新型锚杆机结构设计

Structural Design of New Bolter

阐述了一种新型结构锚杆机,该锚杆机与以往的锚杆机主要区别有动力头推进油缸和支架推进油缸改用双伸缩油缸;顶板增加了夹持油缸,提高了钻孔时钻头的稳定性;顶板支撑油缸集成于框架体内,缩小体积,方便维护。动力头采用变量双速马达,可提高钻孔效率。

Described a new type structural bolter. The main difference between the bolter and the previous bolter is that the power head propulsion oil cylinder and the support propulsion oil cylinder were replaced by the double expansion oil cylinder;the top plate increased the clamping oil cylinder to improve the stability of the drill bit during drilling;the top plate support oil cylinder was integrated with the frame body to reduce the volume and facilitate maintenance. Variable two speed hydraulic motor was used in power head to improve drilling efficiency.
