Definitions

  • the present invention relates to a rigging device for lifting a load by a crane, and to a method of lifting a component of a wind turbine by a crane and the rigging device.
  • Fig. 4 shows a rigging device according to the prior art.
  • the rigging device comprises a beam 30 and two slings 51, 52, wherein each sling 51, 52 is connected at one side to a respective end of the beam 30 in its longitudinal axis. Another side of the respective sling 51, 52 is connected to a carrier device in the shape of a pendulum 70 of a crane.
  • the beam 30 carries a load such as a blade 2 of a wind turbine.
  • the pendulum 70 can be tilted by an actuator 60 so that a rigging length of the sling 51, 52 is adjusted.
  • At least one of the slings 51, 52 can be replaced by a hydraulic cylinder for adjusting the rigging setup during the lifting operation.
  • a rigging device for lifting a load by a crane.
  • the rigging device comprises a beam and a first pulley mounted to the beam at a first end in a longitudinal axis of the beam, wherein the first pulley is configured to receive a first sling, and the first sling is configured to be connected to a carrier device of a crane or to the load.
  • the first pulley is mounted to be eccentrically rotatable with respect to the beam, and the first pulley is connected to a first actuator which is configured to rotate the first pulley.
  • the rigging device of the present invention consists of few parts which can be assembled with the first pulley as a center piece that is born offset from its center. Together with a reaction arm in the shape of the first actuator, a rigging length can be adjusted under load. By operating the first actuator, the first pulley is rotated, which results in an adjustment of the rigging length.
  • the lifting operation can be faster because the length can be adjusted "under load” so that the load does not have to be unloaded before adjusting the sling length.
  • a bottom surface of the lifted load can be aligned with a landing surface.
  • the lifting operation by the rigging device of the present invention can also be safer because the load does not need to be lifted again after the length adjustment. If a load, such as a nacelle, would be unloaded downwards again, the crane setting, particularly a cog wheel, could otherwise be offset from a support line.
  • a particular advantage of the present invention is to enable a rigging adjustment under load, especially an adjustment under a heavy load, while the prior art adjustment was restricted to low load cases only.
  • the adjustment by use of the rigging device of the present invention can be used to achieve faster lifting and landing operations which results in less time spent during the lifting operation.
  • a size of a hydraulic cylinder can be reduced compared with the cylinder of the prior art actuator shown in Fig. 4 . This can be achieved because the rigging device of the present invention exhibits much lower friction in the moving parts, so lower forces need to be applied.
  • a precision railing used for a sliding mechanism is not necessary in the present invention.
  • the first pulley comprises a core made of a first material, preferably metal, and a second material at a circumference of the core, wherein the second material and the first sling have a smaller friction coefficient that the first material of the core and the first sling.
  • the second material can comprise a resin-bonded, fabric-reinforced composite and/or Polytetrafluorethylen (PTFE).
  • the beam comprises a plurality of beam portions, preferably pipes, wherein the beam portions are mounted to each other along the longitudinal axis of the beam by means of flanges.
  • This embodiment achieves a modular concept, where the final beam length can be adapted to the load, such as to wind turbine nacelles having different sizes.
  • the rigging device further comprises a second pulley mounted to the beam at a second end in the longitudinal axis of the beam, wherein the second pulley is configured to receive a second sling, and the second sling is configured to be connected to the carrier device of the crane or to the load.
  • the second pulley is mounted to be eccentrically rotatable with respect to the beam, and the second pulley is connected to a second actuator which is configured to rotate the second pulley.
  • two adjustment stages are implemented by the first and second pulleys to increase the range of adjustment.
  • the beam, the first sling and the second sling form a triangle, when the first sling and the second sling are either connected to the carrier device of the crane or to the load.
  • This configuration enables a well-balanced rigging device, which is configured to tilt the load.
  • the second pulley is not essential for the present invention and can be omitted.
  • the rigging device further comprises another pulley mounted to the beam at the first end or a second end in the longitudinal axis of the beam, the other pulley is configured to receive another sling.
  • the other pulley is mounted to be eccentrically rotatable with respect to the beam, and the other pulley is connected to another actuator which is configured to rotate the other pulley.
  • One of the first sling and the other sling is configured to be connected to the carrier device of a crane, and the other one of the first sling and the other sling is configured to be connected to the load.
  • another adjustment stage is implemented by the pulley and the other pulley to further increase the range of adjustment.
  • one of the rotation planes of the first pulley and the other pulley is arranged in parallel to the longitudinal axis of the beam, and the other one of the rotation planes of the first pulley and the other pulley is arranged perpendicularly to the longitudinal axis of the beam.
  • Any pulley is usually vertically arranged.
  • the first actuator comprises a hydraulic cylinder, an electrically operated spindle or a spring actuator comprising a biased spring.
  • a method of lifting a component of a wind turbine by a crane and the rigging device is provided.
  • the component of the wind turbine is a nacelle or a blade.
  • the component is a blade
  • the rigging device is used to tilt the blade.
  • the rigging device of the present invention can work under extreme load and can be implemented in a base of a yoke, instead of having an extra yoke with hydraulics, for example, above a blade yoke.
  • Fig. 1 shows a rigging device 1 according to an embodiment
  • Fig. 2 shows an operation of the rigging device 1.
  • the rigging device 1 is configured to lift a load 2 by a crane.

  • the first pulley 4 is mounted to be eccentrically rotatable with respect to the beam 3, and the first pulley 4 is connected to a first actuator 6 which is configured to rotate the first pulley 4.
