Hereinafter, an embodiment of a method for installing a ferris wheel according to the present invention will be described with reference to the drawings.
As shown in FIGS. 1 and 21, first, the column foundation 1 and the stay wire fixing foundation 2 are embedded in the ground G, and the column 3 is erected on the column foundation 1. A plurality of (four in this embodiment) stay wires 4 are extended from the top toward the stay wire fixing base 2.
In addition, as shown in FIG. 21, a rail 5 is laid on the ground G located between one column 3 and the other column 3, and a work cart 6 (work cart 7 is attached to the work cart 7 depending on the work situation). The one before attaching the spoke wire drum 23, the work scaffold 24, and the hydraulic jack 25 (that is, the one having only the carriage 22) or the work carriage 7 moves on the rail 5.

As shown in FIG. 22, a shaft portion 8 and a spindle portion 9 are provided at the top of the column 3, and a rotating scaffold 10 is provided on the spindle portion 9.
Further, an intermediate scaffold 11 is provided above the intermediate position in the height direction of the column 3, and a lower scaffold 12 is provided below the intermediate position in the height direction of the column 3. The intermediate scaffold 11 and the lower scaffold 12 are located at a position suitable for assembling (connecting) or disassembling the temporary support member 13 divided into a plurality of parts (three parts in this embodiment), that is, the joint of the temporary support member 13. It is installed at the height where is located.
The inner ends of the fixed beams 12a that support the lower scaffolding 12 are clamped with rails 14a provided on both side surfaces of the rim 14 being installed, and the rim 14 is unidirectional with the rails 14a clamped. A propulsion device 15 with a clamp mechanism to be pushed is attached.
In addition, a horizontal reaction force support oblique column 30 is installed to smoothly transmit the horizontal reaction force acting on the propulsion device 15 with the clamp mechanism to the ground.

  When the standing of the column 3 having such a configuration on the column base 1 is finished and the four stay wires 4 are extended from the top of the column 3 toward the stay wire fixing base 2, the next step is as follows. The first temporary support member 13 is attached to a predetermined position of the spindle portion 9. Since the temporary support member 13 is divided into three parts in the present embodiment, first, a member located on the innermost side in the radial direction (that is, a member located closest to the spindle portion 9) is first replaced with the spindle portion 9. It will be attached at a predetermined position. The member located on the innermost side in the radial direction of the temporary support member 13 is placed on the work carriage 6 and moves on the rail 5. A winch extending vertically downward from a winch 19 through a pulley 20 installed on the ground G and a pulley (not shown) attached to the rotary scaffolding 10 at one end of the temporary support member 13 that has moved to a predetermined position. One end of the wire 21 is attached, and the winch wire 21 is wound up by the winch 19, whereby the temporary support member 13 is suspended (see FIG. 1). When the winch wire 21 is further wound by the winch 19 from this state, one end portion of the temporary support member 13 reaches a predetermined position of the spindle portion 9, and the one end portion of the temporary support member 13 and the spindle portion 9 are rotated by the rotary scaffold 10. Are, for example, bolted. The work carriage 6 is further moved on the rail 5 in the traveling direction from the time when one end portion of the temporary support member 13 is separated from the work carriage 6 until the other end portion of the temporary support member 13 is separated from the work carriage 6. Thus, the temporary support member 13 is prevented from shaking at the moment when the other end portion of the temporary support member 13 is separated from the work carriage 6.

  In the same manner, a member positioned in the middle of the temporary support member 13 is suspended, and the other end portion of the temporary support member 13 previously attached to the intermediate scaffold 11 and one end portion of the member positioned in the middle are, for example, After the bolts are joined, the member located on the outermost side in the radial direction is suspended, and the other end portion of the member located in the middle of the temporary support member 13 previously attached to the lower stage scaffold 12 is the most in the radial direction. One end of the member located outside is bolted, for example, and the first temporary support member 13 is attached to the spindle 9 (see FIG. 2). At this stage, the brake truss B is attached to the column base 1.

Next, as shown in FIG. 2, one of the rims 14 divided into a plurality of pieces (in the present embodiment, twenty-eight divisions) is placed on the work carriage 7 and moves on the rail 5.
As shown in FIG. 24, the work cart 7 has a spoke wire drum 23 installed on the cart 22 and a plurality (12 in this embodiment) on the work scaffold 24 installed on the cart 22. The hydraulic jack 25 is arranged. The spoke wire drum 23 accommodates a spoke wire 26 (see FIG. 4) that is stretched between the spindle portion 9 and the rim 14. The hydraulic jacks 25 can be operated separately. Each hydraulic jack 25 is controlled so that a predetermined (constant) load calculated in advance is applied.

As shown in FIG. 3, the rim 14 on the work carriage 7 that has moved to a predetermined position is further jacked up by the hydraulic jack 25, and the other end portion of the member that is located on the outermost side in the radial direction of the temporary support member 13. And the one end part of the rim | limb 14 is bolt-coupled, for example.
When the connection between the other end of the member located on the outermost side in the radial direction of the temporary support member 13 and the one end of the rim 14 is completed, the work carriage 7 is gradually moved from the position of FIG. 3 to the position of FIG. The temporary support member 13, the rim 14, and the spindle portion 9 are slightly rotated in one direction (clockwise in FIG. 4). At this time, the connection point (joining point) between the temporary support member 13 and the rim 14 advances in an arc shape having a radius from the rotation center of the spindle portion 9 to the connection point between the temporary support member 13 and the rim 14. As described above, the height of each hydraulic jack 25 is automatically adjusted.
Then, as shown in FIG. 4, once the first spoke wire 26 can be stretched, the movement of the work carriage 7 is temporarily stopped, and the first spoke wire 26 is stretched between the spindle portion 9 and the rim 14.

  When the extension of the spoke wire 26 is completed, the work carriage 7 is gradually moved from the position shown in FIG. 4 to the position shown in FIG. 5, and the temporary support member 13, the rim 14 and the spindle portion 9 are slightly moved in one direction (in FIG. Direction). Also at this time, the connection point between the temporary support member 13 and the rim 14 proceeds in an arc shape having a radius from the rotation center of the spindle portion 9 to the connection point between the temporary support member 13 and the rim 14. The height of each hydraulic jack 25 is automatically adjusted. When the work carriage 7 reaches the position shown in FIG. 5 (that is, when the other end of the rim 14 is positioned between the columns 3 and 3), the movement of the work carriage 7 is stopped and the left and right rims 14 are connected. The receiving portion provided at the tip of the brake truss B is engaged with the pipe-shaped horizontal member 14b (see FIG. 23) (see FIG. 6), and the temporary support member 13, the rim 14 and the spindle portion 9 are others. This prevents rotation in the direction (counterclockwise in FIG. 5). At this time, by operating the clamp mechanism 16 of the propulsion device 15 with the clamp mechanism, rotation of the temporary support member 13, the rim 14, and the spindle portion 9 in the other direction is prevented double. . Then, the work carriage 7 is retracted to the outside (right side in FIG. 6) from the workstation immediately below the spindle portion 9.

A second rim 14 of the rims 14 divided into twenty-eight is placed on the retracted work carriage 7. The work carriage 7 on which the second rim 14 is mounted moves on the rail 5 as in FIG. 2 (see FIG. 7). At this time, the engagement between the horizontal member 14b and the receiving portion provided at the tip of the brake truss B is released.
As shown in FIG. 8, the rim 14 on the work carriage 7 that has moved to a predetermined position is further jacked up by a hydraulic jack 25, and the other end of the first rim 14 and the second rim 14. For example, a bolt connection is made to one end portion of each.
When the connection between the other end of the first rim 14 and the one end of the second rim 14 is completed, the work carriage 7 is gradually moved from the position of FIG. 8 to the position of FIG. 13, the rim 14 and the spindle portion 9 are slightly rotated in one direction (clockwise in FIG. 9). At this time, the connecting point (joining point) between the other end of the first rim 14 and one end of the second rim 14 is the other end of the first rim 14 from the rotation center of the spindle portion 9. The height of each hydraulic jack 25 is automatically adjusted so as to advance in an arc shape having a radius up to the coupling point between the portion and one end of the second rim 14. .
Then, as shown in FIG. 9, once the second spoke wire 26 can be stretched, the movement of the work carriage 7 is temporarily stopped, and the second spoke wire 26 is stretched between the spindle portion 9 and the rim 14. At this stage, the brake truss B is replaced with a brake truss Be whose length is approximately twice that of the brake truss B.

  When the extension of the second spoke wire 26 is completed, the work carriage 7 is gradually moved from the position shown in FIG. 9 to the position shown in FIG. 5, and the temporary support member 13, the rim 14 and the spindle 9 are slightly moved. Rotate in one direction (clockwise in FIG. 9). Also at this time, the connection point between the temporary support member 13 and the rim 14 proceeds in an arc shape having a radius from the rotation center of the spindle portion 9 to the connection point between the temporary support member 13 and the rim 14. The height of each hydraulic jack 25 is automatically adjusted. When the work carriage 7 reaches the position shown in FIG. 5 described above (that is, when the other end of the rim 14 is positioned between the columns 3 and 3), the movement of the work carriage 7 is stopped, A pipe-shaped horizontal member 14b (see FIG. 23) for connecting the rim 14 is engaged with a receiving portion provided at the tip of the brake truss Be (see FIG. 10), and the temporary support member 13, the rim 14 and the spindle are engaged. The portion 9 is prevented from rotating in the other direction (counterclockwise in FIG. 9). At this time, by operating the clamp mechanism 16 of the propulsion device 15 with the clamp mechanism, rotation of the temporary support member 13, the rim 14, and the spindle portion 9 in the other direction is prevented double. . Then, the work carriage 7 is retracted to the outside (right side in FIG. 9) from the workstation immediately below the spindle portion 9.

In the same manner as shown in FIGS. 7 to 9, the other end of the second rim 14 and the one end of the third rim 14 are joined, the third spoke wire 26 is stretched, and the third When the connection between the other end of the rim 14 and the one end of the fourth rim 14 and the extension of the fourth spoke wire 26 are completed, the second temporary support member 13 is attached as shown in FIG. It is attached to a predetermined position of the spindle unit 9. Since the procedure for attaching the temporary support member 13 to the spindle portion 9 has already been described with reference to FIG. 1, the description thereof is omitted here.
As shown in FIG. 11, when the second temporary support member 13 is attached to the spindle portion 9, the connection point between the first temporary support member 13 and the rim 14, the second temporary support member 13, and the rim. The tie wire 27 is stretched between the connection point with the tie wire 14.

Subsequently, in the same manner as shown in FIGS. 2 to 11, the other end of the fourth rim 14 and the one end of the fifth rim 14 are joined, and the fifth spoke wire 26 is extended. The connection between the other end of the fifth rim 14 and one end of the sixth rim 14, the extension of the sixth spoke wire 26, the other end of the sixth rim 14, and the seventh Coupling with one end of the rim 14, extending the seventh spoke wire 26, coupling the other end of the seventh rim 14 with one end of the eighth rim 14, and the eighth spoke wire 26 When the extension of is finished, the third temporary support member 13 is attached to a predetermined position of the spindle portion 9 as shown in FIG. Since the procedure for attaching the temporary support member 13 to the spindle portion 9 has already been described with reference to FIG. 1, the description thereof is omitted here.
As shown in FIG. 12, when the third temporary support member 13 is attached to the spindle portion 9, the connection point between the second temporary support member 13 and the rim 14, the third temporary support member 13, and the rim. The tie wire 27 is stretched between the connection point with the tie wire 14.

FIG. 13 is a front view of the stage where the construction of the fourteenth rim 14 of the rim 14 divided into twenty-eight has been completed. At this time, the load applied to the brake truss Be is maximized.
FIG. 14 is a front view of the stage where the construction of the sixteenth rim 14 of the twenty-eight divided rim 14 is completed, and FIG. 15 is the construction of the twenty-second rim 14 of the twenty-eight divided rim 14. FIG. 16 is a front view at the stage where the twenty-fourth rim 14 of the twenty-eight divided rim 14 is finished, and FIG. It is a front view of the stage which construction of the 8th rim | limb 14 was complete | finished.
Then, as shown in FIG. 17, the connection between the other end of the twenty-seventh rim 14 and one end of the twenty-eighth rim 14, and the other end of the twenty-eighth rim 14 The portion and the one end portion of the first rim 14 are combined on the work carriage 7. Thus, the other end of one rim 14 and one end of the other rim 14 disposed adjacent thereto are all performed on the work carriage 7.

When the mounting of all the rims 14 is completed, the seven temporary support members 13 are sequentially disassembled in a predetermined order by a method reverse to that used when assembling (attaching). FIG. 18 shows that one of the temporary support members 13 is removed from a predetermined position of the spindle portion 9 by removing a member located on the innermost side in the radial direction (that is, a member located closest to the spindle portion 9). It is the figure of the place lowered on the work cart 6.
FIG. 19 shows a state in which three of the temporary support members 13 are left, and a member located on the innermost side in the radial direction of the fourth temporary support member 13 is removed from a predetermined position of the spindle portion 9. It is the figure of the place lowered on the work cart 6.
FIG. 20 shows a state where the removal of all the temporary support members 13 and the removal of all the tie wires 27 are completed, and the construction work of the rim 14 is completed.
Thereafter, a cabin (or gondola) (not shown) is attached to a predetermined portion of the rim 14, and a driving device for driving is installed to complete the ferris wheel.

  According to the construction method of the ferris wheel according to the present embodiment, the entire work is provided on the rotary scaffold 10 provided on the spindle portion 9, the intermediate scaffold 11 and the lower scaffold 12 provided on the column 3, and the work carriage 7. This is performed only on the work scaffold 24. Therefore, it is possible to reliably ensure the safety of the worker, improve the work efficiency, and shorten the construction period. In addition, since it is not necessary to use a large crane, it is possible to construct a crane having any size regardless of the size of the ferris wheel.

  When the other end portion of one rim 14 and one end portion of another rim 14 arranged adjacent to each other are joined, the other rim 14 is placed on the hydraulic jack 25 of the work carriage 7, and each rim 14. Is not subjected to excessive force. Further, after the rims 14 are joined together, when the temporary support member 13, the rim 14 and the spindle portion 9 are slightly rotated in one direction, the work carriage 7 moves in the traveling direction in accordance with the rotation. The height of the hydraulic jack 25 is automatically adjusted so that an excessive force is not applied to each member.

  The intermediate scaffold 11 and the lower scaffold 12 provided in the column 3 are at a position suitable for assembling (connecting) or disassembling the three-part temporary support member 13, that is, a height at which the joint of the temporary support member 13 is located. The long temporary support member 13 can be assembled and disassembled easily and safely. Each of the divided temporary support members 13 is connected to one end of a winch wire 21 extending vertically downward from a winch 19 through a pulley 20 installed on the ground G and a pulley (not shown) attached to the rotary scaffold 10. Since it is attached to the part and assembled and disassembled, the work can be carried out efficiently and the construction period can be further shortened.

  Since the temporary support member 13 and the spoke wire 26 are all assembled while the temporary support member 13 and the spoke wire 26 are suspended vertically downward from the spindle portion 3, the assembly error is minimized. In addition, the work for correcting the assembly error can be omitted, and the construction period can be further shortened.

  By using the work carriage 7 in which the hydraulic jack 25 is installed on the work scaffold 24, the axial force when removing the temporary support member 13 can be easily released, so that the temporary support member 13 can be easily disassembled. The spoke wire 26 can be easily adjusted even after all the rims 14 are installed.

  By using the brake trusses B and Be, it is possible to reliably prevent the temporary support member 13, the rim 14, and the spindle portion 9 that are being installed from rotating in the other direction. Further, the other ends of the brake trusses B and Be (the end opposite to the tip portion on which the receiving portion is formed) are attached to the column foundation 1, so that the temporary support member 13 and the rim 14 that are being constructed are installed. , And the force that the spindle portion 9 tries to rotate in the other direction can be effectively transmitted to the column base 1.

The present invention is not limited to the above-described embodiment, and it is more preferable to use a brake truss Bs as shown in FIG. 25 instead of the brake trusses B and Be.
The brake truss Bs has a receiving portion (not shown) at its tip, and is assembled in a bowl shape. Like the brake truss B and Be described above, the brake truss Bs has a receiving portion provided at its tip. The temporary support member 13, the rim 14, and the spindle portion 9 are prevented from being rotated in the other direction (for example, counterclockwise in FIG. 5) by being engaged. The brake truss Bs is erected on separate foundations F1 and F2 that are embedded in the ground G and independent of the column foundation 1.

If such a brake truss Bs is used, the brake truss B is extended during the installation work (for example, when the second spoke wire 26 is extended between the spindle portion 9 and the rim 14 shown in FIG. 9). Therefore, it is not necessary to replace the brake truss with a brake truss Be that is approximately twice as long as the brake truss B, so that the work efficiency of the erection work can be improved and the construction period can be further shortened.
In addition, the brake truss Bs is firmly fixed on separate foundations F1 and F2 that are embedded in the ground G and independent of the column foundation 1, so that a more stable reaction force point is provided on the brake truss Bs. Therefore, the safety in erection work can be further improved.

  Furthermore, as shown in FIG. 26, it is more preferable that a plurality (two in this embodiment) of the propulsion devices 15 with a clamp mechanism are provided along the rotation direction (circumferential direction) of the rim 14.

As a result, the rails 14a of the rim 14 being installed are simultaneously supported (or clamped) by the clamp mechanisms 16 of the plural propulsion devices 15 with the clamp mechanism (a total of four in this embodiment). Therefore, even if the clamp mechanism 16 of some propulsion devices 15 with a clamp mechanism fails or is damaged, the rail 14a of the rim 14 is supported by the clamp mechanism 16 of another propulsion device 15 with a clamp mechanism that has not failed or is damaged. (Or can be clamped), the safety in the construction work can be further improved, and the rim 14 can be reliably prevented from rotating in the other direction (counterclockwise).
Further, the braking force can be applied to the rim 14 only by the clamp mechanism 16 of the propulsion device 15 with the clamp mechanism (the rim 14 can be prevented from rotating in the other direction (counterclockwise)). Therefore, the brake trusses B, Be, Bs can be used as secondary safety mechanisms.
