[0002] With the continuous development of human beings and the increase in population, land resources are becoming increasingly scarce, and land needs to be frequently renovated and rectified. Land reclamation requires reference to local terrain conditions, so it is necessary to collect terrain data for reference. Topographic data requires the use of special data surveying and mapping instruments, and staff carry surveying and mapping instruments to measure and collect data. Since surveying and mapping instruments need to be placed stably and carried, auxiliary devices are required.

[0003] The most commonly used surveying instruments at present are divided into fixed-point scanning and mobile scanning types. The fixed-point scanning equipment is mainly composed of a scanner and a retractable tripod. The scanner and tripod can be installed detachably. When surveying, the staff will open the tripod and stand it on the ground and then fix the scanning instrument to the tripod. The height of the tripod is fixed. When the observation angle of the surveying instrument deviates, the staff can remove the surveying instrument from the tripod and adjust it.

[0004] In the above process, since the height of the tripod is fixed, it is difficult for tall or short staff to use it. Every time the surveying instrument is installed, the observation angle needs to be adjusted before the surveying instrument can be fixed on the tripod. The operation is inconvenient and the angle is not easy to adjust quickly.

[0005] Therefore, a land consolidation project topographic mapping device is proposed to solve the above technical problems. Utility Model Content

[0030] Embodiment 1

[0031] See also Figures 1 to 6 The utility model provides a land consolidation project topographic mapping device, and the technical solution is as follows:

[0032] A land consolidation project topographic surveying and mapping device, comprising: a fixed seat 1, a surveying instrument 3, and a support frame 2, wherein three support frames 2 are provided, and the support frames 2 are rotatably connected to the bottom of the fixed seat 1, and further comprising:

[0033] Sleeve 7, the top of the fixed seat 1 is fixedly connected with a sleeve 7, a sleeve 6 is rotatably installed in the sleeve 7, a rotating shaft 5 is rotatably installed on the top of the sleeve 6 through a flange, and the top of the rotating shaft 5 is detachably connected to the bottom of the surveying instrument 3, a shell 4 is fixedly connected to the side wall of the sleeve 7, the cavity in the shell 4 is connected to the sleeve 7, an adjustment device is arranged in the cavity, a rack 8 and a tooth groove 9 cooperating with the adjustment device are respectively provided on the sleeve 6 and the rotating shaft 5, the sleeve 6 is provided with an opening, the inside of the sleeve 6 is connected with the cavity of the shell 4 through the opening, the tooth grooves 9 are evenly arranged along the side wall of the rotating shaft 5, the adjustment device contacts with the rack 8 and the tooth groove 9 at the opening, when it needs to be raised or lowered, the manual action is performed on the rack 8 through the adjustment device, and the up and down movement of the sleeve 6 is realized by the cooperation of the rack 8 and the adjustment device, and the adjustment device includes:

[0034] A limit rod 10 is slidably mounted on the housing 4, the limit rod 10 passes through the cavity, and one end of the limit rod 10 is fixedly connected to a hand wheel 13;

[0035] Gear 12: Two gears 12 are symmetrically and fixedly connected to the limiting rod 10 at intervals. Both gears 12 are located in the cavity, and the gears 12 are meshed with the rack 8.

[0036] When adjusting the height of the surveying instrument 3, the staff manually holds the hand wheel 13 to adjust the horizontal position of the limit rod 10. At this time, the gear 12 is engaged with the rack 8. The staff manually rotates the gear 12 to drive the rack 8 to move, so that the sleeve 62 moves in the vertical direction, thereby adjusting the surveying instrument 3 in the vertical direction and achieving the purpose of adjusting the height.

[0037] The rack 8 is symmetrically arranged on the side walls at both ends of the opening of the sleeve 6, the side wall of the tooth groove 9 facing one end of the opening is flush with the rack 8, and the two gears 12 are respectively engaged with the two racks 8. When the limit rod 10 rotates, a driving force is generated on both ends of the sleeve 6, so that the sleeve 6 can move smoothly in the vertical direction.

[0038] A slide groove 14 is provided in the cavity of the housing 4, and the slide groove 14 is located at one end close to the handwheel 13. A slider 17 is slidably installed on the slide groove 14, and the slider 17 is sleeved on the limit rod 10 and slides in the direction of the limit rod 10. A clamping rod 15 is fixedly connected to the side wall of the slider 17, and the clamping rod 15 cooperates with the rack 8. A plurality of clamping blocks 18 are arranged at intervals on the side wall of the end of the opening close to the handwheel 13, and chamfers are provided on the upper and lower sides of each clamping block 18 facing the handwheel 13. A push block 16 is fixedly connected to the limit rod 10, and the push block 16 is located between the slider 17 and the handwheel 13 After the surveying instrument 3 is adjusted to a suitable position, the hand wheel 13 is pushed toward the inside of the cavity by hand, and the slider 17 and the clamping rod 15 move along the direction of the slide groove 14. One end of the clamping rod 15 abuts against the bottom of the clamping block 18 to support the clamping block 18, thereby forming a limiting effect on the sleeve 6 in the vertical direction. While realizing the adjustment function, the limiting effect can also be realized. The shortest distance between the gear 12 and the clamping rod 15 is smaller than the longest distance between the rack 8 and the clamping block 18. Each clamping block 18 is aligned with the clamping groove of the rack 8. When the gear 12 is disengaged from the rack 8, the clamping rod 15 is already located between the two clamping blocks 18, thereby preventing the sleeve 6 from sliding greatly and ensuring the stable operation of the device.

[0039] Wheel grooves are evenly formed on the outer side wall of the hand wheel 13 , and the wheel grooves can increase the friction force and facilitate the rotation of the hand wheel 13 by hand.

[0040] Embodiment 2

[0041] This embodiment is optimized on the basis of the first embodiment as an implementation mode of the utility model. The limit rod 10 is provided with a thread 11, and the thread 11 is located between the two gears 12. The thread 11 is meshed with the tooth groove 9. The tooth groove 9 is provided with a plurality of teeth, and the plurality of tooth grooves 9 are evenly arranged along the side wall of the rotating shaft 5. The thread 11 is an annular thread 11, and the annular thread 11 is tangent to the rotating shaft 5. When the hand wheel 13 is pushed by hand to move toward the inside of the cavity, one end of the thread 11 first contacts the tooth groove 9. The thread 11 continues to move in one direction and engages with the tooth groove 9. At this time, the hand wheel 13 is turned manually to rotate the shaft 5, so that the observation angle of the surveying instrument 3 can be adjusted. There is no need to disassemble and reinstall the surveying instrument 3. A limit sleeve 19 for limiting the horizontal movement of the hand wheel 13 is rotatably installed on the outer wall of the shell 4. After adjusting the observation angle, the limit sleeve 19 is rotated to a horizontal position to prevent the hand wheel 13 and the limit rod 10 from sliding outward. The engagement of the thread 11 and the tooth groove 9 has a reverse self-locking function, thereby preventing the shaft 5 from rotating by itself.

[0042] Working principle: transmission is achieved by meshing the gear 12 with the tooth groove 9, so that the surveying instrument 3 moves up and down when the hand wheel 13 is rotated, and the rotation shaft 5 is rotated by meshing the thread 11 with the tooth groove 9, and then the surveying instrument 3 is rotated to adjust the observation angle of the surveying instrument 3. The meshing of the gear 12 and the thread 11 has a reverse self-locking function. As long as the horizontal movement of the limit rod 10 is limited, the rotation of the rotation shaft 5 can be limited, which is more convenient to operate.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
