The embodiment of the invention relates to the technical field of lifting mechanisms, and discloses an anti-falling assembly and a lifting device.The anti-falling assembly comprises a sliding plate, a connecting piece, a power assisting mechanism and a power assisting mechanism; the sliding plate is in limiting connection with the stand column in the first direction. The connecting piece abuts against the sliding plate and is used for being connected with a lifting rope, so that the lifting rope can drive the sliding plate to ascend and descend in the second direction through the connecting piece; the power assisting mechanism is arranged between the connecting piece and the sliding plate and used for driving the connecting piece to descend relative to the sliding plate in the second direction when the lifting rope breaks down; the locking mechanism is arranged on the sliding plate and comprises a transmission structure and a locking block; the transmission structure is used for being driven by the connecting piece to drive the locking block to move towards the stand column when the connecting piece descends relative to the sliding plate in the second direction, so that the locking block abuts against the surface of the stand column, and the sliding plate stops descending. According to the embodiment, when the lifting rope breaks down, the sliding plate can stop falling and is fixed to the stand column, and safety accidents are avoided.
本申请实施例涉及升降机构技术领域,公开了一种防坠落组件及升降装置,该防坠落组件包括滑板、连接件、助力机构和所及机构;滑板沿第一方向与立柱限位连接;连接件与滑板相抵接,并用于与升降绳连接,使得升降绳可通过连接件带动滑板沿第二方向升降移动;助力机构设置于连接件和滑板之间,助力机构用于在升降绳发生故障时驱动连接件相对于滑板沿第二方向下降;锁紧机构设置于滑板上,包括传动结构和锁紧块;传动结构用于在连接件相对于滑板沿第二方向下降移动时,受连接件的驱动进而带动锁紧块朝向立柱运动,以将锁紧块抵接于立柱表面,使滑板停止下降。本申请实施例可以升降绳发生故障时,滑板会停止坠落并固定于立柱上,以免引发安全事故。
