摘要
智能化的轨道物流传输系统正逐渐被应用于现代化的综合性医院中,现有的轨道物流小车行驶速度低、载重量不足。为了应对日益增长的物流压力,设计了一种高速重载双驱型轨道物流小车。该小车改变了原有的物流小车单电动机驱动模式,采用两台无刷直流电动机并行驱动,并通过特别设计的隐形摩擦驱动机构进一步提升了爬坡能力。针对并行双驱结构、隐形摩擦驱动结构、类剪刀式前后车架支撑结构以及周向定位装置等主要车体结构进行了详细的介绍。试验表明,该小车最大载重量达40kg;在载重20kg的情况下,平直路段最大运行速度达到1.5m/s,60°斜坡最大爬升速度为0.8m/s,车辆自重系数小且运行平稳可靠。
Intelligent rail logistics transmission system is gradually applied to modern general hospital. Low driving speed and insufficient load exist in the current rail logistics vehicles. To meet the needs of the growing logistics, a high speed heavy load dual-drive rail logistics vehicle is designed. This vehicle is equipped with two brushless DC motors. In addition, its climbing ability is enhanced by the specially designed hidden friction drive mechanism. The structure design of the main body, including dual-drive, hidden friction drive, scissor-like front and rear support framework and peripheral positioning device, is introduced in detail. The results of the tests show that maximum load of the designed vehicle is 40 kilograms, its maximum straight forward running speed is 1.5 m/s and the maximum climbing speed at 60-degree slope angles is 0.8 m/s when it is loaded with 20 kilograms goods. The designed vehicle is characteristic of light dead-weight and smooth and reliable running.
