The invention belongs to the field of elevators, particularly relates to an elevator pit protection device capable of preventing personnel from falling off, and aims at solving the problems that when an existing elevator is used, the personal safety of a user cannot be protected through a protection assembly, secondary damage is prone to occurring, the safety coefficient of the device is low, and the protection performance is poor. A through hole is formed in one side of the elevator shaft, two sleeves which are symmetrically arranged slidably penetrate through the interior of the through hole, an infrared sensor is arranged on the inner wall of one side of the elevator shaft, and the infrared sensor is located above the sleeves. When the sleeve is braked, the net bag quickly extends out, personnel are mainly protected from falling from the door of the first floor and absorbing falling energy of the high floor, secondary injury to the personnel due to repeated rebound back and forth is avoided, and the personnel can be protected again due to the arrangement of the safety air bag.

    本发明属于电梯领域,尤其是一种人员防坠落电梯底坑保护装置,针对现有的电梯在使用时,不能通过防护组件对用户的人身安全进行保护,容易出现二次伤害,导致装置安全系数较低,防护性能差的问题,现提出如下方案,其包括电梯井,所述电梯井的一侧设置有通孔,所述通孔的内部滑动贯穿有对称设置的两个套筒,所述电梯井的一侧内壁设置有红外传感器,所述红外传感器位于套筒的上方,本发明中,通过设置红外传感器可以监测到人员掉落,启动电动推杆,解除对套筒的制动状态,网兜快速伸出,主要保护人员从首层层门坠落和吸收高层坠落的能量,避免来回多次反弹,造成人员的二次伤害,同时安全气囊的设置可以再次对人员起到保护作用。
