For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through the specific circumstances.

[0029] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This utility model provides a core drilling method for testing the strength of bricks, comprising:

[0031] Testing table 1 is equipped with a core drilling testing mechanism. It should be noted that the core drilling testing mechanism can be used in conjunction with the strength testing equipment. During strength testing, it can effectively prevent splashing and facilitate the emptying and cleaning of waste chips after the test is completed.

[0032] The core drilling inspection mechanism includes a pressing seat 9, a T-shaped splice 10, a placement box 11, a clamping block 13, a servo motor 14, a rotating shaft 15, and an insertion block 16;

[0033] The bottom of the extrusion seat 9 is fixedly connected to the T-shaped splice 10. It should be noted that the extrusion seat 9 is made of transparent material, which makes it easy to check the condition of the sample.

[0034] T-shaped splice 10 is snapped into the testing table 1, the placement box 11 is fixedly installed on the top of the testing table 1, the clamping block 13 is horizontally slidably installed on the placement box 11, the output end of the servo motor 14 is fixedly connected to the rotating shaft 15, the rotating shaft 15 is threadedly connected to the clamping block 13, the insert block 16 is fixedly connected to the clamping block 13, and the insert block 16 is snapped into the extrusion seat 9.

[0035] Through the aforementioned core drilling and testing mechanism, the servo motor 14 is activated to rotate the shaft 15, thereby causing the two clamping blocks 13 to move towards each other to clamp and limit the brick 12. Then, the core drilling machine 5 drills the brick 12 to obtain a core sample. After sampling, the brick 12 is removed and the sample is placed into the extrusion seat 9. Then, the sample strength is tested by the cooperation of the extrusion plate 8. After the extrusion plate 8 moves into the extrusion seat 9, it can fit against the inner wall of the extrusion seat 9, which can prevent waste chips from splashing. After the test is completed, the servo motor 14 can be activated to make the two clamping blocks 13 move towards each other, thereby causing the clamping blocks 13 to drive the insert block 16 to move, so that the insert block 16 separates from the extrusion seat 9. At this time, the extrusion seat 9 can be pulled forward to remove the extrusion seat 9 and pour out the waste chips for cleaning.

[0036] Specifically, the core drilling testing mechanism also includes a top frame 2, a hydraulic cylinder 3, a push plate 4, a core drilling machine 5, a vertical plate 6, a pressure sensor 7, and a pressing plate 8. The top frame 2 is fixedly installed on the top of the testing platform 1, the hydraulic cylinder 3 is fixedly installed on the top of the top frame 2, the hydraulic rod of the hydraulic cylinder 3 is fixedly connected to the push plate 4, the core drilling machine 5 is fixedly installed on the bottom of the push plate 4, the top of the vertical plate 6 is fixedly connected to the push plate 4, the bottom of the vertical plate 6 is fixedly connected to the pressure sensor 7, and the bottom of the pressure sensor 7 is fixedly connected to the pressing plate 8. It should be noted that the pressure sensor 7 is connected to an external controller to display the pressure reading.

[0037] The servo motor 14 is fixedly mounted on the top frame 2.

[0038] Through the aforementioned core drilling and testing mechanism, starting the hydraulic cylinder 3 can cause the extrusion plate 8 and the core drilling machine 5 to move down synchronously, allowing the core drilling machine 5 to perform core drilling work. The extrusion plate 8 and the pressure sensor 7 work together to perform strength testing. This allows the two devices to be combined effectively, making them convenient to use.

[0039] Specifically, the top of the testing table 1 is provided with a T-shaped splicing groove, and the T-shaped splicing piece 10 is engaged with the T-shaped splicing groove. The bottom of the extrusion seat 9 is in contact with the testing table 1. It should be noted that this facilitates the splicing of the extrusion seat 9.

[0040] Specifically, the rotating shaft 15 has a bidirectional thread on its outer side, and the clamping block 13 has a screw hole on its side. The bidirectional thread is threaded to the screw hole. A brick 12 is placed inside the placement box 11. The two clamping blocks 13 clamp and fix the brick 12. The rotating shaft 15 is rotatably mounted on the placement box 11. The rotating shaft 15 is located below the brick 12. A moving hole is opened on the side of the placement box 11. The clamping block 13 is slidably installed in the moving hole. An insertion hole 17 is opened on the side of the extrusion seat 9. The insertion block 16 is engaged with the insertion hole 17. It should be noted that when the two clamping blocks 13 approach each other and contact the outer side of the placement box 11, the insertion block 16 can be moved out of the insertion hole 17, releasing the restriction on the extrusion seat 9.

[0041] Specifically, the extrusion plate 8 is located directly above the extrusion seat 9. It should be noted that after the extrusion plate 8 is moved into the extrusion seat 9, it can fit against the inner wall of the extrusion seat 9, which can prevent waste chips from splashing.

[0042] Specifically, the push plate 4 is slidably sleeved on the outer side of the top frame 2, which allows the push plate 4 to move stably in the vertical direction.

[0043] Working principle:

[0044] S1: Place the brick 12 to be tested into the placement box 11, start the servo motor 14, and its output shaft drives the rotating shaft 15 to rotate. Since the outer side of the rotating shaft 15 is machined with bidirectional threads and is threadedly connected to the screw hole on the side of the clamping block 13, according to the principle of thread transmission, when the rotating shaft 15 rotates, the two clamping blocks 13 will move towards each other in the moving hole on the side of the placement box 11 until the brick 12 is firmly clamped and fixed in the placement box 11, providing a stable foundation for subsequent core drilling operations.

[0045] S2: Start hydraulic cylinder 3. The hydraulic rod of hydraulic cylinder 3 pushes push plate 4 to slide downward on the outside of top frame 2. The core drill 5, which is fixedly connected to push plate 4, moves down synchronously. When the core drill 5 descends to the appropriate position, it performs core drilling on the clamped and fixed brick 12 to drill a core sample for strength testing. During this process, by controlling the extension and retraction of the hydraulic rod of hydraulic cylinder 3, the descent depth of core drill 5 can be precisely controlled to ensure the quality of core drilling.

[0046] S3: After the core sampling is completed, the limit on the brick 12 is released, and the drilled core sample and the brick 12 are taken out. The drilled core sample is placed in the extrusion seat 9. The extrusion seat 9 is fixedly connected to the test table 1 by the T-shaped splicing piece 10 at the bottom and the T-shaped splicing groove at the top of the test table 1. At this time, the insert block 16 and the insert hole 17 on the side of the extrusion seat 9 are locked together to further fix the extrusion seat 9.

[0047] S4: Restart hydraulic cylinder 3, and the hydraulic rod continues to push push plate 4 downward, causing extrusion plate 8, which is connected to push plate 4 through vertical plate 6 and pressure sensor 7, to move into extrusion seat 9. Extrusion plate 8 gradually extrudes the core sample located in extrusion seat 9. During this process, pressure sensor 7 senses the pressure changes in real time during the extrusion process and transmits the pressure signal to the external controller connected to it, thereby displaying the pressure reading. As the extrusion proceeds until the core sample is crushed, the compressive strength of the core sample can be detected based on the data fed back by pressure sensor 7, and the actual strength of the brick can be inferred. At the same time, since extrusion plate 8 is attached to the inner wall of extrusion seat 9 after moving into extrusion seat 9, it can effectively prevent waste from splashing to the outside during the detection process.

[0048] S5: After the strength test is completed, start the servo motor 14 to reverse, so that the rotating shaft 15 rotates in the opposite direction. The two clamping blocks 13 move towards each other, causing the insert block 16 to separate from the insertion hole 17 on the side of the extrusion seat 9. At this time, the limit of the extrusion seat 9 is released, and the extrusion seat 9 can be pulled forward to remove it from the test table 1. Pour out the waste residue inside the extrusion seat 9 to complete the cleaning work, so as to carry out the next brick 12 strength test operation. The two devices can be combined well and are convenient to use.

[0049] The above provides a detailed description of the core drilling method for testing brick strength provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core idea of ​​this utility model.
