  • the present invention relates to an assembly tool for assembling a spar for a wind turbine.
  • a spar acts as a reinforcing beam in a wind turbine blade.
  • the spar is located between two shell parts, one defining a windward side shell part and the other one defining a leeward side shell part.
  • the spar is located in the cavity between the two wind turbine shell parts and extends substantially throughout the shell cavity in order to increase the strength of the wind turbine blade.
  • composite materials are often used for spars to be used in wind turbine blades, since such blades are exposed to varying loads with high peeks.
  • a spar is a tubular element being manufactured by the use of a male mould, e.g. by winding a suitable material around a mandrel or a similar core element.
  • the inner geometry of the final tubular element is defined by the geometry of the mandrel or core, thus allowing for a well-defined inner geometry.
  • the outer geometry of the final tubular element is less well-defined as the effect of even small variations on the mandrel or core and/or small variation on the innermost layers of the winded material are increased with the number of windings.
  • a spar is sometimes made from two separately moulded elements which subsequently are joined in order to define a tubular element.
  • a height adjustment element can be applied to assure that the final spar fits in the cavity between the two shell parts defining the wind turbine blade.
  • the spar comprises at least four parts.
  • the invention provides an assembly tool for assembling a spar for a wind turbine blade, the spar comprising at least two caps and two webs, each cap forming an intermediate portion between two end portions, where the end portions each forms a cap joint surface portion along a longitudinal extending edge of the end portion and the intermediate portion forms an outer surface portion of the spar, and each web having web joint surface portions along opposite and longitudinally extending edges, the tool comprising a cap support for holding caps, a web support for holding webs and an assembly structure facilitating positioning of the supports relative to each other.
  • the at least four spar parts, the caps and the webs may be connected by connecting the joint surface portions of the caps with the joint surface portions of the web to form a tubular element which may constitute part of the longitudinal strength of the wind turbine blade, thus being part of the reinforcement of the blade.
  • tubular element in this connection meant a hollow element with an elongated shape.
  • the shape may be non-uniform.
  • the outer geometry may be of a substantially rectangular shape, a partly circular shape, an oval shape or any other shape.
  • the inner geometry may be different from the outer shape, thus defining a tubular element in the form of an elongated ring of an arbitrary shape.
  • the spar may be substantially rectangular, e.g. with rounded corners.
  • the area of the cross section may decrease from the root end to the tip end along the length of the spar to have a spar which fits a wind turbine blade having a decreased size at the tip end compared to the root end.
  • the width of the spar may increase locally to increase strength and stiffness of the spar locally.
  • the spar may thus be approximately conical, i.e. may have a base which is substantially circular transforming into an approximately rectangular shape with rounded corners and with sides which taper towards each other.
  • the spar may have a length of approximately 45 metres, a maximum width of approximately 1.0 metres, and a maximum height of approximately 0.8 metres. Compared hereto the minimal width of the spar may be approximately 100 millimetres. It should be understood that this is only one example of a spar. Other spars being both smaller and larger may also be used depending of the wind turbine blade to be manufactured.
  • the at least two spar caps may form an upper and a lower part of a spar being substantially rectangular, whereas the webs may form substantially vertical connections here between when connected at the joint surface portions, thereby providing a spar of at least four separate elements which may be connected to form a spar with a well-defined outer geometry ensuring a better match between the blade shells and the spar.
  • the outer surface portion When positioning the spar between two shell parts of a wind turbine blade, the outer surface portion may form a contact face for assembly with a blade shell.
  • the spar may be attached to the shell part by adding an adhesive to the outer surface portion of each of the caps and subsequently position the shell parts around the spar so that a part of an inner surface of the each of the shell parts is attached to the outer surface portion of each of the caps.
  • the outer surface portion may be adapted to form part of an aerodynamically active surface of a wind turbine blade.
  • the spar may not be completely encapsulated within the shell parts.
  • the assembly tool comprises a cap support for holding caps, and a web support for holding webs during assembling of the spar. Furthermore, the tool comprises an assembly structure facilitating positioning of the supports relative to each other.
  • the cap support may comprise an individual cap support structure for each cap.

  • As the joint surface portions of the webs may be connected to the cap joint surface portions by arranging the webs so that they extend between the end portions of the caps with the web joint surface portions overlapping the cap joint surface portions, the webs may be pressed towards the caps during assembling of the spar. When pressing the webs towards the caps, the caps may be deformed, as the end portions of each of the caps may be pressed towards each other whereby the angle may change towards an angle of approximately 90 degrees.
  • the webs may be pressed towards the end portions of the caps by the tool when the supports have been positioned relative to each other by the use of the assembly structure.
