The invention discloses an ultralow pore continuous automatic rod assembling and disassembling hydraulic
coal drill and a rod assembling and disassembling method thereof. The
drill comprises two rod storing and disassembling boxes, a middle clamp, a front clamp, hydraulic telescopic support stand columns, a
manipulator hydraulic support, hollow rotating platforms, manipulators, a working table, anoblique axis variable-displacement motor, a speed
reducer, a rack base and a rubber sleeve hydraulic chuck. The
oblique axis variable-displacement motor, the speed
reducer, the rubber sleeve hydraulic chuck, the rod storing and disassembling boxes and the clamps are installed on the lower portion of the working table, the
manipulator hydraulic support is installed on the upper portion of the working table, and a working method that the two rod storing and disassembling boxes act together, and the manipulators conduct rod assembling and disassembling from the bottom of the
drill is adopted. The drill has the obvious advantages that structural arrangement is ingenious, the drill height is greatly lowered, operation is convenient, the continuous automatic rod assembling and disassembling functions are achieved, the work efficiency is improved, the security work is safe and stable, and the manufacturing cost is lowered; the problem that an existing drill cannot drill an ultralow pore, andcontinuous rod assembling and disassembling cannot be conducted is solved.
