Description

Technical Field

[0001] This utility model relates to the field of mechanical testing device technology, specifically a mechanical testing device for green high-performance concrete. Background Technology

[0002] Green high-performance concrete is a type of high-performance concrete that uses low-silicate cement clinker powder as a binder and makes full use of industrial solid waste and low-quality natural resources as raw materials. It can utilize solid waste and reduce cement usage to achieve the goal of environmental protection. Since the raw materials for the production of green high-performance concrete are not the same, it is necessary to test different types or batches of concrete using a mechanical testing device for green high-performance concrete.

[0003] The mechanical testing device for green high-performance concrete supports the concrete sample on the testing platform. The height of the pressing mechanism is adjusted by the adjusting mechanism, and pressure is applied to the concrete sample for testing. Some existing mechanical testing devices for green high-performance concrete lack dust removal functions. During the testing process, the broken concrete sample will generate dust. Dust will be scattered during the testing process and when cleaning the concrete sample after the test. After each test, the staff needs to clean up the scattered dust, which is time-consuming and labor-intensive. Therefore, a mechanical testing device for green high-performance concrete is proposed to address the above problems. Summary of the Invention

The material receiving mechanism 5 includes a limiting frame 51 fixedly connected to the lower side of the workbench 11. A material receiving box 52 located directly below the groove in the middle of the workbench 11 is slidably connected to the inner side of the limiting frame 51.

[0017] A mounting bracket 12 is fixedly connected to the upper side of the workbench 11, and a first electric push rod 13 is fixedly connected to the lower side of the mounting bracket 12. A pressing mechanism 14 is fixedly connected to the lower side of the first electric push rod 13, and a pressing plate 15 located directly above the groove in the middle of the workbench 11 is fixedly connected to the lower side of the pressing mechanism 14. The pressing mechanism 14 is driven to move downward by the first electric push rod 13, and pressure is applied to the green high-performance concrete sample by the pressing mechanism 14, so that mechanical testing can be performed. The right-side latch of the rotating door 32 can be locked with the right-side latch of the protective frame 31. The support frame 21 is a rectangular frame, and the height of the protective frame 31 and the rotating door 32 are the same. The protective frame 31 and the rotating door 32 can form a rectangular frame with a length and width equal to the length and width of the support frame 21, respectively. The protective frame 31 and the rotating door 32 can prevent broken concrete blocks from splashing out. The protective frame 31 is provided with uniform The dust collection box 41 has a circular opening, and the side of the dust collection box 41 that contacts the protective frame 31 has a suction port corresponding to the opening of the protective frame 31. The dust collection box 41 is a "U" shaped box. The curved surface of the ground inside the dust collection box 41 is evacuated by the air pump 44 to create a negative pressure inside the dust collection box 41, so that the small particles of broken concrete and dust can be collected through the dust collection box 41. The front side of the third electric push rod 33 is aligned with the front side of the protective frame 31. There is a certain gap between the lower end of the push plate 34 and the detection table 24. The lower bristles of the soft brush 35 are in contact with the detection table 24. The upper side of the receiving box 52 is attached to the lower side of the workbench 11. The push plate 34 can push the concrete fragments on the detection table 24 backward, so that the concrete fragments fall into the receiving box 52. The soft brush 35 can sweep the detection table 24 to remove the concrete fragments adhering to the detection table 24.

[0018] Workflow: Before use, fix the workbench 11 in a suitable position and connect the power supply. This device is equipped with an external controller, which is electrically connected to the first electric push rod 13, the pressing mechanism 14, the second electric push rod 22, the third electric push rod 33, and the gas pump 44. Manually operating the external controller can adjust the operating status of the first electric push rod 13, the pressing mechanism 14, the second electric push rod 22, the third electric push rod 33, and the gas pump 44 respectively. All of the above are existing technologies. When using the device, the operator first opens the rotating door 32, places the green high-performance concrete sample to be tested on the testing table 24, and closes the rotating door 32. Then, the operator starts the first electric push rod 13 through the external controller. The push rod 13, the pressing mechanism 14, and the gas pump 44 cause the first electric push rod 13, which is fixed by the mounting bracket 12, to extend downwards. The first electric push rod 13 drives the pressing mechanism 14 to move downwards, so that the pressing plate 15 and the upper side of the green high-performance concrete sample are in contact. The pressing mechanism 14 applies pressure to the green high-performance concrete sample, which allows for mechanical testing. During the testing process, the green high-performance concrete sample may break. The protective frame 31 and the rotating door 32 can prevent the broken concrete pieces from splashing out. The gas pump 44 draws air to create a negative pressure in the dust collection box 41, allowing the broken concrete particles and dust to pass through the opening of the protective frame 31 and the dust collection box 41 to enter the dust collection. Inside box 41, air passes through filter 43 and is sucked away by gas pump 44. Small particles of broken concrete and dust cannot pass through filter 43, so they accumulate in dust collection box 41. After the experiment, the staff uses an external controller to reset the first electric push rod 13, close the pressing mechanism 14, and activate the second electric push rod 22 and the third electric push rod 33. The second electric push rod 22 extends forward, and the third electric push rod 33 extends backward. The second electric push rod 22 can drive the transmission block 23 to move forward, thereby moving the detection platform 24 forward and exposing the support frame 21 that was covered by the detection platform 24. At the same time, the third electric push rod 33 can drive the pusher plate 34 to move backward. The material plate 34 can drive the soft brush 35 to move backward. The material plate 34 can push the concrete fragments on the test table 24 backward. The concrete fragments can pass through the support frame 21 and the worktable 11, and finally fall into the receiving box 52 which is limited by the limiting frame 51. The soft brush 35 can sweep the test table 24 to remove the concrete fragments adhering to the test table 24. During this process, the air pump 44 runs continuously, which can suck the small particles and dust generated during the material falling into the dust collection box 41. After a period of time, the staff can remove the sealing plate 42 and take off the receiving box 52 to clean the small particles and dust in the dust collection box 41 and centrally process the concrete fragments in the limiting frame 51.This device prevents broken concrete blocks from scattering through the protective frame 31 and rotating door 32. A gas pump 44 collects small particles and dust into the dust collection box 41. A movable testing platform 24, in conjunction with a pusher plate 34 and a soft brush 35, pushes the broken concrete blocks into the collection box 52. This device collects small particles and dust generated during the testing process and collects the concrete fragments after testing, while also collecting the small particles and dust generated during the collection process. This eliminates the need for frequent cleaning of scattered dust, saving time and labor.
