DETAILED DESCRIPTION

The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

1-2, the utility model provides an embodiment: a surveying and mapping support of a surveying and mapping instrument, comprising a surveying and mapping instrument body 1 and a U-shaped frame 2, the surveying and mapping instrument body 1 is rotatably mounted on the inner wall side of the U-shaped frame 2, the surveying and mapping instrument body 1 can be rotated up and down in the vertical direction, thereby improving the surveying and mapping range of the surveying and mapping instrument body 1, a cylindrical base 3 for supporting the surveying and mapping instrument body 1 is fixedly connected to the bottom of the U-shaped frame 2, a surveying and mapping support assembly is arranged at the bottom of the cylindrical base 3, the surveying and mapping support assembly comprises a disc 4, a clamping assembly is arranged at the top of the disc 4, a supporting assembly is arranged at the bottom of the disc 4, a level bubble meter 20 is fixedly connected to the upper surface of the disc 4, the level bubble meter 20 is a prior art, and the disc 4 can be horizontally calibrated by observing the level bubble meter 20.

Referring to Figures 3 to 5, further, the clamping assembly includes a sleeve 5 and a rack 6. The sleeve 5 is fixedly installed on the top of the disc 4. The central axis of the sleeve 5 coincides with the central axis of the disc 4 to ensure that the position of the internally fixed surveying instrument body 1 is not offset. The rack 6 penetrates and slides on the inner wall of the sleeve 5 to ensure the stability of the rack 6 sliding on the sleeve 5. One end of the rack 6 is fixedly connected to a clamping block 7. The inner groove of the clamping block 7 matches the outer surface of the cylindrical base 3. The side of the clamping block 7 away from the rack 6 contacts the circumferential surface of the cylindrical base 3. The clamping block 7 can clamp the surveying instrument body 1 The clamping block 7 can hold the surveying instrument body 1, and before the clamping block 7 clamps the surveying instrument body 1, the horizontal surveying angle of the surveying instrument body 1 can be changed by changing the angle of the cylindrical base 3 in the sleeve 5, which can adapt to different surveying and mapping work needs. The clamping assembly also includes a gear 8, a rotating shaft 9 and a gear 2 10. The gear 1 8 is meshed with the rack 6, and the gear 1 8 drives the rack 6 to move. The rotating shaft 9 is fixedly mounted on the inner wall of the gear 1 8, and the rotating shaft 9 passes through and is rotatably mounted on the inner wall of the disk 4. The gear 2 10 is fixedly mounted on the bottom of the outer surface of the rotating shaft 9, and the angular velocity of the gear 1 8 and the gear 2 10 when rotating is the same.

Referring to Figures 4 to 6, further, the clamping group also includes an inner gear ring 11, which is rotatably mounted on the bottom of the disc 4, and the inner gear ring 11 is meshed with the gear 2 10. The clamping assembly also includes a gear 3 13, and the gear 3 13 is meshed with the inner gear ring 11 through teeth 12, and the teeth 12 are fixedly mounted on the outer surface of the inner gear ring 11. The gear 3 13 drives the inner gear ring 11 to rotate. Since the gear 3 13 is much smaller than the inner gear ring 11, the clamping block 7 can move slowly to clamp the cylindrical base 3, reduce the impact force on the surveying and mapping instrument, and avoid damage to the surveying and mapping instrument. The gear 3 13 The rotating shaft is rotatably mounted at the bottom of the disc 4, and the rotating shaft of the gear three 13 is fixedly connected to a worm wheel 14 at one end away from the disc 4. When the worm wheel 14 rotates, the gear three 13 can be driven to rotate. The clamping assembly also includes a stepping motor 15 and a worm 16. The stepping motor 15 is fixedly mounted at the bottom of the disc 4. The stepping motor 15 can accurately control the rotation angle of the output shaft. The worm 16 is fixedly mounted on the output shaft of the stepping motor 15. The worm 16 is meshed with the worm wheel 14. Through the cooperation of the worm 16 and the worm wheel 14, the worm wheel 14 cannot drive the worm 16 to rotate in the reverse direction, so that the clamping is more stable.

Referring to Figures 1, 5 and 7, further, the support assembly includes a support leg 17 and a fixed cone 19. The support leg 17 is rotatably installed at the bottom of the disc 4 through a hinge. The support leg 17 plays the role of supporting the disc 4. The top of the fixed cone 19 is fixedly connected with a threaded rod 18. When working in the field, the bottom of the fixed cone 19 is inserted into the ground to stabilize the bottom of the support leg 17. A threaded hole is provided at the bottom of the support leg 17, and the threaded rod 18 is threadedly installed in the threaded hole. The length of the support leg 17 is controlled by controlling the rotation angle of the threaded rod 18, thereby controlling the height of the disc 4 from the ground.

Working principle: when in use, the staff first places the surveying and mapping bracket assembly firmly on the ground through the support assembly. The working method of the support assembly will be described in detail below. Then the staff puts the cylindrical base 3 at the bottom of the U-shaped frame 2 into the sleeve 5, and then starts the power supply of the stepper motor 15. The stepper motor 15 drives the worm 16 to rotate, and the rotation of the worm 16 drives the worm wheel 14 to rotate. The rotation of the worm wheel 14 drives the gear three 13 to rotate. The rotation of the gear three 13 drives the inner gear ring 11 to rotate. The rotation of the inner gear ring 11 drives the gear two 10 to rotate. The rotation of the gear two 10 drives the rotating shaft 9 to rotate. The rotation of the rotating shaft 9 drives the gear one 8 to rotate. The rotation of the gear one 8 drives the rack 6 to make a linear motion in the direction close to the sleeve 5. The movement of the rack 6 drives the clamping block 7 to move and squeeze the cylindrical base 3 inside the sleeve 5, thereby completing the fixation of the cylindrical base 3, so that the surveying and mapping instrument body 1 above the U-shaped frame 2 is more firmly fixed on the disc 4, thereby improving the accuracy of surveying and mapping.

When the staff places the surveying and mapping bracket assembly on the ground through the support assembly, first rotate the support leg 17 to a suitable angle, then install the threaded rod 18 on the top of the fixed cone 19 into the threaded hole at the bottom of the support leg 17, and then observe the level bubble meter 20 on the disc 4 to check whether the disc 4 is in a horizontal state. According to the feedback from the level bubble meter 20, the staff makes slight adjustments to the angle of the support leg 17 and the distance between the fixed cone 19 and the support leg 17 until the disc 4 is in a horizontal state. Finally, the staff completes the fixation of the surveying and mapping assembly through the clamping assembly and can start the surveying and mapping work. It can adapt to a variety of terrains and reduce the impact and limitations of complex terrain on surveying and mapping work.

Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
