针对目前生产企业安全运输大型零部件和大型重物的需要,设计开发了一种通过手控按钮盒操纵控制的重载电动运输台车。介绍了电动运输台车各部分的组成、结构以及工作原理,论述了传动系统、转向系统和制动系统的设计。通过对电动运输台车样车的性能测试,证明该电动台车的各项性能指标符合设计要求,具有行驶安全性能好、结构紧凑、承载力大、操作简便灵活、能耗低、无污染、低噪声、高机动性等优点,特别适用于工厂厂区、大型仓库、生产车间内大型、异型重物的安全运输,是一种具有广阔应用前景的新型物流运输车辆。 In response to the current needs of manufacturers to safely transport large parts and heavy loads, a heavy-duty electric transport trolley controlled by a manual button box is designed and developed. The composition, structure and working principle of each part of the electric transport trolley are introduced. The design of the transmission system, the steering system and the braking system is discussed. Through the performance test of electric trolley-like vehicles, it proves that the performance indexes of the electric trolley meet the design requirements, and has the advantages of good driving safety, compact structure, large carrying capacity, simple and flexible operation, low energy consumption, Low noise and high maneuverability. It is especially suitable for the safe transportation of large-sized and shaped heavy objects in factories, large warehouses and production workshops. It is a new type of logistics transport vehicle with broad application prospects.
