(Conventional technology) Installed with pipes conventionally used in plants or heating furnaces, etc.
If it is not possible to remove the tube from the site, the outside diameter of the tube is measured manually on site using a caliper or other measuring device for determining the outside diameter of the tube in order to determine the degree of deterioration or g quality of the tube. However, when a large number of pipes to be measured are installed vertically, it is necessary to erect scaffolding before measuring the pipe outer diameter, and the man-hours required to assemble the scaffolding can greatly exceed the man-hours required to measure the pipe outer diameter. many. In addition, in vertical heating furnaces, etc., the inside of the furnace is narrow, so it may be difficult to construct scaffolding, and even if scaffolding can be constructed, the inside of the heating furnace is a poor environment in terms of labor safety and health due to floating soot, etc. In many cases, this caused trouble in measuring the outside diameter of the pipe.

(Problems to be Solved by the Invention) As mentioned above, even under such conditions, it is possible to measure the outer diameter of the pipe without constructing a scaffold from the viewpoint of economy and labor saving, and from the viewpoint of safety and health. It is desired that the outside diameter of the tube be easily measured using an automatic system without the need for a measuring person to enter the furnace and directly measure the outside diameter of the tube.

FIG. 3 is a diagram showing the configuration of one measurement structure used for carrying out the end-of-life test. In FIG. 3, the composite annular body 21 of the present invention is 211
! ] was used in which a reference annular body was sandwiched between centering annular bodies. This ensures accurate centering during measurements. As a moving device for moving the composite annular body 21 up and down, a part of the "automatic pipe cleaning device" described in Japanese Utility Model Application Publication No. 60-91289 was modified and used. The reason for using this "automatic pipe cleaning device" is that this device moves up and down by remote control, and at the same time uses a rotating brush to clean the pipe under test.
This is because the pipe 4 to be measured can be automatically cleaned and the pipe 4 to be measured after being cleaned can be immediately measured.

Although the structure of the measurement unit used in this example is shown in FIGS. 4 and 5, the present invention is not limited to the structure shown in FIGS. 4 and 5. In FIG. 4, when the solenoid 12 of the measuring unit is energized, the measuring contactor 3 is brought into pressure contact with the outer circumferential wall of the pipe 4 to be measured by the spring 14, so that it protrudes from the inner diameter position of the reference annular body. In this state, the output electrical signal of the differential transformer 15 changes, and the eccentric position of the measuring contactor 3 is output as an electrical signal to the computer 18 via the built-in transducer. That is, when the measurement contactor 3 is in a fixed position away from the pipe 4 to be measured (Fig. 5), for example on the inner diameter of the reference annular body 1, the output of the transducer to the computer is zero. If the zero point adjustment screw 16 is adjusted, the measurement contactor 3 will be in pressure contact with the outer wall of the tube when measuring the outer diameter of the tube, and the output of the transducer (during the measurement in Fig. 4) will be equal to the reference annular inner diameter and the measured object. This is the distance from the outer peripheral wall of the pipe. Therefore, if each interval is measured by two opposing measuring units, the outer diameter of the pipe to be measured will be the difference between the reference annular inner diameter and the sum of the respective intervals measured by the opposing measuring units. By installing a plurality of sets facing each other, the outer diameter of the pipe to be measured can be measured simultaneously from different angles. This measurement allows the outer diameter and roundness or distortion of the pipe to be measured to be measured simultaneously.

After completing the measurement at an arbitrary position on the pipe 4 to be measured, if the power supply to the measurement unit 2 is stopped, the state shown in FIG. 5 will be achieved. That is, the solenoid 12 overcomes the elastic force of the spring 14 and moves the tip of the measuring contactor 3 away from the outer peripheral wall of the pipe to be measured 4 to the reference annular inner diameter position via the solenoid link mechanism. At that time, the interval display by the electrical signal from the transducer becomes zero.

(Effects of the Invention) By repeating the above measurements, it has become possible to measure the outer diameter of the pipe to be measured by remote control in a short time and in a labor-saving manner, without the need for the measurer to manually measure it directly. There is no need to set up scaffolding for measurements, and there is great economic significance as a large number of measurements can be carried out in a short time and with little labor. Furthermore, the attached computer calculates the pipe outer diameter and transfers the pipe at the same time. It is also possible to record the moving distance of the 11J device and also record and display the relationship between the measurement position of the tube and the value of the tube outer diameter.
