This devise is related to thermal insulation facilities cover opening and closing device, look at the features on the configuration , heating facilities are wound around the one end onto the take-up roller (10) of the lid (1) which is provided so as to open and close to the other end is open is connected to the drive roller 20 by a rope 22, the take-up roller ( 10) is connected to the winding spring 12, the drive roller 20 when closing the cover (1) by pulling the rope 22 winding spring 12 is compressed, to release the rope (22) the cover (1) and characterized in that the cover (1) is provided to take-up by the restoring force of the opening spring when the spring (12). Accordingly, the subject innovation is operated to open and close the take-up roller which air is the drive roller and the cover to operate open and close the lid take-up the slack in a simple synchronization is a constant tension conditions cover by winding spring, in particular for long-term operation with simple structure it is easy to maintain in accordance with the effect.본 고안은 보온시설용 덮개 개폐장치에 관련되며, 구성에 특징을 살펴보면, 보온시설을 개폐하도록 구비되는 덮개(1)의 일단이 권취롤러(10)상에 권취되고, 다른 일단은 로프(22)에 의해 구동롤러(20)상에 연결되어 개폐되며, 상기 권취롤러(10)는 태엽스프링(12)에 연결되어, 구동롤러(20)가 로프(22)를 당겨 덮개(1)를 덮을시 태엽스프링(12)이 압축되고, 로프(22)를 풀어 덮개(1)를 개방시 태엽스프링(12)의 복원력에 의해 덮개(1)가 권취되도록 구비되는 것을 특징으로 한다.이에 따라, 본 고안은 덮개를 개폐작동하는 구동롤러와 덮개가 권취 대기되는 권취롤러가 태엽스프링에 의해 간단하게 동기화되어 덮개가 일정한 장력조건에서 팽팽하게 개폐작동되고, 특히 구조가 간단하여 장기간 운영에 따른 유지관리가 용이한 효과가 있다.
