。In addition, the conventional shield excavator is not specially equipped with a segment supply device, and as shown in FIGS. 4 and 5, the segment assembly device erecta-8 tries to grasp The segment 9 is placed directly on the skin plate 3 if the segment 9 has not yet been assembled at the bottom of the excavator (Fig. 4), or on top of the existing segment 9 if it has been assembled. (5th
(Fig.), the gripping screw portion 14 of the erector 8 moves to the position of the gripping screw hole 15 of the segment 9 and grips the segment 9 (Problems to be Solved by the Invention) In the segment supply method, the segment carried by a hoist is simply placed inside the machine, and the position of the segment is not specified, so the erector is manually or automatically moved to the slot for gripping the segment. There is a problem in that the gripping operation requires a long time and the segment assembly time increases. In particular, when attempting to automatically grip a segment, a sensor and a mechanism for finding the gripping screw hole are required, which creates space constraints for installing the sensor and is disadvantageous in terms of cost.

以下添付図面に基づいて、本発明の一実施例を説明する
。Embodiment> An embodiment of the present invention will be described below based on the accompanying drawings.

れる。As shown in FIGS. 1 and 2, at the rear lower part of the main body frame 20 of the shield excavator is a feeder outer cylinder 2 with an open rear end.
1 is attached, and inside this outer cylinder 21, a rectangular cylindrical segment pedestal 22 is attached, and a first hydraulic jack 23 and a guide roller 2
4, it is possible to enter and exit in the longitudinal direction of the excavator. The guide roller 24 is connected to the supply device outer cylinder 21.
Bottom wall 21m and both left and right sides N! 121b in appropriate numbers.

に対応するように、セグメント９を円周方向に調心移動
し得るようになっている。On the upper surface of the segment pedestal 22, a pair of front and rear ball-type sliding floors 25 are installed on both the left and right sides, and a gripping hole 15 provided at the center of gravity (center position) of the segment 9 is installed. The gripping screw portion 14 of the erector 8 (corresponding to FIG. 3) allows the segment 9 to be aligned in the circumferential direction.

うになっている。Furthermore, a plate-shaped front stopper 26 is provided on the segment pedestal 22, and a plate-shaped rear stopper 27 is provided on the supply device outer cylinder 21.
By moving forward the segment pedestal 22 on which the segments 9 are mounted, the segments 9 come into contact with the stoppers 26 and 27 and are positioned in the axial direction.
そして、前記セグメント受台底壁２２ｍの左右方向中間

ジヤツキ２８とテーパはぞ穴３０とでセグメント９の固
定手段が構成されるのである。A second hydraulic jack 28 is erected at the middle part in the left-right direction of the bottom wall 22m of the segment pedestal (this position corresponds to the gripping neck part 14 of the erector 8), and a second hydraulic jack 28 is installed at the tip of the rod. A taper slot 29 attached integrally penetrates the segment holder upper wall 22b by the extension operation of the second hydraulic jack 28, into the taper slot 30 formed in the segment 9 in series with the gripping hole 15. so that they can be fitted together. That is, the tapered slot 29, the second hydraulic jack 28, and the tapered slot 30 constitute a means for fixing the segment 9.
このように構成されるため、先ず図示しないホイストか

伸長作動によりセグメント受台２２が伸びて来て、セグ
メント９をセグメント受台２２に置く。With this structure, when the segment 9 is first carried from a hoist (not shown), the segment pedestal 22 is extended by the extension operation of the first hydraulic jack 23, and the segment 9 is placed on the segment pedestal 22.
この際、ボール式の滑動床２５により、セグメント重心

れるのである。On the other hand, the axial position is defined by both the front and rear stoppers 2627. In other words, when the segment pedestal 22 is moved forward by the contraction operation of the first hydraulic jack 23 with the segment 9 placed thereon, both the front and rear end surfaces of the segment 9 hit the respective stoppers 26 and 27, and the axial position is changed. It is regulated.

自動調心作用が得られる。Then, in order to grasp segment 9 with the erector,
The taper groove 29 is formed by the extension operation of the second hydraulic jack 28.
is fitted into the taper groove 3o to fix the segment 9. At this time, even if the gripping bore 15 is slightly off center, a self-aligning effect can be obtained due to the relationship between the taper groove 29 and the taper groove 3°.
なお、上記実施例にて、固定手段及び滑動床は図示例に
限定されず、本発明の要旨を逸脱しないＩｉ！囲で覆々
の変更が可能であることは言う迄もない。In addition, in the above embodiment, the fixing means and sliding floor are not limited to the illustrated example, and do not depart from the gist of the present invention.Ii! Needless to say, extensive changes can be made within the scope.

、セグメント組立時間が短かくなる。<Effects of the Invention> As explained above, according to the present invention, the segments can be placed at specified positions, so the erector only needs to be moved to the specified position, and the segment gripping hole etc. There is no need to search, the time required for gripping work is shortened, and the segment assembly time is shortened.
特に、自動でセグメントを把持する場合には、把持用ね
