Auto-lift double-deck train ferry for strait and method
The present invention relates to a kind of auto-lift double-deck train ferry for strait, belong to water route transportation, special boat technical field.
The gordian technique of railway ferry is bank ship leveling and the bank ship steering rail butt joint of ferry when pulling in to shore operation.Existing river ferry influences the leveling of bank ship and the principal element of bank ship steering rail butt joint and the technology of employing: 1. tiding makes the ship rail plane of ferry and bank rail plane drop occur; Go ashore on the train railway carriage and the ferry floading condition is changed, influence bank ship steering rail and dock.To this, routine techniques is to take the ballast of ferry Ballast Tank to regulate dynamic leveling hull floading condition.But, adopt the time of going ashore on this method leveling operation and the train railway carriage long, influence handling efficiency; And manufacturing and designing of ferry ballasting system and wheel track docking system is very difficult.2. the river flows and makes ferry anchoring location difficulty.To this, routine techniques is to build an artificial bay, and the river is flowed to be reduced dynamic effects such as shaking of producing of ferry, swings, forms a relative static situation, makes the anchoring location realization easily of ferry.Simultaneously, single user wharf and frame are set on the bank set firmly fully, to satisfy the technical requirements of bank ship steering rail butt joint.But, adopt the investment of this methods engineering big, long in time limit, ferry cycle that puts into effect is long.The major cause that produces above two aspect shortcomings is the influence that ferry still seriously is subjected to aquatic environment as the too busy to get away water surface operation of buoyancy aid.Even resemble the ferry of the described band jack up of the GB2061191 of British patent turn-out track flat-bed double-decker, still can not break away from the fact that hull is influenced by aquatic environment.
The objective of the invention is to release a kind of under marine environment (much more abominable) than the inland river environment can realize the railway ferry and the method for the leveling of bank ship, the butt joint of bank ship steering rail.
Technical scheme of the present invention is: telescopic supporting leg is housed on the hull of railway ferry, has the outrigger support base on the foundation of sea floor on bank.When operation was pulled in to shore in ferry, supporting leg stretched out hull, was supported on the outrigger support base of seabed, to more than the wave splash zone, made hull not influenced down by sea situation the hull jacking, realized the butt joint of bank ship leveling and bank ship steering rail.
Below in conjunction with accompanying drawing invention is further stated.
Fig. 1 ferry state in place that pulls in to shore;
Ferry state when work in Fig. 2 ferry promenade deck;
Ferry state during the work of Fig. 3 ferry lower tween deck;
Fig. 4 ferry offshore state.
When hull 1 pulled in to shore, train railway carriage 3 was arranged in promenade deck 4 and lower tween deck 5 respectively, and supporting leg 2 and heavy pad 6 all do not stretch out.H

2On, ferry promenade deck 4 and bank leveling, the butt joint of bank ship steering rail, butt joint control apparatus 8 is firmly realized butt joint.Promenade deck train railway carriage 3 is gone ashore, and new railway carriage 9 is gone on board.Supporting leg 2 continues hull 1 jacking, ferry lower tween deck 5 and bank leveling, and the butt joint of bank ship steering rail, lower tween deck train railway carriage 3 is gone ashore, and new railway carriage 9 is gone on board.The used car skin is unsnatched in ferry, fill new railway carriage after, the height of decline hull 1.Then, pack up supporting leg 2 and heavy pad 6, the ferry offshore.Supporting leg and ferry hull are become one, or in be contained in hull; Or be hung on topside outward and the supporting leg lower end is in more than the freeboard.Leg structure can be cylinder, rectangular column or exposed throughout type truss.
