The invention discloses a stereotyped operation platform of an elevator shaft. The direction toward a door opening of the elevator shaft is used as the forward direction, and the operation platform comprises a platform panel, a horizontal framework, a supporting framework and at least two lower side supports, wherein the platform panel and the horizontal framework are horizontally arranged and areof rectangular structures matched with the cross section of the inner wall of the elevator shaft, the bottom of the platform panel is welded to the horizontal framework, the bottom of the horizontalframework is welded to the top of the supporting framework, all the lower side supports are fixedly connected to the lower part of the front side of the supporting framework at intervals in the left-right direction, a plurality of round steel hanging rings penetrating through the platform panel are welded to the horizontal framework, and at least two groups of adjustable supporting structures arefixedly connected to the rear side part of the horizontal framework. According to the stereotyped operation platform, the structure is improved on the basis of a traditional elevator shaft operation platform, the lower side supports and the adjustable support structures are added, and the operation platform is ensured to be fixed firmly in the elevator shaft; and moreover, an elevator shaft protection structure is additionally arranged, the construction is safe, the turnover utilization is realized, and the cost is low.
