MEASURING INSTRUMENT OF CONDUIT LINE BEND

摘要

PURPOSE:To enable the detection of the bending state of conduit line easily by remote control by having the main body with the detector on board to output with detecting a position and/or the variation in the position and the supporting body for keeping this main body on the axial line position of the conduit line. CONSTITUTION:The measuring instrument of the bend of conduit line has a rolling angle detector 15 and the upper and lower and right and left directions detectors 16, 17. And these detectors incorporate the sensor to output electrical signal by detecting respectively the angle and the output signal is fed to a display recorder 19 by a cable 18 and recorded. Four pieces of legs 7 for keeping the tip part of the rear part of the tail part 6 of the main body on the center line B are provided thereon. Now when a bend is found on the center line of the conduit line an output appears on either or both of the direction detectors 16, 17. On the other hand the position of the measuring instrument C at each time is detected by the output of a rolling angle detector 15. The state of the bend of the conduit line can be thus detected easily by remote control.
