| Abstract: | To meet the requirement of small diameter and shallow hole drilling for gas drainage in coal tunnel,the ZDY1200L track-mounted hydraulic tunnel drilling rig has been developed.The track-mounted mechanism is used for high mobility,the load sensing technique is used in the open cycle double-pump hydraulic system to decrease the power wastage.The direction of drilling can be adjusted quickly and simply by the rotating table.The operation and maintenance are convenient with the electromagnetic starter and lamps.The field experiment shows that the rig has high operability,mobility,reliability and drilling efficiency,as well as the locating drilling direction and fixing the rig are very convenient. |
