DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0022] Refer to Figures 1-3 , a concrete strength detection device, including a detection table 1 used for detecting the strength of a concrete specimen. A gantry 6 is fixedly connected to the top of the detection table 1. A strength detection mechanism is arranged on the gantry 6. A retaining frame 10 is fixedly connected to the top of the detection table 1. A clamping mechanism for fixing the concrete specimen is arranged between the retaining frame 10 and the gantry 6. A cleaning port 12 is opened on the top of the detection table 1. A cavity 14 is opened inside the detection table 1. A concrete debris cleaning mechanism is arranged among the detection table 1, the cavity 14 and the cleaning port 12. A chip collection box 2 is slidably sleeved inside the detection table 1.

[0023] Furthermore, the clamping mechanism includes two lower cylinders 9. Lower connecting rods are fixedly connected to the output shafts of the two lower cylinders 9. Clamping plates 11 are fixedly connected to the ends of the two lower connecting rods close to each other. Place the concrete specimen in the retaining frame 10 and on two baffle plates 15. Drive the two clamping plates 11 to approach each other through the output shafts of the two lower cylinders 9, so as to clamp and fix the two sides of the concrete specimen, avoiding shaking and affecting the accuracy of the test data.

[0024] Furthermore, the two clamping plates 11 are respectively slidably sleeved inside the retaining frame 10, which is beneficial to guiding the clamping plates 11 and making their movement more stable.

[0025] Furthermore, the strength detection mechanism includes an upper cylinder 7 fixedly connected to the top of the gantry 6. An upper connecting rod is fixedly connected to the output shaft of the upper cylinder 7. An extrusion head 8 is fixedly connected to the bottom end of the upper connecting rod. Drive the extrusion head 8 to move downward through the upper cylinder 7 to detect the strength of the concrete specimen.

[0026] Further, the concrete debris cleaning mechanism includes a servo motor 4 fixedly connected to one side of the detection table 1, and two double-headed screws 16 rotatably connected to the inner walls on both sides of the cavity 14. The output shaft of the servo motor 4 is fixedly connected to one end of the corresponding double-headed screw 16. The other ends of the two double-headed screws 16 are both fixedly connected with sprockets 17. The same chain 18 is drivingly connected between the two sprockets 17. Two sliding seats 19 are threadedly sleeved on the outer sides of the two double-headed screws 16. The same baffle 15 is fixedly connected between the two sliding seats 19 on the same side. The two baffles 15 are in mutual contact and are both slidably sleeved in the cleaning port 12. By driving the rotation of one double-headed screw 16 by the servo motor 4, under the transmission of the two sprockets 17 and the chain 18, the synchronous rotation of the two double-headed screws 16 is driven. The two double-headed screws 16 drive the four sliding seats 19 and the two baffles 15 to retract away from each other into the cavity 14 without blocking the cleaning port 12. At this time, the broken concrete debris falls from the cleaning port 12 into the chip collecting box 2 for collection and treatment, thereby achieving the purpose of self-cleaning. When the top of the baffle 15 enters the cavity 14, it will abut and slide against the top of the cavity 14 to achieve the purpose of cleaning the top of the baffle 15, avoiding the attachment of debris to the top of the baffle 15 and being unfavorable for the next use. After the cleaning is completed, reverse-start the servo motor 4 so that the two baffles 15 approach and abut each other. At this time, the cleaning port 12 can be completely blocked by the two baffles 15 for use in detecting the strength of the next concrete sample.

[0027] Further, two guide rods 20 are fixedly connected to the inner walls on both sides of the cavity 14. The four sliding seats 19 are respectively slidably sleeved on the outer sides of the corresponding guide rods 20, which can guide the sliding seats 19 to make their movement more stable and smooth.

[0028] Further, a plurality of support rods 13 are fixedly connected to the inner walls on the front and rear sides of the cleaning port 12. The two baffles 15 are respectively placed movably on the tops of the corresponding support rods 13. Through the support of the support rods 13, the load of the baffles 15 is increased, which does not prevent the normal detection of the strength of the concrete sample. At the same time, because the support rods 13 are cylindrical, it does not prevent the falling of the concrete debris.

[0029] Further, an outlet 21 is opened on the front side of the detection table 1. Two limit grooves 3 are opened at the bottom of the outlet 21. Limit plates 5 are slidably sleeved in the limit grooves 3. The two limit plates 5 are both fixedly connected to the bottom of the chip collecting box 2. The chip collecting box 2 is slidably sleeved in the outlet 21, which is convenient for guiding the chip collecting box 2 and is also conducive to pulling out the chip collecting box 2 to clean the concrete debris inside.

[0030] In the present utility model, during use, a concrete specimen is placed within the retaining frame 10 and on two baffle plates 15. The output shafts of two lower air cylinders 9 drive the two clamping plates 11 to approach each other, thereby clamping and fixing the concrete specimen on both sides, preventing shaking and affecting the accuracy of test data. The upper air cylinder 7 drives the extrusion head 8 to move downward to perform strength testing on the concrete specimen. The crushed concrete blocks are blocked by the retaining frame 10, causing the crushed concrete blocks to stay within the cleaning opening 12 above the retaining frame 10 and the baffle plates 15, preventing them from scattering everywhere and being difficult to clean. The upper and lower air cylinders are started in reverse, causing the extrusion head 8 and the clamping plates 11 to reset. Personnel remove the whole concrete specimen, start the servo motor 4, and the servo motor 4 drives the rotation of a double-headed screw 16. Through the transmission of two sprockets 17 and a chain 18, the synchronous rotation of the two double-headed screws 16 is driven. The two double-headed screws 16 drive the four sliding seats 19 and the two baffle plates 15 to retract away from each other into the cavity 14, without blocking the cleaning opening 12. At this time, the crushed concrete debris falls from the cleaning opening 12 into the chip collection box 2 for collection and processing. Through the support of the support rod 13, the load of the baffle plate 15 is increased, without interfering with the normal strength testing of the concrete specimen. At the same time, since the support rod 13 is cylindrical, it does not interfere with the falling of the concrete debris, thereby achieving the purpose of self-cleaning. The top of the baffle plate 15 enters into the cavity 14 and abuts against the top of the cavity 14, achieving the purpose of cleaning the top of the baffle plate 15 and preventing debris from adhering to the top of the baffle plate 15 and being unfavorable for the next use. After cleaning is completed, the servo motor 4 is started in reverse, causing the two baffle plates 15 to approach each other and abut. At this time, the cleaning opening 12 can be completely blocked by the two baffle plates 15 for use in strength testing of the next concrete specimen.
