具体实施方式
为了能够更清楚地理解本发明的上述目的、特征和优点，下面结合附图和具体实施方式对本发明进行进一步的详细描述。需要说明的是，在不冲突的情况下，本申请的实施例及实施例中的特征可以相互结合。
在下面的描述中阐述了很多具体细节以便于充分理解本发明还可以采用其他不同于在此描述的其他方式来实施，因此，本发明的保护范围并不限于下面公开的具体实施例的限制。
如图1所示一种低温智能存取二级库，用于物品的存储与取放，包括：
库体1，用于物品的存放，通过墙体围成一工作空间，并由墙体将工作空间分隔为存储区11以及中转区12，存储区11占用空间较大，中转区12占用空间较小，在所述的墙体上设置若干中转门体13，根据实际占地面积进行设置，可以是一扇、两扇、三扇甚至更多扇中转门体13，在中转门体13的顶部为风帘17，在中转门体13打开时风帘17开启用于隔绝存储区11与中转区12的温差，存储区11内设置若干货架4，货架4上根据类别堆放物品；在所述的存储区11内设置制冷装置16，在所述的中转区12上设置出货门体14，所述的出货门体14连通中转区12内部与库体1外部；同时，可在出货门体14上设置一个小门15用来专门传递物品，小门15的主要功能是保证中转区12内部的温度，而需要人工维护时打开出货门体14进入即可。
如图4与图5所示货架4由若干型材与连接件48拼接组合而成，若干所述的型材包括若干X轴向杆46、若干Y轴向杆47以及若干Z轴向杆43，若干所述的X轴向杆46与Y轴向杆47拼接组合成顶部框架42以及底部框架41，所述的顶部框架42与底部框架41之间通过若干Z轴向杆43支撑，若干所述的Z轴向杆43之间设置放料平台，在货架4外围的Z轴向杆43通过支撑杆45进行固定支撑；所述的顶部框架42与底部框架41结构相同包括若干平行设置的X轴向杆46、若干垂直设置于X轴向杆46上的Y轴向杆47，所述的Z轴向杆43设置在Y轴向杆47上且与Y轴向杆47垂直，所述的X轴向杆46与Y轴向杆43之间、Y轴向杆47与Z轴向杆43之间均通过连接件48固定；所述的X轴向杆46、Y轴向杆47以及Z轴向杆43均为一整根型材，即在X轴向、Y轴向以及Z轴向的同一安装位置为一整根型材；一整根型材在低温下只会出现轴向的变形，故不会出现上下错位的现象出现。
如图6所示X轴向杆46、Y轴向杆47以及Z轴向杆43之间的连接件48包括两个相互垂直的固定板481、设置于固定板481上的固定孔以及位于两个固定板481之间的加强筋482，所述固定板481通过螺栓穿过固定孔将相邻的型材连接，固定孔为圆孔或者腰孔，单个固定板481上平行设置两个圆孔或者腰孔，通过螺栓并结合型材上的T型槽进行固定，可以方便在型材的任何位置进行固定，可以根据货物的大小调整单个位置的空间大小；X轴向杆46与Y轴向杆47连接处通过两侧设置连接件48提高稳定性，Y轴向杆47与Z轴向杆43连接处通过两侧设置的连接件48提高稳定性。
基于上述结构，当采用自动存取时，为了存取机构3提高存取的效率，在存取机构3运动轨迹的两侧均设置货架4，为了保证两侧货架4的稳定性，将两侧货架4组合成为货架的组合结构，该结构通过一整根型材连接起来，更加稳定；也可以根据上述结构，两个货架4的顶部框架42以及底部框架41均采用同一个顶部框架42以及底部框架41，可以根据需要将多个货架4通过同一顶部框架42以及底部框架41组合而成。
如图7与图8所示放料平台包括安装于货架4上的托板44以及设置在托板44上的托盘410，所述的货架4采用型材拼接而成，托板44根据需要设计为多个，所述的托板44上设置若干向上的第一凸起445，所述的托盘410由若干第一凸起445支撑并与托板44上表面不接触；第一凸起445将托盘410完全托起使得在低温冷库内不会出现大面积的冻结，存取机构在取托盘410时，很容易取下。托板44可以有多种形式，例如连接在货架4两侧的一体化托板，也可以是分体式托板，在本案中为了方便存取机构3的取放，采用分体式托板进行工作，托板44包括左托板与右托板，两者结构相同，但是在安装时需要对称安装；上述的左托板及右托板包括与货架4固定的竖板441、支撑托盘410的横板442以及连接竖板441与横板442的第一斜板443，第一凸起445设置在横板442的上表面；第一斜板443根据需要设计其角度值，该角度值为第一斜板443与竖板441之间的角度值；当托盘410较浅时，其角度值设计较大，使得横板442靠在上部，可以在货架4的同一竖直方向上设置较多的托板44与托盘410组合，能够很好的提升空间的利用率；而当托盘410较深时，其角度值设计较小，可以设计为L型；而在本案中，托盘410的深度适中，故将第一斜板443与竖板441之间的夹角设计为17°，在这个角度内可以很好的利用货架4空间；竖板441的作用主要与货架4进行固定连接，货架4与竖板441之间通过螺栓连接，所述的螺栓为T字型螺栓444，在所述的托板44上开设固定孔并利用所述型材上的T型槽通过T字型螺栓444固定，通过T型槽与T字型螺栓444的配合，能够很方便对托板44的位置进行调整。
为了再次降低冻结面积，可以根据需要对第一凸起445进行设计，第一凸起445主要有两种形式，第一种为条状凸起，可以平行设置在横板442表面，也可以纵横交错的设置，同时保证条状凸起的横截面为下宽上窄的梯形结构，托盘410直接放置在梯形窄面上；第二种为点状凸起，其阵列排布在横板442表面上，其横截面也为下宽上窄的梯形结构，点状凸起相较于条状凸起更进一步的减小冻结面积。基于上述的条状凸起或者点状凸起，在其梯形的窄面上设置弧形面，用于进一步减少托板44与托盘410接触面积，同时弧形面也不会对托盘410造成伤害。
托盘410主要目的用于盛放物品，托盘410由四个侧板及一个底板组成，所述的四个侧板与一个底板之间形成 容纳腔；进一步为了方便与托板44的第一斜板443配合，侧板由上部挡板以及下部第二斜板组成，所述的第一斜板443与第二斜板倾斜的角度相同，并且在侧板与底板的过渡区设计为圆角；进一步为了实现对相应物品进行定位，在所述的底板上设置若干向上的第二凸起411。
如图2与图3所示移动机构用于将物品在中转区12及存储区11之间转运，在所述的存储区11内与所述中转门体13对应地面上设置第一轨道21，在所述的中转区12内设置第二轨道22，所述的第一轨道21与第二轨道22垂直，在所述的第二轨道22上设置可与第一轨道21连接的连接轨道23，所述的货架4设置在第一轨道21旁；连接轨道23包括设置于第二轨道22上的连接板231、设置于连接板231上的连接滑轨232、设置于连接滑轨232上的移动板233、设置在移动板233上的移动导轨234以及驱动移动板233运动的连接电机，所述的移动导轨234滑动可与第一轨道21连通；所述的连接板231在第二轨道22上滑动，其滑动的动力通过第二驱动电机提供，驱动的方式可以为齿轮与齿条结构；在第一轨道21端部伸出两个定位销235，在移动导轨234端部设置两个定位孔，定位孔与定位销235配合，能够保证第一轨道21与移动导轨234的对齐，保证存取机构3顺利移动导轨234及第一轨道21上运动。
如图9～图17所示存取机构3用于将物品从货架4上存放或者取出，所述的存取机构3包括存取框架31、设置于存取框架31底部的行走组件、设置于存取框架31上的第一提升组件32，在所述的第一提升组件32上设置第二提升组件33，在所述的第二提升组件33上设置用于存取物品的存取组件34，所述的第二提升组件33随着第一提升组件32的运动实现上升或下降，所述的存取组件34随着第二提升组件33的运动实现上升或下降；所述的存取组件34实现对物品的水平移动；在存储物品时，首先将物品放置在存取组件34上，行走组件驱动存取机构3运动到指定位置后，此时若物品在货架4上存放的位置较低时，只需要第一提升组件32运动到所需位置，控制存取组件34伸出将物品放置在货架4上即可；若物品在货架4上存放的位置较高时，首先控制第一提升组件32运动使得第二提升组件33以及存取组件34运动到第一提升组件32的最顶端，第二提升组件33开始运动带着存取组件34继续向上运动至所需位置，存取组件34伸出将物品放置在货架4上；而在取出物品时，也是通过第一提升组件32、第二提升组件33以及存取组件34配合实现取出物品。在存储物品时，将物品移动到略高于存储位置的高度，存取组件34伸出后通过第一提升组件32或者第二提升组件33下降动作实现对物品的存储；在取出物品时，通过第一提升组件32或者第二提升组件33将存取组件34的位置移动到略低于存储位置的高度，伸出存取组件34至物品下方，之后通过第一提升组件32或者第二提升组件33向上运动使得物品脱离货架4，存取组件34收回即完成取出任务。
基于上述结构及运动方式，第一提升组件32实际使用中有两种结构形式，链轮与链条组合及齿轮与齿条组合，第一种链轮与链条组合，如图9～图11所示第一提升组件32包括设置于存取框架31上的第一链轮321、与第一链轮321配合的第一链条322以及驱动第一链轮321转动的第一提升电机324，所述的第一链轮321包括主动链轮以及从动链轮，所述的主动链轮通过第一提升电机324驱动；第二种齿轮与齿条组合，如图13～图16所示第一提升组件32包括设置于存取框架31上的第一提升齿条327、设置于第二提升组件33上的第一提升电机324、设置在第一提升电机324轴上的第一提升齿轮326，所述的第一提升齿轮326与第一提升齿条327啮合。第二提升组件33也有链轮与链条组合及齿轮与齿条组合两种结构形式，第一种链轮与链条组合，如图12所示第二提升组件33包括随着第一提升组件32运动而升高的第一提升框架323、设置于第一提升框架323上的第二链轮331、与第二链轮331配合的第二链条332以及驱动第二链轮331转动的第二提升电机334，所述的第二链轮331包括主动链轮以及从动链轮，所述的主动链轮通过第二提升电机334驱动；第二种齿轮与齿条组合，如图17所示所述的第二提升组件33包括随着第一提升组件32运动而升高的第一提升框架323、设置于第一提升框架323上的第二提升电机334、设置于第二提升电机334轴上的第二提升齿轮336以及设置于存取组件34上的第二提升齿条337，所述的第二提升齿轮336与第二提升齿条337啮合。存取组件34包括随着第二提升组件33运动而升高的第二提升框架333、设置于第二提升框架333上的第一水平导轨342、在第一水平导轨342上移动的第一存取板343以及驱动第一存取板343在第一水平导轨342上运动的存取驱动组件；存取驱动组件包括设置于第二提升框架333上的存取电机344、设置于存取电机344轴头部的存取齿轮以及固定于第一存取板上的存取齿条，所述的存取齿轮与存取齿条啮合。
链轮与链条组合式的第一提升组件32的运动，首先第一提升电机324驱动第一链轮321的主动链轮转动驱动第一链条322带动从动链轮运动，而第二提升组件33内的第一提升框架323固定在第一链条322上，随着第一链条322的运动带动第一提升框架323上升或者下降。齿轮与齿条组合式的第一提升组件32的运动，首先第一提升电机324驱动第一提升齿轮326转动，第一提升齿轮326与第一提升齿条327啮合使得第一提升齿轮326带动第二提升组件33内的第一提升框架323在第一提升齿条327上运动实现升降。
进一步，为了保证第一提升框架323运动的稳定性，在存取框架31上设置第一导轨325，第一导轨325竖向固 定，在第一提升框架323上设置第一滑块，第一滑块与第一导轨325配合可在第一导轨325上实现上下运动，上述第一导轨325与第一滑块的组合有四组，分别设置在第一提升框架323两侧；进一步，为了提高第一滑块在第一导轨325内移动的顺畅度，在第一滑块底部设置滚轮，通过滚轮与第一导轨325接触实现滚动摩擦。
链轮与链条组合式的第二提升组件33的运动，首先第二提升电机334驱动第二链轮331的主动链轮转动驱动第二链条332带动从动链轮运动，而存取组件34内的第二提升框架333固定在第二链条332上，随着第二链条332的运动带动第二提升框架333的上升或者下降。齿轮与齿条组合式的第二提升组件33的运动，首先第二提升电机334驱动第二提升齿轮336转动，第二提升齿轮336与第二提升齿条337啮合使得第二提升齿条337带动存取组件34内的第二提升框架333随着第二提升齿条337运动实现升降。
进一步，为了保证第二提升框架333运动的稳定性，在第一提升框架323上设置第二导轨335，第二导轨335竖向固定，在第二提升框架333上设置第二滑块，第二滑块与第二导轨335配合实现上下运动，同时在第二滑块的底部设置滚轮实现滚动摩擦，提高顺畅度。
存取组件34的运动，存取电机344驱动存取齿轮转动，存取齿轮驱动存取齿条带动第一存取板343实现伸出操作，第一存取板343顺着第一水平导轨342运动，实现对物品送出及收回。如图18与图19所示基于存取组件34的一次伸出结构，为了提高伸出端伸出的尺寸，故设计了二次伸出结构，二次伸出结构是基于一次伸出结构实现的，在所述的第一存取板343上设置有第二水平导轨345，在所述的第二水平导轨345上设置第二存取板346，在所述的第二存取板346的两端部各设置一驱动滚轮347，每个所述的驱动滚轮347上均设置一条驱动带348；所述的驱动带348一端部固定在第二提升框架333上，另一端部固定在第二存取板346上，其固定端均位于第二存取板346一侧；所述的驱动滚轮347通过推动驱动带348实现第二存取板346的伸出与缩回。当二次伸出结构需要伸出时，首先第一存取板343做伸出动作，而第一存取板343上伸出端一侧的驱动滚轮347推动驱动带348展开，驱动带348拉动第二存取板346伸出动作；当二次伸出结构需要缩回时，第一存取板343做缩回动作，而第二存取板346另一侧的驱动滚轮347推动另一驱动带348展开，驱动带348来动第二存取板346缩回动作；将驱动带348的位置进行设置，也可以实现两侧均能伸出的目的，该驱动带348在本案中采用链条。
为了实现存取机构3的移动，该存取机构3的移动方式可以有多种形式，在本案中主要分为两种，轨道式与滚轮式；第一种轨道式，设置于第一轨道21上的驱动齿条、设置在存取框架31底部与第一轨道21配合的驱动轮、设置于存取框架31上的第一驱动电机36以及设置于第一驱动电机36轴上的驱动齿轮37，所述的驱动齿轮37与驱动齿条啮合，第一驱动电机36带动驱动齿轮37转动，驱动齿轮37与驱动齿条的配合使得存取框架31在第一轨道21上运动，驱动轮与第一轨道21配合实现对存取机构3的导向；第二种滚轮式，包括设置于存取框架31底部的驱动轮以及驱动电机，所述的驱动电机使得驱动轮在地面上自由行走，这种方式可以在地面上任意行走提升行走的自由度。
由于该存取机构3需要在零下40°的温度下运行，采用从外部接入线路很不方便，故在所述的存取框架31上设置用于给存取机构3上的用电设备供电的电池包35，该电池包35可以给第一提升电机324、第二提升电机334、存取电机344以及驱动电机36；同时，在所述的中转区12内设置用于给电池包35充电的充电站，在本案中充电包35采用锂电池，并在锂电池外部设置保温层。
进一步为了实现对存储及取出物品的自动控制，在所述的存储区11以及中转区12内均设置信号发射器，在所述的存取机构3上设置信号接收器，所述的信号发射器与信号接收器匹配应用，所述的信号发射器通过线缆连接于设置在库体1外部的控制终端上。
该低温智能存取二级库不需要人工操作，采用机器进行智能操作即可完成存储与取出物品的动作；当需要存储物品时，存取机构3在第二轨道22上运动至出货门体14前，出货门体14上的小门15打开，此时存取机构3上的存取组件34伸出，操作人员将物品放置在存取组件34上，存取组件34检测到物品后，控制端通过位于中转区12内的信号发射器将信号传给存取机构3，存取机构3控制存取组件34缩回，小门15关闭；中转区12内的信号发射器给第二驱动电机，第二驱动电机驱动连接板231在第二轨道22上滑动，连接板231带动连接滑轨232、移动板233、移动导轨234以及移动电机滑动到指定的中转门体13处停止，控制端控制中转门体13上方的风帘17打来后打开中转门体13，之后控制移动电机驱动移动板233运动并与第一轨道21接触形成整体连接；控制端控制第一驱动电机36转动，使得存取机构3从移动导轨234上运动至第一轨道21上，在存取机构3完全穿过中转门体13后，控制端控制中转门体13及风帘17关闭，存取机构3运动至指定货架4位置，控制端通过存储区11内的信号发射器与存取机构3通讯，控制存取机构3将物品放入货架4内，存储完成之后通过控制端将存取机构3运动至中转区12待下次使用，在中转区时，存取机构3通过第二轨道22运动至充电站给锂电池充电；当需要取出物品时，控制端通过中转区12内的信号发射器发射信号控制存取机构3通过第二轨道22、风帘17、中转门体13、连接 轨道23以及第一轨道21进入存储区11，在存储区11内通过控制存取机构3内的电机将物品从货架4上取出，之后通过第一轨道21、连接轨道23、第二轨道22运输至出货门体14处，打开小门15，存取组件34将物品伸出小门15，操作人员取下物品，存取组件34缩回，存取机构3整体移动至充电站充电，等待下次任务。
综上，通过上述智能存取二级库的使用，不需要人工操作，同时通过第二提升机构实现了物品的二次升降，在不改变整体构造的形式下能够充分利用货架4顶部空间，提高存储区11存储货物的数量，并且实现了自由出入中转门体13，同时配有电池包35提供动力，适合在低温下使用。
需要强调的是：以上仅是本发明的较佳实施例而已，并非对本发明作任何形式上的限制，凡是依据本发明的技术实质对以上实施例所作的任何简单修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
