A left traverse truck 46A for loading ready-mixed concrete.
The holding cylinder 44A is fixed to the bogie frame 51 via a pair of front and rear horizontal fixed shafts 56 in an upright posture, and the holding cylinder 44A is inserted into the upper opening 7 and the raw concrete supply position (delivery position) A on the side thereof. Can be moved back and forth between The same members are denoted by the same reference numerals, and description thereof will be omitted.

In the holding cylinders 44A and 44B, the transport container 4
As shown in FIGS. 11 to 13, the container holder 47 for fixing the plurality of capsule receivers 61 disposed at symmetric positions at the lower ends of the holding cylinders 44A and 44B, and the holding cylinders 44A and 4B.
5B and a clamp member 62 arranged at a symmetrical position in the middle part of 5B. The capsule receiving member 61 is configured to protrude the receiving plate 61b below the transport container 4 by the retractable cylinder 61a to support the transport container 4 from below. Further, the clamp member 62 includes a clamp cylinder 62a.
Thus, the clamp block 62b is configured to be pressed against the body of the container body 11 and clamped.

Therefore, after the transport container 4 to be moved upward is slightly raised from the holding cylinders 45A and 45B and stopped, the receiving cylinder 62a of the capsule receiving tool 61 causes the receiving plate 62b to protrude, thereby driving air. The transport container 4 is lowered by reducing the negative pressure from the unit 8, and the receiving plate 62
After the transport container 4 lands on the container b, the clamp block 62b is pressed against and held by the clamp cylinder 62a of the clamp tool 62 against the body of the container body 11, so that the transport container 4 is fixed within the holding cylinders 44A and 44B. Can be fixed in position.

In the above configuration, when the ready-mixed concrete is to be carried into the bottom of the shaft 1, the left traverse truck 46 for loading the ready-mixed concrete is used.
A, the ready-mixed concrete supply position A by the left-hand trolley 46A
The ready-mixed concrete is put into the transport container 45A that has been moved to. Then, the left traversing carriage 46A is moved to move the transport container 4 from the ready-mixed concrete supply position to the upper access port 5, and the holding cylinder 44A is moved.
Is fitted into the notch 42. Then, the inside of the upper cylinder 41 is operated to a predetermined negative pressure by the driving air unit 8 to open the clamp member 62 and the capsule receiving member 61 to release the transport container 4.
In the free state, the transport container 4 is lowered along the guide casing 3 at a predetermined speed.

When the transport container 4 reaches the lower access port 5 and is placed on the receiving frame 34 of the capsule insertion / removal device 6, the guide casing 3 is driven by the driving air unit 8.
The pressure inside the container is returned to the atmospheric pressure, the receiving frame 34 is further lowered to the lower limit by the loading / unloading cylinder 33, and the transport container 4 is removed from the lower loading / unloading port 5. This transport container 4
Is transported by a hoist or the like. The empty transport container 4 from which the ready-mixed concrete has been discharged is transferred to the upper entrance 7 in the reverse order.

When transporting the debris, the debris is put into the transport container 4 on the receiving frame 34 lowered to the lower limit by the loading / unloading cylinder 33 of the capsule insertion / removal device 6. When the transfer container 4 is fitted into the lower access port 5 by the access cylinder 33 via the receiving frame 34, the guide casing 3 is driven by the drive air unit 8.
The inside is brought into a predetermined negative pressure state, whereby the transport container 4 is moved up.

The transfer container 4 is provided with the holding cylinder 4 at the upper access port 7.
4B, the cylinder is raised slightly upward from the holding cylinder 44B, and stopped.
As a result, the receiving plate 62b is protruded, the negative pressure from the driving air unit 8 is slightly approached to the atmospheric pressure, the transport container 4 is lowered, and the transport container 4 is landed on the receiving plate 62b. Then, the container body 11 is held by the clamp member 62. Then, when the inside of the upper cylinder 41 is returned to the atmospheric pressure, the traversing carriage 46B is moved rightward in the figure by the traversing drive device 54, and the transport container 4 is moved from the upper access port 7 to the shear discharge position. Further, the holding tube 44B is rotated to the right by θ degrees from the upright position to the discharging position by the container reversing mechanism 55, and the slip in the transport container 4 held by the holding tube 44B is discharged to a receiving device such as a slip hopper. . After the empty transport container 4 is returned to the upright posture, it is returned from the shear discharge position to the upper access port 7, and is transferred to the lower access port 5 in the reverse order.

According to the above-mentioned embodiment, the new casing piece 3 _{n + 1} can be connected to the existing casing piece 3 _n by using the capsule insertion / removal device 6 for taking the transport container 4 in and out of the lower access port 5. since it, lifting devices for connecting lifting the casing piece 3 _b ~3 n + ₁ which is a heavy object becomes unnecessary, it is possible to simplify the facilities for extension.

Further the movable ring 31 detachable to the casing piece 3 _b ~3 n + ₁ by the ring fixture 32, and out cylinder 33 for vertically moving the movable ring 31
Accordingly, the capsule insertion / removal device 6 can be easily lowered following the extension of the guide casing 3, and the extension operation of the guide casing 3 can be performed smoothly.

Further, the drive air unit 8 is connected to the upper end of the guide casing 3 via the suction duct 19, and the space above the transfer container 4 is made negative pressure, so that the transfer container 4 is moved up and down. It is only necessary to open the lower access port 5 of the guide casing 3 and / or the atmosphere opening port 34a of the receiving frame 34 to the atmosphere side, so that an auxiliary device such as an air duct is not required along the guide casing 3 and the equipment can be simplified. Thus, the guide casing 3 can be easily extended.

In the above-described embodiment, the access port 7 provided with the capsule insertion / removal device 6 is provided only at the upper portion. However, the access port 7 may be provided at the upper portion of the guide casing 3 in two upper and lower stages. It can also be provided in the middle part of the casing 3.
