Abstract
Konstruktionselemente von Windkraftanlagen werden zunächst mit Stahlseilen verbunden, die durch Bohrungen für die späteren Flanschverbindungen gefädelt sind, um auch bei bewegten Elementen eine Führung zu fluchtenden Schraubverbindungen zu erzielen und dann fixiert. Dazu weisen die Stahlseile eine daran geschweisste Gewindestange auf, die mittels einer Sechskant-Einformung verschraubbar ist. Construction elements of wind turbines are initially connected to steel cables, which are threaded through holes for the later flange, to achieve even with moving elements a guide to aligned screw and then fixed. For this purpose, the steel cables on a welded threaded rod, which can be screwed by means of a hexagonal indentation.
Description
GEGENSTAND DER ERFINDUNGSCOPE OF THE INVENTION
Gegenstand der Erfindung sind Stahlseile mit angefügten Schraubbolzen, die zur Führung weiterer Montageelemente zunächst in den Flansch der Hauptwelle, bei separater Montage der einzelnen Flügel auch in die Aufnahmen der Rotorblätter eingeschraubt werden. An ihnen selbst, oder durch Sie als Führung werden dann die zu montierenden Elemente zentriert und befestigt.The invention relates to steel cables with attached bolts, which are first screwed into the flange of the main shaft to guide other mounting elements in a separate assembly of the individual wings in the recordings of the rotor blades. On themselves, or through you as a guide, the elements to be mounted are then centered and fastened.
HINTERGRUND DER ERFINDUNG / ZU LÖSENDES PROBLEMBACKGROUND OF THE INVENTION / PROBLEM TO BE SOLVED
Die Montage der Rotoren an die Türme bzw. Gondeln von Windkraftanlagen ist bisher schon an Land problematisch und kann nur bei Windstille ausgeführt werden (Windgeschwindigkeit maximal 6m/sek), die an den gewählten Standorten für Windkraftanlagen naturgemäß selten ist. Die schwierige Terminierung und das oft enge Zeitfenster sind ein Hauptgrund für Verzögerungen und Kostensteigerungen beim Aufbau. Dies trifft umso mehr Offshore-Anlagen zu, weil hier mit kurzfristigem Wetterumschwung, Sturm und Wellengang zu rechnen ist.The assembly of the rotors to the towers or nacelles of wind turbines is already problematic on land and can only be carried out in calm conditions (wind speed maximum 6m / sec), which is naturally rare at the selected locations for wind turbines. The difficult scheduling and the often narrow time window are a major reason for delays and cost increases in the construction. This applies even more to offshore wind turbines, because short-term weather changes, storms and waves are to be expected here.
Auch an Land entstehen durch unterschiedliche Witterungsverhältnisse Risiken, wie unkalkulierbare Transportkosten (weil oft eine Neubeantragung von Sondergenehmigungen, Straßensperren, Begleitfahrzeuge usw. erforderlich ist) und Montagefirmen die geplanten Termine nicht einhalten können.Also on land caused by different weather conditions risks, such as incalculable transport costs (because often a new application of special permits, road blocks, support vehicles, etc. is required) and assembly companies can not meet the planned deadlines.
Zudem bestehen bei den bisher gegebenen Montagebedingungen hohe Unfallrisiken durch mögliche unkalkulierbare Bewegungen der zu montierenden Elemente an Kränen und Hebezeugen. Daher sind Quetschungen, Knochenbrüche und Stürze häufiger, als auf anderen BaustellenIn addition, there are high accident risks in the previously given assembly conditions by possible incalculable movements of the elements to be mounted on cranes and hoists. Therefore, bruising, fractures and falls are more common than on other sites
AUFGABE DER ERFINDUNGOBJECT OF THE INVENTION
Es ist daher Aufgabe vorliegender Erfindung, die Montagearbeiten zu vereinfachen und zubeschleunigen und damit die Unfallgefahr zu verringern.It is therefore an object of the present invention to simplify and accelerate the assembly work and thus reduce the risk of accidents.
LOSUNG / ERFINDERISCHER SCHRITTSOLUTION / INVENTIVE STEP
Die erfindungsgemäße Lösung besteht darin, im Gegensatz zum Stand der Technik nicht die einzelnen Elemente, wie Turm, Gondel und Flügelelemente unverbunden zu montieren, oder zu versuchen, sie vor Ort „frei schwebend“ fluchtend zusammenzusetzen, sondern durch Seilverbindungen, die durch die Schraublöcher der zu verbindenden Elemente geführt sind, diese zu stabilisieren, fluchtend aneinander zu führen und zu fixieren..The solution according to the invention is, unlike the prior art, not to mount the individual elements, such as tower, nacelle and wing elements unconnected, or to try to assemble them "floating" on the spot, but by cable connections through the screw holes of to be connected elements are led to stabilize them, to guide and fix in alignment ..

US 5.462.411 - JPH05296192 (A) schlägt vor, das Montageproblem von Windkraft-Flügeln durch ein Zwischenglied zu lösen, das an Schaft und Blatt angebracht ist, die getrennt zugeführt und an der Nabe verbolzt werden. Dennoch müsste as Rotorblatt erst ebenso genau positioniert werden, nur geht die Montage und die Fixierung des Anstellwinkels der Rotorblätter damit vermutlich schneller.

US 5,462,411 - JPH05296192 (A) proposes to solve the wind turbine blade mounting problem by means of an intermediate member attached to the stem and blade, which are fed separately and bolted to the hub. Nevertheless, the rotor blade would have to be positioned just as accurately, but the assembly and fixation of the pitch of the rotor blades is probably faster.
Insgesamt ist somit keine Lösung zu erkennen, die Ansätze bieten, die Montage von Winkkraft-Rotoren und insbesondere deren schwierige Zentrierung bei der Montage unter den meist unwirtlichen und instabilen Umständen wesentlich zu erleichtern oder zu beschleunigen.Overall, therefore, no solution can be seen, the approaches offer to facilitate the assembly of Winkkraft rotors and in particular their difficult centering during assembly under the most inhospitable and unstable circumstances significantly or accelerate.
