[0011] Hereinafter, embodiments of a movable multi-axle truck, a movable multi-axle truck system and a method for constructing a long large structure according to the present invention will be described with reference to the drawings. The present invention is not limited by this embodiment. In addition, constituent elements in the following embodiments include those that can be easily replaced by a person skilled in the art and those that are substantially identical.

[0012] Figure 1 is a diagram showing an example of the movable multi-axle truck system SYS according to the present embodiment. As shown in Figure 1, the movable multi-axle truck system SYS according to the present embodiment includes a plurality of movable multi-axle trucks 100. Specifically, the movable multi-axle truck system SYS according to the present embodiment includes a first movable multi-axle truck 100A and a second movable multi-axle truck 100B.

[0013] The first movable multi-axle truck 100A includes a truck body 10, a rotation mechanism 20, and a first guide mechanism (guide mechanism) 30. The second movable multi-axle truck 100B includes a truck body 10, a rotation mechanism 20, and a second guide mechanism (guide mechanism) 40.

[0014] The truck body 10 has a base 11 and wheels 12. The truck body 10 can carry structure portions 51 and 52 that constitute the long large structure 50. The structure portions 51 and 52 are divided portions of the long large structure 50. The long large structure 50 is formed by connecting the structure portions 51 and 52. In the present embodiment, as the long large structure 50, girders for bridges, elevated roads and the like will be described as examples. In this case, the structure portions 51 and 52 are girder portions that constitute the girder. Note that the long large structure 50 is not limited to girders, and may be other structures.

[0015] The rotation mechanism 20 is disposed on the base 11. The rotation mechanism 20 supports the structure portion 51 such that the structure portion 51 can rotate around a central axis AX along the vertical direction. Figure 2 is a plan view schematically showing the general shape of the rotation mechanism 20. As shown in Figure 2, the rotation mechanism 20 has a central shaft portion 21, a rotation guide portion 22, and a connecting portion 23.

[0016] The central shaft portion 21 is arranged at a position corresponding to the central axis AX. The rotation guide portions 22 are arranged at positions spaced apart by an equal predetermined distance L on both sides in the diametrical direction centered on the central axis AX, and guide the rotation of the structure portions 51 and 52. The connecting portions 23 connect the central shaft portion 21 and the respective rotation guide portions 22.

[0017] In the rotation mechanism 20, the rotation guide portions 22 are provided such that the predetermined distance L can be changed. Here, an embodiment of changing the predetermined distance L will be described. In the present embodiment, the central shaft portion 21 and the rotation guide portions 22 are connected by the connecting portions 23 such that the predetermined distances L (L1, L2, L3) are different from each other, and the rotation mechanism 20, in which a guide plate 64 corresponding to the predetermined distance L is installed on the rotation guide portion 22, is mounted on the carriage main body 10. In this configuration, the connecting portion 23 and the guide plate 64 of the rotation mechanism 20 mounted on the carriage main body 10 can be replaced to change the predetermined distance L. It should be noted that the connecting portion 23 may be formed to be extendable and retractable in the longitudinal direction of the structure portions 51 and 52, and the predetermined distance L may be changed by adjusting the dimension of the connecting portion 23 in the longitudinal direction.

[0018] With reference to FIG. 3A, FIG. 3B and FIG. 4, a specific configuration of the rotation guide portion 22 will be described. FIG. 3A is an enlarged view showing a part of FIG. 2. FIG. 3B is a diagram showing an example of a state in which the structure portions 51 and 52 side has rotated from the state in FIG. 3A. FIG. 4 is a diagram showing a configuration along the A-A cross section in FIG. 3A. As shown in FIG. 3A, FIG. 3B and FIG. 4, the rotation guide portion 22 includes a carriage-side base plate 61, a rotation base plate 62, a sliding plate 63, a guide plate 64, and a guide rod 65.

[0019] The carriage-side base plate 61 is fixed to the upper surface of the carriage main body 10. A girder-side base plate 67 is fixed to the structure portions 51 and 52, and interlocks with the rotation base plate 62 in the rotation direction. The sliding plate 63 is arranged between the carriage-side base plate 61 and the rotation base plate 62. For example, two sliding plates 63 may be arranged in a stacked state in the vertical direction. The sliding plate 63 receives the load of the rotation base plate 62 and slides the rotation base plate 62 relative to the carriage-side base plate 61 in the rotation direction.

[0020] The guide plate 64 is detachably provided in the opening 62a of the rotating base plate 62. The guide plate 64 is positioned in accordance with the guide rod 65, which will be described later. In this embodiment, for example, multiple (two) guide plates 64 are arranged in the left-right direction. The guide plate 64 is provided with a through hole 64a that is aligned with the circumferential direction of a circle centered on the central axis AX. The through hole 64a penetrates the guide plate 64 in the vertical direction. The through hole 64a of the guide plate 64 is formed to align with a circle of diameter R centered on the central axis AX. The diameter R (R1, R2, R3) is set according to a predetermined distance L (L1, L2, L3). The rotating guide section 22 is provided with a guide plate 64 having a through hole 64a aligned with a circle of diameter R corresponding to a predetermined distance L.

[0021] The guide rod 65 is provided on the trolley-side base plate 61 and protrudes upward. The guide rod 65 is inserted into the through hole 64a of the guide plate 64. Multiple guide rods 65 (2 rods) are arranged, for example, in the left-right direction. The guide rod 65 is formed on the common intersection of circles of diameter R, which are arranged on the trajectory of a circle of diameter R centered on the central axis AX, according to a predetermined distance L for the rotating guide section 22. The diameters R (R1, R2, R3) are set according to the predetermined distance L (L1, L2, L3). In this embodiment, as the structural parts 51 and 52 rotate relative to the trolley body 10, the rotating base plate 62 and the guide plate 64 move in the rotational direction together with the structural parts 51 and 52 (see Figure 3B). At this time, the guide plate 64 moves relative to the guide rod 65 so that the guide rod 65 is aligned with the through hole 64a. In this way, the rotating guide section 22 guides the rotation of the structural parts 51 and 52 by the relative movement of the guide plate 64 and the guide rod 65 as the structural parts 51 and 52 rotate. The structural parts 51 and 52 can rotate with a stroke corresponding to the dimensions in which the through hole 64a is formed. In this case, the relative movement of the guide plate 64 and the guide rod 65 is restricted at both ends of the through hole 64a in the direction of rotation. That is, both ends of the through hole 64a in the direction of rotation can be made to function as stoppers that restrict the rotation of the structural parts 51 and 52.

[0022] Furthermore, a lifting mechanism 25 is provided between the rotating base plate 62 and the girder-side base plate 67. The lifting mechanism 25 is arranged, for example, one on each side of the longitudinal direction of the structural parts 51 and 52 with respect to the central axis AX. The lifting mechanism 25 adjusts the vertical dimension between the rotating base plate 62 and the structural parts 51 and 52. This allows the lifting mechanism 25 to adjust the vertical height position of the structural parts 51 and 52 relative to the trolley body 10. For example, a vertical jack mechanism can be used as the lifting mechanism 25.

[0023] Furthermore, a rotational force application mechanism 26 is provided between the trolley-side base plate 61 and the rotating base plate 62. The rotational force application mechanism 26 applies rotational force to the structural parts 51 and 52 about a central axis AX. The rotational force application mechanism 26 has a first link portion 26a fixed to the trolley-side base plate 61, a second link portion 26b fixed to the rotating base plate 62, and a horizontal jack portion 26c connected between the first link portion 26a and the second link portion 26b. The horizontal jack portion 26c is provided so as to be extendable and retractable in the horizontal direction. When the horizontal jack portion 26c extends and retracts, a force is generated in the extension / retraction direction (linear direction), and this force acts on the first link portion 26a and the second link portion 26b, thereby providing an auxiliary relative rotational force about a central axis AX between the trolley-side base plate 61 and the rotating base plate 62.

[0024] The first guide mechanism 30 is detachably attached to the first end 51a in the longitudinal direction of the structural portion 51. The first guide mechanism 30 guides the second end 52a of another structural portion 52 that is connected to the structural portion 51. The first guide mechanism 30 has, for example, a protrusion 31 that projects longitudinally from the first end 51a as a guide portion.

[0025] The second guide mechanism 40 is detachably provided on the second end 52a in the longitudinal direction of the structural portion 52. The second guide mechanism 40 guides the first end 51a of the structural portion 51 that connects to the structural portion 52. The second guide mechanism 40 has, as a guide portion, a recess 41 that is recessed in the longitudinal direction from the second end 52a.

[0026] In the above configuration of the first guide mechanism 30 and the second guide mechanism 40, by inserting the protrusion 31 into the recess 41, the first guide mechanism 30 can guide the second end 52a of the structural portion 52, and the second guide mechanism 40 can guide the first end 51a of the structural portion 51. In this way, by inserting the protrusion 31 into the recess 41, the first guide mechanism 30 and the second guide mechanism 40 can guide each other.

[0027] Next, an example of a method for constructing a long structure using the above-described mobile multi-axle trolley will be explained. Figure 5 is a flowchart of an example of a method for constructing a long structure according to this embodiment. Figures 6 to 11 are schematic diagrams showing an example of each step of the method for constructing a long structure according to this embodiment. As shown in Figure 5, the method for constructing a long structure according to this embodiment includes an assembly step S10, a mounting step S20, an adjustment step S30, a mounting step S40, and a coupling step S50.

[0028] As shown in Figure 6, assembly step S10 involves separately assembling multiple structural parts 51 and 52 that constitute the long structure 50. The following explanation will use the example of a case where the long structure 50 consists of two structural parts, 51 and 52. Note that the number of structural parts may be three or more. Each structural part 51 and 52 can be assembled in a different location. In assembly step S10, the structural parts 51 and 52 can be assembled, for example, on a frame 15 that provides sufficient height for a mobile multi-axle trolley 100 to enter.

[0029] As shown in Figure 7, the mounting process S20 involves mounting the first guide mechanism 30 to the first end 51a in the longitudinal direction of one structural part 51, and mounting the second guide mechanism 40 to the second end 52a in the longitudinal direction of the other structural part 52. The first guide mechanism 30 and the second guide mechanism 40 are arranged such that, for example, two protrusions 31 and two recesses 41 are at the same interval in the short direction.

[0030] In adjustment step S30, as shown in Figure 8, a predetermined distance L of the rotating mechanism 20 of the mobile multi-axle trolley 100 corresponding to the respective structural parts 51 and 52 is adjusted according to the longitudinal dimensions of the structural parts 51 and 52. In this embodiment, a rotating mechanism 20 is prepared in advance in which a central shaft part 21 and a rotating guide part 22 are connected by a connecting part 23 so that the predetermined distance L of each part is different. In adjustment step S30, the predetermined distance L of the rotating mechanism 20 is adjusted by attaching the rotating mechanism 20 to the trolley body 10. The rotating mechanism 20 also has a rotating guide part 22 having through holes 64a in the guide plate 64 that correspond to circles of different diameters centered on the central axis AX. This makes it possible to position a guide plate 64 having through holes 64a that correspond to circles of diameters corresponding to the predetermined distance L.

[0031] In the mounting process S40, as shown in Figure 9, the respective structural parts 51 and 52 are mounted on different mobile multi-axle carriages 100. Specifically, the structural part 51 with the first guide mechanism 30 attached is mounted on the first mobile multi-axle carriage 100A, and the structural part 52 with the second guide mechanism 40 attached is mounted on the second mobile multi-axle carriage 100B. In the mounting process S40, for example, each mobile multi-axle carriage 100 can be moved below the structural parts 51 and 52 to mount them so that they receive the structural parts 51 and 52 from the frame 15.

[0032] In the coupling process S50, as shown in Figure 10, the first mobile multi-axle carriage 100A, which is carrying the structural part 51, and the second mobile multi-axle carriage 100B, which is carrying the structural part 52, are moved relative to each other. As a result of this movement, as shown in Figure 11, the rotation mechanism 20 rotates each structural part 51 and 52 around the central axis AX so that the first guide mechanism 30 is guided by the second guide mechanism 40, and connects the first end 51a of the structural part 51 and the second end 52a of the structural part 52. This connects the structural part 51 and the structural part 52. With the structural parts 51 and 52 connected, a long structure 50, which is a connected body of multiple structural parts 51 and 52, is constructed. After the long structure 50 is constructed, the first guide mechanism 30 and the second guide mechanism 40 are removed.

[0033] In the example shown in Figures 10 and 11, first, the first mobile multi-axle carriage 100A and the second mobile multi-axle carriage 100B are positioned such that one of the first guide mechanism 30 of structural part 51 and the second guide mechanism 40 of structural part 52 is facing the other. Then, from this position, the first mobile multi-axle carriage 100A and the second mobile multi-axle carriage 100B are moved closer to each other. In the example shown in Figures 10 and 11, the case in which the first mobile multi-axle carriage 100A is moved is given as an example, but the method is not limited to this case, and the second mobile multi-axle carriage 100B may be moved, or both the first mobile multi-axle carriage 100A and the second mobile multi-axle carriage 100B may be moved. This relative movement causes the structural parts 51 and 52 to rotate around the central axis AX by the rotation mechanism 20 so that the two protrusions 31 of the first guide mechanism 30 attempt to fit into the two recesses 41 of the second guide mechanism 40. With the two protrusions 31 fitted into the two recesses 41, the first end 51a of the structural part 51 and the second end 52a of the structural part 52 are positioned at the appropriate connection position.

[0034] In this way, by linking the guidance of the first guide mechanism 30 and the second guide mechanism 40 with the rotation of the structural parts 51 and 52 by the rotation mechanism 20, the structural parts 51 and 52 can be appropriately positioned simply by moving the mobile multi-axle trolleys 100 on which the structural parts 51 and 52 are mounted closer to each other. In addition, in the coupling process S50, the rotation force application mechanism 26 may be used to apply an auxiliary rotational force to the structural parts 51 and 52 in the rotational direction around the central axis AX. In this case, the rotation of the rotation mechanism 20 can be performed smoothly.

[0035] As described above, the mobile multi-axle trolley 100 according to this embodiment is a mobile multi-axle trolley 100 capable of loading structural parts 51 and 52 that constitute a long structure 50, and comprises a trolley body 10, a rotation mechanism 20 provided on the trolley body 10 and supporting the structural parts 51 and 52 so that they can rotate around a central axis AX in the vertical direction, and a guide mechanism (30, 40) detachably provided at one end of the structural parts 51 and 52 in the longitudinal direction and guiding the other end of the structural parts 51 and 52 that are connected to the structural parts 51 and 52, and the rotation mechanism 20 has rotation guide parts 22 that are arranged on both sides in the diametrical direction around the central axis AX at positions separated by an equal predetermined distance L each, and the rotation guide parts 22 are provided so that the predetermined distance L can be changed.

[0036] With this configuration, the rotation guide 22 in the rotation mechanism 20 is provided such that a predetermined distance L can be changed, allowing the structural parts 51 and 52 to be supported and rotated at a position corresponding to the longitudinal dimension of the structural parts 51 and 52. This allows the structural parts 51 and 52 to be stably supported, enabling proper positioning.

[0037] In the mobile multi-axle trolley 100 according to this embodiment, the rotation mechanism 20 has a central shaft portion 21 positioned at a location corresponding to the central axis AX, and a connecting portion 23 that connects the central shaft portion 21 to each of the rotation guide portions 22.

[0038] With this configuration, since the rotating guide portion 22 and the central shaft portion 21 are connected by the connecting portion 23, a stable rotating mechanism 20 can be obtained.

[0039] In the mobile multi-axis trolley 100 according to this embodiment, the trolley body 10 is equipped with a rotating mechanism 20 in which a central shaft portion 21 and a rotating guide portion 22 are connected by a connecting portion 23 such that they are at different predetermined distances L from each other.

[0040] With this configuration, the rotating mechanism 20, in which the rotating guide portion 22 is positioned at a predetermined distance L corresponding to the longitudinal dimension of the structural portion 51, can be used appropriately.

[0041] In the mobile multi-axle trolley 100 according to this embodiment, the rotating guide section 22 is plate-shaped and has a through hole 64a along the circumferential direction of a circle centered on the central axis AX. It is connected to structural parts 51 and 52 and is provided to move integrally with the structural parts 51 and 52 in the rotational direction around the central axis AX. It also includes a guide plate 64 and a guide rod 65 inserted into the through hole 64a.

[0042] With this configuration, the guide rod 65 moves relative to the guide plate 64 along the through hole 64a, thereby properly guiding the rotation of the structural parts 51 and 52.

[0043] In the mobile multi-axle trolley 100 according to this embodiment, the rotation mechanism 20 has through holes 64a in the guide plate 64 corresponding to circles of different diameters centered on the central axis AX, and a rotation guide section 22 is arranged which has been replaced with a guide plate 64 corresponding to a predetermined distance.

[0044] With this configuration, by selecting one guide plate 64 from among several guide plates 64 and placing it on the rotating guide unit 22, guide plates 64 with through holes 64a corresponding to a predetermined distance L can be appropriately positioned.

[0045] In the mobile multi-axle trolley 100 according to this embodiment, the rotating guide section 22 includes a trolley-side base plate 61 fixed to the trolley body 10 side, a rotating base plate 62 fixed to the structural parts 51 and 52 side, a girder-side base plate 67 that is linked to the rotating base plate 62 in the rotational direction, and a sliding plate 63 positioned between the trolley-side base plate 61 and the rotating base plate 62, and rotation is restricted by a guide rod 65 and a guide plate 64.

[0046] With this configuration, the guide plate 64 is fixed to the structural parts 51 and 52 via the rotating base plate 62, and the guide rod 65 is fixed to the trolley body 10 via the trolley-side base plate 61. Since the rotation is restricted by the guide rod 65 and the guide plate 64, the rotation of the structural parts 51 and 52 relative to the trolley body 10 can be properly guided.

[0047] The mobile multi-axle trolley 100 according to this embodiment further includes a lifting mechanism 25 provided between the rotating base plate 62 and the girder-side base plate 67, which supports the structural parts 51 and 52 so that they can be raised and lowered.

[0048] With this configuration, the height of the structural parts 51 and 52 can be appropriately adjusted by the lifting mechanism 25.

[0049] The mobile multi-axle trolley 100 according to this embodiment further includes a rotational force application mechanism 26 that applies rotational force in the rotational direction about the central axis AX to the structural parts 51 and 52.

[0050] With this configuration, the rotational force application mechanism 26 can provide auxiliary rotational force to the structural parts 51 and 52.

[0051] The mobile multi-axle carriage system SYS according to this embodiment comprises a first mobile multi-axle carriage 100A and a second mobile multi-axle carriage 100B, and a first guide mechanism 30, which is a guide mechanism provided at one end of a structural portion 51 mounted on the first mobile multi-axle carriage 100A, and a second guide mechanism 40, which is a guide mechanism provided at one end of another structural portion 52 mounted on the second mobile multi-axle carriage 100B, are formed to guide each other.

[0052] With this configuration, by linking the mutual guidance of the first guide mechanism 30 and the second guide mechanism 40 with the rotation of the structural parts 51 and 52 by the rotation mechanism 20, the structural parts 51 and 52 can be properly positioned simply by moving the mobile multi-axle trolleys 100 on which the structural parts 51 and 52 are mounted closer to each other.

[0053] The method for constructing a long structure according to this embodiment includes an assembly step S10 in which each of the multiple structural parts 51 and 52 constituting the long structure 50 is assembled separately; an attachment step S20 in which the guide mechanisms (30 and 40) of the mobile multi-axle trolley 100 are attached to one end of each of the multiple structural parts 51 and 52 in the longitudinal direction; an adjustment step S30 in which a predetermined distance L of the rotation mechanism 20 of the mobile multi-axle trolley 100 corresponding to each of the structural parts 51 and 52 is adjusted according to the longitudinal dimensions of each structural part 51 and 52; and each The process includes a mounting step S40 in which structural parts 51 and 52 are mounted on the rotating mechanism 20 of the mobile multi-axle carriage 100, and a connecting step S50 in which the mobile multi-axle carriages 100 mounted on the structural parts 51 and 52 are moved relative to each other, and the rotating mechanism 20 rotates each structural part 51 and 52 about the central axis AX so that their respective guide mechanisms (30 and 40) guide each other, thereby connecting the multiple structural parts 51 and 52 together and constructing a long structure 50 which is a connected body of multiple structural parts 51 and 52.

[0054] With this configuration, by moving the mobile multi-axle trolleys 100, each equipped with separately assembled structural parts 51 and 52, relative to each other to connect multiple structural parts 51 and 52, a long structure 50, which is a connected body of multiple structural parts 51 and 52, can be easily constructed. In this case, in order to adjust a predetermined distance L of the rotation mechanism 20 of the mobile multi-axle trolley 100 corresponding to the structural parts 51 and 52 according to the longitudinal dimensions of the structural parts 51 and 52, the structural parts 51 and 52 can be supported and rotated at a position corresponding to the longitudinal dimensions of the structural parts 51 and 52. As a result, the structural parts 51 and 52 can be stably supported, and their positioning can be performed appropriately. [Explanation of Symbols]
