The invention discloses a lifting device of an anti-falling structure for constructional engineering. The lifting device of the anti-falling structure for constructional engineering comprises a supporting device and a lifting mechanism; the lifting mechanism is installed at the upper end of the supporting device; when a second driving motor rotates to drive a steel cable to ascend and descend, a rotating disc drives a rotating head to rotate together; when the second driving motor fails and the power of the second driving motor fails, a weight at the lower end of the steel cable drives the rotating disc to start to rotate quickly, and the rotating disc drives the rotating head to rotate quickly; when the rotating head rotates quickly, a self-locking head mounted at the upper end of the rotating head starts to move upwards under the action of centrifugal force, and a first limiting tooth can be engaged with a ratchet tooth to stop the rotation of the rotating head; sliding blocks are installed at the two ends of the self-locking head; when the sliding blocks move upwards in an inner cavity of the sliding groove, the sliding blocks can enable the limiting blocks to retract; after thelimiting blocks retract, the limiting blocks can be clamped at the lower ends of the sliding blocks, so that movement of the self-locking head can be locked, and the hoisted object is further prevented from falling to injure people.

    本发明公开了一种建筑工程用防掉落结构的起吊装置,包括支撑装置和起吊机构,支撑装置的上端安装有起吊机构,当第二驱动电机转动带动钢索进行升降移动时,旋转盘带动旋转头一同进行旋转,第二驱动电机出现故障导致第二驱动电机动力失效,钢索下端的重物带动旋转盘开始快速转动,旋转盘则带动旋转头快速转动,旋转头快速转动时,旋转头上端安装的自锁头在离心力的作用下开始向上移动,第一限位齿能够与棘齿相互卡合,从而能够使旋转头停止旋转,自锁头的两端安装有滑块,滑块在滑槽内腔向上移动时,滑块能够使限位块回缩,限位块回缩后,能够使限位块卡在滑块的下端,从而能够锁止自锁头的移动,进一步的防止起吊物下落砸伤人。
