Title:
PIPE LINE MEASURING APPARATUS
Document Type and Number:
Japanese Patent JP2017227522
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a pipe line measuring apparatus capable of re-measuring a route in a short time, even when the route of a pipe line is changed.SOLUTION: Inertia measuring means 4 includes a first inertia measuring means 41 provided in a first pipe body 31, a second inertia measuring means 42 provided in a second pipe body 32, and a third inertia measuring means 43 provided in a third pipe body 33. The first to third inertia measuring means 41 to 43 measure the inertias of the respective first to third pipe bodies 31 to 33. Encoders 5 include a first encoder 51 provided in a first connection part 21 and a second encoder 52 provided in a second connection part 22. In the first encoder 51, the rotation angle of the second pipe body based on the first pipe body 31 is measured. In the second encoder 52, the rotation angle of the third pipe body 33 based on the second pipe body 32 is measured. In an arithmetic means 6, the route of the pipe line comprising the pipe body 3 is calculated on the basis of the output of the measurement results of the respective inertia measuring means 4 and the respective encoders 5.SELECTED DRAWING: Figure 1
