The invention belongs to the technical field of falling early warning, and particularly relates to a falling alarm device and a lifting platform, the falling alarm device comprises a sliding seat and an edge arm, the sliding seat comprises two transverse rods, and strip-shaped channels are formed in the transverse rods; the winding part comprises a winding shaft matched with the two edge arms in a pivoted mode and a driving mechanism capable of driving the winding shaft to rotate; the detection part comprises a supporting connecting rod, a sleeve and a sensing unit; the two ends of the supporting connecting rod penetrate out of the strip-shaped channels, then are connected with the lifting table body and are provided with elastic arms making contact with the sleeves. A sensitive body on the sensing unit is arranged on the elastic arm; the sensitive body can generate physical quantity change when the elastic arm elastically deforms; one end of the screen cloth is fixed on the sleeve, and the other end of the screen cloth is fixed on the reel and wound on the reel; and the driving mechanism can enable the screen cloth to be wound on the reel and released from the reel in a switching manner. According to the anti-falling device, the anti-falling effect of the lifting platform can be improved, early warning can be given out, it is ensured that operators are rescued in time, and operation safety is improved.
本发明属于坠落预警技术领域,具体涉及坠落报警装置及升降平台,坠落报警装置包括:滑座,包括两根横向杆且在横向杆上形成有条形槽道,以及缘臂;收卷部,包括与两个缘臂枢轴地匹配卷轴及能驱使卷轴旋转的驱动机构;检测部,包括支撑连杆、套管及传感单元;支撑连杆的两端穿出条形槽道后与升降台本体连接且设有与套管接触的弹性臂;在弹性臂上设有传感单元上的敏感体;敏感体能在弹性臂发生弹性变形时产生物理量变化;网布,一端固定在套管上,另一端固定在卷轴上且缠绕在卷轴上;驱动机构能使网布切换地缠绕在卷轴上和由卷轴上释放出来。本发明有助于改善升降台的防坠效果且能发出预警,确保作业人员及时得到救助,提高作业安全性。
