Technical Field
[0001] This application relates to the technical field of impact testing, and in particular to a hammer bag type impact load testing device. Background Technology
[0002] Impact load testing equipment is a core device in the field of materials testing used to evaluate the impact resistance of materials and components. It is widely used in industrial production, engineering construction, aerospace, and many other fields, playing a crucial role, especially in the quality inspection and performance verification of sheet metal specimens and structural components. Its core principle is to simulate impact loads in actual use scenarios, transferring preset energy to the test object. By detecting parameters such as deformation and load-bearing capacity after impact, it determines whether the impact resistance meets design requirements. Traditional impact load testing equipment is mainly divided into falling weight type and pendulum type, among which the falling weight type is more commonly used in testing sheet metal specimens due to its simple structure and convenient operation. As the industry's requirements for testing accuracy, safety, and adaptability continue to increase, some devices are replacing the rigid falling weight with a special impact load bag. By filling the bag with steel balls and other weights, the impact mass is adjusted to optimize the energy release method, reduce the risk of fragmentation, and better adapt to the needs of flexible impact testing.
[0003] The existing impact load testing equipment still relies mainly on manual operation for height adjustment. When the special bag is heavy or the test requires high height accuracy, manual adjustment is not only time-consuming and laborious, but also difficult to ensure height consistency, and cannot meet the needs of repeatable testing in a short period of time. Utility Model Content
[0004] The purpose of this application is to provide a hammer bag type impact load testing device, which solves the problem that the height adjustment of traditional devices is still mainly done manually. When the special bag is heavy or the test requires high height accuracy, manual adjustment is not only time-consuming and laborious, but also difficult to ensure height consistency and cannot meet the needs of repeatable testing in a short period of time.
[0005] This application provides a hammer bag impact load testing device with the following technical solution: It includes a base plate, with casters fixedly connected to the four corners of the base plate. A support frame is fixedly connected to the upper surface of the base plate, and a fixed plate is fixedly connected between the support frame and the base plate. A top plate is fixedly connected to the top of the fixed plate. A movable pulley is provided below the top plate, and a connecting frame is rotatably connected to the outer side of the movable pulley. A hook is fixedly connected to the lower surface of the connecting frame, and a lifting ring is sleeved on the outer side of the hook. A hammer bag is fixedly connected to the lower surface of the lifting ring. The body has a positioning frame fixedly connected to the side of the fixed plate, a winding shaft rotatably connected inside the positioning frame, a lifting rope fixedly connected to the outside of the winding shaft, a hand crank rotatably connected to one side surface of the positioning frame, the hand crank fixedly connected to the winding shaft, a support plate fixedly connected to the side of the fixed plate, a motor provided above the support plate, a square shell fixedly connected to the output shaft of the motor, and a square block adapted to the square shell rotatably connected to the side surface of the positioning frame away from the hand crank, the square block fixedly connected to the winding shaft. By adopting the above technical solution, the device achieves flexible switching between automated and manual height adjustment. When adjusting the standardized test height, the square shell can be inserted into the outside of the square block, so that after the motor starts, it can drive the square block to rotate through the square shell, thereby causing the winding shaft to wind up the suspension rope, accurately adjusting the height of the bag hammer body, and stably raising the bag hammer to multiple preset standardized heights. This solves the problem that the height adjustment method of traditional devices is still mainly manual operation. When the special bag is heavy or the test requires high height accuracy, manual adjustment is not only time-consuming and laborious, but also difficult to ensure height consistency, and cannot meet the needs of repeatable testing in a short period of time. At the same time, when non-standard height testing is required, the connection between the motor and the winding shaft can be disconnected first, and then the operator can manually turn the hand crank to freely adjust the height of the bag hammer body, adapting to any non-standard testing scenario, significantly improving the applicability and flexibility of the device.
[0006] Preferably, an observation plate is fixedly connected between the support frame and the base plate, and the observation plate is made of transparent glass; By adopting the above technical solution, the observation plate made of transparent glass can not only block the fragments generated during the experiment to ensure operational safety, but also allow the operator to clearly observe the experimental process, thus balancing safety and visibility.
[0007] Preferably, a movable door is rotatably connected between the inner walls of two sides of the support frame, a limit plate is rotatably connected to one side surface of the movable door, and a limit frame adapted to the limit plate is fixedly connected to one side surface of the support frame. By adopting the above technical solution, the coordinated design of the movable door with the limiting plate and limiting frame can fix the position of the movable door.
[0008] Preferably, both ends of the side surface of the movable door away from the limiting plate are fixedly connected to side plates, and several rotating cylinders are rotatably connected between the two side plates; By adopting the above technical solution, heavier test materials can be transferred to the base plate by rotating the drum, reducing the difficulty of handling, saving labor costs, and improving the efficiency of test preparation.
[0009] Preferably, two fixed frames are fixedly connected to the upper surface of the top plate. A first fixed pulley is rotatably connected inside one of the fixed frames, and a second fixed pulley is rotatably connected to the upper surface of the other fixed frame. The lifting rope is located outside the first fixed pulley, the second fixed pulley, and the movable pulley. The end of the lifting rope away from the winding shaft is fixedly connected to the lower surface of the top plate. By adopting the above technical solution, the coordinated operation of the first fixed pulley, the second fixed pulley, and the movable pulley makes the lifting and lowering of the bag hammer body more stable and improves the accuracy of height adjustment.
[0010] Preferably, a slide rail is fixedly connected to the upper part of the support plate, a movable plate is slidably connected to the outer side of the slide rail, and the motor is located on the upper surface of the movable plate and fixedly connected to the movable plate. By adopting the above technical solution, the sliding connection design between the slide rail and the moving plate provides stable movement guidance for the motor.
[0011] Preferably, a vertical plate is fixedly connected to the upper surface of the support plate, and a threaded rod is rotatably connected to one side surface of the vertical plate. The threaded rod is located outside the movable plate and is threadedly connected to the movable plate. By adopting the above technical solution, the threaded connection structure between the threaded rod and the moving plate can control the movement distance of the motor and realize rapid switching of power connection.
[0012] In summary, this application includes at least one of the following beneficial technical effects: 1. This hammer bag impact load testing device, through the arrangement of a hand crank, motor, square block, square shell, moving plate, slide rail, and threaded rod, achieves flexible switching between automated and manual height adjustment. When adjusting the standardized test height, the threaded rod can be rotated to move the moving plate and drive the motor. After the motor moves, the square shell can enter the outside of the square block, so that after the motor starts, it can drive the square block to rotate through the square shell, thereby causing the winding shaft to wind up the suspension rope, accurately adjusting the height of the bag hammer body, and stably raising the bag hammer to multiple preset standardized heights. This solves the problem that the height adjustment method of traditional devices is still mainly manual operation. When the special bag is heavy or the test requires high height accuracy, manual adjustment is not only time-consuming and laborious, but also difficult to ensure height consistency, and cannot meet the needs of repeatable testing in a short period of time. At the same time, when non-standard height testing is required, the threaded rod can be rotated in the opposite direction to move the motor again, disconnecting the connection between the motor and the winding shaft. Then the operator can manually rotate the hand crank to freely adjust the height of the bag hammer body, adapting to any non-standard test scenario, significantly improving the applicability and flexibility of the device.
[0013] 2. This hammer bag impact load testing device, through the arrangement of a support frame, observation plate, movable door, side plate, and rotating cylinder, allows the observation plate to block the fragments generated by the collision during the test, eliminating the risk of injury from fragments. At the same time, the glass observation plate can clearly display the entire test process, facilitating real-time monitoring by operators. When moving heavier test materials to the bottom plate, the movable door can be rotated to form a ramp with the ground, and then the heavier test materials can be moved to the top of the roller. The rolling action of the rotating cylinder can easily transfer the heavy objects to the bottom plate, greatly reducing the difficulty of handling, saving labor costs, and improving the efficiency of test preparation.

Detailed Implementation
[0016] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5 This application will be described in further detail below.
[0017] Example 1: A hammer bag type impact load testing device, referring to Figure 1 , Figure 2 , Figure 3 and Figure 4The system includes a base plate 1, with casters 2 fixedly connected to the four corners of the bottom of the base plate 1. A support frame 3 is fixedly connected to the upper surface of the base plate 1. A fixed plate 10 is fixedly connected between the support frame 3 and the base plate 1. A top plate 11 is fixedly connected to the top of the fixed plate 10. A movable pulley 15 is provided below the top plate 11. A connecting frame 16 is rotatably connected to the outer side of the movable pulley 15. A hook 17 is fixedly connected to the lower surface of the connecting frame 16. A lifting ring 18 is sleeved on the outer side of the hook 17. A bag hammer body 19 is fixedly connected to the lower surface of the lifting ring 18. A positioning frame 20 is fixedly connected to the side of the fixed plate 10. A winding shaft 21 is rotatably connected inside the positioning frame 20. A lifting rope 22 is fixedly connected to the outer side of the winding shaft 21. A hand crank 23 is rotatably connected to one side surface of the positioning frame 20. A hand crank 23 is fixedly connected to a take-up shaft 21. A support plate 24 is fixedly connected to the side of a fixed plate 10. A motor 25 is located above the support plate 24. The output shaft of the motor 25 is fixedly connected to a square shell 27. A square block 26, which is compatible with the square shell 27, is rotatably connected to the side of the positioning frame 20 away from the hand crank 23. The square block 26 is fixedly connected to the take-up shaft 21. Two fixed frames 12 are fixedly connected to the upper surface of the top plate 11. A first fixed pulley 13 is rotatably connected inside one fixed frame 12, and a second fixed pulley 14 is rotatably connected to the upper surface of the other fixed frame 12. A lifting rope 22 is located outside the first fixed pulley 13, the second fixed pulley 14, and the movable pulley 15. The end of the lifting rope 22 away from the take-up shaft 21 is fixedly connected to the lower surface of the top plate 11. On the support plate 24, a slide rail 29 is fixedly connected to the top, and a movable plate 28 is slidably connected to the outside of the slide rail 29. A motor 25 is located on the upper surface of the movable plate 28 and is fixedly connected to it. A vertical plate 31 is fixedly connected to the upper surface of the support plate 24, and a threaded rod 30 is rotatably connected to one side surface of the vertical plate 31. The threaded rod 30 is located on the outside of the movable plate 28 and is threadedly connected to it. Through the arrangement of the hand crank 23, motor 25, square block 26, square shell 27, movable plate 28, slide rail 29, and threaded rod 30, the device achieves flexible switching between automated and manual height adjustment. When adjusting the standardized test height, the threaded rod 30 can be rotated to move the movable plate 28, which in turn drives the motor 25 to move. After the motor 25 moves, it can move the square shell 27 into position. The square block 26 is inserted into the outside of the square block 26, so that after the motor 25 is started, it can drive the square block 26 to rotate through the square shell 27. This causes the winding shaft 21 to wind up the hanging rope 22, precisely adjusting the height of the bag hammer body 19 and stably raising the bag hammer to multiple preset standardized heights. This solves the problem that the height adjustment method of traditional devices is still mainly manual. When the special bag is heavy or the test requires high height accuracy, manual adjustment is not only time-consuming and laborious, but also difficult to ensure height consistency, and cannot meet the needs of repeatable testing in a short period of time. At the same time, when non-standardized height testing is required, the threaded rod 30 can be rotated in the opposite direction to move the motor 25 again, disconnecting the motor 25 from the winding shaft 21. Then the operator can manually rotate the hand crank 23.The height of the bag hammer body is freely adjustable by 19mm, adapting to any non-standard testing scenario and significantly improving the device's applicability and flexibility.
[0018] Example 2: A hammer bag type impact load testing device, referring to Figure 1 and Figure 5 An observation plate 4, made of transparent glass, is fixedly connected between the support frame 3 and the base plate 1. A movable door 5 is rotatably connected between the inner walls of two sides of the support frame 3. A limit plate 6 is rotatably connected to one side surface of the movable door 5. A limit frame 7, adapted to the limit plate 6, is fixedly connected to one side surface of the support frame 3. Side plates 8 are fixedly connected to both ends of the side surface of the movable door 5 away from the limit plate 6. Several rotating cylinders 9 are rotatably connected between the two side plates 8. The support frame 3, observation plate 4, movable door 5, side plates 8, and rotating cylinders 9 are connected to the base plate 1. The design of the device allows the observation plate 4 to block debris generated during the test, eliminating the risk of injury from debris. At the same time, the glass observation plate 4 can clearly display the entire test process, facilitating real-time monitoring by operators. When moving heavier test materials to the base plate 1, the movable door 5 can be rotated to form a ramp with the ground. The heavier test materials can then be moved to the top of the roller. The rolling action of the rotating drum 9 can easily transfer the heavy objects to the base plate 1, greatly reducing the difficulty of handling, saving labor costs, and improving the efficiency of test preparation.
[0019] The implementation principle of this application embodiment is as follows: Before testing, if a standardized height test is required, first rotate the threaded rod 30. After the threaded rod 30 rotates, it will drive the moving plate 28 to move on the slide rail 29. After the moving plate 28 moves, it will cause the square shell 27 driven by the motor 25 to move, thereby moving the square shell 27 to the outside of the square block 26. Then, start the motor 25. The output shaft of the motor 25 drives the square shell 27 to rotate, thereby causing the square block 26 to drive the winding shaft 21 to rotate. When the winding shaft 21 rotates, it winds up the outer suspension rope 22. The suspension rope 22 passes through the first fixed pulley 13, the second fixed pulley 14 and the movable pulley 15 in sequence. Through the other end of the suspension rope 22 and the fixation to the lower surface of the top plate 11, the force is transmitted, thereby pulling the movable pulley 15 and the connecting frame 16 to rise. The connecting frame 16 drives the bag hammer body 19 to rise to the preset standardized height through the hook 17 and the ring 18. Then, the motor 25 is de-energized, and the bag hammer body 19 can be lowered to test the object. During non-standard height testing, the reverse rotation of the threaded rod 30 causes the moving plate 28 to drive the motor 25 to reset, separating the square shell 27 from the square block 26, disconnecting the motor 25 from the winding shaft 21. The operator manually rotates the hand crank 23, which directly drives the winding shaft 21 to rotate and retract the rope 22, thereby adjusting the bag hammer body 19 to any non-standard height. After that, simply release the hand crank 23 to conduct an impact test on the object. During the test preparation stage, when transporting heavier test materials, rotate the limiting plate 6 to separate the limiting plate 6 from the limiting frame 7. Then, rotate the movable door 5 to form a slope with the ground. Then, place the test material on the rotating drum 9, and use the rolling of the rotating drum 9 to effortlessly transfer the material to the top of the base plate 1. During the test, the transparent glass observation plate 4 between the support frame 3 and the base plate 1 can block the fragments generated by the collision, while allowing the operator to observe the test situation in real time. The casters 2 enable flexible movement of the entire device.
