Description

노내 계측기 밀봉하우징 수직도 측정용 지그장치{Alignment Jig for Incore instrument seal housing}TECHNICAL FIELD [0001] The present invention relates to a jig for measuring the vertical extent of an enclosed housing,

본 발명은 원력발전소의 원자로 노내계측기 밀봉하우징 교체시 시공 후 수직도를 측정하기 위한 노내계측기 밀봉하우징 수직도 측정 지그장치에 관한 것이다.The present invention relates to a jig device for measuring the verticality of an in-furnace instrument sealed housing when measuring the degree of vertical post-installation when replacing a sealed housing of a nuclear power reactor in a nuclear power plant.

종래의 경우, 별도의 전용장비가 개발되어 있지 않아 적용상 어려움이 있고, 용접부와 측정지점 사이는 철판이 가로막혀 있는 관계로 일반적인 방식으로는 측정이 불가능하고, 또한 배관의 정렬상태를 다이얼게이지로 관리하는 별도의 표준기구도 없으며, 주로 외경의 단차량을 측정하는 방식이 있으나 이와 같은 종래의 방식으로는 시방서의 요건을 충족할 수 없는 문제가 발생하고 있다.In the conventional case, there is a difficulty in application because a separate dedicated equipment has not been developed. Since the steel plate is blocked between the welded portion and the measurement point, the measurement can not be performed by a general method and the alignment state of the pipe is measured by a dial gauge There is no separate standard mechanism for managing the vehicle, and there is a method of measuring the outer diameter of the vehicle. However, such a conventional method has a problem that the specification can not be satisfied.
