Ship lift lifting type double-steel-beam anti-collision system and redundant blocking and preventing method thereof

Abstract

The invention provides a ship lift lifting type double-steel-beam anti-collision system which comprises a double-blocking anti-steel-beam assembly, a supporting component assembly, a lifting driving device, a reversing device, a lifting connecting assembly and a supporting structure. The lifting driving device is arranged in the ship chamber main longitudinal beam structure on the side edge of theship reception chamber structure, the lifting driving device is connected with the double-blocking steel beam assembly through the reversing device and the lifting connecting assembly, and the double-blocking steel beam assembly can be driven by the lifting driving device to move up and down; the double-blocking steel beam assembly comprises an impact beam, a safety beam and a middle connecting device, the impact beam and the safety beam are fixedly connected through the middle connecting device, and the supporting structure is fixed to a ship chamber structure on the inner side of the safetybeam. Large safety redundancy is achieved, the collision force between the ship and the plastic beam is effectively reduced, and the adverse effect of the collision load of the ship colliding with the anti-collision beams on the ship compartment structure is reduced; a detachable connecting structure is adopted between the two stages of anti-collision beams so that the collision beam damaged by collision is convenient to replace; the ship lift lifting type double-steel-beam anti-collision system can meet blocking requirements of ships with bulbous bows.

Description

technical field [0001] The present invention relates to the ship lift project in the field of water conservancy and hydropower engineering, and more specifically relates to a method of implementing safety barriers when a ship stall accident occurs during the docking process of the ship lift to protect the door of the ship compartment from being hit by a stalled ship. mechanical device. Background technique [0002] As a navigation facility, the vertical ship lift is increasingly widely used in water conservancy projects because of its short dam crossing time and its suitability for high dam navigation. At present, the vertical ship lift used in my country's hydropower stations is the counterweight vertical ship lift. The fortification and protection of the ship stall accident is one of the important contents of the safety guarantee system design of the counterbalance ship lift. Especially when the ship box is in the docking state with the upstream, and the ship sails from t...

AI Technical Summary

Problems solved by technology

The anti-collision system cannot meet the interception needs of ships with bulbous bows

In addition, for a ship whose bow is too inclined, the impact stroke is too large, which may cause the ship to hit the cabin door
