The invention relates to the technical field of elevators, and discloses an elevator shaft falling object protection device which comprises a gantry frame, an anti-falling net, a front guide rope, a falling block body, an electromagnet, an angle displacement sensor and a single-chip microcomputer controller. The side fixing plates and the main fixing plate are attached to the inner wall of an elevator shaft and fixed in the elevator shaft through bolts, side slideways are arranged on the gantry frame in a bilateral symmetry mode, guide holes are formed in the front end of the gantry frame and communicated with the side slideways, and an elastic net storage cavity is further formed in the gantry frame. When the angular displacement sensor detects an abnormal angular displacement signal, the single-chip microcomputer controller obtains a trigger signal and then powers off the electromagnet; and after the electromagnet is powered off, the electromagnet loses magnetism, so that the falling block body falls under the action of gravitational potential energy, and the sliding clamping block is pulled to move forwards, so that the nylon protective net is unfolded.

    本发明涉及电梯技术领域,公开了一种电梯井道坠物保护装置,本发明包括龙门框、防坠网、前导绳、坠块体、电磁铁、角度位移传感器、单片机控制器,所述龙门框上焊接固定设有侧固定板和主固定板,所述侧固定板和所述主固定板贴合在电梯井道的内壁并通过螺栓固定在电梯井道内,所述龙门框上左右对称设有侧滑道,所述龙门框的前端与所述侧滑道连通设有引导孔,所述龙门框内还设有弹网储腔。本发明通过当所述角度位移传感器探测到异常角位移信号时所述单片机控制器得到触发信号后对所述电磁铁断电,所述电磁铁断电后失磁导致所述坠块体在重力势能作用下下坠从而拉动所述滑动卡块向前移动使得所述尼龙防护网展开。
