FJD6·7型伞形钻架是山西省机械设计研究所和宣化风动机械厂联合设计的新一代六机伞形钻架(见图1)。简介如下: 该机针对国产FJD 6型六机伞钻存在的动臂刚性差,推进器马力小,机械化程度低,工作稳定性差等主要问题进行了完善化试验研究,设计了油缸-钢丝绳推进器型式,动臂设计了平动机构,同时液压系统设计了可靠的平动回路,整机高度低,收拢尺寸小,适用我国竖井掘进机械化配套要求. 一、主要技术参数适应井筒净直径(m)6～7 适应井筒净直径(m)7～8.2
FJD6 · 7-type umbrella-shaped drill rack is a new generation of six-machine umbrella-shaped drill frame (see Figure 1) jointly designed by Shanxi Machinery Design Institute and Xuanhua Pneumatic Machinery Factory. Brief introduction is as follows: The machine for the domestic FJD 6 type six machine umbrella drilling boom there is poor rigidity, low propulsion horsepower, low degree of mechanization and poor stability of the main issues such as the completion of the pilot test, designed the cylinder - wire rope thruster Type, boom designed translational mechanism, while the hydraulic system designed a reliable translation of the loop, the whole low height, Shoulong small size, applicable to China’s shaft excavation mechanization requirements. First, the main technical parameters to adapt to the net borehole diameter (m) 6 to 7 to adapt to the wellbore net diameter (m) 7 ~ 8.2
