[Technical Field]

[0001] The present invention relates to a material and equipment transport system, and more particularly to a material and equipment transport system for transporting materials and equipment to the upper level of a temporary scaffold. [Background technology]

[0002] Conventionally, when transporting materials and equipment from a materials storage area to a designated position on the upper level of the scaffolding during construction work using temporary scaffolding, the materials and equipment would be transported, for example, by a cart from the materials storage area to near the lower level of the scaffolding (see, for example, cited reference 1), then transferred to a lifting device, and transported from the lower level to the upper level of the scaffolding by the lifting device (see, for example, cited reference 2), and then transferred to a cart prepared on the upper level of the scaffolding or transported by hand to the designated position, such as the work position on the scaffolding (see, for example, cited reference 3).

[0004] However, as shown in Patent Documents 1 to 3 above, transferring and shifting materials and equipment at each location causes problems, such as the work becoming complicated and time-consuming, resulting in poor work efficiency, and also making such work more prone to errors.

[0005] The present invention has been made in consideration of such problems, and aims to provide an equipment and materials transport system that can transport equipment and materials from an equipment and materials storage area to a designated position on the upper level of scaffolding without having to transfer them, thereby improving work efficiency and work safety. [Means for solving the problem]

[0006] In order to achieve this objective, the present invention provides an equipment and materials transport system for transporting materials and equipment to a predetermined position on the upper level of a scaffolding having a multiple-level configuration, the system comprising: a cart for loading the materials and equipment; a lifting means for moving the cart with the materials and equipment loaded from the lower level to the upper level of the scaffolding; and a rail for connecting a connecting member provided on the cart that has been moved from the lifting means to the upper level of the scaffolding and guiding it to the predetermined position, the system being configured to transport the materials and equipment while still loaded on the cart from the lower level to the predetermined position on the upper level of the scaffolding.

[0007] Furthermore, in addition to the configuration described above, the present invention is characterized in that the connecting member of the trolley is configured to surround the rail, and the rail arranged on one side of the scaffolding is inserted into the connecting member, thereby connecting the trolley so that it can move along the rail.

[0008] Furthermore, in addition to the configuration described above, the present invention provides an equipment and materials transport system in which the rails include a straight rail arranged in a straight portion of the scaffolding, an outer curved rail arranged in an outer curved portion where the rail is located on the outside of the curve, and an inner curved rail arranged in an inner curved portion where the rail is located on the inside of the curve, and the inner curved rail is a rod-shaped member rotatably supported on the scaffolding, with both ends each being attachable to and detachable from the ends of the other rails, and the connecting member of the cart is moved from the other rail connected to one end of the inner curved rail to the inner curved rail, the one end of the inner curved rail is detached from the other rail, the inner curved rail is rotated, the other end of the inner curved rail is attached to the other rail on the opposite side, and the connecting member is moved to the other rail on the opposite side, thereby rotating and moving the cart on the inner curved portion.

[0009] Furthermore, in addition to the configuration described above, the present invention is characterized in that the trolley has a main body on which the materials and equipment are placed, a moving means for moving the main body, and the connecting member, and the moving means has auxiliary moving means that can be converted between a stored state in which it is stored within the width of the main body and an expanded state in which it is expanded wider than the width of the main body, and is an equipment and materials transport system configured so that when moving in a wide space, the auxiliary moving means is in the expanded state to maintain a stable moving state, and when moving in a narrow space or when supported by the rail, the auxiliary moving means is in the stored state to enable movement while avoiding obstacles.

[0010] Furthermore, in addition to the configuration described above, the present invention is characterized in that the trolley has a main body on which the materials and equipment are placed, a moving means for moving the main body, and the connecting member, and the main body is formed so that scaffolding boards can be placed on it so that their longitudinal direction is at an oblique angle relative to the vertical, making the height lower.

[0011] In addition to the above-described configuration, the present invention is characterized in that the equipment and materials transportation system is configured so that at least a portion of the rails can also be used as frame members that make up the scaffolding.

[0012] Furthermore, in addition to the configuration described above, the present invention is characterized in that the connecting member of the trolley is connected to the rail so that the support point is at a higher position than when the trolley is in a standalone state, thereby making the tipping angle of the trolley larger than when it is in a standalone state and stabilizing the travel of the trolley when it moves along the rail. [Effects of the Invention]

[0013] According to the present invention, a cart loaded with materials and equipment can be moved from the materials storage area to a designated position on the upper level of the scaffolding, so that the materials and equipment can be transported from the materials storage area to a designated position on the upper level of the scaffolding without having to be transferred, thereby improving work efficiency and work safety.

[0014] Furthermore, according to the present invention, the connecting member is configured in a shape that surrounds the rail, and the trolley can be moved along the rail simply by inserting the rail into the connecting member, so that the trolley can be moved safely on the scaffolding with a simple configuration.

[0015] Furthermore, according to the present invention, when moving the carriage safely and smoothly, it becomes easy to handle the carriage on the inner curved section, and the carriage can be moved to the predetermined position simply and reliably.

[0016] Furthermore, according to the present invention, the trolley has an auxiliary movement means that can be converted between a stored state and an extended state, so that the state of the auxiliary movement means of the trolley can be converted depending on the conditions of the location to which the trolley is being moved, allowing the trolley to be moved to a predetermined position in a more stable and easier-to-handle state.

[0017] Furthermore, according to the present invention, the main body of the cart is formed so that materials and equipment can be placed at an oblique angle, so that even if a long scaffolding board is placed on the cart, the cart can be moved smoothly without any problems such as the scaffolding board hitting the ceiling due to the height of the scaffolding.

[0018] Furthermore, according to the present invention, by using the rails as framework members that make up the scaffolding, the number of parts in the scaffolding can be reduced, and the work efficiency of setting up the scaffolding can be improved.

[0019] Furthermore, according to the present invention, when the bogie is connected to the rail, the support point of the bogie is at a higher position, and the support interval of the bogie is between the running wheels and the rail, which increases the tipping angle and stabilizes the bogie guidance. Furthermore, the support interval of the bogie can be changed with a simple configuration between the standalone state and when connected to the rail. [Brief explanation of the drawings]

[0021] Hereinafter, an embodiment of the present invention will be described.

[0022] 1 to 16 show an embodiment of the present invention.

[0023] The equipment and materials transport system of this embodiment is a system that uses scaffolding 1 to be installed at a construction site such as a construction site, repair work site, or inspection work site, and transports equipment used to assemble the scaffolding 1, equipment used for construction work, and materials used for construction work, etc., from a designated equipment and materials storage area on the ground, etc. to a designated position, such as a work position on the upper level of the scaffolding 1, while still loaded on a cart 20 and without having to be transferred.

[0024] As shown in Figure 1, the scaffolding 1 of this embodiment has multiple stages, including at least two stages, an upper stage 1A and a lower stage 1B, and the equipment and material transport system of this embodiment is configured to transport equipment and materials Z (here, scaffolding boards 10 are shown) from a predetermined position on the lower stage 1B (for example, an equipment and material storage area not shown) to a predetermined position on the upper stage 1A.

[0025] This equipment and material transport system is configured to include a cart 20 on which equipment and material Z is placed, a lifting device (gondola, elevator, etc.) 30 as a lifting means for moving the cart 20 loaded with equipment and material Z from the lower section 1B of the scaffolding 1 to the upper section 1A, and a rail 40 that connects a connecting member 24 provided on the cart 20 moved from the lifting device 30 to the upper section 1A of the scaffolding 1 and guides it to a predetermined position, and is configured to transport the equipment and material Z while it is still loaded on the cart 20 from outside the scaffolding 1 (such as an equipment and material storage area) via the lifting device 30 to a predetermined position on the upper section 1A of the scaffolding 1.

[0026] Each component will be described in detail below with reference to the drawings.

[0027] First, a scaffolding 1 will be described with reference to Figure 1. The scaffolding 1 of this embodiment is constructed by arranging scaffolding boards 10 on three-dimensionally assembled frame members 5 (here, other members such as pipe materials can also be used), and is formed into multiple stages (here, two stages: upper stage 1A and lower stage 1B). It also has a stair section 6 for movement, and is further provided with an elevating device 30 as an elevating means. The scaffolding boards 10 of this embodiment are configured to be hooked onto the frame members 5 of the scaffolding 1 by hooks (not shown) and held in place.

[0028] Next, the dolly 20 will be described with reference to Figures 2 to 16. The dolly 20 of this embodiment has a main body 21 on which the equipment and materials Z are placed, running wheels 22 as a moving means, outriggers 23 as an auxiliary moving means, and connecting members 24 for attaching the dolly 20 to the rails 40 of the scaffolding 1.

[0029] Of these, the main body 21 has a bottom surface 25, which is disposed at a predetermined angle, so that when the scaffolding board 10 is placed on it, the scaffolding board 10 is held at an angle, allowing the scaffolding board 10 to be kept at a low height. It also has a mid-bottom 26, which is used when transporting small components other than the scaffolding board 10. As shown in Figures 3 and 4, this mid-bottom 26 can be stored toward the back board, allowing long components such as the scaffolding board 10 to be placed on the main body 21. The sides also have a side pivoting section 27 and a side opening / closing section 28, which can be pivoted and opened / closed to open the sides widely, facilitating the loading and unloading of the scaffolding board 10, etc.

[0030] Four running wheels 22 are arranged at the front and rear, allowing for stable running. The outriggers 23 are rotatable and can be freely changed between a stored state as shown in Figures 8 and 9 and an extended state as shown in Figures 2 and 3. This allows the outriggers 23 to be extended and maintained in a stable state in wide spaces such as outside the scaffolding 1, and the outriggers 23 to be stored in narrow spaces such as on the scaffolding 1, allowing running in narrow places.

[0031] Furthermore, the connecting member 24 of this embodiment is configured in a shape that surrounds the rail 40, as shown in Figure 6 (including a ring-shaped, C-shaped, U-shaped, square-shaped, etc. In addition to a shape that completely surrounds the rail, it may also be a shape that partially surrounds the rail, as shown in Figure 6).

[0032] Here, the connecting member 24 sandwiches and holds the rail 40 between two upper first receiving portions 24a and two lower second receiving portions 24b, and in this state, the carriage 20 is moved along the rail 40 while holding the rail 40. In this embodiment, the connecting member 24 is formed at two locations with a predetermined distance between them, thereby enabling the connecting member 24 to be stably held on the rail 40. Note that the connecting member 24 is not limited to the shape described above. For example, as in the case of connecting member 124 shown in FIG. 7, the rail 40 may be supported by two upper first receiving portions 124a and two lower second receiving portions 124b attached via a linear member, or the connecting member 24 may have another shape (any appropriate shape may be used as long as it can stably hold the rail 40).

[0033] In this embodiment, the center of gravity of the bogie 20 is G1 when unladen and G2 when loaded. In either state, the center of gravity is high, resulting in an unstable state. In contrast, when the bogie 20 is in a standalone state, the support interval is between the running wheels 22 and the extended left and right outriggers 23, resulting in a small tipping angle and a higher center of gravity than the support point. When the connecting member 24 is connected to the rail 40, the support interval is between the running wheels 22 and the rail 40, widening the support interval and increasing the tipping angle, resulting in the support point of the bogie 20 (the connection point between the connecting member 24 and the rail 40) being higher than the center of gravity. This allows the bogie 20 to be stably supported by the running wheels 22 and the connecting member 24 connected to the rail 40. As a result, the bogie 20 is configured to travel stably when moving along the rail 40.

[0034] 9 and 10, the cart 20 is configured so that, when it is lowered from the lifting device 30 to the position of the upper section 1A, the mounting rail 40D of the rail 40 arranged on one side of the scaffolding 1 is inserted into the connecting member 24, and the cart 20 is connected so as to be able to move along the rail 40. Here, the mounting rail 40D is gradually inclined upward toward the straight rail 40A, which causes the connecting member 24 to be gradually pulled upward, and as a result, the support point of the cart 20 (the connection position between the connecting member 24 and the rail 40) is configured to move to a position higher than the center of gravity.

[0035] The rails 40 include a straight rail 40A arranged in the straight section 2 of the scaffolding 1, an outer curved rail 40B arranged in the outer curved section 3 where the rail 40 is located on the outside of the curve, and an inner curved rail 40C arranged in the inner curved section 4 where the rail 40 is located on the inside of the curve. Of these, the inner curved rail 40C is a straight rod-like member rotatably supported on the scaffolding 1 by an axis 43C as shown in Figures 13 and 14, and has extensible members 42C on both ends thereof as shown in Figure 15, each of which is attachable to and detachable from the end of another rail 40 (the straight rail 40A in this case).

[0036] 13 and 14, the connecting member 24 of the bogie 20 is moved from the other rail 40A connected to one end of the inner curved rail 40C to the inner curved rail 40C, one end of the inner curved rail 40C is detached from the other rail 40A, the inner curved rail 40C is rotated, the other end of the inner curved rail 40C is attached to the other rail 40A on the opposite side, and the connecting member 24 is moved to the other rail 40A on the opposite side, thereby rotating the bogie 20 on the inner curved section 4. At this time, when the connecting member 24 is connected to the inner curved rail 40C as shown in FIG. 16, a locking member such as a pin (not shown) from the connecting member 24 may be locked into an locked portion such as a hole (not shown) in the inner curved rail 40C, so as to prevent the bogie 20 from moving unexpectedly.

[0037] In this embodiment, the straight rail 40A constituting the straight section 2 of the rail 40 also serves as a frame member 5, and is configured so that the straight rail 40A also serves as the frame member 5. Note that in the outer curved section 3 and the inner curved section 4 other than the straight section 2, the rails 40B and 40C may also be configured to serve as the frame member 5 in some cases.

[0038] As described above, according to this embodiment, the cart 20 carrying the equipment and materials Z can be moved from the equipment and materials storage area to a predetermined position on the upper section 1A of the scaffolding 1, so that the equipment and materials Z can be transported from the equipment and materials storage area to a predetermined position on the upper section 1A of the scaffolding 1 without having to be transferred, thereby improving work efficiency and work safety.

[0039] Furthermore, according to this embodiment, the connecting member 24 is configured in a shape that surrounds the rail, and the trolley 20 can be moved along the rail 40 simply by inserting the rail 40 into the connecting member 24, so that the trolley 20 can be moved safely on the scaffolding 1 with a simple configuration.

[0040] Furthermore, according to this embodiment, in order to move the carriage 20 safely and smoothly, it is easy to handle the carriage 20 on the inner curved section 4, and the carriage 20 can be moved to a predetermined position simply and reliably.

[0041] Furthermore, according to this embodiment, the trolley 20 has outriggers 23 as auxiliary moving means that can be converted between a stored state and an extended state, so that the state of the outriggers 23 of the trolley 20 can be converted depending on the conditions of the location to which the trolley 20 is being moved, allowing the trolley 20 to be moved to a predetermined position in a more stable state with easier handling.

[0042] Furthermore, according to this embodiment, the main body 21 of the cart 20 is formed so that the equipment Z (here, the scaffolding board 10) can be placed at an oblique angle, so that even if a long scaffolding board 10 is placed on the cart 20, the cart 20 can be moved smoothly without any problems such as the scaffolding board 10 hitting the ceiling due to the height of the scaffolding 1.

[0043] Furthermore, according to this embodiment, by using the rails 40 as the framework members 5 that make up the scaffolding 1, the number of parts in the scaffolding 1 can be reduced, and the work efficiency of setting up the scaffolding 1 can be improved.

[0044] Furthermore, according to this embodiment, when the bogie 20 is connected to the rail 40, the support point of the bogie 20 is at a higher position, and the support interval of the bogie 20 is between the running wheels 22 and the rail 40, which increases the tipping angle and stabilizes the guidance of the bogie. Furthermore, the support interval of the bogie 20 can be changed with a simple configuration between the standalone state and when connected to the rail.

[0045] The present invention is not limited to the above-described embodiments, but can also be applied to other configurations and other usage situations.

[0046] For example, in the above-described embodiment, the scaffolding 1 has been described as having a two-tier structure consisting of an upper tier 1A and a lower tier 1B, but this is not limited to this and may also be applied to scaffolding having three or more tiers, and may be designed to be used when transporting equipment and materials Z from the lower tier to a predetermined position in the upper or middle tier.

[0047] Furthermore, as for the cart 20, it is preferable that it is configured so that the scaffolding board 10 can be placed at an angle, as in the embodiment described above, but this is not limited to this, and if space allows, it may be a cart configured so that the scaffolding board 10 can be placed in a straight vertical direction, or it may be a cart for transporting things other than scaffolding boards, and be configured to transport equipment and materials Z.
