Description

Technical Field

[0001] The utility model relates to the technical field of steel structure production, and more specifically, to a hardness detection device with high stability for steel structure production. Background Art

[0002] Steel structure is composed of steel plates and is one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel frames and other components made of steel sections and steel plates. Hardness is the ability to resist harder objects pressing into its surface, so steel structures need to be tested using hardness testing devices. During the test, the steel plates need to be clamped and fixed, but the clamping mechanisms of most devices on the market are too simple to manufacture, and they cannot be stably clamped according to steel of different thicknesses and sizes during use. Accidental sliding is prone to occur during testing, which can easily lead to instability of the steel body and poor stability, affecting the final test results, reducing work efficiency and work quality, and most devices cannot adjust the position of the hardness tester in time according to the test requirements, and cannot enable the hardness tester to perform hardness tests on different areas of the steel plate during use, which affects production and processing and reduces the practicality of the device. For this reason, we have launched the following device. Utility Model Content
