The invention provides an emergency elevator rescue device, and relates to the technical field of elevator rescue, the emergency elevator rescue device comprises a lift car located in an elevator shaft, friction strips are fixed on the inner wall of the elevator shaft and close to four edges of the lift car, and an anti-falling mechanism is fixed at the bottom of the lift car. The anti-falling mechanism comprises a rotating disc movably installed at the bottom of the lift car, a motor connected with the rotating disc is installed in the lift car, and a motor switch is located at the position of a lift button of the lift car, according to the emergency lift rescue device, when the lift breaks down and starts to fall, internal personnel can press the motor switch to start the anti-falling mechanism, and the motor drives the rotating disc to rotate; the extension rod is driven by the push rod to move towards the friction strip, the gas generator can be started to quickly expand the cylindrical airbag when the fixed barrel abuts against the switch button, the abutting rod can quickly abut against the friction strip to rub with the friction strip, falling potential energy of the lift car is reduced, the damage degree of people inside the lift is reduced, and life safety of the people inside the lift is guaranteed in time.

    本发明提供一种紧急电梯救援装置,涉及电梯救援技术领域,该紧急电梯救援装置,包括位于电梯竖井内的轿厢,所述电梯竖井的内壁且靠近轿厢四条棱处均固定有摩擦条,所述轿厢的底部固定有防坠机构,防坠机构包括活动安装于轿厢底部的旋盘,轿厢的内部安装有与旋盘连接的电机,电机开关位于轿厢的电梯按钮处,该紧急电梯救援装置,电梯发生故障并开始下落时,内部人员可以按动电机开关启动防坠机构,电机带动旋盘旋转,通过推杆带动延伸杆向摩擦条侧移动,固定筒抵触开关按钮时可启动气体发生器将柱形气囊快速膨胀,抵触杆可迅速抵触摩擦条与其摩擦,降低轿厢的下落势能,以降低电梯内部人员的受损程度,及时保证内部人员的生命安全。
