이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 상세하게 설명한다. 도면들 중 동일한 구성요소들은 가능한 어느 곳에서든지 동일한 부호로 표시한다. 또한 본 발명의 요지를 불필요하게 흐릴 수 있는 공지 기능 및 구성에 대한 상세한 설명은 생략한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Like elements in the figures are denoted by the same reference numerals wherever possible. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

도 1 및 도 2는 본 발명의 전기로의 로상재 투입장치를 나타내고 로상재를 투입하는 모습을 나타낸 도면들로서, 본 발명의 로상재 투입장치는 호퍼(110), 개폐구(120) 및 작동수단(130)을 포함할 수 있다.1 and 2 are diagrams showing the furnace material input device of the electric furnace of the present invention and the state of the furnace material input, the furnace material input device of the present invention is a hopper 110, the opening and closing port 120 and the operating means 130 ) May be included.

호퍼(110)는 상부 투입구(111)를 통해 내부에 로상재를 저장하며, 하부 배출구(113)를 통해 저장한 로상재를 전기로 내부에 투입한다. 호퍼(110)는 중간으로부터 배출구(113)를 향해 예컨대, 일면이 테이퍼지게 형성되어 로상재의 투입을 원활히 한다.The hopper 110 stores the furnace material in the interior through the upper inlet 111 and injects the furnace material stored through the lower outlet 113 into the electric furnace. The hopper 110 is tapered, for example, on one surface toward the discharge port 113 from the middle to facilitate the introduction of the furnace material.

이러한 호퍼(110)는 크레인의 와이어(3)에 연결됨으로써 매달려 크레인이 이동하는 방향에 따라 이동하며 로상재를 전기로 내부에 투입한다. 호퍼(110)는 상부 좌우에 행거(115)를 설치하여 와이어(3)와 연결되며, 하부에 고리를 형성하여 와이어(3)와 더 연결됨으로써 크게 흔들거리지 않고 수직을 이룬다. 이때, 행거(115)는 경사지게 설치되어 와이어(3)가 호퍼(110)를 안정적으로 현수하도록 한다.The hopper 110 is connected to the wire (3) of the crane is moved in accordance with the direction in which the hanging crane moves and put the furnace floor material into the electric furnace. The hopper 110 is connected to the wire 3 by installing the hangers 115 on the upper left and right, and forms a ring at the bottom to be further connected to the wire 3 to form a vertical without large shaking. At this time, the hanger 115 is installed to be inclined so that the wire 3 is suspended in the hopper 110 stably.

게다가, 호퍼(110)는 상부 일면에 상하로 길이를 갖는 장공 형태의 관측창(117)을 투시가능하게 형성하여 내부에 장입된 로상재의 잔존 정도를 파악할 수 있도록 한다.In addition, the hopper 110 is formed to be able to see through the observation window 117 of the long hole shape having a length up and down on the upper surface to determine the remaining degree of the furnace material charged therein.

개폐구(120)는 호퍼(110)의 배출구(113)에 설치되어 배출구(113)를 개폐하며, 작동수단(130)은 개폐구(120)와 인접하게 호퍼(110)에 설치되어 개폐구(120)를 작동시킨다.The opening and closing port 120 is installed in the outlet 113 of the hopper 110 to open and close the outlet 113, the operation means 130 is installed in the hopper 110 adjacent to the opening and closing 120 to open and close the opening 120 It works.

개폐구(120)는 판상형을 이루어 평상시 배출구(113)를 막고 있으며, 좌우로 슬라이드하게 이동하며 배출구(113)를 개방한다. 호퍼(110)는 배출구(113) 좌우에 지지레일을 마련하여 개폐구(120)의 좌우 이동을 가이드할 수 있고, 이와 달리 개폐구(120)가 배출구(113)를 가로질러 관통함으로써 좌우로 이동하며 개폐할 수 있다.The opening and closing hole 120 is formed in a plate shape to block the usual discharge port 113, and slides to the left and right to open the discharge port 113. The hopper 110 may guide the left and right movement of the opening and closing hole 120 by providing a support rail on the left and right of the discharge port 113. Alternatively, the opening and closing hole 120 penetrates through the discharge hole 113 to move left and right. can do.

작동수단(130)은 유압 또는 공압실린더로 이루어져, 개폐구(120)와 동일 수평선상에 놓이게 연결됨으로써 로드가 신축됨에 따라 개폐구(120)가 좌우로 이동하며 호퍼(110)의 배출구(113)를 개폐할 수 있도록 할 수 있다.Actuating means 130 is composed of a hydraulic or pneumatic cylinder, the opening and closing 120 is moved to the left and right as the rod is stretched by being placed on the same horizontal line with the opening and closing 120, opening and closing the outlet 113 of the hopper 110 You can do it.

도 3에 도시된 바와 같이, 이와 달리 작동수단(130)은 모터(131)와 기어열(133)로 이루어져 개폐구(120)가 호퍼(110)의 배출구(113)를 개폐할 수 있도록 작동시킬 수 있다.As shown in FIG. 3, the operating means 130 may alternatively include a motor 131 and a gear train 133 so that the opening and closing hole 120 may open and close the outlet 113 of the hopper 110. have.

기어열(133)은 랙(133a)과 피니언(133b)으로 이루어질 수 있고, 이때 랙(133a)은 모터(131)의 로드에 장착되고, 피니언(133b)은 개폐구(120)의 일측면 일부에 형성된다.The gear train 133 may be formed of a rack 133a and a pinion 133b, in which the rack 133a is mounted to a rod of the motor 131, and the pinion 133b is disposed on a part of one side of the opening and closing hole 120. Is formed.

따라서, 모터(131)가 정·역회전함에 따라 랙(133a)과 피니언(133b)이 전후 방향으로 이동하며 치합되고, 이에 의해 개폐구(120)가 좌우로 이동함으로써 호퍼(110)의 배출구(113)가 개폐된다.Accordingly, as the motor 131 rotates forward and backward, the rack 133a and the pinion 133b move and engage in the front-back direction, whereby the opening / closing port 120 moves left and right, thereby discharging the opening 113 of the hopper 110. ) Is opened and closed.

호퍼(110)는 일면에 브라켓이나 하우징을 설치하여 모터(131)가 호퍼(110)에 견고히 장착될 수 있도록 한다.The hopper 110 installs a bracket or a housing on one surface so that the motor 131 can be firmly mounted to the hopper 110.

이와 같은 작동수단(130)은 유선 또는 무선 통신에 의해 그 작동이 제어됨으로써 크레인 운전자가 호퍼(110)를 이동시키며 개폐구(120)를 직접 개폐할 수 있도록 한다.Such operation means 130 is controlled by wire or wireless communication so that the crane driver to move the hopper 110 and directly open and close the opening 120.

예컨대, 작동수단(130)을 이루는 실린더에 유압 또는 공압을 부여하는 펌프 등 또는 모터(131)에 유선 통신케이블을 연결하고, 그 유선 통신케이블에 온/오프 버튼스위치나 토글스위치 등을 장착한 컨트롤러를 연결하여, 크레인 운전자가 컨트롤러의 스위치를 조작하여 펌프 등 또는 모터(131)를 구동시킴으로써 개폐구(120)를 작동시켜, 크레인 운전자가 호퍼(110)를 이동시키며 직접 개폐구(120)를 개폐할 수 있도록 할 수 있다.For example, a controller in which a wired communication cable is connected to a pump or a motor 131 for supplying hydraulic pressure or pneumatic pressure to a cylinder constituting the operating means 130, and a controller equipped with an on / off button switch or a toggle switch on the wired communication cable. By connecting the crane driver by operating the switch of the controller to drive the pump or the motor 131 to operate the opening and closing 120, the crane driver can move the hopper 110 and directly open and close the opening 120. You can do that.

이와 달리, 작동수단(130)은 펌프 등 또는 모터(131)를 제어할 수 있는 무선 수신기, 마이콤 등을 탑재한 제어수단을 포함하고, 무선송신기, 제어버튼 등을 갖는 리모우트 컨트롤러를 마련하여, 크레인 운전자가 리모우트 컨트롤러의 제어버튼을 조작해 무선제어신호를 송신하면 작동수단(130)의 제어수단이 그 무선제어신호를 수신하고, 그 즉시 제어수단이 무선제어신호에 따라 펌프 등 또는 모터(131)를 구동시킴으로써 개폐구(120)를 작동시켜, 크레인 운전자가 호퍼(110)를 이동시키며 직접 개폐구(120)를 개폐할 수 있도록 할 수 있다.On the contrary, the operation means 130 includes a control means equipped with a wireless receiver, a microcomputer, or the like capable of controlling the pump or the motor 131, and provides a remote controller having a wireless transmitter, a control button, and the like, When the crane driver operates the control button of the remote controller and transmits the radio control signal, the control means of the operation means 130 receives the radio control signal, and immediately the control means transmits the pump or the motor according to the radio control signal ( By operating the opening and closing 120 by driving the 131, the crane driver can move the hopper 110 to directly open and close the opening and closing 120.

이 때문에, 보수작업지연 등의 일이 발생하지 않아 작업시간이 단축되고, 작업자가 전기로에 직접 들어가 로상재를 투입하는 일이 없어 고열작업으로 인한 안전사고가 예방된다.For this reason, the work time is shortened because no maintenance work is delayed, and the worker does not directly enter the electric furnace to inject the furnace material, thereby preventing safety accidents due to high temperature work.

한편, 호퍼(110)는 배출구(113)에 투입 가이드구(119)를 경사지게 설치하여 적소에 로상재를 투입할 수 있도록 한다.
On the other hand, the hopper 110 is installed to the inlet guide port 119 to the outlet 113 inclined so that the furnace material can be put in place.

상술한 바와 같이 본 발명에 의하면, 전기로의 로상재를 자동 투입함으로써 보수작업지연 등의 일이 발생하지 않아 작업시간을 단축할 수 있고, 고열작업으로 인한 안전사고를 예방할 수 있다.
As described above, according to the present invention, by automatically inserting the furnace material into the electric furnace, work delay or the like does not occur, thereby reducing work time and preventing safety accidents due to high heat work.
