Definitions

  • the present invention describes a combined lifting beam arrangement for handling wind turbine parts, in particular to a combined lifting beam arrangement for handling tower wall portions and a nacelle and/or a hub and/or a generator of a wind turbine without changing the lifting beam arrangement between two lifting operations.
  • the present invention further describes a method of handling different wind turbine parts using the same combined lifting beam arrangement.
  • Such a device is disclosed in document EP 2364949 A1 .
  • wind turbines are constructed as hollow steel towers made of prefabricated tower portions.
  • the tower is constructed or assembled by successively lifting and placing a series of tower wall portions on top of each other, whereby the lowest tower wall portion is mounted on a foundation, usually made of concrete, and includes access means such as a doorway to later allow access for a maintenance crew.
  • the tower wall portions become successively smaller in diameter towards the top of the tower.
  • Neighbouring tower wall portions are connected by means of fasteners such as construction bolts inserted into connection holes in the end flanges.
  • connection holes of the neighbouring portions are positioned such that connection holes in the top flange of the lower tower wall portion match the connection holes in the bottom flange of the upper tower wall portion.
  • a number of lifting fittings usually at least two - is mounted to one of the end flanges of the portion, usually the upper flange, and a cable is connected to the lifting fittings to allow a crane to hoist the portion onto the previously assembled partial tower wall portion.
  • the successive tower wall portions generally differ in diameter owing to the overall conical tower shape, and the spacings between the connection holes therefore also differ.
  • prior art lifting techniques have required multiple lifting fittings, sometimes even a specific lifting fitting for each tower section.
  • a lifting technique for the installation of a nacelle, hub and generator at the top of a wind turbine tower are also known in the art.
  • individual lifting brackets or sling systems are used for handling these wind turbine parts.
  • a special sling system is connected to a nacelle or hub or generator to lift it into the position at the top of the tower, wherein the sling system comprises a number of slings for holding the nacelle or the hub or the generator at special coupling means.
  • the object of the invention is achieved by the combined lifting beam arrangement according to claim 1, and by the method of handling wind turbine parts according to claim 10.
  • the combined lifting beam arrangement according to the invention is specifically adjusted for handling wind turbine parts, in particular wind turbine parts having different engaging structures, such as tower wall parts, nacelles, hubs, or generators of a wind turbine.
  • the combined lifting beam arrangement comprises a beam with a connecting element.
  • the connecting element is realized to be connected to the lifting device directly or via a coupling element such as a hook liftable by the lifting device.
  • the beam may be connectable to the lifting device by means of the connecting element, such as a pad eye, a loop, a grommet or the like.
  • the beam may be connectable to the connecting element in a detachable manner, for example for facilitating the transport, maintenance work of the lifting beam arrangement or the like.
  • the lifting beam arrangement further comprises a first interface for a first engaging structure and a second interface for a second engaging structure which are provided at the beam, preferably at different positions so that they cannot interfere with each other.
  • additional interfaces for a third or fourth or even more engaging structures may be present at the beam without deviating from the invention.
  • Interface means in the sense of the present invention, any connecting means adapted to a specific engaging structure of a wind turbine part such as of the tower wall portions, the nacelle, the hub, the generator or the like.
  • engaging structure means that the element to be lifted has a portion into which a holding member of the interface can be engaged by means of a structural engagement, e.g.
  • the first interface has a number of first holding members adapted for an engagement of the lifting beam arrangement with a tower wall portion of a wind turbine and the second interface has a number of second holding members adapted for an engagement of the lifting beam arrangement with coupling elements of a nacelle and/or a hub and/or a generator of a wind turbine.
  • a "holding member” can be any member suitable for holding the respective wind turbine part with a specific engaging structure such as a holding tool having a corresponding structural configuration.
  • the first and second holding members may comprise portions for locking the first and/or second holding members at the beam.
  • they can be locked at the beam in a releasable manner in one preferred position or may be slidable at the beam along its longitudinal direction.
  • an adaptation of the position of the first holding members to different diameters of the tower wall portions or of the second holding members to the geometry of the other wind turbine parts is possible.
  • one or more bolts may be provided which may be inserted into one or more holes in the first holding member and/or in the second holding member and/or in the beam.
  • the first and/or the second holding members may be integrally provided in the beam.
  • the above-described combined lifting beam arrangement may be used in the method according to the invention.
  • the method according to the invention is particularly straightforward and fast. Since no individual slings and lifting brackets are used for handling of wind turbine parts having different engaging structures and the same combined lifting beam arrangement is used for handling the tower wall portions and the nacelle and/or the hub and/or the generator, the main lifting device, e.g. a crane, can go directly from the tower top to the nacelle after transferring or installing the top tower wall portion. "Transferring" in the sense of the invention means any handling procedure used during installation, transportation or loading of wind turbine parts. Therefore, the method according to the invention reduces not only crane time and human resources needed for handling operations of wind turbine parts, but also reduces the overall costs.
  • the combined lifting beam arrangement according to the invention may preferably be constructed to handle wind turbine parts having different engaging structures, such as tower wall portions with different diameters or a nacelle or hub or generator of a wind turbine.
  • the beam of the combined lifting beam arrangement may have an elongated shape being extendable in its longitudinal direction.
  • the beam may for example be manufactured from a rigid material such as a metal, in particular iron or steel.
  • the beam may also be represented by a bar, a rod, a pole or the like.
  • the length of the beam (along its longitudinal direction) may range between about 2 m and 20 m, in particular between about 4 m and 10 m, more preferably between about 5 and 8 m.
  • the length of the beam may depend on the diameter or the length of the parts of a wind turbine to be lifted with the same lifting beam arrangement such as a tower wall portion, a nacelle or the like.
  • the length of the beam may be larger than the diameter of the largest tower wall portion and/or the length of the other parts to be lifted.
  • the beam may have a specific cross-sectional shape for providing a sufficient stiffness to withstand forces acting on the holding members and being transferred to the beam, when the tower wall portion and/or the other parts of a wind turbine such as the nacelle, the hub, or the generator are engaged by the interfaces.
  • the beam may have a cross-sectional shape such as a T-shape, H-shape, I-shape, U-shape, O-shape or any other shape providing a sufficient stiffness for holding and lifting a wind turbine part such as a tower wall portion or a nacelle or the like.
  • the first interface comprises an automatic hook system.
  • An automatic hook system may have a number of (in particular 2, 3, 4 or even more) locking elements for locking the tower wall portions at different positions.
  • An example of such a locking element is a grabbing element or a claw which can grab the top flange of a tower portion at different positions, in particular at two opposite positions at the inner perimeter of the tower top flange.
  • the first interface in particular the automatic hook system of the first interface, may further comprise a manually or automatically driven actuator moving at least one of the holding members.
  • actuators are hydraulic or pneumatic or electrical actuators like a piston, a motor, a magnetic valve, or the like. Those actuators may be driven by a battery or a fuel-driven generator.
  • the actuator is a remote controlled (for example by means of radio frequency) actuator which can be controlled from a site different from the place of the actuator.
  • the remote control may be handled from any position suitable to control the installation of a wind turbine, for example from the ground, a ship, a crane or the like.
  • Such an actuator may for example bring locking elements of an automatic hook system in engagement with the tower wall portion at a specific engagement position.
  • at least one of the first holding members comprises a locking element adapted for engaging with an engaging structure of a tower wall portion.
  • the locking elements are adapted for engaging with a flange arranged at an end, e.g. the top, of a tower wall portion during the handling operation.
  • the locking elements may be mechanically displaced from one inner position to one outer position, e.g. by activating two or more joined rods by an actuating means.
  • the locking elements are positioned behind at least a part of a bracket of an end part of a tower wall portion or a rim or a flange protruding from the tower wall portion inwards.
  • the locking elements and thereby the combined lifting beam arrangement may be locked or secured to the tower wall portion from falling down.
  • the locking of the tower wall portion to the first holding member may be stably achieved by increasing the distance between the locking elements, involving clamping radial outer portions of the locking elements between inner surfaces of the tower wall portion.
  • the second holding member comprises a number of, preferably essentially vertical, wires which can be used for handling and lifting a nacelle or a hub or a generator.
  • wires other flexible lifting means such as, e.g., slings, ropes, chains, or more stiff lifting means such as, e.g. plates, beams or frames, can be used.
  • stiff lifting means may be useful to withstand the weight or the structure of the turbine part.
  • frames or plates they can be combined with more flexible lifting means to provide a second holding member adjusted to a specific part of a wind turbine.
  • a frame for a nacelle, hub or generator made of a rigid material can be connected by means of a chain or a sling to the beam.
  • the holding members such as slings or wires are positioned such that they are in a nearly vertical position during operation, that means that the coupling means of the wind turbine part and the holding member connection with the combined lifting beam arrangement are vertically aligned
  • the forces in the lifting points i.e. the coupling means
  • the both ends of the slings are positioned at the beam in a position that each of the ends will be essentially vertical, i.e. up to an angle of about 1 to 15 degree, preferably between about 2 to 10 degree, more preferably between about 4 to 8 degree, especially about 6 degree.
  • connection points with the beam depends thus on the width of or the distance of the coupling means at the nacelle or other wind turbine parts to be lifted. Therefore, it is preferable that the second holding members may be movably connected to the beam so that the distance between two or three connection points at the beam can be manually or automatically varied.
  • a further advantage of vertical second holding members e.g. vertical slings, is that less force is applied to the lifting points and thus smaller slings can be used, for example slings made of wires with a smaller diameter than conventional wires. Hence, this would reduce the amount of material and thus lowers the costs and the weight of the second holding members and the whole combined lifting beam arrangement. Moreover, smaller and vertical slings may be easier to handle for the technicians.
  • the inventive combined lifting beam arrangement according to the invention may have one or two control line coupling means for connecting control lines for rotating the lifting beam arrangement and the wind turbine part hanging thereon.
  • the control lines are attached to the lifting beam arrangement and not to the tower wall portion, nacelle, hub or generator, the wind turbine parts can be freely rotated during the handling operation.
  • the combined lifting beam arrangement further may be designed to have a pitch system for adjusting a pitch of the beam from a horizontal position into a position angular to the horizontal position, preferably during operation of the lifting beam arrangement.
  • the pitch is the deviation of the main horizontal axis of the beam from the horizontal position. If the beam and the main horizontal axis of the lifted wind turbine part are nearly in a parallel position, the pitch may also be the deviation of the main axis of the wind turbine part from the horizontal position.
  • the pitch system preferably comprises at least two pitch system connecting members connecting the pitch system with the beam at two or more different coupling positions in a longitudinal direction of the beam.
  • the pitch system connecting members comprise two or more wires connecting the lifting device (e.g. a hook of a crane) with two or more different coupling positions at the beam for holding the beam in a working position.
  • the working position is generally horizontal in its basic modus, while the beam may be in a pitch modus by changing the length of at least one of the wires.
  • the wires i.e. of the pitch system connecting members
  • one, two or more of the wires may be provided with a winch to adjust the pitch (that means the angle between the beam and the horizontal position) of the lifting beam arrangement.
  • the winches are provided movable in longitudinal direction at the beam.
  • the pitch of the lifting beam arrangement may be adjusted by moving the position of one or more of at least two coupling positions at which at least two pitch system connecting wires are provided for connecting the pitch system with the beam in a longitudinal direction of the beam. If, for example, moving the position of one of the coupling positions to a different position nearer to the end of the beam the leverage force on the beam is changed.
  • the pitch of the wind turbine parts lifted can be changed by individually changing the length of the first and second holding members connecting the beam with the wind turbine part lifted. This change of the length can also be made by means of winches provided in the first or second holding members.
  • the first interface comprises parts of the second interface and/or the second interface comprises parts of the first interface.
  • the holding members of the first interface can be used together with or instead of some of the holding members of the second interface.
  • the slings for nacelle or generator lifting can be used as additional holding members during the handling or installation of the tower wall portions.
  • the tower wall portion can be supported by the second holding members. That means, e.g., the wires can be locked into separate coupling elements at the outside of the tower wall portion in order to stabilize the position of the tower wall portion during installation.
  • the wires constituting the second holding members may be used as control lines during the tower installation instead of separate control lines or together with separate control lines provided at the combined lifting beam arrangement.
  • the combined lifting beam arrangement comprises a remote control system realized to control parts of the first and/or the second interface.
  • a remote control system realized to control parts of the first and/or the second interface.
  • the remote controlled locking and releasing of the interfaces, in particular the holding members reduces installation time because the technician does not need to change the position and, in particular, the right surveillance eliminates the demand for having technicians in the tower when hooking on and off the tower. This will also allow the lifting apparatus such as the main crane, to be released faster to grab the nacelle, the hub or the generator.
  • the above described combined lifting beam arrangement may advantageously be used in the method of handling wind turbine parts according to the invention because it is specifically adapted for tower wall portion lifting and nacelle lifting and, optionally, hub or generator lifting.
  • a change of the lifting beams during the installation of a wind turbine is not necessary and the main crane can start nacelle installation subsequently after having installed the top of the wind turbine tower portions.
  • the time for installation can be significantly reduced with this combined lifting beam arrangement.
  • At least one of the engaging and/or transferring steps is controlled by remote control.
  • an automatic hook system is used for hooking on and off the tower wall portions. Then, the crane may go directly to hook on the nacelle without any change in the lifting beam arrangement after installation of the tower wall portions.
  • the second holding members are then engaged into the respective engaging structures to lift the nacelle.
  • an automatic system is used with the second holding members. Then, the first and the second interfaces can be remote controlled from a position outside the tower, for example on the ground or in a crane. If, for example, the first and/or the second interface is controlled by remote control mechanisms, installation time can be significantly decreased and the installation procedure can be made safer because it is not demanded that a technician need to climb up and down the tower to disengage the wind turbine parts.
  • a pitch control step for adjusting a pitch of a beam of the lifting beam arrangement from a horizontal position into a position angular to the horizontal position comprises changing the length of one of at least two pitch system connecting members connecting the pitch system with the beam at two or more different coupling positions in a longitudinal direction of the beam.
  • the working position of the lifting beam arrangement is generally horizontal in a basic modus.
  • the beam may be in a pitch modus by changing the length of at least one of the pitch system connecting members such as wires connecting the beam with the connecting element provided for connecting the lifting beam arrangement with a lifting device.
  • the length of the wires i.e. of the pitch system connecting members
  • one, two or more of the wires may be provided with a winch to adjust the pitch (that means the angle between the beam and the horizontal position) of the lifting beam arrangement.
  • the control step comprises moving the position of one or more of at least two coupling positions at which at least two pitch system connecting wires are provided for connecting the pitch system with the beam in a longitudinal direction of the beam.
  • the winches are provided movable in longitudinal direction at the beam.
  • the pitch of the lifting beam arrangement may be adjusted by moving the position of one or more of at least two coupling positions at which at least two pitch system connecting wires are provided for connecting the pitch system with the beam in a longitudinal direction of the beam. If, for example, moving the position of one of the coupling positions to a different position nearer to the end of the beam the leverage force on the beam is changed and a desired pitch can be foreseen.
