INSPECTION ROBOT
Document Type and Number:
Japanese Patent JP2016043726
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an inspection robot suitable for inspection of a steel bridge.SOLUTION: An inspection robot has a main body 2 on which an inspection device 5 is loaded, a pair of front wheels 3, 3, and a pair of rear wheels 4, 4. The front wheel 3 and the rear wheel 4 have plural magnets, which are located in a circumferential direction, on outer diameter sides. The front wheel 3 and the rear wheel 4 are so located as to be overlapped with each other in a rotary shaft direction view. The front wheel 3 and the rear wheel 4 are adsorbed onto a steel component 20 of a structure and are rotationally driven, and thereby the front and real wheels are travelled along the steel component 20. When the front and rear wheels reach a predetermined inspection position, inspection of the structure is performed by the inspection device 5. The robot moves from a vertical plane 21 of the steel component 20 to a downward horizontal plane 22 without contact of the main body 2 with a corner between the vertical plane 21 and the downward horizontal plane 22. Further, when the robot moves from the vertical plane 21 of the steel component 20 to the downward horizontal plane 22, contact points C1, C2 are always formed between the steel component 20, and the front wheel 3 and the rear wheel 4.SELECTED DRAWING: Figure 4
