Description

Technical Field

[0001] This utility model relates to the field of surveying and mapping equipment technology, and in particular to a positioning device for land surveying. Background Technology

[0002] Land surveying is an important technical activity that uses modern technology to measure and depict ground features and boundaries. It involves using computer technology, optoelectronic technology, network communication technology, space science, and information science as its foundation, and global positioning system, remote sensing, and geographic information system as its core technologies to obtain graphic and location information reflecting the current state of the ground from existing features and boundaries through measurement methods. This information is then used for planning and design of engineering construction and for administrative management. Land surveying often uses surveying instruments, which are usually equipped with tripods. The purpose of the tripod is to support and stabilize the surveying instrument on the tripod.

[0003] A search revealed that Chinese Patent CN213956396U discloses a positioning device for a land surveying instrument. This device addresses the limitation of existing positioning devices that cannot easily adjust the surveying height of the instrument, thus enabling convenient adjustment of the surveying height.

[0004] The aforementioned positioning device facilitates the adjustment of the surveying height. However, in existing technologies, a tripod is typically used for support when using a surveying instrument. When using a tripod, the balance of the three legs needs to be adjusted to ensure that the tripod is stably placed on the ground through mutual restraint. During the adjustment and use of the tripod, it is easy for it to collapse due to unintentional human contact or insufficient stability when placed. This can cause the surveying instrument on the tripod to tip over, resulting in damage to the surveying instrument, increased maintenance costs, and a significant impact on surveying efficiency. Utility Model Content

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a positioning device for land surveying, comprising a tripod, a stabilizing plate disposed below the tripod, and a stabilizing component disposed on the upper surface of the stabilizing plate;

[0007] The stabilizing component includes multiple mounting rods, which are fixedly connected to the upper surface of the stabilizing plate. One end of each mounting rod has a threaded groove, and a limit sleeve is threadedly connected to the outside of the threaded groove. A sliding sleeve is slidably connected to the outside of the mounting rod. A first threaded hole is formed on one side of the sliding sleeve, and a bolt is threadedly connected to the inside of the first threaded hole. Multiple second threaded holes are formed on the upper surface of the stabilizing plate.

[0008] As a further description of the above technical solution:

[0009] The second threaded hole has an internal threaded connection to a screw rod, one end of which is fixedly connected to a throttle handle, and the other end of which is fixedly connected to a first ground nail post.

[0010] As a further description of the above technical solution:

[0011] A connecting rod is fixedly connected to one side of the first ground nail post, and a second ground nail post is fixedly connected to one end of the connecting rod. Rotating rods are respectively hinged to both sides of the first ground nail post.

[0012] As a further description of the above technical solution:

[0013] One end of the rotating rod is hinged to a slider, and the lower surface of the stabilizing plate is provided with multiple grooves, with the slider slidably connected inside the grooves.

[0014] As a further description of the above technical solution:

[0015] A movable component is provided on the outside of the stabilizing plate. The movable component includes multiple mounting blocks, which are fixedly connected to the outside of the stabilizing plate.

[0016] As a further description of the above technical solution:

[0017] The mounting block has multiple limiting holes on one side, a sliding frame is slidably connected to the outside of the mounting block, a universal wheel is fixedly installed on the lower surface of the sliding frame, and a mounting box is fixedly connected to the upper surface of the sliding frame.

[0018] As a further description of the above technical solution:

[0019] An E-shaped frame is slidably connected to one side of the mounting box, a connecting plate is fixedly connected to the middle of the E-shaped frame, and multiple springs are fixedly connected to one side of the connecting plate. One end of each spring is fixedly connected to the inner wall of the mounting box.

[0020] This utility model has the following beneficial effects:

[0021] This invention, through the design of a stabilizing component, increases the stability of the tripod during surveying by utilizing the larger stable surface of the stabilizing plate. Furthermore, the insertion of the first and second ground anchors into the soil enhances the stability of the stabilizing plate during installation. Simultaneously, the screw allows for easy adjustment of the downward movement distance of the first and second ground anchors, facilitating adaptation to varying ground elevations and improving the stability of the stabilizing plate. This reduces the risk of tripod collapse and damage to the surveying instrument, contributing to overall stability during the surveying process. Additionally, the threaded groove and limiting sleeve facilitate the separation of the tripod and stabilizing component, making this invention easy to carry.

[0022] This invention, through the design of a movable component, facilitates the movement of the tripod and stabilizing components to different spatial locations when the surveying site needs to be changed. It allows the tripod to be moved along with the surveyors, reducing the difficulty and effort required for manual handling and helping to improve surveying efficiency. Attached Figure Description

[0035] As attached Figure 5 As shown, a screw 10 is threadedly connected to the inside of the second threaded hole 9. A throttle 11 is fixedly connected to one end of the screw 10, and a first ground nail post 12 is fixedly connected to the other end of the screw 10. A connecting rod 13 is fixedly connected to one side of the first ground nail post 12, and a second ground nail post 14 is fixedly connected to one end of the connecting rod 13. Rotating rods 15 are hinged to both sides of the first ground nail post 12, and a slider 16 is hinged to one end of the rotating rod 15. The screw 10 facilitates the movement of the height position of the first ground nail post 12. The second ground nail post 14 helps to improve the stability of the placement of the stabilizing plate 2 in cooperation with the first ground nail post 12. The slider 16 slides inside the groove 17, which facilitates the limiting of the movement of the first ground nail post 12.

[0036] As attached Figure 4As shown, the lower surface of the stabilizing plate 2 is provided with multiple grooves 17, and the slider 16 is slidably connected inside the groove 17. The cross-section of the groove 17 is convex.

[0037] As attached Figure 6 As shown, a movable component is provided on the outside of the stabilizing plate 2. The movable component includes multiple mounting blocks 18, which are fixedly connected to the outside of the stabilizing plate 2. Multiple limiting holes 19 are provided on one side of the mounting block 18, which are used for flexible engagement of the E-type frame 23.

[0038] As attached Figure 7 As shown, a sliding frame 20 is slidably connected to the outside of the mounting block 18. A caster wheel 21 is fixedly installed on the lower surface of the sliding frame 20. A mounting box 22 is fixedly connected to the upper surface of the sliding frame 20. An E-shaped frame 23 is slidably connected to one side of the mounting box 22. A connecting plate 24 is fixedly connected to the middle of the E-shaped frame 23. Multiple springs 25 are fixedly connected to one side of the connecting plate 24. One end of the multiple springs 25 is fixedly connected to the inner wall of the mounting box 22. The sliding frame 20 facilitates the adjustment of the height by driving the caster wheel 21. One side of the E-shaped frame 23 facilitates engagement with the limiting hole 19. With the connection of the connecting plate 24, the springs 25 facilitate the elastic pushing effect on the E-shaped frame 23.

[0039] Working principle: When installing this utility model, firstly, the limiting sleeve 5 at one end of the mounting rod 3 is unscrewed from one end of the mounting rod 3 under the action of the threaded groove 4. Then, the three legs of the tripod 1 are in an adjustable length state, and the sliding sleeve 6 at one end is slidably fitted onto the outside of the mounting rod 3. Then, the limiting sleeve 5 is screwed back onto the outside of the threaded groove 4. Then, the sliding sleeve 6, after being positioned, is fixed by turning the bolt 8 under the connection of the first threaded hole 7. Then, the length of the three legs of the tripod 1 is adjusted. Finally, the stabilizing plate 2 is placed on the muddy ground that needs to be surveyed. According to the unevenness of the ground, turn the corresponding handle 11, which drives the screw 10 to rotate inside the second threaded hole 9, so that the first ground nail post 12 and the second ground nail post 14 connected to the connecting rod 13 move down together. At the same time, the first ground nail post 12 drives the rotating rods 15 on both sides to rotate, and drives the slider 16 to slide inside the slide groove 17 to limit the first ground nail post 12. When the first ground nail post 12 and the second ground nail post 14 on the adjustment side move down to a suitable distance and the ground nail post is inserted into the muddy ground, so that the stabilizing plate 2 is in a parallel state, the adjustment is completed.

[0040] When it is necessary to move this utility model, first lift the tripod 1 to move the utility model to the cement road surface, then pull the E-shaped frame 23 so that one end of it disengages from the corresponding limiting hole 19. At this time, the sliding frame 20 is in an adjustable state. Then, slide the sliding frame 20 downward outside the mounting block 18 so that the sliding frame 20 drives the universal wheel 21 to move down to the horizontal plane above the tip of the first ground nail post 12. Then, release the E-shaped frame 23. When the multiple springs 25 are pushed back, under the elastic force of the pushing connecting plate 24, one side of the E-shaped frame 23 is driven into the interior of the corresponding multiple limiting holes 19, thereby fixing the position of the sliding frame 20 and the universal wheel 21. Then it is convenient to pull the tripod 1 to move this utility model.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
