[0001] The present invention relates to an ultrasonic inspection apparatus provided with an extended variable type biaxial rail, and more particularly, to an ultrasonic inspection apparatus provided with an extended variable type biaxial rail, The present invention relates to an ultrasonic inspection apparatus having an extended variable-type two-axis rail capable of adjusting a length of a rail.

In general, a conventional ultrasonic inspection apparatus for inspecting welding defects of a hull is equipped with an ultrasonic probe on a base which is made to be able to travel by a motor drive, and a probe is brought into close contact with the surface of the object to be inspected during traveling, Thereby inspecting defects.

The ultrasonic inspection is a non-destructive inspection method for analyzing the position and size of defects by analyzing the energy amount and the processing time of the ultrasonic waves reflected from the defects existing inside by transmitting the ultrasonic waves to the inspection object. The amount of energy of the ultrasonic waves reflected from the discontinuities existing in the lower surface and the time of the ultrasonic waves are analyzed to accurately determine the position and size of the discontinuity.

Such ultrasonic inspection is most widely used in conjunction with radiographic inspection in order to identify the discontinuity in the interior of the object. However, it can be easily inspected even if the thickness of the object is thick, This is an excellent advantage.

In addition, the ultrasonic inspection used in the industrial field is not only for inspection of laminations, cracks and inclusions contained in the discontinuities of the base material but also for inspection of pores, cracks, inclusions and fatigue cracks And is used for detection. It can be used not only for steel but also for bridges made of non-steel materials, steel structures, shipbuilding, pressure vessels, general machinery parts and so on.

Therefore, even if the shaft p rotates eccentrically or tilts in the longitudinal direction, the state in which the roll 170 is in close contact with the axis p can be maintained by the compression spring 150 Therefore, the contact portion 113 of the ultrasonic probe 110 can prevent the occurrence of uneven wear, so that the contact state can be maintained without being always spaced apart from the axis p, so that accurate pulse data can be obtained .
