DETAILED DESCRIPTION OF THE INVENTION

[0008] (First embodiment) A first embodiment of a panel replacement assist system and a mobile body equipped with the panel replacement assist system will be described with reference to Figures 1 to 19. The mobile body is used when performing panel replacement work to replace existing sound-insulating panels that constitute sound-insulating walls on expressways, general roads, etc. with new panels. In the following, when there is no need to distinguish between existing and new panels, they will simply be referred to as sound-insulating panels. Furthermore, sound-insulating panels loaded on the mobile body are referred to as loaded panels. Furthermore, the direction in which the mobile body moves forward is defined as the forward direction, and the direction perpendicular to the forward-backward and left-right directions is defined as the up-down direction.

[0009] (Overview of the moving object) As shown in FIG. 1, a mobile object 10 has, for example, a tractor 11 and a trailer 12. The tractor 11 has a body frame 13 extending in the longitudinal direction. A cab 14 is mounted on the front of the body frame 13. A driving power source constituted by, for example, an engine or a motor / generator is mounted on the body frame 13. Steering wheels 15A are provided on the body frame 13 below the cab 14, and driving wheels 15B are provided behind the cab 14. A trailer 12 is connected to the body frame 13 via a coupler (not shown).

[0010] The trailer 12 has a base 16 and wheels 17. The base 16 is generally rectangular, and is connected at its front to the body frame 13. The base 16 functions as a loading platform for the mobile body 10. The wheels 17 are provided at the rear of the base 16. A load-lifting unit 25 is mounted on the base 16. The load-lifting unit 25 is used to lift the sound-insulating panel and transport it to a predetermined position.

[0011] (Load lifting unit) The load hoisting unit 25 includes a frame body 30, a front transport unit 51, and a rear transport unit 52. The frame body 30 is made up of a support 31, a lower frame body 32, and an upper frame body 33.

[0012] Each support column 31 extends upward from each corner of the platform 16. Each support column 31 is configured to be extendable and scalable by a plurality of support columns. In this embodiment, each support column 31 has a double-tube structure having a cylindrical lower support column 31A and a cylindrical upper support column 31B that is inserted into the lower support column 31A and can move forward and backward relative to the lower support column 31A. The lower support column 31A and the upper support column 31B are configured from, for example, square steel pipes.

[0013] Each support pillar 31 stores the upper support pillar portion 31B in the lower support pillar portion 31A while the mobile body 10 is traveling, thereby keeping the vehicle height of the mobile body 10 low, including the load lifting unit 25. Furthermore, at the construction site, each support pillar 31 is adjusted to a height suitable for panel replacement for the load lifting unit 25.

[0014] In the pair of support columns 31 located on the front side and the pair of support columns 31 located on the rear side, the upper ends of the lower support columns 31A are connected by a connecting frame 31C, which increases the mechanical strength of the frame body 30, for example, the strength when the support columns 31 are extended.

[0015] Each support column 31 is connected to the platform 16 via a jack 35 fixed to the lower end of the lower support column portion 31A. The jack 35 is configured to be extendable and retractable in the direction in which the support column 31 extends. By selectively extending and retracting the jack 35, the relative height of the load lifting unit 25 can be adjusted in the front-rear and left-right directions of the moving body 10.

[0016] The lower frame body 32 is composed of multiple frames arranged to connect the lower ends of the support columns 31. The lower frame body 32 has a front lower frame 36, a rear lower frame 37, a right lower frame 38, and a left lower frame 39. Each of the frames 36-39 is composed of square steel pipes, H-shaped steel, I-shaped steel, or steel material with a channel-shaped cross section that opens laterally. The front lower frame 36 connects a pair of support columns 31 located on the front side. The rear lower frame 37 connects a pair of support columns 31 located on the rear side. The right lower frame 38 connects a pair of front and rear support columns 31 located on the right side. The left lower frame 39 connects a pair of front and rear support columns 31 located on the left side. Each of the frames 36-39 is connected to the lower support column portion 31A of each support column 31 by various joining methods, such as welding or fastening using bolts and nuts.

[0017] In this embodiment, the right lower frame 38 is made of square steel pipes. A scaffolding plate 40 is attached to the right lower frame 38. The scaffolding plate 40 forms a scaffold for workers who are performing work to remove existing panels or install new panels. The scaffolding plate 40 is formed in the shape of a long plate that is approximately the same length as the length of the load lifting unit 25 in the front-to-rear direction. The scaffolding plate 40 is attached via a hinge 41 and is configured to be rotatable with respect to the right lower frame 38. The scaffolding plate 40 is configured to be foldable and stored toward the load lifting unit 25 side when the mobile body 10 is traveling, and to be unfoldable horizontally when panel replacement work is performed.

[0018] The upper frame body 33 is connected to the upper ends of the support columns 31. The upper frame body 33 includes a pair of left and right running rails 45, a front upper frame 46, and a rear upper frame 47.

[0019] The pair of left and right traveling rails 45 extend in the front-to-rear direction of the mobile body 10 and face each other in the left-to-right direction of the mobile body 10. The pair of left and right traveling rails 45 are made of, for example, H-shaped steel or I-shaped steel. The left traveling rail 45 is suspended between the upper ends of a pair of front and rear support columns 31 located on the left side of the mobile body 10. The right traveling rail 45 is suspended between the upper ends of a pair of front and rear support columns 31 located on the right side of the mobile body 10. These traveling rails 45 are connected to the upper ends of the support columns 31 by various joining methods such as welding or fastening using bolts and nuts.

[0020] The front upper frame 46 and the rear upper frame 47 are made of square steel pipes, H-shaped steel, I-shaped steel, or steel material with a channel-shaped (C-shaped) cross section that opens laterally. The front upper frame 46 connects the upper ends of a pair of left and right support columns 31 located on the front side. The rear upper frame 47 connects the upper ends of a pair of left and right support columns 31 located on the rear side. These frames 46, 47 are connected to their respective connected objects by various joining methods such as welding or fastening with bolts and nuts.

[0021] (Transport unit) Each of the front conveying unit 51 and the rear conveying unit 52 has a beam 53. The beam 53 is suspended from each traveling rail 45 via a suspension mechanism 55. The beam 53 is made of, for example, an H-shaped steel or an I-shaped steel. The beam 53 is longer than the distance between the pair of left and right traveling rails 45 and is formed to a length that allows the beams 53 of each conveying unit 51, 52 to be stored inside the frame body 30 (see FIG. 3). The beam 53 is configured to be movable along each traveling rail 45 and to be able to move back and forth along the extending direction of the beam 53 by the suspension mechanism 55 attached to each traveling rail 45.

[0022] A balance frame 57 is suspended from the beam 53 via a load-lifting plain trolley 56. The balance frame 57 is configured so that it can travel along the beam 53 using the load-lifting plain trolley 56. Lifting devices 58, such as chain blocks, capable of holding sound-insulating panels are provided on both ends of the balance frame 57. By operating the lifting devices 58 while holding the sound-insulating panel, the sound-insulating panel can be raised and lowered.

[0023] As shown in FIG. 2, the suspension mechanism 55 has an upper plain trolley 61 that can travel on each traveling rail 45 and a lower plain trolley 62 that can travel on the beam 53. The upper plain trolley 61 comprises a pair of plates 63 facing each other across the running rail 45, a connecting shaft 64 connecting the pair of plates 63, and rollers 65 rotatably supported on each plate 63 and rolling on the lower flange surface of the running rail 45.

[0024] The lower plain trolley 62 comprises a pair of plates 68 facing each other across the beam 53, a connecting shaft 69 connecting each plate 68, and rollers 70 rotatably supported on each plate 68 and rolling on the upper flange surface of the beam 53.

[0025] The upper plain trolley 61 and the lower plain trolley 62 have their connecting shafts 64, 69 connected by a connecting member 71. The connecting member 71 is a rotary joint formed by a swivel, a double swivel, or the like. The connecting member 71 is configured so that an upper connecting portion 71A attached to the connecting shaft 64 and a lower connecting portion 71B attached to the connecting shaft 69 can rotate relative to each other. The connecting member 71 connects the upper plain trolley 61 and the lower plain trolley 62 so that they can rotate relative to each other, with the vertical direction as the center of rotation. In other words, in the suspension mechanism 55, the upper connecting portion 71A and the lower connecting portion 71B of the connecting member 71 rotate relative to each other, thereby smoothly tilting the beam 53 in the horizontal direction relative to each traveling rail 45.

[0026] The suspension mechanism 55 also has a stopper 74 and a locking mechanism 75. The stoppers 74 are provided at both ends of the beam 53. The stoppers 74 prevent each plain trolley 56, 62 from falling off the beam 53. The locking mechanism 75 is configured to be attachable and detachable to the beam 53 using bolts or the like. The locking mechanism 75 is configured, for example, from an angle bar with a substantially L-shaped cross section. The locking mechanism 75 clamps the lower plain trolley 62 between the stopper 74 and the locking mechanism 75, restricting the movement of the lower plain trolley 62 relative to the beam 53, thereby restricting the movement of the beam 53 in its extension direction. When the left lower plain trolley 62 is locked by the locking mechanism 75, the beam 53 is prevented from extending to the left of the movable body 10. When the right lower plain trolley 62 is locked by the locking mechanism 75, the beam 53 is prevented from extending to the right of the movable body 10.

[0027] (Beam extension movement) The extending operation of the beam 53 will be described with reference to FIGS. 3 to 5, using the beam 53 of the front transport unit 51.

[0028] 3, the load lifting unit 25 is configured so that the beams 53 of each transport unit 51, 52 can be stored between a pair of left and right traveling rails 45. From this state, the lower plain trolley 62 of the hanging mechanism 55 attached to the left traveling rail 45 is locked with the locking mechanism 75, and then the beam 53 is rotated in the R direction, thereby starting the extension of the beam 53 to the right side of the moving body 10.

[0029] As shown in Figure 4, when the beam 53 is rotated in the R direction, the left end of the beam 53 is moved backward along the running rail 45 by the upper plain trolley 61 of the hanging mechanism 55, while the locking mechanism 75 prevents it from protruding to the left of the running rail 45.

[0030] Meanwhile, the right end of the beam 53 is moved forward on the traveling rail 45 by the upper plain trolley 61 of the hanging mechanism 55 attached to the right traveling rail 45. At this time, the lower plain trolley 62 of the hanging mechanism 55 travels on the beam 53, so that the right end of the beam 53 is sent out to the right of the traveling rail 45 along the extension direction of the beam 53.

[0031] 5, when the beam 53 is rotated 90 degrees relative to the traveling rail 45, the beam 53 is extended to the maximum extent to the right of the traveling rail 45. The load hoisting unit 25 is configured to be able to transport the sound-insulating panel between desired positions on the side of the movable body 10 by rotating the beam 53 in the R direction or by moving the beam 53 along the traveling rail 45.

[0032] (About the loading of soundproofing panels on moving objects) As shown in FIG. 6 , the sound-insulating panels are stored in racks 80 arranged on the platform 16 and loaded onto the mobile body 10. In this embodiment, the platform 16 has a plurality of racks 80 arranged in a matrix of two rows in the left-right direction and four rows in the front-to-back direction, so as to be positioned inside the lower frame body 32 of the load-lifting unit 25. The area in which each rack 80 is arranged is referred to as rack area A. With regard to rack area A, the right side in the left-to-right direction is referred to as the first row, the left side is referred to as the second row, and the frontmost row in the front-to-back direction is referred to as the first row, and the rearmost row is referred to as the fourth row. For example, rack area A11 refers to the frontmost row on the right side, and rack area A13 refers to the third row from the front on the right side. The racks 80 are made by connecting various steel materials using various joining methods.

[0033] As shown in Figure 7, the rack 80 has a generally box-like shape that is long in the front-to-rear direction and open at the top. The rack 80 is configured to be able to store multiple sound-insulating panels P (three in Figure 7). Each sound-insulating panel P is stored in the rack 80 so that its lower end is supported by the bottom surface 80B of the rack 80. The rack 80 is also configured so that the right side surface 80R, which is located on the side of the scaffold plate 40 that forms the scaffold for recovery and installation work, is lower than the left side surface 80L. This makes it possible to reduce the height of the load-lifting unit 25 that is required when loading and unloading the sound-insulating panel P into and out of the rack 80.

[0034] (mobility aid) 8, the mount 16 is provided with a movement assist device 90 that assists in the movement of the sound-insulating panel P on the mount 16. The movement assist device 90 assists in the movement of the rack 80, thereby assisting in the movement of the sound-insulating panel P on the mount 16. The movement assist device 90 has a left-right movement assist device 91 and a front-rear movement assist device 92.

[0035] (Left and right movement assist device) 8 and 9, the left-right movement assisting device 91 assists in the movement of the rack 80 in the left-right direction. The left-right movement assisting device 91 has a pair of left and right drive rollers 93 and a pair of front and rear driven rollers 94 that are provided to correspond to each rack area A of the rack 80. The drive rollers 93 and the driven rollers 94 extend in the front-to-rear direction. The drive rollers 93 and the driven rollers 94 are supported by the base 16 so that they can rotate around the front-to-rear direction as a rotation center, and their upper ends are positioned above the top surface (floor surface) of the base 16.

[0036] The pair of left and right drive rollers 93 are configured to be able to support the ends of the rack 80 in the left-right direction in each rack area A. The drive rollers 93 are driven to rotate by power supplied from a power supply device 98, which will be described later. The pair of front and rear driven rollers 94 are configured to be able to support the central portion of the rack 80 in the left-right direction. The pair of front and rear driven rollers 94 rotate in conjunction with the movement of the rack 80 in the left-right direction.

[0037] (back and forth movement auxiliary machine) 8 and 9, the longitudinal movement assisting devices 92 assist the movement of the rack 80 in the longitudinal direction. The longitudinal movement assisting devices 92 are arranged side by side in the left-right direction. The longitudinal movement assisting devices 92 include a drive roller 95, a driven roller 96, and an elevating mechanism 97.

[0038] The drive roller 95 and the driven roller 96 extend in the left-right direction. The drive roller 95 and the driven roller 96 are supported by an elevating mechanism 97 so as to be rotatable about the left-right direction as a rotation center. The drive roller 95 is disposed between adjacent rack areas A in the front-rear direction. The drive roller 95 is driven to rotate by power supplied from a power supply device 98, which will be described later. The driven roller 96 is disposed at a position surrounded by a pair of left and right drive rollers 93 and a pair of front and rear driven rollers 94, which are provided to correspond to each rack area A. The driven roller 96 rotates in accordance with the movement of the rack 80 in the front-rear direction.

[0039] The lifting mechanism 97 is provided inside the stand 16. The lifting mechanism 97 is configured to be able to raise and lower the drive roller 95 and the driven roller 96 between a standby position and an operating position. The standby position is a position where the upper ends of the drive roller 95 and the driven roller 96 are located lower than the upper ends of the drive roller 93 and the driven roller 94 that constitute the left-right movement assist device 91 (see FIG. 8). When power is supplied from the power supply device 98, the lifting mechanism 97 raises the drive roller 95 and the driven roller 96 from the standby position to the operating position. When the supply of power from the power supply device 98 is cut off, the lifting mechanism 97 lowers the drive roller 95 and the driven roller 96 from the operating position to the standby position.

[0040] 10, the operating position is a position where the upper ends of the drive roller 95 and the driven roller 96 are located higher than the upper ends of the drive roller 93 and the driven roller 94 that constitute the left-right movement assisting device 91. As a result, the rack 80 is supported by the drive roller 95 and the driven roller 96, which makes it easier for the rack 80 to move in the front-rear direction.

[0041] (Panel replacement procedure) An example of a procedure for panel replacement work in the first embodiment will be described with reference to FIGS.

[0042] 11 to 19, the rack area A where an empty rack 80 is placed is referred to as the "Empty" area. The rack area A where a rack 80 containing a newly installed panel is placed is referred to as the "N (New)" area, and the rack area A where a rack 80 containing an existing panel is placed is referred to as the "O (Old)" area.

[0043] First, as shown in Fig. 11, preparations for departure are carried out. In the preparations for departure, workers load a power supply device 98 (e.g., a hydraulic supply device) that supplies power to the left-right movement assist device 91, the front-rear movement assist device 92, etc., and a generator 99 that supplies power to lighting devices, etc., onto racks 80 arranged in rack area A11. In addition, workers use each transport unit 51, 52 to store new panels into racks 80 arranged in rack areas A13-A14, A21-A24. At this time, workers store into racks 80 the same number of soundproof panels as will be disposed between a pair of panel supports H (see Fig. 12). After the preparations for departure are completed, the mobile body departs for the construction site.

[0044] As shown in Fig. 12, at the construction site, a sound insulating wall is formed by panel supports H installed at a predetermined interval and existing panels Pa, Pb supported by a pair of adjacent panel supports H. Of the existing panels Pa, Pb, the panel to be replaced this time is the existing panel Pb.

[0045] When the mobile body 10 arrives at the construction site, the worker stops the mobile body 10 so that the rack area A11 is positioned in front of the existing panel Pb1 that is the target of the first retrieval work. Then, the worker performs construction preparation work.

[0046] In the construction preparation work, workers unfold the scaffolding plate 40, and then use the transport units 51, 52 to move the power supply device 98 and the generator 99 to the rear end of the scaffolding plate 40. The workers then connect the various wiring and piping to the power supply device 98 and the generator 99. With the power supply device 98 and the generator 99 moved, the rack area A11 becomes area "E".

[0047] When the construction preparation work is completed, the worker uses the front transport unit 51 to transport the existing panel Pb1 to the rack 80 in the rack area A11 and store it there, thereby causing the rack area A11 to become the "O" area (see FIG. 13).

[0048] 13, the worker moves the moving body 10 forward to a location where the rack area A13 is located in front of the area where the existing panel Pb1 was located and the rack area A12 is located in front of the existing panel Pb2 that will be the next target of the retrieval work.The worker then uses the rear transport unit 52 to perform installation work, transporting and installing the new panel Pc from the rack 80 in the rack area A13 to the area where the existing panel Pb1 was located.

[0049] The worker also uses the front transport unit 51 to transport the existing panel Pb2 to the rack 80 arranged in the rack area A12 and store it there, performing a retrieval operation. These installation and retrieval operations may be performed simultaneously by multiple workers.

[0050] As shown in FIG. 14, when the above-described installation and recovery work is completed, rack area A12 becomes area "O" and rack area A13 becomes area "E". Next, as shown in Figure 15, the worker operates the power supply device 98 to appropriately drive the drive rollers 93 of the left-right movement assisting machine 91, the drive rollers 95 of the front-rear movement assisting machine 92, and the lifting mechanism 97, thereby performing a rotation operation to move the rack 80 counterclockwise. As a result, rack area A12 becomes area "E," and rack area A13 becomes area "N." In other words, a loading space for the existing panels is created in rack area A12, which is located in front of the platform 16.

[0051] Next, as shown in Fig. 16, the worker advances the moving body 10 to a location where rack area A13 is placed in front of the portion where existing panel Pb2 was installed and rack area A12 is placed in front of existing panel Pb3, and then performs installation and removal work. Thereafter, the worker repeats the series of work described using Figs. 13 to 15 until rack area A14 becomes area "O" through the rotation work.

[0052] 17, when rack area A14 becomes area "O," the worker advances the moving body 10 to a location where rack area A13 will be placed in front of the portion where the existing panel Pb6 was installed. Then, the worker uses the rear transport unit 52 to perform the final installation work.

[0053] As shown in FIG. 18, when the final installation work is completed, the rack areas A12 and A13 become the "E" area, and the other rack areas A11, A14, A21 to A24 become the "O" area.

[0054] 19, the worker removes the wiring and piping connected to the generator 99 and the power supply device 98, and then uses the transport units 51, 52 to transport the generator 99 and the power supply device 98 to the rack 80 in the rack area A13 and store them there. The worker then folds the scaffolding plate 40, thereby completing the panel replacement work. Once the panel replacement work is complete, the mobile body 10 departs from the construction site.

[0055] The effects of the panel replacement assist system and the moving body of the first embodiment will be described. (1-1) The panel replacement assist system is composed of a hoisting unit 25 mounted on a platform 16 that functions as a loading platform for a mobile body, and a movement assist device 90. The hoisting unit 25 has a front transport unit 51 and a rear transport unit 52. The movement assist device 90 is configured to be able to form a loading space in front of the platform 16 for the existing panel transported by the front transport unit 51 by moving the sound-insulating panel using the space formed on the rear side of the platform 16 as the rear transport unit 52 transports the new panel.

[0056] With this configuration, the number of soundproof panels that can be loaded onto the mobile body 10 increases, allowing for more efficient panel replacement work. Also, the number of mobile bodies 10 that enter and leave the construction site can be reduced. Furthermore, while the mobile body 10 is parked, it is possible to simultaneously perform the work of removing the existing panels and the work of installing new panels, thereby further improving the efficiency of the panel replacement work.

[0057] (1-2) A plurality of racks 80 capable of storing sound-proofing panels are arranged in a matrix on the stand 16. The movement assist device 90 has a front-rear movement assisting device 92 that assists the movement of the racks 80 in the front-rear direction, and a left-right movement assisting device 91 that assists the movement of the racks 80 in the left-right direction. This configuration reduces the burden on workers when rotating the racks 80.

[0058] (1-3) The front-rear movement auxiliary machine 92 is provided with a lifting mechanism 97. The lifting mechanism 97 raises and lowers the rollers 95, 96 of the front-rear movement auxiliary machine 92 so that the bottom of the rack 80 moving in the front-rear direction is supported by the rollers 95, 96 of the front-rear movement auxiliary machine 92, and the bottom of the rack 80 moving in the left-right direction is supported by the rollers 93, 94 of the left-right movement auxiliary machine 91. This configuration can further reduce the burden on workers during rotation work.

[0059] (1-4) Furthermore, the lifting mechanism 97 is configured to be able to raise and lower the rollers 95, 96 of the forward / backward movement assisting device 92. As a result, when the moving body 10 is traveling, the bottom of each rack 80 is supported by the rollers 93, 94 of the left / right movement assisting device 91, so that movement of the rack 80 due to acceleration or braking of the moving body 10 can be suppressed.

[0060] (1-5) The left-right movement assisting machine 91 has a rotationally driven drive roller 93. The front-rear movement assisting machine 92 has a rotationally driven drive roller 95. This configuration can further reduce the burden on the worker during rotation work.

[0061] The first embodiment can be modified as follows: The first embodiment and the following modifications can be combined and implemented within the scope of technical compatibility. In the first embodiment, the mobility assistance device 90 may have a lifting mechanism that lifts the left-right mobility assistance device 91 instead of the forward-backward mobility assistance device 92. The mobility assistance device 90 may also have lifting mechanisms that lift the forward-backward mobility assistance device 92 and the left-right mobility assistance device 91 separately.

[0062] In the first embodiment, the movement assist device 90 does not have to have the left-right movement assist device 91 and the front-back movement assist device 92. In this case, by providing the rack 80 with wheels, the rack 80 can be easily moved on the stand 16.

[0063] In the first embodiment, the rack 80 storing the power supply device 98 and the generator 99 may be moved to the rear end of the scaffold plate 40 along with the rack 80. Also, the power supply device 98 and the generator 99 may be loaded onto the platform 16 without being stored in the rack 80. With this configuration, a space for one rack is formed on the platform 16, and rotation work can be performed by sequentially moving the racks 80.

[0064] (Second embodiment) A second embodiment of a panel replacement assist system and a mobile body equipped with the panel replacement assist system will be described with reference to Figures 20 to 32. Note that in the second embodiment, parts that differ from the first embodiment will be described in detail, and parts that are the same as those in the first embodiment will be denoted by the same reference numerals and will not be described in detail again.

[0065] (mobility aid) 20 and 21 , sound-insulating panels P are suspended from movement assist device 100 so as to be aligned in the front-to-rear direction and are loaded on stand 16. Movement assist device 100 has guide rails 101 and a movement suspension mechanism 102.

[0066] (guide rail) As shown in Figures 20 and 21, the guide rail 101 extends in the front-rear direction in an area inside the four support columns 31, below the lifters 110 of the transport units 51 and 52 (described later). The guide rail 101 is made of, for example, an H-beam or an I-beam. The guide rail 101 has a ring shape when viewed from above. The front end portion of the guide rail 101 is supported at the center of the front upper frame 46 via a front support frame 131 extending in the vertical direction. The rear end portion of the guide rail 101 is supported at the center of the rear upper frame 47 via a rear support frame 132 extending in the vertical direction. The guide rail 101 supports a plurality of travel suspension mechanisms 102.

[0067] As also shown in FIG. 22, the guide rail 101 has a movement rail 101a, a return movement rail 101b, a rear connection rail 101c, and a front connection rail 101d. The movement rail 101a extends in the front-rear direction from the center portion in the left-right direction. The movement rail 101a is used when moving the sound-insulating panel P suspended by the movement suspension mechanism 102 rearward.

[0068] Return rail 101b extends in the front-to-rear direction in an area opposite to the area where recovery and installation work is performed, that is, in this embodiment, an area to the left of moving rail 101a. Return rail 101b is used when moving moving suspension mechanism 102 from the rear to the front after sound-insulating panel P has been removed.

[0069] The rear connection rail 101c connects the rear end of the moving rail 101a and the rear end of the return rail 101b. The rear connection rail 101c is used when moving the moving suspension mechanism 102 from the moving rail 101a to the return rail 101b.

[0070] The front connection rail 101d connects the front end of the movement rail 101a and the front end of the return movement rail 101b. The front connection rail 101d is used when moving the movement suspension mechanism 102 from the return movement rail 101b to the movement rail 101a.

[0071] (Moving suspension mechanism) 20 and 21, the portable suspension mechanism 102 has the same basic structure as the load-hanging plain trolley 56. The portable suspension mechanism 102 is configured so that it can move around the guide rail 101 by rollers rolling on the lower flange surface of the guide rail 101. The portable suspension mechanism 102 is provided with a portable suspending tool 103.

[0072] 23, the transport suspending device 103 is formed in a bifurcated shape that extends downward from a base end connected to the transport suspension mechanism 102 and then branches into two, with a transport hook 106 provided at each tip. The transport suspending device 103 is formed in a shape that positions each transport hook 106 outside the guide rail 101 in the left-right direction. A clamp wire 104, which is a suspension auxiliary member that is detachably connected to the upper corner of the sound-insulating panel P, is hooked onto the transport hook 106. In this way, the sound-insulating panel P is loaded onto the mobile body 10 so as to be movable in the front-rear direction. Note that the suspension auxiliary member may be anything that can be hooked onto the hook, and may be made of a metal frame or the like.

[0073] (Transport unit) As shown in Figures 20 and 21, a lifter 110 is suspended from the beam 53 of each transport unit 51, 52 via a load-lifting plain trolley 56. The lifter 110 is configured to be movable along the extending direction of the beam 53 by the load-lifting plain trolley 56. A transport hoisting tool 111 is provided on the lifter 110. The transport hoisting tool 111 extends downward from a base end connected to the lifter 110, and is provided at its tip with a transport hook 112 (see Figure 21) on which the clamp wire 104 is hooked. The transport hoisting tool 111 has a bent shape that avoids interference with the transfer rail 101a when the lifter 110 is positioned directly above the transfer rail 101a of the guide rail 101, and allows the transport hook 112 to be positioned directly below the transfer rail 101a. That is, when the lifter 110 is positioned directly above the moving rail 101a, the transporting hoisting device 111 is configured to be able to hook the clamp wire 104, which is hung over the moving hook 106 of the transporting hoisting device 103, onto the transporting hook 112. The lifter 110 is configured to be able to raise and lower the sound-insulating panel P by operating it with the clamp wire 104 attached to the sound-insulating panel P hooked onto the transport hook 112.

[0074] (Panel replacement procedure) An example of a procedure for panel replacement work in the second embodiment will be described with reference to FIGS.

[0075] First, as shown in Fig. 24, preparations for departure are made. In the preparations for departure, workers load a power supply device 98 (e.g., a hydraulic supply device) that supplies power to various auxiliary equipment and a generator 99 that supplies power to lighting devices, etc., onto the front end of the platform 16. After connecting a clamp wire 104 to the newly installed panel, the workers use the transport units 51, 52 to load the newly installed panel behind the power supply device 98 and generator 99. After completing the preparations for departure, the mobile body 10 departs for the construction site.

[0076] 24 to 32, the rack 16 is divided into areas corresponding to the number of sound-insulating panels P supported by a pair of adjacent panel supports H. The "N (New)" area is an area where the corresponding number of newly installed panels are placed. The "O (Old)" area is an area where the corresponding number of existing panels are placed. The "E (Empty)" area is an area where the corresponding number of sound-insulating panels can be loaded. In addition, a mobile hoisting device 103 capable of suspending the existing panels is on standby at the front of the rack 16.

[0077] As shown in FIG. 25 , at the construction site, some of the existing panels have been removed according to the length of the mounting frame 16. Upon arriving at the construction site, the driver parks the mobile body 10 so that the front of the mounting frame 16 is positioned directly in front of the existing panel Pb1, which is the first target of the removal work. After the vehicle has stopped, construction preparation work is carried out. In the construction preparation work, workers unfold the scaffolding plate 40 and then use the transport units 51 and 52 to move the power supply device 98 and the generator 99 to the center of the scaffolding plate 40. The workers then connect various wiring and piping to the power supply device 98 and the generator 99. By moving the power supply device 98 and the generator 99, the front of the mounting frame 16 becomes area "E," creating a loading space for the existing panel Pb1.

[0078] Next, the worker operates the rear transport unit 52 as appropriate to sequentially transport the new panels in the "N" area located at the very rear of the platform 16 and install the new panels between a pair of panel supports H. The worker also operates the front transport unit 51 as appropriate to perform collection work, sequentially loading the existing panels Pb1 into the "E" area located at the very front of the platform 16.

[0079] During the installation work, the worker moves the lifter 110 directly above the moving rail 101a and directly above the new panel Pc to be transported. Next, the worker operates the lifter 110 to appropriately raise and lower the transport hoisting tool 111, and hooks the clamp wire 104 connected to the new panel Pc to be transported onto the transport hook 112.

[0080] Next, the worker transports the new panel suspended from the transport hoist 111 to the right side of the moving body 10, and then lowers the new panel so that it is inserted between the pair of panel supports H. This completes the installation of the new panel.

[0081] When the installation of the new panel is complete, the worker removes the clamp wire 104 from the new panel and then carries the clamp wire 104 to the vicinity of the front of the platform 16. The clamp wire 104 that has been carried to the vicinity of the front is attached to the existing panel during the retrieval work.

[0082] During the installation work, the worker moves the moving suspension mechanism 102 from which the new panel is suspended to the front of the moving rail 101a via the return rail 101b. Furthermore, the worker sequentially moves the other moving suspension mechanisms 102 from which new panels are suspended toward the rear. The worker performs this installation work for the required number of panels.

[0083] In the retrieval operation, the worker positions the lifter 110 directly above the existing panel Pb1 to be retrieved. Next, the worker attaches a clamp wire 104 to the existing panel Pb1, and then hooks the clamp wire 104 onto the transport hoist 111. After that, the worker transports the existing panel Pb1 suspended from the transport hoist 111 to area "E", and then hooks the clamp wire 104 connected to the existing panel Pb1 onto the moving hoist 103. This completes the retrieval of the existing panel Pb1. The worker performs this retrieval operation for the required number of panels.

[0084] As shown in Figure 26, when the installation and removal work is complete, the front of the platform 16 is area "O," the area one step behind the front is area "E," and the rest is area "N." Then, the worker sequentially moves the existing panel Pb1 loaded at the front of the platform 16 toward the rear. As a result, the front of the platform 16 becomes area "E," and a loading space for the existing panel Pb2 is created.

[0085] 27, the worker moves the moving body 10 forward to a location where the frontmost part (area "E") of the rack 16 is positioned in front of the existing panel Pb2 to be next removed. Then, the worker uses the rear transport unit 52 to install the new panel and the front transport unit 51 to remove the existing panel Pb2.

[0086] As shown in FIG. 28, when the installation work and the removal work are completed, the worker sequentially moves the existing panels Pb1 and Pb2 loaded in the "O" area toward the rear. 29, the front end of the platform 16 becomes area "E" again, forming a loading space for the existing panel Pb3. After that, the worker moves the mobile body 10 forward to a position where the front end of the platform 16 (area "E") is positioned in front of the existing panel Pb3 to be next collected, and then performs the installation and collection work again.

[0087] 30, the worker repeats the series of operations described with reference to FIGS. 25 to 29 until only the rearmost part of the platform 16 is in the "N" area. Then, the worker advances the mobile body 10 to a location where the frontmost part ("E" area) of the platform 16 is placed in front of the existing panel Pb7, and then performs the final installation and recovery operations.

[0088] As shown in Figure 31, once the final installation and retrieval work is completed, the worker moves the existing panel Pb7 that was loaded during the final retrieval work to the rear, forming area "E" at the front of the frame 16.

[0089] Then, as shown in FIG. 32, the worker removes the wiring and piping connected to the generator 99 and the power supply device 98, and then transports the generator 99 and the power supply device 98 to area "E" using the transport units 51, 52, etc. After that, the worker folds up the scaffolding plate 40. This completes the series of operations. Once the series of operations is completed, the mobile body 10 departs from the construction site for the maintenance site, with one of the workers as the driver.

[0090] The following describes the effects of the panel replacement assist system and the moving body according to the second embodiment. According to the second embodiment, in addition to the effect equivalent to (1-1) described in the first embodiment, the following effect can be obtained.

[0091] (2-1) The mobility assistance device 100 has a guide rail 101 including a mobility rail 101a extending in the forward / backward direction of the mobile body 10, and a plurality of mobility suspension mechanisms 102 configured to be able to suspend a sound-insulating panel P and movable along the guide rail 101.

[0092] This allows the soundproof panels to be stacked in a line in the front-to-rear direction on the mount 16. After the new panels are installed, the soundproof panels can be moved one by one to the rear of the mount 16, creating a loading space for the existing panels in front of the mount 16.

[0093] (2-2) The guide rail 101 is formed in a ring shape when viewed from above, and the movement suspension mechanism 102 is configured to be able to go around the guide rail 101. This allows portable suspension mechanism 102, from which the sound-insulating panel has been removed, to be smoothly moved to the front side of frame 16 without being removed from guide rail 101. It also prevents portable suspension mechanism 102 from falling off guide rail 101.

[0094] (2-3) The transportation suspension mechanism 102 is provided with a transportation suspender 103 formed in a bifurcated shape with a transportation hook 106 at its tip. The transport units 51 and 52 are also provided with a transportation suspender 111 with a transportation hook 112 at its tip. The transportation suspender 111 is formed in a bent shape so that the transportation hook 112 can be positioned directly below the transportation rail 101a.

[0095] This makes it possible to position the transport hook 112 between a pair of transport hooks 106, making it easy to transfer the clamp wire 104 between the transport suspender 103 and the transport suspender 111.

[0096] The second embodiment can be modified as follows: The second embodiment and the following modifications can be combined and implemented within the scope of no technical contradiction. As shown in FIG. 33 , in the second embodiment, the mobility assist device 100 may have a lower end support 120 that can support the lower ends of the loaded sound-insulating panels P. The lower end support 120 is biased upward by an elastic member 121. When moving the sound-insulating panels P, the lower end support 120 is stepped on by an operator, thereby releasing support for the sound-insulating panels P. This configuration can reduce the load acting on the guide rails 101. It can also suppress shaking of the sound-insulating panels P when the moving body 10 is traveling, for example.

[0097] 34, in the second embodiment, the guide rails 101 may be inclined so that the rear portions thereof are positioned lower. With this configuration, the sound-insulating panel P can be easily moved to the rear side of the mount 16.

[0098] In addition, in such a configuration, it is preferable that a regulating member 125 be provided on the moving rail 101a, in front of the position where the sound-insulating panel P to be transported during installation work is placed, to regulate the movement of the moving suspension mechanism 102 due to tilting.

[0099] As shown in FIG. 35, in the second embodiment, the guide rail 101 may have a moving rail 101a that is inclined so that the rear portion is positioned lower, and a returning rail 101b that is inclined so that the front portion is positioned lower.

[0100] With this configuration, the moving suspension mechanism 102 from which the new panel was suspended can be easily moved to the front end of the return rail 101b. Also, depending on the inclination angle of the return rail 101b, the moving suspension mechanism 102 can be moved automatically.

[0101] 36, the front connection rail 101d is provided so as to incline upward from the return movement rail 101b toward the movement rail 101a. The movement of the movement suspension mechanism 102 from the return movement rail 101b to the movement rail 101a via the front connection rail 101d is performed manually.

[0102] In the second embodiment, the sound-insulating panels mounted on the mount 16 may have their lower ends supported by the mount 16 by adjusting the height of the frame 30 . In the second embodiment, the guide rail 101 may be configured with only the movement rail 101a. In this case, the movement suspension mechanism 102 is configured to be detachable from the movement rail 101a.

[0103] In the second embodiment, the transport suspending tool 103 only needs to have a transport hook 106 at its tip, and its shape is not limited to a bifurcated shape. Also, the transport suspending tool 111 only needs to have a transport hook 112 at its tip, and its shape is not limited to a bent shape. [Explanation of symbols]
