The invention belongs to the technical field of workpiece storage and transportation, and discloses an anti-falling mechanism and a hoister, the anti-falling mechanism comprises a rack, a mounting seat, a tooth block and an elastic piece, and the rack is vertically arranged; a first guide structure which is inclined downwards from one end far away from the rack to one end close to the rack is arranged on the mounting seat; the tooth block is in guide connection with the first guide structure through the second guide structure; when the second guide structure is located at the lowest end of the first guide structure, the tooth block is meshed with the rack, and when the second guide structure is located at the highest end of the first guide structure, the tooth block is separated from the rack; the elastic piece is connected to the tooth block and the installation base so that the second guide structure can keep the trend of moving towards the lowest end of the first guide structure. The elevator comprises the anti-falling mechanism, and the arrangement of the anti-falling mechanism in the elevator reduces the possibility of rapid falling of the lifting basket, so that the lifting basket and a workpiece can be prevented from being damaged.
本发明属于工件仓储运输技术领域,公开了一种防坠机构及提升机,防坠机构包括齿条、安装座、齿块和弹性件,齿条竖直设置;安装座上设置有自远离齿条的一端向靠近齿条的一端倾斜向下的第一导向结构;齿块通过第二导向结构与第一导向结构导向连接;第二导向结构位于第一导向结构的最低端时,齿块与齿条啮合,第二导向结构位于第一导向结构的最高端时,齿块与齿条分离;弹性件连接于齿块和安装座,以使第二导向结构保持向第一导向结构的最低端移动的趋势。提升机包括上述防坠机构,提升机中防坠机构的设置降低了提篮急速坠落的可能,有利于避免提篮和工件损坏。
