The invention relates to the technical field of pneumatic elevators, and discloses a pneumatic elevator which solves the problem that in the using process of a common pneumatic elevator, if the out-of-control phenomenon occurs, people in the elevator can be hurt, and therefore the safety performance is poorer, the air pneumatic elevator comprises a lift car and a guide rail, and speed reduction units are symmetrically installed on the two sides of the lift car; and the speed reduction units are connected with the lift car through symmetrically-arranged air cylinders, a buffering unit is installed at the bottom end of the lift car, the two ends of the buffering unit are connected with the corresponding speed reduction units correspondingly, and a control unit is further installed on the lift car. According to the pneumatic elevator, the control unit, the speed reduction units and the like are used in cooperation, when the lift car is out of control, the speed reduction units can be started through the control unit, the descending speed of the lift car is reduced through the speed reduction units, and therefore the good safety protection effect on personnel in the lift car is achieved.
本发明涉及气压式电梯技术领域,且公开了一种气压式电梯,解决了一般的气压式电梯在使用的过程中,若出现失控现象,会对其内的人员造成伤害,故安全性能较差的问题,其包括轿厢和导轨,轿厢的两侧均对称安装有减速单元,减速单元与轿厢之间通过对称设置的气缸连接,轿厢的底端安装有缓冲单元,缓冲单元的两端分别与对应的减速单元连接,且轿厢上还安装有控制单元;本发明,通过设置的控制单元和减速单元等的配合使用,能够在轿厢发生失控时,通过控制单元启动减速单元,通过减速单元降低轿厢的下降速度,从而对轿厢内的人员起到良好的安全保护作用。
