ABSTRACT
Among the gas drainage drilling rigs, the entire hydraulic drill has some advantages :It is convenient for velocity modulation and its governor deflection is big; In the situation of the same power ,the hydraulic device has features like these:small size, light weight, compact structure ,stable transmission, quick response and so on. Multi-purpose hydraulic drill has important project value for gas drainage and the mine safety .
In the first ,this paper carried on analysis to the entire hydraulic rig''s operating mode . Basis on it,I have some improved designs to ZMY-150-rig’s hydraulic system. The improved designs mainly focus on the hydraulic pump stations, power head, gripping and framework: Put the control desk on the roof of the tank, the location of the valve operation is reasonable ,easy to operate; optimization is also used to minimize the volume of the transmission gear train of the driving head , which can reduce volume effectively.I have designed the compound clamp holder that is worked together by disc spring and hydraulic ram, the control valve of the holder is the three-valve 6; In the normal course of drilling,oil in the clamping circuit directly return to the oil tank which is energy saving , high efficiency and safety; I have also designed the machine rest base that the rack and the machine rest base can do relatively rotation , the design makes a drilling machine anchor to be possible to drill more holes,and it has reference value to some extent to the research of the high efficiency and entire hydraulic drilling rig . This hydraulic drilling rig is of the fission type that can be controled in a long distance , transpoted and installed conveniently ,suit for digging gas drainage hole underground.
Key words: hydraulic drill; gas drainage; design of driving head; optimal design
