Description

支撑杆快速锁紧装置及方法、燃料组件运输容器 技术领域
本发明涉及燃料组件运输技术领域，尤其涉及一种用于燃料组件运输容器的支撑杆快速锁紧装置及方法、燃料组件运输容器。
 背景技术
燃料组件的运输通常都采用专门的燃料组件运输容器实现其运输转移等。现有的一些燃料组件运输容器在结构上包括外壳以及设置在外壳内的支撑组件，支撑组件内形成有容置腔用于容置定位燃料组件。支撑组件与外壳转动连接，从而可以转动至水平状态置于容纳在外壳内，也可以转动至竖直状态，方便取放燃料组件。
在支撑组件转动至竖直状态时，通常需要杆件支撑在支撑组件和外壳的底壳之间，将其锁定在所处状态。现有的杆件进行支撑时只是通过底部抵接在外壳的下壳体上或者简单的卡合结构固定，容易出现松脱的问题，导致在取放燃料组件时支撑组件倾倒，对燃料组件来说存有较大损伤风险。另外，这种手动而非自动锁紧的操作模式需要操作员置身于支撑组件下进行，存在较大安全隐患。

为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图详细说明本发明的具体实施方式。
如图1、2所示，本发明一实施例的燃料组件运输容器，包括外壳、设置在外壳内的支撑组件2以及支撑杆快速锁紧装置。
外壳由上壳体（未图示）和下壳体1上下相互配合形成，整体为柱状结构。支撑组件2内具有容置腔，用于装载并固定燃料组件。支撑组件2主要以其一端可转动设置在外壳的下壳体1内，从而支撑组件2整体可相对下壳体1转动，形成竖直状态（垂直或者倾斜）或水平状态。支撑组件2处于竖直状态时，方便将燃料组件吊装进入容置腔或者从容置腔中吊起取出。支撑组件2处于水平状态时，整体收容于下壳体1内，通过上壳体盖合密封在下壳体1上，将支撑组件2密封在外壳内。
支撑杆快速锁紧装置设置在下壳体1和支撑组件2之间，对支撑组件2起到支撑定位的作用。在支撑组件2相对下壳体1竖直时，支撑杆快速锁紧装置对其进行支撑定位，使其可以维持在竖直状态。在支撑杆快速锁紧装置解除支撑时，支撑组件2可转动至水平收容到下壳体1中。
如图1-3所示，本发明中，支撑杆快速锁紧装置可包括导轨10、支撑杆20以及挂钩30。导轨10设置在下壳体1中，其延伸方向与下壳体1的长度方向一致。支撑杆20包括相对的第一端和第二端；第一端与导轨10活动配合，相对导轨10可转动并可沿导轨10在其长度方向上来回滑动，与导轨10相平行或夹角相接。支撑杆20的该第一端设有与挂钩30配合的滚轴。支撑杆20的第二端与支撑组件2可转动连接，在支撑杆20与导轨10呈夹角或平行状态时，支撑杆20和支撑组件2之间也相对呈夹角或平行。
挂钩30位于导轨10的第一端处并可在一第一位置和一第二位置之间来回转动。 在第一位置，挂钩30的钩部31挂接在支撑杆20的滚轴21上，将支撑杆20锁紧，限制支撑杆20沿导轨10滑动。在第二位置，挂钩30的钩部31远离支撑杆20的滚轴21，对支撑杆20解锁，支撑杆20可沿导轨10滑动。
具体地，本实施例中，导轨10采用槽钢制成，内部具有滑动槽11用于支撑杆20在其中来回滑动。滑动槽11的开放侧位于导轨10的顶部，支撑杆20的第一端从导轨10的上方通过开放侧配合滑动槽11中。
滚轴21横向穿设在支撑杆20的第一端端部，支撑杆20和滚轴21可相对转动。滚轴21的端部设有滚轮22，滚轮22配合在导轨10的滑动槽11内，支撑杆20通过滚轮22在滑动槽11内滚动相对导轨10来回滑动。在支撑杆20的第一端沿着导轨10滑动至导轨10的第二端后，支撑杆20可相对导轨10转动至与导轨10相平行，进一步可整体嵌入滑动槽11内。
挂钩30可包括相连接的杆部32和钩部31。杆部32通过第一支架可转动地连接在导轨10的第一端的端部处；钩部31位于导轨10的第一端的端部内侧，相对导轨10可顺时针或逆时针转动在第一位置和第二位置之间来回转动。
其中，如图2中所示，第一支架可包括至少一个连接板33，连接板33配合在杆部32位于导轨10外的一端上，与杆部32通过转轴34连接，与导轨10相对固定连接，从而杆部32可通过转轴34相对连接板33和导轨10转动。
钩部31连接在杆部32伸进导轨10内的端部上且朝向支撑杆20。本实施例中，如图3、4所示，挂钩30相对导轨10转动，使得钩部31相对支撑杆20上下转动。当挂钩30整体顺时针转动时，钩部31相对支撑杆20向下转动时脱离支撑杆20的滚轴21，解除了对支撑杆20的锁紧，支撑杆20可从导轨10第一端滑动至其第二端，如图4中（a）至（c）所示。当挂钩30整体逆时针转动时，钩部31相对支撑杆20向上转动时至挂接到支撑杆20的滚轴21上，将支撑杆20锁紧在其当下位置，如图4中（b）至（a）所示。
进一步地，钩部31的与杆部32相背的端面设有导向面33，该导向面33与滚轴21可相对滑动配合。支撑杆20沿导轨10滑动至导轨10的第一端时，滚轴21抵接并沿着导向面33滑动，驱使挂钩30从所在的第一位置转动至第二位置，如图4中（c）至（b）所示。在滚轴21越过导向面33，挂钩30从第二位置转动至第一位置，带动钩部31挂接到滚轴21上，将支撑杆20锁紧在导轨10的第一端处，如图4中（b）至（a）所示。
对应挂钩30，导轨10的第一端端部处设有缺口12，挂钩30位于缺口12处。从而挂钩30转动时，钩部31可通过缺口12相对导轨10上下转动，靠近或远离支撑杆20。
进一步地，本发明的支撑杆快速锁紧装置还包括锁紧机构40。锁紧机构40对应挂钩30设置在导轨10的第一端处并与挂钩30连接，驱使挂钩30在第一位置和第二位置之间来回转动。
当支撑杆20处于导轨10的第一端且挂钩30处于第一位置时，锁紧机构40通过向上的力驱使挂钩30的钩部31维持挂接在滚轴21上。当锁紧机构40通过向下的力带动挂钩30转动时，挂钩30从第一位置转动至第二位置，进而带动钩部31脱离滚轴21。
如图2、3所示，锁紧机构40可包括与支撑杆20相对并连接在导轨10的第一端上的第二支架41、设置在第二支架41上的拉杆42以及弹性件43。
第二支架41可通过紧固连接或焊接等方式固定在导轨10上，其与导轨10之间具有一空间用于容置拉杆42和弹性件43。本实施例中，该第二支架呈U形结构，以开放侧连接在导轨10上并与导轨10的缺口12相连通。
拉杆42的一端与挂钩30通过轴件实现转动连接，相对的另一端穿出第二支架41。拉杆42的位于第二支架41外的端部可作为手拉部，用于操作拉杆42。弹性件43的两端分别抵接挂钩30和第二支架41的内壁面，在挂钩30转动至第二位置后，可通过回复力驱动挂钩30转动至第一位置。
优选地，弹性件43选用弹簧，弹簧套设在拉杆42上，相对两端分别抵接挂钩30和第二支架41对应的内壁面。
另外，本发明的燃料组件运输容器还包括设置在下壳体1内的承载架3。支撑杆快速锁紧装置的导轨10固定在承载架3上。承载架3为框架结构，其相对两侧与下壳体1内的相对两侧相配合，并通过螺栓等连接件固定安装在下壳体1内。导轨10可以平行承载架3的长度设置固定在承载架3的中线位置上。导轨10以第一端朝向支撑组件2的与下壳体1的连接处。
本发明中，通过支撑杆快速锁紧装置实现对支撑杆20进行快速锁紧的支撑杆快速锁紧方法，包括对支撑杆20进行快速锁紧。
参考图4，对支撑杆20进行快速锁紧可包括以下步骤：
S1.1、支撑杆20沿着导轨10滑动至导轨10的第一端，支撑杆20上的滚轴21抵接挂钩30的钩部31并驱使钩部31向远离支撑杆20的方向转动（如图中的向下转动），此时挂钩30从第一位置转动至第二位置，如图4中（c）至（b）所示。
S1.2、滚轴21越过钩部31后，挂钩30转动带动钩部31向靠近支撑杆20的方向转动至挂接在滚轴21上，此时挂钩30从第二位置转动至第一位置，将支撑杆20锁紧，限制支撑杆20沿导轨10滑动，如图4中（b）至（c）所示。
具体地，为了将挂钩30从第一位置转动至第二位置，带动挂钩30的钩部31向下转动，利于滚轴21越过钩部31，可以下拉与钩部31连接的拉杆42，带动钩部31远离滚轴21所在的水平面，此时滚轴21及支撑杆20即可轻松滑动到钩部31朝向导轨10第一端端部的一侧。撤去拉杆42的拉力后，拉杆42受弹性件43的回复力向上移动，驱使钩部31向上转动挂接在滚轴21上，弹性件43提供弹力将钩部31维持挂接在滚轴21上。
进一步地，支撑杆快速锁紧方法还包括对支撑杆20解锁。
对支撑杆20解锁包括以下步骤：
S2.1、拉动拉杆42带动挂钩30转动，使挂钩30从第一位置转动至第二位置，带动挂钩30的钩部31脱离支撑杆20的滚轴21。
参考图4中（a）至（b），可以下拉与钩部31连接的拉杆42，带动钩部31远离滚轴21所在的水平面，使滚轴21脱离钩部31。
S2.1、支撑杆20沿导轨10向导轨10的第二端方向滑动，离开挂钩30所在位置，如图4中（c）。
结合图1及图4，燃料组件运输容器在装载燃料组件时，将上壳体从下壳体1上打开，可通过起吊设备等将下壳体1内的支撑组件2吊起至竖直状态，同时带动支撑杆20相对导轨10滑动至与导轨10的第一端并被挂钩30锁紧，具体参考上述的对支撑杆20进行快速锁紧步骤。
支撑杆20锁紧后，打开支撑组件2顶部的开口，将燃料组件垂直吊入支撑组件2的容置腔中进行定位固定；完成后关闭容置腔。最后再对支撑杆20进行解锁，解锁具体参考上述的对支撑杆20解锁步骤。
解除对支撑组件2的支撑定位后，将支撑组件2转动至水平状态收容于下壳体1，盖上上壳体，将支撑组件2封闭在所形成的外壳内。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
