롤러마모 방지용 스탠드장치{Roller stand assembly for preventing the wear of the roller}Roller stand preventing device {Roller stand assembly for preventing the wear of the roller}

본 발명은 벨트 부력부에 의한 롤러의 마모를 방지하기 위한 가위형 롤러 스탠드장치에 관한 것이고, 더욱 상세하게는 리크레머가 야드에 파일로 적치된 원료를 불출하여 수송할 때, 인접한 리크레머의 부력부에서 수송물의 중량에 의한 충격으로 발생되는 벨트의 조기마모 및 임팩트롤러의 파손을 방지하여 수송 효율을 향상시킬 수 있도록 하는 벨트 부력부의 가위형 롤러 스탠드에 관한 것이다.The present invention relates to a scissor-type roller stand device for preventing the wear of the roller by the belt buoyancy portion, and more particularly buoyancy of the adjacent recremer when the recremer is transported by discharging the raw material piled into the yard The present invention relates to a scissor-type roller stand for belt buoyancy, which improves transport efficiency by preventing premature wear of the belt and damage to the impact controller caused by the impact of the weight of the transport.

일반적으로, 벨트(2)를 이용하여 원료를 수송할 때, 설비의 조건, 예를 들어 벨트와 슈트의 거리가 멀어 낙하되는 원료의 충격이 벨트와 롤러에 가해진다. 따라서, 이러한 충격을 약화시키기 위하여 슈트 하부에 임팩트롤러가 제공된다.In general, when the raw material is transported using the belt 2, the conditions of the equipment, for example, the distance between the belt and the chute, is applied to the belt and the roller. Thus, an impact controller is provided at the bottom of the chute to dampen this impact.

그러나, 이러한 임팩트 롤러는 벨트 부력부를 형성하는 원인을 제공하게 된다. 그리고, 중량의 수송물이 적치된 벨트가 높은 곳으로 올라갈 때, 부력부에서 롤러에 인가되는 충격 등에 의해 벨트의 조기마모 및 롤러 편마모와 롤러 파손의 주요 원인을 제공한다.However, such impact rollers provide a cause of the belt buoyancy. And, when the belt loaded with the weight of the cargo is raised to a high place, it provides a major cause of premature wear of the belt and roller wear and roller breakage due to the impact applied to the roller in the buoyancy portion.

한편, 수평으로 배치된 지상롤러 상부로 수송물을 운반하던 벨트(2)가 중량의 원료를 싣고 오르막인 부력부를 올라갈 때, 부력부가 시작되는 전방롤러에 집중적으로 충격이 인가되어 상기 전방롤러의 마모 또는 파손을 야기시키게 된다. 특히, 롤러의 찌그러짐과 편마모 및 파손이 발생된 경우를 발견하지 못하고 계속하여 수송물을 수송하게 되면, 대략 2㎞ 길이 정도의 고가의 벨트가 절손되는 사고가 발생된다.On the other hand, when the belt 2 carrying the transport material on the horizontal rollers arranged horizontally goes up the buoyancy part which is the uphill load with the heavy material, the impact is intensively applied to the front roller where the buoyancy part starts, so that the front roller wears. Or cause breakage. In particular, if the roller is not crushed, unevenly worn, and damaged, and the transport is continuously carried out, an expensive belt of about 2 km in length is broken.

즉, 도 1을 참조하면, 벨트(2)는 지상과 수평으로 설치된 캐리어롤러 상부로 수송물을 수송하다가 부력부에서 상측으로 부력되어 오르막을 올라가는 구조이고, 다수개의 임팩트 롤러(7)를 설치하고, 벨트(2)와 슈트와의 거리를 좁히기 위하여 부력부를 형성한다.That is, referring to Figure 1, the belt (2) is a structure that transports the cargo to the upper surface of the carrier roller installed horizontally and buoyant upward from the buoyancy portion to climb uphill, and install a plurality of impact rollers (7) The buoyancy portion is formed to narrow the distance between the belt 2 and the chute.

상기 수송 작업중 벨트(2)에 실리는 수송물은 시간당 4000톤 정도의 과중한 중량이 되고 이러한 과중한 수송물을 수송하는 과정에서 벨트(2)에 실린 수송물의 중량과 벨트(2)의 속도에 의해 부력부(3)의 전방롤러에는 벨트(2)와 수송물이 부딪치는 것과 같은 과중한 충격이 인가되어 마모에 의한 찌그러짐 및 파손 등의 설비사고가 발생되었다.The conveyed goods on the belt 2 during the transporting operation become heavy weights of about 4000 tons per hour and buoyancy due to the weight of the conveyed goods on the belt 2 and the speed of the belt 2 in the process of transporting such heavy transports. Excessive shock such as the belt 2 and the transport object were applied to the front roller of the section 3, and equipment accidents such as crushing and damage due to abrasion occurred.

한편, 상기와 같은 충격에 의한 찌그러짐 및 파손 등의 설비사고를 방지하기 위하여 임팩트롤러(7)를 육안으로 점검하는 방법으로 점검중 롤러변형을 발견할 경우에는 임팩트롤러(7)를 교환하여 설비사고를 방지할 수 있었으나 야간에는 시야가 어두워 발견하지 못하는 결함이 있었다.On the other hand, in order to prevent equipment accidents such as crushing and damage caused by the impact as described above, if the impact deformation of the impact roller (7) is found during the inspection of the roller deformation during inspection by replacing the impact controller (7) It was able to prevent, but at night there was a dark field of vision was not found.

특히, 임팩트롤러(7)가 파손 될 경우 벨트(2)가 절손되는 설비사고가 동시에 발생되는 특성에 의해 롤러파손 방지책이 더욱더 절실하게 요구되는 실정이다.In particular, when the impact controller 7 is broken, the roller breakage prevention measures are more urgently required due to the characteristics that the equipment accident occurs at the same time that the belt 2 is broken.

본 발명은 상기된 바와 같은 종래의 제반 문제점을 해결하기 위하여 안출된 것으로, 수송물의 낙하 충격 및 벨트 부력부에 의해 인가되는 충격을 흡수하여 롤러마모나 파손 및 벨트 절손 등을 방지하여 수송 효율을 향상시킬 수 있도록 하는벨트 부력부의 가위형 롤러 스탠드장치를 제공하는 데 그 목적이 있다.The present invention has been made to solve the conventional problems as described above, by absorbing the drop impact of the transport and the impact applied by the belt buoyancy portion to prevent roller wear, breakage, belt break, etc. to improve the transport efficiency It is an object of the present invention to provide a scissor roller stand apparatus for belt buoyancy.
