[0026] The following reference Figures 1 to 6 This application describes a corner post test fixture for a solid hydrogen storage tank support frame according to some embodiments.

[0027] See Figures 1 to 6 As shown, an embodiment of this application provides a corner column test fixture for a solid hydrogen storage tank support frame, including: a working platform 1 and two positioning mechanisms 2; wherein, the two positioning mechanisms 2 are spaced apart on the working platform 1 along a first preset direction a, and the space between the two positioning mechanisms 2 is used to place the test piece 10; Each positioning mechanism 2 includes a driving device 21, a connecting member 22, and a positioning member 23. The fixed end of the driving device 21 is fixed to the working platform 1, and the driving end of the driving device 21 is connected to the connecting member 22. The positioning member 23 is disposed on the connecting member 22, and the positioning member 23 is used to be inserted into the mounting hole 101 at the bottom of the test piece 10; the driving device 21 can drive the connecting member 22 to move the positioning member 23 toward or away from another positioning member 23 along the first preset direction a.

[0028] Based on the structure described above, the usage process of the corner column test fixture for the solid hydrogen storage tank support frame provided in this application is roughly as follows: First, two driving devices 21 drive two connecting members 22 to move two corresponding positioning members 23, thereby adjusting the distance between the two positioning members 23 to a preset distance. Then, the test piece 10, such as a corner post, is placed above the working platform 1, with the two mounting holes 101 below the test piece 10, such as the corner post, respectively located directly above the two positioning members 23. Then, the test piece 10, such as the corner post, is lowered and placed on the working platform 1, and at this time, the two positioning members 23 are respectively inserted into the two corresponding mounting holes 101, thereby achieving the positioning of the left and right ends of the corner post. Then, the two driving devices 21 are activated, and the two driving devices 21 drive the two positioning members 23 to move in opposite directions, thereby performing a tensile test on the corner post.

[0029] As can be seen, in the corner column test fixture of the solid hydrogen storage tank support frame provided in this application, the distance between the two positioning components 23 can be adjusted by the drive device 21, thereby meeting the requirements for testing test pieces 10 of different lengths, such as corner columns. It has a wider range of applications and is simple, convenient, time-saving and labor-saving to operate.

[0030] It should be noted that the corner post includes the upright and the corner fittings at the ends. The corner fitting is a hollow square structure with a mounting hole 101 at its bottom. This mounting hole 101 is a pre-existing hole on the corner fitting, designed to fix the frame composed of the corner posts to a location such as a vehicle. Therefore, this application utilizes the existing mounting hole 101 in conjunction with the positioning component 23, eliminating the need to create new holes on the corner post, thus saving time and effort. Of course, the structure of the corner post is not limited to this and can be selected according to actual needs.

[0031] In this embodiment, preferably, as follows: Figure 1 As shown, the corner column test fixture of the solid hydrogen storage tank support frame also includes a lifting device 3, and the fixed end of the lifting device 3 is fixed below the table surface 12 of the work platform 1. The work platform 1 has a table 12 with a clearance through hole extending along its height direction, and the drive end of the lifting device 3 can pass through the clearance through hole to push and unload the test piece 10 placed on the table 12. As can be seen from the structure described above, after the test is completed, the lifting device 3 can be used to apply a pushing force to the bottom of the test piece 10, such as the corner post, so that the corner post falls off the work platform 1, which plays the role of automatic unloading, which helps to improve work efficiency, save labor, and avoid problems such as jamming, tooling deformation or cracking when replacing the test piece 10, such as the corner post.

[0032] Furthermore, preferably, the lifting device 3 is a cylinder. Of course, it is not limited to this and can also be a hydraulic cylinder, etc., depending on the actual needs.

[0033] Furthermore, preferably, the working platform 1 includes multiple support columns 11 and a table surface 12; wherein, the multiple support columns 11 are fixed to the bottom of the table surface 12; the aforementioned positioning mechanisms 2 are all disposed on the table surface 12, and the lifting device 3 is disposed below the table surface 12 and located between the multiple support columns 11. Preferably, the fixed end of the lifting device 3 is directly supported on the ground. Of course, it is not limited to this; the fixed end of the lifting device 3 can also be connected to the table surface 12 and / or the multiple support columns 11 through a bracket. It should be noted that the aforementioned lifting device 3 may also be omitted, and manual unloading may be used, depending on actual needs. In this embodiment, preferably, as follows: Figure 4As shown, the connecting member 22 includes a connecting part 221 and a sliding part 222 connected to each other; wherein, the connecting part 221 is connected to the driving end of the driving device 21, and the sliding part 222 is slidably disposed on the working platform 1; the positioning member 23 is disposed on the sliding part 222. As can be seen from the structure described above, the connecting part 221 connects the sliding part 222 and the driving end of the driving device 21 together, and plays the role of transfer; the sliding part 222 plays the role of supporting the positioning member 23 and slidingly engaging with the table surface 12 of the work platform 1.

[0034] Furthermore, preferably, the connecting part 221 and the sliding part 222 form an L-shaped structure, and preferably an L-shaped plate, which meets the usage requirements and has a simple structure that is easy to process and manufacture.

[0035] In this embodiment, preferably, as follows: Figure 2 and Figure 4 As shown, any positioning mechanism 2 also includes two guide rails 4 disposed on the working platform 1, and along a direction perpendicular to the first preset direction a, the two guide rails 4 are respectively disposed on opposite sides of the sliding part 222, and the opposite sides of the sliding part 222 are slidably connected to the two guide rails 4 that correspond one-to-one. As can be seen from the structure described above, the two guide rails 4 serve to guide the sliding part 222 during the sliding process, preventing the sliding part 222 from deviating, thereby ensuring the subsequent fitting accuracy with the test piece 10, such as a corner post.

[0036] Of course, the structure of two guide rails 4 can also be omitted, depending on the actual needs. In this embodiment, preferably, as follows: Figure 2 As shown, any positioning mechanism 2 also includes two limiting members 5 disposed on the working platform 1, and along a direction perpendicular to the first preset direction a, the two limiting members 5 are respectively disposed on opposite sides of the guide rail 4; The limiting component 5 includes a base 51 and a limiting plate 52. The base 51 is disposed on the side of the corresponding guide rail 4 away from the sliding part 222, and the limiting plate 52 is disposed on the top of the base 51 and pressed against the top of the guide rail 4. As can be seen from the structure described above, the two limiting components 5 respectively limit the two guide rails 4. Specifically, the base 51 limits the side of the guide rail 4, and the limiting plate 52 limits the top of the guide rail 4, thereby making the guide rail 4 more secure and stable.

[0037] Furthermore, preferably, the guide rail 4 can also be fixed to the work platform 1 by bolts, but of course, it is not limited to this.

[0038] In this embodiment, preferably, as follows: Figure 1 , Figures 3 to 5 As shown, the corner column test fixture of the solid hydrogen storage tank support frame also includes at least one anti-fall mechanism 6 disposed on the work platform 1, and the anti-fall mechanism 6 is used to prevent the test piece 10 placed on the work platform 1 from falling. As can be seen from the structure described above, the anti-fall mechanism 6 is set on the work platform 1, which can avoid the risk of the test piece 10, such as the corner post, falling off the work platform 1 during the test, thus helping to improve the safety and reliability of this tooling during use. In this embodiment, preferably, as follows: Figure 1 and Figure 4 As shown, the anti-fall mechanism 6 includes an anti-fall plate 61 and a rotating shaft 62; wherein, along a direction perpendicular to the first preset direction a, the anti-fall plate 61 spans across the work platform 1, and the two sides of the anti-fall plate 61 are respectively rotatably connected to the two sides of the work platform 1 through corresponding rotating shafts 62. As can be seen from the structure described above, since the anti-fall plate 61 is rotatably connected to the working platform 1 through the rotating shaft 62, after the test piece 10, such as the corner post, is assembled with the positioning component 23, the anti-fall plate 61 can be rotated so that the anti-fall plate 61 presses down on the test piece 10, such as the corner post, thereby protecting the top and sides of the test piece 10, such as the corner post, and thus avoiding the risk of the test piece 10, such as the corner post, falling off the working platform 1 during the test. In this embodiment, preferably, as follows: Figure 4 As shown, the anti-fall plate 61 has a relief groove 611 with an opening facing the test piece 10, and the relief groove 611 is used to avoid the test piece 10, such as a corner post. As can be seen from the structure described above, the anti-fall plate 61 is provided with a relief groove 611, which can effectively avoid the test piece 10, such as the corner post, and avoid interference with the test piece 10, such as the corner post. In this embodiment, preferably, as follows: Figure 1 and Figure 4 As shown, there are two anti-fall mechanisms 6, one of which is positioned close to one of the positioning mechanisms 2 along the first preset direction a, and the other is positioned close to the other positioning mechanism 2 along the first preset direction a. As can be seen from the structure described above, this application designs two anti-fall mechanisms 6 to protect the two ends of the corner post, which can further prevent the test piece 10, such as the corner post, from falling off the work platform 1 during the test, making it more reliable. In this embodiment, preferably, as follows: Figure 1As shown, both drive devices 21 are hydraulic cylinders; the corner column test fixture of the solid hydrogen storage tank support frame also includes a hydraulic oil supply device 7, which is located on one side of the work platform 1 and is connected to the two drive devices 21 respectively. As can be seen from the structure described above, the hydraulic oil supply device 7 supplies oil to two drive devices 21, that is, two oil cylinders, which makes it more convenient to use. Moreover, the working pressure of the output oil of the hydraulic oil supply device 7 can be controlled to control the tensile force of the corner column test to meet different test requirements. It should be noted that the hydraulic oil supply device 7 is existing equipment and will not be described in detail here.

[0039] In addition, it should be noted that the drive device 21 is not limited to a hydraulic cylinder, but can also be a pneumatic cylinder, etc., depending on the actual needs. In this embodiment, preferably, as follows: Figure 1 and Figure 3 As shown, the corner column test fixture of the solid hydrogen storage tank support frame also includes a support member 8 set on the platform 12 of the work platform 1, and the fixed end of the drive device 21 is fixed to the support member 8.

[0040] As can be seen from the structure described above, the support member 8 serves to support the drive device 21. Of course, this support member 8 can also be omitted, and the drive end of the drive device 21 can be directly fixed on the work platform 1. The specific choice depends on the actual needs.

[0041] Furthermore, preferably, the supporting member 8 is an L-shaped plate. Of course, it is not limited to this and can be selected according to actual needs.

[0042] In this embodiment, preferably, as follows: Figure 1 As shown, the corner column test fixture of the solid hydrogen storage tank support frame also includes a connecting shaft 9, and the connecting component 22 is connected to the drive end of the drive device 21 through the connecting shaft 9.

[0043] As can be seen from the structure described above, the connecting shaft 9 serves as a transition point, preventing the drive end of the drive device 21 from being too short and inconvenient to assemble with the connecting component 22. Of course, this connecting shaft 9 can also be omitted.

[0044] In this embodiment, preferably, as follows: Figure 1 and Figure 4 As shown, the positioning component is a pin, which is an existing structure that meets the positioning requirements and is convenient to purchase. Of course, it is not limited to this and can be selected according to actual needs.

[0045] In summary, the detailed usage process of the corner post testing fixture for the solid hydrogen storage tank support frame provided in this application is as follows: First, two driving devices 21 drive two connecting members 22 to move two corresponding positioning members 23, thereby adjusting the distance between the two positioning members 23 to a preset distance. Then, the test piece 10, such as a corner post, is placed above the working platform 1, with the two mounting holes 101 on the bottom of the test piece 10, such as the corner post, respectively located directly above the two positioning members 23. Then, the test piece 10, such as the corner post, is lowered and placed on the working platform 1, and at this time, the two positioning members 23 are respectively inserted into the two corresponding mounting holes 101, thereby achieving the positioning of the left and right ends of the test piece 10, such as the corner post. Then, the two anti-fall plates 61 are rotated so that the two anti-fall plates 61 press down on the test piece 10, such as the corner post. Then, the two driving devices 21 are activated, and the two driving devices 21 drive the two positioning members 23 to move in opposite directions, thereby performing a tensile test on the corner post.

[0046] As can be seen, using this fixture for corner column testing eliminates the need to change the fixture or adjust the position of the fixture's fixed end, thus speeding up the production process and saving production costs. In addition, the fixture has an added lifting function, which can avoid problems such as jamming, fixture deformation, or cracking when changing corner columns.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
