Description

Technical Field

[0001] This utility model relates to the field of test pile production technology, specifically to a noise reduction mechanism for a press used in test pile production. Background Technology

[0002] A test pile production press is a specialized piece of equipment used to manufacture and test test piles. Its main purpose is to perform pressure tests on the test piles to ensure they meet relevant quality standards and safety requirements. This equipment typically features a high-precision pressure control system capable of simulating the pressure environment of actual use, thereby evaluating the load-bearing capacity and durability of the test piles.

[0003] Existing test piles require the use of equipment such as presses during production and testing. Workers exposed to the high-intensity noise (typically 90-110 dB) generated by these presses for extended periods can suffer damage to cochlear sensory cells, initially manifesting as high-frequency hearing loss, and potentially progressing to permanent deafness. Furthermore, noise levels exceeding 75 dB(A) may trigger high blood pressure, arrhythmias, and lipid metabolism disorders. Studies have shown a significantly increased incidence of cardiovascular disease among workers with long-term exposure to press noise; therefore, we need to propose a noise reduction mechanism for presses used in test pile production.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a noise reduction mechanism for a pressure machine used in the production of test piles, comprising a base plate 1. The base plate 1 has a pressure mechanism on its top for the production and testing of test piles. The pressure mechanism includes a placement platform 2, which is positioned on top of the base plate 1. A workbench 3 is located on top of the placement platform 2. A support 4 is positioned above the placement platform 2. A mounting plate 5 is located on top of the support 4. A servo cylinder 6 is located on top of the mounting plate 5. A pressure plate 7 is installed through the output end of the servo cylinder 6, passing through the mounting plate 5. The test pile is placed on the workbench 3, and the servo cylinder 6 applies pressure through the pressure plate 7 to simulate actual working conditions and test the pile's bearing capacity. The pressure parameters of the servo cylinder 6 are precisely adjusted by a controller to ensure the reliability of the test data.

[0022] The top of the base plate 1 is provided with an isolation mechanism to isolate the pressure mechanism from the external environment to reduce noise; the isolation mechanism includes a first housing 8, which is disposed on the top of the base plate 1, and a second housing 9, which is disposed inside the first housing 8. The first housing 8 and the second housing 9 form a double-layer sound insulation cavity, which blocks the transmission of mechanical vibration through the sound insulation plate 11.

[0023] The inner wall of the isolation mechanism is equipped with a sound-absorbing mechanism for internal sound wave reflection; the sound-absorbing mechanism includes sound-absorbing cotton 10, which is disposed on the inner wall of the second outer shell 9, and a sound insulation plate 11 is disposed between the first outer shell 8 and the second outer shell 9. The sound-absorbing cotton 10 and the sound insulation plate 11 absorb high-frequency noise such as metallic impact sound, reducing the noise from 110dB to below 75dB.

[0024] The isolation mechanism is equipped with an opening and closing mechanism at its top for inserting the pressure mechanism. This mechanism includes a top plate 12 positioned above the first housing 8. A dovetail block 13 is located on the top of the first housing 8. A dovetail groove 14 is formed at the bottom of the top plate 12 and fits into the dovetail block 13. A bolt 15 is located on the top of the top plate 12, threaded through the top plate 12 and connected to the first housing 8. The top plate 12 can be quickly assembled and disassembled via the dovetail groove 14 and bolt 15, facilitating equipment maintenance.

[0025] The top of the base plate 1 is equipped with a buffer mechanism to absorb the pressure generated by the pressure-absorbing mechanism. The buffer mechanism includes a buffer pad 16, which is located on the top of the base plate 1 and at the bottom of the placement platform 2. The bottom of the placement platform 2 has a placement groove 17. The top of the base plate 1 is equipped with an electric guide rail 18, and a support block 19 is provided on one side of the electric guide rail 18. The support block 19 is adapted to the placement groove 17. The buffer pad 16 absorbs pressure impacts and reduces equipment resonance. The electric guide rail 18 moves the support block 19, facilitating the replacement of the buffer pad 16.

[0026] The isolation mechanism has an insertion mechanism for inserting test piles. This insertion mechanism includes a soundproof door 20, which is located on and penetrates the surface of the first housing 8. A metal hinge 21 is provided on the outer wall of the first housing 8 and connected to the soundproof door 20. A handle 22 is provided on the surface of the soundproof door 20, and a locking block 23 is provided on the surface of the first housing 8, which is compatible with the handle 22. The soundproof door 20 achieves airtight closure through the locking block 23 and the metal hinge 21, blocking sound wave leakage. After the test pile is inserted through the soundproof door 20, the system automatically starts the pressure test process without any manual intervention.

[0027] A controller is installed on the surface of the base plate 1, and the controller is electrically connected to the servo cylinder 6 and the electric guide rail 18.
