技術說明

一種大氣壓力的電梯升降裝置包括，一伸縮汽缸、一承載架、一抽氣機、以及一氣路控制器所組合，其中伸縮汽缸是一種有伸縮體積的腔體，該腔體一端懸吊一承載架，另一端是固定，腔體連接一氣路控制器，該氣路控制器由固定氣筒、氣閥、以及抽氣機組合；當承載架要上升時，經由氣路控制器讓抽氣機針對伸縮汽缸進行抽氣，該伸縮汽缸內的壓力逐漸降低，則伸縮汽缸受大氣壓力也逐漸增加至超過承載的重量時，承載架上升，伸縮汽缸將縮小至最頂端，然後控制氣閥讓伸縮汽缸保持低壓狀態；當承載架要下降時，經由氣路控制器讓伸縮汽缸逐漸進入定量的空氣，則伸縮汽缸受大氣壓力也逐漸減少而下降為其特徵者。 A pneumatic vertical transportation device comprises an expandable cylinder, a carriage rack, an air piping controller, and an air exhauster. The expandable cylinder includes a bellow body, with one end hanging carriage rack and the other end connected with a fixing plate. The expandable cylinder is connected with the air piping controller. While the carriage rack is to rise, the air exhauster draws air from the bellow body through the air piping controller to gradually decrease pressure inside. Once pressure difference exceeds weight of the carriage rack, the carriage rack begins to rise. Volume of the expandable cylinder is reduced such that the lower disc of the expandable cylinder approaches top, and the expandable cylinder is maintained at low pressure state. While the carriage rack is to descend, air is fed into the expandable cylinder through the air piping controller to gradually expand the bellow body and let the carriage rack descend.
