ものである。 In this way, the pantograph part 8 is connected to the inner tube 7 and the outer tube 6.
When the outer tube 6 is fixed and the inner tube 7 is moved to the left as indicated by the arrow in FIG. 1, the pantograph section 8 becomes higher. A spring shown as 10 in the figure is provided between the inner tube 7 and the outer tube 6, and the spring 10 is provided to the inner tube 7 via a stopper 11.
A spring 10 is similarly provided on the outer tube 6 via a stopper 11. Further, twelve position sensors are provided in the figure, and a push rod 13 is provided between the position sensors 12 and the stopper 11 of the inner tube 7. It is therefore possible to measure the distance over which the spring 10 expands using the push rod 13. The distance of this push rod 13 is measured by the position sensor 12, and the degree of expansion of the pantograph section 8 can be measured.

る。 First, the outer tube 6 is fixed, the inner tube 7 is moved to the left, and the pantograph section 8 is inserted into the tap port of the converter with the height lowered. When the force that was moving the inner tube 7 to the left is released, the inner tube 7 moves to the right in the figure due to the repulsive force of the spring 10. Then, the height of the pantograph section 8 becomes higher, and the pantograph section 8 comes into contact with the tap hole 4 at a height equivalent to the diameter of the tap hole 4, and the pantograph section 8 stops. Then, the user slowly pulls the outer tube 6 while supporting only the outer tube 6 to the desired position, and uses the position sensor 12 to measure the length of the push rod 13 with the pantograph section 8 stopped. The output from the position sensor 12 is connected to the dynamic strain meter 14, and further,
It is connected to the recorder 15 so that the chart can be recorded.
