Abstract
Description
Die Erfindung betrifft ein Verfahren zum Verbinden mehrerer zylindrischer Elemente des Turms einer Windkraftanlage.The invention relates to a method for connecting a plurality of cylindrical elements of the tower of a wind turbine.
Bei Windkraftanlagen befindet sich ein meist mehrere Tonnen schwerer Generator auf der Spitze eines Turms, der in einzeln aufeinander aufgesetzten Rohrteilen hochgebaut wird, bis die Endhöhe erreicht ist. Die Stahlrohrteile werden meist in einer Werkstattvorfertigung aus mehreren Rohrschüssen zu größeren, einige Meter langen und transportfähigen Teilen zusammengeschweißt. Diese Rohrteile müssen dann vor Ort aufeinandergesetzt und zu einem Turm verschweißt werden.In wind turbines, a generator, usually several tons in weight, is located on the top of a tower, which is built up in individually superimposed pipe parts until the final height is reached. The steel pipe parts are usually welded together in a workshop prefabrication of several pipe sections to larger, several meters long and transportable parts. These pipe parts must then be placed on site and welded into a tower.
Aus
Die Aufgabe besteht darin, bei Montage-Aufbau vor Ort und/oder in der Werkstattfertigung ein mechanisiertes Schweißverfahren zu nutzen, mit dem ein horizontal liegender Fügespalt schweißbar ist.The task is to use a mechanized welding process in assembly assembly on site and / or in the workshop production, with a horizontally lying joint gap is weldable.
Die Aufgabe der Erfindung wird gelöst durch die unabhängigen Patentansprüche. Vorteilhafte Weiterbildungen und Ausgestaltungen der Erfindung sind in den abhängigen Ansprüchen angegeben.The object of the invention is achieved by the independent claims. Advantageous developments and refinements of the invention are specified in the dependent claims.
Mehrere zylindrische Elemente für den Turm einer Windkraftanlage werden miteinander verbunden, indem jeweils zwei Elemente an deren einander zugeordneten Stirnseiten umlaufend miteinander verschweißt werden, wobei zwischen den beiden Elementen ein nahezu paralleler, umlaufender Spalt mit einer Breite von 8–12 mm vorhanden ist.Several cylindrical elements for the tower of a wind turbine are connected to each other by each two elements are welded together circumferentially at their mutually associated end faces, wherein between the two elements, a nearly parallel, circumferential gap with a width of 8-12 mm is present.
Durch das mechanisierte MSG(Metallschutzgas)-Engspalt-Schweißverfahren ist ein schnelleres und kostengünstiges Schweißen möglich.The mechanized MSG (metal inert gas) nip welding process enables faster and less expensive welding.
Bevorzugt beträgt der Schweißnahtöffnungswinkel zwischen den einander zugeordneten Stirnseiten der beiden Elemente mindestens 0,5°. Dadurch ist eine schnelle Schweißverbindung mit hoher Qualität möglich.Preferably, the weld opening angle between the mutually associated end faces of the two elements is at least 0.5 °. This allows a quick weld with high quality.
Bevorzugt wird die beim MSG-Engspalt-Schweißverfahren verwendete Schweißelektrode in der Schweißfuge automatisch nachgeführt, wodurch die Schweißnahtqualität erhöht wird.Preferably, the welding electrode used in the MSG narrow gap welding process is automatically tracked in the welding joint, whereby the quality of the weld seam is increased.
Bevorzugt liegt die Abschmelzleistung des verschweißten Materials zwischen 3 und 6 kg pro Stunde, wodurch die Kosten der Schweißnaht reduziert werden.Preferably, the deposition rate of the welded material is between 3 and 6 kg per hour, which reduces the cost of the weld.
Bevorzugt ist die Position der umlaufenden Schweißfuge während des Schweißens horizontal ausgerichtet, wodurch auch vertikal übereinander angeordnete, rohrartige Elemente vor Ort, d. h. am Ort der Windkraftanlage, verschweißbar sind. Somit ist dieses Verfahren in horizontaler Fugenposition zum Verbinden der aufeinander gestellten Rohrteile einer Windkraftanlage vor Ort anwendbar. In Verbindung mit einer Engspaltversion des MSG-Schweißverfahrens lassen sich zusätzliche technologische und wirtschaftliche Vorteile erschließen.Preferably, the position of the circumferential weld joint during welding is aligned horizontally, whereby also vertically stacked, tubular elements in place, d. H. at the site of the wind turbine, are weldable. Thus, this method is applicable in the horizontal joint position for connecting the stacked pipe parts of a wind turbine on site. In conjunction with a narrow gap version of the MSG welding process, additional technological and economic advantages can be achieved.
