实施例一：
本实施例提供了一种全铆接模块化中梁结构，中梁作为铁路平车底架的主要承载结构，具有三种功能:一是为车辆贯通承载件，为车辆载重提供支撑；二是将枕梁模块、横梁模块和大横梁模块联结成一个整体；三是在车辆发生纵向冲动时,参与能量的传递。因此,中梁模块要求具有较高的强度和刚度。
如图1-图2所示，本实施例的中梁结构包括两个牵引梁模块101和一个鱼腹梁模块102，两个牵引梁模块101关于鱼腹梁模块102对称安装。本实施例的中梁设计为三段模块式结构，且可以根据车辆长度需要通过改变鱼腹梁模块102长度改变底架长度，提高了灵活性。牵引梁模块101与鱼腹梁模块102铆接，相比现有焊接式的中梁结构，能够实现低焊接量、低污染、高效率和利于生产的自动化。
所述牵引梁101下部固定有上心盘104，用于连接转向架。牵引梁101内部安装丛板座103，用于连接车钩。所述牵引梁101采用冷弯槽钢铆接形成箱型结构，牵引梁101的端部与鱼腹梁102铆接。
具体的，如图3所示，鱼腹梁102由两个第一腹板105、若干第一盖板106和若干隔板107通过铆接形成箱型承载结构；第一腹板105端部通过铆接与牵引 梁101连接。第一腹板105、第一盖板106和隔板107为板材冲压成型部件，减少焊接及铸造件的使用及因此带来的焊接、铸造的污染、高能耗；板材冲压成型部件具有好的批量生产能力、好的尺寸精度和轻量化能力。
两个第一腹板105相对设置，第一腹板105的顶部和底部分别安装若干第一盖板106；隔板107间隔设置于第一腹板105、第一盖板106围成的箱型结构中。在本实施例中，第一腹板105设置多处镂空；第一盖板16和隔板107的结构相同，包括X型板，所述X型板的两端分别通过连接板相连。鱼腹梁模块102的零部件采用了板材镂空的减重结构设计，能够提高车辆的轻量化能力。
由于中梁主要承受垂向、纵向、扭转载荷，因此需保证中梁鱼腹段的垂向和扭转刚度，需要增大鱼腹段断面横向和垂向的截面模量(即断面尺寸)。而断面尺寸的增加与部件的轻量化相矛盾，本实施例采用有限元分析软件的拓扑优化功能，在模拟铁路平车极限组合工况下的受力情况，进行中梁鱼腹段结构的形状拓扑优化。并结合实际工程结构工艺得到鱼腹梁102的镂空减重结构方案。
本实施例的鱼腹梁模块102可以根据用户对车辆长度需要，在不改变底架及中梁总体结构的情况下，通过改变第一腹板105的长度及增加第一盖板106、隔板107的数量，实现中梁长度改变。
实施例二：
本实施例提供了一种全铆接模块化平车底架，包括实施例一所述的中梁结构1，还包括横梁模块2、枕梁模块3、大横梁模块4和侧梁模块5，将底架设计成五种尺寸较小的标准化模块。
如图4所示，大横梁模块4安装于中梁结构1中部；中梁结构1的两端对称安装有横梁模块2、枕梁模块3和侧梁模块5，横梁模块2安装于中梁结构1端 部，枕梁模块3与横梁模块2间隔设定距离，且横梁模块2和枕梁模块3的两端分别通过侧梁模块5相连。
本实施例中横梁模块2、枕梁模块3、大横梁模块4通过铆接连接到中梁结构1，侧梁模块5一端通过铆接连接到横梁模块2，另一端通过铆接连接到枕梁模块3。本实施例全铆接结构的底架，相比现有焊接结构底架，避免了焊接工艺产生的焊烟污染、焊接应力集中、焊接形变和焊接缺陷以及因此产生的结构尺寸调修和焊烟飞溅清除。
如图5所示，横梁模块2包括第二腹板201、第二盖板202和托板203，第二盖板202的底部两端均安装有第二腹板201，位于第二盖板202两端的第二腹板201之间形成牵引梁101的安装空间。第二盖板202的每一端安装两个第二腹板201，且两个第二腹板201间隔一定距离、与第二盖板202形成箱型承载结构。所述两个第二腹板201的底端连接托板203。本实施例中，第二腹板201、第二盖板202、托板203的连接均采用铆接。

如图7所示，枕梁模块3包括第三盖板301、第三腹板303和旁承座302，第三腹板303和第三盖板301分别与中梁结构1通过铆接连接。第三盖板301的底部两端分别安装两个第三腹板303，且第三腹板303与第三盖板301通过铆接形成箱型承载结构。连接于第三盖板301两端的第三腹板303之间形成牵引梁101的安装空间。
第三腹板303由钢板冲压形成周边折弯，第三腹板303中部可根据枕梁模块 3的需要开设减重孔。本实施例中，第三腹板303开设两个减重孔。所述第三腹板303的底部连接旁承座302，所述旁承座302用于与转向架接触，为车辆承载提供支撑。
如图8所示，大横梁模块4包括上盖板401、第一集装箱锁402、上横梁403、下横梁404、竖梁405和下盖板406，上盖板401的底部两端对称安装上横梁403、下横梁404、竖梁405；上横梁403、下横梁404、竖梁405和下盖板406由钢板冲压成形。所述上盖板401的顶部两端对称安装第一集装箱锁402。
进一步的，下横梁404倾斜设置，其一端与上横梁403铆接，另一端与竖梁405一端铆接；竖梁405另一端与上横梁403铆接。上横梁403、横梁404和竖梁405形成直角三角形的支撑单元。上盖板401的两端均铆接两个所述支撑单元，且支撑单元的底部连接下盖板406。位于上盖板401两端的支撑单元之间形成鱼腹梁模块102的安装空间。
如图9所示，所述侧梁模块5包括外侧梁501、内侧梁502，外侧梁501和内侧梁502通过铆接形成箱型承载结构。在本实施例中，外侧梁501、内侧梁502为U型板。外侧梁501的底部(以图9所示方向为参考)连接脚蹬503，外侧梁501顶部安装第二集装箱锁504。进一步的，第二集装箱锁504通过螺栓固定到外侧梁501上，通过固定位置调整，并配合大横梁模块4上的第一集装箱锁402，满足不同车辆配套标准载具的接口尺寸。
本实施例由冲压成型零部件铆接而成，避免了焊接，降低了零部件重量，提高了零部件尺寸一致性，有利于零部件批量化生产，提高底架的制造速度，降低车辆的制造成本。结构新颖，无焊接污染，自重轻，结构简单，制造和检修维护简易。
实施例三：
本实施例提供了一种铁路平车，包括实施例二所述的平车底架，所述平车底架底部安装转向架；所述转向架与牵引梁下部的上心盘相连。所述平车底架两端安装车钩缓冲装置。
以上所述仅为本申请的优选实施例而已，并不用于限制本申请，对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
