[0022] 1. The ship uses a vibration-damping combined lifting frame, which, by setting vibration-damping elements, utilizes the elastic vibration-damping performance of rubber columnar components to buffer and absorb vibrations in the upper functional areas. This reduces the transmission of vibrations and noise generated in the upper functional areas to the cabin areas through rigid support, thereby mitigating the noise impact on the cabins, improving the living comfort of passengers in the cabins, and ensuring the quality of rest for passengers in the cabins.

[0023] 2. The ship uses a vibration-damping combination lifting frame, which, by setting up vibration-damping springs, utilizes the resilience of the vibration-damping springs to further reduce vibration and noise in the upper functional area, thereby further improving the vibration-damping efficiency of the vibration-damping components.

[0024] 3. The ship uses a vibration-damping combined lifting frame. By setting up a main support frame and a suspension support frame, the outfitting components can be directly bolted through the first and second oblong holes, and then assembled onto the main support frame and the suspension support frame, making the installation of outfitting components in the service cabins more convenient and faster.

[0025] 4. The vessel uses a vibration-damping combined lifting frame, which uses pipe clamps, cable trays and duct supports to fix pipes, hold cables and place ducts respectively, thereby saving space in the cabin and further improving the living experience of cabin passengers.

[0026] 5. The vibration-damping combined lifting frame for this ship, by setting up reinforcement components, clamping connectors and covering connectors, makes the disassembly and installation of the main support frame faster by using reinforcement components, and makes the disassembly and installation of the suspension support frame faster by using connectors, making the lifting frame more flexible and efficient to use.

[0041] Working principle: When using this marine vibration damping combination lifting frame, the vibration damping element 2 is first installed on the fixed stud 1 welded to the hull. Then, the main support frame 3 is installed at the bottom of the vibration damping element 2 using the reinforcement 4 and connecting threaded stud 203. The suspension support frame 5 is installed at the bottom of the main support frame 3 using the clamping connector 6 or the covering connector 7. When vibration noise occurs in the functional area of ​​the upper deck of the ship, the vibration passes through the vibration damping element 2 and is damped by the elasticity of the rubber column 201. When vibration occurs, the annular bottom plate 205 moves towards the fixed plate 204. The vibration damping spring 209 further dampens the vibration of the lifting frame. The outfitting components are installed by bolts passing through the first oval hole 301 and the second oval hole 501. The pipe fixing clamp 8, cable bracket 9 and duct support 10 are used for pipe guidance, cable storage and duct placement, respectively.
