[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3This utility model provides an embodiment of a reciprocating tension mechanism for fatigue performance verification of a fall arrestor component. The mechanism includes a plate frame 1, which serves as the basic load-bearing structure. Support rods 17 are fixedly connected to the inner sides of the left and right sides of the plate frame 1 to prevent instability in the support from causing deviations in the movement trajectory, thus affecting the accuracy of the fatigue performance verification of the fall arrestor component. A rotating rod 16 is rotatably connected to the outer side of the support rod 17. The rotating rod 16 slides within a groove on the inner side of the reciprocating plate 18, providing auxiliary guidance and balancing the force on the reciprocating plate 18, making the reciprocating motion of the reciprocating plate 18 smoother and reducing swaying. The reciprocating plate 18 is slidably connected to the outer side of the rotating rod 16 and is the core component for realizing the reciprocating tension action. The front side of the reciprocating plate 18 is slidably connected to the rear side of the turntable 8, further ensuring the synchronization and stability of the movement. A fixed ring 9 on the top side is used to connect the fall arrestor component, transmitting the reciprocating motion to the component to achieve fatigue performance verification. The reciprocating plate 18... A sliding rod 19 is slidably connected to the inner side of the reciprocating plate 18. The sliding rod 19 slides in the sliding groove opened on the inner side of the middle part of the reciprocating plate 18, converting the rotational motion of the turntable 8 into the linear reciprocating motion of the reciprocating plate 18. It is a key connecting component for the conversion of motion mode. The turntable 8 is fixedly connected to the outer side of the sliding rod 19. The groove opened on the top side of the base 2 guides and limits the movement of the turntable 8, ensuring the stability of its rotation process and providing a continuous and stable power source for the reciprocating motion of the reciprocating plate 18. The frame 3 is fixedly connected to the rear side of the plate frame 1, providing a solid support for the motor 4. The frame 3 also strengthens and fixes the rear structure of the entire mechanism, enhancing the overall rigidity of the mechanism. The motor 4 is fixedly connected to the top side of the frame 3. As the power source of the mechanism, its drive end is fixedly connected to the outer side of the turntable 8, which can provide continuous power for the rotation of the turntable 8. The drive end of the motor 4 is fixedly connected to the outer side of the turntable 8, and the drive end of the motor 4 is rotatably connected to the inner side of the plate frame 1.

[0034] Reference Figures 4-5Each of the left top sides of the frame 1 is fixedly connected to a baffle 5. The baffle 5 provides protection for the rotating shaft 15 and the connected adjusting arm 6, preventing external factors from interfering with their normal movement and ensuring the installation stability of the adjustment structure. The rotating shaft 15 is rotatably connected to the inner side of the baffle 5. It is the key component for the rotation adjustment of the adjusting arm 6. Through its rotation, it can drive the adjusting arm 6 to change its angle, thereby adjusting the position and angle of the clamp 7, so that the clamp 7 can better adapt to the fall arrestor components of different specifications and testing requirements. The adjusting arm 6 is rotatably connected to the outer side of the middle end of the rotating shaft 15, thereby driving the adjusting plate 13 and the clamp 7 to move through the adjusting rod 12. It plays the role of transmitting the adjustment action and changing the position of the clamp 7. It is an important intermediate connecting component for realizing the position adjustment of the clamp 7. The adjusting rod 12 is rotatably connected to the top side of the adjusting arm 6. The length of the adjusting rod 12 and the connection The design allows for more precise and flexible adjustment of the clamping plate 7. An adjusting plate 13 is rotatably connected to the outer side of the middle end of the adjusting rod 12. Driven by the adjusting rod 12, the adjusting plate 13 can rotate at an angle, thereby adjusting the position and angle of the clamping plate 7. This ensures that the clamping plate 7 can accurately and firmly clamp the fall arrestor components, meeting the needs of different test points. The clamping plate 7 is fixedly connected to the top side of the adjusting plate 13. Together with the clamp ear 14 and the threaded adjusting shaft 10, it can firmly clamp fall arrestor components of different thicknesses and shapes, ensuring that the components will not loosen during reciprocating tension and ensuring the smooth progress of the test. The clamp ear 14 is fixedly connected to the left side of the clamping plate 7. Through cooperation with the threaded adjusting shaft 10, the clamping force of the clamping plate 7 can be adjusted. When the dial 11 is rotated to make the threaded adjusting shaft 10 rotate, the threaded adjusting shaft 10 will move within the clamp ear 14, thereby pushing the clamping plate 7 to clamp or loosen the components.

[0035] Reference Figures 1-4The inner side of the clamping ear 14 is threadedly connected to a threaded adjusting shaft 10, which can move axially to push the clamping plate 7 to clamp or loosen the fall arrestor components. The operation is simple and convenient, and it can quickly adapt to components of different thicknesses. A dial 11 is fixedly connected to the top side of the threaded adjusting shaft 10, thereby adjusting the clamping state of the clamping plate 7. Its design increases the operating lever arm, making the adjustment process more labor-saving and efficient. Grooves are opened on the inner sides of the left and right parts of the reciprocating plate 18, and the outer side of the rotating rod 16 is rotatably connected to the inner side of the groove. A sliding groove is opened on the inner side of the middle part of the reciprocating plate 18, and the outer side of the sliding rod 19 is slidably connected to the inner side of the sliding groove. The bottom side of the plate frame 1 is fixed. The frame 3 is fixedly connected to the inner side of the base 2 and connected to the top side of the base 2. The top side of the base 2 has a groove. The base 2 serves as the bottom support structure of the entire mechanism, providing a stable installation platform for components such as the plate frame 1 and the frame 3, thereby enhancing the overall stability of the mechanism. The turntable 8 is rotatably connected to the inner side of the groove, and the reciprocating plate 18 is slidably connected to the inner side of the groove. The front side of the reciprocating plate 18 is slidably connected to the rear side of the turntable 8. A fixing ring 9 is fixedly connected to the top side of the reciprocating plate 18. When the reciprocating plate 18 makes a reciprocating motion, the fixing ring 9 will drive the component to stretch and retract, simulating the force situation of the component in actual use. It is a key connection structure that transmits the reciprocating motion to the fall arrestor component.

[0036] Working Principle: First, the motor 4, as the power source of the entire mechanism, starts working. Its drive end drives the turntable 8 to rotate stably in the groove on the top side of the base 2, providing initial power for subsequent motion transmission. Then, the sliding rod 19 fixed on the outer side of the turntable 8 cooperates with the sliding groove on the inner side of the middle of the reciprocating plate 18. During the rotation of the turntable 8, the rotational motion is converted into the linear reciprocating motion of the reciprocating plate 18 along the groove of the base 2, realizing the key transformation of motion form. At the same time, the rotating rods 16 in the inner grooves on the left and right sides of the reciprocating plate 18 rotate on the outside of the support rod 17. The synergistic effect of these components provides auxiliary guidance and balances the force for the movement of the reciprocating plate 18, effectively avoiding swaying during the movement and ensuring smoother reciprocating motion.

[0037] Subsequently, the rotating shaft 15 on the inner side of the top baffle 5 on the left side of the plate frame 1 drives the adjusting arm 6 to rotate. The adjusting rod 12 on the top side of the adjusting arm 6 is then linked with the adjusting plate 13, so that the clamping plate 7 on the top side of the adjusting plate 13 is adjusted to a position that matches the fall arrestor component. Then, the dial 11 is rotated to move the threaded adjusting shaft 10 on the inner side of the clamping ear 14, thereby firmly clamping one end of the fall arrestor component. The other end of the fall arrestor component is connected to the fixing ring 9 on the top side of the reciprocating plate 18, completing the installation and fixing of the component. Finally, as the reciprocating plate 18 continues to perform linear reciprocating motion, it drives the fall arrestor component to reciprocate and stretch through the fixing ring 9.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
