Abstract

一种设备装卸辅助装置（3），其包括支撑架（31）和转动支架（32），该转动支架转动安装在支撑架上。在正常情况下，设备（5）放置在转动支架的底架（351）上，在转动过程中，设备会逐渐升高并倾斜转移到侧架（321）上，由侧架对设备进行支撑。由于第一转动轴线沿水平方向设置且位于设定高度上，例如设定高度可以大于或等于车尾箱的最低高度，当侧架转动到第一转动轴线所在平面后，设备已由原来的底架所在位置上升到设定高度，这样就完成了对设备的抬升，然后就能够更方便的将设备装入到车尾箱内。如要将设备从车尾箱移动到地面时，可按照以上顺序反向操作。利用该辅助装置可以更方便的装卸设备，节省人力。

 有益效果
依据上述实施例的设备装卸辅助装置，其转动支架转动安装在支撑架上。以将设备从地面装入到车尾箱为例，在正常情况下，设备放置在转动支架的底架上，此时可绕第一转动轴线向上转动转动支架及其上的设备。在转动过程中，设备会逐渐升高并倾斜转移到侧架上，由侧架对设备进行支撑。由于第一转动轴线沿水平方向设置且位于支撑架的设定高度上，例如设定高度可以大于或等于车尾箱的最低高度。当侧架转动到第一转动轴线所在平面后，设备已由原来的底架所在位置上升到设定高度，这样就完成了对设备的抬升，然后就能够更方便的将设备装入到车尾箱内。如要将设备从车尾箱移动到地面时，可按照以上顺序反向操作。利用该辅助装置可以更方便的装卸设备，节省人力。

本文中为部件所编序号本身，例如“第一”、“第二”等，仅用于区分所描述的对象，不具有任何顺序或技术含义。而本申请所说“连接”、“联接”，如无特别说明，均包括直接和间接连接（联接）。
一个实施例中，提供了一种设备装卸辅助装置，其用于装卸设备，尤其是便于在具有高度差的两个位置之间搬运设备。本实施例主要以医疗设备的装卸为例进行说明。但，很显然，该设备装卸辅助装置也可以应用在其他机械设备的装卸上。
请参考图1-3，该设备装卸辅助装置3（以下简称为辅助装置3）包括支撑架31和转动支架32。
该支撑架31用于对转动支架32进行支撑。该转动支架32包括用于在设备5处于常规位置时支撑设备5的底架351和用于在设备5倾倒时支撑设备5的侧架321。所说的常规位置是指设备5按照常规使用状态进行摆放时所处位置，此时主要由底架351对设备5进行支撑。该底架351连接到该侧架321。转动支架32转动安装在支撑架31上，并能够绕第一转动轴线转动。第一转动轴线沿水平方向设置且位于设定高度上。例如，当支撑架置于地面上时，第一转动轴线相对于地面位于设定高度处。此处第一转动轴线沿水平方向设置并不一定是沿绝对水平方向设置，还包括沿大致水平方向设置。
这里以将设备5从地面装入到车尾箱为例，请参考图1、2和4，在正常情况下，设备5放置在转动支架32的底架351上。底架351主要起到支撑设备5的作用。为了减少设备5搬运过程中的移位，可以优选使设备5的重心与第一转动轴线大致重合。
请参考图1、3和4，当需要抬升设备5时，可绕第一转动轴线向上转动转动支架32及其上的设备5。在转动过程中，设备5会逐渐升高并倾斜转移到侧架321上，由侧架321对设备5进行支撑。如图4所示，由于第一转动轴线沿水平方向设置且位于设定高度上，该设定高度与设备5需要抬升的高度有关，例如设定高度可以大于或等于车尾箱的最低高度。当侧架321转动到大致水平的位置时，设备5已由原来的底架351所在位置上升到设定高度，这样就完成了对设备5的抬升，然后就能够更方便的将设备5装入到车尾箱内。当设备5被装入到车尾箱后，还可以转动支撑架31，将其也一并收纳到车尾箱内。
请参考图5，当要将设备5从车尾箱移动到地面时，可按照以上顺序反向操作。先将支撑架31反向转动，使支撑架31接触地面或其他支撑平台，然后将转动支架32和设备5一并向下转动，最终使设备5从侧架321移动到底架351上，此时设备5与地面或其他支撑平台已经足够的近，可以很方便的将设备5从底架351上移下。
利用该辅助装置3可以更方便的装卸设备5，尤其是在两个高度不同的位置之间搬运体积庞大的设备5，可以极大的节省人力，减少随行人员的数量。基本上可以由一个人就实现整个设备5的搬运工作。
进一步地，请参考图1，一种实施例中，该转动支架32通过侧架321与支撑架31形成上述的转动安装。因为侧架321竖直设置，因此其能够更方便的与支撑架31装配，也可以简化装置的结构。
当然，在某些实施例中，支撑架31与自底架351延伸所形成的部件进行转动连接也是可行的。
该底架351和侧架321被设置为能够有效地支撑设备5，其可以是板体状结构，如底架351采用了底板的形式，也可以框架类结构，如侧架321采用了框架式侧架。
请参考图1、6和7，一种实施例中，该底架351转动安装在侧架321上，并能够绕第二转动轴线转动。该第二转动轴线沿水平方向设置且与第一转动轴线平行，可以使底架351能够翻转成与侧架321层叠收纳。当该设备装卸辅助装置3不使用时，可以如图7所示，将底架351沿第二转动轴线翻转，最终折叠到侧架321所在位置，减小整个装置的体积，以便收纳。
具体地，请参考图1和6，一种实施例中，为了实现底架351和侧架321的转动连接，该转动支架32包括铰接板352。铰接板352固定在底架351上。侧架321与铰接板352通过销轴353形成绕第二转动轴线转动的转动连接。
请继续参考图1和6，该铰接板352具有槽状的安装腔，侧架321上的支脚插入该安装腔内，该销轴353同时穿过该安装腔的两侧腔壁以及插入安装腔的侧架321的支脚，从而形成铰接。当然，该图1和6所示转动连接结构也可以通过其他形式的转动连接结构来代替。
进一步地，为了便于辅助装置3的收纳，请参考图1、6和7，一种实施例中，该转动支架32包括至少一个转动臂364。侧架321转动安装在转动臂364上，并能够绕第三转动轴线转动。第三转动轴线沿竖直方向设置。转动臂364转动安装在支撑架31，并能够绕第一转动轴线转动。
该侧架321，乃至整个转动支架32，主要通过该转动臂364来实现与支撑架31的转动连接。一种实施例中，请参考图6，该转动臂364与侧架321固定在一起，并通过螺母366、垫片367、滑环365、垫片368、螺母369与支撑架31的转轴363相连接，以保证转动支架32相对于支撑架31可以绕上述第一转动轴线顺畅的转动。
请参考图7，在采用了该转动臂364后，当辅助装置3不使用时，可以将侧架321连通底架351一起绕第三转动轴线转动，从而收纳到支撑架31上，例如收纳到支撑架31的支撑臂36上，进一步减小该辅助装置3的体积。
进一步地，请参考图1和6，一种实施例中，该底架351大致沿水平方向平铺设置，该侧架321大致沿竖直方向设置在底架351的一侧。或者，该侧架321也可以从底架351的其他位置向上延伸设置。
请参考图2，当设备5放置到底架351上后，正常情况下，设备5主要支撑在底架351上。某些情况下，此时侧架321可能也会对设备5形成一定程度的支撑。请参考图3，当转动支架32翻转时，由于侧架321设置在底架351的一侧，设备5的重心会自然转移到侧架321上，从而使侧架321对设备5进行主要支撑。
进一步地，请参考图1、4和6，一种实施例中，在底架351和侧架321的交接处设置有第一滚轮354。该第一滚轮354的转动轴线与第一转动轴线平行，使第一滚轮354在转动支架32绕第一转动轴线转动时对转动支架32形成滚动支撑。当底架351向上或向下翻转时，该第一滚轮354可以接触地面形成支撑，从而减少使用者用于使转动支架32和设备5翻转的作用力，使使用者可以利用较少的力就实现对转动支架32和设备5的翻转。
当然，在其他一些实施例中，该底架351也可以悬空设置，且底架351上与侧架321对应的一侧的外沿至第一转动轴线的垂直距离为第一距离，用于放置支撑架31的平面（如地面或其他支撑平台）至第一转动轴线的距离为第二距离，该第一距离小于第二距离，用以保证转动支架32转动时不会造成底架351上与侧架321相对应的一侧触及地面而阻碍转动。
进一步地，请参考图1、4、5和6，一种实施例中，该侧架321设置有至少一个第二滚轮324，用以在侧架321支撑设备5时对转动支架32形成滚动支撑。当转动支架32翻转到以侧架321作为设备5主要支撑结构时，该第二滚轮324可以保证侧架321及其上的设备5能够在对应平面上移动，例如在车尾箱内移动，这样可以大大节省操作者用来移动辅助装置3和设备5所施加的作用力，进一步保证该辅助装置3可以由单人进行操作。
另一方面，通常情况下，该支撑架31可以具有使整个设备装卸辅助装置3在不受外力的作用下能够稳定地放置在地面或其他平台上的结构，例如图1和8所示结构。但，在某些实施例中，该支撑架31也可以仅作为转动支架32的转动安装基础，给转动支架32的转动提供一个支撑，但并不需要支撑架31具有能够独立完成稳定放置在地面或其他支撑平台的功能，此时支撑架31可以借助操作者外力作用而保持稳定，从而完成转动支架32对设备5的搬运。例如，较为极端的说，支撑架31可能是一根或多根竖直设置的支撑柱，其本身无法竖直放置在地面或其他平台上，但可以借助操作者外力而保持稳定。
例如，请参考图1，一种实施例中，该支撑架31包括至少一个竖直设置的支撑臂36，该转动支架32以绕第一转动轴线转动的方式安装在支撑臂36上。
具体地，该转动支架32可以利用上述的转动臂364及其附加部件与支撑臂36形成转动连接。
该转动臂364可以是固定高度的结构，也可以采用能够在竖直方向升降的升降结构。
请参考图3和6，一种实施例中，该支撑臂36包括升降座361和升降柱362。升降柱362以能够沿竖直方向升降的方式活动安装在升降座361上。在升降柱362和升降座361之间设置有自锁机构，用以使升降柱362停在设定位置。该转动支架32以可转动地方式安装在升降柱362上，例如安装在固定于升降柱362的转轴363上。
请继续参考图6，该升降座361可以是中空的柱状结构，而升降柱362安装在该柱状结构内。该自锁机构在升降柱362升降过程中可以分段自动锁定，例如可以选用升降滑撑、棘轮滑撑等机构。
这种具有升降功能的支撑臂36可以在转动支架32转动过程中配合需要来改变第一转动轴线的高度，以满足某些需求。例如，当底架351转动时，底架351与侧架321对应的一侧容易触及地面，此时可以通过支撑臂36来调整底架351的位置，进而避免底架351碰撞地面而阻碍转动支架32运动。
此外，优选地，该支撑架31具备能够稳定放置于地面或其他支撑平台的结构。例如，支撑架31还包括支撑座，该支撑臂36安装在支撑座上。
请参考图1和6，该支撑座包括第一支座381和第二支座382。该第二支座382与第一支座381均分布在同一水平面上并形成支撑结构。这种支撑结构可以稳定的支撑转动支架32，而且基本无需操作者施加外力来进行辅助。第二支座382与第一支座381可以形成呈夹角的分布，例如可以是大致呈90°的夹角。
为了进一步减小辅助装置3收纳时所占空间，一种实施例还包括转接板385。第一支座381与转接板385固定连接，转接板385铰接安装在第二支座382上，并能够绕第五转动轴线转动。第五转动轴线沿竖直方向设置，使转接板385和第一支座381能够绕第五转动轴线被翻转成与第二支座382层叠收纳。
具体来说，请参考图1和6，该转接板385固定在第一支座381上，并通过转轴373与第二支座382转动连接。同时，在转接板385和第二支座382上还设有与转轴373所在位置分离的插销孔，用于安装插销372，从而使第二支座382与转接板385以及第一支座381可以固定在如图1所示位置。
进一步地，该支撑臂36可以为一个或以上，例如图1所示辅助装置3具有一个支撑臂36。当支撑臂36为两个时，一种实施例中，该两个支撑臂36可以分设在转动支架32的两侧，转动支架32同时与两个支撑臂36转动连接。
请参考图1和6，为了便于辅助装置3的移动，一种实施例中，该支撑架31包括第三滚轮391、392、393，用以使支撑架31能够移动。该第三滚轮391、392、393可以安装在第二支座382和第一支座381上，对支撑架31形成滚动支撑。
本实施例所示辅助装置3，不仅可以方便的实现设备在不同高度的两个位置之间搬运，减少对劳动力的需求，而且在不使用时还可以方便的收纳，不占据过多空间，收纳后易于携带。
一个实施例中，提供了另一种设备装卸辅助装置。
请参考图8-12，本实施例所提供的设备装卸辅助装置（以下简称为辅助装置）与实施例1所示结构的区别之一在于：
该支撑臂36采用固定高度结构，该底架351也可以悬空设置，且底架351与侧架321对应一侧的外沿至第一转动轴线的直线距离小于第一转动轴线至支撑架31放置平面（如地面或其他支撑平台）的距离，用以保证转动支架32转动时不会造成底架351上与侧架321相对应的一侧触及地面而阻碍转动。
此外，请参考图8-12，本实施例所提供的辅助装置中，转动支架32还包括自底架351倾斜向下设置的导引板352。导引板352转动连接在底架351远离侧架321的一侧，并能够绕第四转动轴线转动。第四转动轴线与第一转动轴线平行设置，使导引板352能够绕第四转动轴线被翻转成与底架351层叠收纳。设备5可以通过导引板352轻松的进出到底架351。
请参考图12，当辅助装置3被收纳时，该导引板352可绕第四转动轴线被翻转成与底架351平行。
请继续参考图10和11，本实施例所示的辅助装置中，该支撑臂36为两个时，一种实施例中，该两个支撑臂36可以分设在转动支架32的两侧，转动支架32同时与两个支撑臂36转动连接。该两个支撑臂36的设计能够保证转动支架32在相对支撑架31转动时其重心位于两个支撑臂36之间，因此具有更好的稳定性。
进一步地，不同于实施例1所示的支撑架31结构，请参考图10和11，该支撑臂36固定安装在第一支座381上，该第二支座382转动安装到第一支座381上，并能够绕第六转动轴线转动，使第二支座382能够绕第六转动轴线被翻转成与支撑臂36层叠设置。在收纳时，该第二支座382可以向上翻转，从而与底架351以及导引板352收纳到一起，进一步减小辅助装置3的体积。
进一步地，请参考图10和11，一种实施例中，该滚轮转接块483、487固定在第一支座381上，第四滚轮484、488固定在上述滚轮转接块483、487上。当辅助装置在收纳状态时，操作者可以提起辅助装置，利用第四滚轮484、488辅助装置的移动。
进一步地，请继续参考图10和11，一种实施例中，作为另一种示例，该转动臂364与侧架321固定在一起，并穿过衬套464、469，轴承462、467，轴承,461、466与支撑臂36转动连接。
 
以上应用了具体个例对本发明进行阐述，只是用于帮助理解本发明，并不用以限制本发明。对于本领域的一般技术人员，依据本发明的思想，可以对上述具体实施方式进行变化。
