随着地下矿山采矿工艺和规模的不断发展,电动铲运机已成为现代采矿工艺的主导设备,设计制造工艺和技术性能不断提高,其卷缆导向器在降低拖拽电缆故障率,提高电缆使用寿命方面有了显著的效果。笔者将介绍3种类型卷缆导向器的结构特点,分析不同结构卷缆导向器的优缺点及发展趋势。1结构特点及优缺点比较1.1“井”字形固定式卷缆导向器以EST-3.5电动铲运机为例,该设备是阿特拉斯·科普柯公司生产的较早用于在地下矿山的电动铲运机,它的卷缆导向器是一种“井”字形固定式
With the continuous development of underground mining technology and scale, electric scraper has become the leading equipment of modern mining technology, design and manufacturing technology and technical performance continues to improve, its cable guide in the drag cable to reduce the failure rate and improve cable use Life has a significant effect. The author will introduce the structural characteristics of the three types of cable guides and analyze the advantages and disadvantages of different types of cable guides and their development trends. 1 structural features and advantages and disadvantages of comparison 1.1 “well ” shaped fixed cable guide to EST-3.5 electric scraper, for example, the device is manufactured by Atlas Copco earlier used in underground Mine electric scraper, its cable guide is a “well ” shaped fixed
