Description

Technical Field

[0001] The present invention relates to a support device for an object to be mounted, which is used to support facilities such as a solar cell array installed on the ground and other objects to be mounted, and is capable of adjusting the angle of the object to be mounted in the installed state.

Background Art

[0002] When supporting an object to be mounted on the ground surface, such as a solar cell array (solar panel) installed on the ground, when a plurality of objects to be mounted are arranged on the ground, they are directly installed and fixed on the ground surface, and a plurality of support members for individually supporting the objects to be mounted are also arranged on the ground surface. Here, when the ground surface is not uniformly inclined with respect to the horizontal plane, such as when the ground surface is inclined with respect to the horizontal plane, the inclination angles of the plurality of support members with respect to the horizontal plane will not be constant.

[0003] When the object to be mounted is a solar cell array, in order to ensure that its power generation efficiency is above a certain level, regardless of the inclination angle of the support member, it is necessary to adjust the orientation of the surface of the solar cell array so that the inclination angle of the surface of the solar cell array with respect to the horizontal plane is constant. For this purpose, it is necessary that the inclination angle of the plane including the upper surface of the pedestal that supports the solar cell array and is supported on the support member on the ground surface can be freely adjusted with respect to the support member (see Patent Documents 1 to 5).

[0004] In order to make the angle of the upper surface of the pedestal adjustable, it is necessary to connect the receiving member (metalware), which is a component for supporting the pedestal on the support member, to the support member so that the angle can be adjusted, or to enable the receiving member to support the pedestal with an adjustable angle (Patent Documents 1 to 3).

[0005] When using a receiving member, elongated holes or a number of holes for height adjustment and horizontal position adjustment must be formed in the receiving member and the pedestal or support member to which it is connected, or an arcuate elongated hole for angle adjustment must be formed. As a result, the number of processes for the constituent members of the support device including the pedestal or support member increases, and the assembly tends to become complicated. Further, when adjusting the angle, since it is necessary to adjust the angle of the entire pedestal while supporting the entire pedestal, the stability and work efficiency during work are low.

[0006] The above becomes prominent when attempting two-axis angle adjustment of the inclination angle about an axis along the horizontal direction within the plane of the pedestal and the inclination angle about an axis along a direction perpendicular to the horizontal direction.

[0007] In Patent Document 4, the angle of the pedestal can be adjusted by interposing a link mechanism between the pedestal and the support member. However, in the method using the link mechanism, basically, only the inclination angle about an axis along the horizontal direction within the plane of the pedestal can be adjusted. If an attempt is made to adjust the inclination angle about an axis perpendicular to that direction (horizontal direction), the structure must be complicated because two-direction link mechanisms must be arranged to intersect.

[0008] In Patent Document 5, the angle of the pedestal can be adjusted by changing the length of the diagonal member for supporting the pedestal by the support member. However, even in this method, in order to enable two-axis angle adjustment, diagonal members with different lengths in two directions must be prepared, and it is necessary to replace the diagonal member every time the angle is changed, resulting in poor work efficiency.

[0010] In any of the above examples, if it is attempted to enable angle adjustment around two axes (two directions), it is inevitable to cause complication in the assembly of the support device components, complication in the structure, or deterioration in workability.

[0011] Based on the above background, the present invention proposes a support device for an upper load in a form that can simplify the structure while enabling angle adjustment around two axes (two directions). [Means for Solving the Problems]

[0012] The support device for an upper load according to the invention of claim 1 includes a lower adjustment member that is installed directly or indirectly on the ground surface and fixed to the ground, and an upper adjustment member that is butted against and connected to the lower adjustment member to support the upper load. The lower adjustment member has a lower plate fixed to the ground, an upper plate supported by the lower plate with a distance therebetween and forming a surface inclined with respect to the lower plate, and a lower support member joined to the lower plate and the upper plate to support the upper plate on the lower plate. The upper adjustment member has a lower plate connected to the upper plate of the lower adjustment member facing the upper plate, an upper plate supported by the lower plate of the upper adjustment member with a surface inclined with respect to the lower plate, and an upper support member joined to the lower plate and the upper plate of the upper adjustment member to support the upper plate on the lower plate. It is a constitutive requirement that the lower plate of the upper adjusting member is overlapped with the upper plate of the lower adjusting member such that the axial direction of the upper adjusting member faces an arbitrary direction with respect to the axial direction of the lower adjusting member.

[0013] The "lower adjusting member that is installed directly or indirectly on the ground surface and fixed to the ground" means that there are cases where the lower adjusting member is installed directly on the ground surface and fixed to the ground, and cases where the lower adjusting member is installed indirectly on the ground surface and fixed to the ground. In the latter case, as shown in FIG. 1, the lower adjusting member 2 is supported by being connected to the support member 4 that is installed directly on the ground surface 7 and fixed to the ground (Claim 4), and is indirectly fixed to the ground. The ground surface 7 is mainly a ground surface (including a slope) 7 inclined with respect to the horizontal plane, but may also be a horizontal plane.

[0014] The "upper adjusting member that is butted against and connected to the lower adjusting member and supports the object placed thereon" means that there are cases where the upper adjusting member 3 paired with the lower adjusting member 2 is directly butted against and connected to the lower adjusting member 2, and cases where some intermediate member is interposed between the upper adjusting member 3 and the lower adjusting member 2 and the upper adjusting member 3 is indirectly connected to the lower adjusting member 2. The upper adjusting member 3 may directly support the object placed thereon 6 or indirectly support it via the gantry 5 (Claim 2). The object placed thereon 6 refers to all objects that can be supported by the support device 4, such as equipment including a solar cell array (solar panel), an antenna, etc.

[0015] The "lower plate fixed to the ground" means that there are cases where the lower plate 21 constituting the lower adjusting member 2 is directly fixed to the ground, and cases where, as shown in FIG. 1, it is indirectly fixed to the ground by being connected (joined) to the support member 4 directly fixed to the ground (Claim 4).

[0016] The "upper plate that is spaced apart from the lower plate and is supported by the lower plate while forming a surface inclined with respect to the lower plate" means that the upper plate 22 of the lower adjustment member 2 is spaced apart from the lower plate 21 and forms a surface that is not parallel to the lower plate 21 and faces the lower plate 21, and is supported by the lower plate 21. Although the lower plate 21 and the upper plate 22 are basically flat plates, this is not necessarily required, and they may include curved surfaces.

[0017] The "lower support member that is joined to the lower plate and the upper plate and supports the upper plate on the lower plate" means that the lower support member 23 is interposed between the lower plate 21 and the upper plate 22 facing each other, and the lower support member 23 bears the load from the upper load 6 received by the upper plate 22 and transmits it to the lower plate 21. The lower adjustment member 2 is composed of at least the lower plate 21, the upper plate 22, and the lower support member 23 interposed therebetween. The "load received by the upper plate 22" refers to the load including the upper load 6 and the upper adjustment member 3. When a gantry 5 is interposed between the upper load 6 and the upper adjustment member 3 (Claim 2), it also includes the load of the gantry 5.

[0018] The "upper adjustment member has a lower plate that faces the upper plate of the lower adjustment member and is connected to the upper plate, and an upper plate that is supported by the lower plate of the upper adjustment member while forming a surface inclined with respect to the lower plate" means that the lower plate 31 of the upper adjustment member 3 faces the upper plate 22 of the lower adjustment member 2 and is directly or indirectly overlapped and connected (joined). At the same time, the upper plate 32 of the upper adjustment member 3, similar to the lower adjustment member 2, is spaced apart from the lower plate 31 of the upper adjustment member 3, forms a surface that is not parallel to the lower plate 31 and faces the lower plate 31, and is supported by the lower plate 31. Although the lower plate 31 and the upper plate 32 of the upper adjustment member 3 are basically flat plates, they may include curved surfaces.

[0019] "The upper adjusting member is joined to the lower plate and the upper plate of the upper adjusting member and has an upper support member that supports the upper plate on the lower plate." Similar to the lower adjusting member 2, an upper support member 33 is interposed between the lower plate 31 and the upper plate 32 of the upper adjusting member 3 that face each other, and while the upper support member 33 bears the load received by the upper plate 32, it is transmitted to the lower plate 31. It also means that the upper adjusting member 3 is composed of at least the upper support member 33 interposed between both the lower plate 31 and the upper plate 32. The "load received by the upper plate 32" refers to the load including the upper load 6. When a pedestal 5 is interposed between the upper load 6 and the upper adjusting member 3, it also includes the load of the pedestal 5.

[0020] "The lower plate of the upper adjusting member can be overlapped with the upper plate of the lower adjusting member such that the axial direction of the upper adjusting member faces an arbitrary direction with respect to the axial direction of the lower adjusting member." It means that the lower plate 31 of the upper adjusting member 3 overlaps directly or indirectly with the upper plate 22 of the lower adjusting member 2, but the axial direction of the upper adjusting member 3 is not in a fixed direction and overlaps with the upper plate 22 at an arbitrary angle with respect to the axial direction of the lower adjusting member 2. "Indirectly" means that an intermediate member is interposed between the lower plate 31 and the upper plate 22.

[0021] The lower plate 31 of the upper adjusting member 3 is overlapped with the upper plate 22 of the lower adjusting member 2 and connected (joined) to each other. The axial direction of the upper adjusting member 3 is the axial direction of the upper support member 33, which is the direction of the line passing through the center of the upper support member 33. The axial direction of the lower adjusting member 2 is also the axial direction of the lower support member 23, which is the direction of the line passing through the center of the lower support member 23.

[0022] "The axial direction of the upper adjusting member faces an arbitrary direction with respect to the axial direction of the lower adjusting member" means that, as shown in FIGS. 9-(a) to (e), including the case where the axial directions of the lower adjusting member 2 and the upper adjusting member 3 are located on the same line, they form an arbitrary angle with each other, and the lower plate 31 is butted against each upper plate 22.

[0023] This angle can be freely adjusted (set) according to the angle formed by the axial directions of the lower adjusting member 2 and the upper adjusting member 3 when they are combined. However, this angle is determined according to the angle formed by the upper plate 32 of the upper adjusting member 3 that supports the upper load 6 and the ground surface 7 (the lower plate 21 of the lower adjusting member 2). Basically, the lower plate 31 of the upper adjusting member 3 is overlapped with the upper plate 22 with the center of the lower plate 31 of the upper adjusting member 3 aligned with the center of the upper plate 22 of the lower adjusting member 2 that overlaps each other, but this is not necessarily required.

[0024] For example, as shown in FIG. 9, when the axial direction of the upper adjusting member 3 intersects the axial direction of the lower adjusting member 2 on the butting surface of both, and the lower plate 31 and the upper plate 22 overlap each other, by rotating the upper adjusting member 3 around the axial direction with respect to the lower adjusting member 2, when the support device 1 is viewed in a specific direction, a state can be obtained in which the axial direction of the upper adjusting member 3 forms an arbitrary angle with respect to the axial direction of the lower adjusting member 2. The "specific direction" is, for example, the direction in which the ground surface 7 is viewed so that the inclination angle θ of the ground surface 7 with respect to the horizontal plane is known, as shown in FIG. 1-(a).

[0025] The angle α shown in FIGS. 9-(a) and (b) indicates the angle formed by the ground surface 7 and the upper plate 32 on the upstream side on the ground surface 7 when the support device 1 is viewed so that the inclination angle θ of the ground surface 7 with respect to the horizontal plane is known, as shown in FIG. 1-(a), and shows the state adjusted so that the upper surface of the upper load 7 is horizontal according to the inclination angle θ of the ground surface 7. The angle β shown in FIGS. 9-(d) and (e) indicates the angle formed by the ground surface 7 and the upper plate 32 on the downstream side on the ground surface 7, and shows the state adjusted so that the upper surface of the upper load 7 is inclined by the inclination angle θ + angle β of the ground surface 7 with respect to the horizontal plane and rises from (a) and (b).

[0026] If the lower plate 31 of the upper adjusting member 3 is bolted to the upper plate 22 of the lower adjusting member 2, as shown in FIGS. 4-(c) and 5-(d), by forming insertion holes 22a and 31a through which the bolts pass at short intervals in the circumferential direction, it is possible to make the angle adjustment finer. If the insertion holes 22a and 31a are formed in the shape of long holes with a long length in the circumferential direction, further fine adjustment is possible.

[0027] As described above, the lower plate 31 of the upper adjusting member 3, which is a component of the support device 1, is overlapped and connected to the upper plate 22 of the lower adjusting member 2, which is also a component of the support device 1, with the axial directions of the respective adjusting members 2 and 3 facing arbitrary directions. By this connection, the angle formed between the axial direction of the lower adjusting member 2 and the axial direction of the upper adjusting member 3 can be freely adjusted (set). That is, the angles α and β formed between the lower plate 21 of the lower adjusting member 2 installed along the ground surface 7 and the upper plate 32 of the upper adjusting member 3 that supports the upper load 6 can be freely adjusted (set).

[0028] As a result, when adjusting the angle of the receiving member that directly supports the upper load with respect to the supporting member fixed to the ground (as in Patent Documents 1 to 3), processing for forming a large number of holes in the receiving member and the supporting member becomes unnecessary, and an angle adjustment operation while the gantry is being supported is not required, thus improving the working efficiency.

[0029] The combination of the lower adjusting member 2 and the upper adjusting member 3 has a simple structure of "a combination of two parts obtained by obliquely cutting a cylinder (cylindrical body)" as shown in Fig. 9-(c). However, it has the advantage that the angle formed between the lower plate 21 of the lower adjusting member 2 and the upper plate 32 of the upper adjusting member 3 can be freely adjusted by simply rotating the upper adjusting member 3 around its axis while the lower adjusting member 3 is fixed.

[0030] Although there are examples of using "parts obtained by obliquely cutting a cylinder" (Japanese Patent Laid-Open Nos. 5-309594 and 10-96444), there is no idea of adjusting the angle formed between the surfaces orthogonal to the respective axial directions by using a combination of two paired parts.

[0031] When the gantry 5 that directly supports the upper load 6 is supported by the upper adjusting member 3, the gantry 5 has a diagonal member 56 connected to and supported by the upper plate 32 of the upper adjusting member 3 on the lower surface side (Claim 2). The gantry 5 is assembled into, for example, a flat plate shape according to the form or shape of the upper load 6, and a diagonal member 56 for being supported by the upper plate 32 of the upper adjusting member 3 is connected (joined) to the lower surface side. The gantry 5 is connected (joined) to the upper plate 32 of the upper adjusting member 3 at the lower end portion of the diagonal member 56, and thus is supported by the upper adjusting member 3 and the lower adjusting member 2.

[0032] In this case, especially if the upper plate 32 of the upper adjusting member 3 is joined to the upper support member 33 at a position below the upper end surface of the upper support member 33 as shown in FIG. 5-(a) (Claim 3), when joining the lower end portion of the diagonal member 56 to the upper plate 32 of the upper adjusting member 3, by abutting the side surface of the lower end portion of the diagonal member 56 against the side surface (circumferential surface) of the upper support member 33, it becomes possible to position the lower end portion of the diagonal member 56. The lower end portion of the diagonal member 56 is directly butted against (contacted with) the upper plate 32 of the upper adjusting member 3, or is joined to the upper plate 32 in a state where a lower joining plate (plate) 56b joined to the lower end portion by welding or the like as shown in FIG. 10 is butted against the upper plate 32.

[0033] At this time, by setting so that the positioning of the lower end portion of the diagonal member 56 is achieved when the side surface of the lower end portion or the side surface of the lower joining plate 56b contacts the side surface (circumferential surface) of the upper support member 33 of the upper adjusting member 3 while the lower end portion of the diagonal member 56 remains in contact with the upper plate 32, the positioning operation of the lower end portion of the diagonal member 56 becomes easy, and thus the workability at the site is improved.

[0034] When a support member 4 that is directly installed and fixed on the ground surface 7 is arranged under the lower plate 21 of the lower adjusting member 2 as shown in FIG. 1-(a), the lower plate 21 of the lower adjusting member 2 is connected to and supported by this support member 4 (Claim 4). In this case, since the support member 4 is arranged under the lower plate 21 of the lower adjusting member 2, it is not necessary for the lower plate 21 to be directly fixed to the ground, and thus the lower plate 21 does not need to have a structure for fixing the heads of fixing tools such as anchors for fixing to the ground.

[0035] Therefore, when the lower adjusting member 2 and the upper adjusting member 3 are combined with each other, it is only necessary for the upper adjusting member 3 to perform the function of adjusting the angle of the load 6 to be supported. Since the functions of the lower adjusting member 2 and the support member 4 are separated, the structures of the lower adjusting member 2 and the support member 3 are simplified.

Advantages of the Invention

[0036] The lower plate of the upper adjusting member, which is a component of the support device, is overlapped and connected to the upper plate of the lower adjusting member, which is also a component, with the axial direction of each adjusting member facing in an arbitrary direction, so that the angle formed between the axial direction of the lower adjusting member and the axial direction of the upper adjusting member can be freely set. As a result, the angle formed between the lower plate of the lower adjusting member installed along the ground surface and the upper plate of the upper adjusting member supporting the load can be freely adjusted.

[0037] In addition, when adjusting the angle of the receiving member that directly supports the load with respect to the supporting member fixed to the ground, processing such as hole formation in the receiving member and the supporting member becomes unnecessary, and the angle adjustment work while the gantry is being supported also becomes unnecessary, so the work efficiency is improved.

Embodiments for Carrying Out the Invention

[0039] Figs. 1 to 3 show a manufacturing example of a support device 1 including a lower adjusting member 2 that is installed directly or indirectly on the ground surface 7 and fixed to the ground, and an upper adjusting member 3 that is directly or indirectly butted and connected to the lower adjusting member 2 to support an upper load 6 such as a solar cell array.

[0040] As shown in Fig. 4, the lower adjusting member 2 includes a lower plate 21 that is directly or indirectly fixed to the ground, an upper plate 22 that is spaced apart from the lower plate 21 and is supported by the lower plate 21 in a state of forming an inclined surface with respect to the lower plate 21, and a lower support member 23 that is joined to the lower plate 21 and the upper plate 22 and supports the upper plate 22 on the lower plate 21.

[0041] The form of the lower support member 23 and the method of joining the lower plate 21 and the upper plate 22 to the lower support member 23 are arbitrary. However, in Fig. 4, a steel pipe is used for the lower support member 23 that bears the vertical load of the upper load 6. In this example, as the upper plate 22 is joined to the lower plate 31 of the upper adjusting member 3, corresponding to the use of a disc-shaped plate (plate) for the upper plate 22, the upper end surface of the lower support member 23 is cut parallel to the upper plate 22 according to the angle formed by the lower plate 21 and the upper plate 22 so that the lower surface of the upper plate 22 is in surface contact.

[0042] The lower plate 21 and the upper plate 22 are joined to the lower end surface and the upper end surface of the lower support member 23 by welding or the like, respectively. In this example, for the lower plate 21 that is joined to the support member 4 described later and is directly installed on the ground surface 7, an annular plate (plate) that is less likely to interfere with the support member 4 is used for joining with the support member 4.

[0043] For the lower support member 23, other steel materials such as H-shaped steel can be used instead of the steel pipe. However, in any case, the direction of the axis (axial direction) passing through the center of the steel pipe or the like is the axial direction of the lower support member 23. Between the lower plate 21 and the upper plate 22, auxiliary stiffening members 24 for restraining the bending deformation of both are arranged at intervals in the circumferential direction of the lower support member 23 as shown in Fig. 4-(b) and are joined to both by welding or the like.

[0044] When the support member 4 is arranged under the lower adjusting member 2 and the lower plate 21 is bolted to the support member 4, insertion holes 21a through which bolts for joining with the support member 4 are inserted are formed in the lower plate 21 as shown in Fig. 4-(d). When the lower plate 31 of the upper adjusting member 3 is bolted to the upper plate 22, insertion holes 22a through which bolts for joining with the lower plate 31 are inserted are formed in the upper plate 22 as shown in Fig. 4-(c).

[0045] Here, in order to increase the degree of freedom of the angle formed between the axial direction of the lower support member 23 of the lower adjustment member 2 and the axial direction of the upper support member 33 of the upper adjustment member 3, a plurality of insertion holes 22a in the upper plate 22 shown in FIG. 4-(c) and insertion holes 31a in the lower plate 31 shown in FIG. 5-(d) joined thereto are formed at intervals in the circumferential direction. The insertion holes 22a are partially formed at regular intervals in the circumferential direction and are also formed in a long hole shape in the circumferential direction. In the case of the long hole shape, they are formed intermittently in the circumferential direction.

[0046] Also, as shown in FIG. 6, if a plurality of rows in which the insertion holes 22a and 31a are arranged at intervals in the circumferential direction are arranged in the radial direction (radius direction) of the upper plate 22 and the lower plate 31, and the insertion holes 22a and 31a are formed in a staggered pattern along the circumferential direction, it becomes possible to continuously adjust the angles α and β in the same manner as in the case of the long hole shape while sufficiently maintaining the interval between adjacent insertion holes 22a, 22a (31a, 31a). In particular, if the insertion holes 22a and 31a are formed in a long hole shape that is long in the circumferential direction, the position of the bolt can be continuously changed in the circumferential direction, enabling more detailed angle adjustment.

[0047] "Maintaining the interval between adjacent insertion holes 22a, 22a (31a, 31a)" means that the interval between the insertion holes 22a, 22a (31a, 31a) can be prevented from becoming smaller, so it can be said that the safety against breakage of the upper plate 22 and the lower plate 31 is ensured. "Continuous angle adjustment" means that, as shown in FIG. 4-(c) and FIG. 5-(d), the angles α and β are not changed discontinuously in units of several degrees but are continuously changed, unlike the case where the insertion holes 22a and 31a are arranged at intervals in a row in the circumferential direction.

[0048] As shown in FIG. 5, the upper adjustment member 3 has a lower plate 31 that faces the upper plate 22 of the lower adjustment member 2 and is connected (joined) to the upper plate 22, an upper plate 32 that is supported by the lower plate 31 in a state of forming an inclined surface with respect to the lower plate 31, and an upper support member 33 that is joined to the lower plate 31 and the upper plate 32 and supports the upper plate 32 on the lower plate 31.

[0049] In Fig. 5, a plate (disc) having the same shape as the upper plate 22 is used for the lower plate 31 joined to the upper plate 22 of the lower adjusting member 2 so as to overlap the upper plate 22. For the upper plate 32 that receives the diagonal member 56 described later, an annular plate (disc) is used in relation to the inner peripheral surface thereof being abutted against and joined (welded) to the peripheral surface of the upper support member 33.

[0050] The form of the upper support member 33 and the joining method of the lower plate 31 and the upper plate 32 to the upper support member 33 are arbitrary, but in Fig. 5 as well, a steel pipe is used for the upper support member 33 that bears the vertical load of the upper load 6. Also in this case, according to the angle formed by the lower plate 31 and the upper plate 32, the lower end surface of the upper support member 33 is cut parallel to the lower plate 31 so that the upper surface of the disc-shaped lower plate 31 is in surface contact, and the lower plate 31 is joined to the lower end surface etc. of the upper support member 33 by welding or the like. The upper plate 32 is joined to the peripheral surface closer to the upper side of the upper support member 33 by welding or the like as described above, but it may also be joined to the upper end surface of the upper support member 33.

[0051] Steel materials other than steel pipes can also be used for the upper support member 33, and the direction of the axis (axial direction) passing through the center of the steel pipe etc. becomes the axial direction of the upper support member 33. Between the lower plate 31 and the upper plate 32, stiffening members 34 for restraining the bending deformation of both are arranged at intervals in the circumferential direction of the upper support member 33 as shown in Fig. 5-(c), and are joined to both by welding or the like.

[0052] The lower plate 31 is formed with insertion holes 31a for joining to the upper plate 22 with bolts corresponding to the formation of the insertion holes 22a in the upper plate 22 of the lower adjusting member 2. Similar to the insertion holes 22a, the insertion holes 31a are partially formed at positions corresponding to the insertion holes 22a with a certain interval in the circumferential direction as shown in Fig. 5-(d), or are formed in a long hole shape.

[0053] When the lower adjusting member 2 is directly fixed to the ground, the lower plate 21 is directly placed on the ground surface 7, and a fixing portion for fixing to the ground is connected or formed. In the drawing, a dedicated support member 4 for fixing to the ground is joined below the lower plate 21.

[0054] As shown in FIG. 7 for example, the support member 4 has an arm portion 41 that radially projects outward from the position of the outer peripheral surface of the lower adjusting member 2, and a connecting portion 42 that is installed between the tip portions on the outer peripheral side of adjacent arm portions 41, 41 and connects the arm portions 41, 41 to each other. The support member 4 passes through an insertion hole 42a formed in at least one of the arm portion 41 and the connecting portion 42, and is fixed to the ground by a fixing member such as an anchor or an anchor bolt buried in the ground.

[0055] As shown in FIG. 7-(a), the lower adjusting member 2 is joined to the central portion of the arm portion 41 of the support member 4 by bolts or the like that pass through the insertion holes 21a shown in FIGS. 4-(b) and (d) formed in the lower plate 21, and is supported by the support member 4. FIGS. 8-(a) and (b) show a state in which the upper adjusting member 3 is placed on the lower adjusting member 2 shown in FIG. 7 joined to the support member 4, and the lower plate 31 of the upper adjusting member 3 is joined to the upper plate 22 of the lower adjusting member 2 in a state where the axial directions of the lower adjusting member 2 and the upper adjusting member 3 are aligned.

[0056] FIG. 8 shows a state in which the lower plate 21 of the lower adjusting member 2 is joined to the support member 4, and when the ground surface 7 is inclined with respect to the horizontal plane as shown in FIG. 1-(a), the upper load 6 is made parallel to the ground surface 7 as a whole, and the upper adjusting member 3 is combined with the lower adjusting member 2, and the lower plate 31 is joined to the upper plate 22. Or when the ground surface 7 forms a horizontal plane, it shows a state in which the upper adjusting member 3 is combined with the lower adjusting member 2 so that the upper load 6 becomes a horizontal plane as a whole, and the lower plate 31 is joined to the upper plate 22.

[0057] FIGS. 8-(b), 9-(a), and (b) show a state in which the lower adjusting member 2 is joined to the support member 4 in the state shown in FIG. 7-(b), and the upper adjusting member 3 is combined with the lower adjusting member 2 by adjusting the axial direction of the upper adjusting member 3. FIG. 8-(b) shows a case where the axial direction of the upper adjusting member 3 coincides with the axial direction of the lower adjusting member 2, and FIGS. 9-(a) and (b) show a case where the axial direction of the upper adjusting member 3 and the axial direction of the lower adjusting member 2 form an angle.

[0058] Figs. 9-(a) and (b) also show an example of the case where, as shown in Fig. 1-(a), when the ground surface 7 is inclined with respect to the horizontal plane, when viewed in a cross-section orthogonal to the inclination direction of the ground surface 7, on the upstream side (the higher side), the in-plane direction of the support member 4 (the lower plate 21) and the upper plate 22 of the lower adjusting member 2 form an angle, and the lower adjusting member 2 is joined to the support member 4. Then, an example is shown of the case where the lower plate 31 of the upper adjusting member 3 is joined to the upper plate 22 of the lower adjusting member 2 so that the upper plate 32 of the upper adjusting member 3 forms an angle α with the ground surface 7 (the lower plate 21) on the upstream side.

[0059] Fig. 9-(a) shows an example where the angle α formed by the upper plate 32 of the upper adjusting member 3 and the lower plate 21 of the lower adjusting member 2 is 10°, but there is also the case where the upper plate 32 and the upper plate 22 (the lower plate 31) are parallel. Fig. 8-(b) shows an example of the case where the upper plate 32 of the upper adjusting member 3 forms an angle with the upper plate 22 (the lower plate 31) of the lower adjusting member 2 on the downstream side (the lower side) of the ground surface 7, but shows the case where the upper plate 32 of the upper adjusting member 3 is parallel to the lower plate 21 of the lower adjusting member 2 (α = 0°).

[0060] Fig. 9-(b) shows a part of the support device 1 shown in Fig. 1-(a), and is an example of the case where the upper plate 32 of the upper adjusting member 3 forms an angle with respect to the lower plate 31 on the upstream side of the ground surface 7, and shows an example where the angle α formed by the upper plate 32 of the upper adjusting member 3 and the lower plate 21 of the lower adjusting member 2 is 20°.

[0061] As shown in Fig. 1-(a), when the ground surface 7 forms an angle θ with respect to the horizontal plane, when α = θ, the upper surface of the load 6 becomes horizontal. As shown in Figs. 8-(b) and 9-(c), when α = 0°, the upper surface of the load 6 is parallel to the ground surface 7.

[0062] Figure 9-(c) shows the case where α = 0°, similar to the example of Figure 8-(b). However, in Figure 8-(b), the upper plate 32 and the upper plate 22 (lower plate 31) form an angle on the downstream side of the ground surface 7, while Figure 9-(c) shows an example where the upper plate 32 and the upper plate 22 (lower plate 31) form an angle on the upstream side of the ground surface 7. In this case, the upper plate 22 of the lower adjustment member 2 and the lower plate 31 of the upper adjustment member 3 are inclined so that the distance from the upstream side to the downstream side of the ground increases with respect to the support member 4.

[0063] Figures 9-(c) to (e) show the case where the axial direction of the lower adjustment member 2 is adjusted so that the upper plate 22 of the lower adjustment member 2 is inclined in the same direction as the inclined ground surface 7 and the support member 4, and the upper plate 22 is joined to the support member 4. These are cases where the upper plate 22 of the lower adjustment member 2 forms an angle with the lower plate 21 (support member 4) on the downstream side of the ground surface 7, but the upper plate 22 is in an inclined state such that the distance from the upstream side to the downstream side of the ground surface 7 decreases with respect to the support member 4.

[0064] The degree of freedom in adjusting the angle α can be changed by the number of circumferential arrangements of the insertion holes 22a of the upper plate 22 shown in Figure 4-(c) and the insertion holes 31a of the lower plate 31 shown in Figure 5-(d), or by setting the length in the case of a long hole shape. The more the number of arrangements or the greater the length, the greater the degree of freedom, and detailed adjustment of the angle α becomes possible.

[0065] Figures 9-(c) to (e) show, contrary to (a) and (b), an example where the axial direction of the lower adjustment member 2 is adjusted so that the in-plane direction of the support member 4 (lower plate 21) and the upper plate 22 of the lower adjustment member 2 form an angle on the downstream side (lower side) when viewed in a cross-section perpendicular to the inclined direction of the ground surface 7, and the lower adjustment member 2 is joined to the support member 4.

[0066] Figs. 9-(c) to (e) also show the case where the axial direction of the upper adjusting member 3 is adjusted so that the upper plate 32 of the upper adjusting member 3 forms an angle β on the downstream side with respect to the ground surface 7 (lower plate 21). (c) shows the case where β = 0°, and the upper surface of the load 6 is parallel to the ground surface 7. (d) and (e) show the cases where β = 10° and β = 20° respectively. In these cases, the upper surface of the load 6 will be greatly inclined with respect to the horizontal plane compared to the ground surface 7.

[0067] Figs. 1 to 3 show a configuration example of the gantry 5 in the case where the support device 1 includes a gantry 5 that directly supports the load 6, and a diagonal member 56 that is connected (joined) to and supported by the upper plate 32 of the upper adjusting member 3 is connected to the lower surface side of the gantry 5. The configuration of the gantry 5 is arbitrary, but in this example, as shown in Figs. 1-(a) and (b), the gantry 5 is arranged substantially parallel to the ground surface 7, and a plurality of upper frame members 51 that support the load 6, and below the upper frame members 51, a plurality of upper connecting members 52 that are arranged in a direction intersecting orthogonally or otherwise with the upper frame members 51 and support the plurality of upper frame members 51 are used as the basic upper framework 5A.

[0068] In particular, in Figs. 1 to 3, in order to make it easier to support the upper framework 5A of the gantry 5 by the upper adjusting member 3, as shown in Figs. 1-(a) and 2-(a), below the upper connecting members 52, a plurality of lower frame members 53 that are arranged substantially parallel to the ground surface 7 and receive the upper connecting members 52, and a lower connecting member 54 that is installed between adjacent lower frame members 53 and 53 are arranged to form a lower framework 5B, and the upper framework 5A is joined to the lower framework 5B. Fig. 1-(b) shows the state where the lower framework 5B is arranged below the upper framework 5A.

[0069] Here, as shown in Figs. 1-(b) and 2-(a), in order to ensure the in-plane rigidity of the lower framework 5B, a welding rod 55 that intersects both is installed between the lower frame member 53 and the lower connecting member 54. In particular, in order to suppress the thickness of the lower framework 5B, the lower connecting member 54 is arranged within the height range of the lower frame member 53, and the welding rod 55 is arranged within the height range of the lower frame member 53 and the lower connecting member 54. In this example, there is no step between the lower frame member 53 and the lower connecting member 54, and the welding rod 55 is arranged within a certain thickness range including both of them.

[0070] Below the lower framework 5B, as shown in Fig. 1-(a) and Fig. 2-(b), a diagonal member 56 is installed to connect the lower framework 5B and the upper plate 32 of the upper adjusting member 3, and to transfer the load of the upper load 6 to the upper adjusting member 3. The diagonal member 56 is installed, for example, between the lower surface of the lower framework 5B and the upper surface of the upper plate 32 of the upper adjusting member 3 and is joined to both. In the example shown in Fig. 1, as shown in Fig. 2-(b), the diagonal member 56 is installed between the diagonal direction on the plane of the lower framework 5B and one of the lower frame members 53 from the upper plate 32.

[0071] In order to facilitate joining the diagonal member 56 to the lower surface of the lower framework 5B and the upper surface of the upper plate 32, in the example shown in the figure, the axial end faces of the diagonal member 56 are cut so as to form a plane parallel to the lower surface of the lower framework 5B and the upper surface of the upper plate 32 as shown in Fig. 10-(a), and an upper joining plate 56a and a lower joining plate 56b for joining are integrated by welding or the like to each end face as shown in (b). The diagonal member 56 shown in Fig. 10 shows the diagonal member 56 appearing in Fig. 1-(a).

[0072] The "lower surface of the lower framework 5B" is the lower surface of at least one of the lower frame member 53 and the lower connecting member 54. When joining the upper end face of the diagonal member 56 to the lower surface of the lower framework 5B, the length of the diagonal member 56 changes according to, for example, the inclination angle θ between the horizontal plane when the upper surface of the upper load 6 is horizontal and the ground surface 7, and the cutting angles of both axial end faces may also change. However, if the upper joining plate 56a and the lower joining plate 56b are rotatably connected to both ends of the diagonal member 56 in an arbitrary direction, the follow-up ability to the change in the inclination angle θ is enhanced.

[0073] The upper joint plate 56a of the diagonal member 56 is joined by bolts or the like in a state of abutting against the lower surface of the lower framework 5B, and the lower joint plate 56b is joined by bolts or the like in a state of abutting against the upper surface of the upper plate 32 of the upper adjusting member 3. Here, as shown in FIGS. 1-(a) and 3, if the upper plate 32 of the upper adjusting member 3 is joined to the upper support member 33 at a position below the upper end surface of the upper support member 33, by abutting the side surface (circumferential surface) of the lower joint plate 56b against the side surface (circumferential surface) of the upper support member 33, the lower joint plate 56b can be positioned in a state of abutting against the upper surface of the upper plate 32, and the working efficiency at the time of joining to the upper plate 32 is improved.

[0074] As shown in FIG. 2-(b), when a plurality of diagonal members 56 are arranged radially with respect to the center of the upper support member 33 of the upper adjusting member 3 on a plane, the adjacent lower joint plates 56b, 56b of the plurality of diagonal members 56 can come into contact with each other in the circumferential direction of the upper support member 33 on the upper surface of the upper plate 32. Therefore, the lower joint plates 56b of the plurality of diagonal members 56 are easily positioned in the circumferential direction.

[0075] In addition, since the side surface on the upper support member 33 side of each lower joint plate 56b comes into contact with the circumferential surface (surface) of the upper support member 33, the positioning of each lower joint plate 56b of the diagonal member 56 in the axial direction of the diagonal member 56 is achieved, so that the lower joint plate 56b can be accurately joined to the upper plate 32 of the upper adjusting member.
