Description

Technical Field

[0001] The invention relates to the technical field of shipbuilding, and in particular to a left and right rough positioning guide tool for docking a ship. Background Art

[0002] During the process of discharging ships, dry docks or floating docks are usually used for discharging operations. In the process of using floating docks, the left and right positioning deviations of the bow of the ship when docking are large, and it is easy to hit the dock wall. When the water level is lower than the safe water level, the central positioning of the ship when docking is required to be high. If it deviates, it may touch the bottom and scrape the bottom. Generally, during the floating dock discharging process, the required water level needs to be increased by 0.3m on the basis of the side pier height. For V-bottom ships, without adding a safe water level, the distance between the side piers is generally about 2m, that is, within 1m around the center line, the distance between the bottom of the ship and the baseline pier is 1.3m. If the left and right deviations during the ship docking process can be controlled within 0.7m, the demand for water level can be greatly reduced. Therefore, in order to reduce the cost of docking, it is urgent to reduce the positioning deviation of the ship. Summary of the invention
