Specific embodiments

[0023] To better understand the above technical solutions, the technical solutions of the embodiments of the present application will be described in detail below with reference to the drawings and specific embodiments. It should be understood that the specific features in the embodiments of the present application and the embodiments are detailed descriptions of the technical solutions of the embodiments of the present application, rather than limitations on the technical solutions of the present application. Without conflict, the technical features in the embodiments of the present application and the embodiments can be combined with each other.

[0024] An embodiment of the present application provides a hanger performance detection device 10, as Figure 1 , Figure 2 and Figure 3 shown. The hanger 20 includes a cross beam 21, a suspender 22 and a suspended member 23. The top end of the suspender 22 passes through the cross beam 21 and is clamped with the cross beam 21. The bottom end of the suspender 22 is connected to the suspended member 23. The hanger performance detection device 10 includes: a detection shaft 100, a driving assembly 200 and a stress sensor 300. The bottom end of the detection shaft 100 is used to connect the top end of the suspender 22. The driving assembly 200 is connected to the top end of the detection shaft 100. The driving assembly 200 is used to drive the detection shaft 100 to move axially. The stress sensor 300 is arranged on the detection shaft 100.

[0025] In this embodiment, the hanger 20 is an industrial load component. For example, a constant force hanger for a gasifier or a hanger 20 for a pressure vessel. The two ends of the suspender 22 are respectively connected to the cross beam 21 and the suspended member 23, so that the suspended member 23 is suspended below the cross beam 21. The suspender 22 is clamped with the top surface of the cross beam 21 to achieve limit, so that the suspender 22 can be lifted upward relative to the cross beam 21 and prevent the suspender 22 from falling below the cross beam 21.

[0026] The top end of the suspender 22 passes through the cross beam 21 and is connected to the bottom end of the detection shaft 100. The detection shaft 100 is located above the suspender 22 and is coaxially arranged with the suspender 22. The driving assembly 200 provides structural support for the top end of the detection shaft 100. Figure 1In this, X is the axial direction of the detection shaft 100. The driving assembly 200 can drive the detection shaft 100 to move up and down axially, thereby driving the suspension rod 22 to move up and down axially. The detection shaft 100 directly bears the load of the suspension rod 22. A stress sensor 300 is provided on the detection shaft 100. The stress sensor 300 is used to detect the stress on the detection shaft 100, and thereby obtain the force condition of the suspension rod 22.

[0027] It can be understood that the operator can regularly detect the hanger 20 through the hanger performance detection device 10, or the hanger performance detection device 10 is installed on the hanger 20 to perform long-term monitoring on the operation of the hanger 20.

[0028] Through the detection shaft 100, the performance of the hanger 20 can be directly fed back, ensuring the accuracy and reliability of the detection data. Moreover, the detection structure is simplified, and the portability of the detection device and the convenience of the detection operation are improved. Through the stress sensor 300, the changes in the load and stress parameters of the hanger 20 during the working process can be monitored in real time, providing data support for the safe use and regular maintenance of the hanger 20, making the monitoring results more accurate, improving the service life and safety of the equipment, and reducing the potential safety hazards of the hanger 20 during operation.

[0029] In some embodiments provided by the present application, such as Figure 1 、 Figure 2 and Figure 3 As shown, the hanger performance detection device 10 further includes: a cover plate 400. The cover plate 400 is provided at the top end of the detection shaft 100. The cover plate 400 extends along the radial direction of the detection shaft 100. The driving end of the driving assembly 200 abuts against the bottom surface of the cover plate 400.

[0030] In this embodiment, the top end of the detection shaft 100 passes through the center of the cover plate 400 and is connected to the cover plate 400. The driving assembly 200 is located below the cover plate 400. The driving end of the driving assembly 200 can move upward, thereby jacking up the detection shaft 100 upward through the cover plate 400, enabling the detection shaft 100 to bear the load of the suspension rod 22, and thereby obtaining the force condition of the suspension rod 22. Figure 1 In this, Y is the radial direction of the detection shaft 100. Since the cover plate 400 extends radially outward along the detection shaft 100, the cover plate 400 expands the contact area of the driving end, facilitating the driving assembly 200 to apply a driving force, enabling the driving assembly 200 to more easily drive the detection shaft 100 to lift the suspension rod 22 upward, and improving the driving efficiency and driving convenience.

[0031] In some embodiments provided by the present application, such as Figure 2 and Figure 3As shown in the figure, the driving assembly 200 includes: a hydraulic cylinder 210, a piston 220, and a hydraulic pump 230. The top end of the piston 220 is connected to the detection shaft 100. The bottom end of the piston 220 is located inside the hydraulic cylinder 210 and is slidably connected to the hydraulic cylinder 210. The piston 220 divides the hydraulic cylinder 210 into a first chamber 212 and a second chamber 213. The hydraulic pump 230 is respectively communicated with the first chamber 212 and the second chamber 213.

[0032] In this embodiment, the driving assembly 200 is a hydraulic assembly. The top end of the piston 220 extends out of the hydraulic cylinder 210 to form the driving end of the driving assembly 200. Specifically, the piston 220 abuts against the bottom surface of the cover plate 400 to connect the detection shaft 100 through the cover plate 400, so as to be able to lift the cover plate 400 and the detection shaft 100 upward. The bottom end of the piston 220 divides the hydraulic cylinder 210 into the mutually isolated first chamber 212 and second chamber 213. The first chamber 212 is above the second chamber 213. By changing the volumes of the first chamber 212 and the second chamber 213, the piston 220 can be driven to slide up and down along the inner wall of the hydraulic cylinder 210.

[0033] The hydraulic pump 230 is used to provide power hydraulic oil. When the hydraulic pump 230 inputs hydraulic oil into the second chamber 213, the volume of the second chamber 213 gradually increases, the piston 220 moves upward, and the detection shaft 100 drives the hanging rod 22 to lift upward. As Figure 3 shown, the hanging rod 22 is lifted by a distance A. When the hydraulic pump 230 inputs hydraulic oil into the first chamber 212, the volume of the first chamber 212 gradually increases, the piston 220 moves downward, and the detection shaft 100 drives the hanging rod 22 to descend. By controlling the driving speed and driving object of the hydraulic pump 230, the movement direction, movement speed, and displacement of the detection shaft 100 can be controlled, and further the operating state of the hanging rod 22 can be accurately controlled, improving the convenience and accuracy of detection.

[0034] In some embodiments provided by the present application, as Figure 2 shown, the hydraulic cylinder 210 is provided with a central hole 211. The central hole 211 penetrates through both sides of the hydraulic cylinder 210, and the detection shaft 100 passes through the central hole 211.

[0035] In this embodiment, the central hole 211 of the hydraulic cylinder 210 penetrates through the top surface and the bottom surface of the hydraulic cylinder 210 in the height direction, making the hydraulic cylinder 210 form an annular hollow structure. The hydraulic cylinder 210 surrounds the outer periphery of the detection shaft 100 and applies a driving force to the detection shaft 100 in the circumferential direction, making the driving position of the driving assembly 200 more uniform, and further making the stress state and movement state of the detection shaft 100 more stable. Specifically, the top end of the hanging rod 22 extends into the central hole 211 and is connected to the bottom end of the detection shaft 100 to save the occupied space of the detection operation.

[0036] Exemplarily, the piston 220 includes a connected bottom plate and a top portion, the bottom plate is slidably connected to the inner wall of the hydraulic cylinder 210, and the top portion abuts against the cover plate 400. Specifically, the top portion is an annular cylinder structure and surrounds the outer periphery of the center hole 211. Alternatively, the top portion is a rod-shaped structure, and a plurality of top portions are circumferentially spaced and arranged on the outer periphery of the center hole 211.

[0037] In some embodiments provided in this application, Figure 2 As shown, the driving assembly 200 further includes: a control valve 240 , which is disposed between the hydraulic pump 230 and the hydraulic cylinder 210 , and is used to control the input flow of the hydraulic cylinder 210 .

[0038] In this embodiment, the hydraulic pump 230 is connected to the hydraulic cylinder 210 through an oil pipeline. After the hydraulic pump 230 is started, the hydraulic oil is transported to the hydraulic cylinder 210 through the oil pipeline. A control valve 240 is provided on the oil pipeline. The control valve 240 is a flow control valve 240. The control valve 240 controls the flow and pressure of the hydraulic oil in the oil pipeline, controls the input flow of the hydraulic cylinder 210, ensures that the hydraulic cylinder 210 can stably provide power for the detection shaft 100, and then accurately controls the operating state and movement position of the boom 22, thereby improving the convenience and accuracy of detection.

[0039] In some embodiments provided in this application, Figure 2 and Figure 3 As shown, the hanger performance detection device 10 further includes: a pad 500, and two sides of the pad 500 are respectively connected to the driving assembly 200 and the crossbeam 21.

[0040] In this embodiment, a pad 500 is placed on the top surface of the cross beam 21, and part of the drive assembly 200 is placed on the pad 500. Specifically, the pad 500 supports the hydraulic cylinder 210. The pad 500 forms a spacing between the drive assembly 200 and the cross beam 21, and the spacing forms an escape space for the lifting of the boom 22, so as to prevent the parts arranged on the boom 22 from colliding with the drive assembly 200 during the lifting process of the boom 22. Exemplarily, the boom 22 is provided with a clamping portion clamped with the top surface of the cross beam 21, and the pad 500 can prevent the clamping portion from colliding with the drive assembly 200. In addition, the pad 500 improves the stability of the drive assembly 200, and prevents the drive assembly 200 from colliding with the cross beam 21. The driving assembly 200 is placed on the beam 21 through the pad 500, so that the driving assembly 200 can provide structural support with the help of the beam 21, avoiding the additional setting of support components, improving the lightness of the hanger performance detection device 10, and improving the flexibility and convenience of detection.

[0041] Exemplarily, the backing plate 500 extends radially outwards from the hydraulic cylinder 210 to improve the smoothness of support. The number of the backing plates 500 is multiple, and the number of the backing plates 500 is adjusted according to different models of the hanging bracket 20 to control the lifting height of the backing plate 500, and further control the lifting space of the suspension rod 22.

[0042] In some embodiments provided by the present application, such as Figure 2 and Figure 3 shown, the hanging bracket performance detection device 10 further includes: a connecting cylinder 600, and the ends of the detection shaft 100 and the suspension rod 22 can respectively extend into the connecting cylinder 600 from both sides and are threadedly connected to the connecting cylinder 600.

[0043] In this embodiment, the connecting cylinder 600 is located in the central hole 211. Internal threads are provided at both ends of the connecting cylinder 600, and external threads are provided at the bottom end of the detection shaft 100 and the top end of the suspension rod 22. After the suspension rod 22 and the detection shaft 100 respectively extend into the connecting cylinder 600 from both sides, they are threadedly connected, so that the suspension rod 22 and the detection shaft 100 are coaxially connected, ensuring the stability of the connection and improving the reliability of the detection process.

[0044] In some embodiments provided by the present application, such as Figure 2 and Figure 3 shown, the suspension rod 22 includes a top rod 221 and a bottom rod 222 that are flexibly connected. The hanging bracket performance detection device 10 further includes: a displacement sensor 700, and the displacement sensor 700 is used to connect the top rod 221 and the bottom rod 222 to detect the displacement between the top rod 221 and the bottom rod 222.

[0045] In this embodiment, the bottom rod 222 is snap-connected to the hanging member 23, the top rod 221 is connected to the detection shaft 100, and an elastic member 224 is provided between the bottom rod 222 and the top rod 221. Exemplarily, the elastic member 224 can be a spring. The two ends of the elastic member 224 are respectively connected to the bottom rod 222 and the top rod 221, so that the bottom rod 222 and the top rod 221 are flexibly connected. The top of the bottom rod 222 is covered with an installation cylinder 223, and the installation cylinder 223 covers the outside of the elastic member 224 and a part of the bottom of the top rod 221. When the detection shaft 100 moves upward, the top rod 221 is lifted upward and pulls the elastic member 224 to elongate. The elastic deformation generated by the elastic member 224 absorbs the driving force, so that the bottom rod 222 and the hanging member 23 stay in place, and thus the top rod 221 generates a displacement relative to the bottom rod 222. The two ends of the displacement sensor 700 are respectively connected to the top rod 221 and the bottom rod 222. Specifically, the displacement sensor 700 is connected to the installation cylinder 223 at the top of the bottom rod 222. When the hanging rod 22 is in the lifted state, the displacement sensor 700 can detect the displacement between the top rod 221 and the bottom rod 222. By monitoring the minute displacement changes of the equipment during operation or detection through the high-precision displacement sensor 700, the displacement condition of the hanging bracket 20 is obtained, providing data support for the safe use and regular maintenance of the hanging bracket 20 and making the monitoring results more accurate.

[0046] In some embodiments provided by the present application, the displacement sensor 700 can connect the top rod 221 and the bottom rod 222 through magnetic suction force.

[0047] In this embodiment, the connecting part of the displacement sensor 700 is a magnetic part. The connecting part connects the top rod 221 and the bottom rod 222 through magnetic suction force, enabling a detachable connection between the displacement sensor 700 and the hanging rod 22. Moreover, the operator can more conveniently and quickly set the displacement sensor 700 on the hanging rod 22, effectively improving the convenience of installation and disassembly of the displacement sensor 700.

[0048] In some embodiments provided by the present application, such as Figure 2 and Figure 4 shown, the hanging bracket performance detection device 10 further includes: a control device 800, which is used to control the movement of the driving assembly 200 and receive and store the data collected by the stress sensor 300 and the displacement sensor 700.

[0049] In this embodiment, the stress sensor 300, the displacement sensor 700, and the driving assembly 200 are respectively communicatively connected to the control device 800. The control device 800 can control the lifting and lowering heights of the detection shaft 100, so that the data measured by the stress sensor 300 and the displacement sensor 700 can be transmitted into the control device 800. The control device 800 performs real-time analysis and processing on the changes in the collected displacement and stress parameters through a preset algorithm, and determines whether the working state of the device is normal. Additionally, when it is confirmed that the working state is abnormal, an alarm signal is issued to remind the operator to take corresponding safety measures, thereby ensuring the safe operation of the device and extending its service life.

[0050] Exemplarily, the control device 800 can be a functional module and / or a functional entity. The control device includes: a processor and a memory. The memory stores programs or instructions that can run on the processor. When the programs or instructions are executed by the processor, the steps of the control method of the hanger performance detection device 10 are implemented. The control device 800 can simulate the stress state of the hanger 20 under different working conditions, so that the hanger performance detection device 10 operates according to a predetermined test procedure. For example, when testing the constant force hanger of the gasifier, first, the hanger 20 is lifted by 50 mm and held for 5 min. During this process, the driving assembly 200 provides a stable lifting force, and the control device 800 records the displacement and load data during the lifting process. Then, the hanger 20 is lowered by 45 mm and held for 5 min, then lifted by 45 mm and held for 5 min, and finally lowered by 50 mm. During the whole process, the driving assembly 200 ensures the smooth execution of each action, making the test data accurate and reliable.

[0051] In a specific embodiment, taking the constant force support hanger 20 as an example, the top load support cover plate 400 is installed at the corresponding position of the hanger 20 for transmitting and dispersing the load during the operation of the device. The stress test detection shaft 100 is tightly connected to the cover plate 400. A high-precision stress sensor 300 is installed inside the detection shaft 100, which can directly sense the load generated during the operation of the device and transmit the stress data to the software system of the control device 800 in real time.

[0052] Exemplarily, the software system is installed on the processor of the control device 800. After running the test system program, it is first necessary to set the test parameters and safety thresholds. For different hanger 20 devices, corresponding parameters are set according to their design specifications and operating requirements. Then, the device is precisely lifted to a predetermined height by the power system and maintained for a certain period of time. During this period, the test system accurately collects data. Subsequently, multiple lifting and lowering operations are repeated, and the test data during different operation processes are comprehensively recorded. Finally, the data is transmitted to the software system for in-depth analysis. Based on the analysis results, it is accurately judged whether the working state of the device is safe, thereby ensuring the reliable operation and timely maintenance of the device. When the test data exceeds the preset safety threshold, the alarm mechanism is immediately automatically triggered to remind the operator to adjust or replace the device in a timely manner. At the same time, the software system also has a data export function, which is convenient for the operator to further analyze the data, understand the performance change trend of the device, and generate detailed reports for device management and maintenance decisions.

[0053] The hanger performance detection device 10 can be appropriately adjusted and optimized according to the specific characteristics and test requirements of different industrial devices, ensuring that this portable industrial equipment load testing device can effectively play its role and provide a strong guarantee for the safe and stable operation of industrial equipment.
