穿梭车仓储是一种用于现代物流和存储行业的重要组成部分，当前的穿梭车式仓储一般包括货架、四向车、升降梯或者堆垛机，在存取货物时一般需要四向车将某层货架上的货物放置到指定位置，或通过升降梯或者堆垛机将货物运动至不同高度的货架中。
现有的穿梭车仓储大多是用于存储货物，大多只能通过叉车对货物进行转运，转运效率极低；此外，现有的部分穿梭车仓储内设置有四向车铺地轨道，以使四向车在铺地轨道上行驶以快速转运货物，提高转运效率，但是现有的铺设四向车铺地轨道的转角处，并不便于对地面进行完全找平且铺地轨道的转角处大多是通过水平铺地轨道交叉连接而成，从而铺地轨道的转角处会产生不水平，四向车行驶于铺地轨道的转角处易产生颠簸，继而会对四向车运输的精密仪器造成伤害；此外，在四向车系统宕机的情况下，工作人员驾驶叉车运输货物通过四向车轨道的转角处也易产生颠簸，这不可避免地会对叉车搬运的精密仪器造成伤害，严重者，会导致精密仪器发生损坏，因此，亟需一种可用于叉车平稳行驶的四向车铺地轨道转角调节结构。

本发明的一种可用于叉车平稳行驶的四向车铺地轨道转角调节结构，设置于仓库地面100开设的井字形的预留基坑110内，该四向车铺地轨道转角调节结构，如图1～3所示，包括找平 单元200、升降单元300、轨道单元400、安装单元500以及限位单元600。
找平单元200设置于仓库地面100开设的预留基坑110，预留基坑110的侧壁设置有支撑凸台111，找平单元200用于对预留基坑110进行找平，并在找平单元200的上端形成找平层，以使找平单元200上端安装的其他器件处于水平状态。
升降单元300转动设置于找平单元200的上端面；轨道单元400整体呈方形结构，且其侧边的纵截面呈C字形，轨道单元400的下端螺纹套设于升降单元300的上端，升降单元300用于驱动轨道单元400上升或下降，使轨道单元400的上端面与仓库地面100平齐或与其他非转角轨道的上端面平齐，轨道单元400用于使四向车在其上端面行驶。
可选地，轨道单元400的上端设置为方形以便于四向车行驶，轨道单元400的下端设置为圆环形，从而便于轨道单元400螺纹套设于升降单元300的上端。
其中，轨道单元400的下端设置有螺纹。
具体地，由于升降单元300与轨道单元400的下端螺纹连接，且升降单元300的位置固定且不能移动，所以在升降单元300转动的情况下，升降单元300能够带动轨道单元400上升或下降。
其中，在升降单元300转动带动轨道单元400向上移动的情况下，轨道单元400与仓库地面100平齐，以便于叉车平稳行驶；在升降单元300转动带动轨道单元400向下移动的情况下，轨道单元400与仓库地面100铺设的非转角铺地轨道平齐，从而四向车在从非转角铺地轨道切换到转角铺地轨道的情况下，四向车能够在轨道单元400进行平稳行驶，避免四向车发生颠簸。
其中，由于轨道单元400设置于升降单元300的上端，从而在找平单元200的上端面处于水平状态的情况下，升降单元300和轨道单元400也处于水平状态，从而便于四向车在轨道单元400的上端稳定行驶。
在其中的一些实施例中，升降单元300的下端连接有连接柱，连接柱的下端套设有连接轴承，连接轴承设置于找平单元200上端开设的槽孔的内部，从而升降单元300能够转动设置于找平单元200的上端。
安装单元500设置于轨道单元400的上端，其底部的若干安装腿510穿过轨道单元400与找平单元200固定连接，安装单元500的下端开设有安装槽520。
其中，安装单元500的上端面与仓库地面100平齐，以便于叉车平稳行驶。
其中，安装腿510可以设置于安装单元500的四边位置，也可以设置于安装单元500的四 角位置，安装腿510用于支撑安装单元500，使安装单元500能够水平布置。
在其中的一些实施例中，在转动升降单元300使轨道单元400向上移动的情况下，轨道单元400由于预留基坑110侧壁的限制，并不随升降单元300进行转动，从而轨道单元400能够沿安装腿510向上移动。
限位单元600设置于安装单元500底部，其输出端与轨道单元400侧壁开设的限位孔410相对应布置，限位单元600用于在轨道单元400与仓库地面100平齐的情况下，限位支撑轨道单元400，避免轨道单元400被叉车碾压而向下移动。
如图4～6所示，限位单元600包括传动大齿轮610、若干传动小齿轮620、若干齿条630、双输出轴电机640以及传动柱650。
传动大齿轮610转动设置于安装槽520内，传动大齿轮610能够在安装槽520内进行转动。
例如，安装槽520内设置有连接柱，连接柱的上端与安装槽520的槽底固定连接，连接柱的下端套设有转动轴承，转动轴承同轴设置于传动大齿轮610轴线开设的连接孔内，从而传动大齿轮610能够通过转动轴承在安装槽520内进行转动。
若干传动小齿轮620转动设置于安装槽520内，并分别与传动大齿轮610啮合连接，传动小齿轮620用于在传动大齿轮610转动的情况下，随传动大齿轮610一并转动。
其中，传动小齿轮620与安装槽520之间的转动连接方式与传动大齿轮610与安装槽520之间的转动连接方式相同。
其中，传动小齿轮620沿传动大齿轮610的周向设置于安装槽520内。优选地，传动小齿轮620为四个，且分别位于传动大齿轮610的前侧、后侧、左侧以及右侧。
齿条630的一端与对应的传动小齿轮620啮合连接，另一端活动穿过安装槽520侧壁开设的移动槽，与轨道单元400侧壁开设的限位孔410相对应布置，且齿条630的远离传动小齿轮620的一端设置为斜面，齿条630用于在对应的传动小齿轮620的带动下沿移动槽的开设方向进行移动，并进入到对应的限位孔410内，以对轨道单元400进行限位支撑，避免轨道单元400向下移动。
其中，由于齿条630远离传动小齿轮620的一端设置为斜面，从而齿条630的一端能够随轨道单元400的逐渐上升而逐渐进入到限位孔410。
在其中的一些实施例中，为了便于齿条630沿移动槽的开设方向进行移动，在齿条630的下端设置有若干滚轮。
双输出轴电机640固定设置于安装槽520内，双输出轴电机640的一输出端与传动大齿轮 610同轴连接，双输出轴电机640用于带动传动大齿轮610进行转动，进而使传动大齿轮610带动传动小齿轮620进行转动。
在其中的一些实施例中，双输出轴电机640可以通过若干L型安装柱固定于安装槽520内。
具体地，L型安装柱的一端与双输出轴电机640的外表壁固定连接，L型安装柱的另一端绕过传动大齿轮610与安装槽520的侧壁固定连接，从而双输出轴电机640能够带动传动大齿轮610转动，传动大齿轮610转动也不会触碰到L型安装柱。
传动柱650固定设置于双输出轴电机640的另一输出端，且传动柱650的下端偏心设置有内齿轮651，内齿轮651的一侧与升降单元300的驱动齿轮320啮合连接，传动柱650用于带动驱动齿轮320进行转动，继而驱动齿轮320带动升降单元300进行转动，以使升降单元300驱动轨道单元400上下移动。
具体地，在双输出轴电机640进行工作的情况下，双输出轴电机640带动传动大齿轮610进行转动，传动大齿轮610带动若干传动小齿轮620进行转动，继而传动小齿轮620带动齿条630向限位孔410内进行移动，以对轨道单元400进行限位；此外，双输出轴电机640带动传动柱650进行转动，传动柱650带动升降单元300进行转动，从而升降单元300能够驱动轨道单元400向上移动，以使轨道单元400与仓库地面100进行平齐。
其中，在轨道单元400逐渐上升的情况下，齿条630远离传动小齿轮620的一端逐渐进入到限位孔410内，从而在轨道单元400上升至与仓库地面100平齐的情况下，齿条630远离传动小齿轮620的一端完全进入到限位孔410内，以对轨道单元400进行支撑限位。
其中，工作人员可以通过调节内齿轮651的内径和内齿轮651内部螺牙的密度，控制驱动齿轮320的转速，以使轨道单元400上升至与仓库地面100平齐的情况下，齿条630远离传动小齿轮620的一端刚好完全进入到限位孔410内，以对轨道单元400进行支撑限位。
如图5～6所示，升降单元300包括升降螺纹筒310和驱动齿轮320。
升降螺纹筒310转动设置于找平单元200的上端，升降螺纹筒310的外侧壁沿周向设置有螺纹，从而升降螺纹筒310能够与轨道单元400的下端进行螺纹连接，继而在升降螺纹筒310转动的情况下，轨道单元400能够上下移动。
其中，升降螺纹筒310的下端与找平单元200的上端通过旋转柱和旋转轴承转动连接，从而升降螺纹筒310能够在找平单元200的上端面进行转动。
具体地，升降螺纹筒310的下端与旋转柱的上端固定连接，旋转柱的下端与旋转轴承的内 圈进行连接，旋转轴承的外圈与找平单元200的上端进行连接，从而升降螺纹筒310能够与找平单元200的上端进行转动连接。
驱动齿轮320同轴设置于升降螺纹筒310内，并与内齿轮651的一侧啮合连接，在驱动齿轮320转动的情况下，驱动齿轮320能够带动升降螺纹筒310进行转动。
其中，驱动齿轮320与传动大齿轮610同轴布置。
如图7～9所示，找平单元200包括支撑板210、若干第一找平块220、若干第二找平块230、若干轴承240以及找平板250。
支撑板210铺设于预留基坑110内，其中，支撑板210可以为金属板，也可以为非金属板，如砼板。
若干第一找平块220间隔设置于支撑板210的上端面，其上端开设有螺纹孔221；第二找平块230设置于对应的第一找平块220的上端，并与对应的螺纹孔221螺纹连接；轴承240套设于对应的找平块的上端；找平板250设置于支撑板210的上方，其下端开设有若干调节孔420，调节孔420套设于对应的轴承240上。
具体地，工作人员在对找平板250进行找平的情况下，工作人员转动第二找平块230，使第二找平块230与第一找平块220发生相对转动，从而使第二找平块230上升或下降，继而第二找平块230带动轴承240和找平板250上升或下降。
例如，在找平板250的一侧较高的情况下，此时工作人员转动找平板250一侧的第二找平块230，使第二找平块230进入螺纹孔221内，从而降低找平板250一侧的高度，以对找平板250进行找平。
进一步地，为了避免找平板250被长时间压迫导致第二找平块230转动进入到对应的螺纹孔221内，找平单元200还包括若干限位块260，限位块260设置于对应的第二找平块230上端开设的第一档位孔231和对应的螺纹孔221开设的第二档位孔222内，用于对第一找平块220和第二找平块230进行限位，避免第一找平块220与第二找平块230之间发生相对转动。
其中，每一第一档位孔231内均设置一限位块260，且第一档位孔231和对应的第二档位孔222上下对应布置。
在其中的一些实施例中，如图1～2所示，四向车铺地轨道转角调节结构还包括若干升降档轨单元800，若干升降档轨单元800对应设置于轨道单元400的上端的四边位置，升降档轨单元800用于避免四向车脱轨。
其中，在四向车在轨道单元400的上端行驶的情况下，升降档轨单元800向上延伸以对四 向车进行限位，避免四向车脱轨。
其中，在四向车系统宕机的情况下，升降档轨单元800向下收缩至于仓库地面100平齐，以避免影响叉车稳定行驶。
在其中的一些实施例中，如图10所示，升降档轨单元800包括若干升降元件810和若干档轨元件830。
若干升降元件810对应设置于轨道单元400开设的若干升降槽820内；档轨元件830设置于对应的升降槽820内，若干档轨元件830的下端分别与若干升降元件810的输出端固定连接。
其中，每一升降槽820内可以设置一升降元件810，也可以设置若干升降元件810。
其中，每一档轨元件830的下端可以与若干升降元件810的输出端固定连接，也可以与一升降元件810的输出端固定连接。
具体地，在档轨元件830需要上升的情况下，升降元件810的输出轴向上延伸以推动档轨元件830向上移动；在档轨元件830需要下降的情况下，若干升降元件810的输出轴同时向下收缩，以带动档轨元件830向下移动。
在其中的一些实施例中，升降元件810与控制单元700电性连接，从而控制单元700可以控制升降元件810的输出轴向上延伸或向下收缩。
进一步地，如图11～12所示，四向车铺地轨道转角调节结构还包括若干支撑单元900，支撑单元900设置于对应的限位孔410的侧壁开设的调节孔420内，支撑单元900的下端与支撑凸台111相对应布置，用于在限位单元600的带动下支撑轨道单元400。
进一步地，支撑单元900包括支撑块910和复位弹簧920。
支撑块910设置于调节孔420内，支撑块910的下端与支撑凸台111相对应布置，支撑块910用于支撑轨道单元400；支撑块910开设有驱动槽911，驱动槽911与齿条630对应布置，驱动槽911用于容纳齿条630，并在齿条630逐渐进入到驱动槽911的情况下，带动支撑块910向下移动；复位弹簧920设置于调节孔420内，复位弹簧920的第一端与调节孔420的侧壁固定连接，复位弹簧920的第二端与支撑块910的侧壁固定连接，复位弹簧920用于在齿条630离开驱动槽911的情况下，使支撑块910复位。
在限位单元600的齿条630远离传动小齿轮620的一端进入到限位孔410的情况下，齿条630朝远离传动小齿轮620的方向移动进入到驱动槽911内，继而在齿条630远离传动小齿轮620的一端完全进入到驱动槽911的情况下，支撑块910的下端与支撑凸台111相抵接，从而支撑块910支撑轨道单元400。
在其中的一些实施例中，如图13所示，四向车铺地轨道转角调节结构还包括控制单元700，控制单元700设置于安装槽520，并与双输出轴电机640电性连接，控制单元700用于控制双输出轴电机640的开启或关闭，
其中，控制单元700可以为可编程控制器。
控制单元700包括无线通信模组710，无线通信模组710设置于控制单元700内，并与控制单元700电性连接。
具体地，无线通信模组710与云平台进行连接，从而无线通信模组710可以通过云平台与工作人员进行数据传输。
具体地，在工作人员想要开启双输出轴电机640的情况下，工作人员将电机开启指令发送到云平台，云平台将电机开启指令发送到无线通信模组710，继而无线通信模组710将电机开启指令发送到控制单元700，控制单元700根据电机开启指令控制开启双输出轴电机640。
其中，无线通信模组710可以为2G模块、3G模块、4G模块以及5G模块。
本实用新型的四向车铺地轨道转角调节结构的工作原理为：在四向车系统未宕机的情况下，控制单元700可以控制升降元件810的输出轴向上延伸，继而带动档轨元件830向上移动以避免四向车脱轨；在四向车系统宕机的情况下，控制单元700控制双输出轴电机640进行工作，继而双输出轴电机640带动传动大齿轮610和传动柱650进行转动，传动柱650带动驱动齿轮320进行转动，驱动齿轮320带动升降螺纹筒310转动，继而使轨道单元400向上移动直至轨道单元400的上端面与仓库地面100平齐；同时传动大齿轮610带动若干传动小齿轮620进行转动，传动小齿轮620带动对应的齿条630进行转动，齿条630进入到对应的限位孔410内部以对轨道单元400进行限位支撑。
以上实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
