본 발명은 허스롤 구동용 체인 연결장치에 관한 것으로, 보다 상세하게는 소둔로내에서 허스롤을 구동시키는 체인이 절손되었을 때 이를 신속히 보수하여 작업지연을 최소화할 수 있도록 한 허스롤 구동용 체인 연결장치에 관한 것이다.The present invention relates to a chain connecting device for a hearth roll drive, and more particularly, a chain for a hearth roll drive chain that can be quickly repaired to minimize work delay when the chain driving the hearth roll in the annealing furnace is broken. Relates to a device.

일반적으로, 소둔로내에는 스트립 통판을 위한 다수개의 허스롤(Hearth Roll)이 설치된다.Generally, in the annealing furnace, a plurality of Hearth rolls for strip gutters are installed.

이러한 허스롤은 도 1의 예시와 같이, 소둔로(1)의 길이방향을 따라 다수개가 평행하게 설치되며, 허스롤(2)의 축 일단에는 각각 스프라켓(3)이 고정되고, 각 스프라켓(3)은 체인(4)에 의해 연결되며, 그중 어느 하나의 스프라켓(3)은 구동모터(5)와 연결되어 동일방향, 동일속도로 회전하게 구성된다.As shown in FIG. 1, a plurality of such hearth rolls are installed in parallel along the longitudinal direction of the annealing furnace 1, and the sprockets 3 are fixed to one end of the shaft of the hearth roll 2, respectively. ) Is connected by a chain (4), any one of the sprockets (3) is connected to the drive motor 5 is configured to rotate in the same direction, the same speed.

그런데, 이와 같은 허스롤(2)을 통해 장시간 동안 스트립(S) 통판 과정을 거치게 되면 허스롤(2)을 구동하는 체인(4)의 표면에 먼지 등의 이물이 고착되게 되고, 고착정도가 심해지면 과부하가 걸려 체인(4)이 절손되는 사고, 즉 체인(4)을 연결고정하는 세트키(Set Key)가 파손되어 체인(4)이 끊어지는 사고를 유발시키게 된다.However, when the strip (S) mailing process is performed for a long time through the hearth roll 2, foreign substances such as dust are stuck to the surface of the chain 4 driving the hearth roll 2, and the degree of fixation is severe.

동시에, 보조연결구(500)에 마련된 핀(510)을 상기 결속관(620,622)에 각각 삽입하여 고정하게 되면 절손된 부위의 체인(3)을 간편 용이하게 연결할 수 있게 된다.At the same time, when the pins 510 provided in the auxiliary connector 500 are inserted into and fixed to the binding pipes 620 and 622, respectively, the chains 3 of the broken portions can be easily connected.

이후, 결속구(410)를 해체하여 스토퍼(400)를 자유롭게 한 상태에서 걸림구(420)를 누른 채 견인로드(300)를 후퇴시키게 되면 전진되어 있던 견인로드(300)는 다시 후진되어 원래 위치로 되돌아 갈 수 있게 된다.Subsequently, when the binding hole 410 is dismantled and the stopper 400 is freed, and the retracting rod 300 is retracted while pressing the locking hole 420, the towing rod 300 which has been advanced is retracted again to its original position. You can go back to.

이와 같이, 체인(3) 절손시 간단 용이하게 단시간에 이를 보수할 수 있게 되어 휴지기간을 줄여 생산성이 향상되고, 작업시에도 안전한 장점이 있다.As such, when the chain 3 is broken, it can be easily repaired in a short time, thereby reducing the rest period and improving productivity, and there is a safety advantage at work.
