Claims

[Scope of utility model registration request]

In a shield excavator in which a swivel ring is rotatably supported by a roller inside a skin plate at the rear of the shield excavator, the sliding block is supported so as to be movable in the axial direction by a sliding guide rod that projects rearward from the swivel ring. At the same time, a sliding jack is interposed between the sliding block and the swivel ring, and the sliding block supports the transverse guide rod in a lateral direction perpendicular to the axial direction. An erector device for a shield excavator, characterized in that a traversing jack is interposed between the sliding block and the traversing jack, the traversing guide rod, and a segment grip device are connected via an arm.
