Translation type movable box overturning and material dumping device

The invention relates to a translation type movable box overturning and material dumping device. The translation type box overturning and material dumping device comprises a trolley (1) which travels between a skyrail (12) and a ground rail (13) and can reciprocate along the rails, a lifting table (2) which is arranged between two uprights (3) at two sides of the trolley and can move up and down along the uprights (3), a fork device (4) which is arranged on the lifting table (2) and can horizontally extend and retract in perpendicular to the traveling direction of the trolley, and a box overturning and material dumping device (5) which is arranged at the bottom of the fork device (4) and can be overturned. According to the translation type movable box overturning and material dumping device provided by the invention, the box overturning radius is small, the working process is stable and reliable, multiple functions can be realized, the equipment investment cost is saved, the materials are prevented from being scattered to the outside of the boxcar in moving and overturning processes at the same time, and the production cost can be reduced.
