[0023] The present utility model provides a large-scale hydraulic lifting device for ports through improvement. The technical solution of the present utility model is as follows:

A rotating mechanism 2 is installed on the base 1. The rotating mechanism 2 includes a rotating seat 21 rotatably installed on the base 1. The top of the rotating seat 21 is fixed with a rotating platform 22, and the bottom of the rotating seat 21 is fixed with a worm gear 23. One side of the bottom of the base 1 is fixed with a driving motor 25. The output shaft of the driving motor 25 is fixed with a worm 24 that is in transmission cooperation with the worm gear 23. By driving the driving motor 25, the worm 24 can be driven to rotate. Cooperating with the worm gear 23, the driving work of the rotating seat 21 can be carried out, and then the rotating platform 22 can be driven to rotate, achieving the purpose of driving the transfer of goods. One side of the top of the rotating mechanism 2 is fixed with a turning seat 3. The top of the turning seat 3 is fixed with an extension mechanism 4. The extension mechanism 4 includes a base frame 41 fixed on the turning seat 3. An extension frame 42 is slidably connected inside the base frame 41. A first hydraulic rod 43 is fixed between the inner side of the extension frame 42 and the turning seat 3. By the first hydraulic rod 43, the extension frame 42 can be driven to slide along the base frame 41, and the overall length can be extended. The top end of the extension frame 42 is fixed with a winding and braking assembly 7. The winding and braking assembly 7 is wound and connected with a steel cable hook hanging member 9. The steel cable hook hanging member 9 includes a movable pulley group and a hook installed at the bottom of the movable pulley group. A steel cable is wound between the movable pulley group and the winding and braking assembly 7. One side of the base frame 41 is rotatably installed with a rotating frame 5.
