In implementation, the lifting mechanism includes a lifting movable rod 1, the top of the lifting movable rod 1 is connected to a lifting top plate 2 for placing the limited sand box, the bottom of the lifting movable rod 1 is connected to an active structure for driving the lifting movable rod 1 to move, the lifting movable rod 1 is movably arranged on a positioning plate 3, the positioning plate 3 is used to position and guide the lifting movable rod, and the positioning plate 3 is used to connect and fix with the operating platform; the lifting movable rod 1 is also connected to a guide structure, the lifting movable rod can move along the guide structure, and the guide structure is connected and fixed with the positioning plate 3. By controlling the active structure to drive the lifting movable rod 1 to move (lift and rotate), the "position" of the floor drain sand box placed and limited on the lifting top plate 2 can be adjusted and controlled, thereby saving adjustment time and improving production efficiency.

[0021] Further, in the embodiment, the lifting mechanism is installed at the "designed" position of the operating platform, that is, the positioning plate 3 is fixedly installed at the designed position. The top end of the lifting movable rod 1 of the lifting mechanism is connected to a lifting top plate 2 for placing a limiting sand box, and the bottom end of the lifting movable rod 1 is connected to a movable structure for driving the lifting movable rod to move. The lifting movable rod 1 is movably inserted on the positioning plate 3, and the positioning plate 3 is used to position and guide the lifting movable rod 1, and the positioning plate 3 is used to be connected and fixed with the operating platform; at the same time, the lifting movable rod 1 is also connected to a guide structure, and the lifting movable rod 1 can move along the guide structure, and the guide structure is connected and fixed with the positioning plate 3. In a specific implementation, the movable structure includes a first pulley 11 and a second pulley 12; one end of the lifting movable rod 1 away from the lifting top plate 2 passes through the first pulley 11 and the end is connected to the connecting plate 13, the first pulley 11 is fixedly connected to the lifting movable rod 1, the second pulley 12 passes through the connecting plate 13 through the rotating shaft and the end is connected to the output shaft of the servo motor 14, the servo motor 14 is fixed on the connecting plate 13, the first pulley 11 and the second pulley 12 are connected by belt transmission; a control structure for driving the connecting plate 13 to move is connected to the connecting plate 13. The control structure can be used to control the lifting (up and down) movement of the connecting plate 13 and the lifting and lowering movable rod 1 connected to the connecting plate 13, thereby realizing the adjustment of the "height" position of the floor drain sand box on the lifting top plate 3, and ensuring the quality of the floor drain sand box during compaction operation; the servo motor 14 set by the control is driven to rotate the second pulley 12 on the connecting plate 13, and the second pulley 12 drives the first pulley 11 to "rotate" around the connecting plate 13 through the belt, so that the first pulley 11 drives the lifting and lowering movable rod 1 to rotate, thereby realizing the "angle position" adjustment of the floor drain sand box placed on the lifting top plate 3 at the top of the lifting and lowering movable rod 1, thereby facilitating the accurate "compacting" of the floor drain sand box.

[0022] Furthermore, in the embodiment, the control structure includes a hydraulic cylinder 4, the output end rod body of the hydraulic cylinder 4 is hinged with a connecting rod 41, the connecting rod 41 is hinged to the fixed plate 5 through a hinge seat, the end of the connecting rod 41 away from the output end rod body of the hydraulic cylinder 4 is hinged with a movable block 42, and the end of the movable block 42 away from the connecting rod 41 is hinged to the connecting plate 13; the fixed plate 5 is used to be connected and fixed to the bottom of the operating platform; the cylinder body of the hydraulic cylinder 4 is connected to the fixed plate.

If height adjustment is required, the hydraulic cylinder 4 can be "extended" to drive the lifting movable rod 1 "rotatably" connected to the connecting plate 13 and the movable bearing 16 rotatably connected to the lifting movable rod 1 to "lift" along the movable guide cylinder 15 (the slider 161 on the movable bearing 16 "lifts" along the sliding groove adapted to the slider 161), thereby realizing the "height position" adjustment of the floor drain sand box on the lifting top plate 3, and thus, the "position" of the floor drain sand box is adjusted by the lifting mechanism to ensure the quality of "compacting" different floor drain sand boxes, thereby saving time and increasing production.
