An active safety buffer strip structure of an elevator comprises a hoistway, a buffer strip is arranged in the hoistway, a plurality of connecting pieces enabling the buffer strip to be kept in the state of being close to the inner wall face of the hoistway are arranged in the hoistway, and a driving unit used for driving the buffer strip to be separated from the connecting pieces and stretch across the middle of the hoistway is arranged on the hoistway. One end of the buffer strip is connected with the hoistway, and the other end is connected with the driving unit; the driving unit is connected with a controller used for controlling the driving unit to work according to the descending speed of the elevator car. When the controller learns that the elevator car descends at an overspeed, the controller starts the driving unit to drive the buffer strip to break away from the connecting piece and stretch across the middle of the hoistway, the elevator car which descends at the overspeed is intercepted and buffered, the effect of buffering in advance is achieved, the descending speed and impact force of the elevator car are effectively reduced, and the service life of the elevator car is prolonged. The buffer strip and the buffer in the shaft pit are combined for buffering and damping, the purpose of double buffering and damping is achieved, and the safety of passengers is guaranteed.

    一种电梯主动安全缓冲带结构,包括井道,所述井道内设有缓冲带,所述井道内设有使缓冲带保持靠向井道内壁面状态的多个连接件,所述井道上设有用于带动缓冲带从连接件脱开并横跨于井道中部的驱动单元,所述缓冲带的一端与井道连接,另一端与驱动单元连接;所述驱动单元连接有用于根据电梯轿厢下降速度控制驱动单元工作的控制器。当控制器获知电梯轿厢超速下降时,控制器启动驱动单元带动缓冲带从连接件上挣脱并横跨于井道的中部,对正在超速下降的电梯轿厢进行拦截缓冲,达到提前缓冲的效果,有效降低电梯轿厢下降的速度和冲击力,让缓冲带与井道底坑内的缓冲器进行组合缓冲减震,实现双重缓冲减震的目的,保证乘客的安全。
