The invention discloses a protection device for a vertical shaft expanding excavation construction operation platform, which comprises a base, four corners of the base are provided with grooves I, one side of each groove I is longitudinally provided with a support rod, the other end of each support rod is provided with a top net, the top end of the top net is provided with a protection plate, and the top of the protection plate is fixedly connected with a hook. Four first grooves corresponding to the supporting rods are formed in the top net, four second grooves corresponding to the supporting rods are formed in the top net, clamping assemblies are arranged in the first grooves and the second grooves in a clamped mode, the clamping assemblies are fixedly connected with the two ends of the corresponding supporting rods respectively, a side net is arranged between every two adjacent supporting rods, and fixing assemblies used for limiting the side plates in the vertical direction are arranged between the side nets and the supporting rods. The anti-falling block has the advantages that the anti-falling block is reasonable in structure, and the problems of injury to users due to falling blocks and difficulty in disassembly and assembly can be solved by the aid of the anti-falling block.
