The cleaning scraper 803 is adapted to the detection platform 4 and the clamping plate 602. A collecting basket 5 is provided at the lower front side of the detection platform 4 for collecting the cleared materials.

[0019] In this embodiment, the above-mentioned device also includes a detection box 1, and the detection table 4, the clamping mechanism 6, the heavy pressure detection mechanism 7 and the cleaning mechanism 8 are all installed in the detection box 1. A transparent box door is provided in front of the detection box 1 for observing the detection situation. The collection basket 5 is arranged at the bottom of the detection box 1. The use of the detection box can protect the above-mentioned device to prevent debris from splashing onto the staff when testing the concrete test block.

[0020] The cleaning scraper 803 is arranged around the moving plate 803, the moving plate 803 is connected to the output end of the cleaning cylinder 801, a support plate 804 fixed to the moving plate 803 is arranged above the moving plate 803, the cleaning brush 805 is installed on the support plate 804, and the cleaning cylinder 801 is vertically installed on the rear side wall of the detection box 1. The cleaning brush and the cleaning scraper are integrated together and driven by a cleaning cylinder, which has a simple and compact structure.

[0021] The clamping mechanism 6 is further provided with a clamping cylinder 601, which is installed on the side of the detection box 1, and the clamping plate 602 is driven by the clamping cylinder 601. The structure is symmetrical and the working performance is stable.

[0022] The heavy pressure detection mechanism also includes a magnet block 703 located above the detection weight 704 and an electromagnet 702 located above the magnet block 703, the electromagnet 702 is connected to the output end of the lifting cylinder 701, and the lifting cylinder 701 is installed on the top of the detection box 1; the two sides of the magnet block 703 are each connected to a sliding sleeve 706 through a connecting rod 707, and the sliding sleeve 706 is installed on a guide column 705, and the guide column 705 is vertically fixed in the detection box 1, and the detection weight 704 is magnetically fixed under the magnet block 703.

[0024] Application of this utility model:

[0025] First, open the box door 2, place the concrete test block to be tested on the test bench 4, and after the placement is completed, close the box door 2, and then use the touch terminal 3 to control the pair of clamping cylinders 601 in the clamping mechanism 6 to work, so that it pushes a pair of clamping plates 602 to move toward each other along the test bench 4 until it contacts the concrete test block, so as to clamp and fix the concrete test block and keep it stable during the subsequent testing process. After the concrete test block is fixed, disconnect the power supply of the electromagnet 702, the electromagnet 702 loses its attraction, and the test sinker 704 and the magnet block 703 fall on the concrete test block under the action of gravity, under the guidance of the sliding sleeve 706 and the guide column 705, to perform hardness testing. After the test is completed, the lifting cylinder 701 drives the electromagnet 702 to move downward until it contacts the magnet block 703, and then it is powered on to generate magnetism, attracting the magnet block 703 and the detection pendant 704 to rise to the set height, and then falls again to achieve the heavy pressure of the concrete test block, and the hardness test of the concrete test block is performed again. This is repeated to achieve multiple hardness tests of concrete test blocks with different curing dates under the same conditions at different heights. At the same time, these height data will also be displayed in real time on the touch terminal 3 for the staff to watch, thereby ensuring the adequacy and comprehensiveness of the concrete hardness test and enhancing the test effect. After the test is completed, the staff opens the box door 2 to take away the tested concrete test block. After that, the lifting cylinder 701 is controlled to drive the electromagnet 702, the magnet block 703 and the detection sinker 704 to rise to a height matching the cleaning brush 805, and then the cleaning cylinder 801 in the cleaning mechanism 8 is controlled to work, pushing the moving plate 802 to move forward, so that it drives the cleaning scraper 803 and the cleaning brush 805 to move forward, so that the cleaning scraper 803 scrapes and pushes the debris remaining on the working surface of the pair of clamps 602 and the upper end of the detection table 4, and at the same time, the cleaning brush 805 also brushes the debris attached to the lower end of the detection sinker 704, and the debris falls into the collection basket 5 as the cleaning scraper 803 pushes and cleans. When the concrete test block fails the hardness test and is broken, it can also be cleaned by the cleaning cylinder 801 and the cleaning scraper 803 to make the unqualified products fall into the collection basket 5 for collection. The cleaning mechanism is used to clean the pair of clamping plates 602, the test table 4 and the test weight 704 simultaneously, which saves time and effort, is easy and convenient, and can effectively improve the convenience of cleaning. After the collection basket 5 is full, the collection basket 5 is pulled out to separate the collection basket 5 from the test box 1, so that the staff can clean the waste and debris dropped inside it.
