Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to a concrete detection device for construction engineering. Background Art

[0002] Concrete, referred to as "concrete", is a general term for engineering composite materials that are cemented into a whole by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion, which is mixed and obtained by mixing. It is also called ordinary concrete, which is widely used in civil engineering.

[0003] At present, some existing concrete testing devices usually use an extrusion method to test the strength of concrete when testing concrete. However, the concrete block will break after extrusion to produce concrete fragments. After the test is completed, the concrete fragments will remain on the surface of the test bench. In order to ensure the accuracy of the test, personnel are required to manually clean the test bench before continuing the test. This is quite inconvenient to use and relatively time-consuming and labor-intensive to clean. For this reason, we propose a concrete testing device for construction projects to solve or improve the above problems. Utility Model Content

The first hydraulic telescopic rod 4 can drive the test bench 5 rotatably installed at one end of the output shaft to move, and the test bench 5 drives the rotatably installed first sliding block 11 to move inside the first slide groove 3. An auxiliary support plate is fixed to the inner surface of the device housing 1. When the test bench 5 is located inside the device housing 1 and the bottom of the test bench 5 contacts the top of the auxiliary support plate, the auxiliary support plate can provide certain support for the test bench 5. A collection box 2 is inserted into the inside of the device housing 1. The collection box 2 is located on one side of the bottom of the test bench 5 near the edge. The top of the side of the test bench 5 away from the first hydraulic telescopic rod 4 is located on the top side of the collection box 2. When concrete fragments slide from the surface of the test bench 5, they will fall into the inside of the collection box 2. The cleaning component is arranged on the surface of the test bench 5.

[0020] The cleaning component includes a second slide 10 opened inside the test bench 5. The second slide 10 is symmetrically opened in two groups inside the test bench 5. A drive motor 13 is fixed inside the test bench 5. A threaded rod 12 is fixed to the top of the output shaft of the drive motor 13. The drive motor 13 can drive the threaded rod 12 fixed to the top of the output shaft to rotate. A second slider 14 is sleeved on the surface of the threaded rod 12 and threadedly connected to the threaded rod 12. At the same time, the second slider 14 is located inside the second slide 10 and is slidably connected to the second slide 10. When the threaded rod 12 rotates, The threaded second slider 14 is driven to move, so that the second slider 14 slides inside the second slide groove 10, and the fixed frame 6 fixed to the top of the second slider 14 will drive the fixed frame 6 to move when the second slider 14 moves. The scraper 7 inserted inside the fixed frame 6 will drive the scraper 7 inserted inside to move when the fixed frame 6 moves. A part of the scraper 7 is located on the bottom side of the fixed frame 6 and contacts the top of the test bench 5. When the fixed frame 6 drives the scraper 7 to move, the part of the scraper 7 that contacts the top of the test bench 5 will scrape the top of the test bench 5.

[0021] Working principle: when it is necessary to test the concrete, first place the concrete block on the top of the test bench 5 at a position on one side of the bottom of the second hydraulic telescopic rod 9. At this time, the second hydraulic telescopic rod 9 drives the pressure plate to move so that the pressure plate can squeeze the concrete block, thereby testing the strength of the concrete block. When the test is completed and the top of the test bench 5 needs to be cleaned, the second hydraulic telescopic rod 9 drives the pressure plate to move in the opposite direction so that the pressure plate is removed from the surface of the concrete block. At this time, the first hydraulic telescopic rod 4 will drive one end of the test bench 5 to move, so that the top of the test bench 5 is tilted at a certain angle. At the same time, when one end of the test bench 5 moves, the test bench 5 will drive the rotatably connected first slider 11 to move, so that when the test bench 5 rotates around the rotating axis on the surface of the first slider 11, a certain displacement is also generated through the first slider 11, so that the other end of the test bench 5 moves close to the collection box. 2 is positioned on one side of the top center of the test bench 5, so that relatively large concrete fragments can slide down from the top of the test bench 5 by gravity and fall into the interior of the collection box 2 for unified collection, which is convenient for unified cleaning. At the same time, the driving motor 13 will drive the threaded rod 12 to rotate, so that the threaded rod 12 drives the second slider 14 to move. When the second slider 14 moves, it drives the fixed frame 6 to move. When the fixed frame 6 moves, it drives the scraper 7 to move to scrape and clean the surface of the test bench 5, so that the concrete fragments are scraped off the top of the test bench 5, and the top of the test bench 5 is cleaned. There is no need for personnel to manually clean the top of the test bench 5. It is relatively convenient to use, and cleaning is relatively time-saving and labor-saving. At the same time, because the scraper 7 is inserted into the interior of the fixed frame 6, when the scraper 7 is worn and the cleaning effect is reduced, the scraper 7 can also be pulled out from the interior of the fixed frame 6 and replaced, thereby ensuring the cleaning effect of the device.
