  Hereinafter, embodiments will be described in detail with reference to the accompanying drawings. In the drawings attached to the present specification, for the sake of illustration and ease of understanding, the scale, the vertical / horizontal dimension ratio, and the like are appropriately changed and exaggerated from those of the actual product.

(First embodiment)
First, the configuration of the object conveying jig according to the first embodiment will be described with reference to FIGS.

  As shown in FIGS. 1 and 2, the object transporting jig 10 according to the first embodiment is provided on a plate-like member 20 having an upper surface 20a and a lower surface 20b, and is rotatably provided on the plate-like member 20. A plurality of (9 in FIG. 1) rotating bodies 11.

  Of these, the plate-like member 20 has a substantially rectangular plane shape, and each side thereof extends along the X direction and the Y direction. Although the magnitude | size of the plate-shaped member 20 is not limited, For example, it is preferable to set it as the magnitude | size which can be mounted in the outer frame of the mount frame 3 mentioned later. As a material of the plate member 20, for example, a metal such as stainless steel or aluminum may be used.

  As will be described later, each rotating body 11 serves to hold the heavy object 5 on the plate-like member 20 and rolls so as to move the plate-like member 20 on the gantry 3. Each rotating body 11 is composed of spheres having the same size, and the center thereof is at the same height (position in the Z direction) as the plate-like member 20. Since the rotator 11 is a sphere, the rotator 11 can rotate in any direction around the center of the sphere with respect to the plate-like member 20. It can rotate in any direction of 360 ° on the XY plane shown in FIG. That is, the object transporting jig 10 can be translated in all directions on the XY plane.

  However, the present invention is not limited to this, and each rotating body 11 may rotate in one direction. For example, the rotation axis of each rotating body may be parallel to the Y direction, and each rotating body may move only in the X direction. In this case, the rotating bodies 11 may be disk-shaped with the same size.

  The plurality of (9 in FIG. 1) rotating bodies 11 all protrude upward from the upper surface 20a of the plate-like member 20 and protrude downward from the lower surface 20b. In this case, among the plurality of rotating bodies 11, at least three rotating bodies that are not on the same straight line protrude upward from the upper surface 20 a of the plate-like member 20, and at least three rotating bodies that are not on the same straight line are the plate-like member 20. What is necessary is just to protrude below from the lower surface 20b. In the present specification, “the three rotating bodies are not on the same straight line” means that the centers of the three rotating bodies 11 are not on the same straight line in plan view and the centers of the three rotating bodies 11 form a triangle. To do.

  Further, in the present embodiment, as shown in FIG. 2 or 3, each rotating body 11 protrudes from both the upper surface 20 a and the lower surface 20 b of the plate-like member 20. As shown in FIG. 4, the rotating body 11 protruding upward from the upper surface 20a and the rotating body 11 protruding downward from the lower surface 20b may be configured separately.

  Each rotating body 11 is rotatably held by the plate-like member 20 by the rotating body holding part 12. The rotating body holding portion 12 may be a bearing having a shape corresponding to a spherical surface that can accommodate the rotating body 11, for example, and is preferably a ball bearing. Therefore, the friction between the rotating body 11 and the rotating body holding part 12 generated when the rotating body 11 rotates is reduced.

  On the upper surface 20a of the plate-like member 20, an elevating mechanism 21 capable of elevating is provided. As shown in FIG. 3, the elevating mechanism 21 is located above the apex 11a of the rotator 11, and an upper position for holding the heavy object 5 in a lifted state, and the rotator 11 as shown in FIG. It is located below the apex 11a of the, and can take a lower position away from the heavy article 5.

  The raising / lowering of the raising / lowering mechanism 21 may be performed by fluid pressure, for example, pneumatic pressure or hydraulic pressure. That is, the elevating mechanism 21 has a sealed space sealed therein, and pressure fluid (air or oil) is supplied to the sealed space from a fluid supply unit (not shown). When the pressure fluid is supplied in this way, the elevating mechanism 21 expands to take an upper position where the heavy object 5 is lifted. On the other hand, by releasing the supply of the pressure fluid to the sealed space, the elevating mechanism 21 contracts and takes a lower position away from the heavy object 5.

  A handle 22 is attached to the side surface of the plate-like member 20. The handle 22 is used when the object carrying jig 10 is taken out from below the heavy object 5 and may be detachably attached to the plate member 20. The handle 22 may be a handle or a string. As shown in FIG. 1, the handle 22 may be provided on all four sides of the plate-like member 20, or may be provided on only some of the four sides.

  The entire thickness of the object conveying jig 10 may be not less than 5 mm and not more than 30 mm. In this case, the thickness of the object conveying jig 10 is equal to the diameter of the rotating body 11 which is a sphere. By setting the overall thickness of the object conveying jig 10 to 5 mm or more and 30 mm or less, the object conveying jig 10 can be thinned. Thereby, even if it is a case where the clearance gap between the upper surface of the heavy article 5 and the ceiling of a building is narrow, the heavy article 5 can be conveyed effectively.

  Next, the operation of the present embodiment having such a configuration, that is, a method for transporting a heavy object using an object transport jig will be described.

  First, the object conveying jig 10 is placed on a base 3 such as a channel base. Subsequently, as shown in FIG. 5, by supplying pressure fluid (air or oil) from a fluid supply unit (not shown) to the sealed space of the lifting mechanism 21, the lifting mechanism 21 is set to the upper position. Thereafter, a heavy object 5 such as a switchboard is placed on the lifting mechanism 21 on the upper surface side of the object conveying jig 10 by a crane or the like (not shown). At this time, since the elevating mechanism 21 is located at an upper position, that is, above the rotating body 11, the heavy article 5 and each rotating body 11 do not contact each other. Accordingly, the object transporting jig 10 can be freely translated on the plane (the gantry 3) by the rotating body 11. On the other hand, the heavy object 5 remains loaded on the object conveying jig 10 and moves on the gantry 3 together with the object conveying jig 10.

  After moving the object conveying jig 10 loaded with the heavy object 5 to the target place, the lifting mechanism 21 is moved to the lower position as shown in FIG. Specifically, the pressure fluid filled in the sealed space of the lifting mechanism 21 is released. At this time, since the elevating mechanism 21 is lowered and is positioned below the rotating body 11, the heavy object 5 and each rotating body 11 come into contact with each other, and the heavy object 5 and the elevating mechanism 21 are separated from each other. That is, the heavy object 5 is in contact with the object conveying jig 10 only by the rotating body 11. For this reason, the object conveying jig 10 can move with a small friction with respect to the heavy object 5. Subsequently, the object conveying jig 10 is removed from between the heavy object 5 and the gantry 3 while supporting the heavy object 5. In this case, the object conveying jig 10 can be easily pulled out from between the heavy object 5 and the gantry 3 by the handle 22. In this way, the heavy object 5 can be translated and the object carrying jig 10 can be recovered. Thereafter, the position of the heavy object 5 is finely adjusted on the gantry 3 as necessary, and the heavy object 5 is fixed to the gantry 3.

  As described above, according to the present embodiment, when the heavy object 5 is transported on the gantry 3, only the rotating body 11 of the object conveying jig 10 is in contact with the gantry 3. The heavy object 5 can be moved. Accordingly, the burden on the operator can be reduced when the heavy object 5 is transported on the gantry 3 by human power.

  Moreover, according to this Embodiment, the frictional resistance between the heavy article 5 and the object conveyance jig | tool 10 can be made small. Therefore, the object conveying jig 10 can be easily pulled out from between the heavy object 5 and the gantry 3, and the operator can perform the recovery operation of the object conveying jig 10 after conveying the heavy object 5 on the gantry 3. Can be reduced.

  Furthermore, according to this Embodiment, the whole thickness is 5 mm or more and 30 mm or less. Therefore, the heavy object 5 having a high height can be transported even in a place where the height of the work place is low. Further, since the center of gravity of the heavy object 5 is lowered, it is easy to be stable when the heavy object 5 is loaded.

  Further, according to the present embodiment, at least three rotators 11 that are spheres of the same size that are not on the same straight line protrude upward from the upper surface 20 a of the plate-like member 20. Accordingly, the heavy object 5 loaded on the object conveying jig 10 is kept horizontal with respect to the plate-like member 20. On the other hand, the rotating body 11 that is at least three spheres of the same size that are not on the same straight line protrudes downward from the lower surface 20 b of the plate-like member 20. Accordingly, the plate-like member 20 is kept horizontal with respect to the gantry 3. From these things, since the heavy article 5 is kept horizontal with respect to the mount frame 3, it can be conveyed more stably.

  In the above description, the case of moving the heavy object 5 on the gantry 3 using the object conveying jig 10 has been described as an example. However, the present invention is not limited to this, and the object conveying jig 10 may be used when the heavy object 5 is moved on the floor surface.

  As well shown in FIG. 8, the upper guide member 23 restricts the movement of the heavy article 5 loaded on the object transporting jig 10 in the X-axis direction. On the other hand, the movement of the object conveying jig 10 in the Y-axis direction is not restricted. For this reason, after the heavy article 5 is loaded and moved to the destination, the object conveying jig 10 can be pulled out in the Y-axis direction.

  According to the present embodiment, it is possible to prevent a problem that the heavy object 5 falls when the heavy object 5 is transported. Therefore, the heavy article 5 can be transported more safely and easily.

  As well shown in FIG. 10, the object conveying jig 10 restricts the movement in the X-axis direction so that the lower guide member 24 can move only in the direction along the gantry 3 (Y-axis direction in FIG. 9). Is done. On the other hand, the movement of the object conveying jig 10 in the Y-axis direction is not restricted. For this reason, after the heavy article 5 is loaded and moved to the destination, the object conveying jig 10 can be pulled out in the Y-axis direction.

  According to the present embodiment, it is possible to prevent a problem that the object carrying jig 10 is detached from the gantry 3 and dropped when the object carrying jig 10 is moved. Therefore, the object conveying jig 10 can be moved more safely and easily. The lower guide member 24 may be provided only at one end of the plate-like member 20. Further, both the upper guide member 23 (see FIGS. 7 and 8) and the lower guide member 24 described above may be provided on the plate-like member 20.
