Description
Die vorliegende Erfindung betrifft eine Klettereinrichtung für einen Turmdrehkran, mit einem entlang des Kranturms verfahrbaren Kletterrahmen zum Ein- und/oder Abklettern von Turmstücken, wobei eine Führung zum längsverfahrbaren Abstützen des Kletterrahmens gegenüber dem Kranturm vorgesehen ist.The present invention relates to a climbing device for a tower crane, with a movable along the crane tower climbing frame for climbing and / or climbing off tower pieces, with a guide for longitudinally movable supporting the climbing frame is provided opposite the crane tower.
Turmdrehkrane werden üblicherweise durch den Einbau zusätzlicher Turmstücke an die zunehmende Höhe des Bauwerks angepasst. Dieser Vorgang wird im Allgemeinen als Klettern bezeichnet. Um ein Turmstück einklettern zu können, wird üblicherweise der Kranoberteil, der einen Kranausleger umfassen kann, vom obersten Turmstück gelöst und von einem Kletterrahmen gehalten, der achsialverschieblich an dem Kranturm gelagert ist. Nach Lösen der Verbindung des Kranoberteils vom obersten Turmstück wird der genannte Kletterrahmen soweit nach oben gefahren, dass zwischen dem gelösten Kranoberteil und das oberste Turmstück ein weiteres Turmstück eingepasst werden kann, auf das dann der Kranoberteil abgesetzt oder nochmals ein weiteres Turmstück nach einem nochmaligen Aufklettern aufgesetzt werden kann.Tower cranes are usually adapted to the increasing height of the structure by installing additional tower sections. This process is commonly referred to as climbing. In order to climb a tower section, usually the crane top, which may comprise a crane boom, detached from the top tower piece and held by a climbing frame, which is mounted axially displaceable on the crane tower. After loosening the connection of the crane shell from the top tower section of said climbing frame is moved far enough that between the dissolved crane shell and the top tower piece another tower piece can be fitted, then dropped off the crane top or another tower section after a second climbing up can be.
Der genannte Kletterrahmen kann den Kranturm nach Art einer Schiebehülse außenseitig umgeben und eine seitliche Einführöffnung aufweisen, durch die hindurch ein weiteres Turmstück eingesetzt bzw. beim Abklettern auch wieder herausgenommen werden kann. Alternativ ist es auch bekannt, das Kranoberteil vorübergehend beim Auf- und Abklettern auf den Kletterrahmen seitlich versetzt zum Turm abzustützen, sodass der Turm an der Oberseite frei zugänglich ist, um dort Turmstücke aufzusetzen bzw. abnehmen zu können. Auch in diesem Fall ist der genannte Kletterrahmen an dem Kranturm bzw. dessen Turmstücken längsverschieblich gelagert.Said climbing frame can surround the crane tower on the outside in the manner of a sliding sleeve and have a lateral insertion opening through which another tower section can be inserted or taken out again when climbing. Alternatively, it is also known to support the crane top side temporarily when climbing and climbing on the climbing frame laterally offset to the tower, so that the tower is freely accessible at the top to put there tower pieces or to be able to remove. Also in this case, said climbing frame is mounted longitudinally displaceable on the crane tower or its tower sections.
Um das beim Auf- und Abklettern vorübergehend nur auf dem Kletterrahmen gelagerte Kranoberteil mitsamt Ausleger sicher abzustützen und entsprechende Kipp- und Biegemomente aufnehmen zu können, wird der Kletterahmen mittels einer Führung am Kranturm zwar längsverschiebbar, aber kippstabil abgestützt. Solche Kippmomente können einerseits durch Windlasten, andererseits bspw. aber auch durch das Aufnehmen und Ablassen von ein- und abzukletternden Turmstücken entstehen, die durch die Hubmittel am Kran selbst auf- und abgelassen werden können.In order to support the mounted during climbing and climbing temporarily only on the climbing frame crane top together with boom and record appropriate tilt and bending moments, the climbing frame by means of a guide on the crane tower, although longitudinally displaceable, but supported tilt stability. Such tilting moments can arise on the one hand by wind loads, on the other hand, for example. But also by receiving and releasing of climbing and abzukletternden tower pieces that can be opened and lowered by the lifting means on the crane itself.
Die längsverschiebliche Führung des Kletterrahmens am Kranturm kann dabei Querstützelemente bspw. in Form von Gleitblechen umfassen, die bspw. am Kletterrahmen angebracht sein und den Kranturm von verschiedenen Seiten her umgreifen können. Beispielsweise können Gleitbleche an den Längs- bzw. Eckstielen der üblicherweise als Fachwerkträger ausgebildeten Turmstücke angreifen, um den Kletterrahmen längsverschieblich, aber kippstabil am Kranturm zu führen. Anstelle solcher Gleitbleche können auch Führungsrollen am Kletterrahmen vorgesehen sein, die bspw. an den genannten Eckstielen der Turmstücke abrollen können.The longitudinally displaceable guidance of the climbing frame on the crane tower can in this case include transverse support elements, for example in the form of sliding plates, which, for example, can be attached to the climbing frame and can encompass the crane tower from different sides. For example, sliding plates can engage the longitudinal or corner posts of the tower sections, which are usually designed as truss girders, in order to guide the climbing frame longitudinally displaceable but tilt-stable on the crane tower. Instead of such sliding plates, guide rollers can also be provided on the climbing frame, which, for example, can roll on the said corner posts of the tower sections.
Eine Klettereinrichtung für Turmdrehkrane der genannten Art zeigt bspw. die Schrift
Bei bisherigen Klettereinrichtungen der genannten Art kommt es bislang zu relativ starkem Verschleiß entlang der Kontaktflächen der Turmstücke. Dies ist bspw. bei Kranen, die an Windanlagen eingesetzt werden, besonders gravierend, da solche Krane in kurzer Zeit auf- und abgeklettert werden müssen. Zudem kommt es bisweilen zu einem ruckhaften, unsaftem Verschieben des Kletterrahmens, wenn dieser aufgrund von sogenannten Slip-Stick-Effekten nicht ruckfrei angefahren bzw. stillgesetzt werden kann, oder sich an den Turmstücken, insbesondere deren Übergangsbereichen zu große Form- bzw. Maßtoleranzen ergeben, die zu Mikroverkippungen oder gar Klemmtendenzen des Kletterrahmens führen können. Solche ruckelnden Bewegungen des Kletterrahmens sind jedoch in hohem Maße unerwünscht, da der Kletterrahmen während seiner Verfahrbewegung den ganzen Kranoberteil einschließlich Ausleger trägt.In previous climbing devices of the type mentioned so far it comes to relatively heavy wear along the contact surfaces of the tower pieces. This is particularly serious, for example, in cranes that are used on wind turbines, since such cranes in a short time up and have to be climbed. It also comes sometimes a jerky, unsaftem moving the climbing frame, if it can not be approached or shut down due to so-called slip-stick effects without jerking, or arise at the tower pieces, in particular their transition areas to large dimensional tolerances that lead to Mikroverkippungen or even clamping tendencies of the climbing frame can lead. However, such jerky movements of the climbing frame are highly undesirable, since the climbing frame carries the entire crane top including boom during its movement.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine verbesserte Klettereinrichtung der eingangs genannten Art zu schaffen, die Nachteile des Standes der Technik vermeidet und Letzteren in vorteilhafter Weise weiterbildet. Insbesondere soll die Klettereinrichtung möglichst ruckelfrei und verschleißarm verfahrbar sein, ohne hierfür die Kippstabilität der Klettereinrichtung gegenüber dem Kranturm zu opfern.The present invention has for its object to provide an improved climbing device of the type mentioned above, which avoids the disadvantages of the prior art and the latter develops in an advantageous manner. In particular, the climbing device should be as smooth as possible and low-wear movable, without sacrificing the tilting stability of the climbing device against the crane tower for this purpose.
Erfindungsgemäß wird die genannte Aufgabe durch eine Klettereinrichtung gemäß Anspruch 1 gelöst. Bevorzugte Ausgestaltungen der Erfindung sind Gegenstand der abhängigen Ansprüche.According to the invention, said object is achieved by a climbing device according to claim 1. Preferred embodiments of the invention are the subject of the dependent claims.
Es wird also vorgeschlagen, die längsverfahrbare Führung des Kletterrahmens am Kranturm gegenüber Form- und/oder Maßtoleranzen, die entlang des Verfahrwegs auftreten können, selbst einstellend auszubilden, sodass die genannten Form-und/oder Maßtoleranzen von der längsverfahrbaren Führung kompensiert werden können. Die längsverfahrbare Führung wird hierzu in Querrichtung elastisch ausgebildet, sodass Überstände bzw. Übermaße geschluckt und bei Untermaßen die Führungsflächen nachfahren können, um den Führungsflächeneingriff und damit die Kippstabilität zu erhalten. Erfindungsgemäß besitzt die Führung quer zur Verfahrrichtung des Kletterrahmens elastisch nachgiebig gelagerte und/oder elastisch nachgiebig ausgebildete Querstützelemente. Die genannten Querstützelemente nehmen Querkräfte quer zur Verfahrrichtung des Kletterrahmens und/oder quer zur Längsrichtung des Kranturms auf und stützen den Kletterrahmen in genannter Querrichtung am Kranturm ab, erlauben dabei aber ein Verfahren in Längsrichtung. Wird bspw. beim Aufklettern ein vorspringender Konturabschnitt, bspw. an der Fügestelle zwischen zwei Turmstücken überfahren, kann das entsprechende Querstützelement nachgeben, sodass der Kletterrahmen sanft über die genannte Konturstelle hinwegfahren kann, während umgekehrt bei einem sich zurücknehmenden Konturabschnitt das Querstützelement elastisch nachfährt und den Stützkontakt und damit die Kippstabilität aufrechterhält.It is therefore proposed that the longitudinally movable guidance of the climbing frame on the crane tower be formed in a self-adjusting manner with respect to shape and / or dimensional tolerances that may occur along the travel path, so that the aforementioned dimensional and / or dimensional tolerances can be compensated by the longitudinally movable guide. The longitudinally movable guide is designed to be elastic in the transverse direction, so that supernatants or oversizes swallowed and undercuts the guide surfaces can nachfahren to maintain the guide surface engagement and thus the tipping stability. According to the invention, the guide has transversely to the direction of travel of the climbing frame elastically yielding and / or elastically yielding formed transverse support elements. The said transverse support elements take transverse forces transversely to the direction of travel of the climbing frame and / or transversely to the longitudinal direction of the crane tower and support the climbing frame in said transverse direction at the crane tower, but allow a process in the longitudinal direction. If, for example, when climbing a projecting contour section, For example, run over at the joint between two tower sections, the corresponding cross support element can yield, so that the climbing frame can drive over the said contour point smoothly, while conversely, at a receding contour section, the cross support element elastically nachfährt and maintains the support contact and thus the tipping stability.
In vorteilhafter Weiterbildung der Erfindung können die elastisch nachgiebig gelagerten und/oder ausgebildeten Querstützelemente als Führungsrollen ausgebildet sein, die um eine Drehachse drehbar gelagert sind, die sich quer zur Verfahrrichtung des Kletterrahmens erstreckt. Die elastische Nachgiebigkeit der Führungsrolle quer zu ihrer Drehachse und/oder quer zur Längsrichtung des Turms kann durch elastische Nachgiebigkeit der Führungsrolle selbst, bspw. durch Ausbildung als Gummirolle erzielt werden. Vorteilhafterweise kann alternativ oder zusätzlich aber auch die Drehachse der Führungsrolle quer zur Verfahrrichtung elastisch nachgiebig gelagert sein, sodass eine näherungsweise starre Führungsrolle bspw. aus einem metallischen Werkstoff oder einem Hartkunststoff verwendet werden kann.In an advantageous embodiment of the invention, the elastically yielding and / or formed transverse support elements may be formed as guide rollers which are rotatably mounted about a rotation axis extending transversely to the direction of travel of the climbing frame. The elastic compliance of the guide roller transversely to its axis of rotation and / or transversely to the longitudinal direction of the tower can be achieved by elastic compliance of the guide roller itself, for example. By training as a rubber roller. Advantageously, as an alternative or in addition, however, the axis of rotation of the guide roller can also be mounted elastically yielding transversely to the travel direction, so that an approximately rigid guide roller can be used, for example, of a metallic material or a hard plastic.
In vorteilhafter Weiterbildung der Erfindung können die Führungsrollen bzw. Querstützelemente jeweils einzeln im Sinne einer Einzelradaufhängung elastisch nachgiebig gelagert sein. Grundsätzlich wäre es auch denkbar, zwei oder mehrere der Querstützelemente auf einer Seite des Kletterrahmens hinsichtlich der elastisch nachgiebigen Lagerung zusammenzufassen, bspw. dergestalt, dass sie an einem gemeinsamen, beweglichen Lager- oder Schwingenelement angeordnet sind. Eine hinsichtlich der Ausgleichsbewegungen voneinander unabhängige Einzelaufhängung ermöglicht jedoch eine feinfühligere Anpassung an Formtoleranzen und Belastungsfälle, sodass der Kletterrahmen insgesamt harmonischer verfahrbar ist.In an advantageous development of the invention, the guide rollers or transverse support elements can each be mounted elastically yielding individually in the sense of an independent wheel suspension. Basically, it would also be conceivable to combine two or more of the transverse support elements on one side of the climbing frame with respect to the elastically yielding bearing, for example. Dergestalt in such a way that they are arranged on a common, movable bearing or swing element. However, a respect to the compensatory movements independent suspension individual allows a more sensitive adaptation to dimensional tolerances and load cases, so that the climbing frame is a total of harmonious traversable.
Insbesondere können die Querstützelemente bzw. Führungsrollen jeweils an einem Stützelementeträger befestigt bzw. drehbar gelagert sein, der quer zur Verfahrrichtung des Kletterrahmens beweglich gelagert ist und von der vorgenannten Federeinrichtung in die Abstütz- bzw. Eingriffsstellung vorgespannt sein kann. Ist das entsprechende Stützelement am Kletterrahmen vorgesehen, kann der Stützelementeträger von der Federeinrichtung auf den Kranturm zu vorgespannt sein, sodass das Stützelement gegen den Kranturm gedrückt wird. Grundsätzlich wäre es auch denkbar, entsprechende Querstützelemente an den Turmstücken des Kranturms vorzusehen, wobei dann in diesem Falle das jeweilige Querstützelement auf den Kletterrahmen zuvor gespannt wäre. Eine solche turmseitige Anordnung erfordert jedoch an einer Vielzahl von Turmstücken entsprechende Querstützelemente. Eine kletterrahmenseitige Anordnung der Querstützelemente ist hinsichtlich einer reduzierten Bauteilanzahl deutlich von Vorteil.In particular, the transverse support elements or guide rollers can each be attached to a support element carrier or rotatably mounted, which is mounted transversely to the direction of travel of the climbing frame and can be biased by the aforementioned spring means in the support or engagement position. If the corresponding support element is provided on the climbing frame, the support element carrier can be pretensioned by the spring device onto the crane tower be such that the support element is pressed against the crane tower. In principle, it would also be conceivable to provide corresponding transverse support elements on the tower sections of the crane tower, in which case the respective transverse support element would then be tensioned on the climbing frame beforehand. However, such a tower-side arrangement requires corresponding to a plurality of tower pieces corresponding cross support elements. A kletterrahmenseitige arrangement of the transverse support elements is in terms of a reduced number of components clearly beneficial.
Um eine feinfühlige, rasch ansprechende Querbewegung der Querstützelemente zu ermöglichen, kann der vorgenannte Stützelementeträger, an dem ein jeweiliges Querstützelement bzw. eine entsprechende Führungsrolle gelagert ist, in vorteilhafter Weiterbildung der Erfindung von mehreren Federelementen abgestützt sein, wobei vorteilhafterweise zwei Federelemente auf unterschiedlichen Seiten des Querstützelements an dem genannten Stützelementeträger angreifen können, sodass der Stützelementeträger zusätzlich zu Querbewegungen auch leichte Kippbewegungen ausführen kann.In order to enable a sensitive, rapidly responding transverse movement of the transverse support elements, the aforementioned support element carrier, on which a respective transverse support element or a corresponding guide roller is mounted, be supported in an advantageous embodiment of the invention of several spring elements, advantageously two spring elements on different sides of the transverse support element can engage the said support element carrier, so that the support element carrier can also perform slight tilting movements in addition to transverse movements.
Die Federelemente können dabei mechanisch ausgebildet sein. Alternativ oder zusätzlich können auch pneumatische oder hydraulische Federelemente vorgesehen sein. Es wäre grundsätzlich auch möglich, die Führungsrollen pneumatisch und/oder hydraulisch federnd auszubilden.The spring elements can be mechanically formed. Alternatively or additionally, pneumatic or hydraulic spring elements may be provided. It would also be possible in principle to form the guide rollers pneumatically and / or hydraulically resilient.
In Weiterbildung der Erfindung ist die längsverschiebbare Führung des Kletterrahmens gegenüber dem Kranturm derart ausgebildet, dass die Quernachgiebigkeit der Querstützelemente und/oder die dadurch ermöglichte Quernachgiebigkeit des Kletterrahmens zum Kranturm nur begrenzt ist, insbesondere derart, dass keine nennenswerten Kippbewegungen des Kletterrahmens gegenüber dem Kranturm möglich sind. Ein Quernachgiebigkeitsbegrenzer der Führungsvorrichtung kann dabei unmittelbar den elastisch nachgiebig gelagerten Querstützelementen zugeordnet sein und dafür sorgen, dass die elastische Nachgiebigkeit der genannten Querstützelemente nur begrenzt ist bzw. die Querstützelemente nur einen relativ kleinen, begrenzten Betrag querverstellbar sind. Beispielsweise kann die Querverstellbarkeit bzw. - nachgiebigkeit der elastisch nachgiebig gelagerten Querstützelemente durch Anschläge begrenzt werden, gegen die ein beweglicher Lagerabschnitt der Querstützelemente fährt. Beispielsweise kann die Drehachse der Führungsrollen in einem Langloch geführt sein, das nur eine begrenzte Querverstellbarkeit der Führungsrollen zulässt.In a development of the invention, the longitudinally displaceable guidance of the climbing frame relative to the crane tower is designed such that the transverse compliance of the transverse support elements and / or the transverse mobility of the climbing frame made possible by the crane tower is limited, in particular in such a way that no noteworthy tilting movements of the climbing frame relative to the crane tower are possible , A transverse compliance limiter of the guide device can be assigned directly to the elastically yielding mounted transverse support elements and ensure that the elastic compliance of the said transverse support elements is limited or the transverse support elements are transversely adjustable only a relatively small, limited amount. For example, the Querverstellbarkeit or - yielding the elastically yielding mounted cross support elements Limits are limited, against which moves a movable bearing portion of the transverse support elements. For example, the axis of rotation of the guide rollers may be guided in a slot, which allows only a limited Querverstellbarkeit the guide rollers.
Alternativ oder zusätzlich kann der genannte Nachgiebigkeitsbegrenzer auch weitere Querstützelemente umfassen, die nicht elastisch nachgiebig gelagert bzw. nicht elastisch nachgiebig ausgebildet sind, sondern quer zur Verfahrrichtung des Kletterrahmens im Wesentlichen starr bzw. unnachgiebig ausgebildet sind. Um die vorgenannte Verschleißproblematik und Klemmtendenz durch solche starren Querstützelemente zu vermeiden, können diese zusätzlichen starren Querstützelemente gegenüber den elastisch nachgiebig gelagerten und/oder ausgebildeten Querstützelementen, zumindest wenn sich Letztere in ihrer unausgelenkten Soll- bzw. Neutralstellung befinden, ein Stück weit zurückgesetzt angeordnet sein, sodass die genannten starren, zusätzlichen Querstützelemente außer Eingriff sind, wenn die elastisch nachgiebigen Querstützelemente nicht ausgelenkt sind bzw. sich der Kletterrahmen in einer Neutralstellung befindet, in der die elastisch nachgiebigen Querstützelemente den Kletterahmen halten. Insbesondere können die genannten zusätzlichen starren Querstützelemente zueinander derart an dem Kletterrahmen angeordnet sein, dass sie den Kranturm bzw. ein jeweiliges Turmstück nur mit Luft umgreifen bzw. eine Spielpassung zu den zugehörigen Stützflächen am jeweiligen Turmstück hin bilden.Alternatively or additionally, said compliance limiter may also comprise further transverse support elements, which are not elastically yielding or non-elastically yielding, but are formed substantially rigidly or unyieldingly transversely to the direction of travel of the climbing frame. In order to avoid the aforementioned problems of wear and clamping tendency by such rigid transverse support elements, these additional rigid transverse support elements can be located a bit far from the elastically yielding and / or formed transverse support elements, at least when the latter are in their undeflected desired or neutral position, so that said rigid, additional transverse support elements are disengaged when the elastically yielding transverse support elements are not deflected or the climbing frame is in a neutral position in which the elastically yielding transverse support elements hold the climbing frame. In particular, said additional rigid transverse support elements can be arranged on the climbing frame in such a way that they surround the crane tower or a respective tower section only with air or form a clearance fit to the associated support surfaces on the respective tower section.
Die genannten zusätzlichen, quer zur Verfahrrichtung unnachgiebig angeordneten Querstützelemente können grundsätzlich verschieden ausgebildet sein, bspw. ebenfalls als Führungsrollen ausgebildet sein. In Weiterbildung der Erfindung können die genannten zusätzlichen Querstützelemente aber auch als Gleitlager ausgebildet sein, insbesondere in Form von Gleitblechen, die die Längsgurte bzw. Eckstiele des Kranturms in der genannten Weise mit Spiel umgreifen können.The aforementioned additional transverse support elements, which are unyielding transversely to the direction of travel, can in principle be designed differently, for example, also be designed as guide rollers. In a further development of the invention, said additional transverse support elements can also be designed as sliding bearings, in particular in the form of sliding plates, which can embrace the longitudinal straps or corner handles of the crane tower in the manner mentioned with game.
