Description

Die vorliegende Erfindung betrifft eine Stapelvorrichtung für Gittermastkranelemente, insbesondere für Auslegerstücke eines Krans. Gegenwärtig wird zum Lagern von Gittermastkränen bzw. deren miteinander montierbaren Abschnitten viel Lagerplatz benötigt.The present invention relates to a stacking device for lattice boom crane elements, in particular for boom sections of a crane. A lot of storage space is currently required for storing lattice boom cranes or their sections that can be assembled with one another.

Aus der US 2020/0062557 A1 ist ein System zum Stapeln von Gittermastkranelementen bekannt, umfassend einen ersten Auflagekörper, wobei der ersten Auflagekörper an seiner Bodenfläche eine konkav verlaufende durchgängige Mulde aufweist, um einen Längsträger eines Gittermastkranelements aufzunehmen. Dieses System ist anwendbar nur bei Elementen gleicher Größe.From the US 2020/0062557 A1 a system for stacking lattice boom crane elements is known, comprising a first support body, the first support body having a concave, continuous trough on its bottom surface in order to accommodate a longitudinal beam of a lattice boom crane element. This system is only applicable to elements of the same size.

Dies führt dazu, dass Gittermastkranelemente, die in Querschnittrichtung gesehen einen unterschiedlichen Durchmesser haben, nicht aufeinandergestapelt werden können. Somit wird trotz der Möglichkeit immer noch relativ viel Fläche beansprucht, wenn man diese Elemente lagern möchte. Lagert man bspw. zwei Krane unterschiedlicher Hersteller, ist deren Auslegerdurchmesser in der Regel nicht gleich, so dass für jeden Auslegerabschnitt der beiden Kräne ein separater Lagerplatz gefunden werden muss. Zudem ist es erforderlich für jeden der unterschiedlichen Krane eine eigene Stapelvorrichtung vorzuhalten, die exklusiv für einen zugehörigen Krantyp verwendet wird.The result of this is that lattice boom crane elements, which have different diameters when viewed in the cross-sectional direction, cannot be stacked on top of one another. Thus, despite the possibility, a relatively large amount of space is still required if you want to store these elements. If, for example, two cranes from different manufacturers are stored, their jib diameter is usually not the same, so that a separate storage location must be found for each jib section of the two cranes. In addition, it is necessary to have a separate stacking device for each of the different cranes, which is used exclusively for an associated type of crane.

Es ist das Ziel der vorliegenden Aufgabe eine Stapelvorrichtung zu schaffen, die das Stapeln von Gittermastkranelementen unterschiedlichen Durchmessers erlaubt, was zu einer weiteren Verringerung der Lagerfläche beim Lagern von Kranen unterschiedlichen Typs oder beim Lagern eines Krans mit Elementen, die einen unterschiedlichen Durchmesser aufweisen, führt.The aim of the present task is to create a stacking device that allows stacking of lattice boom crane elements of different diameters, which leads to a further reduction of the storage area when storing cranes of different types or when storing a crane with elements that have different diameters.

Dies gelingt mit einer Stapelvorrichtung, die sämtliche Merkmale des unabhängigen Anspruchs 1 aufweist. Vorteilhafte Ausgestaltungen der Stapelvorrichtung sind in den abhängigen Unteransprüchen aufgeführtThis is achieved with a stacking device that has all the features of independent claim 1 . Advantageous configurations of the stacking device are listed in the dependent claims

Nach der Erfindung ist demnach vorgesehen, dass die Stapelvorrichtung für Gittermastkranelemente, insbesondere für Auslegerstücke einen ersten Auflagekörper, eine Profilschiene, und einen zweiten Auflagekörper umfasst, wobei der ersten Auflagekörper an seiner Bodenfläche eine konkav verlaufende durchgängige Mulde aufweist, um einen Längsträger eines Gittermastkranelements aufzunehmen bzw. sich dort abzustützen, und an seiner zur Bodenfläche gegenüberliegenden Deckenfläche einen Kopplungsabschnitt zum verschieblichen Befestigen an der Profilschiene aufweist, und der zweite Auflagekörper an seiner Deckenfläche eine konkav verlaufende durchgängige Mulde aufweist, um einen Längsträger eines Gittermastkranelements aufzunehmen, und an seiner zur Deckenfläche gegenüberliegenden Bodenfläche einen Kopplungsabschnitt zum verschieblichen Befestigen an der Profilschiene aufweist.According to the invention, it is therefore provided that the stacking device for lattice boom crane elements, in particular for boom sections, comprises a first support body, a profile rail, and a second support body, with the first support body having a concave, continuous trough on its bottom surface in order to accommodate or hold a longitudinal beam of a lattice boom crane element to be supported there, and on its top surface opposite to the bottom surface has a coupling section for displaceable attachment to the profile rail, and the second support body has a concave continuous trough on its top surface in order to accommodate a longitudinal beam of a lattice boom crane element, and on its bottom surface opposite to the top surface has a coupling section for displaceable attachment to the profile rail.

Der erste Auflagekörper kann dabei auf ein am Boden angeordnetes Gittermastkranelement, bspw. ein Auslegerstück eines Krans, angeordnet werden. Hierzu wird die konkav verlaufende Mulde (also eine Mulde, die zum Inneren des ersten Auflagekörpers verläuft) des ersten Gittermastkranelements auf einen Längsträger des am Boden angeordneten Gittermastkranelements aufgesetzt, so dass die Deckenfläche des ersten Auflagekörpers nach oben hin wegsteht. Diese Deckenfläche ist über ihren Kopplungsabschnitt mit der Profilschiene gekoppelt und zwar in der Regel so, dass der erste Auflagekörper nur noch entlang der Längsrichtung der Profilschiene bewegt werden kann. An der zum ersten Auflagekörper abgewandten Seite der Profilschiene ist auf ähnliche Art und Weise der zweite Auflagekörper mit der Profilschiene in Kontakt. Auch hier ist der Kopplungsabschnitt so an der Profilschiene angeordnet, dass in der Regel nur eine Verschiebebewegung in Längsrichtung der Profilschiene möglich ist. An der von der Profilschiene abgewandten Deckenfläche des zweiten Auflagekörpers ist dann wiederum eine konkave Mulde zum Aufnehmen eines Längsträgers eines Gittermastkranelements vorgesehen. Die konkave Mulde ist eine zum Inneren des zweiten Auflagekörpers hin verlaufende bogenförmige Kontur, die sich durchgängig über den gesamten Körper hinweg erstreckt. Dabei ist es von Vorteil, wenn die Mulde des ersten Auflagekörpers im Wesentlichen identisch oder identisch zur Mulde des zweiten Auflagekörpers ist.The first support body can be arranged on a lattice mast crane element arranged on the ground, for example a jib section of a crane. For this purpose, the concave trough (i.e. a trough that runs to the inside of the first support body) of the first lattice boom crane element is placed on a longitudinal beam of the lattice boom crane element arranged on the ground, so that the top surface of the first support body protrudes upwards. This ceiling surface is coupled via its coupling section with the rail, usually in such a way that the first support body only along the Can be moved longitudinally of the rail. On the side of the profile rail facing away from the first support body, the second support body is in contact with the profile rail in a similar way. Here, too, the coupling section is arranged on the profile rail in such a way that, as a rule, only a displacement movement in the longitudinal direction of the profile rail is possible. A concave trough for receiving a longitudinal beam of a lattice boom crane element is then in turn provided on the top surface of the second support body facing away from the profile rail. The concave trough is an arcuate contour extending toward the interior of the second pad body and extending continuously throughout the body. It is advantageous if the trough of the first support body is essentially identical or identical to the trough of the second support body.

Soll nun in die Mulde des (oberen) zweiten Auflagekörpers ein Gittermastkranelement abgelegt werden, dessen Durchmesser zu dem darunter angeordneten verschieden ist, kann der (obere) zweite Auflagekörper einfach entlang der Profilschiene in entsprechender Art und Weise verschoben werden, so dass auch das Stapeln eines solchen im Querschnittsdurchmesser verschiedenen Elements möglich ist.If a lattice boom crane element is now to be placed in the trough of the (upper) second support body, the diameter of which differs from that arranged underneath, the (upper) second support body can simply be moved along the profile rail in a corresponding manner, so that stacking a such element different in cross-sectional diameter is possible.

Nach der Erfindung kann vorgesehen sein, dass die Profilschiene aus Aluminium besteht.According to the invention it can be provided that the rail consists of aluminum.

Ferner kann vorgesehen sein, dass die Profilschiene umlaufend mit mindestens einer nach innen ragenden Einbuchtung versehen ist, um das verschiebliche Befestigen der Profilschiene mit dem ersten Auflagekörper und dem zweiten Auflagekörper zu ermöglichen.Provision can also be made for the profile rail to be provided with at least one inwardly projecting indentation all around, in order to enable the profile rail to be slidably fastened to the first support body and the second support body.

Dabei kann vorgesehen sein, dass die Profilschiene in ihrem Querschnitt eine im Wesentlichen rechteckige, vorzugsweise eine im Wesentlichen quadratische Grundstruktur aufweist.Provision can be made here for the profile rail to have an essentially rectangular, preferably essentially square, basic structure in its cross section.

Nach einer optionalen Modifikation der vorliegenden Erfindung kann vorgesehen sein, dass der Kopplungsabschnitt des ersten Auflagekörpers und der Kopplungsabschnitt des zweiten Auflagekörpers jeweils Eingreifelemente zum Hintergreifen eines Profils der Profilschiene aufweist.According to an optional modification of the present invention, it can be provided that the coupling section of the first support body and the coupling section of the second support body each have engagement elements for engaging behind a profile of the profile rail.

Mit diesen Eingreifelementen greift der jeweilige Auflagekörper in ein zugehöriges Profil der Profilschiene ein, so dass nur noch ein Bewegen des Auflagekörpers entlang der Längsrichtung der Profilschiene möglich ist. Die Auflagekörper werden also auf die Profilschiene aufgeschoben.With these engagement elements, the respective support body engages in an associated profile of the profile rail, so that the support body can only be moved along the longitudinal direction of the profile rail. The support bodies are thus pushed onto the profile rail.

Nach einer weiteren optionalen Fortbildung der Erfindung kann vorgesehen sein, dass der erste Auflagekörper und der zweite Auflagekörper gleichzeitig an der Profilschiene befestigbar sind, wobei vorzugsweise hierfür unterschiedliche Profile der Profilschiene vorgesehen sind.According to a further optional development of the invention, it can be provided that the first support body and the second support body can be fastened to the profile rail at the same time, with different profiles of the profile rail preferably being provided for this purpose.

Diese Profile liegen vorzugsweise an gegenüberliegenden Seiten der Profilschiene.These profiles are preferably on opposite sides of the rail.

Vorzugsweise ist in einem verbundenen Zustand von Profilschiene mit mindestens einem der beiden Auflagekörper, die Längsrichtung der Profilschiene quer zur Verlaufsrichtung der Mulde des Auflagekörpers angeordnet. Die Profilschiene verläuft also quer zu einem in der Mulde eingelegten Längsträger des Gittermastkranelements.In a connected state of the profile rail with at least one of the two support bodies, the longitudinal direction of the profile rail is preferably arranged transversely to the direction of the trough of the support body. The profile rail thus runs transversely to a longitudinal beam of the lattice boom crane element that is inserted in the trough.

Zudem kann nach der Erfindung vorgesehen sein, dass der erste Auflagekörper und/oder der zweite Auflagekörper aus einem Kunststoff, einem Verbundwerkstoff, einem Elastomer und/oder einem Gummi ist/sind.In addition, it can be provided according to the invention that the first support body and/or the second support body is/are made of a plastic, a composite material, an elastomer and/or a rubber.

Vorzugsweise weist der zweite Auflagekörper in seiner in der Deckenfläche angeordneten Mulde eine an einem Muldengrund verlaufende Nut auf, um bei einem Aufnehmen eines Längsträgers in der Mulde sich ansammelndes Wasser abzuführen.The second support body preferably has, in its trough arranged in the top surface, a groove running on a trough base in order to drain away water that collects when a longitudinal member is picked up in the trough.

Dabei ist also im unteren Bereich der Mulde eine weitere in der Mulde verlaufende Nut vorgesehen, um eventuell sich dort ansammelndes Wasser ableiten zu können. Bei um den Gefrierpunkt schwankenden Temperaturen kann demzufolge wiederholt gefrierendes Wasser nicht zu einer Beschädigung des in die Mulde eingelegten Längsträgers führen.In this case, a further groove running in the trough is provided in the lower area of the trough, in order to be able to drain off any water that collects there. As a result, when temperatures fluctuate around freezing point, repeated freezing water cannot damage the longitudinal member inserted in the trough.

Zudem kann vorgesehen sein, dass das verschiebliche Befestigen des ersten Auflagekörpers und/oder des zweiten Auflagekörpers an der Profilschiene über ein Aufschieben des jeweiligen Kopplungsabschnitts auf die Profilschiene erfolgt, so dass der aufgeschobene Auflagekörper nur noch entlang der Längsrichtung der Profilschiene bewegt werden kann.Provision can also be made for the first support body and/or the second support body to be slidably fastened to the profile rail by sliding the respective coupling section onto the profile rail, so that the support body that has been pushed on can only be moved in the longitudinal direction of the profile rail.

Weiter kann nach der Erfindung vorgesehen sein, dass der Kopplungsabschnitt des ersten Auflagekörpers identisch ist mit dem Kopplungsabschnitt des zweiten Auflagekörpers.Furthermore, it can be provided according to the invention that the coupling section of the first support body is identical to the coupling section of the second support body.

Nach einer weiteren optionalen Modifikation der vorliegenden Erfindung kann vorgesehen sein, dass der Kopplungsabschnitt des ersten Auflagekörpers und/oder des zweiten Auflagekörpers Eingreifhaken zum Eingreifen in ein Profil der Profilschiene aufweist.According to a further optional modification of the present invention, it can be provided that the coupling section of the first support body and/or the second support body has engagement hooks for engaging in a profile of the profile rail.

Vorzugsweise ist die Distanz von der Bodenfläche zu der Deckenfläche des mindestens einen ersten Auflagekörpers größer als die Distanz von der Bodenfläche zu der Deckenfläche des mindestens einen zweiten Auflagekörpers, vorzugsweise mindestens doppelt so groß, bevorzugterweise mindestens dreimal so groß.The distance from the bottom surface to the top surface of the at least one first support body is preferably greater than the distance from the bottom surface to the top surface of the at least one second support body, preferably at least twice as large, preferably at least three times as large.

So ist es auf einfache Art und Weise möglich, die benötigte Höhe zu erreichen, die erforderlich ist, um die bspw. am Ausleger befestigten Elemente wie Haltestangen oder dergleichen zu überragen.It is thus possible in a simple manner to reach the required height, which is required in order to tower over the elements such as handrails or the like fastened to the boom, for example.

Weiter kann nach der Erfindung vorgesehen sein, dass mindestens zwei erste Auflagekörper, eine Profilschiene und mindestens zwei zweite Auflagekörper vorgesehen sin, wobei die mindestens zwei ersten Auflagekörper und die mindestens zwei zweiten Auflagekörper über ihren jeweiligen Kopplungsabschnitt an derselben Profilschiene angeordnet sind.According to the invention, it can further be provided that at least two first support bodies, a profile rail and at least two second support bodies are provided, the at least two first support bodies and the at least two second support bodies being arranged on the same profile rail via their respective coupling section.

Dabei kann vorgesehen sein, dass die mindestens zwei ersten Auflagekörper an einer ersten Seite der Profilschiene und die mindestens zwei zweiten Auflagekörper an einer zweiten Seite der Profilschiene angeordnet sind.It can be provided that the at least two first support bodies are arranged on a first side of the profile rail and the at least two second support bodies are arranged on a second side of the profile rail.

Vorzugsweise sind die mindestens zwei ersten Auflagekörper jeweils in ein und dasselbe erste Profil der Profilschiene und die mindestens zwei zweiten Auflagekörper jeweils in ein und dasselbe zweite Profil der Profilschiene eingeführt.Preferably, the at least two first support bodies are each introduced into one and the same first profile of the profile rail and the at least two second support bodies are each introduced into one and the same second profile of the profile rail.

Fig. 1 zeigt eine Darstellung der erfindungsgemäßen Stapelvorrichtung 1 zusammen mit einem Gittermastkranelement 2 in einer Seitenansicht. Die Stapelvorrichtung 1 wird auf die vom Boden abgewandte Seite des Gittermastkranelements 2 angeordnet, so dass weitere Gittermastkranelemente aufgestapelt werden können. Um dies zu ermöglichen ist an der Oberseite des Gittermastkranelements 2, bspw. eines Auslegerabschnitts eines Gittermastkrans, die erfindungsgemäße Stapelvorrichtung 1 vorgesehen. Diese umfasst zwei erste Auflagekörper 3, die jeweils mit unterschiedlichen der parallel zueinander verlaufenden Längsträger 25 des Gittermastkranelements 2 zusammenwirken. Beide der ersten Auflagekörper 3 werden mit einer Profilschiene 4 verbunden, an dessen Oberseite mindestens zwei zweite Auflagekörper 5 angeordnet sind. 1 shows a representation of the stacking device 1 according to the invention together with a lattice boom crane element 2 in a side view. The stacking device 1 is on the side facing away from the ground Lattice boom crane element 2 arranged so that more lattice boom crane elements can be stacked. In order to make this possible, the stacking device 1 according to the invention is provided on the upper side of the lattice boom crane element 2, for example a boom section of a lattice boom crane. This comprises two first support bodies 3, which each interact with different longitudinal beams 25 of the lattice boom crane element 2 running parallel to one another. Both of the first support bodies 3 are connected to a profile rail 4, on the upper side of which at least two second support bodies 5 are arranged.

In der vorliegenden Fig. 1 sind die Bestandteile in einer Explosionsdarstellung gezeigt, um das Verständnis der Erfindung zu vereinfachen.In the present 1 The components are shown in an exploded view to facilitate understanding of the invention.

Man erkennt, dass die ersten Auflagekörper 3 unterschiedlich zu den zweiten Auflagekörpern 5 ausgebildet sein können. Diese können in Höhenrichtung länger sein, damit die quer verlaufende Profilschiene 4 nicht mit Anbauteilen des Gittermastkranelements 4, vorliegend eine Haltestange 24, kollidiert.It can be seen that the first support bodies 3 can be designed differently from the second support bodies 5 . These can be longer in the height direction, so that the profile rail 4 running transversely does not collide with add-on parts of the lattice boom crane element 4, in this case a retaining rod 24.

Mit der vorliegenden Erfindung ist es auch möglich, Gittermastkranelemente 21, 22, 23 unterschiedlichen Durchmessers zu stapeln. Dazu werden die jeweiligen Auflagekörper 3, 5 einfach so entlang der Profilschiene 4 verschoben, bis sie an der entsprechenden Stelle zum Aufnehmen eines Längsträgers eines Gittermastkranelements 21, 22, 23 angeordnet sind. Vorteil an der Erfindung ist, dass die an gegenüberliegenden Seite der Profilschiene 4 angeordneten Auflagekörper 3, 5 unabhängig voneinander entlang der Längsrichtung des Profilschiene 4 verschoben werden können.With the present invention it is also possible to stack lattice boom crane elements 21, 22, 23 of different diameters. For this purpose, the respective support bodies 3, 5 are simply pushed along the profile rail 4 until they are arranged at the appropriate point for receiving a longitudinal beam of a lattice boom crane element 21, 22, 23. The advantage of the invention is that the support bodies 3, 5 arranged on the opposite side of the profile rail 4 can be displaced independently of one another along the longitudinal direction of the profile rail 4.

Die Figs. 3a und 3b zeigen eine Ansicht der Quer- und der Längsseite der erfindungsgemäßen Stapelvorrichtung 1 in einem nicht zusammengefügten Zustand.the figs 3a and 3b show a view of the transverse and the longitudinal side of the stacking device 1 according to the invention in a non-assembled state.

In Fig. 3a erkennt man die Profilschiene 4 in einer Querschnittsansicht, so dass man deren Einbuchtungen 41 erkennen kann, die das Profil der Profilschiene bilden. Die beiden Kopplungsabschnitte 32, 52 der Auflagekörper 3, 5 sind jeweils mit Eingreifhaken 321, 521 versehen, die dazu ausgelegt sind, in entsprechende Einbuchtungen 41 der Profilschiene 4 derart einzugreifen, dass die Auflagekörper 3, 5 nur entlang der Längsrichtung der Profilschiene 4 bewegt werden können. Eine dazu abweichende Bewegung ist aufgrund des Eingreifens der Eingreifhaken 321, 521 in dafür vorgesehene Einbuchtungen 41 nicht möglich.In Figure 3a one recognizes the profile rail 4 in a cross-sectional view, so that one can see the indentations 41 which form the profile of the profile rail. The two coupling sections 32, 52 of the support bodies 3, 5 are each provided with engagement hooks 321, 521, which are designed to engage in corresponding indentations 41 of the profile rail 4 in such a way that the support bodies 3, 5 are only moved along the longitudinal direction of the profile rail 4 be able. A movement deviating from this is not possible due to the engagement of the engagement hooks 321, 521 in indentations 41 provided for this purpose.

Der Kopplungsabschnitt 32, 52 kann dabei zusammen mit den jeweiligen Eingreifhaken 321, 521 einen Hinterschnitt bilden, so dass die Auflagekörper 3, 5 auf die Profilschiene 4 aufgeschoben werden muss.The coupling section 32, 52 can form an undercut together with the respective engagement hooks 321, 521, so that the support bodies 3, 5 have to be pushed onto the profile rail 4.

Fig. 3b zeigt eine Längsseite der Profilschiene 4 und entsprechend ausgerichtete Auflagekörper 3, 5. Man erkennt, dass die Mulden 31, 51 der Auflagekörper 3, 5 quer zur Längsrichtung der Profilschiene 4 verlaufen und zum Einlegen eines Längsträgers 25 einer Gittermastkranelements 2 dienen. Figure 3b shows a longitudinal side of the profile rail 4 and correspondingly aligned support bodies 3, 5. It can be seen that the troughs 31, 51 of the support bodies 3, 5 run transversely to the longitudinal direction of the profile rail 4 and are used to insert a longitudinal beam 25 of a lattice boom crane element 2.

Der Muldengrund des zweiten Auflagekörpers 5 weist dabei eine Nut 512 auf, um sich möglicherweise in der Mulde 51 ansammelndes Wasser abführen zu können.The base of the trough of the second support body 5 has a groove 512 in order to be able to drain off any water that may have accumulated in the trough 51 .

Auch wenn nicht dargestellt, kann eine solche Nut auch in der Mulde 31 des ersten Auflagekörpers 3 vorgesehen sein.Even if not shown, such a groove can also be provided in the trough 31 of the first support body 3 .
