First analysis of drill is influenced by various factors in the practical work, analysis of working condition requirements, design a suitable tank circuit, support cylinder loop, boost cylinder loop, gripper hydraulic circuit and hydraulic motor hydraulic circuits, analysis in this paper, the working condition of various kinds of hydraulic circuits. Choose the reasonable hydraulic components, a complete assembly of the hydraulic circuit. Moreover, the design of the gripper types for holder normally closed type, the structure distribution evenly, relying on the disc spring and a cylinder clamping force, with hydraulic loosening, can clamping drill pipe is 73 mm and 63 mm. Mainly used for coal engineering hydraulic power head drill loading and unloading drill rod, its simple structure, convenient operation, good marketing benefit. This design request to design the reasonable structure of gripper, try to make the holder of small volume, good computing saucer reed and the clamping force of gripper hydraulic cylinder can provide, calculate the size of parts of gripper, the structure of the holder in finite element stress analysis, find out the unreasonable structure parts and improved.
