When the project drill rig after slipping phenomenon, after the second drill, you can see the display above the data to determine the thickness of sediment fall, after geological hardness also depends fall, if fall much soil words, and soil and relatively hard, then XY-4 type drilling rig pictures can be taken for a pile of smaller diameter drill bucket to solve under slipping phenomenon, due to the small diameter drill a larger gap between XY betta hole wall -4 type drilling rig where to sell, XY-4 type of soil under the fall in the weight of the drill pipe drilling bucket drilling rig and processing the effects of stress manufacturer, with clearance holes through the drill bucket is squeezed to the side wall of the XY-4 type engineering drill, small diameter drilling bucket compacted soils will be able to come into contact with normal drilling, When the small drill are promoted, they are squeezed into virtual earth next to fall into the small-diameter hole, did not fall into the hole muck It is the second large-diameter drill after drill bucket squeeze into the hole, so the large-diameter drilling bucket directly normal drilling. Rig periodic inspection of item 1, the main structure of the drilling rig status, structural connector bolts connecting pin structure, each structure welds, Barrel and check the condition of safety, especially before entering use, should a qualified units for their safety testing, qualified before use; 2, a variety of regular power head, operating cylinder, check the condition of the drill bit; 3, regular drum winch rope fall prevention device and two side edge height, roll wall situation, the rope trailing in the number of weeks to check on the roll. 4. Check the electrical system, the main test items as: Dedicated electrical box set and short-circuit protection and leakage protection devices, emergency off switch, electrical boxes damping device, fixed, lighting circuits, on the ground working device cable is prohibited as a carrier Flow zero lines; Yongfu County XY-4 type drilling rig _XY-4 type drilling rig equipment _ Prius Prius provided by Luoyang Drilling Equipment Co., Ltd.
