Description

Technical Field

[0001] The utility model relates to the technical field of concrete strength detection, in particular to an improved concrete strength detection device. Background Technique

[0002] In the field of construction engineering, concrete is widely used as a core material, and its quality is directly related to the stability and safety of buildings. Therefore, after the construction is completed, accurate detection of concrete strength is particularly important. This process relies on professional concrete strength detection devices. These devices apply pressure under simulated actual working conditions to concrete specimens and use scientific methods to evaluate and determine their strength coefficients. This detection method is not only efficient and accurate but also can provide timely and reliable data support for engineers to ensure that the concrete strength meets or exceeds the design standards, thus guaranteeing the safety and durability of the entire engineering structure.

[0003] Most of the existing concrete strength detection devices lack effective protection mechanisms. When applying pressure to the concrete to detect its strength, the debris generated by the fragmentation of concrete test blocks often splashes uncontrollably in all directions, which not only increases the safety risks for operators but also may cause pollution to the working environment. Moreover, after each test, due to the lack of an automatic cleaning structure, operators often need to manually remove the residual debris and concrete residues on the test bench, which is not only time-consuming and laborious but also greatly reduces the overall detection efficiency.

[0004] Therefore, those skilled in the art have provided an improved concrete strength detection device to solve the problems raised in the above background technique. Content of the Utility Model

[0005] The purpose of the utility model is to propose an improved concrete strength detection device to solve the deficiencies in the prior art. When the hydraulic cylinder squeezes the concrete, the hydraulic cylinder will drive two protections to move synchronously, thereby avoiding the splashing of debris during the test. When the protection frame is opened, it will drive the support plate to move, so that the debris on its upper end will automatically fall to the lower end of the test bench, realizing automatic cleaning operation and improving work efficiency.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] The improved concrete strength detection device includes a device main body. A hydraulic cylinder is fixedly arranged at the upper end of the device main body. A fixed block is fixedly arranged outside the output end of the hydraulic cylinder. Connecting blocks are rotatably arranged on both sides of the fixed block. Protection frames are rotatably arranged at the upper ends of the two connecting blocks. A base is fixedly arranged at the lower end of the device main body. A test bench is fixedly arranged on the upper end of the base.

[0008] Inside the test bench, a cleaning mechanism is provided. The cleaning mechanism includes a telescopic rod, a support plate, a mounting rod, a connecting rod, a sliding groove, a first pushing block, a second pushing block, a limiting strip, a moving groove, a limiting plate, a compression spring, a return spring, a limiting block, and a rotating block;

[0009] Through the above technical solution, when the hydraulic cylinder at the upper end of the device body extends, it will drive the fixed block at its output end to extend, causing the fixed block to drive the connecting block to rotate, so that the protective frame moves along with the connecting block, thereby providing safety protection for the testing process. When the protective frame is opened, the connecting rod will drive the support plate to displace inside the test bench, and the movement of the support plate will cause the concrete residue attached to it to automatically fall below the test bench. Through the opening and closing actions of the protective frame, the automatic cleaning function of the test tabletop is realized, improving work efficiency.

[0010] Further, one side of the telescopic rod is fixedly arranged inside one side of the two protective frames, the output end of the telescopic rod is fixedly arranged on one side of the second pushing block, the outside of the second pushing block is slidably arranged inside the support plate, and the outside of the support plate is slidably arranged inside the test bench;

[0011] Through the above technical solution, when the two protective frames move, one of them will drive the telescopic rod to move. When the telescopic rod moves to a preset position, the telescopic rod will drive the second pushing block to move inside the support plate, and then drive the support plate to slide inside the test bench.

[0012] Further, the outside of the first pushing block is slidably arranged inside the support plate, the front end of the first pushing block is fixedly arranged at the rear end of the limiting plate, the moving groove is externally opened at the front end of the upper end of the limiting plate, the front end of the limiting plate is fixedly arranged at the rear end of the compression spring, the front end of the compression spring is fixedly arranged inside the support plate near the front end, and the outside of the limiting plate is slidably arranged inside the support plate near the rear end;

[0013] Through the above technical solution, when the compression spring rebounds, it will cause the first pushing block and the limiting plate to move inside the support plate. When the limiting plate moves to a predetermined position, the moving groove opened at its upper end will fit inside the support plate, thus facilitating the movement of the support plate.

[0014] Further, one side of the mounting rod is fixedly arranged inside one side of the other of the two protective frames, one side of the connecting rod is rotatably arranged on the other side of the mounting rod, the other side of the connecting rod is rotatably arranged on the upper end of the rotating block, and the outside of the rotating block is slidably arranged inside the sliding groove;

[0015] Through the above technical solution, when the two protective frames move, they will drive the mounting rod to move, causing the connecting rod to move along with it, and further causing the rotating block at its lower end to slide inside the sliding groove.

[0016] Further, the front end of the return spring is fixedly arranged at the rear end inside the sliding groove, the rear end of the return spring is fixedly arranged at the front end of the limiting strip, one side of the limiting strip is rotatably arranged at one side inside the sliding groove, and the outside of the limiting block is fixedly arranged at the front end inside the sliding groove;

[0017] Through the above technical solution, when the limiting strip rotates, it will squeeze the return spring, causing it to contract inside the sliding groove, and the limiting block can prevent the limiting strip from rotating in the reverse direction inside the sliding groove.

[0018] Further, a pressing block is fixedly arranged at the output end of the hydraulic cylinder, and moving blocks are fixedly arranged at the upper ends of the two protective frames. The outside of the two moving blocks are both slidably arranged at the lower end inside the device main body;

[0019] Through the above technical solution, the hydraulic cylinder applies pressure to the concrete specimen through the pressing block to achieve strength testing. When the protective frame moves, the moving block at its upper end will slide inside the device main body and play a guiding role, making the movement of the protective frame stable.

[0020] Further, a collection box is slidably arranged inside the test bench, and a control panel is fixedly arranged on one side of the device main body;

[0021] Through the above technical solution, the concrete fragments after testing will automatically fall into the collection box, which is convenient for cleaning and disposal, and the control panel is convenient for the operator to operate.

[0022] The utility model has the following beneficial effects:

[0023] 1. For the improved concrete strength detection device proposed by the utility model, when detecting the concrete strength, by activating the hydraulic cylinder at the upper end of the device main body, its output end pushes the fixed block and the pressing block connected thereto to move downward. As the fixed block moves, the connecting blocks on both sides thereof will rotate, thereby driving the protective frames to move inward from both sides of the device main body. When the protective frames move to the set positions, they will protect the test area, effectively preventing the splashing of concrete fragments during the test, protecting the safety of the operator and the device, and reducing the impact on the working environment.

[0024] 2. For the improved concrete strength detection device proposed by the present utility model, as the hydraulic cylinder retracts, the protective frame will automatically unfold, driving the mounting rod and the connecting rod to move. The connecting rod will drive the rotating block to slide in the chute inside the support plate. When the rotating block slides to a certain position, it will be blocked by the limiting plate, and then the rotating block will drive the support plate to slide inside the test bench, thereby scraping off the debris and concrete residue on its upper end. As the protective frame continues to open, the telescopic rod also gradually reaches its final position. At this time, the output end of the telescopic rod will exert a thrust on the second pushing block, causing it to slide inside the support plate and gradually releasing the extrusion of the second pushing block on the first pushing block. The compressed compression spring will push the limiting plate to slide inside the support plate until it reaches the set position, enabling the rotating block originally restricted by it to be freed from the moving groove on the limiting plate, and then sliding back to its original position inside the chute. At the same time, due to the continuous action of the second pushing block, the support plate will slide inside the test bench and finally return to its initial position, making full preparations for the next test work. The entire operation process not only reduces manual operation, lowers the labor intensity, but also realizes the automatic cleaning operation of the debris. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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 the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Referring to Figures 1-6 , an embodiment provided by the present invention:

[0035] An improved concrete strength detection device includes a device main body 1. A hydraulic cylinder 4 is fixedly arranged at the upper end of the device main body 1. A fixed block 10 is fixedly arranged outside the output end of the hydraulic cylinder 4. Connecting blocks 12 are rotatably arranged on both sides of the fixed block 10. Protection frames 5 are rotatably arranged at the upper ends of the two connecting blocks 12. A base 3 is fixedly arranged at the lower end of the device main body 1. A test bench 7 is fixedly arranged at the upper end of the base 3. A pressing block 11 is fixedly arranged at the output end of the hydraulic cylinder 4. Moving blocks 9 are fixedly arranged at the upper ends of the two protection frames 5. The outsides of the two moving blocks 9 are slidably arranged inside the lower part of the device main body 1. A control panel 2 is fixedly arranged on one side of the device main body 1;

[0036] When testing concrete specimens, the operator activates the hydraulic cylinder 4 at the upper end of the device body 1 by operating the control panel 2. The control panel 2 provides an interface for the operator to interact with the device body 1, improving the convenience and safety of operation. The activated hydraulic cylinder 4 extends its output end, causing the pressing block 11 to apply pressure to the concrete specimen located on the test bench 7 to test its compressive strength. When the output end of the hydraulic cylinder 4 extends, it will drive the fixed block 10 outside it to move synchronously. The movement of the fixed block 10 will drive the connecting block 12 to rotate. Since the connecting block 12 is connected to the protective frame 5, the protective frame 5 will be moved, and the moving block 9 at its upper end will slide inside the device body 1, enabling the protective frame 5 to move smoothly. When the protective frame 5 moves to the preset position, a firm safety barrier will be formed, effectively isolating the possible flying debris during the test, providing comprehensive safety protection for the operator, creating a safe working environment for the entire test process, avoiding potential safety hazards, and ensuring the smooth progress of the concrete strength detection operation.

[0037] A cleaning mechanism 6 is arranged inside the test bench 7. The cleaning mechanism 6 includes a telescopic rod 601, a support plate 602, a mounting rod 603, a connecting rod 604, a sliding groove 605, a first pushing block 606, a second pushing block 607, a limiting strip 608, a moving groove 609, a limiting plate 610, a compression spring 611, a return spring 612, a limiting block 613, and a rotating block 614. One side of the telescopic rod 601 is fixedly arranged on one side inside one of the two protective frames 5. The output end of the telescopic rod 601 is fixedly arranged on one side of the second pushing block 607. The outside of the second pushing block 607 is slidably arranged inside the support plate 602. The outside of the first pushing block 606 is slidably arranged inside the support plate 602. The outside of the support plate 602 is slidably arranged inside the test bench 7. The front end of the first pushing block 606 is fixedly arranged on the rear end of the limiting plate 610. The moving groove 609 is externally opened at the front end of the upper end of the limiting plate 610. The front end of the limiting plate 610 is fixedly arranged on the rear end of the compression spring 611. The front end of the compression spring 611 is fixedly arranged inside the support plate 602 near the front end. The outside of the limiting plate 610 is slidably arranged inside the support plate 602 near the rear end. One side of the mounting rod 603 is fixedly arranged on one side inside the other of the two protective frames 5. One side of the connecting rod 604 is rotatably arranged on the other side of the mounting rod 603. The other side of the connecting rod 604 is rotatably arranged on the upper end of the rotating block 614. The outside of the rotating block 614 is slidably arranged inside the sliding groove 605. The front end of the return spring 612 is fixedly arranged inside the sliding groove 605 near the rear end. The rear end of the return spring 612 is fixedly arranged on the front end of the limiting strip 608. One side of the limiting strip 608 is rotatably arranged inside the sliding groove 605 near one side. The outside of the limiting block 613 is fixedly arranged inside the sliding groove 605 near the front end. A collection box 8 is slidably arranged inside the test bench 7;

[0038] When the protective frame 5 moves as the output end of the hydraulic cylinder 4 retracts, the mounting rod 603 installed inside the protective frame 5 drives the connecting rod 604 to move, prompting the rotating block 614 at the lower end of the connecting rod 604 to slide in the chute 605 inside the support plate 602. When the rotating block 614 slides to a certain position, it will be blocked by the limiting plate 610, and then the rotating block 614 drives the support plate 602 to slide inside the test bench 7, so that the debris on the upper end of the test bench 7 is scraped off, and the concrete residue and debris after the test will automatically fall into the collection box 8 inside the test bench 7, realizing automatic cleaning, reducing the need for manual cleaning, improving work efficiency, making the test process more continuous and efficient, and at the same time keeping the working environment clean. As the protective frame 5 moves, the output end of the telescopic rod 601 on one side will reach the final position. At this time, the output end of the telescopic rod 601 will drive the second push block 607 to slide inside the support plate 602. The movement of the second push block 607 will gradually relieve the extrusion on the first push block 606, causing the compression spring 611 to gradually extend, and will drive the limiting plate 610 connected to it to slide inside the support plate 602. When the limiting plate 610 slides to the predetermined position, the rotating block 614 will slide out from the inside of the moving groove 609 opened on the limiting plate 610, and then the rotating block 614 will squeeze the limiting strip 608 inside the chute 605, causing it to squeeze the return spring 612, so that the rotating block 614 returns to its original position. At the same time, the movement of the second push block 607 will drive the support plate 602 to slide on the test bench 7, making the support plate 602 return to its original position. When the protective frame 5 moves inward, the limiting strip 608 and the limiting block 613 will block the rotating block 614, causing it to slide near the front end of the chute 605, thus facilitating full preparation for the next detection.

[0039] Working principle: When detecting the strength of concrete, start the hydraulic cylinder 4, and its output end drives the pressing block 11 to move downward, precisely applying pressure to the concrete specimen placed on the test bench 7, so as to scientifically test the compressive strength of the concrete. The extension of the output end of the hydraulic cylinder 4 will synchronously drive the fixed block 10 to move, causing the connecting blocks 12 on both sides to rotate and prompting the protective frame 5 to move inside the device main body 1. When the protective frame 5 moves to the preset position, the protective frame 5 can isolate the splashing of debris generated during the test, thereby providing a safety protection function. As the output end of the hydraulic cylinder 4 retracts, the protective frame 5 will automatically open, prompting the installation rod 603 to move synchronously and driving the connecting rod 604 to link. The connecting rod 604 drives the rotating block 614 to slide in the chute 605 on the support plate 602 inside the test bench 7. When the rotating block 614 slides along the chute 605 to a specific position, it will be blocked by the limit plate 610, which not only restricts the movement of the rotating block 614 but also prompts it to drive the support plate 602 to slide inside the test bench 7, thereby scraping off the debris and concrete residues on the upper end of the support plate 602 and making them automatically fall into the collection box 8 located inside the test bench 7, thus realizing the automatic cleaning operation of the test bench 7. As the protective frame 5 continues to move, the telescopic rod 601 will gradually reach its final position. At this time, the output end of the telescopic rod 601 pushes the second pushing block 607 to slide inside the support plate 602, thereby gradually releasing the extrusion of the second pushing block 607 on the first pushing block 606, causing the originally compressed compression spring 611 to gradually release energy and extend outward. The elastic force of the compression spring 611 pushes the limit plate 610 to slide backward inside the support plate 602 until it reaches the predetermined position. When the limit plate 610 slides to this position, the rotating block 614 originally restricted by the limit plate 610 is released from the moving groove 609, allowing the rotating block 614 to smoothly slide out of the chute 605 and return to its original position. At the same time, due to the continuous movement of the second pushing block 607, the support plate 602 will slide reversely inside the test bench 7 and finally return to its initial position, preparing for the next test.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. 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 described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
