请结合参阅图1~2，本实施例公开了钢坯热送电动车的一种具体构造，包括车架组成1及分别设置于车架组成1上的隔热保温箱2与电驱单元，用以实现钢坯的保温热送及运输过程的电动化，达到洁净环保、高效低耗的作业目的。
可以理解，车架组成1可采用现有的电动车架结构。一般地，车架组成1包括车架本体及车轮，车轮的数量取决于钢坯热送电动车的运载要求。运载重量要求愈高，则钢坯热送电动车的轴数同步增加。例如，当钢坯热送电动车的轴数为二时，车轮的数量为四。
隔热保温箱2具有隔热保温性能，且顶部设置有可开合顶门21。隔热保温箱2内设置升降货架，升降货架可铅垂升降地穿过可开合顶门21以取放钢坯。
当可开合顶门21开启时，隔热保温箱2的内腔暴露，升降货架上升穿过可开合顶门21而伸出隔热保温箱2之外，自铸造车间的存放区顶取钢坯或将钢坯顶出至轧钢车间的存放区；当可开合顶门21封闭时，箱体内外不发生热交换，实现隔热目的，有效地减少钢坯的热损失，使钢坯到达轧钢线后无需二次加热即可接受轧制，生产效率有效提高。
示范性地，隔热保温箱2包括开口箱体及可开合顶门21，开口箱体顶部具有开口，可开合顶门21覆盖于开口箱体顶部的开口上。可开合顶门21可采用不同的结构形式实现启闭，例如卷帘门结构、直线滑动门结构、铰接转门结构等类型。可以理解，开口箱体与可开合顶门21分别具有隔热保温层，隔热保温层可为诸如发泡材料等隔热材料制成。
电驱单元位于隔热保温箱2之外，包括分别设置于车架组成1上的驱动电机31与电池组32。其中，驱动电机31用于驱动车架组成1（可具体为其中的车轮）行走，电池组32用于为驱动电机31供电。

示范性地，车架组成1上设有电池箱。电池箱位于隔热保温箱2之外，电池组32位于电池箱内，实现对电池组32的安全保护，防止外界冲击伤害。
示范性地，车架组成1上设有定位导航单元5，用于实现钢坯热送电动车的定位导航，为实现对钢坯热送电动车的位置导航控制提供硬件基础。示范性地，定位导航单元5包括激光探测器和/或GPS接收器。激光探测器通过发射及接收激光，实现于室内的位置定位；GPS接收器用于接收GPS卫星定位信号，获取钢坯热送电动车的当前位置，实现于室外的位置定位。
如前所述，升降货架具有铅垂升降运动。示范性地，升降货架包括升降驱动器与载架本体42。其中，升降驱动器的固定端与隔热保温箱2固定连接，升降驱动器的运动输出端与载架本体42固定连接。相应地，随升降驱动器的升降运动输出，载架本体42得以伸出于隔热保温箱2之外或收入于隔热保温箱2之内。可以理解，载架本体42与钢坯的外形相适应，使钢坯于运输过程中保持稳定，不致发生意外坠落。
升降驱动器可采用不同的结构形式实现。示范性地，升降驱动器包括相互平行的复数个伸缩缸41。其中，伸缩缸41的固定端固定于隔热保温箱2的内壁上、运动端固定于载架本体42上。可以理解，伸缩缸41可由电动推杆、电缸、齿轮齿条机构等形式替代。
示范性地，车架组成1上设有无线通信单元，用于实现与远程控制端的无线通信。具体地，无线通信单元可包括WiFi、移动通信网络等类型，相应具备对应的通信硬件。示范性地，车架组成1上设有控制箱6，用于实现对钢坯热送电动车的直接控制。示范性地，控制箱6可采用控制主板电路、微型计算机等类型实现。
最后所应说明的是，以上具体实施方式仅用以说明本发明的技术方案而非限制，尽管参照实例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的精神和范围，其均应涵盖在本发明的权利要求范围当中。
