Embodiment Construction

[0017] Below in conjunction with embodiment the present invention is further described.

[0018] Such as Figure 1-Figure 4 As shown, the zigzag roof of the railway box car includes roof plate 5.1, ventilator 5.2, roof curved beam 5.3, roof side beam 5.4, car top curved beam 5.5 and car top plate 5.6; roof plate 5.1 is embossed Rib bending structure, the roof bending beam 5.3 is a flat steel bending structure, the roof side beam 5.4 and the top bending beam 5.5 are cold-formed angle steel; the two sides of the roof panel 5.1 in the middle overlap with the roof bending beam 5.3 , the roof panel 5.1 at the end is overlapped with the roof curved beam 5.3 and the top curved beam 5.5 respectively; both ends of the entire roof panel 5.1 are overlapped with the roof side beam 5.4; the top panel 5.6 is a steel plate embossed rib structure , the upper part of the top plate 5.6 is lapped with the curved beam 5.5 at the top of the car.

[0019] The roof panel 5.1 is a steel plate press...

Abstract

The invention discloses a dog-legged roof for railway boxcars, which belongs to the technical field of rail wagon manufacturing. The dog-legged roof disclosed by the invention comprises a roof panel, a ventilator, a roof carline, a roof cant rail, a roof end carline and a roof end panel, wherein the roof panel is in a pressed convex rib folding-pressing structure, the roof carline is in a flat steel folding-pressing structure, and the roof cant rail and the roof end carline are both made of cold-bending angle steel; the two sides of the roof panel in the middle are in lap joint with the roof carline, and the roof panel at ends is respectively in lap joint with the roof carline and the roof end carline; the two ends of the whole roof panel are in lap joint with the roof cant rail; and the roof end panel is in a steel-plate pressed convex rib structure, and the upper part of the roof end panel is in lap joint with the roof end carline. The profile of the dog-legged roof disclosed by the invention follows rolling stock clearance for railway, therefore, the rolling stock clearance for railway is used fully, so that the area of an internal section of a vehicle can be effectively expanded, the volume of the vehicle can be increased, the length of the vehicle can be shortened, and the dead weight of the vehicle can be reduced.

Description

technical field [0001] The invention relates to a railway freight car, especially a boxcar, and belongs to the technical field of railway freight car manufacturing. Background technique [0002] At present, boxcars are mainly used to transport all kinds of packaged goods, less-than-truckload goods and various bags, boxes and other packaged goods that are protected from the sun, rain and snow. The existing box car has an arc-shaped roof or a herringbone roof, which fails to make full use of the railway rolling stock boundary, which is not conducive to increasing the volume of the vehicle and reducing the dead weight of the vehicle. Contents of the invention [0003] In view of the above problems, the present invention provides a zigzag roof of a railway boxcar that can make full use of the boundaries of railway rolling stock. [0004] The technical solution adopted by the present invention to solve the technical problems is: the zigzag roof of the railway box car, includin...
