Technical Field
[0001] The utility model relates to the technical field of land surveying and mapping, in particular to a leveling mechanism for an instrument support used in land surveying and mapping. Background Technique
[0002] Land surveying and mapping refers to the work of measuring and mapping the quantity, distribution, topography and other characteristics of various lands by using surveying and remote sensing technology methods. It includes topographic surveying, cadastral surveying, land leveling surveying, current land use surveying, investigation of reserve resources such as barren mountains and wastelands, etc. During the process of using instruments to survey and map land, in order to ensure the accuracy of the surveying and mapping results, it is necessary to ensure that the instrument is in a normal horizontal state. However, affected by the undulation of the terrain, in many cases, after the instrument support is placed, it still needs to be leveled to provide a horizontal support for the work of the instrument. In the prior art, the instrument support mostly adopts a tripod. In order to adapt to the uneven ground environment, the legs of the instrument support can often be adjusted in length, and the instrument mounting platform is kept horizontal on the uneven ground by using legs of different lengths. However, the support effect will be affected after the leg length of some instrument supports is changed, and the leveling knobs of most instrument supports are set in the middle of the legs, which is far from the instrument mounting platform, and the leveling process is more inconvenient.

The universal ball 21 is rotatably connected to the universal ball groove 23. The adjusting columns 26 are respectively vertically slidably connected in the grooves on the surface of the support platform 1. The three adjusting columns 26 are annularly distributed with the universal ball 21 as the center. The semi-circular ends at the upper ends of the adjusting columns 26 are fitted and installed with the leveling plate 22. By moving the adjusting columns 26 up and down, an upward acting force is applied to the leveling plate 22, pushing the universal ball 21 to rotate in the universal ball groove 23 to adjust the angle of the leveling plate 22. When the leveling plate 22 is adjusted to a horizontal position, the adjusting assembly 2 further includes a relief chute 24 and a sliding column 25. The relief chute 24 is arranged in the middle of the universal ball 21. The sliding column 25 is arranged between the front and rear inner walls of the universal ball groove 23. The sliding column 25 is slidably connected between the left and right inner walls of the relief chute 24. By the sliding column 25 rotating and sliding in the relief chute 24, the rotation of the leveling plate 22 is restricted. A chute 3 is provided on the lower surface of the adjusting column 26. Guide sliding columns 4 are provided on the bottom walls of the grooves on the surface of the support platform 1. The guide sliding columns 4 are vertically slidably connected to the chute 3 to limit the moving range of the adjusting column 26 and at the same time limit the rotation of the adjusting column 26. The lower ends of the adjusting columns 26 are all threaded columns. Internal thread rings 5 are threadedly connected to the outer arc surfaces of the adjusting columns 26. The internal thread rings 5 are respectively located in the rotating grooves inside the support platform 1. Worm wheels 6 are provided on the outer arc surfaces of the internal thread rings 5. Worm shafts 7 are respectively rotatably connected inside the support platform 1. The worm shafts 7 are meshed with the worm wheels 6.

According to the detection result, the indicator light 12 is started, and the light emitted by the indicator light 12 is used to indicate the operator to rotate the knob 8 at the specified position.
[0022] The working principle of a leveling mechanism for an instrument support used in land surveying provided by the present utility model is as follows: During use, a land surveying instrument is installed on the upper surface of the leveling plate 22. The support platform 1 is fixed to the upper end of the instrument support. When the leveling plate 22 is tilted, the worm 7 is rotated by turning the knob 8. Through the meshing connection between the worm 7 and the worm gear 6, the worm gear 6 drives the internal thread ring 5 to rotate. Through the threaded connection between the internal thread ring 5 and the adjusting column 26, under the limiting and guiding of the guiding slide column 4, the adjusting column 26 is driven to move up and down. An upward acting force is applied to the leveling plate 22 by the semi-circular end of the adjusting column 26 to push the leveling plate 22 to rotate. The universal ball 21 rotates in the universal ball groove 23, and the slide column 25 rotates and slides in the relief chute 24. By the cooperation of the three adjusting columns 26, the tilt angle of the leveling plate 22 is adjusted, and the leveling plate 22 is adjusted to a horizontal position to ensure the accuracy of the land surveying instrument detection.
