Description

Die Erfindung betrifft einen C-Greifer zur Anordnung an eine Traverse oder an ein Tragmittel und eine Traverse mit mindestens einem solchen C-Greifer zum Transport von Hebegütern, wobei der C-Greifers in seiner Höhe verstellbar ist.The invention relates to a C-gripper for arrangement on a traverse or on a suspension element and a traverse with at least one such C-gripper for the transport of goods, wherein the C-gripper is adjustable in height.

C-Greifer sind seit vielen Jahren bekannt, so u.a. aus der EP 2873641 A1 . Bei dem dort offenbarten C-Greifer handelt es sich um einen mit einem starren Aufbau. Dies hatte in der Vergangenheit zu Nachteilen beim Transport geführt. Derartige Greifer sind nämlich in der Regel nicht in einen üblichen Container verladbar, da es gerade bei einem Einsatz auf Schiffen, so beispielhaft bei der Montage von Off-Shore-Windkraftanlagen vorteilhaft ist, wenn dort ein solcher Greifer bzw. eine Traverse mit mindestens einem solchen Greifer eingesetzt werden soll. Bei herkömmlichen starren C-Greifern bzw. C-Elementen besteht darüber hinaus das Problem, dass die größten Belastungen und damit das höchste Schädigungspotenzial in Eckbereichen einer vertikalen Strebe, auch genannt Rücken, auftreten.C-grippers have been known for many years, including the EP 2873641 A1 , The disclosed there C-gripper is one with a rigid structure. This had led to disadvantages in the past in transport. Such grippers are usually not loadable into a conventional container, since it is advantageous, especially when used on ships, so for example in the assembly of off-shore wind turbines, if there such a gripper or a traverse with at least one such Gripper should be used. In the case of conventional rigid C-grippers or C-elements, there is also the problem that the greatest loads and thus the highest damage potential occur in corner areas of a vertical strut, also called a back.

Die Aufgabe der Erfindung besteht demgemäß darin, einen C-Greifer bzw. eine Traverse mit mindestens einem solchen C-Greifer bereitzustellen, die in ihrem Raumvolumen reduzierbar ist bzw. deren üblicherweise starre Form, so ihre Höhe, veränderbar ist. Eine weitere Aufgabe besteht darin, das Schädigungspotenzial in den Eckbereichen der vertikalen Strebe zu reduzieren.The object of the invention is accordingly to provide a C-gripper or a cross-beam with at least one such C-gripper, which is reducible in its volume or whose usually rigid shape, so its height is variable. Another task is to reduce the potential for damage in the corner areas of the vertical strut.

Die Aufgabe wird erfindungsgemäß durch einen C-Greifer gemäß dem Hauptanspruch 1 und einer Traverse mit mindestens einem solchen C-Greifer gemäß dem unabhängigen Anspruch 9 gelöst. Die abhängigen Unteransprüche beinhalten nähere Ausgestaltungen der Erfindung.The object is achieved by a C-gripper according to the main claim 1 and a traverse with at least one such C-gripper according to independent claim 9 . The dependent subclaims contain further embodiments of the invention.

Danach besteht ein C-Greifer zur Handhabe eines Hebegutes, der zur Anordnung an eine Traverse oder an ein Tragmittel, so beispielhaft einen Kranhaken, bestimmt ist, aus einer Oberstrebe, einer Vertikalstrebe und einer Auflagestrebe, welche einen so genannten Hakengrund bildet, auf welche das Hebegut auflegbar ist, wobei Auflegen im Sinne der Erfindung neben dem Auflegen als solches auch eine hängende Lagerung des Hebeguts an der Auflagestrebe sein kann. Das Hebegut wird insofern auf oder an der Auflagestrebe angeordnet. Die Oberstrebe und die Vertikalstrebe sind, wie bei herkömmlichen Konstruktionen, miteinander starr verbunden und im Wesentlichen rechtwinklig zueinander angeordnet, wobei andere Winkel ebenfalls im Rahmen der Erfindung liegen. Die Auflagestrebe ist aber nicht starr, sondern vielmehr drehbar gelagert mit der Vertikalstrebe verbunden und zwar derart, dass ein lichtes Maß (h) eines Mauls des C-Greifers veränderbar, so vergrößerbar oder auch verkleinerbar ist. Des Weiteren ist die die Vertikalstrebe teleskopierbar. Sie ist so als eine Teleskopstrebe ausgebildet.Thereafter, there is a C-gripper for handling a lifting, which is intended to be arranged on a crossmember or to a support means, such as a crane hook, from a top strut, a vertical strut and a support strut, which forms a so-called hook base on which Lifting material can be placed, wherein placing in the sense of the invention in addition to the laying as such can also be a hanging storage of the lifting material on the support strut. The lifted material is arranged on or on the support strut. The upper strut and the vertical strut, as in conventional constructions, are rigidly connected to each other and arranged substantially perpendicular to each other, wherein other angles are also within the scope of the invention. The support strut is not rigidly but rather rotatably mounted connected to the vertical strut and in such a way that a light measure (h) of a mouth of the C-gripper changeable, so enlargeable or reducible. Furthermore, the vertical strut is telescopic. It is designed as a telescopic strut.

Die Arretierung der teleskopierbaren Vertikalstrebe erfolgt mittels einer bekannten Haltevorrichtung, so beispielhaft durch mindestens einen Bolzen je Segment oder ähnliche Haltevorrichtungen. Es kommen alle Vorrichtungen in Betracht, welche eine funktionssichere Arretierung gewähren.The locking of the telescopic vertical strut by means of a known holding device, so for example by at least one bolt per segment or similar holding devices. There are all devices into consideration, which grant a functionally reliable locking.

Erfindungsgemäß erfolgt die Arretierung der drehbar gelagerten Auflagestrebe, so die Einstellung des lichten Maßes (h) des Mauls und damit auch die Regulierung der Drehbewegung, mittels mindestens eines biegeschlaffen Lastmittels, welches relativ zur Vertikalstrebe in Richtung des Mauls des C-Greifers verschoben an der Oberstrebe und der Auflagestrebe funktionssicher angeordnet ist. Vorzugsweise ist das mindestens eine biegeschlaffe Lastmittel parallel verschoben zur Vertikalstrebe in Richtung Maul des C-Greifers an der Oberstrebe und der Auflagestrebe funktionssicher angeordnet. Das mindestens eine biegeschlaffe Lastmittel ist beispielhaft eine Schlinge mit drehbar gelagerten Aufnahmen, so beispielhaft Rollen, an der Oberstrebe und der Auflagestrebe und in seiner Länge veränderbar, so beispielhaft mittels Winden, Winschen oder anderer bekannter geeigneter Vorrichtungen.According to the locking of the rotatably mounted support strut, so the adjustment of the clear dimension (h) of the mouth and thus the regulation of the rotational movement, by means of at least one limp load medium, which is displaced relative to the vertical strut in the direction of the mouth of the C-gripper on the upper strut and the support strut is arranged functionally reliable. Preferably, the at least one pliable load means is parallel to the vertical strut in the direction of the mouth of the C-gripper on the upper strut and the support strut arranged functionally reliable. The at least one flexible load means is exemplified by a loop with rotatably mounted receptacles, such as rollers, on the upper strut and the support strut and in its length changeable, so for example by means of winches, winches or other known suitable devices.

Die Verschiebung erfolgt in dem Umfang, wie es konstruktiv erforderlich ist. Sie kann variabel entsprechend der Konstruktion und der Art des Hebeguts erfolgen.The shift occurs to the extent that is structurally required. It can be variable according to the design and type of load.

Vorteilhafterweise ist die drehbar gelagerte Auflagestrebe an einem eigenen freien Ende mit einem freien Ende der Vertikalstrebe verbunden. Die Einstellung des lichten Maßes (h) des Mauls erfolgt vorteilhafterweise derart, dass die Auflagestrebe in einem rechten Winkel zur Teleskopstrebe angeordnet ist. Es sind jedoch auch andere Winkelmaße im Bereich der Erfindung gelegen, soweit die Funktionsfähigkeit des C-Greifers nicht beeinträchtigt ist.Advantageously, the rotatably mounted support strut is connected at its own free end to a free end of the vertical strut. The adjustment of the clearance (h) of the mouth is advantageously carried out such that the support strut is arranged at a right angle to the telescopic strut. However, other angular dimensions are also within the scope of the invention, as far as the functionality of the C-gripper is not impaired.

Zu beachten ist ergänzend, dass sowohl die Oberstrebe, die Vertikalstrebe, als auch die Auflagestrebe im Sinne der Erfindung nicht nur als eine einzige Strebe zu verstehen sind, sondern auch verschiedene Streben oder sonstige konstruktive Anordnungen darstellen können.It should be noted in addition that both the upper strut, the vertical strut, as well as the support strut in the context of the invention are not only to be understood as a single strut, but may also represent different struts or other constructive arrangements.

Diese bilden jedoch bei der Gesamtbetrachtung der Vorrichtung jeweils eine Baugruppe, die entsprechend als Oberstrebe, Vertikalstrebe oder Auflagestrebe definiert werden kann.However, these form in the overall consideration of the device each have an assembly that can be defined as a top strut, vertical strut or support strut accordingly.

Die erfindungsgemäße Vorrichtung ist somit hinsichtlich der Höhe des C-Greifers veränderbar, sodass ein optimierter Transport möglich ist. Darüber hinaus nimmt die teleskopierbare Vertikalstrebe in Arretierstellung im Einsatz mit dem Hebegut lediglich die Druckkräfte auf, wobei die Zugkräfte von dem mindestens einen biegeschlaffen Lastmittel aufgenommen werden. Diese Konstruktion ermöglicht, die Vertikalstrebe hinsichtlich ihrer Mächtigkeit zu reduzieren und somit Gewicht einzusparen. Darüber hinaus werden die Eckbereiche der Vertikalstrebe durch die erfindungsgemäße Konstruktion bei dem Einsatz des C-Greifers weniger stark belastet, sodass gleichsam das Schädigungspotenzial dieser Bereiche reduziert ist.The device according to the invention is thus variable with respect to the height of the C-gripper, so that an optimized transport is possible. In addition, the telescoping vertical strut in locking position in use with the lifting gear only on the compressive forces, wherein the tensile forces are absorbed by the at least one pliable load means. This construction makes it possible to reduce the vertical strut in terms of their thickness and thus save weight. In addition, the corner regions of the vertical strut are less heavily loaded by the construction according to the invention when using the C-gripper, so that as it were the damage potential of these areas is reduced.

In weiterer Ausgestaltung weist die Auflagestrebe mehrere höhenverstellbare Auflagesegmente zur Anpassung an die äußere Geometrie des Hebegutes, so eines Rotorblattes oder eines sonstigen Bauteils einer Windkraftanlage auf, welche in das Maul des C-Greifers hineinragen.In a further embodiment, the support strut has a plurality of height-adjustable support segments for adaptation to the outer geometry of the lifting material, such as a rotor blade or other component of a wind turbine, which project into the mouth of the C-gripper.

Die Oberstrebe kann weiter eine bekannte, relativ zum Auflageelement verschiebbare und in das Maul des C-Greifers weisende Klemmvorrichtung aufweisen, um das Hebegut arretieren zu können. Die Klemmvorrichtung selbst ist versetzt zur Vertikalstrebe in Richtung des Mauls und zu dem mindestens einen biegeschlaffen Lastmittel an der Oberstrebe angeordnet und in Richtung Auflagestrebe verschiebbar, sodass in Arretierstellung auf das Hebegut eine Kraft ausgeübt werden kann, die ein Verrutschen desselben verhindert bzw. minimiert.The upper strut may further comprise a known, relative to the support element displaceable and pointing into the mouth of the C-gripper clamping device to lock the load can. The clamping device itself is offset from the vertical strut in the direction of the mouth and the at least one pliable load means on the upper strut and displaceable in the direction of the support strut, so that in the locked position on the lifting a force can be exerted that prevents it from slipping or minimized.

Im Einsatz in der Arretierstellung wird sodann auch das mindestens eine biegeschlaffe Lastmittel gespannt, weil dieses, wie bereits dargelegt, die auf den C-Greifer, so die Auflagestrebe und die Vertikalstrebe, wirkenden Zugkräfte aufnimmt. Die Spannung des mindestens einen biegeschlaffen Lastmittels ist jedoch gleichsam dann gegeben, wenn lediglich das Hebegut mit seinem Eigengewicht auf oder an der Auflagestrebe angeordnet ist und somit eine Spannung des mindestens einen biegeschlaffen Lastmittels aufgrund des Eigengewichts des Hebeguts hervorgerufen wird.In use in the locking position then the at least one pliable load means is then stretched, because this, as already stated, on the C-gripper, so the support strut and the vertical strut, acting tensile forces. However, the tension of the at least one limp load means is given as it were when only the load is arranged with its own weight on or on the support strut and thus a tension of the at least one limp load means due to the dead weight of the load is caused.

In einem zusammengeschobenen Zustand des C-Greifers kann zudem das mindestens eine biegeschlaffe Lastmittel abgenommen und verstaut werden. Die Arretierung der Auflagetraverse kann dann mittels einer starren Strebe erfolgen.In a collapsed state of the C-gripper also the at least one pliable load means can be removed and stowed. The locking of the support traverse can then be done by means of a rigid strut.

Ebenfalls betrifft die Erfindung eine Traverse, so beispielhaft eine Balkentraverse, zur Handhabe eines Hebegutes, wobei die Traverse mindestens einen vorbeschriebenen C-Greifer aufweist. Die Traverse ist ebenfalls in bekannter Art wie der C-Greifer selbst an ein oder mehrere Tragmittel eines kranartigen Hebezeugs anordenbar. Vorzugsweise weist die Traverse zwei C-Greifer an ihren freien Enden auf, welche abnehmbar sind, um ein lang gestrecktes Hebegut, so ein Rotorblatt einer Windkraftanlage, transportieren zu können. Ein Transport lang gestreckter Hebegüter ist gleichsam bei einem Einsatz von mindestens zwei C-Greifern möglich.Also, the invention relates to a traverse, so for example a beam traverse, for handling a lifting material, wherein the traverse has at least one prescribed C-gripper. The traverse is also in a known manner as the C-gripper itself to one or more suspension means of a crane-like hoist can be arranged. Preferably, the cross member has two C-grippers at their free ends, which are removable in order to transport an elongated lifting material, such as a rotor blade of a wind turbine can. A transport of elongated goods is possible if at least two C-grippers are used.

Eine Abnehmbarkeit des mindestens einen C-Greifers ist dann vorteilhaft, wenn die Traverse mit den erfindungsgemäßen C-Greifern demontiert in einen üblichen Container zu verbringen ist. In einem solchen Fall ist sie aus mindestens zwei zueinander drehbar gelagerten Segmenten zusammensetzt, die es erlauben, die Traverse zu falten und so ihre Länge zu verringern. Vorzugsweise sind die mindestens zwei Segmente an Schmalseiten jeweils miteinander drehbar gelagert verbunden.A removability of the at least one C-gripper is advantageous if the traverse is disassembled with the inventive C-grippers to spend in a conventional container. In such a case, it is composed of at least two mutually rotatably mounted segments, which allow to fold the traverse and so reduce their length. Preferably, the at least two segments are connected to each other on narrow sides in each case rotatably mounted.

Die Faltbarkeit bzw. Demontagemöglichkeit von Traverse und dem mindestens einen C-Greifer, vorzugsweise zwei C-Greifern, einschließlich der Möglichkeit, die Höhe des mindestens einen C-Greifers zu verringern, erlaubt einen Transport der Vorrichtung, bei welcher das von ihr eingenommene Raumvolumen reduziert werden kann. Dies gewährleistet Transportvorteile, die sich nicht zuletzt auch in einer Reduzierung von Transportkosten niederschlagen.The foldability or disassembly possibility of traverse and the at least one C-gripper, preferably two C-grippers, including the ability to reduce the height of the at least one C-gripper, allows a transport of the device, in which reduces the space occupied by her volume can be. This ensures transport advantages, which are not least reflected in a reduction of transport costs.

In Fig. 1 ist ein C-Greifer 1 ersichtlich, welcher an eine Traverse 11 anordenbar ist. Der C-Greifer 1 besteht aus einer Oberstrebe 2, einer Vertikalstrebe 3 und einer Auflagestrebe 4. Die Auflagestrebe 4 besitzt mehrere Auflagesegmente 9 und bildet einen so genannten Hakengrund, auf welchen das Hebegut 14 auflegbar ist. Die Oberstrebe 2 und die Vertikalstrebe 3 sind wie bei herkömmlichen Konstruktionen miteinander starr verbunden und sind rechtwinklig zueinander angeordnet. Die Auflagestrebe 4 ist nicht starr, sondern drehbar gelagert mit der Vertikalstrebe 3 verbunden und zwar derart, dass ein lichtes Maß (h) eines Mauls 5 des C-Greifers 1 veränderbar, so vergrößerbar oder auch verkleinerbar ist. Die Auflagestrebe, 4 ist somit schwenkbar, was in Fig. 2 durch die Pfeile gekennzeichnet ist. Des Weiteren ist die Vertikalstrebe 3 teleskopierbar, im Ausführungsbeispiel zweifach teleskopierbar.In Fig. 1 is a C-gripper 1 can be seen, which can be arranged on a traverse 11 . The C-gripper 1 consists of a top strut 2 , a vertical strut 3 and a support strut 4. The support strut 4 has a plurality of support segments 9 and forms a so-called hook base on which the lifting material 14 can be placed. The upper strut 2 and the vertical strut 3 are rigidly connected together as in conventional constructions and are arranged at right angles to each other. The support strut 4 is not rigid, but rotatably mounted with the vertical strut 3 in such a way that a light measure (h) of a jaw 5 of the C-gripper 1 is changeable, so enlargeable or reducible. The support strut, 4 is thus pivotally, which in Fig. 2 indicated by the arrows. Furthermore, the vertical strut 3 is telescopic, in the exemplary embodiment can be telescoped twice.

Die Arretierung der teleskopierbaren Vertikalstrebe 3 erfolgt mittels zweier Haltevorrichtungen 6, so durch einen Bolzen je Segment. Erfindungsgemäß erfolgt die Arretierung der drehbar gelagerten Auflagestrebe, so die Einstellung des lichten Maßes (h) des Mauls, mittels eines biegeschlaffen Lastmittels 7, welches relativ zur Vertikalstrebe 3 in Richtung des Mauls 5 des C-Greifers 1 verschoben an der Oberstrebe 2 und der Auflagestrebe 4 mittels drehbarer Aufnahmen 8 angeschlagen ist. Das biegeschlaffe Lastmittel 7 ist dabei parallel verschoben zur Vertikalstrebe 3 in Richtung des Mauls 5 des C-Greifers 1 an der Oberstrebe 2 und der Auflagestrebe 4 angeschlagen. Das biegeschlaffe Lastmittel 7 ist im Ausführungsbeispiel eine Schlinge und an drehbar gelagerten Aufnahmen 8, nämlich Rollen, an der Oberstrebe 2 und der Auflagestrebe 4 angeordnet.The locking of the telescopic vertical strut 3 by means of two holding devices 6 , so by a bolt per segment. According to the locking of the rotatably mounted support strut, so the adjustment of the clear dimension (h) of the mouth, by means of a pliable load means 7 , which is displaced relative to the vertical strut 3 in the direction of the mouth 5 of the C-gripper 1 on the upper strut 2 and the support strut 4 is struck by means of rotatable shots 8 . The pliable load means 7 is parallel to the vertical strut 3 in the direction of the mouth 5 of the C-gripper 1 on the upper strut 2 and the support strut 4 posted. The pliable load means 7 is arranged in the embodiment a loop and rotatably mounted receptacles 8 , namely rollers, on the upper strut 2 and the support strut 4 .

Es ist in seiner Länge veränderbar. Auflagestrebe und Vertikalstrebe sind jedoch in Ausführungsbeispiel in einem rechten Winkel zueinander angeordnet.It is changeable in its length. However, support strut and vertical strut are arranged in an exemplary embodiment at a right angle to each other.

Die Oberstrebe 2 weist eine bekannte relativ zum Auflageelement 4 verschiebbare und in das Maul 5 des C-Greifers 1 weisende Klemmvorrichtung 10 auf, um das Hebegut 14 arretieren zu können. Die Klemmvorrichtung 10 selbst ist versetzt zur Vertikalstrebe 3 und zu dem biegeschlaffen Lastmittel 7 in Richtung Maul 5 an der Oberstrebe 2 angeordnet und in Richtung der Auflagestrebe 9 verschiebbar, sodass in Arretierstellung auf das Hebegut 14 eine Kraft ausgeübt werden kann, die ein Verrutschen desselben verhindert beziehungsweise minimiert. Im Einsatz in der Arretierstellung wird sodann ebenfalls das biegeschlaffe Lastmittel 7 gespannt. Es nimmt dann die auf den C-Greifer 1, so die Auflagestrebe 4 und die Vertikalstrebe 3, wirkenden Zugkräfte auf, Fig. 2 . Die Spannung des biegeschlaffen Lastmittels 7 ist jedoch gleichsam gegeben, wenn lediglich das Hebegut 14 mit seinem Eigengewicht auf der Auflagestrebe 4 aufliegt und somit eine Spannung des biegeschlaffen Lastmittels 7 aufgrund des Eigengewichts des Hebeguts 14 hervorgerufen wird, Fig. 1 . The upper strut 2 has a known relative to the support element 4 displaceable and in the mouth 5 of the C-gripper 1 facing clamping device 10 to lock the load 14 can. The clamping device 10 itself is offset from the vertical strut 3 and the slippery load means 7 in the direction of mouth 5 on the upper strut 2 and slidable in the direction of the support strut 9 so that in the locked position on the lifting 14 a force can be exercised, which prevents it from slipping or minimized. In use in the locking position then the pliable load means 7 is also stretched. It then absorbs the tensile forces acting on the C-gripper 1 , thus the support strut 4 and the vertical strut 3 , Fig. 2 , However, the tension of the slippery load means 7 is given as it were, if only the lifting material 14 rests with its own weight on the support strut 4 and thus a voltage of the pliable load means 7 is caused due to the dead weight of the lifting 14 Fig. 1 ,

In einem Volumen minimierten Zustand des C-Greifers 1 sind Elemente der Vertikalstrebe 3 zusammengeschoben. Zudem ist das biegeschlaffe Lastmittel 7 abgenommen. Die Arretierung der Auflagetraverse erfolgt dann mittels einer starren Strebe 15, Fig. 3 . In a volume minimized state of the C-gripper 1 elements of the vertical strut 3 are pushed together. In addition, the pliable load means 7 is removed. The locking of the support beam is then done by means of a rigid strut 15 , Fig. 3 ,

In Fig. 4 ist eine Traverse 11, bestehend aus drei Segmenten 12, abgebildet, die über Hebebänder an ein Tragmittel eines Krans zur Handhabe eines Rotorblattes einer Windkraftanlage angeordnet ist. Die Segmente sind zueinander an jeweiligen Schmalseiten 13 schwenkbar angeordnet. Die Traverse 11 weist an ihren freien Enden jeweils einen C-Greifer 1 auf.In Fig. 4 is a traverse 11 , consisting of three segments 12 , shown, which is arranged via lifting straps to a support means of a crane for the handle of a rotor blade of a wind turbine. The segments are arranged pivotably relative to one another on respective narrow sides 13 . The traverse 11 has at its free ends in each case a C-gripper 1 .

Diese sind abnehmbar, um die Traverse 11 mit den erfindungsgemäßen C-Greifern 1 in einen üblichen Container verstauen zu können. In einem solchen Fall ist die aus den drei zueinander drehbar gelagerten Segmenten 12 zusammengesetzte Traverse 11 faltbar. So ist eine Platz sparende Lagerung der Traverse gewährleistet. Die Traverse 11 mit ihren zwei C-Greifern 1 ist für den Transport von lang gestreckten Hebegütern, so etwa Turmsegmenten oder Rotorblättern von Windkraftanlagen geeignet.These are removable in order to stow the traverse 11 with the inventive C-grippers 1 in a conventional container can. In such a case, the cross member 11 composed of the three rotatably mounted segments 12 is foldable. This ensures a space-saving storage of the traverse. The traverse 11 with its two C-grippers 1 is suitable for the transport of elongated lifting goods, such as tower segments or rotor blades of wind turbines.
