The present invention relates to a radiation source device, and more particularly, to construct a contact sensor on a support plate to check whether the object is stably seated on the radiation source device, and to shield the scattering line generated during the non-destructive test to provide safety. The present invention relates to a radiation source device that enhances the product competitiveness by constructing a height measuring sensor in a lifting unit so that the same height is always maintained when the radiation source device is moved to the inspection position of an object, thereby obtaining an optimum sensitivity. .

In general, a nondestructive test (NDT) is a type of product or structure, and the presence or absence of internal defects on the surface of the test object and the condition and the object of the test object are kept intact without damaging, separating or destroying the test object. After examining the internal structure, etc., it is a test method to make a judgment on the availability of the test object based on a certain criterion.

The non-destructive inspection is used to determine the surface defects of large parts such as the main shaft of the wind turbine or to inspect the defects such as pores or cracks in welding lines such as pipes, and the like, ultrasonic inspection, radiographic inspection, magnetic particle inspection. There are various types of examinations, such as liquid penetrant examination, and the most widely used is gamma ray non-destructive examination.

The gamma ray non-destructive inspection is a method of determining the presence of defects by installing a photosensitive film on the surface of the inspection line, for example, the surface of a large part or a welding line, and then transmitting the image to the photosensitive film through the gamma ray.

At this time, the gamma ray, that is, radiation has a property of going straight, because the leakage of radiation to the opposite part of the inspection line can be covered by the operator, in order to prevent this, shielding function of the radiation in the opposite position of the inspection line The eggplant puts the lead plate.

That is, the radiation source device 100 is configured at the lower end of the pipe, and the image plate 300 is configured in a direction opposite to the radiation source device 100.

In addition, the radiation source device 100 is composed of a radiation source 110 for irradiating radiation, and a collimator (130) formed to adjust the irradiation angle of the radiation irradiated from the radiation source 110 constant.

The collimator 130 has a cylindrical shape having a length longer than approximately a diameter, and a portion of the collimator 130 is formed in a concave groove shape to adjust the irradiation angle in the longitudinal direction of the cylinder. That is, the concave portion of the collimator 130 is formed to be wider in the outward direction at the portion where the radiation source 110 is located to adjust the angle of radiation irradiated from the radiation source 110.

In addition, the radiation source 110 is a radiation source comprising a capsule 112 having a radioisotope embedded therein, a cable 114 connected to the capsule 112, and a remote control device connection portion at an end thereof. Since the radiation source 110 is a general technical idea, a detailed description thereof will be omitted.

Accordingly, the radiation emitted from the capsule 112 is irradiated in a rectangular shape to match the shape of the image plate 300 as a whole by the collimator 130, thereby obtaining a test image.

However, in the conventional radiation source device, when the measurement distance with the first object is fixed, the measurement distance is fixed until the measurement on the object is completed, so that the curvature of the object does not correspond and the measurement is not made to obtain a clear measurement sensitivity. There is a problem.

In addition, the conventional radiation source device has a problem that the general purpose for the use of the radiation source device is inferior because the dedicated radiation source device must be separately configured and measured according to the state of the object, for example, the horizontal state or the vertical state.

Looking at the control method for the radiation source device configured as described above with reference to FIG.

First, after mounting the radiation source device on the object (ON), the power is turned on (ON), it is a step (S1) to check whether the contact sensing signal is confirmed by the contact sensor 140 of the support means (10).

If the touch sensing signal is not transmitted from the touch sensor 140 to the control unit 40, it is determined that the radiation source device 1 is not stably seated on an object or is not a position for performing a non-destructive test. Do not perform nondestructive testing.

If the contact sensor signal is confirmed (S1), it is selected whether to use the electromagnet fixing unit (140) (S2).

Accordingly, the driving unit 210 is driven by the control of the controller 40 according to the height value measured by the height measuring sensor 238, thereby automatically adjusting the height of the object and the radiation means 30.

When the radiation means is automatically adjusted to the set height (S5), through the collimator 320 configured in the radiation means 30 starts the inspection of the inspection position of the object and completes the inspection over a certain time (S6).

When the inspection starts and is completed (S6), it is determined whether the radiation source device is moved to the next inspection position (S7).

If the inspection of the object is completed through the radiation source device (1), the control method is terminated.

Or, if you want to move to the next inspection position with respect to the target object through the radiation source device (1) by moving to the step (S4) to move to the above-described radiation source device inspection position, it performs a non-destructive inspection of the object.

The shielding plate 150 is formed at a predetermined length at a lower end of the first shielding member 150a and the lifting plate 232 of the elevating unit 230, one end of which is fixed to the support plate 110 and formed at a predetermined length. And a second shielding member 150b, while maintaining the neighboring surfaces of the first shielding member 150a and the second shielding member 150b in close contact with each other, according to the lifting height of the lifting unit 230. The radiation source device, characterized in that the closed state is maintained by close contact with the first shielding member (150a) even if the second shielding member (150b) is elevated to maintain the shielding function. delete The method according to claim 1,
It is provided at the bottom of the support plate 110 of the support means 10, and maintains a fixed state when the object is made vertically so that the power can be used universally even when the object is horizontal or vertical (ON) / off (ON) Radiation source device further comprises; electromagnetism unit 160 for generating a magnetic force according to (OFF). The method according to claim 1,
The elevating guide means 20 has a horizontal holding unit 240 to support the elevating plate 232 to be elevated in place of the support 220, the stable;
The horizontal holding part 240 is installed so as to pass through each of the four corners of the elevating plate 232, the guide shaft is provided on each of the two sides of the rack gear 242 made of a plurality of gear teeth formed along the longitudinal direction orthogonal 241, a plurality of pinion gears 244 meshed with the rack gears 242, and a connecting shaft 246 connecting the two pinion gears 244 meshed with the rack gears in the same direction, respectively; And a gear housing 248 provided on the elevating plate 232 to rotatably support the pinion gear 244.
When the elevating unit 230 is elevated by the driving force of the driving unit 210, the pinion gears 244 are interlocked with each other to move up and down along the longitudinal direction of the rack gear 242 so that the elevating unit 230 is in a horizontal state. Radiation source device, characterized in that to be maintained. delete
