Description
본 발명은 찢김방지용 코드가 내장된 제철소 및 산업용 컨베이어벨트에 관한 것으로, 특히 제철소 및 산업용 컨베이어벨트 내부에 폭방향으로 찢김방지용 코드를 내장하므로써 컨베이어벨트의 일정부분만 손상되도록 하기 위한 제철소 및 산업용 컨베이어벨트에 관한 것이다. The present invention relates to steelworks and industrial conveyor belts with a built-in tear prevention cord, in particular steel mills and industrial conveyor belt to damage only a portion of the conveyor belt by embedding the tear prevention code in the width direction inside the steelworks and industrial conveyor belt. It is about.
종래의 제철소 및 산업용 컨베이어장치(100)는 제철소 및 일반 산업분야에 사용되어지는 철광석 및 코우크스, 원석, 석탄, 시멘트등을 이송하기 위한 것으로, 상당한 양의 물량과 장거리를 운송하여야 하기 때문에 상기 장치의 컨베이어벨트(110)는 매우 질기고 내구성이 우수한 구조를 가져야 한다.Conventional steel mill and industrial conveyor apparatus 100 is for transporting iron ore and coke, ore, coal, cement, etc. that are used in steel mills and general industrial fields, because the apparatus must be transported a considerable amount and long distance The conveyor belt 110 should have a very tough and durable structure.
따라서 상기 컨베이어벨트(110)는 도 1 내지 3도에 도시한 바와 같이 쿳션고무(111)의 내부에 컨베이어벨트의 길이방향으로 형성된 코드(112)가 삽입되어 있으며, 그 위에 커버고무(113)를 피복하여서 된 구조를 갖는다.Therefore, the conveyor belt 110 has a cord 112 formed in the longitudinal direction of the conveyor belt is inserted into the cushion rubber 111, as shown in Figures 1 to 3, the cover rubber 113 thereon It has a structure made by covering.
그러므로 상기한 구조를 갖는 종래의 컨베이어벨트(110)는 벨트 내부에 컨베이어벨트의 길이방향을 따라 형성되는 스틸 코드나 합성수지섬유재질의 길이방향 코드(112)를 삽입하므로써 벨트의 내구성 및 인장강도을 좋게 하고 있으나, 상기 코드(112)가 컨베이어벨트의 길이방향으로만 형성되어 있어 만일 컨베이어벨트(110) 위에 이물질이 끼어 벨트 크리너(cleaner)및 컨베이어벨트 부대시설에 걸리게 되거나 컨베이어벨트롤러가 회전불량에 의해 마모되어 칼날같이 변하게 된 경우 한번 찢기기 시작한 컨베이어벨트(110)는 길이방향으로 한없이 손상되어진다.Therefore, the conventional conveyor belt 110 having the above structure improves the durability and tensile strength of the belt by inserting the steel cord or the longitudinal cord 112 formed in the longitudinal direction of the conveyor belt into the belt. However, the cord 112 is formed only in the longitudinal direction of the conveyor belt, so if foreign matters are caught on the conveyor belt 110, the belt cleaner and the conveyor belt may be caught, or the conveyor belt controller may be worn out due to a poor rotation. When the conveyor belt 110 is torn once it is changed like a blade is damaged indefinitely in the longitudinal direction.
이는 상기 컨베이어벨트(110)의 폭방향, 즉 컨베이어벨트(110)의 폭방향으로는 아무런 제제수단이 형성되어 있지 않기 때문이며, 이로인해 광양제철소에 소재하고 있는 컨베이어벨트는 무려 5km정도가 찢겨 엄청난 경제적 손실은 물론 심각한 조업차질을 빚은 바 있으며, 또한 화력발전소, 시멘트 제조운반용 컨베이어벨트 조업현장등에서도 항상 문제의 발생소지를 안고 있으며 이를 해결하기 위한 방안이 절실히 요구되고 있는 실정이다.This is because no preparation means are formed in the width direction of the conveyor belt 110, that is, in the width direction of the conveyor belt 110. As a result, the conveyor belt located in Gwangyang Works is torn about 5km, resulting in tremendous economic benefits. In addition to the loss, there have been serious operational disruptions, and there is always a problem in the thermal power plant, the operation site of the conveyor belt for cement production transportation, and there is an urgent need for a solution to solve this problem.
따라서 본 발명은 상기한 바와같은 종래의 제철소 및 산업용 컨베이어벨트가 갖는 단점을 해결하기 위해 창안된 것으로, 종래 길이방향으로 찢김방지용 코드가 내장되어 있는 제철소 및 산업용 컨베이어벨트에 컨베이어벨트의 폭방향, 즉 컨베이어벨트의 폭방향으로도 찢김방지용 코드를 형성하되 일정간격으로 이격되어 이를 형성함으로써 설사 컨베이어벨트와 벨트 크리너 및 컨베이어벨트 부대시설 사이에 이물질이 끼었다 하더라도 폭방향으로 형성된 찢김방지용 코드에 의해 이물질이 튀겨나가도록 구성하므로써 컨베이어벨트의 손상을 최소화 할 수 있도록 하기 위한 찢김방지용 코드가 내장된 제철소 및 산업용 컨베이어벨트를 제공하기 위한 것이다. Therefore, the present invention was devised to solve the disadvantages of the conventional steel mill and industrial conveyor belt as described above, the width direction of the conveyor belt in the steel mill and industrial conveyor belt that is conventionally embedded in the longitudinal tearing code Forming a tear prevention cord in the width direction of the conveyor belt, but by forming a space to be spaced apart at regular intervals, even if foreign matter is caught between the conveyor belt and the belt cleaner and the conveyor belt auxiliary facilities, foreign matter is splashed by the tear prevention cord formed in the width direction. It is to provide steel mills and industrial conveyor belts with a built-in tear prevention code for minimizing damage to the conveyor belt by being configured to go out.
본 발명을 첨부한 도면에 의해 상세히 설명하면 다음과 같다.The present invention will be described in detail with reference to the accompanying drawings.
본 발명은 제철소 및 산업용 컨베이어벨트에 있어서, 종래 컨베이어벨트를 따라 형성된 길이방향 코드(112)의 상부면에 폭방향으로 3~7개의 찢김방지용 코드(210)를 2~5cm간격으로 이격되도록 배열하여 일군의 찢김방지용 코드(210A)가 형성되도록 하고, 상기 일군의 찢김방지용 코드(210A)는 다시 각각 30~70m간격으로 이격되도록 배치함으로써 제철소 및 산업용 컨베이어벨트의 찢김, 즉 손상부(A)의 길이를 최소화 할 수 있도록 한 것이다.The present invention in the steel mill and industrial conveyor belt, by arranging the three to seven tear-resistant cord 210 in the width direction on the upper surface of the longitudinal cord 112 formed along the conventional conveyor belt spaced apart at 2 ~ 5cm intervals A group of tear prevention cords 210A are formed, and the group of tear prevention cords 210A is disposed to be spaced apart at intervals of 30 to 70 m, respectively, so that the steel sheet and industrial conveyor belts are torn, that is, the length of the damaged part A. To minimize it.
이때 일군(一群)의 찢김방지용 코드(210A)를 형성하기 위해 필요한 찢김방지용 코드(210)의 갯수는 3~7개이며, 상기 찢김방지용 코드(210)의 갯수가 3개이하인 경우는 찢김방지용 코드(210)의 갯수가 너무 적어 이물질로 인한 컨베이어벨트의 찢어짐을 방지하기 곤란하고, 7개 이상인 경우에는 불필요하게 너무 많이 형성될 경우 비경제적이다. 따라서 이물질로 인한 찢어짐 방지 및 경제성을 감안할 경우 가장 바람직한 찢김방지용 코드(210)의 갯수는 4~5개이다.At this time, the number of tear prevention cords 210 required to form a group of tear prevention cords 210A is three to seven, and the number of tear prevention codes 210 when the number of tear prevention codes 210 is three or less. It is difficult to prevent the tearing of the conveyor belt due to foreign matters because the number of 210 is too small, it is uneconomical if too many are formed unnecessarily. Therefore, the most preferable number of tear prevention cords 210 is 4 to 5 in consideration of tearing prevention and economical efficiency due to foreign substances.
또한 상기 찢김방지용 코드(210)는 각각 2~5cm간격으로 이격되도록 배열되어짐이 바람직한데, 이는 상기 찢김방지용 코드(210)가 2cm이하일 경우에는 찢김방지용 코드(210)의 간격이 너무 촘촘하게 되어 이물질로 인한 충격을 흡수하기 곤란하게 되며, 상기 찢김방지용 코드(210)의 갯수가 5cm이상인 경우는 찢김방지용 코드(210)의 간격이 너무 성기게 형성되어 대개 벨트크리너와 컨베이어벨트 사이에 낀 이물질을 튕겨서 제거하고자 하는 본 발명의 목적을 달성하기가 곤란하기 때문이다.In addition, the tear prevention code 210 is preferably arranged so as to be spaced apart from each other 2 ~ 5cm interval, which is when the tear prevention code 210 is less than 2cm, the gap of the tear prevention code 210 is too tightly separated It is difficult to absorb the impact caused, and if the number of the tear prevention cords 210 is 5 cm or more, the gap between the tear prevention cords 210 is formed so sparsely that the foreign matter caught between the belt cleaner and the conveyor belt is removed by throwing them. This is because it is difficult to achieve the object of the present invention.
또한 상기 일군의 찢김방지용 코드(210A)의 이격길이는 30~70m간격이 바람직한데, 이는 일군의 찢김방지용 코드(210A)의 이격길이가 30m이하일 경우에는 너무 간격이 좁아져 일군의 찢김방지용 코드(210A)를 많이 필요로 하게 되고 이로인해 매우 비경제적인 단점을 갖는 것이고, 70m이상의 간격은 간격이 너무 넓어 컨베이어벨트의 찢김, 즉 손상부(A)가 발생할 경우 손상부의 길이가 길어지는 단점을 갖는 것이기 때문이다.In addition, the separation length of the tear prevention code 210A of the group is preferably 30 ~ 70m intervals, which is too narrow if the separation length of the tear prevention code 210A of the group is less than 30m a group of tear prevention code ( It requires a lot of 210A) and has a very uneconomical disadvantage, and the interval of more than 70m has a disadvantage that the length of the damaged part is long when the conveyor belt is torn, that is, when the damaged part A occurs. Because.
도 4 내지 도 5는 본 발명의 제 일실시예를 도시한 것으로, 상기 찢김방지용 코드(210)의 재질로 스틸코드(112)를 사용한 것을 도시한 것이다.4 to 5 illustrate a first embodiment of the present invention, which illustrates the use of the steel cord 112 as a material of the tear prevention cord 210.
도 6내지 도 7은 본 발명의 다른 실시예를 도시한 것으로, 상기 찢김방지용 코드(210)의 재질로 합성수지수지재질의 코드중에서도 폴리에스텔섬유를 사용한 것을 도시한 것이다.6 to 7 show another embodiment of the present invention, which shows that the polyester fiber is used among the cords of the synthetic resin material as the material of the tear prevention cord 210.
이처럼 본 발명은 컨베이어벨트의 폭방향으로도 찢김방지용 코드를 형성하므로써 컨베이어벨트와 벨트 크리너 사이에 이물질이 끼었다 하더라도 폭방향으로 형성된 찢김방지용 코드에 의해 이물질이 튀겨나가 컨베이어벨트의 손상을 최소화 할 수 있도록 한다.As such, the present invention forms a tear prevention code in the width direction of the conveyor belt so that even if foreign matter is caught between the conveyor belt and the belt cleaner, the foreign material is splashed by the tear prevention code formed in the width direction to minimize damage to the conveyor belt. do.
이처럼 본 발명은 제철소 및 산업용 컨베이어벨트의 폭방향으로 찢김방지용 코드를 가장 적당한 갯수로, 가장 적당한 간격으로 배치함으로써 컨베이어벨트와 벨트 크리너 및 컨베이어벨트 부대시설 사이에 낀 이물질을 제거할 수 있도록 한 것이며, 이물질에 의한 컨베이어벨트의 찢김, 즉 손상을 최소화 함으로써 경제적 손실을 감소시킴은 물론 수리시간을 최소화 할 수 있도록 하여 신속한 시간내에 조업을 재개할 수 있도록 하는 매우 유용한 발명인 것이다. As such, the present invention is to remove the foreign matter caught between the conveyor belt and the belt cleaner and the conveyor belt auxiliary facilities by arranging the tear prevention cords in the widthwise direction of steel mills and industrial conveyor belts at the most suitable number and at the most suitable intervals. It is a very useful invention to reduce the economic loss by minimizing the tear, ie damage of the conveyor belt by foreign matters, and to minimize the repair time and to resume operation in a short time.
