Abstract
PURPOSE: To secure an accurate measurement for the track alignment in terms of the unevenness, the passing error and others by detecting the displacement of the front and rear wheels and then correcting the detection value of the relative displacement to the frame of the intermediate wheel.
CONSTITUTION: When the device passes through on the projection of track surface 1, detector 11a and 11b such as the acceleration sensor or the like detect the displacement of support wheel 3a and 3b caused according to the uneveness of the track surface in the form of the electric quantity. At the same time, detector 10 detects the relative displacement between frame 2 and measuring wheel 4 directly in the form of the electric quantity. Here, the detection is given to the electric quantity detected through detector 11a and 11b with 1/2 sensitivity and as shown by dot line 13a and 13b. In this case, the electric quantity shown by dit line 12a and 12b which detected directly the relative displacement between wheel 4 and frame 2 is added with the electric quantity of 1/2 displacement of wheel 3a and 3b detected through detector 11a and 11b. And finally a displacement is given to frame 2 through the fact that wheel 3a and 3b pass through on the track unevenness as shown by solid line 14, and thus a perfect correction is given to the error of the measurement result detected through detector 10. As a result, the measurement corresponding exactly to the form of the actual track.
