Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of auxiliary equipment on board ships, in particular to a narrow inland river roll-on / roll-off ship loading and unloading structure. Background Art
[0002] Ro-ro ships are specially used for transporting various types of roll-on / roll-off cargo (such as cars, roll-on / roll-off trailers, container trucks, etc.). They have the advantages of high efficiency in loading and unloading cargo and convenient direct water-land transport. Therefore, they are widely used in the shipping industry. Ro-ro ships are mainly used for marine transportation or for cargo transportation on wide inland rivers, such as the Yangtze River and the Huangpu River. Due to the high cost of land transportation, inland river transportation is an ideal mode of transportation for some goods with low timeliness requirements due to its advantages of low cost and large transportation volume. In recent years, the transportation business of narrow inland rivers has also increased. For this reason, ro-ro ships are increasingly used for cargo transportation on narrow inland rivers. At present, narrow inland river ro-ro ships are mainly used to transport roll-on / roll-off trailers.
[0003] Normally, ro-ro ships sailing on the sea or wide inland rivers can carry more ro-ro cargo because of their wide hulls and multiple decks. However, for narrow inland rivers such as Xiaoqing River and Beijing-Hangzhou Canal, due to the narrow inland waterways, many inland bridges, small height space between bridges and river surface, and shallow river water, the width of the hull of narrow inland river ro-ro ships can only be designed to be very narrow and the draft is very shallow, resulting in the ship only having one deck to load ro-ro cargo. Therefore, the loading space of narrow inland river ro-ro ships is relatively small. For example, the ro-ro ship model JH-G3 sailing on the Beijing-Hangzhou Canal has a length of 90 meters and a width of 16.6 meters. If a ro-ro trailer with a length of 13 meters and a width of 2.6 meters is carried, a maximum of 4 lanes are set in the cabin along the width of the ship, and each lane can accommodate up to 5 rows of ro-ro trailers along the length of the ship. Therefore, for ro-ro ships sailing on narrow inland rivers, loading space is particularly precious. In addition, the roll-on / roll-off trailer requires a certain amount of turning space when moving in the cabin, but the length and width of the cabin are very narrow, resulting in insufficient turning space for the roll-on / roll-off trailer, making it difficult to load the roll-on / roll-off trailer to a fixed position on the leftmost or rightmost lane.
