Embodiment Construction

[0067] To illustrate the preferred embodiment of the present invention, now refer to the accompanying drawings in detail, the different operating states of the lifting mechanism 2 of the present invention are shown in figure 1 .

[0068] figure 1 a) shows a side view of the lifting mechanism 2 according to the invention, mounted on a yoke 42 .

[0069] The lifting mechanism 2 comprises a drive device 4 provided as an actuator 4 with a housing 8 and a rod part 6 . The lifting mechanism 2 comprises an attachment part 12 fixed to a connecting part 14 mechanically connected to a slide part 18 slidably connected to a rod part 16 running parallel to The direction of the rod part 6 of the actuator 4 extends.

[0070] The rod part 16 is connected to the frame 20 of the yoke 42 by means of a mounting part 36 . The housing 8 of the actuator 4 is connected to the frame 20 of the yoke 42 via the mounting part 10 .

[0071] An elongated connecting member 22 is rotatably connected to t...

Abstract

A lifting mechanism (2) for lifting an object (46; 34) is disclosed. The lifting mechanism (2) comprises drive means (4; 54) comprising means (10; 52, 50, 56) for being attached to a frame (20) of a lifting device, e.g. a yoke (42). The lifting mechanism (2) further comprises a lifting member (38) provided with means for being connected to a wire (32). The lifting mechanism (2) comprises means for moving the lifting member (38) in an arched movement path (40) relative to the frame (20) when the lifting mechanism (2) is attached to the frame (20), wherein the lifting mechanism (2) is configured to be suspended in only one lifting point (28).

Description

technical field [0001] The present invention generally relates to a device configured to be handled by a lifting device, such as a crane. The invention more particularly relates to a lifting mechanism configured to pitch and / or tilt a load and a lifting device comprising the same. Background technique [0002] Various lifting mechanisms for lifting wind turbine blades have been described. Patent application WO2010124744A1 describes a method and a yoke for lifting a wind turbine blade. While the yoke allows the wind turbine blade to be accommodated and held in a fixed position within the yoke, it is not suitable for pitching the wind turbine blade. [0003] Therefore, when a yoke similar to that disclosed in WO2010124744A1 is used for mounting wind turbine blades, another strategy must be used in order to pitch the yoke when required. Pitching of the yoke can be achieved by means of a crane and multiple wires, by varying the length of a portion of the wires. This method i...
