The invention relates to a lifting hook and a lifting device. The lifting hook is characterized in that a notch for accommodating a to-be-lifted component is formed in a hook seat; the hook body comprises a rotating shaft part, and a triggering part and a closing part which are connected to two opposite ends of the rotating shaft part, and the hook body is rotatably connected with the hook seat through the rotating shaft part; the trigger assembly comprises a locking piece installed on the hook base, and when the trigger part is subjected to trigger force in the second direction, the locking piece relieves locking of rotation of the hook body and exerts force on the trigger part so that the hook body can rotate to the closing part to close the notch. The unhooking driving assembly is arranged on the hook base and can apply force to the closing part so as to drive the hook body to rotate reversely till the notch is opened. According to the scheme, the lifting hook can achieve full-automatic unhooking, the high falling risk caused by manual unhooking during climbing and deep well operation of workers can be eliminated, meanwhile, automatic unhooking can be rapidly and reliably achieved through remote control, and the lifting hook is convenient, rapid and efficient to use.
本发明涉及一种吊钩及吊装装置,包括:钩座形成有用于收容待吊部件的缺口;钩本体包括转轴部及连接于转轴部的相对两端的触发部和闭合部,钩本体通过转轴部与钩座可转动连接;触发组件包括安装在钩座上的锁止件,在触发部受到第二方向的触发力时锁止件解除对钩本体转动的锁止,并对触发部施力使得钩本体转动至闭合部闭合所述缺口;脱钩驱动组件设置于钩座上,脱钩驱动组件能够对闭合部施力以带动钩本体反向转动至将缺口打开。本方案的吊钩能够实现完全自动化脱钩,不仅可消除工人登高和深井作业时手动脱钩时的高坠风险,同时通过远程控制,可快速、可靠的实现自动脱钩,使用方便快捷且高效。
