Movable ring rail casting device

The invention discloses a movable ring rail casting device, which is provided a casting ladle (1), wherein the casting ladle (1) is arranged on an annular track (2); the annular track (2) is connected with a frame travelling crane (4) through a connecting frame (3); and the frame travelling crane (4) is arranged on parallel tracks (5). In the invention, the tracks and the frame travelling crane of a hoist can be used. The casting of sand molds at different positions can be satisfied by moving the frame traveling crane on the parallel tracks; and the casting of the sand molds on the same row can be satisfied by moving the casting ladle on the annular track. Due to the adoption of the movable ring rail casting device, a method for casting by manually holding the casting ladle in a floor molding mode is changed, the labor intensity of workers is greatly lowered, and the occurrence of safety accident is reduced. Moreover, the quantity of employees is reduced, and labor cost is lowered. Simultaneously, unstable fa
