1.桅杆支撑结构分类大型旋挖钻机的桅杆支撑结构主要有2种,一种是以宝峨为代表的大三角支撑结构,另一种是以土力为代表的平行四边形结构。采用大三角支撑结构的旋挖钻机数量较多,其在整机稳定性方面具有很大优势,尤其是在硬岩、深孔施工时表现尤为突出。大三角支撑结构的旋挖钻机拆装方便,设有支地液压缸,
1. Classification of mast support structure Large mast support structure of rotary drilling rig there are two kinds, one is represented by Po E triangle support structure, and the other is represented by the soil of parallelogram structure. The large number of rotary drilling rigs with the support structure of the big triangle has great advantages in machine stability, especially in hard rock and deep hole construction. Triangle support structure rotary drilling rig disassembly convenient, with branch hydraulic cylinder,
