[0045] The lifting assembly 7 comprises a third telescopic cylinder 71 fixedly installed on the moving frame 53, the output shaft of the third telescopic cylinder 71 is fixedly installed with a lifting plate 72 in sliding connection with the moving frame 53, the bottom of the lifting plate 72 is fixedly installed with a connecting rod 73, the connecting rod 73 is provided with a buckling groove 74, the connecting rod 73 is inserted into the connecting groove 35 and in contact with the bottom of the connecting groove 35, at this time, the buckling groove 74 is in communication with the through hole 36, the top block 38 is inserted into the through hole 36 and the buckling groove 74, and the connecting rod 73 is automatically locked on the lifting block 32, so that the output end of the lifting assembly 7 is in power connection with the lifting block 32.

[0046] Working principle: the pouring assembly 3 is inserted on the supporting frame 22 through a lifting vehicle or a crane and the like, the electric rotating table 21 drives the pouring assembly 3 to rotate to a pouring position, the output shaft of the first telescopic cylinder 52 drives the moving frame 53 to move, so that the connecting rod 73 is above the connecting groove 35 and coaxial, at this time, the pushing rod 63 is coaxial with the insertion groove 47.

[0047] The output shaft of the third telescopic cylinder 71 drives the lifting plate 72 and the connecting rod 73 to descend, the connecting rod 73 is inserted into the connecting groove 35 and in contact with the bottom of the connecting groove 35, at this time, the buckling groove 74 is in communication with the through hole 36.

[0048] The output shaft of the second telescopic cylinder 61 drives the top rod 63 to move, and the top rod 63 drives the clamping plate 65 to insert into the insertion slot 47 from the gap between the two groups of arc blocks 48. When the clamping plate 65 moves to the rear side of the arc block 48, the second dial head 55 moves from the horizontal slot to the arc slot and then to another horizontal slot. At this time, the top rod 63 drives the clamping plate 65 to rotate, so that the clamping plate 65 and the arc block 48 are overlapped in the axial direction. The top rod 63 continues to move and pushes the limiting block 41 out of the limiting hole 34. The limiting block 41 compresses the second elastic element 312.
