The invention discloses a pneumatic elevator, and relates to the technical field of elevators, the pneumatic elevator comprises a machine base, two lifting guide rails are mounted above the machine base, a lifting seat is slidably mounted between the two lifting guide rails, a synchronous lifting type anti-falling support is mounted above the machine base, and a positioning seat is mounted on the lifting seat; a mechanical transmission mechanism and a mechanical self-locking mechanism are mounted on the positioning seat, a self-locking rod is fixed on the positioning seat, and the mechanical transmission mechanism is in transmission connection with the mechanical self-locking mechanism. When the lifting seat ascends and descends, the mechanical transmission mechanism can drive the mechanical self-locking mechanism to rotate, if the pneumatic elevator falls, the rotating speed of the mechanical self-locking mechanism can be increased instantly, the rotation radius of the gravity center of the mechanical self-locking mechanism can be increased, at the moment, the mechanical self-locking mechanism can be temporarily locked through the self-locking rod, and the mechanical self-locking mechanism can be locked through the self-locking rod. The lifting seat can be temporarily suspended on the synchronous lifting type anti-falling support, so that the lifting seat is prevented from falling, and the anti-falling effect can still be achieved during power failure.
本发明公开了气动提升机,涉及提升机类技术领域,包括机座,机座的上方安装有两处升降导轨,两处升降导轨之间滑动安装有提升座,机座的上方安装有同步升降式防坠支架,提升座的上安装有定位座,定位座上安装有机械式传动机构和机械式自锁机构,定位座上固定有自锁杆,而机械式传动机构与机械式自锁机构之间相互传动连接。本发明的提升座在升降时,通过机械式传动机构能够带动机械式自锁机构自转,若气动提升机发生坠落情况,机械式自锁机构的转速会瞬间增加,导致其重心的自转半径会增加,此时通过自锁杆可将机械式自锁机构暂时锁定,升降座会暂时悬停于同步升降式防坠支架上,以此避免提升座下坠,其在断电时也依然能够实现防坠效果。
