Definitions

  • the invention relates to a tower crane with a tower of at least one tower element according to the preamble of claim 1. Furthermore, the invention relates to a method for assembling a wind turbine rotor blade.
  • the height of the tower can be increased by the use of additional tower elements.
  • tower cranes have a maximum freestanding hook height. If this is exceeded, the tower crane must be secured by a horizontal anchorage to the structures to be constructed. As a result, the maximum achievable hook height can be significantly increased.
  • Such tower cranes with a building guy are used for example for the construction of wind turbines.
  • the rotor blades When installing such wind turbines, the rotor blades must be guided by the crane during assembly. By default, the rotor blades are guided by ropes from the ground during assembly. The cable pull forces that can be applied by such a floor guide are very small, so that only very low wind speeds can be permitted with such an installation.
  • often result in the leadership of the ropes from the ground space problems for example, when the wind turbine is installed in a forest area in which the space on the ground are sometimes very limited.
  • Object of the present invention is therefore to develop a generic tower crane such that long objects such as rotor blades can be performed during assembly at very high altitudes.
  • a tower crane has a tower of at least one tower element, in particular lattice piece, preferably with a building guy, which is anchored to at least one tie rod horizontal to a building and a vertically movable on the tower guide frame, wherein at least one positioning is adjustably attached to the guide frame ,
  • this positioning part which is adjustably mounted on the guide frame, the distance between the element to be guided, for example the rotor blade and the guide point, can be significantly reduced, so that the object to be mounted can be guided much more stably.
  • the guide frame can be tracked vertically in each case in the tower height. As a result, a guide can be done regardless of the space conditions on the ground. Furthermore, an assembly can be carried out at comparatively higher wind speeds. Preferred embodiments of the invention will become apparent from the subsequent claims to the main claim.
  • two cable guides for moving the guide frame are present, which are adjustable via a Zileilwinde with two cable drums.
  • the guide frame can be moved vertically along the guide frame via the two cable guides.
  • the two cable guides preferably have a cable drum arranged on the tower and a deflection roller arranged on a climbing piece or on the guide piece.
  • the guide frame is U-shaped according to the invention, so that it engages around the tower on three sides.
  • the U-shaped guide frame is angled at its open end to engage around the corner areas of the tower.
  • the guide frame in the corner regions of the tower rollers or plain bearings, over which it is supported during the vertical up and down movement relative to the tower. Since the weight of the guide frame is quite high due to its stable design, the guide frame can be divisible for assembly and transport purposes.
  • a winch is arranged on the guide frame.
  • two independently controllable ends for the independent adjustment of two positioning cables are provided.
  • telescoping struts can be arranged on the guide frame, which on the one hand serve to guide the positioning ropes and on the other hand as a damper serve, if a contact of the leading object, such as the rotor blade and the struts should occur.
  • the guidance points provided on the guide frame for the positioning cables are rotatable about the tower.
  • suitable guides are provided on the guide frame.
  • the guide frame can additionally serve as passenger and / or goods lift.
  • the guide frame can additionally serve as passenger and / or goods lift.
  • two independent cable guides for vertical displacement of the guide frame are necessary here.
  • a balance weight is preferably provided, similar to that known from conventional elevator technology.
  • the invention comprises a method for mounting a wind turbine rotor blade according to one of claims 14 and 15.
  • FIG. 1 shows a tower crane 10, which is connected via a known per se building guy 12 with a wind turbine 14 to be created.
  • the tower crane 10 is used to build the wind turbine.
  • a rotor blade 18 of the tower crane is received via a load cable 16 of the tower crane 10 in order to mount this on the hub 20 of the wind turbine.
  • the load cable 16 is connected in the illustrated embodiment with an adjustment unit 22, the winches for pitch-tilt angle adjustment of the recorded rotor blade 18 has.
  • the rotor blade 18 is connected via corresponding ropes 24 with a rotor blade gripper 26, by means of which the rotor blade 18 can be encompassed in a known manner.
  • the guide frame 30 is vertically movable in the double arrow direction a along the tower 11 of the tower crane.
  • the positioning cables 28 can be adjusted in length via corresponding winches 32.
  • the vertical adjustment of the guide frame 30 takes place in the illustrated embodiment via two cables 34, which can be moved by a drive 36.
  • the drive 36 is arranged in the illustrated embodiment in the bottom region of the tower crane 10.
  • the drive here consists of a two-way winch with two rope drums.
  • the ropes 34 are guided over deflection rollers 38, which are provided in a crane tower climbing unit 40.
  • FIG. 2 In the detail view according to FIG. 2 is a slightly modified variant of the FIG. 1 shown.
  • a guide frame 30 is shown, wherein the vertical displacement here Rope 34 is used, which in turn is guided over deflection rollers 38 of a Kranturmkletter noticed 40.
  • this cable 34 runs over corresponding winches 42, which are arranged in the guide frame 30. By adjusting the winches 42, the cable 34 is extended or shortened, so that here the vertical movement of the guide frame 30 is completed.
  • FIG. 3 shows a cross-sectional view of the guide frame 30, from which the arrangement relative to the tower 11 of the tower crane is clear.
  • the tower 11 is connected via a Bauwerkabschreib 12 with the wind turbine 14.
  • the guide frame 30 has a U-shape, as in FIG. 3 shown. However, at its open end, the U-shaped guide frame 30 is angled to encompass the corner areas of the tower, as illustrated by the position number 44. In the area of the corner stems 13 of the tower 11 not shown in detail roller or sliding bearings 46 are provided in the guide frame.
  • the here in FIG. 3 not shown in detail roller or slide bearing guide can be designed to pivot towards the tower to simplify installation.
  • FIG. 4 an alternative embodiment of the guide frame is shown.
  • the guide frame on corner guide elements 50 which are placed on the respective Eckstielen 13 of the tower 11.
  • Die Eck Replacementsiata each contain three roller bearings 52, 54 and 56. They are each connected via connecting elements 58 with each other.
  • FIG. 5 shows a crane climbing device 40 according to another embodiment of the invention. This is clamped as the last tower piece and thus always remains at the top position on the tower crane 10.
  • the position of the guide roller 38 and a hoist 36 'for vertical movement of the guide frame 30 is shown.
  • the alignment of the rotor blade can advantageously take place via the guide frame 30 arranged on the tower 11.
  • the crane operator can have the vertical guidance of the rotor blade or attachment via a remote control and a camera.
  • the crane operator also has a remote control and a camera and a controller for moving the positioning ropes 28.
  • the pitch-tilt angle adjustment of the rotor blade along a longitudinal axis takes over the adjustment unit 22.
  • FIGS. 6 and 7 Details of a structurally modified guide frame 30 with modified corner guide elements 50 '.
  • the corner guide elements 50 'shown here each have two roller bearings 52' and 54 ', which are placed on the corner stems 13 of the tower 11, not shown here.
  • roller bearings 52 'and 54' are mounted in a pivotable plate 70.
  • the sheet is pivoted to a mounting position in which it can be secured by a bolt 68.
  • the guide frame can be approximated to the corner posts 13 of the tower 11.
  • this can then be brought into the mounted end position and there, as in FIG. 6 be shown again bolted.
  • the roller bearings 52 'and 54' in contact with the corner stems 13.
