[0002] Ships in the prior art are a general term for various ships. Ships are means of transportation that can sail and anchor in waters for transportation operations. According to different usage requirements, ships have different technical performances, equipment and structural types. The interior of the ship includes a storage space, a support structure and a drainage structure. It has a propulsion system that utilizes external or self-provided energy. The operation of the ship requires the use of a propeller. The rotation of the propeller can give the ship thrust. When the ship needs to stop, the propeller can give the ship resistance and slow down the ship. The propeller on the ship needs to use a lifting platform when installing. The propeller can be transported and lifted by the lifting platform, which can reduce the steps of manual handling and save manpower.

[0003] The patent application with publication number CN216190779U discloses a lifting platform for installing ship rudder propellers, wherein a plurality of ball bearing devices are fixed on the lifting base, the ball bearing device includes a ball bearing base, and balls are arranged in the ball bearing base; a ball bearing cover plate is provided on the upper cover of the ball bearing base, and a cover plate opening is provided in the center of the ball bearing cover plate, and the top of the ball bearing protrudes from the cover plate opening; the lifting installation body includes a support column fixed to the lifting base at the bottom end, a lifting connecting plate is horizontally extended from the top end of the support column in the direction away from the lifting base, and a vertically transparent bolt hole is provided at one end of the lifting connecting plate away from the support column; an adjusting hydraulic cylinder is installed at the edge of the lifting base, and the telescopic end of the adjusting hydraulic cylinder is perpendicular to the edge of the lifting base and faces inward. The platform of the present invention has the advantages of labor saving, stability, and high precision in the process of installing the ship rudder or propeller.

[0004] The lifting platform of the above-mentioned comparative document cannot support and limit the end of the propeller bearing away from the blades when in use. The front end of the propeller will shake, and it is necessary to manually lift the bearing port and insert it into the stern of the ship. The process is quite laborious. At the same time, when the ship is docked at the shore, the stern will be tilted or raised, and the angle of the propeller bearing cannot be adjusted according to the angle between the ship and the horizontal plane, resulting in installation difficulties.

[0005] In view of this, the present utility model is proposed. Utility Model Content
