이하, 본 발명에 따른 탄소섬유를 이용한 안전로프를 첨부된 도면에 의거하여 상세하게 설명하면 다음과 같다.Hereinafter, a safety rope using carbon fiber according to the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 탄소섬유를 이용한 안전로프의 일 예를 일부 발췌하여 보인 사시도이고, 도 2는 도 1의 탄소섬유를 이용한 안전로프 확대 단면도이다.FIG. 1 is a perspective view showing a part of a safety rope using carbon fiber according to the present invention, and FIG. 2 is an enlarged cross-sectional view of a safety rope using the carbon fiber of FIG. 1.

도 1,2의 본 발명에 따른 탄소섬유를 이용한 안전로프는, 지름이 작은 탄소섬유(10)와, 상기 탄소섬유 다수 개를 꼬아서 형성되는 심재(20)와, 상기 심재 수개를 꼬아서 형성되는 로프부재(30)와, 상기 로프부재를 유기바인더에 담가서 침투시키고 건져서 건조하여 수개의 심재들이 한 몸체로 되게 부착한 다음 일반적인 압출기를 사용하여 로프부재의 외면에 우레탄이 소정두께로 압출 피복되어 형성되는 외피부(40)로 구성되는 것을 특징으로 한다.The safety rope using carbon fiber according to the present invention as shown in Figs. 1 and 2 comprises a carbon fiber 10 having a small diameter, a core material 20 formed by twisting a plurality of the carbon fibers, The rope member is immersed in an organic binder, dried and dried, and several pieces of core material are attached so as to form one body. Then, urethane is extrusion-coated on the outer surface of the rope member using a general extruder And an outer skin (40) formed thereon.

탄소섬유(10)는 지름이 0.02~0.06㎜로 되며, 지름이 작고 가벼우면서도 인장 강도가 높고 난연성임은 물론 유연성과 내마모성 및 내화학약품성 등이 우수한 특징이 있다.The carbon fiber 10 has a diameter of 0.02 to 0.06 mm and is small in diameter and light in weight, yet has high tensile strength, flame retardancy, flexibility, abrasion resistance and chemical resistance.

심재(20)는, 원하는 지름에 따라 탄소섬유(10)의 개수를 선택하여 꼬아서 형성된다.The core member 20 is formed by twisting the number of the carbon fibers 10 according to a desired diameter.

또한, 로프부재(30)는 원하는 지름에 따라 심재(20)의 개수를 선택하여 꼬아서 형성되며, 이러한 상기 로프부재를 유기바인더가 수용된 탱크에 넣어 유기바인더가 침투되게 한 다음 꺼내서 건조한다.The rope member 30 is formed by twisting the number of the core members 20 according to a desired diameter. The rope member is put in a tank containing the organic binder to allow the organic binder to permeate, and then taken out and dried.

이렇게 하면, 로프부재(30)를 형성하는 탄소섬유(10)와 심재(20)들은 서로 부착되어 한 몸체로 되기 때문에 꼬아진 상태가 임의로 풀어지게 되는 현상이 발생하지 않게 된다.In this way, the carbon fibers 10 forming the rope member 30 and the core members 20 adhere to each other and become one body, so that a phenomenon that the twisted state is arbitrarily solved does not occur.

외피부(40)는, 압출기를 사용하여 유기바인더가 침투건조된 하나의 로프부재(30) 외면에 인장 강도가 높고 난연성과 유연성 및 내마모성을 갖는 우레탄을 소정두께로 압출시켜서 한 몸체로 피복되어 형성된다.The outer skin 40 is formed by extruding urethane having a high tensile strength, flame retardancy, flexibility and abrasion resistance to a predetermined thickness on the outer surface of one rope member 30 in which an organic binder is impregnated and dried by using an extruder, do.

이렇게 구성되는 탄소섬유를 이용한 안전로프는, 단면이 원형으로 된다.The safety rope using the carbon fiber thus constituted has a circular section.

도 3은 본 발명에 따른 탄소섬유를 이용한 안전로프의 다른 예를 일부를 발췌하여 보인 사시도이고, 도 4는 도 3의 탄소섬유를 이용한 안전로프의 다른 예 확대 단면도이다.FIG. 3 is a perspective view showing a part of another example of the safety rope using carbon fiber according to the present invention, and FIG. 4 is an enlarged cross-sectional view of another example of the safety rope using the carbon fiber of FIG.

도 3,4의 본 발명에 따른 탄소섬유를 이용한 안전로프의 다른 예는, 지름이 작은 탄소섬유(10)를 다수 개 꼬아서 형성되는 심재(20)와, 상기 심재 수개를 꼬아서 형성되는 로프부재(30)를 유기바인더에 담가서 침투시키고 건져서 건조하여 수개의 심재들이 한 몸체로 되게 부착하는 것은 상기 도 1,2의 일 예와 동일하며, 다만, 상기 유기바인더를 침투시켜 건조한 로프부재 수개가 일정간격의 1열로 배열매입되게 압출기로 우레탄을 압출하여 피복되도록 함으로써 안전로프가 벨트형태로 형성되게 하는 것을 특징으로 한다.Another example of the safety rope using the carbon fiber according to the present invention shown in Figs. 3 and 4 is a rope comprising a core 20 formed by twisting a plurality of carbon fibers 10 having a small diameter, The member 30 is immersed in an organic binder, dried, and dried so that several core members are attached as one body. However, the number of the dried rope members penetrated the organic binder, The urethane is extruded and extruded by an extruder so as to be embedded in one row at regular intervals so that the safety rope is formed into a belt shape.

이렇게 벨트형태로 형성되는 안전로프는, 일 예로 무거운 중량물을 들어 옮기는 크레인이나 승강기 등에서의 호이스트의 로프로 사용될 수 있다.The safety rope thus formed in the form of a belt can be used, for example, as a hoist rope in a crane or an elevator for carrying heavy heavy objects.

이와 같은 본 발명에 따른 탄소섬유를 이용한 안전로프는, 탄소섬유(10)를 꼬아서 되는 심재(20)와, 상기 심재를 꼬아서 되는 로프부재(30)의 외면에 인장 강도가 높고 난연성과 유연성 및 내마모성을 갖는 우레탄을 소정두께로 피복하여 되는 외피부(40)로 구성되는 것이므로, 섬유나 합성수지 또는 강선을 사용하여 제조한 로프에 비하여 지름이 작고 가벼우면서도 인장 강도가 높고 내열성과 난연성임은 물론 유연성과 내마모성 및 내화학약품성 등이 우수하여 화재나 고온의 환경에 장시간 노출되거나 고온의 마찰열이 발생하여도 인장 강도가 유지됨과 동시에 물성이 변하지 않아 장기간 안심하고 사용할 수 있으며, 유지관리도 매우 간편·용이하게 되는 등의 특징이 있다.The safety rope using the carbon fiber according to the present invention is characterized in that the core rope 20 in which the carbon fiber 10 is twisted and the rope member 30 in which the core material is twisted have high tensile strength, And the outer skin 40 which is coated with a urethane having a wear resistance to a predetermined thickness. Therefore, the rope of the present invention is small in diameter, light in weight, high in tensile strength, heat-resistant and flame-retardant as compared with a rope made of fiber, synthetic resin or steel wire It has excellent flexibility, abrasion resistance and chemical resistance, so it can maintain tensile strength even if it is exposed to fire or high temperature environment for a long time or generate high temperature frictional heat. And the like.
