[0002] Concrete is an artificial stone material made by mixing and hardening cement, aggregates, water, admixtures, and additives in a certain proportion. Durable concrete, on the other hand, is concrete that can resist physical, chemical, and biological effects in specific environments within its design service life to maintain structural safety and function. It must have properties such as impermeability, frost resistance, and chemical erosion resistance. It is suitable for harsh scenarios such as marine engineering, frigid regions, and chemical industrial parks. Compared with ordinary concrete, it pays more attention to long-term performance and environmental adaptability, which can extend the structural life and reduce maintenance costs.

[0003] To verify the rationality of the mix proportion of durable concrete and ensure that its strength, impermeability, frost resistance, and erosion resistance meet the design requirements, durable concrete is usually made into square test blocks to facilitate various performance tests.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-4 This utility model provides a technical solution: A durable concrete compaction device includes a vibration assembly, which includes a vibration motor body 1. The vibration motor body 1 is screwed to the top center of a vibrating plate 2. Four sets of guide rods 3 are fixedly installed around the top of the vibrating plate 2. The guide rods 3 are slidably engaged with guide seats 4. The guide seats 4 are located in the middle of a lifting plate 5 and are fixedly connected to the lifting plate 5. A limit plate 9 is fixedly installed on the top of the guide rods 3. A spring 10 is slidably sleeved on the surface of the guide rods 3. The top of the spring 10 abuts against the bottom of the guide seat 4, and the bottom of the spring 10 abuts against the vibrating plate 2. The guide seat 4 passes through the lifting plate 5. A damping sleeve 12 is provided between the inner wall of the guide seat 4 and the guide rods 3. The damping sleeve 12 is slidably engaged with the guide rods 3 and is bonded to the inner wall of the guide seat 4. The damping sleeve 12 is made of polyurethane material.

[0018] By setting up a vibration assembly, the function is to drive the vibrating plate 2 to vibrate through the vibrating motor body 1, thereby ensuring uniform compaction of the concrete inside the mold box and preventing cavities or incomplete pouring of the test block. Simultaneously, the vibrating plate 2 can cover the top opening of the mold box to prevent mud and water from splashing out and contaminating the experimental environment. Furthermore, the cooperation of the guide rod 3, spring 10, and damping sleeve 12 during vibration guides and reduces vibration transmission, ensuring the stability and reliability of the device. By setting up spring 10, when the vibrating motor body 1 starts and drives the vibrating plate 2 to vibrate at high frequency, the spring 10 and guide rod 3 can effectively alleviate the rigid impact of the vibrating plate 2 on the lifting plate 5 and the entire device structure, preventing loosening, wear, or even damage of components due to continuous strong vibration, thus extending the lifespan of the device. The lifespan of the device; the elastic characteristics of spring 10 help adjust the pressure between the vibrating plate 2 and the mold box, so that it maintains a suitable contact force during vibration, ensuring that the concrete can be fully compacted; by setting the damping sleeve 12, direct contact between the guide rod 3 and the guide seat 4 can be avoided, thereby reducing vibration transmission. The damping sleeve 12 absorbs and disperses the excess energy generated during vibration through its own flexible material, further reducing the transmission of vibration to other parts, avoiding adverse effects on components such as the lead screw 7 and the moving frame 8 due to resonance, and ensuring the normal operation of the adjustment component and the moving component; in addition, the damping sleeve 12 can also play a role in wear protection, preventing direct friction between the guide rod 3 and the guide seat 4, reducing component wear, and improving the stability and reliability of the device operation.

[0019] It also includes an adjustment assembly for adjusting the vertical position of the vibration component. The adjustment assembly includes a lifting plate 5, with movable seats 6 fixedly installed on the middle of both sides of the lifting plate 5. Two sets of movable seats 6 are respectively installed on the surfaces of two sets of lead screws 7. The top and bottom of the two sets of lead screws 7 are rotatably connected to the top and bottom of both sides of the movable frame 8, respectively. An active synchronous gear 11 is rotatably installed on one side of the top of the movable frame 8. The active synchronous gear 11 is coaxially arranged and fixedly connected to one of the sets of lead screws 7. A rotating handle 13 is fixedly installed on the top of the active synchronous gear 11. The step toothed wheel 11 is connected to the driven synchronous toothed wheel 15 via the synchronous toothed belt 14. The driven synchronous toothed wheel 15 is rotatably mounted on the other side of the top of the movable frame 8. The driven synchronous toothed wheel 15 is coaxially arranged with another set of lead screws 7. The driven synchronous toothed wheel 15 is fixedly connected to the top of the other set of lead screws 7. The two sides of the lifting plate 5 are slidably engaged with the two sides of the movable frame 8. The two sets of lead screws 7 have the same thread direction and model. The lead screw 7 model is: trapezoidal lead screw 7Tr32×6, with a trapezoidal tooth profile and a small thread helix angle, which has reliable self-locking performance.

[0020] By setting an adjustment component, the vertical position of the vibration component can be precisely controlled. The operator rotates the handle 13 on the top of the active synchronous toothed wheel 11, and the active synchronous toothed wheel 11 rotates accordingly. Its teeth mesh tightly with the grooves of the synchronous toothed belt 14, transmitting the rotational power to the driven synchronous toothed wheel 15 on the other side through the synchronous toothed belt 14. The driven synchronous toothed wheel 15 is also fixed coaxially with the lead screw 7, thereby driving the other set of lead screws 7 to rotate synchronously. This ensures that the speed and direction of the two sets of lead screws 7 are completely consistent, avoiding the problem of tilting or jamming of the lifting plate 5 caused by driving a single lead screw 7. The synchronous toothed belt 14 drives the driven synchronous toothed wheel 15, thereby causing the two sets of lead screws 7 to rotate synchronously, driving the lifting plate 5 to slide up and down along both sides of the moving frame 8, so that the vibration component can be accurately aligned with the mold box at different heights. This precise position adjustment ensures that the vibrating plate 2 can fit tightly against the top of the mold box, so that the vibration force generated by the vibrating motor body 1 can be effectively transmitted to the concrete, improving the compaction effect and enhancing the versatility and applicability of this device.

[0021] It also includes a moving component for moving the vibration assembly, the moving component including a moving frame 8, the bottom of which is fixedly mounted with casters 16.

[0022] By setting up a mobile component, its main function is to realize the flexible displacement of the vibration component. The universal wheels 16 installed at the bottom of the mobile frame 8 give the device convenient mobility. Operators can easily push the device to move quickly between different work positions and different mold boxes, which greatly reduces the manpower consumption of handling the vibration component, effectively improves work efficiency, and also provides a more flexible and efficient operating experience for concrete compaction operations.

[0023] In practical use, move the device to the designated position, push it directly above the mold box using the casters 16 at the bottom of the moving frame 8, align the vibrating plate 2 with the mold box, and rotate the handle 13 on the top of the active synchronous toothed wheel 11. The synchronous toothed belt 14 drives the two sets of lead screws 7 to rotate synchronously, causing the lifting plate 5 to slide downwards along both sides of the moving frame 8, pressing the bottom surface of the vibrating plate 2 firmly against the top surface of the mold box and compressing the spring 10. At this time, turn on the vibrating motor body 1 to drive the vibrating plate 2 to vibrate at high frequency. The vibrating plate 2 drives the mold box to vibrate, uniformly compacting the concrete. After compaction is completed, turn off the motor, rotate the handle 13 again to raise the vibrating component, and finally push the device to the next work station. The whole process is convenient to operate and can effectively improve the efficiency and quality of concrete test block production.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
