Detailed Description

The plate structure of the side guard plate of the through passage of the railway vehicle is described in detail with reference to fig. 1.

The utility model relates to a side guard board panel structure of a through passage of a railway vehicle, which comprises a middle plate 1, a transition plate 2, a chamfer plate 3 and two end plates 4.

The middle plate 1 is an arc-shaped plate, the distance between two arc-shaped end points of the cross section comprises 401mm or 441mm or 541mm or 661mm according to specifications, the arc is gentle, the arc radius of the cross section is 1398mm, and the thickness of the middle plate 1 is 2.5 mm.

The two ends of the cambered surface of the intermediate plate 1 are connected with the transition plate 2, the arc radius of the cross section of the transition plate 2 is 1398mm, the arc radius of the cross section of the intermediate plate 1 is the same, the arc lengths of the cross sections of the intermediate plate 1 and the transition plate 2 are respectively 510mm, 550mm, 650mm and 770mm according to specifications, and the thickness of the transition plate 2 is 1.5 mm.
