[0025] Working principle:

[0026] When performing directional high-position grouting drilling, the staff first moves the equipment body 1 to the position where the drill bit is required. After completion, the staff observes the level ruler 8 to see whether the bubble inside the level ruler 8 is located in the middle of the level ruler 8. If the bubble is in the middle of the level ruler 8, it means that the drill bit 11 is in a horizontal position. If the bubble is at the right end of the level ruler 8, the staff rotates the leveling device 5. If the bubble is at the left end of the level ruler 8, the staff rotates the leveling device 5 in the opposite direction to adjust the drill bit 11 to a horizontal state. After completion, the staff rotates the limit device 9 to limit the leveling device 5, connects the motor 10 to an external power supply, and the motor 10 drives the drill bit 11 to rotate. At the same time, the two hydraulic cylinders 2 are started.
