Description
본 발명은 원자로 상부 내장물의 체결볼트 무게보상장치에 관한 것으로서, 더욱 상세하게는 원전의 핵연료 재장전 작업시 UGS(상부 내장물)를 인양할 때 상기 상부 내장물과 그 내장물을 체결하는 인양구조체의 리프트 볼트에 걸리는 부하를 감소시키도록 하는 원자로 상부 내장물의 체결볼트 무게보상장치에 관한 것이다.The present invention relates to a fastening bolt weight compensation device of the upper interior of the reactor, and more particularly, the lifting structure for fastening the upper interior and the interior when lifting the UGS (upper interior) during nuclear fuel reload operation. A fastening bolt weight compensator of a nuclear reactor upper interior unit to reduce the load on the lift bolt of the present invention.
도 1 및 도 2 에 도시된 바와 같이 인양구조체(10)의 리프트 볼트(12)와 상부 내장물을 체결, 분리시 모든 부하(약70Kg)가 리프트 볼트(12)와 상부 내장물 암나사에 전달이 되므로 나사산에 크롬 코팅된 면의 마모가 빨리 진행되는 문제가 있다.As shown in FIGS. 1 and 2, when the lift bolt 12 of the lifting structure 10 is fastened to the upper internals, all loads (about 70 kg) are transferred to the lift bolts 12 and the internal internal threads of the lifting structure 10. Therefore, there is a problem that the wear of the surface coated with chrome proceeds quickly.
그 리프트 볼트(12)를 스테이션어리 드레드(Stationary thread)에 조립, 분리시 작업장소가 협소하여 한 사람만이 작업할 수 있으므로 작업도중 칼럼볼트(11)하부에 구성된 리프트 볼트(12) 로우어 렌치(13) 및 어퍼 렌치(14)의 무게를 이기지 못하여 이러한 구성요소가 상부 내장물에 떨어져 암나사를 손상시킬 수 있는 문제가 있었다.When the lift bolt 12 is assembled and detached to the stationary thread, the work place is narrow and only one person can work, so the lift bolt 12 lower wrench formed at the bottom of the column bolt 11 is in operation. There was a problem that these components could fall on the upper internals and damage the female threads because the weight of the 13 and the upper wrench 14 could not be overcome.
또한 리프트 볼트 취급과정에서 리프트 볼트 핀에 로우어 및 어퍼 렌치의 무게가 얹히므로 마모가 되어 시간이 경과하면서 파손되는 문제가 있었다.In addition, since the weight of the lower and upper wrench is placed on the lift bolt pin during the handling of the lift bolt, there is a problem that the wear is damaged over time.
따라서, 본 발명은 상기와 같은 제반문제를 해결하기 위해 창출된 것으로서, 그 목적은 원전의 핵연료 재장전 작업시 UGS(상부 내장물)를 인양할 때 상기 상부 내장물과 그 내장물을 체결하는 인양구조체의 리프트 볼트에 걸리는 부하를 감소시키도록 하는 원자로 상부 내장물의 체결볼트 무게보상장치를 제공함에 있다.Therefore, the present invention has been created to solve the above problems, the object is to lift the upper internals and the internals when lifting the UGS (upper internals) during nuclear fuel reload operation of nuclear power plants The present invention provides a fastening bolt weight compensator for the upper portion of a reactor to reduce the load on the lift bolt of the structure.
상기 목적을 달성하기 위해 본 발명은, 인양구조체(10)의 칼럼볼트(11) 상부에 고정 설치되고, 컨트롤러(40)의 제어신호에 의해 공압발생수단(30)을 작동시켜 칼럼볼트(11) 하단에 상부 내장물(UGS)을 고정하기 위해 고정 설치된 리프트 볼트(12)와 로우어 및 어퍼 렌치(13)(14)의 하중부하를 저감하기 위해 실린더 구조체(20)를 구성하는 특징을 갖는다.In order to achieve the above object, the present invention is fixed to the upper column bolt 11 of the lifting structure 10, by operating the pneumatic generating means 30 by the control signal of the controller 40 column bolt 11 The cylinder structure 20 is configured to reduce the load of the lift bolt 12 and the lower and upper wrenches 13 and 14 fixedly installed to fix the upper internal part UGS at the lower end.

본 발명의 구성은, 인양구조체(10)의 칼럼볼트(11) 상부에 고정 설치되고, 컨트롤러(40)의 제어신호에 의해 공압발생수단(30)을 작동시켜 칼럼볼트(11) 하단에 상부 내장물(UGS)을 고정하기 위해 고정 설치된 리프트 볼트(12)와 로우어 및 어퍼 렌치(13)(14)의 하중부하를 저감하기 위해 실린더 구조체(20)를 구성하도록 하였다.The configuration of the present invention is fixed to the upper column bolt 11 of the lifting structure 10, by operating the pneumatic generating means 30 in accordance with the control signal of the controller 40 built-in upper portion of the lower column bolt 11 The cylinder structure 20 was configured to reduce the loads of the lift bolts 12 and the lower and upper wrenches 13 and 14 fixedly installed to fix the water UGS.
이에 따른 상기 실린더 구조체(20)는 인양구조체(10)의 고정단에 고정 설치되는 실린더 튜브(21)와, 상기 실린더 튜브(21)내에 습동결합되는 칼럼볼트(11)의 상단에 고정 설치되는 피스톤로드(22)와, 상기 피스톤로드에 일체로 형성되는 피스톤(23) 및 공압발생수단(30)으로부터 공압을 실린더 튜브(21) 내부로 유입/출시킬 수 있는 공압흐름구조인 니쁠(24)로 구성하되, 상기 실린더 구조체(20)는 항상 일정한 압의 유지를 위해 안전밸브(25)가 부설되도록 하였다.Accordingly, the cylinder structure 20 has a cylinder tube 21 fixedly installed at the fixed end of the lifting structure 10 and a piston fixedly installed at the upper end of the column bolt 11 slidably coupled to the cylinder tube 21. From the rod 22, the piston 23 formed integrally with the piston rod and the pneumatic generating means 30 to the nipple 24, which is a pneumatic flow structure that can flow the air pressure into the cylinder tube 21 / out The cylinder structure 20 is configured such that the safety valve 25 is always installed for maintaining a constant pressure.
상기와 같이 구성된 본 발명의 작용을 설명한다.The operation of the present invention configured as described above will be described.
상부 내장물의 인양을 위한 인양 구조체(10)의 칼럼볼트(모두 3곳;11)에 각각 본 발명에 따른 실린더 구조체(20)를 설치하여 약2Kg/㎠로 조절하면 70Kg정도의 무게를 보상하여 체결시 리프트 볼트(12)를 분리하여 내린 후 상부 내장물의 암나사에 체결한다.When the cylinder structure 20 according to the present invention is installed on the column bolts (all three places; 11) of the lifting structure 10 for lifting the upper internal parts, respectively, and adjusted to about 2Kg / cm 2, the weight of about 70Kg is fastened and fastened. Remove the lift bolt 12 and lower it, then fasten it to the internal thread of the upper internals.
이 때 컨트롤러(40)를 작동시켜 공압발생수단(30)으로부터의 공압을 실린더 구조체(20)의 피스톤로드(22)를 상향시키도록 유입시키면서 무게를 보상하게 되는데, 안전밸브(25)는 일정이상의 공압이 발생되면 곧바로 외기로 배출시킨다.At this time, by operating the controller 40 to compensate the weight while introducing the pneumatic pressure from the pneumatic generating means 30 to raise the piston rod 22 of the cylinder structure 20, the safety valve 25 is more than a predetermined As soon as pneumatic pressure is generated, vent it to the outside air.
한편, 상부 내장물의 안착후 리프트 볼트(12)를 상부 내장물 암나사에서 분리하여 스토리지 드레드에 조립할 때에도 항상 관내에 일정한 압력을 유지하여 상기 리프트 볼트 집합체의 무게를 보상한다.On the other hand, even after the mounting of the upper interior of the lift bolt 12 is separated from the upper internal thread of the internal thread, even when assembling to the storage thread always maintain a constant pressure in the tube to compensate the weight of the lift bolt assembly.
이상에서 설명한 본 발명은 전술한 실시예 및 도면에 의해 한정되는 것은 아니고, 본 발명의 기술적 사상을 벗어나지 않는 범위내에서 여러 가지 치환, 변형 및 변경이 가능함은 본 발명이 속하는 기술 분야에서 통상의 지식을 가진 자에게 있어 명백할 것이다.The present invention described above is not limited to the above-described embodiments and drawings, and various substitutions, modifications, and changes can be made without departing from the technical spirit of the present invention. It will be apparent to those who have
이상에서와 같은 본 발명을 적용하게 되면, 상부 내장물을 지지하는 리프트 볼트, 로우어 및 어퍼 렌지의 무게를 보상할 수 있기 때문에 이러한 구조물의 파손을 방지할 수 있을 뿐만 아니라 안전밸브의 추가적인 구성에 의해 공압계통의 관내에 항상 일정한 압력이 유지되어 기계의 신뢰성을 기할 수 있다.By applying the present invention as described above, it is possible to compensate for the weight of the lift bolt, the lower and the upper range for supporting the upper interior, it is possible not only to prevent the damage of these structures but also to the additional configuration of the safety valve As a result, a constant pressure is always maintained in the pipe of the pneumatic system, thereby ensuring the reliability of the machine.
