Definitions
- the present invention relates to a method and a connecting piece for assembling a first and a second section of an arm, preferably a windmill arm, where the sections are joined together in extension of one another in order thus to form at 0 least a part of an arm.
- the length of windmill arms increases in line with the nominal power of the windmill.
- arms with lengths of 60 meters or more are used.
- Such mill arms are difficult to transport on account of this length. It is therefore desirable for it to be possible to transport such arms in sections.
- windmill arms can be manufactured in 5 sections, which are subsequently assembled to form a whole.
- the patent EP 1 244 873 describes a method in which two arm sections in a butt joint are held together with longitudinal metal straps which are prestressed by rotating eccentric bolts.
- the disadvantage of this method is that the prestressing tolerance is limited and that it is difficult to ensure correct prestressing on account of the great friction in the strap joint.
- WO 04015265 describes a method in which two arm sections in a butt joint are held together with a glued-on overlapping plate shaped like an arm profile.
- the disadvantage of this method is that it involves making a glued joint under field conditions with the associated risks of it not being possible, because of the surrounding conditions, for the joint to be made to the same quality as if it were made under controlled conditions.
- the arm cannot be separated again, for example in the event of damage which is limited to the outer arm alone, and, in the event of being transported away, the arm joint has to be cut through destructively.
- the object of the invention is to provide a reproducible, safe and maintenance-friendly method for assembling arms, preferably windmill arms, in sections and to describe an apparatus for use in this method.
- This object is achieved by a method for assembling a first and a second arm section in extension of one another in order thus to form at least a part of an arm, preferably a windmill arm, the method comprising one or more connecting pieces being mounted between two arm sections.
- Each connecting piece is provided with a first flange for attachment to the end surface of the first arm section and a second flange for attachment to the end surface of the second arm section, the first and the second flange being firmly interconnected, the first and the second flange each being provided with at least one hole for one or more bolts, and this bolt or these bolts connecting each arm section to the adjacent flange.
- each of the two arm sections means for fastening one or more bolts are provided in each of the two arm sections.
- a connecting piece in the form of one or more modules provided with a first flange for attachment to the end of the first arm section and a second flange for attachment to the end of the second arm section, the first and the second flange being firmly interconnected.
- the first and the second flange are each provided with at least one hole for a bolt.
- the means by which an arm section retains one or more bolts can be brought about by providing the arm section with transverse holes in which nuts for the bolts can be fitted.
- a nut can be made in the form of a cylindrical body with a diameter which is adapted to the diameter of the transverse hole in the arm section and with a transverse threaded hole for receiving the bolt which is fitted in the connecting piece.
- bolts or nuts can be embedded firmly in the arm section.
- the arm section can be provided with one or more bodies which each have two or more threaded holes for retention of bolts.
- the material thickness in the arm section can advantageously be increased up to the connecting surface against the connecting piece, so good safety is achieved in the stress level in the arm material where transverse holes are made for receiving nuts for arm assembly.
- the two flanges of the connecting piece can be interconnected by an intermediate piece, for example in such a way that the flanges and the intermediate piece form a U-profile in cross section.
- a reinforcement can be made at the side of each hole, for example in the form of one or more ribs.
- the two flanges of the connecting piece can be interconnected by one or more intermediate pieces in the nature of ribs, the ribs alone constituting the firm connection between the flanges.
- the connecting piece can be formed with an outer contour which essentially follows the contour of the arm. If the connecting piece is made in the form of a number of modules, these modules can be designed so that in combination they bring about an outer contour which essentially follows the contour of the arm. Alternatively, the connecting piece can, whether it is made in the form of one or more modules, be designed without special regard to the aerodynamic contour of the arm and in such a case the connecting piece can advantageously be covered with an aerodynamically shaped cover.
- This aerodynamically shaped cover can either be integrated with one or both of the arm sections or can be made as a loose cover in one or more pieces, which is mounted over the connecting piece.
- the connecting piece In its basic shape, the connecting piece is made so that it has no effect on the overall shape of the arm, but in a variant the connecting piece can be made so that the overall shape of the arm is changed in an appropriate direction which could be inappropriate in the case of an arm in one piece.
- this may be in the form of a change in the longitudinal axis of the arm in the chord direction or in the form of a change in the longitudinal axis in the lift direction, or a combination of these with an angle change about an arbitrary axis.
- a connecting piece according to the invention can be made from metal, for example cast iron or steel, or from a composite material, for example glass-fiber-reinforced epoxy, or from other materials.
- the invention was developed for and has as a strong point use for windmill arms, but the invention is of general nature and can likewise be used for other types of arms.
- Figure 1 shows the positioning of a connecting piece inserted into an arm
- Figure 2 shows a longitudinal section of a connecting piece inserted between two arm sections
- Figure 3 shows a perspective illustration of a connecting piece
- Figure 4 shows a perspective illustration of a connecting piece composed of a number of modules
- Figure 5 shows a connecting piece composed of a number of identical modules
- Figure 6 shows a covering of a connecting piece, which does not have a profiled shape like the arm
- Figure 7 shows an alternative covering of a connecting piece, which does not have a cross-sectional shape like the arm;
- Figure 8 shows an embodiment of a connecting piece which is used to change the overall shape of the arm in the chord direction, and
- Figure 9 shows an embodiment of a connecting piece which is used to change the overall shape of the arm in the lift direction.
- Figure 1 shows the positioning of a connecting piece 1 between two arm sections 2 and 3.
- Figure 2 shows a longitudinal section of an arm assembled according to the invention.
- the connecting piece 1 connects the two arm sections 2 and 3.
- One or more bolts 4 secure the flange 5 of the connecting piece to the arm section 2.
- the means of retaining the bolt in the arm section is shown here as a transverse nut 6, but the bolt can also be embedded firmly in the arm section, and the nut can also be firmly embedded, if appropriate longitudinally, so the thread is concentric with the longitudinal axis of the nut, or the thread can be provided in one or more larger bodies embedded in the arm section.
- the bolt can be provided with a head or can be made in the form of a threaded rod with a nut 7.
- the arm section can advantageously be made with increased material thickness 8 close to the connecting surface.
- the arm section is provided with one or more shear webs 9, these can be made with a cutout 10 which improves access conditions at the connecting piece and reduces the stress concentrations when assembly takes place.
- one or more shear webs can be connected via the connecting piece which connects the arm shells or to one or more separate connecting pieces.
- Figure 3 shows a perspective illustration of a connecting piece 1 which is made with a shape which approximately follows the cross-sectional profile of the arm.
- the connecting piece 1 comprises a pair of flanges 5 for bearing against the two arm sections 2, 3 and a number of holes 11, through which bolts 4 for fastening the arm sections 2, 3 to the connecting piece 1 can be inserted.
- the flanges 5 are interconnected by ribs 12.
- the connecting piece 1 is shown with an inward-facing flange, so the bolts 4 can be tightened and adjusted from inside, but the connecting piece 1 can also be made the other way round, so the bolts 4 can be tightened and adjusted from outside.
- Figure 4 shows a connecting piece 1 according to the invention which is divided into a number of modules 1', for example two modules as on the left-hand side of the figure or a number of modules 1' ' as on the right-hand side of the figure.
- FIG. 5a shows an assembly according to the invention in which use is made of a larger number of modules 1' ' , shown here as they would be mounted next to one another for the connection of two arm sections.
- Each module 1' ' consists here of two flanges 5, two ribs 12 and an outer part 13.
- all the modules 1' ' can advantageously be identical, but they do not have to be so. Different embodiments are therefore shown in Figures 5b, 5c and 5d.
- the module in Figure 5b has two flanges 5, one rib 12 and an outer part 13
- the module in Figure 5c has two flanges 5 and two ribs 12
- the module in Figure 5d has two flanges 5, two ribs 12 and an outer part 13.
- Figure 6 shows an assembly according to the invention in which use is made of a connecting piece 1 in an embodiment which is not shaped approximately like the cross-sectional profile of the arm sections 2, 3.
- the connecting piece 1 is therefore covered by a cover 14, which is fastened to one or both of the arm sections 2 and 3.
- the cover 14 can also be fastened to the connecting piece 1 and can be in one or more pieces .
- Figure 7 also shows an assembly according to the invention in which use is made of a connecting piece 1 in an embodiment which is not shaped approximately like the cross-sectional profile of the arm sections.
- the connecting piece 1 is therefore covered by a cover 15 which is made as an integrated part of one or both of the arm sections 2 and 3.
- Figure 8 shows an assembly according to the invention in which the connecting piece is used in order to change the overall shape of the arm in the chord direction.
- the connecting piece 1 between the two arm sections 2 and 3 is made with end surfaces 16 and 17 which have a relative alignment which results in the longitudinal axes 18 and 19 of the two joined-together sections forming an angle 20 which is not 0.
- Figure 9 shows an assembly according to the invention in which the connecting piece is used in order to change the overall shape of the arm in a direction at right angles to the chord direction.
- the connecting piece 1 between the two arm sections 2 and 3 is made with end surfaces 16 and 17 which are not parallel, which results in the longitudinal axes 18 and 19 of the two joined-together sections forming an angle 20 which is not 0.
