Description

Die Erfindung bezieht sich auf eine Haltevorrichtung für Lasten mit einem Flansch, wobei die Haltevorrichtung mindestens eine unter dem Flansch an einer Unterseite des Flansches anordenbare Auflagefläche aufweist. Derartige Vorrichtungen sind seit mehreren Jahren bekannt, so aus der DE 10 2011 011 603 A1 , der EP 2 402 278 A1 und der EP 2 661 408 .The invention relates to a holding device for loads with a flange, wherein the holding device has at least one can be arranged under the flange on an underside of the flange bearing surface. Such devices have been known for several years, so from the DE 10 2011 011 603 A1 , of the EP 2 402 278 A1 and the EP 2 661 408 ,

Im Zusammenhang mit dem Einsatz der bekannten Haltevorrichtungen hat sich herausgestellt, dass es bei immer größer werdenden Lasten zu einer starken Beanspruchung der Last im Bereich des Anschlusses des Flansches an die Wand, so die Mantelfläche, kommt. Werden beispielsweise röhrenförmige lang gestreckte Lasten, die zumindest an einer Stirnseite einen Flansch aufweisen, transportiert, kann es im Zusammenhang mit dem Transportvorgang zu Deformationen in dem vorbeschriebenen Bereich kommen.In connection with the use of the known holding devices has been found that with ever increasing loads to a heavy load on the load in the area of the connection of the flange to the wall, so the lateral surface comes. If, for example, tubular elongate loads which have a flange at least on one end face are transported, deformations in the above-described range may occur in connection with the transport process.

Zu beachten ist dabei, dass derartige röhrenförmige lang gestreckte Lasten in der Regel waagerecht am Boden gelagert werden. Wird eine bekannte Vorrichtung an einem Flansch angeschlagen, so kommt es schon beim Aufrichten der Röhren in eine senkrechte Lage zu erheblichen Beanspruchungen des vorbeschriebenen Bereichs des Flansches / Mantelfläche. Bei einem Transport, insbesondere dann, wenn die Last zu schwingen beginnt, kommt es vermehrt zu Deformationen im Bereich des Flansches / Mantelfläche. So wird der Flansch in dem Bereich, an dem er an der Mantelfläche angeordnet ist, aufgebogen. Dies hatte man in der Vergangenheit dadurch zu verhindern versucht, dass über einen Hebelmechanismus wirkende Klemmmittel eingesetzt werden, welche auf den Flansch oberhalb seiner Auflagefläche auf eine Haltevorrichtung einwirken, EP 2 661 408 B1 .
Der Nachteil dieser Lösung besteht darin, dass die Vorrichtung nur bei senkrechter Lage ihre Wirkung entfaltet und nicht bei einem Aufrichten einer entsprechenden Last. Darüber hinaus besteht die Gefahr, dass bei dynamischen Bewegungen der Last die bekannte Vorrichtung nicht ihre volle Wirkung entfaltet. Darüber hinaus sind je nach Art der zu transportierenden Lasten, so je nach Art der Dicke der Wand der Last unterschiedliche Hebelvorrichtungen einzusetzen, weil sich das Hebelverhältnis ändert. So variiert der in der EP 2 661 408 A1 in Fig. 2 dargestellte Wert y, wenn beispielsweise die Wanddicke der Last zu- oder abnimmt. Ändert sich jedoch dieses Verhältnis, so wird der Flansch entweder mit zu wenig oder zu viel Kraft durch das Klemmmittel beaufschlagt.It should be noted that such tubular elongate loads are usually stored horizontally on the ground. If a known device is struck on a flange, it already comes when erecting the tubes in a vertical position to considerable stresses of the above-described area of the flange / lateral surface. During transport, in particular when the load begins to oscillate, deformations in the area of the flange / lateral surface are increasingly occurring. Thus, the flange is bent in the region where it is arranged on the lateral surface. This had been tried in the past to prevent it by acting on a lever mechanism clamping means are used, which act on the flange above its support surface on a holding device, EP 2 661 408 B1 ,
The disadvantage of this solution is that the device develops its effect only in a vertical position and not at an erection of a corresponding load. In addition, there is the Danger that during dynamic movements of the load, the known device does not develop its full effect. In addition, depending on the type of loads to be transported, so depending on the type of thickness of the wall of the load to use different lever devices, because the lever ratio changes. So varies in the EP 2 661 408 A1 in Fig. 2 shown value y, for example, if the wall thickness of the load increases or decreases. However, if this ratio changes, the flange will either be subjected to too little or too much force by the clamping means.

Aufgabe der Erfindung ist es daher, eine Haltevorrichtung für einen Transport entsprechender Lasten mit einem Flansch, so beispielsweise röhrenförmige Pfähle, bereitzustellen, bei der ein Aufbiegen eines Flansches einer zu transportierenden Last vermindert wird.The object of the invention is therefore to provide a holding device for transporting corresponding loads with a flange, such as tubular piles, in which a bending of a flange of a load to be transported is reduced.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Hauptanspruchs 1 und des unabhängigen Nebenanspruchs 11 gelöst, wobei die Unteransprüche weitere erfindungsgemäße Ausgestaltungsvarianten dieser Lösungen beinhalten.This object is achieved by the features of the main claim 1 and the independent subsidiary claim 11, wherein the dependent claims include further inventive embodiments of these solutions.

Danach weist die Haltevorrichtung für eine Last, einen an mindestens einem Ende angeordneten Flansch, der in Regel - aber nicht erfindungsnotwendig - umlaufend ausgestaltet ist, folgende Merkmale auf.Thereafter, the holding device for a load, a arranged at least one end of the flange, which is designed in a rule - but not erfindungsnotwendig - circumferentially, the following features.

Die Haltevorrichtung ist in bekannter Weise an ein kranartiges Hebezeug anordenbar und weist mindestens zwei, vorzugsweise drei, an einer Unterseite des Flansches, last- bzw. rohrinnenseitig, in einem gleichen Winkel zueinander den Flansch umlaufend und somit an die Last anordenbare und arretierbare Auflageflächen auf, wobei an der Haltevorrichtung mindestens ein Niederhalter, korrespondierend je Auflagefläche, vorgesehen ist und durch den jeweiligen Niederhalter eine Oberseite des Flansches und/oder ein an den Flansch sich anschließender Mantelbereich mit einer von einem Transportvorgang, so einem Heben, unabhängigen Kraft beaufschlagbar ist und/oder ein von dem Transportvorgang unabhängiger Formschluss zwischen Haltevorrichtung und Flansch herstellbar ist, wobei im Rahmen der Erfindung vorzugsweise durch den jeweiligen Niederhalter die Oberseite des Flansches mit einer vom Transportvorgang unabhängigen Kraft beaufschlagbar ist. Im Rahmen der Erfindung ist gelegen, die drei vorgenannten Varianten jeweils einzeln oder in Kombination anzuwenden, so auch gemischt an einer Haltevorrichtung. So kann es beispielsweise vorteilhaft sein, dass an einer, bei waagerechter Lage der Last, der Erdoberfläche zugewandten Auflagefläche durch den Niederhalter ein von dem Transportvorgang unabhängiger Formschluss zwischen Haltevorrichtung und Flansch herstellbar ist, was vorteilhaft bei einem Aufrichten der Last in eine senkrechte Lage sein kann. Zusätzlich ist sodann - wie an weiteren Auflageflächen ausschließlich vorgesehen - durch den dazu korrespondierenden Niederhalter die Oberseite des Flansches mit einer vom Transportvorgang unabhängigen Kraft beaufschlagbar.The holding device can be arranged in a known manner on a crane-like hoist and has at least two, preferably three, on an underside of the flange, on the load or pipe inside, at an equal angle to each other around the flange and thus can be arranged on the load and lockable bearing surfaces, wherein on the holding device at least one hold-down, corresponding per support surface, is provided and acted upon by the respective hold-down an upper surface of the flange and / or a flange adjacent to the jacket region with one of a transport process, such a lifting, independent force is and / or independent of the transport process positive connection between the holding device and flange can be produced, in the context of the invention preferably by the respective hold-down the top of the flange with a force independent of the transport process force can be acted upon. In the context of the invention is convenient to apply the three aforementioned variants each individually or in combination, as well as mixed on a holding device. Thus, it may be advantageous, for example, that at one, in a horizontal position of the load, the ground surface facing support surface by the hold-down independent of the transport process positive connection between the holding device and flange can be produced, which can be advantageous when erecting the load in a vertical position , In addition, the top side of the flange can then be acted upon by a force independent of the transport process, as is exclusively provided on further support surfaces, by the corresponding hold-down device.

Eine vom Transportvorgang unabhängige Kraft ist dabei nicht eine solche, die, wie beispielsweise aus der EP 2 661 408 A1 folgend, durch die Lage und das Eigengewicht der Last erzeugt wird, so wie bei einem Hängen der Last am Haken und die somit vertikal wirkenden Zugkräfte.A force independent of the transport process is not one that, as for example from the EP 2 661 408 A1 following, by the position and the weight of the load is generated, as in a suspension of the load on the hook and thus the vertical acting tensile forces.

Unter Last im Sinne der Erfindung sind im Wesentlichen solche Lasten zu verstehen, die beispielsweise als Gründungspfähle oder konstruktive Elemente einer Windkraftanlage dienen. Es kommen aber auch andere Lasten mit einem hohen Gewicht in Betracht, das in der Regel mehr als 1 Tonne beträgt.
Der jeweilige Niederhalter - mindestens ein Niederhalter je Auflagefläche - wird dabei unabhängig vom Hebevorgang so weit an die Oberseite des Flansches und/oder an den sich an den Flansch anschließenden Mantelbereich geführt, bis er am Flansch oder an dem den Flansch sich anschließenden Mantelbereich anliegt und auf diesen einwirkt. Die Folge ist, dass der Flansch sich nicht oder vermindert aufbiegt, wenn Kraft auf die Oberseite des Flansches wirkt, also, wenn die Last hängt oder sogar wenn die Last aus einer horizontalen in eine waagerechte Position gebracht wird. Eine Kraftbeaufschlagung des Mantelbereichs, insbesondere des äußeren Mantelbereichs, ist beim Anheben aus der horizontalen Liegeposition in eine waagerechte Position von besonderem Vorteil, weil sich so die Haltevorrichtung noch besser arretieren lässt und so auch ein Einwirken entgegen der auf die Mantelfläche wirkenden Zugkräfte möglich ist.Under load in the context of the invention are essentially those loads to understand, for example, serve as foundation piles or structural elements of a wind turbine. But there are also other loads with a high weight into consideration, which is usually more than 1 ton.
The respective hold-down - at least one hold-down per support surface - is guided so far regardless of the lifting process to the top of the flange and / or on the adjoining the flange jacket area until it rests on the flange or on the flange adjoining shell region and on this interacts. The result is that the flange does not bend or diminish when force acts on the top of the flange, that is, when the load hangs or even when the load is out of horizontal placed in a horizontal position. Applying force to the jacket region, in particular the outer jacket region, is of particular advantage when lifting from the horizontal lying position into a horizontal position, because the holding device can be arrested even better and thus acting against the tensile forces acting on the lateral surface is possible.

Die durch den jeweiligen Niederhalter beaufschlagbare Kraft weist maximal den Betrag auf, welche als statische oder dynamische Zugkraft in entgegengesetzter Richtung wirkend an der mindestens einen Auflagefläche an der Unterseite des Flansches anliegt, wenn die Last an der Haltevorrichtung hängt oder hängend schwingt, wobei die Last im Wesentlichen frei hängt.The force which can be acted upon by the respective hold-down device has a maximum of the amount which acts as a static or dynamic pulling force in the opposite direction on the at least one bearing surface on the underside of the flange, when the load is suspended from the holding device or oscillates suspended, the load being in the Essentially hanging freely.

Dabei besteht die Möglichkeit, dass die durch den jeweiligen Niederhalter beaufschlagbare notwendige Kraft mittels einer geeigneten Messvorrichtung ermittelbar ist und sodann die durch die Niederhalter beaufschlagbare Kraft dem Betrag angepasst ist, welcher als dynamische Zugkraft in entgegengesetzter Richtung wirkend an der mindestens einen Auflagefläche an der Unterseite des Flansches anliegt, wenn die Last an der Haltevorrichtung hängend schwingt. Insbesondere ist durch die Messvorrichtung ein Schwingen der Last ermittelbar. Ist die Messvorrichtung mit einer Steuerung des jeweiligen Niederhalters gekoppelt, ist dadurch die durch den jeweiligen Niederhalter ausübbare Kraft an die dynamische Zugkraft der Last anpassbar.In this case, there is the possibility that the force which can be acted upon by the respective hold-down can be determined by means of a suitable measuring device and then the force which can be acted upon by the hold-downs is adapted to the amount acting as a dynamic pulling force in the opposite direction on the at least one support surface on the underside of the Flange abuts when the load on the holding device swinging hanging. In particular, a swinging of the load can be determined by the measuring device. If the measuring device is coupled to a controller of the respective hold-down device, the force which can be exerted by the respective hold-down device can thereby be adapted to the dynamic pulling force of the load.

Der jeweilige Niederhalter ist derart an der Haltevorrichtung angeordnet, dass ein definierter Abstand zwischen einer Auflage des Flansches auf der Auflagefläche der Haltevorrichtung und einer Wirkfläche der oberhalb des Flansches durch den jeweiligen Niederhalter beaufschlagbaren Kraft besteht. Dabei ist der definierte Abstand vorzugsweise so bestimmt, dass er zur Erzeugung eines Hebels zugunsten der durch den jeweiligen Niederhalter zu beaufschlagenden Kraft führt. Zur Verhinderung des Aufbiegens des Flansches ist aufgrund des durch den definierten Abstand geschaffenen Hebels eine geringe Kraftbeaufschlagung der Oberseite des Flansches der Last notwendig.The respective hold-down device is arranged on the holding device, that there is a defined distance between a support of the flange on the support surface of the holding device and an effective surface of the above the flange acted upon by the respective hold-down force. In this case, the defined distance is preferably determined such that it leads to the generation of a lever in favor of the force to be acted upon by the respective hold-down. To prevent the bending of the Flange is due to the created by the defined distance lever a small application of force to the top of the flange of the load necessary.

Dabei sind der jeweilige Niederhalter radial und/oder die Auflageflächen der Haltevorrichtung verschiebbar.The respective hold-down are radially and / or the bearing surfaces of the holding device displaced.

Der jeweilige Niederhalter ist auf der Haltevorrichtung vorzugsweise derart verschiebbar, dass sein Abstand von der Auflagefläche und damit gleichsam von einem äußeren Mantelbereich, so der Außenseite einer Wand der Last, in Richtung zu einer Innenkante des Flansches veränderbar ist und zwar je nach Bedarf. Dadurch ist ein Hebelverhältnis, dass durch einen Abstand x, welcher sich von einer Mittellinie des Niederhalters und einer Mittellinie der Auflagefläche erstreckt, und einem Abstand y, welcher sich von der Mittellinie der Auflagefläche und einer Mittellinie der Wand der Last erstreckt, veränderbar.The respective hold-down device is preferably displaceable on the holding device in such a way that its distance from the support surface and thus, as it were, from an outer casing region, thus the outside of a wall of the load, is changeable in the direction of an inner edge of the flange, as required. Thereby, a lever ratio that is variable by a distance x, which extends from a center line of the blank and a center line of the support surface, and a distance y, which extends from the center line of the support surface and a center line of the wall of the load.

Die gedachten Mittellinien bilden den Mittelpunkt beziehungsweise das Zentrum der durch die Vorrichtung gebildeten hebelwirkenden Kräfte und dienen der einfacheren Veranschaulichung der Wirkungsweise der Vorrichtung und des Verfahrens.The imaginary center lines form the center or the center of the lever-acting forces formed by the device and serve to simplify the illustration of the operation of the device and the method.

So kann bei einer unterschiedlichen Wanddicke oder Form der Last das Hebelverhältnis angepasst werden. Ferner dient dies zur verbesserten Anordnung der Haltevorrichtung an der Last.Thus, with a different wall thickness or shape of the load, the lever ratio can be adjusted. Furthermore, this serves for improved arrangement of the holding device on the load.

Vergrößert sich nämlich der Abstand y, beispielsweise bei unterschiedlichen Mantelwanddicken der Last, so ist gleichsam der Abstand x zu vergrößern, um ein gewähltes Hebelverhältnis beizubehalten und nicht eine Kraftbeaufschlagung des Niederhalters erhöhen zu müssen. Ferner kann auch das Hebelverhältnis so geändert werden, dass der Abstand y um einen vordefinierten Wert größer ist, als der Abstand x, sodass die mittels des Niederhalters zu beaufschlagende Kraft geringer wird, um ein Aufbiegen des Flansches zu verhindern. Die Haltevorrichtung ist so auch variabler einsetzbar.Namely increases the distance y, for example, at different shell wall thicknesses of the load, so to speak, the distance x to increase to maintain a selected lever ratio and not to have to increase a force of the hold-down. Furthermore, the lever ratio can also be changed so that the distance y is greater by a predefined value than the distance x, so that the force to be acted upon by the hold-down becomes smaller in order to bend the flange to prevent. The holding device is also variable use.

In weiterer Ausgestaltung der Erfindung weist der jeweilige Niederhalter einen Stempel mit einer Stempelfläche auf. Der Stempel ist auf der Oberseite des Flansches und/oder an dem sich dem Flansch anschließenden Mantelbereich der Last mit einer Kraft beaufschlagbar. Die Stempelfläche ist auf der Oberseite des Flansches und/oder an dem sich dem Flansch anschließenden Mantelbereich anordenbar und kann somit in Abhängigkeit der Ausgestaltung des Flansches, so seiner Form, ausgeführt und angepasst werden. Im Rahmen einer möglichen Ausgestaltung der Erfindung kann der Stempel des jeweiligen Niederhalters gleichsam teilweise die Oberseite des Flansches und teilweise den sich an den Flansch anschließenden äußeren Mantelbereich abdecken, was bei einem Transport der Last von einer horizontalen in eine vertikale Position von Vorteil sein kann.In a further embodiment of the invention, the respective hold-down on a stamp with a stamp surface. The punch is acted upon by a force on the upper side of the flange and / or on the jacket region of the load adjoining the flange. The stamp surface can be arranged on the upper side of the flange and / or on the jacket region adjoining the flange and can thus be designed and adapted depending on the design of the flange, thus its shape. Within the scope of a possible embodiment of the invention, the punch of the respective hold-down can partially cover the upper side of the flange and partly the outer jacket area adjoining the flange, which may be advantageous in transporting the load from a horizontal to a vertical position.

Des Weiteren kann vorgesehen werden, dass der Flansch durch den jeweiligen mindestens einen Niederhalter formschlüssig umschließbar ist und dabei die Auflagefläche der Haltevorrichtung die Unterseite des Flansches formschlüssig aufnehmen kann. Durch einen Formschluss wird eine wesentlich größere Fläche geschaffen, an welcher die sonst nur am Flansch wirkenden Kräfte anliegen.Furthermore, it can be provided that the flange can be positively enclosed by the respective at least one hold-down device and the support surface of the holding device can receive the underside of the flange in a form-fitting manner. By a form fit a much larger area is created, against which the otherwise acting only on the flange forces.

In weiterer Ausbildung kann dabei der jeweilige Niederhalter die Oberseite des Flansches und einen sich an den Flansch anschließenden äußeren Mantelbereich der Last flächenhaft umschließen, wenn dieser in Funktion ist. Die Auflagefläche der Halterung kann dabei an der Unterseite des Flansches und einen an den Flansch sich anschließenden inneren Mantelbereich der Last flächenhaft anliegen.In a further embodiment, the respective hold-down can cover the upper side of the flange and an outer jacket region of the load adjoining the flange when it is in operation. The bearing surface of the holder can bear flat against the underside of the flange and an adjoining the flange inner shell region of the load.

Die durch den jeweiligen Niederhalter unabhängig vom Transportvorgang ausübbare Kraft ist mittels eines Aktuators gewährbar, so beispielsweise mittels einer hydraulischen Vorrichtung oder mittels eines Elektro- oder Verbrennungsmotors.The force which can be exerted by the respective hold-down device independently of the transport process can be guaranteed by means of an actuator, for example by means of a hydraulic device or by means of an electric or internal combustion engine.

In weiterer Ausgestaltung der Erfindung wird eine Befestigungsanordnung bestehend aus einer vorbeschriebenen Haltevorrichtung für Lasten mit einem Flansch und einer Last mit einem Flansch beansprucht, wobei eine Oberseite des Flansches oder ein an den Flansch sich anschließenden Mantelbereich mit einer von einem Transportvorgang, so beispielsweise einem Heben, unabhängigen Kraft beaufschlagt ist oder ein von einem Transportvorgang, so einem Heben, unabhängiger Formschluss zwischen Haltevorrichtung und Flansch hergestellt ist, wobei im Rahmen der Erfindung auch eine Kombination der drei Alternativen gelegen ist. Unter Heben ist eine Lageveränderung von einer waage- in eine senkrechte Lage zu verstehen, wie auch ein Transport in senkrechter Lage. Gleichsam sind auch alle anderen Transportlagen mitumfasst.
Gerade durch die Unabhängigkeit der Kraftbeaufschlagung des Flansches von einem Transportvorgang, so einem Heben, hebt sich die Befestigungsanordnung nachhaltig von den bekannten Vorrichtungen ab, welche nur dann Wirkung entfalten, wenn die Last senkrecht hängt.In a further embodiment of the invention, a fastening arrangement is claimed consisting of a previously described holding device for loads with a flange and a load with a flange, wherein an upper side of the flange or a jacket region adjoining the flange with one of a transport process, such as a lifting, independent force is applied or one of a transport process, so a lifting, independent positive connection between the holding device and the flange is made, wherein in the context of the invention, a combination of the three alternatives is located. Lifting is to be understood as a change in position from a horizontal to a vertical position, as well as a transport in a vertical position. Likewise, all other transport situations are included.
Just by the independence of the application of force to the flange of a transport process, such a lifting, the mounting assembly is sustainable from the known devices, which only have an effect when the load is suspended vertically.

Im Rahmen des Verfahrens ist weiterhin vorgesehen, dass die durch den mindestens einen Niederhalter beaufschlagte Kraft den Betrag annimmt, welcher als Zugkraft in entgegengesetzter Richtung wirkend an der mindestens einen Auflagefläche an der Unterseite des Flansches anliegt, wenn die Last an der Haltevorrichtung frei hängt.In the context of the method is further provided that the acted upon by the at least one hold-down force assumes the amount acting as a pulling force in the opposite direction acting on the at least one bearing surface on the underside of the flange when the load on the fixture hangs freely.

Gleichsam kann vorgesehen sein, dass sich die durch den mindestens einen Niederhalter beaufschlagte Kraft dem Betrag anpasst, welcher als dynamische Zugkraft in entgegengesetzter Richtung wirkend an der mindestens einen Auflagefläche an der Unterseite des Flansches anliegt, wenn die Last an der Haltevorrichtung hängend schwingt.Similarly, it can be provided that the acted upon by the at least one hold down force adapts to the amount acting as a dynamic tensile force in the opposite direction acting on the at least one bearing surface on the underside of the flange when the load on the holding device swinging hanging.

Dies gewährt eine Anpassung der mittels des Niederhalters wirkenden Kräfte je nach Beanspruchung und vermindert somit die Gefahr einer Beschädigung des Flansches durch Aufbiegen.This allows an adaptation of the forces acting by means of the hold-down forces depending on the load and thus reduces the risk of damage to the flange by bending.

Durch die erfindungsgemäße Lösung wird eine Haltevorrichtung bereitgestellt, bei der die Gefahr eines Aufbiegens eines Flansches einer zu transportierenden Last in Bezug auf den Stand der Technik weitergehend vermindert beziehungsweise optimiert wird. In einer bevorzugten Ausgestaltung ist zudem eine Anpassung an unterschiedliche Lasten möglich, so an unterschiedliche Wanddicken von Rohren, indem der Niederhalter verschiebbar ist. Daneben besteht ein verbesserter Schutz des Flansches bei einem Aufrichten der Last aus einer horizontalen in die senkrechte Lage.By the solution according to the invention, a holding device is provided, in which the risk of bending of a flange of a load to be transported with respect to the prior art is further reduced or optimized.
