Description

벨트 콘베이어 과부하 방지장치{Apparatus for preventing the overload on the belt conveyor}Apparatus for preventing the overload on the belt conveyor}

본 발명은 선박으로부터 하역되는 원료를 이송하기 위한 벨트 콘베이어 상의 과부하를 방지하기 위한 장치에 관한 것이고, 더욱 상세하게는 선박을 통해 운반된 광석 및 석탄 등의 원료를 호퍼에 적재할 때 순간적으로 다량의 광석이 벨트 콘베이어 상부에 불출되어 발생되는 벨트 콘베이어 과부하를 간단하고 효율적으로 방지하여 환경 오염및 안전사고 예방과 하역효율을 향상 시킬수 있게한 하역용 벨트 콘베이어 과부하 방지장치에 관한 것이다.The present invention relates to an apparatus for preventing overload on a belt conveyor for transporting raw materials unloaded from a ship, and more particularly, when loading a raw material such as ore and coal transported through a vessel into a hopper in an instant. The present invention relates to a belt conveyor overload protection device for loading and unloading, which can prevent the belt conveyor overload caused by the ore being discharged to the upper part of the belt conveyor simply and efficiently, thereby preventing environmental pollution and safety accidents and improving the loading efficiency.

일반적으로, 선박을 통해 운반된 원료를 바켓(BUCKET)장치를 이용하여 호퍼에 하역하게 될때, 원료의 조건, 예를 들어 원료의 입도와 비중 수분 함량및 원료의 종류등의 조건과 호퍼 게이트 상태 등이 하역 작업중 광석의 순간 다량 불출로 인한 벨트 콘베이어의 과부하의 주요 원인이 되고 있다.In general, when unloading the raw material transported by ship to the hopper using a BUCKET device, the conditions of the raw material, for example, the conditions such as the particle size and specific gravity moisture content and the type of raw material and the state of the hopper gate This is a major cause of overload of the belt conveyor due to instantaneous large amount of ore discharge during unloading.

특히, 바켓으로 부터 과다한 량의 원료가 일시에 쏟아지면서 호퍼 게이트를 통과하게 되면, 순간적으로 많은 량의 원료가 벨트 콘베이어 상부에 쌓이게 되어 과부하가 발생하였다.In particular, when an excessive amount of raw material flows from the bucket and passes through the hopper gate, a large amount of raw material instantly accumulates on the belt conveyor, causing an overload.

도 1 및 도 2는 종래의 벨트 콘베어 상태를 나타낸 정면도 및 과부하 상태를 나타낸 정면도로서, 선박으로부터 바켓(도시하지 않음)에 의해 하역되는 원료는 경사면을 가진 호퍼(4)에 투입되어 낙하된 후, 그 하부의 공급부 호퍼게이트(7)와 피더(8)을 통해 제1벨트 콘베이어(5)에 불출되어 제2벨트 콘베이어(6)을 통해 부두 안벽라인(9)을 통해 야드에 이송된다.1 and 2 are a front view showing a state of a conventional belt conveyor and a front view showing an overload state, the raw material unloaded by the bucket (not shown) from the vessel is dropped into the hopper (4) having an inclined surface after falling The first belt conveyor 5 is discharged to the yard through the wharf wall line 9 through the second belt conveyor 6 through the feeder hopper gate 7 and the feeder 8 at the lower portion thereof.

상기 하역 작업중 선박으로부터 바켓에 담기는 양은 대략 30톤 내외의 많은 양이 되고, 이러한 과중한 양의 원료가 호퍼(4)에 쏟아질 때, 호퍼게이트(7)가 오픈되어 있을 경우, 많은 양의 원료가 일시에 벨트 콘베이어(5)의 상부에 쌓이게 되었다.During the unloading operation, the amount of the basket from the ship is about 30 tons, and when such a large amount of raw material is poured into the hopper 4, when the hopper gate 7 is opened, a large amount of raw material Accumulated at the top of the belt conveyor 5 at one time.

한편, 상기와 같은 벨트 콘베이어(5) 상의 과부하를 방지하기 위한 종래의 기술은 호퍼게이트(7)를 최대한 폐쇄(CLOSE) 시키고, 바켓을 조금씩 점차적으로 개방(OPEN)하는 방법으로 사람인 운전자의 순간적인 방심및 부주의에 의해 과부하가 발생되는 결함이 있었다.On the other hand, the prior art for preventing the overload on the belt conveyor (5) as close as possible (CLOSE) the hopper gate (7), by gradually opening the bucket gradually (OPEN) of the human driver There was a fault that caused overloading by carelessness and carelessness.

특히, 벨트 콘베이어(5) 상의 과부하 발생 시, 벨트 콘베이어(5)의 상부에 쌓인 원료는 본래의 공정과는 달리 작업자가 투입되어 삽을 이용한 수작업으로 과부하 복구작업이 이루어졌다.In particular, when the overload occurs on the belt conveyor (5), the raw material accumulated on the upper portion of the belt conveyor (5), unlike the original process, the worker was put into the overload recovery work was performed by hand using a shovel.

그리고, 벨트 콘베이어 상에 과부하를 유발시키는 원료는 작업자가 삽으로 벨트 콘베이어(5,6)의 하부 부두 육상으로 처리하게 되는 관계로 부두 환경 오염을 가중시키는 문제점이 있었다.In addition, the raw material causing the overload on the belt conveyor has a problem of increasing the environmental pollution of the dock due to the worker to be shoveled to the lower dock land of the belt conveyor (5,6).

또한, 많은 양의 원료(1)가 벨트 콘베이어 상부에 일시에 쌓이는 관계로 과중한 무게로 인해 롤러(2)가 파손되는 문제점을 유발시켰다.In addition, since a large amount of the raw material 1 is temporarily accumulated on the upper portion of the belt conveyor, the roller 2 is damaged due to heavy weight.

한편, 과부하 복구 작업이 수행되는 벨트 콘베이어(5) 상부, 호퍼게이트(7) 및 피더(8)의 하부는 공간이 협소하고 회전체 상부이며 작업중 호퍼(4)에 담긴 원료가 하부로 쏟아지는 등의 안전사고 위험이 상당히 높은 과부하 복구 작업의 특성에 의해 과부하 방지책이 더욱더 절실하게 요구되는 실정 이었다.On the other hand, the upper part of the belt conveyor (5), the hopper gate (7) and the lower part of the feeder (8) in which the overload recovery operation is performed, the space is narrow, the upper part of the rotor, and the raw material contained in the hopper (4) is poured into the lower part. Due to the nature of the overload recovery operation, which has a high risk of safety accidents, overload protection measures are urgently needed.

본 발명은, 상술된 바와 같이 선박으로부터 원료를 하역할 때 발생되는 문제점을 해결하기 위하여 안출한 것으로서, 호퍼로부터 원료의 낙하시 순간적으로 불출되는 다량의 원료를 이송시키기 위한 벨트 콘베이어 상의 과부하를 방지하기 위한 장치를 제공하는 데 그 목적이 있다.The present invention has been made to solve the problems caused when unloading the raw material from the vessel as described above, to prevent the overload on the belt conveyor for transferring a large amount of raw material instantaneously discharged when the raw material falls from the hopper. Its purpose is to provide a device for this purpose.

본 발명에 따르면, 상기 목적을 달성하기 위하여, 선박으로부터 바케트에 의해 호퍼에 하역되는 원료가 피다슈트를 통해 일시에 불출되어 벨트 콘베이어 상에과부하가 인가되는 것을 방지하기 위하여 상기 벨트 콘베이어 상에 장착되는 과부하 방지장치는 다수의 기어 및 다수의 가이드 롤러에 의해 지지되고 일측에 체결구가 형성된 한 쌍의 체인과, 상기 기어들중 한 쌍의 기어가 기어 커플링에 의해 결합되는 모터와, 상기 체인의 체결구에 체결봉이 핀으로 체결되고 지지대가 부착되어 있는 유도 브라켓트로 이루어진 것을 특징으로 한다.According to the present invention, in order to achieve the above object, the raw material unloaded to the hopper by the baget from the ship is mounted on the belt conveyor in order to prevent the overload is applied to the belt conveyor at one time through the feeder chute. The overload protection device is a pair of chains supported by a plurality of gears and a plurality of guide rollers and formed with fasteners on one side, a motor in which a pair of gears are coupled by gear coupling, and The fastening rod is fastened to the fastener by a pin, characterized in that consisting of the induction bracket is attached to the support.

먼저, 도 3은 본 발명의 실시예에 따른 과부하 방지장치의 설치 상태를 나타낸 정면도이고, 도 4 및 도 5는 본 발명의 실시예에 따른 과부하 방지장치를 상세하게 도시한 측면도 및 정면도이다.First, Figure 3 is a front view showing an installation state of the overload protection device according to an embodiment of the present invention, Figures 4 and 5 are a side view and a front view showing in detail the overload protection device according to an embodiment of the present invention.

제1벨트 콘베이어(5) 상측에 다수의 기어(12)와 다수의 가이드 롤러(13)에 의해 지지되는 한쌍의 체인(10)을 설치하고, 기어(12)와 기어 카플링(16)에 으로 모터(11)와 결합하되, 체인(10) 일측에 체결구(14)를 형성하여 유도 브라케트(20)에 부착된 체결봉(21)과 핀(24)으로 체결되고, 유도 브라케트(20) 일측에는 지지대(23)가 부착되어 있고, 피다슈트(3) 상측부에 감지봉(30)이 결합되고, 그 전방 벽면에 리미트 스위치(31)가 부설되어 있다.A pair of chains 10 supported by a plurality of gears 12 and a plurality of guide rollers 13 are installed on the upper side of the first belt conveyor 5, and the gear motor 12 is connected to the gears 12 and the gear coupling 16. Is coupled to (11), the fastener 14 is formed on one side of the chain 10 is fastened with a fastening rod 21 and a pin 24 attached to the induction bracket 20, the induction bracket 20 The support 23 is attached to one side, the sensing rod 30 is coupled to the upper side of the pida chute (3), the limit switch 31 is attached to the front wall surface.

따라서, 상기된 바와 같은 벨트 콘베이어 상의 과부하 방지장치는 바켓에 의해 선박으로부터 하역된 원료가 호퍼(4)에 적치되는 순간 바켓으로부터 낙하되는과중한 원료(1)가 일시적으로 불출되어 벨트 콘베이어(5) 상부에 많은 량의 원료(1)가 적치되는 것을 방지한다.Therefore, in the overload prevention device on the belt conveyor as described above, the heavy material 1 falling from the bucket is temporarily discharged from the moment when the material unloaded from the vessel by the bucket is placed in the hopper 4, and the upper part of the belt conveyor 5 is removed. The large amount of raw material 1 is prevented from being deposited.

즉, 감지봉(30)의 하측 일부가 간섭되어, 감지봉(30)이 리미트 스위치(31)를 터치함으로써 모터(11)를 작동시키게 된다. 또한, 모터(11)의 동력이 기어 커플링(10)을 통해 기어(12)에 전달되고, 그 회전력에 의해 체인(10)이 진행함에 따라 유도 브라케트(20)는 적정량 이상 적치된 원료(1)를 수송시키게 되어 과부하를 방지하는 작용을 한다.That is, the lower part of the sensing rod 30 is interfered with, so that the sensing rod 30 operates the motor 11 by touching the limit switch 31. In addition, the power of the motor 11 is transmitted to the gear 12 through the gear coupling 10, and as the chain 10 proceeds due to the rotational force, the induction bracket 20 is loaded with an appropriate amount of the raw material ( 1) is transported to prevent overload.
