Description

Technical Field

[0001] The utility model relates to the technical field of drilling rig hole orientation, in particular to a self-north-seeking laser pointing hole orientation instrument in underground coal mines. Background Art

[0002] In the prior art, conventional rotary drilling and orientation in coal mines usually use a tracker based on magnetic sensors as the basis for azimuth measurement to measure the trajectory of the entire borehole in order to obtain accurate trajectory measurement data. However, when the drill rig is drilling a hole, the drill rig is surrounded by a large amount of ferromagnetic material, which makes it impossible for the tracker to accurately measure the hole position. Therefore, a hole drilling orientator is usually used to orient the drill rig before drilling. The hole drilling orientator is generally implemented using two technical solutions. One is to use the azimuth line introduced into the coal mine as a reference, align the hole drilling orientator parallel to the azimuth line, and then input the azimuth line information into the hole drilling orientator to obtain the north direction, and then use the acceleration sensor and gyroscope sensor inside the orientator to measure the inclination and azimuth of the hole drilling position. The other is to use a magnetic sensor in an open position in the coal mine. The magnetic north direction is measured in a relatively non-magnetic environment, and then the inclination and azimuth of the opening position are measured by the accelerometer and gyro sensor inside the orientation instrument. The gyro sensor in the above two schemes cannot realize the self-seeking north function, and the north direction is obtained by introducing the azimuth line or the magnetic north measured by the magnetic sensor. The two schemes have the problem of introducing the azimuth line or failing to obtain a relatively non-magnetic environment, resulting in low accuracy of the north direction. In addition, the hole orientation instrument is generally installed at the fixture position, which is a certain distance away from the hole position, and cannot obtain accurate inclination and azimuth data of the hole position. In actual applications, it is found that the above equipment only solves the simple and inefficient hole orientation function, cannot realize the self-seeking north function, and cannot be waterproof and dustproof. This hole orientation method is not only inefficient, but also easily damaged by dust and water vapor, and cannot adapt to more underground mine environments. Utility Model Content

[0003] In order to solve the problem that the north direction is not accurate enough in the prior art and the inclination and azimuth data of the opening position cannot be obtained accurately, it is necessary to design a device and method to solve the above problems.

[0007] Furthermore, an up-select button, a down-select button, a return button, a confirm button, and a switch button are arranged on the top of the button unit.

[0008] Furthermore, the shell is provided with a through hole, and the laser pointing unit and the shell are connected to the through hole by bolts. An O-ring is inserted and installed on the side wall of the laser pointing unit. The O-ring fits tightly with the laser pointing unit and the side wall of the shell.
