Description

货叉装置 技术领域
本发明涉及一种智能货柜的货叉装置。
背景技术
目前在物流行业，通常使用带有货叉装置的小车等装置来移取货物，尤其是在货物面积较大时采用货叉装置可以方便的将所需移取的货物转移。由于智能货柜逐渐变得庞大、存放物品多样性，而且智能货柜的每行货柜间距有限，现有的货叉装置不能满足在较小的空间内完成较长空间的存取运动，而且现有的货叉装置在存取货盒时易出现卡死、倾斜等现象。因此上述的货叉均不能满足搬运较小货物时占用操作空间小，搬运效率高，节省时间的要求。
发明内容
本发明的目的就是为了克服上述现有技术存在的问题，提供一种货叉装置，其结构简单，使用与维修方便，传动效率高。
为实现上述目的，本发明的货叉装置提供以下技术方案，其包括：底座；设置在底座上的下齿条；设置在底座上的下导轨；支撑在下导轨上的传动装置；设置在传动装置上的上导轨；支撑在上导轨上的货叉本体；设置在货叉本体上的上齿条；其中，传动装置输出轴通过齿轮分别与下齿条、上齿条相啮合。
其中，传动装置包括：具有与下导轨相匹配的导轨槽的电机支架；固定在电机支架上的电机；其中电机的输出轴通过齿轮分别与下齿条、上齿条相啮合。
优选地，上导轨设置在电机支架的上部。
其中，货叉本体包括：支撑在上导轨上且相对于传动装置可移动的叉板；固定在上述叉板上的称重传感器；放置在称重传感器上的台面板；其中，上齿条设置在叉板上。
优选地，在台面板上设置有用于智能小车上的货叉装置存取物品货盒的定位的定位销。
优选地，齿轮为双向齿轮，下齿条、上齿条均为双齿条，实现消隙。
与现有技术相比，本发明的货叉装置的有益效果为：本发明的货叉装置在传动装置输出轴通过齿轮分别与上下齿条啮合，使得传动装置在下导轨上前后运动 的同时，货叉本体相对于传动装置也进行前后运动，因此可以实现双倍距离运动，而且具有本申请的货叉装置的智能小车在存取货盒时运动平稳，工作可靠。
附图说明
图1为本发明的货叉装置的三维示意图；
图2为图1所示的货叉装置的主视图；
图3为图2所示的货叉装置的右视图。
具体实施方式
智能货柜设置有多列货盒架，货盒架的货格内设置有用于存放货品的货盒，其中货叉装置安装在智能小车上，从而智能货柜的控制系统通过控制智能小车运动，从而按照指定的货盒进行存取。
如图1所示，本发明的货叉装置包括：底座1，该底座例如直接固定在智能小车上；设置在底座上的下齿条2；设置在底座上的下导轨3；支撑在下导轨上的传动装置；设置在传动装置上的上导轨6；支撑在上导轨上的货叉本体；设置在货叉本体上的上齿条8；其中，传动装置输出轴通过齿轮7分别与下齿条、上齿条相啮合。
本实施例传动装置优选采用电机传动装置，具体地，包括电机支架4、电机5、齿轮7。如图1所示，电机支架具有与下导轨3相匹配的导轨槽；电机固定在电机支架，电机的输出轴通过齿轮7分别与下齿条、上齿条相啮合。在电机支架上部设置与上导轨配合的导轨槽，当然也可以将上导轨6设置在电机支架的上部。优选地，齿轮7为双向齿轮，下齿条2、上齿条8也采用两条平行布置的齿条结构。为了实现消隙，齿轮7为双向齿轮，下齿条2、上齿条8均为双齿条。
具体地，当电机的输出轴旋转时，输出齿轮7也随之旋转，如图3所示，在齿轮7逆时针旋转时(如正转)，由于齿轮与下齿条的啮合作用，整个传动传动装置、货叉本体一起相对于底座向左(向前)运动，在齿轮与下齿条的作用的同时，齿轮与上齿条也相互啮合作用，于是货叉本体相对于电机支架向左(向前)运动，即传动装置在下导轨上向左(向前)移动一定行程时，货叉本体相对于底座向向左(向前)移动双倍的行程，从而提高了传动效率，节省了时间。电机8顺时针旋转时(如反转)时，实现货叉本体回退。
在本实施例中，货叉本体包括：支撑在上导轨上且相对于传动装置可移动的 叉板10；固定在上述叉板上的称重传感器9；放置在称重传感器上的台面板11；其中，上齿条设置在叉板上。其中为了平稳地支撑台面板，称重传感器优选地采用两个，且均匀地分布在叉板上。
为了在实际操作过程中能够使货盒在货叉存取运动中平稳，在台面板上设置有用于智能小车上的货叉装置存取物品货盒的定位的多个定位销12。
尽管上文对本发明作了详细说明，但本发明不限于此，本技术领域的技术人员可以根据本发明的原理进行修改，因此，凡按照本发明的原理进行的各种修改都应当理解为落入本发明的保护范围。
