The invention relates to the field of elevators, in particular to an elevator with a falling buffering function, which comprises an exoskeleton frame, an electric cabin door, pulleys and the like, an electric cabin door is mounted on the exoskeleton frame, and an acceleration sensor is arranged on the exoskeleton frame; the exoskeleton frame is provided with two pulleys. The high-strength exoskeleton frame is arranged and used for protecting the lift car from deformation when emergency falling happens, safety of passengers in the lift car is protected, the electromagnet and the annular permanent magnet are arranged between the lift car and the exoskeleton frame, falling of an elevator is buffered through the electromagnetic damping effect, and the safety of the elevator is improved. The situation that after the exoskeleton frame makes contact with the hydraulic buffering device, the exoskeleton frame rebounds, and consequently the lift car bounces up and down is reduced, stable stopping of the lift car is achieved, and the situation that the lift car bounces rapidly, and secondary damage is caused to passengers in the lift car is avoided.
本发明涉及升降电梯领域,尤其涉及一种具有坠落缓冲的升降电梯,包括有外骨骼框架、电动舱门和滑轮等;外骨骼框架安装有电动舱门,外骨骼框架上设有加速度传感器;外骨骼框架安装有两个滑轮。通过设置高强度的外骨骼框架,用于保护轿厢在发生紧急坠落时,不会发生形变,保护轿厢内乘客的安全,并且在轿厢与外骨骼框架之间设置电磁铁和环形永磁体,通过电磁阻尼效应,对电梯的坠落进行缓冲,减少外骨骼框架接触到液压缓冲装置后,外骨骼框架出现反弹,以至于轿厢出现上下弹跳的情况,实现轿厢平稳停下,避免轿厢快速弹跳起来,对轿厢内的乘客造成二次伤害。
