摘要
介绍了5 000m及5 000m以上新型自行走钻机大模块快速搬家的新理念和新设备,分析了ZJ50/3150DB型自行式钻机运输单元划分、液压缸起升底座和新型单轴绞车的结构特点和控制性能。该钻机可实现大吨位、高重心钻机部件安全方便地运输和安装。
A new concept and new devices of self-walking drill rig with drilling depth of 5000m and above,which can be fast moved and installed in large modules,is introduced.Also an analysis is made for the structural division,hydraulic lifting substructure and one single shaft drawworks.The heavy load self-walking rig with all facilities on it on high gravity is realized.
