[0020] Reference Figure 1-3 A highly stable, anti-deviation marine lifting device includes a vertical column 2 and a suspension arm 8. The vertical column 2 has a receiving groove 21 on its side. A vertical seat 6 is rotatably connected to the top of the vertical column 2. A horizontal plate 1 is fixedly connected to the top of the vertical seat 6. An auxiliary column 81 is rotatably connected to the top edge of the horizontal plate 1. A suspension arm 8 is fixedly connected to the side of the auxiliary column 81. An electric hoist 9 is slidably connected to the suspension arm 8 in the horizontal direction. Both the suspension arm 8 and the electric hoist 9 are common devices in the prior art, so their detailed structures are not disclosed.

[0021] A drive assembly for rotating the suspension arm 8 is provided at the top of the horizontal plate 1, and an emergency release assembly for emergency release of the suspension arm 8 is provided at the top of the vertical column 2. The drive assembly includes a drive motor 4, a drive gear 3, and a driven gear 5. The drive motor 4 is fixedly connected to the bottom of the horizontal plate 1, and the drive gear 3 is fixedly connected to the output end of the drive motor 4. The drive gear 3 is stably meshed with the driven gear 5, and the driven gear 5 is fixedly connected to the outer wall of the auxiliary column 81. The number of teeth of the drive gear 3 is less than the number of teeth of the driven gear 5. The drive assembly can drive the entire suspension arm 8 to rotate to an appropriate position.

[0022] The emergency release assembly includes a release electric push rod 7, a buffer plate 10, a horizontal column 13, and a connecting spring 12. The horizontal column 13 is symmetrically fixed to the side of the buffer plate 10. The other end of the horizontal column 13 is movably inserted into the side of the vertical column 2. A connecting ring 11 is movably inserted into the outer wall of the horizontal column 13. The outer wall of the connecting ring 11 is fixedly connected to one end of the connecting spring 12.
