Here, the object to be inspected is an industrial equipment to be inspected, which includes a large steel and a non-steel container containing industrial piping or various raw materials and gas.

For reference, an X-ray is an electromagnetic wave having a short wavelength generated when a high-speed electron flow is collided with a material. The X-ray is small in atom size and forms a diffraction pattern unique to each crystal. The transmittance varies depending on the density and the atom. The x-ray tube 200 is used in the non-destructive testing equipment of the general industry using this principle.

Due to the nature of non-destructive testing of industrial equipment, industrial equipment, which is the object of inspection, is of high weight and very large in volume, so it is inevitable to operate the X-ray tube instead of moving the object to be inspected.

First, the mobile carrier 100 moves the X-ray tube 200 to a position where the object to be inspected is located and lifts it up and down.

The lift process of the mobile carrier 100 will be described below.

Since the first drive motor M1 rotates the first pinion gear 150 and the first pinion gear 150 is engaged with the first rack 140, the ascending / descending block 130 is lifted upward.

The second driving motor M2 rotates the second pinion gear 180 and the second pinion gear 180 is engaged with the second rack 170 so that the mounting bracket 160 is lifted upwards The height of the x-ray tube 200 can be adjusted.

After the height of the X-ray tube 200 is adjusted, the worm gear 431 connected to the gear box 432 is rotated by driving the servo motor 433. At this time, the servo motor 433 can be controlled from a remote place by using the wireless communication unit 434. [

By the rotation of the worm gear 431, a rotational force is transmitted to the ring gear 440 so that the x-ray tube 200 rotates at a predetermined angle.

At this time, the ring-shaped holder bracket 420 is installed so as to roll with the X-ray tube retaining ring 410. The X-ray tube retaining ring 410 and the ring-shaped holder bracket 420 are rotatably supported by the first bearing B1 and the second bearing B2. The rolling motion of the roller 420 is smoothly performed.

As described above, the nondestructive inspection for inspecting industrial equipments is inevitably required to operate the X-ray tube instead of moving the object to be inspected due to the characteristics of heavy and bulky industrial equipments. The worm gear and the ring gear are configured to adjust the angle of the X-ray tube and the electromotive driving method of the servo motor is adopted. By adopting the measurement environment of the high-weight 450 kV class X-ray tube mounted on the mobile carrier, Control and precision non-destructive inspection are possible, and the quality of nondestructive inspection can be improved by improving the x-ray imaging environment of nondestructive inspection.
