Abstract
The invention discloses a device and a method for measuring the drill hole inclination of a rotary drilling rig. The device comprises a wireless inclinometer while drilling and an inclination measuring terminal, wherein the wireless inclinometer while drilling is arranged on a drill rod of the rotary drilling rig and is used for measuring the inclination of the drill rod, which is provided with a time mark, so as to represent the inclination of a corresponding drill hole; the inclination measuring terminal is matched with the wireless inclinometer while drilling, and is used for receiving the inclination of the drill hole sent by the wireless inclinometer while drilling in a wireless transmission mode, transmitting the inclination of the drill hole to a vehicle-mounted display for real-time display through a controller area network (CAN) bus, also judging whether the inclination of the drill hole exceeds a preset inclination threshold value, and outputting an alarm signal to the vehicle-mounted display if the inclination of the drill hole exceeds the preset inclination threshold value; therefore, the inclination of the drill hole is measured while drilling one line. Moreover, because the wireless inclinometer while drilling is arranged on the drill rod, when the drill rod inclines, a drill hole inevitably inclines correspondingly, and the inclination condition of the drill hole can be objectively and really reflected.
