[0032] Furthermore, the vertical guide lifting drive assembly includes an electric telescopic rod 14 fixedly installed on the right side of the top of the base plate 3, the extended end of the electric telescopic rod 14 is fixedly connected to the bottom of the positioning seat 7 on the right side, and two vertical guide rods 15 are fixedly connected to both sides of the top of the base plate 3. The circular shield 2 is slidably sleeved on the four vertical guide rods 15, wherein two vertical guide grooves are provided on both sides of the bottom of the circular shield 2, and the inner walls of the vertical guide grooves are slidably sleeved with the outer sides of the corresponding vertical guide rods 15, which plays the effect of guiding the vertical sliding of the circular shield 2. The four corners of the top of the base plate 3 are fixedly connected with supporting feet, and the front sides of the multi-stage electric push rods 16 and the electric telescopic rods 14 are fixed and electrically connected. A wireless remote control switch is connected, and the two wireless remote control switches are matched with the same external remote control, which allows personnel to remotely open and close the multi-stage electric push rod 16 and the electric telescopic rod 14. A battery located in the circular shield 2 is fixedly connected to the right side of the top of the bottom plate 3. The multi-stage electric push rod 16 and the electric telescopic rod 14 are electrically connected to the battery, which provides power for the multi-stage electric push rod 16 and the electric telescopic rod 14; the electric telescopic rod 14 and the vertical guide rod 15 are coordinated, and the electric telescopic rod 14 is used to drive the circular shield 2 to rise and fall to adjust the use height through the positioning seat 7 on the right, and the four vertical guide rods 15 are used to vertically guide the circular shield 2.

[0033] The method of using this embodiment is as follows: when the surveying instrument 1 needs to be moved out for use during mine surveying and mapping work, the personnel use the external remote control to control the multi-stage electric push rod 16 to start forward, so that it drives the lifting plate 5 to move upward, and the lifting plate 5 drives the arc cover plate 4 to rise in turn through the four T-shaped guide rods 6 and the four buffer springs 9. At the same time, the lifting plate 5 drives the surveying instrument 1 to move out upward in turn through the ball sleeve 10, the universal ball 11 and the connecting seat. At this time, the surveying instrument 1 can be used for mine surveying and mapping work, so that it is convenient to automatically control the surveying instrument 1 to be moved out when in use;

[0034] When the use height of the surveying instrument 1 needs to be adjusted, the electric telescopic rod 14 is started forward to drive the positioning seat 7 on the right side to move upward, and the positioning seat 7 on the right side drives the circular shield 2 to slide upward on the four vertical guide rods 15, and the circular shield 2 drives the surveying instrument 1 to move upward through the multi-stage electric push rod 16, the lifting plate 5, the ball sleeve 10, the universal ball 11 and the connecting seat in turn, so as to change its height, so as to facilitate the use height adjustment of the surveying instrument 1 according to the use requirements;

[0035] When the ground is uneven and the whole body is tilted, and the surveying instrument 1 needs to be leveled or the direction is adjusted, the T-shaped pressing bolt 13 is rotated in the opposite direction to make it move to the right and release the lock of the universal ball 11. At this time, under the action of its own gravity, the counterweight block 12 automatically rotates vertically and drives the universal ball 11 to rotate adaptively. At this time, the universal ball 11 drives the surveying instrument 1 to automatically rotate to the horizontal through the connecting seat, so as to achieve the effect of blindly leveling the surveying instrument 1 quickly by means of counterweight. By means of blind leveling, the leveling efficiency and convenience are improved. When adjusting the direction, the surveying instrument 1 can be directly rotated horizontally to drive the universal ball 11 to rotate horizontally through the connecting seat. After the horizontal direction is adjusted, the T-shaped pressing bolt 13 is rotated forward to press the universal ball 11 to the left.

[0036] In the surveying and mapping work, the arc cover plate 4 provides real-time safety protection against falling objects on the upper part of the surveying and mapping instrument 1. When the surveying and mapping instrument 1 is accidentally impacted by falling objects, the arc cover plate 4 moves downward under the impact. At this time, the arc cover plate 4 drives the four sliding sleeves 8 to slide downward on the corresponding T-shaped guide rods 6 respectively, and compresses the buffer spring 9. The elastic force of the buffer spring 9 is used to achieve buffering and unloading when the upper part is impacted by falling objects, thereby reducing the transmitted hard shock impact force, achieving the effect of real-time safety protection against falling objects on the upper part of the surveying and mapping instrument 1 when in use, reducing the risk of damage to the surveying and mapping instrument 1 by the impact of falling objects during long-term surveying and mapping work, and improving safety during use;

[0037] After use, the multi-stage electric push rod 16 and the electric telescopic rod 14 are started in reverse. The electric telescopic rod 14 drives the circular shield 2 to move back and reset downward through the positioning seat 7 on the right to lower the height, thereby reducing the occupied height volume. The multi-stage electric push rod 16 drives the lifting plate 5 to move downward. Similarly, the movement direction of the lifting plate 5 is completely opposite to the upward movement of the above-mentioned lifting plate 5. At this time, the arc cover plate 4 and the surveying and mapping instrument 1 are both transformed into moving back and reset downward, and the surveying and mapping instrument 1 is stored downward into the circular shield 2. The arc cover plate 4 shields the top of the circular shield 2, thereby achieving the effect of automatically storing and protecting the surveying and mapping instrument 1 safely after use, reducing the risk of accidental damage to the surveying and mapping instrument 1 during temporary carrying, and facilitating safe and integrated carrying.
