Description

Technical Field

[0001] The utility model relates to the technical field of positioning and mapping devices, in particular to a positioning and mapping device for terrain mapping azimuth. Background Art

[0002] Topographic azimuth refers to the angle of direction of an object relative to geographic north in topographic surveying. This azimuth can help determine the position of an object on the earth's surface and plays an important role in areas such as map making, navigation, and engineering surveying. Positioning surveying devices that use topographic azimuth are designed to accurately determine the position and direction of objects. By measuring the angle between an object and geographic north, the position of the object can be located in the correct position on the map and provide an accurate reference in navigation and engineering surveying. This device is usually equipped with various sensors and measuring equipment, such as a global positioning system (GPS), an inertial navigation system (INS), and a magnetic compass, to ensure the accuracy and reliability of the measurement results.

[0003] In most cases, the existing positioning and surveying devices are used to install the surveying instruments on the bracket by means of bolts and nuts. However, when the instrument needs to be transported or disassembled for maintenance, it is usually necessary to use installation and disassembly tools to install and disassemble the bolts and nuts. However, the above operation method is not only cumbersome but also easy to affect the progress of the staff's surveying and mapping work, thereby greatly reducing the practicality of the device.

[0008] Furthermore, a rack column is slidably connected to an inner wall of the sleeve, and a positioning pin is rotatably connected to the lower surface of the rack column.

[0009] Furthermore, a bolt is rotatably connected to one side of an outer wall of the sleeve, a gear is fixedly connected to the middle of the outer wall of the bolt, the gear is meshed with the rack column, and a nut is threadedly connected to the outer wall of the bolt.

[0010] Furthermore, a second sleeve is slidably connected to the outer wall of the screw rod, a threaded sleeve is rotatably connected to the upper surface of the second sleeve, and the threaded sleeve is threadedly connected to the screw rod.

By starting the electric push rod, the clamping plate 2 is pushed to further clamp the two sides of the surveying and mapping instrument, thereby achieving the effect of further stabilizing the instrument. Compared with the prior art, the installation speed is improved and the practicality of the device is increased.

[0023] Specifically, first, place the instrument on top of the mounting table 1, and then, by rotating the rod 3, the worm 4 is tightly meshed with the worm wheel 2. This step achieves the effect of driving the multiple arc plates 6 on the outer wall of the turntable 5 to rotate. The arc plate 6 can easily drive the clamping plate 1 8 to clamp the instrument, thereby achieving the goal of stably installing the instrument. Then start the electric push rod 1001, and through the movement of the electric push rod 1001, drive the fixed rod 13 on the inner wall of the hinge block 1002 to move. Next, the movement of the fixed rod 13 drives the connecting rod 12 on the inner wall of the hinge seat 2 11 to rotate. This design makes the equipment more flexible and adaptable, meeting the needs of different scenarios. Finally, the connecting rod 12 pushes the clamping plate 2 14 to contact the outer wall of the instrument, further enhancing the stability of the instrument.

[0024] Reference Figure 1 and Figure 3 A screw rod 15 is fixedly connected to the lower surface of the mounting platform 1, and a plurality of sleeves 16 are fixedly connected to the adjacent side of the screw rod 15, and a positioning rod is fixedly connected between the plurality of sleeves 16; a rack column 17 is slidably connected to the inner wall of the sleeve 16, and a positioning nail 18 is rotatably connected to the lower surface of the rack column 17; a bolt 19 is rotatably connected to one side of the outer wall of the sleeve 16, a gear 20 is fixedly connected to the middle part of the outer wall of the bolt 19, the gear 20 is meshed and connected with the rack column 17, and a nut 21 is threadedly connected to the outer wall of the bolt 19; a sleeve 22 is slidably connected to the outer wall of the screw rod 15, and a threaded sleeve 23 is rotatably connected to the upper surface of the sleeve 22, and the threaded sleeve 23 is threadedly connected to the screw rod 15; the outer wall of the sleeve 22 is rotatably connected to a limiting plate 24, and the inner wall of the limiting plate 24 is rotatably connected to a support plate 25; the support plate 25 is rotatably connected to a stabilizing plate 26, and the support plate 25 is rotatably connected to the outer wall of the positioning rod;

[0025] Specifically, in the area that needs to be surveyed, the positioning pin 18 is inserted into the ground to ensure its stability. Next, by rotating the threaded sleeve 23, the threaded sleeve 23 drives the sleeve 22 to rise and fall. Under the action of the positioning pin 18 and the threaded sleeve 23, the limit plate 24 can smoothly push the support plate 25 to rotate. This process has a certain logical sequence, the purpose of which is to ensure the accuracy of the measurement data. The function of the support plate 25 is to support the stabilizing plate 26 so that it is in close contact with the ground to achieve the effect of stabilizing the device. When the height of the device needs to be adjusted, it can be achieved by turning the nut 21. First, loosen the nut 21, and then drive the gear 20 to engage with the rack column 17 by turning the bolt 19. In this way, the height of the device can be easily adjusted according to the use requirements. After the adjustment is completed, tighten the nut 21 to achieve the effect of limiting the rack column 17 by the stabilizing device.

[0026] Working principle: When it is necessary to survey the azimuth of topographic surveying, the positioning pin 18 is inserted into the area to be surveyed. At this time, the threaded sleeve 23 is rotated to drive the sleeve 22 to rise and fall, thereby driving the limit plate 24 to push the support plate 25 to rotate, and the support plate 25 drives the stabilizing plate 26 to contact the ground to stabilize the device. When the height of the device needs to be adjusted, the nut 21 is loosened by rotating it, and the bolt 19 is rotated to drive the gear 20 to engage with the rack column 17, so as to achieve the effect of facilitating the device to adjust the height according to the use requirements, and tightening the nut 21 to achieve the effect of stable limit.

[0027] Secondly, when the device is stable, the instrument is placed on the mounting table 1, and the rotating rod 3 is rotated to make the worm 4 mesh and rotate with the worm wheel 2, thereby achieving the effect of driving the multiple arc plates 6 on the outer wall of the turntable 5 to rotate, and the arc plates 6 drive the clamping plates 8 to clamp the instrument, thereby achieving the effect of stably installing the instrument. At this time, the electric push rod 1001 is started, and the fixed rod 13 on the inner wall of the hinge block 1002 is driven to move by the electric push rod 1001, and the connecting rod 12 on the inner wall of the hinge seat 2 11 is driven to rotate by the fixed rod 13, and the clamping plate 2 14 is pushed by the connecting rod 12 to contact the outer wall of the instrument, thereby achieving the effect of further stabilizing the instrument.
