 20, 21, 22, 23 through a slip joint 25 with those vertical upright 4 of the frame 2 of the straddle carrier 1 verbun ¬ which is opposed to the respective corner portion 15, 16, 17 and 18 of the spreader 6 or is initially arranged. The sliding joints 25 move with the vertical movements of the spreader 6 up and down to their respective associated vertical supports 4, since they are slidably mounted there in the vertical direction.
Aufgrund der Hydraulikzylinder 20, 21, 22, 23, die jeweils beliebig mit Hydraulikflüssigkeit beaufschlagbar sind, kann der Spreader 6 in Bezug auf das Rahmengestell 2 und damit in Bezug auf den Portalhubwagen 1 quasi beliebig sowohl in Due to the hydraulic cylinder 20, 21, 22, 23, each of which can be acted upon arbitrarily with hydraulic fluid can the spreader 6 with respect to the frame 2 and thus with respect to the straddle carrier 1 almost arbitrarily both in
Fahrtrichtung des Portalhubwagens 1 als auch in der dazu senkrechten Querrichtung positioniert werden; der Portalhub- wagen 1 muss für diese Feinpositionierung des Spreaders 6, die in beiden Richtungen einer Horizontalebene erfolgen kann, nicht bewegt werden. Hierdurch lassen sich aufwändige Fahrmanöver des Portalhubwagens 1 bei der Feinpositionierung des Spreaders 6 oberhalb eines Containers 8 bzw. bei der Feinpo- sitionierung eines am Spreader 6 hängenden Containers 8 vermeiden . Direction of travel of the straddle carrier 1 and in the perpendicular transverse direction are positioned; The straddle carrier 1 does not have to be moved for this fine positioning of the spreader 6, which can take place in both directions of a horizontal plane. In this way, complex driving maneuvers of the straddle carrier 1 during the fine positioning of the spreader 6 above a container 8 or during the fine positioning of a container 8 suspended on the spreader 6 can be avoided.
Die quasi beliebige Positionierbarkeit des Spreaders 6 inner¬ halb des Rahmengestells 2 geht am besten aus den Figuren 4 und 5 hervor. The quasi arbitrary positionability of the spreader 6 within ¬ half of the frame 2 is best shown in Figures 4 and 5.
In den gezeigten Ausführungsbeispielen ist an den Hydraulikzylindern 20, 21, 22, 23 der Positioniervorrichtung ein Grenzdruck einstellbar, bei dessen Erreichen bzw. Überschrei- ten die Hydraulikzylinder 20, 21, 22, 23 Hydraulikfluid ab¬ blasen. Hierdurch kann sichergestellt werden, dass es bei ei¬ nem Zusammenstoß eines Containers 8 mit einem Hindernis zu einer zumindest teilweisen Stoßabsorption kommt. Irgendwelche Beschädigungen etc. des Containers 8 bzw. des Portalhubwagens oder desjenigen Gegenstands, gegen den der Container 8 stößt, lassen sich hierdurch - wenn nicht vermeiden - so doch erheb¬ lich reduzieren. In the embodiments shown, a limit pressure on the hydraulic cylinders 20, 21, 22, 23 of the positioning device adjustable, 21 when it is reached or exceeded th the hydraulic cylinders 20, 22, 23 hydraulic fluid blown from ¬. This can ensure that there is at ei ¬ nem collision of a container 8 with an obstacle to an at least partial absorption of shock. Any damage etc. of the container 8 or the straddle carrier or that of the object against which the container 8 comes, can be thus - if not prevent - then at least reduce uplifting ¬ Lich.
Die Hydraulikzylinder 20, 21, 22, 23 sind üblicherweise mit dem freien Ende ihres Hubglieds 26 mit dem stüt zenseitigen Gleitgelenk 25 verbunden; grundsätzlich ist es auch möglich, wie dies in Figur 5 am dort rechten unteren Eckbereich 18 beispielhaft gezeigt ist, dass der Hydraulikzylinder 23 mit seinem Hubglied 26 an dem spreaderseitigen Gelenk 24 sitzt. The hydraulic cylinders 20, 21, 22, 23 are usually connected to the free end of its lifting member 26 with the stut zenseitigen slip joint 25; In principle, it is also possible, as shown in FIG. 5, at the lower right corner area 18 is shown as an example that the hydraulic cylinder 23 is seated with its lifting member 26 on the spreaderseitigen joint 24.
Zum Schutz der Hydraulikzylinder 20, 21, 22, 23 gegen mittels dieser kaum bzw. nicht aufnehmbaren Querkräften können die Hydraulikzylinder, wie dies in Figur 4 gezeigt ist, mit jeweils einer Teleskopeinrichtung 27 versehen sein. Die Teleskopeinrichtung 27 umhüllt den ihr zugeordneten Hydraulikzylinder 20, 21, 22 bzw. 23 quasi formschlüssig, und zwar ins- besondere und in jedem Fall in demjenigen Bereich des Hydraulikzylinders 20, 21, 22, 23, in dem das Hubglied 26 desselben austritt. Hierdurch kann ein Abknicken oder eine ähnliche Be¬ schädigung des Hydraulikzylinders 20, 21, 22, 23 zuverlässig vermieden werden. In order to protect the hydraulic cylinders 20, 21, 22, 23 against transverse forces that are barely or not absorbable by means of the latter, the hydraulic cylinders, as shown in FIG. 4, can each be provided with a telescopic device 27. The telescopic device 27 encloses the hydraulic cylinders 20, 21, 22 or 23 assigned to it virtually in a form-fitting manner, specifically and in any case in that region of the hydraulic cylinder 20, 21, 22, 23 in which the lifting member 26 thereof exits. This allows a bending or a similar Be ¬ damage of the hydraulic cylinder 20, 21, 22, 23 are reliably avoided.
Mittels der Teleskopeinrichtungen 27 sind die auf die Hydrau¬ likzylinder 20, 21, 22, 23 beim Betrieb des Portalhubwagens 1 bzw. des Spreaders 6 in Querrichtung auftretenden Kräfte aufnehm- und ableitbar. By means of the telescoping devices 27, the pick-6 forces occurring transversely to the Hydrau ¬ likzylinder 20, 21, 22, 23 during operation of the straddle carrier 1 and the spreader and derivable.
Anstelle der Teleskopeinrichtungen 27 sind im Falle des in Figur 5 gezeigten Ausführungsbeispiels des Spreaders 6 Knickarmeinrichtungen 28 vorgesehen, von denen jeweils eine jedem Hydraulikzylinder 20, 21, 22, 23 zugeordnet ist. Auch mittels dieser Knickarmeinrichtungen 28 lassen sich in Querrichtung der Hydraulikzylinder 20, 21, 22, 23 auf diese einwirkende Kräfte aufnehmen und ableiten. Instead of the telescopic devices 27 6 Knickarmeinrichtungen 28 are provided in the case of the embodiment of the spreader shown in Figure 5, of which each one hydraulic cylinder 20, 21, 22, 23 is associated. Also by means of these Knickarmeinrichtungen 28 can be in the transverse direction of the hydraulic cylinder 20, 21, 22, 23 absorb and dissipate acting on these forces.
