Bottom plate transportation type bridge passing ship lock

Abstract

The invention provides a bottom plate transportation type bridge passing ship lock. The ship lock is arranged in a river channel under a bridge and comprises an upstream lock, a midstream lock, a downstream lock, an upstream lock chamber, a downstream lock chamber and a water pumping device, wherein conveying rails are arranged at the tops of edge walls of the two lock chambers respectively; each conveying rail is internally provided with two hoists; a transportation rolling wheel is arranged at the bottom of each hoist; the hoists can move in the corresponding conveying rails through the corresponding transportation rolling wheels; a lifting rope which vertically falls into water is arranged on the side face, facing the corresponding lock chamber, of each hoist; and the lifting ropes are fixedly connected with a transportation bottom plate. By virtue of the bottom plate transportation type bridge passing ship lock, the water amount needing to be pumped in a ship navigation process is reduced, the electric quantity consumed by pumping water is reduced and the time spent on pumping the water is shortened; and the ship navigation efficiency is improved and the navigation time is shortened.

Description

technical field [0001] The invention relates to a floor transport type bridge-crossing ship lock, which is a kind of civil engineering for assisting large ships to pass through bridges with insufficient clearance height, and belongs to the field of auxiliary civil engineering for water surface traffic. Background technique [0002] At present, the Yangtze River, the Yellow River and other river basins have a large number of ships, but they are limited by the lack of headroom during bridge construction. Taking the Nanjing Yangtze River Bridge as an example, only 3,000-ton ships can pass through during the wet season, and it is impossible for 10,000-ton foreign ships to pass. The role of the Yangtze River. The water volume of the Yangtze River is six times that of the Rhine River, the largest river in Europe, but its transportation volume is only 1 / 6 of that of the Rhine River. Due to the insufficient headroom of Nanjing Yangtze River Bridge and other bridges, 10,000-ton ship...

AI Technical Summary

Problems solved by technology

The traditional bridge ship lock is composed of cofferdam, upstream and downstream gates, lock chamber pumping device, and gate opening and closing device. However, it takes a long time to use the water pump to drain the 9m-high water in the lock chamber, and the large amount of water that is pumped out is easy to cause downstream Fluctuations in the water surface affect the safe passage of ships
