Reference numeral 42 denotes a rail laid on the work floor F on which the carriage 43 and the battery locomotive 44 run, as shown in FIGS. 1, 2, 8, and 10, from below the material storage box stockers C1 and C2. It extends to the vicinity of the shield machine 46 in the horizontal shaft 45. In addition, 42a shown in FIG. 2 is a crossover line.

Next, the material storage box stockers C1 and C2 having the above-described configuration are used to temporarily store a plurality of material storage boxes B in the vertical shaft 10 in a multi-tiered manner, and to temporarily store the material storage boxes B. Are transferred to the carriage 43. Here, of the plurality of material storage boxes B stacked in multiple stages, the lowest one is B1,
The material storage boxes stacked on the upper side are shown as B2, B3... In order from the bottom.

<Stacking operation of material storage box> First, in order to supply the material storage box B1 to the material storage box stocker C1,
The material storage box B1 mounted on the transport vehicle 12 stopped to the side of the bridge type crane A is lifted by the above-described bridge crane A, and the material storage box B1 in the shaft 10 is lifted.
After moving above, it is suspended inside.

When the suspended material storage box B1 is suspended in the storage box storage section E, it descends while being guided by the spacers 41, and then moves to the support position (a) as shown in FIG. In addition to being supported by the box support unit 35 that is being carried out, it is also supported by the box support mechanism D1.

That is, the material storage box B1 is provided with the box support mechanism D1 in the rod fitting holes 19 of the holding frame 17 on the upper side thereof.
The rods 34a of the box supporting hydraulic jacks 34 are fitted, and the rod fitting holes 19 of the lower holding frame 18 are fitted.
The box supporting hydraulic jack 38 of the box supporting unit 35
Are supported in a fitted state.

The material storage box B1 is connected to the box support unit 3
5. After being supported by the box supporting mechanism D1, the next material storage box B2 is suspended in the material storage box stocker C1 by the bridge crane A and the box lifting unit 14, as shown in FIG. Stack directly on the storage box B1.

By repeating the stacking operation as necessary,
As shown in FIG. 13, the material storage box B is stored in the storage box storage section E.
1 to B8 are stacked in multiple stages.

<Transferring operation of material storage box> Material storage box B1
13, the box supporting unit 35 is released from the support state of the lowermost material storage box B1 by the box supporting mechanism D1, as shown in FIG.
Is lowered so that the upper holding frame 17 of the material storage box B2 faces the box supporting hydraulic jacks 34 of the box support mechanism D1.

Next, the box supporting hydraulic jacks 34 of the box supporting mechanism D1 are driven to extend, and as shown in FIG. 15, these rods 34a are connected to the upper holding frame 17 of the material storage box B2. Fit into the rod fitting holes 19. As a result, the entire material storage boxes B2 to B8 except for the lowermost material storage box B1 are supported by the box support mechanism D1.

Rods 38 of box supporting hydraulic jacks 38.
The box support unit 35 is moved down from the support position (a) to the transfer position (b) with the a inserted into the rod fitting holes 19 of the support frame 18 on the lower side of the material storage box B1, FIG.
The material storage box B1 is transferred to the carriage 43 as shown in FIG. Then, the box supporting hydraulic jacks 38 are retracted and driven to move the rods 38a through the rod fitting holes 19 of the holding frame 18.
.. Are removed, and the support state of the material storage box B1 is released.

The trolley 43 on which the material storage box B1 is mounted is pulled by the battery locomotive 44, travels in the horizontal shaft 45, and stops near the shield machine 46, where the segment 15 stored in the material storage box B1 is located. ... is taken out.

The empty material storage box B1 from which the segments 15 have been taken out is transported to the material storage box stocker C2 by the cart 43, and then the material storage box B is moved in a reverse manner to the above-described operation of transferring the material storage box B. They are stacked in the storage box storage section E on the storage box stocker C2 side and temporarily stored. Therefore, even if there is an empty material storage box B to be carried out during the night and there is an empty material storage box B to be carried out, it can be piled up in the material storage box stocker C2 and temporarily stored. It is not necessary to carry out empty material storage boxes B at night.

The present invention can be modified as follows. In the above description, the configuration in which the material storage box stockers C1 and C2 are arranged one by one along the wall surface of the shaft, but two or more material storage box stockers C1 and two or more material storage box stockers C2 are used. It may be configured in parallel.

Further, for example, two material storage box stockers C2 may be arranged corresponding to one material storage box stocker C1.

In the above description, the segment has been described as an example of the material. However, the material may be, for example, a steel material or a tool used for construction. Alternatively, the excavated earth and sand generated at the face may be filled and discharged into the empty material storage box after the material is taken out.

In this case, since the transported excavated earth and sand can be transported to another dump site with the material storage box filled in the material storage box, there is no need to reload the excavated earth and sand, thereby reducing costs. You can also plan.

Furthermore, since the material storage boxes filled with excavated earth and sand can be stored in a stacked state in the material storage box stocker, there is no need to carry out excavated earth and sand at night, and noise at night can be prevented. it can.

[0053]

According to the present invention, the following effects can be obtained. Since a plurality of material storage boxes can be directly stacked in multiple stages and stored in a shaft, more materials can be stored in a smaller space than in the case where materials such as segments are stored directly on shelves. Can be accommodated, and the installation area can be reduced.

Since the lowermost one of the multi-tiered material storage boxes is successively lowered to be transferred to the bogie, the transfer equipment is provided in a multi-tiered material storage box. Since it can be arranged below the box, the installation area can be further reduced. Therefore, it is only necessary to excavate a small shaft as much as possible to reduce the installation area,
The construction cost for shaft excavation can be reduced.

The material storage box can be transferred to the carriage only by a simple operation of sequentially lowering the lowermost one, so that the configuration relating to the transfer can be simplified.

Since the materials are stored in the material storage box,
For example, they may be piled up several times in a starting base provided with a shaft. As a result, the stockyard for that purpose can be reduced, and the inside of the starting base can be used effectively.
