Description

Technical Field

[0001] This utility model relates to the field of auxiliary measurement technology for coal mine roadway excavation, and in particular to a mine digital display laser orientation instrument. Background Technology

[0002] In coal mine roadway excavation, centerline and waistline markers are always present to indicate the direction of excavation. The traditional method involves workers installing a laser pointer at a fixed location according to coal mine surveying regulations. Three fixed points are then selected in front of the laser pointer, each with a rope suspending a plumb bob. The laser beam is repeatedly passed through all three ropes to ensure the roadway centerline's position and direction meet design requirements. The distance from the laser beam to the top and bottom of the roadway is measured using a ruler or rangefinder, or the slope is indicated by a slope gauge to confirm the waistline's position and direction. This method typically requires three or more workers, involves repeated operations and measurements to ensure accuracy, and is both labor-intensive and time-consuming, impacting work efficiency.

After attitude calculation, no angular drift is achieved on the X and Y axes, and no angular drift is achieved on the Z axis in a stationary state. This allows for the measurement of high-precision attitude data from a stationary to a moving environment. The laser emitter 202 and the deviation sensor 2 are mature existing technologies and will not be described in detail here.

[0032] The detection component 2 is equipped with a tilt angle rotation fine-tuning component 9, which is used to precisely adjust the pitch angle of the detection component 2.

[0037] When precise adjustment of the horizontal rotation angle of the laser emitter 202 in the detection assembly 2 is required, the initial adjustment is a relatively large one: Tighten the second stop screw 1506 to loosen it from the second clamping block 1505, and then loosen the second clamping block 1505 from the short shaft of the flange shaft 1501. Rotate the body seat 1502, and then rotate the detection assembly 2 to adjust the horizontal rotation angle of the laser emitter 202. At this time, the second rotating wheel 1504 and the short shaft of the flange shaft 1501 are in clearance fit, and the second rotating wheel 1504 is stationary. The horizontal rotation angle of the laser emitter 202 can be adjusted to a large extent; secondly, it can be precisely fine-tuned: turn the second stop screw 1506 so that the second stop screw 1506 abuts against the second clamping block 1505, and the second clamping block 1505 abuts against the short shaft of the flange shaft 1501.

Figure 9 , Figure 10 The posture shown can be adjusted by rotating the device according to the site conditions in practical applications.

[0041] The following is Figure 9 The application is described in the following description. Several anchor bolts 1 are fixedly installed on the top of the mine tunnel. The third clamping seat 6 is clamped onto the anchor bolts 1. The laser emitter 202 on the detection component 2 is oriented towards the direction of excavation in the mine tunnel. Based on the laser calibration mark emitted by the laser emitter 202, the first clamping seat 16 and the second clamping seat 18 are rotated to initially adjust their positions. The next step is to precisely adjust the position of the laser calibration mark. The positions of the tilt rotation fine-tuning component 9 and the horizontal rotation fine-tuning component 15 are adjusted to bring the laser calibration mark to the specified data position. During the adjustment process, the level can be adjusted according to the indications of the first bubble level 12 and the second bubble level 13. The position of the laser calibration mark is precisely adjusted according to the data detected by the deviation sensor 203 and displayed in real time on the display 10. After the adjustment is completed, the excavation work can be carried out according to the calibration indication. When the excavation direction of the tunnel changes or the position of the laser calibration mark shifts due to factors such as machine vibration, the real-time detection data on the display 10 will trigger an alarm, requiring recalibration. At this point, the position of the device can be coarsely or finely adjusted according to the actual situation, and the excavation work of the mine tunnel can continue after the adjustment.
