摘要
设计了一种用于迈步式扩孔刀头的多缸迈步推进和机械锁紧机构,介绍了其结构与工作原理。该机构具有迈步推进力小、结构紧凑及锁紧可靠等优点,能在井下破岩工作面恶劣工况下,顺利实现迈步与锁紧的程序动作。
A kind of multi-cylinder stepping and mechanical locking mechanism for the sequential reaming cutter was designed, and its structure and working principle were introduced. The mechanism was characterized by low stepping propulsion, compact structure and reliable locking etc. In severe underground rock-breaking working face, it accomplished smooth stepping and locking.
