The floating offshore wind turbine 10 described above is constructed (arranged) at a predetermined position on the sea using the boom boat S as shown in Fig. 1, for example. The boom ship S is equipped with a construction device 50 of the offshore windmill 10 to be described later. The construction device 50 grasps the column portion 20 and bonds it to the boom boat -10- 201011140 S, and can perform the construction work in a state where the relative position is not displaced due to the shaking of the waves. For example, as shown in Fig. 3, the construction device 50 of the offshore windmill 10 has a structure in which a guide member 5 is disposed at a work position in a direction substantially perpendicular to the boom ship S, and the lower end portion is disposed in the sea. 1. At least one pair of arms 60 that slide along the guiding member 51. In the illustrated example, since the upper and lower arm portions 60 are provided, in the following description, the upper arm portion 60A and the lower arm portion 60B are classified as necessary. The arm portion 60 is provided with a grip portion 70 that can be attached to and detached from the column portion 20 which is decomposed into a plurality of portions in the axial direction. In the illustrated boom ship S, a main boom Km and a sub boom Ks are provided. The main boom Km and the auxiliary boom Ks are the nacelle 3, the rotor head 4, the wind turbine blade 5, the press block 21, the nautical column portion 22, and the offshore tower which are placed on the boom ship S by disassembling the offshore windmill 1 The component members such as the column portion 23 are used for stowage and construction work such as standing up or lifting. φ The components of the above-mentioned offshore windmill can be placed on the boom ship S for transport, or transported by other ships, and then transferred to the construction boom ship Si using the main boom • Km. The guiding member 51 is disposed, for example, in front of the boom boat S. The guide member 51 is an elongated rigid member extending in the vertical direction at a predetermined working position, and its lower end side is disposed in the sea. The guide member 51 is provided with a rotation mechanism as described below. The rotation mechanism is between the working position of the guiding member 51 shown by the solid line in FIG. 3 and the navigation position of the guiding member 51 indicated by the imaginary line, for example, the hydraulic cylinder 5 is made by -11 - 201011140. 2 means for performing a telescopic motion and changing the posture of the guiding member 51 around the fulcrum p. In other words, the guide member 51' having the rotation mechanism is rotatably mounted between the substantially horizontal navigation position in the lateral direction with respect to the boom ship S and the *working position in the substantially vertical direction. When the boom boat S moves to the construction site, it will not hinder its navigation. Instead of the above-described turning mechanism of the guiding member 51, a sliding mechanism of the first modification shown in Fig. 4 may be employed. In this modification, the guide member 51A is slidable in the vertical direction (see an arrow 54 in the drawing) by being fixedly supported by the slide mechanism portion 53 of the boom ship S. In other words, when the boom ship S sails, the lower end portion of the guide member 51A is pulled up from the sea by the slide mechanism portion 53, and the lower end of the guide member 51A can be made at a normal working position. The state of entering the water. As a result, when the boom ship S sails, the lower end portion of the guide member 51A is pulled up from the sea, or the length of the guide member 51A located in the sea is shortened, and the guide can be made at a normal working position. The lower end portion of the lead member 51A enters the state of the sea. According to the built sea-windmill, the length of the component members of the different column sections 20 is operated.

Further, in the case where the guide member 51A including the slide mechanism 53 is provided, in particular, when the entire length of the guide member 51A is long, the above-described rotation mechanism may be interposed between the slide mechanism portion 53 and the boom boat S. Instead of the above-described turning mechanism of the guiding member 51, a sliding mechanism of a second modification shown in Fig. 5 may be employed. -12- 201011140 In this modification, the guide member 51B can be changed in length in the vertical direction (see the arrow 56 in the drawing) by the telescopic mechanism 55 fixedly supported by the boom ship S. That is, when the boom ship S sails, the telescopic mechanism 55 is actuated to shorten the axial length of the guiding member 51B, and in the usual position, the telescopic mechanism 55 is actuated to increase the axial direction of the guiding member 51B.
. 向長度。結果，當吊臂船S航行時，成爲將導引構件51B 的下端部從海裏拉起的狀態，或將位於海裏的導引構件 @ 51B的長度縮短，在平常的作業位置，能成爲將導引構件 51B的下端部伸入海裏的狀態。而根據所建設的海上風車 10的塔柱部20，因應不同的塔柱部的組成構件長度等來 操作伸縮機構55的話，則能獲得最適合作業的導引構件 5 1 B的長度或位置。 藉由具備該伸縮機構55的導引構件51B，尤其在導 引構件51B的全長較長的情況等，作成與上述轉動機構及 滑動機構部53的至少其中一方組合的構造也可以。而也 φ 包含藉由使用齒輪、滑輪、或纜索等，能進行以油壓缸使 其轉動的動作的構造（沒有圖示）。 - 臂部60，例如如第6圖所示，具備有沿著上述導引構 . 件51移動的滑塊61。該滑塊61，如圖中箭頭62所示， 可朝導引構件51的軸方向（長軸方向）滑動。該臂部60 ，相對於一支導引構件51，至少設置有上下一對。 在上述臂部60設置有：可將於軸方向分解爲複數部 分的塔柱部20予以裝卸的複數組抓持部70。在圖示的構 造例子中，臂部60具備有：可改變互相的軸方向間距離 -13- 201011140 的兩組抓持部70。在以下說明中，因應需要，將位於垂直 方向上方的抓持部70稱爲上腕部70A，將位於垂直方向 下方的抓持部70稱爲下腕部70B來區分。 也就是說，具體說明上述抓持部70的構造例子的話 • ，是將抓持部主體71固定支承於臂部60而一體地移動。 . 在抓持部主體71設置有：朝導引構件51的軸方向（ 參考圖中的箭頭72)伸縮，可改變互相的軸方向間距離的 ❹ 上腕部70A及下腕部70B。 上腕部70A及下腕部70B，都由左右的一對L字型構 件所構成，具有左右的一對保持部73，該保持部73能追 隨：將塔柱部20分解後的壓塊21、海裏塔柱部22、及海 上塔柱部23的形狀。該保持部73，是相對於L字型的上 腕部70A及下腕部70B，隔介著銷部73a而被支承爲可自 由擺動。 在各保持部73，安裝有一對保持片75。將該保持片 • 75隔介著銷部74a支承爲可自由擺動。保持片75的保持 面74b作成對應於塔柱部20的圓形剖面的曲面，可因應 * 需要安裝橡膠等的防滑構件。 * 上述上腕部70A及下腕部70B，在圖中如箭頭72所 示朝與垂直方向垂直的水平方向（參考圖中的箭頭75)開 閉。結果，當將上腕部70A及下腕部70B關閉時，對於在 相對向的左右的一對保持部73之間存在的塔柱部20的分 解構件，以四個保持片74來按壓其外周面。此時，銷部 73a可自由擺動地支承著保持部73，並且銷部74可自由 -14- 201011140 擺動地支承著保持片74，所以保持片7的保持面74b，會 將壓塊21、海裏塔柱部22、及海上塔柱部23的外徑差異 予以消除而與其緊貼。所以上腕部70A及下腕部70B能夠 確實地抓持壓塊21、海裏塔柱部22、及海上塔柱部23。 當上腕部70A及下腕部70B抓持住對象的塔柱部20 . 時，將滑塊61的位置或上腕部70A及下腕部70B的軸方To the length. As a result, when the boom ship S sails, the lower end portion of the guide member 51B is pulled up from the sea, or the length of the guide member @51B located in the sea is shortened, and it can become a guide at a normal working position. The lower end portion of the lead member 51B protrudes into the sea. Further, according to the column portion 20 of the offshore wind turbine 10 to be constructed, the length of the guiding member 5 1 B which is most suitable for the operation can be obtained by operating the telescopic mechanism 55 in accordance with the length of the constituent members of the different column portions. The guide member 51B including the expansion/contraction mechanism 55 may have a structure in which at least one of the rotation mechanism and the slide mechanism portion 53 is combined, in particular, when the entire length of the guide member 51B is long. Further, φ includes a structure (not shown) that can be rotated by a hydraulic cylinder by using a gear, a pulley, or a cable. - The arm portion 60, for example, as shown in Fig. 6, is provided with a slider 61 that moves along the guiding member 51. The slider 61 is slidable in the axial direction (long axis direction) of the guiding member 51 as indicated by an arrow 62 in the figure. The arm portion 60 is provided with at least one pair of upper and lower sides with respect to one of the guide members 51. The arm portion 60 is provided with a plurality of array grip portions 70 that can be detached from the column portion 20 which is decomposed into a plurality of portions in the axial direction. In the illustrated construction example, the arm portion 60 is provided with two sets of gripping portions 70 that can change the mutual axial direction distance -13 - 201011140. In the following description, the grip portion 70 located above the vertical direction is referred to as the upper arm portion 70A, and the grip portion 70 located below the vertical direction is referred to as the lower arm portion 70B to be distinguished. In other words, when the configuration example of the grip portion 70 is specifically described, the grip portion main body 71 is fixedly supported by the arm portion 60 to be integrally moved. The grip portion main body 71 is provided with an upper arm portion 70A and a lower arm portion 70B which are expandable and contractable in the axial direction of the guide member 51 (see an arrow 72 in the drawing) to change the mutual axial direction. Each of the upper arm portion 70A and the lower arm portion 70B is composed of a pair of right and left L-shaped members, and has a pair of left and right holding portions 73 that can follow the pressing block 21 in which the column portion 20 is decomposed. The shape of the nautical column portion 22 and the offshore column portion 23. The holding portion 73 is slidably supported by the upper portion 70A and the lower arm portion 70B of the L-shape via the pin portion 73a. A pair of holding pieces 75 are attached to the respective holding portions 73. The holding piece 75 is supported to be swingable by the pin portion 74a. The holding surface 74b of the holding piece 75 is formed into a curved surface corresponding to the circular cross section of the column portion 20, and an anti-slip member such as rubber can be attached in response to the need. * The upper arm portion 70A and the lower arm portion 70B are opened and closed in a horizontal direction (refer to an arrow 75 in the drawing) perpendicular to the vertical direction as indicated by an arrow 72 in the drawing. As a result, when the upper arm portion 70A and the lower arm portion 70B are closed, the outer peripheral surface is pressed by the four holding pieces 74 with respect to the disassembling member of the column portion 20 existing between the pair of right and left pair of holding portions 73. . At this time, the pin portion 73a is rotatably supported by the holding portion 73, and the pin portion 74 is slidably supported by the holding piece 74 at a free speed of -14 to 201011140, so that the holding surface 74b of the holding piece 7 will hold the pressing block 21, the nautical mile The difference in outer diameter between the column portion 22 and the offshore column portion 23 is eliminated and adhered thereto. Therefore, the upper arm portion 70A and the lower arm portion 70B can surely grip the pressing block 21, the nautical column portion 22, and the offshore column portion 23. When the upper arm portion 70A and the lower arm portion 70B grip the tower portion 20 of the object, the position of the slider 61 or the axis of the upper arm portion 70A and the lower arm portion 70B is used.

A conventional drive mechanism such as a gear can be used. The upper arm portion 70A and the lower arm portion 70B are not limited to the gripping method that is opened and closed by the slider. For example, in the first modification shown in FIG. 7, the support by the pin portion 76 is free. The manner in which the swinging grip portion 70' is opened and closed. The illustration of the above-described swinging holding portion 73, the yoke holding piece 74, and the like is omitted in Fig. 7. Fig. 8 is a view showing a second modification of the grip portion 70 or the holding piece 74 of the arm portion 60. In the above-described configuration, the flange portion 25 is held by the grip portion 80 instead of the nip portion for providing the flange portion 25 or the like for holding the outer peripheral portion. The nip portion in this case is not limited to the flange portion 25 for connecting the exploded column portion 20, and may be a convex portion such as a pin portion. In the third modification shown in Fig. 9, a projecting portion 26 having a triangular cross section is provided in the disassembling member of the column portion 20, and a roller 91 is interposed between the convex portion 26 and the grip portion 90 -15 - 201011140. The rolling body of the etc. With this configuration, the column portion 20 is allowed to rotate relative to the grip portion 90, so that the flange bolt holes of the disassembled column portion 20 can be easily positioned. In the illustrated construction, although the column portion 20 is made rotatable, for example, the holding portions 80, 90 can be rotated relative to the arm portion 60 so as to be in contact with the column portion 20 being grasped. Body rotation is also possible. The construction device 50 of the offshore windmill 10 having the above-described structure includes φ: a guide member 51 that is attached to the working position of the boom vessel S in a substantially vertical direction and that arranges the lower end side in the sea, and is provided with The grip portion 70 that is detached from the column portion 20 in the axial direction is detached, and at least a pair of arm portions 60 that slide along the guide member 51; therefore, the column portion 20, specifically, the column portion 20, can be decomposed The constituent members (the compact 21, the nautical column portion 22, and the offshore column portion 23) after the column portion 20 are gripped by the arm portion 60 and coupled to the boom ship S. As a result, the boom member S on the sea and the disassembling member of the tower portion 20 are substantially integrated and shaken by the waves. Therefore, it is possible to carry out the construction work in a state in which the position is shifted due to the shaking of the waves. In this case, since the arm portion 60 is provided with a plurality of array grip portions 7 that can change the mutual axial direction and the distance therebetween, even if the length of the column portion 20 changes, the balance can be surely grasped. position. In the following, a construction method for constructing an offshore windmill 1 in a state in which the disassembled component of the tower portion 20 is coupled to the boom vessel S by using the above-described construction device 50 will be described based on the step diagram shown in FIG. . The construction device 50 shown in Fig. 3 is provided with the arm portion 60 shown in Fig. 6, and the sub-mount Ks of the boom ship S for -16-201011140 is omitted except for the case where necessary. In the first step, the compact 21 which is the initial decomposition component of the column portion 20 is lifted by the main boom Km of the boom ship S. At this time, if the compact 21 is decomposed into a plurality of portions, the decomposition group of the lowermost portion is hoisted. The hoisted clamp 21 is moved by the main boom Km to the guide. In the vicinity of the member 51, the lower arm portion 60B grips it. In order to facilitate the following description, in this step, the lowermost pressing block 21 gripped by the lower arm portion 60B φ is referred to as a decomposition constituent member 20a, and the members sequentially connected above are referred to as decomposition constituent members 20b, 20c, .... In other words, the tower body (decomposition component) that decomposes the compact 21, the nautical column portion 22, and the offshore column portion 23 into a plurality of portions is not particularly limited unless otherwise required. In the second step, the next decomposition constituent member 20b is placed on the compact 21 (decomposition constituent member 20a) for bonding. In the case of the decomposition component member 20b, when the compact 21 is decomposed into a plurality of portions, the second compact member is decomposed from the lower φ plane, and when the compact 21 is not decomposed, The lowermost decomposition-composition member of the nautical column portion 22 is decomposed. In the third step, the next decomposition constituent member 20c is further placed at the uppermost portion of the decomposition constituent member 20b to be joined, and the upper arm portion 60A grips the decomposition constituent member 20c. In the fourth step, the grip of the lower arm portion 60B on the disassembling component member 20a is released to be in a free state. Thereafter, the upper arm portion 60A is moved (slid) along the guide member 51 to the lower side of -17-201011140 while grasping the disassembled component member 20c. The amount of downward movement in this case is a part of the substantially divided member 20a, so that the disassembled component member 20b can be gripped by the arm portion 60B after the end of the movement. In the fifth step, the next decomposition constituent member 20d is again placed in the - portion to be combined. Then, the upper arm portion 60A releases the grasping of the disassembling component member and moves upward to grasp the decomposition component located at the uppermost portion of 20d ° φ or less 'back to the third step described above, and the third to fifth steps are The number of times required to repeat the process (the number of remaining decomposition components). As a result, the detaching members of the column portion 20 which are decomposed into a plurality of portions are integrally connected, and the upper arm portion 60A and the lower portion 60B are in a state of grasping the two positions of the upper portion. In other words, when the tower 20 is coupled to the boom boat S by the building device 50, the tower 20 is in a state in which the relative position is not displaced by the shaking of the waves. In the final step, the nacelle Φ rotor 4 is mounted on the upper portion of the completed column portion 20, whereby the assembly of the offshore windmill 10 is completed. At this time, even if the waves are affected, the boom ship S and the column portion 20 are integrally oscillated, and * the positioning operation of the mounting bolt and the bolt hole is easy. Then, when the boom boat S is to be cut away from the offshore windmill 10, the upper arm portion 60A and the lower arm portion 60B are gripped after being adjusted to a position where the offshore windmill 1 is balanced with its own weight. According to the present invention as described above, for example, when the offshore windmill is constructed in a sea area having a deep water depth, it is possible to avoid the positional displacement between the component parts and to easily assemble the upper space of the uppermost end portion of the column portion 20. That is to say, the sub-arms and columns of the lowermost 20c members are unpacked because they are 3 or received, so that they can be opened and floated, that is, -18-201011140 can also be safe in the deep sea. Smoothly build a floating offshore windmill 10 . The boom ship S having the above-described construction device 50 is not only used when the offshore windmill 10 is newly constructed, but also used for maintenance work requiring a boom, and can prevent the relative displacement of the boom ship S and the offshore windmill 10 from being caused. So non. It is often useful. In other words, the above-described construction apparatus 50 can be used as a maintenance work device when performing maintenance work, and can also be applied to a maintenance method at the time of maintenance in the above construction method. For the specific description of the maintenance work device and the maintenance method, it is only necessary to replace the construction or construction work of the construction device construction method with the maintenance or repair work. In the construction apparatus and the construction method of the present invention, and the maintenance method and the maintenance operation device, the construction device 50 is provided in the vicinity of the lower portion (sea surface) of the column portion between the boom ship S and the column portion 20 of the offshore wind turbine 1 A structure that can be combined with each other. As a result, when the offshore windmill 10 is constructed, the relative displacement of the offshore φ windmill 10 and the jib boat S can be relaxed or ignored. The present invention also includes a method of combining the structure of the offshore windmill 10 that is submerged below the sea surface with the hull of the boom ship S before the tower portion 20 or the nacelle 3 is installed. That is to say, in the present invention, by docking the boom ship S with the offshore windmill 1 ,, the same action is performed with respect to the influence of the sea waves, although it is not completely fixed with respect to the ground or the sea floor, The relative displacement of the boom boat S and the offshore windmill 10 can be eliminated. Therefore, on the deep sea at the bottom of the sea, the offshore windmill 10 can still be constructed safely and smoothly. -19- 201011140 The present invention is not limited to the above-described embodiments, and can be used for maintenance, and can be appropriately changed without departing from the spirit and scope of the invention.
