[0001] The present invention relates to the field of performance detection of metal hoses, and particularly to a metal hose swing test device. Background Art

[0002] As a key connecting component for special fields, the performance of metal hoses directly affects the reliability and service life of application systems. In actual working conditions, metal hoses often need to withstand swinging actions in multiple directions, which may cause structural fatigue, damage or even failure of the hoses. Therefore, before the metal hose products leave the factory, it is necessary to sample and conduct swing test detection on the batch products, and it is required to fully simulate the actual working conditions to accurately evaluate their performance under complex dynamic loads. The test needs to reproduce the actual working conditions, specifically including adjusting parameters such as installation position, torque, swing frequency, swing angle, internal pressure, etc. And usually, a variety of fixtures need to be designed or adjusted for test pieces of different specifications.

[0003] Currently, many of the existing publicly disclosed metal hose swing test schemes have single functions and limited adjustment capabilities, and are not suitable for metal hoses used in special fields. The invention patents with application numbers CN200710159151.1 (Metal Hose Bending and Swinging Testing Machine) and CN201410692212.0 (Swing Fatigue Test Device), although the disclosed test schemes can achieve the swing test of metal hoses, they cannot adjust parameters such as the installation positions of the upper and lower joints of the metal hose and the position of the lower joint relative to the swing center, and it is difficult to comprehensively simulate the complex dynamic working conditions in actual use.

[0004] Therefore, there is an urgent need for a metal hose swing test device. Summary of the Invention

[0005] In view of the above-mentioned drawbacks and deficiencies of the prior art, the present invention provides a metal hose swing test device, which solves the technical problems that the existing metal hose swing test device has a single swing test shape, can only achieve the swing test in the bending state, and cannot adjust the installation positions of the upper and lower joints of the metal hose and parameters such as the position of the joint relative to the swing center.

[0006] In order to achieve the above object, the main technical solutions adopted by the present invention include: An embodiment of the present invention provides a metal hose swing test device.

[0007] A metal hose swing test device proposed by an embodiment of the present invention includes: A first fixed seat; A fixing component; A power swing component, connected to the first fixed seat, for moving the first fixed seat relative to the fixing component; The test hose has one end detachably mounted on the plane of the first fixed seat and the other end detachably mounted on the plane of the fixing assembly; Wherein, the axes of the two ends of the test hose do not coincide, so that the test hose is in a bent state between the first fixed seat and the fixing assembly.

[0008] Optionally, the metal hose swing test device further includes: A support frame, on which the fixing assembly and the power swing assembly are both arranged.

[0009] Optionally, the fixing assembly includes: A second fixed seat, which is arranged parallel to the first fixed seat and is arranged on the support frame, and the other end of the test hose is detachably mounted on the end face of the second fixed seat.

[0010] Optionally, the fixing assembly further includes: A third fixed seat, which is arranged perpendicular to the first fixed seat and is slidably mounted on the support frame, and the other end of the test hose is detachably mounted on the end face of the third fixed seat.

[0011] Optionally, the power swing assembly includes: A swing member, one end of which is rotatably mounted on the support frame, and the first fixed seat is detachably mounted on the swing member; A driving component, the output end of the driving component is connected to the swing member, and is used to make the swing member swing relative to the support frame.

[0012] Optionally, the metal hose swing test device further includes: A lifting assembly, which is arranged on the support frame and is connected to the second fixed seat, and is used to move in a direction close to or away from the first fixed seat.

[0013] Optionally, the lifting assembly includes: A lead screw, which is rotatably mounted on the support frame, the second fixed seat is slidably mounted on the support frame along the axis of the lead screw and is threadedly connected to the lead screw; An adjustment handwheel, which is connected to the lead screw and is used to drive the lead screw to rotate along its axis.

[0014] Optionally, the swing member includes: A load substrate, on the surface of which first mounting holes are formed at equal intervals, and the first fixed seat is detachably mounted on the first mounting holes; A swing rod, which is arranged between the load substrate and the support frame, and an operation hole is formed through the swing rod, and the driving component is connected to the operation hole.

[0015] Optionally, the metal hose swing test device further includes: A pressure control system is arranged between the driving component and the test hose and is used to control the driving component to stop working when the pressure in the test hose is lower than a preset pressure value.

Among them, the two ends of the test hose are respectively detachably installed on the planes of the first fixed seat and the fixing component, and the axes of the two ends of the test hose do not coincide. After installation, the test hose naturally presents a bent state and is located between the first fixed seat and the fixing component. Through this setting of the bent state, the limitation that the traditional test device can only test the metal hose in a single bending state is broken. The bent posture can make the test closer to the actual installation and use conditions of the metal hose in some complex industrial pipeline systems or special application scenarios, and can fully simulate the stress and movement states of the metal hose at different angles and bending conditions, so that the swinging test can more comprehensively evaluate the performance of the metal hose.

Therefore, a more comprehensive, flexible and actual-use-situation-close test environment is provided for the metal hose, so that the test results can more accurately reflect the performance of the metal hose under various complex working conditions, and more effective data support is provided for the quality evaluation and R & D improvement of the product.

Detailed implementation manner

[0020] For better explaining the present invention for easy understanding, the present invention will be described in detail below in conjunction with the accompanying drawings through specific implementation manners. Among them, the orientation nouns such as "upper" and "lower" mentioned in this article are Figure 1 oriented as a reference.

[0021] To better understand the above technical solutions, the exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to convey the scope of the present invention completely to those skilled in the art.

[0022] As Figures 1 to 3 shown, according to an embodiment of the present application, a metal hose swing test device is proposed, including: a first fixing base 100; a fixing component 200; a power swing component 300, connected to the first fixing base 100 above, for moving the first fixing base 100 relative to the fixing component 200 above; a test hose 400, one end of which is detachably installed on the plane of the first fixing base 100, and the other end is detachably installed on the plane of the fixing component 200 above; wherein, the axes of both ends of the test hose 400 do not coincide, so that the test hose 400 is in a bent state between the first fixing base 100 and the fixing component 200 above.

[0023] The metal hose sway test device provided by the embodiment of the present application includes a first fixed seat 100, a fixing component 200, a power sway component 300, and a test hose 400. Among them, the first fixed seat 100 provides a detachable mounting plane for one end of the test hose 400, and the fixing component 200 provides a detachable mounting plane for the other end of the test hose 400. Together with the first fixed seat 100, the two ends of the test hose 400 can be firmly fixed in the device, providing a mounting basis for the test hose 400. The power sway component 300 is connected to the first fixed seat 100, providing power for the test device, enabling the first fixed seat 100 to move relative to the fixing component 200. Through relative movement, the sway movement that may occur in the actual use environment of the metal hose can be simulated. At the same time, the driving method and control mechanism of the power sway component 300 can precisely adjust parameters such as the movement mode, speed, and amplitude of the first fixed seat 100, further enriching the diversity and adjustability of the test. The two ends of the test hose 400 are respectively detachably mounted on the planes of the first fixed seat 100 and the fixing component 200. The axes of the two ends of the test hose 400 do not coincide, and the test hose 400 naturally presents a bent state after installation, being located between the first fixed seat 100 and the fixing component 200. Through this setting of the bent state, the limitation that the traditional test device can only test the metal hose in a single bent state is broken. The bent posture can make the test closer to the actual installation and use conditions of the metal hose in some complex industrial pipeline systems or special application scenarios, and can fully simulate the stress and movement states of the metal hose at different angles and bending conditions, enabling the sway test to more comprehensively evaluate the performance of the metal hose.

[0024] Through the coordinated work of the first fixed seat 100, the fixing component 200, and the power sway component 300, the problems existing in the prior art are effectively solved. Since the two ends of the test hose 400 are respectively detachably mounted on the relatively movable and adjustable first fixed seat 100 and fixing component 200, and there is an adjustable relative relationship between the two, it is very convenient to adjust important parameters such as the installation positions of the upper and lower joints of the test hose 400 and the position of the joint relative to the sway center position during the actual test process. Thus, a more comprehensive, flexible, and practical test environment is provided for the metal hose 400, making the test results more accurately reflect the performance of the metal hose under various complex working conditions, and providing more effective data support for the quality evaluation and R & D improvement of the product.

[0025] As Figure 1 and Figure 2 shown, in some instances, the metal hose sway test device further includes: a support frame 500, and both the fixing component 200 and the power sway component 300 are arranged on the above-mentioned support frame 500.

[0026] In this technical solution, the support frame 500 provides a stable installation foundation for the fixed component 200 and the power swing component 300. The solid structure of the support frame 500 can bear the weights of the fixed component 200 and the power swing component 300, preventing them from shaking, shifting or other unstable conditions due to their own weights or external forces during the test. This not only helps to maintain the stability of the test environment, thereby improving the accuracy of test data, but also ensures the safety of the device during operation, avoiding accidental damage or failures caused by the instability of components.

[0027] The fixed component 200 and the power swing component 300 are arranged on the support frame 500, which is beneficial to the reasonable layout and integration of the entire test device. The support frame 500 can determine the relative positional relationship between the fixed component 200 and the power swing component 300, enabling the components to cooperate more orderly. In addition to providing physical support and a layout framework, the support frame 500 can also play a protective role for the fixed component 200 and the power swing component 300 to a certain extent. It can serve as a protective barrier to prevent damage to the components caused by external debris and accidental collisions. During the operation of the device, the support frame 500 can reduce the direct interference of external factors on the fixed component 200 and the power swing component 300, extend their service lives, ensure the long-term stable and reliable operation of the equipment, and ensure that the metal hose swing test device can continuously and effectively carry out various tests, thereby providing a strong guarantee for accurately evaluating the performance of the metal hose.

[0028] As Figures 1 to 3 shown, in some instances, the above-mentioned fixed component 200 includes: a second fixed seat 210, which is arranged parallel to the above-mentioned first fixed seat 100 and is arranged on the above-mentioned support frame 500. The other end of the above-mentioned test hose 400 is detachably installed on the end face of the above-mentioned second fixed seat 210.

[0029] In this technical solution, the second fixed seat 210 is arranged on the support frame 500. The support frame 500 provides a stable structure for the entire device. Relying on this, the second fixed seat 210 ensures its own stability during the operation of the device. The second fixed seat 210 is arranged on the support frame 500. Through the stabilizing effect of the support frame 500, the second fixed seat 210 can resist various forces generated during the test, including the vibrations generated when the power swing component 300 works and the tensile forces brought by the swing of the test hose 400, etc., ensuring the stability of the test environment, thereby improving the accuracy and reliability of test data.

[0030] The second fixed seat 210 is arranged parallel to the first fixed seat 100. The installation positions at both ends of the test hose 400 have a parallel relationship on the basic plane. If the two fixed seats are not parallel, it may cause the test hose 400 to be distorted or in an abnormal stretching state after installation, thus affecting the authenticity of the test results. Secondly, the parallel arrangement provides an accurate reference and a stable track for the power swing assembly 300 to drive the first fixed seat 100 to move relative to the fixed assembly 200; when the first fixed seat 100 moves under the action of the power swing assembly 300, since the second fixed seat 210 is parallel and relatively fixed to it, the movement track of the first fixed seat 100 can be clearly defined, ensuring that the swing test action is more accurate and regular, and the simulated actual working conditions are more real.

[0031] The other end of the test hose 400 is detachably installed on the end face of the second fixed seat 210. The detachable installation method reflects the flexibility and versatility of the device. During the test process, according to different test requirements, different specifications and models of test hoses can be conveniently and quickly replaced to meet diverse test requirements. For example, when conducting swing tests on metal hoses with different pipe diameters, materials or different application scenarios, only need to install one end of the corresponding test hose 400 on the first fixed seat 100 and the other end on the end face of the second fixed seat 210 to start the test, without large-scale modification or adjustment of the device, greatly improving the use efficiency and application range of the device.

[0032] Exemplarily, a sliding table 800 is further included. The sliding table 800 is slidably installed on the second fixed seat 210. After adjusting the position, the sliding table 800 is fixed relative to the second fixed seat 210 by squeezing the sliding table 800 with a locking bolt, and the other end of the test hose 400 is installed on the sliding table 800 through a pressing plate 900. The port of the test hose 400 is in a boss shape. Through the squeezing fit between the pressing plate 900 and the sliding table 800, the port of the test hose 400 can be stably installed on the sliding table 800, thereby realizing the stable connection between the test hose 400 and the second fixed seat 210. Among them, the relative position of the test hose 400 relative to the second fixed seat 210 can be changed through the sliding table 800.

[0033] As Figures 1 to 3 shown, in some examples, the above-mentioned fixed assembly 200 further includes: a third fixed seat 220, which is arranged perpendicular to the above-mentioned first fixed seat 100 and is slidably installed on the above-mentioned support frame 500, and the other end of the above-mentioned test hose 400 is detachably installed on the end face of the above-mentioned third fixed seat 220.

[0034] In this technical solution, the third fixing seat 220 is arranged on the support frame 500, and the third fixing seat 220 can stably play its own role under the support of the support frame 500; the third fixing seat 220 is vertically arranged relative to the first fixing seat 100. This vertical arrangement greatly expands the dimensions and flexibility of the test. On the basis of the traditional test with only parallel fixing seats, the vertically arranged third fixing seat 220 enables the test hose 400 to form bending states at various spatial angles during installation. Compared with the single bending state in the past, it increases the simulation ability of the metal hose in different spatial postures and can better approximate the complex layout that the metal hose 400 may face in the actual use scenario.

[0035] By sliding on the support frame 500, the third fixing seat 220 can flexibly change its own position. As it slides, the installation position of the other end of the test hose 400 can be flexibly adjusted, thereby changing the parameters of the test hose 400 relative to the swing center position. The relative position and angular relationship of the joints at both ends of the test hose 400 can also be further precisely adjusted. This is crucial for simulating the actual working conditions of different installation conditions and can more comprehensively consider the physical properties such as stress and strain borne by the metal hose 400 in various situations, improving the comprehensiveness and accuracy of the test data.

[0036] The other end of the test hose 400 is detachably installed on the end face of the third fixing seat 220. This detachable installation design not only facilitates the replacement of different types and specifications of test hoses during the experiment and changes the position above the third fixing seat 220 to adapt to various test requirements, but also ensures the stability of the connection after installation, ensuring that both ends of the test hose 400 are fixed reliably during the test and avoiding inaccurate test results or equipment damage caused by loosening. Test hoses 400 with different pipe diameters, different materials, and different structures can be quickly installed on the third fixing seat 220 according to the experimental needs, realizing diversified test combinations and enhancing the versatility and applicability of the device.

[0037] In summary, the third fixing seat 220 is vertically arranged and slidably installed on the support frame 500, and the test hose 400 can be flexibly installed, significantly enhancing the test ability and flexibility of the metal hose swing test device, improving the adaptability of the test device to different test hoses 400 and complex simulation conditions, and more comprehensively and effectively evaluating the performance of the test hose 400 in various actual use environments.

[0038] Such as Figures 1 to 3As shown, in some examples, the above-mentioned power swing assembly 300 includes: a swing member 310, one end of which is rotatably mounted on the above-mentioned support frame 500, and the above-mentioned first fixing seat 100 is detachably mounted on the above-mentioned swing member 310; a driving component 320, the output end of the above-mentioned driving component 320 is connected to the above-mentioned swing member 310 for causing the above-mentioned swing member 310 to swing relative to the above-mentioned support frame 500; exemplarily, the driving component 320 can be selected but not limited to a telescopic motor.

[0039] In this technical solution, one end of the swing member 310 is rotatably mounted on the support frame 500, realizing that the swing member 310 can perform circular motion around the mounting point, which is the basic structure for realizing the swing function. By rotatably mounting on the support frame 500, the support frame 500 provides a stable fulcrum for the swing member 310, ensuring the stability and smoothness of the swing member 310 during subsequent movement, so that it can swing according to a predetermined trajectory under the action of the driving component.

[0040] The first fixing seat 100 is detachably mounted on the swing member 310. On the one hand, in the test preparation stage, different specifications or types of the first fixing seat 100 can be quickly replaced according to different test requirements to adapt to the installation requirements of different test hoses 400, greatly improving the test efficiency; on the other hand, according to different experimental requirements, the relative position of the first fixing seat 100 relative to the swing member 310 can be changed. Exemplarily, the swing member 310 can change its specific position on the swing member 310 along the height direction of the support frame 500; at the same time, during the equipment maintenance and inspection process, the first fixing seat 100 can be conveniently detached from the swing member 310 to perform separate maintenance and repair on each component, reducing the difficulty and cost of equipment maintenance. When the swing member 310 swings, it can drive the first fixing seat 100 detachably mounted on it to move synchronously, thereby realizing the swing drive of one end of the test hose 400.

[0041] The output end of the driving component 320 is connected to the swing member 310, enabling the driving component 320 to transmit its own generated power to the swing member 310 and drive the swing member 310 to swing relative to the support frame 500. Through this connection method, the power of the driving component 320 is converted into the mechanical motion of the swing member 310, thereby providing core power support for the entire swing test.

[0042] The main function of the driving component 320 is to make the swing member 310 swing relative to the support frame 500. It can control key parameters such as the swing amplitude, frequency and direction of the swing member 310 according to the parameters set in the test. For example, when simulating the use of the test hose 400 under different actual working conditions, the driving component 320 can accurately control the movement of the swing member 310 to achieve swing tests of the test hose 400 to different degrees and methods, thereby more accurately evaluating the performance of the test hose 400 in various actual scenarios; the telescopic motor can convert the telescopic action into a rotational swinging action of the swing member 310.

[0043] like Figures 1 to 3 As shown, in some examples, the metal hose swing test device further includes: a lifting assembly 600, which is disposed on the support frame 500 and connected to the second fixing seat 210, and is used to move toward or away from the first fixing seat 100.

[0044] In this technical solution, the lifting assembly 600 is arranged on the supporting frame 500. The lifting assembly 600 is installed relying on the supporting frame 500. It can remain stable during the operation of the device to avoid displacement or shaking due to vibration or other external force factors during the operation of the device, thereby ensuring the normal functioning of its functions.

[0045] The main function of the lifting assembly 600 is to enable the second fixing seat 210 to move toward or away from the first fixing seat 100. In the swing test of the metal hose, by changing the distance between the second fixing seat 210 and the first fixing seat 100, the initial tension or compression state of the test hose 400 during installation can be adjusted to simulate the difference in the distance and tension between the two ends of the metal hose connection in different actual use scenarios, so that the test is closer to the actual working conditions. For example, in actual applications, the distance between the installation points at both ends of the test hose 400 may vary. This adjustment function can accurately reproduce these situations and study the influence of different initial tension states on the swing performance of the test hose 400.

[0046] During the swing test, the distance between the two fixing seats can be flexibly changed according to the test needs, so as to further study the swing motion of the test hose 400 under different span conditions. For example, as the distance between the two fixing seats changes, the bending stress, fatigue and other conditions of the test hose 400 during the swinging process will be different, which is helpful to analyze the performance change law of the metal hose under different working conditions and improve the comprehensiveness and accuracy of the test results.

[0047] In summary, the lifting assembly 600 in the metal hose sway test device realizes precise adjustment of the position of the second fixed seat 210 through connection with the support frame 500 and the second fixed seat 210, enriches the simulated working conditions of the test, and improves the practicability of the test device and the reliability of the test results.

[0048] As Figures 1 to 3 shown, in some examples, the above-mentioned lifting assembly 600 includes: a lead screw 610 rotatably installed on the support frame 500, the second fixed seat 210 is slidably installed on the support frame 500 along the axis of the lead screw 610 and is threadedly connected to the lead screw 610; an adjustment handwheel 620 connected to the lead screw 610 for driving the lead screw 610 to rotate along its axis; there are at least four lead screws 610, and all four lead screws 610 are connected to the adjustment handwheel 620.

[0049] In this technical solution, the lead screw 610 is rotatably installed on the support frame 500, the second fixed seat 210 is slidably installed on the support frame 500 along the axis of the lead screw 610 and is threadedly connected to the lead screw 610. The rotational motion of the lead screw 610 can be converted into the linear motion of the second fixed seat 210. Due to the characteristic of the thread pair to transmit precise displacement, for every certain angle of rotation of the lead screw 610, the second fixed seat 210 will advance or retreat a certain precise distance along the axis direction of the lead screw 610, thereby realizing precise control of the position of the second fixed seat 210.

[0050] The connection between the adjustment handwheel 620 and the lead screw 610 enables the lead screw 610 to rotate along its own axis by rotating the adjustment handwheel 620. The adjustment handwheel 620 provides a convenient way for manual operation of the lifting assembly 600. The operator can adjust the position of the second fixed seat 210 by rotating the adjustment handwheel 620 as needed.

[0051] Exemplarily, at least four lead screws 610 can be provided, and all four lead screws 610 are connected to the adjustment handwheel 620. The arrangement of multiple lead screws 610 ensures the smoothness and uniformity of the movement of the second fixed seat 210. If only one lead screw 610 is used for transmission, when the second fixed seat 210 moves, especially when carrying a large weight or under a certain eccentric load, unstable phenomena such as tilting and jamming may occur. However, with the combined action of four lead screws 610, the load force can be evenly shared, ensuring that the second fixed seat 210 smoothly and steadily slides along the axis of the lead screw 610 on the support frame 500.

[0052] Exemplarily, the adjustment handwheel 620 and the lead screw 610 can be meshingly connected, and the transmission of force is realized through the meshing transmission between transmission gears.

[0053] The lead screw 610 is the core transmission component of the lifting assembly 600. It converts the rotational motion of the adjustment handwheel 620 into linear motion, providing power and precise displacement control for the movement of the second fixed seat 210. Through mechanical structure features, the lead screw 610 can convert a small rotational angle into a corresponding linear displacement of the second fixed seat 210, enabling the operator to precisely change the distance between the second fixed seat 210 and the first fixed seat 100 within a small adjustment range, so as to more accurately simulate the connection state and force conditions of the test hose 400 in different actual usage scenarios.

[0054] The adjustment handwheel 620 is the control input part of the entire lifting assembly 600. By manually rotating the adjustment handwheel 620, the operator can precisely control the rotation direction and speed of the lead screw 610, and thus determine the movement direction and displacement of the second fixed seat 210 along the axis of the lead screw 610, providing a convenient operation means for test adjustments under different specifications and application scenarios.

[0055] When the staff rotates the adjustment handwheel 620 according to the test requirements, the four lead screws 610 connected to the adjustment handwheel 620 start to rotate synchronously. Since there are thread pair connection relationships between the second fixed seat 210 and the four lead screws 610, as the lead screws 610 rotate, the second fixed seat 210 will smoothly move along the axis direction of the lead screws 610, and perform position adjustment in the direction of approaching or departing from the first fixed seat 100.

[0056] In summary, the lifting assembly 600 consists of a lead screw 610 and an adjustment handwheel 620, and the structural settings that cooperate with the lead screw 610 not only ensure that the second fixed seat 210 can move smoothly and precisely towards the first fixed seat 100, but also provide a simple and reliable adjustment device for the operator, which helps to improve the accuracy and applicability of the metal hose swing test, enabling the entire test device to better simulate diverse actual working environments and condition requirements.

[0057] As Figure 1 and Figure 3 shown, in some instances, the above-mentioned swing member 310 includes: a load substrate 311, on the surface of which first mounting holes 301 are formed at equal intervals, and the above-mentioned first fixed seat 100 is detachably mounted on the above-mentioned first mounting holes 301; a swing rod 312, arranged between the above-mentioned load substrate 311 and the above-mentioned support frame 500, and an operation hole 302 is formed through the above-mentioned swing rod 312, and the above-mentioned driving component 320 is connected to the above-mentioned operation hole 302.

[0058] In this technical solution, the load substrate 311 is formed with first mounting holes 301 at equal distances on its surface, providing multiple positioning options for the installation of the first fixing seat 100. According to the specifications of different test hoses 400 and test requirements, an appropriate installation position can be accurately selected, thereby improving the versatility and adaptability of the device.

[0059] The first fixing seat 100 is detachably installed on the first mounting hole 301. When conducting different swing tests on the test hose 400, according to the size, shape or other specific requirements of the hose, the specific position where the first fixing seat 100 is installed on the load substrate 311 can be changed, thereby changing the relative position with respect to the second fixing seat 210. During the movement of the swing member 310, the load substrate 311 bears the weight of the first fixing seat 100 and the test hose 400 and various forces generated during the test process, ensuring the stability and safety of the test components during the swing process.

[0060] The swing rod 312 is arranged between the load substrate 311 and the support frame 500, and it plays a role in connecting the two and transmitting motion. An operation hole 302 is formed through the swing rod 312, and this operation hole 302 is a key structure for connecting with the driving component 320. The driving component 320 is connected to the operation hole 302. Through this connection method, the power output by the driving component 320 can be accurately and effectively transmitted to the swing rod 312. When the driving component 320 works, it drives the swing rod 312 to swing around the installation point on the support frame 500. The swing of the swing rod 312 drives the load substrate 311 connected thereto and the first fixing seat 100 installed on the load substrate 311 to perform corresponding swing movements together, thereby realizing the swing test action of the test hose 400. The setting of the operation hole 302 not only ensures the stability of the connection between the driving component 320 and the swing rod 312, but also provides a reliable structural support for the accurate power transmission between the two, ensuring that the swing action can be carried out according to the predetermined manner and parameters to meet the test requirements.

[0061] As Figure 2 shown, in some instances, the metal hose swing test device further includes: a pressure control system 700, arranged between the above-mentioned driving component 320 and the above-mentioned test hose 400, and used to control the above-mentioned driving component 320 to stop working when the pressure in the above-mentioned test hose 400 is lower than the preset pressure value.

[0062] In this technical solution, the pressure control system 700 is disposed between the driving component 320 and the test hose 400. The pressure control system 700 can monitor and control in real time the pressure conditions transmitted to the test hose 400 during the test, and can directly apply control to the driving component 320 based on the monitoring results, ensuring that the pressure is stable and meets the set requirements throughout the test process, while ensuring efficient cooperation among all components.

[0063] During the test process, the pressure control system 700 is responsible for monitoring the pressure inside the test hose 400 and executing corresponding actions. Specifically, during the entire swing test of the metal hose, it constantly monitors the pressure value inside the test hose 400. If the pressure inside the test hose 400 is lower than the preset pressure value, which is set according to specific test requirements and safety standards before the test, at this time, the pressure control system 700 will quickly exert its control function and immediately send an instruction to the driving component 320 to precisely control the driving component 320 to stop working.

[0064] If the pressure inside the test hose 400 abnormally decreases, it indicates that there may be potential safety hazard problems such as hose rupture or loose connection. Immediately stopping the driving component 320 at this time can effectively prevent the gradual expansion of safety accidents caused by continuous testing and prevent more serious damage to operators, the surrounding environment, and equipment due to out-of-control test conditions. Secondly, from the perspective of test accuracy, stable pressure conditions are an important prerequisite for ensuring accurate and reliable swing test data. Once the pressure does not meet the preset value, it may affect the physical properties and response performance of the test hose 400 during swinging. By automatically stopping the driving component 320, it can timely interrupt the non-compliant test operation, avoid misleading the test conclusion due to poor pressure conditions, and provide guarantee for subsequent readjusting test parameters to conduct accurate and reliable tests.

[0065] Exemplarily, the pressure control system 700 includes a pressure regulating component 710 and a controller 720. The pressure regulating component 710 is connected to the lower end of the test hose 400, and the other end of the test hose 400 is in a closed state. The controller 720 is electrically connected between the driving component 320 and the pressure regulating component 710 to achieve the above control and regulation functions.

[0066] As Figures 1 to 3 shown, in some instances, the above swing member 310 further includes: an angle sensor 313 disposed on the above swing rod 312 for detecting the swing angle of the above swing rod 312; a force sensor 314 disposed on the above driving component 320 for detecting the torque applied to the above swing rod 312.

[0067] In this technical solution, the angle sensor 313 is arranged on the swing rod 312 and can directly and accurately measure the swing angle of the swing rod 312. Since the angle sensor 313 is directly and tightly combined with the swing rod 312 without excessive intermediate transfer links, the measurement error can be minimized, and the angle change of the swing rod 312 during the test can be obtained in real time and accurately.

[0068] During the entire swing test of the metal hose, the angle sensor 313 can continuously monitor the swing angle of the swing rod 312. For the test, it is crucial to understand the swing angle parameters of the swing rod 312. Different test purposes and the specifications of the test hose 400 have different requirements for the swing angle. For example, some tests need to simulate the small-angle swing stress suffered by the metal hose 400 in actual use, while some need to test its performance under large-angle swings; the swing angle data accurately measured by the angle sensor 313 can provide intuitive parameter feedback for the operator. On the one hand, the operator can judge whether the test is carried out within the predetermined angle range and frequency based on these data to ensure the consistency and accuracy of the test conditions; on the other hand, these data can also be used as an important basis for subsequent test data analysis, helping researchers analyze the internal stress distribution, material fatigue characteristics, etc. of the test hose 400 at different swing angles in more depth, providing strong data support for improving the design of the test hose 400 or optimizing its manufacturing process.

[0069] The force sensor 314 is arranged on the driving component 320 and can accurately detect the torque exerted by the driving component 320 on the swing rod 312. By installing the force sensor 314 on the driving component 320, the magnitude and change of the force exerted by the driving component 320 on the swing rod 312 during operation can be directly sensed, ensuring that the measured data truly reflects the actual dynamic situation acting on the swing rod 312.

[0070] The main function of the force sensor 314 is to detect the torque applied to the swing rod 312 in real time. During the swing test, different test requirements not only involve the control of the swing angle, but also require precise control of the force acting on the test hose 400, thereby ensuring the accuracy and reliability of the test results. First, the operator can adjust the working parameters of the driving component 320 based on these data to ensure that the force acting on the test hose 400 remains within a predetermined range in each test, avoiding large errors in the test results caused by unstable force magnitude or exceeding the test design requirements. Second, the combination of the torque data and the swing angle data can further analyze the force state of the test hose 400 during the swing process. For example, by analyzing the change in the torque magnitude at different angles, it is possible to better simulate the force condition of the test hose 400 in the actual use scenario, which helps researchers deeply study issues such as the mechanical properties and failure mechanism of the test hose 400 under alternating loads.

[0071] The setting of the angle sensor 313 and the force sensor 314 in the swing member 310 enriches the data monitoring function of the metal hose swing test device, helps researchers obtain more comprehensive and accurate test data, deeply carry out relevant research and testing work, and improve the scientific nature, accuracy of the test results and the simulation accuracy of the actual application scenario.
