本申请提供一种低温储罐的内外容器连接装置及低温储罐，为使本申请的目的、技术方案及效果更加清楚、明确，以下参照附图并举实施例对本申请进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
低温储罐是用于贮存与运输低温介质的设备。参考图1和图2，低温储罐包括内容器100、外容器200和多个内外容器连接装置300。内容器100用于贮存低温介质，外容器200包覆内容器100，内容器100与外容器200之间形成真空空间。内外容器连接装置300用于连接内容器100和外容器200。多个内外容器连接装置300设置在内容器100的端部，沿内容器100的周向间隔分布，且至少两内外容器连接装置300设置在内容器100的横向轴面的上侧。内外容器连接装置300将内容器100连接支撑在外容器200中。内容器100的横向轴面为水平且穿过内容器100的轴线的平面，如图2中平面S。
参考图2至图4，低温储罐的内外容器连接装置300包括悬挂带10、第一连接组件20和第二连接组件30。
悬挂带10的一端与第一连接组件20可转动连接，另一端与第二连接组件30可转动连接。当内容器100因热胀冷缩发生位移时，转动连接的悬挂带10可分散减少内容器100位移对悬挂带10拉扯力，减少悬挂带10的损坏的可能性。
悬挂带10的材质为纤维增强树脂复合材料。纤维增强树脂复合材料中的纤维可以为碳纤维、芳纶纤维或玻璃纤维。树脂可以为环氧树脂、聚酰胺树脂或高密度聚乙烯树脂。由于纤维增强树脂复合材料的导热性较低，悬挂带10导热系数小，且耐低温、抗疲劳，可靠性高。
低温储罐存储的低温介质一般不低于液氮的-196℃，而超低温介质温度达到-253℃以下，其中液氢、液氦介质具有沸点低、密度小、气化潜热小的特点，对容器的保温要求更为严苛。以相同结构容器为例，装液氢的标态漏热量是液氮的1.16倍，静态蒸发率是5.87倍。低温储罐的保温漏热主要有三方面：内外容器200支撑漏热、绝热被漏热、管道漏热。本申请中的悬挂带10采用纤维增强树脂复合材料，导热系数小，可有效降低内外容器连接装置300的支撑漏热，提高低温储罐的绝热性能。
参考图2至图4，第一连接组件20连接外容器200。第一连接组件20包括第一连接座21和第一连接件22。第一连接座21连接外容器200。第一连接座21上设置有第一限位卡座211。第一连接件22与悬挂带10的一端可转动连接。第一连接件22上设置有第一限位部221。第一限位部221配合收容于第一限位卡座211内，使第一连接件22限位在第一限位卡座211内，以限制第一连接件22以悬挂带10为旋转轴在第一连接座21上扭转，防止悬挂带10因扭转断裂，提高内外容器连接装置300的可靠性。
参考图4和图5，第一限位卡座211内设置有限位导槽2111。第一限位部221配合收容于限位导槽2111内。通过第一限位部221与限位导槽2111的配合，对第一连接件22进行限位，限制第一连接件22以悬挂带10为旋转轴在第一连接座21上扭转，有效防止悬挂带10扭转断裂。
第一连接件22上设置有调节结构222。调节结构222带动第一限位部221沿限位导槽2111移动，用于调节第一连接件22与第二连接组件30之间的距离，并对悬挂带10施加预紧力。工作人员可通过调节结构222调节第一限位部221在限位导槽2111中的位置，从而调节第一连接件22与第二连接组件30之间的距离，以调节悬挂带10的松紧度，对悬挂带10施加预紧力，使悬挂带10处于受拉状态，便于装配。
参考图4、图5、图7至图9，调节结构222包括调节螺母2221和调节螺杆2222。调节螺杆2222凸伸第一连接件22设置，并穿设限位导槽2111设置。调节螺杆2222与调节螺母2221配合，使得调节螺杆2222能够带动第一限位部221沿限位导槽2111移动，调节第一连接件22与第二连接组件30之间的距离，并对悬挂带10施加预紧力。
具体为，当调节螺母2221与调节螺杆2222配合旋紧，调节螺杆2222穿过调节螺母2221，并凸伸于调节螺母2221，缩短第一连接件22与第二连接组件30之间的距离，使得悬挂带10收紧；当调节螺母2221往反方向旋转，调节螺杆2222往反方向缩回，增加第一连接件22与第二连接组件30之间的距离，使得悬挂带10由收紧状态转变为松弛状态。限位导槽2111对第一限位部221起限位防扭转的同时，在调节螺杆2222的凸伸和缩回过程中起移动导向作用。
本实施例中，第一限位卡座211内凸设有锁止凸起2112。第一连接件22上设置有锁止台223。调节第一连接件22与第二连接组件30之间的距离最大时，锁止台223与锁止凸起2112抵靠。锁止台223与锁止凸起2112抵靠，对第一连接件22与第二连接组件30之间的最大距离进行限制，以免过度拉扯悬挂带10，进一步提高内外容器连接装置300的可靠性。
其中，限位导槽2111设置在锁止凸起2112上，调节螺杆2222穿设限位导槽2111。锁止凸起2112相对的两侧中的一侧与锁止台223抵靠，另一侧与调节螺母2221抵靠。调节螺母2221与调节螺杆2222配合旋转，使得调节螺杆2222凸伸锁止凸起2112或回缩，调节第一限位部221在限位导槽2111中的位置。
在其他实施例中，也可以是在第一连接件22上设置第一通孔，在第一连接座21上设置多个第二通孔，调节第一连接件22上的第一通孔与不同位置上的第二孔位对齐，通过螺钉穿设第一通孔和第二通孔将第一连接件22固定，从而调节第一连接件22在限位导槽2111中的位置，调节第一连接件22与第二连接组件30之间的距离。本实施例中采用调节螺杆2222与调节螺母2221配合的方式，结构简单，操作更为方便。
参考图4至图7，第一连接座21上背向悬挂带10的一侧可设置开口212和封板213。当通过调节螺杆2222和调节螺母2221配合调节悬挂带10至合适松紧度后，通过封板213盖设开口212，使第一连接座21背向悬挂带10的一侧密封。
参考图4、图8和图9，悬挂带10为环状。第一连接组件20还包括第一销轴23。第一销轴23穿设第一连接件22设置。悬挂带10的一端套设于第一销轴23上，并可绕第一销轴23转动。第一销轴23对悬挂带10具有预紧功能。
第一连接组件20还可包括第一轴套24，悬挂带10的一端通过第一轴套24套设于第一销轴23上。第一轴套24能减少悬挂带10绕第一销轴23旋转的摩檫力，减少悬挂带10的磨损。
第一轴套24上设置有第一止挡部241和第二止挡部242。第一止挡部241和第二止挡部242沿第一销轴23的轴线方向间隔分布设置。悬挂带10的一端套设于所第一止挡部241与所述第二止挡部242之间，用于防止悬挂带10沿第一销轴23的轴线方向发生滑动，提高内外容器连接装置300的连接稳定性。
第二连接组件30包括第二连接件31和第二销轴32。第二连接件31与内容器100连接。第二销轴32穿设第二连接件31设置，且与第一销轴23平行设置。悬挂带10的另一端套设于第二销轴32轴，并可绕第二销轴32旋转。第二销轴32对悬挂带10具有预紧功能。
悬挂带10可绕第一销轴23和第二销轴32旋转的设置使得当内容器100因热胀冷缩发生位移时，悬挂带10可旋转分散减少内容器100对悬挂带10的拉扯力，降低悬挂带10断裂的可能性。
第二连接组件30还可包括第二轴套33，悬挂带10的一端通过第二轴套33套设于第
二销轴32上。第二轴套33能减少悬挂带10绕第二销轴32旋转的摩擦力，减少悬挂带10的磨损。
第二轴套33上设置第三止挡部331和第四止挡部332。第三止挡部331和第四止挡部332沿第二销轴32的轴线方向间隔分布设置。悬挂带10的另一端套设于第三止挡部331与第四止挡部332之间，用于防止悬挂带10沿第二销轴32的轴线方向发生滑动，提高内外容器连接装置300的连接稳定性。
当调节结构222的调节螺杆2222与调节螺母2221配合，带动第一限位部221在限位导槽2111内移动，调节第一连接件22与第二连接组件30之间的距离，即为调节第一销轴23与第二销轴32之间的距离，以调节悬挂带10的松紧度。
在另一实施例中，参考图10，第二连接组件30的结构可以是与第一连接组件20的结构相同。第二连接组件30还包括第二连接座。第二连接件31通过第二连接座与内容器100固定连接。第二连接座上设置有第二限位卡座。第二连接件31上设置有第二限位部311，第二限位部311配合收容于第二限位卡座内，以限制第二连接件31以悬挂带10为旋转轴在第二连接座上扭转。
本申请中，内外容器连接装置300的第一连接组件20连接外容器200，第二连接组件30连接内容器100，悬挂带10的一端与第一连接组件20的第一连接件22可转动连接，另一端与第二连接组件30可转动连接，第一连接件22上的第一限位部221配合收容于第一连接座21的第一限位卡座211内，对第一连接件22进行限位，限制第一连接件22以悬挂带10为旋转轴在第一连接座21上发生扭转，从而防止悬挂带10发生扭转断裂，提高内外容器连接装置300及其低温储罐的可靠性高，且悬挂带10的两端分别可转动连接于第一连接组件20和第二连接组件30，在内容器100因热胀冷缩发生位移时，悬挂带10可相对第一连接组件20和第二连接组件30转动，减少内容器100位移对悬挂带10的作用力，有效防止悬挂带10断裂，提高内外容器连接装置300及低温储罐的可靠性。
