The drill rod 3 is hollow, and the top end of the rigid rod 113 is connected to the fixing frame 104 through the inside of the drill rod 3 and the gear box 126. The main functions of the driving gear 125 and the driven gear 126 in the gear box 126 are deceleration, namely, the high-rotation-speed and low-torque power of the power device 4 is converted into low-rotation-speed and high-torque power so as to meet the drilling requirements.
According to the inclination measurement while drilling device for the rotary drilling equipment, the verticality of the drill bit 1 and the drill rod 3 can be monitored in real time through the inclination measurement sensor and the azimuth measurement sensor in the rigid rod 113, and the measurement result can be used for checking the monitoring value of the inclination measurement sensor in the sensor cavity 15 on the guide sleeve 11 in real time.
Example 4:
The invention mainly relies on the inclination angle measuring sensor to measure the verticality of the drilling hole, but the inclination angle measuring sensor generally has calibration errors, so that the measurement result is distorted. The embodiment is a device for measuring the inclination of the multi-axis rotary drilling equipment while drilling, which can realize the accurate checking of the verticality of a drill rod and eliminate the influence of sensor measurement errors caused by factors such as calibration of an inclination angle measurement sensor in the checking process.

As shown in fig. 17, since the buoyancy of floating body 213 is always vertically upward, when floating body 213 is stationary, the downward pulling force applied to floating body 213 by wire rope 211 is necessarily equal in magnitude and opposite in direction.

Since the steel wire rope 211 is absolutely vertical, the measured deviation degree of the steel wire rope can not generate phenomena such as zero drift of a general inclination angle sensor, and parameter calibration is not needed, so that the monitoring value of the inclination angle sensor is checked by using the monitoring value in the embodiment, and the influence of sensor measurement errors caused by factors such as calibration of the inclination angle measurement sensor can be eliminated.
