Definitions

  • the present invention relates to handling wind turbine components, and more specifically to a lifting tool, system, and method for handling wind turbine tower sections.
  • Wind turbines have long been used to convert the kinetic energy of wind into mechanical energy that drives a generator, thereby producing electricity. Over time, there has been a significant increase in the overall size of these machines because of the desire to capture more of the wind's available energy. Nevertheless, there remain sites better suited for smaller wind turbines due to their wind conditions, local restrictions, or other limiting factors. A great variety of wind turbine sizes now exist as a result, which makes handling their components very challenging particularly in terms of transportation and storage.
  • the lifting tool may actually include a plurality of inserts configured to be positioned and retained in and/or over the adaptor hole. At least some of the inserts have bolt holes arranged along a second radius of curvature different than the first radius of curvature. This enables the lifting tool to be used to handle a tower section that has a different size. A different insert is simply selected. Thus, the lifting tool can easily be used to handle different sizes of tower sections without significant reconfiguration. All that is needed is different sets of inserts with bolt holes arranged along different radii of curvature. The different sets of inserts may also have different bolt hole patterns, such as single and double rows of bolt holes, to further accommodate different flange designs.
  • the system for handling one or more wind turbine tower sections comprises first and second lifting tools with the construction described above.
  • a support member may be coupled to the first and second lifting tools so as to extend therebetween.
  • This support member may have an adjustable length to facilitate use with different sizes of tower sections.
  • the method for handling one or more wind turbine tower sections involves providing at least one lifting tool with the construction described above.
  • the lifting tool is coupled to a first tower section by positioning the base of the lifting tool over the flange of the first tower section.
  • the insert to be used with the lifting tool is positioned and retained in and/ or over the adaptor hole before or after this step.
  • the base is eventually secured to the end of the first tower section by bolting the insert to the flange.
  • the first tower section is lifted with the lifting tool.
  • Two or more lifting tools may be provided, along with a support member extending between them, as mentioned above.
  • Fig. 1 is a perspective view of a wind turbine tower section and one embodiment of a system for handling the tower section.
  • Fig. 2 is a perspective view of the system of Fig. 1 .
  • Fig. 3 is an enlarged view of a lifting tool used in the system of Fig. 1 .
  • Fig. 4 is an exploded perspective view of the lifting tool shown in Fig. 3 .
  • Figs. 1 and 2 show one embodiment of a system 10 for handling wind turbine tower sections.
  • the system 10 includes one or more lifting tools 12 for handling a tower section 14 and a support bar or member 16 to which the lifting tools 12 are coupled. These components and use of the system 10 will be described in further detail below.
  • the details of the tower section 14 will also be described, but only for background purposes as the system 10 may be used to handle other tower sections and other types of towers.
  • the tower section 14 part of tubular steel tower and constructed from several steel rings welded together.
  • a flange 22 with bolt holes 24 is provided on a first end 26 of the tower section to facilitate attachment to other tower sections or to a foundation.
  • a second end (not shown) of the tower section 14 may have a similar arrangement with a flange.
  • the tower section 14 is slightly conical such that the flange 22 on the first end 26 extends along a first radius of curvature and the flange on the second end extends along a second radius of curvature.
  • the tower section 14 may alternatively be cylindrical with both flanges extending along similar radii of curvature.
  • the lifting tool 12 includes a bracket 30 and insert 32.
  • the bracket 30 has a base 34, an adaptor hole 36 extending through the base 34, and at least two walls 38 extending upwardly from the base 34.
  • first and second walls 38a, 38b located on opposite sides of the adaptor hole 36 are provided.
  • the base 34 and walls 38 are constructed from plates or other pieces of metal (e.g., steel) welded together to define the desired structure of the bracket 30.
  • the bracket 30 may be cast from a metal (e.g., iron) so that the base 34 and walls 38 are formed together.
  • Other ways of constructing the bracket 30 will be appreciated by skilled persons.
  • the insert 32 is configured to be at least partially positioned and retained in and/or over the adaptor hole 36. This may be achieved by designing the insert 32 with appropriate geometry. For example, and as shown in Fig. 5 , the insert 32 may have a head or top portion 40 larger than the adaptor hole 36 and a neck or body portion 42 shaped to fit in the adaptor hole 36. Thus, the head portion 40 rests against a surface 44 ( Fig. 4 ) of the bracket 30 to prevent the insert 32 from being pushed or pulled through the adaptor hole 36 when the insert 32 is used with the bracket 30. Skilled persons will appreciate other geometries providing the same effect, such as designing the adaptor hole 36 and insert 32 with tapered profiles. Alternatively or additionally, the insert 32 may be retained by separately securing the insert 32 to the bracket 30 with bolts 46 or other conventional fasteners (e.g., clamps, latches).
  • bolts 46 e.g., clamps, latches
  • the insert 32 includes one or more bolt holes 50 arranged along a radius of curvature corresponding to that of one of the flanges 22 ( Fig. 1 ; measured at the bolt holes 24) when the insert 32 is positioned in the adaptor hole 36.
  • the bolt holes 50 are arranged along the first or second radius of curvature mentioned above.
  • the spacing of the bolt holes 50 also corresponds to the spacing of the bolt holes 24. This matching of curvature and spacing enables the bolt holes 50 to be aligned with the bolt holes 24 so that the lifting tool 12 may be secured to the flanges 22 via bolts (not shown) extending through the insert 32.
  • the system shown in Figs. 1 and 2 includes first and second lifting tools 12a, 12b.
  • the support member 16 to which the first and second lifting tools 12a, 12b are coupled has an adjustable length.
  • the support member 16 may comprise telescopic tubes.
  • the adjustable length ensures that the support member 16 may be used with the first and second lifting tools 12a, 12b on tower sections with different diameters. This feature of accommodating different tower sections will be described in further detail below, after describing a method for handling the tower section 14 with the system 10.
  • the first lifting tool 12a is coupled to the tower section 14 in the manner described above.
  • the base 34 of the lifting tool 12 is positioned over the flange 22 of the tower section 14.
  • the insert 32 is then positioned and retained in and/or over the adaptor hole 36 in the base 34 (unless this step was already done previously).
  • the base 34 is secured to the first end 26 of the tower section by bolting the insert 32 to the flange 22.
  • the tower section 14 is lifted with the first and second lifting tools 12a, 12b.
  • This may be accomplished by coupling slings 66 to the first and second lifting tools 12a, 12b, as schematically shown in Fig. 1 .
  • the slings 66 are wrapped around the gripping elements 60 and then hooked onto or otherwise secured to a lifting component (not shown), such as a hook of a crane.
  • each lifting tool 12 there may be a plurality of inserts 32 configured to be positioned and retained in and/or over the adaptor hole 36. At least some of the inserts 32 have bolt holes arranged along a radius of curvature different than the first radius of curvature.
  • one of the initial steps would be to select inserts 32 for the first and second lifting tools 12a, 12b with a radius of curvature corresponding to the radius of curvature of the flange 22 of the tower section 14.
  • the first and second lifting tools 12a, 12b may be removed and used to handle a second tower section that has a different diameter. This involves selecting an insert 32 for each of the first and second lifting tools 12a, 12b with a radius of curvature (of the bolt holes) corresponding to the radius of curvature of a flange of the second tower section.
  • the system 10 provides more than just an easy means of securing a lifting tool to a wind turbine tower section.
  • the ability to accommodate different inserts enables the system 10 to be used for various sizes of tower sections without significant reconfiguration.
  • the design of the system itself has additional benefits.
  • the system 10 provides the above-described flexibility without having to incorporate adjustable locking elements in the lifting tools 12. The result is a reliable, simplified construction that can be economically produced.
