The invention discloses an anti-falling device of a spraying line workpiece lifter. The anti-falling device solves the problem of how to prevent a workpiece from falling when a lifting chain is broken. An L-shaped swing arm (25) mechanism and a locking hook swing arm (23) mechanism are respectively arranged on the lifting cantilever beam (2); when a chain is broken, upward traction force on an L-shaped swing arm (25) disappears, the L-shaped swing arm (25) rotates anticlockwise under the action of an L-shaped swing arm left push spring (13), a steel wire rope (16) moves leftwards, the rightward traction force of the steel wire rope (16) on a locking hook swing arm (23) is reduced, the locking hook swing arm (23) rotates anticlockwise under the action of a locking hook swing arm left push spring (24), and the locking hook swing arm (23) is locked. A locking sawtooth block (20) is inserted into a locking sawtooth block embedding groove (22) in a long strip plate (21), and the lifting cantilever beam (2) is locked, so that the lifting cantilever beam (2) cannot fall off; and the safety of ground operation workers is ensured.

    本发明公开了一种喷涂线工件升降机的防坠落装置,解决了当提升链条发生断裂时如何防止工件坠落的问题;在升降悬臂梁(2)上分别设置有L形摆臂(25)机构和锁紧钩摆臂(23)机构;当链条发生断裂时,对L形摆臂(25)的向上牵引力消失,L形摆臂(25)在L形摆臂左推弹簧(13)的作用下逆时针旋转,使钢丝绳(16)向左移动,导致钢丝绳(16)对锁紧钩摆臂(23)向右的牵引力变小,锁紧钩摆臂(23)在锁紧钩摆臂左推弹簧(24)的作用下逆时针旋转,将锁紧锯齿块(20)插入到长条板(21)上的锁紧锯齿块嵌入凹槽(22)中,将升降悬臂梁(2)锁定,使其不会发生坠落;保证了地面操作工人的安全。
