一种便于攀爬树枝的脚扣研制 赵红伟 （云南省送变电工程公司云南省昆明市 650216） 摘要：本新型工具主要用于速生树木的修枝断尖，由于扣钩的前后端都有防滑钉，稳固牢靠， 提高了安全性，有效避免了打滑脱落导致高空坠落事故的发生，使人身安全得到了保障。提 高了舒适性，使用方便快捷，可以更长时间作业，大大提高了清理树障隐患的工作效率和降 低了作业人员的体力消耗。由于修枝断尖不需要办理砍伐证，也不受限砍政策的限制，处理 树障隐患非常方便，机动性较大，可有效避免树障隐患导致的线路跳闸，更好保证线路的安 全运行。桉树修枝断尖一般只需要 10 元/棵，比整棵砍伐 50 元/棵节省 40 元，具有非常好 的经济效益。修枝断尖与整棵砍伐相比，还具有林木保护和水土保持的作用。 关键词：攀爬树枝；脚扣；研制 A Study of the Development of Grapplers Suitable for Tree Climbing ZHAO Hongwei （Yunnan Power Transmission and Transformation Engineering Corporation Kunming, Yunnan 650216） Abstract: This new tool is mainly used for fixing broken branches of fast-growing trees. The grapplers have spikes attached on both ends, which provide enhanced stability and security and effectively avoid falling caused by slipping. It safeguards personal security, improves comfort and convenience, allows more time for the operation and substantially increases the work efficiency in clearing potential dangers caused by tree barriers. Since fixing broken branches doesn’t require cutting permits, free from restrictions of cutting policies, it is easy and flexible to operate, which can effectively avoid line tripping caused by tree barriers and maintain safety. The cost of fixing broken branches of eucalyptus is normally 10 yuan/plant, which is 40 yuan cheaper than cutting the whole tree (50 yuan/plant). Therefore fixing broken branches is comparatively of greater economic benefits with additional ecological values in forest protection and water and soil conservation.
