The invention relates to the technical field of civil engineering, in particular to a movable-type hydraulic work protective platform applied into a tunnel. The movable-type hydraulic work protectiveplatform comprises a flat transporting trolley, a wheeltrack-type hydraulic lifting rack part mounted on a trolley body, a wheeltrack-type hydraulic lifting arching mounting trolley part and a wheeltrack-type hydraulic lifting telescopic protective rack part. The wheeltrack-type hydraulic lifting rack part comprises a wheeltrack-type hydraulic lifting rack which comprises a rack upper part and a rack lower part. The rack lower part is provided with a rack travelling device and supporting legs for supporting the hydraulic lifting rack, and the rack upper part is provided with a lifting device and a foldable working platform. The wheeltrack-type hydraulic lifting arching mounting trolley part comprises a mounting trolley mounted on the trolley working platform. The wheeltrack-type hydrauliclifting telescopic protective rack part comprises a wheeltrack-type hydraulic lifting telescopic protective rack, a protective rack lifting device and a protective rack lifting platform. The movable-type hydraulic work protective platform has the technical advantage that the safety degree of centralized operation is high.
