본 발명은 원료등을 수송하는 벨트콘베이어 설비에서 원료를 수송하는 보조 설비인 벨트 받침롤러에 관한 것으로, 보다 상세히는 회전작동시 베어링에 의하여 내부의 온도가 상승하는 것을 억제하여 베어링의 수명을 연장시킴과 동시에, 내구성을 향상시키고, 몸체의 변형을 방지하여 벨트의 손상을 방지하도록 개선된 공냉식 받침롤러에 관한 것이다.The present invention relates to a belt support roller that is an auxiliary facility for transporting raw materials in a belt conveyor facility for transporting raw materials, and more particularly, to prolong the life of the bearing by suppressing an increase in the internal temperature by the bearing during rotation operation. At the same time, the present invention relates to an air-cooled support roller which is improved to improve durability and prevent deformation of the body to prevent damage to the belt.

일반적으로 벨트 콘베이어설비(100)는 다수개의 받침롤러(110)들을 갖추고 그 상부측에 벨트(120)가 놓여져서 이동함으로서 벨트(120)의 상부면에 실린 이송물(130)을 목적지까지 이동시키게 된다. 이러한 롤러(110)들은 도 1에 도시된 바와 같이, 벨트(120)를 전,후진시키기 위하여 회전하게 되며, 벨트(120)를 지지하는 원통형 몸체(112)의 회전을 원활하게 하기 위하여 롤러(110)의 중심축(114)과 몸체(112)사이에는 각각 베어링(116)들이 개재되어 있다.In general, the belt conveyor facility 100 is equipped with a plurality of support rollers 110 and the belt 120 is placed on the upper side to move the conveying material 130 loaded on the upper surface of the belt 120 to the destination. do. Such rollers 110 are rotated to move the belt 120 forward and backward, as shown in FIG. 1, and the rollers 110 to smoothly rotate the cylindrical body 112 supporting the belt 120. Bearings 116 are interposed between the central axis 114 and the body 112.

이러한 벨트 콘베이어의 받침롤러(110)들은 각각 운반물에 따라서, 다소 차이는 있지만, 제철소의 원료를 수송하는 벨트 콘베이어(100)에서는 광석및 석탄을 수송하기 위하여 고속으로 회전되고 있다. 즉, 광석을 수송하기 위해서는 벨트(120)를 분당 135미터(롤러의 분당 26회전)를, 석탄을 수송하기 위해서는 벨트(120)를 분당 270미터(롤러의 회전 52회)의 속도로 가동하고 있다. The support rollers 110 of such a belt conveyor are rotated at high speed to transport ore and coal in the belt conveyor 100 for transporting raw materials of steel mills, although there are some differences depending on the package. That is, the belt 120 is operated at a speed of 135 meters per minute (26 revolutions per minute of the roller) per minute for transporting the ore, and the belt 120 is operated at a speed of 270 meters per minute (52 rotations of the roller) for transporting coal. .

그러나, 종래의 기술에 따른 롤러(100)는 롤러의 회전이 고속일수록 베어링(116)의 자체 열이 상승되지만, 롤러(110)의 내부는 밀폐되어 별다른 냉각수단이 없기 때문에, 롤러(110)내부에 열이 존재하는 상태로 장시간 고속회전하면 내부의 열이 더욱 증가하여 베어링(116) 내의 그리스의 점도가 저하되면서 그리스가 흘러내려 롤러(110)의 회전시 베어링(116)의 파손으로 롤러(110)가 조기에 마모되 고, 롤러(110)의 회전균형이 맞지않게 되어 벨트(120)의 사행을 초래한다. 즉, 받침롤러(110)의 좌,우측 회전균형이 맞지 않고 어느 한측이 높거나 낮으면, 이는 바로 벨트(120)의 한쪽 쏠림을 유발시키고, 결국은 벨트(120)의 사행이 초래되어 벨트의 양측 모서리가 손상되며, 조기 교체에 따른 설비 가동율이 저하되는 것이다. However, in the roller 100 according to the related art, the higher the rotation of the roller is, the higher the heat of the bearing 116 increases, but since the inside of the roller 110 is sealed and there is no cooling means, the inside of the roller 110 When high-speed rotation for a long time in the state of heat is present, the internal heat is further increased, the viscosity of the grease in the bearing 116 is lowered, the grease flows down and the roller 110 is damaged due to breakage of the bearing 116 when the roller 110 is rotated. ) Is prematurely worn, and the rotational balance of the roller 110 is not matched, resulting in meandering of the belt 120. That is, if the left and right rotation balance of the support roller 110 is not matched and either side is high or low, this causes one side of the belt 120 to be pulled out, and eventually the meandering of the belt 120 is caused to Both edges are damaged and the capacity utilization rate is reduced due to early replacement.

본 발명은 상기와 같은 종래의 문제점을 해소하기 위한 것으로서, 그 목적은 벨트가 진행함에 따라서 몸체의 회전작동시, 베어링에 의하여 내부의 온도가 상승하는 것을 억제하여 베어링의 수명을 연장시킴과 동시에, 내구성을 향상시키고, 몸체의 변형을 방지하여 벨트의 손상을 방지하도록 개선된 공냉식 받침롤러를 제공함에 있는 것이다.The present invention is to solve the conventional problems as described above, the object is to prolong the life of the bearing by suppressing the increase in the internal temperature by the bearing during the rotation operation of the body as the belt proceeds, The present invention provides an air-cooled backing roller that is improved to improve durability and prevent deformation of the body to prevent damage to the belt.

In order to achieve the above object, the present invention is a support roller for rotatably supporting a belt which is an auxiliary equipment for transporting raw materials in a belt conveyor equipment for transporting raw materials, etc., both flanges of the body to the outside of the bearing Each of them forms a plurality of holes to allow the outside air of the body to circulate to the inside, and a plurality of heat dissipation holes are formed in the side plate to which the bearing is fixed so that the heat generated from the bearings is dissipated when the body rotates. By providing an air-cooled support roller, characterized in that configured to prevent the temperature rise.

그리고, 본 발명은 제 1항에 있어서, 상기 몸체의 내주면에 다수의 유선형 날개들을 부착하여 상기 몸체가 중심축을 중심으로 회전하는 경우, 그 날개 구조로 인하여 몸체의 내부에서 일측으로 부터 타측으로 향하는 공기흐름을 형성하고, 그에 따라서 공기가 유입되는 상류측에는 압력이 낮아져서 몸체내로 외부로 부터 공기가 유입되고, 타측은 압력이 높아져서 몸체의 내부로 부터 구멍들을 통하여 외부로 나가서 몸체내부의 열을 외부로 발산하도록 구성되는 공냉식 받침롤러를 제공한다.And, according to the present invention, when the body is rotated about the central axis by attaching a plurality of streamlined wings to the inner peripheral surface of the body, due to the wing structure air from one side to the other side from the inside of the body As a result, the pressure is lowered on the upstream side where the air is introduced, so that the air is introduced from the outside into the body, and the pressure is increased on the other side, which goes out through the holes from the inside of the body to dissipate heat inside the body to the outside. To provide an air-cooled backing roller configured to.

이하, 본 발명을 도면에 따라서 보다 상세히 설명한다.Hereinafter, the present invention will be described in more detail with reference to the drawings.

The air-cooled support roller 1 according to the present invention is to support the belt 120, which is an auxiliary facility for transporting raw materials, in a belt conveyor facility for transporting raw materials, such as to rotate, as shown in cross section in FIG. A central shaft 114 is disposed at the center of the body 112, and the body 112 is connected to the central shaft 114 by bearings 116 at both flange 10 portions so that the body 112 is rotatable. Has a structure.

동시에 상기 양측 플랜지(10)에는 중앙에 장착된 베어링(116)의 외측으로 각각 다수개의 구멍(12), 바람직하게는 원주방향으로 각각 등간격의 분포를 가지는 4개, 또는 그 이상의 개수를 갖는 구멍(12)들을 형성하여 몸체(112)의 내부와 외부가 연통하도록 된다.At the same time, the two flanges 10 each have a plurality of holes 12, preferably four or more, each having an evenly spaced distribution in the circumferential direction to the outside of the centrally mounted bearing 116. (12) are formed so that the inside and the outside of the body 112 is in communication.

따라서, 상기 구멍(12)들을 통하여 내,외부공기가 서로 순환되고, 이러한 몸체(112) 내,외부의 공기 순환을 촉진하기 위하여 상기 몸체(112)의 내주면에는 다수의 유선형 날개(15)들을 부착한다. 상기 날개(15)들은 몸체(112)의 내주면에서 길이방향및 원주방향으로 일정간격을 유지하면서 몸체(112)의 일측으로 부터 타측으로 향하여 각각 다수개가 형성된 것으로, 마치 송풍팬의 블레이드와 같이 다수개 가 형성된다. Therefore, internal and external air circulates through each other through the holes 12, and a plurality of streamlined wings 15 are attached to the inner circumferential surface of the body 112 to promote circulation of air in and out of the body 112. do. The wings 15 are each formed in a plurality from the one side of the body 112 to the other side while maintaining a constant distance in the longitudinal direction and the circumferential direction on the inner circumferential surface of the body 112, a plurality of like a blade of the blowing fan Is formed.

따라서, 상기 날개(15)들은 몸체(112)가 중심축(114)을 중심으로 회전하는 경우, 그 돌출된 날개(15)구조로 인하여 몸체(112)의 내부에서 일측으로 부터 타측으로 향하는 공기흐름을 형성하고, 그에 따라서 공기가 유입되는 상류측에는 압력이 낮아져서 몸체(112)내로 외부로 부터 공기가 유입되고, 타측은 압력이 높아져서 몸체(112)의 내부로 부터 구멍(12)들을 통하여 외부로 나간다. Therefore, the wings 15 are air flows from one side to the other in the interior of the body 112 due to the structure of the protruding wing 15, when the body 112 rotates about the central axis 114, The pressure is lowered on the upstream side where air is introduced, thereby introducing air from the outside into the body 112, and the other side is pressurized to go out through the holes 12 from the inside of the body 112. .

그리고, 상기 플랜지(10)에 형성되어 상기 베어링(116)이 고정되어지는 측판(25)에는 다수개의 열발산 구멍(27)이 형성되고, 이들 구멍(27)은 도5에 도시된 바와 같이 4개 또는 그 이상이 형성되며, 몸체(112)의 회전시 베어링(116)에서 발생된 열이 발산되도록 하여 몸체(112)의 내부온도 상승을 방지하도록 구성되는 것이다.In addition, a plurality of heat dissipation holes 27 are formed in the side plate 25 formed in the flange 10 to which the bearing 116 is fixed, and these holes 27 are formed as shown in FIG. 5.
