  • Patent number: 9145791
    Abstract: The present disclosure relates to an automatic inspection apparatus for generator turbines and a system using the same. The automatic inspection apparatus adjusts the height of an arm via a lifter, adjusts a rotating angle relative to an inspection object via a rotator, and adjusts forward or backward movement of a probe relative to the inspection object via an expansion/contraction unit while moving the arm having the probe on a rail in accordance with positions of a turbine to be inspected. Furthermore, a compression unit may be used to control contact pressure of the probe to the inspection object at a desired level to allow the probe to closely contact the inspection object, thereby preventing disturbance due to vibration of the probe. In addition, the automatic inspection apparatus has a simple and lightweight configuration so as to be easily installed or removed in a work site.
