Description

Technical Field

[0001] The invention belongs to the technical field of vehicle transport ships, and in particular relates to a buffer device, a lifting system and a ship. Background Art

[0002] Ro-ro ships have a special shape, with a tall hull and several floors. Most of them have a bulbous nose at the bow, a straight line in the middle, and a square tail at the stern, with a gate or a gangway. When sailing, a foldable stern gangway stands at the stern, and superstructures such as the driving platform are set at the stern or bow. There are no cargo hatches, cranes, or lifting equipment on a ro-ro ship. The bow is a living room, the stern is an engine room, and the middle is a large cargo hold. There are multiple decks in the large cargo hold, which are connected by ramps. The ramp is 30 to 40 meters long and 4 to 5 meters wide. There are movable and fixed ones. A large gangway is erected high at the stern. After the ship docks, the gangway is lowered, and freight vehicles loaded with containers drive up and down to carry out container loading and unloading operations. Freight vehicles on ro-ro ships can not only enter and exit from the stern of the ship, but also drive to the decks of the cabin to load and unload containers. RoRo ships have multiple decks for the placement of cargo units, and the upper deck is a flat surface. Each deck is connected by a ramp for vehicles to pass through. The loaded vehicles need to walk along a long ramp to reach the destination. Therefore, in order to reduce the driving section of the vehicle, the vehicle is transferred to the corresponding deck layer. The lifting equipment needs to be stable during the rising and falling process to avoid vibration during the operation of the elevator and reduce the risk of the vehicle being scratched.
