Abstract

PURPOSE: To realize an automatic and high-precision measurement for the measurements of the monorail track digit and others by detecting the space displacement between the measurement frame and the shift frame plus the shift amount of the shift frame.
CONSTITUTION: Shift frame 5 is shifted via driving unit 21 and along reference rail 2, and this shift distance is detected by position detector 22. At the same time, the displacement is detected by displacement detectors 15W18 for the distance between the specified measurement parts on the right upper side and upper surfaces of track digit 1c for the monorail and the like and each measurement part on the upper and both side surfaces of measurement frame 8 and digit 1c kept at a fixed distance via stators 13 and 14. Then the displacement is detected by displacement detectors 19 and 20 for the distance between frame 5 and the specified measurement part of digit 1c kept at a fixed distance to frame 8. After this, the detection results are added between detectors 15W18 and detectors 19 and 20 to ensure an automatic and high-precision measurement for the displacement of each part in the longer direction and at each cross section of digit 1c.
