附图说明
图1为本发明一种具体实施例中罐式集装箱的罐体的结构示意图；
图2为本发明一种实施例中罐体的横截面示意图；
图3为本发明另一实施例中罐体的剖视截面图；
图4为本发明一种实施例中罐式集装箱的剖视横截面示意图。
其中，图1至图4中：
封头1、筒形本体部2、第一轮廓段2a、第二轮廓段2b、第一筒体部21、第二筒体部22、加强筋3、框架4、卸货装置5。
具体实施方式
现有技术中罐式集装箱的罐体主要有三种结构，根据横截面形状的不同可以命名为：圆形截面罐体、椭圆形截面罐体以及多段弧围成的非圆截面罐体；各类型罐体的横截面均关于罐体中心对称。
其中圆形截面罐体和椭圆形截面罐体在集装箱框架内容积有限，目前20英尺标准容积最大能够达到26立方米，虽然此类罐箱压力等级较高，但是容积偏小，经济效益有局限性。
多弧段围成的非圆形面，虽然在标准框架内，容积能够增大，但是压力等级较小，多为运输普通液体，其加强圈焊缝焊接时容易引起罐体变形。
针对上述三类罐体存在的技术缺陷，本发明进行了深入研究并提出了一种兼顾压力等级及容积的技术方案，具体描述如下。
为了使本领域的技术人员更好地理解本发明的技术方案，下面结合附图和具体实施例对本发明作进一步的详细说明。
请参考图1、图2和图4，图1为本发明一种具体实施例中罐式集装箱的罐体的结构示意图；图2为本发明一种实施例中罐体的横截面示意图；图4为本发明一种实施例中罐式集装箱的剖视横截面示意图。
在一种具体的实施方式中，本发明所提供的罐式集装箱可以包括方形框架4和罐体，罐体设置于方形框架4的内部。方形框架4的横截面为具有一定厚度的方框。
罐体包括筒形主体部2，筒形主体部2的两端并与其固定连接有封头1，封头1的形状和结构根据筒形主体部2端部对接结构而定。筒形主体部2和两端的封头1形成容纳液体或者固体粉料的空腔。
本发明中的筒形主体部2的横截面为非对称结构，筒形主体部2的横截面包括第一轮廓段2a和第二轮廓段2b，第一轮廓段2a和第二轮廓段2b共同围成周向封闭轮廓。第一轮廓段2a为多个弧形段拼接的非圆轮廓段， 非圆轮廓段中各弧形段依次圆滑过渡连接，第二轮廓段2b为圆形弧轮廓段。
也就是说，圆形弧轮廓段与非圆轮廓段二者关于横截面的中心水平面非对称。
筒形主体部2可以由一块钢板弯折形成，即一块钢板弯折形成具有上述横截面形状的筒形主体部2，当然，也可以通过多块钢板拼焊形成上述筒形主体部2。
需要说明的是，本文中所述的多个通常是指三个或者三个以上。
与现有技术中采用对称横截面相比，本发明所提供的罐体的横截面轮廓由圆形弧轮廓段和非圆轮廓段组合形成非对称结构，圆形弧轮廓段对应的筒形主体部2不仅可以减轻自重，减少焊缝，增加罐体的压力等级，在同等载重的前提下，可以多装轻质货物以及低危化工品等，大大提高了罐体运输货物的适用范围，并且对于下部采用圆形弧轮廓段的罐体而言，筒形主体部2与框架4之间下侧部空间较大，方便安装侧面卸货装置5，提高罐体卸货灵活性；并且本发明中的非圆形弧轮廓段对应的筒形主体部2在一定程度上可以增大罐体的容纳空间。
综上，本发明所提供的罐体可以兼顾压力等级及容积两方面的使用需求。
具体地，筒形主体部2包括第一筒体部21和第二筒体部22，第一筒体部21与第二筒体部22为分体结构，二者对接焊接固定围成周向密闭空间，第一筒体部21的横截面轮廓为非圆轮廓段，第二筒体部22的横截面轮廓为圆形弧轮廓段。本文优先的实施方式中，第一筒体部21为上筒体，第二筒体部22为下筒体，并且本文以上筒体为非圆形轮廓、下筒体为圆形轮廓为例继续介绍技术效果。下筒体为圆形弧轮廓段，其压力等级相对比较高，有利于罐体内物料快速卸至外部，并且下筒体的侧下方与框架的间距比较大，利于布置侧面卸料装置，提高卸料装置布置的灵活性。
当然，上筒体的截面也可以为圆弧轮廓，下筒体的截面为非圆形轮廓。
圆形弧轮廓段的圆心位于筒形主体部2的横截面纵向中心线上。
第一筒体部21和第二筒体部22可以均为半筒体，也就是说，第一筒 体部21的横截面轮廓可以为半圆形，即180度的圆弧，该实施方式中第一筒体部21和第二筒体部22的对接面位于罐体的中心平面。当然，第一筒体部21的横截面的圆弧面也可以为小于180度的圆弧，第二筒体部22和第一筒体部21的对接平面低于罐体的中心平面；同理，第一筒体部21的横截面的圆弧面也可以为大于180度的圆弧，第二筒体部22和第一筒体部21的对接平面高于罐体的中心平面。图2中给出了以上三种情况，第一筒体部21和第二筒体部22的对接连接位置。
请参考图3，图3为本发明另一实施例中罐体的剖视截面图。
为了提高罐式集装箱罐体的使用强度，还可以进一步增加加强筋3。具体地，罐体还可以包括至少一组加强筋3，加强筋3为弧形结构，各组加强筋3沿筒形主体部2的轴向间隔布置，并且加强筋3固定于第一轮廓段2a对应的筒形主体部2的外壁或者内壁。图3中示出了加强筋3设置于筒形主体部2内壁的实施方式，图1中示出了加强筋3设于筒形主体部2外壁的实施方式。
也就是说，可以仅在非圆轮廓段对应的筒形主体部2上设置加强筋3，圆形轮廓对应的筒形主体部2无需设置加强筋3，这样在提高非圆轮廓筒形主体部2的前提下，尽量减少焊接量和降低罐体的重量，进而降低罐式集装箱整车的重量。
当然，加强筋3也可以为环形结构，设于整个筒形主体部2的内壁或外壁，进一步增强罐体的使用强度。
加强筋3的横截面有多种形式，可以为圆形、三角形、梯形、矩形、工字型、V型或者W型等等，也可以为它们其中几者的组合，可以为恒截面结构，也可以为变截面结构，在此不做赘述。
如上所述，罐体安装时，可以优选横截面为非圆形截面的第一筒体部21位于上方，横截面为圆形截面的第二筒体部22位于下方，这样罐式集装箱的卸货装置5可以位于圆形弧轮廓段对应的筒形主体部2和方形框架4围成的侧下方空间内部，圆形弧轮廓段对应的筒形主体部2和方形框架4围成的侧下方空间较大，便于卸货装置5各管路等其他零部件的布置。卸货装置5的具体结构可以参考现有技术，本文不做具体描述。
以上对本发明所提供的一种罐式集装箱及其罐体进行了详细介绍。本文中应用了具体个例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的方法及其核心思想。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理的前提下，还可以对本发明进行若干改进和修饰，这些改进和修饰也落入本发明权利要求的保护范围内。
