Description

Technical Field

[0001] This application belongs to the field of center of gravity detection technology, specifically relating to a steel structure balance center of gravity detection device. Background Technology

[0002] Steel structural components are the core load-bearing and stress-bearing carriers, and their center of gravity position directly determines the stress distribution, operational stability, and service life of the overall structure. If the center of gravity of a steel structural component shifts, it may lead to localized stress concentration, decreased seismic performance, or accelerated mechanical wear. Therefore, accurate detection of the center of gravity of steel structural components is a crucial step in ensuring project safety and improving equipment reliability, and it plays an irreplaceable role in production, manufacturing, and safety management.

[0003] As shown in the patent with publication number CN118347635A, the existing center of gravity detection device includes a gantry frame for suspending the workpiece under test. The top of the gantry frame is equipped with a lifting component consisting of a suspension rope and a first electromagnet suction cup. The lifting component needs to be attached to the middle of the workpiece under test for positioning. A detection platform is located directly below the workpiece under test. A horizontal slide rail on the detection platform is slidably connected to a sliding seat with a support column. Laser rangefinders arranged in a straight line are installed at the top of the support column to collect distance data of the same surface of the workpiece under test. The device also includes a magnet or a telescopic cylinder with a connector as a driving component to drive the workpiece under test to a horizontal state to obtain weight data.

[0004] However, such detection devices are not suitable for detecting irregular steel structures. The lifting component needs to rely on adsorbing the center of the test piece for positioning, but irregular steel structures lack a flat and uniform central adsorption surface, causing the first electromagnet chuck to fail to adsorb stably, resulting in inaccurate initial positioning. The laser rangefinder sensor needs to calculate the tilt angle based on the distance data of the same surface, but the surface morphology of irregular steel structures is complex, making it difficult for the sensor to obtain continuous and uniform measurement data, causing the angle calculation logic to fail. The driving component needs to apply force to the test piece through adsorption or overlay to drive it to a horizontal state, but the irregular contour of the irregular steel structure makes it difficult for the driving component to stably contact the force application point, making it difficult to accurately adjust to a horizontal state, ultimately causing inaccurate center of gravity detection or even failure to complete the detection. Summary of the Invention

[0005] This application addresses the problem that existing testing devices cannot be adapted to irregular steel structures by providing a steel structure balance center of gravity testing device, which can realize the detection of the center of gravity of irregular steel structures.

[0006] To address the above problems, the technical solution adopted in this application is a steel structure balance center of gravity detection device, including a support base, a control mechanism on the support base, and a main drive component on the support base. The output end of the main drive component is connected to the bottom of a vertically arranged rotating mounting ring. The main drive component can drive the rotating mounting ring to rotate around its own vertical axis. A detection mechanism is provided at the top of the rotating mounting ring, which can detect the motion parameters of the rotating mounting ring. An adjustment mounting ring is provided inside the rotating mounting ring. Two sets of adjustment mechanisms are rotatably connected to the outer wall of the adjustment mounting ring. The two sets of adjustment mechanisms are symmetrically distributed along the radial direction of the adjustment mounting ring. The adjustment mounting ring can rotate around the line connecting the two sets of adjustment mechanisms, and both sets of adjustment mechanisms can slide along the inner wall of the rotating mounting ring. A clamping mechanism is provided on the inner wall of the adjustment mounting ring, which can clamp and fix the steel structure to be tested.

[0007] In this technical solution, a control mechanism and a main drive component are mounted on the support base. The output end of the main drive component is connected to the bottom of a vertically arranged rotating mounting ring, driving the rotating mounting ring to rotate around its vertical axis. The top of the rotating mounting ring has a detection mechanism to detect its motion parameters, and inside is an adjusting mounting ring. The outer wall of the adjusting mounting ring is rotatably connected to two sets of adjusting mechanisms symmetrically distributed radially. The adjusting mounting ring can rotate around the line connecting the two sets of adjusting mechanisms, and the two sets of adjusting mechanisms can slide along the inner wall of the rotating mounting ring. The inner wall of the adjusting mounting ring also has a clamping mechanism for clamping and fixing the steel structure to be tested. During actual testing, the steel structure to be tested is first clamped and fixed by the clamping mechanism. Then, the rotating mounting ring is controlled to rotate by the control mechanism, and the position of the adjusting mounting ring is adjusted so that the overall center of gravity of the device and the steel structure is centered. Subsequently, the steel structure is removed, and the rotating mounting ring is controlled to rotate again. The spatial position of the overall center of gravity at this time is the center of gravity position of the steel structure to be tested. In summary, this device can effectively detect the center of gravity of irregular steel structures.

[0008] Furthermore, the support base has a fixed mounting strip on its side wall, a support rotating sleeve on its top, a power supply ring on its inner side wall, and a support rotating slider inside the support rotating sleeve. The top of the support rotating slider is fixedly connected to the rotating mounting ring, and the outer side wall of the support rotating slider slides against the inner side wall of the support rotating sleeve. A rotating brush is located on the outer side wall of the support rotating slider and slides against the power supply ring. The fixed mounting strip on the side wall of the support base provides a stable external mounting point for the entire device, enhancing its placement stability during testing and preventing displacement caused by equipment operation from affecting testing accuracy. The support rotating sleeve on the top of the support base cooperates with the internal support rotating slider. On one hand, the fixed connection between the top of the support rotating slider and the rotating mounting ring provides bottom support for the rotating mounting ring, ensuring stable rotation around the vertical axis and reducing shaking during rotation. On the other hand, the sliding contact between the outer side wall of the support rotating slider and the inner side wall of the support rotating sleeve limits the radial displacement of the rotating mounting ring, further improving rotational smoothness.

[0009] Furthermore, a top mounting plate is located directly above the rotating mounting ring. Several equally spaced arc-shaped support rods are positioned between the top mounting plate and the support base. Gaps are left between the arc-shaped support rods and the rotating mounting ring, and arc-shaped reinforcing rods are positioned between adjacent arc-shaped support rods. The top mounting plate directly above the rotating mounting ring serves as the mounting base for the upper structure, providing support for subsequent additions of limit switches and related detection components. The equally spaced arc-shaped support rods between the top mounting plate and the support base evenly distribute the weight of the top mounting plate while providing a surrounding protection for the rotating mounting ring, preventing external objects from interfering with its operation. The gaps between the arc-shaped support rods and the rotating mounting ring prevent friction and collision during rotation, ensuring smooth rotation of the ring. The arc-shaped reinforcing rods between adjacent arc-shaped support rods enhance the connection strength between them, improving the stability and deformation resistance of the overall support structure. This prevents the support rods from loosening or deforming due to vibrations generated during equipment operation, further ensuring the installation stability of the top mounting plate and subsequent components, and indirectly improving the accuracy of center of gravity detection.

[0010] Furthermore, a limiting rotation groove is formed at the bottom of the top mounting plate. The top of the limiting rotation groove is connected to the stable cavity inside the top mounting plate. A limiting rotation column is provided inside the limiting rotation groove, and the detection mechanism is located at the upper end of the limiting rotation column. The lower end of the limiting rotation column is fixedly connected to the top of the rotating mounting ring. A limiting rotation sleeve is provided at the bottom of the top mounting plate, and a limiting rotation slider is provided inside the limiting rotation sleeve. The bottom of the limiting rotation slider is fixedly connected to the rotating mounting ring. The limiting rotation groove at the bottom of the top mounting plate cooperates with the internal limiting rotation column. The lower end of the limiting rotation column fixes the rotating mounting ring, and the upper end mounts the detection mechanism. This allows the rotating mechanism to rotate synchronously with the rotating mounting ring and also limits the radial offset of the rotating mounting ring through the limiting rotation groove, ensuring that the rotating mounting ring always rotates stably around the vertical axis. At the same time, it provides a stable mounting carrier for the detection mechanism, ensuring that the detection mechanism can accurately collect rotation parameters. The limiting rotation groove is connected to the stable cavity inside the top mounting plate. The stable cavity can absorb the vibration energy generated during rotation, weaken the impact of vibration on the limiting rotation column and the detection mechanism, and reduce the error of the detection data. The limiting rotating sleeve at the bottom of the top mounting plate cooperates with the internal limiting rotating slider. The bottom of the limiting rotating slider is fixed with a rotating mounting ring, which can form a double limiting structure with the limiting rotating groove and the limiting rotating column, further restricting the shaking of the rotating mounting ring, improving the overall rotational stability, and avoiding inaccurate center of gravity detection results due to rotational offset.

[0011] Furthermore, the adjustment mechanism includes a limiting guide block, the side wall of which has a power supply groove. A rotary drive component is located on the side of the limiting guide block near the adjustment mounting ring, and the output end of the rotary drive component is fixedly connected to the outer wall of the adjustment mounting ring. The inner wall of the rotation mounting ring has a limiting guide groove, and the side wall of the limiting guide groove has a power supply slide rail located within the power supply groove. The limiting guide block in the adjustment mechanism cooperates with the limiting guide groove on the inner wall of the rotation mounting ring, guiding the sliding of the adjustment mechanism along the inner wall of the rotation mounting ring and ensuring smooth and non-deviationing sliding. The power supply groove on the side wall of the limiting guide block cooperates with the power supply slide rail on the side wall of the limiting guide groove, and the power supply slide rail located within the power supply groove, providing continuous power supply during the sliding of the adjustment mechanism and ensuring the stable operation of components such as the rotary drive component. The output end of the rotary drive component on the limit guide block is fixedly connected to the outer wall of the adjustment mounting ring, which can drive the adjustment mounting ring to rotate around the line connecting the two sets of adjustment mechanisms, thereby realizing the angle adjustment of the adjustment mounting ring. Combined with the sliding function of the adjustment mechanism, the position and angle of the adjustment mounting ring can be flexibly changed to adapt to steel structures of different shapes, providing multi-dimensional adjustment capabilities for center of gravity adjustment.

[0012] Furthermore, the inner wall of the rotating mounting ring is equipped with a displacement ring, and the limiting guide block is also equipped with two rotating wheel frames. The two rotating wheel frames are symmetrically distributed about the rotating drive component, and each rotating wheel frame is equipped with a displacement drive wheel. The outer circumferential surface of the displacement drive wheel is in contact with the displacement ring. The displacement ring on the inner wall of the rotating mounting ring is in contact with the displacement drive wheel on the limiting guide block. The rotation of the displacement drive wheel can drive the adjustment mechanism to slide stably along the inner wall of the rotating mounting ring, providing power for the movement of the adjustment mechanism. The symmetrical distribution of the two rotating wheel frames about the rotating drive component can make the force of the displacement drive wheel on the displacement ring balanced, avoiding deviation or jamming due to uneven force during the sliding of the adjustment mechanism, and ensuring the smoothness of the sliding process. This symmetrical distribution structure can also enhance the connection stability between the adjustment mechanism and the rotating mounting ring. Combined with the guiding effect of the limiting guide block and the limiting guide groove, it can further improve the accuracy of the adjustment of the mounting ring position, making it easier to achieve overall center of gravity centering more efficiently.

[0013] Furthermore, the inner wall of the adjusting mounting ring is provided with a displacement guide groove, and the side wall of the displacement guide groove is provided with a conductive slide rail. Several displacement guide blocks are provided within the displacement guide groove, and each displacement guide block has a conductive slide groove on its side wall, which is fitted onto the conductive slide rail. Each displacement guide block is provided with a displacement mounting plate, and the number of clamping mechanisms is the same as the number of displacement mounting plates, which are mounted on the corresponding displacement mounting plates. The displacement guide groove on the inner wall of the adjusting mounting ring cooperates with the displacement guide blocks to guide the sliding of the displacement guide blocks, ensuring their smooth movement along the inner wall of the adjusting mounting ring. The conductive slide rail on the side wall of the displacement guide groove engages with the conductive slide groove on the side wall of the displacement guide block, ensuring continuous conductivity during the sliding of the displacement guide block and guaranteeing the power supply to the clamping mechanism. Several displacement guide blocks are connected to the clamping mechanism through displacement mounting plates, which allows multiple clamping mechanisms to flexibly adjust their positions along the inner wall of the adjusting mounting ring, adapting to steel structures of different sizes and shapes, realizing multi-point clamping and fixing, improving the stability of steel structure clamping, and providing a reliable fixed foundation for center of gravity detection.

[0014] Furthermore, each displacement guide block is equipped with floating wheel frames on both sides. An elastic element is installed between the floating wheel frames and the displacement mounting plate. Several movable drive wheels are mounted on the floating wheel frames, with their outer circumferential surfaces fitting against the inner wall of the adjusting mounting ring. The cooperation between the floating wheel frames on both sides of the displacement guide block and the movable drive wheels fitting against the inner wall of the adjusting mounting ring provides power for the movement of the displacement guide block along the inner wall of the adjusting mounting ring, ensuring that the displacement guide block can flexibly adjust its position to adapt to the clamping requirements of the steel structure. The elastic element between the floating wheel frames and the displacement mounting plate provides a buffering effect. When there are minor unevennesses on the inner wall of the adjusting mounting ring or when the displacement guide block encounters slight resistance during movement, the elastic element can adaptively adjust the position of the floating wheel frames, ensuring that the movable drive wheels are always in close contact with the inner wall of the adjusting mounting ring, avoiding slippage or jamming, and guaranteeing the smooth movement of the displacement guide block. Simultaneously, the elastic element also weakens vibrations generated during movement, reducing the impact on the clamping stability of the clamping mechanism and indirectly improving the accuracy of the center of gravity detection.

[0015] Furthermore, the clamping mechanism includes a cross-shaped mounting post fixed to a strain gauge mounting plate. The cross-shaped mounting post has one electric telescopic rod and two guide telescopic rods symmetrically distributed on both sides of the electric telescopic rod. The telescopic ends of the electric telescopic rod and the guide telescopic rods are connected to the telescopic mounting plate. A steering drive component is located on the side of the telescopic mounting plate away from the cross-shaped mounting post. The output end of the steering drive component is connected to a steering mounting frame. Two symmetrically arranged swing telescopic rods are mounted on the steering mounting frame. The cylinders of the swing telescopic rods are rotatably connected to the steering mounting frame. The telescopic ends of the swing telescopic rods are connected to one end of an elastic connecting block, and the other end of the elastic connecting block has a clamping plate. The clamping plates on the two swing telescopic rods are arranged opposite each other, and anti-slip horizontal grooves are provided on the opposite surfaces of the clamping plates. In the clamping mechanism, the cross-shaped mounting post provides a stable mounting base for the electric telescopic rod and the guide telescopic rods. The two guide telescopic rods symmetrically distributed on both sides of the electric telescopic rod guide the telescopic mounting plate when it is driven to move, preventing the telescopic mounting plate from shifting and ensuring that the clamping plate is accurately positioned close to the steel structure. The steering drive unit rotates the steering mounting bracket, adjusting the orientation of the clamping plates to accommodate clamping requirements at different angles on steel structures. Two symmetrically arranged swing telescopic rod cylinders are rotatably connected to the steering mounting bracket, with their telescopic ends connected to the clamping plates via elastic connecting blocks. This allows for adjustment of the clamping angle through swinging and changes in the clamping distance through telescopic extension, accommodating steel structures of different sizes and shapes. The elastic connecting blocks provide cushioning during clamping, preventing damage to the steel structure surface from rigid clamping and ensuring a better fit between the clamping plates and irregular steel structure surfaces. The clamping plates are positioned opposite each other, with anti-slip horizontal grooves on their opposing surfaces. This enhances the friction between the plates and the steel structure, preventing loosening or slippage during inspection, ensuring clamping stability, and providing reliable conditions for accurate detection of the center of gravity.

[0016] Furthermore, the control mechanism includes a balancing mounting base, which is fixedly connected to the support base. The bottom of the balancing mounting base has a rubber ring, and the side wall has a mounting plate. The balancing mounting base is equipped with a display, keyboard, touchpad, and expansion interface. The fixed connection between the balancing mounting base and the support base provides a stable mounting foundation for the control components, ensuring a secure connection between the control mechanism and the main body of the device. The rubber ring at the bottom of the balancing mounting base increases friction with the placement surface, reducing vibration transmission during device operation and preventing wear caused by direct contact between the balancing mounting base and the placement surface, thus improving overall placement stability. The mounting plate on the side wall of the balancing mounting base can be used to additionally fix or expand external auxiliary components, enhancing the functional expandability of the control mechanism. The display on the balancing mounting base can intuitively display detection data and equipment operating status. The keyboard and touchpad facilitate operator input of commands and parameter adjustment. The expansion interface allows connection to external devices such as data storage devices or printing equipment, facilitating data export and subsequent processing, thus improving the overall ease of operation and practicality of the device.

[0017] As can be seen from the above technical solutions, the beneficial effects of this application are as follows: 1. It can flexibly adapt to irregular steel structures. Through the multi-dimensional adjustable mounting ring and movable clamping mechanism, it can achieve stable clamping and center of gravity adjustment to meet different testing needs.

[0018] 2. Strong operational stability: Multiple limiting structures, symmetrically distributed support and drive components, combined with the vibration reduction effect of the steady-state cavity, reduce equipment shaking and detection errors, and ensure detection accuracy.

[0019] 3. Convenient operation and power supply: The continuous sliding power supply design avoids wire problems. The display, input and expansion components of the control mechanism facilitate parameter adjustment and data processing, improving ease of use. Attached Figure Description

[0033] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this application, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0034] A steel structure balance center of gravity detection device, such as Figure 1-5 As shown, the entire system consists of five core modules: a support base, a drive rotation component, a stabilizing and limiting component, an adjusting and clamping component, and a control and interaction component. The support base provides the installation support and a fixed foundation for the entire device. The drive rotation component rotates the steel structure and related adjusting components to simulate the detection state. The stabilizing and limiting component reduces rotational vibration and restricts component offset, ensuring stable detection. The adjusting and clamping component enables multi-dimensional clamping and center-of-gravity adjustment of the steel structure. The control and interaction component is responsible for power supply, parameter control, data acquisition and display, and external device expansion. These modules work together to achieve stable clamping of the steel structure, multi-dimensional center-of-gravity adjustment, motion parameter detection, and human-machine interaction control. Multiple sets of sliding conductive structures ensure continuous power transmission during rotation. The specific connection relationships of each component and the power transmission method are described in detail below: The core of the supporting base components is the support base 2, which is horizontally positioned. A balance mounting base 1 for the control and interaction components is fixedly connected to one side of the support base 2. Both the bottom of the balance mounting base 1 and the bottom of the support base 2 are equipped with rubber rings 9, which directly contact the placement surface, enhancing the overall stability of the device and reducing operational vibration. The side wall of the balance mounting base 1 is equipped with a mounting plate 19, which has pre-drilled mounting holes for external fixation of the device.

[0035] like Figure 6 As shown, a display 20 is located on the front of the balance mounting base 1. Below the display 20, on the front of the balance mounting base 1, a keyboard 21, a touchpad 22, and several expansion interfaces 23 are sequentially arranged. A processing unit is integrated on the rear of the display 20. The processing unit is connected to the display 20, keyboard 21, touchpad 22, and expansion interfaces 23 via wires, forming a basic human-computer interaction and data processing link. The expansion interfaces 23 can be connected to external data storage or printing devices to export and retain test data. A mounting strip 18 is provided on the side wall of the support base 2 away from the balance mounting base 1. The mounting strip 18 also has pre-drilled mounting holes, which cooperate with the mounting plate 19 on the balance mounting base 1 to further improve the flexibility and stability of the device installation.

[0036] A supporting rotating sleeve 17 is fixedly installed on the top of the supporting base 2. The supporting rotating sleeve 17 has a ring-shaped structure, and a power supply ring 5 is fixedly attached to its inner side wall. The power supply ring 5 is connected to the processing unit inside the balance mounting base 1 through a hidden wire, forming the starting point of power transmission. A supporting rotating slider 11 is movably embedded inside the supporting rotating sleeve 17. The outer side wall of the supporting rotating slider 11 is slidably attached to the inner side wall of the supporting rotating sleeve 17, and a rotating brush 36 is fixedly provided on the outer side wall of the supporting rotating slider 11. The rotating brush 36 is tightly slidably attached to the power supply ring 5, forming a sliding conductive pair.

[0037] As the supporting rotating slider 11 rotates with the component, the rotating brush 36 remains in contact with the power supply ring 5, ensuring continuous power transmission to the supporting rotating slider 11. The top of the supporting rotating slider 11 is fixedly connected to the bottom of the core rotating mounting ring 6 of the driving rotating component. The rotating mounting ring 6 is vertically arranged, and the main driving component 10 is also fixedly mounted on the support base 2. The output end of the main driving component 10 is connected to the bottom of the rotating mounting ring 6 via a transmission line. The main driving component 10 is controlled by the processing unit through wires. After being powered on, it can drive the rotating mounting ring 6 to rotate around its own vertical axis, and at the same time drive the supporting rotating slider 11 to rotate synchronously within the supporting rotating sleeve 17. At this time, power is transmitted to the supporting rotating slider 11 through the power supply ring 5 and the rotating brush 36, and then transmitted to the various electrical components on the rotating mounting ring 6 through wires, completing the first stage of power transmission.

[0038] A top mounting plate 8 with a stabilizing and limiting component is located directly above the rotating mounting ring 6. Several equally spaced arc-shaped support rods 3 are fixedly connected between the top mounting plate 8 and the support base 2. The two ends of each arc-shaped support rod 3 are fixed to the edge of the top mounting plate 8 and the top edge of the support base 2, respectively. A gap is left between the arc-shaped support rods 3 and the rotating mounting ring 6 to prevent friction during rotation. Arc-shaped reinforcing rods 4 are also fixedly connected between adjacent arc-shaped support rods 3. These reinforcing rods 4 are evenly spaced horizontally to further enhance the support strength between the top mounting plate 8 and the support base 2, ensuring the stability of the top mounting plate 8.

[0039] like Figure 7 As shown, the bottom of the top mounting plate 8 has an annular limiting rotation groove 25. The top of the limiting rotation groove 25 is connected to a stable cavity 24 inside the top mounting plate 8. The stable cavity 24 is filled with vibration damping material to absorb vibrations during rotation. A limiting rotation post 14 is movably embedded in the limiting rotation groove 25. The lower end of the limiting rotation post 14 is fixedly connected to the top of the rotating mounting ring 6 and rotates synchronously with the rotating mounting ring 6.

[0040] like Figure 8As shown, a detection mechanism is fixedly installed at the upper end of the limiting rotation column 14. The detection mechanism includes a sensor module 15, which integrates various sensors. The sensor module 15 is connected to the power transmission link on the rotating mounting ring 6 via wires to obtain power and transmit the detected motion parameters of the rotating mounting ring 6 to the processing unit. A ring-shaped limiting rotation sleeve 26 is also fixedly installed at the bottom of the top mounting plate 8. The limiting rotation sleeve 26 is coaxially arranged with the limiting rotation groove 25. A limiting rotation slider 16 is movably embedded inside the limiting rotation sleeve 26. The bottom of the limiting rotation slider 16 is fixedly connected to the top of the rotating mounting ring 6 and rotates synchronously with the rotating mounting ring 6. The outer side wall of the limiting rotation slider 16 slides against the inner side wall of the limiting rotation sleeve 26, forming a double limiting structure with the limiting rotation column 14 and the limiting rotation groove 25, further limiting the radial displacement of the rotating mounting ring 6 and ensuring rotational stability.

[0041] like Figure 9 As shown, the inner wall of the rotating mounting ring 6 has an annular limiting guide groove 33, and the side wall of the limiting guide groove 33 is fixedly provided with a power supply slide rail 34. The power supply slide rail 34 is connected to the power transmission link on the rotating mounting ring 6 through a wire, forming an intermediate node for the second stage of power transmission. The two sets of adjustment mechanisms of the adjusting clamping component are symmetrically distributed inside the rotating mounting ring 6. The core of the adjustment mechanism is the limiting guide block 40, which is movably embedded in the limiting guide groove 33. Its side wall has a power supply slide groove 50, which slides and engages with the power supply slide rail 34. The inner wall of the power supply slide groove 50 is provided with a conductive sheet, which is in close contact with the power supply slide rail 34.

[0042] When the limiting guide block 40 slides along the limiting guide groove 33, the conductive sheet remains in contact with the power supply slide rail 34, ensuring continuous power transmission to the limiting guide block 40. A rotary drive component 37 is fixedly mounted on the side of the limiting guide block 40 near the adjusting mounting ring 7 of the adjusting clamping component. The rotary drive component 37 is connected to the conductive sheet on the limiting guide block 40 via a wire to obtain power. The output end of the rotary drive component 37 is fixedly connected to the outer wall of the adjusting mounting ring 7. After being energized, it can drive the adjusting mounting ring 7 to rotate around the line connecting the two sets of adjusting mechanisms, thereby adjusting the angle of the adjusting mounting ring 7.

[0043] The inner wall of the rotating mounting ring 6 is also fixedly provided with an annular displacement ring 35, which is coaxially arranged with the limiting guide groove 33. Two rotating wheel frames 38 are also fixedly provided on the limiting guide block 40. The two rotating wheel frames 38 are symmetrically distributed about the rotating drive component 37. A displacement drive wheel 39 is rotatably mounted at the end of each rotating wheel frame 38. The outer circumferential surface of the displacement drive wheel 39 is in close contact with the displacement ring 35. The displacement drive wheel 39 is driven by a micro motor. The micro motor is connected to the power link on the limiting guide block 40 through a wire. After being energized, it can drive the limiting guide block 40 to slide along the limiting guide groove 33, thereby driving the adjusting mounting ring 7 to move along the inner wall of the rotating mounting ring 6, so as to realize the position adjustment of the adjusting mounting ring 7.

[0044] like Figure 10 As shown, the inner wall of the adjusting mounting ring 7 has an annular displacement guide groove 27, and a conductive slide rail 28 is fixedly mounted on the side wall of the displacement guide groove 27. The conductive slide rail 28 is connected to the power transmission link on the adjusting mounting ring 7 via a wire. This link extends from the limiting guide block 40 via a wire, forming a node for the third-stage power transmission. Several displacement guide blocks 29 are movably embedded in the displacement guide groove 27. Each displacement guide block 29 has a conductive groove 41 on its side wall. The conductive groove 41 is slidably fitted with the conductive slide rail 28, and the inner wall of the conductive groove 41 is provided with conductive contacts that are in close contact with the conductive slide rail 28.

[0045] When the displacement guide block 29 slides along the displacement guide groove 27, the conductive contacts are always in contact with the conductive slide rail 28, ensuring continuous power transmission to the displacement guide block 29. Each displacement guide block 29 has a floating wheel frame 30 fixedly mounted on both sides. An elastic element 31 is fixedly connected between the floating wheel frame 30 and the displacement mounting plate 12, providing cushioning. Several movable drive wheels 32 are rotatably mounted on the floating wheel frame 30. The outer circumferential surface of the movable drive wheels 32 is tightly fitted against the inner wall of the adjusting mounting ring 7. The movable drive wheels 32 are driven by a micro motor, which is connected to the power link on the displacement guide block 29 via a wire. After being energized, the micro motor can drive the displacement guide block 29 to slide along the displacement guide groove 27, adjusting the position of the displacement guide block 29.

[0046] Each displacement guide block 29 is fixedly equipped with a displacement mounting plate 12, and a clamping mechanism is fixedly installed on the displacement mounting plate 12. The number of clamping mechanisms is the same as that of the displacement mounting plates 12, and they correspond one-to-one. The core of the clamping mechanism is a cross mounting post 13, which is fixed on the corresponding displacement mounting plate 12. One electric telescopic rod 42 and two guide telescopic rods 43 are fixedly installed on the cross mounting post 13. The two guide telescopic rods 43 are symmetrically distributed on both sides of the electric telescopic rod 42. The telescopic ends of the electric telescopic rod 42 and the guide telescopic rods 43 are fixedly connected to the telescopic mounting plate 44.

[0047] like Figure 11As shown, the electric telescopic rod 42 is connected to the power link on the displacement guide block 29 via a wire. After being energized, it can drive the telescopic mounting plate 44 to move along the direction of the guide telescopic rod 43, which serves to guide and prevent deviation. A steering drive component 51 is fixedly installed on the side of the telescopic mounting plate 44 away from the cross mounting post 13. The steering drive component 51 is connected to the power link via a wire, and its output end is fixedly connected to the steering mounting frame 45. After being energized, it can drive the steering mounting frame 45 to rotate, adjusting the angle of the steering mounting frame 45.

[0048] Two symmetrically arranged swing telescopic rods 46 are movably mounted on the steering mounting bracket 45. The cylinders of the swing telescopic rods 46 are rotatably connected to the steering mounting bracket 45 via a drive shaft. The telescopic end of the swing telescopic rod 46 is fixedly connected to one end of an elastic connecting block 47, and a clamping plate 48 is fixedly mounted on the other end of the elastic connecting block 47. The clamping plates 48 on the two swing telescopic rods 46 are arranged opposite to each other. The swing telescopic rods 46 are connected to a power link via wires, and can extend and retract themselves after being energized. A micro motor is installed at the shaft of the swing telescopic rod 46, which can control the rotation angle of the swing telescopic rod 46, thereby adjusting the spacing and angle of the clamping plates 48 to adapt to steel structures of different sizes and shapes. The opposing surfaces of the clamping plates 48 are provided with anti-slip horizontal grooves 49, which can enhance the friction with the steel structure and ensure stable clamping. The elastic connecting block 47 can provide cushioning during clamping to avoid damage to the surface of the steel structure.

[0049] Working process: First, the entire device is fixed on the detection platform by the fixing strip 18 on the side wall of the support base 2 and the fixing plate 19 on the side wall of the balance mounting seat 1. The rubber ring 9 at the bottom of the balance mounting seat 1 and the support base 2 are in contact to ensure the stability of the device. The processing unit on the back of the display 20 is started by operating the keyboard 21 or touch panel 22 on the balance mounting seat 1. The detection parameters such as rotation speed and sampling frequency of sensor module 15 are set on the display 20. At this time, the power is transmitted through the wires inside the balance mounting seat 1 to the power supply ring 5 on the inner side wall of the support rotating sleeve 17, and then through the rotating brush 36 on the support rotating slider 11 to the rotating mounting ring 6 and each electrical component, thus completing the power supply for the entire device.

[0050] Based on the size and shape of the steel structure to be tested, adjust the position of the displacement guide block 29 on the inner wall of the adjusting mounting ring 7: start the micro motor of the moving drive wheel 32 to drive the displacement guide block 29 to slide along the displacement guide groove 27 until the distribution positions of multiple displacement mounting plates 12 are adapted to the steel structure clamping requirements; during the movement, the conductive slide groove 41 on the side wall of the displacement guide block 29 always slides in contact with the conductive slide rail 28 in the displacement guide groove 27 to ensure a continuous power supply. Then adjust the clamping mechanism: start the electric telescopic rod 42 to drive the telescopic mounting plate 44 to move along the direction of the guide telescopic rod 43, so that the clamping plate 48 is close to the surface of the steel structure; start the steering drive component 51 to adjust the angle of the steering mounting frame 45, and then through the extension and swing of the swing telescopic rod 46, let the two opposing clamping plates 48 fit against the outer wall of the steel structure. The anti-slip horizontal stripes 49 on the clamping plate 48 enhance the friction, and the elastic connecting block 47 buffers the clamping force to avoid damage to the steel structure, and finally achieves stable clamping of the steel structure.

[0051] The main drive unit 10 on the support base 2 is activated, driving the rotating mounting ring 6 to rotate around its own vertical axis. Simultaneously, the adjusting mounting ring 7 and the clamped steel structure rotate synchronously. During rotation, the support rotating slider 11 slides within the support rotating sleeve 17, the limiting rotating slider 16 slides within the limiting rotating sleeve 26, and the limiting rotating column 14 rotates along the limiting rotating groove 25. This triple coordination restricts the offset of the rotating mounting ring 6. The steady-state cavity 24 within the top mounting plate 8 absorbs vibration, ensuring smooth rotation. The sensor module 15 on the limiting rotating column 14 collects the motion parameters of the rotating mounting ring 6, such as displacement and acceleration, in real time and transmits them to the processing unit. The data is displayed in real time on the display 20. If the parameters show a center of gravity offset, adjust as follows: First, start the micro motor of the displacement drive wheel 39 to drive the limit guide block 40 to slide along the limit guide groove 33, changing the circumferential position of the adjustment mounting ring 7 within the rotating mounting ring 6; then start the rotary drive component 37 to drive the adjustment mounting ring 7 to rotate around the line connecting the two sets of adjustment mechanisms, adjusting the tilt angle of the adjustment mounting ring 7; finally, simultaneously fine-tune the position of the displacement guide block 29 and the distance between the clamping mechanism until the parameters of the sensor module 15 tend to stabilize, indicating that the overall center of gravity of the device and the steel structure is centered, at which point stop the main drive component 10.

[0052] Keeping the positions of the adjusting mounting ring 7, the displacement guide block 29, and the clamping mechanism unchanged, remove the clamped steel structure. Restart the main drive unit 10 to make the rotating mounting ring 6, the adjusting mounting ring 7, and each adjusting component rotate according to the original parameters. The sensor module 15 re-collects motion parameters, and the processing unit calculates the balance center position of only the device's own adjusting components under the current no-load state based on the parameters. This position is clearly displayed on the display 20.

[0053] Based on the principle of center of gravity balance, the center of gravity detected under no-load conditions is in the opposite position in three-dimensional space to the center of gravity centered during the previous clamping of the steel structure. The processing unit automatically calculates the symmetrical opposite position coordinates in three-dimensional space, which is the center of gravity of the steel structure to be tested. The final center of gravity parameters can be viewed on the display 20, or the data can be exported through an external device connected to the expansion interface 23, completing the entire steel structure center of gravity detection process.

[0054] As can be seen from the above embodiments, the beneficial effects of this application are as follows: 1. It can flexibly adapt to irregular steel structures. Through the multi-dimensional adjustable mounting ring and movable clamping mechanism, it can achieve stable clamping and center of gravity adjustment to meet different testing needs.

[0055] 2. Strong operational stability: Multiple limiting structures, symmetrically distributed support and drive components, combined with the vibration reduction effect of the steady-state cavity, reduce equipment shaking and detection errors, and ensure detection accuracy.

[0056] 3. Convenient operation and power supply: The continuous sliding power supply design avoids wire problems. The display, input and expansion components of the control mechanism facilitate parameter adjustment and data processing, improving ease of use.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application.
