[0002] The wharf ship collision buffer device is commonly known as a fender system or fender, which is a special device installed on the water surface of the wharf, berth, dock or other port structure. Its core functions are: 1. Absorbing impact energy, when the ship is berthing, mooring or unmooring, it is inevitable to contact or collide with the wharf structure; 2. The main role of the fender system is to absorb and dissipate the huge kinetic energy generated by the impact; 3. Protecting the ship, preventing the ship's hull, superstructure, propeller, rudder and other parts from being damaged in the collision; 4. Protecting the wharf structure, preventing the wharf wall, pile foundation, panel, mooring column and other structures from being damaged or deformed due to ship impact; 5. Assisting ship berthing operation, providing certain rebound force to help the ship position and stabilize during berthing.

[0003] Through retrieval, the present application discloses a ship collision buffer device, which can effectively absorb and disperse collision energy, reduce the impact force of the ship during collision, thereby effectively reducing the damage of the ship. The two main columns are moved in the operation bin by the air cylinder, and the two main columns simultaneously drive the turnover mechanism and the pushing mechanism to work. The turnover mechanism can change the position of the buffer mechanism, so that the maintenance personnel can quickly and efficiently complete the inspection, repair and replacement work of the device during daily maintenance, greatly reducing the maintenance cost and time. The pushing mechanism can enhance the stability of the positioning plate during work, ensuring the stability of the buffer mechanism during work.

[0004] The above technical solution has the following defects. Such wharf ship collision buffer device can adjust the position of the buffer mechanism through the air cylinder mechanism and the pushing mechanism. However, in actual use, the buffer mechanism is greatly impacted, which greatly burdens the tooth-shaped pushing assembly and the supporting assembly, affecting the service life of the device as a whole. Moreover, the buffer mechanism cannot be used during maintenance. In order to ensure the use strength of the buffer device, facilitate maintenance and replacement, and ensure the buffering function of the wharf during replacement, the present application proposes a wharf ship collision buffer device and a use method thereof, which innovatively designs a modular buffer unit, a ground maintenance path, low-maintenance transmission and precise positioning, completely restructures the maintenance logic of the wharf anti-collision device, and changes the traditional "stop and disassemble for major repair" to "replace and go for quick repair", significantly improving the continuity and economy of wharf operation.
