Method for increasing shipping efficiency of ship lock as well as roll-on roll-off vessel

Abstract

The invention discloses a method for increasing shipping efficiency of a ship lock as well as a roll-on roll-off vessel. A carriage body of the roll-on roll-off vessel is provided with a trough type frame, wherein a driving wheel unit is arranged at each of the left side face and the right side face of the trough frame, driving wheels of the driving wheel units are outward and face towards a lock wall of a lock chamber, and the driving wheels press on the lock wall of the lock chamber when the driving wheels are in operation. The driving wheel units are mounted on a movable guide rail; one end of a propulsion cylinder is connected to a fixed guide rail, and the other end of the propulsion cylinder is connected to the movable guide rail. The driving wheels are connected with an electric motor through a reduction gearbox. According to the roll-on roll-off vessel disclosed by the invention, positioning time can be reduced, wherein the positioning time refers to the process of locking in, slowing down, braking and mooring a cable of each vessel. Compared with a lockage process in the prior art, the entire lockage process of the roll-on roll-off vessel is equivalent to that only one vessel rolls on / off the lock chamber, without the process of mooring the cable, and therefore the roll-on and roll-off speed can be increased, and the positioning time is relatively short. As the roll-on roll-off vessel is designed to be matched with the lock chamber in dimension, automatic positioning and roll-on roll-off of the ship lock are easy to realize.

Description

technical field [0001] The invention relates to a method for improving the navigation efficiency of a ship lock and a rolling ship. The rolling ship is used in conjunction with a water conservancy dam ship lock, and is most suitable for a ship lock where multiple ships pass through the lock at the same time, especially a multi-stage ship lock like the Three Gorges ship lock. . Background technique [0002] There are 1,089 navigable structures under construction or already built in my country, including 1,041 ship locks, and 267 existing ship locks in the United States. The vast majority of rivers have been developed in steps. Out, such as the Gezhouba ship lock, the Three Gorges ship lock, and the Changzhou Water Conservancy Project lock. However, with the development of our country's economy, the requirements for the freight capacity of the golden waterway are getting higher and higher. On the other hand, it is mentioned in "Three Gorges Ship Locks Tightly "Stuck" the Gold...

AI Technical Summary

Problems solved by technology

This is a good way to reduce the time for a ship to pass through the lock, but the current methods generally use two methods when the ship enters the lock. One is to use the ship's propeller to propel the ship into the lock, slow down, brake, and position It is very time-consuming. The other is to use the tractor on the dam surface to pull the ship into the lock. The possibility of ship collision is small and the safety is good, but it is also time-consuming.
