On the other hand, the "boiler tube inspection device" is a device that can be used only on a tube that can be inserted into a tube from the outside. In this case, it is impossible to insert a probe for each tube, and since both hands are not free on the workbench, it is difficult to work safely and there is a high risk of safety accidents, and there is a problem that cannot be applied to large boiler facilities.

In addition, the "injection device and leak detection module" is inaccurate as it relates to the user's perception, there is a risk that the orifice of the spray gun is clogged, trace gas is emitted around the test target, and measurement errors may occur, and the amount of gas This can be increased by background noise, and we propose an injection device and an injection module that detect a leak that can solve these drawbacks, but the injection device, the leak detector, and the tracer gas cartridge are flexible lines except for the leak detector. Because they are connected, both hands are not free when measuring an object, so there is a problem in that work efficiency is lowered.

In addition, as the operator has to measure with a probe for thickness measurement in one hand and a thickness gauge and probe liquid in the other hand, both hands are not free and the tube thickness measurement device may fall. As it takes a long time for the measurement work, the fatigue of the operator is increased, and there is a problem that there is a high risk of a safety accident when the measurement work is performed at a high place.

In addition, the nozzle combined measuring unit 40 is connected to each of the automatic ejectors 10 and the ultrasonic thickness gauge 30 to interlock when they are operated, so that the ejection nozzle 16 and the probe 34 are integrated into one single unit. It is formed of a nozzle and a measuring body 42 .

In addition, the nozzle combined measuring unit 40 is formed so that the tip of the discharge nozzle 16 does not exceed the tip of the probe 34 .

Hereinafter, examples of use of the present invention made as described above will be described in detail with reference to the drawings.

First, by positioning the thickness measurement of the tube 32 of the boiler, the probe liquid to be applied on the surface of the tube 32 during the measurement operation is sufficiently filled in the probe liquid tank 12 of the automatic ejector 10, and the probe liquid 12 is automatically discharged. The module 14 is sealed with a plug 14a provided in the module 14 .

Next, the surface of the tube 32 of the boiler is cleaned so that the probe liquid can be applied to the surface of the tube 32 of the boiler that is the tube 32 of the boiler to be measured. As described above, when the cleaning of the tube 32 for the boiler is finished, the automatic ejector 10 is hung on the X-band of the operator so as not to always hold the automatic ejector 10 using the hook 20 provided in the automatic ejector 10 .

Accordingly, the operator can freely use one hand at a high position, as well as holding the ultrasonic thickness gauge 30 in one hand and the nozzle and measuring body 42 in the other hand to facilitate the tube 32 thickness measurement operation. Through this, the operator can measure the thickness of the tube 32 while ensuring safety at the high position.

As described above, when the work preparation for the tube thickness gauge (2) of the boiler is completed, the power switch (14b) of the automatic discharge module (14) provided on the probe liquid tank (12) of the automatic discharger (10) is operated and operate the automatic ejector (10). When the automatic ejector 10 is in an operating state, the probe liquid ejection button 14c is pressed. Accordingly, the probe liquid of the probe liquid barrel 12 is discharged from the discharge nozzle 16 of the nozzle and measuring body 42 through the probe liquid outlet 14d and the supply hose 16a of the automatic discharge module 14. The probe liquid discharged through the discharge nozzle 16 is discharged to the tip of the probe 34 connected to the portable ultrasonic thickness gauge 30 by an electrical line 34a.

At this time, when the probe liquid starts to be discharged to the tip of the probe 34, the operator puts the probe 34 of the measuring body 42 for both nozzles in contact with the tube 32 surface close to the surface of the tube 32 to measure the thickness. Apply to the surface. That is, whenever the probe liquid is discharged from the discharge nozzle 16 for a certain period of time, the probe liquid is applied to the surfaces of the tubes 32 to be thickness measured using the flop 34 .

In addition, after applying the probe to the surface of the tube 32, the power switch operation is provided in the nozzle and measuring body 42 connected to the ultrasonic thickness gauge 30 in the standby state through the electrical line 34a. The thickness of the tube 32 is measured by manipulating the probe 34 to adhere to the surfaces of the tubes 32 to which the probe liquid is applied. The measured value for the thickness of the tube 32 is directly displayed on the display window 32a of the ultrasonic thickness gauge 30 . Accordingly, if the operator confirms the measured value displayed on the display window 32 and writes it on the chart or inputs it into a prepared mobile measurement management device, it may be utilized during maintenance and inspection of the boiler tube in the future. In addition, whenever the tube thickness measurement operation of the boiler is completed, the operation can be repeated after moving to the next measurement position. That is, it is possible to continuously supply the probe 34 to the probe 34 of the nozzle and measuring body 42 using the automatic ejector 10, so that the tube 32 thickness measurement operation can be performed quickly.

In addition, the operation of measuring the thickness of the tubes 32 provided in the large boiler in the power plant makes it possible to easily measure the thickness of the tube without inserting the probe 34 into the tube 32 . In addition, even when tube thickness measurement is performed at a high position on the scaffold, if the tube thickness gauge 2 is used, the operator's hands are free, so the workability of measuring the thickness of the tube 32 is good, and safety can be secured to some extent at a high position. It has the advantage of improving the stability and also improving the measurement work efficiency because it can work quickly.

The embodiments of the tube thickness gauge of the boiler of the present invention described above are merely exemplary, and those of ordinary skill in the art to which the present invention pertains can make various modifications and equivalent other embodiments therefrom. You will know well. Therefore, it will be well understood that the present invention is not limited to the form mentioned in the above detailed description. Therefore, the true technical protection scope of the present invention should be determined by the technical spirit of the appended claims. Moreover, it is to be understood that the present invention covers all modifications, equivalents and substitutions falling within the spirit and scope of the invention as defined by the appended claims.
