Further, a plurality of shield jacks 105 are mounted in the circumferential direction at the rear end portion of the shield excavator main body 102, and the shield jacks 105 extend rearward in the excavating direction of the shield excavator to thereby excavate inside the tunnel. The shield excavator main body 102 is moved forward while being pressed against the existing segment 106 constructed on the peripheral surface. Then, the segment 106 is attached by a segment elector device (not shown). A chamber 107 is formed behind the cutter device 103, and a screw conveyor 108 is formed in the chamber 107.
Are connected.

A sleeper 109 is laid inside the tunnel mine constructed by excavating and assembling the segments 106. On this sleeper 109, two rails 110 for trailing trucks are provided on one side of the tunnel and one rail on the other side. The rail 111 is laid. Further, two rails 112 for a carrier truck are laid between the rails 110 and 111 for the following truck. Further, a trailing equipment carriage 113 towed by the shield excavator main body 102 can travel on the rails 110 and 111, and a belt conveyor 114 is mounted on the trailing equipment carriage 113. On the other hand, a transport carriage 115 is freely movable on the rail 112, and the transport carriage 115 includes segments 106, sleepers 109, and rails 11.
0, 111, 112 can be mounted. Further, a conveyor 116 on which the segment 106 is placed is arranged in front of each rail 110, 111, 112.

In order to excavate and form a tunnel, first, the shield excavator main body 102 is moved forward while operating the plurality of shield jacks 105 in the extension direction and pressing them against the front side of the existing segment 106. The cutter device 103 is rotated by the drive motor 104. And
The rock mass in front of the shield excavator main body 102 is excavated, and the excavated earth and sand is dropped into the chamber 107. Next, one of the plurality of shield jacks 105 is operated in the contracting direction to form a space between the existing segment 106 and
New segment 10 by segment erector device
Install 6 in this space. On the other hand, the excavated earth and sand in the chamber 20 is conveyed backward by the screw conveyor 108, and is discharged to the outside of the mine by the earth discharging and discharging carriage (not shown) via the belt conveyor 114.

During this operation, the carrier 115 having the segment 106 mounted thereon moves forward along the rail 112 to supply the segment 106, and the conveyor 11 is driven by a hoist (not shown) arranged at the front of the succeeding equipment carrier 113.

In the above-described conventional transfer and installation apparatus for a shield excavator, the segment 106 to be assembled is curved in an arc shape in the tunnel excavation work, and although the segment 106 has a narrow width, the segment 106 has a curved direction. Since the length is sufficiently long, the longitudinal direction of the segment 106 should be mounted on the transport carriage 115 along the traveling direction so that the transport carriage 115 carrying the segment 106 can pass inside the succeeding equipment carriage 113. Becomes However, when the segment 106 is mounted on the inner wall surface of the tunnel, the longitudinal direction of the segment 106 is mounted along the circumferential direction of the tunnel. Therefore, when the segment 106 is transferred from the transport carriage 115 to the conveyor 116, the
You have to rotate it 0 degrees. In addition, sleepers 109 and rails 110, 111, which are required for tunnel excavation,
For the same reason, 112 also has to be rotated 90 degrees by a hoist before laying.

However, the constructed tunnel is a narrow space, and the hoist is used to connect the segment 106 and the sleeper 10 to each other.
9, it is difficult to lift and rotate the rails 110, 111, 112 and the like, and the work takes a long time, and such work is very dangerous for the operator. Further, the screw conveyor 108 and the belt conveyor 114 are arranged in the working space,
For long objects such as rails 110, 111, 112,
The hoist may not reach, and in this case, the operator has to do it manually, the number of rails to carry is very large, and the feet are also slippery, which puts a heavy physical burden on the operator. It was not preferable in terms of safety.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a transfer installation device for a shield excavator, which improves workability and safety.
