The invention relates to the technical field of article transfer tool equipment in a radiation environment, and solves the technical problem that a lifting appliance cannot stably work in radiation and electromagnetic interference environments in the prior art. A round opening and closing self-weight lifting appliance comprises a shell, a driving mechanism is arranged at the upper end of the shell, a ratchet wheel clamping jaw is arranged at the lower end of the shell, and the driving mechanism drives the ratchet wheel clamping jaw to reciprocate in the diameter direction of an inscribed circle of the shell; the driving mechanism comprises a self-weight driver and a power converter, and the self-weight driver drives the ratchet wheel clamping jaw to move through the power converter. The ratchet wheel clamping jaw is opened or contracted in a pure mechanical transmission mode so as to lock or loosen an object to be lifted, and the lifting appliance disclosed by the invention is not provided with electronic elements and can stably work in radiation and electromagnetic interference environments.

    本发明涉及辐射环境中物品转运工具设备技术领域,解决了现有技术中吊具无法在辐射以及电磁干扰环境下稳定工作的技术问题。一种圆形开合自重吊具,包括外壳,所述外壳的上端设置有驱动机构,所述外壳的下端设置有棘轮卡爪,所述驱动机构驱动所述棘轮卡爪沿所述外壳的内接圆直径方向往复运动;所述驱动机构包括自重驱动器和动力转换器,所述自重驱动器通过动力转换器驱动所述棘轮卡爪位移。采用纯机械传动的方式使棘轮卡爪张开或收缩,以锁紧或松开待起吊物品,本发明公开的吊具没有电子元件,可以在辐射、电磁干扰环境下稳定工作。
