摘　　要：为提高椰子采摘工作的作业效率和安全性,设计出一款简易椰树攀爬装置,并运用超景深显微技术对装置的安全性能进行磨损特性分析。模仿人类爬树动作,确定了攀爬装置的运动方式,完成对样机的设计;设计0-1 000 N的循环载荷攀爬试验,运用超景深显微镜的变焦镜头VH-200R瞬时拍摄了不同阶段的关键部件(支撑架、支撑杆以及钢丝绳)磨损状态。结果表明:攀爬装置在反复工作过程中,3个关键部件均因受到较大应力并发生变形,随着承重载荷的增加,变形程度逐渐加剧,磨损程度越来越大。To improve work efficiency and safety of coconut picking, a simple coconut tree climbing device is designed, and then the super depth microscopy approach is used to analyze the safety performance and the wear characters of this device. For starters, by simulating the action of human climbing, we determine the motion scheme of this device and complete the design; then a load climbing test is proposed to observe the three key components, including a supporting frame, a supporting rod and a wire rope. The infrared thermal imaging and acoustic emission detections are recorded by microscope lens VH-200 under the cycling load from 0 N to 1000 N. The results show that during the repeated operation of the climbing device, the three key components are all subjected to large stress and deformation. With the increase of bearing load, the deformation degree is gradually intensified, and the wear degree shows an increasing trend.
