In the construction, a multi-arm rock drilling rig is generally used for drilling. In the drilling, the drill arm is first adjusted to the approximate position of the hole to be drilled by the rig driver, then the measurement personnel enter the high-altitude service basket, and after the high-altitude service basket is controlled to the appropriate position, a self-made triangular ruler is used to measure the drilling angle of the drill arm, and the measurement result is fed back to the rig driver. The rig driver adjusts the angle of the drill arm according to the measurement feedback result. After multiple measurements and adjustments, the angle of the drill rod and the rock surface finally meets the design requirements.

Specifically, the horizontal rod 3 and the inclined rod 4 are welded and fixed or fixedly connected through screws.

[0028] The inclined rod 4 is provided with an angle scale 8 for measuring the angle between the inclined rod 4 and the horizontal rod 3. Specifically, the angle scale 8 is fixed on the inclined rod 4 through a connecting steel sheet 9, the straight edge of the angle scale 8 is parallel to the horizontal rod 3, and the center point of the angle scale 8 is located on the axis of the inclined rod 4, so that the construction personnel can quickly read the inclination angle of the inclined rod 4 and the horizontal rod 3 according to the angle scale 8.

Multi-arm trolley starts to drill into the anchor rod hole, the driver can clearly see the inclined surface formed by the rays of the plurality of laser pens, and controls the direction and position of the drill arm, directly adjusts the drill rod to the inclined surface, so that the drill rod blocks all the laser rays, and the inclination angle of the drill rod is consistent with the preset drilling angle, and then starts to drill. In the drilling process, when the position of the drill rod changes, the position of the drill rod can be adjusted in real time.
