DEVICE FOR INSPECTING HIGH PLACE NARROW PART

摘要

PROBLEM TO BE SOLVED: To provide a device for inspecting a high place narrow part capable of putting an electromagnet back to an original position and lowering a high place extension member to a lower level even when a power supply of a servomotor that is means for projecting the electromagnet projected from the high place extension member is lost.

SOLUTION: A gear device 24 projects an electromagnet 22 provided in the vicinity of an upper end of a high place extension member 20 on a structure side of a high place narrow part by rotation force of a servomotor 23 to make the electromagnet 22 contact with a structure 29. The electromagnet 22 is energized to fix the high place extension member 20 to the structure of the high place narrow part. When a power supply of the servomotor 23 for the electromagnet 22 is lost, a first wire 25 unlocks a gear of the gear device 24 mechanically. Thereafter, a second wire 26 puts the electromagnet 22 projected on the structure 29 side of the high place narrow part back to an original position on the high place extension member 20. Then, the high place extension member 20 is lowered to a lower level.
