摘　　要：针对液压锚杆钻机的旋转供水机构在使用过程中漏水和使用寿命短的问题,分析了供水机构的失效原因,设计了一种以格莱圈密封为主和多种密封形式为辅的组合密封结构,并设计了具有泄水结构的防水套。新型旋转供水机构大大增强了密封效果,提高了锚杆钻机的可靠性和使用寿命。In view of the leakage and short-life of the existing rotational water supply structure of hydraulic roof boher, analyzes the causes of fault, and designs a combination sealing structure based on the GELAI Ring and various complementary sealing type, as well as the water-proof sleeve with drainage way. The new structure greatly enhances the sealing effect and improves the reliability and service life of the roof boher.
