[0011]

Embodiment 1 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. <A> Transfer Device The transfer device 1 is a truck-shaped member as shown in FIG. 1 and is a device for transferring a segment between a lifting device and a transport truck. The transfer device 1 is provided with wheels 11 on a main body, and is configured to be able to run by a motor 12 by itself. It is preferable to configure the vehicle so that the vehicle can be remotely operated by radio.

The upper part of the main body is provided with a turntable 13 which rotates in the horizontal direction, and the upper part thereof is provided with a receiving stand 14 for the segments. The cradle 14 is supported by a lifting panter 16 that moves up and down by the expansion and contraction of a jack 15 so as to be able to move up and down. Also, at the four corners on the upper surface of the cradle 14,
Receiving member 1 for receiving segments in a stable state
7 are protruded.

<B> Carriage Carriage The carrier trolley 2, as shown in FIG. 2, has a segment mounted thereon and conveys it horizontally in a horizontal shaft or the like. Two or more transport vehicles 2 are connected and used, and a transfer device 1 is mounted on the upper surface thereof so as to be able to travel in the traveling direction of the transport vehicle 2.

At the four corners of the carrier 2, support members 21 are provided to project the segments from the transfer device 1 and mount the segments in a stable state. This support member 21
Lowers the pedestal 14 of the transfer device 1 on the carrier 2 so that the segments on the pedestal 14
It has a height that can be changed to 1.

<C> Lifting Device The lifting device 3, as shown in FIG. 3, is a vertically movable box body on which segments are mounted and transported in the vertical direction. A mounting table 31 for the segments 4 is provided in the box of the lifting device 3, and a transfer space 32 for transferring the segments 4 to the transfer device 1 is provided in the center of the mounting table 31. Also,
The installation height of the mounting table 31 from the bottom of the box ensures a height at which the transfer device 1 can enter between the bottom of the box and the mounting table 31.

[0016]

Next, a description will be given of a method of transporting a segment using the transport device configured as described above. <A> Vertical transfer As shown in FIG. 3, the required number of segments 4 are stacked and mounted on the mounting table 31 of the lift device 3, and the lift device 3 is lowered to the bottom of the shaft to perform vertical transfer.

<B> Transfer When the lifting device 3 arrives at the bottom of the shaft, the transport vehicle 2 is brought close to the lifting device 3, and the transfer device 1 is caused to travel on the upper surface of the transport vehicle 2 as shown in FIG. It is made to enter between the bottom surface of the lifting device 3 and the mounting table 31. Next, the lifting / lowering punter 1 of the transfer device 1
6 is extended and the cradle 14 is raised, so that the delivery space 32
Hand over the segment 4.

When the segment 4 is delivered and received, as shown in FIG. 4, the transfer device 1 is moved to the upper surface of the leading carrier 2a, stopped, and the turntable 13 is rotated to
Is changed by 90 degrees (FIG. 5).

Next, as shown in FIG. 5, the pedestal 14 is lowered and the segment 4 on the pedestal 14 is
After the transfer to the support member 21, the transfer device 1 is moved onto the carrier 2b. During this time, the lifting device 3 is raised to load the next segment, and is again vertically transported to the shaft bottom.

<C> Horizontal transfer When the lifting device 3 arrives at the bottom of the shaft, the segments are transferred onto the transfer carriage 2b by the transfer device 1 in the same procedure as described above. After the one component segment is mounted on the transport vehicle 2, the transport vehicle 2 is pulled by a locomotive, horizontally transported in a horizontal shaft, and travels to a face.

[0021]

[Embodiment 2] In order to increase the number of segments that can be vertically conveyed at one time, the mounting table must be
The lower stage 31 is fixed, and the upper stage 3 is fixed.
It is conceivable that 3 is configured to be able to move up and down by a jack 34 or the like.

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, so that the segment 4 Is transferred to the transfer device 1.

[0023]

[Embodiment 3] FIG. 8 shows a case where a mounting table 35 in an elevating device 3 is configured to be able to move up and down by a jack 36 or the like. In this case, since the segments 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.

[0024]

[Embodiment 4] FIG. 9 shows a case in which a box bottom plate 37 of an elevating device 3 is configured to be openable and closable. In this case,
Since the lifting / lowering device 3 can be lowered onto the transfer device 1 and the segment 4 on the mounting table 31 can be changed over the receiving table 14 of the transferring device 1 via the opened bottom, the receiving table 1
4 does not require an elevating device such as the elevating panter 16.

When the upper stage 38 is provided in the elevator 3, after the segments 4 on the lower stage 31 are transferred, the elevator 3 is further lowered into the pits 5, and The segments 4 on the mounting table 38 can be replaced on the receiving table 14 of the transfer device 1. In this case, the transport vehicle 1 is mounted on a traveling floor 51 installed in the pit 5. Note that the bottom surface of the lifting device 3 may not be openable and closable, but may be simply opened. Further, the first embodiment described above
Alternatively, the structure may be a combination of any of Nos. To 4 as appropriate.

[0026]

As described above, the present invention employs a method in which only a segment is mounted in an elevating device and vertically transported, and the segment is transferred to a transport trolley by a transfer device at the bottom of the shaft to perform horizontal transport. is there. Therefore, since the transport equipment in the shaft, such as the elevating device, can be reduced in size, the shaft can be used even in a small shaft, the cost can be reduced, and the space in the shaft can be effectively used.
