[0037] Working process of the present invention:

[0038] During operation, a group (three) of concrete test blocks are placed in the three storage slots 3 respectively according to the requirements, and then the X-direction linear driving mechanism 502 in the three-dimensional motion platform mechanism drives the X-direction slide 501 to move, so that the three groups of test block clamping mechanisms correspond to the concrete test blocks in the three storage slots 3 in the Y direction respectively, and then the Y-direction linear driving mechanism 505 drives the Y-direction slide 504 to move in the direction of the concrete test blocks in the storage slots 3, so that the three groups of test block clamping mechanisms all move in the direction of the corresponding concrete test blocks, and then the piston end of the driving cylinder 700 in the test block clamping mechanism contracts, and the connecting block 70 3, the two sets of rollers 705 move with it, and the two sets of rollers 705 cooperate with the long key grooves 704 on the two sets of bending parts 701 respectively to make the two sets of bending parts 701 swing, so that the two sets of clamping plates 702 in the separated state move toward the middle to clamp the concrete test block in the storage groove 3, and then the Z-direction driving cylinder 506 in the three-dimensional motion platform mechanism drives the lifting plate 507 to rise, so that the two sets of clamping plates 702 clamping the concrete test block are separated from the storage groove 3. After the concrete test blocks in the three storage grooves 3 are taken away, another set of concrete test blocks can be added to maintain the continuity of the detection work, and then the Y-direction straight The linear drive mechanism 505 drives the Y-direction slide plate 504 in the reverse direction away from the storage slot 3, and then the X-direction linear drive mechanism 502 drives the X-direction slide plate 501 to move in the direction of the test block pressurization detection mechanism, so that the three groups of test block clamping mechanisms correspond to the three groups of test block pressurization detection mechanisms in the Y direction, and then the Y-direction linear drive mechanism 505 drives the Y-direction slide plate 504 to move toward the opening of the rectangular frame seat 400 of the test block pressurization detection mechanism, so that the concrete test blocks clamped by the two groups of clamping plates 702 in the three groups of test block clamping mechanisms are respectively sent to the upper part of the pressure platform 403 inside the rectangular frame seat 400 in the three groups of test block pressurization detection mechanisms. Then the Z-direction driving cylinder 506 drives the lifting plate 507 to descend, and the concrete test block is located at the center of the pressure platform 403. Then the piston end of the driving cylinder 700 in the test block clamping mechanism extends out, and through the linkage of the mechanism, the two groups of clamping plates 702 are separated to release the clamping of the concrete test block. Then the Y-direction linear driving mechanism 505 drives the Y-direction slide plate 504 in the reverse direction, so that the two groups of clamping plates 702 in the test block clamping mechanism withdraw from the rectangular frame seat 400 in the test block pressurization detection mechanism. Then the X-direction linear driving mechanism 502 drives the X-direction slide plate 501, and the three groups of test block clamping mechanisms retreat to the working origin.

[0039] After a concrete test block is placed at the center of the pressure platform 403, the piston end of the opening and closing driving cylinder 407 contracts, the protective door 406 descends, and the opening of the rectangular frame seat 400 is closed. Then the hydraulic cylinder 401 drives the lower pressure plate 402 to move downward to apply pressure to the concrete test block at the center of the pressure platform 403. The pressure on the concrete test block is sensed by the pressure sensor, and the pressure sensor sends the sensed pressure value in the form of a signal to the external host. After analysis and judgment, the external host uses the average strength value as the strength of this group of concrete test blocks. After the test block pressurization test is completed, the piston end of the opening and closing driving cylinder 407 extends, the protective door 406 is in an open state, and the push cylinder 411 drives the push plate 412 to move, pushing away the waste on the upper end surface of the pressure platform 403, so that the waste falls into the receiving trough 405 through the material guide trough 404, and then the push cylinder 411 drives the push plate 412 to retreat. The description of the above working process is only the compressive strength test process of a group of concrete test blocks.

There are two groups of opening and closing driving cylinders (407) which are axially and vertically arranged on the two side plates of the rectangular frame seat (400). The piston ends of the two groups of opening and closing driving cylinders (407) are respectively connected to the two upper top corners of the protective door (406) through connecting pieces (410).

4. The concrete test block compressive strength testing device according to claim 1, characterized in that The test block pressurization detection mechanism further comprises a push cylinder (411) and a push plate (412). The push cylinder (411) is arranged on the side of the opening of the rectangular frame seat (400) which is away from the test block clamping mechanism. The piston rod of (411) is connected to the push plate (412) located at the opening of the rectangular frame seat (400), and the lower end surface of the push plate (412) is flush with the upper end surface of the pressure platform (403).
