Top slab connecting structure inside railway train roof

Abstract

The invention relates to the technical field of railway train roofs and discloses a modular designing and manufacturing method of a top slab curved connecting structure in a railway train roof. The top slab connecting structure inside the train proof comprises an intermediate top slab, side top slabs, connecting assemblies of the intermediate top slab and the side top slabs and connecting assemblies of the side top slabs and a train body. Connecting parts of the side top slabs and the intermediate top slab are arranged on air duct affiliated hanging codes through large-stroke screw parts; top slab hanging codes are arranged on an air-conditioning air duct; and the connecting parts of the side top slabs and the train body are fixed on inserts of a C-shaped groove of the train body through fixing clamping pieces of the side top slabs. The curved connecting structure can effectively reduce noise in the train body, improve the fireproofing capability in the train body, can be convenient to overhaul air-conditioning air outlet duct components at the upper part of the top slab in a carriage, ensures uniform air outlet of an air conditioner and greatly improves the comfort and the practicability for passengers to take a seat.

Description

technical field [0001] The invention relates to the technical field of railway passenger car roofs, in particular to a modular design and manufacturing method of an internal roof curved connection structure of a railway passenger car roof. Background technique [0002] The roof is an important part of the interior decoration of the railway passenger car, and the roof interior roof plate of the existing railway passenger car is made up of two side roof plates in the middle roof and both sides. The side roof is used to cover the area between the rear cover of the luggage rack and the roof in the middle of the compartment. The upper side of the bottom of the side roof can provide space for the installation of air-conditioning branch pipes. In some parts, such as the side roof of the dining car, it can be Install lighting fixtures. The middle roof is the roof under the air-conditioning duct of the compartment, and the air-conditioning outlet is arranged on the roof. [0003] I...

AI Technical Summary

Problems solved by technology

[0004] The direct rigid connection with the car body or the use of simple rubber pads used by most of the existing railway passenger car roof systems cannot fundamentally reduce noise and vibration isolation; The air velocity is high, resulting in very low temperature near the air-conditioning outlet, and the passengers far away from the air-conditioning outlet will feel very hot, the temperature difference in the compartment is large, the blowing is uneven, and the comfort of passengers is reduced
