一种冷藏车车厢密封结构及其作业方法 技术领域
本发明涉及冷藏车的车厢， 具体的说是一种冷藏车车厢的密封结构以及 该结构的作业方法。 背景技术
目前， 国内市场上的冷藏车厢主要是釆用 "三明治" 方式粘接制作的厢 板拼装， 组成车厢的左侧板、 右侧板、 顶板、 底板、 前板之间的接合处依靠 螺栓紧固或高强度结构胶加铝型材铆接紧固， 这些连接方式可以保证每块厢 板之间形成可靠的连接， 保证厢体连接强度， 但是各厢板的接合位置无专门 的处理， 间隙内会存在较大的热对流，处理不好甚至会出现内外联通的间隙， 形成冷气的泄漏通道， 造成冷能损耗， 影响车厢的保温性能。 发明内容
本发明所要解决的技术问题是提供一种冷藏车车厢密封结构及其作业方 法， 使得车厢厢体结构简单、 制造简便， 可以有效减少冷藏车厢冷气外泄或 冷能传导。
为解决上述技术问题， 本发明的其中一个技术方案是： 一种冷藏车车厢 密封结构， 所述冷藏车厢由釆用聚氨酯作保温层的夹芯厢板组成， 所述厢板 包括左侧板、 右侧板、 顶板、 底板、 前板、 后门板； 所述左侧板、 右侧板、 顶板、 底板、 前板之间相互接合的位置均设有缺口；
所述左侧板与底板之间的缺口形成一个灌注槽， 所述左侧板与顶板之间 的缺口形成一个灌注槽， 所述左侧板与前板之间的缺口形成一个灌注槽； 所述右侧板与底板之间的缺口形成一个灌注槽， 所述右侧板与顶板之间 的缺口形成一个灌注槽， 所述右侧板与前板之间的缺口形成一个灌注槽； 所述顶板与前板之间的缺口形成一个灌注槽； 所述底板与前板之间的缺 口形成一个灌注槽； 所述灌注槽内充满高密度聚氨酯。
左侧板、 右侧板、 顶板、 底板、 前板之间的接合处设有灌注槽， 相当于 在厢板之间增加了一个过渡带， 在这个过渡带上填充物料可使相互接合的厢 板连接在一起。 本发明利用了高密度的聚氨酯灌注材料作为填充物料， 聚氨 酯填充至灌注槽后， 由于与厢板材料一致， 且以其较好的绝热性和粘合性， 可以将相互接合的厢板连接成为无间隙的一个整体。 该种结构的冷藏车厢结 构简单， 且密封效果好， 厢板间不容易出现漏冷现象。
作为改进， 所述左侧板、 右侧板、 顶板、 底板、 前板之间的接合处设有 内包边。 内包边可进一步加固厢板之间的连接。
作为改进， 所述左侧板、 右侧板、 顶板、 底板、 前板之间的接合处设有 外包边。 外包边可进一步加固厢板之间的连接。
作为改进， 所述内包边和外包边与厢板之间为螺栓或铆接紧固。
本发明的另一个技术方案是： 一种冷藏车车厢密封结构的作业方法： 具 体步骤如下：
A. 在构成车厢的左侧板、 右侧板、 顶板、 底板、 前板之间将要接合的位 置切出缺口或在左侧板、 右侧板、 顶板、 底板、 前板发泡时直接成型 出缺口；
B. 将左侧板、 右侧板、 顶板、 底板、 前板组装起来形成一个无后门板的 车厢， 在车厢后端安装后门框；
C. 先向处于水平的灌注槽灌注，
向左侧板与底板之间的缺口形成的灌注槽内灌注聚氨酯灌注材料， 向左侧板与顶板之间的缺口形成的灌注槽内灌注聚氨酯灌注材料， 向右侧板与底板之间的缺口形成的灌注槽内灌注聚氨酯灌注材料， 向右侧板与顶板之间的缺口形成的灌注槽内灌注聚氨酯灌注材料， 向顶板与前板之间的缺口形成的灌注槽内灌注聚氨酯灌注材料， 向底板与前板之间的缺口形成的灌注槽内灌注聚氨酯灌注材料。
D. 再向处于竖直方向的灌注槽灌注，
向左侧板与前板之间的缺口形成的灌注槽内灌注聚氨酯灌注材料， 向右侧板与前板之间的缺口形成的灌注槽内灌注聚氨酯灌注材料。
E. 将后门板安装在后门框上。
灌注槽结构简单，操作简便， 高压灌注后， 灌注槽内将充满聚氨酯材料。 在发泡过程中， 由于聚氨酯会出现膨胀， 厢板接合处的所有间隙将会被聚氨 酯材料填满， 并将铆钉紧固间隙胀紧无松动， 切断了冷气泄漏的通道， 并且 由于聚氨酯材料具有较好的绝热性和粘合性， 利用聚氨酯灌注填充后的冷藏 车车厢具有较好的密封性和保温性。
作为改进， 步骤 B中， 将车厢组装起来后， 在左侧板与顶板、 底板的接 合处增加内、 外包边， 右侧板与顶板、 底板的接合处增加内、 外包边， 前板 与顶板、 底板的接合处增加内、 外包边。 内、 外包边的增加不但可以加强厢 板之间的连接强度， 而且可以防止因为灌注槽内的聚氨酯发泡膨胀而损坏车 厢密封结构。
作为改进， 完成步骤 C后， 在前板与左侧板、 右侧板的接合处增加内、 外包边。 内、 夕卜包边的增加不但可以加强厢板之间的连接强度， 而且可以防 止因为灌注槽内的聚氨酯发泡膨胀而损坏车厢密封结构。
作为改进， 内包边和外包边为铝型材且依靠螺栓或铆接紧固于左侧板、 右侧板、 顶板、 底板或前板上。 利用螺栓或铆接将内外包边紧固在厢板上， 进一步的加强了厢板之间的连接强度。
作为改进， 所述步骤 C和 D中， 以高压方式向灌注槽灌入高密度聚氨酯 发泡料。 高密度的聚氨酯材料比一般的聚氨酯材料在绝热性和粘合性方面更 为突出， 并且以高压方式将其灌注入灌注槽中， 可使得灌注槽内的聚氨酯发 泡材料更好的与厢板结合， 完全消除了厢板之间的间隙。
本发明与现有技术相比所带来的有益效果是：
结构方面， 在厢板相互接合处仅使用了内外包边作为固定连接装置， 结 构简单。 接缝处被聚氨酯材料完全填满， 厢板间实现了保温层无缝隙连接， 阻断了连接处的冷气泄漏通道， 有效减少冷能的损耗， 厢体密封性能和保温 性能均获得提升。
制造工艺方面， 灌注槽结构简单， 可在厢板发泡的时候直接成型， 无需 额外的工序操作， 灌注作业简单快捷。 聚氨酯之间良好的粘接性将各厢板连 成一个整体， 并将铆钉紧固间隙胀紧无松动， 使得厢体整体的刚度和连接强 度都有所增加。 附图说明

D. 再向处于竖直方向的灌注槽 7灌注， 在灌注前， 在前板 4与左侧板 5、 右侧板 6的接合处增加内包边 9、 夕卜包边 8。
从左侧板 5与前板 4之间的缺口形成的灌注槽 7顶部高压灌入高密度 聚氨酯发泡料，
从右侧板 6与前板 4之间的缺口形成的灌注槽 7顶部高压灌入高密度 聚氨酯发泡料。
E. 将后门板安装在后门框 11上。
由于相互接合的厢板之间釆用了内、 外包边作为固定和连接， 且在车厢 整体框架中，利用后门框 11作为车厢尺寸的限制，从而使得灌注槽 Ί内发泡 的聚氨酯材料不会发泡膨胀而破坏车厢的整体结构。
本发明的实施例中的缺口形状为矩形， 也可以为三角形、 弧形、 菱形等 形状，凡具有本发明结构且只是作形式上修改的，均属于本发明的保护范畴。
本发明结构简单， 灌注槽 7在厢板发泡的时候直接成型， 无需额外的工 序操作。 接缝处被聚氨酯材料完全填满， 厢板间实现无缝隙连接， 阻断了接 缝处的冷气泄漏通道， 有效减少冷能的损耗， 提升厢体保温性能。 操作工艺 简便， 高压灌注发泡将各厢板的接合处填满，并将铆钉紧固间隙胀紧无松动， 聚氨酯之间可形成良好的粘接，使得厢体整体的刚度和连接强度都有所增加。
