Description

X선 비파괴 검사용 필름지지장치 {FILM SUPPORT DEVICE FOR TESTING X-RAY NON-DESTRUCTIVE}Film support device for X-ray nondestructive inspection {FILM SUPPORT DEVICE FOR TESTING X-RAY NON-DESTRUCTIVE}

본 발명은 X선 비파괴 검사용 필름지지장치에 관한 것이다.The present invention relates to a film support apparatus for X-ray nondestructive inspection.

파이프와 같은 용접라인을 가지는 검사대상은 용접한 후 용접라인에 기공이나 균열과 같은 결함의 존재 유무를 확인하기 위해 비파괴 검사를 실시하며, 일반적으로 X선 검사장치가 널리 이용되고 있다.Inspection objects having a welding line such as a pipe are subjected to non-destructive inspection to confirm the presence of defects such as pores or cracks in the welding line after welding, and generally, X-ray inspection apparatuses are widely used.

X선 비파괴 검사의 경우, 검사대상 용접라인을 따라 검사대상의 일면에 감광필름을 설치하고 그 반대편에 X선을 조사하여 감광필름에 맺힌 상으로 결함의 유무를 판단한다.In the case of X-ray nondestructive inspection, a photosensitive film is installed on one surface of the inspection object along the welding line to be inspected, and X-rays are irradiated on the opposite side to determine whether there is a defect on the photosensitive film.

감광필름을 설치할 때에는, 예를 들어 파이프의 경우, 작업자가 파이프 내부로 들어가 용접라인을 따라 감광필름을 부착하여야 한다. 이때 X선 조사기는 조사의 폭이 한정되어 있으므로 통상의 경우 1회의 유효 조사 폭에 대응하는 길이의 감광필름을 매 조사 시마다 부착 및 탈착을 반복한다. 미리 한꺼번에 연속하여 감광필름을 배치할 경우 한 영역의 X선 조사 시 인접한 감광필름에 원하지 않게 노광되어 사용이 불가능하게 되어버릴 수 있기 때문이다. 그래서 인접 영역의 조사 시 영향을 받지 않도록 상호 이격 간격을 두고 감광필름을 연속적으로 배치하여 1차적으로 조사 작업을 시행한 후, 1차 감광필름을 모두 제거한 다음 1차에서 감광필름이 부착되지 않았던 이격 간격에 대해서는 2차적으로 필름을 부착하고 X선을 조사하여 작업을 마무리하기도 한다.When installing the photoresist film, for example in the case of pipes, the operator must enter the pipe and attach the photoresist along the welding line. At this time, since the radiation width of the X-ray irradiator is limited, in general, the photosensitive film having a length corresponding to one effective irradiation width is repeatedly attached and detached at every irradiation. This is because when the photosensitive film is continuously disposed at a time in advance, it may be undesirably exposed to the adjacent photosensitive film during X-ray irradiation of one region, making it impossible to use. Therefore, the photosensitive film is continuously arranged at a mutually spaced interval so as not to be affected by the irradiation of adjacent areas, and after the first irradiation work, all the first photosensitive film is removed, and then the first photosensitive film is not attached to the first step. For the gap, the film is secondarily attached and X-rays are used to finish the work.

경우에 따라서는 작업자가 파이프 내부로 들어가지 않고 감광필름이 부착된 붐대를 파이프 내부에 장입시켜 비파괴 검사가 이루어지기도 한다.In some cases, a non-destructive inspection may be performed by placing a boom with a photosensitive film inside the pipe without the worker entering the pipe.

이와 같이 종래의 X선 비파괴 검사는 감광필름의 부착과 탈착 작업이 매우 불편하고 시간이 많이 소요되는 문제점이 있다.As described above, the conventional X-ray nondestructive inspection has a problem in that the attachment and detachment of the photosensitive film is very inconvenient and time consuming.

이하, 본 발명에 따른 실시예를 도면을 참조하여 설명하기로 한다.Hereinafter, an embodiment according to the present invention will be described with reference to the drawings.

도 1에 도시된 바와 같이 X선 비파괴 검사 장치(1)는 붐대(10)와, 붐대(10)를 지지하는 지지아암(50)과, 붐대(10)를 회전시키는 회전구동부(40)로 이루어진다.As shown in FIG. 1, the X-ray nondestructive testing device 1 includes a boom 10, a support arm 50 for supporting the boom 10, and a rotation driving unit 40 for rotating the boom 10. .

붐대본체(12)는 파이프(20)의 용접라인(22)과 대응하도록 긴 막대형상을 가지며, 회전구동부(40)에 의해 붐대본체(12)는 길이방향 회전축선을 따라 회전 구동된다.The boom base body 12 has a long rod shape so as to correspond to the welding line 22 of the pipe 20, the boom base body 12 is driven to rotate along the longitudinal axis of rotation by the rotary drive unit (40).

붐대본체(12)는 사각 단면을 가지며 길이방향을 따라 긴 표면이 형성되어 있고, 각 표면에 필름지지부(14)를 존재한다. 필름지지부(14)는 붐대본체(12)의 길이방향을 따라 각 표면에 존재한다. 도 1에 도시된 경우 붐대본체(12)는 거의 정사각형의 단면을 가지며, 각 면이 필름지지부(14)가 되어 총 네 개의 필름지지부(14)가 형성된다. 경우에 따라서 붐대본체(12)는 3각 단면을 가져 총 세 개의 필름지지부(14)가 존재할 수 있으며, 또 다른 경우에는 붐대본체(12)는 비교적 얇은 판상을 가지며, 상호 대향한 두 개의 면에 필름지지부(14)가 존재할 수 있다. 이와 같이 복수의 필름지지부(14)를 가지기 때문에 붐대본체(12)를 길이방향 회전축을 따라 회전 구동을 시켜 각각의 필름지지부(14)가 용접라인(22)의 이면과 마주할 수 있도록 한다. 복수의 필름지지부(14)에는 각각의 면에 감광필름(30)을 부착한다.The main body 12 has a rectangular cross section and has a long surface along the longitudinal direction, and has a film support 14 on each surface. The film support 14 is present on each surface along the longitudinal direction of the boom base body 12. In the case shown in Figure 1 the boom base body 12 has a substantially square cross-section, each side is a film support 14, a total of four film support 14 is formed. In some cases, the boom main body 12 may have a triangular cross section, so that there may be a total of three film supporting parts 14. In another case, the boom main body 12 may have a relatively thin plate shape and may be disposed on two opposite surfaces. There may be a film support 14. Since there is a plurality of film support portion 14 as described above to drive the boom base body 12 along the longitudinal axis of rotation so that each film support portion 14 can face the back surface of the welding line (22). The photosensitive film 30 is attached to each surface of the plurality of film support parts 14.

제1실시예에 따르면 도 1에 도시된 바와 같이 감광필름(30)의 낭비를 줄이기 위해 필름지지부(14)에 감광필름(30)을 이격 배치하여 비파괴 검사를 실시할 수 있다. 감광필름(30)을 미리 한꺼번에 배치할 경우 인접영역에 X선을 조사 시 감광필름(30)이 원하지 않게 노광되는 것을 방지하기 위함이다. 즉, 일면의 필름지지부(14)에 감광필름(30)을 이격 배치시키고, 감광필름(30)이 설치되지 않은 비조사구간에 대응하도록 타면의 필름지지부(14)에 감광필름(30)을 이격 배치시킨다. 일면의 필름지지부(14)를 용접라인(22) 이면과 마주보도록 설치하여 용접라인(22)에 X선을 조사하고, X선 조사가 끝나면 붐대(10)를 회전시켜 타면의 필름지지부(14)가 용접라인(22)의 이면과 마주보게 하여 용접라인(22)에 X선을 조사하는 방법을 이용하여 감광필름(30)의 낭비를 줄이면서도 모든 용접라인(22)을 검사할 수 있다.According to the first embodiment, as shown in FIG. 1, in order to reduce waste of the photosensitive film 30, the non-destructive inspection may be performed by arranging the photosensitive film 30 spaced apart from the film support 14. This is to prevent the photosensitive film 30 from being undesirably exposed when X-rays are irradiated to adjacent areas when the photosensitive film 30 is disposed at a time. That is, the photosensitive film 30 is spaced apart from the film support 14 on one surface, and the photosensitive film 30 is spaced apart from the film support 14 on the other surface so as to correspond to the non-irradiation section where the photosensitive film 30 is not installed. Place it. One side of the film support 14 is installed so as to face the back of the welding line 22 to irradiate the X-ray to the welding line 22, and after the X-ray irradiation, the boom 10 is rotated to rotate the film support 14 of the other side All welding lines 22 can be inspected while reducing waste of the photosensitive film 30 by using a method of irradiating X-rays to the welding line 22 by facing the back of the welding line 22.

제2실시예에 따르면 파이프(20)의 일부 구간에 대해 샘플링검사를 실시할 경우 필름지지부(14)의 일부 구간에만 감광필름(30)을 지지하여 비파괴 검사를 실시할 수 있다. 제1실시예의 경우와 달리 하나의 파이프(20)의 용접라인(22)을 검사하기 위해 감광필름(30)이 이격 배치되지 않아 복수의 필름지지부(14)가 사용될 필요가 없다. 따라서 붐대(10)에 존재하는 필름지지부(14)의 수만큼 여러 개의 파이프(20)의 용접라인(22)을 검사할 수 있다.According to the second embodiment, when performing sampling inspection on a portion of the pipe 20, the non-destructive inspection may be performed by supporting the photosensitive film 30 only in a portion of the film support 14. Unlike the case of the first embodiment, the photosensitive film 30 is not spaced apart to inspect the welding line 22 of one pipe 20, so that the plurality of film supporting parts 14 need not be used. Therefore, the number of welding lines 22 of the pipes 20 can be inspected as many as the number of the film supporting parts 14 present in the boom 10.

만약 붐대본체(12)가 4개의 필름지지부(14)를 가질 경우 먼저 첫번째 파이프(20)가 비파괴 검사 장치(1) 내에 장입되어 한 면의 필름지지부(14)가 파이프(20) 용접라인(22)의 이면과 마주하게 설치한다. 그 후 필름지지부(14)와 대응하는 용접라인(22)에 X선을 조사하여 비파괴 검사를 실시한다. 검사가 완료되면 다음으로 두번째 파이프(20)를 비파괴 검사 장치(1) 내부로 장입시키고, 이때 붐대(10)를 회전시켜 타면의 필름지지부(14)가 용접라인(22)의 이면과 마주하게 설치한 후 비파괴 검사를 실시한다. 이와 같이 복수의 필름지지부(14)를 가진 붐대(10)를 회전시켜 한 번의 감광필름(30) 부착으로 복수의 파이프(20)를 검사 가능하다.If the boom main body 12 has four film supports 14, the first pipe 20 is first loaded into the non-destructive inspection device 1 so that the film support 14 on one side is welded to the pipe 20. Install facing the back side of). Thereafter, X-rays are irradiated to the welding line 22 corresponding to the film support 14 to perform a nondestructive inspection. After the inspection is completed, the second pipe 20 is charged into the non-destructive inspection device 1, and at this time, the boom 10 is rotated so that the film support 14 on the other side is installed to face the back of the welding line 22. Non-destructive testing is performed. In this way, the plurality of pipes 20 can be inspected by attaching the photosensitive film 30 by rotating the boom 10 having the plurality of film support parts 14.

붐대본체(12)의 일측 단부에는 구동회전축(16)이 형성되며, 붐대본체(12)의 타측 단부에는 자유단회전축(18)이 형성되어 있다.A driving rotary shaft 16 is formed at one end of the boom base body 12, and a free end rotation shaft 18 is formed at the other end of the boom main body 12.

구동회전축(16)와 결합된 회전구동부(40)는 회전구동모터(42)에 의해 구동되며, 구동회전축(16)을 회전시키는 역할을 한다. 구동회전축(16)이 길이방향 축선을 따라 회전 구동하게 되면 붐대(10) 또한 길이방향 축선을 따라 회전하게 되어 다면의 필름지지부(14)가 용접라인(22) 이면과 마주보게 된다. 경우에 따라서 필름지지부(14)가 두 면으로 이루어질 경우 회전구동부(40)를 조절하여 붐대본체(12)가 180o 회전하도록 하며, 필름지지부(14)가 네 면으로 이루어질 경우 회전구동부(40)를 이용하여 붐대본체(14)가 90o씩 회전하도록 조절할 수 있다.The rotary drive unit 40 coupled to the drive rotary shaft 16 is driven by the rotary drive motor 42 and serves to rotate the drive rotary shaft 16. When the driving rotary shaft 16 is driven to rotate along the longitudinal axis, the boom 10 also rotates along the longitudinal axis such that the film support 14 on the side faces the back of the welding line 22. In some cases, when the film support 14 is made of two surfaces, the boom base body 12 is rotated by 180 ° by adjusting the rotation driving part 40, and when the film support 14 is made of four surfaces, the rotation driving part 40 is formed. By using the boom base body 14 can be adjusted to rotate by 90 o .

회전구동부(40)를 이용하여 구동회전축(16)을 축방향으로 회전시키면 붐대본체(12) 및 붐대본체(12)의 타측 단부에 마련된 자유단회전축(18)도 함께 회전 구동한다. 자유단회전축(18)은 길이방향 축선을 따라 회전 가능하도록 존재하는 지지아암(50)에 의해 지지된다.When the drive rotary shaft 16 is rotated in the axial direction using the rotary drive unit 40, the boom base body 12 and the free end rotation shaft 18 provided at the other end of the boom base body 12 are also driven to rotate together. The free end rotation shaft 18 is supported by a support arm 50 which is rotatably present along the longitudinal axis.

지지아암(50)은 도 2b에 도시된 바와 같이 자유단회전축(18)을 지지하기 위한 축지지부(52)를 포함하고 있다. 회전구동부(40)에 의해 붐대(10)가 회전하게 되면 구동회전축(16)은 회전구동부(40)에 의해 회전 지지되며, 자유단회전축(18)은 축지지부(52)를 포함하는 지지아암(50)에 의해 회전 지지된다. 축지지부(52)는 상부가 개방되어 있으며 자유단회전축(18)이 외부로 이탈되는 것을 방지하기 위해 자유단회전축(18)의 하부를 거의 반원형으로 둘러싸며 지지한다.The support arm 50 includes a shaft support 52 for supporting the free end rotation shaft 18 as shown in FIG. 2B. When the boom 10 is rotated by the rotary driving unit 40, the driving rotary shaft 16 is rotated and supported by the rotary driving unit 40, and the free end rotating shaft 18 includes a support arm including the shaft supporting unit 52. Rotationally supported by 50). The shaft support portion 52 is open at an upper portion thereof and supports the lower end of the free end rotation shaft 18 in a substantially semicircular shape to prevent the free end rotation shaft 18 from being separated outward.
