置におけるセグメント把持装置。 The drive shaft has a gripping male threaded portion at its tip that can be freely inserted into the gripping female threaded portion formed on the segment.
A support cylinder that is movably supported only in the axial direction is provided so as to be movable in and out of the casing that opens in the gripping frame, and is attached to the drive shaft between the gripping male threaded part and the support cylinder in the axial direction. At the same time, the extrusion threaded tube formed on the outer periphery of the extrusion screw tube is engaged with the extrusion screw tube that is freely movable, and the extrusion screw tube is rotated in conjunction with the rotation of the drive shaft to rotate the extrusion screw tube around the axis. An extrusion female threaded part movable in the direction is provided in the casing, an extrusion spring is interposed between the extrusion threaded cylinder and the gripping male threaded part, and an extrusion spring is interposed between the base end of the drive shaft and the support cylinder. 1. A segment gripping device for a segment assembly apparatus, characterized in that a retracting spring is interposed in the segment holding device, and a rotary drive device capable of forward and reverse rotation is provided which is interlocked with the support tube and rotates a drive shaft.
