본 고안은 볼트등 체결부재의 이완을 방지하기 위하여 삽입 체결 설치되는 록크링을 조여주는 조임공구에 관한 것으로서, 특히 송배전선로에 세워진 철탑을 조립 체결하고 있는 볼트의 이완을 방지수단인 록크링을 보다 양호하게 조이도록 안출된 것이다.The present invention relates to a tightening tool for tightening the lock ring that is inserted and installed to prevent the loosening of the fastening members, such as bolts, and more particularly, the locking ring, which is a means of preventing the loosening of bolts, which is assembled and fastened to a steel tower erected on a transmission and distribution line. It is designed to be tightened well.
종래의 조임공구를 보면, 도면 제5(a)도에서와 같이 중앙에 볼트 관통형 선단부 양측 대향위치에 삽입용 돌기(15') 및 후단부에 이탈 및 역회전 방지용 플랜지를 구비한 회전몸체(10')가, 회전 제어장치를 구비한 손잡이 선단의 원통형 하우징내에 그 선단부위를 일측으로 상당히 돌출시킨 상태로 결합 설치되므로서, 이를 사용시에는 도면 제5(b)도와 같이 양측돌기(15')를 록크링(1)의 플랜지에 형성된 절개홈(100)내에 삽입시킨뒤, 조임공구의 손잡이(21')를 시계방향으로 돌리면 손잡이의 회전력에 의해 오목홈에서 이탈되어 미끄러지면서 회전되며, 반대편 오목홈에 안착됨과 동시 그 조임이 완료되면서 규정토오크로 조여지도록 되었었다.In the conventional tightening tool, as shown in FIG. 5 (a), a rotating body having insertion protrusions 15 'at the opposite sides of the bolt through-type tip at the center and flanges for preventing separation and reverse rotation at the rear end thereof ( 10 ') is installed in the cylindrical housing of the handle tip with the rotation control device in a state where the tip portion is protruded substantially to one side, and when used, both side projections 15' as shown in FIG. 5 (b). Is inserted into the incision groove 100 formed in the flange of the lock ring 1, and when the knob 21 'of the tightening tool is turned clockwise, it is rotated while being deviated from the recess groove by the rotational force of the handle and sliding. As soon as it was seated in the groove, the tightening was completed, it was tightened to the specified torque.
그러나, 이는 조임공구의 회전몸체의 돌기(16')를 록크링(1')에삽입하는데 대한 문제점 및 삽입후 체결결시의 문제점이 대두되었다.However, this has caused problems of inserting the projection 16 'of the rotating body of the tightening tool into the lock ring 1' and problems of fastening after insertion.
상기 혹크링(1')은 즉, 박판재의 금속판을 프레스성형으로 가공한후, 외주의 원호형 플랜지의 부위를 수개의 절개홈(100')을 대칭 형태로 절개 형성한것인바, 상기 회전몸체(10') 선단의 돌기(15')를 절개홈(100')에 삽입시 록크링(1')의 플랜지부 주위를 감싸 보호할수 있는 아무런 가이드 및 결합유지수단이 없어서, 결합상태가 불안정하여 사용중 쉽게 빠지거나 이탈되어 작업성이 나쁘며, 또한 불안정하게 삽입후 불균일한 압력으로 체결시에는 록크링의 변형이 잦아 불량이 발생하는등의 문제뿐만 아니라, 회전몸체를 형성해야 하므로, 제작 및 가공상의 문제점도 아울러 안고 있었다.The hook ring 1 'is formed by cutting a metal plate of a thin plate material by press molding, and then forming a plurality of cutout grooves 100' in a symmetrical form on an arcuate flange portion of the outer circumference. (10 ') There is no guide and engagement holding means that can be wrapped around the flange of the lock ring (1') when inserting the protrusion (15 ') of the tip into the incision groove (100'), so that the engagement state is unstable. It is bad workability because it is easily taken out or detached during use, and when it is unstablely inserted, the locking ring is frequently deformed due to the deformation of the lock ring. There was also a problem.
본 고안은 이와같은 문제점을 해소하기 위하여, 회전몸체의 길이를 하우징의 높이와 거의 같은 길이로 단축시킴과 동시, 선단의 돌기 주위의 록크링이 플랜지 부위와 끼워 맞춤 되는 보호링을 설치하여 록크링에 삽입시 보호링이 록크링이 지지벽 역활을 하도록 하며, 돌기의 이탈방지 및 록크링의 변형을 예방하여 간편하고 안전하게 작업을 할수 있게 한 것으로 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.In order to solve this problem, the present invention shortens the length of the rotating body to about the same length as the height of the housing, and at the same time, installs a lock ring around the protrusion of the tip to be fitted with the flange portion to install the lock ring. When inserted into the protective ring, the lock ring serves as a support wall, prevents the protrusion of the protrusion and prevents the deformation of the lock ring to be able to work easily and safely described in detail by the accompanying drawings as follows.
상부에는 록프핀(26)에 의한 역회전방지용 절개부(12)를 가지는 플랜지(11)와 하방 소정위치 외주면에 오목홈(13) 및 하부에는 하향돌출된 혹크링(1) 조임용 돌기 (15)가 일체로 형성된 회전몸체(10)가 삽입 설치될 하우징(20) 내측연 소정위치로 부터 관통공(22)이 형성된 손잡이부(21)가 일체로 형성되었으며, 상기 관통공(22)에는 상기 회전몸체(10)의 오목홈(13)에 안착될 볼(23)이 압축스프링체(24)에 의해 조정볼트(25)로 체결 고정되는 통상의 것에 있어서, 상기 회전몸체(10)의 오목홈(13) 하방 전둘레에는 돌출부(14)를 형성하고, 상기 돌출부(14)와 형합 설치될 록크링 지지 및 이탈방지용 보호링(30) 내측연 전둘레에 요홈(31)을 형성한 것이다.A flange 11 having an anti-rotation cutout portion 12 by a lock pin 26 at an upper portion thereof, a concave groove 13 at an outer circumferential surface of a lower portion thereof, and a protrusion for tightening a hook ring 1 protruding downwardly at a lower portion thereof 15. ) Is formed integrally with the handle portion 21 in which the through hole 22 is formed from a predetermined position of the inner edge of the housing 20 into which the rotating body 10 in which the insert is formed is integrally formed. In the conventional thing in which the ball 23 to be seated in the recessed groove 13 of the rotary body 10 is fastened and fixed to the adjusting bolt 25 by the compression spring body 24, the recessed groove of the rotary body 10. (13) The lower front circumference is formed with a protrusion 14, and the groove 31 is formed at the inner circumference of the inner edge of the lock ring support and separation prevention protection ring 30 to be installed in combination with the protrusion 14.
이와같이 구성된 본 고안은 볼트체겸부위에 볼트를 삽입하고 볼트와 너트를 체결한 상태에서 록트링(1)의 구멍 내주연단은 마치 너트와 같이 비틀려져 있어 볼트에 삽입하고 손으로 돌려 너트에 밀착시킨후, 볼트 및 록크링(1)의 규격에 해당하는 조임공구를 선택하고 회전 몸체(10) 하방의 돌기(15)를 록크링(1)의 홈에 끼운다.According to the present invention, the bolt inner part is inserted into the bolt body and the nut and the nut are fastened to the inner circumferential end of the lock ring (1) as if it is twisted like a nut. , Select the tightening tool corresponding to the standard of the bolt and the lock ring (1) and insert the projection (15) below the rotating body (10) into the groove of the lock ring (1).
이때, 회전몸체(10)의 하방돌기(15)을 보호링(30)이 감싸고 있어 공구의 미끄럼으로 인한 이탈이 없이 정확하게 삽입이 이루어진다.At this time, the lower ring protrusion 15 of the rotating body 10 is wrapped around the protective ring 30 is accurately inserted without the departure due to the sliding of the tool.
록크링(1)과 돌기(15)가 형합된 상태에서 손잡이를 잡고 시계방향으로 돌리게되면 회전몸체(10)이 오목홈(13)에 안착된 볼(23)에 의해 회전력을 전달받아 록크링(1)이 조여지며 허용압력으로 죄어졌을 때에 손잡이(21)내부에 합축스프링체(24)가 압축되면서 오목홈(13)에서 볼(23)이 이탈되면서 계속되는 회전력에 의하여 볼(23)이 회전몸체(10)의 외주면을 따라 미끄러짐과 동시 반대편에 위치한 오목홈(13)에 안착되면 규정된 압력으로 조여지게 되어 볼트의 이완을 방지하는 것으로 본 고안의 목적에 만족하는 것으로, 해제시에는 상기 손잡이를 반시계 방향으로 돌리게 되면 오목홈(13) 내에 안착된 볼(23)이 키작용하여 록크링(1)이 해제되고 너트를 해제시켜 분리하게 되는 것이다.When the lock ring (1) and the projection (15) is held in a state in which the handle is rotated in the clockwise direction, the rotating body (10) receives the rotational force by the ball (23) seated in the concave groove (13). 1) is tightened and tightened to the allowable pressure when the coaxial spring body 24 is compressed in the handle 21, the ball 23 is rotated by the rotational force that continues as the ball 23 is released from the concave groove 13 Slip along the outer circumferential surface of (10) and is seated in the concave groove 13 located on the opposite side at the same time is tightened to the prescribed pressure to prevent the loosening of the bolt to satisfy the object of the present invention, when released the handle When turned counterclockwise, the ball 23 seated in the concave groove 13 acts as a key to release the lock ring 1 and release the nut to separate it.
이상과 같이 본 고안은, 회전몸체(10)의 돌기(15) 외부로 보호링(30)이 설치되어 보호링(30)이 삽입된 돌기(15) 및 록크링(1)을 감싸고 있어 공구가 록크링(1)으로부터의 이탈을 방지하여 정확하게 회전력을 전달할수 있어 록크링(1)의 변형 및 마모를 예방하여 록크링의 수명연장 및 작업성을 향상시킬 수 있는 매우 유용한 고안이다.As described above, the present invention, the protective ring 30 is installed to the outside of the projection 15 of the rotating body 10, the protective ring 30 is wrapped around the protrusion 15 and the lock ring 1 is inserted into the tool It is a very useful design that can prevent the departure from the lock ring (1) to accurately transmit the rotational force to prevent deformation and wear of the lock ring (1) to improve the life extension and workability of the lock ring.
