FIG. 4 shows a front view (a) and a side view (b) of the segment lifting device, respectively.

As shown by these figures, the three-dimensional automatic warehouse of the shield work lining material segment of this embodiment is erected in the starting shaft 1 of the tunnel to be constructed. Into the three-dimensional automatic warehouse 3 (hereinafter, simply referred to as the automatic warehouse 3), a lining material segment A (hereinafter, simply referred to as “segment A”) carried in by a truck on the ground is received by a crane (not shown) (for example, Telha). Then, the transport path 4 connected to the crane is transported by the loading trolley 5 to the entrance 3A of the automatic warehouse 3 and is stocked from the entrance 3A by the elevator 6 attached to the automatic warehouse 3 in the storage shelves installed in multiple stages. It has become.

And a lift 6 having a transporter 6a that can move up and down along the front surface. The multistage storage shelf 3a is a space in which the segments A (generally stacked in two stages) are stored, and a space that is easy to put in and out is secured.
Further, a pair of stands 3b is provided on the shelf at predetermined intervals. Such multi-stage storage shelves 3a are installed on two sides with the moving space of the elevator 6 interposed therebetween.

The lift 6 has a lift set so that the segment A can be handled for each shelf of the multi-stage storage shelf 3a, and is attached to a pair of steel towers 7, 7 standing upright at predetermined intervals. A guide 6a which is guided by a guide rail which can be moved up and down is provided, and the guide 6a is suspended by wire ropes 8a, 8a on both right and left sides, respectively, and is driven synchronously by hoists 8, 8 installed in the shaft 1. It has been made.

A transfer device (not shown) equipped with a fork that can horizontally expand and contract in a direction intersecting with the multi-stage storage shelf 3a is mounted on the transporter 6a of the elevator 6. The fork of the transfer device extends and contracts from the carrier of the transporter 6a into the shelf for storing the segment A of the multi-stage storage shelf 3a, and receives and transfers the segment A between the transporter 6a and the stand 3b in the shelf. It is configured to be able to.

At the place where the transporter 6a of the elevator 6 is lowered to the lower position in operation, an outlet 3B of the automatic warehouse 3 is provided, and a pit is located on the side of the outlet 3B where the transporter 6a reaches. A track 35 of a transport trolley (hereinafter, simply referred to as a transport trolley 30) is extended from the inside of the pit so that the transport trolley can move to the outlet 3B. A retrieval device 10 is installed at an upper portion of the track 35 of the transport vehicle 30 at the retrieval port 3B.

The unloading device 10 comprises a trolley girder 11 having a long span and a traversing carriage 13 (corresponding to a moving body of the present invention) running on the trolley girder 11, and a hoisting machine 15 is mounted on the traversing carriage 13. (This is called Terha).
In this way, a configuration is such that the segments A can be sequentially loaded on the conveyed carriages 30 that are connected to form a single knitted vehicle.

The unloading device 10 is in a state in which the transfer device of the unloading device 6a is operated at the lower stop position of the transporting device 6a at the unloading opening 3B of the automatic warehouse 3 and the fork is extended to the payout side to the maximum. From the transfer position, the trolley girder 11 having a length corresponding to a distance in which the plurality of connected transport vehicles 30 can be received along the track 35 of the transport vehicle 30 to the inside of the mine is moved from the track 35 to the segment lifting device 20. At least two points are supported by the support legs 12, 12 'at a height at which the segment A can be suspended and traveled.

A segment lifting device 20 is suspended from the suspension ropes 15a of the hoisting machine 15 mounted on the traversing carriage 13. This segment lifting device 20 is, for example, as shown in FIGS. 4 (a) and 4 (b), from a drum of a hoisting machine 15, 15 mounted on a traversing carriage 13 which can traverse on a trolley girder 11 (see FIG. 3). The hanging support frames 21 are suspended by the two hanging ropes 15a, 15a via the hanging blocks 15c, 15c attached to the lower ends of the hanging ropes 15a, 15a and the hanging portions 21a, 21a on the upper surface. The segment holding frames 22, 22 which are lowered and are formed in a rectangular shape with a width for receiving the segment A under the hanging support frame 21, are pivotally connected to the hanging support frame 21 at the upper end by pins 22 a, respectively. It is supported and symmetrically suspended at required intervals, and is configured to be opened and closed by linear actuators 25 and 25. The mechanism for operating the segment holding frame 22 is configured such that the base end of each movable rod 25 of the linear actuator 25 supported by the hanging support frame 21 is pin-connected to the upper horizontal member 22b so as to have a predetermined angular range. At the lower intermediate position of the hanging support frame 21,
A hanging limit detecting mechanism 26 and a width restricting mechanism 27 for the segment A are provided, and the detecting mechanisms 26 and 27 prevent the segment A from being hung and prevent a lateral displacement when the segment A is hung. Reference numeral 29 in the figure denotes a steady rest guide.

Further, such a segment lifting device 2
Until the loading operation is started, the traversing truck 13 that suspends 0 is kept waiting at the position B corresponding to the exit 3B of the automatic warehouse 3. Then, at the start of the loading operation, the transfer (lifting) operation from the carrier and the subsequent loading operation to the respective transport vehicles 30 are performed by remote operation or manual operation by an operator.
The loading operation is performed according to a sequentially determined procedure (in the order of the numbers assigned to the segments).

As described above, in the present embodiment, first, the transport vehicle 30 returned to the wellhead for loading is advanced to the inner lower part of the retrieval apparatus 10 and waits. On the other hand, when the segment of the preset address is sequentially sent out to the outlet 3B by the elevator 6 of the automatic warehouse 3 based on the command,
First, the linear actuators 25, 25 of the segment lifting device 20 (traversing trolley 13) waiting at the segment transfer position B are activated to activate the segment holding frames 22, 22.
Is moved outward as indicated by a two-dot chain line a in FIG. 4 (a), so that the segment A on the transporter 6a at the outlet 3B can be scooped.

Next, the hoisting machine 15,
The segment lifting device 20 is driven down to lower the segment lifting device 20 on the transporter 6a, and the segment on the fork in the transfer device is moved to a position where it can be scooped by the open segment holding frames 22, 22. After that, the linear actuators 25, 25 are operated in reverse so that the two segment holding frames 22,
When the turn 22 is turned inward, the segment A is received by being scooped into the inside of the segment holding frames 22, 22. Therefore, by rotating the two segment holding frames 22 and 22 to a predetermined position and stopping and slightly raising the hanging support frame 21, the state shown by a solid line in FIG. 4A is obtained.

The segment A thus lifted from the carriage 6a by the segment lifting device 20 further raises the segment lifting device 20 to the upper limit, and then moves the traversing carriage 13 on the trolley girder 11 to move the segment lifting device 20. It is moved to a position above the transport trolley 30 that is waiting to be loaded, and after stopping at that position, the hoisting machines 15, 15 on the traversing trolley 13 are operated to lower the segment lifting device 20 onto the corresponding transport trolley. After placing the segments transported on the transport trolley, the linear actuators 25, 25 are activated and the segment holding frames 22, 22 are opened outward. Lift the segment lifting device 20 to the next segment receiving position (from the transporter Load receiving position) back to receive segments then unloading in the manner.

Thereafter, the above-described operations are sequentially repeated, so that the segments can be loaded on all the transport vehicles 30... Standing immediately below the retrieval device 10 respectively. When the segments can be loaded onto all the transport vehicles in this manner, one ring of the lining material can be transported from the wellhead to the face by one transport by one connected transport vehicle. Therefore, the lining operation can be performed without causing a waiting time for the assembling operation of the segment by the erector device at the rear of the shield machine.

At the place where the automatic warehouse is installed, if a crane is installed so that the trolley girder of the unloading device is arranged from the outlet of the automatic warehouse toward the inside of the pit, the inside of the pit having sufficient space can be effectively used. A plurality of (for example, six) transport carts are combined into one knitting, and the segments can be loaded in a standby state in the lower portion of the retrieval device 10 in a connected state. During this time, the segment lifting device is moved between the exit port position and each transport truck. The segments are sequentially loaded on the respective transport vehicles by traversing, and there is no need to move the transport vehicles at the time of loading, so that there is an advantage that the loading operation can be performed rationally.

Next, FIG. 5 shows another embodiment of the exit device of the automatic three-dimensional warehouse. Outgoing delivery device 10A of this embodiment
Is basically the same as the device of the above embodiment, but differs in the structure of the moving body. Therefore, the same reference numerals are given to the same or similar parts as in the above-described embodiment, and the detailed description is omitted.

At the lower stop position of the transporter 6a at the exit 3B of the automatic warehouse 3, the moving device of the retrieval device 10A operates the transfer device on the transporter 6a to actuate the fork to the payout side as in the above-described embodiment. In the state of maximum extension, a required distance (at least a plurality of the transport vehicles 30 is connected to the face) along the track 35 of the transport vehicle 30 from the position where the segment A can be received from the transfer device. A traveling rail 47 is laid with a length equal to or longer than the knitting length, and the main body 40 capable of self-traveling on the traveling rail 47 has a bridge-type crane structure.

The main part 40 of the crane structure has a girder 42 at the top by a pair of support legs 41, 41 provided at the lower part with a traveling mechanism 43 capable of self-running on a laid traveling rail 47. The support legs 41 are configured to straddle the track 35 so as not to hinder the movement of the carrier 30. At the center of the upper surface of the girder 42, a hoist 45
Is mounted, and two drums 45a,
The segment lifting device 20 is suspended by two pairs of suspension cables 46, 46 hanging from 45a. The segment lifting device 20 is the same as that in the above embodiment. The traveling mechanism 43 is provided below each of the support legs 41, has two wheels 43a at the front and rear, and is configured to move on the traveling rail 47 by being driven by a reduction motor (not shown).

As described above, in the present embodiment, the transport vehicle 30 returned to the wellhead for loading is advanced to the position of the outlet 3B to be on standby. On the other hand, when the segments that are sequentially carried out from the automatic warehouse 3 to the exit 3B are sent to the transfer position by the transfer device from above the transporter 6a, the segments of the main body 40 that is waiting at the fixed position are moved by the segment lifting device 20. Activate the linear actuator and hold the segment holding frame 2
2 and 22 are opened, and the segment A sent out by the transfer device on the transporter 6a is scooped at the outlet 3B.

After the segments are received by the segment holding frames 22, 22, the hoist 45 is driven to wind up the hoisting rope 46, the segment A is lifted by the segment hoisting device 20, and the deceleration motor of the running mechanism 43 is driven to drive. It is moved to the required position of the carriage 30 waiting on the rail 47 and loaded. By repeating this operation sequentially, the segments can be loaded on the transport carriage 30 knitted by a plurality of units.

In the retrieval apparatus 10A of the present embodiment, the main body 40 is attached to a plurality of transport vehicles which are waiting at the exit 3B along the traveling rail 47 regardless of the number of connected vehicles. By running the vehicle, loading can be sequentially performed, and a fixed device is not used. Therefore, there is an effect that facility costs can be reduced.
