  Next, the operation of the cable drum transport device of this embodiment will be described.

  First, as shown in FIG. 3A, the worker who carries the cable drum transport operation selects a combination of through-holes into which the rod-like members 7 are inserted, in accordance with the size of the cable drum D to be transported. For example, in the case of a cable drum D having a small diameter (for example, a diameter of 700 mm), the through hole 11a is selected from the front through holes 11a and 11b in the rolling direction, and the rear through holes 11c to 11e are selected. The through hole 11e is selected from the inside. On the other hand, in the case of a cable drum D having a large diameter (for example, 2000 mm), the front through hole 11b and the rear through hole 11c are selected.

  Next, the rod-like member 7 is inserted and connected only to the through-hole 11 on the front side in the rolling direction of the cable drum D among the selected through-holes 11, and the rear-side rod-like member 7 is removed from the housing member 1. Remove it. In this state, the cable drum D to be transported is horizontally rolled from the other end side (left side of the drawing) of the housing member 1 to the floor surface and is housed between the pair of housing members 1. When the cable drum D comes into contact with the rod-like member 7 on the front side in the rolling direction, the rod-like member 7 is inserted into the through-hole 11 on the rear side in this state, and the rear side of the cable drum D is brought into contact with the rod-like member 7. The cable drum D is held in contact.

  For example, when the cable drum D having a diameter of 2000 mm is transported, the rod-shaped member 7 is inserted into the through-hole 11b on the front side in the rolling direction of the cable drum D in advance, and the rod-shaped member 7 on the rear side. The cable drum D is accommodated between the accommodating members 1 in a state in which is removed. When the front side of the cable drum comes into contact with the rod-like member 7 when inserted into the through hole 11b, the rod-like member 7 is inserted into the through-hole 11c on the rear side, and the rear side of the cable drum D also comes into contact with the rod-like member 7. The cable drum D is held.

  Here, when the rod-shaped member 7 is inserted into the through-hole 11 and connected, the connection is strengthened so that the notch 71 of the rod-shaped member 7 faces upward as described above. And the lower portion of the opposing member 1 is fitted to the notched portion 71 by reversing it at a position where the notched portion 71 coincides with the opposing member 1. When the rod-like member 7 is inserted through the through hole 11 and rotated, a hexagon wrench or the like can be used in combination with the hexagon hole 72 as necessary.

  Next, when the cable drum D is held in contact with the pair of rod-like members 7, the operator attaches the handle 61 to the jack 6, rotates the handle 61, and lowers the arm portion 62. As a result, as shown in FIG. 3B, the elevating member 4 connected to the arm portion 62 is displaced downward with respect to the lift member 2, and as a result, the lift member 2 is lifted upward with respect to the floor surface. It is done. Since the lift member 2 is integrated with the housing member 1, one end side of the housing member 1 is lifted, and the cable drum D held in contact with the rod-like member 7 slightly floats from the floor surface.

  With the cable drum D floating from the floor surface, the operator removes the handle 61 from the jack 6 and pushes and pulls the handle member 8 to carry the cable drum D. At this time, since the cable drum D does not have a portion in contact with the floor surface, the cable drum D is smoothly transported forward, backward, left and right by the rollers 12 and the casters 42.

  Then, after the cable drum D arrives at a predetermined position of the transport destination, the handle 61 is attached to the jack 6 again, and the handle is rotated in the direction in which the arm portion 62 is raised. As a result, the elevating member 4 connected to the arm portion 62 is displaced upward with respect to the lift member 2, and as a result, the lift member 2 is lowered with respect to the floor surface, and the cable drum D that has been levitated again becomes the floor. Land on the surface. In this state, the operator can remove the rod-like member 7 on the rear side holding the cable drum D from the through hole 11c and release the cable drum D from the transport device. When removing the rod-shaped member 7, a hexagon wrench can be used in combination with the hexagon hole 72 as necessary.

  Thus, according to the carrying device of the present invention, there is no need to push up the cable drum D onto the frame 5 using a slope-shaped auxiliary tool or the like, and the cable drum D can be easily lifted from the floor surface to carry out the carrying work. Can be performed efficiently and safely.

  In this embodiment, in the illustrated example, the elevating member can be moved up and down by inserting a bolt member through the slide hole. However, the present invention is not limited to this, for example, at both ends of the elevating member. A guide portion such as a convex portion may be provided so that the guide portion can slide along the slide groove or the slide hole.

  In the present embodiment, the driving means is a jack connected to the elevating member. However, the driving means is not limited to this, and may be, for example, a hydraulic lift that moves up and down by hydraulic pressure.
