II. Main features
1. It adopts full hydraulic rotary head transmission, stepless speed change, high drilling efficiency and low labor intensity.
2. The hydraulic system of the drilling rig is stable, reliable and has a long service life.
3. The rotary head adopts hydraulic speed change mode and is equipped with high and low gears to meet the requirements of various formations and different drilling processes.
4. The drilling rig has the function of crawler self-moving, and the equipment is easy and fast to move.
5. The frame rotation adopts a large-diameter slewing bearing. When necessary, the hole position can be easily turned to the side of the crawler for manual work.
6.The structure is compact, centralized operation, convenient and safe.
7.The column can be telescopic forward and backward to meet the needs of anchor construction.
8. The standard configuration adopts a single clamp at the hole mouth and is equipped with a special shackle tool. It is more convenient to disassemble the drill rod. A double clamp can also be selected to reduce the labor intensity and operation time of loading and unloading the drill rod.
III. Construction scope of the drilling rig:
1. It is suitable for high-speed drilling and mud slag removal in soil, sand and other formations; three-wing drill bits and one-shaped drill bits for drilling.
2. It is suitable for air down-the-hole hammer drilling and air slag removal in rock and broken layers.
3. Suitable for bottom hole hydraulic hammer drilling and mud slag removal in broken layers, sand and gravel layers and other strata with high water content.
4. Drill rod drilling and casing composite drilling.
5. Single-tube, double-tube, three-tube rotary spraying, swing spraying, fixed spraying and other rotary spraying processes can be realized (customer optional).
6. It can be used as a complete set of equipment with Xitan Equipment Company’s high-pressure grouting pump, mud mixer, rotary spraying, swing spraying drilling tools, guide, nozzle, three-wing drill bit, straight drill bit, composite drill bit.
7. It can be seamlessly connected with domestic and foreign drilling tools through reducers.
