Auger drill pipe unlocking considerations
1 Resistance: It is very important to unlock when there is resistance in the spiral drill pipe drilling, because the drill bucket needs to provide resistance to unlock. 2 lifting power head: the function of lifting screw drill pipe power head is to eliminate the gap between the locking section of each drill pipe machine and prevent the drill pipe from being smashed. Another function is to reduce the friction resistance of the lock point of the machine and prepare for unlocking. 3 vibration. Sound: If you carefully identify, you can feel that when you unlock each lock point, you will emit a shock vibration and sound, and with the unlocking sequence, the vibration and sound will be more obvious. 4 lifting load: if the lock is not unlocked, the load when lifting the main roll is obviously increased or cannot be raised. 5 Observation Spiral

Steps for unlocking the auger drill pipe
The drill pipe of the rotary drilling rig can drill dozens or even hundreds of meters of pile holes. It turns out that the drill pipe is nested inside the drill pipe layer by layer. Today, I will talk to you about the unlocking steps of the spiral drill pipe. Screw unlocking step 1: the most important thing to unlock is the resistance of the drill bucket, and the drill pipe is unlocked by it. this is especially important. screw unlocking step 2: when the resistance of the drill tool is fixed to the core section, the drill pipe and the core section in the third section are unlocked. Step 3 of spiral unlocking: when the core section and the third section are fixed by the resistance of the drilling bucket, the second section and the third section are unlocked. Screw Unlock Step 4: Move
