They are symmetrically hung at the required intervals. These segment holding frames 32 are swingable within a predetermined angle range by pin-connecting the ends of the movable rods 35a of the linear actuators 35, 35 whose base ends are supported by the suspension support frame 31 to the upper lateral members 32b. Thus, the hanging limit detection mechanism 36 and the width regulation mechanism 37 of the segment A are provided at the lower middle position of the hanging support frame 31. The hanging limit detection mechanism 3

Reference numeral 39 in the figure is a stopper that regulates the upper limit of lifting of the segment lifting device 30.

The transport system according to the embodiment of the first aspect of the invention constructed as described above has a segment receiving yard 2
In order to start the work in which the transport trailer C of the segment enters the inside of the support leg 16 of the bridge crane 10 at and the transfer of the segment A of the load is started, the bridge crane 10 is operated to operate on the upper girder 11. The traverse frame 14 is moved back and forth by the operation of the traveling mechanism 13 along the traveling rail 12, and the hoisting machine 15 is traversed on the traverse frame 14 by the traverse drive mechanism 15b, and is loaded onto the trailer C. The segment lifting device 30 is aligned with the position of the segment A to lift the target segment A.

The hoisting of the segment A by the segment hoisting device 30 is carried in a state in which a plurality of segments A are preliminarily distinguished and stacked on the loading platform of the trailer C, so that the stacked one block of segment A ( (2 to 3 pieces by weight) are hoisted and received. In the operation of hoisting the segment A by the segment hoisting device 30, first, the linear actuators 35, 35 attached to the hoisting support frame 31 are actuated to project their movable rods 35a.
As shown by the chain double-dashed line a in FIG. 6A, 32 is widened from the pins 32a, 32a as a base point, and its tip end is wider than both outer ends of the stacked segment A. .

Therefore, the hoisting machine 15 is operated to lower the hanging support frame 31 to correspond to the segment A hoisted on the loading platform of the trailer C, and the linear actuators 35,
When the movable rod 35a is retracted by reversely operating 35,
The segment holding frames 32, 32 are turned inward and are received by scooping the target segment A to be hung inside from both outsides. Therefore, by rotating both segment holding frames 32 to a predetermined position and slightly raising the suspension support frame 31 after stopping, the two segment holding frames 32 move as shown by the solid line in FIG. 6A. Thus, the stacked segments A can be lifted. The segment hoisting device 30 hoisting the segment A as described above is held in a travelable state by the stopper 39 when the hoisting machine 15 hoists the hoisting ropes 15a, 15a to the uppermost position.

The segment A hoisted by the segment hoisting device 30 in this manner is held in a traveling state, and the traverse frame 14 is traversed to cause the carriage 11 to project at the portion where the girder 11 projects toward the segment conveyor path 6 side. Be moved to the unloading position.

On the other hand, in the traverser 20 provided at the position near the bridge crane 10 on the segment transport path 6, one of the transport bases 21 is made to match the track 6a attached to the segment transport path 6. The empty carriage 7 is mounted on the carriage 21 and is on standby. In this state, the lifted segment A is moved by the traveling of the traverse frame 14 in the bridge crane 10, and the segment lifting device 30 is just waiting for the transport carriage 7
When it reaches the top and is unloaded, it is supported on the segment support base 7'provided on the carrier 7.

When the segment A held by the segment lifting device 30 is received on the segment support base 7'of the transport carriage 7, the linear actuator 35 of the segment lifting device 30 is operated to move the segment holding frame 32. By operating in the opening direction, the segment A operates in a manner opposite to the lifting operation of the segment A, and is separated from the segment A held by the segment holding frames 32, 32, so that the hoisting machine 15 winds the hoist rope 15a. When the segment lifting device 30 is lifted by performing a picking operation, the operation of transferring the segment A to the transport carriage 7 is completed. The segment hoisting device 30, which has transferred the segment A to the transport carriage 7, is lifted to the uppermost position to return the traverse frame 14 to the original position, and shifts to a position to hoist the next receiving segment on the trailer C.

Received (mounted) segment A
In the traverser 20, the carrier vehicle 7 is a carrier vehicle 7 that is different from the other carrier vehicle 7 previously mounted on the other carrier table 21.
The bridge crane 10 is moved to the unloading position of the above-mentioned segment A to receive and stand by. During this preparation period, the segment A is hoisted and carried out from the trailer C by the segment hoisting device 30 in the above-described manner.
However, when the segment A is moved onto the waiting transport carriage 7, the segment lifting device 30 is lowered in the above manner, the segment holding frames 32, 32 of the segment lifting device 30 are opened, and the transported segment A is transported by the transport carrier. 7 is transferred onto the segment support base 7 '.

In this way, if the transported segment A is mounted on each of the transport carriages 7 mounted on the two transport carriages 21 of the traverser 20, one of the transport carriages 7 on one of the transport carriages 21 is loaded. A transfer device (not shown) that is mounted by moving the vertical transport device 4 to the transfer position of the vertical transport device 4 to the transfer device 4a and mounting the transfer device 4a on the floor at the transfer position is moved. The segment A is moved from the transport carriage 7 to the transporter 4a and loaded into the required storage rack of the stock rack 5 by being operated. In this way, while one transport carriage 7 moves to the transfer position on the vertical transport device 4, the drive mechanism 23 is operated to move the remaining transport platform 21 to the position (unloading position) that matches the segment transport path 6. To move. After that, the carrier truck 7 waiting on the track of the segment carrier path 6 is moved from the carrier table 21,
The vehicle is moved to the transfer position on the vertical transport device 4.

After transferring the segment A conveyed at the transfer position to the vertical transfer device 4 to the carrier 4a, the transfer carriage 7 is temporarily moved from the transfer position to the position of the tip end of the segment transfer path 6. The next transfer carriage 7 waits until the work of transferring the segment A transferred to the vertical transfer device 4 side at the transfer position is completed. In this way, when the two carrier vehicles 7 complete the carrying operation, the traverser 20
The carriage 7 is returned to the carriage 21 position (unloading position), and the carriage 7 carrying the segment A later is first mounted on the carriage 21 and is lifted and moved by the bridge crane 10 in the above-described procedure at the receiving position. New segment A
The operation of transferring is performed. Then, the carrier truck 7 loaded with the segment A has the traverser 2 as described above.
The drive mechanism 23 of 0 is operated to move it from the loading position (unloading position of the bridge crane) to the standby position, and another transport platform 21 is loaded with the transport vehicle 7 waiting on the segment transport path 6 to newly install it. The operation of loading different segments A is repeated. After that, the segment A received from the trailer C is sequentially carried out by such a procedure, carried into the storage rack of the stock rack 5 via the vertical carrying device 4, and stored. In addition, segment A for the carriage 7
The loading order of the
The one mounted above is moved, the segment A is mounted on the one to be mounted on another carrier 21 later, and the segment A is transferred to the empty carrier truck 7 which has been sent out after being carried out.
The operations may be performed in any order such as loading the items.

Traverse frame 1 in bridge crane 10
The hoisting machine 15 mounted on the No. 4 can be traversed between the two parallel girders 11 and 11 by the traverse drive mechanism 15b, and therefore corresponds to the segment A loaded side by side on the cargo bed of the trailer C. Then, the segment hoisting device 30 is moved laterally to operate the segment hoisting device 30 at the position directly above, so that it is possible to work safely without performing an unreasonable operation such as diagonal pulling.

According to the first aspect of the invention configured and operated in this manner, since it functions as described above, a plurality of transport carriages 7 (two transport carriages in this specific example) are connected to one transport path. The traveling operation is performed on the track, and the cargo receiving work from the transportation vehicle (trailer C) of the segment A by the bridge crane 10 which is the cargo receiving equipment and the operation cycle of the carrier truck 7 that carries the received segment A into the stock rack 5 are performed. By engaging well, you can eliminate temporary stock on the ground in a short time and directly accept from the transportation vehicle to the stock rack, and pre-program these operations to automate the operation of each part As a result, it can be operated by a small number of workers and can be rationalized. In addition, if the number of the carriages 21 in the traverser 20 is further increased so that three carriages can be operated, the efficiency can be further improved.

In order to start the work in which the transport trailer C of the segment enters the inside of the support leg 16 of the bridge crane 10B in and the delivery of the segment A of the load is started, the bridge crane 10B is driven to move along the trolley rail 12a. The carrier 13a is moved back and forth, and the target segment A is lifted by aligning the segment lifting device 30 with the position of the segment A loaded on the trailer C.
Such an operation is performed in the same manner as in the above-mentioned embodiment.

When the segment A is lifted by the segment lifting device 30 by the operation of the hoisting rope 15d by the hoist 15A, the carrier 13a is allowed to travel to the unloading position as it is, and is made to stand by at the unloading position in advance. Each segment support base 7'of the carrier 7A
The segment lifting device 30 is lowered at a position corresponding to (each of the transport carriages 7a to be connected), and the segment A held in the above manner is lowered onto the segment support base 7'of the transport carriage 7A and transferred. In carrying out this operation, in this embodiment, two transport carriages 7A on the segment transport path 6 are connected to each other, so that the unloading of the segment A onto the transport carriage 7A is performed by each of them. The position of the carrier 13a (segment hoisting device 30) is moved on the girder 11a protruding to the position corresponding to the transport carriage 7a so that the carrier 13a (segment hoisting device 30) can be moved to the corresponding position, and the vertical movement is performed after continuously unloading and transferring them. The transport carriage 7A is moved to the transfer position on the transport device 4 to carry it into the stock rack 5. In addition, within the time until the transport vehicle 7A transports the segment A to the transfer position on the vertical transport device 4 and returns, the hoisting operation of the segment A to be transported next can be performed and it can wait at the unloading position. To

In this embodiment, the bridge crane 10B is constructed by transporting the segment A by two blocks at a time by the operation of the transport carriage 7A.
It is possible to reduce the round-trip time required for the transport carriage 7A to transport the segment A, which has been received in the above, to the transfer position to the vertical transport device 4 and to return it, compared to transporting it one block at a time. The efficiency of the receiving work to the rack 5 can be improved.

As described above, in any of the first to third inventions, since each drive unit can be automatically controlled, its driving operation can be performed remotely based on a preset program. By making it possible to sequentially operate by operation, it becomes possible to carry out the receiving work by operating with a minimum number of people, which was conventionally done by many workers operating each part and receiving the segment. It is possible to eliminate the storage space for the lining material in the section and to rationalize the operation of supplying the lining material.

The segment conveying path 6 in this embodiment is the conveying path for the lining material in the present invention (first invention), the segment lifting device 30 is the lining material lifting device, the hoisting machine is the hoisting drive mechanism, and Frame 14 (14A) is a horizontal beam,
Corresponds to each.
