Description

[Technical field]

[0001] The present invention relates to a structure cutting system, a structure cutting method, and a cutting machine system. [Background technology]

[0002] In recent years, wind power generation devices that have a small environmental impact have been attracting attention. Wind power generation devices that have exceeded their useful life are disassembled, and the blades and other parts are discarded. Since the blades and other parts are huge structures, they cannot be easily transported, which incurs a large cost. For this reason, it is desirable to transport huge structures such as the blades of wind power generation devices after dividing them into smaller pieces.

[0003] For example, Patent Document 1 discloses a work vehicle equipped with a long-length processing device. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 5-319164 Summary of the Invention [Problem to be solved by the invention]

[0005] However, there has been no machine suitable for cutting such a large structure. Although it is possible to cut it with hand tools, it requires a tremendous amount of labor. In other words, a cutting system suitable for cutting such a large structure is desired. [Means for solving the problem]

[0006] A structure cutting system according to one embodiment of the present invention includes a cutting machine system mounted on a first moving body moving on land or sea and cutting a structure to be cut, and a material feeding machine system mounted on a second moving body moving on land or sea independently of the first moving body and feeding the structure to the cutting machine system. The structure is placed so as to straddle between the cutting machine system and the material feeding machine system. The material feeding machine system feeds the structure to the cutting machine system as the second moving body approaches the first moving body. The cutting machine system cuts the structure fed from the material feeding machine system, thereby cutting the structure into a plurality of cut materials.

[0007] According to the structure cutting system of one aspect of the present invention, since the cutting machine system and the material feed machine system are mounted on the first and second moving bodies, the cutting machine system and the material feed machine system can be moved to any location. Therefore, the structure cutting system can be constructed at a location where a huge structure exists, and there is no need to transport the huge structure at great expense in order to cut it. In addition, since the cutting machine system and the material feed machine system can be separated by a required distance by the first and second moving bodies, the cutting machine system and the material feed machine system can appropriately support the huge structure. In addition, since the material feed machine system can send out the structure to the cutting machine system by moving the second moving body, the cutting machine system can cut the huge structure. This allows the huge structure to be divided into smaller pieces on the spot. Effect of the Invention

[0008] According to one aspect of the present invention, a cutting system suitable for cutting large structures can be provided. [Brief description of the drawings]

[0010] Hereinafter, a structure cutting system, a structure cutting method, and a cutting machine system according to the present embodiment will be described with reference to the drawings.

[0011] Fig. 1 is a side view showing a schematic configuration of a structure cutting system according to this embodiment. Fig. 2 is a top view showing a schematic configuration of a structure cutting system according to this embodiment. In the following description, three-dimensional directions are defined as left-right, front-rear, and up-down directions. The left-right and front-rear directions correspond to two directions that are orthogonal to the horizontal direction, and the up-down direction corresponds to the vertical direction. However, these directions are merely used for convenience in explaining the configuration of the structure cutting system.

[0012] The structure cutting system 1 according to this embodiment includes a cutting machine system 2 mounted on a first moving body moving on land or sea and cutting the structure to be cut, and a material feeding machine system 5 mounted on a second moving body moving on land or sea independently of the first moving body and feeding the structure to the cutting machine system 2. The structure is placed so as to straddle between the cutting machine system 2 and the material feeding machine system 5. The material feeding machine system 5 feeds the structure to the cutting machine system 2 as the second moving body approaches the first moving body. The cutting machine system 2 cuts the structure fed from the material feeding machine system 5, thereby dividing the structure into a plurality of cut materials.

[0013] The configuration of the structure cutting system 1 will be described in detail below. In the following description, the blade 8 of a wind power generation device will be exemplified as the structure to be cut. This blade 8 has a longitudinal shape that extends in one direction while being twisted. As shown in Figs. 1 and 2, the structure cutting system 1 includes a cutting machine system 2 that cuts the blade 8, and a material feeding machine system 5 that feeds the blade 8 to the cutting machine system 2. In the example shown in Figs. 1 and 2, the front-rear direction corresponds to the longitudinal direction of the blade 8 and the material feeding direction in which the blade 8 is fed, and the left-right direction corresponds to the width direction that intersects with the material feeding direction (orthogonal in this embodiment).

[0014] The cutting machine system 2 includes a cutting machine base 30 and a cutting machine unit 35. The cutting machine system 2 is mounted on a trailer 20 (hereinafter referred to as the "cutting side trailer 20"), which is an example of a first moving body that moves on the ground. The cutting side trailer 20 includes a loading platform 21 on which an object to be transported, such as a container, is loaded, and a towing vehicle 22 that tows the loading platform 21. First fastening devices 23 that detachably fasten the object to be transported are provided at the four corners of the loading platform 21. The first fastening devices 23 are, for example, twist locks.

[0015] The cutter base 30 is a flat base material on which the cutter unit 35 is mounted. The cutter unit 35 is fixed to the cutter base 30 by fastening means such as bolts.

[0016] The cutting machine base 30 has a shape and size similar to, but not limited to, the loading platform 21 of the cutting side trailer 20. A first fastening portion 31 to which the first fastening device 23 is fixed is provided on the underside of the cutting machine base 30 in correspondence with the first fastening device 23 on the loading platform 21 side. The first fastening portion 31 is formed of an elongated hole or the like suitable for inserting the first fastening device 23. The cutting machine base 30 is detachably fixed to the cutting side trailer 20 via the first fastening device 23 of the loading platform 21.

[0017] The cutting unit 35 includes various elements for cutting the blade 8. Specifically, the cutting unit 35 includes a first support mechanism 36, a cutting machine 37, a second support mechanism 38, an alignment member 39, a first width-shifting mechanism 40, a second width-shifting mechanism 41, and an operation panel 42.

[0018] The first support mechanism 36 is provided on the front side of the cutting machine 37, i.e., on the loading side where the blade 8 is loaded into the cutting machine 37. The first support mechanism 36 supports the blade 8 sent from the material feeder system 5 to the cutting machine 37. The first support mechanism 36 supports the blade 8 so that a conveying height (pass line) for conveying the blade 8 is a predetermined reference height Ha. For example, the first support mechanism 36 is composed of a first rotating roller 360 that rotates about a rotation axis extending in the left-right direction, and support legs 361 and 362 that rotatably support the first rotating roller 360.

[0019] 3 and 4 are explanatory diagrams showing a schematic configuration of the cutting machine 37. The cutting machine 37 cuts the blade 8 supported by the first support mechanism 36. In the example shown in Figs. 3 and 4, the cutting machine 37 is composed of a horizontal band saw. The cutting machine 37 is mainly composed of a saw blade housing 370 and a hinge mechanism 375.

[0020] The saw blade housing 370 includes a drive wheel 371, a driven wheel 372, and a band saw blade 373 suspended between the drive wheel 371 and the driven wheel 372. The drive wheel 371 and the driven wheel 372 are rotatably attached to the saw blade housing 370. Power is transmitted to the drive wheel 371 from a drive mechanism including a motor, gears, etc., and the drive wheel 371 is driven to rotate by receiving the power. The band saw blade 373 runs due to the rotational drive of the drive wheel 371.

[0021] The hinge mechanism 375 includes a hinge shaft 376 that is provided parallel to the rotation shaft of the drive wheel 371. The saw blade housing 370 is fixed to the cutting machine base 30 via the hinge mechanism 375 and is configured to be rotatable around the hinge shaft 376. The saw blade housing 370 can be rotated between an upper limit position (see FIG. 3) where the running line of the band saw blade 373 is substantially vertical and a lower limit position (see FIG. 4) where the running line of the band saw blade 373 is substantially horizontal. When the saw blade housing 370 is in the lower limit position, the running line of the band saw blade 373 is set to be lower than the height of the blade 8 supported by the first support mechanism 36, i.e., the reference height Ha.

[0022] 1 and 2 again, the second support mechanism 38 is provided at a position facing the first support mechanism 36 across the cutting machine 37. That is, the second support mechanism 38 is provided on the rear side of the cutting machine 37, i.e., on the discharge side where the blade 8 (material to be cut) cut by the cutting machine 37 is discharged. The second support mechanism 38 supports the blade 8 cut by the cutting machine 37.

[0023] For example, the second support mechanism 38 includes a pair of supports 380, 381 that can be raised and lowered in the vertical direction. The pair of supports 380, 381 are arranged at a certain distance apart in the front-rear direction. The blade 8 cut by the cutting machine 37 is supported at two points by the pair of supports 380, 381. Each of the supports 380, 381 is provided with a drive mechanism such as a hydraulic cylinder, and receives power from the drive mechanism to independently rise and fall in the vertical direction. This allows each of the supports 380, 381 to support the blade 8 at the same height as the reference height Ha at which the first support mechanism 36 supports the blade 8, or at a height different from the reference height Hb.

[0024] The alignment member 39 aligns the position of the blade 8 relative to the cutter 37 by contacting the end surface 8a of the blade 8 extending along the front-rear direction. For example, the alignment member 39 is composed of a second rotating roller 390 that rotates about a rotation axis extending in the up-down direction, and a base portion (not shown) that rotatably supports the second rotating roller 390. In the example shown in FIG. 1, the alignment member 39 is provided between the first support mechanism 36 and the cutter 37.

[0025] The first width-shifting mechanism 40 is provided at a position facing the alignment member 39 in the left-right direction. The first width-shifting mechanism 40 includes a first movable body 400 configured to be movable in the left-right direction, and a drive mechanism (not shown) such as a hydraulic cylinder that moves the first movable body 400 in the left-right direction. The first width-shifting mechanism 40 fixes the blade 8 between the alignment member 39 by moving the first movable body 400 in the right direction. The first width-shifting mechanism 40 releases the fixation of the blade 8 by moving the first movable body 400 in the left direction. The first movable body 400 can move in the left direction up to a predetermined fully open position.

[0026] The second width-shifting mechanism 41 is mounted on the front support 380 of the second support mechanism 38. The second width-shifting mechanism 41 includes a pair of second movable bodies 410, 411 provided at positions facing each other in the left-right direction, and a drive mechanism (not shown) such as a hydraulic cylinder. The pair of second movable bodies 410, 411 are configured to be movable in the left-right direction, and each of them moves along the left-right direction upon receiving power from the drive mechanism. The second width-shifting mechanism 41 fixes the blade 8 between the pair of second movable bodies 410, 411 by moving the pair of second movable bodies 410, 411 toward each other along the left-right direction. The second width-shifting mechanism 41 also releases the fixation of the blade 8 by moving the pair of second movable bodies 410, 411 away from each other along the left-right direction. The pair of second movable bodies 410, 411 can each move in the left-right direction to a predetermined fully open position.

[0027] The operation panel 42 is a device for operating the cutting machine 37, the second support mechanism 38, the first shifting mechanism 40, and the second shifting mechanism 41. The operation panel 42 is operated by an operator who uses the structure cutting system 1, for example.

[0028] The material conveying machine system 5 comprises a material conveying machine base 60 and a material conveying machine unit 65. The material conveying machine system 5 is mounted on a trailer 50 (hereinafter referred to as the "material conveying trailer 50"), which is an example of a second moving body that moves on the ground. The material conveying trailer 50 comprises a loading platform 51 on which transported goods such as containers are loaded, and a towing vehicle 52 which tows the loading platform 51. Second fastening devices 53 which detachably fasten the transported goods are provided at the four corners of the loading platform 51. The second fastening devices 53 are, for example, twist locks.

[0029] The material feeder base 60 is a flat base material on which a material feeder unit 65 is mounted. The material feeder unit 65 is fixed to the cutting machine base 30 by fastening means such as bolts.

[0030] The material feed machine base 60 has a shape and size equivalent to, but not limited to, the loading platform 51 of the material feed trailer 50. A second fixed portion 61 to which the second fastening device 53 is fixed is provided on the underside of the material feed machine base 60 in correspondence with the second fastening device 53 on the loading platform 51 side. The second fixed portion 61 is formed of an elongated hole or the like suitable for inserting the second fastening device 53. The material feed machine base 60 is detachably fixed to the material feed trailer 50 via the second fastening device 53 of the loading platform 51.

[0031] The material feed unit 65 includes various elements for feeding the blade 8 to the cutting machine system 2. Specifically, the material feed unit 65 includes a third support mechanism 66, a butting section 67, a third width adjustment mechanism 68, and an operation panel 69.

[0032] The third support mechanism 66 supports the blade 8 to be sent out to the cutting machine system 2. The third support mechanism 66 supports the blade 8 so that a conveying height (pass line) for conveying the blade 8 is a predetermined reference height Ha.

[0033] The abutment portion 67 is a vertical wall-shaped member that stands in the vertical direction. When the cutting machine system 2 moves rearward, the tip 8b of the blade 8 in the front-rear direction abuts against the abutment portion 67, thereby pushing the blade 8 toward the cutting machine system 2.

[0034] The third width-shifting mechanism 68 is provided between the abutting portion 67 and the third support mechanism 66. The third width-shifting mechanism 68 includes a pair of third movable bodies 680, 681 provided at positions facing each other in the left-right direction, and a drive mechanism (not shown) such as a hydraulic cylinder. The pair of third movable bodies 680, 681 are configured to be movable in the left-right direction, and each of them moves along the left-right direction upon receiving power from the drive mechanism. The third width-shifting mechanism 68 fixes the blade 8 between the pair of third movable bodies 680, 681 by moving the pair of third movable bodies 680, 681 toward each other along the left-right direction. The third width-shifting mechanism 68 also releases the fixation of the blade 8 by moving the pair of third movable bodies 680, 681 away from each other along the left-right direction. The pair of third movable bodies 680, 681 can each move in the left-right direction to a predetermined fully open position.

[0035] The operation panel 69 is a device for operating the operation of the third shifting mechanism 68. The operation panel 42 is operated by an operator who uses the structure cutting system 1, for example.

[0036] Figures 5 to 10 are diagrams for explaining the structure cutting method according to this embodiment. Below, the structure cutting method according to this embodiment, that is, the cutting method of the blade 8 by the structure cutting system 1, will be explained. Note that, for the sake of convenience, the operation panels 42 and 69 are omitted in Figures 5 to 10.

[0037] First, as shown in Fig. 5, the material-feeding trailer 50 is positioned relative to the cutting-side trailer 20. With this positioning, the trailers 20, 50 are positioned so that the straight-line direction (forward and backward directions) of the cutting-side trailer 20 intersects with the straight-line direction of the material-feeding trailer 50, and the cutting-side trailer 20 is positioned on an extension of the backward direction of the material-feeding trailer 50. In the example shown in Fig. 5, the cutting-side trailer 20 is positioned facing right in the left-right direction, and the material-feeding trailer 50 is positioned facing forward in the front-rear direction. The two trailers 20, 50 are then lined up on a straight line parallel to the front-rear direction so that their straight-line directions are perpendicular to each other.

[0038] When the two trailers 20, 50 are positioned, the operator operates the operation panels 42, 69 to move the first movable body 400 of the first shifting mechanism 40, the pair of second movable bodies 410, 411 of the second shifting mechanism 41, and the pair of third movable bodies 680, 681 of the third shifting mechanism 68 to the fully open position. The operator operates the operation panel 42 to lower the pair of supports 380, 381 of the second support mechanism 38 to the lowest position.

[0039] Next, as shown in FIG. 6, the operator operates the operation panel 42 to move the saw blade housing 370 to the upper limit position.

[0040] The blade 8 to be cut is brought in from above using an external crane or the like, and placed so as to straddle between the cutting machine system 2 and the material feed machine system 5. The blade 8 is supported by the first support mechanism 36 of the cutting machine system 2 and the third support mechanism 66 of the material feed machine system 5, respectively.

[0041] At this time, the blade 8 is placed with the longitudinal direction of the blade 8 coinciding with the front-rear direction. The tip 8b of the blade 8 on the side of the material feeding machine system 5 is in abutment with the abutting portion 67. In addition, the end face 8a of the blade 8 along the front-rear direction is in contact with the alignment member 39.

[0042] When the blade 8 is placed, the operator operates the operation panel 69 to perform a width-shifting operation by the third width-shifting mechanism 68. In this width-shifting operation, the pair of third movable bodies 680, 681 move toward each other in the left-right direction. The blade 8 is fixed between the pair of third movable bodies 680, 681.

[0043] Next, as shown in FIG. 7, the material feeding trailer 50 is moved backward, so that the material feeding system 5 sends out the blade 8 to the cutting machine system 2 in the longitudinal direction of the blade 8. The material feeding trailer 50 is moved backward by a predetermined distance so that the cutting position Pb of the blade 8 reaches the cutting machine 37 of the material feeding system 5. The cutting position Pb of the blade 8 is determined in consideration of the center of gravity of the material to be cut, which is the blade 8, and the length of the material to be cut. Specifically, the cutting position Pb of the blade 8 is determined so that the center of gravity of the material to be cut is located between the pair of supports 380, 381 of the second support mechanism 38, and so that the length of the material to be cut is a length that can be transported by land.

[0044] When the material feeding machine system 5 feeds out the blade 8, the material feeding trailer 50 is moved backward while adjusting the backward movement direction of the material feeding trailer 50 so that the end face 8a of the blade 8 is kept in contact with the alignment member 39. By keeping the end face 8a of the blade 8 in contact with the alignment member 39, the blade 8 can be fed out so as to fit within the cutting area of ​​the cutter 37. Here, the cutting area of ​​the cutter 37 is the area where the band saw blade 373 cuts the blade 8, and corresponds to the area between the drive wheel 371 and the driven wheel 372 of the band saw blade 373.

[0045] 8, the operator operates the operation panel 42 to perform a width-shifting operation by the width-shifting mechanisms on the cutting machine system 2 side, i.e., the first width-shifting mechanism 40 and the second width-shifting mechanism 41. In this width-shifting operation, the first movable body 400 moves rightward, and the pair of second movable bodies 410, 411 move toward each other in the left-right direction. By the width-shifting operation, the blade 8 is fixed between the alignment member 39 and the first movable body 400, and is also fixed between the pair of third movable bodies 680, 681.

[0046] The operator operates the operation panel 42 to raise the pair of supports 380 and 381 of the second support mechanism 38 until they abut against the blade 8.

[0047] The operator also operates the operation panel 42 to rotate the saw blade housing 370 to the lower limit position while running the band saw blade 373 of the cutting machine 37, and then returns it to the upper limit position. As a result, the blade 8 is cut (divided) by the cutting machine 37, as shown in Fig. 9. The cutting material, which is the blade 8 cut by the cutting machine 37, is supported by a pair of supports 380, 381 of the second support mechanism 38.

[0048] As shown in FIG. 10, the operator operates the operation panels 42, 69 to move the first width-shifting mechanism 40 and the second width-shifting mechanism 41 to the fully open position. The material to be cut is removed from the second support mechanism 38 by a crane or the like. The above-mentioned operation is then repeated for a new cutting position Pb1 on the remaining blade 8, so that the blade 8 is cut into a plurality of materials to be cut. Since there are a plurality of blades 8 for the wind turbine generator, it is possible to store the operation of the operator and automatically reuse them. Also, if the shape of the blade is set in advance, it is possible to automate the process, including the operation of the material-delivery trailer 50.

[0049] As described above, the structure cutting system 1 of this embodiment includes the cutting machine system 2 mounted on the cutting side trailer 20, and the material feeding machine system 5 mounted on the material feeding trailer 50. The blade 8 is placed so as to straddle between the cutting machine system 2 and the material feeding machine system 5. The material feeding machine system 5 sends out the blade 8 to the cutting machine system 2 as the material feeding trailer 50 approaches the cutting side trailer 20. The cutting machine system 2 cuts the blade 8 sent out from the material feeding machine system 5, thereby dividing the blade 8 into a plurality of cut materials.

[0050] According to this configuration, since the cutting machine system 2 and the material feed machine system 5 are mounted on the cutting side trailer 20 and the material feed side trailer 50, the cutting machine system 2 and the material feed machine system 5 can be moved to any location. Since the structure cutting system 1 can be constructed at a location where the blade 8, which is a huge structure, is present, there is no need to transport the huge blade 8 at great expense. In addition, since the cutting machine system 2 and the material feed machine system 5 can be separated by a required distance by the cutting side trailer 20 and the material feed side trailer 50, both sides of the blade 8 can be supported according to the length of the huge blade 8. In addition, since the material feed side trailer 50 moves, the material feed machine system 5 can send out the blade 8 to the cutting machine system 2, so that the cutting machine system 2 can cut the huge structure. As a result, the huge blade 8 can be cut into small pieces on the spot.

[0051] In this way, according to the structure cutting system 1 according to this embodiment, a system suitable for cutting a huge blade 8 can be provided.

[0052] In this embodiment, the cutting machine system 2 includes a first support mechanism 36 that supports the blade 8 fed out along the longitudinal direction, a cutting machine 37 that cuts the blade 8 supported by the first support mechanism 36, a second support mechanism 38 that is arranged to be freely raised and lowered in the vertical direction at a position facing the first support mechanism 36 across the cutting machine 37 and supports the cutting material (the blade 8 after cutting) cut by the cutting machine 37, and an alignment member 39 that aligns the position of the blade 8 relative to the cutting machine 37 by contacting an end face 8a of the blade 8.

[0053] According to this configuration, the first support mechanism 36 and the second support mechanism 38 are disposed across the cutting machine 37. Therefore, the first support mechanism 36 can support the blade 8 on the carry-in side of the cutting machine 37, and the second support mechanism 38 can support the blade 8 on the carry-out side of the cutting machine 37. This allows the cutting machine 37 to properly cut the blade 8.

[0054] In addition, in a stationary cutting machine such as a normal horizontal band saw, the pass line (reference height Ha), which is the conveying height at which the workpiece is conveyed, is at a constant height from the carry-in side to the carry-out side. However, in the material feeder system 5 according to this embodiment, the cutting machine system 2 and the material feeder system 5 are independent and placed at any location, so the cutting machine system 2 and the material feeder system 5 are not necessarily placed in the same height environment due to the inclination or undulation of the ground. In addition, the blade 8 to be cut has a shape that is twisted along the longitudinal direction, so the blade 8 does not have a shape that follows the pass line.

[0055] 11 is a diagram showing the relationship between the cutting machine system and the material feed machine system. According to the cutting machine system 2 of this embodiment, the second support mechanism 38 provided on the discharge side of the cutting machine 37 is configured to be able to move up and down in the vertical direction. Even if the path line of the cutting machine system 2 and the path line of the material feed machine system 5 are different, or if a blade 8 having a twisted shape is transported, the second support mechanism 38 can be made to appropriately follow the blade 8. By providing this second support mechanism 38, it is possible to ensure the effectiveness of cutting processing for the blade 8 regardless of the difference in the path line or the shape of the blade 8.

[0056] Furthermore, the cutting machine system 2 according to this embodiment includes an alignment member 39 that aligns the position of the blade 8 relative to the cutting machine 37. Therefore, by moving the feed trailer 50 backward so that the end face 8a of the blade 8 is kept in contact with the alignment member 39, the blade 8 being sent to the cutting machine 37 can be accommodated in the cutting area of ​​the cutting machine 37. This makes it easy to position the blade 8 relative to the cutting machine 37.

[0057] In the embodiment described above, the feed trailer 50 is moved backward so that the end face 8a of the blade 8 is kept in contact with the alignment member 39 so that the blade 8 fed to the cutter 37 is contained within the cutting area of ​​the cutter 37. However, the positioning of the blade 8 relative to the cutter 37 is not limited to this method.

[0058] 12 is an explanatory diagram showing a modified example of the cutting machine system. The cutting machine system 2 may include a tilting mechanism 43 that tilts the cutting machine unit, and this tilting mechanism 43 may tilt the cutting machine unit 35 so that the first support mechanism 36 is tilted downward toward the alignment member 39. This allows the blade 8 to maintain a state in which it is in contact with the alignment member 39 due to its own weight. The tilting mechanism 43 may be configured to tilt only the first support mechanism 36, in addition to tilting the entire cutting machine unit 35.

[0059] 13 is an explanatory diagram showing a modified example of the cutting machine system. The material feeder system 5 may be provided with a rotation mechanism 62 on the material feeder base 60, and the material feeder unit 65 may be rotated around a rotation axis along the vertical direction. This rotation mechanism 62 allows the longitudinal direction of the blade 8 to be offset with respect to the backward movement direction of the material feeder trailer 50. This allows the blade 8 to be kept in contact with the alignment member 39 by shifting the longitudinal direction of the blade 8 with respect to the backward movement direction of the material feeder trailer 50.

[0060] In this embodiment, the cutting machine system 2 further includes a first width-shifting mechanism 40 and a second width-shifting mechanism 41. Here, the first width-shifting mechanism 40 fixes the blade 8 between the alignment member 39 and the first movable body 400 by moving a first movable body 400 provided at a position facing the alignment member 39 in the width direction intersecting with the material feed direction along the width direction. The second width-shifting mechanism 41 fixes the blade 8 between the pair of second movable bodies 410, 411 provided at positions facing each other in the width direction by moving the pair of second movable bodies 410, 411 toward each other along the width direction.

[0061] The blade 8 has a twisted shape, and simply supporting the underside of the blade 8 may cause the blade 8 to be unstable when cut by the cutter 37. In this regard, the cutter system 2 can fix the blade 8 from the left and right directions, so that cutting by the cutter 37 can be stably performed.

[0062] In the cutting machine system 2 according to this embodiment, a cutting machine base 30, which is a base material on which the elements constituting the cutting machine system 2 are mounted, is configured to be detachable from the cutting side trailer 20. The cutting machine base 30 includes a first fixed portion 31 to which a first fastening device 23 installed on the loading platform 21 is fixed.

[0063] According to this configuration, the cutting machine system 2 can be handled separately from the cutting side trailer 20. Also, since the cutting machine system 2 can be easily mounted on a general-purpose trailer equipped with the first fastening device 23, the cutting machine system 2 can be easily realized. Note that this effect is not limited to the cutting machine system 2, but is similar to the feed machine system 5.

[0064] In the cutting machine system 2 of this embodiment, the cutting machine 37 is a band saw in which a saw blade housing 370 equipped with a band saw blade 373 is configured so as to be freely rotatable in the vertical direction around a hinge axis 376 arranged parallel to the rotation axis of the drive wheel 371.

[0065] According to this configuration, when the blade 8 is placed by the crane, the saw blade housing 370 is rotated to the upper limit position, thereby preventing interference between the blade 8 and the saw blade housing 370. This allows the blade 8 to be easily placed by simply moving the crane up and down.

[0066] The material feeding machine system 5 of this embodiment includes a third support mechanism 66 that supports the blade 8, an abutment portion 67 against which the tip 8b of the blade 8 in the material feeding direction abuts, and a third width adjustment mechanism 68 that fixes the blade 8 between a pair of third movable bodies 680, 681 arranged at positions opposite each other in the width direction by moving the pair of third movable bodies 680, 681 toward each other along the width direction.

[0067] According to this configuration, the blade 8 placed so as to straddle between the cutting machine system 2 and the material feeder system 5 can be appropriately sent to the cutting machine system 2. This allows the cutting machine system 2 to cut the blade 8 into a plurality of materials to be cut.

[0068] Furthermore, the structure cutting method described in this embodiment has a common concept with the cutting operation of the blade 8 by the structure cutting system 1 described above, and achieves the same effects as the structure cutting system 1.

[0069] In the above-described embodiment, the cutting machine 37 is configured as a band saw. However, the cutting machine 37 may be a saw cutting machine such as a hacksaw machine that performs cutting processing using a hacksaw blade, other than the band saw, or may be a laser cutting machine that performs laser cutting processing. For example, the hacksaw machine is configured such that a saw blade housing equipped with a linear hacksaw blade that reciprocates along the longitudinal direction can be rotated up and down around a hinge shaft that is provided parallel to a direction perpendicular to the longitudinal direction of the hacksaw blade.

[0070] In the above-described embodiment, the cutting machine system 2 and the material feed machine system 5 are mounted on a trailer, but may be a vehicle other than a trailer that moves on land. Also, the cutting machine system 2 and the material feed machine system 5 may be mounted on a ship that moves on the ocean. It may also be a ship.

[0071] In the above-described embodiment, the blade 8 is shown as the structure to be cut by the structure cutting system 1. However, the structure may be a support column supporting a rotor made up of multiple blades in a wind power generation device, or any other large structure, in addition to the blade 8.

[0072] As described above, the embodiment of the present invention has been described, but the description and drawings forming a part of this disclosure should not be understood as limiting this invention. From this disclosure, various alternative embodiments, examples and operating techniques will become apparent to those skilled in the art. [Explanation of symbols]
