[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0022] The following is for reference. Figure 1-2 A slope radar test frame according to an embodiment of the present invention is described.

[0023] This application proposes a slope radar test frame, which includes a support body, a guide rail assembly, a drive motor 2, a slope radar, and a positioning component. The support body includes multiple support units, each of which includes a leg 11 and a crossbeam 12, with the crossbeam 12 detachably connected to the leg 11. The guide rail assembly includes a frame 31 and a slider 32, with the frame 31 mounted on the support body and the slider 32 movably connected to the frame 31. The drive motor 2 is mounted on the support body and connected to the guide rail assembly to drive the slider 32 to move relative to the frame 31. The slope radar is mounted on the slider 32 to move with the slider 32. The positioning component is mounted on the guide rail assembly to position the slope radar.

[0024] According to the slope radar test frame of this application, the main support body provides stable support in the test scenario. The drive motor 2 and the guide rail assembly are set on the main support body. The drive motor 2 drives the guide rail assembly to move, enabling the slope radar to move. During the movement, the slope radar performs monitoring and testing. The positioning component enables the slope radar to be positioned to provide the position parameters for monitoring. Furthermore, the main support body includes multiple support units, each consisting of detachably connected legs 11 and crossbeams 12. On the one hand, the structure is reusable, allowing the main support body to be disassembled and assembled anytime and anywhere, facilitating movement and transportation. The legs 11 or crossbeams 12 can also be partially adjusted or replaced, shortening maintenance time and cost. On the other hand, by adding or removing the legs 11 and crossbeams 12 and selecting their dimensions, the height and width of the main support body can be adjusted to adapt to different simulated test scenarios, achieving flexible reconfiguration of the test frame. Furthermore, by adjusting the relative position of each support unit, it can adapt to different terrains to build different guide rail shapes (such as steep slope S-shaped tracks, mine stepped tracks), thereby simulating different test scenarios. The spatial angle of each support unit can be adjusted according to testing requirements.

[0025] In the prior art, the support structure of the slope radar testing device is usually made of welded steel. Compared with the existing integral welded steel frame, the support body of this application can be repeatedly disassembled and adjusted to achieve low-cost trial and error, improve the flexibility of structural assembly and adaptability to the testing environment, and eliminate welding operations, thereby reducing processing and maintenance costs.

[0026] According to the slope radar test frame of this application, due to the inclusion of a guide rail assembly, a drive motor 2, and positioning components, this application can simulate the dynamic process of slope radar monitoring and acquire slope radar movement parameters and monitoring results for research and analysis. Based on a high degree of simulation of slope radar monitoring operation, the application features a detachable support body composed of legs 11 and crossbeams 12, which simplifies the structure and assembly operations, improving assembly and maintenance efficiency; reduces testing costs; and enhances the flexibility of structural assembly and adaptability to testing environments, making it suitable for different testing scenarios. Using the test frame of this application to test the performance of slope radar can significantly shorten the "concept-proof" cycle and accelerate problem solving and technical solution upgrades.

[0027] In some embodiments, the support legs 11 and the crossbeam 12 can be modularly connected using threaded connectors such as screws. This connection method is simple and efficient, shortening the assembly time of the test frame and enabling rapid assembly and disassembly to meet emergency monitoring needs. Testing has shown that the main body of the support frame of this application can be erected within 10 minutes, while traditional welded steel frames require more than 2 hours. This application can meet emergency monitoring requirements. Furthermore, the support legs 11 and the crossbeam 12 have pre-set threaded holes or other connection holes to facilitate rapid connection during assembly.

[0028] According to some embodiments of this application, the positioning component includes a first proximity switch 51, a second proximity switch 52, a third proximity switch 53, and a proximity switch stop 54. The first proximity switch 51 and the second proximity switch 52 are disposed on the frame 31 and are respectively located near both ends of the frame 31. The third proximity switch 53 is disposed on the frame 31 and is positioned between the first proximity switch 51 and the second proximity switch 52. The proximity switch stop 54 is disposed on the slider 32 and is adapted to trigger a signal when it approaches the first proximity switch 51, the second proximity switch 52, or the third proximity switch 53. In this embodiment, the first proximity switch 51 and the second proximity switch 52 are located near both ends of the guide rail assembly. When the slope radar moves close, the trigger signal can serve as the starting point and ending point of the slope radar movement test, acting as a soft limit to prevent the test distance from exceeding the limit. The third proximity switch 53 is located in the middle position and can serve as a zero-return reference point, enabling the slope radar test frame to have a zero-return function, ensuring that multiple tests have a fixed benchmark, and improving the comparability and accuracy of the data. The positioning element in this embodiment can provide accurate position parameters for the testing and operation of the slope radar.

[0029] According to some embodiments of this application, the outriggers 11 and / or the crossbeams 12 are made of aluminum or plastic. In this embodiment, the outriggers 11 and crossbeams 12 are made of aluminum or plastic. Compared to the steel used in the prior art, this embodiment can reduce the structural weight, achieve lightweight design, and thus improve the convenience of structural movement and assembly, simplifying the assembly process. The density of the aluminum material is 2.7 g / cm³. 3 It is only 1 / 3 the size of steel.

[0030] Furthermore, the legs 11 and crossbeams 12 of the main support structure are both made of homogeneous aluminum, with a coefficient of thermal expansion of 23 × 10⁻⁶. -6The temperature is significantly lower than that of engineering plastics, and the track bending due to temperature changes is less than 0.05 mm / m, only about half that of steel rails. This low coefficient of thermal deformation results in high thermal stability, allowing the support structure to maintain its shape and high precision, thus reducing the impact on slope radar test results. Furthermore, aluminum exhibits low-temperature toughness, maintaining structural stability even in extremely cold regions (such as open-pit mines in Inner Mongolia) at -30℃, avoiding the risk of steel brittleness. This embodiment significantly improves the environmental adaptability of the test frame.

[0031] In some embodiments, the frame 31 and slider 32 of the guide rail assembly are also made of aluminum, which enables the weight of a 6-meter guide rail to be less than 15kg, significantly reducing the structural weight and achieving a lightweight design. Tests have shown that the support body and guide rail assembly are both made of aluminum, and compared with the welded steel frame in the prior art, the total weight of the test frame can be reduced by more than 40%.

[0032] According to some embodiments of this application, the support leg 11 and / or crossbeam 12 are made of a honeycomb structure. In this embodiment, the honeycomb structure can improve the structural strength of the support body and achieve a high-rigidity design, thereby ensuring the stability of the slope radar scanning posture during the test. In some embodiments, the support leg 11 and crossbeam 12 are made of 40mm×80mm honeycomb square tube profiles, which can achieve a bending stiffness ≥180N / mm. 2 .

[0033] According to some embodiments of this application, the surfaces of the legs 11 and / or the crossbeams 12 are provided with an anti-corrosion layer. In this embodiment, the anti-corrosion layer improves the acid and salt resistance of the support body, enabling the test frame of this application to be used in harsh environments such as acid rain and salt spray (e.g., coastal mining areas), thus extending the service life of the test frame. Testing has shown that this embodiment can extend the service life of the test frame by 3 to 5 times. Furthermore, the anti-corrosion layer can be formed by anodizing the surface of the support body structure. Compared to existing welded steel frame structures, this embodiment also eliminates the need for subsequent rust removal and maintenance, reducing maintenance costs.

[0034] According to some embodiments of this application, the support body also includes casters 6, which are correspondingly disposed at the bottom of a plurality of support legs 11 and detachably connected to the support legs 11. In this embodiment, as... Figure 2 As shown, the casters 6 facilitate the movement of the slope radar test frame, enabling long-distance movement to the test position. Furthermore, to improve stability during the testing process, the casters 6 are used temporarily during the movement of the slope radar test frame and are removed after the movement is complete, ensuring the main body of the support remains stable in the test position and guaranteeing the accuracy and reliability of the test. Further, to further simplify the test frame structure, such as... Figure 2As shown, casters 6 are installed in at least two sets of support units, and the number can be adjusted according to stability requirements.

[0035] According to some embodiments of this application, the drive motor 2 and the guide rail assembly are connected by a synchronous belt drive mechanism. In this embodiment, by setting a synchronous belt drive mechanism, flexible transmission is achieved using a synchronous belt, which can absorb and reduce vibration, reduce operating noise, maintain structural stability, and provide a certain degree of protection for the slope radar. At the same time, the synchronous belt drive can eliminate the need for lubrication required by gears, lead screws, and other transmissions, simplifying the structure and operation; it can also reduce replacement costs and improve maintenance convenience. Furthermore, the drive motor 2 is a stepper motor, which can achieve millimeter-level repeatability positioning with no cumulative error using open-loop control, achieving accurate positioning of the slope radar; and its simple structure eliminates the need for an encoder feedback system, further reducing costs. Moreover, the drive motor 2 in this embodiment has a flexible layout, allowing for remote installation and optimizing the center of gravity distribution of the test frame, making it particularly suitable for light-load, low-to-medium speed testing scenarios.

[0036] According to some embodiments of this application, the support body further includes a connecting beam 13, which connects two adjacent support units. In this embodiment, connecting two adjacent support units with the connecting beam 13 can improve the structural stability of the support body. In some embodiments, a crossbeam 12 is connected to two legs 11 to form a support unit, and multiple support units can be connected together by the connecting beam 13 to form a stable overall support body structure. Further, the support unit can be constructed as three units, and the six legs 11 improve the applicability of the test frame under different test conditions.

[0037] According to some embodiments of this application, the bracket body further includes a fixing corner piece 14, which connects the crossbeam 12 and the connecting beam 13, and is adapted to adjust the connection angle between the crossbeam 12 and the connecting beam 13. For example... Figure 1 As shown, the fixing angle piece 14 is located at the angle between the crossbeam 12 and the connecting beam 13, and is detachably fixed to both the crossbeam 12 and the connecting beam 13. By adjusting the structural angle of the fixing angle piece 14, or by selecting different fixing angle pieces 14, the connection angle between the crossbeam 12 and the connecting beam 13 can be adjusted, thereby changing the overall shape of the support body to adapt to different terrains and different guide rail shapes (such as steep slope S-shaped tracks and mine stepped tracks), thus simulating different test scenarios. Furthermore, the support leg 11, crossbeam 12, connecting beam 13, and fixing angle piece 14 all have screw holes to achieve stable connection and assembly using screws and other fasteners.

[0038] In some embodiments, the legs 11 and the crossbeams 12 are made of square tubular profiles and have end caps at the ends to form a closed structure, which provides a certain degree of protection for the interior of the structure, and is waterproof and dustproof.

[0039] According to some embodiments of this application, the slope radar test frame further includes an adapter plate 4, which is disposed on the slider 32 to be adapted to move with the slider 32. The adapter plate 4 is suitable for mounting the slope radar. In this embodiment, the slope radar can be stably installed by setting the adapter plate 4, and the adapter plate 4 is easy to replace and can be matched with different guide rail components. The adapter plate 4 can be manufactured by 3D printing, which has high processing efficiency, fast replacement and iteration speed, small processing error, and high compatibility with guide rail components and slope radar; and in some embodiments, resin printing can be used, which has low processing cost.

[0040] In this application, the support legs 11 and the crossbeam 12 can be made of aluminum profiles. Aluminum profiles are modular standard structures with standardized basic structural strength and stability; they can be easily and flexibly reconfigured in various combinations to meet different testing needs; they are easy to assemble and adjust, and convenient for long-distance movement; the material is pure, and homogeneous aluminum alloy can reduce deformation interference caused by residual welding stress in steel, ensuring that test data reflects "radar performance" rather than "frame defects"; thermal deformation is controllable, and by simulating high and low temperature environments in a temperature-controlled experimental chamber, the impact of thermal expansion and contraction of aluminum profiles on the accuracy of slope radar scanning can be directly quantified, providing accurate reference for research and analysis.

[0041] Furthermore, in this application, the aforementioned drive motor 2, guide rail assembly, synchronous belt drive mechanism, and various proximity switches can all adopt common standardized structural components, which are easy to purchase and obtain, greatly reducing testing costs and saving the high cost of customizing corresponding structures; and the standardized finished products have been practically verified, with low failure rate and good stability, which can ensure the reliability of power, movement and positioning, and avoid the test results being affected by the failure of the test frame.
