Sinking platform for concreting vertical shaft

The utility model relates to a sinking platform for concreting a vertical shaft, which comprises an upper layer platform which has one to two layers and a lower layer platform, and is characterized in that: the lower layer platform can lift relative to the upper layer platform; and the lower layer platform comprises a panel, a wire rope and a miniature hoister; and the panel is hung below the upper layer platform through the wire rope by the miniature hoister. Compared with the prior art, the sinking platform for concreting the vertical shaft has the advantages that: a concreting operating platform which has simple structure, is easy to operate, and has high operating efficiency and good safety performance is provided for a user, so as to greatly shorten the assembling and disassembling time of the conventional operating platform; the lifting range of the lower layer platform is as high as 30m; the sinking platform does not need to be repeatedly lifted, so as to save the lifting and fixing time of the sinking platform and eliminate the potential safety hazard brought by the sinking platform. The sinking platform for concreting the vertical shaft is applicable to concreting construction of the vertical shaft, in particular to horsehead construction.
