A pressure sensor 29 is fixedly mounted on the bottom surface of the mounting block 28, and a pressure plate 30 is fixedly connected to the bottom surface of the pressure sensor 29.

[0036] In this embodiment, the hydraulic rod 27 is used to drive the mounting block 28, pressure sensor 29 and pressure plate 30 to move up and down, so that the pressure plate 30 can squeeze the concrete block. In addition, the pressure sensor 29 is used to detect the squeezing force of the pressure plate 30 on the concrete block.

[0037] For details, please refer to Figure 1 A control panel 31 is fixedly installed on the side of the testing station 1.

[0038] In this embodiment, the device is controlled via control panel 31.

[0039] For details, please refer to Figure 5 The side of the lifting block 8 fits against the inner wall of the lifting frame 6.

[0040] In this embodiment, the inner wall of the lifting frame 6 is used to limit the lifting block 8, so that the lifting block 8 can only move up and down along the axis of the screw 7. In addition, when the lifting block 8 moves to the bottom, the bottom surface of the L-shaped trailer 11 contacts the ground, ensuring that the side of the L-shaped trailer 11 can scoop up the concrete block.

[0041] Working principle: In use, first place the concrete block on the ground in front of the testing platform 1. Alternatively, a trolley can be used to move the concrete block to the front of the testing platform 1. Then, start the dual-shaft motor 14 to drive one lead screw 7 and one synchronous pulley 15 to rotate. Through the transmission between the two synchronous pulleys 15 and the synchronous belt 16, the other lead screw 7 rotates synchronously. Through the threaded engagement between the two lead screws 7 and the two lifting blocks 8, the lifting blocks 8, the mounting base 9, and the L-shaped bracket 11 move down, so that the bottom surface of the L-shaped bracket 11 is aligned with the bottom surface of the concrete block. The two sets of first electric push rods 10 on the two mounting seats 9 are then activated. These first electric push rods 10 drive the two L-shaped brackets 11 to move. The inclined surfaces 12 on the sides of the L-shaped brackets 11 allow one side of the L-shaped bracket 11 to insert into the bottom of the concrete block, thus lifting the concrete block. The dual-shaft motor 14 is then activated, driving the two lead screws 7 to reverse. Through the threaded connection between the lead screws 7 and the lifting block 8, the lifting block 8, mounting seats 9, L-shaped brackets 11, and concrete block move upwards, causing the concrete block to... The bottom surface of the concrete block is flush with the bottom surface of the inner cavity of the testing groove 3. At this time, the third electric push rod 20 is activated to drive the push block 21 towards the testing groove 3. The push block 21 pushes the concrete block on the L-shaped bracket 11 into the testing groove 3. Then, the hydraulic rod 27 is activated to drive the mounting block 28, pressure sensor 29 and pressure plate 30 to move down. The pressure plate 30 squeezes the concrete block, and the strength of the concrete is tested by the pressure detected by the pressure sensor 29. Finally, if the concrete block does not break after the test, the second electric push rod 20 is activated to push the concrete block into the testing groove 3. The push rod 17 drives the push plate 18 to move, pushing the concrete block in the detection groove 3 onto the two L-shaped brackets 11 to lower the concrete block to the ground. When the concrete block breaks, the two L-shaped brackets 11 continue to move upward, pulling the receiving box 23 out of the inner cavity of the collection groove 22. Then, the second electric push rod 17 drives the push plate 18 to move, pushing the concrete block in the inner cavity of the detection groove 3 into the inner cavity of the receiving box 23. The broken concrete block is then collected by the receiving box 23.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
