작업테크(34)에 서로 대칭되도록 고정 설치되는 한쌍의 지지브래킷(30)에는 상하로 길게 형성된 안내홀(36)이 형성되어 있고, 이 안내홀(36)에 터치구동롤(31)의 축 양단이 끼워지게 된다.A pair of support brackets 30 fixed to each other to be symmetrically installed in the work technique 34 are formed with guide holes 36 that are formed to extend up and down, and the guide holes 36 are provided at both ends of the shaft of the touch driving roll 31. Will be fitted.

이때, 터치구동롤(31)은 웨이트롤(29)의 안착시 완충봉(33)의 완충스프링(32)을 압축하면서 안내홀(36)을 따라 하강됨으로써 웨이트롤의 안착충격을 완충하게 된다.At this time, the touch driving roll 31 is lowered along the guide hole 36 while compressing the shock absorbing spring 32 of the buffer rod 33 when the wait trolley 29 is seated to cushion the seat shock of the wait trolley.

그리고, 주권후크(6)에 결합핀(27)을 중심으로 편심 회전되면서 주권후크의 입구를 가로 막도록 설치되는 잠금대(20)는 그 후방측단에 웨이트롤(29)이 설치되어 있고, 주권후크의 일측에 용접된 스토퍼(28)에 의해 편심회전이 제한되도록 설치되어 있다.In addition, the lock 20 is installed to block the inlet of the sovereign hook while being eccentrically rotated around the coupling pin 27 on the sovereign hook 6, and a wait trolley 29 is installed at the rear end thereof. The stopper 28 welded to one side of the hook is provided to limit the eccentric rotation.

또한, 주권후크(6)가 과다하게 권하할 경우 웨이트롤(29)이 터치구동롤(31)에 걸쳐지면서 수직으로 젖혀지게 되는데, 이때 웨이트롤과 주권후크가 충돌될 수 있다.In addition, when the sovereign hook 6 is excessively recommended, the wait trolley 29 is vertically rolled over the touch driving roll 31, and the wait trolley and the sovereign hook may collide with each other.

The impact is alleviated by the elastic force compressed therebetween.

이하, 본 발명의 작용을 설명한다.The operation of the present invention will be described below.

이송대차(10)에 실려서 원료장입바스켓(1)이 권상위치에 도착하게 되면 주권후크(6)가 하강하게 되고, 터치구동롤(31)에 웨이트롤(29)이 받히면서 계속해서 주권후크가 하강하게 되면 잠금대(20)가 결합핀(27)을 중심으로 회전되면서 주권후크의 입구를 개방하게 된다.When the raw material loading basket 1 reaches the hoisting position by being loaded on the transport cart 10, the sovereignty hook 6 is lowered, and the sovereign hook is continuously supported by the waitroll 29 on the touch driving roll 31. When lowered, the lock 20 is rotated about the coupling pin 27 to open the inlet of the sovereign hook.

이때, 그 입구가 개방된 주권후크(6)에 주권걸이(5-1)를 줄걸이한 후, 다시 주권후크를 권상시키게 되면 웨이트롤(29)의 무게중심에 의해 잠금대(20)가 결합핀(27)을 중심으로 회전되고, 이어서 잠금대는 스토퍼(28)에 의해 회전이 제동되면서 주권후크의 입구를 가로질러 잠그게 된다.At this time, after the sovereignty hook (5-1) to the sovereign hook (6) that the opening is opened, when the sovereign hook is hoisted again, the lock 20 is coupled by the center of gravity of the wait trolley 29 The pin 27 is rotated about the pin 27, and then the lock is locked across the inlet of the sovereign hook while the rotation is braked by the stopper 28.

따라서, 잠금대(20)에 의해 잠금상태가 되는 주권후크(6)는 원료장입바스켓(1)의 원료스템핑작업시에도 주권걸이(5-1)로부터 이탈되는 현상이 발생되지 않게 된다.Therefore, the phenomenon that the sovereign hook 6, which is locked by the locking table 20, does not occur from the sovereign hanger 5-1 even during the raw material stamping operation of the raw material loading basket 1 does not occur.

그리고, 주권걸이(5-1)로부터 주권후크(6)의 취외작업은 상기의 줄걸이작업과 같이 수행하게 된다.Then, the take-out operation of the sovereignty hook 6 from the sovereignty hanger 5-1 is performed as the above-described hanger work.

본 발명은 주권후크에 줄걸이된 주권걸이를 자동 잠금으로써 원료장입바스켓에 의한 원료스템핑작업시 주권후크으로부터 주권걸이의 이탈을 방지하게 되고, 이로 부터 원료장입바스켓과 전기로설비의 충돌과 같은 대형설비사고를 예방할 수 있는 효과를 제공하게 된다.The present invention prevents the detachment of the sovereignty hanger from the sovereignty hook during the raw material stamping operation by the raw material loading basket by automatic locking of the sovereign hanger hooked to the sovereignty hook, from which the large size such as the collision of the raw material loading basket and the electric equipment It will provide the effect to prevent equipment accidents.
