In the coil car to be transferred to the coil car, the shock absorbing spring is mounted on the coil car roller installed on the upper part of the coil car to prevent slippage and end distortion of the hot rolled coil seated on the upper part of the coil car roller. To a given name.

종래의 기술을 도 1을 참조하여 설명하면 다음과 같다.The prior art is described with reference to FIG. 1 as follows.

일반적으로, 열연공장의 권취기에서 권취가 완료된 열연코일(6)은 컨베이어를 타고 적하장으로 이송된다.In general, the hot rolled coil 6, which has been wound up in a winding machine of a hot rolling mill, is transferred to a loading dock by a conveyor.

상기 열연코일(6)을 권취로부터 컨베이어로 이송하는 작업은 코일카(7)에 의하여 이루어지며, 상기 코일카(7)는 상기 열연코일(6)이 권취가 완료되었을 때 그 하부로 유입되어 이를 들어낸다.The operation of transferring the hot rolled coil 6 from the winding to the conveyor is performed by the coil car 7, and the coil car 7 flows into the lower part of the hot rolled coil 6 when the winding is completed. Lift out.

상기 작업을 상세히 설명하면, 상기 코일카(7)의 측부에 설치되어 있는 수평 구동실린더(4a)의 구동으로 코일카(7)가 권취완료된 열연코일(6)의 하부로 위치되면 상기 코일카(7)의 하부에 설치된 상하 구동실린더(4b)의 구동으로 롤 프레임(3)이 승강된다.In detail, the coil car 7 is positioned below the wound hot rolled coil 6 by the driving of the horizontal drive cylinder 4a installed at the side of the coil car 7. The roll frame 3 is lifted and lowered by the drive of the up-and-down drive cylinder 4b provided in the lower part of 7).

이 때, 상기 롤 프레임(3)의 상부에는 롤 베어링 블록(2)에 의해 지지되는 2개의 코일카 롤러(1)가 설치되어 상기 열연코일(6)을 지지하면서 들어낸다.At this time, two coil car rollers 1 supported by the roll bearing block 2 are installed on the upper part of the roll frame 3 and lift out while supporting the hot rolled coil 6.

그런데, 상기 열연코일(6)이 코일카 롤러(1)에 안착되어 이송되는 과정에서 코일카 롤러(1)는 구동실린더(4a,4b)의 동력으로 인해 유동하는 반면 열연코일(6)은 정지된 상태를 유지하려는 관성의 힘이 작용하여 코일카 롤러(1)의 상부에서 미끄러지게 된다.However, the coil car roller 1 flows due to the power of the driving cylinders 4a and 4b while the hot rolled coil 6 is seated on the coil car roller 1, and the hot rolled coil 6 stops. The inertial force that tries to maintain the closed state is applied to slip on the upper portion of the coil car roller (1).

특히, 열연코일(6)의 폭과 하중을 감안하여 상기 슬라이스 롤(10)의 개수는분할된 6개의 슬라이스 롤(10)로 밀착시키는 것이 바람직하며, 아울러 상기 스프링(12)이 각 슬라이스 롤(10)에 8개가 삽입되도록 슬라이스 롤 홈(11) 및 회전축 홈(13)이 형성되는 것이 바람직하다.In particular, in view of the width and the load of the hot rolled coil 6, the number of the slice rolls 10 is preferably in close contact with the six slice rolls 10 divided, and the spring 12 is each slice roll ( It is preferable that the slice roll grooves 11 and the rotation shaft grooves 13 are formed so that eight pieces are inserted in 10).

이러한 구성으로 이루어진 본 발명의 작동관계는 다음과 같다.The operating relationship of the present invention made of such a configuration is as follows.

도 4에서 도시된 바와 같이, 코일카(7)의 상부로 열연코일(6)이 안착되지 않았을 때는 회전축(5)에 삽입되어진 슬라이스 롤(10)들은 평행하게 밀착되어 본 발명에 따른 코일 슬립 방지용 분할형 코일카 롤러와 종래의 코일카 롤러(1)는 그 형상이 동일하게 보여진다.As shown in FIG. 4, when the hot rolled coil 6 is not seated on the upper portion of the coil car 7, the slice rolls 10 inserted into the rotating shaft 5 are closely contacted in parallel to prevent coil slip according to the present invention. The split coil car roller and the conventional coil car roller 1 are seen to have the same shape.

아울러, 상기 슬라이스 롤(10)에 내장되어 있는 스프링(12)은 상부로부터 하중을 받지 않으므로 초기의 형태를 유지한다.In addition, the spring 12 embedded in the slice roll 10 does not receive a load from the top to maintain the initial shape.

하지만, 도 5에서 도시된 바와 같이 본 발명에 따른 코일 슬립 방지용 분할형 코일카 롤러의 상부로 열연코일(6)이 안착될 경우, 상기 열연코일(6)과 접촉되는 슬라이스 롤(10)들은 그 하중으로 인하여 일제히 하부로 내려 앉게 된다.However, as shown in FIG. 5, when the hot rolled coil 6 is seated on the split coil car roller for preventing the coil slip according to the present invention, the slice rolls 10 which are in contact with the hot rolled coil 6 are Due to the load, they all sit down together.

이는, 슬라이스 롤(10)마다 그 내부에 장착되어진 스프링(12)의 탄성으로 인한 것이며, 아울러 상기 내려 앉은 슬라이스 롤(10)의 양단에 위치되는 슬라이스 롤(10)은 열연코일(6)을 고정하는 스토퍼 역할을 한다.This is due to the elasticity of the spring 12 mounted therein for each slice roll 10, and the slice rolls 10 positioned at both ends of the downed slice roll 10 fix the hot rolled coil 6. It acts as a stopper.

따라서, 상기 스토퍼 역할을 하는 슬라이스 롤(6)로 인하여 열연코일(6)은 코일카(7)의 구동실린더(4a,4b)로부터 유발되는 진동에도 불구하고 유동되거나 미끄러지지 않는다.Accordingly, the hot rolled coil 6 does not flow or slip due to the slice roll 6 serving as the stopper, despite the vibration caused by the driving cylinders 4a and 4b of the coil car 7.

이상에서 상세히 설명한 바와 같이, 본 발명에 따른 코일 슬립 방지용 분할형 코일카 롤러에 열연코일이 안착되면 구동실린더로부터 발생되는 동력으로 인하여 코일카 자체는 유동되더라도 상기 열연코일은 유동되지 않는다.As described in detail above, when the hot rolled coil is seated on the split type coil car roller for preventing the coil slip according to the present invention, the hot rolled coil does not flow even though the coil car itself flows due to the power generated from the driving cylinder.
