The invention provides an upward floating and downward cushion type security elevator and a security method thereof. The upward floating and downward cushion type security elevator includes an elevator room, an elevator shaft, an elevator power mechanism, lift car bodies, speed sensors, first gas storage tanks, connecting pipes, first solenoid valves, buffer devices, a PLC, a control switch, a locking extension box structure, ejector structures and an inflatable buffer box structure. The elevator power mechanism is installed on the lower part of the inner wall of the elevator room in a boltedmode, the lift car bodies are installed in the elevator shaft, and the upper ends of the lift car bodies are connected with the elevator power mechanism. The first gas storage tanks are installed on the middle parts of the front surfaces of the lift car bodies in a bolted mode, one ends of the connecting pipes are in threaded connection with the first gas storage tanks, and the other ends of the connecting pipes are in threaded connection with inflatable cushions. The inflatable buffer box structure and an electromagnetic buffer device are arranged to open a second solenoid valve and inflate an inflatable parachute after the failure of an elevator is detected, so that the inflatable parachute floats in the air, and the function of upward floating and downward buffering protection is realized.
本发明提供上飘下垫式安防电梯及其安防方法,上飘下垫式安防电梯包括电梯房,电梯井,电梯动力机构,厢本体,速度传感器,第一储气罐,连接管,第一电磁阀,缓冲装置,PLC,控制开关,锁紧延伸盒结构,发射器结构和充气缓冲盒结构,电梯动力机构螺栓安装在电梯房内壁的下部,厢本体安装在电梯井内,且上端与电梯动力机构连接,第一储气罐螺栓安装在厢本体前表面的中间部位,连接管一端与第一储气罐螺纹连接,另一端与充气垫螺纹连接。本发明通过充气缓冲盒结构和电磁缓冲装置的设置,当检测到电梯出现故障后,能够使第二电磁阀打开并对充气降落伞充气膨胀,从而让充气降落伞飘浮在空中,实现上飘、下缓冲保护的功能。
