Rail passenger car multi-function board

Abstract

The invention relates to a multifunctional cab apron for a railway coach. The multifunctional cab apron is formed by bending or punching a whole piece of cut steel plate and sequentially comprises a cab apron face, a waterproof groove, a threshold face and a threshold vertical plate from outside to inside. The cab apron face is 45-56mm higher than the threshold face. The bottom of the waterproof groove is 20-30mm lower than the threshold face. The threshold vertical plate is perpendicular to the threshold face. Draining holes are longitudinally formed at the bottom of the waterproof groove. The ends of the threshold face and the threshold vertical plate are fixed with door frame vertical posts by means of welding. The ends of the waterproof groove are fixed with end wall channel steel by means of welding. Due to the fact that the cab apron is integrated with a threshold, provided with the waterproof groove and integrally formed by means of bending or die punching, a structure is simplified, welding seams are reduced, and workshop production efficiency is increased in the meantime. The multifunctional cab apron has functions of both cab aprons and thresholds, a good draining function, and can serve as a reference for similar structures with the cab apron faces higher than the thresholds.

Description

technical field

[0001] The invention relates to a rail passenger car multifunctional ferry board, and belongs to the technical field of rail vehicle body structure design. Background technique

[0002] The end of the domestic 25G vehicle adopts rubber windshield, the structure at the end wall crossing plate, the upper surface is a plane, the shape is simple, and it is formed by bending the pattern steel plate. The end door adopts a folding door, and the end door sill is welded on the crossing plate. The upper plane of the door sill is higher than the crossing plate surface. The crossing plate and the door sill are two independent parts. The door sill is fully welded on the plane of the crossing surface, the welding workload is large and the welding deformation is easy to occur, the process requirements are high, the assembly is troublesome, and the production efficiency is low. The sealing requirements for the welding seam are high, and there is a hidden danger that the rai...
