The invention provides an elevator flexible buffering device, and relates to the technical field of elevator pit buffering, and the elevator flexible buffering device comprises a pit force bearing groove arranged in a pit of an elevator shaft, and an opening of the pit force bearing groove faces upwards; the pit vertical coil is wound outside the side wall of the pit force bearing groove; the car bottom force bearing groove is fixed to the bottom of the lift car, and an opening of the car bottom force bearing groove faces downwards; the compartment bottom vertical coil is wound outside the side wall of the compartment bottom force bearing groove; the bottom pit pressure-bearing spring is arranged in the bottom pit force-bearing groove; the supporting plate is fixed to the top of the pit pressure-bearing spring and used for supporting the compartment bottom force-bearing groove. Under the non-limiting condition, the supporting plate and the pit stress table do not need to make contact with the bottom of the inner side of the car bottom bearing groove, the purpose of non-contact flexible buffering is achieved through electromagnetic force, and the bottom of the car cannot be jacked through; under extreme conditions, the supporting plate and the pit stress table are in contact with the bottom of the inner side of the carriage bottom bearing groove, the supporting plate and the pit pressure bearing spring can also provide upward supporting force, and double insurance is achieved.
本发明提供了一种电梯柔性缓冲装置,涉及电梯底坑缓冲技术领域,其包括:底坑承力槽,设置在电梯井的底坑内,底坑承力槽的开口朝上;底坑垂直线圈,缠绕在底坑承力槽的侧壁外部;厢底承力槽,固定在轿厢的底部,厢底承力槽的开口朝下;厢底垂直线圈,缠绕在厢底承力槽的侧壁外部;底坑承压弹簧,设置在底坑承力槽内;托板,固定在底坑承压弹簧的顶部、用于托举厢底承力槽。非极限情况下,托板和底坑受力台无需接触到厢底承力槽的内侧底部,利用电磁力达到无接触柔性缓冲的目的,不会顶穿轿厢底部;在极端情况下,托板和底坑受力台与厢底承力槽的内侧底部相接触,托板和底坑承压弹簧亦可提供向上的支撑力,实现双重保险。
