The driving motor 7 is mounted on the inner bottom wall of the driving box 203 by bolts, and the end of the shaft 701 is rotatably connected to the inner wall of the driving box 203. The tooth surface of the driving gear 702 passes through the square through hole 204 and is located above the annular block 602, wherein the driving direction of the driving motor 7 is a reciprocating 180°, thereby avoiding obstruction of the hose 604 to the position exchange of the two storage chambers 6021, and the two hoses 604 can facilitate the replenishment and replacement of the lubricating oil.

[0028] After the installation is completed, the staff supplies lubricating oil to the storage chamber 6021 located above the annular block 602 through the hose 604 located above, and the lubricating oil falls from the oil hole 603 and the oil hole 607 to the flange 4 to lubricate and protect it, while the excess lubricating oil will continue to move downward and enter the storage chamber 6021 located below from the oil hole 607 and the oil hole 603 below for collection, and the lubricating oil levels in the two storage chambers 6021 are monitored respectively by two S-BCS series capacitive liquid level sensors 6022. When the lubricating oil level in the storage chamber 6021 originally located above is insufficient, a signal is sent to the controller, and the controller sends an electrical signal to the drive motor 7. After receiving the signal, the drive motor 7 starts and drives the shaft through the output end The rod 701 rotates, and the rotating shaft 701 drives the installed driving gear 702 to rotate. The tooth surface of the driving gear 702 controls the annular block 602 to rotate through the meshing internal gear 605. The annular block 602 moves along the inner wall of the annular plate 601.

[0030] After the installation is completed, the staff supplies lubricating oil to the storage chamber 6021 located above the annular block 602 through the hose 604 located above, and the lubricating oil falls from the oil hole 603 and the oil hole 607 to the flange 4 to lubricate and protect it, while the excess lubricating oil will continue to move downward and enter the storage chamber 6021 located below from the oil hole 607 and the oil hole 603 below for collection, and the lubricating oil levels in the two storage chambers 6021 are monitored respectively by two S-BCS series capacitive liquid level sensors 6022. When the lubricating oil level in the storage chamber 6021 originally located above is insufficient, a signal is sent to the controller, and the controller sends an electrical signal to the drive motor 7. After receiving the signal, the drive motor 7 starts and drives the shaft through the output end The rod 701 rotates, and the rotating shaft 701 drives the installed driving gear 702 to rotate. The tooth surface of the driving gear 702 controls the annular block 602 to rotate through the meshing internal gear 605. The annular block 602 moves along the inner wall of the annular plate 601. During the movement, the two hoses 604 will stick to the outer wall of the annular block 602, and the oil hole 603 will be separated from the oil hole 607. At this time, when the storage chamber 6021 for collecting lubricating oil at the bottom moves, the contact surface between the annular plate 601 and the annular block 602 is lubricated through the oil hole 603 to ensure the rotation effect, and the storage chamber 6021 originally at the bottom is moved to the top to ensure that the collected lubricating oil re-lubricates the flange 4, and the storage chamber 6021 originally at the top is moved to the bottom to collect the lubricating oil.
