DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-5 , the present invention provides a technical solution: a device for detecting the crack resistance of concrete, including a table plate 1. A through groove 2 is opened in the middle of the table plate 1. First clamping grooves 3 and second clamping grooves 4 are respectively opened on both sides in the through groove 2. Anti-blocking grooves 5 are opened at the bottom of the first clamping groove 3 and the second clamping groove 4 near the through groove 2. Loading plates 6 are installed inside both the first clamping groove 3 and the second clamping groove 4. A pull rod 7 is fixed at the end of the loading plate 6 inside the second clamping groove 4. The end of the pull rod 7 penetrates through the side wall of the table plate 1 and is fixed with a handle 9. A first spring 8 is nested outside the pull rod 7. Both ends of the first spring 8 are connected to the end of the loading plate 6 and the inner wall of the second clamping groove 4 respectively. The end of the loading plate 6 is in snap connection with the first clamping groove 3. A waste collection box 18 is arranged below the through groove 2. The other end of the loading plate 6 is in sliding connection with the second clamping groove 4. The pull rod 7 and the table plate 1 form a sliding connection. By pulling the handle 9, the loading plate 6 can be separated from the second clamping groove 4, so that the broken stones on the top of the loading plate 6 can quickly fall into the waste collection box 18, which is convenient for taking out the broken stones;

[0023] An L-shaped frame 10 is fixed on the top of the table plate 1. A cylinder 16 is fixedly penetrated through the top of the L-shaped frame 10. A pressure sensor 11 is fixed at the lower end of the cylinder 16. A pressing block 12 is fixed at the lower end of the pressure sensor 11. A protection mechanism is arranged outside the cylinder 16. The protection mechanism includes a movable cover 13. The end of the cylinder 16 penetrates through the middle of the movable cover 13. Both the pressure sensor 11 and the pressing block 12 are located inside the movable cover 13. A fixing ring 14 is fixed on the outer wall of the end of the cylinder 16. The movable cover 13 is in sliding connection with the end of the cylinder 16. A second spring 15 is nested outside the cylinder 16. Both ends of the second spring 15 are connected to the bottom of the fixing ring 14 and the top of the movable cover 13 respectively. During the process of breaking the concrete stone, the movable cover 13 can cover the top of the through groove 2, avoiding the situation that the stones fly out and hurt the operator during the process of breaking the concrete stone.

[0024] A computer 17 is arranged on the top of the table plate 1. The computer 17 is electrically connected to the pressure sensor 11. The pressure sensor 11 can transmit the detected signal to the computer 17, and the computer 17 can analyze the obtained data to obtain the crack resistance of the concrete stone.

[0025] The design of the anti-blocking groove 5 ensures that after the first card slot 3 and the load-bearing plate 6 are separated, the broken stones will not enter the inside of the first card slot 3, enabling the load-bearing plate 6 to engage with the first card slot 3 and ensuring the normal operation of the entire structure.

[0026] Working principle: When using this concrete anti-cracking performance detection device, first place the concrete stone to be detected into the through groove 2, and then start the cylinder 16 to work. The cylinder 16 drives the pressing block 12 and the movable cover 13 to move downward simultaneously. The movable cover 13 first contacts the top of the table board 1. When the pressing block 12 continues to move downward, the movable cover 13 compresses the second spring 15, and the pressing block 12 applies pressure to the concrete stone. The pressure sensor 11 transmits the detected signal to the computer 17. When the pressure sensor 11 detects the maximum pressure value, the concrete stone breaks. At this time, the computer 17 controls the cylinder 16 to move upward and reset.

[0027] When the stone on the top of the load-bearing plate 6 needs to be removed, pull the handle 9 to the right. Then the handle 9 drives the pull rod 7 and the load-bearing plate 6 to move to the right simultaneously until the load-bearing plate 6 completely enters the inside of the second card slot 4 and the first spring 8 is compressed. At this time, the broken stones in the through groove 2 fall into the waste collection box 18. Release the handle 9, and under the elastic force of the first spring 8, the load-bearing plate 6 moves to the left and resets, and the end of the load-bearing plate 6 engages with the first card slot 3 again.

[0028] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
