Abstract
Description
Fixing jig for towing work machine and method of moving cargo using the same
[0001] The present invention relates to a fixing jig for a towing work machine and a method for moving loads using the same, and more particularly to a fixing jig for a towing work machine used to move loads such as transported objects (e.g., heavy objects such as transformers) that have been unloaded and placed on a foundation to a predetermined installation position on the foundation while towing them laterally, and to a method for moving loads using the same.
[0002] Conventionally, when an object (heavy object) that has been unloaded and placed on a foundation is moved and positioned to a predetermined installation position on the foundation, the following method has been used: A towing machine (winch) is fixed to the foundation by a fixing member such as an anchor member or bracket, and one end (free end) of a traction wire extending from the towing machine (winch) is tied to the object (heavy object), and the towing machine (winch) is operated to wind up the towing wire, thereby moving the object (heavy object) toward the predetermined installation position on the foundation (toward the towing machine (winch)) (see, for example, Patent Document 1, etc.).
[0003] Patent Document 1 discloses an example in which a fixing member (anchor member) for fixing a towing work machine (winch) is embedded in a foundation floor surface. Specifically, as shown in FIG. 4 of Patent Document 1, a hook member (3) of an embedded hook (F) having an anchor member (1) embedded and fixed in a foundation (floor slab (S)) is connected to a winch (towing work machine (D)) via a cable (11), and the free end of a towing cable (14) paid out from the winch is fastened to the front end of the transported object (facility machine (M)). The winch is then operated to reel in and drive the towing cable (14), thereby towing and transporting the transported object (facility machine (M)) to a predetermined installation position on the foundation (floor slab (S)) (see paragraph
[0019] of Patent Document 1).
[0004] Furthermore, Patent Document 2 discloses an example in which stays (29) are fixed to a vibration test stand (5) (corresponding to a foundation) at positions corresponding to the four corners of a transported object (a reinforced concrete structure (2)) placed on the vibration test stand (5), and four lateral pushing jacks (30) fixed to the stays (29) are used (see paragraph
[0032] , Figures 5 and 7 of Patent Document 2). In this case, as shown in Figure 5 of Patent Document 2, two jacks (30) are provided for each of the opposing faces of the transported object (the reinforced concrete structure (2)), which is rectangular in plan view. Furthermore, the two jacks (30) corresponding to each face of the transported object are arranged at a certain distance. Then, by adjusting the relative extension and contraction of each jack (30), the transported object (the reinforced concrete structure (2)) is moved back and forth and left and right or rotated in a horizontal plane, and the transported object is positioned at a predetermined position on the foundation (vibration test stand (5)).
[0005] JP 2000-008621 A JP 2000-110358 A
[0006] As described above, in the prior art, fixing members (brackets, etc.) for supporting (fixing) winches and jacks for moving transported objects (heavy objects) on a foundation at predetermined positions are often embedded and fixed in the foundation. In Patent Document 1, the fixing members are anchor members, which are embedded and fixed in the foundation. In Patent Document 2, stays (fixing members) for fixing the jacks are fixed to the foundation by fixing devices such as anchor bolts driven into the foundation. As such, the above-mentioned fixing members are often fixed by driving the fixing devices into the foundation themselves, which increases the risk of damaging or breaking the foundation. Therefore, after the transported object (heavy object) has been placed and positioned on the foundation and the winch and fixing members (brackets, etc.) have been removed, the foundation needs to be repaired as appropriate.
[0007] Furthermore, if a pit is provided in the foundation, a fixing member, such as a timber (wood) driven into the pit, is provided, and the winch is held in place via a metal wire, etc. However, even in this case, there is a possibility that the foundation may be damaged or broken when the timber is removed.
[0008] The present invention has been made in consideration of the above circumstances, and aims to provide a fixing jig for a towing work machine that can be placed and fixed to a foundation without damaging or breaking the foundation, and a method for moving cargo such as transported items (e.g., heavy objects such as transformers) using the same.
[0009] In order to achieve the above-mentioned object, the fixing jig for a towing work machine according to the present invention is configured as follows: (1) A fixing jig for a towing work machine that tows a load placed on a foundation and moves the load on the foundation, characterized by comprising: a plate-shaped base that is installed on the foundation; a wall portion that is fixed to the base and has a plane that extends in a direction approximately perpendicular to a plane that includes the installation surface of the base; a connection portion that is connected to the towing work machine and fixes the towing work machine, the connection portion being fixed to the plane that extends in the approximately perpendicular direction of the wall portion; and a fixing portion that comes into contact with the foundation and restricts movement of the fixing jig in the towing direction of the towing work machine.
[0010] In the above configuration (1), the "installation surface of the base" refers to the surface that is installed on (comes into contact with) the upper surface of the foundation when the fixing jig is placed and fixed on the foundation.
[0011] According to the above-mentioned configuration (1) of the fixing jig for a towing work machine of the present invention, in particular, it is possible to provide a fixing jig for a towing work machine that can be positioned and fixed to the foundation without damaging or breaking the foundation, by being provided with a fixing part that comes into contact with the foundation and restricts movement of the fixing jig in the direction in which the towing work machine is towed.
[0012] In the above-mentioned configuration (1) of the fixing jig for a towing work machine of the present invention, it is preferable to have the following configurations (2) to (9).
[0013] (2) In the configuration of (1) above, the fixing portion comprises: a first leg, which is a plate-like member extending approximately vertically downward from the installation surface of the base, one surface of which is configured to contact one side of a pit provided in the foundation; and a second leg, which is a plate-like member extending approximately vertically downward from the installation surface of the base, one surface of which faces approximately parallel to the other surface of the first leg, and the other surface of which is configured to contact the other side of the pit.
[0014] According to the preferred configuration of (2) above, it is possible to restrict movement of the fixing jig in the direction of towing of the towing work machine simply by fitting the first leg and the second leg into pits provided in the foundation. Therefore, according to the preferred configuration of (2) above, it is possible to realize a fixing jig for a towing work machine with a simple and low-cost configuration that can be placed and fixed to the foundation without damaging or breaking the foundation.
[0015] (3) In the configuration of (2) above, the second leg is configured so that the distance between the other surface of the second leg and the one surface of the first leg can be adjusted.
[0016] According to the preferred configuration (3) above, the distance between one side of the first leg and the other side of the second leg can be adjusted to match the width of the pit provided in the foundation, making it possible to apply this to pits of various sizes and widths.
[0017] (4) In the configuration of (3) above, the base is provided with long holes extending in the towing direction of the towing work machine at at least two locations approximately perpendicular to the longitudinal direction of the long holes, the fixing portion further includes a positioning member extending approximately perpendicular to the longitudinal direction of the long holes and having a contact surface that contacts the upper surface of the base and is slidable in the longitudinal direction of the long holes, the positioning member is provided with first holes having central axes positioned approximately on the central axes of the long holes, and the second leg is provided with second holes having central axes positioned approximately on the central axes of the long holes, and with the first hole, long hole, and second hole portions aligned, a positioning bolt is inserted into the first hole, long hole, and second hole portions, and a positioning nut is threadedly fitted onto the tip of the positioning bolt, thereby connecting and holding the second leg and the positioning member together via the base.
[0018] The preferred configuration (4) above provides the following advantageous effects. By loosening the positioning nuts threadedly fitted onto the tip ends of the positioning bolts slightly while maintaining the second leg and the positioning member held together via the base, the second leg and the positioning member can be slid integrally along the longitudinal direction of the elongated hole between one end and the other end of the elongated hole. After sliding the second leg and the positioning member to the desired position, the positioning nuts can be threadedly fitted onto the tip ends of the positioning bolts, thereby positioning and fixing the second leg at the desired position. Here, the desired position refers to the position of the second leg and the positioning member that allows the first leg and the second leg to be fitted into a pit formed in the foundation.
[0019] (5) In the configuration of (4) above, the positioning member is provided with a standing portion having a surface approximately perpendicular to the contact surface, and third hole portions are drilled in the standing portion at at least two locations approximately perpendicular to the longitudinal direction of the long hole portion, and the fixing portion further includes a positioning member fixing mechanism for fixing the position of the positioning member, and the positioning member fixing mechanism has: one end fixed to the plane to which the connection portion of the wall portion is fixed, passing through the third hole portion drilled in the standing portion of the positioning member and extending in the longitudinal direction of the long hole portion; and two positioning member fixing nuts that are threadedly fitted into the positioning member fixing long thread portions and are arranged to sandwich the standing portion from both sides of the standing portion of the positioning member.
[0020] According to the preferable configuration of (5) above, it is possible to reliably position and fix the second leg portion and the positioning member at the desired position.
[0021] (6) In the configuration of (5) above, the positioning member fixing mechanism further includes a long screw portion support member that is provided at or near the end opposite the connection portion of the base and supports the other end of the long screw portion for fixing the positioning member.
[0022] According to the preferred configuration of (6) above, the long threaded portion for fixing the positioning member can be reliably made to extend in the longitudinal direction of the elongated hole and in the direction of the central axis of the third hole, thereby enabling the second leg and the positioning member to slide smoothly in the longitudinal direction of the elongated hole as a unit.
[0023] (7) In the configuration of (1) above, the plane of the wall portion extending in a direction approximately perpendicular to the plane including the installation surface of the base extends to both the upper surface side and the installation surface side of the base, the fixing portion consists of the installation surface of the base and the plane of the wall portion extending toward the installation surface side of the base, and the installation surface of the base and the plane of the wall portion extending toward the installation surface side of the base form approximately a right angle with each other so that the fixing portion contacts both the upper surface and the front end surface of the foundation, which form the corner of the foundation.
[0024] According to the preferred configuration of (7) above, it is possible to restrict movement of the fixing jig in the direction of towing of the towing work machine simply by bringing the installation surface of the base and the flat surface of the wall portion extending toward the installation surface of the base into contact with both the top surface of the base and the front end surface of the base, which form the corners of the base. Therefore, according to the preferred configuration of (7) above, it is possible to realize a fixing jig for a towing work machine with a simple and low-cost configuration that can be placed and fixed to the foundation without damaging or breaking the foundation.
[0025] (8) In the configuration of (7) above, a part of the plane of the wall portion extending toward the installation surface of the base is provided with an extended wall portion extending in a direction approximately perpendicular to the direction in which the base extends toward the installation surface.
[0026] According to the preferred configuration of (8) above, the area (contact area) of the portion of the fixing part (wall part (fixing wall part)) that contacts the front end face of the foundation can be increased, so the wall part (fixing wall part) can be firmly held to the front end face of the foundation. As a result, it is possible to minimize the risk of the fixing jig coming off the corner of the foundation during the towing operation.
[0027] (9) In the configuration of (7) above, a plate-shaped upper support plate is provided on the upper surface side of the base, spaced apart from the base and approximately parallel to it, and fixed approximately perpendicularly to the plane of the wall portion, and the connection portion is also fixed to the upper surface of the base and the lower surface of the upper support plate.
[0028] According to the preferable configuration of (9) above, the connection portion is made strong, and it is possible to realize a fixing jig that can sufficiently withstand the pulling of a heavy object such as a transformer.

[0046] The present invention will be described in more detail below using preferred embodiments, but the following embodiments are merely examples of realizing the present invention and the present invention is not limited thereto.
[0047] [Embodiment 1] (Configuration of Fixing Jig) First, the configuration of a fixing jig for a towing work machine (hereinafter simply referred to as "fixing jig") in this embodiment will be described with reference to Figs. 1 to 3.
[0048] FIG. 1 is an explanatory diagram showing an example of use of a fixing jig in this embodiment ((a) is a side view, and (b) is a plan view), FIG. 2 is a plan view showing a specific configuration of the fixing jig, and FIG. 3 is a cross-sectional view taken along line III-III in FIG. 2.
[0049] As shown in FIG. 1 , the fixing jig 1 of this embodiment is a jig used to fix a traction implement 4 that pulls a load 3 placed on a foundation 2 to move the load 3 on the foundation 2. One end (free end) of a traction wire 23 extending from the traction implement 4 is fastened to the load 3. The other end of the traction implement 4 is connected to the fixing jig 1 via a platform wire (fixing implement) 25. The traction implement 4 is operated to wind up the traction wire 23, thereby pulling the load 3 and moving the load 3 toward a predetermined installation position on the foundation 2 (in the direction of arrow P). In FIG. 1 , R indicates an "installation reference point" that serves as a reference for the installation position where the load 3 is to be installed. When the front end face of the load 3 in the movement direction (direction of arrow P) reaches the installation reference point R, the traction implement 4 terminates the operation of winding up the traction wire 23.
[0050] The foundation 2 is made of concrete or the like. The cargo 3 is an object to be transported (for example, a heavy object such as a transformer). A winch, for example, can be used as the traction implement 4. In this embodiment, an electric winch is used as the traction implement 4. Note that in FIG. 1 , a "heavy object transport cart (transport vehicle)" used in "Method 1 for moving cargo" described later is omitted.
[0051] As shown in Figures 1 to 3, the basic configuration of the fixing jig 1 includes a rectangular plate-shaped base 5 placed on a foundation 2, a wall portion 6 that is fixed to the base 5 and has a flat surface that extends in a direction approximately perpendicular to a plane that includes the installation surface of the base 5, a connection portion 7 that is connected to the towing work machine 4 and fixes the towing work machine 4 and is fixed to the flat surface of the wall portion 6 that extends in the approximately perpendicular direction, and a fixing portion 8 (see Figure 1(a)) that comes into contact with the foundation 2 and restricts movement of the fixing jig 1 in the towing direction of the towing work machine 4 (the direction opposite to the direction of arrow P in Figure 1).
[0052] Here, the "installation surface of the base 5" refers to the surface that is installed (abuts) on the upper surface of the base 2 when the fixing jig 1 is placed and fixed on the base 2. The wall portion 6 is provided standing approximately vertically on the upper surface side of the base 5. The connection portion 7 is provided on the side of the wall portion 6 that faces the load 3, and is connected to the towing work machine 4 via a platform attachment wire 25 (fixing device). The connection portion 7 has a connection hole 7a drilled therein for connection to the platform attachment wire 25 (fixing device).
[0053] According to the configuration of the fixing jig 1 of this embodiment, in particular, by being provided with a fixing portion 8 that comes into contact with the foundation 2 and restricts the movement of the fixing jig 1 in the direction of towing by the towing work machine 4, it is possible to provide a fixing jig 1 that can be positioned and fixed to the foundation 2 without damaging or breaking the foundation 2.
[0054] 1 to 3, the fixing part 8 comprises a first leg 10, which is a rectangular plate-like member extending substantially vertically downward from the installation surface of the base 5, one surface of which is configured to contact one side of a pit 9 provided in the foundation 2, and a second leg 11, which is a rectangular plate-like member extending substantially vertically downward from the installation surface of the base 5, one surface of which faces substantially parallel to the other surface of the first leg 10 and the other surface of which is configured to contact the other side of the pit 9. Here, the pit 9 is for burying wiring or the like in the ground, and is, for example, a trench with a rectangular cross section or a U-shaped cross section.
[0055] The first leg 10 and the second leg 11 (two fixing legs) are arranged opposite each other at a predetermined distance in the width direction of the pit 9. As shown in Fig. 1, the distance Wb between one surface of the first leg 10 and the other surface of the second leg 11 is approximately equal to the width WP of the pit 9, that is, Wb≦WP. Therefore, the first leg 10 and the second leg 11 (two fixing legs) fixed to the base 5 can be inserted (fitted) into the pit 9.
[0056] When the first leg 10 and the second leg 11 (two fixing legs) are inserted (fitted) into the pit 9, one opposing side of the rectangular plate-shaped base 5 is approximately parallel to both widthwise edges of the pit 9, and the other opposing side of the rectangular plate-shaped base 5 is approximately perpendicular to both widthwise edges of the pit 9. As shown in FIGS. 1 to 3 , support portions 5a and 5b are provided on each opposing side of the rectangular plate-shaped base 5. The distance between both ends of the support portions 5a and 5b in the X-axis direction is WB, and WB > WP (WP is the width of the pit 9), so that when the first leg 10 and the second leg 11 (two fixing legs) are inserted (fitted) into the pit 9, the base 5 can be installed and fixed in a predetermined position on the upper surface of the foundation 2.
[0057] At least one of the support portions 5a and 5b may be formed integrally with the base 5. Alternatively, at least one of the support portions 5a and 5b may be separate from the base 5 and fixed to the base 5. FIGS. 1 to 3 illustrate a case in which the support portion 5a is separate from the base 5 and the support portion 5b is integrated with the base 5.
[0058] According to the configuration of the fixing jig 1 of this embodiment described above, it is possible to restrict movement of the fixing jig 1 in the towing direction of the towing work implement 4 (the direction opposite to the direction of arrow P in FIG. 1 ) simply by fitting the first leg 10 and the second leg 11 (two fixing legs) into the pit 9 provided in the foundation 2. Therefore, according to the configuration of the fixing jig 1 of this embodiment described above, it is possible to realize a fixing jig 1 that can be positioned and fixed to the foundation 2 without damaging or breaking the foundation 2, with a simple and low-cost configuration.
[0059] 2 and 3, the second leg 11 is configured to be adjustable in distance Wb between the other surface thereof and one surface of the first leg 10. With this configuration, the distance Wb between one surface of the first leg 10 and the other surface of the second leg 11 can be adjusted to match the width WP (see FIG. 1(b)) of the pit 9 provided in the foundation 2, making it possible to apply the device to pits 9 of various sizes and different widths.
[0060] 2 and 3, one end face (parallel to the Y-Z plane) of the base 5, which is made of a rectangular steel plate, is welded to the surface (parallel to the Y-Z plane) of the wall 6, which is also made of a rectangular steel plate, so that the wall 6 extending in the Z-axis direction and the base 5 extending in the X-axis direction are approximately perpendicular to each other. The welded surface is located at a predetermined position on the surface of the wall 6, spaced from the end of the wall 6, so that the distance from either the upper or lower end (the upper end in FIG. 3) of the wall 6 to the installation surface (lower surface) of the base 5 is a predetermined distance (L0). As shown in FIG. 3, the portion of the wall 6 that extends in the -Z-axis direction from the installation surface (lower surface) of the base 5, which is welded as described above, becomes the first leg 10 (fixing leg).
[0061] 2 and 3 , one side of each of the gripping portions 22a and 22b, each made of a right-angled triangular steel plate, is welded to both ends of the wall portion 6 in the Y-axis direction, including the surface of the wall portion 6 that is welded to the base 5. The other side of each of the gripping portions 22a and 22b, each made of a right-angled triangular steel plate, is welded to both ends of the top surface of the base 5 in the Y-axis direction. That is, the wall portion 6 and the base 5 are welded to the pair of gripping portions 22a and 22b, with the right-angled portions of the gripping portions 22a and 22b sandwiched between them. Each of the two gripping portions 22a and 22b has a gripping hole 22c formed therein. This allows an operator to grip the gripping hole 22c to transport the fixing jig 1.
[0062] As shown in FIGS. 1 to 3 , a connection portion 7 that is connected to the traction implement 4 via a platform mounting wire (fixing device) 25 is provided on a surface of the wall portion 6 that includes the welding surface with the base 5. The connection portion 7 is made of a plate-shaped steel material. A connection hole 7a is drilled in the connection portion 7 for connection to the platform mounting wire (fixing device) 25. The plate-shaped connection portion 7 has at least one side that forms a right angle, and one side of the right-angled side is welded to the surface of the wall portion 6 that includes the welding surface with the base 5, and the other side of the right-angled side is welded to the upper surface (top surface) of the base 5. The connection hole 7a is drilled as a through-hole in a surface of the connection portion 7 that is parallel to the X-Z plane.
[0063] A support part 5a made of an equal-legged angle iron (equal-legged angle) is welded to the surface of the wall part 6 opposite to the surface including the welding surface with the base 5. The welding surface of the support part 5a is a surface parallel to the Y-Z plane of the equal-legged angle, and the surface parallel to the X-Y plane of the equal-legged angle is disposed on approximately the same plane as the installation surface (lower surface) of the base 5. In addition, the part of the base 5 that extends further in the X-axis direction than the movable die fixing legs described below constitutes the support part 5b.
[0064] As described above, the distance Wb between the two fixing legs (the distance between one surface of the first leg 10 and the other surface of the second leg 11) is approximately equal to the width WP of the pit 9, with Wb≦WP. The width WP of the pit 9 varies depending on the conditions of the foundation 2 and the load (heavy load) 3, so as described above, it is preferable to make the distance Wb between the two fixing legs adjustable to match the width WP of the pit 9. As shown in FIG. 3 , one of the two fixing legs is a movable fixing leg configured so that the distance Wb relative to the other (first leg 10) can be adjusted.
[0065] 3, the movable die fixing leg includes a second leg (movable part) 11 and a (movable part) positioning member 13. The second leg (movable part) 11 is made of an unequal angle iron (an unequal angle). On the other hand, the positioning member 13 is made of an equal angle iron (an equal angle). Two first holes 14 are drilled on one side of the positioning member 13, spaced a predetermined distance apart (L1, as described below).
[0066] As shown in Figures 1 to 3, elongated holes 12a, 12b extending in the direction in which the towing work implement 4 is towed (the direction opposite to the direction of arrow P in Figure 1) are drilled in the base 5 at two locations on both ends that are approximately perpendicular to the longitudinal direction of the elongated holes 12a, 12b. More specifically, as shown in Figures 2 and 3, two elongated holes 12a, 12b extending in the X-axis direction are drilled at two locations on both ends of the base 5 in the Y-axis direction, inward from the two gripping portions 22a, 22b. The distance between the central axes of the elongated holes 12a, 12b is L1.
[0067] As shown in Figures 2 and 3, the positioning member 13 extends in a direction (Y-axis direction) substantially perpendicular to the longitudinal direction of the elongated holes 12a and 12b, is slidable in the longitudinal direction of the elongated holes 12a and 12b, and has a contact surface that comes into contact with the upper surface of the base 5. Two first holes 14, each having a central axis positioned substantially on the central axis of each of the elongated holes 12a and 12b, are formed on one side of the positioning member 13, which is made of an equal-leg angle iron (equal-leg angle). The distance between the central axes of the two first holes 14 is also L1. The side of the positioning member 13 on which the first holes 14 are formed is installed on the upper surface of the base 5.
[0068] Therefore, the positioning member 13 can be installed on the upper surface of the base 5 so that the central axis of one first hole 14 is aligned approximately on the central axis of one elongated hole 12a, and the central axis of the other first hole 14 is aligned approximately on the central axis of the other elongated hole 12b. As shown in Figure 2, the length of the positioning member 13 in the longitudinal direction (Y-axis direction) is approximately equal to or slightly shorter than the distance L2 between the two opposing surfaces of the two gripping portions 22a, 22b. This allows the positioning member 13 to slide in the longitudinal direction (X-axis direction) of the elongated holes 12a, 12b in the space between the two opposing surfaces of the two gripping portions 22a, 22b.
[0069] 2 and 3 , two second holes 15 are formed on the short sides of the second leg (movable part) 11, which is made of unequal angle iron (unequal angle), with central axes aligned approximately on the central axes of the respective elongated holes 12 a and 12 b. Here, the distance between the central axes of the two second holes 15 is also L1. When the surface of the short side of the second leg (movable part) 11, on which the two second holes 15 are formed, is brought into contact with the installation surface (bottom surface) of the base 5 with its longitudinal direction aligned in the Y-axis direction, the central axis of one second hole 15 can be aligned approximately on the central axis of one elongated hole 12 a, and the central axis of the other second hole 15 can be aligned approximately on the central axis of the other elongated hole 12 b.
[0070] That is, one of the first holes 14 of the positioning member 13 and one of the second holes 15 of the second leg (movable part) 11 can be arranged coaxially via one of the long holes 12a. Also, the other of the first holes 14 of the positioning member 13 and the other of the second holes 15 of the second leg (movable part) 11 can be arranged coaxially via the other of the long holes 12b. Therefore, with one first hole portion 14, one long hole portion 12a, and one second hole portion 15 of the second leg (movable part) 11 aligned, a positioning bolt 16a is inserted into the one first hole portion 14, one long hole portion 12a, and one second hole portion 15, and with the other first hole portion 14, the other long hole portion 12b, and the other second hole portion 15 of the positioning member 13 aligned, a positioning bolt 16b is inserted into the other first hole portion 14, the other long hole portion 12b, and the other second hole portion 15, and positioning nuts 17a, 17b (positioning nut 17a is not shown) are screwed and fitted into the respective tip portions of the two positioning bolts 16a, 16b, thereby connecting and holding the second leg (movable part) 11 and the positioning member 13 together via the base 5.
[0071] The above configuration provides the following advantageous effects. Specifically, by slightly loosening the positioning nuts 17a, 17b threadedly fitted onto the tip ends of the positioning bolts 16a, 16b while maintaining the second leg (movable part) 11 and the positioning member 13 held via the base 5, the second leg (movable part) 11 and the positioning member 13 can be slid integrally in the longitudinal direction (X-axis direction) of the elongated holes 12a, 12b between one end and the other end of the elongated holes 12a, 12b extending in the X-axis direction. After sliding the second leg (movable part) 11 and the positioning member 13 to a desired position, the positioning nuts 17a, 17b can be threadedly fitted onto the tip ends of the positioning bolts 16a, 16b, respectively, thereby positioning and fixing the second leg (movable part) 11 at the desired position. Here, the desired position refers to the position of the second leg (movable part) 11 and the positioning member 13 (the position where Wb ≒ WP (see Figure 1)) that allows the first leg 10 and the second leg (movable part) 11 to be fitted into the pit 9 provided in the foundation 2.
[0072] When carrying out the work of pulling a load (heavy object) 3 horizontally using the fixing jig 1 of this embodiment, the first leg 10 and the second leg 11 (two fixing legs) must be securely fixed to the pit 9. Therefore, it is desirable that the movable fixing legs (the second leg (movable part) 11 and the positioning member 13) are securely positioned and fixed in the desired position during the above work.
[0073] In order to reliably position and fix the movable mold fixing leg (the second leg (movable part) 11 and the positioning member 13) at the desired position, the fixing part 8 (see Figure 1) is equipped with a positioning member fixing mechanism having long screw parts 19a, 19b for fixing the positioning member as shown in Figures 2 and 3.
[0074] 2 and 3 , long threaded portions 19a, 19b for fixing positioning members (hereinafter simply referred to as "long threaded portions") are threadably fitted at one end to nuts 40a, 40b, which are fixed by welding or the like to the flat surface to which connection portion 7 of wall portion 6 is welded. By being threadably fitted to nuts 40a, 40b, which are fixed by welding or the like to the flat surface to which connection portion 7 of wall portion 6 is welded, long threaded portions 19a, 19b are arranged to extend in the longitudinal direction (X-axis direction) of long hole portions 12a, 12b. The other ends of long threaded portions 19a, 19b are supported by long threaded portion support members 21a, 21b, respectively, provided at the end opposite the welded portion to wall portion 6 of base 5 (the end opposite connection portion 7). That is, the long thread portion support members 21a, 21b each have a hole 31 drilled in the surface facing the wall portion 6 (a surface parallel to the Y-Z plane), and the other ends of the long thread portions 19a, 19b are inserted into and supported by the hole 31. The nuts 40a, 40b and the long thread portion support members 21a, 21b are arranged so that the axes of the long thread portions 19a, 19b are spaced apart a predetermined distance (L3) in the Y-axis direction.
[0075] In particular, since the positioning member fixing mechanism has the long thread portion support members 21a, 21b, the long thread portions 19a, 19b can be reliably made to extend in the longitudinal direction of the long hole portions 12a, 12b and in the direction of the central axis of the third hole portion 18, which will be described later. As a result, the second leg portion (movable portion) 11 and the positioning member 13 can be smoothly slid integrally in the longitudinal direction of the long hole portions 12a, 12b.
[0076] 2 and 3 , the positioning member 13, which is made of an equal-leg angle iron (equal-leg angle), has two third holes 18 drilled in the other side (the side forming a substantially right angle with the side along which the first hole 14 is drilled) standing upright from the base 5. More specifically, the positioning member 13 has an upright portion 13a having a surface that is substantially perpendicular to the contact surface that contacts the upper surface of the base 5, and the upright portion 13a has three third holes 18 drilled in two locations: one in the longitudinal direction (X-axis direction) of the long hole portions 12a, 12b and the other in a substantially perpendicular direction (Y-axis direction). The two third holes 18 are drilled at positions that allow the two long screw portions 19a, 19b to pass through, respectively.
[0077] The positioning member 13 is restricted in its movement in the Y-axis and Z-axis directions by positioning bolts 16a, 16b that pass through the first hole portion 14 and the long hole portions 12a, 12b of the base 5, respectively, and long screw portions 19a, 19b that pass through the two third hole portions 18, respectively, so that it can slide (move) only in the X-axis direction.
[0078] As shown in Figures 2 and 3, the positioning member fixing mechanism further has two positioning member fixing nuts 20a and 20b that are threadedly fitted into the long threaded portions 19a and 19b, respectively, and are arranged to sandwich the standing portion 13a of the positioning member 13 from both sides of the standing portion 13a.
[0079] According to the configuration of the positioning member fixing mechanism described above, it is possible to reliably position and fix the movable mold fixing leg (the second leg (movable part) 11 and the positioning member 13) at the desired position.
[0080] The position of the movable mold fixing legs (second leg (movable part) 11 and positioning member 13) can be adjusted as follows. First, the positioning nuts 17a, 17b threadedly fitted to the tips of the positioning bolts 16a, 16b are slightly loosened so that the second leg (movable part) 11 and positioning member 13 can be slid integrally in the longitudinal direction (X-axis direction) of the elongated hole parts 12a, 12b. Next, the tightening positions of the positioning member fixing nuts 20a, 20b are adjusted so that the other surface of the second leg (movable part) 11 facing the other side of the pit 9 comes into contact with the other side of the pit 9, and the positioning member fixing nuts 20a, 20b are then tightened. Finally, the positioning nuts 17a, 17b that were loosened are tightened.
[0081] (Luggage Moving Method 1) Next, luggage moving method 1 using the fixing jig in this embodiment will be explained with reference to Figures 4 and 5, using an example in which the luggage is a transported item (e.g., a heavy item such as a transformer).
[0082] Figure 4 is a side view illustrating the steps of preparing and positioning a heavy-duty transport cart and unloading the heavy-duty transport cart so that the heavy-duty transport cart can be loaded with the luggage (heavy object) in method 1 of moving luggage (heavy object) using a fixing jig in this embodiment. Figure 5 is a side view illustrating the steps of placing and fixing the fixing jig to the foundation to moving the luggage (heavy object) to the installation reference point on the foundation in method 1 of moving luggage using the fixing jig.
[0083] As shown in Figures 4 and 5, the method 1 for moving luggage in this embodiment is a method for moving luggage in which a fixing jig 1 shown in Figures 1 to 3 is used to pull luggage 3, such as an object to be transported (e.g., a heavy object such as a transformer) placed on a foundation 2, and move the luggage (heavy object) 3 on the foundation 2.
[0084] First, as shown in Figure 4, a heavy-duty transport vehicle (e.g., a roller for moving heavy objects) 24 is prepared and positioned at an unloading position on the foundation 2 (Step 1). Next, also as shown in Figure 4, a load (heavy object) 3 is transported to the unloading position on the foundation 2 by a trailer or the like, and the load (heavy object) 3 is unloaded onto the heavy-duty transport vehicle (hereinafter referred to as the "transport vehicle") 24 (Step 2). The load (heavy object) 3 is provided with legs 27 on its underside. As will be described later, the legs 27 are made of, for example, H-shaped steel. Specifically, the unloading in Step 2 described above is performed so that the load (heavy object) 3 is placed on the transport vehicle 24 via the legs 27.
[0085] Next, as shown in Fig. 5 , the fixing jig 1 is placed and fixed to the foundation 2 (step 3). More specifically, the first leg 10 and the second leg 11 of the fixing jig 1 are fitted into a pit 9 provided in the foundation 2 so that the plane to which the connection portion 7 of the wall portion 6 of the fixing jig 1 is welded faces the load (heavy object) 3, thereby placing and fixing the fixing jig 1 to the foundation 2. Even more specifically, as shown in Fig. 1 , after adjusting the distance Wb between one surface of the first leg 10 and the other surface of the second leg 11 of the fixing jig 1 to match the width WP of the pit 9, the first leg 10 and the second leg 11 (two fixing legs) are fitted into the pit 9 provided in the foundation 2, thereby placing and fixing the fixing jig 1 to the foundation 2.
[0086] According to this method of positioning and fixing the fixing jig 1, it is possible to position and fix the fixing jig 1 to the foundation 2 without damaging or breaking the foundation 2, so that, as will be described later, after the cargo (heavy object) 3 has been placed and positioned on the foundation 2 and the towing machine 4, etc. has been removed, there is no need to repair the foundation 2.
[0087] 5 , the towing work machine 4 is fixed to the fixing jig 1, and one end (free end) of the towing wire 23 extending from the towing work machine 4 is tied to the leg 27 of the load (heavy object) 3 (step 4). More specifically, the towing work machine 4 is fixed to the fixing jig 1 via a platform attachment wire 25. The platform attachment wire 25 for fixing the towing work machine 4 is passed through the connection hole 7a of the connection part 7 of the fixing jig 1 and connected to the towing work machine 4.
[0088] 5, the traction machine 4 is operated to wind up the traction wire 23, thereby towing and pulling the legs 27 of the load (heavy load) 3 placed on the transport vehicle 24 in the lateral direction, and the load (heavy load) 3 is moved to the installation reference point R on the foundation 2 (step 5). When the front end face of the load (heavy load) 3 in the movement direction (the direction of arrow P in FIG. 5) reaches the installation reference point R on the foundation 2, the operation of winding up the traction wire 23 by the traction machine 4 is completed.
[0089] Next, the load (heavy load) 3 is lifted by heavy machinery such as a crane, and the transport vehicle 24 is separated from the load (heavy load) 3. After separation, the load (heavy load) 3 is placed on the foundation 2 (lowered and installed at an installation position on the foundation 2) (Step 6). Note that this Step 6 may be performed using a jack, as in the case of load moving method 2 described below.
[0090] Finally, the fixing jig 1, the towing work machine 4, the towing wire 23 and the base mounting wire 25 are removed (step 7).
[0091] According to the configuration of the load moving method 1 of this embodiment described above, the fixing jig 1 of this embodiment is used, so it is possible to arrange and fix the fixing jig 1 of the towing work machine 4 to the foundation 2 without damaging or breaking the foundation 2, and to move the load (heavy load) 3 that has been unloaded and placed on the foundation 2 to a predetermined installation position on the foundation 2 while towing it laterally. Therefore, according to the configuration of the load moving method 1 of this embodiment, there is no need to repair the foundation 2 after the load (heavy load) 3 has been placed and positioned on the foundation 2 and the towing work machine 4, etc. have been removed, as described above.
[0092] (Luggage Moving Method 2) Next, luggage moving method 2 using the fixing jig in this embodiment will be explained with reference to Figures 6 to 17, again using the case where the luggage is a transported item (e.g., a heavy item such as a transformer) as an example.
[0093] FIG. 6 is a side view illustrating the step of installing two horizontal rails on a foundation in method 2 of moving luggage using a fixing jig in this embodiment; FIG. 7 is a rear end view seen from the direction of arrow R in FIG. 6; FIG. 8 is a side view illustrating the step of attaching two legs to the underside of the luggage and the step of preparing and arranging a heavy-duty transport cart on the transport rails of a trailer in method 2 of moving luggage using the fixing jig; FIG. 9 is a rear end view seen from the direction of arrow R in FIG. 8; FIG. 10 is a side view illustrating the step of unloading the luggage onto the heavy-duty transport cart in method 2 of moving luggage using the fixing jig; 13 is a side view illustrating the step of moving the cargo again to the installation reference point on the foundation in the event that the cargo has passed the installation reference point on the foundation, in method 2 of moving cargo using the fixing jig; FIG. 14 is a side view illustrating the step of separating the heavy-duty transport cart from the cargo, and then removing the heavy-duty transport cart, lateral rail, and legs (H-shaped steel) in that order, in method 2 of moving cargo using the fixing jig; FIG. 15 is a front end view seen from the direction of arrow S in FIG. 14; FIG. 16 is a side view illustrating the step of placing the cargo on the foundation in method 2 of moving cargo using the fixing jig; and FIG. 17 is a front end view seen from the direction of arrow S in FIG. 16.
[0094] As shown in Figures 6 to 17, the method 2 for moving cargo in this embodiment is also a method for moving cargo in which the fixing jig 1 shown in Figures 1 to 3 is used to tow cargo 52, such as an object to be transported (e.g., a heavy object such as a transformer) placed on a foundation 2, and the cargo (heavy object) 52 is moved on the foundation 2.
[0095] As shown in FIGS. 6 and 7 , initially, a load 52, such as a transported object (e.g., a heavy object such as a transformer), is placed on conveyance rails 51 a, 51 b provided on a trailer 50. The trailer 50, which is parked next to a foundation 2, is separated from the foundation 2 by a predetermined distance. The load (heavy object) 52 has two legs 27 (27 a, 27 b) on its bottom surface. The legs 27 a, 27 b are made of, for example, H-shaped steel. The two legs 27 a, 27 b are arranged parallel to each other and spaced a predetermined distance (L1′). First, as shown in FIG. 6 , two parallel lateral rails 32 a, 32 b (the lateral rail 32 a is not shown) are installed on the foundation 2 to bridge the trailer 50 and the foundation 2 and reach the installation position of the load (heavy object) 52 on the foundation 2 (Step 1). As shown in FIGS. 6 and 7, the lateral pulling rails 32a and 32b are connected to (in contact with) the transport rails 51a and 51b of the trailer 50, respectively.
[0096] Furthermore, when the transport rails 51a, 51b of the trailer 50 are arranged parallel to each other with a predetermined distance (L1) between their centers, the lateral rails 32a, 32b are also installed on the foundation 2 so that they are parallel to each other with a predetermined distance (L1) between their centers. The installed lateral rails 32a, 32b have, for example, a rectangular cross section that extends linearly, and are made of a material (e.g., steel) that has sufficient load-bearing capacity to support the load (heavy object) 52. The distance L1 is approximately the same as the distance L1' between the two legs 27a, 27b.
[0097] 8 and 9, the cargo (heavy load) 52 is lifted upward inside the trailer 50 using jacks 30a and 30b, and heavy load transporting carts (hereinafter referred to as "transport vehicles") 26a and 26b are prepared and positioned on the transport rails 51a and 51b of the trailer 50 (Step 2). In this embodiment, as an example, protrusions 52a and 52b that serve as jack-up points are provided on the outside of the cargo (heavy load) 52.
[0098] 10 and 11, the cargo (heavy object) 52 having legs 27a and 27b is jacked down using jacks 30a and 30b and unloaded onto transport vehicles 26a and 26b placed on transport rails 51a and 51b of the trailer 50. The cargo (heavy object) 52 is placed on the transport vehicles 26a and 26b via the legs 27a and 27b (Step 3).
[0099] In step 6, which will be described later, it is preferable to prevent the position of the heavy object 52 on the transport vehicles 26a, 26b from shifting and causing at least a portion of the heavy object 52 to fall off the transport vehicles 26a, 26b. For this reason, the transport vehicles 26a, 26b and the legs 27a, 27b are appropriately fixed by fixing means (not shown). This fixes the heavy object 52 to the transport vehicles 26a, 26b.
[0100] Next, as shown in Fig. 12 , the fixing jig 1 is placed and fixed to the foundation 2 (step 4). More specifically, the first leg 10 and the second leg 11 of the fixing jig 1 are fitted into a pit 9 provided in the foundation 2 so that the plane to which the connection portion 7 of the wall portion 6 of the fixing jig 1 is welded faces the load (heavy object) 52, thereby placing and fixing the fixing jig 1 to the foundation 2. Even more specifically, as shown in Fig. 1 , after adjusting the distance Wb between one surface of the first leg 10 and the other surface of the second leg 11 of the fixing jig 1 to match the width WP of the pit 9, the first leg 10 and the second leg 11 (two fixing legs) are fitted into the pit 9 provided in the foundation 2, thereby placing and fixing the fixing jig 1 to the foundation 2.
[0101] According to this method of positioning and fixing the fixing jig 1, it is possible to position and fix the fixing jig 1 to the foundation 2 without damaging or breaking the foundation 2, so that, as described below, there is no need to repair the foundation 2 after the cargo (heavy object) 52 has been placed and positioned on the foundation 2 and the towing work machine 4, etc. has been removed.
[0102] Next, as also shown in FIG. 12 , the traction implement 4 is fixed to the fixing jig 1, and one end (free end) of the traction wire 23 extending from the traction implement 4 is tied to the leg 27 a and / or 27 b (step 5). More specifically, the traction implement 4 is fixed to the fixing jig 1 via the platform attachment wire 25, and one end (free end) of the traction wire 23 extending from the traction implement 4 is tied to two transport vehicles 26 a, 26 b positioned forward in the direction of movement of the load (heavy object) 52 (the direction of arrow P; the X-axis direction). Note that the one end of the traction wire 23 is tied to the legs 27 a, 27 b so that the traction force acts equally on the two legs 27 a, 27 b. The platform attachment wire 25 for fixing the traction implement 4 is passed through the connection hole 7 a of the connection portion 7 of the fixing jig 1 and connected to the traction implement 4.
[0103] 12, the towing machine 4 is operated to reel in the towing wire 23, thereby towing and pulling the load (heavy load) 52 placed on the transport vehicles 26a, 26b via their legs 27a, 27b in the horizontal direction. As a result, the load (heavy load) 52 is pulled laterally by the transport vehicles 26a, 26b, and moves along the transport rails 51a, 51b of the trailer 50, the transport rails 51a, 51b, and the subsequent lateral pulling rails 32a, 32b (Step 6). The widths of the transport rails 51a, 51b and the lateral pulling rails 32a, 32b in the Y-axis direction are set wide enough to prevent the transport vehicles 26a, 26b from coming off the transport rails 51a, 51b and the lateral pulling rails 32a, 32b while the load (heavy load) 52 is being pulled laterally.
[0104] When the front end face of the cargo (heavy object) 52 in the direction of movement (arrow P direction; X-axis direction) reaches the installation reference point R on the foundation 2, the traction work machine 4 ends the winding operation of the traction wire 23 (step 7).
[0105] Furthermore, when the cargo (heavy object) 52 loaded on the transport vehicle 26a, 26b is towed and moved laterally (in the X-axis direction), if the front end face of the cargo (heavy object) 52 passes through the installation reference point R on the foundation 2, or if the space between the fixing jig 1 and the cargo (heavy object) 52 becomes so narrow that the towing work machine 4 cannot be installed between the fixing jig 1 and the cargo (heavy object) 52, the cargo (heavy object) 52 is moved to the installation reference point R as follows.
[0106] That is, first, the towing implement 4 is removed (step 8). Next, the fixing jig 1 is removed from the pit 9 provided in the foundation 2 (step 9), and then, as shown in Fig. 13, the first leg 10 and the second leg 11 of the fixing jig 1 are fitted into the pit 9 provided in the foundation 2 so that the flat surface of the fixing jig 1 opposite to the flat surface to which the connection portion 7 of the wall portion 6 is welded faces the load (heavy object) 52, thereby repositioning and fixing the fixing jig 1 to the foundation 2 (step 10).
[0107] 13 , a jack 29 is placed between the load (heavy load) 52 and the flat surface of the wall 6 of the fixing jig 1 opposite to the flat surface to which the connection portion 7 is welded (step 11). The jack 29 is placed, for example, between the wall 6 and the end faces of two legs (H-shaped steel) 27a, 27b attached to the underside of the load (heavy load) 52. Note that one end of the jack 29 is connected to the end faces of the two legs (H-shaped steel) 27a, 27b so that the pressing force of the jack 29 acts equally on the end faces of the two legs (H-shaped steel) 27a, 27b.
[0108] 13, the jack 29 is driven (see arrow A in FIG. 13) to press the load (heavy load) 52 in the -X-axis direction, thereby moving the load (heavy load) 52 from a position beyond the installation reference point R to the installation reference point R (step 12). Next, the jack 29 is removed.
[0109] Next, as shown in Figures 14 and 15, the cargo (heavy object) 52 that has been moved to the installation reference point R on the foundation 2 is lifted upward using jacks 30a, 30b, and the transport vehicles 26a, 26b are separated from the cargo (heavy object) 52. After separation, the transport vehicles 26a, 26b and the lateral rails 32a, 32b are removed in that order (step 14).
[0110] Next, as shown in Figures 16 and 17, the cargo (heavy object) 52 is jacked down and placed on the foundation 2 via the legs 27a, 27b (lowered and installed at the installation position on the foundation 2) (step 14).
[0111] Finally, the fixing jig 1, the towing work machine 4, the towing wire 23 and the base mounting wire 25 are removed (step 15).
[0112] According to the configuration of the load moving method 2 of this embodiment described above, the fixing jig 1 of this embodiment is used, so it is possible to position and fix the fixing jig 1 of the towing work machine 4 to the foundation 2 without damaging or breaking the foundation 2, and to move the load (heavy load) 52 that has been unloaded and placed on the foundation 2 to a predetermined installation position on the foundation 2 while towing it laterally. Therefore, according to the configuration of the load moving method 2 of this embodiment, as described above, there is no need to repair the foundation 2 after the load (heavy load) 52 has been placed and positioned on the foundation 2 and the towing work machine 4, etc. have been removed. In addition, because the moving distance of the load (heavy load) 52 can be finely adjusted using the jack 29, it is possible to reliably and easily install the load (heavy load) 52 at a predetermined installation position on the foundation 2.
[0113] In the present embodiment, an example has been described in which an electric winch is used as the traction implement 4. However, the present invention is not necessarily limited to this configuration. For example, a manual winch (e.g., Chillhall (registered trademark)) as shown in FIG. 18 may be used as the traction implement 4. The manual winch allows the worker W to tilt a rod-shaped operating handle H in a plane parallel to the X-Z plane (see double arrows A and B) to wind up the traction wire 23. Use of this manual winch allows fine adjustment of the winding length of the traction wire 23, making it possible to reliably and easily install the load (heavy object) 52 at a predetermined installation position on the foundation 2.
[0114] In addition, in this embodiment, an example has been described in which elongated holes extending in the direction in which the towing work implement 4 is towed are drilled in the base 5 at two locations on both ends of the base 5 that are approximately perpendicular to the longitudinal direction of the elongated holes (elongated holes 12a, 12b). However, the present invention is not necessarily limited to this configuration. It is sufficient that the base 5 has elongated holes extending in the direction in which the towing work implement 4 is towed at least two locations that are approximately perpendicular to the longitudinal direction of the elongated holes, and there are no particular limitations on the locations or number of the elongated holes.
[0115] In addition, in this embodiment, the positioning member 13 is provided with an upright portion 13a having a surface that is approximately perpendicular to the contact surface that contacts the upper surface of the base 5, and the upright portion 13a is provided with third holes 18 at two locations, one in the longitudinal direction of the elongated hole and one in the direction approximately perpendicular to the longitudinal direction of the elongated hole. However, the present invention is not necessarily limited to this configuration. It is sufficient that the upright portion has third holes at at least two locations, one in the longitudinal direction of the elongated hole and one in the direction approximately perpendicular to the longitudinal direction of the elongated hole, and there are no particular limitations on the locations or number of third holes.
[0116] In addition, in this embodiment, the other ends of the long threaded portions 19 a, 19 b are supported by long threaded portion support members 21 a, 21 b provided at the end opposite the welded portion to the wall portion 6 of the base plate 5 (the end opposite the connection portion 7). However, the present invention is not necessarily limited to this configuration. The long threaded portion support members may be provided near the end opposite the connection portion of the base plate.
[0117] In addition, in this embodiment, the case where the luggage (heavy object) 52 has legs 27a, 27b on its underside has been described as an example. However, the present invention is not necessarily limited to this configuration and can also be applied to luggage (heavy object) 52 that does not have legs 27a, 27b on its underside. That is, in step 2, after the luggage (heavy object) 52 is lifted upward using the jacks 30a, 30b, and before the transport vehicles 26a, 26b are prepared and positioned, two transport guides (H-shaped steel beams) having the same shape as the legs 27a, 27b may be attached to the underside of the luggage (heavy object) 52 so that they are parallel to each other and spaced a predetermined distance (L1') from each other.
[0118] The function of this transport guide is the same as that of legs 27a, 27b in each step described above. That is, the load (heavy load) 52 is placed on transport vehicles 26a, 26b via the transport guide. The transport guide is appropriately fixed to transport vehicles 26a, 26b by fixing means (not shown) and is connected to one end of traction wire 23. Finally, in step 14, transport vehicles 26a, 26b are separated from the load (heavy load) 52, and after separation, the transport vehicles 26a, 26b, lateral pulling rails 32a, 32b, and transport guide are removed in this order.
[0119] (Configuration of Alternative Fixing Jig) First, the configuration of an alternative fixing jig (hereinafter simply referred to as "fixing jig") for the towing work machine in the first embodiment will be described with reference to Figs. 19 and 20. Figs.
[0120] FIG. 19 is a plan view showing a specific configuration of a fixing jig 100 according to another embodiment of the present invention, and FIG. 20 is a perspective view showing a specific configuration of the fixing jig 100. As shown in FIG.
[0121] As shown in FIGS. 19 and 20 , the fixing jig 100 of this embodiment has substantially the same configuration as the fixing jig 1 described above, and includes components corresponding to the base 5, support portions 5a and 5b, wall portion 6, connection portion 7 having connection hole portion 7a, fixing portion 8, first leg portion 10, second leg portion 11, long hole portions 12a and 12b, positioning member 13 including standing portion 13a, positioning bolts 16a and 16b, positioning nuts 17a and 17b, positioning member fixing long threaded portions 19a and 19b, positioning member fixing nuts 20a and 20b, long threaded portion support members 21a and 21b, gripping portions 22a and 22b, and nuts 40a and 40b in the fixing jig 1 shown in FIGS. 1 to 3 , respectively. The device includes a base 105, support portions 105a and 105b, a wall portion 106, a connection portion 107 having a connection hole portion 107a, a fixing portion 108, a first leg portion 110, a second leg portion 111, long hole portions 112a and 112b, a positioning member 113 including a standing portion 113a, positioning bolts 116a and 116b, positioning nuts 117a and 117b (not shown), long threaded portions 119a and 119b for fixing the positioning member, nuts 120a and 120b for fixing the positioning member, long threaded portion support members 121a and 121b, gripping portions 122a and 122b, and nuts 140a and 140b.
[0122] 19 and 20 , unlike support portion 5a of fixing jig 1, support portion 105a of fixing jig 100 is provided on the left and right side surfaces (Y-axis direction) of fixing jig 100, and one end of support portion 105a extends beyond wall portion 106 toward the back surface (X′-axis direction) of fixing jig 100. Furthermore, each component member may be made lighter, for example, bent plate-shaped gripping portions 122a and 122b, or notched erecting portion 113a.
[0123] With the above configuration, the fixing jig 100 is lighter, more stable, and easier to handle. It can be used in place of the fixing jig 1 in the movement method 1 or movement method 2 of this embodiment shown in Figures 1 and 5 to 18, and can achieve the same effects as the fixing jig 1.
[0124] Second Embodiment (Configuration of Fixing Jig) Next, the configuration of a fixing jig in this embodiment will be described with reference to FIGS. 21 and 22. FIG.
[0125] FIG. 21 is an explanatory diagram showing an example of use of the fixing jig in this embodiment ((a) is a side view, (b) is a plan view), and FIG. 22 is a diagram showing a specific configuration of the fixing jig ((a) is a plan view, (b) is a side view, and (c) is a cross-sectional view taken along the line (c)-(c) in (b)).
[0126] As shown in FIG. 21 , the fixing jig 33 of this embodiment is a jig used to fix a traction implement 4 that tows a load 3 placed on a foundation 2 to move the load 3 on the foundation 2. One end (free end) of a traction wire 23 extending from the traction implement 4 is fastened to the load 3. The other end of the traction implement 4 is connected to the fixing jig 33 via a platform mounting wire (fixing tool) 25. The traction implement 4 is operated to wind up the traction wire 23, thereby towing the load 3 and moving the load 3 toward a predetermined installation position on the foundation 2 (in the direction of arrow P). In FIG. 21 , R indicates an "installation reference point" that serves as a reference for the installation position where the load 3 is to be installed. When the front end face of the load 3 in the movement direction (direction of arrow P) reaches the installation reference point R, the traction implement 4 terminates the operation of winding up the traction wire 23.
[0127] The foundation 2 is made of concrete or the like. The cargo 3 is an object to be transported (for example, a heavy object such as a transformer). For example, a winch can be used as the traction implement 4. In this embodiment, an electric winch is used as the traction implement 4. However, as in the first embodiment, a manual winch (for example, Chillhall (registered trademark)) can also be used.
[0128] As shown in Figures 21 and 22, the basic configuration of the fixing jig 33 includes a rectangular plate-shaped base 34 that is placed on the foundation 2, a wall portion 36 that is fixed to the base 34 and has a plane that extends in a direction approximately perpendicular to a plane that includes the installation surface of the base 34, a connection portion 35 that is connected to the towing work machine 4 and fixes the towing work machine 4, and is fixed to the plane that extends in the approximately perpendicular direction of the wall portion 36, and a fixing portion 37 (see Figure 21(a)) that comes into contact with the foundation 2 and restricts movement of the fixing jig 33 in the towing direction of the towing work machine 4 (the direction opposite to the direction of arrow P in Figure 21).
[0129] Here, the "installation surface of the base 34" refers to the surface that is installed on (comes into contact with) the upper surface of the foundation 2 when the fixing jig 33 is placed and fixed to the foundation 2. The wall portion 36 has a flat surface that extends in a direction approximately perpendicular to the plane that includes the installation surface of the base 34. The connection portion 35 is provided on the side of the wall portion 36 that faces the load 3, and is connected to the towing work machine 4 via the platform attachment wire 25 (fixing device). The connection portion 35 has a connection hole 35a drilled therein for connection to the platform attachment wire 25 (fixing device).
[0130] According to the configuration of the fixing jig 33 of this embodiment, in particular, by being provided with a fixing portion 37 that comes into contact with the foundation 2 and restricts the movement of the fixing jig 33 in the direction of towing by the towing work machine 4, it is possible to provide a fixing jig 33 that can be positioned and fixed to the foundation 2 without damaging or breaking the foundation 2.
[0131] 21 and 22 , the plane of the wall portion 36, which extends in a direction substantially perpendicular to the plane including the installation surface of the base 34, extends toward both the upper surface and the installation surface of the base 34. The fixing portion 37 is made up of the installation surface of the base 34 and the plane of the wall portion (fixing wall portion) 36 extending toward the installation surface of the base 34. Furthermore, the installation surface of the base 34 and the plane of the wall portion (fixing wall portion) 36 extending toward the installation surface of the base 34 form a substantially right angle with each other so that the fixing portion 37 comes into contact with both the upper surface and the front end surface of the foundation, which form the corners of the foundation 2.
[0132] With this configuration, it is possible to restrict movement of the fixing jig 33 in the towing direction of the towing implement 4 simply by bringing the installation surface of the base 34 and the flat surface of the wall portion (fixing wall portion) 36 extending toward the installation surface of the base 34 into contact with both the foundation upper surface and the foundation front end surface forming the corners of the foundation 2. Therefore, with this configuration, it is possible to realize a fixing jig 33 with a simple and low-cost configuration that can be positioned and fixed to the foundation 2 without damaging or breaking the foundation 2.
[0133] This will be explained in more detail below. As shown in Figure 22, the wall 36 is made of steel (channel steel) with a channel structure. The base 34 is made of steel in the shape of a rectangular plate. One end face (parallel to the Y-Z plane) of the base 34 is welded to the surface of the wall 36 (parallel to the Y-Z plane; web portion of the channel steel) so that the surface of the wall 36 extending in the Z-axis direction (web portion of the channel steel) and the base 34 extending in the X-axis direction are approximately perpendicular. The welded surface is located at a predetermined position on the surface of the wall 36, spaced from the end of the wall 36, so that the distance from either the upper or lower end of the wall 36 (the upper end in Figure 22) to the installation surface (lower surface) of the base 34 is a predetermined distance (L0).
[0134] 22 , a connection part 35 is provided on the surface of the wall part 36 that includes the welding surface with the base 34. The connection part 35 is connected to the towing work machine 4 via the mounting wire (fixture) 25 of the towing work machine 4. The connection part 35 is made of a plate-shaped steel material, and is provided with a connection hole 35a for connection to the mounting wire 25 (fixture).
[0135] The plate-shaped connecting portion 35 has at least one side surface that forms a right angle, and one side of the side surface that forms a right angle is welded to the surface of the wall portion 36 that includes the welding surface with the base 34, and the other side of the side surface that forms a right angle is welded to the upper surface (top surface) of the base 34. The connecting hole portion 35a is formed as a through-hole in a surface of the connecting portion 35 that is parallel to the X-Z plane.
[0136] An upper support plate 39 is provided on the upper surface side of the plate-shaped connecting portion 35. The side surface of the upper support plate 39 is the upper end portion of the wall portion 36 and is welded to the surface of the wall portion 36, and the lower surface (lower face) of the upper support plate 39 is welded to the upper surface of the plate-shaped connecting portion 35.
[0137] That is, the plate-shaped connecting portion 35 is supported by the base 34, the wall portion 36, and the upper support plate 39. With this configuration, the connecting portion 35 is made strong, and it is possible to realize a fixing jig 33 that can sufficiently withstand the pulling of a heavy object such as a transformer.
[0138] Here, the length of the upper support plate 39 in the X-axis direction is set shorter than the length of the base 34 in the X-axis direction. With this configuration, the worker can easily visually confirm the position of the connection hole 35a of the connection part 35 from above, making it easier to connect the connection part 35 and the towing work machine 4.
[0139] The strength of the connecting portion 35 may be appropriately reinforced by two side support plates 41, 42. One side support plate 41 is welded to one of the surfaces parallel to the X-Z plane of the plate-shaped connecting portion 35, and the other side support plate 42 is welded to the other surface parallel to the X-Z plane of the plate-shaped connecting portion 35. Through holes 41 a, 42 a are formed in the two side support plates 41, 42, respectively, and when the side support plates 41, 42 are welded to the plate-shaped connecting portion 35, the central axes of the through holes 41 a, 42 a become substantially coaxial with the central axis of the connecting hole 35 a formed in the plate-shaped connecting portion 35.
[0140] 21 and 22, which utilizes the corner of the foundation 2, differs from the fixing jig 1 shown in Figures 1 to 3, which is fixed by fitting into the pit 9 of the foundation 2, in that the fixing jig 33 is supported and fixed by the top surface and front end surface of the foundation, which form the corner of the foundation 2, and therefore has a slightly weaker fixing force than the fixing jig 1 which utilizes the pit 9 of the foundation 2. Therefore, depending on the weight of the cargo (heavy object) 3, there is a considerable risk that the fixing jig 33 will come off the corner of the foundation 2 during the towing operation.
[0141] In order to avoid such problems as much as possible, it is necessary to appropriately determine the length by which the wall portion 36 extends below the installation surface of the base 34, the area in contact with the front end surface of the foundation 2, the area of the installation surface of the base 34 in contact with the upper surface of the foundation 2, etc. By appropriately determining the area in which the wall portion (fixing wall portion) 36 contacts the front end surface of the foundation 2, etc., it becomes possible to firmly hold the wall portion (fixing wall portion) 36 constituting the fixing jig 33 to the front end surface of the foundation 2 during the operation of pulling the cargo 3 sideways. Therefore, there is no need to drive anchor bolts or the like to fix the wall portion (fixing wall portion) 36 to the front end surface of the foundation 2, and the risk of damaging or breaking the foundation 2 is reduced.
[0142] In this embodiment, as shown in FIG. 22 , extension walls 38 are provided on a portion of the plane of the wall (fixing wall) 36 extending toward the installation surface of the base 34, extending in a direction substantially perpendicular to the direction of extension toward the installation surface of the base 34. More specifically, two extension walls 38, one on each side, are provided on the lower end of the wall (fixing wall) 36, which is made of channel-structured steel (channel steel). The extension walls 38 are made of unequal angle steel (unequal angles) and are welded to the side portions (flange portions of the channel steel) of the wall (fixing wall) 36. The welded surfaces of the extension walls 38 are parallel to the X-Z plane of the unequal angle steel, and the surface of the extension wall 38 (unequal angles) parallel to the Y-Z plane is positioned substantially flush with the surface of the wall (fixing wall) 36 (web portion of the channel steel). With this configuration, it is possible to increase the area (contact area) of the portion (wall portion (fixing wall portion) 36) of the fixing portion 37 that comes into contact with the front end surface of the foundation 2, and therefore it is possible to firmly hold the wall portion (fixing wall portion) 36 on the front end surface of the foundation 2. As a result, it is possible to minimize the risk that the fixing jig 33 will come off the corner of the foundation 2 during the towing operation.
[0143] 23 , in cases where the corner of the foundation 2 where the fixing jig 33 is arranged and fixed is in contact with the ground, a stake 55 may be driven into the vicinity of the back side of the wall 36 (the side opposite to the side where the connection part 35 for connecting to the towing work machine 4 is provided) to strengthen the fixation of the fixing jig 33. In other words, by driving the stake 55 into the vicinity of the back side of the wall 36 in this way, it is possible to reduce the risk that the stake 55 will become an obstacle and cause the fixing jig 33 to come off the corner of the foundation 2 during the towing operation.
[0144] The method of moving a load using the fixing jig 33 of this embodiment described above is substantially the same as the method of moving a load using the fixing jig 1 of the above-described embodiment 1. The following description will focus on the differences from the above-described embodiment 1, and a description of the similarities will be omitted.
[0145] (Luggage Moving Method 3) The following description with reference to FIG. 24 corresponds to steps 3 to 5 in luggage moving method 1 using the fixing jig 1 of the first embodiment.
[0146] Figure 24 is a side view illustrating the steps of method 3 of moving cargo using a fixing jig in this embodiment, from the step of placing and fixing the fixing jig to the foundation to the step of moving the cargo to the installation reference point on the foundation.
[0147] 24 , a fixing jig 33 is placed and fixed to the foundation 2 (step 3′). More specifically, the installation surface of the base 34 and the flat surface of the wall portion (fixing wall portion) 36 extending toward the installation surface of the base 34, which form approximately a right angle with each other, are brought into contact with the top surface and front end surface of the foundation, which form the corner of the foundation 2, respectively, and the fixing jig 33 is placed and fixed to the corner of the foundation 2.
[0148] According to this method of positioning and fixing the fixing jig 33, it is possible to position and fix the fixing jig 33 to the foundation 2 without damaging or breaking the foundation 2, so there is no need to repair the foundation 2 after the cargo (heavy object) 3 has been placed and positioned on the foundation 2 and the towing machine 4, etc. has been removed.
[0149] 24 , the towing work machine 4 is fixed to the fixing jig 33, and one end (free end) of the towing wire 23 extending from the towing work machine 4 is tied to the legs 27a, 27b of the load (heavy object) 3 (step 4'). More specifically, the towing work machine 4 is fixed to the fixing jig 33 via the platform attachment wire 25. The platform attachment wire 25 for fixing the towing work machine 4 is passed through the connection hole 35a of the connection part 35 of the fixing jig 33 and connected to the towing work machine 4.
[0150] 24, the traction machine 4 is operated to wind up the traction wire 23, thereby towing and pulling the load (heavy load) 3 placed on the transport vehicle 24 in the sideways direction, and the load (heavy load) 3 is moved to the installation reference point R on the foundation 2 (step 5'). When the front end face of the load (heavy load) 3 in the movement direction (the direction of arrow P in FIG. 24) reaches the installation reference point R on the foundation 2, the operation of winding up the traction wire 23 by the traction machine 4 is completed.
[0151] According to the configuration of the load moving method 3 of this embodiment described above, the fixing jig 33 of this embodiment is used, so it is possible to arrange and fix the fixing jig 33 of the towing work machine 4 to the foundation 2 without damaging or breaking the foundation 2, and to move the load (heavy load) 3 that has been unloaded and placed on the foundation 2 to a predetermined installation position on the foundation 2 while towing it laterally. Therefore, according to the configuration of the load moving method 3 of this embodiment, there is no need to repair the foundation 2 after the load (heavy load) 3 has been placed and positioned on the foundation 2 and the towing work machine 4, etc. have been removed, as described above.
[0152] (Load Moving Method 4) The following description with reference to FIG. 25 corresponds to steps 4 to 7 in the load moving method 2 using the fixing jig 1 of the first embodiment.
[0153] Figure 25 is a side view illustrating the steps of method 4 of moving cargo using a fixing jig in this embodiment, from the step of placing and fixing the fixing jig to the foundation to the step of moving the cargo to the installation reference point on the foundation.
[0154] 25 , a fixing jig 33 is placed and fixed to the foundation 2 (step 4′). More specifically, the installation surface of the base 34 and the flat surface of the wall portion (fixing wall portion) 36 extending toward the installation surface of the base 34, which form approximately a right angle with each other, are brought into contact with the top surface and front end surface of the foundation, which form the corner of the foundation 2, respectively, and the fixing jig 33 is placed and fixed to the corner of the foundation 2.
[0155] According to this method of positioning and fixing the fixing jig 33, it is possible to position and fix the fixing jig 33 to the foundation 2 without damaging or breaking the foundation 2, so there is no need to repair the foundation 2 after the cargo (heavy object) 52 has been placed and positioned on the foundation 2 and the towing machine 4, etc. has been removed.
[0156] 25 , the towing work machine 4 is fixed to the fixing jig 33, and one end (free end) of the towing wire 23 extending from the towing work machine 4 is tied to the load (heavy object) 52 (step 5′). More specifically, the towing work machine 4 is fixed to the fixing jig 33 via the platform mounting wire 25, and one end (free end) of the towing wire 23 extending from the towing work machine 4 is tied to the two transport vehicles 26a, 26b located forward in the direction of movement of the load (heavy object) 52 (direction of arrow P; X-axis direction). Note that the one end of the towing wire 23 is tied to the two transport vehicles 26a, 26b so that a tractive force acts equally on the two transport vehicles 26a, 26b.
[0157] 25, the towing work machine 4 is operated to wind up the towing wire 23, thereby towing and pulling the load (heavy load) 52 placed on the transport vehicles 26a, 26b in the lateral direction. As a result, the load (heavy load) 52 moves via the transport vehicles 26a, 26b on the transport rails 51a, 51b of the trailer 50 and the lateral pulling rails 32a, 32b connected to the transport rails 51a, 51b (step 6').
[0158] When the front end face of the cargo (heavy object) 52 in the direction of movement (arrow P direction; X-axis direction) reaches the installation reference point R on the foundation 2, the traction work machine 4 ends the winding operation of the traction wire 23 (step 7').
