The invention discloses a light-weight flat plate type door structure, relates to the technical field of carriage doors, and solves problems that a door plate part of an existing steel flat plate carriage door is heavy, as hinges are connected with the door plate through through bolts, gaps exist between bolt holes and the bolts, and the door plate falls greatly after being used for a period of time. The light flat plate type door structure comprises a door plate transverse frame and a large door side vertical pipe, wherein the large door side vertical pipe and a small door side vertical pipeare welded to two sides of a long edge of a flat plate type door plate respectively, a hinge is directly welded on a vertical rectangular pipe, a falling problem caused by mounting bolts of the hingeand the door plate is completely eradicated, a large number of rectangular tube grid frameworks in an existing carriage door are reduced, an external steel plate is changed into a high-strength steelplate with the thickness of 1 mm, so the overall weight of a single door can be reduced to 65-70 kg, the reduction amplitude reaches about 20%, on the premise that cost is not increased, a single vehicle can be reduced by 60 kg, and the manufacturing time can be reduced by about 10%.
本发明公开了一种轻量化平板式门结构,涉及车厢门技术领域,解决了现有的钢质平板车厢门门板部分重量较大,且由于铰链通过对穿螺栓与门板连接,螺栓孔与螺栓之间存在间隙,门板使用一段时间后会出现较大下坠的问题。一种轻量化平板式门结构,包括门板横框和门侧大竖管;所述门侧大竖管和门侧小竖管分别焊接在平板式门板的长边两侧。铰链直接焊接于竖向矩管上,杜绝了铰链与门板的安装螺栓引起的下坠问题,且由于减少了现有车厢门内大量矩管网格骨架,外部钢板改为1mm厚的高强度钢板,故单个门整体重量可下降至65‑70kg,下降幅度达20%左右,在成本不增加的前提下,单车可下降60kg,且制作工时可减少10%左右。
