Description

Technical Field

[0001] This invention relates to the field of surveying instrument technology, specifically to a field surveying device based on BIM technology. Background Technology

[0002] BIM technology is a data-driven tool applied to engineering design, construction, and management. It features visualization, coordination, simulation, optimization, and drawing generation capabilities. Through the integration of digitized and information-based building models, it facilitates sharing and transmission throughout the entire project lifecycle, from planning and operation to maintenance. This enables engineering professionals to accurately understand and efficiently respond to various building information, providing a foundation for collaborative work among all construction stakeholders. It plays a crucial role in improving productivity, saving costs, and shortening construction periods. The application of BIM technology requires the use of surveying equipment such as mapping instruments to collect relevant information and data about building facilities. Therefore, a user-friendly and efficient surveying system is highly beneficial to the progress of construction.

[0003] In existing surveying technology, surveying devices are generally mounted on tripods. In actual use, the surveying instrument is first fixed to the top of the tripod, and then the tripod is extended and placed at the surveying point. However, in actual surveying, we have found that harsh surveying environments can have a significant impact on surveying accuracy. For example, if the ground is soft or uneven, the tripod will be unstable, thus affecting the surveying accuracy. To solve this problem, some tripods on the market have ground stakes. The entire device is stabilized by inserting the ground stakes into the ground. However, after use, the ground stakes often have a lot of dirt stuck to them. If they are not cleaned in time, they are not only inconvenient to carry, but they will also dirty the storage tools (such as the trunk of a vehicle). At the same time, the ground stakes at the bottom of traditional tripods are not easy to retract, which poses certain safety hazards when carrying them.

[0004] Based on this, we propose a field surveying device based on BIM technology. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a field surveying device based on BIM technology, which has the advantages of retractable ground stakes and easy cleaning of soil on the ground stakes.

[0011] The bottom of the support rod has an inner cavity, in which ground nails are movably and retractably installed. A cleaning mechanism is also installed at the bottom of the support rod. When the ground nails retract from the outside of the inner cavity into the inner cavity, the cleaning mechanism can clean the surface of the ground nails.

[0012] As a preferred technical solution of the present invention, the cleaning mechanism includes an annular base plate, movable blocks, elastic ropes and elastic rubber strips. The bottom of the support rod is fixedly installed with an annular base plate. A plurality of movable blocks are uniformly arranged in a ring inside the annular base plate, and the plurality of movable blocks are slidably arranged on the inner bottom wall of the annular base plate.

[0013] Each of the several movable blocks has a rope groove on its outward-facing side, and an elastic rope is wrapped around the several rope grooves;

[0014] Each of the movable blocks has an inward-facing slope, and an elastic rubber strip is fixedly installed at the bottom of the slope.

[0015] As a preferred embodiment of the present invention, a limiting block is also fixedly installed on the inner bottom wall of the annular base plate. The limiting block is movably disposed in a limiting groove, which is located at the bottom of the movable block.

[0016] As a preferred embodiment of the present invention, a vertical rod is fixedly installed on the top of the ground nail, the vertical rod is inserted into the fixing plate, and the fixing plate is fixedly installed in the inner cavity;

[0017] A pressure plate is also fixedly installed on the outer wall of the vertical rod, and a spring is provided between the pressure plate and the fixed plate, with the spring sleeved on the vertical rod.

[0018] As a preferred embodiment of the present invention, L-shaped rods are fixedly installed on both sides of the top of the vertical rod, and the bottom end of the L-shaped rod is rotatably connected to the foot ring;

[0019] A sliding block is fixedly installed on the inner peripheral wall of the foot ring. The sliding block is slidably disposed in a vertical groove, which is opened on the outer wall of the support rod.

[0020] The sidewall of the vertical slide groove is also evenly provided with several side positioning grooves for the sliding block to enter.

[0021] As a preferred embodiment of the present invention, the outer wall of the support rod is further provided with a movable groove for moving the L-shaped rod.

[0022] As a preferred embodiment of the present invention, the top end of the support rod is provided with a rod groove, and an insert rod is movably and telescopically arranged in the rod groove;

[0023] A top block is fixedly installed between the two fixed seats, and a number of locking grooves coupled to the insertion rod are evenly opened on the inner arc surface of the bottom of the top block.

[0024] As a preferred embodiment of the present invention, the top end of the vertical rod is connected to the active toothed plate via an elastic band, a transmission wheel is engaged on the outer wall of the active toothed plate, a driven toothed plate is engaged on the other side of the transmission wheel, and the insertion rod is fixedly installed on the top end of the driven toothed plate.

[0025] Both the active toothed plate and the driven toothed plate are slidably disposed in the inner groove, which is opened inside the support rod.

[0026] The drive wheel is rotatably mounted in the inner groove.

[0027] (III) Beneficial Effects

[0028] Compared with existing technologies, the present invention provides a field surveying device based on BIM technology, which has the following beneficial effects:

[0029] 1. This BIM-based field surveying device can effectively position the support rod by extending the ground spikes from inside the support rod, preventing the support rod from shaking during the surveying process; by retracting the ground spikes into the support rod, the ground spikes can be effectively stored, making them easy to carry, store, and transport, and at the same time, the sharpness of the ground spikes will not cause injury to the staff.

[0030] 2. This BIM-based field surveying device, when the ground nail extends from the inner cavity, pushes several moving blocks apart through its conical surface, causing the moving blocks to move away from each other and stretching the elastic rope and elastic rubber strip. When the ground nail retracts into the inner cavity, the moving blocks move closer together under the action of the elastic rope, thus keeping the elastic rubber strip in close contact with the conical surface of the ground nail and scraping off the dirt on the ground nail, thereby achieving the effect of automatically cleaning the ground nail and keeping the ground nail clean.

[0031] 3. This BIM-based field surveying device features a foot pedal ring that allows the vertical rod to move downwards via an L-shaped rod. As the vertical rod moves downwards, it compresses the spring through the pressure plate, causing the ground nail to move downwards and protrude from the inner cavity. This makes it simpler and more convenient to use, with a low learning curve. Attached Figure Description

[0040] Example 1:

[0041] Please see Figures 1-4 A field surveying device based on BIM technology includes a mounting platform 1, and a surveying instrument 2 is mounted on the top of the mounting platform 1. The surveying instrument 2 can be installed in any of the existing technologies, and is not limited in this embodiment.

[0042] like Figure 1 and Figure 2 As shown, a support rod 4 is also provided. The top end of the support rod 4 is rotatably set between two fixed seats 3 via a rotating shaft 5. Both fixed seats 3 are fixedly installed at the bottom of the mounting platform 1. As shown in the figure, in this embodiment, there are three support rods 4 in total, forming a triangular bracket.

[0043] like Figure 3 As shown, an inner cavity 6 is provided at the bottom of the support rod 4. A ground nail 7 is movably and retractably installed in the inner cavity 6. By extending the ground nail 7 from the support rod 4 (inserting into the ground surface), the support rod 4 can be effectively positioned to prevent it from shaking during the surveying process. By retracting the ground nail 7 into the support rod 4, the ground nail 7 can be effectively stored, making it easy to carry, store, and transport. At the same time, the sharpness of the ground nail 7 will not cause injury to the staff.

[0044] like Figure 3 and Figure 4 As shown, a cleaning mechanism is also installed at the bottom of the support rod 4. When the ground nail 7 retracts from the outside of the inner cavity 6 into the inner cavity 6, the cleaning mechanism can clean the surface of the ground nail 7. In this embodiment, the cleaning mechanism specifically includes an annular base plate 8, a moving block 9, an elastic rope 11 and an elastic rubber strip 12. An annular base plate 8 is fixedly installed at the bottom of the support rod 4. Several moving blocks 9 are evenly arranged in a ring inside the annular base plate 8. Several moving blocks 9 are slidably arranged on the inner bottom wall of the annular base plate 8.

[0045] Several movable blocks 9 have rope grooves 10 on their outward-facing sides, and elastic ropes 11 are wrapped around the rope grooves 10. Several movable blocks 9 have sloping surfaces on their inward-facing sides, and elastic rubber strips 12 are fixedly installed at the bottom of the sloping surfaces.

[0046] When the ground nail 7 extends out of the inner cavity 6, it pushes several moving blocks 9 apart through its conical surface, causing the moving blocks 9 to move away from each other and stretching the elastic rope 11 and the elastic rubber strip 12. When the ground nail 7 retracts into the inner cavity 6, the moving blocks 9 move closer to each other under the action of the elastic rope 11, so that the elastic rubber strip 12 always sticks tightly to the conical surface of the ground nail 7 and scrapes off the dirt on the ground nail 7, thereby achieving the effect of automatically cleaning the ground nail 7 and keeping the ground nail 7 clean.

[0047] In this embodiment, a limiting block 13 is also fixedly installed on the inner bottom wall of the annular base plate 8. The limiting block 13 is movably disposed in the limiting groove 14, which is located at the bottom of the movable block 9.

[0048] By sliding the limiting block 13 within the limiting groove 14, the movement range of the moving block 9 can be limited, and its movement can be made more stable.

[0049] Example 2:

[0050] Please see Figure 5 and Figure 6 Based on the first embodiment, in this embodiment, a vertical rod 15 is fixedly installed on the top of the ground nail 7. The vertical rod 15 is inserted into the fixing plate 17. The fixing plate 17 is fixedly installed in the inner cavity 6. A pressure plate 16 is also fixedly installed on the outer wall of the vertical rod 15. A spring 18 is provided between the pressure plate 16 and the fixing plate 17. The spring 18 is sleeved on the vertical rod 15.

[0051] In addition, L-shaped rods 19 are fixedly installed on both sides of the top of the vertical rod 15. The bottom end of the L-shaped rod 19 is rotatably connected to the foot ring 20. The outer wall of the support rod 4 is provided with a movable groove for moving the L-shaped rod 19.

[0052] The foot pedal ring 20 can move the vertical rod 15 down via the L-shaped rod 19. As the vertical rod 15 moves down, it compresses the spring 18 via the pressure plate 16, which in turn moves the ground nail 7 down, allowing it to protrude from the inner cavity 6. This makes it simpler and more convenient to use, with a low learning curve.

[0053] like Figure 6 As shown, a sliding block 21 is fixedly installed on the inner peripheral wall of the foot ring 20. The sliding block 21 is slidably disposed in the vertical slide groove 22. The vertical slide groove 22 is opened on the outer wall of the support rod 4. Several side positioning grooves 23 are also evenly opened on the side wall of the vertical slide groove 22 for the sliding block 21 to enter.

[0054] The foot pedal ring 20 can move the vertical rod 15 downwards via the L-shaped rod 19. When the foot pedal ring 20 moves downwards, the sliding block 21 also slides within the vertical groove 22. When it is necessary to lock the position of the foot pedal ring 20, force is applied to the foot to make the foot pedal ring 20 rotate, thereby causing the sliding block 21 to engage in the side positioning groove 23, thus locking the position of the foot pedal ring 20, and consequently locking the positions of the L-shaped rod 19, the vertical rod 15, and the ground stake 7.

[0055] Example 3:

[0056] Please see Figure 7 Based on Embodiment 1 or Embodiment 2, in this embodiment, the top end of the support rod 4 is provided with a rod groove 30, and an insert rod 29 is movably and telescopically arranged in the rod groove 30. In addition, a top block 31 is fixedly installed between the two fixed seats 3, such as... Figure 7 As shown, several locking grooves 32 that are coupled to the insertion rod 29 are evenly provided on the inner arc surface at the bottom of the top block 31.

[0057] The support rod 4 can be rotated and adjusted via the rotating shaft 5. After being adjusted to a suitable position, the control rod 29 extends and its top end is locked into the locking groove 32, which can lock the position of the support rod 4 and effectively prevent the support rod 4 from rotating again.

[0058] In this embodiment, the top end of the vertical rod 15 is connected to the active toothed plate 25 via an elastic band 24. The outer wall of the active toothed plate 25 is engaged with a transmission wheel 26, and the other side of the transmission wheel 26 is engaged with a driven toothed plate 27. The insertion rod 29 is fixedly installed on the top end of the driven toothed plate 27.

[0059] Both the active toothed plate 25 and the driven toothed plate 27 are slidably disposed in the inner groove 28, which is opened inside the support rod 4, and the transmission wheel 26 is also rotatably disposed in the inner groove 28;

[0060] In addition, a tension spring (not shown in the figure) is provided between the top of the active toothed plate 25 and the inner top wall of the inner groove 28. When the active toothed plate 25 moves down, the tension spring will be stretched.

[0061] Therefore, when the vertical rod 15 moves down and the ground nail 7 extends, the active tooth plate 25 will also move down through the elastic band 24. When the active tooth plate 25 moves down and stretches the tension spring, the driven tooth plate 27 can move up through the transmission wheel 26. The moving tooth plate 27 drives the insertion rod 29 to move up, so that the insertion rod 29 can extend out of the inner groove 28 and lock into the locking groove 32 to lock the position of the support rod 4.

[0062] Therefore, in this embodiment, after the support rod 4 is adjusted to a suitable position, the extension of the ground nail 7 and the locking of the support rod 4 can be completed or unlocked simultaneously, further improving the usability.
