Description

仓储运输电动车 技术领域
本发明涉及一种货运装置，特别涉及一种在仓库、商场、码头等场所使用的货运装置。
背景技术
现有技术中，有一种三轮仓储运输电动车，包括底座，底座上表面设有一个承载板，底座下侧设有三个或四个滚轮，其中至少前部的滚轮为万向轮，底座上向上伸出一拉臂，货物放置在承载板上，拉动拉臂可将仓储运输电动车拉走，达到移动运输货物的目的。其不足之处在于：这种货运车需要采用人力进行运输，费时、费力。现有仓储运输的技术中，也有采用铲车进行货物搬运的，铲车需要安装内燃机，在空间狭小的场所，其排出大量废气，会污染环境，同时，也会影响货物的安全和品质。
发明内容
本发明的目的是提供一种仓储运输电动车，使其具有安全、环保、高效运输货物的能力，同时，可节省人力。
本发明的目的是这样实现的：仓储运输电动车，包括底座，底座上表面设有一个承载板，所述底座前部中心下方设有一个转向驱动轮，底座后部两侧下方分别设有一个随动轮，转向驱动轮设置在转向杆下端，转向驱动轮与直驱电机传动连接，转向杆穿过底座向上伸出，转向杆上端设有转向及加速控制器，用于控制直驱电机的电池、电机驱动器，以及给电池充电的充电器安装在底座内。
本发明工作时，将货物放置在承载板上，货运人员站立在转向杆后侧，通过操纵转向及加速控制器，将货物运输到适当地点，再进行卸货。电池的电消耗后，可充电补充；该装置在工作场所没有污染物排放，具有环保、安全、高效的优点，可以节省人力，该装置可用于仓库、码头、机场、超市等场所的短距离货运，尤其适用于室内环境的货物运输。
为进一步方便货运，所述底座前端设有前踏板，前踏板经铰链连接在底座前端。运输货物时，操作人员不仅可站在承载板上进行操纵，也可以站在前踏板上进行操纵。
为方便制动，所述底座上位于转向杆一侧设有主刹车踏板，所述主刹车踏板经刹车装置与任一随动轮相连。相应地，底座前端与前踏板位置对应设有辅助刹车踏板，所述辅助刹车踏板经刹车装置与任一随动轮相连。两踏板可共用一套刹车装置。
为避免可能造成的翻车，所述底座上位于转向驱动轮两侧设有脱离地面的辅助支撑 轮。在正常运输时辅助支撑轮脱离地面，当货物偏载，出现问题时，辅助支撑轮着地，避免了翻车、倾倒和货物移位。
作为本发明的进一步改进，在承载板上下侧设有升降机构，所述升降机构包括相互交叉铰接的两组支撑杆，其中一组支撑杆的一端与底座相铰接，其另一端设有滚轮支承在承载板下侧；另一组支撑杆的一端与承载板相铰接，其另一端设有滚轮支承在底座上，底座上还设有一可摆动的螺杆，螺杆与一举升电机传动连接，螺杆上啮合有螺母，所述螺母与其中一组支撑杆相铰接。工作时，将货物放置在承载板上，可方便将货物举升抬起，以便于装卸，具有环保、安全、高效的优点，可以节省人力。
为方便包装运输，所述转向杆为折叠式结构。在包装运输时，将转向杆折叠，可减小包装尺寸。
附图说明
图1为本发明结构示意图。
图2为本发明又一结构示意图。
其中，1 转向及加速控制器，2 转向杆，3 连接销，4 底座，5 前踏板，6 主刹车踏板，7 转向驱动轮，8 辅助支撑轮，9 随动轮，10 承载板，11 举升电机，12 螺杆，13 螺母，14、15 支撑杆，16、17 滚轮，18 直驱电机，19 辅助刹车踏板。
具体实施方式
实施例1
