The invention discloses a buffer device for a lift car of an elevator shaft. The buffer device comprises speed reducing mechanisms movably connected with the side wall of the elevator shaft and the side wall of the lift car, a first buffer mechanism positioned under the lift car and fixedly connected with the bottom of the elevator shaft, and second buffer mechanisms positioned on the left side and the right side of the first buffer mechanism and corresponding to the first buffer mechanism, wherein the number of the speed reducing mechanisms and the second buffer mechanism are each two. The two speed reducing mechanisms are positioned on the left side surface and the right side surface of the lift car, and the two second buffer mechanisms are symmetrically arranged on the left side and theright side of the first buffer mechanism respectively. Through the arrangement of the speed reducing mechanism, the elevator falling speed is reduced, and therefore a better buffering effect is achieved on elevator falling; and through the arrangement of the first buffer mechanism and the second buffer mechanisms, impact damage to passengers caused by large resilience force generated by the buffer device under impact force is prevented.

    本发明公开了一种电梯井轿厢缓冲装置,包括与电梯井的侧壁和轿厢的侧壁活动连接的减速机构、位于轿厢的正下方且与电梯井的底部固定连接的第一缓冲机构、位于第一缓冲机构的左右两侧且与第一缓冲机构相对应的第二缓冲机构,减速机构和第二缓冲机构均设置两个,两个减速机构分为位于轿厢的左侧面和右侧面,两个第二缓冲机构分别在第一缓冲机构的左右两侧对称设置,本发明减速机构的设置,减小电梯坠落的速度,从而对电梯坠落起到更好的缓冲作用,第一缓冲机构和第二缓冲机构的设置,防止缓冲装置受冲击力后产生较大回弹力对乘客造成冲击伤害。
