The invention belongs to the technical field of elevator equipment, and particularly relates to an elevator anti-falling automatic device which comprises anti-falling mechanisms symmetrically arranged at the two ends of a lifting cross beam. The anti-falling mechanism comprises a resettable swing hook arranged on the lifting cross beam; the fixed baffle is fixed to the inner side of the stand column, the movable baffle is rotationally connected to the inner side of the stand column, the movable baffle is located above the fixed baffle, and the movable baffle is arranged on the fixed baffle in a lap joint mode in a natural state; the bottom of the fixed baffle is an upward inclined bevel edge, the top of the movable baffle is a downward inclined bevel edge, and the horizontal length of the movable baffle is larger than that of the fixed baffle. After lifting is completed, the swing hook bypasses the fixed baffle and is clamped into a gap between the fixed baffle and the movable baffle, and therefore the elevator is prevented from falling; and when the lifting is continued, the swinging hook can bypass the rotating movable baffle plate. The elevator cage can be effectively prevented from falling accidentally, and automatic unhooking during falling is achieved.

    本发明属于提升机设备技术领域,具体涉及一种提升机防坠落自动装置,包括防坠落机构,防坠落机构对称设置在升降横梁两端;所述的防坠落机构包括设置在升降横梁上的可复位的摆动挂钩;还包括固定在立柱内侧的固定挡板和转动连接在立柱内侧的活动挡板,活动挡板位于固定挡板上方,处于自然状态时,活动挡板搭放在固定挡板上;固定挡板的底部为一向上倾斜的斜边,活动挡板顶部为一向下倾斜的斜边,活动挡板的水平长度长于固定挡板的水平长度;提升完成后,摆动挂钩绕过固定挡板卡入固定挡板与活动挡板之间的间隙中,从而防止提升机坠落;继续提升时,摆动挂钩可以绕过转动的活动挡板。可以有效防止提升机吊笼意外坠落,并实现下落时自动摘钩。
