现有电商与快递行业的物流分拣作业现场，通常采用分拣小车进行货物自动输送、分拣与复检等操作。载有货物的行走小车在输送线上循环输送，以实现货物的快速分拣与装卸。
如申请人在先申请的以下专利，申请号CN2019211804902，名称为组合型分拣小车，其具有设置于上部的输送组件和下部的车架组件。其中，输送组件包括有2组并列、独立设置的输送单元；在所述2组输送单元的同一侧，共同连接一风琴罩。上述一车双输送的模块化结构设计，既可同时输送、向两侧分拣2个小包裹，也可2个输送单元同时输送1个大包裹、同步地向相同一侧分拣卸载。并列设置的输送单元，与车架组件的安装连接、以及各自的电气控制是独立分开的。
伴随现场分拣作业效率的不断提升，现行通常选用的是水平环形交叉带分拣设备，或是因场地空间有限而选择成垂直方向的环形交叉带分拣系统。对此，上述在先申请具有明显的局限性，主要在于：1)整体结构复杂、重量较大，不利于提高现有交叉带分拣系统的作业效率；2)部件数量较多，制造成本较大，同时受到加工精度的限制，小车整体安装调试精度也较低；3)由于部件之间连接结构繁杂，直接影响到小车整体的运行稳定性；4)工作噪声较大，不利于改善现场的运营环境。
有鉴于此，特提出本专利申请。

具体实施方式
实施例1，如图1至图3所示，所述的交叉带分拣小车，通过两部分模块化结构相互连接而形成整体式结构，包括上部输送单元100和下部框架200。
其中，所述的上部输送单元100包括皮带托板2和连接于皮带托板2两侧的侧板5，在侧板5的两端分别轴设有无动力滚筒3和动力滚筒4，分拣皮带1缠绕于皮带托板2、无动力滚筒3和动力滚筒4之间；由动力滚筒4传递动力而带动分拣皮带1在皮带托板2上沿两个方向往复运行以实施不同的分拣动作。
在每一侧侧板5的侧向，水平地安装有折合板7、垂向地连接有第一折弯连接板8或第二折弯连接板9。
具体地，如图4所示，所述的折合板7为一整体水平的板状部件，其外侧边缘具有多均段圆弧段103。如图5所示，同一分拣小车两侧的折合板7的圆弧段103具有相互啮合的关系，即前后分拣小车相互串联时，其各自的折合板7的圆弧段103相互啮合且保留一定的间隙而可替代现有使用的风琴罩部件。形成前后分拣小车的有效连接、防止货物从分拣小车间掉落，又可避免因风琴罩被拉伸或扭曲而在小车运行过程中发出的噪声，同时又能保证提高前后小车对接处的机械强度。
在折合板7上设置有多个折合板固定孔102，结合图4和图6所示，在侧板5的侧部安装带有固定板安装孔105的多组折合板固定板6；折合板固定孔102与固定板安装孔105对接，再通过沉头螺钉104将折合板7和折合板固定板6进行固定连接。
如图6所示，折合板固定板6具有折弯部，其侧向通过螺栓与侧板5固定连接，其水平顶部通过螺栓分别贯穿折合板固定孔102、固定板安装孔105完成折合板7的水平固定。
如图2所示，在两侧的侧板5之间，横向地连接有多组拉杆10以加强由皮带托板2和侧板5构成上部输送单元100基础框架结构的稳定性。即从侧板5的外侧，通过螺栓将拉杆10的两端与侧板5进行固定连接。
第一折弯连接板8、第二折弯连接板9分别连接于一侧的侧板5，第一折弯连接板8、第二折弯连接板9的底部分别设置有用于连接下部框架200的第一安装孔108、第二安装孔101，通过螺栓将上部输送单元100和下部框架200进行稳定性连接而形成分拣小车整体。
如图3和图7所示，所述的下部框架200，具有车架11和连接于车架11的小车结合板12、至少两组走行轮组件13和导向轮组件14、以及关节轴承组件15、次级板16、电气控制盒安装件17。
其中，所述的车架11具有T型的整体式结构，包括横向部110和竖向部111；
在横向部110的外侧边缘设置有具有多段、连续的圆弧部202，圆弧部202既能改善局部应力分散而提高横向部110的抗拉伸能力，同时又可提高与竖向部111连接强度；
机架11整体为铸造部件，在横向部110和竖向部111的两侧连接处是主要的受力区域。为提高连接区域的机械强度，可采取的改进措施是，在横向部110和竖向部111之间连接有过渡部203，过渡部203通过冲压成型形成而与横向部110、竖向部111形成一体式结构。通过过渡部203，可分散、均衡横向部110、竖向部111受到的外力而辅助提高机架11整体的刚度与强度。
沿机架11的竖向部111纵向开设有长腰槽204，在长腰槽204内外侧分别设置有多组内部螺纹孔205和外侧定位孔206，通过螺栓分别从外向内贯穿螺纹孔205和外侧定位孔206而将插入长腰槽204的次级板16进行锁紧固定。
具体地，先将次级板16插入长腰槽204中，然后将螺栓穿过外侧定位孔206，则螺栓前端顶入内部螺纹孔205中，则螺栓从外向内将次级板16的内侧面压向长腰槽204的侧壁，继续紧固螺栓最终将次级板16与长腰槽204的内侧面压紧，最终实现次级板16的安装与间隙调节操作。上述安装结构与方法，既便于人员操作和提高定位准确性，而且通过简单的步骤即可完成精度要求较高的次级板16的安装调试，能够辅助提高分拣小车电气控制系统的操控准确性。
如图8所示，为进一步地提高机架11与上部输送单元100之间的连接稳定性，可在机架11的竖向部111端部安装小车结合板12。
小车结合板12是一整体焊接件，在A型的结合板本体214的两侧焊接有外翻双向的耳部300；结合板本体214前端开设有轴承圆孔210以与关节轴承组件15的轴 承件尾部轴进行固定连接；在结合板本体214的两侧设有至少两组侧部圆孔211，以与设置在机架11侧向的侧部螺纹孔207通过螺栓连接；在结合板本体214的中间连接处设置有中部圆孔212，以与机架11顶端的端部螺纹孔208通过螺栓进行连接，当机架11与小车结合板12进行连接时，此处的端部螺纹孔208起到将机架11与上部输送单元100定位与拉紧的作用；
在两侧耳部300上，分别设置有至少两组垂向圆孔213，以实现与第一折弯连接板8底部的第一安装孔108通过螺栓进行连接固定；相对应的是，在机架11的横向部110上设置有多个垂向安装孔201，以实现与第二折弯连接板9底部的第二安装孔101通过螺栓进行连接固定。
如图3和图9所示，两组走行轮组件13、导向轮组件14分别通过销轴设置于车架11的横向部110的两端，关节轴承组件15的两侧通过螺栓连接于横向部110的横向中心。
为降低分拣小车的整车重量，机架11通常为铝质铸造件，在走行轮组件13与导向轮组件14在轨道表面运行过程中，轮对组件内部的销轴与机架11会存在相互转动而形成对机架11的异常磨损。对此，本申请采取的解决措施是，在机架11内侧、销轴上套设有第一垫块215和第一防松垫圈217、第二垫块216和第二防松垫圈218，并在销轴顶端加装第一螺母219、第二螺母220。通过上述防松垫圈和螺母，可将两组垫块分别压紧于机架11内侧面上，当走行轮组件13与导向轮组件14轴心处的销轴产生轴向转动时，第一垫块215、第二垫块216会随之旋转一定的角度，随即第一垫块215、第二垫块216的外端角221会与机架11内侧壁相互挤压而卡住，此时第一垫块215、第二垫块216不能继续旋转了，从而制动走行轮组件13与导向轮组件14轴心处的销轴，使得走行轮组件13与导向轮组件14的轮对只能空转，避免了销轴与机架11之间发生异常磨损，相对地延长了铸铝材质的机架11的使用寿命。
如图1和图10所示，在机架11的竖向部111顶部安装有电气控制盒安装件17。在电气控制盒安装件17的端部设置有定位孔301，以与机架11的竖向部111上的竖向定位孔209通过螺栓进行固定连接。上述结构适用于多种电气控制盒安装方式，既可简化不同电气控制盒与机架11的安装与调试，同时又可减少拆装手续、节约调试时间。
如图11所示，所述的电气控制盒安装件17还有一种安装结构与方式，即在电气控制盒安装件17上设置有与竖向部111上的竖向定位孔209相匹配的长圆孔302，两者通过螺栓进行固定连接。
另外，在电气控制盒安装件17上还焊接有多组带有螺纹孔的小圆板303，以及位于侧部的侧面开孔304，，以实现与各类异形电气控制盒的安装与定位，待将电气控制盒全部安装到位后，再整体地实现与上述机架11的连接。
在上述结构设计的基础上，本申请实现了下述分拣小车的组装方法：
分拣小车分为上部输送单元100和下部框架200两部分，上部输送单元100和下部框架200各自独立组装后再实施整体化安装；
其中，所述的上部输送单元100，是由皮带托板2与两侧侧板5构成基础框架，在侧板5的两侧端分别轴设有无动力滚筒3和动力滚筒4，分拣皮带1缠绕于皮带托板2、无动力滚筒3和动力滚筒4之间，并由动力滚筒4传递动力而带动分拣皮带1在皮带托板2上沿两个方向往复运行以实施不同的分拣动作。
在侧板5的侧向，水平地固定安装折合板7、垂向地固定安装第一折弯连接板8、第二折弯连接板9。
所述的折合板7为一整体水平的板状部件，其外侧边缘具有多均段圆弧段103。
在折合板7上设置有多个折合板固定孔102，在侧板5的侧部安装带有固定板安装孔105的多组折合板固定板6；折合板固定孔102与固定板安装孔105对接，再通过沉头螺钉104将折合板7和折合板固定板6进行固定连接。
前后分拣小车相互串联时，其各自的折合板7的圆弧段103相互啮合且保留一定的间隙而可替代现有使用的风琴罩部件。
所述的折合板固定板6具有L型结构，其侧向通过螺栓与侧板5固定连接，其水平顶部通过螺栓分别贯穿折合板固定孔102、固定板安装孔105完成折合板7的水平固定。
在两侧的侧板5之间，横向地连接多组拉杆10，即从侧板5的外侧，通过螺栓将拉杆10的两端与侧板5进行固定连接。
第一折弯连接板8、第二折弯连接板9分别连接于一侧的侧板5。
所述的下部框架200，包括车架11和连接于车架11的小车结合板12、至少两组走行轮组件13和导向轮组件14、以及关节轴承组件15、次级板16、电气控制盒 安装件17。
其中，所述的车架11具有T型的整体式结构，包括横向部110和竖向部111；
机架11整体为铸造部件，在横向部110和竖向部111的两侧连接处设置有过渡部203，过渡部203通过冲压成型形成而与横向部110、竖向部111形成一体式结构。
沿机架11的竖向部111纵向开设有长腰槽204，在长腰槽204内外侧分别设置有多组内部螺纹孔205和外侧定位孔206，通过螺栓分别从外向内贯穿螺纹孔205和外侧定位孔206而将插入长腰槽204的次级板16进行锁紧固定。
具体地，先将次级板16插入长腰槽204中，然后将螺栓穿过外侧定位孔206，则螺栓前端顶入内部螺纹孔205中，则螺栓从外向内将次级板16的内侧面压向长腰槽204的侧壁，继续紧固螺栓最终将次级板16与长腰槽204的内侧面压紧，最终实现次级板16的安装与间隙调节操作。
两组走行轮组件13、导向轮组件14分别通过销轴设置于车架11的横向部110的两端，关节轴承组件15的两侧通过螺栓连接于横向部110的横向中心。
在机架11内侧、销轴上套设有第一垫块215和第一防松垫圈217、第二垫块216和第二防松垫圈218，并在销轴顶端加装第一螺母219、第二螺母220，以将两组垫块分别压紧于机架11内侧面上。
在机架11的竖向部111顶部安装电气控制盒安装件17；在电气控制盒安装件17上焊接多组带有螺纹孔的小圆板303，并在电气控制盒安装件17侧部开设侧面孔304，将电气控制盒安装到位；
