<C> Elevating device As shown in FIG. 3, the elevating device 3 is a box that can be moved up and down and carries segments in the vertical direction. A mounting table 31 for the segment 4 is provided in the box of the lifting device 3, and a delivery space 32 for delivering the segment 4 to the transfer device 1 is provided in the center of the mounting table 31. Further, the installation height of the mounting table 31 from the bottom surface of the box secures a height at which the transfer device 1 can enter between the bottom surface of the box and the mounting table 31.
[0016]
【how to use】
Next, a segment conveying method using the conveying apparatus configured as described above will be described.
<A> Vertical transport As shown in FIG. 3, the required number of segments 4 are stacked and mounted on the mounting table 31 of the lifting device 3, and the lifting device 3 is lowered to the bottom of the shaft to perform vertical transport.
[0017]
<B> Transfer When the lifting device 3 arrives at the bottom of the shaft, the transport carriage 2 is brought close to the lifting device 3 and the transfer device 1 is run on the upper surface of the transport cart 2 so that the lifting device 3 is moved as shown in FIG. Between the bottom surface and the mounting table 31. Next, the lifting pan 16 of the transfer device 1 is extended to raise the receiving table 14 , and the segment 4 is transferred from the transfer space 32.
[0018]
When the segment 4 is delivered, as shown in FIG. 4, the transfer device 1 travels to the upper surface of the leading transport carriage 2 a and stops, and the turntable 13 is rotated to change the direction of the segment 4 by 90 degrees ( FIG. 5).
[0019]
Next, as shown in FIG. 5, the cradle 14 is lowered, the segment 4 on the cradle 14 is replaced with the support member 21 of the transport carriage 2a, and then the transfer device 1 is moved onto the transport carriage 2b. Let During this time, the lifting / lowering device 3 is raised to load the next segment and transported vertically to the bottom of the shaft again.
[0020]
<C> Horizontal transport When the lifting device 3 arrives at the bottom of the shaft, the transfer device 1 transfers the segment onto the transport carriage 2b in the same procedure as described above. When the one-component component segment is mounted on the transport carriage 2, the transport carriage 2 is pulled by the locomotive, and is transported horizontally in the horizontal shaft to the face.
[0021]
Second Embodiment of the Invention
In order to increase the number of segments that can be vertically conveyed at a time, the mounting device is provided in two stages in the lifting device 3, the lower mounting table 31 is fixed, and the upper mounting table 33 is configured to be moved up and down by a jack 34 or the like. It is possible to do.
[0022]
In this case, after the segment 4 on the lower mounting table 31 is transferred to the transfer device 1, the jack 34 is extended, and the upper mounting table 33 is lowered to the lower mounting table 31 to transfer the segment 4. Transfer to the device 1.
[0023]
Embodiment 3 of the Invention
FIG. 8 shows a case where the mounting table 35 in the lifting device 3 is configured to be lifted and lowered by a jack 36 or the like. In this case, since the segment can be mounted on the receiving table 14 of the transfer device 1 by lowering the mounting table 35, an elevating device such as the elevating panter 16 is not required on the receiving table 14.
