본 발명은 하역기의 분진 방지용 급수제어장치, 보다 상세하게는 광석이나 석탄 등의 원료를 이송한 후 하역장비를 이용하여 호퍼에 하역할 때 분진의 비산을 방지하기 위해 호퍼에 살수하는 물을 하역장비의 저수조에 급수함에 있어서 그 급수를 제어하는 센서의 고장으로 인하여 발생되는 미급수 또는 과급수로 인한 넘침을 간단하게 방지하여 하역작업의 효율을 향상시킴과 아울러 물의 넘침으로 인한 환경 오염을 방지할 수 있게한 하역기의 분진 방지용 급수제어장치에 관한 것이다.The present invention is a water supply control device for dust prevention of the unloading machine, more specifically, the raw material for transporting ore or coal, and then unloading equipment to spray water to the hopper to prevent dust scattering when unloading to the hopper using the unloading equipment It is possible to improve the efficiency of unloading operation by preventing the overflow caused by the unsupply or supercharged water caused by the failure of the sensor that controls the water supply in the water tank of the water tank, and to prevent the environmental pollution caused by the overflow of the water. It relates to a water supply control device for dust prevention of the unloading machine.

일반적으로, 하역장비에 구비된 저수조에 물을 급수하기 위하여 호스릴로부터 호스를 풀어 내려 급수전에 연결한 후 급수전 밸브를 열게되면 공급되는 물이 고수위로 차오르면서 수위센서에 의해 솔레노이드밸브가 잠겨지게 됨으로써 급수가 중단되고, 살수 작업으로 저장조의 물이 저수위에 도달될 때 까지 소모되면 저수위센서에 의해 솔레노이드 밸브가 열려지면서 급수가 시작되어 항상 필요량을 유지토록하는 작용을 반복하게 되어 저수조 급수가 이루어지게 된다.In general, when water is supplied to the water tank provided in the unloading equipment, the hose is released from the hose reel, connected to the water supply, and the water supply valve is opened so that the solenoid valve is locked by the water level sensor while the water supplied to the high water level is opened. When the water supply is stopped and water is consumed until the water reaches the low level by the water spraying operation, the solenoid valve is opened by the low water level sensor, and the water supply starts and the water supply is repeated to maintain the required amount at all times. do.

그러나 상기와 같이 급수개시와 급수종료를 제어하기 위한 수위센서와 그 신호에 의해 동작되는 솔렌노이드 밸브에 분진이나 이물질이 누적될 경우 잦은 고장과 오동작이 발생됨으로써, 물의 급수가 중단되면서 살수 작업이 불가능하거나, 저수조에 급수되는 물이 설정범위를 초과하여 급수되는 과정에서 물이 저수조를 넘쳐흘러 오탁수가 바다로 유입되어 하역 작업중 환경오염의 주요 원인이 되고 있다.However, when dust or foreign matter accumulates in the solenoid valve operated by the water level sensor and the signal for controlling the water supply start and the water supply end as described above, frequent failures and malfunctions occur, so that the water supply is stopped and watering is impossible. In addition, when the water supplied to the reservoir exceeds the set range, the water overflows the reservoir, and the polluted water flows into the sea, which is a major cause of environmental pollution during the unloading operation.

본 발명은 위와 같은 종래의 저수조의 급수제어장치의 문제점을 감안하여 안출한 것으로, 그 목적은 저수조에 물을 급수할 때 급수제어장치의 고장으로 인한급수중단을 방지할 수 있는 하역기의 분진 방지용 급수제어장치를 제공하는 것이다.The present invention has been made in view of the problems of the conventional water supply control device of the reservoir, the purpose of which is to prevent the water supply interruption due to the failure of the water supply control device when water is supplied to the reservoir water supply for dust prevention It is to provide a control device.

호스릴(11)을 통해 급수전(12)으로부터 공급받은 물을 분진이 발생되는 호퍼(13)에 살수하기 위해 하역장비에 물이 저장되는 저수조(10)가 설치되고, 이 저수조(10)의 내부에는 급수된 물의 부력에 의해 승강되는 플로우트(20)가 설치되어 있다.In order to spray the water supplied from the water supply 12 through the hose reel 11 to the hopper 13 in which dust is generated, a reservoir 10 for storing water in the unloading equipment is installed, and the interior of the reservoir 10 is provided. The float 20 which is lifted and lowered by the buoyancy of the water supplied is provided.

상기 플로우트(20)의 상부면에는 부력에 의한 위치변위를 수직으로 나타내는 작동봉(21)이 구비되어 있되 저수조(10)의 상측에 형성한 다수의 가이드롤(30)에 수직으로 승강되게 설치되고, 상기 작동봉(21)의 외측면에는 스프링(23)을 매개로 다른 기어와 맞물릴 때 완충력과 밀착력을 동시에 제공하는 래크형의 기어열(22)이 형성되어 있다.The upper surface of the float 20 is provided with an operating rod 21 for vertically indicating the positional displacement due to buoyancy, but is installed to be elevated vertically to the plurality of guide rolls 30 formed on the upper side of the reservoir (10) On the outer surface of the operating rod 21, a rack-type gear train 22 is formed to simultaneously provide a cushioning force and a close contact force when engaged with another gear via a spring 23.

상기 작동봉(21)에 형성된 기어열(22)이 통과하는 진행로에는 이 기어열의 직진운동을 회전운동으로 전환시켜 물의 공급을 제어하도록 피니언기어(41)에 의해 개폐되는 밸브(40)를 갖춘 급수관(42)이 설치되어 있다.The passageway through which the gear train 22 formed in the operating rod 21 passes is provided with a valve 40 which is opened and closed by the pinion gear 41 to control the supply of water by converting the linear motion of the gear train into a rotational motion. The water supply pipe 42 is provided.

이때 작동봉(21)에 형성되는 기어열(22)은 그 작동봉의 외측면 전구간에 일체로 형성하는 것도 가능하나, 플로우트(20)가 저수위에 도달되는 구간과 만수위에 도달되는 구간에만 부분적으로 형성하는 것도 바람직하다.At this time, the gear train 22 formed in the operating rod 21 may be integrally formed between the outer surface of the operating rod, but only partially formed in a section in which the float 20 reaches a low water level and reaches a full water level. It is also preferable to.

따라서, 상기와 같은 본 발명은 급수전(12)으로부터 급수관(42)을 통해 저수조(10)로 공급된 물이 차오르게 되면 이에 비례하여 저수조에 설치된 플로우트(20)가 떠오르게 되면서 그 상측에 수직으로 설치된 작동봉(21)을 동시에 상향으로 밀어 올리게 된다.Therefore, in the present invention as described above, when the water supplied from the water supply 12 to the water storage tank 10 through the water supply pipe 42 is filled, the float 20 installed in the water storage tank rises in proportion thereto, and is installed vertically on the upper side thereof. The operating rod 21 is pushed upward at the same time.

상기 동작에 의해 다수의 가이드롤(30)에 지지된 작동봉(21)이 직진동작을하면서 상승되어 만수위에 근접되게 도달되면, 작동봉(21)의 외측면에 형성된 래크형의 기어열(22)에 이맞물림된 피니언기어(41)가 잠금방향으로 회전되면서 그 밸브(40)를 잠그게 됨으로써 급수관(42)의 급수를 차단시키게 된다.When the operating rods 21 supported by the plurality of guide rolls 30 are raised while moving in a straight line to reach the full water level, the rack-type gear train 22 formed on the outer surface of the operating rods 21 by the above operation is reached. The pinion gear 41 meshed with) rotates in the locking direction to lock the valve 40 to block the water supply of the water supply pipe 42.

한편, 저수조에 저장된 물을 사용하여 그 수위가 떨어지면서 설정된 저수위에 도달될 경우 수위 및 자중의 영향에 의해 플로우트(20)와 그 작동봉(21)이 하강되면서 작동봉에 형성된 기어열(22)의 직진동작에 의해 이에 이맞물림된 피니언기어(41)를 열림방향으로 회전시켜 밸브(40)를 개방시켜 다시 급수관(420을 통해 급수를 개시하게 된다.On the other hand, when the water level is reached by using the water stored in the reservoir, and the set water level is reached, the float 20 and the operating rod 21 are lowered by the influence of the water level and the weight of the gear row 22 formed on the operating rod. By rotating the pinion gear 41 meshed by the straight operation of the in the opening direction to open the valve 40 to start the water supply through the water supply pipe 420 again.

즉, 저수조에 설정량의 물이 급수될 때 그 부력에 의해 급수가 차단되고, 저수조의 수위가 설정치 이하로 떨어질 때 부력과 플로우트의 자중에 의해 자동으로 급수를 재개하는 동작을 반복함으로써 급수를 제어하는 것이다.That is, the water supply is cut off by the buoyancy when the set water is supplied to the reservoir, and the water supply is controlled by repeating the operation of automatically resuming water by the buoyancy and the float's own weight when the reservoir level drops below the set value. It is.

이와 같은 본 발명의 하역기의 분진 방지용 급수제어장치는 저수조에 급수되는 물의 부력을 이용하여 설정범위에서 급수를 차단함으로써, 급수초과로 인하여 저수조가 넘치는 현상을 예방하여 오탁수가 바다로 유입 되는 환경오염을 방지하고 물이 소모되는 량에 따라 부력과 그 자중에 의해 밸브를 오픈시키게 되어 저수조에 물이 급수되지 않는 문제점을 방지할 수 있다.Such a water supply control device for dust prevention of the unloading machine of the present invention blocks the water supply in the set range by using the buoyancy of the water supplied to the reservoir, thereby preventing the overflow of the reservoir due to the excess of the water supply to prevent the environmental pollution that the filthy water flows into the sea. The valve is opened by buoyancy and its own weight according to the amount of water consumed, thereby preventing the problem that water is not supplied to the reservoir.

또한, 고가의 솔레노이드 밸브를 사용한 경우에 비해 구조가 간단하고 고장방지로 인한 비용절감 효과는 물론 작업지연 및 정비로 인한 손해를 최소화 할 수 있는 장점도 있다.In addition, compared to the case of using an expensive solenoid valve, the structure is simple, and the cost saving effect due to failure prevention, as well as minimizing damage due to work delay and maintenance.
