Description

기계용접장비 정렬용 대형배관의 동심도 정렬지그{Concentricity alignment jig of large pipe for centering machine welding equipment}Concentricity alignment jig of large pipe for centering machine welding equipment}

본 발명은 대형배관의 동심도 측정으로 기계용접장비를 정렬하는 지그에 관한 것으로서, 더욱 상세하게는 대형배관의 기계용접장비 가이드 트랙을 따라 이동하는 지그 베이스와 다이얼게이지를 구비하는 링크부로 이루어지는 간단한 구성으로 대형배관과 기계용접장비 가이드 트랙의 정렬작업을 정밀하고 신속하게 할 수 있도록 하는 기계용접장비 정렬용 대형배관의 동심도 정렬지그에 관한 것이다.The present invention relates to a jig for aligning machine welding equipment by measuring concentricity of a large pipe, and more particularly, to a simple configuration including a jig base and a dial gauge moving along a guide track of a machine welding device of a large pipe. It relates to a concentric alignment jig of a large pipe for aligning the mechanical welding equipment, which enables precise and rapid alignment of the large pipe and the machine welding equipment guide track.

일반적으로 발전소 1차측 발전설비의 보수/교체 작업시 적용 가능한 용접방법으로는 수동 아크(SMAW)용접 방법과 수동 티그(GTAW)용접 방법이 있으나, 원자력 발전소의 특성상 용접속도보다는 고품질의 용접부가 중요시되고 있기 때문에 아크(SMAW) 용접 방법보다는 티그(GTAW) 용접 방법이 주로 사용된다.Generally, the welding method applicable to the repair / replacement of the primary power generation facilities of the power plant includes the manual arc welding method and the manual TIG welding method. However, due to the characteristics of the nuclear power plant, high quality welding parts are more important than welding speed. As a result, the GTAW welding method is mainly used rather than the SMAW welding method.

이와 같은 수동 티그용접 방법은 고품질의 용접부를 획득할 수 있으나, 용접속도는 타 용접방법에 비해 상대적으로 느리기 때문에 용접속도가 획기적으로 개선된 기계용접용 티그용접 방법이 최근에 적용되고 있는 실정이다.The manual TIG welding method can obtain a high quality welded part, but the welding speed is relatively slow compared to other welding methods, and thus the welding welding TIG welding method has been improved.

즉, 기계용접용 티그용접 방법은 높은 용접속도 및 고품질의 용접부를 획득할 수 있는 장점이 있으나, 용접작업을 위해서 무거운 용접장비 및 가이드 트랙을 피용접물에 설치하고 정렬하는데 많은 시간이 소요되어 설치시간이 길어질수록 현장 작업자의 방사선 쪼임량도 상당이 증가하게 되는 문제점이 있었다.In other words, the TIG welding method for mechanical welding has the advantage of obtaining a high welding speed and high quality welds, but it takes a lot of time to install and align heavy welding equipment and guide tracks on the welded object for welding work. As the length became longer, there was a problem that the radiation dose of the field worker was also increased.

또한 기계용접용 티그용접 방법에 있어서는 기계용접장비의 경로를 제공하는 가이드 트랙이 잘못 설치된 경우, 용접부위의 용접 품질이 떨어지는 결과가 발생하여 보수용접을 수행하는 경우가 종종 발생하게 되는 문제점도 있었다.In addition, in the TG welding method for the mechanical welding, when the guide track providing the path of the mechanical welding equipment is incorrectly installed, the welding quality of the welding part may be degraded, and thus, the repair welding is often performed.

그에 따라 종래에는 기계용접장비 가이드 트랙의 정렬 작업을 위해 마그네틱 베이스, 다이얼 게이지, 버니어 켈리퍼스 등의 계측기를 사용하여 대형배관의 동심도와 기계용접장비 가이드 트랙의 동심도를 개별적으로 측정하여 기계용접장비 가이드 트랙을 정렬하고 있었으나 배관이 대형이기 때문에 대형배관의 곡면에서 정확하고 신속한 기계용접장비 가이드 트랙의 동심도 정렬이 곤란하다고 하는 문제점이 있었다.Therefore, in order to align the machine welding equipment guide track, the machine welding equipment guide is measured by measuring the concentricity of the large pipe and the concentricity of the machine welding equipment guide track separately using a measuring instrument such as a magnetic base, a dial gauge, and a vernier caliper. Although the tracks were aligned, there was a problem that it was difficult to align the concentricity of the guide tracks accurately and quickly on the curved surface of the large pipe because the pipe was large.

본 발명은 상기한 실정을 감안하여 종래 대형배관의 기계용접장비 가이드 트랙의 정렬작업시에 야기되는 여러 가지 결점 및 문제점 들을 해결하고자 발명한 것으로서, 그 목적은 대형배관의 기계용접장비 가이드 트랙을 따라 이동하는 지그 베이스와 다이얼게이지를 구비하는 링크부로 이루어지는 간단한 구성으로 기계용접장비 가이드 트랙의 정렬 작업을 정밀하고 신속하게 하여 작업 단축에 따른 작업자의 방사선 쪼임량을 최소화할 수 있는 기계용접장비 정렬용 대형배관의 동심도 정렬지그를 제공함에 있다.The present invention has been made in view of the above circumstances to solve various defects and problems caused by the alignment of the conventional mechanical welding equipment guide tracks of large pipes, the purpose of which is along the mechanical welding equipment guide tracks of large pipes A large configuration for aligning machine welding equipment that can minimize the amount of radiation of the operator due to the shortening of work by precisely and quickly aligning the guide track of the machine welding equipment with a simple configuration consisting of a link part having a moving jig base and a dial gauge. The concentricity of the pipes is to provide the alignment jig.

본 발명의 다른 목적은 대형배관의 기계용접장비 가이드 트랙의 정렬 정확도가 1/100mm 정도로 높은 정밀한 정렬로 용접의 품질을 높여 신뢰도를 향상시킬 수 있는 기계용접장비 정렬용 대형배관의 동심도 정렬지그를 제공하는 데 있다.It is another object of the present invention to provide a concentricity alignment jig of a large pipe for mechanical welding equipment alignment that can improve the reliability by improving the quality of welding by precise alignment of the mechanical welding equipment guide track of the large pipe as high as 1 / 100mm. There is.

본 발명 기계용접장비 정렬용 대형배관의 동심도 정렬지그로 대형배관의 기계용접장비 가이드 트랙을 정렬할 때에는 도 3에 도시한 바와 같이 먼저 지그 베이스(10)에 있는 측벽(11)의 롤러(13)와 측벽(11')의 롤러(13') 사이에 기계용접장비 가이드 트랙(2)을 삽입하여 동심도 정렬지그를 설치한다.When aligning the machine welding equipment guide track of the large pipe with the concentricity alignment jig of the large pipe for aligning the machine welding equipment of the present invention, as shown in FIG. 3, the roller 13 of the side wall 11 on the jig base 10 is first shown. And the concentric alignment jig is installed by inserting the mechanical welding equipment guide track 2 between the roller and the roller 13 'of the side wall 11'.

그 다음에 볼트(30b)를 적당히 풀어 제 1링크(31)와 제 2링크(32) 사이의 각도를 조정하여 대형배관(1)의 표면에 닿는 다이얼 게이지(30a)의 위치를 설정한 다음 제 1링크(31)와 제 2링크(32) 사이의 각도가 조정된 각도로 유지되도록 볼트(30b)를 조여 고정한다.Then, loosen the bolt 30b appropriately and adjust the angle between the first link 31 and the second link 32 to set the position of the dial gauge 30a on the surface of the large pipe 1, and then Tighten and fix the bolt 30b so that the angle between the first link 31 and the second link 32 is maintained at the adjusted angle.
