Definitions
- the invention relates to a holding device for loads with a flange, the holding device having at least two bearing surfaces which can be arranged under the flange on an underside of the flange.
- Such devices have been known for several years, so from DE 10 2011 011 603 A1 , the EP 2 402 278 A1 , the EP 2 661 408 as well as the WO 2013 091632 A1 .
- the load in the area of the flange and the area adjoining the flange, i.e. the lateral surface is subjected to severe stress. If, for example, tubular, elongated loads that have a flange at least on one end face are transported, deformations in the above-described area can occur in connection with the transport process.
- a solution with at least one hold-down device for a flange of a load is already known, which can also be provided on the flange of adjacent lateral surfaces.
- a hold-down device is constructed in a relatively complex manner and it exerts a force on the flange and/or the adjacent lateral surface that is independent of the transport process.
- the known devices have the problem of simply adapting them to different diameters of elongated tubular loads to be lifted.
- the object of the invention is therefore to provide a holding device for transporting corresponding loads with a flange, for example tubular segments of a wind turbine, which is optimized compared to the known devices.
- the holding device for a load with a flange arranged at at least one end which as a rule—but not required according to the invention—is configured circumferentially, has the following features.
- the holding device can be arranged on a crane-like hoist, for example on its upper side. On its underside, for example, it has at least four inner clamping elements which can be arranged and adjusted in pairs on an inner surface of the flange and have bearing surfaces for the flange of the load, thus at least two pairs of inner clamping elements.
- one pair of the at least two pairs of inner clamping elements is arranged on the holding device so as to be linearly displaceable relative to one another on an imaginary axis.
- the at least two pairs of the inner clamping elements are arranged on the holding device so that they are shifted parallel to one another.
- the imaginary axes on which the pairs of inner clamping elements are located are shifted in parallel.
- each inner clamping element of the at least two pairs is slidably arranged on the holding device.
- This is advantageous because it enables adaptability to different cross-sections and weights of the load, which is WO 2013 091632 A1 is not given. There, an adjustment is only provided on one side and it cannot be adapted to different Weights and sizes are given because it is not possible to balance the suspended load in this way. If there is only one pair of clamping elements, it is usually not possible to accommodate particularly heavy loads. This requires several pairs of clamping elements.
- the holding device can be arranged in a known manner on a crane-like hoist, for example on the top, preferably via a pivoting device, whereby the holding device can be pivoted and locked from a horizontal position to a vertical position in a controllable manner in order to pick up a horizontal load with a flange and erect it and then to be able to transport it in a vertical position.
- an outer clamping element is arranged on the holding device corresponding to each of the inner clamping elements of the at least two pairs.
- the outer clamping elements also form at least two pairs.
- Each of the outer clamping elements of the at least two pairs is itself slidably arranged on the holding device so that it can be adapted to the scope of the load to be transported and a change in position can take place together with the inner clamping elements.
- the outer clamping elements each have guides, optionally with rollers. These serve to improve the positioning of the holding device on the load in order to reduce damage to the load and/or the holding device.
- At least one hold-down device is provided on the holding device, corresponding to each bearing surface of the respective inner clamping elements and thus to each clamping element.
- the respective hold-down device can then apply a force to an upper side of the flange of the load when the holding device is functionally arranged on the load during the transport process, depending on the design of the hold-down device also a force that is independent of a transport process, in order to further reduce deformation of the flange .
- the holding device contains at least two beam traverses which are arranged parallel to one another and are detachably connected to one another, for example via a frame.
- Each inner clamping element of the at least two pairs is arranged on the at least two beam traverses so that it can be displaced on the load side, for example on the underside thereof.
- Beam trusses within the meaning of the invention can also be other devices, such as rails, which can accommodate the inner or the inner and outer clamping elements in a linearly displaceable manner.
- the beam traverses offer great variability and can be adapted to the load to be lifted as required. Beam trusses can be omitted or added. Thus, a kind of changeable, especially expandable modular system Holding device made available, which was not previously known.
- each outer clamping element of the at least two pairs is arranged displaceably on the load side on the at least two beam traverses and through the respective outer clamping element and the respective corresponding inner clamping element a form fit to the the flange adjoining shell area of the load can be produced.
- the inner parallel-displaced clamping elements are designed to be connectable to one another and the outer parallel-displaced clamping elements are also designed to be connectable to one another.
- central control of the inner and outer clamping elements can take place across the board.
- the disclosed holding device is thus optimized compared to known devices. It is adaptable for different sizes of cross-sectional areas of loads and weights of loads. Furthermore, bending up of a flange of a load to be transported can be reduced in a more optimized manner.
- a holding device 1 which is intended for receiving a load 6 in the form of tower segments for wind turbines, the tower segments having a flange 5 at one end.
- the holding device 1 can attack this flange 5 as intended.
- the holding device 1 can be arranged on a crane-like hoist on its upper side and has a corresponding holder for this purpose.
- the holding device 1 On its underside 2 the holding device 1 has six inner clamping elements 3 which can be arranged and adjusted in pairs on an inner surface of the flange 5 and have bearing surfaces 4 for the flange 5 of the load 6 . These are six pairs of inner clamping elements 3.
- One pair of the six pairs of inner clamping elements 3 is arranged on a beam traverse 11 in a linearly displaceable manner relative to one another on the holding device.
- the beam traverses 11 are mutually parallel shifted side by side and so are also the six pairs of inner clamping elements 3 parallel shifted to each other on the Holding device 1 arranged.
- Each inner clamping element 3 of the six pairs is also arranged on the holding device 1 in a displaceable manner.
- outer clamping elements 9 are used and each outer clamping element 9 is arranged on the six beam traverses so that it can be displaced on the load side, corresponding to the six pairs of inner clamping elements 3 . So there are also six pairs of outer clamping elements 9 in the embodiment.
- the inner clamping elements 3 meaning the pairs that are shifted in parallel and not the pairs that are opposite one another on an axis, are connected to one another in the exemplary embodiment by means of bridges.
- This also applies to the outer clamping elements 9 .
- the outer clamping elements 9 are therefore relatively difficult to see. They are covered by a bridge designed with a radius, a kind of stirrup.
- the bridges are removable and so the inner clamping elements 3 and the outer clamping elements 9 can be adapted to the load 6 to be transported as required. They are therefore also arranged to be displaceable on the respective beam traverse 11 .
- two outer clamping elements 9 each have guides 10 with rollers. As already explained, these serve to improve the positioning of the holding device on the load and reduce damage to the load and/or the holding device.
- This provides improved containment of the risk of deformation of the flange 5 and thus the load 6 during the entire transport process, starting with the movement of the load 5 from a horizontal position to a vertical position and further transport in a vertical position when the holding device is on a crane hook or another suitable device of a crane is arranged.

Description
Die Erfindung bezieht sich auf eine Haltevorrichtung für Lasten mit einem Flansch, wobei die Haltevorrichtung mindestens zwei unter dem Flansch an einer Unterseite des Flansches anordenbare Auflageflächen aufweist. Derartige Vorrichtungen sind seit mehreren Jahren bekannt, so aus der
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 und insbesondere der Mantelfläche.It should be noted that such elongated tubular loads are usually stored horizontally on the ground. If a known device is attached to a flange, the above-described area of the flange and in particular the lateral surface is subjected to considerable stresses even when the tubes are erected in a vertical position.
Aus der
Darüber hinaus besteht bei den bekannten Vorrichtungen das Problem, diese einfach an unterschiedliche Durchmesser von zu hebenden röhrenförmig lang gestreckten Lasten anzupassen.In addition, the known devices have the problem of simply adapting them to different diameters of elongated tubular loads to be lifted.
Aufgabe der Erfindung ist es daher, eine Haltevorrichtung für einen Transport entsprechender Lasten mit einem Flansch, so beispielsweise röhrenförmige Segmente einer Windkraftanlage, bereitzustellen, welche gegenüber den bekannten Vorrichtungen optimiert ist.The object of the invention is therefore to provide a holding device for transporting corresponding loads with a flange, for example tubular segments of a wind turbine, which is optimized compared to the known devices.
Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Hauptanspruchs 1 gelöst, wobei die Unteransprüche weitere erfindungsgemäße Ausgestaltungsvarianten dieser Lösungen beinhalten.This object is achieved according to the invention by the features of main claim 1, with the subclaims containing further design variants of these solutions according to the invention.
Danach weist die Haltevorrichtung für eine Last mit einem an mindestens einem Ende angeordneten Flansch, der in Regel - aber nicht erfindungsnotwendig - umlaufend ausgestaltet ist, folgende Merkmale auf.According to this, the holding device for a load with a flange arranged at at least one end, which as a rule—but not required according to the invention—is configured circumferentially, has the following features.
Die Haltevorrichtung ist an ein kranartiges Hebezeug, zum Beispiel an seiner Oberseite, anordenbar. Sie weist, zum Beispiel an ihrer Unterseite, mindestens vier paarweise an einer Innenfläche des Flansches anordenbare und verstellbare innere Klemmelemente mit Auflageflächen für den Flansch der Last auf, somit mindestens zwei Paar innere Klemmelemente. Jeweils ein Paar der mindestens zwei Paar inneren Klemmelemente ist auf einer gedachten Achse linear verschiebbar zueinander an der Haltevorrichtung angeordnet. Ferner sind die mindestens zwei Paare der inneren Klemmelemente zueinander parallel verschoben an der Haltevorrichtung angeordnet. Die gedachten Achsen, auf denen die paarweise angeordneten inneren Klemmelemente gelegen sind, sind dabei parallel verschoben.The holding device can be arranged on a crane-like hoist, for example on its upper side. On its underside, for example, it has at least four inner clamping elements which can be arranged and adjusted in pairs on an inner surface of the flange and have bearing surfaces for the flange of the load, thus at least two pairs of inner clamping elements. In each case one pair of the at least two pairs of inner clamping elements is arranged on the holding device so as to be linearly displaceable relative to one another on an imaginary axis. Furthermore, the at least two pairs of the inner clamping elements are arranged on the holding device so that they are shifted parallel to one another. The imaginary axes on which the pairs of inner clamping elements are located are shifted in parallel.
Vorzugsweise ist jedes innere Klemmelement der mindestens zwei Paare verschiebbar an der Haltevorrichtung angeordnet. Dies ist vorteilhaft, weil so eine Anpassbarkeit an verschiedene Querschnitte und Gewichte der Last ermöglicht wird, was bei der
Die Haltevorrichtung ist in bekannter Weise an ein kranartiges Hebezeug, beispielhaft an der Oberseite, vorzugsweise über eine Schwenkvorrichtung, anordenbar, wodurch die Haltevorrichtung von einer waagerechten Lage in eine senkrechte Lage steuerbar verschwenkbar und arretierbar ist, um eine waagerecht lagernde Last mit Flansch aufzunehmen, aufzurichten und sodann in senkrechter Lage transportieren zu können.The holding device can be arranged in a known manner on a crane-like hoist, for example on the top, preferably via a pivoting device, whereby the holding device can be pivoted and locked from a horizontal position to a vertical position in a controllable manner in order to pick up a horizontal load with a flange and erect it and then to be able to transport it in a vertical position.
Neben den inneren Klemmelementen ist an der Haltevorrichtung korrespondierend zu jeden der inneren Klemmelemente der mindestens zwei Paare jeweils ein äußeres Klemmelement angeordnet. So bilden die äußeren Klemmelemente ebenfalls mindestens zwei Paare. Durch das jeweilige äußere Klemmelement und das jeweils korrespondierende innere Klemmelement ist bei funktionsgemäßer Anordnung der Haltevorrichtung an der zu transportierenden Last ein Formschluss an den dem Flansch sich anschließenden Mantelbereich der Last herstellbar. So ist der Mantelbereich mittels der inneren und äußeren Klemmelemente mit einer unabhängig von dem Transportvorgang wirkenden Kraft beaufschlagbar, wenn die inneren Klemmelemente und die äußeren Klemmelemente relativ zueinander auf der gedachten Achse verschoben und sodann arretiert werden, um so den Formschluss mit dem Flansch der Last sicherzustellen. Bei einem Aufrichten der Last aus der Waagerechten in die Senkrechte (Transportvorgang) ist die Gefahr der Verformung im zum Flansch sich anschließenden Mantelbereich dadurch reduziert.In addition to the inner clamping elements, an outer clamping element is arranged on the holding device corresponding to each of the inner clamping elements of the at least two pairs. The outer clamping elements also form at least two pairs. With a functional arrangement of the holding device on the load to be transported, the respective outer clamping element and the respective corresponding inner clamping element can be used to produce a form fit on the casing area of the load adjoining the flange. A force acting independently of the transport process can be applied to the casing area by means of the inner and outer clamping elements if the inner clamping elements and the outer clamping elements are displaced relative to one another on the imaginary axis and then locked in order to ensure the form fit with the flange of the load . When the load is raised from the horizontal to the vertical (transport process), the risk of deformation in the shell area adjoining the flange is reduced.
Jedes der äußeren Klemmelemente der mindestens zwei Paare ist selbst verschiebbar an der Haltevorrichtung angeordnet, sodass die Anpassbarkeit an den Umfang der zu transportierenden Last gewährt ist und eine Lageveränderung zusammen mit den inneren Klemmelementen erfolgen kann.Each of the outer clamping elements of the at least two pairs is itself slidably arranged on the holding device so that it can be adapted to the scope of the load to be transported and a change in position can take place together with the inner clamping elements.
Auch kann vorgesehen sein, dass die äußeren Klemmelemente jeweils Führungen, fakultativ mit Rollen, aufweisen. Diese dienen zur Verbesserung der Positionierung der Haltevorrichtung an der Last, um Beschädigungen der Last und/oder der Haltevorrichtung zu reduzieren.It can also be provided that the outer clamping elements each have guides, optionally with rollers. These serve to improve the positioning of the holding device on the load in order to reduce damage to the load and/or the holding device.
Zusätzlich zu den auf den Flansch der Last wirkenden inneren und äußeren Klemmelementen kann vorgesehen sein, dass an der Haltevorrichtung mindestens ein Niederhalter, korrespondierend je Auflagefläche der jeweiligen inneren Klemmelemente und somit je Klemmelement vorgesehen ist. Durch den jeweiligen Niederhalter ist sodann eine Oberseite des Flansches der Last bei funktionsgemäßer Anordnung der Haltevorrichtung an der Last während des Transportvorgangs mit einer Kraft, je nach Ausgestaltung der Niederhalter auch einer von einem Transportvorgang unabhängigen Kraft, beaufschlagbar, um eine Verformung des Flansches weiter zu reduzieren.In addition to the inner and outer clamping elements acting on the flange of the load, it can be provided that at least one hold-down device is provided on the holding device, corresponding to each bearing surface of the respective inner clamping elements and thus to each clamping element. The respective hold-down device can then apply a force to an upper side of the flange of the load when the holding device is functionally arranged on the load during the transport process, depending on the design of the hold-down device also a force that is independent of a transport process, in order to further reduce deformation of the flange .
In einer weiteren Ausgestaltung der Erfindung kann vorgesehen sein, dass die Haltevorrichtung mindestens zwei Balkentraversen enthält, die parallel zueinander angeordnet und miteinander lösbar verbunden sind, so beispielhaft über ein Gestell. Jedes innere Klemmelement der mindestens zwei Paare ist dabei lastseitig verschiebbar an den mindestens zwei Balkentraversen angeordnet, so beispielhaft an deren Unterseite. Balkentraversen im Sinne der Erfindung können auch andere Vorrichtungen sein, wie etwa Schienen, welche die inneren oder die inneren und äußeren Klemmelemente linear verschiebbar aufnehmen können.In a further embodiment of the invention it can be provided that the holding device contains at least two beam traverses which are arranged parallel to one another and are detachably connected to one another, for example via a frame. Each inner clamping element of the at least two pairs is arranged on the at least two beam traverses so that it can be displaced on the load side, for example on the underside thereof. Beam trusses within the meaning of the invention can also be other devices, such as rails, which can accommodate the inner or the inner and outer clamping elements in a linearly displaceable manner.
Die Balkentraversen bieten eine große Variabilität und können je nach Bedarf an die zu hebende Last angepasst werden. Es können Balkentraversen entfallen oder hinzukommen. Somit wird eine Art veränderbarer, insbesondere erweiterbarer Baukasten der Haltevorrichtung zur Verfügung gestellt, was bisher nicht bekannt war.The beam traverses offer great variability and can be adapted to the load to be lifted as required. Beam trusses can be omitted or added. Thus, a kind of changeable, especially expandable modular system Holding device made available, which was not previously known.
Ferner kann auch bei dieser Ausgestaltung der Erfindung vorgesehen sein, dass äußere Klemmelemente zum Einsatz kommen und jedes äußere Klemmelement der mindestens zwei Paare lastseitig verschiebbar an den mindestens zwei Balkentraversen angeordnet ist und durch das jeweilige äußere Klemmelement und das jeweils korrespondierende innere Klemmelement ein Formschluss an den dem Flansch sich anschließenden Mantelbereich der Last herstellbar ist. Dies gewährt, wie bei allen anderen gleichartigen Konstruktionen der Erfindung, eine verbesserte Eindämmung der Gefahr einer Verformung während des gesamten Transportvorgangs, beginnend von der Bewegung aus einer horizontalen Lage der Last in eine vertikale Lage und weiteren Transport in einer vertikalen Lage, wenn die Haltevorrichtung an einem Kranhaken eines Krans angeordnet ist.Furthermore, in this embodiment of the invention, it can also be provided that outer clamping elements are used and each outer clamping element of the at least two pairs is arranged displaceably on the load side on the at least two beam traverses and through the respective outer clamping element and the respective corresponding inner clamping element a form fit to the the flange adjoining shell area of the load can be produced. This, as with all other similar constructions of the invention, affords improved containment of the risk of deformation throughout the transport process, beginning with movement of the load from a horizontal position to a vertical position and further transport in a vertical position when the holding device is on a crane hook of a crane is arranged.
Auch hier können wiederum die vorab beschriebenen Niederhalter zum Einsatz kommen.Here again, the hold-down devices described above can be used.
Des Weiteren kann in einer Ausgestaltung der Erfindung vorgesehen sein, dass die inneren parallel verschobenen Klemmelemente miteinander verbindbar gestaltet sind und die äußeren parallel verschobenen Klemmelemente ebenfalls miteinander verbindbar gestaltet sind. So kann beispielhaft eine zentrale Steuerung der inneren und äußeren Klemmelemente übergreifend erfolgen.Furthermore, in one embodiment of the invention, it can be provided that the inner parallel-displaced clamping elements are designed to be connectable to one another and the outer parallel-displaced clamping elements are also designed to be connectable to one another. For example, central control of the inner and outer clamping elements can take place across the board.
Die offenbarte Haltevorrichtung ist somit gegenüber bekannten Vorrichtungen optimiert. Sie ist für verschiedene Größen von Querschnittsflächen der Lasten und Gewichte der Lasten anpassbar. Ferner kann bei dieser ein Aufbiegen eines Flansches einer zu transportierenden Last auf optimiertere Weise vermindert werden.The disclosed holding device is thus optimized compared to known devices. It is adaptable for different sizes of cross-sectional areas of loads and weights of loads. Furthermore, bending up of a flange of a load to be transported can be reduced in a more optimized manner.
