[0022] In the process of detecting the compressive performance of the concrete through the test device, in order to prevent the concrete sample from moving randomly and affecting the detection, the servo motor 601 is started to drive the bidirectional threaded column 602 to rotate, and the bidirectional threaded column 602 is supported by the support seat 603 at this time. The transmission seat 604 moves towards each other under the rotation of the bidirectional threaded column 602, and the transmission seat 604 moves to drive the fixed seat 605 and the transmission plate 609 to move together because the transmission seat 604 is connected with the fixed seat 605 and the transmission plate 609. The clamping seat 607 is connected with the fixed seat 605 through the threaded rod 606, and the clamping seat 607 can be rotated to generate a pushing force on the clamping seat 607 in advance, so that the clamping seat 607 moves.

The concrete sample is covered on the side close to the worker, and then when the concrete sample breaks and flies, it is blocked by the rack 2 and the transparent protective plate 613, so as to prevent it from flying and contacting the worker and causing injury. During the movement of the clamping seat 607 for fixing the concrete sample, the rising protection of the transparent protective plate 613 can be completed, so as to play the role of convenient clamping and protection of workers when the test device for testing the compressive performance of the concrete is used.

[0024] In summary, the concrete compressive strength testing device uses the base 1 in advance to be placed in the designated position, then the concrete sample is placed on the top of the workbench 5, and then the electric push column 3 at the top of the rack 2 is started, at this time the electric push column 3 is stretched to drive the pressure seat 4 to move downward until the pressure seat 4 contacts the concrete sample on the top of the workbench 5, and then a huge pressure is generated on the concrete sample, so that the concrete sample is gradually destroyed, so that the compressive strength of the concrete is known, which is the prior art and will not be described in detail here.
