The pressure of the rotary drilling rig lock rod is interlocked by the concave key bar on the drill rod to form a rigid connection, which transmits the pressure and no longer depends on the load of the bucket. Compared with the friction drill pipe, it can transmit a larger axial pressure. As long as the quality and center of gravity of the whole machine is reasonable, a theoretically set maximum pressure can be output.

Features
1.The rig has the function of high and low speed of the power head. It can use high-speed up / down when slagging and finding the lock point, so as to quickly find the lock point.When reversing and unlocking, the current power head position is marked with reference to the mast. When the second drill is performed, the power head is raised to the marked position in advance to achieve rapid machine lock.When the power head machine lock reaches the bottom of the mast, it is necessary to re-lift the power head and the next machine lock point machine lock. Because the tube is hidden inside (except the first section), the power head lifting height can refer to the first section No. 1 to 2 No. pressure table spacing.
2.Machine lock lever unlocking: The stroke of the machine lock table is longer than the length of the drive key, so the drill pipe swivel is suspended. Lift the power head before unlocking to eliminate the suspension stroke, and also reduce the friction between the drive key and the lock point; When the bucket has a drilling load, it reverses. The core is fixed by the resistance of the drill. The other sections of the drill rod and power head are reversed. Each drive key is separated from the lock point and returned to the key slot position.
