Definitions

  • the invention relates to an attachment for attachment of attachments to a tower inner wall of a wind turbine according to the features of the preamble of claim 1.
  • Wind turbines are highly constructed structures whose power-generating components are arranged at the top of a towering tower in a nested engine house there. Not only because of the high weight loads of the components arranged in the machines, but also because of other loads, in particular the back pressure of the oncoming wind, the towers of wind turbines are exposed to high loads. This is all the more so as that modern wind turbines with ever higher outputs must be sized larger and thus built higher.
  • towers of wind turbines are often made of screwed together or otherwise connected annular metal elements, typically steel elements formed.
  • annular metal elements typically steel elements formed.
  • attachments In the interior of the tower, for example, in order to allow walking on different levels or to support components, attachments must be arranged and fixed to the tower inner wall. In principle, it would be conceivable and possible to make such determinations by attaching openings in the tower wall and passing screws, rivets or the like, or to weld add-on components, such as platforms to be mounted at different heights in the tower interior, directly to the tower wall.
  • the stability of the tower reduced overall.
  • the tower wall would have to be formed in accordance with greater strength, not only because of the higher material costs, but also because of the increased weight and the associated costs in transport and installation of the system and in the Design of the foundation and the like. Is undesirable.
  • a welding sleeve 1 is a substantially cylindrical element with a central bore 2 of constant diameter.
  • the central bore 2 is provided with an internal thread 3.
  • This welding sleeve 1 is attached with an end face to the tower wall T and welded with attachment of a weld 4 with the tower wall T. This welding takes place by means of material input, e.g. over a welding wire.
  • an angle W can now be determined by means of a screw S on a first leg.
  • an attachment e.g. a platform P stored and connected to the angle W in a suitable manner, e.g. welded, bolted, riveted or the like.
  • Such a construction has the advantage that in particular peak loads on the attachment, e.g. load the platform P and are introduced from this on the connecting structure in the tower wall T, not completely load on the tower wall T, but are attenuated and intercepted by the flexibility of the angle W.
  • the weakening of the tower wall T thus produced at the weld 4 is less than in a case where e.g. the platform P would have been welded directly to the tower wall T.
  • the essential realization of the invention is that a flexible Inclusion of peak loads occurring in particular by an inventive attachment element and keeping the entry of these loads in the welded connection to the tower inner wall is given in the region of the first, to be welded to the tower inner wall end face of the attachment this has in cross-section an entire material thickness which is less than an entire Material thickness in a displaced in the direction of the second end face cross-section.
  • the attachment element may have any possible shape, it may be different than in the prior art not sleeve-shaped, but substantially solid or with introduced from one or both end faces blind holes.
  • the outer diameter of the attachment can be consistent throughout, the attachment also be cylindrical; just as well, the outer diameter may change, for example, have an offset. It is only important that compared with a cross-section in the region of the first end face total existing material thickness in the direction of the second end face a cross-section is present, which has a higher or greater material thickness in total than the total material thickness in the region of the cross section of the first end face.
  • the attachments to be determined can be set in any way. You can either load directly on the attachment or over-placed elements, such as the angle used in the prior art.
  • the part to be attached to the attachment itself can be screwed, welded or otherwise connected to it.
  • the attachment can have a continuous longitudinal bore.
  • This longitudinal bore is advantageously provided in a region of the first end face with a section with an enlarged diameter.
  • This expanded diameter is particularly advantageously led over at least 1/3 of the total length of the attachment measured as the distance from the first end face to the second end face.
  • an attachment according to the invention may advantageously have an internal thread into which a screw customary for this connection technology can be guided.

  • FIGS. 2 and 3 show a first exemplary embodiment of an attachment according to the invention, while FIG. 4 shows further possible variants.
  • the first embodiment of an attachment element 10 according to the invention shown in Figures 2 and 3 is formed substantially similar to the known from the prior art weld sleeve 1.
  • the attachment element 10 is substantially cylindrical in construction with a preferably circular cross-sectional outer contour. It has over its length consistent outer dimensions and guided in the interior in the longitudinal direction of the attachment element 10 central bore.
  • the central bore 12 is provided with a widening in a section 14 and has so here on a larger diameter.
  • the wall 15 is weakened in this section against the strength outside of this section and of lesser strength.
  • the overall thickness of the wall in a cross-section is thus smaller than in a cross-section, displaced in the direction of the end of the installation element 10 opposite the first end face, through a region, in which the bore 12 has the smaller diameter.
  • the central bore 12 is provided with an internal thread 13 for screwing in a screw as used in the prior art S.
  • the weld 4 extends outside around the outer wall of the
  • the add-on element 10 according to the invention is shown in a comparable construction to the prior art with a screwed-on to the attachment element 10 angle element W and the platform P deposited thereon.
  • other methods of attachment can be chosen here. It is crucial that by the targeted weakening of the material of the attachment element 10 in the region of the first end face in the connection structure, a higher flexibility is created, which reduces the jump in stiffness in the storm shell and thus justifies the division into a higher notch class.
  • Fig. 3 is an enlarged view, only a portion of

  • the wall thickness D is so far in about 7 mm, the reduced wall thickness d is fixed in this embodiment at 5 mm.
  • Attachment elements 20, 30 and 40 are shown as they are fixed to a tower inner wall T via welds 4, which are also made by means of a classic welding process with material entry and extending outside around the outer wall of the respective attachment element 20, 30, 40 around.
  • welds 4 Common to all shown here further add-on elements 20, 30 and 40 is a on the tower wall remote second end face introduced bore with an internal thread 3. In this can be added screws in the usual way.
  • all of the attachments shown 20, 30 and 40 at the first, on the weld 4 fixed to the tower wall T end face face a cross-section with respect to a comparison cross-section, which is moved in the direction of the second end face, lower total material thickness and have so in this area increased flexibility.
  • this material thinning has been achieved by reducing the outer diameter
  • the add-on element 30 is designed very much like the add-on element 10.
  • the attachment member 30 only the bore inside is not performed.
  • the attachment element 40 has an outer diameter that enlarges toward the first end face, it is provided with a significantly widened bore in the region of this first end face, so that material thinning is also obtained here, which leads to an increase in flexibility.
  • the embodiment of the attachment 10 is preferred, especially since it is easy and simple to manufacture. After inserting the longitudinal bore this must be extended in only a single step on the side of the first end face, typically in a machining operation, for example by drilling or turning. A change in the outer diameter, as required by the add-on elements 20 and 40, entails a higher processing outlay.

Abstract

L'invention concerne un élément de montage pour la fixation de pièces rapportées (P) sur la paroi intérieure métallique de pylône (T) d'un pylône d'un aérogénérateur, avec une première face frontale destinée à être soudée sur la paroi intérieure de pylône (T) et une deuxième face frontale, opposée à la première, destinée à fixer une pièce rapportée (P). Afin d'obtenir une moindre sollicitation de la liaison par soudure entre cet élément de montage et la paroi du pylône et de classer ainsi ce point de liaison dans une classe supérieure de résistance à la fatigue, il est proposé qu'un tel élément de montage possède au niveau de la première face frontale une épaisseur totale de matériau en coupe qui est réduite par rapport à une épaisseur totale de matériau dans une coupe décalée dans la direction de la deuxième face frontale.
