ABSTRACT:
The invention is objected to enable the provision of an vessel steel plate measuring device capable of measuring the thickness of vessel steel plate, even in the case of a vessel having a vessel mirror part formed by a spherical or conical curved surface such as a reactor (reaction vessel) and various kinds of obstructions at a vessel barrel. The structure of the device is characterized in that a supporting point member20is detachably provided from a supporting point set at the central axis of the vessel mirror part1aof a reactor1, and a traveling carrier6traveling on a steel plate of the vessel mirror part1aand having plural ultrasonic probes7mounted thereon is connected to one end of a turning radius regulating member19rotatively provided around the supporting point member20.
