Definitions
- This invention relates to a method for producing a rotor blade of a wind energy plant and to a production facility for producing a rotor blade of a wind energy plant.
- the rotor blades of a wind energy plant consists of different elements or semi-finished products. These can for example consist of bars or bars. These are inserted into the rotor blade at different times during the manufacturing process.
- the object of the invention is now to improve the rotor blade production as a whole, to reduce the costs for this, to enable a more rapid and safer sheet production and to allow overall faster rotor blade production and at the same time to improve the safety of the sheet production.
- German Patent and Trademark Office has in the priority application for the present application the following state of the art research: DE 42 26 397 A1, DE 102 08 850 A1, DE 10 2007 033 414 A1, EP 2 226 186 A1, Magazine: Windblatt 03/12 Fa. ENERCON, page 1 - 20, brochure: MDS Griffinsysteme 06/2012, p. 1 - 28.
- the object is achieved with a method according to claim 1 and a production device according to claim 6.
- Advantageous developments are described in the subclaims.
- the semi-finished product is produced parallel to the rotor blade and in one and the same building, but on different building levels, so for example, the rotor blades on the ground floor of the building while the semi-finished product is produced on the upper floor and the semifinished product on the upper floor can be lowered down through openings between the upper and lower levels into the ground floor.
- the advantage of this method is that the production can be very compact and thus the production building can have a smaller footprint than before.
- the parts that are produced in the upper floor level transported by means of a crane or cable etc. from the upper floor level in the ground floor level and thus merged with the parts produced in the ground floor level of the rotor blade.
- a load lifting device such as a crane, cable, winches in general, arranged a chain hoist, a mast and / or lifting portal in the two-storey manufacturing building.
- a first crane e.g. a gantry crane
- a second crane e.g. Portal crane
- the carrying capacity of the first crane or rope is less than the carrying capacity of the second crane or rope.
- the first crane or the first rope so the crane in the upper floor level, has a lower load capacity, since the parts that are made in the upper floor level, have a lower weight than the rotor blade itself.
- a semifinished product is understood to be a partial element which is incorporated in the rotor blade, that is, laminated. This can be, for example, the spar or web of the rotor blade.
- the first or second crane can be, for example, a gantry crane. This spans his work area like a portal and can therefore lift or carry very high loads.
- the maximum crane load in the ground floor level ranges from 30 t to 40 t, while the crane's maximum crane load in the upper floor level ranges between 1 t and 10 t, preferably 5 t, lies.
- the crane load corresponds to the load that the crane can carry or transport, ie the load capacity of the crane.
- an opening is provided between the upper floor level and the ground floor level in the floor of the upper floor or in the ceiling of the ground floor through which the parts produced in the upper floor level can be lowered into the ground floor level ,
- this opening can be closed, for example, by means of a plate embedded in the floor of the first floor level and / or in the ceiling of the ground floor level, which can be moved by a motor.
- the semi-finished product produced in the upper floor level can be transported in a simple and especially direct manner in the ground floor level.
- the semifinished product provided for a specific rotor blade can be lowered directly to the correct position to the rotor blade with a corresponding arrangement of the opening.
- long and time-consuming transport routes are avoided within the production building.
- FIG. 1 shows a process sequence for manufacturing a rotor blade of a wind energy plant
- FIG. 2 shows a production according to the invention
- Fig. 6 two lattice binder.
- Fig. 1 illustrates the general course of a rotor blade production.
- the half-shell in which the halves of the rotor blade are made, covered with glass fiber mats.
- the semi-finished product is already inserted into the glass fiber mats.
- both shells are covered and cured with resin, they are glued to form a rotor blade.
- the assembly takes place. This term covers, for example, the machining of the flange, the testing of lightning protection, etc. In the finish area, the rotor blade is painted and all the necessary preparatory steps are processed for this purpose.
- the rotor blade After the rotor blade has been painted and all necessary preparation steps have been completed, the rotor blade is directly in the production building, for example attached to a truck for delivery. Thus, the entire rotor blade production takes place up to the preparation of the delivery within a production building.
- Fig. 2 and Fig. 3 illustrate the production process of blank production for a rotor blade of a wind turbine.
- the individual production processes are arranged one after the other.
- a half-shell 1 1 and 12 are produced, which are merged after the gluing process.
- the belt is introduced by means of the gantry crane 21 in the half-shells.
- the half shells are moved to the next station, process step 2. Since the space of station 1 is now free, the form is moved from empty space 4 to station 1 and can thus be reassigned.
- the molds In order for the molds to move from one station to the next station, they are mounted on a shuttle car.
- the shuttle is shown in FIG. In this illustration, only the substructure of the carriage is shown. The carriage is moved on rails 13.
- the scrim is soaked in resin. This is the process step 2 of the infusion.
- a vacuum infusion process is used.
- the fiber composite Once the fiber composite has been soaked in resin, it must be heat treated for the resin to react. This process is called annealing.
- Annealing 3 is performed on a separate station. When changing the station from station 2 to station 3, the mold must be kept under vacuum.
- each rotor blade has an energy unit and a vacuum unit, which maintains the vacuum on the mold when moving.
- the webs are applied to the half-shells and glued. Then both half-shells are folded onto each other and glued together, process step 6. This is done with the help of a gluing portal. After bonding, the superimposed half-shells are annealed again. After completion of annealing, the rotor blade can be removed from the formwork, process step 7. For this purpose, the upper formwork is removed by means of a lever device of the lower formwork. The rotor blade is then moved on to the empty space 4, from where it is brought into the clothing. The empty form is then available again for the next rotor blade.
- the production facility is divided into two levels (storeys), namely the ground floor level 26 and the upper floor level 23.
- the rotor blades or essential parts thereof are manufactured and also assembled.
- the upper level (upper floor) 23 semi-finished for the rotor blades is made. All necessary production facilities, such as trimming equipment, molds, etc. for the semi-finished product, including a crane (gantry crane), are located on the upper floor, ie on the upper level.
- the blank for the glass fiber mats for the semi-finished product is located on this second, ie the upper level (upper floor).
- Semi-finished product of a rotor blade is / are, for example, the belt or the webs and other laid in the rotor blade parts. The belt is produced, for example, in a first production process, the webs in another production process on the upper floor.
- the invention not only saves considerable (up to 20% or more) of the surface area of the production facility, so that in total also less base area must be sealed, but the production cycle time can be significantly increased, for.
- the entire production process becomes safer and the production quality significantly better, because no longer in operation Always and constantly in a plane large and heavy parts must be transported by means of gantry cranes over the heads of people away, so that the safety at work is significantly improved.
- the entire production process can thus be made considerably more fluid by means of a corresponding clocking.
- the gantry cranes 21 and 24 transport both parts in the upper floor level as well as parts in the basement level, at least in the area where between the upper floor level and the basement level is an opening.
- a separate gantry crane which has a lower maximum load, e.g. up to about 5 t, has as a gantry crane in the ground floor level.
- the production run time is significantly shortened, e.g. by more than 30% compared to a standard production where all major production steps take place on one level, ie in a single large hall.
- the carriage 25 is shown schematically in Fig. 5 in a plan view.
- a longitudinal direction 1 1 1 with a double arrow and a transverse direction 121 is also shown with a double arrow for illustration.
- the longitudinal direction 1 1 1 and the transverse direction 121 are arranged substantially perpendicular to each other. It does not depend on an exact angle of 90 degrees between these two directions 1 1 1 and 121, but they should not be parallel to each other.
- FIG. 5 it can be seen that 16 part-changing devices 125 are provided, which together form the changing device 124.
- Each partial change device 125 is assigned a pair of wheels 122.
- Two partial change devices 125 are fastened to longitudinal members 134 together with a connection carrier 132.
- a common lowering of the wheel pairs 122 by the part changing devices 125 and thus by the Changing device 124 thereby leads to a lifting of Verfahrwagens 25, in particular on these side members 134.
- On the side rails 134 is a plurality of cross members 136 arranged or the side members 134 and cross member 136 are connected to a stable structure of the carriage 25.
- various longitudinally arranged support beams 138 are provided.
- the longitudinal members 134, cross members 136 and support beams 138 which in each case need not be identical, although only one reference numeral is used here, essentially form the carriage 25, at least its stable support structure.
- transverse drives 126 For driving the pairs of wheels 122, some transverse drives 126 are provided, which also have a gear 128.
- the coupling to the respective wheel pair 122 can not be seen in the overview representation of FIG. 5.
- the transverse drives 126 are in each case mechanically mutually independent gearboxes, which are, however, electrically coupled or synchronized in order to achieve the most uniform and equal movement of the carriage 25 during a movement in the transverse direction 121. In this case, not all pairs of wheels 122 of the second set of wheels 120 are driven.
- a hydraulic unit 140 is provided, which is provided for actuating the changing device 124 and thus the individual part changing devices 125.
- FIG. 6 shows two lattice binders 50, 51 of two rotor blade forms for producing one rotor blade half shell each.
- the lattice binders 50, 51 each have substantially a lattice construction 52, 53 in order to each carry thereon a shaping layer in which heating elements are embedded.
- This shaping layer may be connected to further layers in a sandwich structure.
- This shaping layer is not shown for clarity in the figure 6, so that the shape of each trellis 50, 51 and thus the grid structures 52, 53 can be seen better.
- To supply the heating elements with electric current for heating a plurality of supply units 55 are provided for each rotor blade.
- the supply units may differ in detail. Nevertheless, the same reference numerals for the supply units are used to improve the clarity.
- Each supply unit 55 each supplies a heating area with electric current and controls the respective supply current accordingly. Furthermore, in each case a central control 56 is provided in order to supply the relevant supply units 55 with switching commands. At the central control unit 56, the entire control of the respective rotor blade shape is coordinated and processes and conditions, in particular temperatures can be displayed. The central control unit 56 can also be used for manual intervention.
- the supply units 55 are supplied with power via busbars. Furthermore, the busbars serve for data transmission between the supply units 55 and the central control units 56. A separate power bus and a separate data bus may be provided.
- the supply units 55 and central control units 56 are arranged within the grid structures 52, 53.
- connection carrier 134.
- Side member 136.
- Cross member 138.
