A pneumatic elevator system comprises a hoistway, a pneumatic compartment, an air extractor, a switch element and an emergency operation switch, the pneumatic compartment is located in the hoistway, the air extractor is arranged in the hoistway, and when the air extractor is controlled to be started, air is extracted from the space of the hoistway above the pneumatic compartment, so that the pneumatic compartment moves upwards; the switch element is electrically connected with the air extractor, the switch element can be switched on or switched off, the air extractor is started when the switch element is switched on, and the air extractor stops exhausting air when the switch element is switched off; the emergency operation switch is arranged in the pneumatic carriage, electrically connected with the switch element and controlled by a user so that the switch element can be switched on or switched off. Therefore, when a user is trapped in the pneumatic carriage, the user can operate the emergency operation switch for self rescue.
一种气动式电梯系统,包含一井道、一气动车厢、一抽气装置、一开关元件与一紧急操作开关,其中,气动车厢位于井道中,抽气装置设置于井道,抽气装置受控制而启动时,对气动车厢上方的井道的空间抽气,使气动车厢向上移动;开关元件电性连接抽气装置,开关元件可受导通或关闭,开关元件导通时令抽气装置启动,开关元件关闭时,抽气装置停止抽气;紧急操作开关设置于气动车厢中,紧急操作开关电性连接开关元件,紧急操作开关受使用者操控,以令开关元件导通或关闭。借此,使用者受困于气动车厢内部时可操作紧急操作开关进行自救。
