[0024] To make the objectives, technical solutions and advantages of the present application clearer and more understandable, the following further elaborates on the present application in detail with reference to specific embodiments and the accompanying drawings.

[0025] It should be noted that unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should have the ordinary meanings understood by those of ordinary skill in the field to which the present application belongs. The "first", "second" and similar terms used in the embodiments of the present application do not indicate any order, quantity or importance, but are only used to distinguish different components. The terms such as "including" or "comprising" mean that the elements or objects appearing before this term cover the elements or objects listed after this term and their equivalents, without excluding other elements or objects. The terms such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. The terms such as "upper", "lower", "left" and "right" are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0026] To facilitate the understanding of the technical solutions of the present disclosure, some technical terms related to the present disclosure are introduced below.

[0027] Static load: The maximum force that the pylon hook bears in a static or low-speed state, usually including the weight of the suspended object and the static force during flight.

[0028] Static test: By applying a force exceeding the design load, verify the strength and durability of the hook.

[0029] To make the technical solutions of the present disclosure clearer and easier to understand, the static load test device for the airborne pylon hook provided in the embodiments of the present disclosure is described in detail below with reference to the accompanying drawings.

[0030] As described in the background art section, in the static test, a tensile testing machine is required to examine a specified stress position of a hook of an airborne pylon, and it is required to conform to the actual use environment of the hook of the airborne pylon. The working principle of the existing tensile testing machine is to drive the upper and lower clamps to move through a servo motor, so as to apply a load to the product under test. Therefore, the applicant found that in the prior art, it is impossible to directly apply a static load to a specified position for a static load test.

[0031] Among them, the static load of the hook of the airborne pylon is a key parameter in the design, and strict tests are required to ensure its reliability and safety under various conditions. Specifically, the hook of the airborne pylon needs to have sufficient strength to withstand the maximum static load to avoid fracture or deformation. Therefore, it is necessary to conduct a static load test on the hook of the pylon to ensure the safe use of the hook.

[0032] In view of this, the embodiment of the present application provides a static load test device for a hook of an airborne pylon, including: a first connecting member (1), a second connecting member (2), and a locking member (201); the first connecting member (1) includes a connecting portion (101); the second connecting member (2) is detachably coupled to the first connecting member (1); the locking member (201) is rotatably coupled to the second connecting member (2) and is adapted to switch between an unlocking position and a locking position. The locking member (201) includes a limiting groove (202). When the locking member (201) is in the unlocking position, the connecting portion (101) is inserted into the limiting groove (202) to limit the first connecting member (1) and the second connecting member (2). When the locking member (201) is in the unlocking position, the connecting portion (101) is separated from the limiting groove (202) to allow the first connecting member (1) to be separated from the second connecting member (2). Through the cooperation of the connecting portion (101) of the first connecting member (1) and the locking member (201) coupled to the second connecting member (2), the hook of the airborne pylon (5) is fixed, so that the first connecting member (1) and the second connecting member (2) are axially concentric, thereby ensuring the loading direction of the load. The principle of the present application will be described in detail below Figures 1 to 3 to describe the principle of the present application in detail.

[0033] Figure 1 This is a front view structural schematic diagram of a static load test device for a hook of an airborne pylon provided by an embodiment of the present application. As Figures 1-3 shown, the static load test device for the hook of the airborne pylon includes:

[0034] a first connecting member (1), a second connecting member (2), and a locking member (201);

[0035] the first connecting member (1) includes a connecting portion (101);

[0036] The second connecting member (2) is detachably coupled to the first connecting member (1);

[0037] The locking member (201) is rotatably coupled to the second connecting member (2) and is adapted to switch between an unlocked position and a locked position. The locking member (201) includes a limiting groove (202). When the locking member (201) is in the unlocked position, the connecting portion (101) is inserted into the limiting groove (202) to limit the first connecting member (1) and the second connecting member (2). When the locking member (201) is in the unlocked position, the connecting portion (101) is separated from the limiting groove (202) to allow the first connecting member (1) to be separated from the second connecting member (2).

[0038] Therefore, in this solution, through the cooperation of the connecting portion (101) of the first connecting member (1) and the locking member (201) coupled to the second connecting member (2), the aircraft-mounted pylon hook (5) is fixed, so that the first connecting member (1) and the second connecting member (2) are axially concentric, thereby ensuring the loading direction of the load.

[0039] Exemplarily, the second connecting member (2) can be conveniently detachably coupled to the first connecting member (1), thereby improving the flexibility and adaptability of the system, enabling the user to quickly assemble or disassemble the device according to actual needs without using complex tools or performing cumbersome operation steps.

[0040] In some embodiments, first limiting holes (102) and second limiting holes (103) are oppositely arranged on both sides of the connecting portion (101) for fixing the aircraft-mounted pylon hook (5). The aircraft-mounted pylon hook (5) is provided with connecting holes (501) corresponding to the limiting holes.

[0041] Specifically, when the first limiting holes (102) and the second limiting holes (103) are correspondingly arranged with the connecting holes (501) of the aircraft-mounted pylon hook (5), the connecting pin sequentially passes through the first limiting hole (102), the connecting hole (501), and the second limiting hole (103) to fix the aircraft-mounted pylon hook (5).

[0042] Exemplarily, as Figure 1 shown, the corresponding arrangement of the first limiting holes (102) and the second limiting holes (103) with the connecting holes (501) of the aircraft-mounted pylon hook (5) can be to arrange the connecting holes (501) of the aircraft-mounted pylon hook (5) between the first limiting hole (102) and the second limiting hole (103).

[0043] Exemplarily, the diameters of the first limiting hole (102) and the second limiting hole (103) match the diameter of the connection hole (501) of the hook of the airborne pylon (5). When the connection hole (501) of the hook of the airborne pylon (5) is disposed between the first limiting hole (102) and the second limiting hole (103), the connection part (101) of the hook of the airborne pylon (5) and the first connecting member (1) is connected by a connecting pin, so as to ensure that during the static load test, the connecting pin can ensure that the hook of the airborne pylon (5) is firmly fixed at a predetermined position, avoiding position deviation or structural failure caused by external loading.

[0044] In some embodiments, the penetrating direction of the connecting pin is not limited. It may penetrate from the side of the first limiting hole (102) away from the connection hole (501), sequentially penetrate through the first limiting hole (102), the connection hole (501), the second limiting hole (103), and penetrate out from the side of the second limiting hole (103) away from the connection hole (501). It may also penetrate from the side of the second limiting hole (103) away from the connection hole (501), sequentially penetrate through the second limiting hole (103), the connection hole (501), the first limiting hole (102), and penetrate out from the side of the first limiting hole (102) away from the connection hole (501). The present application does not make specific limitations thereto.

[0045] In some embodiments, nuts are provided at both ends of the connecting pin. By tightening the nuts, the connection part (101) and the hook of the airborne pylon (5) can be effectively locked firmly together, thereby realizing the fixation of the connection part (101) and the hook of the airborne pylon (5). On the one hand, the additional fastening force provided by the nuts can ensure that even under high load conditions, the connecting pin will not slip out due to loosening, greatly enhancing the stability and safety of the entire system; on the other hand, the flexibility of adjusting the fastening degree by using nuts enables the device to adapt to connection parts (101) and pylon hooks of different thicknesses or materials, improving the versatility and application range of the device. In addition, this adjustability also facilitates quick adjustment and disassembly during the test, simplifies the maintenance process, and improves work efficiency. It can be seen that by providing nuts at both ends of the connecting pin, not only the fixation effect of the connection part (101) and the hook of the airborne pylon (5) is strengthened, but also the reliability and practicality of the entire static load test device are improved.

[0046] In addition, nuts are used on both sides of the connection part (101) to restrict the left-right relative position of the hook of the airborne pylon (5) and the connection part (101), ensuring the transmission and application of the tensile load during the static load test.

[0047] In some embodiments, the limiting groove (202) is arranged in a concave shape, and the connection parts of both sides of the limiting groove (202) and the second connecting piece (2) are arranged in a hollowed-out manner. The edges connecting both sides of the limiting groove (202) are provided with grooves for supporting the hook of the airborne mounting rack (5).

[0048] Furthermore, the locking piece (201) can be freely switched between an unlocking position and a locking position to meet different usage requirements. The locking piece (201) is specially provided with a limiting groove (202), so as to enhance the safety and stability of the connection by using mechanical principles. When the locking piece (201) is in the locking position, the connecting part (101) on the first connecting piece (1) will accurately insert into the limiting groove (202) of the locking piece (201), thereby effectively restricting the relative movement between the first connecting piece (1) and the second connecting piece (2), ensuring that the two are closely connected and not prone to accidental loosening or detachment. This not only ensures the stability of the equipment during use, but also significantly improves the reliability of the overall structure.

[0049] In some alternative embodiments, the connecting part (101) of the static load test device of the hook of the airborne mounting rack (5) is arranged in a concave shape. In some aspects, the concave shape design provides a clear spatial positioning area for other components, facilitating insertion, clamping or limiting operations. For example, in the locked state, the limiting groove (202) of the locking piece (201) can accurately embed into the opening area of the concave-shaped connecting part (101), thereby forming a physical constraint. In addition, due to the existence of the two side walls of the concave-shaped structure, it can provide additional supporting force in the vertical direction, effectively resisting the shear stress under the action of external loads, and preventing the connection point from loosening or failing due to excessive force. Moreover, the inner edge of the concave shape can serve as a natural limiting boundary to prevent slipping or detachment during the connection process, further improving the reliability of the overall connection.

[0050] In some embodiments, as Figure 2 shown, a concave part corresponding to the shape of the hook of the airborne mounting rack (5) is provided at the bottom of the limiting groove (202) for cooperating with the hook of the airborne mounting rack (5) to clamp the hook of the airborne mounting rack (5).

[0051] In some embodiments, as Figures 1-3 shown, the first connecting piece (1) is funnel-shaped. The large-size end of the first connecting piece (1) is provided with the connecting part (101), and the small-size end of the first connecting piece (1) is used for clamping by the clamping device. Among them, the small-size end of the first connecting piece (1) is arranged in a cylindrical shape.

[0052] Exemplarily, the upper connecting device is used to fixedly restrain the inclined plane of the hook (5) of the airborne pylon, and balance the overturning moment generated by the hook (5) of the airborne pylon during the transfer of the tensile load. Specifically, the setting of the connecting portion (101) ensures that even under high load conditions, any possible overturning trend can be effectively balanced and controlled. This can not only maximize the contact area, reduce the local stress concentration phenomenon, but also prevent the hook from overturning due to uneven force by evenly distributing the load applied to the hook.

[0053] In some alternative embodiments, the small-sized end of the first connecting member (1) may be set to other shapes that are convenient for clamping, and the present application does not make specific limitations thereto.

[0054] In some embodiments, as Figures 1-3 shown, the second connecting member (2) is funnel-shaped, the large-sized end of the second connecting member (2) is provided with the limiting groove (202), and the small-sized end of the second connecting member is used for the clamping device to clamp. Among them, the small-sized end of the second connecting member (2) is set to be cylindrical.

[0055] In some alternative embodiments, the small-sized end of the second connecting member (2) may be set to other shapes that are convenient for clamping, and the present application does not make specific limitations thereto.

[0056] In some embodiments, the first connecting member (1) and the second connecting member (2) are axially concentrically arranged, so as to ensure the consistency of the load application direction.

[0057] Exemplarily, the design of the lower connecting device aims to accurately fix the specified force-bearing position of the hook (5) of the airborne pylon, and it adopts a unique groove shape to achieve this goal. This groove-shaped design can not only ensure that the externally applied load accurately acts on the predetermined area, thereby avoiding structural damage or test result deviation caused by uneven load distribution, but also effectively restrains the left-right relative position of the hook (5) of the airborne pylon through the special design of the middle opening. Specifically, the opening design provides a clear space limit for the pylon hook, preventing the possible lateral displacement during the loading process and ensuring the stability and reliability of the entire system.

[0058] In addition, by ensuring that the upper connecting device and the lower connecting device are axially concentric, the load can be applied along the expected direction, avoiding the generation of lateral forces and the possible additional stress concentration problems caused by them. The precise load guidance not only improves the accuracy of the test data, but also extends the service life of the device under test, reducing the risk of wear and damage caused by improper loading.

[0059] It can be seen that the groove-shaped design enhances the support for specific stress points, enabling the structure to maintain its integrity even under high-load conditions. Secondly, by precisely controlling the load direction, unnecessary energy losses are reduced, and potential safety hazards are minimized. The avoidance design at the middle opening simplifies the installation process, allowing operators to more quickly and accurately complete the positioning and fixing of the hanger hook. Moreover, it can be applied to airborne hanger hooks (5) of different types and specifications to meet diverse requirements.

[0060] As can be seen from the above, an airborne hanger hook static load test device provided by the present application includes: a first connecting member, a second connecting member, and a locking member; the first connecting member includes a connecting portion; the second connecting member is detachably coupled to the first connecting member; the locking member is rotatably coupled to the second connecting member and is adapted to switch between an unlocked position and a locked position. The locking member includes a limiting groove. When the locking member is in the unlocked position, the connecting portion is inserted into the limiting groove to limit the first connecting member and the second connecting member. When the locking member is in the unlocked position, the connecting portion is separated from the limiting groove to allow the first connecting member and the second connecting member to be separated. Through the cooperation of the connecting portion of the first connecting member and the locking member coupled to the second connecting member, the airborne hanger hook is fixed, making the first connecting member and the second connecting member axially concentric, thereby ensuring the load application direction.
