Abstract: A kind of shallow hole water exploration and drainage drilling rig ZDY1300L is developed, the drilling rig can satisfy the requirement of water exploration and drainage drilling construction, and it is light, strong and efficient. Meanwhile, it has many advantages, such as high efficiency of shift and drilling, short aided time, small workload, the construction ability of large angle and multiple holes. According to the special conditions of water exploration and drainage process construction, the supporting devices and the hydraulic system are developed, including the long stroke feeding device, the manual holder, the adjustment device of large dip angle and azimuth angle, waterproof and water transmitting device, the new drag board and power head slide protection in the hydraulic control system, the operating console away from orifice.
