Description

Technical Field

[0001] The utility model relates to the technical field of gyro total stations, in particular to a leveling device for a gyro total station. Background Art

[0002] The gyro total station is a precision measuring instrument used for gyro orientation in modern coal mines. It has the characteristics of simple operation, high precision and short operation time. However, the use and transportation of the instrument also have strict requirements. The gyro total station needs to be adjusted to a horizontal state to ensure the accuracy of the measurement results. Otherwise, the gyro may be damaged or the north-seeking accuracy of the gyro total station may be affected. Therefore, the leveling of the gyro total station has become a major factor that surveyors have to consider when using the gyro total station.

[0003] A search revealed a high-precision gyro total station calibration device with patent publication number CN218270790U that states, "When a lateral tilt occurs, gravity causes the rotating shaft to rotate, thereby driving the gyro total station to rotate laterally, thereby automatically calibrating and leveling it. Thus, through the coordinated rotation of gravity, the turntable and the rotating shaft, the gyro total station achieves an automatic leveling and calibration effect similar to a tumbler. During transportation, due to its automatic vertical calibration function, it can automatically rotate and calibrate during transportation, ensuring that the tilt angle of the gyro total station body remains within 30 degrees, thereby improving transportation convenience."

[0004] However, the above scheme still has certain shortcomings in actual use. The above scheme uses the gravity factor to enable the gyro total station to achieve the effect of automatic leveling calibration, but this leveling method is a passive calibration, which makes the calibration accuracy poor, thereby affecting the subsequent measurement accuracy of the gyro total station.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-4 The utility model discloses a leveling device for a gyro total station, comprising a support structure 1, a calibration structure 2 is provided at the top of the support structure 1, and a gyro total station body 3 is provided at the center of the calibration structure 2.

[0022] The support structure 1 includes a support rod 101 , three side rods 102 are hingedly connected to the outer side of the support rod 101 , and a connecting rod 103 is hingedly connected between the support rod 101 and the side rods 102 .

[0023] The calibration structure 2 includes a driving platform 201, a lifting rod 202 is fixedly installed at the center of the driving platform 201, the top of the lifting rod 202 is hinged with a mounting ring 203, a spirit level 204 is provided on the outside of the mounting ring 203, and four groups of adjustment structures 205 are provided at the top of the driving platform 201, and the movable ends of the adjustment structures 205 are connected to the bottom end of the mounting ring 203.

[0024] The adjustment structure 205 includes an adjustment box 207, the inner wall of the adjustment box 207 is rotatably connected to a drive screw 208 through a built-in motor, the surface of the drive screw 208 is threadedly connected to a threaded ring 211, the top of the threaded ring 211 is rotatably connected to a hinged rod 212, the top of the hinged rod 212 is hinged to a lifting plate 213, the top of the lifting plate 213 is fixedly installed with a pushing ball rod 214, and the top of the pushing ball rod 214 is connected to the bottom end of the mounting ring 203.

[0025] By setting up the calibration structure 2, the lifting ball rod 202 can be used to assist in lifting the gyro total station body 3 through the mounting ring 203, and then in conjunction with the four adjustment structures 205, the mounting ring 203 can be gradually made parallel to the placement surface through the level 204, so that the gyro total station body 3 is actively leveled, which significantly improves the calibration accuracy of the gyro total station body 3, thereby ensuring the subsequent measurement accuracy of the gyro total station.

[0026] Specifically, a sleeve gear 209 is fixedly sleeved on the surface of the driving screw 208 , and the inner wall of the regulating box 207 is slidably connected to a limit rack 210 through an electric push rod, and the sleeve gear 209 and the limit rack 210 are meshed with each other.

[0027] In this embodiment, when the driving screw 208 needs to be locked, the electric push rod drives the limiting rack 210 to gradually fit with the socket gear 209, so that the limiting rack 210 and the socket gear 209 are engaged, so that the socket gear 209 limits the rotation of the driving screw 208.

[0028] Specifically, five plug-in rings 206 are provided at the bottom end of the mounting ring 203 , and the lifting club 202 and the pushing club 214 are movably connected to the bottom end of the mounting ring 203 through the plug-in rings 206 .

[0029] In this embodiment, the plug-in ring 206 can be used to connect the lifting club 202 and the pushing club 214 to the bottom end of the mounting ring 203, so that the movable connection effect of the lifting club 202 and the pushing club 214 and the mounting ring 203 is significantly improved.

[0033] At this time, the staff begins to observe whether the level meter 204 is in a horizontal state. When the level meter 204 is not in a horizontal state, the staff selectively opens the adjustment structure 205 at the location where the tilt degree is the largest according to the tilt state of the level meter 204 at this time.

[0034] The built-in motor starts to drive the driving screw 208 to rotate, causing the teeth on the surface of the driving screw 208 to drive the threaded ring 211 to perform threaded tooth dislocation movement, causing the threaded ring 211 to start axial movement along the surface of the driving screw 208, causing the threaded ring 211 to drive the hinge rod 212 to adjust the angle, causing the hinge rod 212 to drive the lifting plate 213 to adjust the height, causing the lifting plate 213 to drive the pushing rod 214 to move synchronously, causing the pushing rod 214 to drive the mounting ring 203 to adjust the angle through the plug ring 206;

[0035] The placement state of the mounting ring 203 is adjusted, driving the level 204 to gradually move toward a horizontal state, thereby completing the adjustment process.

[0036] To sum up, the leveling device for the gyro total station, by setting up the calibration structure 2, can assist in lifting the gyro total station body 3 through the mounting ring 203 using the lifting ball rod 202, and then cooperate with the four adjustment structures 205 to gradually make the mounting ring 203 parallel to the placement surface through the spirit level 204, so that the gyro total station body 3 is actively leveled, which significantly improves the calibration accuracy of the gyro total station body 3, thereby ensuring the subsequent measurement accuracy of the gyro total station.
