Zusammenfassung: | The present invention relates to an automatic opening and closing device for a manhole lid. The present invention solves problems, wherein a manhole lid is not easily opened or closed as foreign substances such as dust are hardened between circumferential surfaces of the manhole lid inserted into an upper end of a manhole support frame, the outer surface of the manhole lid is cracked or damaged when a bar such as a pipe is inserted into a groove of the manhole lid to lift up the manhole lid by a lever principle, efficiency of opening and closing work is decreased as the load of the manhole lid is heavy, and a worker stubs toes during the opening and closing work. The automatic opening and closing device for a lid comprises a moving table (100), a manhole lid detaching device (200), and a smart device (300). The automatic opening and closing device for a manhole lid receives the position of a manhole from a manhole management server in a remote place and transmits position data about the manhole to the foldable moving table. The automatic opening and closing device for a manhole lid can control general operation of the automatic opening and closing device for a manhole lid and the foldable moving table through a local area network. The automatic opening and closing device for a manhole lid facilitates attachment and detachment by removing foreign substances hardened between the circumferential surfaces of the manhole lid inserted into the upper end of the manhole support frame. The automatic opening and closing device for a manhole lid prevents the outer surface of the manhole lid from being damaged by enabling the worker to safely and automatically open and close the manhole lid using a magnetic force of an electromagnet without devoting energies of the worker. The automatic opening and closing device for a manhole lid using the electromagnet can improve work environment and facilitates the manhole lid opening and closing work.
본 발명에서는 맨홀 받침틀의 상단부에 삽입되어 있는 맨홀 뚜껑의 둘레면 사이에 먼지 등의 이물질이 시간이 지남에 따라 단단히 굳어져 맨홀 뚜껑의 개폐가 용이하지 않고, 파이프와 같은 막대를 맨홀 뚜껑의 홈에 삽입하여 지렛대의 원리로 들어올릴 경우 외부 표면에 흠집이 발생하거나 파손되고, 맨홀 뚜껑 자체의 하중이 커 개폐작업의 효율이 떨어지고, 개폐중 작업자의 발을 찧는 등의 안전상의 위험이 따르는 문제점을 개선하고자, 이동 테이블(100), 맨홀 뚜껑 탈착장치(200), 스마트 디바이스(300)로 이루어진 맨홀뚜껑 개폐장치가 구성됨으로써, 원격지의 맨홀관리서버로부터 맨홀의 위치를 수신받아, 접이식 이동 테이블쪽으로 맨홀의 위치데이터를 전송시키고, 근거리통신망을 통해 접이식 이동 테이블과 맨홀 뚜껑 탈착장치의 전반적인 구동을 제어시킬 수 있고, 맨홀 받침틀의 상단부에 삽입되어 있는 맨홀 뚜껑의 둘레면 사이에 굳어진 이물질을 제거하여 탈결합이 용이하게 하고, 작업자가 힘을 들이지 않고 전자석의 자기력을 이용하여 자동으로 안전하게 맨홀뚜껑을 개폐할 수 있 |
