[0024] like Figures 1 to 4 As shown in the figure, a dual-suspension-point direct-drive gate hoist of this utility model includes a pair of gate hoist bodies 1; a synchronous shaft 12 is installed between the pair of gate hoist bodies 1; a rotating seat 13 is rotatably connected to the middle of the synchronous shaft 12; a pair of rotating seats 13 are arranged symmetrically in the middle of the synchronous shaft 12; a lead screw 11 is installed in the middle of the gate hoist body 1; a lubrication assembly is provided on the top of the gate hoist body 1 near the lead screw 11; a cleaning assembly is provided on the top of the gate hoist body 1; a manual assembly is provided on the side wall of the gate hoist body 1; during operation, the bottom ends of the lead screw 11 are connected to the top of the gate; when the gate hoist body 1 is started, the gate hoist body 1 drives the synchronous shaft 12 to rotate; the rotating seat 13 supports and guides the synchronous shaft 12; the synchronous shaft 1... 2. The two hoist bodies 1 rotate synchronously, simultaneously driving the lead screw 11 to rise or fall, thereby opening or closing the gate. When the hoist body 1 drives the lead screw 11 to rise or fall, the lubrication component lubricates the surface of the lead screw 11, and the cleaning component sweeps away impurities or foreign objects adhering to the surface of the lead screw 11. If necessary, the lead screw 11 can be raised or lowered by the manual component. This step, through the arrangement of the hoist body 1, lead screw 11, synchronous shaft 12, rotating seat 13, lubrication component, cleaning component, and manual component, forms a double-lifting-point direct-drive hoist structure, which improves the smoothness of gate raising and lowering, increases the load capacity of the device, reduces corrosion or abnormal wear of the lead screw 11, and extends the service life of the device.

[0031] During operation, the bottom ends of the lead screws 11 are connected to the top of the gate. When the hoist body 1 is started, it drives the synchronous shaft 12 to rotate. The rotating seat 13 supports and guides the synchronous shaft 12. The synchronous shaft 12 causes the pair of hoist bodies 1 to rotate synchronously, simultaneously driving the lead screws 11 to rise or fall, thus opening or closing the gate. As the hoist body 1 drives the lead screws 11 to rise or fall, the lubrication assembly lubricates the surface of the lead screws 11, and the cleaning assembly removes impurities or foreign objects adhering to the surface of the lead screws 11. If necessary, the lead screw 11 can be raised or lowered manually using the manual assembly. Lubricating oil is added to the oil box 25, and the lubricating oil permeates the sponge 23 through the oil channels at the bottom of the oil box 25 and inside the sliding plate 22.
