Windmill installation, manipulator for handling a part of the windmill installation, and a combination of such a windmill installation and manipulator
The invention relates to a combination of a windmill installation and a manipulator for handling a part of the windmill installation, particularly but not exclusively a rotor blade. The manipulator can also be used to handle other parts of the windmill installation, such as the generator, the gearbox etc.
A crane and method for handling a part of a windmill installation is disclosed by US 8,757,402. This citation mentions the application of a crane with a manipulator connectable to a boom of the crane in a torque-rigid manner so that the position and/or alignment of the rotor blade received in the receiving unit of the manipulator can be fixed relative to the boom. Although this citation mentions that the position and/or alignment of the rotor blade can be fixed relative to the boom of the crane, this does not address the problem that the position and/or alignment of the rotor blade is still relatively undefined with respect to the upstanding mast of the windmill installation, particularly when the boom of the crane extends to great heights. It remains therefore a challenge with the solution according to US 8,757,402 to securely and precisely position and align the rotor blade with reference to the hub of the windmill installation, notwithstanding the eventual fine tuning that can be provided with the manipulator since the position of the manipulator itself is relatively undefined with reference to the upstanding mast of the windmill installation. This problem further worsens when strong winds blow near the nacelle of the windmill installation, which is normally the case since the windmill installations are evidently located in windy areas.
In the applicants co-pending and at the filing date of this application still unpublished patent application NL 2017381 it is described that distant from a base of the crane the boom is provided with a guide element which is arranged to cooperate during use with an upstanding mast of the windmill installation so as to restrict relative horizontal movement of the boom distant from the base with reference to the upstanding mast of the windmill installation. Applying this guide element on the boom at the far end from the base, and providing that this guide element at least partly fits around a circumferential surface area of the upstanding mast of the windmill installation effectively prevents relative horizontal movement of the boom distant from the base with reference to the upstanding mast of the windmill installation. In fact by this arrangement on top of the boom a point of fixation is provided that can operate as a secure base for the manipulator with a defined position relative to the upstanding mast of the windmill installation. This not only improves security and accuracy, but also makes possible that the crane can handle larger weights. In other words the capacity of the crane is also improved .
A problem of the published prior art such as US 8,757,402 that with the construction of NL 2017381 has not yet been resolved, is the problem that maintenance on an existing windmill installation always requires the costly use of a ground-based crane. Correspondingly when the windmill installation is offshore a suitable and stable support for the crane must also be made available.
It is therefore a first object of the invention to make maintenance on an existing windmill installation less costly.
It is a further object of the invention to securely and precisely handle all sort of parts of a windmill installation .
In a first aspect of the invention a combination of a windmill installation and a manipulator for handling a part of the windmill installation is proposed wherein the manipulator is mountable or mounted on the upstanding mast of the windmill installation. This avoids the use of the costly crane, while due to the mounting of the manipulator on the upstanding mast of the windmill the combined construction is relatively insensitive to weather conditions, in particular to wind so that the manipulator can securely and precisely handle all types of equipment to be mounted or dismounted from a nacelle of the windmill installation.
The manipulator can be a dedicated robot for handling a rotor blade, or a crane for handling ancillary equipment to be mounted in or retrieved from a nacelle of the windmill installation .
Suitably the manipulator has releasable clamps fitting around the upstanding mast of the windmill installation. These clamps enable the climbing up and down of the manipulator along the upstanding mast of the windmill installation.
It is of particular advantage that the upstanding mast of the windmill installation is provided with attachment means for a suspension wire or suspension wires. Applying such attachment means for suspension wires to the upstanding mast of the windmill installation breaks with the habit to leave the upstanding mast as clean as can be. The revolutionary idea to provide the upstanding mast with such attachment means opens an avenue of new possibilities and cost savings as will become apparent from the following discussion.
In connection with what is mentioned in the previous paragraph it is preferable that the manipulator is provided with a winch or winches. Advantageously then the suspension wire or suspension wires connect to the winch or winches of the manipulator. In doing so the manipulator can autonomously move up-and-down the upstanding mast of the windmill installation, so that no further means are required other than the manipulator itself to place the manipulator in the proper position to execute maintenance on the windmill installation.
To assist the manipulator in moving up and down the upstanding mast of the windmill installation it is preferred that the manipulator is provided with a guide wheel or guide wheels for guiding the manipulator along the upstanding mast of the windmill installation.
It is amazing that embodying the attachment means in the form of an aperture or apertures provided in a shell of the upstanding mast of the windmill installation already may suffice to benefit from the advantages of the invention.
Suitably in the aperture or apertures a removable insert is placed that has an eye for receiving the suspension wire or suspension wires.
It is however also possible that the attachment means comprise a support that is welded on the upstanding mast of the windmill installation.
The invention is also embodied in a windmill installation comprising an upstanding mast and rotor blades mounted on top of the upstanding mast, wherein the upstanding mast has attachment means for a suspension wire or suspension wires.
A preferred feature of the windmill installation according to the invention is that the upstanding mast has an aperture or apertures in an upper region of the upstanding mast.
It is further preferred that in the aperture or apertures a removable insert is placed that has an eye for receiving the suspension wire or suspension wires.
Alternatively the attachment means comprise a support that is welded on the upstanding mast of the windmill installation .
The invention is further embodied in a manipulator for handling a part of a windmill installation, particularly but not exclusively a rotor blade, wherein the manipulator is mountable or mounted on an upstanding mast of the windmill installation .
Preferably the manipulator has at least one releasable clamp that is fixable around the upstanding mast of the windmill installation.
It is further preferred that the manipulator is provided with a winch or winches that are connectable to a suspension wire or suspension wires that also connect to the upstanding mast of the windmill installation.
Advantageously the manipulator is provided with a guide wheel or guide wheels for guiding the manipulator along the upstanding mast of the windmill installation.
The invention will hereinafter be further elucidated with reference to the drawing of an exemplary embodiment of a crane according to the invention that is not limiting as to the appended claims.
In the drawing:
-figure 1, 2 and 3 show the combination of a windmill installation and a manipulator for handling a part of the windmill installation at a lower elevation, a medium eleva tion, and an upper elevation respectively;
-figure 4 shows a detail of the manipulator according to the invention;
-figure 5 shows a detail of the upstanding mast of the windmill installation with a first embodiment of an attachment means;
-figures 6.1 and 6.2 show the detail of figure 5 completed with an insert in the attachment means;
-figure 7 shows a detail of the upstanding mast of the windmill installation with a second embodiment of an attachment means; and
-figure 8 shows a detail of the upstanding mast of the windmill installation with a third embodiment of an attachment means .
Whenever in the figures the same reference numerals are applied, these numerals refer to the same parts.
Making first reference to figure 1, figure 2 and figure 3 it shows a combination of a windmill installation 2 and a manipulator 3 for handling a part of the windmill installation 2, particularly but not exclusively a rotor blade 4, wherein the manipulator 3 is mounted on an upstanding mast 5 of the windmill installation 2. In these figures 1, 2 and 3 it shows that the manipulator 3 is a crane 3' which in particular can be used for handling ancillary equipment to be mounted in or retrieved from a nacelle 6 of the windmill installation 2. The manipulator 3 can however also be embodied as a robot for handling the rotor blades 4.
The manipulator 3 preferably has releasable lower and upper clamps 7, 8 fitting around the upstanding mast 5 of the windmill installation 2. Figure 5 shows a detail of the manipulator 3, wherein particularly the lower clamp 7 is shown and from which it is clear that the lower clamp 7 may be provided with a tensioning device 7' to provide a tight fit around the upstanding mast 5 of the windmill installation, which makes it possible to adjust for the varying diameter of this mast 5.
The upstanding mast 5 of the windmill installation 2 is further provided with attachment means 11 for a suspension wire 9 or suspension wires. The arrangement of the attachment means 11 will be further explained hereinafter with reference to figures 5 - 8.
Further it is shown in figures 1-3 that the manipulator 3 is provided with a winch 10 or winches, and that the suspension wire 9 or suspension wires connect to the winch 10 or winches of the manipulator 3, so that the manipulator 3 can autonomously move itself up or down along the upstanding mast 5 of the windmill installation 2.
Although it is not shown in the figures it is preferred that the manipulator 3 is provided with a guide wheel or guide wheels for guiding the manipulator 3 in order to assist its movement along the upstanding mast 5 of the windmill installation 2. The movement itself along the upstanding mast 5 is depicted by the subsequent figures 1, 2 and 3 which show a lower elevation, a medium elevation and an upper elevation of the manipulator 3 along the mast 5, respectively.
Making reference now to figure 5 it shows a first embodiment of attachment means 11 that comprise an aperture 12 that is provided in a shell 5' of the upstanding mast 5 of the windmill installation. Normally there are multiple apertures.
Figures 6.1 and 6.2 show that in each aperture 12 a removable insert 13 is placed that has an eye 14 for receiving a suspension wire 9 or suspension wires. Figure 6.1 shows an outside view of the mast 5, whereas figure 6.2 shows an inside view of the mast 5, wherein of course the eye 14 is not visible .
Figure 7 and figure 8 show two different embodiments wherein the attachment means 11 comprise supports 15, 16 that are welded on the upstanding mast 5 of the windmill installation 2. In the embodiment of figure 7 also an eye 14 is present to receive a suspension wire 9 or suspension wires.
Although the invention has been discussed in the foregoing with reference to exemplary embodiments of the combination of the windmill installation and manipulator of the invention, the invention is not restricted to these particular embodiments which can be varied in many ways without departing from the invention. The discussed exemplary embodiments shall therefore not be used to construe the appended claims strictly in accordance therewith. On the contrary the embodiments are merely intended to explain the wording of the appended claims without intent to limit the claims to these exemplary embodiments. The scope of protection of the invention shall therefore be construed in accordance with the appended claims only, wherein a possible ambiguity in the wording of the claims shall be resolved using these exemplary embodiments.
