    has a substantially vertical direction (horizontal direction for the constituent blades) to a position where the propeller shaft has a substantially horizontal direction (where the blades have a substantially vertical direction). If the lifting unit consists of an assembled propeller, propeller shaft and generator, the unit may need to be positioned in the direction of your shafts and around your shafts at the same time when attaching to the nacelle. Known constructions lack positioning possibility in corresponding axial directions as is possible with that construction according to the present invention.
    There is a need for a device and method with which components for a wind turbine can more easily and efficiently be lifted up to the top of the site and positioned below the surface.
    Prior art Structures which are intended to be used for lifting components to the top of the tower in a wind turbine are already known. For example, patent specification US2009282776 describes a lifting device which is intended to move components to the top of the tower in a wind turbine. The construction differs greatly from the construction in accordance with the present patent application. For example, it is not possible with the construction to lift a propeller and during the lift reposition the propeller between a horizontal direction to a vertical direction.
    Patent specification EP1 101934 describes a lifting device for components for a wind turbine.
    The construction differs from the construction according to the present patent application.
    For example, the construction does not comprise a lifting device which during the lifting is intended to be able to be moved in the vertical longitudinal direction of the tom.
    Patents DE19741998 and DE1967515 describe a lifting device which can be moved in the vertical direction after the tower of a wind turbine. The construction differs substantially in scope from the present patent application. The constructions according to the patents are not, for example, arranged to be able to rotate the lift about a substantially horizontal axis. A propeller with associated hubs can therefore not be lifted in a corresponding manner as with the lifting and positioning equipment according to the present patent application.
    International patent application WO2007097640 describes a device with which components can be moved after the tower of a wind turbine in the vertical direction. The construction differs significantly from the construction according to the present patent application.
    WO2009056701 describes a lifting device with which a propeller can be moved and lifted to the top of an empty wind turbine. The construction differs significantly from the construction according to the present patent application. For example, the construction according to the patent specification does not include a function with which the above-mentioned constructions are, however, conditioned by a number of shortcomings and shortcomings.
    For example, these structures lack a positioning function with which, for example, a unit comprising assembled propeller (with propeller blades mounted) and propeller shaft and generator, can be lifted up to the top of the tom and operated from a position where the propeller shaft is substantially vertically directed to a position where the propeller shaft axis is substantially horizontal directed. Furthermore, there is a need to be able to rotate what is to be lifted around the center axis of the tower, i.e. vertical direction. OBJECTS OF THE INVENTION The main object of the present invention is to provide an improved lifting and positioning device with which components can be lifted after the tower of a wind turbine and respectively position the lift in the top of the empty space. A further object of the present invention is to create a lifting device which can be moved from one wind turbine tower to another wind turbine body. It is a further object of the present invention to create a lifting device whose support means are positionable according to the diameter of the tom.

    Figures 7 to 12 show in a sequence an example of how a component can be lifted and positioned.
    Referring to the figures, there is shown a lifting (pre-moving) and positioning device 1 in accordance with the present invention. The lifting and positioning device 1 is preferably intended to be temporarily connected to the site 2 by a wind turbine.
    The lifting and positioning device 1 is intended to be used to surface at least one object 3, such as for instance one or fl your components, objects or the like, in the axial direction of a wind turbine toms 2. Preferably, the lifting and positioning device is intended to lift components up or down from the nacelle 4 at the top of the wind turbine tower 2. The lifting and positioning device includes functions for positioning the lifting object 3, the object or the like during lifting, assembly, disassembly or other situations. where a positioning (position change) of the lifted object needs to take place.
    The lifting device 1 comprises at least one frame 5, at least one positioning device 6, at least one supporting device 7, and at least one for moving device 8.
    The frame 5 is intended to enclose or substantially enclose the circumference of the tom 2. The body 5 preferably consists of at least a first body part 9 and at least a second body part 10. The first body part 9 and the second body part 10 are mounted together with at least one first interconnecting member 11. Preferably the first body part 9 and the second body part 10 are connected together with at least a first interconnecting member 11 and at least one second interconnecting member 12. In the figure, the first interconnecting member 11 consists of at least one or more screw connections. The second interconnecting member 12 in the figure consists of at least one or more screw connections. It is conceivable that the interconnecting bodies consist of other interconnecting means suitable for the purpose. For example, the interconnecting members may be a shaft or the like which runs through one or more of the holes in the first body part and holes in the second body part.
    The positioning device 6 is intended to be connected to the frame 5. The positioning device comprises at least one operating arm 13. The operating arm in the preferred embodiment comprises at least a first arm part 14 and at least a second arm part 15. The operating arm 13 is for example intended to be used to change position and position the lifted object relative the frame 5, the tower 3 and the nacelle 4. Examples of these position changes, of the lifted object, which are made possible with the positioning device are shown in the grooves 7 ~ 12. Preferably the operating arm 6 is connected to the frame 5 via at least one arm bracket 16. The arm bracket 16 includes in the exemplary embodiment at least one T-shaped part which is stored via at least one bearing 17 arranged in a corresponding T-shaped groove in the body. In alternative embodiments, the T-shaped part and the T-shaped groove, respectively, may be of a different type suitable for the purpose.
    The control arm 13 is rotatably arranged via the construction in relation to the center of rotation of the frame 5 and the axial center of the tower. The armrest 16 can be rotatable along all or parts of the circumference of the frame 5. In the exemplary embodiment, the arm bracket 16 is rotatable according to parts of the circumference of the frame 5. The rotatability is achieved via at least one bearing 17 and preferably with a number of bearings 17. The respective bearing 17 can consist of a sliding bearing 18, a ball bearing 19, a roller bearing 20 or of another bearing suitable for the purpose. The bearing 17 can also consist of a combination of specified bearings. Through the bearing 17, the arm bracket 16 with associated operating arm 13 is rotatably arranged around the center of rotation (vertical axis) of the tower 2.
    In the exemplary embodiment, the arm bracket 16 comprises at least one first shaft pin 21 and at least one second shaft pin 22 to which the operating arm 13 is mounted mounted. The first arm part 14 of the actuator 13 is connected to the first shaft pin 21. The second arm part 15 of the control arm 6 is connected to the second shaft pin 22. The connection to the shaft pins 21 and 22 takes place with prior art, so this is not described in more detail in this patent application. In alternative embodiments, it is conceivable for the operating arm 13 to be connected to the body 5 by another technique suitable for the purpose and already known in the art.
    The operating arm 13 is in the embodiment rotatably arranged about a first axis of rotation 23 which substantially coincides with the axial center of the first shaft journal 21 and the second shaft journal 22 (center line e). The axis of rotation 23 is preferably substantially horizontally directed. The axis of rotation 23 is further preferably substantially tangentially directed relative to the tower. In alternative embodiments, the axis of rotation 23 may be of a direction which deviates substantially from a substantially horizontal direction. In alternative embodiments, it is conceivable that the axis of rotation 23 may have a different direction which deviates substantially from a substantially tangential direction.
    A rotation between the object 3 and the control arm 13 can also take place via at least a second axis of rotation 24. The rotation of the object about the axis of rotation 24 can take place by means of at least one hydraulic motor (not shown in figures) or the like.
    In alternative embodiments, it is conceivable that the arm bracket 16 is made rotatable about a substantially horizontal center of rotation which is substantially radially directed relative to the center of rotation of the tom.
    The control arm 13 can also be rotatably arranged around the longitudinal direction of the control arm.
    The construction comprises at least one supporting device 7 with which the lifting and positioning device 1 is supported against parts of the mantle surface of the tower. The support device 7 preferably comprises at least three support means 25 which support and position the lifting device relative to the tower 2 of the wind turbine. In the exemplary embodiment shown in the figures, the lifting and positioning device 1 comprises four support means 25 of which three support means are shown in the figures. The positions of the support members 25 are adjustably (operably) arranged in radial direction relative to the axial direction of the tower 4. The actuation of the respective support means 25 preferably takes place in a substantially radial direction in relation to the axial direction of the tower 4.
    Alternatively, the operation of the support means 25 in relation to the axial direction of the tower may deviate substantially from a substantially radial direction.
    Figures 5A and SB show how the maneuvering of the position of the respective support members in relation to the tower (the mantle surface of the tom and the axial center of the tower) can take place with at least one adjusting member 26.
    Figure 5B shows how the adjusting member 26 can be constituted by at least a first adjusting body 27 and at least a second adjusting body 28. The first adjusting body 27 and the second adjusting body 28, respectively, are wedge-shaped in the embodiment shown in Figure 5B. The first wedge-shaped adjusting body 27 and the second wedge-shaped adjusting body 28 are arranged to be actuated with each other. The actuation of the wedge-shaped adjusting bodies 27 and 28 is mutually achieved by at least one of the wedge-shaped adjusting bodies 27 and 28 being movably arranged relative to the second adjusting body 27 or 28. Preferably the second adjusting body 28 is movably arranged relative to the first adjusting body 27. The actuation of the second adjusting cup 28 relative to the first adjusting body 27 takes place, for example, with at least one ball screw 29 or the like. By selecting the mutual direction of movement, between the first adjusting body 28 and the second adjusting body 28, an adjustment of the position of the supporting device can take place in relation to changes in the diameter or dimension of the tower (2). When the adjusting body 28 is moved relative to the adjusting body 27 in one direction, the distance between the supporting member and the axial center of the tower 2 (respectively the mantle surface) is reduced. During a movement of the adjusting body 28 in the other direction, relative to the adjusting body 27, the distance between the supporting member and the axial center 2 of the tower (respectively the mantle surface of the tower) increases.
    Figure 5A shows in an alternative embodiment that the adjusting member 26 may be constituted by at least one hydraulic cylinder 30, or by another pressure cylinder or device suitable for the purpose, with which the support member position can be adjusted relative to the axial center (respective mantle surface) of the frame and tower respectively. In embodiments where hydraulic components are used, the lifting and positioning device preferably comprises at least one hydraulic pump, hydraulic tank and other components required to drive the hydraulic components such as hydraulic cylinder, hydraulic motor or the like (these are not shown in the figures). Alternatively, the hydraulic components can be driven via at least one hydraulic hose connected to the hydraulic pump and hydraulic tank located in a different place than mounted to the lifting and positioning device 1. It is conceivable that the adjusting means consists of at least one electric motor.
    In the figures, the support means 25 are exemplified by wheels 31. In alternative embodiments, it is conceivable that support means 25 consist of belts 32, belt racks or other support means 25 suitable for the purpose. In cases where the support means 25 consist of support wheels 31, or the like, the wheels are preferably 31 divided into at least a first set of support wheels 33 located at a distance, in the axial direction of the body, from at least a second set of support wheels 34.
    The därför gures therefore show a first set of support wheels (support member) 33 which are placed at a distance, in the axial direction of the void, relative to a second set of support wheels 34. The distance between the first set of support wheels 33 and the second set 34 supporting wheels may vary within the scope of the present invention.
    The lifting device 1 is operated in the axial direction of the empty space with at least one pre-surface device 8. The surface device 8 may consist of at least one first winch 35 with which at least one wire 36 is operated. The winch 35 causes the wire 36, or the like, to be wound up respectively by a drum or the like included in the winch 35.
    Figures 6A to 6C show that the wire 36 is connected at one end to the winch 35. The other end of the wire is fastened in at least one bracket 37. The bracket 37 can be placed in the top of the tower 2, such as for example to at least one bracket 37 in the nacelle 4 In alternative embodiments, it is conceivable for the Winch 35 to be placed at the top of the tower 2 as in the nacelle 4. It is further conceivable for the Winch 33 to be placed on the ground, connected to the foundation of the tower or the like, as shown in Figure 6C.
    In alternative embodiments, the wire may extend over at least one lens pulley 38, break wheels or the like.
    The lens disk 38 is preferably stored arranged in the nacelle 4 or in another suitable place in the top of the tower 3. The figure shows an alternative drying form where the winch 35 is mounted to the frame 5 and that the wire 36 is pulled via at least one lens disc 38, breaking disc or the like in the nacelle 3 and then down to a bracket 37 in the frame 5.
    The lifting and positioning device 1 comprises a function with which the control arm position in relation to the center of rotation 23 is operated. The control arm is rotated relative to the center of rotation 23, for example with at least one hydraulic motor (not shown in the figures) which rotates the control arm 13 about the center of rotation 23.
    In alternative embodiments, the actuation of the actuator 13 can be effected by means of at least one second winch (not shown in figures) with at least one associated wire 39 or the like. The second winch is intended to be used to operate the relative position of the control arm 13 and the lifted object 3 to the frame 5, the tower 2 and the nacelle 4. The wire 39 preferably runs over at least one switch plate 40 which is placed in a suitable place for the purpose. For example, the breaker disk 40 may be mounted mounted in the nacelle. Alternatively, the break plate may be connected to an arm or the like connected to the frame. The second winch can be mounted (connected) to the frame 5, in the tower 2, the nacelle 4 or be connected to a unit (vehicle, bracket, etc.) on the ground.
    The construction further comprises at least one control system with which the movements and functions of the lifting and positioning device are controlled. The control system comprises at least one control unit with which at least one operator can control the lifting and positioning device movements and functions during lifting and positioning of the lifted object 3. The transmission of control information can for instance take place wirelessly or with another transfer method suitable for the purpose. All or parts of the lift or positioning can be done automatically via controlled by at least one software.
    Alternatively, another for the purpose suitable for leveling device can be used to level the lifting and positioning device 1 in the vertical direction of the tower. For example, some type of device can be used with which the lifting and positioning device can climb according to the vertical direction of the tower.
    In alternative embodiments, the construction may consist of at least a first operating arm and at least one second operating arm which are rotatably arranged about at least one axis relative to each other. The control arm can also comprise three or fl your arms.
    In the detailed description of the present invention, construction details which may be obvious to a person skilled in the art may have been omitted. Such obvious construction details are included to the extent required for a proper function of the present invention to be achieved. For example, shafts, bearings, screw connections, hydraulic components, cabling with fl your components are included to the extent required for a satisfactory function for the lifting device to be obtained. Although certain preferred embodiments have been described in detail, variations and modifications within the scope of the invention may be apparent to those skilled in the art to which the invention pertains, and all of these are considered to fall within the scope of the appended claims. It is conceivable, for example, that the tower consists of a different type of site than a site for a wind turbine. It is further conceivable that the construction comprises a counterweight which is preferably connected to the body on an opposite side, or substantially opposite side to the operating arm. It is conceivable that the center of gravity of the counterweight can be arranged to be adjustable relative to the center of the frame and the tower, respectively.
    Advantages of the invention The main advantage of the present invention is a lifting and positioning device with which components can be lifted up in the vertical direction in a wind turbine is achieved. A further advantage of the present lifting device is that the position of the lifting object can change during the lifting. A still further advantage of the present invention is that the lifting device can be moved from one tower to another tower.
