[0005]

According to the present invention, the movable part at a high place has a mechanical structure without a driving source, so that there is relatively no failure and inspection or refueling can be unnecessary or reduced. The driving force of the movable part is generated from the driving source of the driving part installed on the floor below and on the ground, and the driving force is transmitted to the movable part through the vertical turning pipe to operate the movable part. . In addition, the movable state of the movable part is transmitted to the ground / floor side by the up / down movement of the connecting rod passing through the inside of the rotating pipe, and transmitted to the detection / monitoring device / electric circuit at the ground / floor position. in this way,
The installation of drive sources, detection monitoring devices, and electric circuits, which require high inspection, repair, and refueling, on low ground and floor levels, significantly reduces the labor and labor required for human monitoring, inspection, repair, and refueling. Can be reduced. If the rotating pipe also serves as the supporting member of the movable portion and the driving force transmitting member, the structure becomes simple and the number of failures can be reduced. If a plurality of driving forces are formed into a coaxial multiple pipe structure, the transmission structure can be particularly simplified, the occupied area is reduced, and the transportation and storage of the assembly members are facilitated. In addition, in the case where the outside of the casing of the movable part and the periphery of the mounting table are protected by a flexible waterproof sheet, rainwater, dust, leaves, branches, snow, earth and sand, etc. are prevented from entering the movable part, The failure of the movable part can be greatly reduced. It also prevents the deterioration and deformation of movable parts due to sunlight, light rays and cool air.
