ST 180 Crawler Mounted Drilling Rig Operation Attentions
When the drill bit touches the hard soil layer and the drilling speed is slow, it can be pressurized with the pressure rod to speed up. If the drill pipe is skewed, it can be adjusted with the hook on the pressure rod. A mud pit with width of 2m, length of 3M and depth of 1m shall be excavated around 5m away from the drilling machine for slurry mixing when the drilling machine drills into the sand layer. As soon as the thread is disengaged, make it separate immediately. When withdrawing the rod, pay attention to avoid the swing of the mother rod to avoid thread damage. At the same time, the staff shall tighten the steel wire rope. It is used for flushing soil during drilling. Avoid relative movement between external thread and internal thread and wear the thread. After the work of the drilling rig is completed, the rod shall be retracted. When the rod is retracted, pull the lifting wrench to make the drum roll and drive the drill pipe to rise through friction. When the screw head of the mother rod is exposed. When docking the drill pipe, the throttle of the diesel engine shall be small, and the drill pipe shall not swing left and right as far as possible to avoid premature damage of the drill pipe thread. Close the valve under the rotary table and engage the reverse gear to retract the lever.
