专利说明:

The present invention relates to a method for use in single blade switching on a wind turbine using a game system located near the wind turbine foot, and a device for use in the practice of the method.
When changing or mounting a single blade on wind turbines, the known mohil cranes which take some time to set up are typically used, eg which are relatively expensive to operate. This embroidery has to some extent been remedied with the device specified in VVO 201 in 050812 A1, tiftra ApS, where an earth-based play is placed at a distance from the wind turbine's foundation, which is connected to a wheel wheel arrangement in the nacelle or on the rotor , which game is used for hoisting objects, including blades for wind turbines, to relevant mounting locations where the objects raised with the game are controlled, and carried by the game's wire. However, practice has shown that the use of the game is not optimal for all types of wind turbines for raising the blades to a relevant mounting location, as moving the ground-based game is not possible during the lifting of the blade where its wire carries the weight of the blade. In particular, the last part of the lifting of the blade to the mounting point, the blade must provide an approximately vertical displacement, which is only possible if the pull in the wire of the game is extinguished, so that the wire controlling the displacement of the blade and also carrying it is almost vertically vertical from the wire. attachment points on the wind turbine's hub, nacelle, all other blades, which is incompatible with the blade having to be hoisted the last piece of file mounting position on the wind turbine's fuselage. In US 2007/0290428 Al is specified a device for use with a ground-based game, file mount a blade for a wind turbine, where the blade is raised from a starting position on the ground, at the foot of the wind turbine tower, and file the mounting location of the wind turbines hub, where the wind turbines other two blades or placed in an symmetrical position around the wind turbines vertical center axis, the device includes a guide element lost between the tower of the windmill and the earth, and in the minds of it a support device which is substantially located in the air of the guide element and which carries at least a portion of the weight of the blade during transport: of the wing between the ground and its coinage location on the hub of the wind turbine, at least one wire extends between the supporting device and the wind turbine blade, whereby the length of said wire between the tfe device and the wind turbine blade can be adjusted. When handling blades for wind turbines with the device, this partly comprises a wire attached to the part of the blade which is affixed securely to the wind turbine hub, and a wire whose end comprises a lifting bag in which one of the tips of the blade is arranged during displacement of the blade between The earth and the monphage site. The weakness of this device is that faith games are used for placing the milling blade at the monfage site in addition, the supporting device is placed hanging in a wire, which will cause instability during operation with it.
IVVO 2011 050812 discloses a ground-based game located at a distance from the foot of a wind turbine, comprising throwing blocks placed on the nacelle of the wind turbine, where the game's wire is used as gold and the lifting and lifting of a load between the ground and a relevant mounting location on the wind turbine's hub or in the nacelle . This game can hi, a. is used for raising a wing file at the monfage site on the wind turbine hub. where the wind turbine's other blades are arranged in a symmetrical position around the vertical center axis of the wind turbine. However, as stated above, it may be difficult to control, in particular, the last part of the lift where the wing must provide an approximately vertical displacement towards the hub of the wind turbine where the mounting flange is to be secured. changing the angle of the wire carrying and controlling the position of the blade so that it is approximately suspended vertically from the throw blocks.
Thus, there is a marked need for an alternative and better solution, to be able to control the last part of the lift of a wind turbine blade, which is lifted between a position at the foot of the wind turbine and to the mounting location of the wind turbine hub, using the jonlbaserei gaming system, whose wire is used both for displacement as well as for controlling the displacement of a wind turbine blade between a position at the actual wind turbine's foot and the mounting location, and thus the invention is intended to provide a method for single-turn shifting which ensures better control and positioning of the last part of the wind turbine. the lift of a wind turbine blade, and a device for use in the practice of the method.
Such a method ten! carrying out the eocelt blade clamp on a wind turbine using a gaming system located near the wind turbine feeder, which gaming system comprises the chassis blocks for anchoring on / or the windmill on the windmill, or alternatively on other mounted blades on the wind turbine hub are characterized by the following steps; -mounting of a lightweight crane in the naoelle »placing a gaming system near the foot of the wind turbine» placing a first clamping means with wire hoi and / or crawler clamp! on the blade, closest to its mounting facilities for mounting on the wind turbine hub, and closing the clamping means - placing another germ member with wire wrench and / or crawling on the blade, closest to its tip, and closing the second clamping member - establishing at least one fixed wire connection between the first clamping means and the second germination means, and attaching the lifting wire of the ground-based game system to the wirebjui respectively on the first and second germs and at least one crawl, on one of the two clamping means, and further to the throwing blocks "Raising the throwing hooks with the lightweight crane to relevant anchorage points on / in the naoelle or on other mounted blades on the wind turbine - anchoring of the throw blocks on / in the naol or on other mounted blades on the wind turbine - initiating lifting of the blade by the ground-based gaming system, while supporting the blade tip by using a smaller mobile earth-hauled lifter, indti At the tip of the blade, fh of the ground surface - raising the blade by means of the grounding winch system to a position below its mounting position on the hub - reducing the drag of the grounding play wire so that the wire is oriented approximately vertically, or at the preferred mounting angle for the wing - activating the crawler splice on the ground-based game wire for displacing the blade to the wind turbine hub mounting site-anchoring the blade on the wind turbine hub-opening of the germ nut, and hoisting them with the ground-based game release of the ground-based game casts, and lifting of this with the lightweight crane »removal of the lightweight crane
The process is distinguished by the fact that the last part of the displacement of the wind turbine blade takes place by activating the crawl play on the cleric organs, whereby these bearing wings are displaced upwards on the wires of the ground-based game, which is positioned in advance by the lord-based game! position, hanging down from a selected position on the nacelle, alternatively on the hub or wings already mounted on the current wind turbine. Since the wires of the terrestrial game are approximately at rest, the features of the terrestrial game being constant, the said last part of the displacement of the blade to this mounting position on the wind turbines hubs can be performed with relatively high accuracy, and consequently also faster than the known ones. techniques. In addition, it will be more manageable only to operate the crawler during the last part of the shift of the blade to the mounting position. However, the terrestrial game can also be used in combination with the crawl game.
A device for carrying out the method according to the invention comprising a first clamping means and a second germinating means for positioning and releasably fastening on a wind turbine blade, respectively near its mounting facilities for mounting on the wind turbine hub, and on the blade closest to its tip, is characterized by substantially inverted U-shaped frame members, the first leg of which is fixed and whose second is pivotally and ameterably mounted to the bottom of the inverted U-shaped frame member, and slidable between an open position where the relevant part of the wing can pass in towards the bottom part between the first and second legs, and a closed pessifion in which the second leg is displaced in the direction of the first leg where the inverted U-shaped frame element in alpha substantially encloses, and is pressed against the wing by a first actuator, where on each side of the bottom part is found with a ground based game wires cooperating first wire wheel, where respectively f first, fixed legs and the second, pivotally adjustable legs on the clamping member closest to the wing mounting facilities for mounting on the wind turbine hub, include outer girders with the ground-based game wires, other cooperating wired ui, and at least one germ member including one with the ground-based winch wires cooperating crawler spl
The blade is thus carried by two U-shaped frames interconnected by staggers, one leg of which is slidable so that the wing is clamped between the legs of the U-shaped frames. In this position, the wing is then raised by the wires of the ground-based game, by the U-shaped frames are controlled and carried on the wires of wire wheels mounted on the frames. In the initial phase, the blade tip is briefly obstructed by a smaller mobile lifting unit to protect it. Then the blade is moved up and steered upwards towards the mounting point on the hub of the mommy, by the pull of the ground-based game in the wires, which also carry the wing and the device, in whose li-presumption strikes, the wing is clamped. The pull of the Ground-based spindle is extinguished when the blade arrives at a predetermined position relative to the mounting location so as to obtain a preferred angle of entry between the wires and vertically ensuring an optimal insertion angle of the mounting flange of the blade and the mounting flange of the hub. position of the wires of the ground-based spindle, the collision spring (s) are actuated, thereby raising the blade the last piece upwards to the mounting position at an appropriate angle of entry relative to the hub, in order to be able to rotate the blade so as to bring the holes into the wing mounting flange to overlap the holes in the hub mounting flange, the second wire wheels cooperating with the ground-based spindle may be pivotally mounted on the first, fixed leg and the second rotatable, adjustable leg on the clamping member closest to the wing mounting facilities for mounting on the wind turbine hubs, and may be displaceable by another actuator.
In this way, the blade is activated by activating the other actuators so that the blade can be slightly rotated so that the noise of the mounting flanges on the blade and the hub can be overlapped respectively, in order to ensure a good retention of the blade disposed in the device, and in order to avoid damaging its surface during handling thereof, the germs may be provided locally on their mutually facing sides, at least where they come into contact with the wall surface, with an elastic resilient coating whose surface is anti-slip.
This results in good retaining of the blade and does not damage its surface during lifting and π ed hoisting between the ground and the mounting point on the hub.
In order to ensure a certain distance between the clamping means, the clamping means may comprise facilities for securing at least one, preferably several bars of the device, for maintaining a preferred spacing between the clamping members in their mounted position on the blade, during the up and down hoisting this one.
In order to prevent damage to the wing surface during handling with the device according to the invention, the bottom part and 1 of the at least one of the legs of the U-shaped frame element can comprise at least one transverse beam, the ends of which can be provided with adjustable pressure shoes, the free ends of which are oriented towards the area bounded internally by the U-shaped frame member to a level below the wing-facing side of the bottom portion and at a distance from the side facing the wing surface of the actual leg, and which free-ended surfaces are constituted by an elastic concave great material.
This results in the file facing side of the bottom part of the U-shaped frame element coming into contact with the surface of the blade during handling thereof.
