도 3 및 도 4에 도시된 바와 같이, 유도롤러부(100)는 허스롤(30)의 삽입구(34) 인접위치에 설치되는 것으로 가이드레일(500)상에 이를 따라 이동가능한 받침대(110)가 구비되고, 상기 받침대(110)에는 전후방향으로 회전가능한 'ㄱ'형상의 지지대(120)가 축고정된다.As shown in FIGS. 3 and 4, the guide roller unit 100 is installed at a position adjacent to the insertion hole 34 of the hearth roll 30, and a pedestal 110 movable along the guide rail 500 is provided. It is provided, the support 110 is axially fixed to the '120' shaped support rotatable in the front and rear direction.

상기 지지대(120)의 절곡된 상단에는 새들형상의 유도롤러(150)가 회전가능하게 축설되며, 상기 지지대(120)의 하단부에는 상기 받침대(110)에 고정되고 고정핀(140)에 의해 지지대(120)의 회전각을 조절할 수 있는 브라켓(130)이 설치된다.The saddle-shaped induction roller 150 is rotatably arranged on the bent upper end of the support 120, the lower end of the support 120 is fixed to the pedestal 110 and supported by the fixing pin 140. Bracket 130 that can adjust the rotation angle of 120 is installed.

따라서, 허스롤(30) 취외시 허스롤(30)의 인출각도에 따라 이를 지지하는 상기 유도롤러(150)의 경사각을 상기 고정핀(14)과 브라켓(130)을 통해 조절할 수 있게 된다.Therefore, the inclination angle of the induction roller 150 supporting it according to the drawing angle of the hearth roll 30 when the hearth roll 30 is removed can be adjusted through the fixing pin 14 and the bracket 130.

클램프부(200)는 도 4의 도시와 같이, 허스롤(30)의 샤프트(32)를 지지할 수 있는 'Y'형상의 강철로 된 탄성지지편(220)이 구비되고, 상기 탄성지지편(220)의 하단면에는 지지로드(240)가 고정된다.As shown in FIG. 4, the clamp unit 200 is provided with an elastic support piece 220 made of 'Y'-shaped steel capable of supporting the shaft 32 of the hearth roll 30. The support rod 240 is fixed to the bottom surface of the 220.

지지로드(240)는 가이드(230) 및 조정판(210)을 관통하여 배설되고 그 단부에는 작동아암(250)이 축고정된다.The support rod 240 is disposed through the guide 230 and the adjusting plate 210, and the operating arm 250 is axially fixed at the end thereof.

상기 조정판(210)의 상면에는 상기 탄성지지편(220)이 안착되는 가이드(230)가 고정되는 바, 가이드(230)의 양측 내면에는 상기 탄성지지편(220)의 외측면이구름접촉되는 가이드롤(232)이 설치된다.The guide 230 on which the elastic support piece 220 is seated is fixed to an upper surface of the adjustment plate 210, and the outer surface of the elastic support piece 220 is cloud-contacted to both inner surfaces of the guide 230. The roll 232 is installed.

상기 조정판(210)의 배면에는 고정브라켓(256)에 의해 원통형상의 커버(254)가 고정되며, 상기 커버(254) 내부에는 회전가능한 작동축(252)이 고정된다.A cylindrical cover 254 is fixed to the rear surface of the adjusting plate 210 by a fixing bracket 256, and a rotatable working shaft 252 is fixed inside the cover 254.

상기 작동축(252)의 양단에는 작동아암(250)이 직교되게 고정되고, 상기 작동아암(250)은 지지로드(240)에 연결된다.Both ends of the operating shaft 252 is fixed to the operation arm 250 orthogonally, the operation arm 250 is connected to the support rod 240.

또한, 작동축(252)의 중앙부인 상기 커버(254)의 내부에는 래치기어(258)가 상기 작동축(252)과 함께 회전가능하게 설치되고, 상기 래치기어(258)에는 상기 커버(254)를 관통하여 래치(262)가 설치된다.In addition, a latch gear 258 is rotatably installed together with the operating shaft 252 in the cover 254, which is a central portion of the operating shaft 252, and the cover 254 is provided in the latch gear 258. The latch 262 is installed therethrough.

래치(262)의 일측 상면에는 레버(264)가 고정되며, 래치(262)의 타측 상면에는 스프링샤프트(260)가 연결된다.The lever 264 is fixed to one upper surface of the latch 262, and the spring shaft 260 is connected to the other upper surface of the latch 262.

따라서, 상기 스프링샤프트(260)는 상기 래치(262)가 항상 래치기어(258)에 치합되도록 하여 상기 래치기어(258)는 항상 일방향, 도시된 바에 의하면 시계방향으로만 회전가능하게 하여준다.Thus, the spring shaft 260 ensures that the latch 262 is always engaged with the latch gear 258 so that the latch gear 258 is always rotatable in one direction, as shown in the clockwise direction.

만약, 반시계방향으로 회전시키고자 할 경우에는 레버(264)를 움직여 스프링샤프트(260)의 인장력을 극복하면서 래치(262)를 래치기어(258)로부터 해제시키면 가능하다.If it is desired to rotate in the counterclockwise direction, the lever 264 may be moved to release the latch 262 from the latch gear 258 while overcoming the tension of the spring shaft 260.

높낮이조절부(300)는 도 3의 도시와 같이, 베이스부(400)의 베이스판(410)에 형성된 관통공(430)과 삽입홈(440)속으로 각각 잭스크류(330)와 가이드봉(340)이 삽입되고, 잭스크류(330) 및 가이드봉(340)의 상단에는 지지플레이트(350)가 고정된다.As shown in FIG. 3, the height adjusting part 300 is a jackscrew 330 and a guide rod into the through hole 430 and the insertion groove 440 formed in the base plate 410 of the base part 400, respectively. 340 is inserted, the support plate 350 is fixed to the top of the jackscrew 330 and the guide rod 340.

상기 지지플레이트(350)의 상면에는 고정블럭(360)이 결합되고, 상기 고정블럭(360)에는 상술한 클램프부(200)의 조정판(210)이 고정된다.The fixing block 360 is coupled to an upper surface of the support plate 350, and the adjustment plate 210 of the clamp unit 200 is fixed to the fixing block 360.

잭스크류(330)의 일측에는 베벨기어(322)가 형성되고, 상기 베벨기어(322)는 상기 베이스판(410)에 고정된 베벨기어(320)와 치합된다.A bevel gear 322 is formed at one side of the jack screw 330, and the bevel gear 322 is engaged with the bevel gear 320 fixed to the base plate 410.

상기 베벨기어(320)의 일단에는 작동핸들(310)이 고정된다.An operation handle 310 is fixed to one end of the bevel gear 320.

따라서, 상기 작동핸들(310)을 회전시킴으로써 한쌍의 베벨기어(320,322)에 의해 잭스크류(330)가 회전되고 상기 잭스크류(330)의 회전에 의해 지지플레이트(350)가 승하강가능하게 된다.Accordingly, the jack screw 330 is rotated by the pair of bevel gears 320 and 322 by rotating the operation handle 310, and the support plate 350 is lowered by the rotation of the jack screw 330.

베이스부(400)는 상기 가이드레일(500)을 따라 그 상면에 배설된 슬라이딩바(420)에 베이스판(410)이 안착되어 활주가능하게 설치된다.The base unit 400 is slidably installed with the base plate 410 seated on the sliding bar 420 disposed on the upper surface of the guide rail 500.

이러한 구성으로 이루어진 본 발명은 다음과 같이 작동된다.The present invention made up of such a configuration works as follows.

허스롤(30)의 교체를 위해 먼저 가이드레일(500)상에 안착된 유도롤러부(100)를 소둔로(1)의 삽입구(34)에 인접하도록 밀착시켜 유동되지 않도록 고정한다.In order to replace the hearth roll 30, first, the guide roller part 100 seated on the guide rail 500 is fixed to be adjacent to the insertion hole 34 of the annealing furnace 1 so as not to flow.

이때, 허스롤(30)의 롤 샤프트(32)가 용이하게 취외될 수 있도록 유도롤러(150)의 각도를 고정핀(140)과 브라켓(130)을 이용하여 조절한다.At this time, the angle of the guide roller 150 is adjusted using the fixing pin 140 and the bracket 130 so that the roll shaft 32 of the hearth roll 30 can be easily removed.

조절이 완료되면, 베이스부(400)의 베이스판(410)을 슬라이딩바(420)를 따라 상기 유도롤러부(100)측으로 밀착시킨다.When the adjustment is completed, the base plate 410 of the base 400 is in close contact with the guide roller unit 100 along the sliding bar 420.

이 상태에서, 높낮이조절부(300)의 작동핸들(310)을 회전시켜 클램프부(200)가 허스롤(30)의 롤 샤프트(32)와 거의 평행하게 유지되도록 조절한다.In this state, the operation handle 310 of the height adjustment unit 300 is rotated so that the clamp unit 200 is maintained to be substantially parallel to the roll shaft 32 of the hearth roll 30.

조절이 완료되면, 허스롤 교환치구를 이용하여 허스롤(30)을 취외시키게 되는바, 취외되던 허스롤(30)은 유도롤러부(100)의 유도롤러(150)를 따라 원활하게 인출되면서 그 샤프트(32)가 상기 클램프부(200)의 탄성지지편(220)에 안착된다.When the adjustment is completed, the hearth roll 30 is removed by using the hearth roll exchange jig, and the outboard hearth roll 30 is smoothly drawn out along the induction roller 150 of the induction roller unit 100. The shaft 32 is seated on the elastic support piece 220 of the clamp unit 200.

중량물인 허스롤(30)의 자중에 의해 탄성지지편(220)은 그 외면과 접촉된 가이드롤(232)과 구름접촉되면서 하강하게 되고, 탄성지지편(220)의 하강에 의해 지지로드(240)와 연결된 작동아암(250)이 유동되어 작동축(252)을 회전시키게 된다.The elastic support piece 220 is lowered by rolling contact with the guide roll 232 which is in contact with the outer surface by the weight of the hearth roll 30 which is a heavy object, and the support rod 240 is lowered by the lowering of the elastic support piece 220. Operating arm 250 is connected to the flow is to rotate the operating shaft (252).

작동축(252)의 회전에 따라 래치기어(258)가 시계방향으로 회전되면서 래치(262)에 의해 회전된 상태로 고정되어 샤프트(32)를 유동없이 고정하게 된다.As the operating shaft 252 rotates, the latch gear 258 is rotated in the clockwise direction and fixed by the latch 262 to fix the shaft 32 without flow.

여기에서, 허스롤이 교체된 후 소둔로(1)에 삽입되면 하강되어 있던 지지로드(240)는 레버(264)를 들어올림으로써 원위치로 복귀되게 된다.Here, when the hearth roll is replaced and then inserted into the annealing furnace 1, the supporting rod 240 which has been lowered is returned to its original position by lifting the lever 264.

즉, 탄성지지편(220)이 최대한 오므려들어 있는 상태이므로 래치(262)의 고정력이 상실되는 순간 탄성지지편(220)은 원래 상태로 복귀되려고 하고 그 탄성력에 의해 지지로드(240)가 상향이동되면서 래치기어(258)도 원위치로 회전되어 복귀되게 된다.That is, since the elastic support piece 220 is fully retracted, the elastic support piece 220 tries to return to its original state when the fixing force of the latch 262 is lost, and the support rod 240 is moved upward by the elastic force. As the latch gear 258 is moved, the latch gear 258 is rotated to its original position and returned.

롤 샤프트(32)가 정확하게 안착되면 베이스부(410)를 유도롤러부(100) 대향방향으로 활주시켜 허스롤(30)을 최종적으로 취외하게 된다.When the roll shaft 32 is correctly seated, the base part 410 is slid in the direction opposite to the guide roller part 100 to finally take out the hearth roll 30.

취부시에는 상술한 반대작동으로 이루어지며, 이때에도 높낮이조절부(300)의 작동핸들(310)과 지지대(120)의 경사각을 적절히 조정함으로써 허스롤(30)의 취부를 용이하게 할 수 있다.When the mounting is made in the above-described reverse operation, it is also possible to facilitate the mounting of the hearth roll 30 by adjusting the inclination angle of the operation handle 310 and the support 120 of the height adjustment unit 300 properly.

이상에서 상세히 설명한 바와 같이, 본 발명은 고열이 잔존하는 소둔로의 허스롤을 교체할 때에 기계적인 수단을 이용하여 신속하고 안전하며 용이하게 취외 및 취부할 수 있으므로 작업효율의 증대, 작업자의 안전성 확보는 물론 생산성을 향상시키는 효과를 제공한다.As described in detail above, the present invention can be quickly and safely and easily removed and mounted by using a mechanical means when replacing the hearth roll of the annealing furnace in which high heat remains, thereby increasing work efficiency and ensuring worker safety. Of course, it provides the effect of improving productivity.
