Description

[Technical Field]

[0001] The present invention relates to a scaffolding, and more particularly to a scaffolding that can be suitably applied to a wind power generation facility that has an upright tower with a cylindrical outer peripheral surface. [Background technology]

[0002] Wind power is attracting increasing attention as a form of renewable energy.

[0003] The towers of wind power generation equipment used for wind power generation are primarily constructed from steel, and require regular maintenance such as cleaning and painting. The wind turbine blades of wind power generation equipment also require regular inspections and repairs for sudden damage caused by lightning strikes. This maintenance work requires access from the outside of the wind power generation equipment tower, and from a structural standpoint, wind power generation equipment towers are increasingly being constructed as cylindrical towers.

[0004] Such cylindrical towers have no handholds on their outer periphery, so maintenance requires a large crane and a great deal of labor.

[0005] In response to this problem, a maintenance method for the wind turbine blades of existing wind power generation facilities has been proposed, which allows repair and replacement work to be carried out when the blades and their functional parts are damaged by aging or lightning strikes, without using large cranes, and with as little construction cost and time as possible (see, for example, Patent Document 1).

[0006] The maintenance method described in Patent Document 1 will be briefly described with reference to FIG.

[0007] A worker climbs onto the upper work platform 72 and moves upward using the drive unit 70 (a drive unit that can move up and down along the rack rail 52), attaching brackets 50, each having magnets 50A attached to both ends, to the outer periphery of the cylindrical tower 60 in an upward direction in sequence, while extending the rack rail 52 upward, and successively extending the rack rails 52 up to the top end of the cylindrical tower 60 of the wind power generation facility 100. The pulley-equipped band 82, which has a lifting pulley 84 loaded on the upper work platform 72, is then lifted onto the top end of the cylindrical tower 60 and wrapped around and secured.

[0008] Once the rack rails 52 have been erected up to the top end of the cylindrical tower 60, the upper work platform 72 is lowered once, and the upper work platform 72 is connected to a work scaffolding 104 (a scaffolding for inspecting and repairing the wind turbine blades 102) via a drive unit 70. The work scaffolding 104 has a shape that extends out from the connected base end in a direction perpendicular to the cylindrical tower 60, and a safety fence is attached to the top of the scaffolding plate of the work scaffolding 104.

[0009] Lifting wires 106 are attached to both the left and right ends of the tip of the work scaffolding 104, and the work scaffolding 104 can be moved to a predetermined position by a pulley 84 attached to the top end of the cylindrical tower 60 by a pulley band 82 and a winch 86 installed on the ground. Note that when moving, the scaffolding 104 moves in sync with the drive unit 70 for vertical movement, so the work scaffolding 104 is configured to be able to move without tilting.

[0010] However, in the technology described in Patent Document 1, when the work scaffolding 104 sways horizontally due to fluctuations in wind force, wind direction, etc., a worker 200 positioned on the ground around the wind power generation facility 100 responds by pulling the guy wire 108, as shown in Figure 8.

[0011] On the other hand, when the wind power generation facility 100 is located in an ocean area, it is difficult for the worker 200 to stop the swinging of the work scaffolding 104 by pulling the guy wire 108. [Prior art documents] [Patent documents]

[0024] Here, the drive device includes not only the drive mechanism parts that are directly related to driving, but also members and parts that are attached to the drive mechanism parts, move together with the drive mechanism parts, and can be considered to be part of the drive device.

[0025] Furthermore, "attached to the drive unit" includes not only the case where the object to be attached is attached in direct contact with the drive unit, but also the case where the object is attached to the drive unit via another member. [Effects of the Invention]

[0026] According to the present invention, it is possible to provide a scaffolding that can be attached to the outer surface of an upright tower having a cylindrical outer surface via magnetic force and can provide horizontal vibration prevention regardless of the size of the ground area.

[Figure 8] FIG. 1 is a perspective view showing a state in which the conventional technology (the technology described in Patent Document 1) is applied to a wind power generation facility 100. DETAILED DESCRIPTION OF THE INVENTION

[0028] Hereinafter, an embodiment of a scaffolding according to the present invention will be described in detail with reference to the drawings. Here, an embodiment of a scaffolding according to the present invention will be described with the understanding that a cylindrical tower (an upright tower with a cylindrical outer periphery) is part of a wind power generation facility. However, the application of the present invention is not limited to cylindrical towers of wind power generation facilities, and the present invention can be applied to any cylindrical tower to which a magnet can be fixed. Note that the scaffolding according to the present invention has an anti-vibration function, and the scaffolding according to the embodiment of the present invention also has an anti-vibration function, so in describing the embodiment of the present invention, the scaffolding according to the embodiment of the present invention will be referred to as scaffolding 10 with anti-vibration function.

[0029] FIG. 1 is a perspective view showing a state in which scaffolding 10 with vibration suppression functions according to an embodiment of the present invention is applied to a wind power generation facility 100, FIG. 2 is a plan view of the scaffolding 10 with vibration suppression functions according to an embodiment of the present invention as seen from above, FIG. 3 is an enlarged plan view of the base end portion 12A of the scaffolding main body 12 of the scaffolding 10 with vibration suppression functions according to an embodiment of the present invention and the surrounding area as seen from above, FIG. 4 is an enlarged side view of the base end portion 12A of the scaffolding main body 12 of the scaffolding 10 with vibration suppression functions according to an embodiment of the present invention and the surrounding area as seen from the side, and FIG.

FIG. 7 is an enlarged cross-sectional view (taken along a plane perpendicular to the pin 14B2c) schematically illustrating the connecting portion 14B2 (the connecting portion with the tension wire 18) on the upper surface of the other end 14B of the vibration-proof member 14. FIG. 8 is a perspective view showing a state in which the prior art (the art described in Patent Document 1) is applied to a wind power generation facility 100. Note that FIG. 2 omits the illustration of the hinge mechanism 14A and the drive unit 70 at one end of the vibration-proof member 14, and FIG. 3 omits the illustration of the cylindrical tower 60. In the enlarged side view of FIG. 6, the rack rail 52 and the auxiliary rail 50B are overlapping when viewed from the side and are depicted in the same position.

[0030] Scaffolding 10 with vibration suppression function according to an embodiment of the present invention is a scaffolding attached to the outer peripheral surface of a cylindrical tower 60 via the magnetic force of magnets 50A, and as shown in Figures 1 to 6, comprises a scaffolding main body 12, vibration suppression members 14, support members 16, tension wires 18, brackets 50, magnets 50A, rack rails 52, and a drive unit 70. The cylindrical tower 60 is made of a material to which the magnets can be fixed to the outer peripheral surface.

[0031] In the scaffolding 10 with vibration prevention function according to an embodiment of the present invention, the bracket 50 is provided with magnets 50A at both ends, and as shown in Figure 1, a large number of brackets 50 are attached to the outer surface of a cylindrical tower 60 at predetermined intervals in the vertical direction via the magnetic force of the magnets 50A, and a rack rail 52 is attached to the center of the bracket 50 so as to extend in the vertical direction along the outer surface of the cylindrical tower 60.

[0032] Specifically, a worker who gets on to the upper work platform 72 moves upward using the drive unit 70 (a drive unit that can move up and down along the rack rail 52), while sequentially attaching the brackets 50, each having magnets 50A attached to both ends, to the outer circumferential surface of the cylindrical tower 60 in the upward direction, and attaching the rack rail 52 to the center of the bracket 50 and extending it upward. The rack rails 52 are then sequentially extended and attached all the way to the top end of the cylindrical tower 60 of the wind power generation facility 100.

[0033] When the driving device 70 rotates the pinion 52A (see FIG. 3), the driving device 70 receives a force in the vertical direction from the rack rail 52. The force is transmitted to the base end 12A of the scaffolding main body 12 via the connecting steel member 70A (see FIGS. 3 and 6), allowing the entire scaffolding main body 12 to move up and down. As shown in FIG. 4, a vertical connecting steel member 12A1 is attached to the base end (the base end on the cylindrical tower 60 side) of the base end 12A of the scaffolding main body 12. As shown in FIGS. 3 and 4, auxiliary wheels 50C are attached to the upper and lower ends of the vertical connecting steel member 12A1 via auxiliary wheel connecting steel members 50C1 and auxiliary wheel assembly steel members 50C2. Auxiliary rails 50B are attached to both ends of the bracket 50. A plurality of auxiliary wheels 50C are provided facing each other so as to sandwich the auxiliary rail 50B. The auxiliary wheels 50C are configured to move along the auxiliary rail 50B, allowing the entire scaffolding main body 12 to move smoothly up and down.

[0034] As shown in Fig. 2, the scaffolding main body 12 has a base end portion 12A, a long portion 12B, and a hinge mechanism 12C, and the hinge mechanism 12C is provided between the base end portion 12A and the long portion 12B. The base end portion 12A of the scaffolding main body 12 is attached to the outer peripheral surface of a cylindrical tower 60 to which a magnet 50A can be fixed via the magnetic force of the magnet 50A so that the long overall shape of the scaffolding main body 12 protrudes. The hinge mechanism 12C allows the long portion 12B (the portion of the scaffolding main body 12 that is closer to the tip than the hinge mechanism 12C) to rotate relative to the base end portion 12A, and as shown in Fig. 5, the long portion 12B is configured to be able to open and close from a horizontal position to an upright position.

[0035] Both the base end 12A and the long portion 12B of the scaffolding main body 12 can be used as work scaffolding (for inspecting and repairing wind turbine blades 102, etc.), and are provided with handrails to prevent falls. When used as work scaffolding, the long portion 12B is opened horizontally (the state shown in Figures 1 and 2). When the entire scaffolding main body 12 is moved up and down by the drive device 70, the long portion 12B is closed upright and moved. By moving the scaffolding in the closed upright state, stability during up and down movement can be improved. As shown in Figure 1, a tip lifting wire 80 is connected to the tip of the scaffolding main body 12 via a pulley 84 attached to the top end of the cylindrical tower 60 by a pulley-equipped band 82.When changing the long part 12B of the scaffolding main body 12 from a horizontal state to an upright state, the tip lifting wire 80 is wound up by a winch 86 (see Figure 1) as shown in Figure 5, and when changing from an upright state to a horizontal state, the tip lifting wire 80 is wound down by the winch 86.

[0036] The anti-vibration members 14 are members that serve to prevent horizontal vibrations caused by wind or earthquakes when the long section 12B of the scaffolding main body 12 is in a horizontal position. Specifically, they serve to increase the angle that the tension wires 18 form with the scaffolding main body 12 (the scaffolding main body 12 when the long section 12B is in a horizontal position). As shown in FIG. 2, the anti-vibration members 14 are provided on both sides of the scaffolding main body 12. As shown in FIG. 3, one end of each anti-vibration member 14 is connected to both sides of the base end portion 12A via hinge mechanisms 14A, and is configured to be able to open and close from a horizontal position to an upright position. The anti-vibration members 14 are elongated rectangular plate-like bodies that are configured to be usable as scaffolding during work when in a horizontal position.

[0037] When the vibration prevention member 14 is to perform the role of preventing horizontal vibration of the scaffolding main body 12 in a horizontal position, it is opened horizontally as shown in Figures 2 and 3, and a support member 16 is connected to connecting part 14B1 on the top surface of the other end part 14B, and further connecting part 14B2 on the top surface of the other end part 14B of the vibration prevention member 14 and connecting part 12D near the center of the entire length of the scaffolding main body 12 with a tension wire 18. As shown in Figures 2 and 3, one end of the vibration prevention member 14 is attached to the base end part 12A of the scaffolding main body 12 via a hinge mechanism 14A so that its longitudinal direction forms a predetermined angle with respect to the longitudinal direction of the scaffolding main body 12 when it is opened horizontally. When the vibration-proof member 14 is opened horizontally, if the angle formed by its own longitudinal direction with respect to the longitudinal direction of the scaffolding main body 12 becomes too small (if the longitudinal direction of the scaffolding main body 12 and the longitudinal direction of the vibration-proof member 14 become close to parallel), the angle formed by the tension wire 18 and the scaffolding main body 12 (hereinafter sometimes referred to as the scaffolding main body 12 in the horizontal state) when the long portion 12B is in the horizontal state becomes small, and the effect of preventing horizontal vibration of the scaffolding main body 12 in the horizontal state becomes reduced.Therefore, it is preferable that the angle formed by the longitudinal direction of the scaffolding main body 12 in the horizontal state and the longitudinal direction of the vibration-proof member 14 in the horizontal state be a predetermined angle or more, specifically, for example, 45° or more.

[0038] The support members 16 are rod-shaped members, and as shown in FIG. 2, are provided on both sides of the scaffolding body 12. Each support member is equipped with a magnet 16A at one end, and the one end is detachably fixed to the outer circumferential surface of the cylindrical tower 60 via the magnetic force of the magnet 16A. The support members 16 are attached to the outer circumferential surface of the cylindrical tower 60 via the magnetic force of the magnet 16A so that their elongated overall shape protrudes. The other end of the support member 16 is connected to a connector 14B1 provided on the upper surface of the other end 14B of the anti-vibration member 14. The connector 14B1 of the anti-vibration member 14 can be a mechanism capable of gripping the rod-shaped support member 16. Specifically, for example, a center-hole clamp can be used, which can be set toward the radial center of the cylindrical tower 60 and allows the gripping position of the rod-shaped support member 16 to be changed.

[0039] The tension wires 18 are wire members stretched between the connecting portion 14B2 of the other end 14B of the anti-vibration member 14 and the connecting portion 12D (a portion at least a predetermined distance from the outer circumferential surface of the cylindrical tower 60) near the center of the entire length of the scaffolding body 12, and as shown in Figure 2, there are two tension wires in total, one on each side of the scaffolding body 12, and they transmit the force caused by horizontal vibrations that occur in the horizontally positioned scaffolding body 12 as tension to the other end 14B of the anti-vibration member 14. If the angle between the tension wires 18 and the longitudinal direction of the horizontally positioned scaffolding body 12 becomes smaller, the horizontal vibration-proofing effect on the horizontally positioned scaffolding body 12 decreases, so it is preferable that the angle between the tension wires 18 and the longitudinal direction of the horizontally positioned scaffolding body 12 be equal to or greater than a predetermined angle, specifically, for example, 20° or greater. Furthermore, if the position of the connecting portion 12D is too close to the outer peripheral surface of the cylindrical tower 60, the horizontal vibration-proofing effect on the horizontal scaffolding body 12 will be reduced, so the connecting portion 12D should be positioned at a predetermined distance or more from the outer peripheral surface of the cylindrical tower 60.However, from the perspective of preventing the angle between the tension wire 18 and the longitudinal direction of the horizontal scaffolding body 12 from becoming too small, and from the perspective of the maintenance work range and maintenance efficiency, it is preferable to position the connecting portion 12D near the center of the overall length of the scaffolding body 12.

[0040] As shown in FIG. 7, the connecting portion 14B2 of the anti-vibration member 14 is composed of two opposing steel members 14B2a, an assembly steel member 14B2b, a pin 14B2c, a connecting steel member 14b2d, a threaded steel rod 14B2e, and a nut 14B2f. (Since FIG. 7 is a cross-sectional view (a cross-sectional view cut along a plane perpendicular to the pin 14B2c), only one opposing steel member 14B2a is shown.) The two opposing steel members 14B2a are fixed to the assembly steel member 14B2b by welding with a predetermined gap between them. The two opposing steel members 14B2a have through holes at corresponding positions, and the pin 14B2c passes through these through holes. The tension wire 18 has its tip fastened in a ring shape by a fastener 18A, and the pin 14B2c passes through this ring-shaped connecting portion. A threaded steel rod 14B2e is welded to the opposite surface of the assembly steel material 14B2b (the surface opposite to the side to which the counter steel material 14B2a is welded). A through hole is provided in the connecting steel material 14B2d, through which the threaded steel rod 14B2e is inserted, and the connecting steel material 14B2d is attached to the upper surface of the other end 14B of the vibration prevention member 14. A nut 14B2f is attached to the tip of the threaded steel rod 14B2e that has passed through the through hole in the connecting steel material 14B2d, and by rotating the nut 14B2f, the distance x between the assembly steel material 14B2b and the connecting steel material 14B2d can be adjusted, and by adjusting the distance x, the tension of the tensioning wire 18 can be adjusted. 7, the connection portion at the tip of the tension wire 18 is depicted as being fastened in a ring shape with fastener 18A, but the connection portion of the tension wire 18 can be designed appropriately depending on the tension applied to the tension wire 18, such as by using a thimble, depending on the tension applied to the tension wire 18. The material, diameter, etc. of the tension wire 18 should also be appropriate depending on the tension applied and other conditions.

[0041] In addition, the tip of the tension wire 18 on the connection portion 12D side is in the same ring-shaped form as shown in Figure 7 (the tip is fastened in a ring shape with fastener 18A), and a pin (not shown) of connection portion 12D is inserted through this ring-shaped connection portion, thereby connecting the tension wire 18 at connection portion 12D.

[0042] Since the scaffolding 10 with vibration suppression function according to the embodiment of the present invention is configured as described above, the force caused by horizontal vibrations occurring in the scaffolding main body 12 in a horizontal state is transmitted to the cylindrical tower 60 via two routes. (Scaffolding body 12 in horizontal position) → (tension wire 18) → (vibration prevention member 14) → (base end portion 12A) → (vertical connecting steel member 12A1 and connecting steel member 70A) → (bracket 50) → (cylindrical tower 60) The force caused by horizontal vibration is transmitted in this order, and in the second route, (Scaffolding body 12 in horizontal position) → (tension wire 18) → (vibration prevention member 14) → (support member 16) → (cylindrical tower 60) The force due to horizontal vibration is transmitted in this order, thereby reducing the horizontal vibration of the scaffolding main body 12 in a horizontal state.

[0043] As mentioned above, in the prior art (the technology described in Patent Document 1), as shown in Figure 8, when the work scaffolding 104 sways horizontally due to fluctuations in wind force, wind direction, etc., workers 200 positioned on the ground around the wind power generation facility 100 respond by pulling on the guy wires 108. However, the scaffolding 10 with vibration suppression function according to an embodiment of the present invention can transmit the force caused by horizontal vibrations occurring in the horizontal scaffolding main body 12 to the cylindrical tower 60 via the two routes mentioned above without human intervention, and can reduce the horizontal vibrations occurring in the horizontal scaffolding main body 12 without human intervention. This makes it possible to reduce the horizontal vibrations occurring in the horizontal scaffolding main body 12 regardless of the size of the ground area.

[0044] As mentioned above, one end of the anti-vibration member 14 is connected to the base end 12A via the hinge mechanism 14A, and is configured to be able to open and close from a horizontal state to an upright state, and is set to the horizontal state when reducing horizontal vibrations that occur in the horizontal scaffolding main body 12, but can also be set to an upright state. When the entire scaffolding main body 12 is moved up and down by the drive device 70, not only is the long section 12B of the scaffolding main body 12 closed to an upright state, but the anti-vibration member 14 is also closed to an upright state, thereby improving stability during movement.
