Title:
建造物の点検方法及び点検装置
Document Type and Number:
Japanese Patent JP6941834
Kind Code:
B2
Abstract:
To be able to move a rotorcraft while pressing a wheel against a wall surface to be inspected without requiring delicate remote control, and to ensure that location information of defect-located areas are correctly obtained even in locations that radio waves from GPS satellites have difficulty reaching.SOLUTION: A small-sized rotorcraft 51 is made to fly by remote control. A pair of wheels 131 provided rotatably around a horizontal axis on the rotorcraft 51 are pressed against a wall surface W of a building to be inspected, and the rotorcraft 51 is moved in the vertical direction as is. During that time, the rotation of the wheels 131 is detected by a rotary encoder, and the wall W is continuously struck by a striking sound diagnostic device 151 to collect the striking sound at that time. Further, the positional deviation of the rotorcraft 51 with respect to the wheels 131 is absorbed by allowing the displacement between the wheels 131 and the rotorcraft 51 to be elastically received.SELECTED DRAWING: Figure 13
