Traditional concrete performance testing methods often have problems such as low precision, complex operation, and limited testing range. In order to meet the needs of modern engineering for concrete performance testing, a universal testing machine for ultra-high concrete performance testing has emerged.

[0003] The applicant found through retrieval that the Chinese patent discloses "a compression testing machine for concrete", and its publication (announcement) number is "CN 214703034 U". This patent mainly through the setting of the surrounding frame, can block the concrete debris splashing during the testing process, reduce the situation of concrete debris splashing to the ground, ensure the cleanliness of the workshop, and at the same time reduce the situation of concrete debris accidentally injuring the staff. The setting of the cleaning brush and the cleaning brush can clean the testing chassis and the machine table, ensure the cleanliness of the testing chassis and the top surface of the machine table. Keeping the testing chassis clean can ensure the stability of the concrete test block when placed, and ensure the accuracy of the test. However, it is not convenient to replace the extrusion head according to different concrete conditions, so it is not convenient to test different sizes. For this reason, we propose a universal testing machine for ultra-high concrete performance testing. Content of the Utility Model

[0032] Example 1. Please refer to the attached Figure 1 - attached Figure 4 , the pressure strip 221 is used to facilitate better fitting between the pressing plate 21 and the pressing block 22, prevent deformation between the positioning rod 23 and the positioning block 24 caused by excessive pressure, and at the same time, the limiting rod 241 and the sliding groove cooperate with each other to facilitate the limitation between the positioning block 24 and the pressing plate 21.

[0033] Example 2. Please refer to the attached Figure 1 - attached Figure 4 , by providing an inclined surface on the top of the pressure measuring base frame 311, it is convenient to guide the debris generated when the testing machine presses the concrete into the collection groove.

[0034] Specifically, the power assembly 3 drives the pressing plate 21 to move upward, so that the inclined surface of the positioning block 24 contacts the inclined surface of the limiting block 27. Then, the limiting block 27 pushes the positioning block 24 away from the positioning rod 23, facilitating the positioning block 24 to remove the clamping block from the clamping groove and disassembling the connection relationship between the pressing block 22 and the pressing plate 21, enabling personnel to replace different pressing blocks 22.

[0036] Working principle:

[0037] First, the power component 3 provides power to the disassembly component 2, and then the personnel can replace the extrusion block 22 as needed, and use the limiting block 27 to push the connection between the positioning block 24 and the positioning rod 23, so that the card block is moved out of the card slot, and then the required positioning rod 23 is inserted into the inner wall of the limiting slot, and the power component 3 drives the extrusion plate 21 to move downward, so that the limiting spring 25 drives the positioning block 24 and the card block to reset, and replaces its extrusion block 22, and uses the arc-shaped electric slide rail 41 to drive the cleaning rod 42 to move, and then the cleaning rod 42 cleans the debris inside the collection tank, and at the same time uses the pressure sensor, the stamping cylinder 32 and the control box 33 to collect concrete performance data. At this point, the entire workflow ends.
