摘要

根据冲击破碎机理和动力学分析,设计一种高效率的旋转式液气压混合冲击破碎机械,重点设计冲击钎杆及其安装机构、驱动钎杆旋转的液压马达机构、撞击钎杆的液气压混合活塞往复机构,以解决钎杆与马达旋转轴及活塞杆同轴定位问题;同时设计了简单高效的液气压缸一体化活塞往复撞击的机构;提出钎杆与马达输出轴同步旋转冲击系统的解决方案,以及液压活塞和气压活塞同步驱动撞击钎杆产生往复冲击运动的技术方法,并给出工作原理图和装配关系图。该机械创新实现了钎杆冲击时既产生轴向冲击力又产生径向离心力的合成冲击效果,破碎效率更高,效果更好。
        According to the impact crushing mechanism and dynamic analysis,a high-efficiency rotary hydraulic-pneumatic hybrid impact crushing machine was designed,which mainly included impact drill rod and its installation mechanism,hydraulic motor mechanism driving the rotation of the drill rod and reciprocating mechanism of hydraulic-pneumatic hybrid piston impacting the drill rod.It solved the problem of coaxial positioning of the drill rod and the motor rotating shaft and the piston rod.A simple and efficient mechanism for reciprocating impact of hydraulic and pneumatic cylinder integrated piston was designed.The solution of synchronous rotating impact system between drill rod and motor output shaft and the technical method of reciprocating impact motion produced by hydraulic piston and pneumatic piston driving impact drill rod synchronously were explained.And the working principle diagram and assembly relationship diagram were given.The mechanical innovation achieves the synthetic impact effect of both axial impact force and radial centrifugal force when the drill rod is impacted.The crushing efficiency is higher and the effect is better.
