设计了一种分负载格构式煤层气车载钻机的钻塔,并采用数值模拟的方法进行了强度校核,优化了钻塔斜支撑结构,使钻塔上部的变形量降低30%,最大等效应力降低40%;改进了钻塔腹杆结构,使钻塔上部的变形量降低14%。 A drilling tower with sub-gridded lattice CBM vehicle rig was designed and its strength was checked by numerical simulation. The inclined support structure of the tower was optimized to reduce the deformation of the upper part of the drill tower by 30% and the maximum The effective stress is reduced by 40%; the web structure of the derrick is improved so that the deformation of the upper part of the derrick is reduced by 14%.
