具体实施方式
为了使本技术领域的人员更好地理解本实用新型方案，下面结合附图和具体实施方式对本实用新型作进一步的详细说明。
为方便理解和描述简洁，下文结合铁路平车及其车体一并说明，有益效果部分不再重复论述。
铁路平车主要用于货物运输，可用于集装箱或者包装好的成捆货物，这些货物由铁路平车的车体支撑。
请参考图1，图1为本实用新型所提供铁路平车的车体的一种实施例的结构示意图。为清楚示意车体的结构，图1中车体靠近右边的部分未显示地板组成。
该实施例中，铁路平车的车体包括底架10和地板组成20，地板组成20设置在底架10上，用于承载运输的货物。
该底架10包括两个平行布置的侧梁11、位于两侧梁11之间的中梁12，以及连接的中梁12和侧梁11之间的第一横梁13。
侧梁11的长度方向与车体的长度方向平行，第一横梁13的长度方向与车体的宽度方向平行。
对于铁路平车来说，底架10还包括位于两端部的枕梁15，以方便与转向架相关结构配合。第一横梁13根据需要设置若干，沿底架10的长度方向间隔排布，通常来说，两边侧梁11与中梁12之间的第一横梁13的位置对应。
请一并参考图2，图2为图1中中梁的结构示意图。
该实施例中，中梁12设为箱型结构，且中梁12的中部区域的厚度大于其端部区域的厚度，以组装后实际使用状态来说，这里的厚度指的是高度方向。如图2所示，即中梁12两端部的高度相对较小，中部的高度相对较大，类似鱼腹形结构，在保证强度和刚度的基础上，可以大幅减重，有助于降低铁路平车的自重，从而有利于提升运输经济效益。
具体的，中梁12包括上盖板121、下盖板122和两个腹板123，两个腹板123相对设置，一个腹板123连接上盖板121和下盖板122的同一侧，形成箱型结构。各板之间通过焊接固定，通常选用钢板，能够在较小厚度的基础上保证强度和刚度。
其中，上盖板121为平面结构，以方便地板组成20的连接，下盖板122包括两个端部盖板区1221和中部盖板区1222，端部盖板区1221与上盖板121之间的距离小于中部盖板区1222与上盖板121之间的距离，如图2所示，如此使得中梁12整体呈中部尺寸大，端部尺寸小的鱼腹形结构。
在此基础上，为确保强度，盖板122的端部盖板区1221的厚度可相对 较大设置，中部盖板区1222的厚度可相对较小设置。根据应用需要，也可将腹板123的端部部分的厚度相对较大设置，中部部分的厚度相对较小设置。
组成中梁12的各板的材质和厚度设置等均可根据实际应用需求来设置，不局限于上述所述。
该实施例中，底架10的侧梁11可选用槽型钢结构，以利于降低车辆自重，具体的，可选用冷弯槽型钢。
请一并参考图3，图3为图1中地板的结构示意图。
该实施例中，地板组成20包括地板21，地板21具体可与中梁12和侧梁11固接，地板21为金属制成，可避免雨雪侵蚀，烈日暴晒等造成损坏，可延长车辆的检修周期，节约运维成本。
具体的，地板21可采用铁质或钢制地板，其厚度可相对较薄设置，比如说设为2.5～5mm。在此基础上，地板21上可以设置有一个以上的凸筋结构211，以提高地板21的刚度和强度。
该凸筋结构211可通过压筋的方式形成，在地板21上挤压形成该凸筋结构211。
该地板组成20还包括非金属垫条22，非金属垫条22的长度方向与车体的宽度方向平行，非金属垫条22固接在地板21上方，如图1所示，非金属垫条22与地板21配合，对货物进行支撑，替代原有的木地板，防止腐蚀易破损问题。
该方案中，底架10还包括设置在地板21下方的第二横梁14，第二横梁14固接在中梁12和侧梁11之间，具体来说，每侧的侧梁11与中梁12之间均固接有第二横梁14，为保证底架10结构各性能的均衡，两侧侧梁11与中梁12之间的第二横梁14的位置也对应设置。
具体的，第二横梁14可靠近非金属垫条22的位置设置，具体可以位于非金属垫条22的正下方，有一定偏差也可，以提高地板组成20的刚度和强度，如此，可以使地板组成20的地板21相对较薄设置，有利于降低车体自重。
可以理解，因底架10在侧梁11和中梁12之间还设有第一横梁13和枕梁15，所以在这些位置可以不设置第二横梁14，具体可根据实际布局和 需求来设置。
请一并参考图4，图4为图1中第二横梁的结构示意图。
该实施例中，第二横梁14包括横梁顶板141和横梁底板142，在横梁顶板141和横梁底板142之间连接有横梁腹板143，几者之间可通过焊接方式固定，可靠又便捷。各板件可选用钢板结构，相应可以较薄设置。
如图4所示，具体的，横梁腹板143选用波纹形结构，可理解为波浪形，如此有利于提高横向稳定性。
铁路平车在运输时，由于其车体整体呈类似平板状的结构，货物堆放在车体上后，无其他防护，存在被盗的隐患。该实施例中，铁路平车设有防盗罩。
请参考图5图5为本实用新型所提供铁路平车的防盗罩的一种实施例的结构示意图。
该实施例中，防盗罩30为具有开口的框架结构，使用时，其开口朝向铁路平车的车体，可罩设在车体的地板组成20上，以对货物起到防护作用。
如图5所示，该防盗罩30包括两个相对设置的侧墙部分31、两个相对设置的端墙部分32，以及墙顶部分33，每个部分均呈框架结构，以在满足防护的基础上，尽量地减轻自重。
其中，使用后，侧墙部分31大致沿车体的长度方向延伸，端墙部分32大致沿车体的宽度方向延伸，两个侧墙部分31的同一端之间连接有一个端墙部分32，侧墙部分31和端墙部分32的顶端连接墙顶部分33。
图示方案中，墙顶部分33主要分为两个部分组成，可以理解，实际设置时，也可连为一体结构。
如图6所示，侧墙部分31包括几个平行设置的横杆312，各横杆312通过多个平行设置的竖杆313连接在一起，侧墙部分31的两端分别设有两个侧杆311，在具体连接时，侧墙部分31的侧杆311与端墙部分32的对应端连接。
实际应用中，横杆312的数量及竖杆313的数量可根据需求来设置，此处不做限定。
具体的，位于最上方的横杆312和位于最下方的横杆312可采用U型槽钢结构，位于中部的横杆312可采用L型角钢；当然，在其他实例中， 各杆件也可采用其他的结构形式。
如图7所示，端墙部分32的结构组成与侧墙部分31类似，不再详述。
该实施例中，侧墙部分31和端墙部分32通过插接的方式连接，之后再通过紧固件固定，具体的，参考图8，侧墙部分31的侧杆311采用U型槽钢的形式，端墙部分32的对应端部可插入U型槽钢的槽内，两者之间再通过螺栓螺母等紧固件固接，该固定方式较为可靠。
如图9所示，墙顶部分33为框架形结构，其各杆件可采用L形角钢结构，与侧墙部分31和端墙部分32可通过紧固件连接。
该防盗罩30在其墙顶部分33还设置至少一个叉车梁34，叉车梁34的设置方便叉车转运防盗罩30。因通常来说，防盗罩30的长度较长，所以叉车梁34沿防盗罩30的宽度方向延伸，与端墙部分32的延伸方向一致。图示方案中，墙顶部分33设有两个叉车梁34，具体的，在侧墙部分31的顶部的横杆312上还固接有支座314，用以与叉车梁34配合。
如图10所示，该方案中，叉车梁34包括U形梁341，安装时，其开口朝向墙顶部分33，在U形梁341的内部可固接若干筋板342以提高其强度和刚度，在U形腔341开口的中部可固接盖板343，以使叉车梁34的中部区域形成箱型结构，有利于提高其刚度和强度。当然，可以理解，盖板343的长度和设置位置，不影响叉车梁34被叉车叉起的作用。
参考图5至图7，该例中，侧墙部分31和端墙部分32的顶端部均向防盗罩30的中心方向倾斜设置，具体来说，侧墙部分31两端的侧杆311向中心方向倾斜，端墙部分32两端的端柱321向中心方向倾斜，如此形成的防盗罩30呈上小下大的结构形式，在不使用时，可将几个防盗罩30叠放在一起，有利于防盗罩30的存放和转运。
具体的，可在防盗罩30的外侧固接至少一个支架314，该支架314具有朝上的支撑面，防盗罩30叠放时，上方的防盗罩30可以被下方防盗罩30的支架314支撑，有利于提高稳定性，可参考图11和图12理解。
图示方案中，将支架314设置在侧墙部分31的侧杆311上，每个侧墙部分31的两个侧杆311均固接有支架314，这样可以叠放时可以给上方的防盗罩30提高四个支撑面。支架314具体可采用L形角钢。
参考图1，该实施例中，铁路平车的车体上还设有至少一个限位部， 每个限位部与防盗罩配合，限位部包括四个限位座16，分别位于防盗罩30的四个角部，将防盗罩30罩设于车体后，其四个角部限制在四个限位座16之间，车辆运行时可对防盗罩30的纵向进行限位，避免防盗罩30在纵向窜动。
对于一个车体来说，防盗罩30的数量与车体的尺寸以及防盗罩30的尺寸相关，可以理解，当一个车体匹配两个以上的防盗罩30时，两个防盗罩30的邻接端可以共用限位座16。
以图1所示车体来说，一共设有六个限位座16，靠近图示左端的两个限位座16和位于中部的两个限位座16形成一个限位部，用以限制一个防盗罩30，位于中部的两个限位座16和位于图示右端的两个限位座16形成另一个限位部，用以限制另一个防盗罩30。
