摘要
YZ - 4 0 0型多功能液压钻机是以 2 0 0～ 5 0 0mm大口径薄壁金刚石钻头钻取钢筋混凝土为主的液压动力头钻机 ,同时兼顾 91和 110mm金刚石岩心钻进。介绍了该机的技术参数、设计原则和结构特点。
The article introduces the main technical parameters, design principles, structure and characteristics of YZ-400 multipurpose hydraulic drill. This hydraulic top driven drill was designed mainly for 200～500 mm diameter borehole drilling through reinforced concrete using thin wall diamond bits. Meanwhile 91 & 110 mm diameter diamond coring was taken into account.
