Description

Technical Field

[0001] The utility model belongs to the technical field of concrete, and in particular relates to a concrete hardness detection device. Background Art

[0002] Concrete refers to an artificial stone made by mixing cement as the main binder, with water, sand, gravel, and if necessary, chemical admixtures and mineral admixtures in appropriate proportions, and then evenly mixing, compacting, forming, and curing and hardening. Before concrete is used on a large scale, it is usually made into concrete test blocks, and the hardness of the concrete test blocks is tested using testing equipment.

[0003] According to a concrete hardness testing device with authorization announcement number CN216449368U, the patent is a known prior art, and although the patent has the advantage of being able to press the concrete test block to be tested to prevent the concrete test block from moving during testing, the technical solution of the patent still has the following defects in actual use: after the hardness test of a concrete test block is completed, the tester needs to first remove the broken concrete test block from the placement plate, then clean the broken blocks on the placement plate, and finally place a new concrete test block to be tested on the placement plate. Such an operation process will waste time, slow down the hardness test speed of the concrete test block, and thus reduce the working efficiency of the testing device. For this reason, we propose a concrete hardness testing device. Utility Model Content

At this time, the pressure value applied by the extrusion block (i.e., the compressive strength value of the concrete test block) will be displayed on the display screen of the concrete test block pressure testing machine 2, thereby facilitating the detection of the hardness of the concrete.

[0024] In this embodiment, after the concrete test block to be tested is placed into the concrete test block placement box 5, the adjusting bolt 61 is rotated to rotate and move, and the adjusting bolt 61 will drive the fixing block 62 to move, and the fixing block 62 will drive the fixing pad 63 to move, so that the fixing pad 63 is in close contact with one side of the concrete test block, thereby facilitating the adjustment and fixation of the concrete test block, thereby improving the stability of the concrete test block during testing. At the same time, the setting of the discharge port 7 makes it easy to clean out the broken small concrete fragments from the inside of the concrete test block placement box 5 after the concrete test block testing is completed.

[0026] In this embodiment, when the concrete test block in one concrete test block placement box 5 is inspected, the rotating motor 33 is turned on to rotate the rotating shaft 32, and the rotating shaft 32 drives the turntable 4 to rotate ninety degrees. At this time, another concrete test block placement box 5 containing the concrete test block to be inspected will move to the bottom of the extrusion block of the concrete test block pressure testing machine 2. In this way, the concrete test block in the next concrete test block placement box 5 can be inspected while the debris in the previous concrete test block placement box 5 is cleaned, which greatly saves the time of concrete test block inspection and speeds up the speed of concrete test block inspection, thereby improving the working efficiency of the inspection device;

[0027] In the above scheme, it should be noted that: the concrete block pressure testing machine 2 in the present application is a product of the prior art, and the internal structure and working principle of the concrete block pressure testing machine 2 are both existing public technologies.

[0028] The working principle and use process of the utility model are as follows: first, the concrete test block to be tested is placed in the concrete test block placement box 5, and then the adjusting bolt 61 is rotated to make it rotate and move, and the adjusting bolt 61 drives the fixing block 62 to move, and the fixing block 62 drives the fixing pad 63 to move, so that the fixing pad 63 is in close contact with one side of the concrete test block, so as to facilitate the adjustment and fixation of the concrete test block;

In this way, the concrete test block inside the next concrete test block placement box 5 can be inspected while the debris inside the previous concrete test block placement box 5 is cleaned, which greatly saves the time for concrete test block inspection, speeds up the speed of concrete test block inspection, and thus improves the working efficiency of the inspection device.
