상기한 목적을 달성하기 위하여 본 고안은 횡행그래브의 전면 좌우측에 부착되면서 거더의 상면 좌우측편에 고정된 횡행브래킷에 의해 각각 터치되는 리밋스위치와; 상기 리밋스위치의 감지신호에 의해 작동되면서 지지대로 접근하는 횡행슬라브를 감지하도록 상기 거더의 하부 좌우측에 설치되는 레이저센서와; 상기 리밋스위치의 감지신호를 전송받아 상기 레이저센서를 작동시키고, 상기 레이저센서의 감지신호를 수신하여 경고부저와 경광등을 작동시키는 동시에 통크레인의 전원을 차단하는 제어기로 구성되는 것을 특징으로 하는 통크레인의 슬라브횡행 제어장치를 제공한다.In order to achieve the above object, the present invention is attached to the front left and right sides of the transverse grab and the limit switch is respectively touched by a transverse bracket fixed to the left and right side of the upper surface of the girder; A laser sensor installed on the lower left and right sides of the girder to detect a transverse slab approaching the support while being operated by the detection signal of the limit switch; Receiving the detection signal of the limit switch to operate the laser sensor, receiving the detection signal of the laser sensor to operate a warning buzzer and a warning light, characterized in that it consists of a controller to cut off the power of the barrel crane It provides a slab traverse control device.
도면을 참조하여 본 고안을 설명한다.The present invention will be described with reference to the drawings.
도2는 본 고안에 따른 슬라브횡행 제어장치가 장착된 통크레인을 나타내는 사시도이다.Figure 2 is a perspective view showing a barrel crane equipped with a slab transverse control apparatus according to the present invention.
본 고안에서는 레이저센서(6-1,6-2)가 각각 지지대(13)의 바로 안쪽에 위치하도록 거더(Girder)(2)의 하부측에 고정 부착되어 있어 그래브(Grab)(10)에 의해 횡행되는 슬라브(5)를 지지대(13)와 충돌되기 전에 감지하게 된다.In the present invention, the laser sensors 6-1 and 6-2 are fixedly attached to the lower side of the girder 2 so that the laser sensors 6-1 and 6-2 are located just inside the support 13, respectively. The slab 5 traversed by it is detected before colliding with the support 13.
이때, 그래브(Grab)(10)의 전면 좌우측편에 각각 리밋스위치(4-1,4-2)가 부착되어 있고, 횡행브래킷(8-1,8-2))은 그래브(10)를 따라 좌우로 횡행되는 리밋스위치(4-1,4-2)와 각각 터치되도록 거더(2)의 상면 좌우측편에 고정 설치되어 있다.At this time, the limit switches 4-1 and 4-2 are attached to the front left and right sides of the grab 10, and the transverse brackets 8-1 and 8-2 are respectively attached to the grab 10. It is fixedly installed on the left and right sides of the upper surface of the girder 2 so as to touch the limit switches 4-1 and 4-2, which are laterally traversed along each other.
여기서, 장척의 슬라브(5) 양단이 지지대(13)에 충돌되기 전에 횡행브래킷(8-1,8-2)이 리밋스위치(4-1,4-2)에 감지되어 하므로 이러한 점을 고려하여 횡행브래킷(8-1,8-2)을 거더(2)의 상면 좌우측편에 설치하여야 한다.Here, the transverse brackets 8-1 and 8-2 are sensed by the limit switches 4-1 and 4-2 before both ends of the long slab 5 collide with the support 13, Transverse brackets (8-1, 8-2) are to be provided on the left and right sides of the upper surface of the girders (2).
그리고, 레이저센서(6-1,6-2)는 횡행브래킷(8-1,8-2)이 리밋스위치(4-1,4-2)에 감지된 후 작동되도록 설치되어 있다.The laser sensors 6-1 and 6-2 are installed to operate after the transverse brackets 8-1 and 8-2 are sensed by the limit switches 4-1 and 4-2.
한편, 제어기(7)는 횡행브래킷(8-1,8-2)이 리밋스위치(4-1,4-2)에 감지되면 그 감지신호를 전송받아 레이저센서(6-1,6-2)를 작동시키게 된다.On the other hand, when the transverse brackets 8-1 and 8-2 are detected by the limit switches 4-1 and 4-2, the controller 7 receives the detection signals and receives the laser sensors 6-1 and 6-2. Will be activated.
그리고, 레이저센서(6-1,6-2)에 슬라브(5)가 감지되면 다시 제어기(7)에서 그 감지신호를 전송받아 횡행슬라브가 더 이상 진행되지 않도록 통크레인의 전원을 차단하게 된다.Then, when the slab 5 is detected by the laser sensors 6-1 and 6-2, the controller 7 receives the detection signal again to cut off the power supply of the crane crane so that the transverse slab does not proceed any further.
또한, 제어기(7)에서는 경고부저(1)를 울리는 동시에 경광등(9)을 점등하게 되고, 운전실의 운전자는 경고부저(1)의 경고음과 경광등(9)의 불빛에 의해 그래브(10)를 중앙측으로 진행시키게 된다.In addition, the controller 7 sounds the warning buzzer 1 and lights the beacon 9 at the same time. The driver of the cab turns the grab 10 on by the warning sound of the warning buzzer 1 and the light of the beacon 9. Proceed to the center side.
본 고안은 연주공정에서 생산된 슬라브를 수입 및 열연공정으로의 장입을 위한 권상작업 후, 횡행을 제어함으로써 슬라브의 횡행오버런(Overrun)에 의한 충돌사고를 방지할 수 있는 효과를 제공하게 된다.The present invention provides an effect that can prevent the accident caused by the overrun of the slab by controlling the traverse after lifting the slab produced in the playing process into the import and hot rolling process.
