A jack 25 is provided, and the lower end of each clamp jack 25 is connected to the pin 2
As shown in FIG. 13, it is mounted in a reverse C shape by a pin 26 which is parallel to the pin 4. When the clamp jack 25 is expanded and contracted, the grip blocks 20 and 20 are relatively moved toward and away from each other along the guide member 20a so that the grip hardware 19 can be clamped and unclamped.

In addition, front and rear clamp jacks 25, 2 provided on the left and right side portions of the sliding guide block 15.
As shown in FIG. 13, vertically downward pressing jacks 27, 27 are provided at the intermediate position of 5, and the lower end of the piston of each pressing jack 27, 27 is matched with the inner surface shape of the segment 18. The pressure pads 28, 28 are attached. The pressing jacks 27, 27 can be separately expanded and contracted. Therefore, by changing the pressing force of the pressing pads 28, 28 to the segment 18 from side to side, the inclination (rolling) in the circumferential direction with respect to the inner surface of the tunnel is adjusted. Is able to. Also,
The inclination (pitching) of the segment 18 with respect to the axis of the rotating frame 1 is regulated by the length of the pressing pads 28, 28 in the front-rear direction.

As shown in FIGS. 15 and 16, the segment 18 used in the segment assembling apparatus shown in FIGS. 11 to 14 has an arc shape with a narrow width dimension, and the inside center of the arc shape has the above-mentioned shape. A gripping piece 19 is provided, and a sealing material 29 such as rubber is attached to the end faces in the width direction and the circumferential direction. Further, a bolt is fastened to the inner surface of the segment 18 at a position close to the end faces in the width direction and the circumferential direction. The bolt box hole 30 having the bolt hole 30a of FIG.
The segment 18 shown in FIG. 16 is usually called a flat plate segment.

The flat plate segment 18 is shown in FIG. 11 and FIG.
In the rear cylinder 2 of the shield machine, as shown in FIG. 2, a plurality of bolts are fastened by bolts to assemble them in a ring shape. For this reason, the segment 18 is usually divided by a radial straight line passing through the center. The end face in the circumferential direction has a wedge shape with a wedge shape.

However, if all the segments 18 are fan-shaped in this way, the final segment cannot be pushed in from the inside to be assembled.

Therefore, the case where the final segment is moved in the axial direction to be assembled will be described as an example. As shown in FIG. 17, a part of the ring assembled by the normal fan-shaped segment 18a has a special shape. It has one final segment 18b and two side segments 18b 'arranged on both sides of the final segment 18b.

The final segment 18b is shown in FIGS.
As shown in FIG. 3, the end face in the circumferential direction has a fan shape with an angle smaller than the fan shape of the segment 18a, and the length of the front side (shield excavator side) is also front and rear (axial direction of the rotating frame 1). It has a long taper shape and a short rear side. Also, the final segment 1 of the side segment 18b '
The end surface adjacent to 8b is a tapered surface that matches the taper of the final segment 18b.

The assembly of the final segment 18b as described above is carried out by the normal segment 18a and the side segment 1
After assembling 8b ', the final segment 18b is first moved forward from the assembled segment, then extended outward, and then moved backward as shown by the arrow in FIG. ing.

Further, as described above, the final segment 18
In contrast to the method of assembling b from the axial direction, a method of assembling by pushing the final segment from the inner side to the outer side in the radial direction is also performed as in the case of the normal segment 18a. In contrast to the fan shape, the tip is narrowed toward the outside.

The segment 18 is conveyed from the rear by a hoist (not shown) or the like and placed on the bottom of the segment 18 which has already been assembled in a ring shape. In the segment assembling apparatus shown in FIGS. Rotating frame 1
Is rotated to rotate the suspension beam 9, and the fluid pressure cylinder 16 is expanded / contracted to move the sliding guide block 15 back and forth, thereby gripping the center of rotation of the rotary frame 1 and the segment 18 to be gripped. The metal cylinder 19 and the sliding guide block 15 are positioned so that they are aligned with each other, and the clamp jacks 25 are simultaneously reduced so that the grip blocks 20, 20 are separated from each other, and the fluid pressure cylinder 11 is extended. By doing so, the outer surface (lower surface) of the gripping blocks 20, 20 is the segment 1
Adjust so that it is closer to the inner surface of 8.

Subsequently, the clamp jacks 25 are simultaneously extended and slid so that the grip blocks 20 and 20 come close to each other, and the opposing surfaces of the grip blocks 20 and 20 are brought into contact with each other as shown by the solid line in FIG. Let As a result, the holding metal piece 19 of the segment 18 is held by the clamp holes 22 of the holding blocks 20, 20.

Subsequently, the pressing jacks 27, 27 are extended to press the pressing pads 28, 28 against the inner surface of the segment 18 to suppress the wobbling of the pitching of the segment 18, and the rolling is adjusted. When the cylinder 11 is contracted, the segment 18 can be lifted. The hoisted segment 18 moves to a predetermined fastening position by the rotation of the rotary frame 1, the lifting and lowering of the hoisting beam 9 by the expansion and contraction of the fluid pressure cylinder 11, and the back and forth movement of the sliding guide block 15 by the expansion and contraction of the fluid pressure cylinder 16. Then, the existing segment 18 is bolted.

The fan-shaped final segment 18 shown in FIG.
When assembling b, the final segment 18b is first moved forward from the assembled segment, then outwardly projected, and then moved rearward as shown by the arrow in FIG. Further, when assembling the final segment having a shape in which the tip becomes narrower toward the outside, it is pushed in from the inside toward the outside in the radial direction like the ordinary segment 18a.

[0031]

However, the above-mentioned FIG.
The conventional segment assembling apparatus shown in FIGS. 14, 22, and 23 has various problems because yawing (the direction in which the gripped segments 18 and 31 are horizontally swung) cannot be adjusted.

In other words, in the segment assembling apparatus shown in FIGS. 11 to 14, the segment 18 placed on the existing segment 18 is displaced in the turning direction (the front end face of the existing segment 18 and the front end face of the existing segment 18 will be assembled). Even if the front and rear end surfaces of the segment 18 are not parallel to each other, the gripping hardware 19 is gripped as it is, and the pressing pad 28 presses the inner surface to lift the segment 18 in a restrained state.

For this reason, when the segment 18 is moved in the horizontal direction and is positioned by moving the segment 18 to the fastening position, the corner of the grasped segment 18 cannot be adjusted because the yaw cannot be adjusted. 18, the corner is chipped off, or the sealing material 29 is collided by the collision.
May be damaged, and in this case, the sealability of the assembled segment 18 cannot be ensured and there is a problem that repair work needs to be performed. If the final segment 18b is largely displaced in the turning direction at the time of assembling, the final segment 1 is located between the side segments 18b 'and 18b'.
In some cases, 8b could not be inserted.

Further, in the segment assembling apparatus shown in FIGS. 22 and 23, the four gripping pins 36 are inserted into the bolt holes 35 provided in the recess 32 of the segment 31 and gripped so that the four pins are restrained at four points. Therefore, when the gripping pin 36 is gripped, if the segment 31 placed on the existing segment 31 is largely deviated in the turning direction, the gripping pin 36 is not likely to be displaced in the turning direction. Even if it is projected, it cannot be inserted into the bolt hole 35, so that the segment 31 cannot be gripped. Also in the case of the apparatus of FIGS. 22 and 23, when the segment 31 is grasped in a state of being displaced in the turning direction, a collision occurs when the existing segment 31 is positioned in the same manner as described above. , The corner is chipped or the sealing material 2
9 creates the problem of damage.

Further, in FIGS. 11 to 14 and FIG.
In the conventional segment assembling apparatus shown in FIG. 23, when the curved construction of the tunnel is carried out, or when the tail clearance of the shield machine is biased, the existing segment and the shaft of the shield machine (sliding of the segment machine are removed). In some cases, the sliding direction of the motion guide block 15 does not match. In this case, when the final segment 18b is moved in the axial direction to be inserted between the existing side segments 18b 'and 18b', Due to the deviation of the turning direction, there arises a problem that the insertion cannot be performed or the corners are chipped, and in the case of the core type segment 31 as shown in FIGS. 20 and 21, the gripping is caused due to the deviation of the turning direction. There is a problem that you can not.

The present invention has been made in view of such an actual situation. Even if the segment held by the segment assembling device is displaced in the turning direction, the segment is aligned with the existing segment so that the corner of the segment can be aligned at the time of positioning. It is an object of the present invention to provide a segment assembling device for a shield machine, which prevents a problem such as a collision of parts, and facilitates and surely holds a segment.
