Description

[Technical Field]

[0001] The present disclosure relates to a blade storage device for storing blades of an axial flow rotary machine, and a blade storage method using the device. [Background technology]

[0002] Methods for storing blades of axial flow rotating machines include, for example, laying a sheet on the floor of the storage area and placing the blades on this sheet, as well as placing them on a stand as described in Patent Document 1 below.

[0003] The blade to be fabricated in the method of Patent Document 1 has a blade body and a shaft. The blade body has an airfoil-shaped cross section. The blade body extends in a blade height direction that has a component perpendicular to the cross section. The shaft is provided on one side of the blade body in the blade height direction. A shaft hole recessed in the blade height direction is formed in the shaft.

[0004] The stand used in the method described in Patent Document 1 has a mounting base and a support shaft. The outer diameter of the support shaft is large enough to be inserted into the shaft hole of the blade. The support shaft is fixed onto the mounting base so as to extend vertically upward from the mounting base.

[0005] When moving the wing, a string or the like is hung on the wing, and the wing is moved while suspended via the string or the like. At this time, the axis is on the lower side of the wing body, and the string or the like is hung on the edge of the wing body that is closest to the axis. When placing the wing on a stand, the support axis of the stand is inserted into the axis hole of the suspended wing. The load of the wing itself is basically borne by the mounting stand, and lateral loads on the wing are borne by the support axis. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2018-108629 Summary of the Invention [Problem to be solved by the invention]

[0007] The method described in Patent Document 1 has the advantage that the area required for storing the blades can be reduced because the blade height direction is vertical when the blades are stored.

[0008] In the method described in Patent Document 1, as mentioned above, the axis is positioned below the wing body, a string or the like is hung on the edge of the wing body that is closest to the axis, and the wing is moved while suspended via this string or the like, so the center of gravity of the wing is higher than the suspension position. For this reason, in the method described in Patent Document 1, the wing is unstable during movement, and great care must be taken to prevent the wing from tipping over and falling off the string or the like.

[0009] Furthermore, in the method described in Patent Document 1, when inserting the support shaft into the shaft hole of the blade, it is necessary to accurately align the position of the shaft hole with respect to the support shaft in the first horizontal direction and the second horizontal direction. Therefore, in the method described in Patent Document 1, attaching the blade to the frame is troublesome.

[0010] Therefore, an object of the present disclosure is to provide a wing storage device and a wing storage method that allow wings to be moved in a stable manner and are easily attached to a wing frame. [Means for solving the problem]

[0011] To achieve the above object, a wing storage device according to one aspect of the invention is provided. A blade storage device capable of storing a blade of an axial flow rotating machine, the blade having a blade body having an airfoil-shaped cross section and extending in a blade height direction with a directional component perpendicular to the cross section, and a rotating shaft provided at an end of the blade body in the blade height direction, includes: a hoisting device connectable to the end of the rotating shaft in the blade height direction; a connector capable of connecting the rotating shaft to the hoisting device; and a stand capable of suspending an object connected to the blade and the hoisting device via the connector. The hoisting device has a channel-shaped member and a wire attachment portion provided on the channel-shaped member to which a wire can be attached. The channel-shaped member has a pair of flange portions arranged at a distance from each other and a web portion connecting the pair of flange portions. One end of the pair of flange portions is connected to the web portion, and the other end forms an open end. The space surrounded by the pair of flange portions and the web portion forms a rod insertion space. An opening is formed between the open ends of the pair of flange portions. Of the first flange portion which is one of the pair of flange portions and the second flange portion which is the other flange portion, the second flange portion is configured to be connectable to the end face of the rotating shaft by the connector. The stand has at least one suspension rod which is inserted into the rod insertion space from the opening of the channel-shaped member and can suspend the object to be suspended, and a support base which supports the at least one suspension rod while the at least one suspension rod extends in a first horizontal direction.

[0012] In this embodiment, when the object to be hung is hung from the suspension rod of the stand, the wing height direction of the wing in the object to be hung is vertical, so the area required for storing the wing can be reduced.

[0013] In this embodiment, a sling is connected to the end of the wing in the wing height direction, and a wire is attached to this sling, so when a suspended object including the wing is suspended by this wire, the center of gravity of the wing is located below the suspension position of the wire. Therefore, in this embodiment, the wing can be moved in a stable state.

[0014] In this aspect, after the level of the opening in the channel member in the suspended object is aligned with the level of the suspension rod, the suspended object is moved horizontally, causing the suspension rod to enter the rod insertion space of the channel member through the opening in the channel member, and the suspended object is attached to the suspension rod of the cradle. Thus, in this aspect, the wing can be easily attached to the cradle.

[0015] To achieve the above object, one aspect of the invention of a wing storage method includes: A wing storage method using the wing storage device of the above-mentioned one aspect. This blade storage method includes a blade removal process for removing the blade from the casing of the axial flow rotating machine, a hoisting tool connection process for connecting the blade and the hoisting tool with the connector, a wire attachment process for attaching a wire to the wire attachment portion of the hoisting tool, an object moving process for moving the suspended object so that the suspended object is suspended from the at least one suspension rod while the suspended object is suspended by the wire, and a wire removal process for removing the wire from the suspended object after the object moving process. [Effects of the Invention]

[0016] According to one aspect of the present disclosure, the wing can be moved in a stable state and easily attached to the mount. [Brief explanation of the drawings]

[0018] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings.

[0019] "Embodiment of Axial Flow Rotating Machine" First, an embodiment of an axial flow rotary machine having blades that is the subject of the present disclosure will be described with reference to FIGS. 1 to 3. FIG.

[0020] As shown in FIG. 1, the axial flow rotary machine of this embodiment is a gas turbine.

[0021] The gas turbine of this embodiment includes an axial compressor 10 that compresses air A, a plurality of combustors 20 that burn fuel F in the air A compressed by the axial compressor 10 to generate combustion gas C, and a turbine 30 that is driven by the combustion gas C.

[0022] The axial flow compressor 10 includes a compressor rotor 11 that rotates about an axis Ar, a compressor casing 14 that covers the compressor rotor 11, multiple stator vane rows 15, and a guide vane row 16. The turbine 30 includes a turbine rotor 31 that rotates about the axis Ar, a turbine casing 34 that covers the turbine rotor 31, and multiple stator vane rows 35. In the following, the direction in which the axis Ar extends is referred to as the axial direction Da, the circumferential direction about the axis Ar is simply referred to as the circumferential direction Dc, and the direction perpendicular to the axis Ar is referred to as the radial direction Dr. One side of the axial direction Da is referred to as the axial upstream side Dau, and the opposite side is referred to as the axial downstream side Dad. The side of the radial direction Dr that approaches the axis Ar is referred to as the radially inner side Dri, and the opposite side is referred to as the radially outer side Dro.

[0023] The axial flow compressor 10 is disposed on the axial upstream side Dau with respect to the turbine 30 .

[0024] The compressor rotor 11 and the turbine rotor 31 are located on the same axis Ar and are connected to each other to form the gas turbine rotor 1. To this gas turbine rotor 1, for example, a rotor of a generator GEN is connected. The gas turbine further includes an intermediate casing 5. This intermediate casing 5 is arranged between the compressor casing 14 and the turbine casing 34 in the axial direction Da. The compressor casing 14, the intermediate casing 5, and the turbine casing 34 are connected to each other to form the gas turbine casing 4.

[0025] The compressor rotor 11 has a rotor shaft 12 extending in the axial direction Da around the axis Ar, and a plurality of rotor blade rows 13 attached to the rotor shaft 12. The plurality of rotor blade rows 13 are aligned in the axial direction Da. Each rotor blade row 13 is composed of a plurality of rotor blades aligned in the circumferential direction Dc. One of the plurality of stator blade rows 15 is arranged on the axial downstream side Dad of each of the plurality of rotor blade rows 13. Each stator blade row 15 is provided inside the compressor casing 14. Each stator blade row 15 is composed of a plurality of stator vanes aligned in the circumferential direction Dc. Of the plurality of stator blade rows 15, the blades constituting the first stator blade row 15 and the second stator blade row 15 from the axial upstream side Dau are both variable stator vanes 50. A guide vane row 16 is arranged in the compressor casing 14 at a position Dau upstream of the plurality of rotor blade rows 13. The guide vane row 16 is made up of a plurality of guide vanes 40 arranged in the circumferential direction Dc. The orientation of the plurality of guide vanes 40 is changed by a guide vane drive mechanism 17. The orientation of the plurality of variable stator vanes 50 is changed by a stator vane drive mechanism 18.

[0026] The turbine rotor 31 has a rotor shaft 32 extending in the axial direction Da centered on the axis Ar, and a plurality of rotor blade rows 33 attached to the rotor shaft 32. The plurality of rotor blade rows 33 are aligned in the axial direction Da. Each rotor blade row 33 is made up of a plurality of rotor blades aligned in the circumferential direction Dc. One of the plurality of stator blade rows 35 is arranged on the axial upstream side Dau of each of the plurality of rotor blade rows 33. Each stator blade row 35 is provided inside the turbine casing 34. Each stator blade row 35 is made up of a plurality of stator blades aligned in the circumferential direction Dc.

[0027] The air A compressed by the axial flow compressor 10 flows into the combustor 20. Furthermore, fuel F is supplied to the combustor 20 from the outside. The combustor 20 burns the fuel F in the compressed air A to generate high-temperature and high-pressure combustion gas C. This combustion gas C is sent to the turbine 30 and drives the turbine 30.

[0028] As shown in FIG. 2 , the guide vane 40 includes a blade body 41 and a casing-side rotating shaft 42. The blade body 41 has a blade-shaped cross section 41s and extends in a blade height direction Dh having a component perpendicular to the cross section 41s. Here, one side of the blade height direction Dh is referred to as a first blade height side Dh1, and the other side of the blade height direction Dh is referred to as a second blade height side Dh2. The casing-side rotating shaft 42 is provided on the first blade height side Dh1 of the blade body 41. This casing-side rotating shaft 42 extends in the blade height direction Dh. A threaded hole 42h is formed in the casing-side rotating shaft 42. This threaded hole 42h is recessed from an end surface 42p of the casing-side rotating shaft 42 on the first blade height side Dh1 toward the second blade height side Dh2. This casing-side rotating shaft 42 penetrates the compressor casing 14 and is connected to the guide vane drive mechanism 17. Therefore, when the guide vane 40 is attached to the compressor casing 14, the first blade height side Dh1, on which the casing side rotating shaft 42 is provided relative to the blade body 41, becomes the radially outer side Dro, and the second blade height side Dh2 becomes the radially inner side Dri.

[0029] As shown in FIG. 3 , the variable stator vane 50 includes a blade body 51, a casing-side rotating shaft 52, and a rotor-side rotating shaft 53. The blade body 51 has a blade-shaped cross section 51s and extends in a blade height direction Dh having a direction component perpendicular to the cross section 51s. The rotor-side rotating shaft 53 is provided on a second blade height side Dh2 of the blade body 51. The rotor-side rotating shaft 53 extends in the blade height direction Dh. A screw hole 53h is formed in the rotor-side rotating shaft 53. The screw hole 53h is recessed from an end face 53p of the rotor-side rotating shaft 53 on the second blade height side Dh2 toward the first blade height side Dh1. The casing-side rotating shaft 52 is provided on the first blade height side Dh1 of the blade body 51. The casing-side rotating shaft 52 extends in the blade height direction Dh. A screw hole 52h is formed in the casing-side rotating shaft 52. This screw hole 52h is recessed from an end surface 52p of the casing-side rotating shaft 52 on the first blade height side Dh1 to the second blade height side Dh2. This casing-side rotating shaft 52 penetrates the compressor casing 14 and is connected to the above-mentioned stator vane drive mechanism 18. Therefore, when the variable stator vane 50 is attached to the compressor casing 14, the first blade height side Dh1 on which the casing-side rotating shaft 52 is provided becomes the radially outer side Dro with respect to the blade body 51, and the second blade height side Dh2 becomes the radially inner side Dri.

[0030] The blades that are the subject of the present disclosure are the guide vanes 40 and the variable stator vanes 50 described above.

[0031] "Embodiments of storage device and storage method for guide vanes" Next, an embodiment of a storage device and a storage method for guide vanes will be described with reference to FIGS.

[0032] As shown in Fig. 4, the storage device S for guide vanes 40 includes a hoisting tool 60, a connector 78, and a stand 80. The hoisting tool 60 can be connected to the end of the casing-side rotation shaft 42 of the guide vane 40 in the blade height direction Dh. The connector 78 can connect the casing-side rotation shaft 42 and the hoisting tool 60. The stand 80 can suspend a hoisting object O, which has the guide vane 40 and the hoisting tool 60 connected by the connector 78.

[0033] As shown in FIGS. 5 and 6, the sling tool 60 includes a channel member 61, a wire attachment portion 70, and a bolt stopper 75.

[0034] The channel-shaped member 61 has a pair of flange portions 62 spaced apart from each other and a web portion 65 connecting the pair of flange portions 62 to each other. One end of each of the pair of flange portions 62 is connected to the web portion 65, and the other end forms open ends 63e, 64e. The first flange portion 63 of the pair of flange portions 62 has a flange main body 63b and a lip portion 63r. The flange main body 63b faces the second flange portion 64 of the pair of flange portions 62 at a distance. One end of the flange main body 63b is connected to the web portion 65. The lip portion 63r is provided at the end of the flange main body 63b opposite to the first end. The lip portion 63r extends from the flange main body 63b toward the second flange portion 64. The lip portion 63r forms the open end 63e of the first flange portion 63. The second flange portion 64 is configured to be connectable to the end face 42p of the casing-side rotating shaft 42 by a connector 78. Specifically, a bolt insertion hole 64h is formed in the second flange portion 64, penetrating in the direction in which the pair of flange portions 62 are aligned. The space surrounded by the pair of flange portions 62 and the web portion 65 forms a rod insertion space 66. In this channel-shaped member 61, an opening 67 to the rod insertion space 66 is formed between the opening end 63e of the first flange portion 63 and the opening end 64e of the second flange portion 64.

[0035] A wire attachment portion 70 is connected to the first flange portion 63 at a position opposite the rod insertion space 66. This wire attachment portion 70 is a shackle. The shackle has a U-shaped metal piece 72 and a swing shaft 73 that passes through both ends of the U-shaped metal piece 72. The swing shaft 73 is attached to the first flange portion 63. The U-shaped metal piece 72 can swing around the swing shaft 73. The area surrounded by the U-shaped metal piece 72 and the swing shaft 73 forms an insertion portion 71 through which the wire W can be inserted.

[0036] The wire attachment portion 70 may be in any form as long as it has an insertion portion through which the wire W can be inserted. For example, it may be an eyebolt or the like.

[0037] The connector 78 in this embodiment is a connecting bolt that can be inserted into the bolt insertion hole 64h and can be screwed into a screw hole 42h formed in the casing-side rotation shaft 42 of the guide vane 40.

[0038] The bolt removal stopper 75 serves to prevent the connection bolt 78 inserted through the bolt insertion hole 64h from slipping out of the bolt insertion hole 64h. As shown in FIG. 7 , the bolt removal stopper 75 has a notched ring 75r with a portion cut out and multiple claws 75t protruding inward from the inner periphery of the notched ring 75r. Due to its shape, the bolt removal stopper 75 is called an E-ring or E-shaped retaining ring. When the bolt head of the connection bolt 78 is positioned within the rod insertion space 66 of the channel-shaped member 61 and the threaded shank of the connection bolt 78 is inserted through the bolt insertion hole 64h of the second flange portion 64, the bolt removal stopper 75 is positioned on the opposite side of the rod insertion space 66 with respect to the second flange portion 64. The claws 75t of the bolt removal stopper 75 fit into the thread groove of the threaded shank.

[0039] As shown in FIGS. 4 and 8 to 11, the base 80 includes a plurality of suspension rods 81 and a support base 83 that supports the suspension rods 81. The support base 83 supports the suspension rods 81 so that each of the suspension rods 81 extends in a first horizontal direction H1. Here, one of the two sides in the first horizontal direction H1 is referred to as a first horizontal first side H11, and the other side is referred to as a first horizontal second side H12. The horizontal direction perpendicular to the first horizontal direction H1 is referred to as a second horizontal direction H2. One of the two sides in the second horizontal direction H2 is referred to as a second horizontal first side H21, and the other side is referred to as a second horizontal second side H22. In addition, in FIGS. 4, 8 to 11, and 14, some components are shown in one of the figures but not in the other figures. This is to make the characteristic configurations shown in each of FIGS. 4, 8 to 11, and 14 easier to see.

[0040] The support base 83 includes a base frame 84, a plurality of inclined columns 87, and rod support beams 88. The base frame 84 is rectangular. The rectangular base frame 84 includes a pair of long base members 85 that form the long sides of the rectangle and a pair of short base members 86 that form the short sides of the rectangle. The pair of long base members 85 extend in a second horizontal direction H2. The pair of short base members 86 extend in a first horizontal direction H1. An end of a first horizontal first side H11 of a first short base member 86a of the pair of short base members 86 is connected to an end of a second horizontal first side H21 of a first long base member 85a of the pair of long base members 85. An end of a first horizontal second side H12 of the first short base member 86a is connected to an end of the second horizontal first side H21 of a second long base member 85b of the pair of long base members 85. An end of the second horizontal second side H22 of the first long base material 85a is connected to an end of the first horizontal first side H11 of the pair of short base materials 86. An end of the first horizontal second side H12 of the first short base material 86a is connected to an end of the second horizontal second side H22 of the second long base material 85b.

[0041] Of the multiple inclined pillars 87, a first end of the first-A inclined pillar 87aa is connected to the end of the first horizontal first side H11 of the first short base material 86a. The first-A inclined pillar 87aa is disposed at an angle upward from the end of the first horizontal first side H11 of the first short base material 86a toward the first horizontal second side H12. Of the multiple inclined pillars 87, a first end of the first-B inclined pillar 87ab is connected to the end of the first horizontal second side H12 of the first short base material 86a. The first-B inclined pillar 87ab is disposed at an angle upward from the end of the first horizontal second side H12 of the first short base material 86a toward the first horizontal first side H11. The second end of the first-A inclined pillar 87aa is connected to the second end of the first-B inclined pillar 87ab. Therefore, the first short base material 86a, the first-A inclined pillar 87aa, and the first-B inclined pillar 87ab form an isosceles triangle structure.

[0042] Of the multiple inclined columns 87, a first end of the second-A inclined column 87ba is connected to the end of the first horizontal first side H11 of the second short base material 86b. This second-A inclined column 87ba is tilted upward from the end of the first horizontal first side H11 of the second short base material 86b toward the first horizontal second side H12. Of the multiple inclined columns 87, a first end of the second-B inclined column 87bb is connected to the end of the first horizontal second side H12 of the second short base material 86b. This second-B inclined column 87bb is tilted upward from the end of the first horizontal second side H12 of the second short base material 86b toward the first horizontal first side H11. A second end of the second-A inclined column 87ba is connected to the second end of the second-B inclined column 87bb. Therefore, the second short base material 86b, the second-A inclined column 87ba, and the second-B inclined column 87bb form an isosceles triangle structure.

[0043] The rod support beam 88 is supported by the two isosceles triangular structures and spans the vertices of the two isosceles triangular structures, so that the rod support beam 88 extends in the second horizontal direction H2.

[0044] Each of the multiple suspension rods 81 extends in a first horizontal direction H1 and is supported by a rod support beam 88 so as to be spaced apart from one another in a second horizontal direction H2. The multiple suspension rods 81 are connected to the rod support beam 88 at their intermediate portions in the first horizontal direction H1.

[0045] 10, the mutual intervals between the plurality of suspension rods 81 in the second horizontal direction H2 are such that the suspended objects O suspended from the respective suspension rods 81 cannot come into contact with each other. Specifically, this interval is such that even when the suspended object O is rotated around the central axis Ao of the casing-side rotation shaft 42 in the suspended object O, the suspended object O will not come into contact with other suspended objects O adjacent to the suspended object O in the second horizontal direction H2.

[0046] Each of the multiple suspension rods 81 has a first suspension portion 81a and a second suspension portion 81b capable of suspending a suspended object O. The first suspension portion 81a is part of a first horizontal first side H11 of the suspension rod 81, with the rod support beam 88 as the reference. Furthermore, the second suspension portion 81b is part of a first horizontal second side H12 of the suspension rod 81, with the rod support beam 88 as the reference. The distance between the first suspension portion 81a and the second suspension portion 81b in the first horizontal direction H1 is such that the suspended object O suspended by the first suspension portion 81a and the suspended object O suspended by the second suspension portion 81b cannot come into contact with each other. Specifically, this distance is such that even when the suspended object O is rotated around the central axis Ao of the casing-side rotation shaft 42 in the suspended object O, the suspended object O will not come into contact with other suspended objects O adjacent to the suspended object O in the first horizontal direction H1.

[0047] With the above configuration, mount 80 of the present embodiment can suspend a plurality of hanging objects O lined up in the second horizontal direction H2. Furthermore, mount 80 of the present embodiment can suspend a plurality of other hanging objects O lined up in the second horizontal direction H2 next to a plurality of hanging objects O lined up in the second horizontal direction H2. That is, mount 80 of the present embodiment can suspend a plurality of hanging objects O lined up in two rows.

[0048] The storage device S of this embodiment further includes a separation prevention mechanism 95, as shown in FIGS.

[0049] The separation prevention mechanism 95 includes a spacer 96 and a spacer support 97 that supports the spacer 96. The spacer support 97 includes a rod connecting plate 97a extending in the second horizontal direction H2 and a spacer pusher plate 97b connected to the end of the rod connecting plate 97a and extending vertically. Thus, the spacer support 97 is an L-shaped metal fitting. The rod connecting plate 97a is connected to the underside of the suspension rod 81. The rod connecting plate 97a extends from the connection position with the suspension rod 81 toward the second horizontal second side H22. The spacer pusher plate 97b extends upward from the end of the rod connecting plate 97a on the second horizontal second side H22. In the second horizontal direction H2, there is a gap between the spacer pusher plate 97b and the web outer surface 65p. The web outer surface 65p is the surface of the web portion 65 of the channel-shaped member 61 opposite the surface that defines the rod insertion space 66. The thickness of the spacer 96 is slightly thicker than this gap. Therefore, by inserting the spacer 96 into this gap, the channel-shaped member 61 can be moved in the second horizontal direction H2 relative to the suspension rod 81 located in the rod insertion space 66 of the channel-shaped member 61, and the web portion 65 of the channel-shaped member 61 can be pressed against the suspension rod 81. In other words, the separation prevention mechanism 95 is a mechanism that can press the web portion 65 of the channel-shaped member 61 against the suspension rod 81 located in the rod insertion space 66 of the channel-shaped member 61. When the web portion 65 of the channel-shaped member 61 is pressed against the suspension rod 81 in the rod insertion space 66, the suspension rod 81 cannot separate from the rod insertion space 66; in other words, the channel-shaped member 61 cannot separate from the suspension rod 81.

[0050] The mount 80 of this embodiment further includes a lateral vibration suppression mechanism 90, as shown in FIG.

[0051] The lateral vibration suppression mechanism 90 includes a pair of lateral vibration suppression rods 91 that can sandwich the plurality of suspended objects O constituting the first row in the first horizontal direction H1, a pair of lateral vibration suppression rods 91 that can sandwich the plurality of suspended objects O constituting the second row in the first horizontal direction H1, and rod support members 92 that detachably support the lateral vibration suppression rods 91. The rod support members 92 are fixed to both ends of the support base 83 in the second horizontal direction H2. The rod support members 92 are recessed downward and have grooves 93 into which the second horizontal direction H2 ends of each lateral vibration suppression rod 91 can be inserted. When the second horizontal direction H2 ends of each lateral vibration suppression rod 91 are inserted into the grooves 93 of the rod support members 92, each lateral vibration suppression rod 91 extends in the second horizontal direction H2 and faces, in the first horizontal direction H1, the casing-side rotation shafts 42 of the plurality of suspended objects O constituting the row. As a result, the plurality of suspended objects O constituting the first row are sandwiched between the pair of lateral vibration suppression rods 91 in the first horizontal direction H1, suppressing the swinging of the plurality of suspended objects O constituting the first row in the first horizontal direction H1. Furthermore, the plurality of suspended objects O constituting the second row are sandwiched between the pair of lateral vibration suppression rods 91 in the first horizontal direction H1, suppressing the swinging of the plurality of suspended objects O constituting the second row in the first horizontal direction H1.

[0052] Next, a method for storing the guide vanes 40 using the storage device S described above will be described with reference to the flowchart shown in FIG.

[0053] In this storage method, a wing detaching step S1, a sling connecting step S2, a wire attaching step S3, an object moving step S4, a wire detaching step S5, a separation prevention step S6, and a lateral vibration prevention step S7 are performed.

[0054] As shown in FIG. 16, when the guide vane 40 is attached to the compressor casing 14 , the casing-side rotating shaft 42 of the guide vane 40 is inserted into the rotating shaft insertion hole 19 of the compressor casing 14 .

[0055] In the blade removal process S1, strings ST made of nylon resin or the like are hung around the first blade height side Dh1 (radially inner side Dri) and the second blade height side Dh2 (radially outer side Dro) of the guide vane 40 attached to the compressor casing 14. Then, the strings ST are pulled to move the guide vane 40 to the radially inner side Dri, and the casing-side rotating shaft 42 of the guide vane 40 is pulled out of the rotating shaft insertion hole 19 of the compressor casing 14.

[0056] 17, the hoisting tool 60 is connected to the guide vane 40 removed from the compressor casing 14 with the connector 78 (hoisting tool connecting step S2). At this time, the second flange portion 64 of the grooved member 61 of the hoisting tool 60 and the end face 42p of the casing-side rotating shaft 42 of the guide vane 40 are opposed to each other, and the connecting bolt 78, which is the connector, is screwed into the threaded hole 42h of the casing-side rotating shaft 42 via the second flange portion 64.

[0057] Next, the wire W is attached to the wire attachment portion 70 of the suspender 60 connected to the guide wing 40 (wire attaching step S3). Note that the wire attaching step S3 may be performed before the suspender connecting step S2 in some cases.

[0058] 18, the end of the wire W is hung on a crane or the like, and with the suspended object O suspended by the wire W, the suspended object O is moved so that it is suspended from the suspension rod 81 (object moving step S4). In this object moving step S4, with the suspended object O suspended by the wire W, the casing-side rotation shaft 42 is on the upper side relative to the blade body 41 of the guide blade 40.

[0059] If, for example, the casing-side rotating shaft 42 of the guide vane 40 is positioned below the vane body 41, and a string ST or the like is hung around the edge of the vane body 41 at the edge where the casing-side rotating shaft 42 meets, and the guide vane 40 is suspended via this string ST, the center of gravity of the guide vane 40 will be located above the position where it is suspended by the string ST, etc. For this reason, if the guide vane 40 is suspended and moved in this manner, the guide vane 40 will be unstable during movement, and there is a risk that the guide vane 40 will tip over and fall off the string ST, etc.

[0060] In this embodiment, a suspending tool 60 is connected to the end of the guide vane 40 in the blade height direction Dh, and a wire W is attached to this suspending tool 60, so that when the suspended object O including the guide vane 40 is suspended by this wire W, the center of gravity G of the guide vane 40 is located below the suspension position by the wire W. Therefore, in this embodiment, the guide vane 40 can be moved in a stable state.

[0061] The suspended object O is moved, and when the suspended object O reaches the vicinity of the suspension rod 81, the level of the opening 67 in the channel member 61 in the suspended object O is adjusted to the level of the suspension rod 81. Then, the suspended object O is moved horizontally so that the suspension rod 81 enters the rod insertion space 66 of the channel member 61 through the opening 67 of the channel member 61. When the suspension rod 81 enters the rod insertion space 66 of the channel member 61 through this horizontal movement, the suspended object O is suspended by the suspension rod 81.

[0062] As described above, in this embodiment, the level of the opening 67 in the channel member 61 in the suspended object O is adjusted to the level of the suspension rod 81, and then the suspended object O is moved in the horizontal direction, whereby the suspended object O is attached to the pedestal 80. Therefore, in this embodiment, the guide vane 40 can be easily attached to the pedestal 80.

[0063] Next, the wire W attached to the wire attachment part 70 in the suspended object O is removed from the wire attachment part 70 (wire removing step S5).

[0064] 12, a spacer 96 is inserted between the web outer surface 65p of the channel member 61 and the spacer push plate 97b of the spacer support 97 (detachment prevention step S6). As a result, the web portion 65 of the channel member 61 is pressed against the suspension rod 81 located in the rod insertion space 66 of the channel member 61, and the suspension rod 81 cannot be detached from the rod insertion space 66. In other words, the channel member 61 cannot be detached from the suspension rod 81.

[0065] 14, a pair of lateral vibration suppression rods 91 are attached to grooves 93 of rod support members 92, and the casing-side rotating shaft 42 in the suspended object O is sandwiched between the pair of lateral vibration suppression rods 91 in the first horizontal direction H1 (lateral vibration suppression step S7). As a result, lateral vibration of the suspended object O in the first horizontal direction H1 is suppressed.

[0066] This completes the method for storing guide vanes 40. The suspended object O is suspended from the suspension rods 81, and is stored in a state in which separation from the suspension rods 81 is suppressed and lateral shaking is also suppressed. In this storage state, the blade height direction Dh of the guide vanes 40 in the suspended object O is vertical.

[0067] The wire detaching step S5, the separation suppression step S6, and the lateral vibration suppression step S7 may be performed in any order as long as they are performed after the object moving step S4.

[0068] In this embodiment, as described above, the blade height direction Dh of the guide vane 40 in the stored state is vertical, so that the area of ​​the storage location for the guide vane 40 can be reduced.

[0069] Furthermore, in this embodiment, as described above, the guide vanes 40 can be moved in a stable state and can be easily attached to the mount 80 .

[0070] Furthermore, in this embodiment, the plurality of guide vanes 40 can be stored in two rows. If the plurality of guide vanes 40 were stored in three or more rows, the plurality of guide vanes 40 in the middle row would be difficult to visually see due to the guide vanes 40 in the other rows. For this reason, in this case, it would be difficult to easily perform a visual inspection of the plurality of guide vanes 40 in the middle row. In this embodiment, the plurality of guide vanes 40 are stored in two rows, so that a visual inspection of all of the guide vanes 40 can be easily performed.

[0071] "Embodiments of storage device and storage method for variable stator vanes" Next, an embodiment of a storage device and a storage method for variable stator vanes will be described with reference to FIGS.

[0072] 19 , the storage device Sa for variable stator vanes 50 is basically the same as the storage device S for guide vanes 40. That is, like the storage device S for guide vanes 40, the storage device Sa for variable stator vanes 50 also includes a hoisting tool 60, a connector 78, a stand 80a, and a separation prevention mechanism 95. However, since the execution procedure for the storage method for variable stator vanes 50 is different from the execution procedure for the storage method for guide vanes 40, the arrangement of a portion of the stand 80a in the storage device Sa for variable stator vanes 50 is different from the arrangement of a portion of the stand 80 in the storage device S for guide vanes 40, as will be described later.

[0073] Next, a method for storing the variable stator vanes 50 will be described with reference to the flowchart shown in FIG.

[0074] The storage method for the variable stator vanes 50 also performs the blade removal step S1a, the lifting tool connecting step S2a, the wire attaching step S3a, the object moving step S4, the wire removing step S5, the separation prevention step S6, and the roll prevention step S7, similar to the storage method for the guide vanes 40. However, in the storage method for the variable stator vanes 50, the order of performing the lifting tool connecting step S2a and the wire attaching step S3a with respect to the blade removal step S1a is different from the order of performing the lifting tool connecting step S2 and the wire attaching step S3 with respect to the blade removal step S1 in the storage method for the guide vanes 40.

[0075] In the method for storing the variable stator vanes 50, a hoisting tool connecting step S2a and a wire attaching step S3a are performed in a state in which the variable stator vanes 50 are attached to the compressor casing 14.

[0076] 22, when the variable stator vane 50 is attached to the compressor casing 14, the casing-side rotating shaft 52 of the variable stator vane 50 is inserted into the rotating-shaft insertion hole 19a of the compressor casing 14. On the other hand, the rotor-side rotating shaft 53 of the variable stator vane 50 is not inserted into the shaft insertion hole or the like of the compressor casing 14. Therefore, with the casing-side rotating shaft 52 attached to the compressor casing 14, first, a hoisting tool connecting step S2a is performed on the rotor-side rotating shaft 53, and then a wire attaching step S3a is performed.

[0077] 21 and 22, in the hoisting tool connecting step S2a, the hoisting tool 60 is connected to the rotor-side rotating shaft 53 of the variable stator vane 50 in a state where it is attached to the compressor casing 14 using a connector 78. At this time, the second flange portion 64 of the grooved member 61 of the hoisting tool 60 and the end face 53p of the rotor-side rotating shaft 53 of the variable stator vane 50 are opposed to each other, and a connecting bolt 78, which is a connector, is screwed into the threaded hole 53h of the rotor-side rotating shaft 53 via the second flange portion 64. In the wire attaching step S3a, a wire W is attached to the wire attaching portion 70 of the hoisting tool 60 connected to the variable stator vane 50. Note that the wire attaching step S3a may be performed before the hoisting tool connecting step S2a, as the case may be.

[0078] In the blade removal process S1a, a string ST is hung on the first blade height side Dh1 (radial outer side Dro) of the variable stator vane 50 attached to the compressor casing 14. Then, the string ST and the previously attached wire W are pulled to move the variable stator vane 50 to the radial inner side Dri, and the casing-side rotating shaft 52 of the variable stator vane 50 is pulled out from the rotating shaft insertion hole 19a of the compressor casing 14.

[0079] In the blade removal step S1a in the method for storing the guide vane 40, as described above with reference to FIG. 16 , a string ST is hung around each of the first blade height side Dh1 (radially inner side Dri) and the second blade height side Dh2 (radially outer side Dro) of the guide vane 40 attached to the compressor casing 14. Then, these strings ST are pulled to move the guide vane 40 to the radially inner side Dri. However, in the blade removal step S1a in the method for storing the variable stator vane 50, the wire W attached to the wire attachment portion 70 serves as the string ST that is hung around the second blade height side Dh2 (radially inner side Dri) of the guide vane 40 in the blade removal step S1 in the method for storing the guide vane 40. Therefore, in the blade removal step S1a in the method for storing the variable stator vane 50, the effort required for hanging the string ST can be reduced compared to the blade removal step S1 in the method for storing the guide vane 40.

[0080] In the subsequent processes in the storage method for the variable stator vane 50, the object moving process S4, the wire removing process S5, the detachment prevention process S6, and the lateral sway prevention process S7 are executed, similar to the processes after the blade removing process S1, the lifting device connecting process S2, and the wire attaching process S3 in the storage method for the guide vane 40.

[0081] However, in the object moving step S4 in the storage method of the variable stator vane 50, because the hoisting tool 60 is connected to the rotor-side rotating shaft 53 in the hoisting tool connecting step S2a, when the suspended object Oa is suspended by the wire W, the rotor-side rotating shaft 53 is positioned above the blade body 51 of the variable stator vane 50. Even if the rotor-side rotating shaft 53 is positioned above the blade body 51 of the variable stator vane 50 in this way, as in the storage method of the guide vane 40, the hoisting tool 60 is connected to the end of the variable stator vane 50 in the blade height direction Dh, and the wire W is attached to this hoisting tool 60. Therefore, in the storage method of the variable stator vane 50, as in the storage method of the guide vane 40, when the suspended object Oa including the variable stator vane 50 is suspended by the wire W, the center of gravity of the variable stator vane 50 is positioned below the suspension position by the wire W. Therefore, even in the storage method of the variable stator vane 50, the variable stator vane 50 can be moved in a stable state. Furthermore, in this method of storing the variable stator vanes 50, similar to the method of storing the guide vanes 40, the variable stator vanes 50 can be easily attached to the mount 80a.

[0082] Furthermore, when the object moving step S4 in the storage method for the variable stator vanes 50 is completed and the hanging object Oa is hung from the suspension rods 81, the blade height direction Dh of the variable stator vanes 50 in the hanging object Oa becomes vertical. Therefore, in the storage method for the variable stator vanes 50, as in the storage method for the guide vanes 40, the area of ​​the storage location for the variable stator vanes 50 can be reduced. However, in this embodiment, when the hanging object Oa is hung from the suspension rods 81, the rotor-side rotating shaft 53 is on the upper side and the casing-side rotating shaft 52 is on the lower side with respect to the blade body 51 of the variable stator vane 50.

[0083] 19 , in the roll suppression mechanism 90a of the present embodiment, the casing-side rotating shaft 52 is sandwiched between a pair of roll suppression rods 91, similar to the roll suppression mechanism 90 of the guide vane 40. However, in the present embodiment, as described above, when the suspended object Oa is suspended from the suspension rods 81, the casing-side rotating shaft 52 is located below the blade body 51 of the variable stator vane 50. For this reason, in the present embodiment, the roll suppression mechanism 90a including the roll suppression rods 91 is attached to the support base 83 at a lower position than the roll suppression mechanism 90 of the guide vane 40. This is the point where the mount 80a of the variable stator vane 50 differs from the mount 80 of the guide vane 40.

[0084] "Variations" The configuration of the separation prevention mechanism is not limited to the configuration of the separation prevention mechanism 95 described above with reference to FIGS. 12 and 13. For example, as shown in FIGS. 23 and 24, the separation prevention mechanism 95a may be configured with a pin 98 and a pin hole 99 formed in the interdigital member 61. The pin hole 99 includes a first pin hole 99a formed in the first flange portion 63 and a second pin hole 99b formed in the second flange portion 64. The first pin hole 99a and the second pin hole 99b both extend in the flange arranging direction, which is the direction in which the first flange portion 63 and the second flange portion 64 are arranged. Furthermore, the position of the first pin hole 99a in the direction perpendicular to the flange arranging direction coincides with the position of the second pin hole 99b in the direction perpendicular to the flange arranging direction. Therefore, one pin 98 can be inserted through both the first pin hole 99a and the second pin hole 99b.

[0085] The distance between the web portion 65 and the edges of the first pin hole 99a and the second pin hole 99b on the web portion 65 side is slightly narrower than the distance between the web portion 65 and the edge of the lip portion 63r on the web portion 65 side. Therefore, when a pin 98 is inserted into the first pin hole 99a and the second pin hole 99b, the pin 98 can press the suspension rod 81 in the rod insertion space 66 toward the web portion 65. In other words, like the separation prevention mechanism 95 in the above-described embodiment, this separation prevention mechanism 95a is a mechanism that can press the web portion 65 of the channel-shaped member 61 against the suspension rod 81 located in the rod insertion space 66 of the channel-shaped member 61.

[0086] The separation prevention mechanism may be a mechanism that can press the first flange portion 63 of the channel-shaped member 61 against the suspension rod 81 located in the rod insertion space 66 of the channel-shaped member 61. In this case, the separation prevention mechanism can be configured with a spacer that can be inserted between the second flange portion 64 and the suspension rod 81 located in the rod insertion space 66 of the channel-shaped member 61.

[0087] In the above description, the guide vanes 40 and variable stator vanes 50 in the axial compressor 10 of a gas turbine are taken as an example of a blade. However, the blades of the present disclosure are not limited to the guide vanes 40 and variable stator vanes 50 in the axial compressor 10 of a gas turbine, and may be any blade as long as it has a blade body and a rotating shaft provided at the end of the blade body.

[0088] Furthermore, the present disclosure is not limited to the embodiment and modifications described above, and various additions, modifications, substitutions, partial deletions, etc. are possible within the scope of the conceptual idea and spirit of the present invention as derived from the content defined in the claims and their equivalents.

[0092] In this embodiment, a suspending tool 60 is connected to the end of the wings 40, 50 in the wing height direction Dh, and a wire W is attached to this suspending tool 60, so that when the suspended object O, Oa including the wings 40, 50 is suspended by this wire W, the center of gravity G of the wings 40, 50 is located below the suspension position by the wire W. Therefore, in this embodiment, the wings 40, 50 can be moved in a stable state.

[0093] In this embodiment, the level of opening 67 of channel member 61 in suspended object O, Oa is adjusted to the level of suspension rod 81, and then suspended object O, Oa is moved horizontally, whereby suspended object O, Oa is attached to suspension rod 81 of mount 80, 80a.
