The invention discloses a lifting appliance switching device. The lifting appliance switching device is used for supporting lifting of a conical wall. The lifting appliance switching device comprises a lifting ring assembly, a hook and a pushing piece, wherein the lifting ring assembly is used for connecting a lifting hook; the hook is pivoted in the lifting ring assembly and is used for clamping the flange edge of the supporting conical wall; a first acting surface is arranged on the side of the hook away from the flange; the pushing piece pushes the first acting face and is used for enabling the hook to swing so as to clamp the flange edge of the supporting conical wall. The lifting appliance switching device is inserted into the flange hole of the supporting conical wall, and the pushing piece is used for enabling the hook to swing and clamp the flange edge, so that the lifting appliance switching device can stably and reliably clamp the supporting conical wall, and then the lifting hook of the lifting appliance is used for directly hooking the lifting ring assembly, so that the lifting of the supporting conical wall is realized. The lifting appliance switching device is simple in structure, convenient to use, high in safety and capable of preventing hands from being squeezed by the supporting conical wall and improving the lifting safety of the supporting conical wall.

    本发明公开了一种吊具转接装置,吊具转接装置用于支撑锥壁的吊装;吊具转接装置包括:吊环组件、挂钩、推动件,吊环组件用于连接吊钩;挂钩枢设于吊环组件的内部,挂钩用于卡住支撑锥壁的法兰边;挂钩远离法兰边的侧面设有第一作用面;推动件推动于第一作用面,推动件用于使挂钩摆动,以卡住支撑锥壁的法兰边。通过将吊具转接装置插入支撑锥壁的法兰孔,利用推动件使挂钩摆动并卡住法兰边,从而吊具转接装置能够稳定、可靠地卡住支撑锥壁,再利用吊具的吊钩直接钩住吊环组件,进而实现支撑锥壁降低起吊。吊具转接装置结构简单,使用方便,安全性高,能够避免人手被支撑锥壁挤压,能够提高支撑锥壁吊装的安全性。
