PROBLEM TO BE SOLVED: To provide a structure inspection robot capable of running at a location where a projected member of a structure is provided, reducing an inaccessible area in the structure than ever before, and inspecting wider area than ever before.SOLUTION: A structure inspection robot 1 comprises: a main body 2 mounted with inspection devices 5; a pair of fron wheels 3, 3; and a pair of rear wheels 4, 4. The front wheel 3 and the rear wheel 4 have: multiple magnets disposed on an outer diameter side in a circumferential direction; and a shielding part that covers a side part and a bottom part of the magnet. The front wheel 3 and the rear wheel 4 have conical-shaped contact parts 32, 42 provided on both sides in a width direction. The structure inspection robot 1 runs along a steel member by the front wheel 3 and the rear wheel 4 being rotated and driven while magnetically adsorbing to the steel member of a bridge. As the contact parts 32, 42 contact a bolt and nut and receive reaction force, which changes a travelling direction of the wheels 3, 4 to a direction avoiding the bolt and nut, when the structure inspection robot 1 runs on a splice part, the wheels 3, 4 can avoid a trouble, such as engaging to or running on the bolt nut.SELECTED DRAWING: Figure 1 |
