The invention relates to the technical field of hoisting equipment, in particular to a hoisting hook mechanism with an automatic shielding protection function and a crane. The hoisting hook mechanismcomprises a front side plate and a rear side plate, a roller located at the upper part and a hoisting hook located at the lower part are arranged between the two side plates, and movable shielding assemblies and triggering assemblies are arranged on the side faces, away from each other, of the two side plates; each movable shielding assembly comprises a shielding plate and an electric winch, and awinch rope of each electric winch is in traction connection with the corresponding shielding plate; each triggering assembly comprises a guide pipe and a pull rod, a trigger piece is arranged at theupper end of each pull rod, a drag hook is arranged at the lower end of each pull rod, an elastic contraction piece is arranged between each pull rod and the corresponding guide pipe, and a take-up trigger switch and a pay-off trigger switch are arranged on each trigger piece in the up-down stroke; and storage batteries are also arranged on the side plates. According to the hoisting hook mechanism, when an open container is lifted, the open container can be conveniently shielded and protected without extra manual operation.
