The invention discloses a personnel safety sling self-control folding and unfolding anti-falling device, and relates to the technical field of safety protection, the personnel safety sling self-control folding and unfolding anti-falling device comprises a shell, the upper end of the shell is connected with a lifting hook through a shaft, the shell is internally connected with a sling wheel carrier plate through a rotating shaft, the sling is arranged in the middle of the sling wheel carrier plate, and a volute spiral spring assembly is arranged on one side of the sling wheel carrier plate; a non-return mechanism is arranged on the other side of the lifting belt and comprises a descending stopping assembly, a non-return assembly is arranged on the portion, on one side of the descending stopping assembly, of the shell, and the functions of self-control one-way releasing, self-control retracting and safe falling prevention of the lifting belt are achieved through the descending stopping assembly and the non-return assembly. Pure mechanical design is adopted, free switching between a one-way release anti-falling and falling-stopping state and a two-way retraction anti-falling and falling-stopping state can be achieved without operating a device body and pulling a hanging belt, the use requirements in different scenes are met, the operation reliability is improved, and the safety is improved. The safety anti-falling protection device is suitable for occasions needing safety anti-falling protection on personnel such as ship working boats and high-altitude operation, and the safety of the personnel is guaranteed.

    本发明公开了一种人员安全吊带自控收放防坠装置,涉及安全防护技术领域,包括壳体,所述壳体上端通过轴连接有吊钩,所述壳体内通过转轴连接有吊带轮架盘,所述吊带轮架盘中部设置有吊带,一侧设置有涡卷弹簧组件,另一侧设置有止回机构,所述止回机构包括止降组件,所述止降组件一侧的壳体上设置有止回组件,通过止降组件、止回组件实现吊带自控单向释放、自控收回和安全防坠功能。本发明采用纯机械设计,无需操作装置本体,拉动吊带即能在单向释放防坠止降和双向收放防坠止降两个状态之间自由切换,满足了不同场景下的使用要求,提高了操作的可靠性,适用于船舶用工作艇、高空作业等需要对人员进行安全防坠保护的场合,保障了人员安全。
