The invention belongs to the technical field of elevator protection, and particularly relates to an elevator falling protection device and a protection method. The elevator falling protection device comprises an elevator shaft and an elevator car arranged in the elevator shaft; the elevator falling protection device further comprises a pressure bearing plate, a buffering spring, an energy consumption device and a buffering device; the pressure bearing plate is located under the elevator car and is connected to the bottom of the elevator shaft through the buffering spring; the energy consumption device which is used for achieving the buffering and continuous friction energy consumption effects on the elevator car in the elevator falling process is connected between the side wall of the pressure bearing plate and the side wall of the elevator shaft; and the bottom of the pressure bearing plate and the bottom of the elevator shaft are connected with the buffering device which is used for effectively buffering and protecting the elevator car while ensuring that the pressure bearing plate does not incline in the elevator falling process. According to the elevator falling protection device and the protection method, the elevator car after falling is effectively buffered and protected while it is guaranteed that the elevator does not incline, and therefore the safety of passengers in the elevator car is improved.
本发明属于电梯防护技术领域,具体涉及一种电梯坠落保护装置以及保护方法。本发明包括电梯井和设置在电梯井内的电梯轿厢;还包括承压板、缓冲弹簧、耗能装置和缓冲装置;承压板位于电梯轿厢的正下方,承压板通过缓冲弹簧连接于电梯井的底部;承压板的侧壁与电梯井的侧壁之间连接有用于在电梯坠落过程中对电梯轿厢起到缓冲以及持续摩擦耗能作用的耗能装置;承压板底部与电梯井的底部连接有用于电梯坠落过程中保证承压板不会倾斜的同时对电梯轿厢进行有效缓冲与保护的缓冲装置。本发明在保证电梯不会倾斜的同时对坠落后的电梯轿厢进行有效缓冲与保护,从而提高电梯轿厢内乘客的安全性。
