Description
본 고안은 중량물 이송용 크레인의 흔들림을 측정하기 위한 장치에 관한 것으로서, 보다 상세하게는 보다 안정적이고 정확하면서 고장발생없이 2차원 흔들림각도를 측정할 수 있도록 된 크레인의 2차원 흔들림각도 측정장치에 관한 것이다.The present invention relates to a device for measuring the shaking of a crane for transporting heavy materials, and more particularly, to a two-dimensional shaking angle measuring device of a crane that can measure a two-dimensional shaking angle more stably and accurately without failure will be.
일반적으로 각종 중량물(예를들어, 제철소의 각종 제품들, 부두의 컨테이너 및 건설현장의 각종 자재들)을 이송하기 위한 설비중 크레인의 운전은, 전문 운전자에 의존하고 있다. 그러나, 이러한 크레인은 중량물을 이송하기 때문에, 반복적인 운전으로 운전자의 집중력이 떨어질 경우, 대형 안전사고를 유발하는등 많은 문제점을 야기해 왔다.In general, the operation of a crane in a facility for transporting various heavy materials (for example, various products of an ironworks, containers of a pier, and various materials of a construction site) depends on a professional driver. However, since these cranes carry heavy loads, when the driver's concentration decreases due to repetitive driving, many problems have occurred such as causing a large safety accident.
최근에 자동화기술의 발전과 더불어 크레인 운전을 무인화하려는 연구도 매우 많이 활성화되어 왔으며, 지금도 크레인무인화를 위해서 다각도로 작업이 진행되고 있다.Recently, with the development of automation technology, researches to unmanned crane operation have been very active, and work is being carried out at various angles for unmanned cranes.
크레인 운전을 무인화하기 위해서 필요한 핵심기술은, 크레인이 이동할 때 발생하는 중량물의 흔들림을 방지하는 기술이며, 이를 위하여는 중량물이 얼마나 흔들리고 있는지를 정확하게 측정하는 것이 반드시 선행된다.The core technology required for unmanned crane operation is a technique for preventing the shaking of heavy weight generated when the crane moves, and for this purpose, it is necessary to accurately measure how much the heavy weight shakes.
중량물의 2차원 흔들림을 정밀하게 측정하는 장치 및 방법으로는 대한민국 실용신안등록출원 제94-39349호, 96-28726호, 97-39510호등을 들수 있다.Apparatus and method for precisely measuring the two-dimensional shaking of heavy materials include Korean Utility Model Registration Nos. 94-39349, 96-28726, 97-39510, and the like.
상기 언급한 종래기술의 장치를 산업현장에 사용하기 위하여는 개선해야 할 장치가 반드시 필요하며, 그 이유는 다음과 같다. 실제 현장에서 사용되는 크레인은 거더/트롤리와 중량물 이송부 사이의 거리가 항만 크레인의 경우는 50m 이상이 될 수도 있으며, 짧아도 10m 이상이 된다. 이러한 경우 각도측정을 위해서 각도측정부와 중량물이송부 사이에서 일정 장력을 유지하기 위한 장력조절부는 올바른 기능을 할 수 없으며, 특히 옥외 크레인의 경우 바람이 심하게 부는 경우 각도측정부와 장력조절부 사이의 줄의 흔들림으로 인하여 실제 중량물의 흔들림과는 다른 크기의 흔들림을 측정하기 때문에 잘못된 제어로 중량물을 떨어뜨릴 수도 있다. 또한, 중량물 이송시의 호이스트(hoist) 작업의 반복(실제 현장크레인의 작업시에는 이런 작업이 많이 발생한다)은 장력조절부의 수명을 단축시켜 유지보수비를 매우 많이 들게 하고, 심한 경우 장력조절부의 줄이 끊어지는 경우는 작업의 중지시간이 매우 길어지는 등 여러 가지 문제점을 야기하고 있다.In order to use the above-mentioned devices of the prior art in an industrial field, an apparatus to be improved is absolutely necessary. In the actual crane used, the distance between the girder / trolley and the heavy load transfer part may be 50m or more for a port crane, and even 10m or more for a short time. In this case, the tension adjusting part for maintaining a constant tension between the angle measuring part and the heavy material conveying part for the angle measurement can not function properly, especially in the case of heavy wind in the outdoor crane between the angle measuring part and the tension adjusting part Due to the shaking of the string, the weight of the weight is measured differently from the shaking of the actual weight, so the weight may be dropped by wrong control. In addition, the repetition of hoist work during heavy weight transfer (this work occurs a lot in the case of actual field crane work) shortens the service life of the tension control part, which leads to very high maintenance costs and, in severe cases, reduces the tension control part. This breakage causes various problems such as extremely long downtime of work.
본 고안은 이러한 종래의 문제점을 해소하기 위하여 안출된 것으로서 그 목적은, 크레인의 무인화를 위해 중량물 흔들림을 보다 정확하고 안전하면서 설비의 고장없이 측정할 수 있도록 된 크레인의 2차원 흔들림각도 측정장치를 제공함에 있다.The present invention has been devised to solve such a conventional problem, and its purpose is to provide a two-dimensional swing angle measuring device of a crane that can more accurately and safely measure the weight shaking for unmanned crane without failure of equipment.

이하, 본 고안의 바람직한 일실시예를 첨부된 도면에 의거하여 보다 상세하게 설명하고자 한다.Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.
도1은 종래에 사용하고 있는 2차원측정장치의 정면도이고, 도2는 도1의 측면도로서, 이러한 종래의 장치는 거더/트롤리(5)의 하부면에 각도측정부(3)를 두며, 상기 각도측정부(3)와 중량물 이송부(6)의 드럼(12)에 갖추어진 장력조절부(1)가 장력조절줄(2)을 매개로 연결되며, 따라서 중량물이송부(6)가 중량물을 이송중에 흔들리는 경우, 그 흔들림이 장력조절줄(2)을 통해 각도측정부(3)에 전달됨으로서 상기 각도측정부(3)에서 중량물의 2차원흔들림을 측정하는 것이다. 물론, 이러한 종래의 장치에 있어서는, 중량물이 흔들리지 않는 초기상태에서 장력조절줄(2)이 수직한 상태에 있어야 하며, 이러한 조건이 만족되지 않는 경우에는 중량물이 흔들리지 않고 있는데도 각도측정부(3)에서는 중량물이 흔들리고 있다고 판단하게 된다.Fig. 1 is a front view of a conventional two-dimensional measuring device, and Fig. 2 is a side view of Fig. 1, which has an angle measuring unit 3 on the lower surface of the girder / trolley 5, The tension adjusting unit 1 provided in the angle measuring unit 3 and the drum 12 of the heavy material conveying unit 6 is connected through the tension adjusting line 2, and thus the heavy material conveying unit 6 conveys the heavy object. In the case of shaking in the middle, the shaking is transmitted to the angle measuring unit 3 through the tension adjusting line 2 to measure the two-dimensional shaking of the weight in the angle measuring unit 3. Of course, in such a conventional apparatus, the tension adjusting line (2) should be in a vertical state in the initial state in which the heavy object does not shake, and if the condition is not satisfied, the angle measuring unit (3) It is determined that the weight is shaking.
이러한 종래의 장치는, 거더/트롤리(5)의 고정점(7)에 매달린 와이어로프(4)가 중량물이송부(6)에 갖추어진 드럼(12)을 통해 거더/트롤리(5)의 드럼(11)에 연결되어 있으며, 호이스트 운동에 따라서 와이어로프(4)가 거더/트롤리 드럼(11)에 감기거나 풀리게 된다. 이에 따라서, 장력조절부(1)는 장력조절줄(2)에 일정한 장력을 유지시키기 위하여 장력조절줄(2)을 풀거나 감게된다. 상기에서 언급하였듯이 이와같은 장치의 구성에서는, 장력조절부(1)에 고장이 발생하거나 장력조절줄(2)이 끊어지는 경우에는 중량물의 흔들림 각도를 측정할 수가 없다. 또한, 호이스트 운동거리가 긴 경우(실제로 항만 크레인의 경우는 호이스트 운동거리가 매우 길다)에는 전체 호이스트 운동거리동안 장력조절부(1)가 장력조절줄(2)에 항상 원하는 장력을 걸어주는 것이 거의 불가능하다. 설사 가능할지라도 그를 위하여는 복잡하고 정밀한 장치를 요구하여 제작 단가가 기하급수적으로 상승하므로 사실상 사용불가능한 것이 현실이다. 또한, 호이스트 운동거리가 짧더라도 반복운동의 결과로 장력조절부(1)의 성능이 저하되는 경우가 발생함으로 인해 원하는 장력을 발생시키지 못하여 상기 언급한 거더/트롤리(5) 면에 대한 장력조절줄(2)의 연직하방조건을 만족하지 못하는 경우도 발생하는등 유지보수가 곤란하다.Such a conventional apparatus comprises a drum of the girder / trolley 5 via a drum 12 having a wire rope 4 suspended in the fixed point 7 of the girder / trolley 5 on the heavy material conveying portion 6. 11), the wire rope 4 is wound or unwound on the girder / trolley drum 11 according to the hoist movement. Accordingly, the tension control unit 1 is to unwind or wind the tension control line (2) to maintain a constant tension in the tension control line (2). As mentioned above, in the configuration of such a device, when a failure occurs in the tension adjusting unit 1 or the tension adjusting line 2 is broken, the shaking angle of the heavy material cannot be measured. In addition, when the hoist movement distance is long (actually, the hoist movement distance is very long in the case of a port crane), it is almost impossible for the tension control unit 1 to always apply the desired tension to the tension control line 2 during the entire hoist movement distance. impossible. Even if it is possible, the reality is that it cannot be used because the manufacturing cost increases exponentially because it requires a complicated and precise device. In addition, even if the hoist movement distance is short, the performance of the tension control unit 1 is reduced as a result of repeated movements, so that the tension control line for the girder / trolley 5 surface mentioned above cannot be generated. Maintenance is difficult, such as when the vertical down condition of (2) is not satisfied.
도3은 본 고안에 따른 크레인의 2차원 흔들림각도 측정장치를 도시한 정면도이고, 도4는 도3의 측면도로서, 본 고안에서는 거더/트롤리(5)의 하부에 장착된 각도측정부(3)가 와이어로프(4)에 직접 연결되어 있음을 보인다.Figure 3 is a front view showing a two-dimensional shaking angle measuring device of the crane according to the present invention, Figure 4 is a side view of Figure 3, in the present invention the angle measuring unit (3) mounted to the bottom of the girder / trolley (5) Is connected directly to the wire rope 4.

그리고, 상기 와이어로프관통부(8)는 레버(10)를 매개로 각도측정부(3)에 연결되며, 상기 각도측정부(3)의 설치된 위치에 따라 레버(10)의 형상이 다양하게 이루어질 것이다. 본 고안에서는, 상하승강하지 않는 와이어로프(4)에 와이어로프관통부(8)를 설치하고, 상하승강하는 와이어로프(4)와 상하승강하지 않는 와이어로프(4)가 이루는 사각형의 중심부에 각도측정부(3)가 설치되며, 따라서 상기 레버(10)는 'ㄷ'자형 연결레버의 양단부가 와이어로프관통부(8)에 연결되고 이러한 'ㄷ'자형 연결레버의 중앙부가 각도측정부(3)의 수직한 연결레버에 고정되도록 형성되는 것을 알 수 있다.In addition, the wire rope through portion (8) is connected to the angle measuring unit (3) via the lever 10, the shape of the lever 10 is made variously depending on the installed position of the angle measuring unit (3). will be. In the present invention, the wire rope through portion 8 is provided on the wire rope 4 which does not move up and down, and the angle is formed at the center of the square formed by the wire rope 4 which moves up and down and the wire rope 4 which does not move up and down. The measuring unit 3 is installed, and thus the lever 10 has both ends of the 'c' shaped connecting lever connected to the wire rope through section 8 and the central portion of the 'c' shaped connecting lever is an angle measuring unit 3. It can be seen that is formed to be fixed to the vertical connecting lever of).
물론, 상기 와이어로프관통부(8)가 하나 설치되어 있는 경우, 그 와이어로프관통부(8)의 직상부측 거더/트롤리(5)에 각도측정부(3)를 설치하여 직선형 레버에 의해 와이어로프관통부(8)와 각도측정부(3)를 직접 연결하여도 좋고, 상기 와이어로프관통부(8)가 상기와 같이 복수개 설치되어 있는 경우, 그들 와이어로프관통부(8)를 직선형 레버로 서로 연결한 후 와이어로프관통부(8) 사이의 직상부측 거더/트롤리(5)에 각도측정부(3)를 설치하여 직선형 레버의 중앙부와 각도측정부(3)를 또다른 직선형레버에 의해 연결하여도 좋으며, 이는 다양한 구성이 도출될 수 있음을 설명한 것이다.Of course, in the case where one wire rope through portion 8 is provided, the angle measuring portion 3 is provided in the upper girder / trolley 5 of the wire rope through portion 8 and the wire is connected by a straight lever. The rope through portion 8 and the angle measuring portion 3 may be directly connected. When the wire rope through portions 8 are provided in plural as described above, the wire rope through portions 8 are connected with a straight lever. After connecting to each other, the angle measuring part 3 is installed in the upper girder / trolley 5 between the wire rope through parts 8, and the center of the straight lever and the angle measuring part 3 are connected by another straight lever.

또한, 본 고안의 장치를 보다 정확하게 운용하기 위하여는, 중량물이 흔들리지 않는 초기상태에 있을 때, 와이어로프(4)들이 수직한 상태를 유지하고 있을 것이 요구된다.In addition, in order to operate the device of the present invention more accurately, it is required that the wire ropes 4 remain vertical when the weight is in an unstable initial state.
