본 개시내용은 공구 세트에 관한 것으로, 더욱 상세하게는 하향으로 향하는 가압지지부와 상향으로 향하는 톱니나사가 서로 대칭되게 설계하여 크랙부분을 잡는 힘이 극대화되도록 하여 재 크랙 발생율을 현저히 개선한 특수 볼트로서 크랙을 움켜쥐어 크랙의 진전을 막는 볼트형 락킹 공구에 관한 것이다.The present disclosure relates to a tool set, and more particularly, as a special bolt that significantly improves the rate of occurrence of re-crack by maximizing the force to grasp the crack portion by designing a downwardly facing pressure support portion and an upward facing toothed screw to be symmetrical to each other. It relates to a bolt-type locking tool that grips cracks and prevents cracks from developing.

일반적으로 각종 기계에서의 크랙 발생으로 인한 취약한 부분이나 충격 등에 의해 파손이 발생한 경우 이를 보수하기 위한 일반적인 방법으로는 크랙 부분 혹은 파손된 부분을 맞댄 상태에서 용접을 행하여 두 구성부재를 일체화시키는 작업을 행하게 된다.In general, in the case of damage caused by a weak part or impact caused by a crack in various machines, the general method for repairing it is to perform a work of unifying the two components by performing welding while facing the crack part or the damaged part. do.

상기와 같은 용접은 폭발 위험성 등이 없는 지상 구조물의 경우 큰 문제가 없으나, 선박 등에 설치된 엔진블록, 각종 유체를 이송하는 배관 등에 크랙이 발생한 상태에서 용접하게 되면 용접 열에 의해 크랙 부분이 심하게 변형되는 문제점이 있고, 특히 배관 내부에 인화성 유체가 있을 경우 폭발 우려가 있는 등 다수의 문제점이 있었다.Welding as described above does not have a big problem in the case of ground structures that do not have the risk of explosion, but when welding is performed in a state in which cracks have occurred in engine blocks installed on ships, pipes that transport various fluids, etc., the crack portion is severely deformed by the welding heat. There are a number of problems, such as a risk of explosion, especially when there is a flammable fluid inside the pipe.

최근에는 상기한 문제점을 해결하기 위한 수단으로 볼트를 이용한 보수방법이 제안되고 있다.Recently, as a means to solve the above problems, a repair method using bolts has been proposed.

또한, 경사부(60)가 균열부분에 억지 끼움결합됨으로써 추가적으로 누수나 누유 등을 방지할 수 있다.In addition, since the inclined portion 60 is forcibly fitted to the cracked portion, it is possible to additionally prevent leakage or oil leakage.

도 1, 2를 참조하면 결합부(10) 하단에는 위치선정부(70)가 형성되며, 위치선정부(70)는 일단이 첨예하게 구성되며,Referring to Figures 1 and 2, a position selection unit 70 is formed at the bottom of the coupling unit 10, and the position selection unit 70 is configured with sharp one end,

또한, 위치선정부(70)의 균열부분 삽입시 일정 각도, 균열의 정도에 따라 입사각을 이루도록 구성함으로써 드릴 작업 중 볼트 본체가 미끄러지는 현상을 방지할 수 있다. 따라서 위치선정부(70)는 균열부분에 볼트를 삽입하는 과정에서 미끄러짐을 방지하고, 삽입 완료시 볼트 본체의 위치를 잡아주는 기능을 한다.In addition, when the location selector 70 inserts the cracked portion, it is configured to form an incidence angle according to a certain angle and the degree of the crack, thereby preventing the bolt body from slipping during drilling. Therefore, the positioning unit 70 prevents slipping in the process of inserting the bolt into the cracked portion, and functions to hold the position of the bolt body upon completion of the insertion.

도 2의 위치선정부(70) 부분의 정면도 및 저면도를 참고하면, 위치선정부(70) 일단에 위치한 팁(Tip) 구성은 하단으로 갈수록 직경이 좁아지는 테이퍼 형상으로 형성된다. 또한 결합부(10)로부터 위치선정부(70)까지 드릴(110)이 일부 연장되어 형성되어 있어 균열부분에 삽입될 때 절삭 작용이 용이하게 이루어질수 있다.Referring to the front view and the bottom view of the position selector 70 of FIG. 2, the tip configuration at one end of the position selector 70 is formed in a tapered shape whose diameter decreases toward the lower end. In addition, since the drill 110 is partially extended and formed from the coupling portion 10 to the positioning portion 70, the cutting action can be easily performed when inserted into the crack.

도 1, 2를 참조하면 결합부(10)에 결합되어 하단으로 연장되고 균열부분에 결합부(10) 삽입을 위한 드릴(110)이 장착되는 드릴부(90)가 개시될 수 있다. 드릴부(90)는 크랙부분에 볼트가 삽입될 수 있도록 구멍을 뚫어주는 역할을 한다.Referring to FIGS. 1 and 2, a drill part 90 may be disclosed that is coupled to the coupling part 10 and extends to the lower end, and in which a drill 110 for inserting the coupling part 10 is mounted in the cracked part. The drill part 90 serves to drill a hole so that the bolt can be inserted into the crack part.

이와 같이 드릴부(90)가 볼트형 락킹 공구(100)에 세트로 결합됨으로써, 별도의 드릴 공구를 사용할 필요 없이 락킹 공구 자체만으로 균열부분에 구멍을 뚫고 결합시킬 수 있다.In this way, the drill part 90 is coupled to the bolt-type locking tool 100 as a set, so that it is possible to drill a hole in the crack portion with only the locking tool itself without the need to use a separate drill tool.

도 3에 따라 드릴부(90)에 장착된 드릴(110)이 회전하게 되면서 하단에 결합된 위치선정부(70)가 삭정작업을 통해 균열부분에 구멍을 뚫게 되고, 이에 따라 결합부(10) 및 가압지지부(40)가 균열부분에 삽입되게 되면서 균열부분의 추가 균열을 억제하게 된다.As the drill 110 mounted on the drill part 90 rotates according to FIG. 3, the position selecting part 70 coupled to the lower end makes a hole in the crack through the cutting operation, and accordingly, the coupling part 10 And, as the pressing support portion 40 is inserted into the cracked portion, further cracking of the cracked portion is suppressed.

상기와 같은 본 개시내용의 실시예에 따르면, 하향으로 향하는 가압지지부와 상향으로 향하는 톱니나사가 서로 대칭되게 설계하여 크랙부분을 잡는 힘이 극대화되게 설계하고, 톱니나사의 형태가 상향방향으로 일정 각도를 이루게 하여 크랙을 잡는 구조를 형성하고, 칩의 배출과 삭정작업이 용이하게 스파이럴 홈을 적용하고, 크랙부위로 입사되는 부분의 입사각이 넓이 드릴작업 중 미끄러지는 형상을 줄이고, 칼날이 삭정방향인 시계방향으로 비스듬히 누운 형상으로 설계하여 삭정작업이 용이하도록 하여, 균열 발생 부위의 재 크랙 발생율을 현저히 개선하여 크랙의 진전을 막을 수 있는 효과가 있다.According to the embodiment of the present disclosure as described above, the downwardly directed pressure support part and the upwardly directed toothed screw are designed to be symmetrical to each other, so that the force to hold the crack portion is maximized, and the shape of the toothed screw is designed to be at a certain angle in the upward direction. A structure that catches cracks is formed by forming a structure that catches cracks, and a spiral groove is applied to facilitate chip evacuation and cutting. It is designed in a shape that lies obliquely in a clockwise direction to facilitate cutting, thereby remarkably improving the rate of occurrence of re-cracking at the cracked area, thereby preventing the propagation of cracks.
