Description

[Technical field]

[0001] The present disclosure relates to a transport device, a track for use with the transport device, and a method for moving a payload. [Background technology]

[0002] A transport device equipped with a rail and a towing vehicle that moves along the rail is in use (see Patent Document 1). Such a transport device is also called a monorail, and the rail is installed on steeply inclined ground, and a cart is pulled by the towing vehicle. It is used for transporting materials for agriculture and forestry in mountainous areas, construction and civil engineering, and leisure purposes. There are two types of transport devices: single-rail type with one rail, and double-rail type with multiple rails. Of these, the single-rail type has a limit on the maximum weight that can be transported at one time due to strength issues, making it difficult to place heavy objects such as heavy machinery on it. For this reason, double-rail type transport devices with three rails, for example, have been used to transport heavy objects.

[0003] However, dual-rail transport devices are expensive to install, and the rails have little flexibility in bending up, down, left, and right, so there are limitations on where they can be installed. For example, cutting timber is sometimes required to secure space to install the tracks.

[0004] Therefore, in order to transport heavy objects using a single-rail type that is inexpensive and has a high degree of freedom in installation, it is possible to consider disassembling the heavy objects to reduce their weight and transporting them in multiple trips.

[0005] However, even in this case, the heavy objects must be loaded onto the cart, and since transport devices such as monorails are often installed in mountainous areas with steep slopes, it is difficult to transport the equipment required for loading and unloading the heavy objects.In addition, since single-rail type transport devices have only one rail, there is a possibility that the cart will tilt to the left or right if the weight balance is poor when it is placed on the ground.

[0006] [Patent Document 1] JP 2008-21162 A Summary of the Invention [Problem to be solved by the invention]

[0007] One of the objectives of one embodiment of the present disclosure is to provide a transport device and a track for the transport device, and a method for moving a loaded object, which are capable of transporting heavy objects. Another objective of another embodiment is to provide a transport device and a track for the transport device, and a method for moving a loaded object, which make it easier to load and unload a loaded object onto a single-rail transport device. Yet another objective of another embodiment is to provide a transport device and a track for the transport device, and a method for moving a loaded object, which make it easier to maintain balance when loading and unloading a loaded object onto a single-rail transport device. Note that the description of these objectives does not preclude the existence of other objectives. Also, it is not necessary for one embodiment of the present disclosure to solve all of these objectives. Furthermore, it is possible to extract other objectives from the description of the specification, drawings, claims, etc. of this disclosure. Means for solving the objectives and effects of the invention

[0008] The transport device according to the first embodiment is a transport device including a rail and a transporter having a platform for placing a load that can move along the rail, and includes a cross bar that is fixed to a part of the rail in a position in which a plurality of bars are spaced apart from each other along the extension direction of the rail and each crosses the rail and extends to the left and right of the rail, a pair of guide bars that are fixed to the ends of the cross bar and extend parallel to the rail, a gate section that is slidably attached to the pair of guide bars and bridges the rail above the rail so as to cross the rail, and a crane section that is provided on the gate section and can move up and down above the platform. With the above configuration, by providing a gantry crane type crane section on a part of the rail, it is possible to use the crane section to load and unload the load.

[0016] Furthermore, a ninth embodiment of the track for a transport device is a track for a transport device for moving a transport machine having a platform for placing a load along a rail, the track comprising: a rail, a cross bar provided on a part of the rail along the extension direction of the rail, the cross bar being fixed in a position in which the cross bar is spaced apart from the other and each crosses the rail and extends to the left and right of the rail, a pair of guide bars fixed to the ends of the cross bar and extending parallel to the rail, a gate section slidably attached to the pair of guide bars and bridging the rail above the rail so as to cross the rail, and a crane section provided on the gate section and capable of moving up and down above the rail. With the above configuration, by providing a gantry crane type crane section on a part of the rail, it becomes possible to use the crane section to load and unload the load. Even in places where it is difficult to bring in equipment to assist with loading and unloading operations, by incorporating a crane unit into the transport device itself, it is possible for the transport device itself to complete the loading and unloading operations, thereby improving convenience.

[0017] Furthermore, a method for moving a loaded object using a conveying device according to a tenth embodiment is a method for moving a loaded object using a conveying device for moving a loaded object from a first point to a second point along a rail by a conveying machine, the method including the steps of: disassembling the loaded object into a first part and a second part; lifting the first part onto the placement table using a first crane unit that is movable up and down above the placement table, the first crane unit being provided in a first gate unit that bridges above the rail to cross the rail, the first crane unit being fixed to ends of first cross bars that are fixed in a position along the extension direction of the rail at the first point so as to be spaced apart from each other and to extend to the left and right of the rail and that are slidably attached to a pair of first guide bars that extend parallel to the rail, and that are provided in a first gate unit that bridges above the rail to cross the rail, the first crane unit being movable up and down above the placement table, and the placement table with the first part placed thereon being lifted up and placed onto the placement table using a first crane unit that is movable up and down above the placement table, the first crane unit being provided in a first gate unit that bridges above the rail to cross the rail, the first crane unit being fixed to ends of first cross bars that are fixed in a position so as to cross the rail and extend to the left and right of the rail and that are slidably attached to ends of first cross bars that extend parallel to the rail and that are fixed to ends of first cross bars that are fixed in a position so as to cross the rail and extend to the left and right of the rail and that are slidably attached to ends of first cross bars that are fixed The method includes the steps of: moving the first part from the first point to the second point with a conveyor; lifting the first part and lowering it from the stand using a second crane unit that is slidably attached to a pair of second guide bars that extend parallel to the rail and is provided in a second gate unit that bridges the rail above the rail so as to cross the rail, and that can move up and down above the stand; moving the conveyor from the second point to the first point; moving the second part from the first point to the second point with the conveyor; and assembling the first part and the second part at the second point. By providing a gantry crane type crane unit on a part of the rail, it is possible to use the crane unit to load and unload the load. Even in places where it is difficult to bring in equipment to assist with loading and unloading operations, by incorporating a crane unit into the transport device itself, it is possible for the transport device itself to complete the loading and unloading operations, thereby improving convenience.

[0018] Furthermore, the method for moving a loaded object according to an eleventh embodiment is the same as the above embodiment, and further includes, between the step of hoisting the first part and placing it on the platform and the step of moving the platform from the first point to the second point by the transporter, a step of disassembling the first cross bar, the first guide bar, the first gate portion, and the first crane portion and placing them on the platform, and further includes the steps of moving the platform from the first point to the second point by the transporter and moving the first part on the platform. and a step of lowering the first part from the platform and assembling the first cross bar, the first guide bar, the first gate portion, and the first crane portion, between the step of lowering the first part from the platform, wherein in the step of lowering the first part from the platform, the first cross bar and the second cross bar are the same member, the first guide bar and the second guide bar are the same member, the first gate portion and the second gate portion are the same member, and the first crane portion and the second crane portion are the same member.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] The present disclosure will be described in more detail below with reference to the drawings. In the following description, terms indicating specific directions or positions (e.g., "upper", "lower", and other terms including these terms) are used as necessary, but the use of these terms is for the purpose of facilitating understanding of the invention with reference to the drawings, and the meaning of these terms does not limit the technical scope of the present disclosure. In addition, parts with the same reference numerals appearing in multiple drawings indicate the same or equivalent parts or members.

[0021] Furthermore, the embodiments shown below are specific examples of the technical ideas of the present disclosure, and do not limit the present disclosure to the following. Furthermore, unless otherwise specified, the dimensions, materials, shapes, relative positions, etc. of the components described below are intended to be illustrative and not to limit the scope of the present disclosure. Furthermore, the contents described in one embodiment can be applied to other embodiments. Furthermore, the sizes and positional relationships of the components shown in the drawings may be exaggerated to clarify the explanation. [Embodiment 1]

[0022] 1 to 4 show a transporting device 100 according to embodiment 1. In these figures, Fig. 1 is a schematic side view showing the transporting device 100 according to embodiment 1, Fig. 2 is an enlarged schematic side view showing loading of a first part PT1 at a first point in Fig. 1, Fig. 3 is an enlarged schematic side view showing unloading of the first part PT1 at a second point in Fig. 1, and Fig. 4 is a perspective view showing loading and unloading of an object WK by the transporting device 100 according to embodiment 1. (Transporter 10)

[0023] The transport device 100 shown in Figs. 1 to 4 includes a rack rail 20, which is an example of a rail, and a transporter 10 that can move along the rack rail 20. The transporter 10 loads the load WK at a first point as shown in Fig. 2, moves along the rack rail 20, and unloads the load WK at a second point as shown in Fig. 3. The transporter 10 includes a dolly 3, a towing vehicle 1 that tows the dolly 3, and a driver's car 2 on which a person rides. The driver's car 2 is for a driver who operates and drives the transporter 10. Although only one dolly 3 is shown in the examples of Figs. 1 and 4, a plurality of dollies may be connected by one towing vehicle. In addition, the transporter 10 may be configured such that the towing vehicle and the driver's car are integrated, or the driver's car and the dolly are integrated, or the towing vehicle and the dolly are integrated. Furthermore, the driver's car may be omitted and the towing vehicle may be remotely operated by wireless or wire. (Rack rail 20)

[0024] The rack rail 20 is provided with a rack 21 along the extension direction. The towing vehicle 1 is provided with a pinion that meshes with the rack 21, and can move back and forth on the rack rail 20 by rotation of the pinion. The combination of the rail and the rotating body that moves on this rail is not limited to the combination of a rack and a pinion. For example, a known configuration can be used as appropriate, such as a configuration in which holes provided at equal intervals in the rail mesh with protrusions provided around the rotating body to move on the rail, or a rack or the like is provided on the side of the rail. The towing vehicle 1 is equipped with a driving mechanism such as an engine or a motor that drives a pinion, and tows the bogie 3 and the driver's vehicle 2. (Support part 22)

[0025] Further, the rack rail 20 has support parts 22 fixed to its underside. By interposing the support parts 22 between the underside of the rack rail 20 and the installation surface of the ground on which the rack rail 20 is installed, the rack rail 20 is supported on the installation surface by the support parts 22. As shown in Figs. 1 to 4, a plurality of support parts 22 are fixed at a distance along the extension direction of the rack rail 20. (Cart 3)

[0026] The dolly 3 is equipped with a platform 4 for placing the load WK. A heavy object such as heavy machinery is placed on the platform 4 as the load WK, and is secured with a rope or the like as necessary. The platform 4 can also be provided with a support 5. The support 5 is formed by bending a metal rod, and can be used to prevent the load WK from slipping off. (Carried object WK)

[0027] An example of the load WK is a heavy machine as shown in FIG. 5. As shown in FIG. 6, the heavy machine is preferably a type that can be disassembled into certain parts PT1 and PT2. By disassembling into the parts PT1 and PT2, the bulk and weight to be transported can be reduced, making it easier to transport with a small transport device. When disassembling into the parts PT1 and PT2, it is more preferable to disassemble into a second part PT2 that can move on its own and a first part PT1 that is not a part of the load WK. If the second part PT2 is moveable on its own, it can be moved independently and placed on the mounting table 4.

[0028] Generally, it is difficult for a transport device to load and unload a heavy object such as heavy machinery onto the platform of a cart. In particular, the locations where the transport device is installed are generally mountainous areas or steep slopes where it is difficult for vehicles to enter, and it is often not possible to install heavy machinery or cranes to suspend heavy objects.

[0029] In addition, when placing the load on the platform of the dolly, the balance of the dolly must be taken into consideration. As an example, consider a case where a heavy load WK7 is placed on the platform 704 of the transport device 700 according to the comparative example shown in FIG. 7. In the single-rail transport device 700, the center part of the dolly 703 is supported by the rack rail 720 from the rear side, so that the platform 704 tilts and the load WK7 will slip off if the center of gravity is not taken into consideration when placing the load. In order to prevent this, the load WK7 needs to be placed on the center part of the platform 704, but it is not easy to place the heavy load in an appropriate position. In particular, as described above, it is difficult to prepare equipment such as a crane at the location where the transport device is installed, so the task of placing the heavy load in an appropriate position in an appropriate posture is extremely difficult.

[0030] In contrast, the transport device 100 according to this embodiment, as shown in the plan view of Fig. 8 and the cross-sectional view of Fig. 9, is provided with a gate unit 40 equipped with a crane unit 60, which is added to a part of the rack rail 20, thereby realizing a self-contained transport device that has the function of assisting the loading and unloading of heavy objects and enables work to be performed without the need for a separate heavy machine such as a crane. Specifically, a cross bar 32, a guide bar 35, and a gate unit 40 are provided on a part of the rack rail 20. (Crossbar 32)

[0031] The cross bar 32 is fixed in a position intersecting with the rack rail 20. The cross bar 32 is preferably fixed to a support portion 22 that supports the rack rail 20. As shown in FIG. 4, the cross bars 32 are fixed below the rack rail 20 in a position intersecting with the extension direction of the rack rail 20 in the horizontal direction so as to intersect with adjacent support portions 22, including the support portion 22 located at the end edge of the rack rail 20, in the vertical direction. In the example of FIG. 8, the cross bars 32 are fixed to three support portions 22a counting from the end edge of the rack rail 20, respectively, spaced apart from each other. Preferably, these three support portions 22a are configured to be lower in height than the other support portions 22, and the lower ends of the support portions 22a are inserted into the tube portions 33 provided in the center of each cross bar 32 for support. For this reason, each cross bar 32 has a tubular portion 33 on its central upper surface, into which the lower end of the cross bar 32 is inserted, and a cross leg portion 34 on its lower surface, which protrudes toward the installation surface. Each cross bar 32 extends to the left and right. The end edges of each cross bar 32 are aligned in a straight line parallel to the rack rail 20. The number of support portions 22a that cross the cross bar 32 is not limited to three, and may be four or more or two or less depending on the required strength. (Guide bar 35)

[0032] The guide bars 35 are fixed to the ends of the cross bars 32. In the examples of Figs. 8, 9, etc., a pair of guide bars 35 are fixed to the ends of the cross bars 32. Each guide bar 35 extends parallel to the rack rail 20. Also, a plurality of guide legs 38 are provided along the length of each guide bar 35 to fix the guide bars 35 on the installation surface. (Reinforcement bar 36)

[0033] A reinforcing bar 36 may also be disposed between the pair of guide bars 35. By intersecting and fixing the reinforcing bar 36 with the cross bar 32, the strength of the base portion of the gate section 40 can be further increased, and stability can be improved. In the example of Fig. 8 and Fig. 4, two reinforcing bars 36 are disposed between the guide bars 35 in a plan view. Preferably, a reinforcing bar 36 is disposed between the rack rail 20 and the guide bars 35 on either side of it in a plan view. (Gate 40)

[0034] The gate section 40 is slidably attached to the pair of guide bars 35. As shown in FIG. 9, the gate section 40 is formed in a U-shape when viewed from the front, and bridges the rack rail 20 above the rack rail 20 so as to intersect with it. The U-shaped gate section 40 is composed of a horizontal gate section 41 and a pair of vertical gate sections 42 extending from both sides of the horizontal gate section 41. The horizontal gate section 41 is preferably an H-beam. This makes it easy to attach the crane section 60. The vertical gate section 42 can be made of a metal pipe or the like. (Moving mechanism 50)

[0035] The gate unit 40 is configured to be movable along the extending direction of the rack rail 20. For this reason, the gate vertical part 42 of the gate unit 40 is provided with a moving mechanism 50 that slides along the guide bar 35 extending parallel to the rack rail 20. The moving mechanism 50 can appropriately use a known slidable mechanism such as a roller and a flat plate, a rail and a wheel, a rack and a pinion, or a concave and a convex. In the example of FIG. 4, as shown in the side view of FIG. 10 seen from the inside to the outside, a gate leg part 45 extending along the guide bar 35 is fixed to the lower end of the gate vertical part 42. The gate leg part 45 holds the upper and lower parts of the guide bar 35 formed in a square pipe shape with guide rollers 46, respectively. The gate leg part 45 slides on the guide bar 35 by the rotation of the guide rollers 46. This makes it possible to slide the gantry crane type gate part 40 along the guide bar 35. (Crane section 60)

[0036] A crane unit 60 that can move up and down is provided above the mounting platform 4. The upper end of the crane unit 60 is fixed to the center of the horizontal gate portion 41 of the gate unit 40 as shown in Fig. 4. An inexpensive and easy-to-use chain block or the like can be suitably used as the crane unit 60. The crane unit 60 may be movable left and right along the horizontal gate portion 41, in addition to being fixed to the center of the horizontal gate portion 41.

[0037] By providing such a gantry crane type crane unit 60 on a part of the rack rail 20, it becomes possible to load and unload the load WK using the crane unit 60. Even in places where it is difficult to bring in equipment to assist in the loading and unloading work, by incorporating the crane unit 60 into the track itself, it becomes possible to complete the loading and unloading work with the transport device alone, improving convenience.

[0038] As shown in Fig. 8, the area between the pair of guide bars 35 and beyond the edge of the rack rail 20, i.e., the area where the cross bar 32 is not provided, is a work area WS where the load WK is loaded and unloaded by the crane unit 60 described later. In the example of Fig. 8, the left side of the pair of guide bars 35 is open, and a truck, a loading platform, etc. can be brought into the work area WS from here. In this state, for example, as shown in Fig. 2, the load WK placed on a loading platform located in the work area WS can be moved to the loading platform 4 of the cart 3, or conversely, as shown in Fig. 3, the load WK placed on the loading platform 4 can be moved to the loading platform RK located in the work area WS.

[0039] In the example of the transport device 100 according to the first embodiment, the gate unit 40 is moved manually. However, the present disclosure is not limited to this configuration, and the gate unit may be moved automatically by a motor, an engine, or the like. (Outrigger 70)

[0040] Further, a removable outrigger 70 supported between the guide bar 35 may be added to the underside of the mounting platform 4. When loading and unloading the load WK7 onto and from the mounting platform 704 of the dolly 703 running on a single-rail type rack rail 720 as in the transport device 700 according to Comparative Example 1 shown in FIG. 7, weight balance must be considered. In particular, in the case of a heavy object such as a heavy machine, if the mounting platform 704 tilts, the load WK7 may slide off. Therefore, in the transport device 100 according to this embodiment, as shown in FIG. 9, the outrigger 70 is provided on the underside of the mounting platform 4 to prevent the mounting platform 4 from tilting. In particular, by arranging the outrigger 70 on the left and right sides of the direction intersecting the extension direction of the rack rail 20 (the width direction in FIG. 9), both ends of the underside of the mounting platform 4 are supported, and the mounting platform 4 can be stably held in a horizontal position when a heavy object is loaded and unloaded onto the upper surface of the mounting platform 4. More preferably, the outrigger 70 is preferably arranged at the four corners of the mounting platform 4 as shown in FIG. 4. This makes it possible to hold the mounting table 4 in a horizontal position more stably.

[0041] 4 and 9, the outrigger 70 is preferably supported by fixing its lower end to the upper surface of the reinforcing bar 36 so as to brace the space between the upper surface of the reinforcing bar 36 and the lower surface of the mounting table 4. This makes it possible to use the reinforcing bar 36, which reinforces the base of the gate section 40, as a support for the outrigger 70.

[0042] Furthermore, the outriggers 70 are installed before an operation of loading and unloading an object onto and from the mounting table 4. After the loading and unloading operation is completed, the outriggers 70 are removed to enable the mounting table 4 to move along the rack rails 20. (Stepping Board 80)

[0043] Furthermore, as shown in FIG. 11, a running board 80 for making it easier to place the self-propelled load WK on the platform 4 may be attached to the platform 4. The running board 80 can be connected to the edge of the platform 4. As shown in FIG. 12 (illustration of a gate and the like is omitted for the sake of explanation), when the running board 80 is connected to the edge, a downwardly sloping surface can be formed from the edge to the installation surface. This allows the second part PT2, which can run on wheels such as crawlers, to be smoothly loaded and unloaded onto the platform 4. In particular, when a heavy machine equipped with a crawler unit as shown in FIG. 5 and FIG. 6 is transported by the transport device 100, the self-propelled crawler can be self-propelled to load and unload the machine onto and from the platform 4.

[0044] Such a running board 80 is preferably detachably attached to the mounting table 4. For example, as shown in Fig. 4 etc., in a configuration in which a support 5 is provided at the rear end of the mounting table 4, the support 5 is detachable. In the example shown in Fig. 13, the support 5 can be removed by releasing the screw engagement at the lower end of the support 5. (Plate connection part 82)

[0045] Also, a plate connecting part 82 may be added so that the running board 80 can be connected to the rear end of the mounting base 4. In the example shown in FIG. 14, the plate connecting part 82 is fixed to the rear end of the mounting base 4 from which the support 5 has been removed. This makes it possible to attach the running board 80 to the plate connecting part 82. In the example shown in FIG. 15, the plate connecting part 82 has a pocket part 83 formed at the rear end. Meanwhile, the running board 80 has a locking piece 81 at the end on the side that is connected to the mounting base 4. The locking piece 81 of the running board 80 can be inserted into the pocket part 32 of the plate connecting part 82 to connect the running board 80 to the mounting base 4. Also, two running boards 80 are attached to the plate connecting parts 82, respectively, depending on the width of the crawler to be placed on the mounting base 4. The width of the running board 80 can be selected depending on the width of the crawler. (Switchback)

[0046] The above-mentioned gantry crane type gate unit 40 is provided at a position where the load WK is to be loaded and unloaded, such as at both ends or at an intermediate position of the rack rail 20, as shown in FIG. 1 and the like. In this case, if the carriage 3 is positioned at the edge side of the rack rail 20 as shown in FIG. 2 or FIG. 4, the loading platform 4 and the working area WS are adjacent to each other, so that the load WK can be loaded and unloaded relatively easily. On the other hand, if the towing vehicle 1 is positioned at the end side of the rack rail 20 as shown in FIG. 3, the load WK needs to be moved from the loading platform 4 to the working area WS over the towing vehicle 1 and the driver's vehicle 2 in this state, and the distance to move the load WK becomes long. In addition, when the gate unit 40 is positioned at the intermediate position of the rack rail 20, securing a space for loading and unloading the load WK is also an issue.

[0047] For this, a method called a switchback or the like can be used for moving trains. That is, by branching the rack rail 20 to the branch line 20B and providing a gate unit 40 at the end of the branch line 20B, it becomes possible to orient the transporter 10 to the position shown in FIG. 4, that is, the position in which the bogie 3 is located on the edge side of the branch line 20B of the rack rail 20. In order to pull the transporter 10 into the branch line 20B, in addition to using a switch for the rack rail 20, a method of using a curved rack rail 20 by replacing it as shown in FIG. 16 can be used. Here, the main line 20A and the branch line 20B of the rack rail 20 are laid diagonally in advance, and the connecting rack rail 20X at the portion connecting the rack rail 20 and the main line 20A is curved. When pulling the transporter 10 from the main line 20A into the branch line 20B, the transporter 10 is once passed through the connecting rack rail 20X, and then the connecting rack rail 20X is removed and set in the opposite direction as shown by the dashed line. Then, by moving the transporter 10 backward, the transporter 10 can be guided to the branch line 20B. When moving from the branch line 20B to the main line 20A, the procedure is reversed, making it possible to easily move the transporter 10 to the main line 20A side. With this method, it is possible to easily change the relative position between the edge of the rack rail 20 and the bogie 3. Also, the attitude of the transporter 10 can be changed at any position, such as the starting position, the terminal position, or an intermediate position.

[0048] Furthermore, even if the switchback section as described above is not provided, a space for loading and unloading the load may be secured by, for example, partially lifting up or temporarily removing a part of the rack rail. After the loading and unloading of the load is completed, the rack rail can be returned to its original position, allowing the transport machine to move along the rack rail.

[0049] In the above example, a configuration in which a gate unit 40 having a gantry crane type crane unit 60 is provided at the end of the rack rail 20 has been described. Specifically, the cross bar 32 is fixed using the support unit 22 that supports the rack rail 20, and a crane unit such as the gate unit 40 is added. However, in the present disclosure, it is not necessary to physically fix the gate unit to the rack rail, and it is possible to assist the loading and unloading of the load on the cart on the rack rail by aligning it relative to the rack rail in some way. For example, the gate unit may be configured as a separate unit, and may be assembled and installed at the site where the load is loaded and unloaded, such as the end or intermediate position of the rack rail. By disassembling the unit type gate unit, it is possible to make it large enough to be transported by a transport machine, and relatively lightweight, so that it can be loaded and unloaded by hand. In addition, when loading and unloading, outriggers can be added between the four corners of the loading platform and the installation surface as necessary. Furthermore, the installation position is determined by visually aligning the gate unit so that it straddles the center of the rack rail. In this way, the transport work of the gate section itself is performed by a transport machine, and by adding the gate section, a transport device can be realized in which even heavy objects that are difficult to load and unload manually can be loaded and unloaded using the gate section. In this way, the present disclosure does not necessarily require a physical connection between the rack rail and the gate section, etc., and by visually aligning the rack rail and the cart moving on it, the correlation between the gate section and the rack rail, the cart, etc. is maintained, making it possible to load and unload the load onto the loading platform. In the present disclosure, providing a member such as a gate section on a part of the rack rail does not necessarily require a physical connection state, and even if these are present separately, it is sufficient that they are arranged in a relative position that allows the load to be loaded and unloaded onto the loading platform by the crane section of the gate section, and such a state in which they are installed separately from each other is also included in the meaning of "provided on a part of the rack rail". [Embodiment 2]

[0050] As an example, FIG. 17 shows a transport device 200 according to a second embodiment in which the crane part is a unit type. In this figure, the same members as those in the first embodiment are given the same reference numerals and detailed description is omitted as appropriate. The transport device 200 shown in this figure has a crane unit 40B, which is a separate member, at the end of the rack rail 20. The crane unit 40B is transported by the conveyor 10 to a place where the crane unit 40B is to be installed in a disassembled state into its constituent members. The crane unit 40B is then assembled on-site and installed in a position where the crane unit 60 can load and unload the load WK on the platform 4. At this time, the crane unit 40B may be assembled in advance at a stage of assembling the crane unit 40B so that the crane unit 60 can load and unload the load WK on the platform 4, or a moving mechanism 50B capable of moving the crane unit 40B may be provided, and the crane unit 40B may be moved to a position where the crane unit 60 can load and unload the load WK on the platform 4 after the crane unit 40B is assembled. When the crane unit 40B is provided with a moving mechanism 50B capable of moving itself, the gate leg portion provided with the sliding mechanism described in the transport device according to the first embodiment can be omitted. In the example shown in FIG. 17, casters are added to the four corners of the crane unit 40B as the moving mechanism 50B. This allows the crane unit 40B to be pushed manually to a desired position. After moving to a desired position by the moving mechanism 50B such as casters, the crane unit 40B is fixed with a jack or the like so that it does not move. By configuring the crane unit 40B as a separate body from the rack rail 20 in this way, it becomes possible to reuse the crane unit 40B at other work sites, etc.

[0051] In addition, when assembling the crane unit 40B separately from the rack rail 20, it is necessary to ensure the strength of the crane unit 40B itself. That is, in the transport device 100 according to the first embodiment, the cross bar 32 and the guide bar 35 are fixed using the support part 22 that supports the rack rail 20 as shown in FIG. 4 and the like, so that it is possible to maintain a certain degree of strength. On the other hand, in the transport device 200 according to the second embodiment, the support part 22 and the like cannot be used to make the rack unit stand independently. In particular, a configuration is required to maintain the pair of guide bars 35 parallel at a constant interval so that the gate part 40 can move along the guide bar 35. Therefore, in the example of FIG. 17, the cross bar 32 is fixed to the tip of the pair of guide bars 35 on the side facing the mounting table 4, while the opening cross bar 32X is also provided on the rear end side of the guide bar 35. This makes it easier to maintain the interval between the pair of guide bars 35 in a parallel state. On the other hand, if the rear end side of the pair of guide bars 35 is blocked by the opening cross bar 32X, it becomes difficult to move a pedestal or the like to the working area WS of the crane unit 60. Therefore, it is preferable that the opening cross bar 32X is detachable. For example, after assembling the crane unit 40B, the crane unit 60 moves it to a position where the load WK on the platform 4 can be loaded and unloaded. Then, the crane unit 40B is fixed at this position with a jack or the like, and then the opening cross bar 32X is removed to open the rear end side of the pair of guide bars 35, making it easier to guide a truck or a pedestal for loading and unloading the load WK to the working area WS of the crane unit 60.

[0052] In the above example, a single-rail rack rail is used as the rail 20, but the present disclosure is not limited to rack rails, and any known rail can be used as appropriate. In the above example, a crane portion is added to a single rail, but it goes without saying that a crane portion can also be added to a multiple rail. [How to move the load]

[0053] Next, a method for moving the load WK using the transport device 100, which moves the load WK from the first point LO1 shown in Fig. 1 to the second point LO2 by the transport machine 10 along the single-rail rack rail 20, will be described. First, the load WK is disassembled into a first part PT1 and a second part PT2. Next, the first part PT1 is lifted up and placed on the mounting table 4 using a first crane unit 60 which is fixed to the ends of a pair of first guide bars 35 extending parallel to the rack rail 20 and which is fixed to a part of the rack rail 20 at the first point LO1 so as to intersect with the rack rail 20 (here, this will be referred to as the "first cross bar" in order to distinguish between the cross bar provided at the first point LO1 and the cross bar provided at the second point LO2. Similarly, other parts will be distinguished hereinafter according to whether they are provided at the first point LO1 or the second point LO2). The first crane unit 60 is fixed to the ends of a pair of first guide bars 35 extending parallel to the rack rail 20 and is provided on a first gate unit 40 which bridges the rack rail 20 above the rack rail 20 so as to intersect with the rack rail 20. The first crane unit 60 can be moved up and down above the mounting table 4.

[0054] Furthermore, the placement table 4 on which the first part PT1 is placed is moved by the transporter 10 from the first point LO1 to the second point LO2.

[0055] Then, the first part PT1 is lifted up and lowered from the mounting table 4 using a second crane unit 60 which is movably attached to a pair of second guide bars 35 which are fixed to a part of the rack rail 20 at the second point LO2 so as to intersect with the rack rail 20, and which are respectively fixed to the ends of the opening cross bars 32X extending to the left and right of the rack rail 20 and extend parallel to the rack rail 20, and which is provided on a second gate unit 40 which bridges the rack rail 20 above and intersects with the rack rail 20.

[0056] The transporter 10 is again moved from the second point LO2 to the first point LO1. Similarly, the second part PT2 is moved from the first point LO1 to the second point LO2 by the transporter 10. Then, at the second point LO2, the first part PT1 and the second part PT2 are assembled. In this manner, by providing a gantry crane type crane on a part of the rack rail 20, it becomes possible to use the crane to load and unload the load WK. Even in places where it is difficult to bring in equipment to assist the loading and unloading work, such as mountainous areas, by incorporating a crane into the transport device itself, it becomes possible to complete the loading and unloading work with the transport device alone, improving convenience. Note that, if the second part PT2 is self-propelled, it can be loaded and unloaded onto the platform 4 using the above-mentioned running board 80 or the like without using the crane unit.

[0057] It goes without saying that the gate unit 40 and the crane unit 60 can be disassembled and transported by the transport machine 10. The members that make up the gate unit 40 and the crane unit 60 are relatively light, and can be loaded and unloaded by hand without using a crane or the like. Furthermore, the gate unit 40 and the crane unit 60 that have been disassembled and transported by the transport machine 10 can be assembled at the site where they are to be unloaded.

[0058] Furthermore, in the above-mentioned method for moving the loaded object, an example has been described in which the gate unit 40 and the crane unit 60 are installed at the first point LO1 and the second point LO2 where the loaded object is loaded and unloaded, respectively. However, the present disclosure is not limited to a configuration in which multiple sets of such gate units and crane units are prepared, and depending on the type of the loaded object, it is also possible to prepare only one set of gate units and crane units for transportation and loading and unloading.

[0059] For example, in the case of the object shown in FIG. 6, in a state where the object is disassembled into a second part PT2 capable of self-propelling and a plurality of other first parts PT1, the plurality of first parts PT1 can be loaded on the platform 4 at one time, and there is also room for the gate unit 40 and the crane unit 60 to be placed on the platform 4. In this case, the first part PT1 (e.g., a long and large part such as a boom part of a crane) that cannot be placed on the platform 4 without first using the gate unit 40 and the crane unit 60 is placed on the platform 4. Thereafter, the gate unit 40 and the crane unit 60 are disassembled and similarly placed on the platform 4. In addition, other first parts PT1 that can be placed manually are similarly placed on the platform 4. The order of these manually loadable members does not matter as long as they are placed after the loading operation using the gate unit 40 and the crane unit 60 is completed.

[0060] Then, when loading at the first point LO1 is completed, the transporter 10 moves it to the second point LO2. When it moves to the second point LO2, the members that can be loaded and unloaded manually, including the components of the gate unit 40 and the crane unit 60, are removed from the platform 4. Then, at the second point LO2, the gate unit 40 and the crane unit 60 are assembled and installed. This makes it possible to use the gate unit 40 and the crane unit 60 to lower the first part PT1.

[0061] As described above, the self-propelled second part PT2 can be loaded onto and unloaded from the platform 4 using the running board 80 or the like without using the crane unit, and can therefore be transported by the transporter 10 separately from the first part PT1. The second part PT2 may be transported before the first part PT1, or after the first part PT1. When assembling the first part PT1 and the second part PT2, the crane unit 60 can also be used as necessary. For example, the long and large first part PT1 can be lifted by the crane unit 60 and positioned above the second part PT2.

[0062] On the other hand, even if the first part PT1, which cannot be placed on the platform 4 without using the gate unit 40 and the crane unit 60, cannot be transported by the transport machine 10 at once, it is possible to transport the gate unit 40 and the crane unit 60 as a single set by repeating the transport, assembly, and disassembly of the gate unit 40 and the crane unit 60. That is, the first first part PT1 is temporarily moved from the first point LO1 to the second point LO2 by the above-mentioned method, and after being taken off the platform 4, the gate unit 40 and the crane unit 60 are disassembled at the second point LO2, placed on the platform 4, and moved to the first point LO1 by the transport machine 10. Then, the gate unit 40 and the crane unit 60 are assembled again at the first point LO1, and the second second part PT2 is placed on the platform 4 with the assembled crane unit 60. Thereafter, the gate unit 40 and the crane unit 60 are disassembled and placed on the platform 4, and similarly transported from the first point LO1 to the second point LO2. At the second location LO2, the gate unit 40 and the crane unit 60 are similarly assembled, and the second first part PT1 is lowered.

[0063] Similarly, the gate unit 40 and the crane unit 60 are disassembled again at the second point LO2 and returned to the first point LO1 by the transporter 10, and the third and subsequent first parts PT1 are moved. Although this method requires repeated disassembly and assembly of the gate unit 40 and the crane unit 60, it becomes possible to transport heavy objects or long parts that cannot be transported in one go with only one set of the gate unit 40 and the crane unit 60. In this case, the first and second gate units, the first and second crane units, the first and second cross bars, the first and second guide bars, and the like, which are described in the above-mentioned method for moving a loaded object, can be common members. [Industrial Applicability]
