Description

一种端门翻转收容机构及可折叠的集装箱 技术领域
本发明涉及物流运输领域，尤其涉及一种端门翻转收容机构及可折叠的集装箱。
背景技术
由于地区经济发展的差异，世界范围内的国际贸易和海运存在严重不平衡性，其中亚洲、北美航线和亚欧航线表现尤为显著。这种不平衡性导致大量空箱在世界范围内流转。20世纪70年代，Sea Container公司以及Fallpac AB公司和Brasco Technik公司先后推出了折叠式集装箱，但均止步于样箱或小批量生产，未投入广泛使用。据欧盟统计，2005年-2009年间，全球海运集装箱中超过20％为空箱，陆运集装箱中约40％为空箱，另据有关公司调查，在集装箱的使用过程中，空箱闲置和调运时间约占56％，为解决空箱调运问题，航运公司不得不耗费大量人力、物力；2008年全球航运公司用于空箱调运的费用高达约330亿美元。为降低因空箱闲置和调运而增加的成本，业内开始研发折叠式集装箱。
SIO集装箱是由瑞士SIO Container公司研发的20英尺折叠式干货集装箱，由7块可拆卸的部件组成，其空箱质量比普通集装箱的空箱质量重，拆卸后6个箱子的堆叠体积与一个普通箱子体积相当。除门端部件通过铰链连接外，其他部件均依靠锁定机构固定，由3名操作人员在一台叉车或辅助定位工装配合下进行拆卸和组装。
Fallpac集装箱的折叠方法是，首先拆卸顶板，然后将短板和侧板向底板方向折叠，最后盖上顶板，2名工人在一台叉车的配合下折叠或组装，主要应用于铁路运输，虽未发现明显的技术问题或严重的设计缺陷，但由于空箱质量较重，运输和吊装效率低下，导致难以推广应用。
Cargoshell集装箱采用复合材料，空箱质量比欧通集装箱的空箱质量轻25％，箱体不干扰电子信号，有利于在箱内安装全球定位系统等电子设备。生产过程中CO 2排放量仅为普通集装箱生产过程中CO 2排放量的1/3。箱体无需喷漆，能够有效减少因喷漆造成的环境污染，箱体绝缘且耐腐蚀，维护成本较低，折叠后的高度仅为展开状态下高度的1/4。门的设计也由最初的卷帘门改为与普通集装箱一样的对开门结构。在实施折叠、展开操作时，可从集装箱顶板中部单点起吊，从而避免顶板弯曲变形。
Foltainer集装箱也是20英尺折叠式干货集装箱，折叠后的高度为展开状态下高度的1/3。Foltainer集装箱与Cargoshell集装箱类似，两者的侧板均以X形向内折叠，不同的是，Foltainer集装箱的前后端部绕门槛或前端下两处铰链向内折叠，且底部装有弹簧，能够减小折叠和展开过程中的冲击力。Foltainer集装箱折叠时，外门框的外立柱随侧板折叠， 内门框的内角柱随门板部件折叠，箱体展开后，外门框的门楣上梁与内门框的门楣下梁采用小锁杆连接，从而使内外门框连在一起。此外门段铰链采用特殊设计，单一门扇装有两排铰链，2排铰链之间通过连接板连接，使门扇绕两套翻转轴翻转，开门角度可达270度。
综上可以看出，对于可折叠的集装箱，如何设置其折叠或拆装方式以及可折叠或拆卸结构以及收容方式和结构，特别是门，极大制约了集装箱的折叠方式和折叠效果，以及装卸作业的操作性。

具体实施方式
下面结合说明书附图对本发明的可折叠集装箱1的较佳的实施方式详细描述如下， 然而除了这些详细描述外，本发明还可以具有其他实施方式。
如图1-25所示，本发明采用的技术方案为，一种可折叠的集装箱1，包括箱顶10、箱底20、两个相对设置的侧壁30和两个相对设置的端门40，箱底20上设置有用于容置端门40的收容部，箱顶10和箱底20分别与侧壁30的上端和下端铰接形成可装卸空间，端门40可完全打开地收容于所述收容部内形成装卸口；箱底20包括箱底面板201和箱底框架202，所述收容部设置于箱底面板201下，其中侧壁30包括左侧壁和右侧壁，左侧壁和右侧壁均包括上下铰接的上侧壁301和下侧壁302，端门40包括前端门和后端门，前端门和后端门均包括上下铰接的上端门401和下端门402，当集装箱1呈折叠状时，左侧壁和右侧壁分别向内折叠收容于箱顶10和箱底20之间，端门40收容于所述收容部内，集装箱1还包括用于锁止上侧壁301和下侧壁302使保持在同一平面内不发生相对运动的侧壁锁止机构304和用于在端门40同时垂直于箱底20和侧壁30时将端门40和侧壁30进行锁止的端门锁止机构403。
其中所述箱顶10包括箱顶面板104和箱顶框架103，所述侧壁30包括侧壁面板306和侧壁框架305，所述端门40包括端门面板408和端门框架409。
进而为了更好地减轻人工作业时的人力，便于人力作业的可折叠的集装箱1，其中箱顶面板104、侧壁面板306和端门面板408均采用玻纤蜂窝板材质，箱底面板201采用玻纤蜂窝板材质上附花纹铝板材质；箱顶框架103、侧壁框架305和端门框架409均采用铝合金材质；箱底框架202采用钢制材质。使集装箱1整体重量轻且具有相当的强度，更方便人工操作和使用。
同时箱底框架202上设置有标准的叉孔2024，用于装卸前后对集装箱1进行移动，更进一步地，集装箱1还设置有用于折叠后进行叠置的定位结构，所述定位结构包括设置于所述箱顶10上的堆垛角101和设置于所述箱底20上的叠置凹孔，避免叠置后的集装箱1相互之间滑动。同时优选地，所述箱底框架202的四角或对角上凸出所述箱底面板201设置有第一限位部2023，所述第一限位部2023设置于所述箱底面板201的外侧，所述第一限位部2023凸出所述箱底面板201的高度小于或等于所述箱顶10厚度和所述左侧壁30折叠后的厚度之和。用于侧壁30展开时限制所述下侧壁302向外翻转，集装箱1呈折叠状态时对所述箱底面板201上的折叠结构进行适当限位。所述下侧壁302上也可以设置有第二限位部309，所述第二限位部309设置于所述容纳空间的外侧，用于限制所述上侧壁301展开时向外翻转。
优选地，端门40的高度大于侧壁30的高度且小于侧壁30的长度。更为具体地，下端门402的高度大于上端门401的高度，所述端门40包括位于所述侧壁30最低端下方 的延伸段，所述延伸段位于所述箱底面板201的上表面之下，所述延伸段为下端门402的端门框架409的一部分，所述延伸段上设置有与所述叉孔2024对应的开口。
更优选地，所述侧壁30的长宽高与运输装置的承载部或集装箱1的长宽高相匹配，所述端门40的高度小于所述侧壁30的长度，所述箱底20的高度为所述集装箱1高度的1/9到1/8之间，所述集装箱1呈折叠状时的高度为所述集装箱1展开完成后的高的1/6到1/7之间。最优选地，所述侧壁30的长宽高与运输装置的承载部或集装箱1的长宽高相匹配，可以制成人力可操作的单元化的集装箱1尺寸，若干并排或单独放置于运载装置或集装箱1的长度或宽度方向上，所述端门40的高度小于所述侧壁30的长度，所述箱底20的高度为所述集装箱1高度的1/9到1/8之间，所述集装箱1呈折叠状时的高度为所述集装箱1组立完成后的高的1/6到1/7之间。
更优选地，所述集装箱1的长宽高适用于拖车宽度尺寸，所述折叠箱的外尺寸长、宽、高分别为2200毫米、2550毫米、2400毫米，所述箱底20高度为280-400毫米，所述箱顶10、所述侧壁30、所述端门40厚度为45-55毫米，所述折叠箱折叠完成后350-400毫米。具体地，所述集装箱1的长宽高适用于拖车宽度尺寸，所述折叠箱的外尺寸长、宽、高分别为2200毫米、2550毫米、2400毫米，所述箱底20高度为280-400毫米，所述箱顶10、所述侧壁30、所述端门40厚度为45-55毫米，所述箱顶面板104、所述侧壁面板306、所述端门面板408的厚度为15-25毫米，所述折叠箱折叠完成后350-400毫米。
其中所述收容部，也即用于容置端门40的端门收容结构，设置于箱底20上，所述收容部设置于箱底面板201的下方。所述收容部包括与箱底框架202固定连接的支撑架2021，所述支撑架2021的左右两侧设置有滑道2022，所述端门40沿所述滑道2022向内运动收容于所述收容部内。所述支撑架2021靠近滑道2022的端部设置的支撑部20211，该支撑部20211也有助于端门40与侧壁30锁止后，使端门40的底部更稳固地支撑而避免晃动，支撑部20211与限位槽20223的中心的距离大于所述支撑部20211到限位槽20223的中心的距离，避免端门40的底部旋转时产生干涉。
优选地，当需要描述限制端门40使其不脱离箱底20翻转时，可以描述为端门40的左右两侧靠近端门40的侧壁30底端位置处固定设置有限位块组件或限位块；当需要描述为了方便端门40在收容部内顺畅滑动时，可以描述为端门40的左右两侧靠近端门40的侧壁30底端位置处固定设置有滑块组件或滑块，滚轮组件或球形滚轮，或者滚轮组件或者圆柱形的滚轮；当需要可以描述为了方便端门40在收容部内顺畅滑动时同时限制端门40使其不脱离箱底20且能使端门40不脱离箱底20更顺畅地翻转时滚轮组件或滚轮，或者滚轮组件或者圆柱形的滚轮。根据描述场景的不同，可以择一地对应地进行相应描述。 和最优选的圆柱形滚轮相比，其相同之处在于安装位置相同，不同之处在于所实现的功能相同或部分相同，而实现功能的运动形式或运动效果在不同场景下较差而已。
比如，滑块通过固定轴4042与端门40固定连接，所述滑块设置于所述滑道2022上，端门40通过滑块沿滑道2022运动。滑块有助于在滑道上方便移动，滑块可在限位槽20223内转动也相当限位块，只要限位槽20223能限制滑块不脱离箱底20且在限位槽20223中有足够的空间供其带动端门40翻转即可。因此限位组件和滑块组件可依据本发明去可实现滚轮组件的功能，只是效果上较差而已。
更进一步地，为了实现端门40的折叠收容并且端门40不脱离箱底20进行翻转展开，本发明的优选的端门翻转收容机构，所述滑道2022的端部设置有用于限制所述滑块滑动的限位槽20223，所述限位槽20223的槽底低于所述滑道2022，所述限位槽20223的内侧槽壁与所述滑道2022平滑过渡，端门40通过所述滑块沿所述滑道2022运动，通过所述滑块限位于所述限位槽20223内使端门40绕所述滑块在水平位置和竖直位置之间翻转。所述滑道2022的端部设置有用于对端门40进行限位的限位槽20223，所述限位槽20223的槽底低于所述滑道2022，所述限位槽20223的开口侧端门40与所述滑道2022平滑过渡，所述限位槽20223的另一侧端门40高于所述滑道2022，集装箱1展开时，所述端门40限位于所述限位槽20223内而不脱离于箱底20，端门40绕所述滑块由水平位置向竖直位置翻转到位。
优选地，所述限位槽20223和所述滑道2022设置于箱底框架202上，端门40垂直于箱底20时，端门框架409位于侧壁框架305之间。
当然一种优选实施例为，所述滑道2022也可以平行设置为两组，所述收容部内上下平行设置有两组滑道2022，所述前端门和所述后端门上下平行设置于所述收容部内。所述前端门和所述后端门也可以为一整体或折叠形式，直接收容于所述收容部内。但这样会造成前端门和后端门的展开和折叠需要较大的操作空间，其中折叠形式的会相对减少操作空间，而且两个滑道2022之间需要避免前端门和后端门收容干涉的间隙。所述可折叠的集装箱1折叠后的高度尺寸有所增加。而且两个滑道2022仅在一端设置有限位槽20223，但这样相应地，两个端门40的高度特别是端门框架409的高度就不相同。
另一种也是最优的实施例为，端门40包括设置于所述箱底20两端的前端门和后端门，前端门和后端门均包括相互铰接的上端门401和下端门402，所述收容部内设置有一组滑道2022，前端门和所述后端门通过上端门401和下端门402折叠后向内运动收容至所述收容部内，上端门401和下端门402折叠后沿所述滑道2022运动，使前端门和后端门分别收容于所述收容部的前后两端。该最优实施例和其他两种实施例相比，前端门、后端 门的操作空间更小，而且可折叠的集装箱1折叠后的高度也更底，折叠效果更好。
这里的滑块组件或滑块需要同时实现在滑道2022上滑动和在限位槽20223内限位并使端门40相对于箱底20转动。当端门40需要展开时，将端门40从收容部向外拉出，使所述限位块组件设置于所述限位槽20223内，所述端门40跟随所述限位块绕所述固定轴4042的转动而相对于所述箱底20翻转至垂直于所述箱底20设置，当端门40需要收容时，所述限位块组件脱离于所述限位槽20223。
其中一种优选实施例为，所述限位块为球形滚轮，球形滚轮的中心自由旋转。一种优选实施例为，所述限位块为球形滚轮，设置于所述固定轴上，所述球形滚轮绕所述固定轴上的一点自由旋转。
一种也是最优优选实施例为，所述限位块为圆柱形的滚轮4041，设置于所述固定轴4042上，所述滚轮4041绕所述固定轴4042旋转。所述圆柱形的滚轮4041包括对称设置的第一壁和第二壁，第一壁和第二壁的中部通过滚轮4041支撑壁相连，所述滚轮4041支撑壁围成供所述固定轴4042放置的轴孔，所述滚轮4041支撑壁的外表面设置于滑道支撑部20221上，所述滑道限位部20222和所述滑道支撑部20221相对设置，用于对所述滚轮4041进行限位避免所述滚轮4041脱离所述滑道2022，且与滚轮4041支撑壁留有足够的第一间隙避免运动干涉。所述滚轮4041的外侧设置有与所述滚轮4041同轴设置于所述固定轴4042上的限位轮4043，所述滑道支撑部20221和所述滑道限位部20222与所述滑道2022靠近所述箱底外侧的一侧侧壁之间设置有第二间隙，所述间隙用于容纳所述限位轮4043。更具体地，所述限位槽20223的所述滑道2022对接，所述限位槽20223还包括用于支撑和容纳所述限位轮4043的限位轮4043容纳部。所述第二间隙内靠近所述限位槽20223处设置有用于限制所述滚轮4041旋转的限位结构，所述限位结构可以为支撑架2021的一部分。所述滚轮4041的限位轮4043落入所述限位槽20223内后，所述滚轮4041不动，所述端门40跟随所述固定轴4042绕所述固定轴4042的轴线翻转。对应最优选实施例，所述限位槽20223为C形槽，所述C形槽的槽底低于所述滑道2022，所述C形槽的内侧槽壁于与所述滑道2022平滑过渡，所述集装箱1需要折叠时，所述限位块脱离所述限位槽20223沿滑道2022运动收容于所述容纳部内。当然，如果其他实施例中的限位块，则可以通过根据本发明可习得的方式实现即可认定落入本发明的保护范围。其中所述滑道2022沿垂直于滑道2022长度方向的截面呈C形，所述限位槽20223沿平行于滑道2022长度方向的截面呈C形。所述C形槽靠近端门40的一侧与滑道2022平滑过渡，所述限位结构设置于所述限位槽20223和滑道2022的第二间隙之间。
优选地，所述限位槽20223的槽底与所述箱底框架202的最低位置处间隔一段距离 设置，用于向下按压所述端门40将所述端门40脱离所述限位槽20223。
上端门401的外侧可以设置有提手。更加有助于人工操作时的借力和人力支撑，操作更加方便。
所述锁止机构优选地，包括用于锁止上侧壁301和下侧壁302使保持在同一平面内不发生相对运动的侧壁锁止机构304和用于在端门40同时垂直于箱底20和侧壁30时将端门40和侧壁30进行锁止的端门锁止机构403。
集装箱1还包括用于将端门40和侧壁30进行锁止的端门锁止机构403，所述端门锁止机构403的至少部分凸出于端门框架409，箱底框架202上设置有用于避让所述端门锁止机构403的缺口2025。凸出部分比如端门锁止机构403的伸出状态的活动闩4031如图15所示，(也可不凸出，为缩回状态如图16所示)和第一端面辅助锁止机构的第一凸起406和第二端面辅助锁止机构的第二凸起407。

下面以最优实施例对集装箱1的折叠和展开过程进行详细说明。
可折叠的集装箱1由展开状态进行折叠时，端门锁止机构403、第一端门辅助锁止机构、第二端门辅助锁止机构和侧壁锁止机构304由锁止状态释放至解锁状态：首先，依次释放用于锁止端门40和侧壁30的端门锁止机构403、第二端门辅助锁止机构和第一端门辅助锁止机构，使端门40脱离侧壁30，将端门40绕设置于下端的圆柱形的滚轮4041(即绕固定轴4042的轴线)进行旋转，当下端门402呈水平时使上端门401放置于下端门402上，将折叠后的端门40沿滑道2022向前推动而收容于收容部内，所述前后端门40分别进行释放、折叠、滑动和收容于收容部的前后两端；然后分别依次将一侧侧壁30的侧壁锁止机构304释放，使侧壁30分别向内折叠收容于箱顶10和箱底20之间，所述左右侧壁30分别进行，箱顶10落于所述左右侧壁30之上，集装箱1折叠完毕。
可折叠的集装箱1由折叠状态展开方法如下：由两人于集装箱1的前后两端站立，并于右侧抬起箱顶10使箱顶10和该侧侧壁30的上端呈倾斜支撑，当右侧的上侧壁301和下侧壁302即将完全展开时由两人同时单手对侧壁锁止机构304进行操作，通过拉手3046将销轴3045向外拉出撤销销轴3045对上侧壁301的旋转的干涉，待右侧的侧壁30完全展开到位时释放拉手3046将销轴3045释放，实现对右侧的上侧壁301和下侧壁302的锁止，此时右侧的侧壁30和箱顶10均倾斜支撑在箱底20上；然后于左侧抬起箱顶10，使右侧的侧壁30竖直并使箱顶10抬起至水平，当左侧的上侧壁301和下侧壁302即将完全展开时由两人同时单手对侧壁锁止机构304进行操作，通过拉手3046将销轴3045向外 拉出撤销销轴3045对上侧壁301的旋转的干涉，待左侧的侧壁30完全展开到位时释放拉手3046将销轴3045释放，实现对左侧的上侧壁301和所述下侧壁302的锁止使箱顶10和左右侧壁30展开完成；进一步地，将收容于前端的呈折叠状态的前端门40抽出，同时抬起前端门40并通过设置于所述上端门401上的提手使上端门401和下端门402呈一定角度，当上端门401抬起至上端门401上的第一凸起406对应侧壁30上的第一凹槽307时通过第一端门40辅助锁止机构对端门40和侧壁30进行定位，其中第一凸起406放置于第一凹槽307内对前端门40和侧壁30进行定位，进一步通过铰链对上端门401进行角度调整使第一凸起406在第一凹槽307内运动到位，所述前端门40完全展开；进而通过第二端门40辅助锁止机构对端门40和侧壁30进行预安装，其中第二凸起407对应第二凹槽308，将第二凸起407压入第二凹槽308中对前端门40和侧壁30进行预安装；最后通过端门锁止机构403对前端门40和侧壁30进行最终锁止；最后根据前端门40展开及锁止相同方式对后端门40和侧壁30进行锁止。
优选地，还包括锁止机构，所述锁止机构包括用于锁止上侧壁301和下侧壁302使保持在同一平面内不发生相对运动的侧壁锁止机构304和用于在端门40同时垂直于箱底20和侧壁30时将端门40和侧壁30进行锁止的端门锁止机构403。
