Description

Technical Field

[0001] This utility model relates to the field of inspection of suspension connecting plates, and in particular to a tensile testing device for irregularly shaped suspension connecting plates. Background Technology

[0002] Suspension couplings are made of steel plates and are widely used in transmission lines of various voltage levels. Their main function is to facilitate the conversion, connection, and load redistribution from insulator string suspension points to conductor suspension points. Different voltage levels of transmission lines have different requirements for the spacing of suspension couplings. The spacing directly affects the electrical clearance, mechanical strength, and anti-galloping performance of the line. Therefore, a reasonable spacing design can ensure the safety and stability of the line under normal operation and extreme weather conditions.

[0003] With the development of power systems, the requirements for suspension coupling plates are constantly increasing. Their performance, quality, and safety are directly related to the stable operation and safety of the entire power system. Currently, the tensile testing of suspension coupling plates typically involves fixing the coupling plate to be tested onto a tensile testing machine using bolts, followed by measurement. However, many problems exist in the fixing process. For example, the coupling plate is prone to movement during fixing, making it difficult for one person to complete the operation, resulting in high fixing difficulty and severely impacting testing efficiency. Furthermore, instability during fixing or different fixing methods can lead to deviations in test results, affecting data accuracy. Additionally, the availability of various sizes for suspension coupling plates further increases the complexity of fixing and testing, and coupling plates with different spacing can easily produce different results during testing.

[0004] Therefore, there is an urgent need to propose a tensile testing device suitable for irregularly shaped suspension plates with different joint spacings, especially a tensile testing device for irregularly shaped suspension plates with larger joint spacings. This device should be able to effectively test the mechanical properties of irregularly shaped suspension plates of different sizes, have a simple structure, be easy to operate, and ensure the accuracy of the mechanical property testing of irregularly shaped suspension plates.

Those skilled in the art should understand that the embodiments described below are only a part of the embodiments disclosed in this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] Various non-limiting embodiments of this utility model are described in detail below. Any number of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0033] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0034] Please see Figure 1-6 The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0035] A tensile testing device for an irregularly shaped suspension plate includes a control console 1, a base 2, a fixing component 3, and a tension component 4. A fixing plate 5 for fixing the left tension component 4 is provided at the left end of the base 2, and a piston rod 6 for providing tension to the right tension component 4 is provided at the right end of the base 2. The fixed end of the piston rod 6 is connected to the control console 1. The fixing component 3 is located inside the tension components 4 at both ends. The two tension components 4 are fixedly connected to the fixing components 3 on the corresponding sides. The fixing component 3 is slidably connected to the base 2. The fixing component 3 includes a fixing frame and a fixing pin 8. The fixing pin 8 and the fixing frame are used to fix the irregularly shaped suspension plate 9.

[0036] In this utility model, the tension component 4 is an L-shaped connector 10. The L-shaped connector 10 includes a horizontal rod and a vertical rod. The left L-shaped connector 10 is fixedly connected to the fixing plate 5 through the horizontal rod, and the right L-shaped connector 10 is fixedly connected to the piston rod 6 through the horizontal rod. The L-shaped connectors 10 on both sides are fixedly connected to the corresponding fixing components 3 through the vertical rod.

[0037] In this embodiment, a support leg 11 is provided at the lower end of the fixed frame, and a guide rail 12 extending to the left and right is fixed at the front and rear ends of the base 2. The support leg 11 is slidably connected to the guide rail 12. When the irregular suspension plate 9 is fixed on the fixed frame, the piston rod 6 provides a pulling force to the right-end L-shaped connector 10. The right-end L-shaped connector 10 drives the right-end fixed frame to move to the right, so that the irregular suspension plate 9 slides to the right to complete the pulling force test of the load hole 18 of the irregular suspension plate 9.

[0038] In this embodiment, the control console 1 is internally equipped with a power supply component and a controller 13. The fixed end of the piston rod 6 is fixedly connected to the power supply component. The controller 13 outputs a control program to the power supply component, causing the power supply component to provide different pulling forces to the piston rod 6. The piston rod 6 drives the right-end fixed frame to move to the right, thereby completing the testing of the mechanical properties of irregularly shaped suspension plates 9 of different sizes. (The control program is a conventional technical means in this field and will not be described in detail here.)

[0039] In this embodiment, the output end of the piston rod 6 is fitted with a guide frame 40, the output end of the piston rod 6 is slidably connected to the guide frame 40, and the bottom end of the guide frame 40 is fixedly connected to the base 2.

[0040] In this utility model, the fixing frame includes two L-shaped fixing frames 7 arranged symmetrically on the left and right. The L-shaped fixing frame 7 is divided into a vertical part and a horizontal part. The end of the vertical part of the L-shaped fixing frame 7 is provided with a vertical through hole 14. The through hole 14 is used to connect with the L-shaped connector 10. The vertical rod of the L-shaped connector 10 is inserted into the through hole 14 to ensure that the tension can be directly transmitted to the L-shaped fixing frame 7. The inner side of the vertical part of the L-shaped fixing frame 7 is provided with a sliding groove 15 extending back and forth. A slider 16 is slidably arranged inside the sliding groove 15, which is suitable for fixing irregularly shaped suspension plates 9 of different sizes. The end of the slider 16 is provided with a pin hole 17. The pin hole 17 is used to allow the fixing pin 8 to be accurately inserted into the load hole 18 of the irregularly shaped suspension plate 9 to realize the connection between the irregularly shaped suspension plate 9 and the L-shaped fixing frame 7.

[0041] In this invention, two irregularly shaped suspension plates 9 to be tested are symmetrically arranged and fixed on the fixing brackets at both ends. A short hanging plate 19 is provided between the load holes 18 at the adjacent ends of the two fixed irregularly shaped suspension plates 9. The lower end of the short hanging plate 19 is provided with a protruding post 20 for inserting into the load holes 18 at the adjacent ends of the two irregularly shaped suspension plates 9 to be tested. The distance between the protruding posts 20 is adapted to the distance between the load holes 18 at the adjacent ends of the two irregularly shaped suspension plates 9, and the size of the protruding post 20 is consistent with the size of the load holes 18 of the suspension plates. By symmetrically placing the irregularly shaped suspension plates 9, it is ensured that the two irregularly shaped suspension plates 9 remain balanced when subjected to force, thereby buffering the test deviation caused by the increased distance between the load holes 18 and improving the accuracy of the tensile test.

[0042] In this embodiment, in order to perform a tensile test on the irregular suspension plate 9, the two irregular suspension plates 9 are first placed symmetrically in a suitable position on the L-shaped fixing frame 7. Then, the fixing pin 8 is passed through the load hole 18 at the tail end of the irregular suspension plate 9 on the corresponding side to fix the irregular suspension plate 9 to the L-shaped fixing frame 7. This allows the L-shaped fixing frame 7 at the right end to move to the right along the guide rail 12 symmetrically arranged on the lower end face of the base 2 under the tensile force provided by the piston rod 6.

[0043] Example 1:

[0044] In this embodiment, each L-shaped fixing frame 7 has a mounting groove 21 on its horizontal part. A movable frame 22 is fixedly connected in the mounting groove 21. The movable frame 22 is perpendicular to the horizontal part of the L-shaped fixing frame 7. The movable frame 22 includes a guide plate 23 extending forward and backward. A slider 24 is slidably arranged in the sliding groove in the middle of the guide plate 23. The slider 24 has a pin hole 25 extending vertically for the insertion of a fixing pin 8. The fixing pin 8 is inserted into the pin hole 17, the load hole 18 and the pin hole 25. When it is necessary to fix two irregularly shaped suspension plates 9 on the L-shaped fixing frame 7, the fixing pin 8 passes through the pin hole 17, the load hole 18 and the pin hole 25 in sequence to complete the fixing of the irregularly shaped suspension plates 9.

[0045] During use, two irregularly shaped suspension plates 9 to be tested are symmetrically arranged on the L-shaped fixing frames 7 at both ends, and short hanging plates 19 are inserted to connect adjacent ends; fixing pins 8 are used at the tail end to pass through the load hole 18, pin hole 17 and pin hole 25 in sequence to fix the irregularly shaped suspension plate 9 to the L-shaped fixing frame 7; then, the controller 13 is started, and the piston rod 6 at the right end pulls the L-shaped fixing frame 7 on the right side to move to the right, observe the state of the irregularly shaped suspension plate 9, and complete the tension test of the load hole 18 of the irregularly shaped suspension plate 9.

[0046] Example 2:

[0047] In this embodiment, each L-shaped fixing frame 7 has a mounting groove 21 on its horizontal part. A movable frame 22 is fixedly connected in the mounting groove 21. The movable frame 22 is perpendicular to the horizontal part of the L-shaped fixing frame 7. The movable frame 22 includes a guide plate 23 extending forward and backward. A slider 24 is slidably arranged in the sliding groove in the middle of the guide plate 23. A pin hole 25 extending vertically is opened inside the slider 24. A fixing pin 8 is slidably connected in the pin hole 25. The fixing pin 8 moves upward and passes through the pin hole 17 and the load hole 18 of the irregular suspension plate 9 to complete the fixing of the irregular suspension plate 9.

[0048] In this embodiment, a through hole 26 is provided at the lower end of the movable frame 22 for inserting a rotating rod 41. The rotating rod 41 is rotatably connected to the movable frame 22. A bevel gear 27 is coaxially fixed on the rotating rod 41. A sleeve 28 is provided at the lower end of the fixing pin 8. The sleeve 28 is fixedly installed inside the slider 24. A threaded rod 29 is provided inside the sleeve 28. The fixed end of the threaded rod 29 extends out of the sleeve 28 and is rotatably connected to the sleeve 28. The outer side of the upper end of the threaded rod 29 is located inside the sleeve 28 and is fitted with a sliding cylinder 30. The bottom of the sliding cylinder 30 is provided with threads that are compatible with the threads on the outer periphery of the threaded rod 29. Nut 31 is fixedly connected to the bottom of slide cylinder 30. Threaded rod 29 passes through the center of the bottom of slide cylinder 30. Several keys 32 are axially arranged on the outer periphery of slide cylinder 30. Sleeve 1 28 has a keyway 33 inside that matches the keys 32 on the outer periphery of slide cylinder 30. Slide cylinder 30 and sleeve 1 28 are slidably connected up and down by keys 32 and keyways 33. The top of slide cylinder 30 is fixedly connected to the bottom of fixing pin 8. In the initial state, the top of fixing pin 8 is flush with the top of pin hole 17. A bevel gear 2 34 is fixedly connected to the outside of the fixed end of threaded rod 29. Bevel gear 1 27 and bevel gear 2 34 mesh with each other.

[0049] During use, rotating the rotating rod 41 causes the bevel gear 27 to rotate. The bevel gear 27 meshes with the bevel gear 34, causing the bevel gear 34 to rotate and drive the threaded rod 29 to rotate. The rotation of the threaded rod 29 drives the slide cylinder 30 to move upward. The slide cylinder 30 pushes the fixing pin 8 to move upward, passing through the pin hole 17 and the load hole 18 in sequence, thus completing the fixing of the irregular suspension plate 9.

[0050] In this embodiment, the rotating rod 41 is a square rod, and a sleeve 35 is fixedly provided at the end of the rotating rod 41. The sleeve 35 passes through the through hole 26 and is rotatably connected to the moving frame 22. A collar 36 is slidably provided on the rotating rod 41, and the collar 36 rotates synchronously with the rotating rod 41. A bevel gear 27 is fixedly connected to the outer circumference of the collar 36. A stop plate 37 is fixedly provided at the bottom of the slider 24. The lower end of the stop plate 37 is sleeved on the outer circumference of the collar 36 and is rotatably connected to the collar 36. The stop plate 37 is used to ensure that the bevel gear 27 and the bevel gear 34 mesh, enhance the stability of the meshing of the bevel gear 27 and the bevel gear 34, and prevent loosening or misalignment caused by vibration or external force.

[0051] In this embodiment, the outer end of the sleeve 35 is provided with a recessed hole 38, which is used to insert the handle 39 to facilitate the rotation of the rotating rod 41.

[0052] During use, two irregularly shaped suspension plates 9 to be tested are symmetrically arranged on the L-shaped fixing frames 7 at both ends, and the adjacent ends are connected by inserting short hanging plates 19. Then, the rotating rod 41 is rotated, causing the bevel gear 27 to rotate. The bevel gear 27 meshes with the bevel gear 34, causing the bevel gear 34 to rotate and drive the threaded rod 29 to rotate. The rotation of the threaded rod 29 drives the slide cylinder 30 to move upward. The slide cylinder 30 pushes the fixing pin 8 to move upward and pass through the load hole 18 of the irregularly shaped suspension plate 9, thus completing the fixation of the irregularly shaped suspension plate 9 and the L-shaped fixing frame 7. Then, the controller 13 is started, and the piston rod 6 at the right end pulls the L-shaped fixing frame 7 on the right side to move to the right. The state of the irregularly shaped suspension plate 9 is observed, and the tension test of the load hole 18 of the irregularly shaped suspension plate 9 is completed.
