The invention relates to the technical field of freight equipment, and discloses an anti-falling brake device for a freight elevator. The anti-falling brake device comprises an equipment shell and vortex fins, the inner wall of the equipment shell is fixedly connected with a connecting fulcrum shaft, the inner side of the connecting fulcrum shaft is fixedly connected with a limiting clamping ring,and a rotating driving shaft is movably connected to the interior of the limiting clamping ring. According to the anti-falling braking device for the freight elevator, when a lifting platform suddenly descends or suddenly ascends due to a braking fault or other reasons, the rotating speed of the rotating driving shaft is increased at the moment, airflow is driven to ascend through rotation of thevortex fins, and therefore a pneumatic pushing block is pushed to move upwards along the equipment shell. The surface of a piezo-electric crystal is subjected to external force to generate current, amagnet block is pushed rightwards along a movable long groove, a second negative plate is electrically connected to a main braking system of the lifting platform, the lifting platform is controlled to be shut down in time, cargo losses or personnel injuries are prevented, and the safety performance of equipment is improved. Besides, mechanical abrasion is small, and the service life is long.

    本发明涉及货运设备技术领域,且公开了一种货运升降机用防坠制动装置,包括设备壳体和涡流翅片,所述设备壳体内壁固定连接有连接支轴,连接支轴内侧固定连接有限位卡环,限位卡环内部活动连接有转动驱动轴。该货运升降机用防坠制动装置,当升降平台由于制动故障或者其他原因导致其突然下降或者突然上升,此时转动驱动轴转动速度加快,通过涡流翅片转动带动气流上升,从而推动气动推移块沿着设备壳体向上移动,压电晶体表面受到外力产生电流,将磁铁块沿着活动长槽向右推动,第二负极板电性连接至升降平台的总制动系统,控制升降平台及时关停,防止造成货物损失或者人员伤害,提高了设备的安全性能,且机械磨损较小,使用寿命长。
