Description

Technical Field

[0001] This application relates to the field of drop weight testing technology, and more specifically, to a drop weight testing machine. Background Technology

[0002] The drop hammer impact tester is suitable for determining the impact resistance of various pipes (PVC-U water supply pipes, sewage pipes, low-pressure water supply pipes, low-pressure water transmission pipes, core layer foamed pipes, double-wall corrugated pipes, PE water supply pipes) and sheets, and is also suitable for rigid plastic sheets.

[0003] Existing drop hammer testing machines have low overall practicality because they can only be designed and used for a single type of test sample. Therefore, if you want to change to other types of test samples, they cannot be used, resulting in problems that cannot meet current technical requirements and process specifications.

[0004] To address the aforementioned issues, this application provides a drop hammer testing machine. Utility Model Content

[0005] The drop weight testing machine provided in this application adopts the following technical solution:

[0006] A drop weight test machine includes a frame, an auxiliary mechanism inside the frame, and the auxiliary mechanism extending to the outside of the frame.

[0007] The auxiliary mechanism includes an upper fixture and a lower fixture, both located inside a frame. The upper fixture is located on top of the lower fixture, and two fixed brackets are fixedly connected to the top of the lower fixture. The two fixed brackets are symmetrically arranged around the center line of the lower fixture. Each of the two fixed brackets has a groove inside, and a sliding plate is embedded in the groove. A groove is formed on the top of the lower fixture, and a memory spring is fixedly embedded in the groove. The memory spring is fixedly connected to the bottom of the sliding plate. Two toothed plates are fixedly connected to the top of the sliding plate, and gears mesh on the rear side of each of the two toothed plates. A screw is fixedly embedded inside each of the two gears, and threaded sleeves are screwed onto the outer walls of each of the two screws. The inner ends of each threaded sleeve extend to the space between the two fixed brackets and are fixedly connected to a fixing clamp. A pipe is provided between the two fixing clamps, and a connecting component is provided on the outside of the pipe.

[0008] Furthermore, the two toothed plates are located on the outside of the two fixing frames, and both fixing clips are made of anti-slip material.

[0009] With the above technical solution, since both fixing clips are made of non-slip material, the friction between the two fixing clips and the pipe can be enhanced, thereby making the pipe more securely fixed.

[0010] Furthermore, the connecting component includes four limiting blocks, which are respectively fixedly connected to the outside of the two threaded sleeves and embedded inside the two fixing frames.

[0011] The above technical solution, by setting four limit blocks, can limit the movement of the two threaded sleeves, thereby making the movement of the two threaded sleeves towards or away from each other more stable.

[0012] Furthermore, the four limiting blocks are symmetrically arranged in pairs with the center lines of the two threaded sleeves as axes, and a positioning pad is provided at the top of the pipe.

[0013] The above technical solution allows for secondary fixation of the pipeline by setting up positioning pads.

[0014] Furthermore, the positioning pad is tightly fitted to the pipe and is fixedly connected to the bottom of the upper fixture.

[0015] Furthermore, an electric push rod and a sleeve rod are installed on the top of the upper fixture, and a slider rail is sleeved on the outside of the electric push rod and the sleeve rod, and the slider rail is installed and connected to the frame.

[0016] The above technical solution, by setting a slider track, can limit the upper fixture, thereby ensuring that the upper fixture remains vertical when moving up and down.

[0017] Furthermore, a drop hammer is provided inside the sleeve rod, and a high-frequency linear motor is installed on the outside of the sleeve rod, with the high-frequency linear motor being installed and connected to the frame.

[0018] The above technical solution, by setting a high-frequency linear motor, makes it easier to drive the sleeve upward in the later stage.

[0019] In summary, this application includes the following beneficial technical effects:

[0020] The pipe can be placed on top of the slide plate first. Then the pipe will press the slide plate downward, causing the slide plate to move downward. At this time, the memory spring is in a compressed state, and the two toothed plates will move downward accordingly. Since the two toothed plates mesh with two gears respectively, the two gears will rotate, causing the two threaded sleeves to drive the two fixing clamps to move towards each other, clamping and fixing the pipe from both sides. Through the above structure, not only is the manufacturing and use cost of the equipment reduced, but it can also be used for pipes of various diameters, thereby achieving the effect of meeting current technical requirements and process specifications.

[0031] Example:

[0032] This application discloses a drop weight testing machine; please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 It includes a frame 1, an auxiliary mechanism inside the frame 1, and the auxiliary mechanism extends to the outside of the frame 1;

[0033] The auxiliary mechanism includes an upper fixture 2 and a lower fixture 3, both of which are located inside the frame 1. The upper fixture 2 is located on top of the lower fixture 3. Two fixed brackets 4 are fixedly connected to the top of the lower fixture 3. The two fixed brackets 4 are arranged symmetrically about the center line of the lower fixture 3. Each of the two fixed brackets 4 has a groove inside, and a sliding plate 5 is embedded in the groove. The top of the lower fixture 3 has a groove, and a memory spring 6 is fixedly embedded in the groove. The memory spring 6 is fixedly connected to the bottom of the sliding plate 5. Two toothed plates 7 are fixedly connected to the top of the sliding plate 5. Gears 8 are meshed on the rear side of each of the two toothed plates 7. Screws 9 are fixedly embedded inside each of the two gears 8. Threaded sleeves 10 are screwed onto the outer wall of each of the two screws 9. The inner ends of each threaded sleeve 10 extend to the space between the two fixed brackets 4 and are fixedly connected to a fixing clamp 11. A pipe 12 is provided between the two fixing clamps 11.

[0034] Please see Figure 3 and Figure 4 The pipe 12 is provided with connecting parts on the outside. Two toothed plates 7 are located on the outside of the two fixing brackets 4 respectively. Both fixing clips 11 are made of anti-slip material. Since both fixing clips 11 are made of anti-slip material, the friction between the two fixing clips 11 and the pipe 12 can be strengthened, so that the pipe 12 can be fixed more firmly.

[0035] Please see Figure 4 The connecting component includes four limiting blocks 13. The four limiting blocks 13 are respectively fixedly connected to the outside of the two threaded sleeves 10 and embedded in the two fixing frames 4. By setting the four limiting blocks 13, the two threaded sleeves 10 can be limited, so that the two threaded sleeves 10 can move towards each other or in opposite directions more smoothly.

[0036] Please see Figure 2 and Figure 4 Four limiting blocks 13 are symmetrically arranged in pairs with the center lines of the two threaded sleeves 10 as the axis. A positioning soft pad 14 is provided on the top of the pipe 12. The positioning soft pad 14 is tightly attached to the pipe 12. The positioning soft pad 14 is fixedly connected to the bottom of the upper fixture 2. By setting the positioning soft pad 14, the pipe 12 can be further fixed.

[0037] Please see Figure 1The upper fixture 2 is equipped with an electric push rod 15 and a sleeve rod 16. A slider rail 17 is fitted on the outside of the electric push rod 15 and the sleeve rod 16. The slider rail 17 is installed and connected to the frame 1. A drop hammer 18 is provided inside the sleeve rod 16. A high-frequency linear motor 19 is installed on the outside of the sleeve rod 16. The high-frequency linear motor 19 is installed and connected to the frame 1. By setting the slider rail 17, the upper fixture 2 can be limited, so that the upper fixture 2 can maintain a vertical state when moving up and down. At the same time, by setting the high-frequency linear motor 19, it is convenient to drive the sleeve to move upward later.

[0038] The implementation principle of this embodiment is as follows: Before use, the high-frequency linear motor 19 can be started first to raise the sleeve rod 16 and the drop hammer 18 to the specified height. Then, the electric push rod 15 is started, and the upper fixture 2 is raised through the telescopic end of the electric push rod 15. When the upper fixture 2 raises the positioning soft pad 14 to the appropriate height, the pipe 12 can be placed on the top of the slide plate 5. Then, the pipe 12 will press the slide plate 5 downward, causing the slide plate 5 to move downward. At this time, the memory spring 6 will be stressed, deformed, and in a compressed state. Here, the elastic force of the memory spring 6 is less than the weight of all pipes 12 of different specifications. At the same time, the two toothed plates 7 will move downward. Since the two toothed plates 7 are respectively engaged with the two gears 8, the two gears 8 will rotate. Each limiting block 13 is matched with one of the two fixing brackets 4, thus limiting the two threaded sleeves 10. This causes the two threaded sleeves 10 to drive the two fixing clamps 11 to move towards each other, clamping and fixing the pipe 12 from both sides. After the pipe 12 is fixed, the electric push rod 15 can be activated again. Similarly, the upper fixture 2 drives the positioning pad 14 to move downward, fixing the pipe 12 again from the top. Finally, the drop hammer 18 will use its own weight to collide with the pipe 12 to detect whether the pipe 12 is broken. Through the above structure, not only is the manufacturing and use cost of the equipment reduced, but it can also be used for pipes 12 of various diameters, thereby achieving the effect of meeting current technical requirements and process specifications.

[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
