摘要
ZDY4000LD定向钻机和配套随钻测量系统(MWD)适用于煤层定向长钻孔瓦斯抽采作业。介绍了钻机研制过程中针对稳固系统、主轴制动装置进行的仿真分析;阐述了定向钻机液压系统、主轴及夹持系统等关键技术。该型号定向钻机已为煤矿用户所接受,具有很大的技术发展空间。
It is an effective means to drill directional long boreholes in coal seam for gas drainage.ZDY4000LD directional drilling rig can m eet the demand of two ki nds of drilling methods,i.e.,down-hole motor drilling and rotary drilling.It is equipped with measurement while drilling system（MWD）.It serves well as directional drilling equipment for most of coal mines in China.In this paper,simulations of chassis support system and main shaft braking system were introduced,some key technologies of hydraulic system,main shaft braking and gripper system were also represented.Author analyzed and concluded that directional drilling and MWD technology have been adopted by coal mine users,it has bright future in technology development,it is also important for gas drainage and deep coal mining.
