리클레이머의 임팩트롤러용 롤러스탠드{Roller stand for the impact roller in the reclaimer}Roller stand for the impact roller in the reclaimer}

본 발명은 야드에 파일형태로 적치되어 있는 광석 또는 원료를 불출하는 리클레이머에 장착된 임팩트롤러용 롤러스탠드에 관한 것이고, 더 상세하게는 리클레이머의 붐벨트 및 배출슈트를 통해 지상벨트 컨베이어로 낙하하는 광석 또는 원료에 의해서 파손된 임팩트롤러를 용이하게 교환할 수 있는 리클레이머의 임팩트롤러용 롤러스탠드에 관한 것이다.The present invention relates to a roller stand for an impact controller mounted on a reclaimer for discharging ores or raw materials stacked in the form of a yard in a yard, and more specifically, a ground belt conveyor through a boom belt and a discharge chute of the reclaimer. The present invention relates to a roller stand for an impact controller of a reclaimer which can easily replace an impact controller damaged by an ore or raw material falling into the furnace.

일반적으로, 선박(미도시)에서 하역된 제철산업용 광석 또는 원료는 야드에 파일형태로 적치된다. 그리고, 야드에 적치되어 있는 광석 또는 원료는 리클레이머에 의해서 야드로부터 불출되어 지상벨트 컨베이어를 따라서 사용개소로 이송된다.Generally, iron ore or raw materials for the steel industry unloaded from a vessel (not shown) are piled in a yard. The ore or raw materials stored in the yard are discharged from the yard by the reclaimer and transferred to the use place along the ground belt conveyor.

즉, 도 1 내지 도 3을 참조하면, 리클레이머(10)는 지상레일을 따라서 야드구간을 이동하면서 야드에 적재되어 있는 광석 또는 원료(90)를 불출한다. 리클레이머(10)의 불출작업에 의하여 불출되는 광석 또는 원료(90)는 붐벨트(12)와 배출슈트(50)를 통해서 지상벨트 컨베이어(20)로 낙하한다. 지상벨트 컨베이어(20)는 캐리어롤러 스탠드(30)에 회전가능하게 지지되어 있는 캐리어롤러의 구동에 의해서이동한다.That is, referring to FIGS. 1 to 3, the reclaimer 10 discharges the ore or raw material 90 loaded on the yard while moving the yard section along the ground rail. The ore or raw material 90 discharged by the discharging operation of the reclaimer 10 falls to the ground belt conveyor 20 through the boom belt 12 and the discharge chute 50. The ground belt conveyor 20 is moved by the driving of the carrier roller which is rotatably supported by the carrier roller stand 30.

배출슈트(50)를 통해서 낙하하는 광석 또는 원료(90)에 의해서 지상벨트 컨베이어(20)에 인가되는 낙하충격을 완화시키기 위하여 배출슈트(50)의 배출단 하부에는 지상벨트 컨베이어(20)를 지지하는 임팩트롤러(80)가 제공된다. 그리고, 임팩트롤러(80)는 소정형상의 롤러케이싱(60)에 회전가능하게 장착된다. 또한, 롤러케이싱(60)은 케이싱 지지프레임(70)에 고정볼트(60-1)에 의해서 고정된다. 케이싱 지지프레임(70)은 연결프레임(95)을 통해서 배출슈트(50)에 고정된다.The ground belt conveyor 20 is supported under the discharge end of the discharge chute 50 to mitigate the drop impact applied to the ground belt conveyor 20 by the ore or raw material 90 falling through the discharge chute 50. An impact controller 80 is provided. The impact controller 80 is rotatably mounted to a roller casing 60 of a predetermined shape. In addition, the roller casing 60 is fixed to the casing support frame 70 by a fixing bolt 60-1. The casing support frame 70 is fixed to the discharge chute 50 through the connecting frame 95.

상술된 바와 같이, 리클레이머(10)의 불출작업에 의해서 불출되는 광석 또는 원료(90)가 배출슈트(50)를 통해서 임팩트롤러(80) 상의 지상벨트 컨베이어(20)로 낙하할 때 롤러케이싱(60) 내부의 틈사이와 임팩트롤러 샤프트(80-1)에 이물질이 끼여서 임팩트롤러(80)가 원활하게 회전하지 못하여 조기에 파손된다.As described above, the roller casing when the ore or raw material 90 discharged by the discharging operation of the reclaimer 10 falls through the discharge chute 50 to the ground belt conveyor 20 on the impact controller 80. (60) Foreign matter is caught between the gaps inside and the impact controller shaft 80-1, so that the impact controller 80 does not rotate smoothly and is damaged early.

이와 같이 파손된 임팩트롤러(80)를 교환하기 위한 교환작업은 도 4a 내지 도 4d에 도시된 바와 같다. 먼저, 연결프레임(95)을 분리하여 배출슈트(50)로부터 케이싱 지지프레임(70)을 분리한다. 고정볼트(60-1)를 체결해제시킨 후 햄머 등을 이용해서 롤러케이싱(60)을 화살표(A; 도 4b 참조) 방향으로 타격한 후 화살표(B; 도 4c 참조) 방향으로 배출하여 롤러케이싱(60)을 케이싱 지지프레임(70)으로부터 분리시킨다. 이와 같이 분리된 롤러케이싱(60)을 지상벨트 컨베이어(20)로부터 취외시킨 후 손상된 임팩트롤러를 화살표(C; 도 4d 참조) 방향으로 들어올려서 롤러케이싱(60)으로부터 분리한 후 신규의 임팩트롤러를 롤러케이싱(60)에 설치한다.The replacement operation for replacing the damaged impact controller 80 is as shown in Figures 4a to 4d. First, the connection frame 95 is separated to separate the casing support frame 70 from the discharge chute 50. After disengagement of the fixing bolt 60-1, the roller casing 60 is hit in the direction of arrow A (see FIG. 4B) using a hammer or the like and then discharged in the direction of arrow B (see FIG. 4C). Separate the 60 from the casing support frame 70. After removing the roller casing 60 thus separated from the ground belt conveyor 20, the damaged impact controller is removed from the roller casing 60 by lifting the damaged impact controller in the direction of an arrow (see FIG. 4D) and then a new impact controller. It is installed in the roller casing (60).

이 후에, 역순방향으로 롤러케이싱(60)을 케이싱 지지프레임(70)에 고정시키고 또한 연결프레임(95)을 사용하여 지지프레임(70)을 배출슈트(50)에 고정시킨다.Thereafter, the roller casing 60 is fixed to the casing support frame 70 in the reverse direction, and the support frame 70 is fixed to the discharge chute 50 using the connecting frame 95.

그러나, 이와 같은 임팩트롤러 교환작업은 협소한 공간에서 이루어지므로 번거롭고 또한 작업시간 및 인원이 많이 요구되며, 협소한 장소에서 롤러케이싱으로부터 임팩트롤러를 인출하므로 안전사고의 요인이 항상 존재한다.However, such an impact controller replacement work is cumbersome and requires a lot of work time and personnel since it is performed in a narrow space, and there is always a factor of a safety accident since the impact controller is withdrawn from the roller casing in a narrow place.

본 발명은 상기된 바와 같은 종래의 문제점을 해결하기 위하여 안출된 것으로, 리클레이머에 의해서 불출되는 광석 또는 원료가 배출슈트를 통해서 지상벨트 컨베이어로 낙하할 때 상기 배출슈트의 하부에서 지상벨트 컨베이어를 지지하는 임팩트롤러가 이물질 등에 의해서 파손되는 경우에 파손된 임팩트롤러를 용이하게 교환할 수 있는 임팩트롤러용 롤러스탠드를 제공하는 데 그 목적이 있다.The present invention has been made to solve the conventional problems as described above, when the ore or raw material discharged by the reclaimer falls to the ground belt conveyor through the discharge chute to the ground belt conveyor at the bottom of the discharge chute It is an object of the present invention to provide a roller stand for an impact controller that can easily replace a damaged impact controller when the supporting impact controller is broken by a foreign material or the like.
