煤矿悬臂式掘进机伸缩结构的设计

Design of Telescopic Structure of Cantilever Roadheader in Coal Mines

总结分析了现有悬臂伸缩结构形式在用于大功率重型岩巷掘进机时存在的问题及缺陷,并设计了一种新型伸缩结构,在改善伸缩结构强度、刚度的基础上,通过特殊的设计解决了方箱式结构加工工艺性差的问题。通过设计分析,确保该结构的可靠性、稳定性,以期为解决岩巷纵轴掘进机长期以来无法实现悬臂伸缩功能的问题提供新的思路。

This paper summarizes and analyzes the existing problems and defects of cantilever telescopic structure used in high-power heavy-duty rock roadway roadheader, and designs a new telescopic structure. Through the design analysis, the reliability and stability of the structure are ensured, which provides a new idea to solve the problem that the longitudinal shaft roadheader of rock roadway can not realize the cantilever expansion function for a long time.
