Description

Technical Field

[0001] The present invention relates to the field of geographic surveying and mapping, and in particular to a total station for surveying and mapping geographic information based on national land space planning. Background Art

[0002] Total station is the abbreviation of total station electronic tachometer, which is a photoelectric instrument that combines electronic theodolite, photoelectric rangefinder and microprocessor.

[0003] After searching, the publication number CN111141266A discloses a gyroscopic total station, which includes a leveling mechanism and a total station body placed on top of the leveling mechanism. The leveling mechanism includes a first rotating shaft and a second rotating shaft, the axis of the second rotating shaft is perpendicular to the axis of the first rotating shaft, and the axis of the second rotating shaft is gear-engaged with the axis of the first rotating shaft. The leveling mechanism also includes a mounting platform and a rack, and the upper end of the rack is fixedly connected to the lower end of the mounting platform, and the lower end of the rack is meshed with the first rotating shaft. According to the present invention, the axis of the first rotating shaft is perpendicular to the center line of the rack. On the first rotating shaft, a first gear disk is provided at the connection position with the rack. The first gear disk is fixedly mounted on the first rotating shaft and meshes with the rack. A thread is provided on the outer side of the first rotating shaft, and a second gear disk is mounted on the second rotating shaft, and the second gear disk meshes with the thread of the first rotating shaft.

[0004] The gyroscopic total station disclosed above realizes the adjustment of the front and back and left and right dimensions of the total station by cooperating with the rack and the gear plate, but it still has the following defects: (1) During the rotation of the adjustment platform, there is a certain gap between the adjustment platform and the shell. The total station is usually used outdoors, and foreign matter such as dust, sand and gravel enter the gap between the adjustment platform and the shell, resulting in the subsequent adjustment of the horizontal position of the total station being limited. (2) It is necessary to adjust the horizontal degree of the loading platform in the left and right directions by rotating the first and second rotating shafts, which results in more than two operations to complete the horizontal adjustment of the total station. (3) After the leveling is completed, the positioning of the adjustment platform depends on the power control of the first electromagnet and the second electromagnet. It needs to go through multiple steps such as the adsorption of the first metal block, the movement of the second metal block, and the adsorption of the second electromagnet. Not only is the operation complicated, but there is also the risk of positioning failure due to power failure or failure of the electromagnet. As a result, the above-mentioned gyroscopic total station will face many problems in actual geographic surveying and mapping work, which seriously affects the measurement efficiency and data quality.

[0005] Therefore, it is necessary to provide a surveying and mapping geographic information total station based on national land space planning to solve the above problems. Summary of the Invention

[0006] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a surveying and mapping geographic information total station based on national land space planning.

[0007] To achieve the above objectives, the present invention provides the following technical solutions: a total station for surveying and mapping geographic information based on national land space planning, comprising a telescopic tripod, a total station main unit, a controller, a level tube, and a laser, wherein the total station main unit is arranged above the telescopic tripod, the controller and the level tube are mounted on the total station main unit, the laser is arranged on the top of the telescopic tripod, and the top of the telescopic tripod is provided with a limiting component; The limiting assembly includes a groove block, which is fixedly connected to the top of the telescopic tripod. The bottom of the inner cavity of the groove block is annularly distributed and fixedly connected with an elastic limiting piece. The top of the inner cavity of the groove block is slidably connected with an annular extrusion block, and the top of the annular extrusion block is fixedly connected with an annular limiting plate.

[0008] Preferably, the limiting assembly further includes a connecting rod, which is arranged below the total station mainframe, a spherical adjustment block is fixedly connected to the bottom of the connecting rod, and an elastic dust cover is slidably connected to the outer wall of the connecting rod.

[0009] Preferably, the limiting assembly further includes four electric telescopic rods, which are distributed in a ring shape and fixedly installed inside the groove block, and the output shaft of each electric telescopic rod is fixedly connected to the annular limiting plate.

[0010] Preferably, a fixing assembly is provided on the top of the telescopic tripod, and the fixing assembly includes a right-angle positioning frame. The right-angle positioning frame is detachably mounted on the top of the telescopic tripod, and the top of the right-angle positioning frame is rotatably connected to three F-shaped limit clamps distributed in a triangular shape.

[0011] Preferably, the fixing assembly also includes a fixing plate, which is rotatably connected to the bottom of the total station host. The outer wall of the fixing plate is triangularly distributed and fixedly connected with three rectangular limit blocks, and each of the F-shaped limit clips is respectively engaged with each rectangular limit block.

[0012] Preferably, an outer wall of the fixing plate is provided with an adjustment component, the adjustment component includes an adjustment rod group, the outer wall of the adjustment rod group is provided with an electric control button, and the outer wall of the electric control button is rotatably connected to an anti-mistouch shell.

[0013] Preferably, the electric control button is used to control the start of the electric telescopic rod.

[0014] Preferably, the laser is fixedly mounted on the bottom of the spherical adjusting block, the top of the annular extrusion block is arranged to be inclined, and the bottom of the elastic limiting piece is arranged to be inclined.

[0015] Preferably, the connecting rod is fixedly connected to the bottom of the fixing plate, and the elastic dust cover is sleeved on the outer side of the groove block.

[0016] Preferably, the groove block is connected to the top of the right-angle positioning frame, the spherical adjustment block is rotatably connected to the inside of the groove block, and the laser is located inside the groove block and the right-angle positioning frame.

[0017] The present invention provides a total station for surveying and mapping geographic information based on national land space planning. Compared with the prior art, the present invention has the following beneficial effects: By controlling the rise of the electric telescopic rod with one click of the electric control button, the lock of the elastic limit piece on the spherical adjustment block can be released. At this time, the spherical adjustment block can be freely rotated in multiple directions in the groove block. When the staff holds the adjustment rod group for fine-tuning, the horizontal position centering of the total station host and the centering of the bubble in the spirit level can be completed simultaneously through the flexible rotation of the spherical adjustment block. There is no need to adjust in steps in multiple dimensions such as front and back, left and right. One fine-tuning operation can meet the dual requirements of level and centering, reducing the number of adjustments and improving operating efficiency.

[0018] After the total station completes fine centering and leveling, you only need to press the electric control button again to drive the annular extrusion block down through the electric telescopic rod. The annular extrusion block is used to contact the inclined surface of the elastic limit piece, so that the elastic limit piece covers the spherical adjustment block. The spherical adjustment block is firmly locked through a purely mechanical structure. At the same time, the anti-accidental touch shell design can wrap the electric control button during surveying and mapping work to prevent the staff from accidentally touching it and causing unexpected movement of the electric telescopic rod, thereby ensuring the continuity and stability of the measurement process.

[0019] This positioning method does not rely on electrical components such as electromagnets. The operation steps are simplified to one-button control, and the mechanical locking structure is more stable. It can effectively avoid horizontal deviation caused by electrical failures and ensure that the position of the total station host is always accurate and stable during the measurement process.

[0020] By setting up the elastic dust cover, the contact area between the groove block and the spherical adjustment block can be tightly wrapped, blocking foreign matter from entering at the source, ensuring that the spherical adjustment block always maintains a flexible rotation state in the groove block, avoiding the problem of restricted adjustment caused by foreign matter getting stuck, and significantly improving the long-term stable operation capability of the equipment in complex outdoor environments.

[0021] In the equipment fixing and releasing process, the clip-on design of the F-shaped limit clamp and the rectangular limit block realizes the rapid fixing and convenient unlocking of the total station host. The staff only needs to rotate the F-shaped limit clamp away from the rectangular limit block to release the restriction on the fixed plate. The operation steps are intuitive and easy to understand. This structure not only ensures the stability of the equipment during transportation or initial fixing, but also can quickly release the restriction when fine-tuning is required, reducing the tedious disassembly and installation steps in traditional mechanical fixing methods.

[0026] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0027] Implementation example Figure 1 、 Figure 2 、 Figures 9 to 12 As shown, a total station for surveying and mapping geographic information based on land space planning provided by one embodiment of the present invention includes a telescopic tripod 11, a total station main unit 12, a controller 13, a level tube 14, and a laser 15. The total station main unit 12 is arranged above the telescopic tripod 11, the controller 13 and the level tube 14 are installed on the total station main unit 12, the laser 15 is arranged on the top of the telescopic tripod 11, and a limiting component is provided on the top of the telescopic tripod 11. Specifically: the total station host 12 integrates an electronic theodolite, a photoelectric rangefinder and a microprocessor, and is responsible for accurately measuring horizontal angles, vertical angles and distances, while processing measurement data to realize core functions such as three-dimensional coordinate measurement and layout; the level tube 14 is a horizontal calibration tool, which determines whether the total station host 12 is horizontal by whether the bubble in the tube is centered, ensuring the benchmark accuracy of angle and distance measurement, and is the basic guarantee for high-precision surveying and mapping; the laser 15 is used to assist in the centering positioning device, emitting a laser beam to form a light spot on the ground, quickly aligning to the center point of the ground, and improving the centering efficiency and accuracy when the light is poor or the visibility is poor. The above are all existing technologies and will not be elaborated here.

[0028] The limiting component includes a groove block 34, which is fixedly connected to the top of the telescopic tripod 11. The bottom of the inner cavity of the groove block 34 is annularly distributed and fixedly connected to an elastic limit piece 38. The top of the inner cavity of the groove block 34 is slidably connected to an annular extrusion block 37, and the top of the annular extrusion block 37 is fixedly connected to an annular limiting plate 36.

[0029] The limiting assembly also includes a connecting rod 31 , which is arranged below the total station mainframe 12 . A spherical adjustment block 32 is fixedly connected to the bottom of the connecting rod 31 , and an elastic dust cover 33 is slidably connected to the outer wall of the connecting rod 31 .

[0030] The limiting assembly further includes four electric telescopic rods 35 , which are distributed in an annular shape and fixedly installed inside the groove block 34 , and the output shaft of each electric telescopic rod 35 is fixedly connected to the annular limiting plate 36 .

[0031] Specifically, the laser 15 is fixedly mounted on the bottom of the spherical adjustment block 32, the top of the annular extrusion block 37 is set to be inclined, and the bottom of the elastic limit piece 38 is set to be inclined, so that when the annular extrusion block 37 descends, the elastic limit piece 38 can cover the spherical adjustment block 32 for limitation, and the elastic dust cover 33 is sleeved on the outside of the groove block 34 to prevent foreign matter from mixing into the interior of the groove block 34. The groove block 34 is connected to the top of the right-angle positioning frame 21, and the spherical adjustment block 32 is rotatably connected to the inside of the groove block 34. The laser 15 is located inside the groove block 34 and the right-angle positioning frame 21.

[0032] like Figures 3 to 6 As shown, a fixing assembly is provided on the top of the telescopic tripod 11, and the fixing assembly includes a right-angle positioning frame 21. The right-angle positioning frame 21 is detachably mounted on the top of the telescopic tripod 11, and the top of the right-angle positioning frame 21 is rotatably connected to three F-shaped limit clamps 22 distributed in a triangular shape.

[0033] The fixing assembly also includes a fixing plate 23, which is rotatably connected to the bottom of the total station host 12. The outer wall of the fixing plate 23 is triangularly distributed and fixedly connected with three rectangular limit blocks 24, and each F-shaped limit clip 22 is respectively engaged with each rectangular limit block 24.

[0034] Specifically, the connecting rod 31 is fixedly connected to the bottom of the fixing plate 23 , and the movement of the fixing plate 23 is restricted by restricting the spherical adjustment block 32 at the bottom of the connecting rod 31 .

[0035] like Figure 7 and Figure 8 As shown, the outer wall of the fixing plate 23 is provided with an adjustment component, which includes an adjustment rod group 41. The outer wall of the adjustment rod group 41 is provided with an electric control button 42. The outer wall of the electric control button 42 is rotatably connected to an anti-mistouch shell 43.

[0036] Specifically, the electric control button 42 is used to control the start of the electric telescopic rod 35 , and the electric telescopic rod 35 controls the elastic limiting piece 38 and the annular limiting plate 36 to contact the spherical adjustment block 32 for limiting.

[0037] In combination with the above embodiments, the entire working process and working principle of the above embodiments are as follows: Working principle: Initial alignment: When workers use a total station for geographic surveying, they first need to roughly align the center point. Before setting up the telescopic tripod 11, they need to use the optical plummet on the tripod to roughly align the ground center point. At this time, there is no need for precise centering, but the tripod head should be kept level and the top surface of the tripod should be roughly aligned with the ground point. Then step firmly on the 11 legs of the telescopic tripod to ensure that the tripod is initially stable. If the ground is uneven, you can adjust the length of the tripod to make the tripod head roughly level.

[0038] After completing the above operations, enter the fine alignment and leveling stage: Before the total station main unit 12 is fixed to the telescopic tripod 11, the optical plummet on the telescopic tripod 11 is roughly aligned with the center point of the ground. At this time, the total station main unit 12 is fixed to the top of the telescopic tripod 11. Then, the staff rotates the F-shaped limit clamp 22 in the direction away from the rectangular limit block 24, so that the F-shaped limit clamp 22 rotates around the right-angle positioning frame 21; When the F-shaped limiting clip 22 is disengaged from the rectangular limiting block 24 , the restriction on the movement of the fixing plate 23 is released, making it easier to fine-tune the total station mainframe 12 on top of the fixing plate 23 .

[0039] Fine alignment and leveling: After the above work is completed, the total station main unit 12 is fixed to the telescopic tripod 11. The staff needs to accurately align the laser 15 with the center point of the ground. At this time, the staff holds the adjustment rod group 41 with both hands and then presses the electric control button 42 on the adjustment rod group 41. The electric control button 42 is used to control the activation of the electric telescopic rods 35, and then the electric control button 42 first controls the four electric telescopic rods 35 to rise; When the four electric telescopic rods 35 drive the annular limiting plate 36 at the top to rise, the annular limiting plate 36 will drive the annular extrusion block 37 at the bottom to rise synchronously. Then the annular extrusion block 37 gradually rises above the elastic limiting piece 38, and then the annular extrusion block 37 stops resisting the elastic limiting piece 38, and the elastic limiting piece 38 resumes its elastic extension state, releasing the interference limit on the spherical adjustment block 32, and then the elastic limiting piece 38 can no longer restrict the spherical adjustment block 32; At this time, the staff observes the ground control point through the eyepiece on the total station host 12 or the laser pointer of the laser 15, and then fine-tunes the horizontal position of the total station host 12. The position of the total station host 12 can be adjusted by holding the adjustment rod group 41 on both sides of the fixed plate 23, so that the fixed plate 23 drives the spherical adjustment block 32 to rotate inside the groove block 34 through the connecting rod 31 at the bottom. The spherical adjustment block 32 is used to align the ray emitted by the laser 15 with the center point of the ground. At the same time, it is necessary to center the bubble inside the level tube 14 to ensure that the total station host 12 is level. Until the ray is aligned with the center point of the ground and the bubble inside the level tube 14 is centered, both requirements are met, and the horizontal adjustment of the total station host 12 is completed. After the ray emitted by the laser 15 is aligned with the center point of the ground, the staff presses the electric control button 42 again, so that the electric telescopic rod 35 will drive the top annular limiting plate 36 to descend, so that the annular limiting plate 36 drives the bottom annular extrusion block 37 to descend synchronously, and then the annular extrusion block 37 gradually contacts the elastic limiting piece 38, and the top of the annular extrusion block 37 is set to an inclined shape, and the bottom of the elastic limiting piece 38 is set to an inclined shape, and then the inclined surface of the annular extrusion block 37 contacts the inclined surface of the elastic limiting piece 38, and then the elastic limiting piece 38 covers the spherical adjustment block 32, and then the elastic limiting piece 38 is subjected to the force of the annular extrusion block 37 and contacts the spherical adjustment block 32, and finally the position of the spherical adjustment block 32 is fixed, and at the same time, the spherical adjustment block 32 fixes the position of the total station host 12 after fine-tuning through the top connecting rod 31 and the fixing plate 23; By pressing the electric control button 42 to raise the electric telescopic rod 35, the elastic limit plate 38 can be released from the lock on the spherical adjustment block 32. At this time, the spherical adjustment block 32 can freely rotate in multiple directions within the groove block 34, and the connecting rod 31 will slide along the inner side of the annular limit plate 36. At the same time, the laser 15 at the bottom of the spherical adjustment block 32 rotates along the inner side of the right-angle positioning frame 21. When the staff holds the adjustment rod group 41 for fine-tuning, the horizontal position centering of the total station host 12 and the centering of the bubble in the spirit level 14 can be completed simultaneously through the flexible rotation of the spherical adjustment block 32. There is no need to adjust in steps in multiple dimensions such as front and back, left and right. One fine-tuning operation can meet the dual requirements of level and centering, reducing the number of adjustments and improving operating efficiency.

[0040] After the total station completes fine centering and leveling, it is only necessary to press the electric control button 42 again to drive the annular extrusion block 37 to descend through the electric telescopic rod 35. The annular extrusion block 37 is then brought into contact with the inclined surface of the elastic limiting piece 38, so that the elastic limiting piece 38 covers the spherical adjustment block 32, thereby achieving a secure locking of the spherical adjustment block 32 through a purely mechanical structure.

[0041] The elastic dust cover 33 on the outer wall of the connecting rod 31 can tightly wrap the contact area between the groove block 34 and the spherical adjustment block 32, blocking foreign matter from entering from the source, ensuring that the spherical adjustment block 32 always maintains a flexible rotation state in the groove block 34, avoiding the problem of adjustment restriction caused by foreign matter getting stuck, and significantly improving the long-term stable operation capability of the equipment in complex outdoor environments.

[0042] Then the staff rotates the anti-accidental-touch shell 43 toward the electric control button 42 so that the anti-accidental-touch shell 43 wraps the electric control button 42, thereby preventing the staff from accidentally touching the electric control button 42 when performing geographic surveying and mapping work through the total station host 12, thereby ensuring the continuity and stability of the measurement process.

[0043] Finally, after the total station host 12 completes the surveying and mapping of geographic information, the same movement process as above is used to make the connecting rod 31 and the spherical adjustment block 32 and the groove block 34 vertical. The staff rotates the F-shaped limit clamps 22 in turn, so that the three F-shaped limit clamps 22 are clamped to the rectangular limit block 24 on the outer wall of the fixed plate 23 in turn, and the F-shaped limit clamps 22 and the rectangular limit block 24 are both arranged in a triangular shape, thereby ensuring the stability of fixing the fixed plate 23 and the total station host 12. The stable fixation of the fixed plate 23 and the total station host 12 is ensured by three-point positioning, avoiding shaking and collision of the equipment during transportation or storage, and playing a good protective role.

[0044] This positioning method does not rely on electrical components such as electromagnets, and the operation steps are simplified to one-button control. The mechanical locking structure is more stable and can effectively avoid horizontal deviation caused by electrical failures, ensuring that the position of the total station host 12 is always accurate and stable during the measurement process. In the equipment fixing and releasing restriction link, the snap-on design of the F-shaped limit clamp 22 and the rectangular limit block 24 realizes the rapid fixing and convenient unlocking of the total station host 12. The staff only needs to rotate the F-shaped limit clamp 22 away from the rectangular limit block 24 to release the restriction on the fixing plate 23. The operation steps are intuitive and easy to understand. This structure not only ensures the stability of the equipment during transportation or initial fixation, but also can quickly release the restriction when fine-tuning is required, reducing the cumbersome disassembly and installation steps in traditional mechanical fixing methods.
