[0009] Hereinafter, an embodiment will be described with reference to the drawings. The drawings are schematic or conceptual, and the relationship between the thickness and width of each part, the size ratio between parts, etc. are not necessarily the same as in reality. Even when the same part is shown, the dimensions and ratios of each part may be different depending on the drawing. In this specification and each drawing, elements similar to those described above with reference to the previous drawings are given the same reference numerals and detailed descriptions thereof will be omitted as appropriate.

[0010] FIG. 1 is a schematic plan view illustrating a weight transport device according to an embodiment. FIG. 2 is a schematic side view illustrating the weight transport device according to the embodiment. FIG. 3 is a schematic front view illustrating the weight transport device according to the embodiment. As shown in Figs. 1 to 3, the heavy object transport device 1 includes a plurality of height adjustment pipes 8, a lower slide 11, an upper slide 10, and a plurality of hydraulic pumps 7. The plurality of height adjustment pipes 8 are installed on a transport path along which an object 20 is transported. The lower slide 11 is provided on the plurality of height adjustment pipes 8. The upper slide 10 is provided on the lower slide 11. The upper slide 10 is provided so as to slide from the lower slide 11 via a slide operation mechanism 13 provided between the upper slide 10 and the lower slide 11.

[0011] In the specific example of FIG. 1 to FIG. 3, six height adjustment pipes 8 are provided, and the six height adjustment pipes 8 are provided at six locations on the rectangular frame-shaped lower slide 11 in plan view. The height adjustment pipes 8 are arranged at the four corners of the rectangular frame-shaped lower slide, and are also arranged at two locations, one at each location near the center of the two frames on the longer sides of the rectangular frame. The height adjustment pipes (supports) 8 can be adjusted in length in the vertical direction. The arrangement of the height adjustment pipes 8 in plan view is not limited to this example, and is appropriately set according to the longitudinal lengths of the upper slide 10 and the lower slide 11, the weight of the transported object 20 placed on the upper slide 10, and the like. The height adjustment pipes 8 can be any support, not just pipes, as long as they have sufficient strength and can be adjusted in height.

[0012] The lower slide 11 is a rectangular frame-shaped member in a plan view. For example, the rectangular frame is a rectangle having a long side and a short side. The lower slide 11 is configured by combining, for example, H-shaped steel members so as to have sufficient strength when the transported object 20 is placed via the upper slide 10. In order to have sufficient strength, reinforcing materials in the form of diagonal braces may be provided.

[0013] The upper slide 10 is provided on the lower slide 11. The upper slide 10 is a rectangular frame-shaped member in a plan view, similar to the lower slide 11. In terms of the frame portion, the upper slide 10 and the lower slide 11 can have the same configuration.

[0014] A hydraulic pump (lifting process driving means) 7 is provided on each of the six height adjustment pipes 8. The height of each of the six height adjustment pipes 8 can be adjusted up and down by the hydraulic pump 7, and can be fixed at a desired height. Note that, as long as it can support the upper slide 10, the lower slide 11, and the height adjustment pipes 8 on which the transported object 20 is placed, and can adjust the height of the height adjustment pipes 8, any other appropriate lifting and lowering driving means can be used, not limited to a hydraulic pump.

[0015] The upper slide 10 is provided on the lower slide 11 via a slide operation mechanism 13. The slide operation mechanism 13 is provided between the upper slide 10 and the lower slide 11. The upper slide 10 can slide in either direction in the longitudinal direction by the slide operation mechanism 13. The slide operation mechanism 13 is composed of, for example, a plurality of rollers (not shown) arranged along the longitudinal direction of the rectangular frame-shaped lower slide 11 within the frame.

[0016] The rollers can rotate around a rotation axis arranged perpendicular to the longitudinal direction. The rollers are connected by, for example, a chain or the like and driven by a motor (not shown). This allows the upper slide 10 on the rollers to slide in the longitudinal direction. The slide operation mechanism 13 is not limited to the above and can have any appropriate configuration as long as it can slide the upper slide 10 relative to the lower slide 11 in the longitudinal direction.

[0017] The upper slide 10 is provided with a plurality of moving rollers 4 having a rotation axis perpendicular to the longitudinal frame. Each of the plurality of moving rollers 4 is connected to a pulley 6, for example, within the longitudinal frame, and the pulley 6 is connected to a driving motor 2 by a roller driving chain 5. By driving the driving motor 2, the plurality of moving rollers 4 can convey an object 20 placed on the upper portion in either longitudinal direction via the roller driving chain 5 and the pulley 6.

[0018] An installation position mark 3 is provided on the frame on the short side of the upper slide 10. The installation position mark 3 allows the installation position of the transported object 20 to be easily set by setting the slide position of the upper slide 10 so that the installation position of the transported object 20 coincides with the installation position mark 3.

[0019] The upper slide 10 is provided with telescopic column storage sections 9 on both sides in the longitudinal direction and approximately in the center in the longitudinal direction. Telescopic column storage sections 9 store telescopic columns (support columns) 12. The telescopic columns 12 are provided to balance the load depending on the position of the transported object 20 when the upper slide 10 is slid in the longitudinal direction from the lower slide 11.

[0020] As shown in Fig. 3, an eyebolt fixing hole 14 is provided in the frame on the short side of the upper slide 10. For example, two eyebolt fixing holes 14 are provided in one frame, and the upper slide 10 is provided with four eyebolt fixing holes 14. An eyebolt 15 can be detachably attached to the eyebolt fixing hole 14. For example, the eyebolt 15 has a male thread and the eyebolt fixing hole 14 has a female thread, and the eyebolt 15 can be attached to the eyebolt fixing hole 14 by screwing.

[0021] When the heavy object transport device 1 is transported by a transport vehicle such as a truck or a trailer, the eye bolt 15 is attached when the heavy object transport device 1 is lifted onto the bed of the truck by a crane or the like, or when the heavy object transport device 1 is unloaded from the bed. The eye bolt 15 can be removed from the eye bolt fixing hole 14 when the heavy object transport device 1 is installed at a construction site or the like.

[0022] The operation of the weight transport device 1 according to the embodiment will be described. 4 and 5 are schematic side views for explaining the operation of the weight transport device according to the embodiment. In the heavy load transport device 1, the height adjustment pipes 8 can be set to a desired height by the hydraulic pump 7. As shown by the arrows in Fig. 4, the height of six height adjustment pipes 8 provided at six locations (three locations are shown because Fig. 4 is a side view) of the rectangular frame of the lower slide 11 can be increased by the hydraulic pump 7.

[0023] In the example of Fig. 4, all the height adjustment pipes 8 are set to the same height, but the heights of the six height adjustment pipes 8 can be set to different heights. For example, among the height adjustment pipes 8 shown in Fig. 4, the height of the rightmost height adjustment pipe 8 can be set lower than the heights of the other height adjustment pipes 8. Even if there is a step between the center height adjustment pipe 8 and the rightmost height adjustment pipe 8 in Fig. 4, the lower slide 11 and the upper slide 10 can be kept in a substantially horizontal state.

[0024] The height adjustment pipes 8 and hydraulic pumps 7 are provided at six locations on the rectangular frame of the lower slide 11, so that the lower slide 11 and upper slide 10 can remain almost horizontal even when there are steps as mentioned above, as well as longitudinal and lateral inclinations, and even when the road surface conditions of the transport route are a combination of these.

[0025] The heavy load transport device 1 installed on a predetermined transport path causes the upper slide 10 to slide substantially horizontally from the lower slide 11 by the slide operation mechanism 13, as shown by the arrow in FIG.

[0026] When the upper slide 10 is slid, the telescopic column 12 is extended from the telescopic column storage section 9 in the direction in which the upper slide 10 slides. The extended telescopic column 12 can support the end of the slid upper slide 10.

[0027] The upper slide 10 can be slid further in the direction indicated by the arrow than in the state shown in Fig. 5. For example, when the upper slide 10 is slid to its maximum extent, the longitudinal length of the heavy object transport device 1 can be approximately twice the longitudinal length of the upper slide 10. By also pulling out the telescopic column 12 located approximately in the center of the longitudinal direction of the upper slide 10, the upper slide 10 can be slid to its maximum extent in a stable and safe manner.

[0028] A method of using the weight transport device 1 according to the embodiment will be described. For example, first, at the transportation source, the transported object 20 is placed on the upper slide 10 of the heavy object transporting device 1 and loaded onto a transport vehicle, and then transported to the destination construction site. When the heavy object transporting device 1 with the transported object 20 loaded thereon is loaded onto the transport vehicle, it is lifted onto the bed of the transport vehicle by, for example, a crane, as described in relation to FIG. 3. The eyebolt 15 is screwed into the eyebolt fixing hole 14 of the upper slide 10, and the hook of the crane is engaged with the eyebolt 15, so that the loading operation can be performed stably and safely. Needless to say, when the heavy object transporting device 1 is transported, the upper slide 10 is not slid but is aligned with the lower slide 11.

[0029] After arriving at the destination construction site, the heavy load transporting device 1 is unloaded from the transport vehicle with the load 20 placed on the upper slide 10. In the same manner as when loading the heavy load transporting device 1 onto the transport vehicle, for example, the hook of a crane is engaged with the eye bolt 15 to lift the heavy load transporting device 1.

[0030] The position at which the heavy object transporting device 1 is installed is set based on the installation position of the transported object 20, the longitudinal length of the lower slide 11, and the slidable length of the upper slide 10. If the heavy object transporting device 1 is installed so that the installation position mark 3 coincides with the installation position of the transported object 20 when the upper slide 10 is slid, installation of the transported object 20 becomes easy. In the following explanation, it is assumed that the heavy object transporting device 1 is installed so that the installation position mark 3 coincides with the installation position of the transported object 20.

[0031] When installing the heavy load transport device 1, as described in relation to FIG. 2, the height of the height adjustment pipe 8 is adjusted by operating the hydraulic pump 7 according to the flatness of the transport path. By appropriately adjusting the height of the height adjustment pipe 8, the transport surface of the upper slide 10 can be made substantially horizontal (substantially vertical to the direction of gravity). After installing the heavy load transport device 1 on the transport path, it is preferable to remove the eye bolt 15 from the eye bolt fixing hole 14. By removing the eye bolt 15, the transported object 20 can be moved to the end of the upper slide 10 when the transported object 20 is transported by the transport rollers 4 described later.

[0032] After the conveying surface of the upper slide 10 is set as described above, the upper slide 10 is slid from the lower slide 11 via the slide operation mechanism 13 as described in relation to Fig. 5. The conveyed object 20 on the upper slide 10 moves in the sliding direction together with the upper slide 10.

[0033] When the upper slide 10 reaches an appropriate sliding position, the telescopic column 12 is pulled out from the telescopic column storage section 9 to stabilize the installation state of the heavy load transport device 1 on the transport path. After pulling out the telescopic column 12, the upper slide 10 is further slid until the installation position mark 3 coincides with the installation position of the transported load 20.

[0034] The drive motor 2 is operated to rotate the transport rollers 4 , thereby transporting the transported object 20 to the installation position mark 3 .

[0035] After the transported item 20 reaches the installation position mark 3, the transported item 20 is lifted from the upper slide 10 by a crane or the like, and with the transported item 20 lifted, the upper slide 10 is slid in the opposite direction to that described above via the slide operation mechanism 13 and stored on the lower slide 11 side.

[0036] When the lifted transported object 20 is lowered as is, the transported object 20 is placed at the desired placement position.

[0037] Thereafter, for example, the single heavy object transport apparatus 1 is loaded again onto the transport vehicle by a crane or the like, and returns to the transport source in order to transport another object.

[0038] The effects of the weight transport device 1 according to the embodiment will be described. The heavy object transporting device 1 according to the embodiment includes a plurality of height adjustment pipes 8, which support the lower slide 11, the upper slide 10, and the object 20 to be transported from below. The plurality of height adjustment pipes 8 are arranged, for example, at the four corners of the lower slide 11 and at approximately the center of the two frames on the longer sides of the lower slide 11 in a plan view. The height of each of the plurality of height adjustment pipes 8 can be adjusted according to the unevenness and inclination of the transport path on which the heavy object transporting device 1 is installed. Therefore, the heavy object transporting device 1 can be stably installed on the transport path.

[0039] Further, a plurality of hydraulic pumps 7 are provided on each of the plurality of height adjustment pipes 8. Each of the plurality of hydraulic pumps 7 can set the height adjustment pipe 8 to a desired height, and can safely adjust the height of each of the plurality of height adjustment pipes 8 relative to the transport path on which the heavy object transport device 1 is installed.

[0040] The heavy load transport device 1 further includes a lower slide 11 and an upper slide 10. The upper slide 10 is provided on the lower slide 11 via a slide operation mechanism 13, and the upper slide 10 can slide in the longitudinal direction from the lower slide 11 by the slide operation mechanism 13. By sliding the upper slide 10, the longitudinal length from the lower slide 11 to the upper slide 10 can be extended to the longitudinal lengths of the lower slide 11 and the upper slide 10. Therefore, the load 20 placed on the upper slide 10 can move together with the upper slide 10 on the transport path.

[0041] The upper slide 10 has a plurality of moving rollers 4 driven by a driving mechanism such as a driving motor 2 and a chain. The rotation axes of the plurality of moving rollers 4 are arranged perpendicular to the sliding direction of the upper slide 10, and the plurality of moving rollers 4 are lined up in the direction in which the upper slide 10 slides. By rotating the plurality of moving rollers 4, the transported object 20 placed on the plurality of moving rollers 4 can move along the direction in which the upper slide 10 slides. Therefore, the transported object 20 on the plurality of moving rollers 4 can move in the direction in which the upper slide 10 slides on the transport path.

[0042] The upper slide 10 has a telescopic column 12 that is provided so as to extend downward when slid. By the telescopic column 12 extending downward when slid, the upper slide 10 can be stably supported with respect to the transport path.

[0043] An installation position mark 3 is provided on the longitudinal end of the upper slide 10. The upper slide 10 is slid so that the installation position mark 3 coincides with the position of the installation location of the transported object 20, and the transported object 20 can be moved above the installation location by the moving rollers 4. After being moved above the installation location, the transported object 20 can be lowered directly downward by a crane or the like, and installed at the desired location.

[0044] In this way, a heavy load transporting device that can transport heavy loads safely in a short time can be realized.
