Description

언로더 슈트 방호장치{CHUTE PROTECTION DEVICE OF UNLOADER}Unloader suit protection device {CHUTE PROTECTION DEVICE OF UNLOADER}

본 발명은 연속식 언로더 하부 슈트커버의 자동 개폐에 관한 것으로, 더욱상세히는 다수의 하부 벨트 컨베이어 슈트중 선택 되어진 커버를 개방하고 이외의 것은 개폐할수 있도록 한 언로더 슈트 방호장치에 관한 것이다.The present invention relates to automatic opening and closing of the continuous unloader lower chute cover, and more particularly, to an unloader chute protection device that opens and closes a selected cover among a plurality of lower belt conveyor chutes.

일반적으로 제철소에서는 연.원료의 수송은 육상과 해상을 통하여 이루어 지며 이중 대다수는 선박을 이용 해송으로 이루어 진다.선박으로 수송된 연.원료는 하역기(언로더,연속식언로더)를 통하여 하역된다.Generally, in steel mills, the transportation of fuel and raw materials is carried out by land and sea, most of which are carried by ships. The raw materials transported by ships are unloaded through unloaders (unloaders, continuous unloaders).

연속식 언로더의 로터리 벨트 컨베이어 슈트는 지상의 여러개의 하부 벨트컨베이어에 선택적으로 수송물을 보내게 되고 선택 되지 않은 여러개의 하부 슈트는 커버는 개폐하여 작업자의 점검이나 점검시 안전 사고를 방지한다.The rotary belt conveyor chute of the continuous unloader selectively transports the cargo to several lower belt conveyors on the ground, and the unselected lower chute chutes open and close the cover to prevent safety accidents during the operator's inspection or inspection.

하부 슈트커버는 중량물이어서 작업자 1인이 이동할수 없으며 특히 슈트 내부는 깊고 벨트 컨베이어가 회전하기 때문에 상시 위험한 개소인데 로터리 벨트 컨베이어 슈트가 하부 슈트상부의 넓은 범위로 선회되기때문에 특별한 안전가대를 설치 할수 없고 작업 특성상 연,원료의 종류에따라 로터리 벨트 컨베이어 슈트를 여러개의 하부슈트에 수시로 선택해야 하기 때문에 작업시간이 많이 소요된다.The lower chute cover is heavy and cannot be moved by one worker. Especially, the inside of the chute is deep and the belt conveyor rotates. This is always a dangerous place. As the rotary belt conveyor chute is swiveled over a wide range of the upper chute, no special safety stand can be installed. Due to the nature of the work, the rotary belt conveyor chute must be selected from several lower chutes depending on the type of lead and raw materials.

본 발명은 상기와 같은 문제점을 해결하기 위한 것으로, 연속식 언로더의 다수개의 하부 슈트 상부에서 로터리 벨트 컨베이어 슈트가 이동시 컨베이어 하단부 커버 자동 개폐 장치에 의하여 작업하는 슈트의 커버를 개방함으로서 작업 휴지시간을 없애고 작업자의 안전사고를 방지할 수 있도록 한 언로더 슈트 방호장치를 제공함에 그 목적이 있다.The present invention is to solve the above problems, the operation of the downtime by opening the cover of the chute working by the automatic opening and closing of the conveyor bottom cover when the rotary belt conveyor chute at the upper part of the lower chute of the continuous unloader It is an object of the present invention to provide an unloader chute protection device that can be eliminated and prevents a worker's safety accident.

본 발명의 상기한 목적은 선박으로부터 수송물을 하역하여 로터리 벨트컨베이어를 통해 하부벨트컨베이어로 수송물을 전달할 때 작업조건에 따라 슈트를 이동시킬 경우 커버를 자동으로 개폐하여 보호하는 언로더 슈트 방호장치에 있어서, 상기 커버의 외단양측에 핀으로 고정된 링크와; 상기 커버의 하단에 고정되고 레일 상에 거치되는 휠과; 상기 커버의 내단양측에 연결된 와이어와; 상기 와이어에 고정된 웨이트와; 상기 슈트의 하단에 구비되고 상기 링크를 접촉가압 가능하게 설치된 스토퍼를 포함하여 구성함에 의해 달성된다.The above object of the present invention is an unloader chute protection device to automatically open and protect the cover when moving the chute according to the working conditions when unloading the cargo from the ship to transport the cargo to the lower belt conveyor through a rotary belt conveyor A pin fixed to the outer ends of the cover; A wheel fixed to a lower end of the cover and mounted on a rail; Wires connected to both inner ends of the cover; A weight fixed to the wire; It is achieved by including a stopper provided at the bottom of the chute and the link is installed to be contact pressure.

하부슈트 커버(10)는 2개가 한쌍을 이루며 좌측 커버의 외측단부에 핀(15)이 삽입된 링크(12) 2개가 부착되어 우측 커버의 외측단부에 핀(15)이 삽입된 2개의 링크(15)가 삽입된다.The lower chute cover 10 has two pairs, and two links 12 having a pin 15 inserted into the outer end of the left cover are attached to the two links having the pin 15 inserted into the outer end of the right cover. 15) is inserted.

이때 링크(12)는 일측 선단부는 커버(10) 외측에 일측 선단부는 링크(12)와 링크(12)가 핀으로 연결 되며 커버(10) 전후에 각 각 1개씩 위치한다.At this time, one end of the link 12 is connected to the front end of the cover 10 and one end of the link 12 is connected to the link 12 and the link 12 by pins, and each one is located before and after the cover 10.

커버(10) 하부에는 좌우 움직임을 원활히 할수 있는 휠(14)이 각각 4개씩 부착되며 휠(14) 하부에는 레일(11)이 위치하게 된다.Four wheels 14 each capable of smoothly moving left and right are attached to the lower portion of the cover 10, and the rails 11 are positioned below the wheels 14.

커버(10)와 커버(10)가 접촉되는 내측에는 각각 와이어(17)가 고정되며 와이어(17) 하부는 웨이트(13)가 고정된다.The wire 17 is fixed to the inner side where the cover 10 and the cover 10 contact, and the weight 13 is fixed to the lower part of the wire 17.

커버(10)가 접촉된 위치에서 와이어(17)가 웨이트(13) 무게에 의하여 하부로 처지는 위치에 쉬이브(16)가 측으로 2개가 설치 된다.In the position where the cover 10 is in contact with the wire 17, two pieces of the sheave 16 are installed on the side at the position sagging downward by the weight of the weight 13.

와이어(17)와 웨이트(13)는 커버(10) 전.후에 각각 설치된다.The wire 17 and the weight 13 are respectively installed before and after the cover 10.

한편 웨이트의 무게는 로타리 벨트 컨베이어(19)의 슈트(22) 스토퍼(18)가 이탈한 후 커버(10)가 개폐 될수 있는 무게를 가져야 한다.Meanwhile, the weight of the weight should have a weight that the cover 10 can be opened and closed after the chute 22 stopper 18 of the rotary belt conveyor 19 is separated.

따라서, 상기와 같은 본 발명은 선박으로 부터 하역된 원료가 로터리 벨트컨베이어통하여 하부 벨트 컨베이어(20)에 이송될때 작업 조건에 따라 로터리 벨트컨베이어를 작업 조건에 맞는 하부 슈트를 선택 하게 된다.Therefore, the present invention as described above selects the lower chute for the rotary belt conveyor according to the working conditions when the raw material unloaded from the vessel is transferred to the lower belt conveyor 20 via the rotary belt conveyor.

이때 슈트(22)의 이동으로 하부에 고정된 스토퍼(18)가 도 3에 도시된 것처럼 슈트(a)가 슈트(a')로 변환될때 링크(12)를 밀게되는 형상이 되어 링크(12)가 하부로 눌러 지게 된다.At this time, the stopper 18 fixed to the lower portion by the movement of the chute 22 is shaped to push the link 12 when the chute a is converted to the chute a ', as shown in FIG. Is pressed down.

이에 따라 커버(10)가 양측으로 밀려 나면서 하부슈트가 개방되게 되고 커버(10)에 연결된 와이어(17)가 웨이트(13)를 상승 시키게 된다.Accordingly, as the cover 10 is pushed to both sides, the lower chute is opened, and the wire 17 connected to the cover 10 raises the weight 13.

한편 작업 조건에 따라 로터리 벨트 컨베이어를 또 다른 하부 벨트 컨베이어(20)로 선택 할때 도 4에 도시된 것처럼 슈트(22)가 이동할때 하부에 고정된 스토퍼(18)가 링크를 이탈하게 되면서 웨이트(13)는 무게에 의하여 하부로 낙하 되고 연결된 와이어(17)를 당기게 되고 와이어(17)에 연결된 커버(10)가 중앙으로 이동하면서 하부 슈트가 개폐되게 된다.Meanwhile, when the rotary belt conveyor is selected as another lower belt conveyor 20 according to the working condition, as the chute 22 moves as shown in FIG. 4, the stopper 18 fixed to the lower part breaks off the link. 13 is dropped to the bottom by the weight and pull the connected wire 17 and the lower chute is opened and closed as the cover 10 connected to the wire 17 moves to the center.

즉, 상기와 같은 작용(도 4에서 a'- a - a" 변환)을 슈트변경에 따라 반복하게 된다.That is, the above operation (a'-a-a "conversion in FIG. 4) is repeated according to the chute change.

이와같은 본 발명은 작업조건에 따라 개페되어 있는 하부 슈트를 로터리 벨트 컨베이어 슈트의 이동으로 작업 조건에 맞는 하부 슈트커버를 개방하고 작업 하지 않는 하부슈트 커버를 개폐함으로서 안전 구조물을 설치할수 없는 슈트 개구부에 자동으로 개페할수있는 장치를 제공함에 따라 항상 위험한 개소가 폐쇄되어 있어 안전 사고를 방지하는 효과가 있다.In the present invention, the lower chute opened according to the working conditions is opened in the chute opening where safety structures cannot be installed by opening the lower chute cover suitable for the working conditions and opening and closing the lower chute cover not working by moving the rotary belt conveyor chute. By providing a device that can be opened automatically, dangerous places are always closed, thus preventing a safety accident.
