Compared with the traditional structure, the novel structure mainly has the following innovation points: after the roof framework structure is arranged in the invention, the structures such as the air outlet framework, the diffuser, the passenger room top lamp and the like arranged in the subsequent process can be moved upwards, the whole passenger room space is partially released, and the comfort level of passengers is improved. Secondly, electrical components (such as a wiring board, a power box and the like) of the lamp at the top of the passenger room are arranged in a space below the hanging arm, the space is of a through-long space structure in the longitudinal direction of the vehicle body, no other components are occupied, the lamp can unify the installation positions of the electrical components, the lamp models can be unified, the lamp types are reduced, and the production and the installation of the components are convenient.
The invention presents a novel design of a built-in roof framework structure of a railway vehicle by changing the section structures and connection modes of hanging arms, longitudinal beams and cross beams, and the structure has the following advantages:
1. the structure is simple, and the installation is convenient;
2. part of the passenger room space can be released, and the comfort level of passengers is improved;
3. the lamp variety is reduced, and the production and the installation of the components are convenient.

Detailed Description
Embodiments of the present invention will be explained below with reference to the drawings.
As shown in fig. 1, the built-in roof skeleton structure of the railway vehicle of the present embodiment includes hanging arms 1 hung below a roof steel structure and provided on both sides, and a cross member 4 provided across the middle of the vehicle. The hanger arms 1 are arranged at intervals in the longitudinal direction of the vehicle, and the top ends of the hanger arms are longitudinally adjustably fixed in C-shaped grooves of a roof steel structure through bolts. The hanging arm 1 is herringbone and is provided with two hanging claws, and the shape is regular. The lower part of the outer lifting claw is fixed with a longitudinally extending outer longitudinal beam 2, and the lower part of the inner lifting claw is fixed with a longitudinally extending middle longitudinal beam 3. The outside stringers 2 are profiled sections with cavities and hooks for providing a mounting interface for the interior components. The outer end of the outer side member 2 has a C-shaped groove for fixing the inner side roof panel. The middle longitudinal beam 3 is L-shaped, and the inside of the middle longitudinal beam is provided with reinforcing ribs, so that the overall strength of the middle longitudinal beam 3 is improved.
The luminaire 8 is mounted in the area between the two lifting fingers. In this embodiment, the lamp 8 includes a lamp body and a lamp cover, the outer side of the lamp cover is hinged and fixed on the outer side of the lamp body, and the inner side of the lamp cover is connected to the inner side of the lamp body through a quick locking device. The outer side of the lamp 8 is rotatably arranged on the outer side longitudinal beam 2 through a hook provided by the outer side longitudinal beam 2, and the inner side of the lamp 8 is detachably fixed at the lower end of the middle longitudinal beam 3 through a quick nut.
