PURPOSE:To detect the shape of the surface of a body, which is located in an environment where a man cannot approach and faces a narrow gap, safely and readily, by running a self-propelled truck in the gap having a part to be measured. CONSTITUTION:A shape detecting mechanism 1, an angle detecting mechanism 2, and a moving-amount detecting mechanism 3 are connected to an operation circuit 4. To the operation circuit 4, the following devices are connected: an inspection amount display 5, which performs the display corresponding to the signal from the shape detecting mechanism 1; a slant angle display 6, which performs the display corresponding to the signal from the angle detecting mechanism 2; a moving-amount display 7, which performs the display corresponding to the signal from the moving-amount detecting mechanism 3; and an X-Y plotter 8, which displays the shape of the surface to be inspected. The shape detecting mechanism 2 is attached to the lower surface of the central part of the self-propelled truck 20. The self-propelled truck 20 is provided with a pair of protruding mechanisms 22 at the right and left parts. The protruding mechanisms 22 rotate a pair of rotary arms 24 and 24 having guide rollers 23 outward against springs 25. Thus, the self-propelled truck 20 is stabilized and held in the gap to be measured. |
