Abstract
Provided is a double-drill drilling-type coal mining machine drill stem bearing stabilizer. The double-drill drilling-type coal mining machine drill stem bearing stabilizer comprises a bearing transmission assembly, a coal pillar supporting assembly and drill stems. High profiled shifted gear shafts and bearing sets are arranged inside a bearing transmission device. The input end and the output end of the bearing transmission assembly at the two ends of a bearing transmission box body are engaged with the high profiled shifted gear shafts through inner splines. The torque transmission is achieved through the output ends of the drill stems and the input end of the bearing transmission assembly. The two drill stems are bonded together by the bearing transmission box body, and two drilling tools are prevented from deviating during drilling working. The coal pillar supporting assembly on the six free faces of the bearing transmission box body provides supporting for the drilling tools. The self-impulsion of a supporting spring inside the coal pillar supporting assembly can buffer the pressure of the drill hole collapse. A circular hole formed by a middle connecting part and a cover plate on the bearing transmission box body is used for fixing a ventilating pipe and a water pipe. By matching the double-drill drilling-type coal mining machine drill stem bearing stabilizer with an ordinary drill stem, the problem of drilling tool deviation can be effectively solved, the drill hole collapse is prevented, the drilling tools are prevented from being buried, and the working efficiency of a double-drill drilling-type coal mining machine is improved.
