The pillars are sturdy according to the needs of the holes. The upper and lower ends of the pillars should be covered with wooden boards. The horizontal shaft and the snap ring are mounted on the pillars according to a certain height and direction. The machine is lifted by a hand winch, fixed on the pillars according to the required viewpoint, and then the hole of the drill is adjusted. . When the DTH Drilling Rig is up to the hole, it is used in parallel with the two horizontal axes. When drilling the horizontal and the hole, usually only one horizontal axis is used. When drilling other holes, the best use of three horizontal axes will help the two horizontal axes. The shafts are connected, one end is fixed on the carriage, and the other end is attached to the pillar, and the carriage is sturdy together with the main horizontal axis. Tighten the horizontal shaft and the snap ring bolts after the machine orientation is fixed.

When starting the operation, you should carefully check whether the gas-water pipeline is firmly connected and there is no appearance of air leakage and leakage. Check whether the oil filler is filled with oil. Check that the screws, nuts, and joints of each part are now tightened, and the column is indeed very strong.

In the operation, we must know all kinds of detailed operation methods and procedures, pay attention to check the gas waterway, the joints of various parts of the screws and joints, and the solid state of the column and the horizontal axis. When drilling, give more water to reduce dust and drill. When the chiseling does not allow the rotation, it is not normal to pay attention to the magma discharge during the construction operation of the drilling and drilling rig. When drilling the lower hole, the magma is not easy to be discharged. It is necessary to spray the gas and water mixture frequently to blow out the magma accumulated in the bottom of the hole. If necessary, it is necessary to drill and punch. It should be noted that the sound of the impactor and the working condition of the rig are normal.

Finding an abnormal appearance should be immediately viewed by parking. When drilling the hole, the hole should be drilled into the drill pipe with a large diameter drill head, and the drill pipe should be exposed to the ground 100-200 mm long to prevent the mud from falling into the hole. When the drilling machine stops the operation in a short time, it should be given A small amount of air pressure to avoid the intrusion of sand into the interior of the impactor, if it is suspended during a longer period of time.

When the drilling operation program and the mast are opened, the motor is first started, and the handle of the manipulator is pulled after the normal transfer is performed. Make it the right driving force, and then pull the handle that handles the impactor to the working position. After rock drilling, the water valve can be opened to maintain the proper share of the gas-water mixture. A drill pipe is drilled when the pusher moves the mast to the collet. To stop the motor operation and stop the air supply to the impactor, send water, insert the fork into the drill rod groove of the holder, retract the motor rotary slide, disengage the joint from the drill rod, and then connect the second drill rod, press this Cycle through the work.
