[0031] A protective shell 22 is provided on three sides of the testing machine 1, and the rear side thereof is unobstructed. A camera assembly is provided at the unobstructed location to monitor the detection status of the concrete block.

[0032] A first groove 8 is provided on the top of the carrying plate 7, and a first telescopic rod 9 is symmetrically fixedly installed on the left and right sides of the first groove 8, and a first push plate 10 is fixedly installed on the end of the first telescopic rod 9, and the spacing between the two ends of the first push plate 10 and the front and rear sides of the groove can be ignored. A slide rail 11 is embedded and fixedly installed in the front and rear of the first groove 8, and a second telescopic rod 12 is slidably connected in the slide rail 11. A second push plate 13 is fixedly installed on the end of the second telescopic rod 12, and side grooves 14 are provided on both sides of the second push plate 13. Short rails 15 are fixedly installed on the inner wall of the side groove 14, and an extension plate 16 is slidably connected to the short rail 15. Among them, the fully automatic pressure testing machine is matched with an intelligent system, and the operation of the first telescopic rod 9 is controlled by the intelligent system. The operation of the first telescopic rod 9 drives the operation of the first push plate 10. The intelligent system controls the second telescopic rod 12 to move along the slide rail 11, and then drives the second push plate 13 to move. The intelligent system controls the operation of the second telescopic rod 12, and the operation of the second telescopic rod 12 drives the second push plate 13 to move. The intelligent system controls the extension plate 16 to move along the short rail 15 to control the length of the second push plate 13;

[0033] By controlling the movement of the first push plate 10 and the second push plate 13, the position of the concrete block placed in the first groove 8 is controlled;

[0034] A second hydraulic press 17 is arranged on the top of the top plate 5, the output end of the second hydraulic press 17 faces downward and penetrates the top plate 5, a combination plate 18 is fixedly installed on the output end of the second hydraulic press 17, a second groove 19 is arranged at the bottom of the combination plate 18, a plurality of lifting rods 20 are arranged in the second groove 19, a pressing plate 21 is arranged at the bottom of each lifting rod 20, and the area of ​​each pressing plate 21 is inconsistent, the purpose of which is to apply pressure to the concrete block by setting the pressing plates 21 with different area values, the intelligent system controls the lifting rod 20 to drive the pressing plate 21 to run until the pressing plate 21 contacts the concrete block, and then the second hydraulic press 17 runs to drive the pressing plate 21 to apply pressure to the concrete block for detection;

[0035] An electrically controlled bearing ball 23 is provided at the connection between the pressing plate 21 and the lifting rod 20, and the rotation angle of the pressing plate 21 is controlled by the electrically controlled bearing ball 23;

[0036] The intelligent system sets a preset concrete block placement area vertically below the pressing plate 21 according to the position of the pressing plate 21, and each concrete block placement area matches the pressing plate 21, so that the pressing plate 21 can be aligned with the concrete block when it descends;

[0037] The detection process of the top flat surface of the concrete block is as follows: the intelligent system first confirms the first concrete block placement area that the concrete block is expected to enter, and first drives the two first push plates 10 to run simultaneously through the intelligent system to clamp the concrete block, and then pushes the concrete block to move to the same row as the first concrete block placement area. Then the intelligent system drives the two second push plates 13 to adjust their own plate lengths first, so that the plate length of the second push plates 13 is slightly shorter than the clamping surface length of the concrete block, so as to facilitate passing through the spacing between the two first push plates 10, and then drives the two second push plates 13 to clamp the concrete block. At this time, the two first push plates 10 are reset a little distance, so that the two second push plates 13 can push the concrete block to the first concrete block placement area, and finally the two first push plates 10 clamp it again. Concrete block, at this time, the concrete block is clamped by the two first push plates 10 and the two second push plates 13, and the position of the concrete block is adjusted again to ensure that the position of the concrete block is accurate. After confirming that the concrete block enters the first concrete block placement area, the first push plate 10 and the two second push plates 13 are reset, and then the pressing plate 21 above them is driven to descend to start pressure detection. The camera component monitors the status of the concrete block in real time. If the concrete block is broken before reaching the preset pressure, it is judged that the concrete block is unqualified. If the concrete block is not broken after reaching the preset pressure, the pressing plate 21 is reset, and the concrete block is moved to the second concrete block placement area by the first push plate 10 and the second push plate 13 according to the above-mentioned detection process, and detection is performed again until the pressure value of the concrete block is detected;

[0038] The above detection process is carried out in the order of the area of ​​the pressing plate 21 from small to large. According to the pressure formula F=pS, the larger the area of ​​the pressing plate 21, the larger the contact area between the pressing plate 21 and the concrete block, and finally the greater the pressure value of the pressing plate 21 on the concrete block, until the area of ​​the pressing plate 21 is equal to or slightly larger than the top area of ​​the concrete block, and the detection is completed. This pressure detection using pressing plates 21 of different areas is also to obtain the pressure data of the small area (relative to the top surface of the concrete block) of the pressure structure on the concrete block. The camera component is used to obtain the condition when the top surface of the concrete block is pressed by the small area (relative to the top surface of the concrete block) when the concrete block is not broken. If the concrete block is not broken, but cracks appear on its top surface, the specifications of the pressing plate 21 and the pressure data of the pressing plate 21 when the cracks appear are recorded;

[0039] The detection process of the top edge structure of the concrete block is as follows: the intelligent system drives the first push plate 10 and the second push plate 13 to operate, and the concrete block is moved to the preset area between the two pressing plates 21 by the first push plate 10 and the second push plate 13, and then the pressing plates 21 on both sides above the concrete block are driven to rotate 45 degrees, and then the lifting rod 20 is driven to descend until the pressing plate 21 is against the edge structure on the top of the concrete block. At this time, the lower area of ​​the concrete block is clamped and fixed by the first push plate 10 and the second push plate 13, and the edge structures on both sides of the top are pressure-detected by the pressing plates 21, and then the pressure value of the broken edge structure of the top of the concrete block is obtained by the camera assembly, and then the pressure detection of the edge structure of the concrete block is completed, and the two symmetrical edge structures on the top of the concrete block are detected each time until all the four edge structures on the top of the concrete block are detected.

[0040] The detection process of the top diagonal structure of the concrete block is as follows: the intelligent system drives the first push plate 10 and the second push plate 13 to operate, and moves the concrete block to the preset area. Then, the intelligent system drives the two pressing plates 21 at the diagonal positions of the concrete block to rotate 45 degrees, and then drives the lifting rod 20 to descend until the pressing plate 21 is against the diagonal structure at the top of the concrete block. At this time, the lower area of ​​the concrete block is clamped and fixed by the first push plate 10 and the second push plate 13, and the diagonal structures on both sides of the top are pressure-detected by the pressing plate 21. Then, the pressure value of the broken diagonal structure at the top of the concrete block is obtained by the camera assembly, and then the pressure detection of the diagonal structure of the concrete block is completed. Each time, the two diagonal structures at the diagonal opposite sides of the top of the concrete block are detected until all the four diagonal structures at the top of the concrete block are detected.

[0041] When the top surface of the concrete block is subjected to pressure testing, the lower area thereof does not need the first push plate 10 and the second push plate 13. The reason is that the pressure plate 21 is pressed down at an angle horizontal to the top surface of the concrete block for testing, and the concrete block will not be displaced. Moreover, when the concrete block is subjected to pressure testing, the volume of the concrete block will change. The first push plate 10 and the second push plate 13 clamping the concrete block will cause abnormal deformation of the concrete block, which will affect the pressure testing result. When the top edge structure and the top diagonal structure of the concrete block are tested, the first push plate 10 and the second push plate 13 are required to clamp the concrete block to prevent the concrete block from moving, and pressure testing is performed on the edge structure and the diagonal structure of the concrete block. The ultimate goal is to obtain the pressure value when the edge structure and the diagonal structure at the top of the concrete block are broken. Therefore, the final value effect caused by the first push plate 10 and the second push plate 13 clamping the concrete block can be ignored.

[0042] Hollow grooves 24 are arranged in the lower part of the four side walls of the first groove 8. After each detection of a concrete block, the intelligent system drives the main motor 6 to operate, driving the bearing plate 7 to rotate, and the debris on the surface of the bearing plate 7 will be thrown out through the hollow grooves 24, which simplifies the cleaning work after the concrete block is broken, reduces manual intervention, and improves the test efficiency;

[0043] Four metal tubes 27 are arranged in the detection chamber 26. The metal tubes 27 are retractable structures and penetrate the top surface of the detection chamber 26. Four connecting holes 28 are arranged on the first groove 8. Each connecting hole 28 is vertically matched with a metal tube 27 to accommodate the metal tube 27. A remotely adjustable valve is arranged at the connecting hole 28 to control the opening and closing of the connecting hole 28. The concrete block is moved to a preset position by the first push plate 10 and the second push plate 13. Then the intelligent system drives the metal tube 27 to extend and the connecting hole 28 to open, so that the metal tube 27 is against the bottom of the concrete block, and then drives the matching pressing plate 21 to press against the top flat surface of the concrete block, and then drives the first hydraulic press 25 and the second hydraulic press 17 to run simultaneously, so that the metal tube 27 is inserted into the concrete block until the metal tube 27 penetrates the concrete block. The internal structure of the concrete block is obtained by the press fit of the first hydraulic press 25 and the second hydraulic press 17.

[0044] A driving motor 29 is fixedly installed at the bottom of the detection chamber 26, and a rotating rod 30 is fixedly installed on the output end of the driving motor 29. A cutting knife 31 is installed on the end bearing of the rotating rod 30. After the metal tube 27 is obtained, it starts to reset and shrink until the metal tube 27 shrinks and enters the detection chamber 26. At this time, the obtained internal structure of the concrete block enters the detection chamber 26, and part of its upper area is exposed outside the metal tube 27. The intelligent system drives the cutting knife 31 to rotate to a horizontal position, and then starts the driving motor 29. The driving motor 29 drives the rotating rod 30 to rotate, and the rotation of the rotating rod 30 drives the cutting knife 31 to rotate. The internal structure of the obtained concrete block is cut and detected by the rotation of the cutting knife 31, and the intelligent system obtains the value at which the cutting knife 31 cuts the internal structure of the concrete block.

[0045] The equipment can detect the overall structure, edge structure, diagonal structure and internal structure of concrete blocks, and can automatically clean each concrete block after detection, greatly improving the detection quality, accuracy and efficiency of concrete blocks.
