There are many indicators for concrete testing. Therefore, when testing a kind of concrete, a batch of prefabricated concrete parts are usually made first, and then various indicators are tested for the prefabricated concrete parts. The strength of concrete is an important indicator to measure the quality of concrete. The strength of concrete is obtained by testing the concrete test block through the concrete testing device. The strength of the concrete test block needs to be cured in the curing room for a specified time before proceeding. When the concrete test block is cured for the specified time, the concrete test block is transported to the area to be tested for testing. Manual testing is required during the test. Align, load the test block until it is broken, and move the broken test block to the waste area after breaking.

However, the existing concrete strength detector can only test the strength from a single angle. In some special occasions, the concrete may be subjected to lateral pressure. Therefore, it is very important to design a detection device that can measure the strength of concrete from different directions. Needed.
