TECHNICAL FIELD OF THE INVENTION
The present invention relates to a material stocking apparatus and a material transporting method, and more particularly to a material stocking apparatus and a material transporting method for stocking a material in a plurality of stages in a vertical direction.
[0002]
BACKGROUND ART AND PROBLEMS TO BE SOLVED BY THE INVENTION
In general, for example, in factories, warehouses, construction sites, and the like, it is necessary to stock a large amount of materials, so that a large space for stocking these materials is required, and a wide area is required.
[0003]
However, it is often difficult to secure a wide site for material stock depending on the installation location of factories and warehouses, construction site conditions, and the like.
[0004]
In particular, when trying to construct underground structures such as tunnels by shield method in urban areas, etc., it is difficult to secure enough land around the shaft because of the lack of vacant land, etc. It is becoming difficult to secure space for stock.
[0005]
The purpose of this conventional shaft is to mainly use it as a starting and reaching base for shield excavators.The starting base is used to transfer various materials such as segments, rails, sleepers, etc. from the ground into the tunnel during the excavation period. It is used as a passage to carry in.
[0006]
In general, such materials are temporarily placed on a plane in a stock yard provided on the ground of a shaft, and are carried into a tunnel as needed.
[0007]
Under such circumstances, in order to reduce the space of the shaft site, a tunnel shaft structure as disclosed in Japanese Patent No. 2524904 has been proposed.
[0008]
In this tunnel shaft structure, a wall of appropriate thickness made of concrete or the like is formed on the peripheral wall surface of the shaft, and ring-shaped horizontal partition walls are formed on the inner peripheral surface of the wall at appropriate intervals in the vertical direction. On the partition wall, a storage room for materials for tunnel construction is formed.

[0012]
Also, when transporting materials into the shaft, at the supply port at the upper end of the shaft, the materials are taken into the stacker crane using a fork member from the bogie, and further stored in each partition wall using the fork member from the stacker crane. However, it is necessary to take the material stored in this partition wall into the stacker crane with a fork member, transport the material to the bottom of the shaft, and then transfer it to the bottom side of the shaft with a fork member. It is time-consuming and time-consuming.
[0013]
Furthermore, in such a transport state, when the material is to be stocked by effectively utilizing the empty space on the ground or the like, it is necessary to further transfer the stock from the stock position to the bogie, which further increases the labor of the transfer. Become.
[0014]
It is an object of the present invention to secure a sufficient amount of material stock even when it is difficult to secure a sufficient land for stocking the material, and to allow the material to be carried in and out without reloading the material. It is in.
[0015]
Another object of the present invention is to reduce the area of ground land by efficiently storing materials in a shaft of an arbitrary shape while sufficiently securing a space necessary for use in other applications in the shaft. It is in.
[0016]
Another object of the present invention is to enable loading and unloading between the ground equipment and the stock area and between the stock area and the bogie under the shaft without reloading the materials.
[0017]
Still another object of the present invention is to make it possible to stock a shaft in an arbitrarily arranged shaft and to make effective use of empty space.

In addition, accurate positioning with respect to the horizontal transfer rail 36 is performed to ensure a reliable transfer operation of the horizontal transfer device 46.
[0065]
Next, a material transporting method using the material stock apparatus 10 will be described.
[0066]
First, the case where the segments 16 are stocked on the stock shelf 20 disposed in the shaft 14 will be described.
[0067]
With the horizontal transfer device 46 engaged with the ground transfer rail 32 and at the loading position 29 of the segment 16 on the ground 18, the segments 16 are loaded on the receiving table 98 provided on the support table 78 of the horizontal transfer device 46.
[0068]
In this case, it is preferable in terms of transport efficiency that the segments 16 be directly loaded on the horizontal transport device 46 from a truck that transports the segments 16 into the shaft site.
[0069]
Next, the horizontal transport device 46 loaded with the segments 16 is moved on the ground transport rail 32 by the traveling mechanism 62 to transport the segments 16 to a position above the shaft 14.
[0070]
At this time, the lifting / lowering transport device 44 is located at the upper end of the lifting / lowering transport rail 34 and is in a state capable of supporting the horizontal transport device 46. In this state, the horizontal transport device 46 is moved to the vertical transport device 44 side, The transfer from the ground transport rail 32 to the support rail 58 of the lifting / lowering transport device 44 is performed.
[0071]
Here, when the segments 16 are stocked on the uppermost stock shelf 20, the horizontal transport device 46 is moved on the support rail 58 as it is, and is moved onto the horizontal transport rail 36 of the uppermost stock shelf 20. .
[0072]
When stocking the segments 16 on the stock shelf 20 lower than the uppermost stock shelf 20, first, the lock pins 108 of the lock mechanism 104 are inserted into the positioning holes 110 formed in the transfer base 60 of the horizontal transfer device 46. To prevent positioning and falling off. In this state, the vertical transport device 44 is lowered along the vertical transport rail 34 to the target stock shelf 20 position, and the horizontal transport rail 36 of the stock shelf 20 and the height position of the support rail 58 are aligned, The lifting / lowering transport device 44 is stopped. Then, the engagement of the lock pin 108 is released, and the horizontal transport device 46 is moved on the support rail 58 to be moved onto the horizontal transport rail 36 of the target stock shelf 20.
[0073]
Up to this point, the horizontal transfer device 46 has moved onto the horizontal transfer rail 36 of the stock shelf 20. However, the horizontal transfer device 46 moves from the loading position 29 of the segment 16 on the ground 18 onto the horizontal transfer rail 36. In any of the steps up to this point, the support table 78 of the horizontal transfer device 46 is raised by the table lifting / lowering mechanism 66 so that the segment 16 is supported at a position higher than the position of the receiving pin 96 of the material placing table 64.
[0074]
Next, the horizontal transfer device 46 is moved along the horizontal transfer rail 36 from the state in which the horizontal transfer device 46 is moved onto the horizontal transfer rail 36 of the stock shelf 20 to be positioned on both sides of the horizontal transfer rail 36 of the stock shelf 20. The material is conveyed to the material placing table 64, and the support table 78 is inserted between the opposed receiving pins 96 of the material placing table 64.
[0075]
In this state, the segment 16 on the support table 78 is located above the material placing table 64.
[0076]
Next, when the support table 78 is lowered to a position below the receiving pins 96 of the material placing table 64 by the table lifting mechanism 66, the segments 16 abut on the receiving pins 96 of the material placing table 64, and the segments 16 are received. The segments 16 are delivered and left on the pins 96 and are stocked on the material placing table 64.
[0077]
Then, while the support table 78 is lowered, the horizontal transport device 46 is moved along the horizontal transport rail 36 to the lifting / lowering transport device 44 to be moved onto the support rail 58, and the loading of the segments 16 is performed in a reverse process to the above. When the segments 16 are stocked in the material table 64 located at the back of each stock shelf 20 in the same process as described above, the segments 16 are fully loaded on each stock shelf 20. can do.

In addition, since the transfer of the segments 16 to the material table 64 by the horizontal transfer device 46 does not require much height, the stock capacity in the same space can be increased, and efficient stocking becomes possible. This can contribute to space saving. Further, since the horizontal transfer device 46 can be made smaller, it can contribute to cost reduction.
[0079]
Next, a case where the segment 16 is taken out from the stock shelf 20 and transported to the shield tunnel 12 will be described.
[0080]
First, the horizontal transport device 46 that does not support the segment 16 on the support table 78 is supported on the vertical transport device 44 and is at the bottom 30 of the shaft 14, and the vertical transport device 44 is moved along the vertical transport rail 34.

[0082]
At this time, the horizontal transfer device 46 is lowered by the table elevating mechanism 66 and is supported at a position lower than the position of the receiving pin 96 of the material placing table 64.
[0083]
Next, at the stop position relative to the target stock shelf 20, the lock of the lock mechanism 104 is released, and the horizontal transport device 46 is moved from the support rail 58 to the horizontal transport rail 36 by the traveling mechanism 62. The horizontal transporting device 46 is moved along the horizontal direction 36 to move to the material placing table 64 located on the horizontal transporting rail 36 of the stock shelf 20 and to enter between the material placing tables 64.
[0084]
In this state, the support table 78 of the horizontal transfer device 46 is located below the receiving pins 96 of the material placing table 64.
[0085]
Next, the table lifting mechanism 66 raises the support table 78 so that the support table 78 is brought into contact with the lower surface of the segment 16 stocked on the material placing table 64 from between the opposed receiving pins 96 of the material placing table 64 to receive the segment 16. Lift from above the pin 96.
[0086]
Next, the horizontal transport device 46 is moved along the horizontal transport rail 36 while the segments 16 are being lifted by raising the support table 78, so that the segments 16 are taken out from the material table 64.
[0087]
Next, while the segment 16 is taken out from the material placing table 64, the horizontal transport device 46 is moved along the horizontal transport rail 36, and is moved onto the support rail 58 of the elevating transport device 44.
[0088]
In this state, the horizontal transport device 46 is locked by the lock mechanism 104.
[0089]
Next, the vertical transport device 44 is lowered along the vertical transport rail 34 to the bottom 30 of the shaft 14, and the segment 16 may be transferred to the underground transport vehicle (not shown) at the bottom 30 of the shaft 14.
[0090]
In this case, if the same thing as the horizontal transfer rail 36 and the material placing table 64 is prepared in the underground transport vehicle, the segment 16 can be directly transferred to the underground transport vehicle by the horizontal transport device 46.
[0091]
Then, by repeating the above-described steps, the segments 16 may be sequentially taken out from the material placing table 64 located on the front side of each stock shelf 20 and delivered to the underground transport vehicle.
[0092]
As described above, the horizontal transport device 46 is moved to the target stock shelf 20 position, the segment 16 is taken out from the material placing table 64 at the target stock shelf 20 position, and the horizontal transport device 46 from which the segment 16 is taken out is transported vertically. By transporting the segments 16 to the bottom 30 of the shaft 14 by the rails 34 and the lifting / lowering transport device 44, the segments 16 can be efficiently taken out without reloading.
