Ship body supporting structure of double-layer train trestle

Abstract

The invention relates to a ship body supporting structure of a double-layer train trestle. The ship body supporting structure comprises an upper-layer trestleship body supporting structure and a lower-layer trestle ship body supporting structure, the trestle ship body supporting structure comprises a trestle part and a ship body part; the ship body part comprises a vertical supporting plate transversely extending out of a ship body; a supporting panel with an upward arc-shaped bearing face is fixedly arranged on the vertical supporting plate; a rail web plate for supporting a train rail and adjusting the height of the train rail is arranged on a train deck of the ship body part; and the trestle part comprises an arc-shaped carrying plate matched with the supporting panel. The arc-shaped carrying plate is matched with the arc-shaped supporting panel, so that a certain seawater and tidal range fluctuation of a port can be allowed, and flexible connection is achieved. The height of the ship body part of the trestle ship body supporting structure is low so as to meet the height requirement of a vehicle cabin; and the lower-layer ship body part is high, so that the structural stability is improved.

Description

technical field [0001] The invention relates to a hull supporting structure of a double-deck train trestle, belonging to the technical field of train ro-ro ships. Background technique [0002] Train ro-ro ships can transport loaded trains from one port to another. When the train ro-ro ship is operating in the port, the tail of the ship and the trestle need to be closely connected together so that the train can safely board and disembark through the trestle. The interface between the train trestle and the ship has a small contact surface and a large local load; the marine environment and tidal range of the port also fluctuate from time to time. In order to ensure train safety, the trestle bearing structure must be able to overcome these difficulties and problems. [0003] At present, the train ro-ro ships are single-layer train decks, and the supporting structure of the existing trestle has the following disadvantages: [0004] 1) In order to meet the strength requirements...

AI Technical Summary

Problems solved by technology

[0004] 1) In order to meet the strength requirements, its geometric size is often relatively large, which increases the construction cost and affects the floor height of the vehicle compartment;

[0005] 2) Only the cooperation of single-layer train deck and single-layer train trestle can be realized

[0006] 3) The contact surface between the hull and the trestle is flat, which has low tolerance to seawater and tidal fluctuations in the port
