An embodiment of the present invention will be described with reference to the drawings.

[1. First Embodiment]
In the first embodiment, a rack 30 with a jack for assembling, moving, and storing the tower 110 of the offshore wind turbine will be described. The offshore wind turbine 100 includes a tower 110 shown in FIG. 2, a nacelle (not shown), and blades (not shown). Note that the tower 110 is a tower-like structure having a height of, for example, about 100 m.

The tower 110 is composed of four tower members 111A, 111B, 111C, and 111D divided in the height direction (hereinafter, the four tower members may be collectively referred to as the tower member 111). The tower member 111A is the uppermost tower member, the tower member 111B is the second tower member from the top, the tower member 111C is the third tower member from the top, and the tower member 111D is from the top. This is the fourth (bottom) tower member.

The nacelle houses bearings, a power generator, and the like. The power generator includes a gearbox that increases the rotation speed of the blades, a generator (induction generator, synchronous generator, etc.), and a monitoring device that monitors the operating status of the offshore wind turbine 100 and the like. The nacelle is attached to the top of the uppermost tower member 111A. Also, a plurality of blades are attached to the nacelle.

Next, the pedestal 10 will be described with reference to FIG. The pedestal 10 functions as a pedestal on which heavy objects such as a rack with a jack, a tower 110, and a crawler crane, which will be described later, are placed in the port. The pedestal 10 is made of steel and is installed on the ground to widely distribute the load from the pedestal with jacks and the crawler crane to the ground. In addition, the pedestal 10 has a lattice shape in plan view, and an airbag jack (not shown) is installed in each gap 11 of the lattice, so that the entire inner surface of the gap 11 can be uniformly distributed. In addition, the air bag jack is connected to a monitor (not shown) that monitors the air pressure and a control device (not shown) that controls the air pressure (even if these are integrated devices Good), if the ground subsides and the air pressure drops, the subsidence of the pedestal 10 can be suppressed by increasing the air pressure. It should be noted that the surface pressure may be increased by pouring sand or concrete into the gap 11 . Alternatively, the gap 11 for installing the airbag jack and the gap 11 for pouring sand or concrete may be arranged so as to be evenly dispersed.

Next, the rack 30 with jack used for assembling, moving, and storing the tower 110 will be described with reference to FIGS. 4 to 8. FIG.

A mount 30 with a jack is constructed on the base 10 with a steel mat sandwiched between the base 10 and the base 10 . In other words, the foundation of the mount 30 with jack is not provided directly on the ground. The rack 30 with a jack includes a jack 33 that lifts the tower member 111 and the tower 110 with a strand, a cart 20 that moves the tower member 111 and the tower 110, and a support that supports the abdomen of the tower 110 to prevent lateral swing and overturn. a support 50;

As shown in FIG. 5, the jacked mount 30 includes a mount main body 30A and a jack-up mount 30B. The gantry main body 30A is constructed on one side (left side in FIG. 4, right side in FIG. 110 is moved and stored in a standing posture. The jack-up gantry 30B is constructed at a position facing the most land-side portion (span) of the gantry body 30A. Two jacks 33 used for assembling the tower member 111 are provided on the upper beams of the jack-up frame 30B and the land-side portion (span) of the frame main body 30A. 5, the area surrounded by the four jacks 33 is called an assembly area 201, and the area below it is called a storage area 202. As shown in FIG. In the present embodiment, the height of the pedestal in the assembly area 201 is 13 (see FIG. 12), and the height of the pedestal in the storage area 202 is 10 (see FIG. 4, etc.). In the drawing, illustration of the frame of the assembly area 201 is omitted.

In the assembly area 201, the tower 110 is assembled by successively adding tower members 111B, 111C, and 111D in the second and subsequent stages from the top under the uppermost tower member 111A.

The tower 110 assembled in the assembly area 201 is supported by the support 50 and placed on the cart 20 to move along the moving path M. Then, the assembled tower 110 is stored in a storage area 202 extending from the assembly area 201 to the front end of the gantry main body 30A. When the tower 110 is unloaded from the storage area 202, the tower 110 is unloaded in order from the tip side of the gantry main body 30A. In the example of FIG. 5, six towers 110 can be stored in the storage area 202, but the number of towers 110 that can be stored can be increased or decreased according to the environment in which the gantry main body 30A is installed.

In this way, in the rack 30 with jacks, the assembly area 201 and the storage area 202 are arranged in order from the land side to the sea side, and since the storage area 202 is arranged on the sea side, the storage area 202 is located on the sea side. Work efficiency is high when loading the tower 110 on a ship or the like.

Each tower 110 stored in the storage area is supported by supporting supports 50 for preventing overturning.

Next, the supporting support 50 will be described with reference to FIGS. 6 to 8. FIG. As shown in FIG. 7, the support 50 has an upper frame 51 and a lower frame 52, which are vertically connected to each other by connecting members 59. As shown in FIG. As shown in FIG. 6, the upper frame 51 has a U-shape in plan view, is composed of a first frame member 51A, a second frame member 51B and a third frame member 51C, and is open on the opposite side of the gantry main body 30A. It is

A fixed support member 54A is installed between the first frame member 51A and the second frame member 51B, and a fixed support member 54B is installed between the second frame member 51B and the third frame member 51C. The fixed support member 54A and the fixed support member 54B reinforce the upper frame 51 and support the tower 110 by coming into contact with the side surface of the abdomen (center of gravity or its vicinity) of the tower 110 .

A movable support member 55A and an arm 56A are provided on the upper surface of the first frame member 51A. One end of the movable support member 55A is rotatably fixed near the central portion of the first frame member 51A, and the other end of the movable support member 55A abuts on the side surface of the abdomen of the tower 110 to support the tower 110. It has come to support. One end of the arm 56A is rotatably fixed to the end of the first frame member 51A, and the other end of the arm 56A is rotatably fixed to the other end of the movable support member 55A. Similarly, a movable support member 55B and an arm 56B are provided above the third frame member 51C. As a result, the movable support members 55A and 55B open and close the open portion of the U-shaped upper frame 51 in plan view (see FIG. 15 for the state in which the movable support members 55A and 55B are open). The movable support members 55A and 55B are fixed in contact with the side surface of the abdomen (center of gravity or its vicinity) of the tower 110 in a state where the open portion of the U-shape in plan view is closed, thereby supporting the tower 110. To support. For fixing the movable support members 55A and 55B, for example, fixing by bolts and nuts or fixing by pins can be adopted.

The lower frame 52 may be provided with fixed support members 54A and 54B, movable support members 55A and 55B, and arms 56A and 56B to support the tower 110 in the same manner as the upper frame 51. Further, illustration of these members is omitted in FIGS. 7, 8, and the like.

As shown in FIG. 7, a plurality of upper running rail support portions 34 and a plurality of lower running rail support portions 36 are provided on the plurality of struts 31 of the gantry body 30A, respectively. 35 and a lower running rail 37 are installed. H steel can be used for the upper running rail 35 and the lower running rail 37 .

A chill tank 60 is fixed to the bottom surface of the second frame member 51B. Further, when the support 50 is moved, the driving device main body 61 (see FIG. 8) is joined (by pin joining or the like) to the bottom surface of the second frame member 52B. A chill tank 41 is fixed to the bottom surface of the drive device main body 61 , and jacks 40 are fixed to the front and rear of the drive device main body 61 .

The jack 40 pulls a wire 62 installed along the moving direction (front-rear direction) of the gantry body 30A, whereby the chill tank 60 runs on the upper running rail 35 and the chill tank 41 runs on the lower running rail 37. run above. Thereby, the supporting support 50 can be moved along the moving path M. As shown in FIG. Since the support 50 is freed from the gantry main body 30A by releasing the connection with the drive device main body 61, the chill tank 60 can be easily removed from the gantry main body 30A by lifting it upward enough to remove it from the upper running rail 35. can be removed.

As shown in FIG. 1, in the conventional jack-equipped platform 500, the tower T is constructed on both the left and right sides of the movement path M, so even if a force acts to overturn the tower T in the left-right direction, it can easily be lifted. However, as shown in FIG. It is necessary to have a structure that can sufficiently support when Therefore, a mechanism for preventing the tower 110 from overturning in the horizontal direction will be described below.

First, with reference to FIG. 7, a mechanism for supporting the tower 110 when (the head side of) the tower 110 is overturned toward the gantry main body 30A (left side in FIG. 7) will be described.

Sliding contact portions 53 are provided on extensions of the first frame member 51A and the third frame member 51C of the upper frame 51 toward the gantry main body 30A (see FIG. 6). On the other hand, two horizontal rails 38 are installed on the gantry main body 30A along the moving direction of the tower 110 at a height corresponding to the sliding contact portion 53 . The sliding contact portion 53 and the horizontal rail 38 are in sliding contact with each other, and when a force acts to cause the tower 110 to overturn toward the gantry main body 30A, the sliding contact portion 53 contacts the horizontal rail 38 to prevent overturning. H steel can be used for the horizontal rails 38 . Further, in the first embodiment, the sliding contact portion 53 is slidably contacted with the horizontal rail 38. However, when the two are separated and a force acts to cause the tower 110 to fall toward the gantry main body 30A side, the sliding contact portion 53 is displaced. It may be in contact (in this case, since the sliding contact portion 53 does not slide on the horizontal surface, it becomes a contact portion).

Next, a mechanism for supporting the tower 110 when (the head side of) the tower 110 is overturned on the opposite side (the right side in FIG. 7) of the gantry main body 30A will be described.

An upper bracket 57 is provided on the bottom surface of the sliding contact portion 53 and at a position corresponding to the gantry main body 30A side of the upper running rail 35 . On the other hand, a lower bracket 58 is provided on the bottom surface of the third frame member 52C. A gap C is designed between the lower bracket 58 and the lower running rail support portion 36 . When the tower 110 is overturned to the opposite side of the gantry main body 30A, the upper bracket 57 is caught on the upper running rail 35 from the upper side on the gantry main body 30A side, and the upper running rail 35 is pulled downward from the upper running rail 35. The lower bracket 58 abuts on the lower running rail support portion 36 installed on the side from the opposite side of the gantry body 30A. As a result, the tower is prevented from overturning even in the case where the tower 110 overturns on the opposite side of the gantry main body 30A.

By the way, as shown in FIG. 9, when the support 50 does not move (when it is stopped), both the sliding contact portions 53 are fixed by the fixed hooks 63 attached to the column 31, so that the gantry main body It is fixed at 30A.

As shown in FIGS. 10A and 10B, the fixed hook 63 includes a mounting portion 63A, a first hook portion 63B, a second hook portion 63C and a pin 63P. The attachment portion 63A has an opening to be attached to the post 31 and a pin hole for joining the first hook portion 63B and the second hook portion 63C with a pin 63P. As shown in FIGS. 10(D) and 10(E), the first hook portion 63B and the second hook portion 63C have an upper and lower two-piece structure, and are rotatably attached to the attachment portion 63A by a pin 63P. However, when the sliding contact portion 53 is fixed, it is structured to be locked so as not to rotate. 10(A) is a diagram showing a state in which the sliding contact portion 53 is released, and FIGS. 10(B) to 10(E) show a state in which the sliding contact portion 53 is fixed. It is a diagram.

The drive 95 comprising the jack 40 , chill tank 60 and drive body 61 can be separated from the support support 50 . At this time, as shown in FIGS. 11A and 11B, the load of the support 50 is received by the jack 64 and the support 50 is lifted slightly to release the joint between the driving device 95 and the second frame member 52B. After that, the driving device 95 is moved to separate them. By making the support 50 and the drive device 95 separable in this way, one drive device 95 can be used for a plurality of support supports 50 . For example, when one support 50 is moved to a predetermined position, only the driving device 95 is cut off, moved to another support 50 and joined, and another support 50 is moved. The support 50 separated from the driving device 95 is fixed to the gantry main body 30A using the fixing hook 63. As shown in FIG.

Further, as described above with reference to FIG. 7, the upper bracket 57 is hooked to the upper running rail 35 from above on the gantry main body 30A side. A member for pressing the support 50 from above is not arranged, or only a light member that can be easily removed is used. By separating the driving device main body 61 from the bottom surface of the support 50, there is no longer anything to tie it to the gantry main body 30A. can.

[2. Second Embodiment]
Next, a second embodiment will be described. In the gantry 30 with jacks of the first embodiment, the gantry body 30A is constructed on one side of the movement path M of the tower 110, but in the gantry 30 with jacks of the second embodiment, in addition to the gantry body 30A, As shown in FIG. 13, along the moving path M, an auxiliary platform 210 constructed on the side opposite to the platform main body 30A is included. The auxiliary gantry 210 includes support members 211 that support the tower 110 that has moved in the direction perpendicular to the movement path M from the gantry main body 30A side, and serves as a storage place for the tower 110 or a temporary evacuation place for waiting for inspection. as a role.

As shown in FIG. 13, in the gantry main body 30A, one tower 110 can be assembled in the assembly area 201, and six towers 110 can be stored in the storage area 202. As shown in FIG. In addition, the auxiliary gantry 210 can store the tower 110 at a position facing the tower 110 stored in the storage area 202 of the gantry body 30A. However, the auxiliary frame 210 does not have a portion (span) corresponding to the position facing the tip of the movement path M of the tower 110 (the position facing the tower 110A in FIG. 13). That is, since the auxiliary platform 210 is not constructed on the left side of the tower 110A in FIG. It can be carried out to the sea side.

By the way, for example, the tower 110 assembled in the assembly area 201 is shipped after passing a predetermined inspection. At this time, if the inspection fails, the tower 110 cannot be moved until the tower 110 passes the re-inspection, and the work of assembling the tower 110 is delayed.

Therefore, for example, if the tower 110 in the assembly area 201 fails the inspection, the tower 110 is first moved to the storage area 202 as shown in FIG. 14, and then assisted as shown in FIGS. By retreating to the pedestal 210, it is possible to prevent the failed tower 110 from obstructing the movement path M of the subsequent tower 110 and delaying the assembly work of the tower 110.例文帳に追加16, members such as the lower frame 52 and the connecting member 59 are omitted.

As shown in FIGS. 15 and 16, when the tower 110 is retracted to the auxiliary platform 210, the tower 110 is moved 90 degrees to the right of the normal moving direction (moving direction during retraction). Therefore, in the second embodiment, the carriage 20 on which the tower 110 is placed and the transport frame 87 are simultaneously moved in the direction in which the auxiliary platform 210 is located, thereby safely retracting the tower 110 . The transport frame 87 supports the tower 110 instead of the support 50 when moving the tower 110 to the auxiliary platform 210 .

Next, as shown in FIGS. 17(A) and 17(B), the trolley 20 is arranged so that it can move in the normal movement direction (front-rear direction) and in the shunting movement direction (left-right direction). of rails 65-68 are laid.

Next, the flow of assembling, moving, storing, and carrying out the tower of the offshore wind turbine 100 will be described.

First, the tower members 111 are brought into the assembly area 201 to assemble the tower 110 . For example, a crawler crane (not shown) arranged on the pedestal 10 places the tower member 111 transported by a transport vehicle (not shown) on the trolley 20 arranged in the assembly area 201 . The cart 20 is conveyed by the cart conveying device 80 to move the tower 110 assembled in the assembly area 201 to the storage area 202 . Flanges are formed on the four sides of the upper surface of the carriage 20 to prevent the tower 110 from overturning during movement.

In the assembly area 201, a plurality of tower members 111 are assembled. Specifically, the tower member 111 is assembled by sequentially adding the second and subsequent tower members 111 under the uppermost tower member 111A.

As a result, the force applied to the lower frame 52 toward the gantry main body 30A can be received by the lower travel rail support portion 36 via the lower bracket 58 .

Furthermore, the wheels of the chill tank 60 joined to the upper frame 51 of the first and second embodiments run on the upper running rail 35 . As a result, the member on which the chill tank 60 travels and the member on which the upper bracket 57 is hooked from the gantry main body 30A side can be used together.

Furthermore, the wheels of the chill tank 41 joined to the lower frame 52 of the first and second embodiments run on the lower running rail support portion 36 . As a result, the member on which the chill tank 41 travels and the member on which the lower bracket 58 abuts from the opposite side of the gantry main body 30A can be used together.

Furthermore, the upper frame 51 of the first and second embodiments surrounds and supports the tower 110, and by moving the movable support members 55A and 55B, the upper frame 51 moves toward the opposite side of the movement path M to the gantry main body 30A. The side can be opened and closed. As a result, the tower 110 can be easily carried out from the support 50 from the side opposite to the gantry main body 30A side. Moreover, it is not necessary to lift the support 50 above the tower 110 when removing the support 50 from the gantry body 30A.

Furthermore, the gantry main body 30A of the first embodiment and the second embodiment includes a fixing hook 63 for fixing the support 50 to the gantry main body 30A. As a result, when the tower 110 and the support 50 do not need to be moved (for example, when stored), the support 50 can be fixed to the gantry main body 30A, and the tower 110 can be stably supported.

Furthermore, the gantry main body 30A, the jack-up gantry 30B, and the auxiliary gantry 210 of the first and second embodiments are the mat 93 and just below the mat 93, the upper surface of which is coated with a lubricant. A (Steel Use Stainless) plate 94 (an example of a “seismic isolation means”) is provided. As a result, the bottom surface of the mat 93 and the top surface of the SUS plate 94 slide when shaking due to an earthquake or the like occurs.

Furthermore, the gantry main body 30A of the first embodiment and the second embodiment includes a carriage 20 on which the tower 110 is placed, and first and second front and rear rails 65 and 66 laid on the moving route M and on which the carriage 20 travels.

Thereby, the carriage 20 can be moved in the direction of the moving path M and in the direction perpendicular to the direction.

Furthermore, the auxiliary gantry 210 of the second embodiment is constructed along the movement path M on the opposite side of the gantry main body 30A across the movement path M. A support member 211 (an example of a “support means”) is provided to support the tower 110 that has moved in the perpendicular direction. As a result, the tower 110 on the moving route M can be temporarily stored by the auxiliary frame 210.

Furthermore, the auxiliary trestle 210 of the second embodiment is not constructed at a position facing the tip of the moving path M of the tower 110 in the trestle main body 30A. That is, the auxiliary frame 210 is not constructed at the position facing the tower 110A in FIG. 13, leaving a space for one span. As a result, when carrying out the tower 110A, it can be carried out after being taken out to the auxiliary stand 210 side. After carrying out the tower 110A, it is necessary to remove the trolley 20 and the support 50 from the gantry main body 30A and carry them to the starting point of the moving route M. Being empty makes it easy to remove the carriage 20 and the support 50 from the gantry main body 30A. That is, working efficiency can be improved. In the case of the conventional jacked stand 500 shown in FIG. 1, it was necessary to remove the guide slider corresponding to the support support 50 of the present application through the stand or to pass the dolly through the stand. was bad. The auxiliary mount 210 of the second embodiment can solve these problems.

As a result, the tower 110 can be safely moved along the movement route M.

[3. Modification]
When the tower 110 is installed offshore, a monopile buried in the seabed and a transition piece (an example of a “windmill component”) connected above the monopile are constructed at the installation position.

As shown in FIG. 24 , the transition piece 300 has a tower 301 , a flange 302 and an inspection table 303 . The tower-like part 301 has a cylindrical shape, and the upper part of the monopile is partially inserted from the lower surface side and fixed, so that the transition piece 300 is fixed on the sea. A flange 302 is formed on the upper surface of the tower-like portion 301 and is flange-joined to the lower end portion of the tower 110 . An inspection table 303 is formed by a portion of the flange 302 protruding outward.

The transition piece 300 is loaded on the SEP ship from the port and transported to the installation position. Therefore, a transition piece gantry is constructed by miniaturizing the gantry main body 30A according to the size of the transition piece 300, and the transition piece 300 is moved and stored. At this time, the gantry main body 30A and the pillars and beams of the gantry main body 30A and the transition piece pedestal are used as common pedestal parts, so that the gantry main body 30A can be constructed from a plurality of transition piece pedestals, or the gantry main body 30A can be divided into a plurality of parts. You can build a pedestal for the transition piece.

For example, as shown in FIG. 25, a transition piece cradle 320 can be constructed in a port to store the transition piece 300 in a standing position. The crane 311 of the SEP ship 310 sequentially loads the transition piece 300 on the sea side onto the SEP ship 310 and transports it out to sea. When the transition pieces 300 are transported, the transition pieces 300 are moved one by one from the land side to the sea side by the transition piece mount 320 and stored until they are loaded onto the SEP ship 310 .

As shown in FIGS. 26 to 28, the transition piece pedestal 320 has the same configuration as the pedestal main body 30A described above, and is a smaller version of the pedestal main body 30A. The transition piece gantry 320 can be constructed from some of the pillars and beams used in the gantry body 30A, and a plurality of transition piece cradles 320 can be constructed from one gantry body 30A. That is, the pillars, beams, and the like can be shared by the gantry main body 30A and the gantry 320 for the transition piece. Depending on the size of the transition piece 300, the support 50 for the tower 110 and the carriage 20 can also be shared. If the sizes are different, the support 50 for the transition piece 300 and the carriage 20 are prepared.

As shown in FIGS. 26 and 27, the number of pillars and beams of the transition piece stand 320 can be changed as appropriate. Therefore, by appropriately changing the shape of the transition piece gantry 320 according to the number of columns and beams required for one gantry main body 30A, it is possible to mutually disassemble/assemble without excessive columns and beams. be able to

When constructing an offshore wind turbine, the process of assembling and storing the tower 110 using the frame main body 30A and the process of assembling and storing the transition piece 300 do not overlap in terms of timing, so common parts are used. The gantry main body 30A and the gantry 320 for the transition piece can be constructed.

According to the transition piece stand 320 , the transition piece 300 can be stably moved by the carriage 20 and the support 50 or stably stored by using the support 50 .
