[0028] In this embodiment, the connecting rod 35 can be driven by the reduction motor 34 to rotate the screw 36. The rotating screw 36 can cause the connecting plate 33 to move the push rod 321 downward, thereby pressing the lubricating oil in the cylindrical tube 32 into the circular tube 31 and spraying it out from multiple nozzles 311. Since the circular tube 31 is located above the lifting mechanism 2, the sprayed lubricating oil can fall on the lifting mechanism 2, increasing the lubrication effect of the lifting mechanism 2 and reducing the friction of the lifting mechanism 2.

A reduction motor 24 is fixedly connected to the side of one of the support plates 12. The output end of the reduction motor 24 passes through the support plate 12 at the corresponding position and is fixedly connected to the circular roller 21. A through hole is opened at the top of the gate frame 1 corresponding to the circular roller 21.
[0031] In this embodiment, by hooking the two hooks 23 onto the corresponding lifting rings 13, the roller 21 can be rotated by the drive of the geared motor 24.
