The invention provides an unmanned tray truck. The unmanned tray truck comprises a tray truck frame, the frame is provided with two fork legs for lifting, and the unmanned tray truck is characterizedin that scissor fork lifting systems are arranged in the fork legs, and the scissor fork lifting systems are connected with a hydraulic power system; steering wheels used for travelling are arranged at the bottom of the frame, and a navigator is arranged at the top of the frame; and a laser barrier sensor is arranged on the outer side of the frame, an industrial personal computer and a battery system are further arranged on the frame, and the industrial personal computer is connected with the hydraulic power system, the navigator, the laser barrier sensor and the battery system through a control circuit. A double scissor fork structure is adopted for lifting, two lifting oil cylinders are rigidly connected with scissor forks through shafts and couplings, thus the lifting of the whole lifting structure is stable, and the whole lifting structure is more suitable for stacking and carrying of multiple trays. After special design, the scissor forks are hinged with a dry-type lining, the wear resistance and assembly accuracy are improved, meanwhile the maintenance and replacement are convenient, and thus the service life of the whole lifting structure is prolonged.
本发明提供一种无人托盘搬运车,包括托盘车车架,车架上带有用于举升的二个叉腿,其特征是,所述叉腿内设置剪刀叉举升系统,剪刀叉举升系统连接一液压动力系统;车架底部设置用于行走的舵轮,车架顶部设置导航仪;车架外侧设置激光壁障传感器,车架上还设置工控机和电池系统,工控机与液压动力系统、舵轮、导航仪、激光壁障传感器、电池系统通过控制电路连接。采用双剪刀叉结构进行举升,两个举升油缸通过轴与联轴器与剪刀叉实现刚性连接,使整个举升结构举升平稳,更适合多个托盘堆叠起来搬运。剪刀叉经过特定设计,铰接出采用干式衬套,耐磨性与装配精度提高,同时维修更替方便,使整个举升结构寿命增加。
