The invention discloses an improved wagon rear carriage side door board. The improved wagon rear carriage side door board comprises a side board; an L-shaped board is arranged at one end of the side board; a groove is formed by the L-shaped board and the side board; an opening of the groove faces towards the other end of the side board; a welding board is clamped and embedded into the groove; the length of the welding board is larger than that of the groove; the end, exceeding out of the groove, of the welding board is used for being welded to a rear board; and a fixing bolt penetrates through the side board, the welding board and the groove to fix the welding board into the groove. As the welding board fixed into the groove and the rear board are welded, direct welding between the side board and the rear board is avoided, and accordingly separation of the side board and the rear board can be achieved easily by taking out the welding board, disassembly is very convenient, and a rear carriage is convenient to move and transport; and under the action of the groove and the fixing bolt, the welding board and the side board have the good connection strength, so that the connection strength of the side board and the rear board is also ensured, and the overall connection strength of the rear carriage is improved.
Description
technical field [0001] The invention relates to a side door panel, in particular to an improved side door panel of a rear compartment of a railway freight car. Background technique [0002] The side door panels and rear door panels of the existing railway freight car rear compartments are all welded together directly. There are several disadvantages in this connection method: first, the side door panels and rear door panels of the rear compartment are completely welded, and it is very inconvenient to disassemble First, the movement and transportation of the rear compartment is not very convenient; second, the connection strength between the side door panel and the rear door panel is not high. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, provide an improved railway wagon rear compartment side door panel with high connection strength to the rear door panel and easy disassembly. [0004] Technical soluti...
