为简化结构和改善操作条件,一般凿岩钻车操作工作台都直接安装在底盘架上。为减轻机械振动对操作人员的有害影响,在工作台和底盘之间设置减振器,可降低振动级6～10分贝。但并非总能保证操作工作台在允许振动级。对凿岩钻车所进行的动力学试验研究和分析研究表明,依靠改变钻臂提升液压缸和推进机构的弹性缓冲参数,可大收效益。而最应注意的是后者,因为推进机构参数的正确选择,可减少推进器上的负荷以及
To simplify the structure and improve the operating conditions, the general drilling rig operating table are mounted directly on the chassis frame. To reduce the harmful effects of mechanical vibration on the operator, a shock absorber can be set between the workbench and the chassis to reduce the vibration level by 6 to 10 dB. However, it is not always possible to ensure that the operating table is allowing vibration levels. The dynamic experimental research and analysis on rock drilling rigs show that it can greatly benefit by changing the elastic cushioning parameters of the boom to raise the hydraulic cylinder and the propulsion mechanism. Most notably, the latter, because the correct choice of propulsion machinery parameters, can reduce the load on the thrusters and
