Abstract

PURPOSE: A prompt assembling nut is provided to promote safety in the radiation zone or under the water by promptly assembling many connecting devices used for construction and renewal and to reduce cost by shortening connecting time. CONSTITUTION: A nut is split into two pieces. One part of the nut is integrated with a nut fixing body(11) while the other part is used for adjusting diameter of a female screw. When a nut stator is in an upper portion, a moving nut is movable. For assembling a bolt, the nut stator is lifted up to move the moving nut toward a nut fixing wall(15) and to increase the diameter of the nut by spacing the moving nut from a fixed half-nut. Since the diameter of the nut is increased, the bolt is naturally inserted to a nut thread pitch even without rotation of the bolt. After pushing the bolt to the end, the moving nut is pushed toward the fixed half-nut. And then, the nut stator is lifted down to remove a void between the moving nut and the nut fixing wall. The two half-nuts contact with each other, and function of a single nut is realized. Upon rotation of the bolt, complete connection of the bolt with the nut is secured.

Description

신속 조립용 너트{The method and apparatus of rapid installing nut}Nut for quick assembly {The method and apparatus of rapid installing nut}

원자력 발전설비나 중화학 설비등에는 수 많은 볼트, 너트를 이용하여 기계설비를 체결하고 있다. 그러나 원자력 발전소와 같은 기계설비는 방사선 구역에 설치되어 있는 것이 있어 이들 설비의 신설이나 보수시 작업자에 대한 원자력 방사선피폭이 문제가 된다. 본 발명은 이토록 작업 시간을 단축하는 것이 필요한 볼트/너트 체결기구에 있어 신속하게 조립할 수 있도록 함으로서 작업 시간을 단축하여 방사선 구역에 있는 제 설비, 건설용 비계틀과 같은 임시 사용 구조물, 수중 작업과 같은 난 공사지역에 있는 구조물을 신속하고 안전하게 조립할 수 있도록 하였다.Nuclear power plants and heavy chemical plants use many bolts and nuts to fasten mechanical facilities. However, mechanical facilities such as nuclear power plants are installed in the radiation zone, so the nuclear radiation exposure to workers is a problem when installing or repairing these facilities. The present invention can be quickly assembled in the bolt / nut fastening mechanism that needs to shorten the working time to shorten the working time to make facilities in the radiation zone, temporary use structures such as construction scaffolding, such as underwater work I was able to assemble structures in the construction area quickly and safely.

본 발명은 볼트와 너트를 이용하여 체결하는 것으로서 종래에는 조립시 너트의 일방에서 다른 끝까지 조립을 할 때 볼트를 계속하여 회전 시켜야만 조립이 가능하였다.The present invention is to fasten by using a bolt and a nut in the prior art when assembling from one side of the nut to the other end when assembling it was possible to continue to rotate the bolt.

본 발명은 볼트와 너트를 체결함에 있어 너트의 체결시간과 노동력은 혁신적으로 단축하되 체결후 볼트/너트의 강도 및 회전 방지력등 볼트/너트의 제반 기능은 종전과 동일하게 하는 신속 조립용 너트를 개발하고자 하였다.In the present invention, when fastening the bolt and nut, the fastening time and labor of the nut is innovatively shortened, but the fastening nut for the same function as the bolt / nut strength and rotation prevention force of the bolt / nut after fastening the same as before I wanted to develop.

본 발명은 기존의 나사산이 있는 너트를 반으로 분할하여 한쪽은 다른 부속장치가 있는 너트 고정몸체(11)에 일체화하고, 다른 한쪽은 화살표방향(33)으로 움직일 수 있도록 함으로서 너트 암나사의 직경을 조절할 수 있도록 하였다. 너트 고정자(41)는 화살표(43)와 같이 상하로 움직일 수 있도록 하여 상부에 있을 때는 활동반너트(31)가 움직일 수 있고, 하부에 있을 때는 활동반너트(31)는 전혀 움직이지 못하도록 되어있다. 볼트를 조립할 때 너트고정자(41)를 위로 올리고, 활동 반너트(32)를 너트 고정벽(15)쪽으로 움직여 고정반너트(13)와 활동반너트(31)의 간격을 띄워 너트의 직경을 크게한다. 너트의 직경이 커진 상태가 되었으므로 자연히볼트는 너트의 나사산 부위를 통과할 때 볼트를 회전시키지 않아도 드릴 홈에 환봉이 통과하듯이 자연스럽게 너트 나사산부위로 볼트가 삽입되게 된다. 볼트의 끝까지 볼트를 밀어 넣은 후 활동 반너트(31)를 고정 반너트(13)쪽으로 밀고, 너트 고정자(41)를 아래로 내리면 활동 반너트(31)와 너트 고정벽(15)사이에 빈 공간이 없어져 두 반너트(13,31)가 접촉하게되면서 하나의 단일 너트와 동일한 기능을 수행하게 된다.The present invention adjusts the diameter of the nut female thread by dividing the existing threaded nut in half so that one side is integrated with the nut fixing body 11 having the other accessory and the other side moves in the direction of the arrow 33. To make it possible. The nut stator 41 is able to move up and down as shown by the arrow 43 so that the active half nut 31 can move when it is in the upper part, and the active half nut 31 can not move at all in the lower part. When assembling the bolt, raise the nut stator (41) up and move the active half nut (32) toward the nut fixing wall (15) to offset the fixing half nut (13) and the active half nut (31) to increase the diameter of the nut. . Since the diameter of the nut is increased, the bolt naturally inserts the bolt into the nut thread portion as if the round rod passes through the drill groove without rotating the bolt when passing through the thread portion of the nut. Push the bolt to the end of the bolt and push the active half nut (31) towards the fixed half nut (13), and lower the nut stator (41) downwards to open an empty space between the active half nut (31) and the nut fixing wall (15). This disappears and the two half nuts 13 and 31 come into contact with each other to perform the same function as one single nut.

이때 볼트를 회전시키면 마지막 한바퀴도 돌리지 않은 상태에서 볼트와 너트의 완전한 체결을 보장하게 된다.Rotating the bolt ensures complete bolt and nut tightening without turning the last round.

너트 고정몸체(11)는 활동 반너트를 지지할 수 있도록 고정 반너트와 활동 반너트에 핀홀을 뚫어 고정반너트 핀(14)과 활동 반너트 핀(32)으로 연결하며, 이때 고정반너트 핀(14)과 활동 반너트 핀(32)은 동일한 부품이 된다. 너트 고정자(41) 역시 너트 고정벽(15)에 뚫은 핀홀(17)에 너트 고정자핀(42)을 연결하여 너트 고정자가 상하로 움직일 수 있도록 한다. 너트 고정자(41)와 활동 반너트(31)에는 사람의 손가락으로 쉽게 움직일 수 있도록 손잡이(34, 44)를 구비하였다. 본 도면에는 나타나지 않았지만 활동장치인 너트 고정자(41)와 활동 반너트(31)의 핀부위에는 판 스피링이나 코일 스프링을 두어 활동장치가 항상 닫혀 있는 상태로 유지되도록 하였으며, 너트 고정자에는 홈을 파고, 너트 고정벽에는 볼과 스프링을 두어 너트 고정자(41)가 닫히면 열리지 않도록 하였다. 특히, 볼트/너트의 체결 상태가 장시간 유지되거나 체결 후 분해 가능성이 적은 장치에서는 너트 고정자에 세트 스크류를 두어 너트고정 몸체(11)에 체결함으로서 완전한 체결을 보장하게 하기도 한다.The nut fixing body 11 connects a fixed half nut pin 14 and an active half nut pin 32 by drilling a pin hole in the fixed half nut and the active half nut so as to support the active half nut. 14 and the action half nut pin 32 become the same component. The nut stator 41 also connects the nut stator pin 42 to the pin hole 17 drilled in the nut fixing wall 15 so that the nut stator can move up and down. The nut stator 41 and the activity half nut 31 are provided with handles 34 and 44 so that they can be easily moved by human fingers. Although not shown in the drawing, a plate spring or coil spring is placed on the pins of the nut stator 41 and the action van nut 31, which is an active device, so that the active device is always kept closed. The ball fixing spring was placed on the nut fixing wall to prevent the nut stator 41 from closing. In particular, in a device in which the fastening state of the bolt / nut is maintained for a long time or less likely to be disassembled after fastening, the set screw may be placed on the nut stator to be fastened to the nut fixing body 11 to ensure complete fastening.

본 발명으로 건설, 보수등에 사용되는 많은 체결기구를 신속히 함으로서 고 방사선 구역이나 수중작업등에 안전성을 높혀주고, 체결 시간을 단축함으로서 산업 원가를 절감할 수 있다.In accordance with the present invention, by fastening many fastening mechanisms used for construction, repair, etc., it is possible to reduce industrial costs by increasing safety in high-radiation areas or underwater works, and shortening fastening time.
