[0037] The working principle of the present invention is as follows:

[0038] The mobile device 1 is placed in the mine tunnel, and the movement of the mobile device 1 drives the measuring instrument 2 fixed at the front end to measure up and down. The device can adapt to uneven ground and adjust the height and rotation direction of the measuring instrument 2 in real time;

[0039] Principle of measuring height adjustment: In the sliding device 12, by starting the motor 121, the pushing rod 123 fixedly connected at both ends of the top of the long plate 122 is driven to move upward, and then the pushing rod 123 will push the movable plate 124 to rise. Since the inner side of the movable plate 124 is movably connected to the outer side of the connecting plate 115, when the movable plate 124 continues to rise in height, the first elliptical plate 125 connected to the outer side of the movable plate 124 will drive the rotating plate 126 to swing forward, allowing the rotating plate 126 and the first rotating shaft 127 to adjust the direction under the torsion of the outer surface of the rotating column 116, thereby driving the square plate 128 fixedly connected to the front end of the rotating plate 126 and the fixing device 129 to flip the direction, thereby realizing the measurement of different directions of the measuring instrument 2.

Since the front end of the connecting plate 115 is fixedly connected to the rear end of the sliding device 12, the sliding device 12 can move synchronously with the connecting plate 115, and finally adjust the measuring height of the measuring instrument 2;

[0040] Fixing principle of measuring instrument: the fixing device 129 includes a double-rod cylinder 1291, which drives two semicircular blocks 1292 to move left and right. When the double-rod cylinder 1291 pulls the semicircular blocks 1292 to expand to both sides, the second elliptical plate 1294 at the groove of the semicircular block 1292 rotates under the second rotating shaft 1293, which drives the movably connected gripper 1295 at the other end to deviate toward the center, thereby clamping the two sides of the measuring instrument 2 to prevent it from loosening during movement;

[0041] Balancing principle of the device: The balancing device 13 can adapt to different ground levels through the linkage of the polygonal block 133, the curved rod 135 and the triangular support block 137. The curved rod 135 will perform the first angle adjustment under the action of the third rotating shaft 134, and fold the curved part at the higher ground; at the same time, the triangular support block 137 will perform a second folding through the rotation of the fourth rotating shaft 136, raising the lower ground to ensure that the balancing device 13 remains horizontal as a whole and prevents tilting. The entire device can achieve multi-faceted adjustments to the height adjustment, multi-angle measurement, fixing and balancing functions of the measuring instrument 2, thereby adapting to different ground environments and ensuring stability and accuracy during the measurement process.
