A moving wheel 12 is provided at the bottom of the support plate 11. A baffle 13 for fixing the bottom of the ash hopper 2 is also provided on the outside of the two support plates 11. When the two support plates 11 are turned to the outside of the ash hopper 2, the baffle 13 can provide support for the support plates 11. It should be noted that at this time, the two support plates 11 are in an eight-shaped shape, and the moving wheel 12 is in a vertical state at this time;

[0021] A fixing block 14 is provided on each of the two support plates 11 , a through slot 15 is provided on each of the fixing blocks 14 , and a blocking rod 16 penetrating the two through slots 15 is inserted on the two support plates 11 . When the through slots 15 on the two support plates 11 are coaxial, the blocking rod 16 can penetrate the two through slots 15 , thereby limiting the two support plates 11 .

[0022] Embodiment 2: A gantry ash hopper for pouring prefabricated box girder concrete comprises an ash hopper 2 provided with a feed port 1, which is convenient for feeding concrete into the ash hopper 2 through the feed port 1, and the upper side of the ash hopper 2 is connected with a hanging hole 4 provided on the ash hopper 2 through four evenly distributed connecting rods 3. Through the setting of the hanging hole 4, the ash hopper 2 is lifted on the gantry frame, which is convenient for pouring the box girder skeleton;

[0023] A driving mechanism is provided on the ash hopper 2, and a driving end of the driving mechanism is connected to a vertically arranged transmission column 5.

[0028] Working principle:

[0029] 1. After the ash hopper 2 is lifted by the gantry, concrete is put into the ash hopper 2 through the feed port 1, and then the ash hopper 2 is driven to move by the gantry so that the ash hopper 2 can distribute the material to the box beam frame. After the valve 8 is opened, the concrete can fall on the box beam frame through the discharge pipe 7. When the material is almost discharged from the ash hopper 2, the motor 10 is turned on. The motor 10 can drive the spiral blade 6 to rotate through the transmission column 5, so as to push the concrete remaining on the inner wall of the ash hopper 2 to the bottom of the ash hopper 2, so as to facilitate the cleaning of the ash hopper 2;

[0030] 2. After the concrete is discharged, the ash hopper 2 is moved to an open space through the gantry, and then the blocking rod 16 is pulled out, so that the two support plates 11 are rotated to the outside of the ash hopper 2, so that the two ash hoppers 2 are in an eight-shaped shape. The blocking rod 16 can block the support plate 11 so that the support plate 11 can provide support for the ash hopper 2. The ash hopper 2 is conveniently moved by setting the moving wheel 12.
