  Hereinafter, an embodiment of a material transfer device according to the present invention will be described with reference to the drawings. In addition, the same code | symbol is attached | subjected to the common member in each figure.

  FIG. 1 is a diagram showing a material transfer device 100 as a first embodiment of a material transfer device according to the present invention. FIG. 2 is a plan view of the material transfer apparatus 100 shown in FIG. The material transfer apparatus 100 is used in a construction site and includes a pair of rails 11 configured by two rails 11 ′ and 11 ″. As shown in FIG. 2, each of the rails 11 'and 11' 'of the pair of rails 11 includes a bottom plate 11a and two side plates 11b1 and 11b2 that are connected to both side portions of the bottom plate 11a and extend upward. . A plurality of rollers 13 that rotate along the extending direction of the pair of rails 11 are disposed between the side plate 11b1 and the side plate 11b2. The roller 13 is rotatably connected to each of the side plate 11b1 and the side plate 11b2 by a bolt 14. When the material 200 such as a formwork or soil is transferred using the material transfer device 100, the material 200 is placed on the plurality of rollers 13 (see FIGS. 5 and 6A to 6C). That is, the upper part of the roller 13 constitutes a placement surface on which the material is placed. The material of the roller 13 can be metal, rubber, resin, or the like. The pitch of the rollers 13 is, for example, 10 cm to 30 cm.

  In addition to or in addition to the roller 13 as a conveying member, another conveying member can be provided. For example, a bearing can be provided. Moreover, the upper surface of a pair of rail 11 can also be used as a belt conveyor.

  The material transfer apparatus 100 further includes a crosspiece 12. The crosspiece 12 is rotatably connected to the bottom plate 11a of each of the pair of rails 11 by a pin member. Then, by rotating the crosspiece 12 with respect to the two bottom plates 11a, the distance between one rail 11 ′ and the other rail 11 ″ can be changed while keeping the pair of rails 11 parallel. it can. The material transfer apparatus 100 can take, for example, a folded form, a completely opened form of a ladder, and a form between them. In addition, you may utilize a volt | bolt as a pin member which connects the crosspiece 12 and each bottom plate 11a of a pair of rail 11. FIG. In this case, by setting the bottom plate 11a not to be strongly clamped between the bolt and the nut, the crosspiece 12 can be rotatably connected to the two bottom plates 11a.

  The material transfer apparatus 100 includes a height adjustment mechanism 21. The height adjusting mechanism 21 is provided with a hollow rod-like member 22 that supports the pair of rails 11. The hollow rod-like member 22 extends orthogonally to the pair of rails 11 when viewed from above in the vertical direction. Further, in this embodiment, the height adjusting mechanism 21 is disposed at different positions in the width direction of the pair of rails 11 and is connected in parallel with each other at a predetermined interval by a triple clamp as a connecting tool. Two hollow rod-like members 24 are provided. The two hollow rod-like members 24 extend along the extending direction of the pair of rails 11 as viewed from above in the vertical direction. Each of the two rod-shaped members 24 is connected to the rod-shaped member 22 by a movable clamp 23 and can swing around the rod-shaped member 22 as a fulcrum. The height adjusting mechanism 21 is provided with a hollow rod-like rail support member 25 that engages with one end of each of the pair of rails 11 from below and supports the pair of rails 11. The rail support member 25 is attached to one end of the two rod-shaped members 24 on the basis of the position of the rod-shaped member 22 as a fulcrum by a fixed clamp as a connecting tool. The rail support member 25 extends orthogonally to the pair of rails 11 when viewed from above in the vertical direction, like the rod-shaped member 22. In the example of this embodiment, the number of the rod-shaped members 24 is two, but may be one or three or more.

  That is, the height adjusting mechanism 21 includes a rod-shaped member 22 as a fulcrum and a swinging member 26 that can swing around the rod-shaped member 22 via a movable clamp 23. The swing member 26 according to the present embodiment includes the above-described rod-shaped member 24 and rail support member 25.

  Here, the oscillating member 26 includes an operating portion located on one side with respect to the position of the rod-shaped member 22 as a fulcrum, and an engaging portion located on the other side opposite to the operating portion across the rod-shaped member 22. And. The engaging portion is a portion that engages with the pair of rails 11, and is configured by a rail support member 25 in the present embodiment. In addition, the operation unit is a part operated by an on-site worker or a heavy machine 300 (see FIGS. 6A to 6C). In the present embodiment, one of the two rod-shaped members 24 is based on the rod-shaped member 22. It is constituted by the entire side portion 24e1. It should be noted that, for easy operation by workers and heavy equipment 300 (see FIGS. 6A to 6C), for example, a plate between the two rod-shaped members 24 on one side of the two rod-shaped members 24 with the rod-shaped member 22 as a reference. A rod-like or bar-like connecting member may be installed, and the operating portion may be configured by this connecting member.

  When a force is applied to one portion 24e1 of the rod-shaped member 24 as the operation portion and the portion 24e1 as the operation portion is moved downward in the vertical direction, it is attached to the other portion 24e2 of the two rod-shaped members 24. The rail support member 25 is moved upward in the vertical direction. Thus, when the rod-shaped member 24 is swung counterclockwise around the rod-shaped member 22 as a fulcrum (see the arrow in FIG. 3), the rail support member 25 moves upward in the vertical direction, and a pair of rails 11, one end 11 e 1 side of the pair of rails 11 is lifted upward in the vertical direction. As described above, the rail support member 25 of the swing member 26 of the height adjustment mechanism 21 is engaged with the pair of rails 11, thereby moving the one end 11 e 1 of the pair of rails 11 to a position higher than the other end 11 e 2. Can do. Thereby, as will be described later with reference to FIGS. 6A to 6C, the material transfer apparatus 100 can easily transfer the material 200, and therefore workability can be improved. Moreover, the force required when fluctuating the height of the ends 11e1 of the pair of rails can be reduced by the lever principle.

  Here, in this embodiment, the center of gravity of the swinging member 26 is located on the opposite side of the engaging portion that engages with the pair of rails 11 with respect to the rod-shaped member 22 as a fulcrum of the swinging member 26. It is shifted to the part side. That is, the position of the center of gravity of the swing member 26 of the present embodiment is opposite to the position where the rail support member 25 is provided from the position supported by the rod-shaped member 22, that is, one end 24 e 1 of the rod-shaped member 24. Close to the side. The center of gravity of the swing member 26 can also be designed so as to be located on the fulcrum of the swing member 26. When the application of external force to the one side portion 24e1 of the rod-shaped member 24 as the operation portion is stopped, the rail support member 25 as the engagement portion shown in FIG. As a result of the rail support member 25 as the engaging portion shown in FIG. 1 being lowered downward in the vertical direction from the state in which one end 11e1 is lifted vertically with respect to the other end 11e2, the pair of rails 11 are rod-shaped members 22. The two ends 11e1 and 11e2 of the pair of rails 11 are automatically returned to the same height. Thus, in the material transfer apparatus 100 of this embodiment, since the operation | work which returns a pair of rail 11 to the state shown in FIG. 1 from the state shown in FIG. 3 becomes unnecessary, workability | operativity can be improved more.

  In the material transfer device 100 of this embodiment, as described above, the two rod-like members 24 of the swinging member 26 are paired at different positions in the width direction of the pair of rails 11 as viewed from above in the vertical direction. It arrange | positions so that the extension direction of the rail 11 may be followed. The rail support member 25 of the swing member 26 is supported by the two rod-shaped members 24 in this embodiment at different positions in the width direction of the pair of rails 11 and is engaged with each of the pair of rails 11 from below. To do. With such a configuration, the force that the rail support member 25 exerts on the pair of rails 11 causes the pair of rails 11 to rotate around its extending direction, that is, the height position of one rail 11 ′. It can suppress that it rotates so that the relationship with the height position of the other rail 11 '' may fluctuate.

  Preferably, as shown in FIG. 1, the height on one end 11 e 1 side of the pair of rails 11 is a pair of rails in a state where an external force is not applied to one portion 24 e 1 of the rod-shaped member 24 as the operation unit. 11, the rail support member 25 as an engaging portion is engaged with the pair of rails 11 at a position equal to or lower than the height on the other end 11e2 side (the same height in FIG. 1). By setting the position of the rail support member 25 as the engaging portion in this way, the operator can lift the pair of rails 11 without largely moving the one side portion 24e1 of the rod-like member 24 as the operation portion. it can. Note that this configuration can be realized, for example, by adjusting the position of the movable clamp 23 attached to the rod-like member 24 or attaching a weight to any end portion of the rod-like member 24.

  Preferably, as shown in FIG. 4, the material transfer device 100 further includes stopper members 31 on both sides in the width direction of the pair of rails 11. The stopper member 31 extends in the vertical direction, and defines that the pair of rails 11 move in the width direction when the pair of rails 11 swing from the state of FIG. 1 to the state of FIG. Thereby, it can suppress that the position of a pair of rail 11 moves to the width direction unintentionally. In the embodiment shown in FIG. 4, the stopper member 31 is coupled to the rod-shaped member 22 using a coupling tool. However, the stopper member 31 may be fixed by being buried in soil. In FIG. 4, for convenience of explanation, a part of the stopper member 31 is omitted, and the outer shape is shown by a two-dot chain line.

  Next, referring to FIG. 5 and FIGS. 6A to 6C, a pair of rails 11 each having a placement surface on which the material 200 is placed, and a height adjusting mechanism 21 that makes one end of the pair of rails 11 higher than the other end. An embodiment of a material transfer method for transferring the material 200 by the material transfer device 100 including the above will be described.

  (Step 1) As shown in FIG. 5, the material transfer apparatus 100 is used in a construction site where a building foundation 500 is provided. The foundation 500 of this embodiment is a cloth foundation. For easy understanding, the base 500 is indicated by a two-dot chain line. In order to prevent the material transfer device 100 from rotating around its extending direction, a prismatic support member 600 is provided on the foundation 500, and four pieces are assembled in a well shape on the support member 600. The base is formed by arranging the pipes 610a-d. In the example of the present embodiment, the four pipes 610a-d are arranged in the information of the foundation 500 via the support member 600, but the four pipes 610a-d are used as the foundation without using the support member 600. You may arrange directly on 500.

  A pair of rails 11 of the material transfer apparatus 100 are disposed on the four pipes 610a-d. More specifically, the pair of rails 11 of this embodiment is supported from below by one end 11e1 side and the other end 11e2 side by two pipes 610a and 610b arranged to face each other in a top view. It is constructed between these two 610a and 610b. Then, the movable clamp 23 is attached to the two rod-shaped members 24. Thereafter, the movable clamp 23 is attached to a pipe 610a which is a pipe perpendicular to the pair of rails 11 when viewed from above and close to one end 11e1 of the pair of rails 11. The pipe 610a becomes a fulcrum of the swing member 26 of the material transfer apparatus 100. That is, the pipe 610a in FIG. 5 corresponds to the rod-shaped member 22 in FIG. In this way, the material transfer device 100 can be installed.

  (Step 2) As shown in FIG. 6A, on the placement surface of the pair of rails 11, in front of the height adjusting mechanism 21, a material 200 such as a mold or soil is loaded by a heavy machine 300 (in this embodiment, the material is mounted). (Including the loading platform and containers). At this time, both ends 11e1 and 11e2 in the extending direction of the pair of rails 11 have substantially the same height.

  (Step 3) After the material 200 is placed on the placement surface of the pair of rails 11, as shown in FIG. 6B, the bucket of the heavy machine 300 serves as a rod-shaped operation unit for the swing member 26 of the height adjustment mechanism 21. The part 24e1 on one side of the member 24 is pushed down, and the swinging member 26 is swung in the direction indicated by the arrow (clockwise in FIG. 6B). Then, since the rail support member 25 of the swing member 26 is engaged with the one end 11e1 of the pair of rails 11, the swing member 26 is one end 11e1 of the pair of rails 11 as described with reference to FIG. To move the one end 11e1 of the pair of rails 11 to a position higher than the other end 11e2. By tilting the pair of rails 11 in this way, the material 200 can be slid on the pair of rails 11 in the direction indicated by the arrow in FIG. 6B (the left direction in FIG. 6B) and the material 200 can be transferred. .

  As shown in FIG. 6C, the pair of rails 11 is connected to the other pair of rails 16-18. After the material 200 slides on the pair of rails 11, it further slides on the pair of rails 16-18. In this embodiment, the pair of rails 16 are disposed with an inclination in advance, and the pair of rails 17-18 are disposed below the pair of rails 11. Therefore, the material 200 accelerates when sliding on the inclined pair of rails 16, and as a result, the material 200 can be transferred further. In addition, when there is no need to transfer the material 200 so far, the pair of rails 16 need not be inclined.

  (Step 4) As shown in FIG. 6C, the worker 400 disposed near the ends of the pair of rails 18 on the side opposite to the pair of rails 17 receives the material 200. The worker 400, for example, tilts the material 200 (here, the container containing the soil) and drops the soil around the foundation 500 shown in FIG. The fallen customer soil is used as backfill soil for root cutting. In addition, a stopper can be provided in the edge part on the opposite side to the connection part with a pair of rail 17 of a pair of rail 18. As shown in FIG. In this case, the work for the worker 400 to receive the material 200 can be made unnecessary.

  (Step 5) When the worker 400 pushes the material 200 that is an empty container from the pair of rails 18 toward the pair of rails 11, the material 200 is transferred in a direction opposite to that of Step 3-4. . At this time, the portion 24e1 on one side of the rod-like member 24 as the operating portion of the swing member 26 is not pushed down by the heavy machine 300, and as described above, the swing member 26 is shown in FIGS. As shown in FIG. 5, the rail support member 25 side of the rod-like member 24 is returned to the lowered state. Therefore, the material 200 transferred in the reverse direction can collide with the height adjustment mechanism 21 and stop before the height adjustment mechanism 21 as shown in FIG. 6A. That is, the operating portion of the swing member 26 also serves as a stopper against which the material 200 abuts on the one end 11e1 side of the pair of rails 11.

  A large amount of land can be transferred by repeating the above steps 2 to 5 several times. Note that steps 1 to 5 can be performed only once.

  As described so far, when the material transfer apparatus 100 is used, the heavy machine 300 can transfer the material 200 only by pushing down the operating portion of the swing member 26 of the height adjustment mechanism 21. Therefore, the worker who is arranged near the pair of rails 11 and transports the material 200 becomes unnecessary. Since the range within which the arm of the heavy machine 300 reaches is dangerous for the worker, the material transfer device 100 can move the worker away from the heavy machine 300 and can transfer the material 200 more safely. However, the material 200 can also be transferred by the operator pressing down the operating portion of the swing member 26 of the height adjusting mechanism 21. In this case, according to the lever principle, the worker can transfer the material 200 by pushing down the operation portion of the swing member 26 with a relatively small force.

  FIG. 7 is a view showing another connection form of the pair of rails of the material transfer apparatus 100. In this connection configuration, the pair of rails 11 shown in FIGS. 1 to 3 are referred to as a first pair of rails 11. Then, a second pair of rails 16 having the same configuration as the pair of rails 11 is connected to the first pair of rails 11.

  Each rail of the first pair of rails 11 includes a plate-like protruding portion 11c extending from one end in the extending direction of the bottom plate 11a. The plate-like protruding portion 11c is provided with a hole 11d as a first connecting portion, and the bolt 50 can be inserted into the hole 11d. Further, each bottom plate 16a of the second pair of rails 16 is provided with a hole 16e as a second connection portion. The first pair of rails 11 are provided with a bolt 50 having a hole 11d as a first connection portion and a hole 16e as a second connection portion overlapped in the vertical direction and the shaft passing through these holes. The second pair of rails 16 are connected. By setting the bolts 50 not to be tightened by the nuts, the first pair of rails 11 can be made to a plane including the second pair of rails 11 with respect to the second pair of rails 16 (see FIG. 7). In a parallel plane), it can be pivotally connected around the axis of the bolt 50.

  In the material transfer device 100 of this connection form, in the state where the first pair of rails 11 and the second pair of rails 16 are coupled, the extending direction d1 of the first pair of rails 11, The extending direction d2 of the two pairs of rails 16 can be freely changed. Therefore, when changing the material transfer destination, for example, the pair of rails 16 close to the material transfer destination are rotated with respect to the other pair of rails 11 without moving the pair of rails 11. It is possible to change the material transfer destination. Thus, in the material transfer apparatus 100 of this connection form, the transfer destination of a material can be changed easily and workability | operativity of material transfer can be improved.

  By the way, although a temporary enclosure, a refuge, etc. may be provided in a construction site, these members may become an obstacle at the time of transferring materials. In such a case, in the material transfer device 100 of this embodiment, the extending direction d1 of the first pair of rails 11 and the extending direction d2 of the second pair of rails 16 are avoided. Can be set as follows.
