运输箱可以是集装箱，也可以是各种运输车的车厢。
如图1-4所示，本发明一实施例的燃料组件运输容器的运输固定方法，可包括以下步骤：
S1、将两个定位结构件30相间隔平行放置并固定在运输箱10的底板内。
定位结构件30可由多个板材拼焊成型，整体呈长条状，横截面可呈矩形等多边形。两个定位结构件30分别以一长边相对间隔排布在运输箱10内，通过螺栓组件可拆卸固定在运输箱10的底板上。
如图2、3所示，每一定位结构件30的至少一侧边设有定位卡槽31，可与燃料组件运输容器20底部的触地足配合，实现燃料组件运输容器在定位结构件30上的卡合固定。
优选地，定位结构件30的相对两侧边分别设有定位卡槽31。其中，定位结构件30的一侧边设有居中的一个定位卡槽31，相对的另一侧边设有间隔相邻的两个定位卡槽31，从而可以根据需要在其上卡合固定一个或并排的两个燃料组件运输容器。每一侧边上的定位卡槽31形成在所在侧边上设置的两个凸柱32之间。
适用于本发明的燃料组件运输容器20，参考图1、2、4，燃料组件运输容器20的底部两端分别设有触地足21，触地足21上设有销槽（未图示）。燃料组件运输容器20的顶部两端分别设有与触地足21上的销槽相适配的定位销22。具体地，燃料组件运输容器20底部每一端的触地足21由凸出设置且相间隔平行的两个条形支腿形成；销槽为条形支腿上设置的通孔。燃料组件运输容器20顶部每一端的定位销22形成在吊装盒上。
本实施例中，将两个定位结构件30以具有两个定位卡槽31的一侧相背，放置固定在运输箱10的底板内。两个定位结构件30之间的距离取决于燃料组件运输容器20底部两端的触地足21的距离。
S2、将多个燃料组件运输容器20以至多两层叠放在定位结构件30上。
每一层包括一个或两个并排的燃料组件运输容器20。
位于下层的燃料组件运输容器20的底部两端的触地足21分别卡合在两个定位结构件30的定位卡槽31内。位于上层的燃料组件运输容器20的底部两端的触地足21上的销槽分别与下层的燃料组件运输容器20的顶部两端的定位销22配合，即定位销22穿进销槽，对上层的燃料组件运输容器20进行定位和约束。
具体地，该步骤S2可包括如下步骤：

其中，每一燃料组件运输容器20的两端横跨在两个定位结构件30上，燃料组件运输容器20的底部两端的触地足21分别位于两个定位结构件30相背的一侧，分别与每一定位结构件30背侧的定位卡槽31相对应。
燃料组件运输容器20通过其触地足31卡合到定位卡槽31内，构成触地足31的每一条形支腿与对应的定位卡槽31一侧凸柱32相抵接，实现在定位结构件30上的固定。
两个燃料组件运输容器20相邻放置，分别通过触地足31和定位卡槽31的卡合固定在定位结构件30上。
S2.2、在下层燃料组件运输容器组中两个燃料组件运输容器20之间安装限位缓冲装置40进行缓冲限位，限制燃料组件运输容器20向中间靠拢的趋势，对燃料组件运输容器20起到防护的作用。
如图4、5所示，限位缓冲装置40包括相对设置的两个连接板41、穿设在两个连接板41上进行锁紧的锁紧组件42。两个连接板41上分别设有与燃料组件运输容器20侧面的法兰板23上紧固件对应的通孔（未图示）。

锁紧组件42可包括连接杆421以及配合在连接杆421上的锁紧件422。连接杆421可以是螺杆，从上自下或从下自上穿接在两个连接板41上，位于两个燃料组件运输容器20之间的间隔中。锁紧件422可以是螺母或螺接头等件，与连接杆421螺纹配合，将连接板41和连接杆421进行锁紧。

通过限位缓冲装置40在上层燃料组件运输容器组中两个燃料组件运输容器20之间的安装，将相邻的两个燃料组件运输容器20相对固定连接，限制燃料组件运输容器20向中间靠拢的趋势，对燃料组件运输容器20起到防护的作用。
S3、使用至少一组绑带50绕过上层的燃料组件运输容器20的顶部并拉紧捆绑在运输箱10上，防止燃料组件运输容器20发生上下窜动，从而完成燃料组件运输容器20在运输前的装载固定。
具体地，绑带50沿着燃料组件运输容器20顶部吊装盒的位置，竖直方向布置并捆绑锁紧，保证燃料组件运输容器20可以稳固在集装箱等运输箱10内。
优选地，使用两组绑带50分别绕过上层的燃料组件运输容器20顶部两端的吊装盒并拉紧捆绑在运输箱10上，使燃料组件运输容器20轴向两端均被捆绑约束。绑带50可选尼龙带。
结合图1-5，本实施例的燃料组件运输容器的运输固定方法，实现四个燃料组件运输容器20在运输箱10内的双层叠放固定。燃料组件运输容器20底部通过定位结构件30进行固定与限位，防止在运输箱10内部发生左右或前后的移动；同一平面（同层）上的两个燃料组件运输容器20中间通过安装限位缓冲装置40限制燃料组件运输容器20向中间靠拢的趋势，对燃料组件运输容器20起到防护的作用。整体具有较高的稳定强度与可靠性，且可以很好的提高运输效率。
