The invention provides a locking device of a lifting hook and a lifting appliance. The locking device of the lifting hook comprises a base, a locking assembly and an angle adjusting assembly. The base is fixedly connected with a transverse beam of the lifting hook; the locking assembly comprising a locking part, and one end of the locking part is movably connected with the base so that the locking part can be located at the locking position or the non-locking position; and the angle adjusting assembly comprises a body and at least one notch, the body is provided with a through hole so as to be connected with the lifting hook, and the notch is formed in the body. When the locking part is moved to the other end of the locking part so as to be clamped into one notch, the locking part is located at the locking position, and the lifting hook is locked and cannot rotate around the axis of the lifting hook; and when the locking part is moved to the other end of the locking part so as to be separated from the notches, the locking part is located at the non-locking position, and the lifting hook can rotate. The locking device of the lifting hook can ensure that when the lifting hook does work, the direction of the lifting hook is fixed, rotation at will is avoided, and smooth implementation of production is guaranteed.
