钻臂是凿岩台车钻孔定位及钻机的支撑机构,其工作性能好坏直接影响钻孔效率及钻孔质量。一旦钻臂出现故障,整个钻孔作业将无法顺利完成。本文对钻臂故障进行分析并介绍排除方法。1.钻臂移动不稳钻臂的各种动作都是由液压缸控制的。钻臂移动不稳,说明液压缸的动作不稳,而液压缸动作不
Drilling arm is a drill rig positioning and drilling rig support mechanism, the performance of its work directly affect the drilling efficiency and the quality of drilling. Once the drill arm fails, the entire drilling operation will not be completed successfully. This article analyzes the boom failure and introduces the elimination method. 1. Drill boom unstable movements of the arm movements are controlled by the hydraulic cylinder. Drum unstable movement, indicating the instability of the hydraulic cylinder, hydraulic cylinder action is not
