They are one of the basic pieces of equipment to ensure measurement accuracy and operational efficiency. Their core function is to provide a stable support platform for the instruments and to meet the observation needs of different scenarios through adjustable structures.

[0003] A search revealed Chinese Patent Publication No. CN222363689U, which discloses a folding bracket and surveying device for a surveying instrument. The device includes a mounting connecting plate with three rotating support legs rotatably mounted on it. Telescopic support legs are slidably mounted on the rotating support legs, and a fixing structure is movably mounted on the telescopic support legs. The fixing structure consists of a base plate, racks, connecting rods, fixing springs, and anti-detachment baffles.

By setting a fixing structure on the telescopic support legs, the fixing and releasing of the telescopic and rotating support legs can be simplified and convenient, resulting in higher adjustment efficiency for the telescopic support legs and consequently, higher adjustment efficiency for the surveying equipment.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following defects: When existing surveying support devices are erected on soft sandy ground, muddy wetlands, or other surfaces with insufficient bearing capacity, the rigid legs of the support device have a small contact area with the ground. This can lead to the legs continuously sinking, causing the instrument to tilt and the measurement benchmark to shift. Repeated adjustments or even the use of wooden planks for support are required, which seriously affects work efficiency. Utility Model Content

[0005] To address the problems mentioned in the background art, this application provides a detachable adaptive terrain mapping support device.

[0006] This application provides a detachable adaptive terrain mapping support device, which adopts the following technical solution: A detachable adaptive terrain mapping support device includes a support device body and a measuring device. The support device body is installed at the bottom of the measuring device. A connection and disassembly assembly is installed at the bottom of the support device body. The connection and disassembly assembly includes a movable ring. A fixed ring is threadedly connected to the surface of the movable ring. A support ring is installed at the bottom of the fixed ring. A movable support assembly including a support column is provided at the bottom of the support device body. An installation groove is opened at the bottom of the support column. An electric push rod is installed inside the installation groove. A connecting ring is provided at the output end of the electric push rod. An inclination sensor is installed at the bottom of the support ring. The inclination sensor is electrically connected to a controller through a wire. The controller is electrically connected to the electric push rod through a wire.

[0007] The above solution enables the detachable replacement of the support ring through the threaded connection between the movable ring and the fixed ring. The electric push rod automatically adjusts the lifting and lowering of the connecting ring according to the tilt data monitored in real time by the tilt sensor, dynamically compensating for the difference in ground elevation, keeping the support ring horizontal, and solving the problem of measurement benchmark offset caused by the sinking of the support legs in traditional brackets.

[0008] Optionally, a connecting block is installed at the output end of the electric push rod, a buffer ring is installed at the bottom of the connecting block, the bottom of the buffer ring is installed with the top of the connecting ring, and an expansion groove is provided on the outer side of the buffer ring.

[0009] Through the above scheme, the connecting block transmits the power of the electric push rod to the connecting ring. The buffer ring absorbs ground vibration and impact through the elastic deformation of the expansion groove, reduces the rigid stress on the electric push rod, avoids equipment damage due to sudden changes in terrain, and improves the stability of the leveling process.

[0010] Optionally, the top of the buffer ring is provided with a mounting hole, and a buffer spring is provided inside the mounting hole. One end of the buffer spring is installed with the top of the connecting ring, and the other end of the buffer spring is installed with the bottom of the connecting block.

[0011] With the above scheme, the buffer spring is installed between the buffer ring and the connecting block. The compression and tension characteristics of the buffer spring 9 are used to further buffer the impact force of the ground and alleviate the inertial effect when the outriggers are raised and lowered. Especially when leveling quickly on soft ground, it can reduce the amplitude of instrument shaking and improve measurement accuracy.

[0012] Optionally, a limiting ring is installed at the bottom of the support column, and a movable ring is slidably connected inside the limiting ring, with the bottom of the movable ring installed with the top of the connecting ring.

[0013] With the above solution, the limiting ring is fixed to the bottom of the support column, providing a vertical sliding track for the moving ring, limiting its lateral offset range, ensuring that the connecting ring rises and falls vertically under the drive of the electric push rod, and at the same time protecting the output end of the electric push rod, thus enhancing the safety of the electric push rod.

[0014] Optionally, an installation ring is installed at the bottom of the limiting ring, a positioning ring is threaded onto the surface of the installation ring, and an inclined ring is installed at the bottom of the positioning ring.

[0015] The above solution secures the tilting ring by connecting the mounting ring and the positioning ring with threads. During use, the tilting ring can scrape and clean the surface of the moving ring as it moves, preventing impurities from entering the limiting ring and causing the moving ring to malfunction.

[0016] Optionally, an anti-slip ring is installed at the bottom of the connecting ring, and a support strip is installed on the outside of the anti-slip ring. Several support strips are provided, and the several support strips are arranged at equal intervals.

[0017] The above solution increases the friction coefficient between the support strip at the bottom of the anti-slip ring and the ground, preventing the outriggers from slipping on wet or loose ground. The equidistant distribution of several support strips evenly distributes the pressure of the outriggers to the ground, reducing the pressure per unit area and minimizing the risk of sinking in soft sand or muddy ground.

[0018] Optionally, a protective box is provided at the bottom of the controller, and the top of the protective box is installed with the bottom of the support ring.

[0019] The above solution protects the controller from rain and dust, improving the reliability of outdoor operations.

[0020] Optionally, a universal joint is installed at the top of the support column, and a rotating ring is installed at the top of the universal joint, with the top of the rotating ring sliding and rotating with the bottom of the support ring.

[0021] The above solution allows the universal joint to swing freely within a certain range, and the rotating ring enables the relative rotation between the support ring and the bracket body. The angle of the outriggers can be quickly adjusted without disassembling the entire bracket, thus improving the efficiency of multi-terrain operations.

[0022] In summary, this application includes the following beneficial technical effects:

[0023] 1. This utility model, by setting up an inclination sensor, a controller and an electric push rod, monitors the tilt data of the support ring in real time through the inclination sensor and transmits it to the controller. The controller controls the electric push rod to adjust the lifting and lowering of the connecting ring, so that the support ring can dynamically compensate for the difference in ground level and maintain a horizontal position. Thus, the device can automatically adapt to soft sand, muddy wetlands and other ground with insufficient bearing capacity, and avoid the effect of the support legs sinking, which would cause the instrument to tilt and the measurement reference to shift.

[0024] 2. By setting up a buffer ring and a buffer spring, the buffer ring absorbs ground vibration through elastic deformation of its expansion groove, and the buffer spring relieves inertial impact through compression and stretching. This creates a flexible transmission structure between the connecting block and the connecting ring, thereby achieving the effect of reducing instrument sway amplitude, improving measurement accuracy, and reducing rigid wear of the electric push rod when the terrain changes abruptly or is quickly leveled.

[0025] 3. This utility model, by setting a limiting ring, a moving ring, a mounting ring, a positioning ring, and an tilting ring, allows the moving ring to slide within the limiting ring to finely adjust the horizontal position of the connecting ring. The tilting ring adjusts the angle through threads and scrapes away impurities from the surface of the moving ring, enabling the support ring to conform to non-planar terrain such as slopes and steps. At the same time, it keeps the moving mechanism clean and smooth, thereby achieving the effect that this device can quickly adapt to complex terrains such as slopes and gravel ground, avoid the outriggers from being suspended or stuck, and improve the efficiency of multi-scenario operations.

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0032] This application discloses a detachable adaptive terrain mapping support device.

[0033] Please see Figures 1 to 4 A detachable adaptive terrain mapping support device includes a support body 1 and a measuring device 2. The support body 1 is installed at the bottom of the measuring device 2. A connection and disassembly assembly 3 is installed at the bottom of the support body 1. The connection and disassembly assembly 3 includes a movable ring 31. A fixed ring 32 is threadedly connected to the surface of the movable ring 31.

A movable support assembly 4 is provided at the bottom of the support body 1. The movable support assembly 4 includes a support column 41. An installation groove 42 is opened at the bottom of the support column 41. An electric push rod 43 is installed inside the installation groove 42 for automatically adjusting the support height according to the terrain. A connecting ring 44 is provided at the output end of the electric push rod 43. An inclination sensor 45 is installed at the bottom of the support ring 33. The inclination sensor 45 is electrically connected to a controller 46 through a wire. The controller 46 is electrically connected to the electric push rod 43 through a wire. The inclination sensor 45 is used to detect the tilt angle.

[0034] Please see Figures 3 to 4 The output end of the electric actuator 43 is equipped with a connecting block 5, and a buffer ring 6 is installed at the bottom of the connecting block 5. The bottom of the buffer ring 6 is installed with the top of the connecting ring 44. The outer side of the buffer ring 6 is provided with a telescopic groove 7, which absorbs ground vibration and impact through elastic deformation, reducing the rigid force on the electric actuator 43. The top of the buffer ring 6 is provided with a mounting hole 8, and a buffer spring 9 is installed inside the mounting hole 8. One end of the buffer spring 9 is installed with the top of the connecting ring 44, and the other end of the buffer spring 9 is installed with the bottom of the connecting block 5. The buffer spring 9 utilizes its compression and tension properties to absorb ground vibration and impact. To further buffer the impact and reduce the amplitude of instrument shaking, an anti-slip ring 15 is installed at the bottom of the connecting ring 44, and a support bar 16 is installed on the outside of the anti-slip ring 15. Several support bars 16 are provided and are arranged at equal intervals. The support bars 16 are used to increase the coefficient of friction with the ground, disperse the pressure of the outriggers, and reduce the risk of sinking in soft ground. A protective box 17 is provided at the bottom of the controller 46. The top of the protective box 17 is installed at the bottom of the support ring 33.

The bottom of the moving ring 11 is installed with the top of the connecting ring 44.

An installation ring 12 is installed at the bottom of the limiting ring 10. A positioning ring 13 is threadedly connected to the surface of the installation ring 12. An inclined ring 14 is installed at the bottom of the positioning ring 13. The inclined ring 14 is used to scrape off impurities from the surface of the moving ring 11 and prevent foreign objects from entering the gap of the limiting ring 10. A universal joint 19 is installed at the top of the support column 41. A rotating ring 20 is installed at the top of the universal joint 19. The top of the rotating ring 20 slides and rotates with the bottom of the support ring 33.

[0036] The implementation principle of the detachable adaptive terrain mapping support device in this application embodiment is as follows:

[0037] The high-precision tilt sensor 45 at the bottom of the bracket uses the principle of gravity sensing to monitor the change of the angle between the bracket and the horizontal plane at all times. When the bracket tilts due to soft ground, unevenness, or other reasons, the sensitive element inside the sensor shifts accordingly, causing changes in electrical parameters such as capacitance, resistance, or voltage, and then accurately converts this physical tilt into an electrical signal output.

[0038] After receiving the electrical signal from the tilt sensor 45, the controller 46 analyzes the signal according to a preset complex algorithm. This algorithm comprehensively considers the direction and magnitude of the angle deviation feedback from the sensor and accurately calculates the height adjustment required for each support point to restore horizontality. Subsequently, the controller 46 converts these calculation results into pulse width modulation signals to drive the electric actuator 43, so as to accurately control the extension and retraction of the electric actuator 43. In hilly areas, when the support is tilted in multiple directions, the controller 46 can quickly process multiple sets of sensor signals and generate differentiated control commands for different electric actuators 43.

[0039] According to the signal sent by the controller 46, the electric push rod 43 drives the lead screw and nut mechanism through the motor to realize the linear extension and retraction of the push rod. The top of the push rod is firmly connected to the connecting ring 44. When the push rod extends or shortens, the connecting ring 44 drives the lower end of the support column 41 to rise and fall synchronously. According to the lever balance principle, the dynamic adjustment of the height of each support point can effectively offset the difference in ground level, causing the support ring 33 to quickly return to the horizontal state. Taking the sandy environment as an example, when some legs sink and cause the support to tilt, the electric push rod 43 at the corresponding position extends and raises the sunken side until the tilt sensor 45 reports that the support has returned to the horizontal state.

[0040] The carefully designed telescopic grooves 7 on the outer side of the buffer ring 6 are made of highly elastic rubber or silicone. When the support is subjected to sudden vibration or impact from the ground, these telescopic grooves 7 act like tiny springs and can quickly undergo elastic deformation. During the deformation process, the kinetic energy generated by the impact is efficiently converted into the elastic potential energy of the material, which greatly weakens the rigid impact force transmitted to the electric push rod 43 and other components. For example, when passing through rugged mountain roads, if stones on the ground impact the support, the telescopic grooves 7 will absorb most of the impact force first, reducing damage to the internal precision components.

[0041] The buffer spring 9 is installed between the buffer ring 6 and the connecting block 5, with its two ends tightly connected to both. When the support is subjected to vibration, the buffer spring 9 generates a reverse damping force during the stretching or compression process according to Hooke's Law, which is opposite to the direction of vibration, thereby effectively attenuating the frequency and amplitude of vibration. At the same time, the damping characteristics of the spring ensure that it will not produce excessive rebound after absorbing vibration energy, ensuring that the instrument remains stable and avoiding measurement errors caused by shaking. During rapid leveling, the spring damping buffer structure can smoothly absorb the inertial impact generated at the moment of leveling, ensuring measurement accuracy.

[0042] The limiting ring 10 and the moving ring 11 together form a precise sliding pair structure. The inner wall of the limiting ring 10 is smooth and has a specific shape and size. The moving ring 11 is tightly nested inside the limiting ring 10 and can only move linearly along the axial direction of the limiting ring 10. This design utilizes the linear motion constraint principle in mechanical kinematics to strictly limit the movement trajectory of the connecting ring 44 under the drive of the electric push rod 43, ensuring that it can only move vertically up and down, avoiding damage to the electric push rod 43 caused by lateral force due to lateral offset, and ensuring the stable operation of the support mechanism.

[0043] The inclined ring 14 is firmly connected to the positioning ring 13 by threads. Its inclined surface and the surface of the moving ring 11 form an ingenious scraping and cleaning structure. When the moving ring 11 moves up and down within the limiting ring 10, the inclined surface of the inclined ring 14 and the surface of the moving ring 11 always maintain close contact. Using the principle of mechanical friction, the mud, sand and gravel adhering to the surface of the moving ring 11 are scraped off one by one. The impurities slide down the inclined surface of the inclined ring 14, effectively preventing them from entering the gap between the limiting ring 10 and the moving ring 11, ensuring the long-term stable operation of the support mechanism and reducing failures caused by impurities getting stuck.

[0044] Several support strips 16 are evenly distributed at the bottom of the anti-slip ring 15. These support strips 16 are made of materials with high hardness and high friction coefficient. The support strips 16 increase the friction coefficient with the ground, thereby significantly improving the anti-slip ability of the support and evenly distributing the weight of the support itself and the load generated by the measuring equipment 2 to the ground. This effectively reduces the tendency to sink on soft ground. When working on muddy ground, the support strips 16 can penetrate into the ground to a certain depth, providing reliable anti-slip and support effects.

[0045] Disassembly can be performed simply by rotating the support ring 33, which causes the fixed ring 32 to rotate. The fixed ring 32 rotates and separates from the surface thread of the movable ring 31, making disassembly convenient.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
