The utility model belongs to the technical field of elevator shaft construction, and particularly relates to a liftable landing leg type elevator shaft construction platform. The liftable supporting leg type elevator shaft construction platform comprises a construction table, a bearing assembly used for supporting the construction table is installed on the front side of the bottom of the construction table, and the bearing assembly comprises two fixing frames; an adjusting assembly used for adjusting the position of the construction table is installed on the outer side of the fixing frame. A driving assembly used for providing power input for the adjusting assembly is installed at the bottom of the construction table. The bearing assembly further comprises two moving frames, buffer blocks are fixedly connected to the two ends of the outer wall of each moving frame, the two fixing frames are arranged on the two sides of the bottom of the construction table correspondingly, and the fixing blocks can be driven by the driving assembly to move in the vertical direction, so that the supporting plate is driven to move up and down through the synergistic effect of the adjusting assembly; and meanwhile, the bearing assemblies work synchronously, and the construction position of the construction table is controlled to be adjusted through movement of the movable frame and the supporting plate.
