Claims

[Claims for Utility Model Registration] A support beam is disposed on a swing ring that can rotate along the inner circumferential wall of the shield frame so as to be movable in the radial direction, and a segment gripping device is installed in the center of the support beam. In a segment assembly device for a tunnel excavator protruding outward, the segment gripping device is rotated around a circle of the shield frame with the center of gravity of the segment gripped by the support beam or the vicinity thereof as the center of rotation. 1. A segment assembly device for a tunnel excavator, characterized in that the segment assembly device is arranged to be swingable in the circumferential direction and in a direction perpendicular to the circumferential direction, and is provided with drive devices for swinging the segment gripping device in each of the directions.
