  • Patent number: 11725922
    Abstract: A length measuring jig measures the length of a tubular stud bolt with a central hole defined axially therethrough while the tubular stud bolt remains mounted on a target product such as a steam turbine casing. The length measuring jig includes a rod to be inserted into the central hole in the stud bolt, a first jaw provided on a tip end of the rod for abutting against an end face of the one side in longitudinal direction of the stud bolt, a slider on which the rod is slidably supported, a second jaw provided on the slider for abutting against an end face of the other side in longitudinal direction of the stud bolt, and a cap to be fitted in the central hole in the stud bolt and having a slit defined therein for allowing the rod to extend therethrough. The first jaw has an overall length smaller than a diameter of a minimum-diameter portion of the central hole in the stud bolt.

  • Patent number: 11668208
    Abstract: A positioning method of an arc-like member according to at least one embodiment of the present invention includes a step of moving a protruding part disposed at a circumferential end of the arc-like member in a radial direction with respect to a reference member positioned on a radially outer side as viewed from the circumferential end of the arc-like member. In the step of moving the protruding part, a wall portion is arranged on a radially outer side or a radially inner side with respect to the reference member, a jack is arranged between the wall portion and the reference member, and the jack is operated to move the protruding part with respect to the reference member by the pressing piece mounted on the wall portion via a rod.
