Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the main body 2 of the box-type shield machine 1 has a rectangular cross section, and has an erector device 3 therein as shown in FIGS.

The erector device 3 mainly comprises a linear motion bearing 8, a traversing frame 4, and a lateral moving jack 7.
, A rotating bearing 15 with gears, a rotating frame 5,
It comprises a segment holding device 29, a link mechanism 30, a segment holding device lifting / lowering jack 6, and a corner segment adapter 20. The traversing frame 4 has an annular shape and is movable in the lateral direction of the main body 2. That is, the traversing frame 4 includes the linear motion bearing 8.
It is slidably attached to a pair of upper and lower guide rails 10 and 11 which are attached to the partition 9 of the main body 2 in the lateral direction.

The transverse frame 4 and the side wall 2a of the main body
The lateral movement jack, that is, the fluid pressure cylinder 7 is disposed between the rod 13 and the main body side wall 2a so as to swing freely.
Is pivotally supported by a frame body 14 attached to the frame. When the rod 12 is extended, the traversing frame 4 is moved to the position shown in FIG.
When the rod 12 contracts, the traversing frame 4 moves toward the right side in FIG. In addition,
The jack for lateral movement may use an electric screw type cylinder instead of the fluid pressure cylinder.

On the back surface of the traversing frame 4, an annular rotating frame 5 is arranged in parallel via a rotating bearing 15 with internal teeth. When the pinion 17 meshing with the internal teeth 16 of the slewing bearing 15 rotates forward and reverse by the forward and reverse rotation motor 18 installed on the traversing frame 4, the rotating frame 5 rotates clockwise or counterclockwise. It is supposed to.

Further, as shown in FIGS. 3 and 4, the back surface of the rotating frame 5 and the segment holding device 29 are connected by a link mechanism 30. This link mechanism 30
Are provided on both sides of the lifting jack 6 as shown in FIG. 4, and each of them is connected to the one-shaped first link 31 on the upper side and to the lower side as shown in FIG. 3. It is constituted by a second link 32 having a character shape. Then, the lifting / lowering jack 6 is pivotally supported on the bent portion 32 a of the second link 32 via a support shaft 34 provided on the cylinder portion 33, and a bracket 36 in which the end of the rod 35 is fixed to the rotating frame 5. It is pivoted to.

As shown in FIG. 5, when the corner segments are assembled, the corner segment adapter 20 is used.
Is attached to the segment gripping device 29. The adapter 20 is composed of a corner segment mounting bracket 22 mounted on the lower surface of the base 21 and two brackets 23, 24 mounted on the upper surface of the base 21. The back of the two brackets 23, 24, one of the brackets 23 is provided. To the support shaft 25 of the segment gripper 29.
, And the other bracket 24 is pinned to the bracket 26 of the segment gripping device 29.

Although FIG. 5 shows the case where the adapter 20 is mounted on the left end of the support shaft 25, when assembling the opposite corner segment, the adapter 20 is mounted on the right end of the support shaft 25. Also, in FIG.
Numeral 7 denotes a mud pipe, and 28 denotes a mud pipe. Next, the segment assembling operation will be described.

[0012] As shown in FIG.
Corner segment S1 on the adapter 20 mounted on
After attaching the traverse frame (not shown) to the mud pipe 27
The adapter 20 is moved to the left side of the main body 2 so as not to interfere with the exhaust pipe 28, and the rotating frame 5 is further rotated clockwise so that the adapter 20 faces the lower left corner portion R1. Then, the segment gripping device 29 is lowered toward the corner R1, and the corner segment S1 is assembled to the lower left corner R1.

Next, a segment S2 is assembled to the right of the corner segment S1. This assembling operation is performed by the segment gripping device 29 from which the adapter 20 has been removed. Again, the adapter 20 is attached to the segment holding device 29, and the corner segment S3 is attached to the lower right corner R2.

Next, as shown in FIG. 7, a segment S4 is assembled between the segment S3 and the lower right corner segment S2. This assembly is performed by the segment gripping device 29 from which the adapter 20 has been removed. Next, as shown in FIG. 8, the lower right corner segment S3
The segment S5 is assembled on the upper side of the. At this time, after attaching the segment S5 to the segment gripping device 29, the rotating frame 5 is rotated counterclockwise by 90 °, and further, the transverse frame 4 is sent to the right side so as not to interfere with the sludge pipes 27 and 28. And then the segment gripper 2
9 is shifted to the right, and the segment S5 is assembled.

Next, as shown in FIG. 9, a segment S6 is assembled on the lower left corner segment S1. At this time, after attaching the segment S6 to the segment gripping device 29, the rotating frame 5 is rotated clockwise by 90 °. Then, a traversing frame (not shown) is sent,
The segment gripper 29 is moved to the left so as not to interfere with the segments 7, 28, and then the segment S6 is assembled by moving the segment gripping device 29 to the left.

Next, as shown in FIG. 10, segments S7 and S8 are attached to the left and upper right corners R3 and R4. When assembling the segment S7 to the upper left corner R3, after attaching the segment S7 to the adapter 20 attached to the segment gripping device 29, the rotating frame 5 is rotated clockwise to place the adapter 20 at the upper left corner R3. Point. After moving the segment gripping device 29 toward the upper left corner R3, the horizontal frame (not shown) is moved to the left to assemble.

When assembling the segment S8 at the upper right corner R4, the segment S8 is attached to the adapter 20 attached to the segment holding device 29,
Rotate the rotating frame 5 counterclockwise to remove the adapter 2
0 is directed to the upper right corner R4. Then, after moving the segment gripping device 29 toward the upper right corner R4, the traversing frame 4 is moved to the right to assemble.

Next, as shown in FIG. 11, a segment S9 is assembled on the left side of the segment S8 in the upper right corner. At this time, after attaching the segment S9 to the segment gripping device 29, the rotating frame 5 is rotated clockwise by 180 degrees.
Rotate °. Then, the traversing frame 4 is moved to the right so as not to interfere with the feeding and discharging pipes 27 and 28, and thereafter, the segment holding device 29 is moved upward to assemble.

Finally, as shown in FIG. 12, a segment S10 is assembled between the upper left corner segment S7 and the segment S9. At this time, after attaching the segment S10 to the segment gripping device 29, the rotating frame 5 is rotated clockwise by 180 °. And send,
The traversing frame (not shown) is moved to the left so as not to interfere with the sludge pipes 27 and 28, and then the segment holding device 29 is moved upward to assemble.

In the above description, the case where the segments are assembled into a rectangular cross section is described. However, it is needless to say that the present invention can be applied to the case where the segments are assembled into a square cross section.

[0021]

As described above, according to the present invention, an excavator main body is provided with an annular traversing frame traversably disposed via a linear motion bearing and a jack for lateral movement between the main body and the annular traverse frame. An end face of an annular rotating frame juxtaposed to the traverse frame via a geared slewing bearing is connected to a segment gripping device by a link mechanism, and a segment gripping device lifting jack is provided between the rotating frame and the link mechanism. Is arranged, and since the segment segment adapter is provided detachably on the segment gripping device,
The segments can be assembled in a box shape, particularly a rectangular shape, without the erector device, particularly the traversing frame or the rotating frame that constitutes the erector device interfering with the mud pipe or the mud pipe.

Further, since the rotating frame and the segment holding device are connected by a link mechanism and the link mechanism is moved up and down by a lifting jack pivotally supported by the rotating frame, the lifting device for the segment holding device can be made compact. We were able to.
