[0001] The invention relates to the technical field of building facilities, and in particular to a fatigue performance testing device for an assembled support and hanger. Background Art

[0002] Prefabricated supports and hangers are used in municipal and construction projects, with the medium temperature of -20℃~150℃, the system pressure less than or equal to 1.6MPa, and the nominal size of the pipe being DN10~DN300 for water supply and drainage, gas, heat, electricity, heating, ventilation, air conditioning and fire protection systems, with gravity as the main load. According to the national standard, the fatigue performance of prefabricated support and hanger components must meet the performance requirements, that is, a vertical fatigue load is applied perpendicular to the pipeline, the load amplitude is 0.18×(1±30%)kN, and the frequency is 5Hz. At present, there is no plan to conduct relevant tests on the fatigue performance of prefabricated support and hanger components with gravity as the main load. Summary of the invention

[0003] The present invention proposes a fatigue performance testing device for prefabricated supports and hangers, so as to solve the defect in the prior art that there is no relevant test scheme for the fatigue performance of prefabricated supports and hangers with gravity as the main load. By proposing relevant equipment for fatigue performance testing of prefabricated supports and hangers, the fatigue performance testing requirements of vertical loads, small forces and high frequencies of prefabricated supports and hangers are met. At the same time, the testing equipment has the advantages of simple structure, easy installation, small space occupation, strong adaptability to product types and easy operation.

[0004] A fatigue performance test device for an assembled support and hanger provided by the present invention comprises: a frame assembly, a hanger assembly and a force application assembly;

[0005] The frame assembly has an interior formed with a receiving space for receiving the hanger assembly and the force-applying assembly;

[0006] At least two of the hanger assemblies are arranged at intervals and are respectively connected to the frame assembly to form a hanging structure for hanging the pipe body;

[0007] The force-applying assembly is connected to the frame assembly and applies a load to the tube body for testing the fatigue performance of the hanger assembly.

[0008] According to one embodiment of the present invention, the frame assembly comprises: a top frame, a middle frame, a support frame, a bottom frame and a frame connecting beam;

[0009] The top frame, the middle frame and the bottom frame are arranged at intervals;

[0010] The support frames are respectively connected to two opposite sides of the middle frame;

[0011] The frame connecting beams are respectively connected to the top frame, the middle frame and the bottom frame;

[0012] Wherein, the force applying component is connected to the supporting frame.

[0013] Specifically, this embodiment provides an implementation method of a frame assembly, which forms a storage space for accommodating a tube body, a hanger assembly and a force-applying assembly by setting a top frame, a middle frame, a bottom frame and a frame connecting beam, and relevant tests on the fatigue performance of the hanger assembly are carried out in the storage space.

[0014] Furthermore, the top frame, the middle frame, the bottom frame and the frame connecting beams can all be made of profiles, which facilitates the rapid disassembly and installation of the frame components, and can be transported to the construction site for assembly according to construction requirements, thereby ensuring the construction quality.

[0015] According to one embodiment of the present invention, the frame assembly further comprises: a first connecting beam and a first connecting plate;

[0016] The first connecting beam is connected to two opposite sides of the top frame corresponding to the supporting frame respectively;

[0017] The first connecting plate and the first connecting beam are spaced apart to form a hoisting structure for clamping the top frame;

[0018] Wherein, the hanger assembly is connected with the first connecting beam to form a first hanger;

[0019] The gap between the first connecting plate and the first connecting beam is adjustable.

[0020] Specifically, this embodiment provides another implementation of the frame assembly, in which a first hanger is formed by the hanger assembly and the first connecting beam, thereby realizing the simulation of the top hanging structure of the pipe body by the hanger assembly.

[0021] In actual applications, the spacing between the hanger assemblies may change with the length of the pipe body or related structures, resulting in changes in the setting position, height and distance of the hanger assemblies in the accommodating space. Therefore, by adjusting the gap between the first connecting plate and the first connecting beam, the position of each first hanger is adjusted, thereby realizing the lifting of pipe bodies of different sizes and structures, and then realizing the fatigue performance test of the hanger assembly at different positions, heights and distances between the two hanger assemblies through the force-applying assembly.

[0022] It should be noted that structures such as slideways that cooperate with the first connecting plate or the first connecting beam may be provided on the top frame and the middle frame. In order to save space, the present invention does not provide too much description, and this part of the setting may refer to relevant designs in the art.

[0023] In an application scenario, the gap between the first connecting plate and the first connecting beam is adjusted by bolts.

[0024] In one application scenario, slideways are provided on the top frame and the middle frame to allow the first connecting plate and the first connecting beam to adjust their relative positions along the extension direction of the slideways, thereby achieving adjustment of the hanger assembly at different positions, heights and distances.

[0025] According to one embodiment of the present invention, the frame assembly further comprises: a second connecting beam and a second connecting plate;

[0026] The second connecting beam is respectively connected to two opposite sides of the top frame and the middle frame;

[0027] The second connecting plate and the second connecting beam are spaced apart to form a hoisting structure for clamping the top frame and the middle frame;

[0028] Wherein, the hanger assembly is connected with the second connecting beam to form a second hanger;

[0029] The gap between the second connecting plate and the second connecting beam is adjustable.

[0030] Specifically, this embodiment provides another implementation of the frame assembly, in which a second hanger is formed by the hanger assembly and the second connecting beam, thereby realizing the simulation of the side hanging structure of the pipe body by the hanger assembly.

[0031] In actual applications, the spacing between the hanger assemblies may change with the length of the pipe body or related structures, resulting in changes in the setting position, height and distance of the hanger assemblies in the accommodating space. Therefore, by adjusting the gap between the second connecting plate and the second connecting beam, the position of each second hanger is adjusted, thereby realizing the lifting of pipe bodies of different sizes and structures, and then realizing the fatigue performance test of the hanger assembly at different positions, heights and distances between the two hanger assemblies through the force-applying assembly.

[0032] It should be noted that structures such as slideways that cooperate with the second connecting plate or the second connecting beam may be provided on the top frame and the middle frame. In order to save space, the present invention does not provide too much description, and this part of the setting may refer to relevant designs in the art.

[0033] In an application scenario, the gap between the second connecting plate and the second connecting beam is adjusted by bolts.

[0034] In one application scenario, slideways are provided on the top frame and the middle frame to allow the second connecting plate and the second connecting beam to adjust their relative positions along the extension direction of the slideways, thereby achieving adjustment of the hanger assembly at different positions, heights and distances.

[0035] According to one embodiment of the present invention, the hanger assembly comprises: a first hanger rod, a second hanger rod and a pipe clamp;

[0036] In the first hanger, the first hanger rod is arranged in parallel with the first connecting beam, two second hanger rods are respectively connected to the first hanger rod and the first connecting beam, and the pipe clamp is arranged on the first hanger rod;

[0037] In the second hanger, the first hanger rod is vertically arranged with the second connecting beam, the second hanger rod is connected with the first hanger rod and the second connecting beam, and the pipe clamp is arranged on the first hanger rod.

[0038] Specifically, this embodiment provides an implementation of a hanger assembly, wherein the first hanger rod and the second hanger rod form a structure for hanging a pipe body in a receiving space, and the pipe clamp ensures the stability of the connection between the pipe body and the first hanger rod.

[0039] It should be noted that the pipe clamp and the first hanger rod are fixed by connecting parts such as channel steel locks or bolts. At the same time, the first hanger rod is an open channel steel with teeth. The pipe clamp can slide left and right on the first hanger rod to adjust its position, and pipe clamps of different sizes can be connected to the first hanger rod according to the diameters of different pipe bodies.

[0040] According to one embodiment of the present invention, the second hanger rod is a telescopic rod capable of adjusting the telescopic length, and is used to adjust the hoisting height of the hanger assembly;

[0041] Wherein, in the first hanger, the second hanger rod can also slide along the extension direction of the first connecting beam;

[0042] Alternatively, in the second hanger, the first hanger rod and the second hanger rod are capable of sliding along an extending direction of the second connecting beam.

[0043] Specifically, this embodiment provides another implementation of the hanger assembly, by setting the second hanger rod as a telescopic rod that can be extended and retracted, so that the hanger assembly can adjust the hoisting height in the vertical direction, or adjust the hoisting position of the hanger assembly in the horizontal direction.

[0044] Furthermore, the second hanger rod can slide along the extension direction of the first connecting beam, and the first hanger rod and the second hanger rod can slide along the extension direction of the second connecting beam, so that the position of the hanger assembly in the two-dimensional plane of the accommodating space is more flexible.

[0045] According to one embodiment of the present invention, at least two groups of the hanger assemblies are spaced apart in the accommodating space.

[0046] Specifically, this embodiment provides an implementation method for arranging a certain number of hanger assemblies in the accommodating space, and the hanging of pipes of different lengths is achieved by arranging multiple groups of hanger assemblies.

[0047] Furthermore, since the pipe body may have multiple lifting positions at multiple heights due to elbows or multiple test positions in actual construction, the needs of lifting at different heights can be met through multiple sets of hanger assemblies, thereby realizing fatigue testing of the hanger assemblies at corresponding positions to meet various working conditions of the hanger assemblies.

[0048] In an application scenario, there is a height difference between the two hanger assemblies in the height direction, and there is also a horizontal position difference in the horizontal lifting position. This setting ensures the lifting of the pipe body when there is a height difference in the bending part or the pipe body test. In other words, by setting the hanger assemblies at different lifting heights, the lifting of pipes of different shapes can be achieved.

[0049] In another application scenario, the force-applying component applies force downward in the vertical direction and applies load to the pipe body through the angle. During the test, the force-applying component can repeatedly apply load at a certain frequency, or continuously apply a certain load until the pipe body reaches the load limit, and then obtain the corresponding parameters of the hanger assembly according to the above-mentioned test method.

[0050] According to an embodiment of the present invention, the force applying assembly comprises: a force applying support seat, a force applying cylinder, a sensor, a force applying connecting rod and a clamp;

[0051] The force-applying support seat is connected to the support frame;

[0052] The force-applying cylinder is connected to the force-applying support seat;

[0053] The sensor is arranged at one end of the extension rod of the force-applying cylinder;

[0054] One end of the force-applying connecting rod is connected to the sensor, and the other end of the force-applying connecting rod is connected to the clamp;

[0055] The clamp clamps the tube body and is used to apply a load to the tube body under the action of the force-applying cylinder.

[0056] Specifically, this embodiment provides an implementation of a force-applying assembly, which achieves the fixation and support of the force-applying cylinder body by disposing a force-applying support seat.

[0057] Furthermore, by providing a force-applying cylinder and a sensor, the measurement of the load force applied by the force-applying cylinder to the tube body is achieved.

[0058] Furthermore, the function of clamping is to form a circumferential clamping effect on the tube body. It should be noted that the function of the clamp is not to clamp the tube body, but to apply the force of the force cylinder to the tube body after connecting the force connecting rod with the sensor and the force cylinder.

[0059] Furthermore, by connecting the force-applying support seat with the support frame of the middle frame, the relative position of the force-applying cylinder body can be adjusted in the vertical direction.

[0060] According to one embodiment of the present invention, the clamp comprises: a first pipe clamp and a second pipe clamp;

[0061] The first pipe hoop is connected to the force-applying connecting rod;

[0062] The second pipe hoop is spaced apart from the first pipe hoop and is buckled to form a clamping structure for clamping the pipe body.

[0063] Specifically, this embodiment provides an implementation of a clamp, which realizes circumferential clamping of the pipe body by providing a first pipe clamp and a second pipe clamp, thereby ensuring the application of circumferential load to the pipe body.

[0064] It should be noted that when the force cylinder is not working, the first pipe clamp and the second pipe clamp are merely wrapped around the outside of the pipe body and do not apply load to the pipe body. When in working condition, the fixture applies load to the pipe body, thereby realizing the test of fatigue parameters related to the hanger assembly.

[0065] According to an embodiment of the present invention, the relative position between the force-applying support seat and the support frame can be adjusted in the horizontal direction and the vertical direction;

[0066] The support frame and the middle frame are slidably matched to adjust the horizontal relative position between the support frame and the middle frame.

[0067] Specifically, this embodiment provides an implementation method of a force support seat. By arranging a sliding fit between the force support seat and the support frame, and between the support frame and the middle frame, the relative position between the force cylinder body and the tube body can be adjusted, thereby meeting the space requirements for fatigue testing in a larger range.

[0068] It should be noted that the middle frame can be provided with slide rails, slideways, etc. that cooperate with the support frame. In order to save space, the present invention does not provide too much description of the sliding cooperation between the force support seat and the support frame. This part of the setting can refer to the relevant design in the field.

[0069] In an application scenario, the top frame, the middle frame, the bottom frame, the supporting frame and the frame connecting beams can all be made of profiles, and slideways can be processed on the profiles, and slide rails can be set. For how to process slideways on the profiles and install slide rails, this part can refer to the relevant settings in the field, and the present invention will not go into too much detail on this.

[0070] According to one embodiment of the present invention, it further includes: a terminal module, which is arranged between the top frame and the middle frame and is communicatively connected with the force-applying component for displaying and setting parameters of the fatigue performance test.

[0071] Specifically, this embodiment provides an implementation method of a terminal module, which realizes the setting of fatigue test parameters and the display of corresponding feedback parameters of the pipe body under load during the test by setting the terminal module.

[0072] It should be noted that the bottom frame is mainly used to place related electrical components, electrical boxes, etc.

[0073] The above one or more technical solutions in the present invention have at least one of the following technical effects: a fatigue performance test device for a prefabricated support and hanger provided by the present invention meets the fatigue performance test requirements of the prefabricated support and hanger for vertical load, small force and high frequency by proposing related equipment for fatigue performance test of prefabricated support and hanger components. At the same time, the test equipment has the advantages of simple structure, easy installation, small space occupation, strong adaptability to product types and easy operation.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0094] In some specific embodiments of the present invention, Figures 1 to 7 As shown, the present scheme provides a fatigue performance test device for an assembled support hanger, comprising: a frame assembly 20, a hanger assembly 30 and a force-applying assembly 40; a storage space for accommodating the hanger assembly 30 and the force-applying assembly 40 is formed inside the frame assembly 20; at least two hanger assemblies 30 are arranged at intervals and are respectively connected to the frame assembly 20 to form a hanging structure for hanging a pipe body 10; the force-applying assembly 40 is connected to the frame assembly 20, and applies a load to the pipe body 10 for testing the fatigue performance of the hanger assembly 30.

[0095] In detail, the present invention proposes a fatigue performance testing device for prefabricated supports and hangers, so as to solve the defect in the prior art that there is no relevant test scheme for the fatigue performance of prefabricated supports and hangers with gravity as the main load. By proposing relevant equipment for fatigue performance testing of prefabricated support and hanger components, the fatigue performance testing requirements of prefabricated supports and hangers with vertical loads, small forces and high frequencies are met. At the same time, the testing equipment has the advantages of simple structure, easy installation, small space occupation, strong adaptability to product types and easy operation.

[0096] In some possible embodiments of the present invention, the frame assembly 20 includes: a top frame 21, a middle frame 22, a support frame 25, a bottom frame 23 and a frame connecting beam 24; the top frame 21, the middle frame 22 and the bottom frame 23 are arranged at intervals; the support frame 25 is respectively connected to two opposite sides of the middle frame 22; the frame connecting beam 24 is respectively connected to the top frame 21, the middle frame 22 and the bottom frame 23; wherein, the force-applying assembly 40 is connected to the support frame 25.

[0097] Specifically, this embodiment provides an implementation method of a frame assembly 20, by providing a top frame 21, a middle frame 22, a bottom frame 23 and a frame connecting beam 24, a receiving space for accommodating the tube body 10, the hanger assembly 30 and the force-applying assembly 40 is formed, and relevant tests on the fatigue performance of the hanger assembly 30 are carried out in the receiving space.

[0098] Furthermore, the top frame 21, the middle frame 22, the bottom frame 23 and the frame connecting beam 24 can all be made of profiles, which facilitates the rapid disassembly and installation of the frame assembly 20, and can be transported to the construction site for assembly according to construction requirements, thereby ensuring the construction quality.

[0099] In some possible embodiments of the present invention, the frame assembly 20 also includes: a first connecting beam 26 and a first connecting plate 27; the first connecting beam 26 is connected to two opposite sides of the top frame 21 corresponding to the supporting frame 25; the first connecting plate 27 and the first connecting beam 26 are spaced apart to form a lifting structure for clamping the top frame 21; wherein the hanger assembly 30 is connected to the first connecting beam 26 to form a first hanger; the gap between the first connecting plate 27 and the first connecting beam 26 is adjustable.

[0100] Specifically, this embodiment provides another implementation of the frame assembly 20 , in which the hanger assembly 30 and the first connecting beam 26 form a first hanger, thereby achieving simulation of the top hanging structure of the pipe body 10 by the hanger assembly 30 .

[0101] In actual applications, the spacing between the hanger assemblies 30 may change with the length of the tube body 10 or related structures, resulting in changes in the setting position, height and distance of the hanger assemblies 30 in the accommodating space. Therefore, by adjusting the gap between the first connecting plate 27 and the first connecting beam 26, the position of each first hanger is adjusted, thereby realizing the hanging of tube bodies 10 of different sizes and structures, and then realizing the fatigue performance test of the hanger assembly 30 at different positions, heights and distances between the two hanger assemblies 30 through the force-applying assembly 40.

[0102] It should be noted that structures such as slideways that cooperate with the first connecting plate 27 or the first connecting beam 26 may be provided on the top frame 21 and the middle frame 22. In order to save space, the present invention does not provide too much description, and this part of the setting can refer to the relevant design in the field.

[0103] In an application scenario, the gap between the first connecting plate 27 and the first connecting beam 26 is adjusted by bolts.

[0104] In an application scenario, slideways are provided on the top frame 21 and the middle frame 22 to allow the first connecting plate 27 and the first connecting beam 26 to adjust their relative positions along the extension direction of the slideways, thereby achieving adjustment of the hanger assembly 30 at different positions, heights and distances.

[0105] In some possible embodiments of the present invention, the frame assembly 20 also includes: a second connecting beam 28 and a second connecting plate 29; the second connecting beam 28 is respectively connected to two opposite sides of the top frame 21 and the middle frame 22; the second connecting plate 29 is spaced apart from the second connecting beam 28 to form a lifting structure for clamping the top frame 21 and the middle frame 22; wherein the hanger assembly 30 is connected to the second connecting beam 28 to form a second support hanger; the gap between the second connecting plate 29 and the second connecting beam 28 is adjustable.

[0106] Specifically, this embodiment provides another implementation of the frame assembly 20 , in which the hanger assembly 30 and the second connecting beam 28 form a second hanger, thereby achieving simulation of the side hanging structure of the pipe body 10 by the hanger assembly 30 .

[0107] In actual applications, the spacing between the hanger assemblies 30 may change with the length of the tube body 10 or related structures, resulting in changes in the setting position, height and distance of the hanger assemblies 30 in the accommodating space. Therefore, by adjusting the gap between the second connecting plate 29 and the second connecting beam 28, the position of each second hanger is adjusted, thereby realizing the lifting of tube bodies 10 of different sizes and structures, and then realizing the fatigue performance test of the hanger assembly 30 at different positions, heights and distances between the two hanger assemblies 30 through the force-applying assembly 40.

[0108] It should be noted that structures such as slideways that cooperate with the second connecting plate 29 or the second connecting beam 28 may be provided on the top frame 21 and the middle frame 22. In order to save space, the present invention does not provide too much description, and this part of the setting can refer to the relevant design in the field.

[0109] In an application scenario, the gap between the second connecting plate 29 and the second connecting beam 28 is adjusted by bolts.

[0110] In an application scenario, slideways are provided on the top frame 21 and the middle frame 22 to allow the second connecting plate 29 and the second connecting beam 28 to adjust their relative positions along the extension direction of the slideways, thereby achieving adjustment of the hanger assembly 30 at different positions, heights and distances.

[0111] In some possible embodiments of the present invention, the hanger assembly 30 includes: a first hanger rod 31, a second hanger rod 32 and a pipe clamp 33; in the first hanger, the first hanger rod 31 is arranged parallel to the first connecting beam 26, the two second hanger rods 32 are respectively connected to the first hanger rod 31 and the first connecting beam 26, and the pipe clamp 33 is arranged on the first hanger rod 31; in the second hanger, the first hanger rod 31 is respectively arranged perpendicular to the second connecting beam 28, the second hanger rod 32 is respectively connected to the first hanger rod 31 and the second connecting beam 28, and the pipe clamp 33 is arranged on the first hanger rod 31.

[0112] Specifically, this embodiment provides an implementation of a hanger assembly 30 , wherein the first hanger rod 31 and the second hanger rod 32 form a structure for hanging the pipe body 10 in the accommodating space, and the pipe clamp 33 ensures the stability of the connection between the pipe body 10 and the first hanger rod 31 .

[0113] It should be noted that the pipe clamp 33 and the first hanger rod 31 are fixed by connecting parts such as channel steel locks or bolts. At the same time, the first hanger rod 31 is an open channel steel with teeth. The pipe clamp 33 can slide left and right on the first hanger rod 31 to adjust its position, and pipe clamps 33 of different sizes can be connected to the first hanger rod 31 according to the diameters of different pipe bodies 10.

[0114] In some possible embodiments of the present invention, the second hanger rod 32 is a telescopic rod capable of adjusting the telescopic length, and is used to adjust the hoisting height of the hanger assembly 30; wherein, in the first hanger, the second hanger rod 32 can also slide along the extension direction of the first connecting beam 26; or, in the second hanger, the first hanger rod 31 and the second hanger rod 32 can slide along the extension direction of the second connecting beam 28.

[0115] Specifically, this embodiment provides another implementation of the hanger assembly 30, by setting the second hanger rod 32 as a telescopic rod that can be extended and retracted, so that the hanger assembly 30 can adjust the hoisting height in the vertical direction, or adjust the hoisting position of the hanger assembly 30 in the horizontal direction.

[0116] Furthermore, the second hanger rod 32 can slide along the extension direction of the first connecting beam 26, and the first hanger rod 31 and the second hanger rod 32 can slide along the extension direction of the second connecting beam 28, so that the position of the hanger assembly 30 in the two-dimensional plane of the accommodating space is more flexible.

[0117] In some possible embodiments of the present invention, at least two groups of hanger assemblies 30 are spaced apart in the accommodation space.

[0118] Specifically, this embodiment provides an implementation method for setting a certain number of hanger assemblies 30 in the accommodating space, and the hanging of pipe bodies 10 of different lengths is achieved by setting a plurality of groups of hanger assemblies 30 .

[0119] Furthermore, since the pipe body 10 may have multiple lifting positions at multiple heights due to elbows or multiple test positions during actual construction, the requirements for lifting at different heights can be met through multiple groups of hanger assemblies 30, thereby achieving fatigue testing of the hanger assemblies 30 at corresponding positions to meet various working conditions of the hanger assemblies 30.

[0120] In an application scenario, there is a height difference between the two hanger assemblies 30 in the height direction, and there is also a horizontal position difference in the horizontal lifting position. This setting ensures the lifting of the bending part of the tube body 10 or the test of the tube body 10 when there is a height difference. That is to say, by setting the hanger assemblies 30 at different lifting heights, the lifting of tube bodies 10 of different shapes can be achieved.

[0121] In another application scenario, the force-applying component 40 applies force downward in the vertical direction and realizes the load application to the tube body 10 through the angle. During the test, the force-applying component 40 can repeatedly apply the load at a certain frequency, or continuously apply a certain load until the tube body 10 reaches the load-bearing limit, and then obtain the corresponding parameters of the hanger assembly 30 according to the above-mentioned test method.

[0122] In some possible embodiments of the present invention, the force-applying assembly 40 includes: a force-applying support seat 41, a force-applying cylinder body 42, a sensor 43, a force-applying connecting rod 44 and a clamp 45; the force-applying support seat 41 is connected to the support frame 25; the force-applying cylinder body 42 is connected to the force-applying support seat 41; the sensor 43 is arranged at one end of the extending rod of the force-applying cylinder body 42; one end of the force-applying connecting rod 44 is connected to the sensor 43, and the other end of the force-applying connecting rod 44 is connected to the clamp 45; the clamp 45 clamps the tube body 10, and is used to apply a load to the tube body 10 under the action of the force-applying cylinder body 42.

[0123] Specifically, this embodiment provides an implementation of a force-applying assembly 40 , which implements the fixation and support of the force-applying cylinder 42 through the provision of a force-applying support seat 41 .

[0124] Furthermore, by providing the force-applying cylinder 42 and the sensor 43 , the measurement of the load force applied by the force-applying cylinder 42 to the tube body 10 is achieved.

[0125] Furthermore, the function of clamping is to form a circumferential clamping effect on the tube body 10. It should be noted that the function of the clamp 45 is not to clamp the tube body 10, but to apply the force of the force cylinder 42 to the tube body 10 after being connected to the sensor 43 and the force cylinder 42 through the force connecting rod 44.

[0126] Furthermore, by connecting the force-applying support seat 41 to the support frame 25 of the middle frame 22 , the relative position of the force-applying cylinder 42 in the vertical direction can be adjusted.

[0127] In some possible embodiments of the present invention, the clamp 45 includes: a first pipe hoop 46 and a second pipe hoop 47; the first pipe hoop 46 is connected to the force-applying connecting rod 44; the second pipe hoop 47 is spaced apart from the first pipe hoop 46 and buckled to form a clamping structure for clamping the tube body 10.

[0128] Specifically, this embodiment provides an implementation of a clamp 45 , which realizes circumferential clamping of the pipe body 10 by providing a first pipe clamp 46 and a second pipe clamp 47 , thereby ensuring the application of circumferential load to the pipe body 10 .

[0129] It should be noted that, when the force cylinder 42 is not in working state, the first pipe clamp 46 and the second pipe clamp 47 are merely wrapped around the outside of the pipe body 10 and do not apply load to the pipe body 10. In the working state, the clamp 45 applies load to the pipe body 10, thereby realizing the test of the fatigue parameters related to the hanger assembly 30.

[0130] In some possible embodiments of the present invention, the relative position between the force support seat 41 and the support frame 25 can be adjusted along the horizontal direction and the vertical direction; the support frame 25 and the middle frame 22 are slidably matched to adjust the horizontal relative position between the support frame 25 and the middle frame 22.

[0131] Specifically, this embodiment provides an implementation method of a force support seat 41. By arranging a sliding fit between the force support seat 41 and the support frame 25, and between the support frame 25 and the middle frame 22, the relative position between the force cylinder body 42 and the tube body 10 is adjusted, thereby meeting the space requirements for fatigue testing in a larger range.

[0132] It should be noted that the middle frame 22 may be provided with slide rails, slideways, etc. that cooperate with the support frame 25. In order to save space, the present invention does not provide too much description of the sliding cooperation between the force support seat 41 and the support frame 25. This part of the setting can refer to the relevant design in the field.

[0133] In an application scenario, the top frame 21, the middle frame 22, the bottom frame 23, the support frame 25 and the frame connecting beam 24 can all be made of profiles, and slideways can be processed on the profiles, and slide rails can be set. For how to process slideways on the profiles and install slide rails, this part can refer to the relevant settings in the field, and the present invention will not go into too much detail on this.

[0134] In some possible embodiments of the present invention, it further includes: a terminal module 50, which is arranged between the top frame 21 and the middle frame 22 and is communicated with the force application component 40 for displaying and setting parameters of the fatigue performance test.

[0135] Specifically, this embodiment provides an implementation of a terminal module 50 , by setting the terminal module 50 , the setting of fatigue test parameters and the display of corresponding feedback parameters of the pipe body 10 under load during the test are realized.

[0136] It should be noted that the bottom frame 23 is mainly used to place related electrical components, electrical cabinets, etc.
