Description
Die vorliegende Erfindung betrifft eine Anordnung zum Befestigen von Bauelementen an einer metallischen Wand eines Turmes einer Windenergieanlage, einen Turm einer Windenergieanlage sowie eine Windenergieanlage. The present invention relates to an arrangement for fastening components to a metallic wall of a tower of a wind turbine, a tower of a wind turbine and a wind turbine.
Windenergieanlagen umfassen zumeist einen in einem Fundament verankerten Turm, ein auf dem Turm drehbar gelagertes Maschinenhaus und einen an dem Maschinenhaus angebrachten Rotor. Der Turm ist dabei häufig ein Stahlrohrturm oder ein Hybridturm mit einem Stahlrohrturmabschnitt. Der Stahlrohrturm wird zumeist aus gewalzten Stahlblechen hergestellt, die miteinander verbunden, insbesondere verschweißt und/oder verschraubt werden. Wind turbines usually comprise a tower anchored in a foundation, a nacelle rotatably mounted on the tower, and a rotor attached to the nacelle. The tower is often a steel tube tower or a hybrid tower with a tubular steel tower section. The tubular steel tower is usually made of rolled steel sheets, which are connected together, in particular welded and / or bolted.
Der Turm dient, neben dem Tragen des Maschinenhauses, auch dazu, Einrichtungen aufzunehmen, die für den Betrieb und den Zugang zur Windenergieanlage erforderlich sind, beispielsweise Kabel, Leitern oder Plattformen zur Wartung von Schraubverbindungen. Diese Bauelemente bzw. Halter dafür werden häufig an Befestigungselementen angebracht, die an die Turmwand geschweißt sind. Bekannt sind Schweißbuchsen mit einem Gewinde, die mittels Kehlnähten mit dem Blech der Turmwand verbunden werden. The tower, in addition to supporting the machine house, also serves to house equipment required for operation and access to the wind turbine, such as cables, ladders, or screw maintenance platforms. These components or holders are often attached to fasteners that are welded to the tower wall. Welding bushes are known with a thread, which are connected by fillet welds with the plate of the tower wall.
Beim Schweißen wird der Grundwerkstoff der Verbindungspartner aufgeschmolzen, was zu Materialveränderungen im Bereich der Schweißverbindung führt. Die aus der Kerbwirkung der Schweißverbindung resultierende Schwächung der Tragfähigkeit des Stahls muss bei der Auslegung des Turmes berücksichtigt werden, indem die Turmwand verstärkt wird, das wiederum ist technisch und wirtschaftlich nachteilig. Deshalb wird seit langem nach alternativen oder verbesserten Möglichkeiten gesucht, um Bauelemente am und im Turm einer Windenergieanlage zu befestigen. During welding, the base material of the connection partners is melted, which leads to material changes in the area of the welded connection. The weakening of the bearing capacity of the steel resulting from the notch effect of the weld must be taken into account in the design of the tower by reinforcing the tower wall, which in turn is technically and economically disadvantageous. Therefore, for a long time has been looking for alternative or improved ways to attach components on and in the tower of a wind turbine.

Darstellung der Erfindung Presentation of the invention
Aufgabe der Erfindung ist es, eine Anordnung zum Befestigen von Bauelementen an einer metallischen Wand eines Turmes einer Windenergieanlage bereitzustellen, die die genannten Nachteile von Schweißverbindungen vermeidet. The object of the invention is to provide an arrangement for securing components to a metallic wall of a tower of a wind turbine, which avoids the said disadvantages of welded joints.
Die Aufgabe wird gelöst durch eine Anordnung zum Befestigen von Bauelementen an einer metallischen Wand eines Turmes einer Windenergieanlage, wobei die Anordnung ein Befestigungselement aufweist, das mit der metallischen Wand verbunden wird und an dem ein Bauelement befestigt werden kann. Das Befestigungselement wird stoffschlüssig mit der Turmwand verbunden, und zwar durch Löten, insbesondere durch Hartlöten. Beim Löten müssen die Turmwand und das Befestigungselement erwärmt werden. In den Spalt zwischen den Verbindungspartnern wird ein Lot als Zusatzwerkstoff gebracht und aufgeschmolzen. Die Schmelztemperatur beispielsweise des Hartlotes liegt unter der Schmelztemperatur der Grundwerkstoffe, so dass diese nicht aufgeschmolzen werden. Durch die Kapillarwirkung wird eine Benetzung der Oberflächen der Verbindungspartner bewirkt, die durch ein Flussmittel weiter verbessert werden kann. Im Bereich der Benetzung findet eine Wechselwirkung an den Grenzflächen zwischen dem Grundwerkstoff und dem Hartlot statt und es bildet sich durch Diffusion von Atomen aus Grundwerkstoff und Lot eine Übergangszone, die zu einer stoffschlüssigen metallischen Verbindung führt. Das zu befestigende Bauelement kann in bekannter Weise, beispielsweise durch Schrauben, mit dem Befestigungselement verbunden werden. The object is achieved by an arrangement for fastening components to a metallic wall of a tower of a wind power plant, the arrangement having a fastening element which is connected to the metallic wall and to which a component can be fastened. The fastening element is materially connected to the tower wall, by soldering, in particular by brazing. During soldering, the tower wall and the fastening element must be heated. In the gap between the connection partners, a solder is brought as an additional material and melted. The melting temperature, for example, of the brazing alloy is below the melting temperature of the base materials, so that they are not melted. The capillary effect causes a wetting of the surfaces of the connection partners, which can be further improved by a flux. In the area of wetting, an interaction takes place at the interfaces between the base material and the brazing material, and diffusion of atoms of base material and solder forms a transition zone, which leads to a cohesive metallic connection. The component to be fastened can be connected in a known manner, for example by screws, with the fastening element.
Der Lötspalt weist vorzugsweise eine Breite von 0,05 bis 0,5 mm auf, so dass sich der notwendige Kapillardruck zum ausreichenden Benetzen der Oberflächen der Verbindungspartner ausbilden kann. The soldering gap preferably has a width of 0.05 to 0.5 mm, so that the necessary capillary pressure for sufficiently wetting the surfaces of the connection partners can form.
Als Befestigungselemente werden vorzugsweise Lötbuchsen, Lötbleche oder Lötbolzen verwendet. Bevorzugt sind die Befestigungselemente im Bereich der Lötverbindung vergrößert, so dass die Krafteinleitung verbessert wird und die Verbindung größere Kräfte aufnehmen kann; ein Lötblech beispielsweise weist dazu Auslaufzehen auf. Falls erforderlich, werden mehrere Befestigungselemente nebeneinander an der Turmwand angebracht, so dass eine größere Last aufgenommen werden kann als durch ein einzelnes Befestigungselement. As fastening elements soldering, soldering or soldering bolts are preferably used. Preferably, the fastening elements are enlarged in the region of the solder joint, so that the introduction of force is improved and the connection can absorb larger forces; For example, a brazing sheet has run-off toes. If necessary, a plurality of fasteners are mounted side by side on the tower wall, so that a larger load can be accommodated than by a single fastener.
Für eine möglichst gleichmäßige Belastung ist in einer Ausführungsform eine Brücke zwischen mindestens zwei Befestigungselementen angeordnet. In einer weiteren Ausführungsform ist eine Brücke einseitig mit mindestens einem Befestigungselement verbunden, wobei sich die Brücke unterhalb des Befestigungselements an der Turmwandung abstützen kann. For a uniform possible load is in one embodiment, a bridge between arranged at least two fasteners. In a further embodiment, a bridge is connected on one side with at least one fastening element, wherein the bridge can be supported below the fastening element on the tower wall.
