As explained above, first major component can include lifting device, and shown in Figure 9 is four lifting devices 69, and each end 71 and every side of 72 all are provided with two.These lifting devices 69---it can be driven by electric motor or other suitable device---are connected to wire or similar devices (not shown in Figure 9), described wire or similar devices are connected to anchor 20 near the wind turbine hub, as indicated above, thereby maintenance of equipment 50 can reduce or raise.

According to combining the described content of other mode of execution of the present invention, maintenance of equipment 50 comprises one second major component 64, this second major component includes a for example object of instrument or working platform 66, working platform 66 hangs by a suspension arrangement 65, and this suspension arrangement is connected to movably suspension arrangement 68.These movably suspension arrangement 68 can move along first major component 62, for example on element orbit-shaped or tubulose of part 71,72,73 and 74, move, preferably drive by electric motor or similar devices.Also as indicated above, maintenance of equipment 50 can include a counterweight part (not shown in Figure 9), and described counterweight part can design and part 65 and 68 corresponding parts.Being appreciated that counterweight part and working platform need not be mechanically is connected, but can so control: when use equipment 50, they will be provided with toward each other.Counterweight part can be used for carrying necessary outfit, for example battery or other power supply device, compressor etc.

In addition, the maintenance of equipment 50 that is shown among Fig. 9 includes a fastening and/or stabilizer 80, and when equipment 50 is positioned at one will carry out the certain height of work the time, described device 80 can be used for stabilizing equipment 50, and can also fastening apparatus 50.For this reason, device 80 includes two flexible fasteners 81 and 82, and it can be a flexible strand of bundle element known in the prior art---for example can be by the pipe member of pressurized air inflation, and in this case, it expands and reduces length simultaneously.As shown in the figure, these elements 81 and 82 are connected to the fastening beam 83 and 84 that is positioned on each end 71 and 72.Fastener 81 and 82 so is arranged on beam 83 and 84 by fixing device 85: its position can for example laterally be regulated and be fixing.In idle state, these elements 81 and 82 can be intersected with each other as illustrated in fig. 9, thereby for example allow the structure of rotor blade to pass between element.As mentioned above, fastener 81 and 82 is connected to fixing device 85, and this fixing device also can be used as the device that pressurized air is imported in the fastener or draw from fastener.In addition, fastener 81 and 82 can so be connected to securing means 85: fastener 81 and 82 can rotate, keep simultaneously tightness.Fastener 81 and 82 can fill with air by for example one or more electrically driven (operated) compressors.Air can be pumped into fastener independently or discharge from fastener, and for example, the pressure in each fastener can be controlled.Should be appreciated that these fasteners 81 can be provided with different length with 82, for example corresponding with the different length of sidepiece 73 and 74.

When for example when the rotor blade of wind turbine uses this maintenance of equipment 50, lifting device 69 is connected to the rotor place that is positioned at rotor blade or near the anchor it by wire or similar devices (not shown), and the height of equipment 50 can be regulated by lifting device 69, this lifting device 69 for example by one for example rest on the ground, personnel within the working platform 66 etc. and control by suitable control gear (not shown)s such as for example operating handles.When arriving the height of expectation, lifting device 69 stops.As is well known, can start break on---for example integrated with electric motor break---and maintain equipment, perhaps, lifting device can be equipped with gearing, worm gear of self-locking etc.

In order to make equipment stable, and fastening apparatus further with respect to rotor blade, can start securing means 80 now, this realizes by via fixing device 85 pressurized air being incorporated in fastener 81 and 82.These devices can be connected to as described above to fastener---the flexible strand of bundle that for example the has air---compression set of filling, thus it shrinks along its length and broad ways expands.Thereby for example rotor blade will be pushed and clamp to fastener 81 and 82.Maintenance of equipment 50 will be located with respect to for example rotor blade thus securely, and can not move under the influence of wind etc.In addition, can control independently because be present in the air pressure and/or the volume of the gas in each fastener, so, thereby the position of maintenance of equipment for example also can be regulated the position of working platform in this way.For example, if the air of extra quantity imports in the fastener 81 that is shown among Fig. 9, and/or air discharges from fastener 82, then maintenance of equipment will---it is firmly grasped by fastener---move on to the right side with respect to for example rotor blade, vice versa.

Figure 10 shows the maintenance of equipment among Fig. 9, but observes from another angle.Thereby identical reference number is used for components identical and feature, and is not further described at this.Yet clearly show that here: for example the object of working platform 66 is suspended from the suspension arrangement 68 movably, and these suspension arrangements include a framework 90, and each end of this framework has 91 and one groups of top guide wheels 92 of one group of lower guide wheel.In an example shown, framework 90 is positioned at the inboard of first major component, can cross securing means that is used for fastening beam 83 and 84 and the erecting device that is used for lifting device 69.Guide wheel 91 and 92 is designed on the edge, the i.e. pipe of first major component, and be appreciated that these wheels so are provided with: it can turn over a little angle at least with respect to framework 90, can pass through the curved section of first major component, for example end 71 and 72.In addition, this framework 90 is equipped with a drive motor 93, is used for moving framework 90 along first major component.Will in conjunction with one similarly, with first device in opposite directions moveable suspended device of placement explain the feature relevant further with this drive motor.It comprises that is for example passed through an attachment arrangement---for example hook, ring or similar devices 98---, and be used to carry the similar framework 94 of counterweight (not shown), this counterweight can include a battery power source etc.This framework 94 includes similar wheel etc., described in framework 90 and drive motor 95.It has for example drive unit of gear forms, is used for interacting with the tooth bar 97 that for example is positioned at the first major component inboard.In Figure 10, it only illustrates on part 73, but significantly, it will be along all length setting of first major component.An engagement link 96 is used to make driving motor 95 to contact on first major component with for example tooth bar 97.Naturally, framework 90 can be provided with similar device.

As mentioned above, two parts of second major component---for example framework 90 and framework 94---will radially be provided with each other in opposite directions, thereby can synchronously move.They can mechanically connect as described above, and for example they are arranged on the common framework.In mode of execution illustrated in fig. 10, they also can mechanically be coupled by for example cable, wire etc.Especially, it can---for example include the movable fixture of guide wheel and following guide wheel---by one or more other movable fixture (not shown)s that are positioned on first major component and be coupled, in this case, can be by the framework 90 and the first other movable fixture being linked together with bar or similar devices, with similar bar the first other movable fixture and the second other movable fixture are linked together, by bar or similar devices the second other movable fixture is connected to framework 94 again and between two frameworks 90 and 94, forms a connection.Be appreciated that and use one, two, three or more so other movable fixtures, and in this way, two parts that---for example framework 90 and 94---will synchronously move along first major component.Be appreciated that also that when relating to a mechanical connection drive motor has been enough just.Yet except using a mechanical device, two parts can for example be controlled electrically synchronously to move, and for those skilled in the art, this is obvious.For example, drive motor can be stepper motor and/or servomotor, can form radio contact between two parts wait.

In conjunction with Figure 10, find that also two fasteners 81 and 82---for example fill with air---to fall when being not activated, meaning that rotor blade is directed in the equipment and---for example equipment 50 is promoted to rotor blade---between two fasteners 81 and 82 may be difficult.In order to alleviate this difficulty, support device can be arranged on first major component, for example is positioned on the part 74 that is used for fastener 82 and is positioned at the part 73 that is used for fastener 81.In addition, special device can be arranged on fastener 81 and 82, is used to keep a suitable position.This device can for example be a telescopic rods, and it reaches the fixed element 85 that is positioned on the fastening beam 83 from a fixed element 85 that is positioned on the fastening beam 84 in pipe member 81 and 82.

As mentioned above, fastener 81 and 82 is installed in rotation on the fixing device 85.Thereby when securing means had been activated and has been pressed on the surface of rotor blade for example, maintenance of equipment can promote or reduce and need not to make that securing means quits work, because these fasteners will roll surfacewise.

In addition, notice: maintenance of equipment 50 can be equipped with wheel or similar elements, is used to abut against for example surface support of rotor blade.When equipment lifting and/or when reducing, these wheels also can be used to abut against the tower body of rotor blade or wind turbine and support apparatus 50.

In Figure 11, show working platform 66 enlargedly.It can light weight material---for example aluminum pipe---be designed to, and its size is suitable for one or two personnel.Big platform also is fine.As shown in the figure, platform design has the vertical recess of central authorities or the breach 101 that are arranged in guardrail, and when the maintenance of equipment that has platform 66 was raised or reduces, this recess or breach can be used for holding the edge of rotor blade.For this reason, platform 66 is provided with protective gear, for example be arranged in the roller or the similar devices 102 of recess 101, and property illustrates as schematically shown in Figure 11.This roller 102 will contact the edge of rotor blade, and promote and the reduction process in roll along the edge of rotor blade, thereby prevent the contact that is harmful to.Can be provided with and surpass one roller.In addition, platform 66 is equipped with further protective gear, prevents platform and for example harmful contact between the rotor blade during working on the rotor blade.This protective gear for example can be the form as 103 indicated protecting strips.This can for example include foam material, rubber material or other suitable material arbitrarily.In addition, can adopt the pipe of inflation.Though only show single 103, can the bar more than is set.Preferably, this can be provided with near the bottom of platform 66, and be provided with on all sides of platform.

Platform can be so suspended on the equipment from be shown in Figure 10 by a hook, ring 104 or similar devices: it can for example freely rotate by hand.And it can be by for example being rotated by the power plant that personnel controlled that are positioned at platform.Platform will be equipped with the control gear (not shown), and this control gear includes the device that is used to promote and reduce equipment---and for example be used to control lifting device 69 (Fig. 9 and 10) and be used for controlling along the position of rotor blade periphery by controlling and driving motor 93 or 95 (Figure 10).In addition, also be provided with the device that is used to control fastener 81 and 82.Control gear can include operating handle and/or other suitable control input device, and can be used for controlling maintenance of equipment and platform itself---their position for example.In addition; notice: if necessary; can control each device; for example can control individually lifting device 69; for example in order to the inclination of control apparatus, this is necessary, because under many situations; when keeping in repair when shutdown, the edge of the rotor blade of wind turbine can tilt for vertical direction.Be also noted that: equipment or platform can be equipped with a gyroscopic apparatus, for example in order to maintain predetermined inclination, angular orientation etc.

At last; be noted that about platform illustrated in fig. 11 this platform can be designed to: preferably personnel are protected by being provided with one, make it avoid the influence of wind, rain etc. by the top cover of the transparent material manufacturing of for example plexiglas or similar material etc. and the lid that is used for side by forms such as roller shutters or veil.Be also noted that: platform and/or maintenance of equipment are equipped with lighting set, luminous device etc., also can usage platform and/or maintenance of equipment when not having sunlight with permission.Platform can be provided with a little capstan winch or similar devices to promote and/or to reduce necessary object, instrument, spare part etc.Thereby, will need not when these parts of needs, platform and maintenance of equipment to be dropped on the ground.
