화물적재함 덮개의 개폐장치{The opening and shutting equipment of a cargo on board case cover}The opening and shutting equipment of a cargo on board case cover}

본 고안은 화물차의 적재함을 덮어주는 덮개에 관한 것으로, 특히 2단으로 구성되는 덮개가 개폐작동시 정확하고 안전한 상태로 절첩 전개되도록 캠(Cam)을 구비하는 제1작동암과 상기의 작동암과 로드(Rod)로 연결되는 제2작동암이 구동축의 정역구동에 따라 이에 고정된 지지바의 작동으로 제1덮개부와 제2덮개부가 적재함으로 개폐되어지게 한 구성의 화물적재함 덮개의 개폐장치에 관한 것이다.The present invention relates to a cover for covering a loading box of a freight car, and in particular, a cover consisting of two stages has a first operating arm and a cam (Cam) to be folded and deployed in an accurate and safe state during opening and closing operation. The second operating arm connected to the rod is connected to the opening and closing device of the cargo loading cover of the configuration in which the first cover part and the second cover part are opened and closed by the operation of the support bar fixed thereto according to the forward and reverse driving of the drive shaft. It is about.

화물적재함의 덮개장치는 종래에도 다양한 구조를 가지는 것들이 등장된 바 있다.The cover device of the cargo container has been introduced to those having various structures in the past.

그 중에서도 근간에 실용신안공보에 게재된 "화물적재함 덮개의 덮개절첩구조"(등록실용신안 제208386호)는 제1덮개부와 제2덮개부로 구성되고 상기 제2덮개부가 제2덮개 절첩수단과 스프링에 의해 접어지는 화물차 적재함 덮개에 있어서, 상기 제2덮개부의 덮개틀에 코일스프링이 감기도록 장착되고, 상기 코일스프링의 한쪽 절곡부는 제2덮개부의 지지대에 걸려지며 다른 쪽 절곡부는 제1덮개부와 바에 걸려 제2덮개부의 안쪽으로 당김으로서, 덮개가 절첩될 수 있게 한 것인데, 이는 종래 인장스프링을 사용한 화물적재함 덮개에 비해 그 기술수단이 크게 향상된 것이라고 보여지지 않이할 뿐만 아니라 인장스프링을 코일스프링으로 대체하여 복원력을 높이한다는 기술적 효과에 있어서도 단순히 종래의 인장스프링을 코일스프링으로 대체한 것에 불과하고, 특히 코일스프링이나 인장스프링 및 기타 다양한 종류의 스프링들은 그 어느 것이나 탄발력과 복원력을 가지고 있기는 하지만 점차 수명을 오래할 수록 신축작용이 크게 떨어지기 때문에 이것을 매체로 한 구조물들의 기능이 제대로 발휘되지 못하는 문제점이 있어 왔으므로 어느 시점에 도달하게 되면 스프링을 교체하여 주어야 하는데 따른 경제적인 어려움과 교체작업의 번거러움도 수반할 뿐만 아니라 제1덮개부를 감싸고 있는 덮개틀이 적재함의 측벽과 약간 벌어진 상태로 설치되어짐에 따라 운행중 적재물이 그 사이를 통해 흘러내리는 폐단도 있어 왔다.Among them, the "cover folding structure of the cargo container cover" (registered utility model No. 208386) published in the Utility Model Publication in recent years is composed of a first cover portion and a second cover portion, and the second cover portion includes a second cover folding means.

Even in the technical effect of increasing the restoring force by replacing the spring, it is simply replacing the conventional tension spring with the coil spring. In particular, coil springs, tension springs, and various other types of springs have resilience and resilience, but their elasticity decreases as their lifespan increases over time, so the structures using these mediums function properly. Since there has been a problem that can not be reached at some point, the economical and cumbersome replacement of the spring must be replaced, and the cover frame surrounding the first cover part is slightly open with the side wall of the loading box. As installed, there have been closures where loads flow down between them during operation.
