On the drilling rig drilling rig structure and working principle is also part of a drilling rig, rig blast Which is good, is a classification and extension drilling rig, engineering drilling rig is mainly used for high-rise buildings, ports, docks, electricity, bridges and other projects large diameter pile construction rig. We work together to understand the structure and working principle of drilling rig. Engineering Drill column is foldable, uses a box-form cross-sectional structure, both sides of the column with a circular or square circular slide as the power head, drill up and down movement of the guide and torsion. The rig is equipped with box-folding columns use the hydraulic cylinders landing, operate convenient transportation do not disassemble. Column rig substructure and the plate is hinged in the rear with the diagonal brace hinge, blasting rig manufacturers, used to complete the power head, steel cage and grouting conduit landing, power head can move up and down along the guide rails. Inspection hole drill hole drill work before as a large ore excavation machinery, blasting rigs, the former general usual work must start trouble of checking maintenance of machinery and equipment, accident prevention failure. During normal use, the work before the job is how to prepare it? The first point is the maintenance personnel must carefully check whether gas water pipe connections are secure, there is no leak leaking phenomenon, prevent entry of air drills phenomenon lies in the drilling process, the blasting rigs offer, to avoid damage to the drill bit. It has filled the second point is to check the oiler oil, which is the basic common sense to check power system must be checked. The third point is to check the various parts of screws, nuts, joints, etc. is already tightened the top of the column is indeed very strong. Do the work of three of the above checks, to start submersible drilling rig began operations. Taian blasting rig _ Long industry machinery (certified) _ blasting rig by Dragon Machinery Co., Ltd.
