[0002] A ship is a man-made vehicle that runs in water. Its manufacturing process is usually carried out in a shipyard's dock. Some manufacturers will first produce and assemble the ship's bottom structure, then place it in the dock to float, and gradually assemble the entire ship structure on the bottom structure.

[0003] Currently, the technology used to move a ship's bottom structure into a dock typically involves placing pulleys, rollers, and other structures on the bottom of the structure, using rolling friction instead of sliding friction to reduce resistance and assist in movement, or directly transporting the structure into the dock using lifting equipment. However, due to factors such as gravity and inertia, the structure often collides with the water surface or the edge of the dock, causing damage to the structure. Therefore, a device that can safely and stably transport the structure is needed to ensure construction safety. Utility Model Content
