Movable shield tail grease platform

The utility model relates to the technical field of grease platforms, in particular to a movable shield tail grease platform which comprises a vertical shaft, a placing frame and a shield tunneling machine, ring beams are arranged on the inner wall of the vertical shaft, a pipe piece is arranged at the bottom end of the vertical shaft, a supporting frame is connected to the surface of the pipe piece, and the placing frame is connected to the surface of the supporting frame. The surface of the shield tunneling machine is connected with an extension pipeline, the end, away from the shield tunneling machine, of the extension pipeline is connected with an oil drum, and the oil drum acts on the surface of the containing frame. The movable grease platform is adopted, the problems that injection pressure is lost and injection is not full due to the fact that an extended pipeline is too long when the shield tunneling machine is started in an ultra-deep round well in a large split mode are solved, pressure losses of s
