Description

Technical Field

[0001] The present disclosure relates to a device for adjusting the position and orientation of wall-shaped concrete blocks used for installing wall-shaped concrete blocks such as concrete retaining walls in artificial ponds, etc., and an installation method.

Background Art

[0002] Conventionally, as a device used for installing a concrete retaining wall, a device for transporting and installing concrete blocks disclosed in Patent Document 1 has been proposed. This device transports and installs a concrete retaining wall and is composed of a loading platform section, a front operating section, and a rear operating section. By moving the transport and installation device such that the wheels of the front drive section ride on the bottom of the L-shaped concrete, the L-shaped concrete is positioned between the front drive section and the rear drive section, and then the L-shaped concrete is lifted and transported. Thereby, the transported L-shaped concrete is installed adjacent to the already installed L-shaped concrete. Also, when it can be lifted by a crane for construction, it is installed while being supported by a steel adjustment pedestal.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, with the conventional device for transporting and installing concrete blocks, since it is necessary to position the concrete blocks by the movement of the device itself, it is difficult to accurately install the concrete blocks. Although an L-shaped concrete retaining wall is cited as a wall-shaped concrete block, the same can be said for wall-shaped concrete blocks of other shapes as long as they are concrete structures.

[0005] The purpose of this disclosure is to provide a position and orientation adjustment device and installation method for wall-shaped concrete blocks that enable the precise installation of wall-shaped concrete blocks. [Means for solving the problem]

[0006] The first aspect of this disclosure is a position and orientation adjustment device applied when installing wall-shaped concrete blocks (100, 200) together, characterized in that it is placed on the forks (2a) of a forklift (2), supports a new block (100) to be installed together with an existing block (200) that has already been installed, and has an adjustment mechanism (3) that performs at least one of the orientation adjustment and position adjustment of the new block while the new block is being supported.

[0007] In this way, by allowing for posture and position adjustments of the newly installed blocks lifted by the forklift, the misalignment of the new blocks relative to the existing blocks can be reduced. This enables more precise installation.

[0008] For example, the adjustment mechanism can have a three-layer structure consisting of an upper layer, an intermediate layer, and a lower layer arranged in order in the vertical direction. In this case, the upper layer may be a support frame (10) that supports the newly installed block and mounts it onto a forklift, the intermediate layer may be a posture adjustment frame (20) that performs at least one of posture adjustment and position adjustment of the support frame that supports the newly installed block, and the lower layer may be a base frame (30) that is mounted on the forks and transmits the operation of the forks by the forklift.

[0009] This configuration allows for the adjustment of the posture and position of the support frame on the base frame using the posture adjustment frame, which in turn allows for the adjustment of the posture and position of the newly installed block supported by the support frame.

[0010] A second aspect of this disclosure is an installation method for wall-shaped concrete blocks (100, 200) to be installed together, characterized in that a position and orientation adjustment device (3) constituting an adjustment mechanism is placed on the forks (2a) of a forklift (2), a new block (100) to be installed together with an existing block (200) is lifted by the forklift via the position and orientation adjustment device, the new block is transported by the forklift and brought close to the existing block (200), and then at least one of the orientation adjustment and position adjustment of the new block is performed by the position and orientation adjustment device to align the new block with the existing block, and then the new block is installed adjacent to the existing block.

[0011] In this way, after lifting the new block with a forklift and bringing it close to the existing block, the new block's orientation and position can be adjusted using a position and orientation adjustment device, thereby aligning the new block with the existing block. This reduces the misalignment of the new block relative to the existing block, enabling highly accurate installation.

Mode for Carrying Out the Invention

[0014] Hereinafter, embodiments of the present disclosure will be described based on the drawings. In addition, among the other embodiments described below, parts that are the same or equivalent to each other in each embodiment will be described with the same reference numerals.

[0015] (First Embodiment) Referring to FIGS. 1 to 11, the retaining wall installation device 1 according to the first embodiment of the present disclosure will be described.

[0016] As shown in FIGS. 1 to 3, the retaining wall installation device 1 is configured by mounting a position and posture adjustment device 3 on the fork 2a of a forklift 2. Although details will be described later, the position and posture adjustment device 3 has a function of performing posture adjustment and position adjustment in a state where a new retaining wall 100 to be newly installed is lifted. After lifting the new retaining wall 100 supported by the position and posture adjustment device 3 by moving the fork 2a upward, it is transported near the existing retaining wall 200 by the forklift 2 and roughly positioned, and further, the retaining wall installation device 1 performs posture adjustment and position adjustment and installs it adjacent to the existing retaining wall 200. Thereby, it is possible to accurately install the new retaining wall 100 at a precise position and to accurately install a plurality of retaining walls side by side.

[0017] In FIGS. 1 to 8, the X-axis, Y-axis, and Z-axis are shown. The left-right direction of the forklift 2 is called the X-axis, the front-back direction of the forklift 2 orthogonal to the X-axis is called the Y-axis, and the up-down direction of the forklift 2 orthogonal to the X-axis and Y-axis is called the Z-axis. In the left-right direction of the X-axis in this embodiment, the left side when viewed from the front is the side where the pressure is applied to the retaining wall, and the side where the protrusion of the lower footing of the opposite retaining wall is large is the right side. The left-right direction of this device structure is determined by the load application direction of the retaining wall. Also, in this specification, there may be notations such as "along" the X-axis, Y-axis, and Z-axis, but it does not only indicate the direction parallel to the X-axis, Y-axis, and Z-axis, but also includes cases where it is generally in the same direction as each of these axes. Further, FIGS. 1 to 8 show the initial position of the position and attitude adjustment device 3, but it may be in a posture different from the initial position, and posture adjustment and position adjustment can be further performed from that posture.

[0018] <Configuration of the Position and Attitude Adjustment Device 3> As shown in FIG. 1, the position and attitude adjustment device 3 constitutes an adjustment mechanism that supports the newly constructed retaining wall 100 and enables lifting with the fork 2a, and performs attitude adjustment and position adjustment of the lifted newly constructed retaining wall 100. As the attitude adjustment, there is adjustment for rotation around the X-axis, Y-axis, and Z-axis. Here, all attitude adjustments are enabled, but only one of them may be sufficient. Hereinafter, the rotation around the X-axis is called pitching attitude adjustment, the rotation around the Y-axis is called rolling attitude adjustment, and the rotation around the Z-axis is called yawing attitude adjustment. As the position adjustment, there are adjustments in the left-right direction along the X-axis, the front-back direction along the Y-axis, and the up-down direction along the Z-axis direction. Here, all position adjustments are enabled, but only one of them may be sufficient. Hereinafter, the position adjustment in the front-back direction is called front-back slide operation, the position adjustment in the left-right direction is called left-right slide shift operation, and the position adjustment in the up-down direction is called up-down lifting operation.

[0019] Specifically, as shown in FIG. 3, the position and orientation adjustment device 3 has first to third sides 4 to 6 forming three sides of a substantially concave-shaped "concave" character, and is configured in a shape that is inserted from the front to the rear of the forklift 2. The first side 4 in the lateral direction is located on the backrest 2b side of the forklift 2 and is arranged along the X-axis. The left and right second and third sides 5 and 6 are located on both sides of the first side 4 and are arranged along the Y-axis at positions corresponding to the two forks 2a respectively. By inserting the forks 2a into the portions of the position and orientation adjustment device 3 that constitute the second and third sides 5 and 6, the position and orientation adjustment device 3 is mounted on the forklift 2. Specifically, as shown in FIG. 1, the position and orientation adjustment device 3 has a three-layer structure arranged vertically in order, and includes an upper support frame 10, a middle attitude adjustment frame 20, and a lower base frame 30. As shown in FIGS. 6 to 8, the support frame 10, the attitude adjustment frame 20, and the base frame 30 are all configured in a concave shape when viewed from above, and these are stacked in order to form the position and orientation adjustment device 3.

[0020] <Configuration of the support frame 10> The support frame 10 is a part that supports the newly installed retaining wall 100 and mounts it on the forklift 2. As shown in FIG. 6, the support frame 10 includes a body portion 11, a support pin 12, a support pin holding portion 13, a first slide portion 14, and an up-and-down adjustment receiving portion 15.

[0021] The body portion 11 is made of metal such as iron and has a concave shape. The body portion 11 has a back plate portion 111 that constitutes the first side 4 in the lateral direction, a first arm portion 112 that constitutes the second side 5 on the right side, and a second arm portion 113 that constitutes the third side 6 on the left side.

[0022] The back plate portion 111 is composed of a rectangular thick plate or a hollow plate. One surface on the backrest 2b side of the forklift 2 is generally along the XZ plane and is arranged at a predetermined distance from the backrest 2b.

[0023] The first arm portion 112 is positioned on the right side when the forklift 2 is viewed from the front, and its base end is joined to the back plate portion 111. The first arm portion 112 is roughly rectangular in shape and has an upper surface 112a, a lower surface 112b, an inner surface 112c, an outer surface 112d, and a tip surface 112e, as shown in Figures 5 and 6.

[0024] The upper surface 112a is arranged along the XY plane, and a support pin holding portion 13 is provided on the inner surface 112c side of the upper surface 112a.

[0025] The lower surface 112b is positioned along the XY plane and serves as a contact surface to which the tip of the rolling and pitching adjustment jack 34, described later, makes contact. Two first sliding parts 14 are fixed to the lower surface 112b, one at the front and one at the back, enabling connection between the support frame 10 and the attitude adjustment frame 20 and relative movement along the X-axis.

[0026] The inner surface 112c is aligned with the YZ plane and is positioned opposite the inner surface 113c of the second arm portion 113, which will be described later. It protrudes inward from the attitude adjustment frame 20, that is, towards the central position of both forks 2a. As the inner surface 112c protrudes beyond the attitude adjustment frame 20, the lower surface 112b also protrudes and is exposed from the attitude adjustment frame 20, and the tip of the rolling and pitching adjustment jack 34 is in contact with this exposed portion.

[0027] The outer surface 112d is positioned opposite the inner surface 112c as a surface that aligns with the YZ plane. Two clevises 16 are fixed to the outer surface 112d, aligned in the Y-axis direction. Each clevis 16 is connected to the movable end of each side shift jack 22, which will be described later.

[0028] The tip surface 112e is a plane that aligns with the XZ plane and is formed at a position that protrudes to the same extent as the attitude adjustment frame 20 in the Y-axis direction.

[0029] The second arm portion 113 is positioned on the left side when the forklift 2 is viewed from the front, and its base end is joined to the back plate portion 111. The second arm portion 113 is roughly rectangular in shape and has an upper surface 113a, a lower surface 113b, an inner surface 113c, an outer surface 113d, and a tip surface 113e, as shown in Figures 5 and 6.

[0030] The upper surface 113a is positioned along the XY plane and is at the same height as the upper surface 112a of the first arm portion 112. A support pin holder 13 is provided on the upper surface 113a at a position corresponding to the support pin holder 13 formed on the upper surface 112a of the first arm portion 112. The dimension of the upper surface 113a in the X-axis direction is arbitrary, but here it is made shorter than the upper surface 112a of the first arm portion 112.

[0031] The lower surface 113b is positioned along the XY plane and is at the same height as the lower surface 112b of the first arm portion 112. Two first sliding portions 14 are fixed to the lower surface 113b, one at the front and one at the back, enabling connection between the support frame 10 and the attitude adjustment frame 20 and relative movement along the X-axis. Furthermore, the lower surface 113b has an overhang portion 113ba that partially extends beyond the outer surface 113d. This overhang portion 113ba is the contact surface to which the tip of the lift-up jack 36, described later, makes contact. Both sides of the overhang portion 113ba in the Y-axis direction are reinforced by vertical walls along the XZ plane.

[0032] The inner surface 113c is aligned with the YZ plane and is positioned opposite the inner surface 112c of the first arm portion 112. The distance from the inner surface 113c to the inner surface 112c is greater than or equal to the thickness dimension of the intermediate cross-section of the newly constructed retaining wall 100, which is to be transported, when it is positioned within the recess of the position and attitude adjustment device 3.

[0033] The outer surface 113d is positioned opposite the inner surface 113c as a surface that aligns with the YZ plane. A vertical wall is erected on this outer surface 113d to reinforce the overhang 113ba.

[0034] The tip surface 113e is a plane that aligns with the XZ plane and is formed at a position that protrudes to the same extent as the tip surface 112e of the attitude adjustment frame 20 and the first arm portion 112 in the Y axis direction.

[0035] The support pins 12 are made of metal such as iron and are roughly cylindrical in shape. They support the new retaining wall 100 by being inserted into fitting holes 101 formed on both the front and back surfaces of the new retaining wall 100. The fitting holes 101 are holes formed in the new retaining wall 100 into which the male threads of the support pins 12 can be screwed in and fixed. When the new retaining wall 100 is poured with concrete in the factory, a component called an insert, which has a female thread formed in advance, is embedded in a predetermined position, thereby forming the fitting holes 101 in the predetermined position of the new retaining wall 100. The new retaining wall 100 is supported by the support pins 12 by screwing the male threads formed around the central axis of the support pins 12 into these fitting holes 101. The support pin 12 has a flange formed on one end that is fitted into the fitting hole 101, at a position approximately the same as the depth of the fitting hole 101, and on the other end, and the space between the two flanges is held by the support pin holding portion 13 provided on both arms of the first arm portion 112 and the second arm portion 113.

[0036] The support pin holder portion 13 is erected on the support frame 10 on the side opposite to the attitude adjustment frame 20 and holds the support pin 12. Here, the support pin holder portion 13 is constructed by erecting a plate material with notches at the upper ends of the upper surfaces 112a and 113a. The support pin 12 is fitted into and held in the notches at the upper ends of one of the opposing surfaces of both support pin holder portions 13. The two support pin holder portions 13 on the first arm portion 112 side and the second arm portion 113 side are aligned in the X-axis direction, but the positions of the upper end notches for holding the support pin 12 are spaced apart in the Y-axis direction.

[0037] The first slide section 14, together with the second slide section 23 provided on the attitude adjustment frame 20 (described later), constitutes a slide mechanism. Here, the slide mechanism is composed of slide guides, and as shown in Figure 4, the first slide section 14 is composed of C-shaped guides fixed to the lower surfaces 112b and 113b. The first slide section 14 has a linear opening through which the second slide section 23 is inserted, and the opening is positioned along the X-axis direction.

[0038] The vertical adjustment receiving portion 15 is formed by the protruding portion 113ba described above. The tip of the lift-up jack 36 is brought into contact with the protruding portion 113ba.

[0039] <Configuration of posture adjustment frame 20> The posture adjustment frame 20 is a part that performs at least one of the posture adjustment and position adjustment of the support frame 10 that supports the newly constructed retaining wall 100. As shown in Figure 7, the posture adjustment frame 20 includes a body part 21, a side shift jack 22, a second slide part 23, a guide part 24, and a reaction force receiving part 25, etc.

[0040] The body portion 21 is made of metal such as iron and is shaped like a "concave" corresponding to the support frame 10. The body portion 21 has a back plate portion 211 that forms the first horizontal side 4, a first arm portion 212 that forms the second right side 5, and a second arm portion 213 that forms the third left side 6.

[0041] The back plate portion 211 is made of a rectangular thick plate or hollow plate, and, similar to the back plate portion 111 of the support frame 10, one side of the back plate portion 211 on the side of the backrest 2b of the forklift 2 is roughly aligned with the XZ plane and positioned at a predetermined distance from the backrest 2b. For this reason, the back plate portion 211 and the back plate portion 111 overlap vertically.

[0042] The first arm portion 212 is positioned on the right side when the forklift 2 is viewed from the front, and its base end is joined to the back plate portion 211. The first arm portion 212 is roughly rectangular in shape and has an upper surface 212a, a lower surface 212b, an inner surface 212c, an outer surface 212d, and a tip surface 212e, as shown in Figures 5 and 7.

[0043] The upper surface 212a is positioned along the XY plane and has an overhang 212aa extending outwards from the second arm portion 213 at positions corresponding to the two clevises 16 provided on the support frame 10. A side shift jack 22 is fixed to the overhang 212aa. Two second sliding portions 23 are also fixed to the upper surface 212a, one at the front and one at the rear, enabling connection between the support frame 10 and the attitude adjustment frame 20 and relative movement along the X-axis. Both sides of the overhang 212aa in the Y-axis direction are reinforced by vertical walls along the XZ plane.

[0044] The lower surface 212b is positioned along the XY plane. The lower surface 212b is not connected to the base frame 30 located below it. Therefore, the attitude adjustment frame 20, together with the support frame 10, is able to move relative to the base frame 30 in the vertical direction. In this case, the lower surface 212b is positioned at a predetermined distance from the base frame 30.

[0045] The inner surface 212c is aligned with the YZ plane and is positioned opposite the inner surface 213c of the second arm portion 213, which will be described later, and is located on the side away from the center position of both forks 2a. Since the inner surface 212c is located outside the support frame 10, a space is provided below the support frame 10. The movable end of the rolling and pitching adjustment jack 34, which will be described later, is located in this space. The inner surface 212c is also provided with a second guide portion 242, which is part of the guide portion 24 for yawing attitude adjustment and front-to-back sliding operation, which will be described later.

[0046] The outer surface 212d is positioned opposite the inner surface 212c as a surface aligned with the YZ plane. Vertical walls reinforcing each protruding portion 212aa are erected on this outer surface 212d.

[0047] The tip surface 212e is a plane that aligns with the XZ plane and is formed at a position that protrudes to the same extent as the support frame 10 in the Y-axis direction. A clevis 26 is fixed to the tip surface 212e. The clevis 26 is connected to the movable end of the front-rear slide and yawing adjustment jack 32, which will be described later.

[0048] The second arm portion 213 is positioned on the left side when the forklift 2 is viewed from the front, and its base end is joined to the back plate portion 211. The second arm portion 213 is roughly rectangular in shape and has an upper surface 213a, a lower surface 213b, an inner surface 213c, an outer surface 213d, and a tip surface 213e, as shown in Figures 5 and 7.

[0049] The upper surface 213a is positioned along the XY plane and is at the same height as the upper surface 212a of the first arm portion 212. Two second sliding portions 23 are fixed to the upper surface 213a at the front and rear, enabling connection between the support frame 10 and the attitude adjustment frame 20 and relative movement along the X-axis. The X-axis dimension of the upper surface 213a is arbitrary, but here it is approximately the same as the portion of the upper surface 212a of the first arm portion 212a excluding the protruding portion 212aa, and is approximately the same as the upper surface 113a of the second arm portion 113 on the support frame 10.

[0050] The lower surface 213b is positioned along the XY plane and is at the same height as the lower surface 212b of the first arm portion 212. The lower surface 213b is also not connected to the base frame 30. Here, the lower surface 212b is at the same height as the lower surface 212b and is positioned at a predetermined distance from the base frame 30. The lower surface 213b is also provided with a first guide portion 241 and a reaction force receiving portion 25, which will be part of the guide portion 24 for yawing attitude adjustment and front-rear sliding operation described later. The adjustment pivot side roller receiver 33, which is provided on the upper surface 313a of the base frame 30, is in contact with the lower surface 213b.

[0051] The inner surface 213c is aligned with the YZ plane and is positioned opposite the inner surface 212c of the first arm portion 212. The distance from the inner surface 213c to the inner surface 212c is greater than or equal to the thickness dimension of the intermediate cross-section of the newly constructed retaining wall 100, which is to be transported, when it is positioned within the recess of the position and attitude adjustment device 3, and is also greater than the distance from the inner surface 113c to the inner surface 112c of the support frame 10.

[0052] The outer surface 213d is positioned opposite the inner surface 213c as a surface that aligns with the YZ plane.

[0053] The tip surface 213e is a plane that aligns with the XZ plane and is formed at a position that protrudes to the same extent as the support frame 10 in the Y-axis direction. A clevis 26 is also fixed to the tip surface 213e, and this clevis 26 is connected to the movable end of another front-to-back sliding and yawing adjustment jack 32.

[0054] The side shift jacks 22 perform the function of moving the support frame 10 relative to the attitude adjustment frame 20 in the direction along the X axis. The side shift jacks 22 are extendable and retractable in the direction along the X axis, and there are two of them arranged side by side in the Y axis direction, with a first jack 22a at the tip of the fork 2a and a second jack 22b at the base of the fork 2a. The movable ends of the first and second jacks 22a and 22b are connected to the clevis 16. The fixed ends of the first and second jacks 22a and 22b are fixed to the respective protruding parts 212aa. Therefore, by extending and retracting each side shift jack 22, the support frame 10 can be moved relative to the attitude adjustment frame 20 in the direction along the X axis, enabling left and right slide shift operation as described later.

[0055] The side shift jack 22 can be configured in any way, but a hydraulic jack is used here. When the side shift jack 22 is configured as a hydraulic jack, although not shown in the diagram, a piston connected to the movable end is placed inside the fixed end, and hydraulic hoses are connected to the back chambers on both sides of the piston's direction of movement. The movable end can be extended and retracted by controlling the inflow and outflow of hydraulic fluid from the hydraulic hoses to each back chamber using a drive solenoid valve.

[0056] The second slide portion 23, together with the first slide portion 14 provided on the support frame 10 described above, constitutes a sliding mechanism. Here, as shown in Figure 4, the second slide portion 23 is made up of a T-shaped guide fixed to the upper surfaces 212a and 213a. The T-shaped tip of the second slide portion 23 is inserted into the C-shaped first slide portion 14, which has a straight opening, allowing it to slide along the X-axis direction.

[0057] The guide section 24 functions as a guide during yawing attitude adjustment, and also functions as a guide for forward and backward sliding operation. Specifically, as shown in Figures 5 and 7, the guide section 24 has a first guide section 241 and a second guide section 242. The first guide section 241 is erected downward from the lower surface 213b of the second arm section 213 and has an arc-shaped section 241a and a straight section 241b. The second guide section 242 is provided on the inner surface 212c and has an arc-shaped section 242a and a straight section 242b.

[0058] Each of the arc-shaped sections 241a and 242a functions as a guide for adjusting the yawing attitude and is an arc centered at the center position C1 in Figure 7. The center position C1 can be set arbitrarily. However, it is preferable to align the left-right center line L1 of the forklift 2, as viewed from the front of the forklift 2, with a vertical line passing through the center of gravity Wc of the newly constructed retaining wall 100, and to align these lines with the center position C1.

[0059] Each linear section 241b and 242b is positioned closer to the base of the fork 2a than each arc-shaped section 241a and 242a, and is continuously connected to each arc-shaped section 241a and 242a. Each linear section 241b and 242b functions as a guide for the forward and backward sliding operation. The first guide section 241 and the second guide section 242 contact the adjustment pivot side roller receiver 33 and guide rod 35 provided on the base frame 30, respectively, as will be described later, thereby guiding yawing posture adjustment and forward and backward sliding operation.

[0060] The reaction force receiving section 25 is positioned on the opposite side of the adjustment pivot side roller receiver 33 from the first guide section 241. Together with the first guide section 241, it transmits the reaction force during the left and right slide shift operation accompanying the extension and retraction of the side shift jack 22 to the base frame 30 via the adjustment pivot side roller receiver 33. Here, the reaction force receiving section 25 is shaped like an arc to correspond to the trajectory of yawing attitude adjustment, and is an arc centered at the center position C1 in Figure 5.

[0061] <Configuration of base frame 30> The base frame 30 is mounted on the fork 2a and is the part that transmits the operation of the fork 2a by the forklift 2. As shown in Figure 8, the base frame 30 includes a body section 31, a front / rear slide and yawing adjustment jack 32, an adjustment pivot side roller receiver 33, a rolling and pitching adjustment jack 34, a guide rod 35, a lift-up jack 36, and the like.

[0062] The body section 31 is made of metal such as iron and is shaped like a "concave" sign, corresponding to the support frame 10 and the posture adjustment frame 20. The body section 31 has a back plate section 311 that forms the first horizontal side 4, a first arm section 312 that forms the second right side 5, and a second arm section 313 that forms the third left side 6.

[0063] The back plate portion 311 is made of a rectangular thick plate or hollow plate and is positioned so as to be in contact with the backrest 2b of the forklift 2, with one side of the back plate portion 311 roughly aligned with the XZ plane. The back plate portion 311 has openings in the Y-axis direction in the parts corresponding to the first arm portion 312 and the second arm portion 313, and the forks 2a are inserted into each of these openings.

[0064] The first arm portion 312 is positioned on the right side when the forklift 2 is viewed from the front, and its base end is connected to the back plate portion 311. The first arm portion 312 is roughly rectangular in shape and has an upper surface 312a, a lower surface 312b, an inner surface 312c, an outer surface 312d, and a tip surface 312e, as shown in Figures 5 and 8.

[0065] The upper surface 312a is positioned along the XY plane, and one side of the lower surface 312b side abuts against one of the forks 2a. The upper surface 312a has an overhang portion 312aa that partially extends inward beyond the inner surface 212c of the first arm portion 212 of the attitude adjustment frame 20. A rolling and pitching adjustment jack 34 and a guide rod 35 are provided on this overhang portion 312aa. Furthermore, both ends of the overhang portion 312aa in the Y-axis direction are reinforced by vertical walls along the XZ plane. The upper surface 312a also has an overhang portion 312ab that partially extends beyond the tip surface 312e in the Y-axis direction. A front-to-back slide and yawing adjustment jack 32 is provided on this overhang portion 312ab.

[0066] The lower surface 312b is positioned along the XY plane. The distance between the upper surface 312a and the lower surface 313b is arbitrary, but it is set to a distance that allows for the insertion of the fork 2a.

[0067] The inner surface 312c is aligned with the YZ plane and is positioned opposite the inner surface 313c of the second arm portion 313, which will be described later, and is located on the side away from the center position of both forks 2a. The aforementioned protruding portion 312aa protrudes from this inner surface 213c.

[0068] The outer surface 312d is positioned opposite the inner surface 312c as a surface aligned with the YZ plane. Both the inner surface 312c and the outer surface 312d protrude beyond the tip surface 312e in the Y-axis direction, reinforcing the protruding portion 312ab of the upper surface 312a.

[0069] The tip surface 312e is a plane that aligns with the XZ plane and is formed in a position that protrudes further than the support frame 10 and the attitude adjustment frame 20 in the Y-axis direction.

[0070] The second arm portion 313 is positioned on the left side when the forklift 2 is viewed from the front, and its base end is joined to the back plate portion 311. The second arm portion 313 is roughly rectangular in shape and has an upper surface 313a, a lower surface 313b, an inner surface 313c, an outer surface 313d, and a tip surface 313e, as shown in Figures 5 and 8.

[0071] The upper surface 313a is positioned along the XY plane and is at the same height as the upper surface 312a of the first arm portion 312, with one side of the lower surface 313b in contact with the other fork 2a. An adjustment pivot side roller receiver 33 is provided at approximately the center of the upper surface 312a in the Y-axis direction, corresponding to the space between the first guide portion 241 and the reaction force receiving portion 25. The upper surface 313a also has an overhang portion 313aa that partially extends outward beyond the outer surface 213d of the second arm portion 213 in the attitude adjustment frame 20. A lift-up jack 36 is provided on this overhang portion 313aa. Furthermore, both sides of the overhang portion 313aa in the Y-axis direction are reinforced by vertical walls along the XZ plane.

[0072] Furthermore, the upper surface 313a has an overhang portion 313ab that partially extends beyond the tip surface 313e in the Y-axis direction. This overhang portion 313ab is also equipped with a front-to-back sliding and yawing adjustment jack 32.

[0073] The lower surface 313b is positioned along the XY plane. The distance between the upper surface 312a and the lower surface 313b is arbitrary, but is set to allow for the insertion of the fork 2a. Also, the lower surface 313b is at the same height as the lower surface 312b of the first arm portion 312.

[0074] The inner surface 313c is aligned with the YZ plane and is positioned opposite the inner surface 312c of the first arm portion 312. The distance from the inner surface 313c to the overhang portion 312aa of the upper surface 312a of the first arm portion 312 is greater than or equal to the thickness dimension of the intermediate cross-section of the newly constructed retaining wall 100 to be transported, which is positioned within the recess of the position and attitude adjustment device 3.

[0075] The outer surface 313d is positioned opposite the inner surface 313c as a surface aligned with the YZ plane. A vertical wall is erected on this outer surface 113d to reinforce the overhang 313aa.

[0076] The tip surface 313e is a plane that aligns with the XZ plane and is formed in a position that protrudes beyond the support frame 10 and the attitude adjustment frame 20 in the Y-axis direction. The inner surface 313c and outer surface 313d protrude beyond the tip surface 313e in the Y-axis direction and reinforce the protruding portion 313ab of the upper surface 313a.

[0077] The front-to-back sliding and yawing adjustment jacks 32 are used for the front-to-back sliding operation and yawing attitude adjustment of the support frame 10 and attitude adjustment frame 20. The front-to-back sliding and yawing adjustment jacks 32 are extendable and retractable in the direction along the Y-axis and are provided at the tip positions of the first arm portion 312 and the second arm portion 313, respectively, so that two are arranged side by side in the X-axis direction. They consist of a first jack 32a on the first arm portion 312 side and a second jack 32b on the second arm portion 313 side. The movable ends of the first and second jacks 32a and 32b are connected to the clevis 26. The fixed ends of the first and second jacks 32a and 32b are supported by support portions 32aa and 32ba, respectively. Since the support parts 32aa and 32ba are rotatable around the Z-axis with respect to their central positions 32ab and 32bb, the first and second jacks 32a and 32b are similarly rotatable around the Z-axis with respect to their central positions 32ab and 32bb.

[0078] The front / rear sliding and yawing adjustment jack 32 can be configured in any way, but a hydraulic jack is used here. The configuration of the hydraulic jack can be the same as that of the side shift jack 22.

[0079] The adjustment pivot side roller bearing 33 is a spherical roller bearing (free bearing) that rotatably houses spherical rolling elements. The adjustment pivot side roller bearing 33 is fixed to the upper surface 313a and supports the second arm portion 213 of the attitude adjustment frame 20 with the tips of the rolling elements, enabling the attitude adjustment frame 20 to slide in various directions. Furthermore, during rolling and pitching attitude adjustments, it serves as a pivot point for the operation of the rolling and pitching adjustment jack 34.

[0080] The rolling and pitching adjustment jacks 34 are used for vertical movement, rolling adjustment, and pitching adjustment of the support frame 10 and the posture adjustment frame 20. The rolling and pitching adjustment jacks 34 are extendable and retractable along the Z-axis, and adjust the distance between the first arm portion 112 of the support frame 10 and the first arm portion 312 of the base frame 30. The rolling and pitching adjustment jacks 34 are arranged side by side in the Y-axis direction and consist of a first jack 34a located on the tip surface 312e side and a second jack 34b located on the back plate portion 311 side. The fixed ends of the first jacks 34a and 34b are fixed to the protruding portion 312aa of the first arm portion 312, and the movable ends are spherical roller receivers housing spherical rolling elements. The exposed tips of the rolling elements support the first arm portion 112 of the support frame 10, allowing the support frame 10 to slide in various directions.

[0081] The rolling and pitching adjustment jack 34 can be configured in any way, but a hydraulic jack is used here. The configuration of the hydraulic jack can be the same as that of the side shift jack 22, except that it is equipped with a spherical roller bearing at the tip.

[0082] The guide rod 35 contacts the second guide portion 242 provided on the first arm portion 212 of the attitude adjustment frame 20, and assists in yawing attitude adjustment and forward / backward sliding operation of the support frame 10 and the attitude adjustment frame 20. Here, the guide rod 35 is made up of a cylindrical rod that protrudes from the upper surface 312a of the first arm portion 312 along the Z-axis direction.

[0083] The lift-up jack 36 extends and retracts simultaneously with the rolling and pitching adjustment jack 34, providing three-point support for the vertical movement of the support frame 10 and the posture adjustment frame 20. The lift-up jack 36 is positioned in the Y-axis direction between the two rolling and pitching adjustment jacks 34, preferably in the center, and adjusts the distance between the second arm portion 113 of the support frame 10 and the second arm portion 313 of the base frame 30. The lift-up jack 36 has a configuration similar to, for example, the rolling and pitching adjustment jack 34. That is, the lift-up jack 36 is extendable and retractable in the direction along the Z-axis, with a fixed end fixed to the protruding portion 313aa of the second arm portion 313, and a movable end which is a spherical roller receiver housing spherical rolling elements. This allows the support frame 10 to slide in various directions while supporting the second arm portion 113 of the support frame 10 with the exposed tips of the rolling elements. When the support frame 10 and the posture adjustment frame 20 are raised and lowered, the guide rods 35 and the adjustment pivot side roller receivers 33 provided on the upper surfaces 312a and 313a of the base frame 30 come into contact with the first guide portion 241, the second guide portion 242, and the reaction force receiving portion 25 provided on the posture adjustment frame 20, and act as guides.

[0084] <Operation of retaining wall installation device 1 and position / attitude adjustment device 3: From mounting to rough positioning> Next, we will explain the operation of the retaining wall installation device 1 configured as described above. First, insert the fork 2a of the forklift 2 into the openings of the first arm portion 312 and the second arm portion 313 of the base frame 30 in the position and orientation adjustment device 3. At this time, or before mounting the next newly installed retaining wall 100 on the position and orientation adjustment device 3 after installing the retaining wall, it is preferable to set each frame of the position and orientation adjustment device 3 to the initial position shown in FIGS. 1 to 8, for example. At this position, the outer surfaces 112d, 212d, 312d of each first arm portion 112, 212, 312 are flush, and the outer surfaces 113d, 213d, 313d of each second arm portion 113, 213, 313 are flush. Also, the support frame 10, the attitude adjustment frame 20, and the base frame 30 are parallel to each other in terms of the upper surfaces 112a, 212a, 312a of each first arm portion 112, 212, 312 and the upper surfaces 113a, 213a, 313a of each second arm portion 113, 213, 313. This initial position is the neutral state before assembling the newly installed retaining wall 100.

[0085] After lifting the position and orientation adjustment device 3 with the fork 2a, move the forklift 2 toward the newly installed retaining wall 100, and fit the intermediate cross-section in which the support pins 12 are screwed into the fitting holes 101 on both sides of the newly installed retaining wall 100 into the recess of the position and orientation adjustment device 3 configured in a "concave" shape. As shown in FIGS. 9 and 10, the newly installed retaining wall 100 has an L shape with a height of several meters, for example, 4 m or more, and the thickness of the wall in the height direction gradually increases as it goes downward. Also, as shown in FIG. 2, the center of gravity Wc is located below half of the height dimension, and fitting holes 101 into which the support pins 12 are screwed are formed at a position higher than the center of gravity Wc. For this reason, before inserting the newly installed retaining wall 100 into the recess of the position and orientation adjustment device 3, it is preferable to move the fork 2a upward and position the position and orientation adjustment device 3 at a place higher than the center of gravity Wc.

[0086] With the support pins 12 already screwed into the fitting holes 101 on both sides of the new retaining wall 100, the crane moves the new retaining wall 100 from the transport vehicle to the main retaining wall installation device 1. Once the new retaining wall 100 is lifted upright by the crane, the forks 2a are raised to place the support pins 12 onto the support pin holding parts 13. This makes it possible to lift and transport the new retaining wall 100 using the forklift 2 via the position and posture adjustment device 3.

[0087] Next, the new retaining wall 100 is transported by forklift 2 and moved as shown in Figure 9 to be positioned next to the already installed existing retaining wall 200. At this time, it is difficult to transport the new retaining wall 100 in an exact position relative to the existing retaining wall 200, so the new retaining wall 100 is transported to a position, for example, a few centimeters away from the existing retaining wall 200. Then, the position and posture adjustment device 3 is used to perform rolling and pitching posture adjustment, yawing posture adjustment, left and right slide shift operation, front and back slide operation, and up and down lifting operation. Note that the posture adjustment etc. by the position and posture adjustment device 3 only needs to be performed in response to the misalignment between the new retaining wall 100 and the existing retaining wall 200, and it is not necessary to perform all adjustments and operations, but all adjustments and operations will be explained here.

[0088] <Rolling Pitching Posture Adjustment> Rolling and pitching posture adjustments are performed by operating two rolling and pitching adjustment jacks 34, which are installed on one side of the base frame 30.

[0089] The lower surface 112b of the first arm portion 112 of the support frame 10 is supported by the spherical roller bearings at the tips of the first jack 34a and the second jack 34b of the rolling and pitching adjustment jack 34. The lower surface 213b of the second arm portion 213 of the attitude adjustment frame 20 is supported by the adjustment pivot side roller bearing 33. In other words, the support frame 10 and the attitude adjustment frame 20 above the base frame 30 are supported by three spherical roller bearings. Therefore, by using the adjustment pivot side roller bearing 33 located on one side in the X-axis direction as a pivot point and operating the rolling and pitching adjustment jack 34 located on the other side, rolling and pitching attitude adjustment becomes possible.

[0090] When viewing forklift 2 from the front, extending the strokes of both the first jack 34a and the second jack 34b by the same amount allows for counterclockwise rolling posture adjustment with respect to the Y-axis. Conversely, reducing the strokes of both the first jack 34a and the second jack 34b by the same amount allows for clockwise rolling posture adjustment with respect to the Y-axis.

[0091] Furthermore, when viewed from the right side of the forklift 2, by using the adjustment pivot side roller receiver 33, which is located midway between the first jack 34a and the second jack 34b on one side in the X-axis direction, as a pivot point, the stroke of the first jack 34a is extended and the stroke of the second jack 34b is reduced, thereby enabling pitching posture adjustment in a clockwise direction relative to the X-axis. Conversely, by reducing the stroke of the first jack 34a and extending the stroke of the second jack 34b, pitching posture adjustment in a counterclockwise direction relative to the X-axis is possible. Since the formation positions of the upper end notches formed in the support pin holding portion 13 on the first arm portion 112 side and the second arm portion 113 side are spaced apart in the Y-axis direction, the newly constructed retaining wall 100 can be prevented from rotating.

[0092] <Yawing posture adjustment> Yaw position adjustment is performed by operating the front-to-back sliding and yawing adjustment jacks 32 located on the left and right sides of the front of the base frame 30.

[0093] When viewed from above, extending the stroke of the first jack 32a and reducing the stroke of the second jack 34b by the same amount as the first jack 32a allows for yawing posture adjustment in a counterclockwise direction relative to the Z-axis. Conversely, reducing the stroke of the first jack 32a and extending the stroke of the second jack 32b allows for yawing posture adjustment in a clockwise direction relative to the Z-axis. By extending and retracting the first jack 32a and the second jack 32b in opposite directions, the support frame 10 and the posture adjustment frame 20 can be rotated around the Z-axis relative to the base frame 30, thereby enabling yawing posture adjustment. Since the guide section 24 includes an arc-shaped portion 241a in the first guide section 241 and an arc-shaped portion 241a in the second guide section 242, yawing posture adjustment can be performed smoothly. Furthermore, the first and second jacks 32a and 32b of the front-to-back sliding and yawing adjustment jack 32 are each rotatable in the yawing direction. As a result, the first and second jacks 32a and 32b can be swung in accordance with the yawing attitude adjustment, enabling smoother yawing attitude adjustment.

[0094] <Left / Right slide shift operation> The left and right sliding shift operation is performed by operating the side shift jack 22 provided on one side of the base frame 30.

[0095] When viewed from the front of the forklift 2, extending the same stroke of the first and second jacks 22a and 22b on the right side in the same direction moves the support frame 10 to the left relative to the attitude adjustment frame 20. Conversely, reducing the stroke of the first and second jacks 22a and 22b moves the support frame 10 to the right relative to the attitude adjustment frame 20. This makes it possible to slide and shift the support frame 10 left and right relative to the attitude adjustment frame 20. Because it is equipped with a sliding mechanism consisting of a first sliding part 14 and a second sliding part 23, smooth left and right slide and shift operation is performed along the X-axis direction. In addition, the adjustment pivot side roller receiver 33 and the reaction force receiving part 25 or the first guide part 241 come into contact, and the guide rod 35 and the second guide part 242 come into contact, so that the reaction force load of the left and right slide and shift operation is received and transmitted to the forklift 2 via the base frame 30. Therefore, it is possible to move only the support frame 10 from side to side while suppressing the movement of the posture adjustment frame 20 from side to side relative to the base frame 30.

[0096] <Forward and backward sliding operation> The front-to-rear slide shift operation is performed by operating the front-to-rear slide and yawing adjustment jacks 32 located on the left and right sides of the front of the base frame 30. The front-to-rear slide and yawing adjustment jacks 32 are used for both yawing attitude adjustment and front-to-rear slide operation.

[0097] When viewed from above, extending the same stroke of the first and second jacks 32a and 32b in the same direction allows the support frame 10 and attitude adjustment frame 20 to slide backward relative to the base frame 30. Conversely, reducing the stroke of the first and second jacks 32a and 32b allows the support frame 10 and attitude adjustment frame 20 to slide forward relative to the base frame 30. This makes it possible to slide the support frame 10 and attitude adjustment frame 20 back and forth relative to the base frame 30. Since the guide section 24 is provided with a linear section 241b on the first guide section 241 and a linear section 241b on the second guide section 242, smooth back and forth sliding operation is performed along the Y-axis. Furthermore, when the support frame 10 and attitude adjustment frame 20 slide back and forth, they are supported at three points: two rolling and pitching adjustment jacks 34 provided on one side of the base frame 30 and the adjustment pivot side roller receiver 33.

[0098] <Up and down movement> The vertical lifting operation is performed by operating a lift-up jack 36 in a three-point support configuration, in addition to two rolling and pitching adjustment jacks 34 located on one side of the base frame 30.

[0099] Specifically, the two rolling and pitching adjustment jacks 34 and the lift-up jack 36 are extended and retracted in the same direction by the required lifting stroke to perform the vertical movement. If rolling and pitching posture adjustment is also required, the vertical movement may be performed simultaneously, but it is preferable to perform this after the posture control. The lifting amount of the two rolling and pitching adjustment jacks 34 should be the sum of the lifting amount for rolling and pitching posture adjustment and the lifting amount for the vertical movement, and the vertical movement of the two rolling and pitching adjustment jacks 34 and the lift-up jack 36 should be performed simultaneously after posture control.

[0100] As described above, once the left-right slide shift operation, up-down lifting operation, yawing posture adjustment, rolling / pitching posture adjustment, and front-to-back slide operation by the position and attitude adjustment device 3 are completed, the final installation of the newly constructed retaining wall 100, which was transported by the forklift 2, can be performed. That is, the newly constructed retaining wall 100 is installed adjacent to the existing retaining wall 200. Since the positional misalignment of the newly constructed retaining wall 100 relative to the existing retaining wall 200 has already been eliminated by the position and attitude adjustment device 3, the newly constructed retaining wall 100 can be installed precisely next to the existing retaining wall 200.

[0101] Furthermore, the newly constructed retaining wall 100 may not only be placed adjacent to the existing retaining wall 200, but may also be connected by providing fitting grooves 102 and 202 and joint sealing material 103 on adjacent sides, as shown in Figures 9 and 10. In the example in Figure 9, a fitting groove 202 is formed on one side of the existing retaining wall 200. The joint sealing material 103, which has been pre-fitted and installed in the fitting groove 102 of the new retaining wall 100 in the form shown in Figure 11, as shown in Figures 2 and 9, is fitted into this fitting groove 202. The fitting grooves 102 and 202 and the joint sealing material 103 are L-shaped, extending horizontally and vertically to match the side shape of each retaining wall 100 and 200, and provide sealing between the retaining walls. To fit the joint sealing material 103 into the fitting groove 202, it is necessary to adjust the three-dimensional orientation and installation position while checking the fitting state. In such cases, conventional devices like the one shown in Patent Document 1 are insufficient, and the joining and installation work requires considerable effort.

[0102] In contrast, by roughly positioning the new retaining wall 100 with a forklift 2 until just before fitting the joint sealant 103 attached to the new retaining wall 100 into the fitting groove 202 of the existing retaining wall 200, and then controlling the posture of the new retaining wall 100 with the position and posture adjustment device 3, the positional misalignment of the new retaining wall 100 relative to the existing retaining wall 200 can be reduced. Therefore, even in installation configurations that require assembly precision, such as fitting the joint sealant 103 into the fitting groove 202, accurate installation becomes possible. Consequently, the labor involved in the joint installation work between the new retaining wall 100 and the existing retaining wall 200 can be reduced, and the work time can be shortened. Furthermore, since the position and posture adjustment device 3 only needs to be attached to an existing forklift 2, its versatility can be increased.

[0103] Furthermore, in the conventional device shown in Patent Document 1, there is a concern that if the center of gravity is high due to a tall retaining wall, especially if the weight of the device is lighter than the retaining wall, it may tip over even with a small lateral force. In contrast, in this embodiment, the fitting holes 101 for the support pins 12 are formed at a position higher than the center of gravity Wc of the newly installed retaining wall 100. Therefore, the position and posture adjustment device 3 can lift the tall newly installed retaining wall 100 in a suspended state at a position higher than the center of gravity Wc. Consequently, even if a lateral force is applied to the newly installed retaining wall 100 while it is being loaded onto the forklift 2, the tipping of the newly installed retaining wall 100 on the forks 2a can be suppressed, improving safety during retaining wall installation. In addition, by making the vehicle weight of the forklift 2 heavier than the maximum load weight in order to balance the tipping with the maximum load weight of the forklift 2, the risk of tipping under the operating conditions of the forklift 2 can be further reduced.

[0104] (Other embodiments) This disclosure is written in accordance with the embodiments described above, but is not limited to those embodiments and includes various modifications and variations within the scope of equivalents. In addition, various combinations and forms, as well as other combinations and forms that include only one, more, or fewer of those elements, fall within the scope and concept of this disclosure.

[0105] While we have described the use of the position and orientation adjustment device 3 in the installation of a retaining wall, it can also be used, for example, in the installation of wall-shaped concrete blocks of other shapes. In other words, the position and orientation adjustment device 3 can be applied when installing new blocks alongside existing blocks to create wall-shaped concrete blocks.

[0106] Furthermore, in the above embodiment, the position and attitude adjustment device 3 was given as an example of a three-layer structure capable of rolling and pitching attitude adjustment, yawing attitude adjustment, left and right slide shift operation, front and back slide operation, and up and down lifting operation. However, this is merely one example, and it is sufficient if the structure can be attached to the forklift 2 and at least one of the various attitude controls, left and right slide shift operation, front and back slide operation, and up and down lifting operation can be performed before the new retaining wall 100 is installed relative to the existing retaining wall 200.

[0107] Furthermore, in the above embodiment, the arrangement of each part constituting the position and orientation adjustment device 3 is reversed left to right depending on the direction of the load application on the retaining wall. [Explanation of Symbols]
