The utility model discloses a railway vehicle side roof structure, including upper roof, transition board and lower roof, the three are connected in order from the middle part to the end part in the vehicle width direction; reinforcing ribs are arranged on the inner surface of the joint of the upper top plate and the transition plate along the length direction of the vehicle; reinforcing ribs are arranged on the inner surface of the transition plate along the length direction of the vehicle; the outer end of the upper top plate is provided with an upward arc-shaped turned edge along the length direction of the vehicle, and the end part of the arc-shaped turned edge is provided with a rotating shaft groove; and the outer end of the lower top plate is provided with an upward angular flanging along the length direction of the vehicle.
Furthermore, reinforcing ribs are arranged on the inner surface of the lower top plate along the length direction of the vehicle.
Furthermore, the thicknesses of the upper top plate, the transition plate and the lower top plate at the reinforcing rib position are 3.5-4.5 mm; the thicknesses of the upper top plate, the transition plate and the lower top plate at the rest positions are 3-4 mm.
Further, the number of the reinforcing ribs on the inner surface of the transition plate along the length direction of the vehicle is 2.
Furthermore, an included angle between the angular flanging at the outer end of the lower top plate and the surface of the lower top plate is an acute angle.
Furthermore, the reinforcing rib is of a sliding groove type, and a sliding groove nut is arranged in the groove. For mounting equipment in the side ceiling panels.
Furthermore, the upper top plate and the lower top plate are both planes, and the transition plate is a plane or an arc surface.
Rail vehicle side roof structure, the deformation problem when effectively having avoided side roof processing manufacturing has increased the security of whole piece, has reduced follow-up machining and the degree of difficulty and the transfer type cost and time that spray paint, and the current car of being convenient for is installed, and the installation effect is good, and is more pleasing to the eye, has reduced the production degree of difficulty and manufacturing cost.
Drawings
Fig. 1 is a sectional view of the side roof structure of the railway vehicle according to the present invention.
1-upper top plate; 2-a transition plate; 3-lower top plate; 4-reinforcing ribs; 5-arc edge curling; 6-a rotating shaft groove; 7-angular flanging.
Detailed Description
The structure of the side roof of the rail vehicle according to the present invention will be described in detail with reference to fig. 1.
As shown in figure 1, rail vehicle side roof structure, including last roof 1, cross cab apron 2 and roof 3 down, the three is connected in order to the tip by the middle part in vehicle width direction, it is dull and stereotyped to go up roof 1, cross cab apron 2 and roof 3 down.
And a reinforcing rib 4 is arranged on the inner surface of the joint of the upper top plate 1 and the transition plate 2 along the length direction of the vehicle.
Two reinforcing ribs 4 are arranged on the inner surface of the transition plate 2 at intervals along the length direction of the vehicle.
And reinforcing ribs 4 are arranged on the inner surface of the lower top plate 3 along the length direction of the vehicle.
