Abstract
Description
Technical Field
[0001] This utility model relates to the field of building engineering technology, and in particular to a concrete construction device. Background Technology
[0002] Concrete construction equipment is a series of mechanical devices specifically designed for concrete construction, encompassing various types such as mixers, mixer trucks, pump trucks, shotcrete machines, and vibrators. Mixers are responsible for uniformly mixing cement, aggregates, water, and admixtures in specific proportions to create a concrete mix; mixer trucks transport the mix between the batching plant and the construction site, ensuring its stable performance; pump trucks can precisely deliver concrete along pipelines to high or distant locations for pouring; shotcrete machines are used to spray concrete at high speed onto the work surface in specific scenarios; and vibrators expel air from within the concrete during pouring, improving density and strength. These devices are used throughout the entire process of concrete construction, from preparation to completion, greatly improving construction efficiency, ensuring construction quality, and reducing labor costs, making them indispensable tools in modern construction engineering.
[0003] When a mixer in a concrete construction unit is working, the mechanical energy output from the power source is transmitted to the mixing shaft through a transmission device. The mixing shaft drives the mixing blades mounted on it to rotate at high speed, creating a strong mixing flow field inside the mixing drum. The mixing blades exert forces on the cement, sand, water, and admixtures inside the drum through convection, shearing, and diffusion. Convection causes the materials to circulate throughout the mixing drum, achieving a macroscopically uniform distribution; shearing utilizes the relative motion between the blades and the materials to break down and refine large particles, promoting contact and mixing between materials; diffusion allows material particles to interpenetrate and penetrate at the microscopic level, ultimately ensuring the uniform fusion of all material components to form a concrete mixture that meets construction requirements.
[0004] However, some existing concrete mixers suffer from inconvenient cleaning after use. The mixer's internal structure is complex, with various shapes and angles of mixing blades distributed along the drum wall. While these blades efficiently mix materials during the mixing process, they become major sources of concrete residue after use. Especially in narrow and hard-to-reach areas such as the angles between the blades and the drum wall, and the connection between the mixing shaft and the blades, concrete residue easily adheres and accumulates. Ordinary cleaning tools, limited by the internal structure, cannot thoroughly clean these hard-to-reach areas, resulting in significant time and labor costs for each cleaning session, and often unsatisfactory cleaning results. This severely impacts the mixer's subsequent efficiency and lifespan. Therefore, a concrete construction device is proposed to address these problems. Utility Model Content

[0024] 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.
[0025] Reference Figures 2 to 4This utility model provides an embodiment of a concrete construction device, comprising multiple support frames 1, with connecting frames 2 fixedly connected to adjacent support frames 1. When the device is subjected to external force, the connecting frames 2 can evenly distribute the force to each support frame 1, thereby enhancing the overall deformation resistance of the device. A housing 3 is fixedly connected to adjacent sides of the multiple support frames 1. A slide rail 4 is fixedly connected to the front side of two support frames 1, and a slide rail 5 is fixedly connected to the front side of two support frames 1. The slide rail 5 and slide rail 4 cooperate with each other, enabling components connected to sliders 6 and 7 respectively to move in different directions or in coordination, greatly enriching the device's movement modes and functions. A slider 6 is slidably connected inside slide rail 4. When subjected to external force, slider 6 can slide along the length of slide rail 4 under the constraint of slide rail 4.
[0026] The slide rail 25 has a sliding connection to a slider 2 7. The sliding of slider 2 7 allows the connected components to move accordingly. In practical applications, slider 2 7 and slider 1 6 work together to enable precise position adjustment and motion control of the equipment in different directions, providing a foundation for more complex functions. A connecting shaft 1 8 is fixedly connected to the front of slider 1 6. When slider 1 6 slides within slide rail 1 4, connecting shaft 1 8 drives support block 1 9 to move synchronously. Support block 1 9 is fixedly connected to the front exterior of connecting shaft 1 8. When connecting shaft 1 8 moves with slider 1 6, support block 1 9 provides a stable support surface for the components placed on it. A moving block 10 is fixedly connected to the front of slider 2 7. Similar to connecting shaft 1 8, the movement of slider 2 7 is transmitted to moving block 10 through a fixed connection, allowing moving block 10 to move along with slider 2 7 within slide rail 2 5. A connecting block 11 is fixedly connected to the top of moving block 10. When moving block 10 moves, connecting block 11 drives the connected components to move synchronously.
[0027] Connecting block 11 is securely connected to moving block 10, transmitting the movement of moving block 10 to subsequent components. A rotating shaft 12 is rotatably connected to the top of connecting block 11. As connecting block 11 moves with moving block 10, rotating shaft 12 can rotate relative to it within connecting block 11 as needed. A telescopic column 13 is fixedly connected to the outside of rotating shaft 12. When rotating shaft 12 rotates, telescopic column 13 rotates accordingly and can extend or retract as needed. A telescopic assembly for extension and retraction is fixedly connected to the top of support block 9, and a stabilizing assembly for stability is fixedly connected to the bottom of telescopic support frame 1.
[0028] Reference Figures 3 to 5The stabilizing component includes multiple contraction shells 29, the tops of which are fixedly connected to the bottoms of multiple support frames 1. Each support frame 1 has a damping column 30 fixedly connected to its bottom. When the equipment vibrates, the damping column 30 is compressed or stretched. The internal damping material hinders this rapid deformation, converting the mechanical energy of the vibration into heat or other forms of energy, thus dissipating the vibration energy. A spring 31 is fitted around the outside of the damping column 30. When the equipment vibrates, the spring 31 undergoes compression or stretching deformation outside the damping column 30. During vibration, the spring 31 can store and release energy, working in conjunction with the damping column 30. A vibration damping pad 35 is fixedly connected to the bottom of the damping column 30. When the equipment exerts force on the ground due to vibration or other external forces, the vibration damping pad 35 can absorb and disperse these forces through its own deformation. The external fixed connection of the shrink shell 29 is a limiting block 32. During the expansion and contraction of the shrink shell 29, the limiting block 32 can ensure that the connected parts will not be excessively displaced or fall off due to the expansion and contraction of the shrink shell 29.
[0029] Multiple limiting blocks 32 are rotatably connected to connecting shafts 2 and 33 on opposite sides. When the equipment tilts or vibrates, the damping rod 34 can rotate on the limiting blocks 32 via the connecting shafts 2 and 33, changing its angle to adapt to changes in the equipment's posture. The damping rod 34 is externally fixed to the connecting shafts 2 and 33. When the equipment tilts or sways, the damping rod 34 is subjected to force due to the change in the equipment's posture. The internal damping material hinders its rapid oscillation, suppressing the equipment's sway by consuming mechanical energy. When the equipment tilts to one side, the damping rod 34 will oscillate accordingly under the drive of the connecting shafts 2 and 33. The damping force generated by the internal damping material will resist this oscillation, thereby slowing down the tilting speed of the equipment.
[0030] The bottom end of the damping rod 34 is fixedly connected to a connecting shaft 36. When the damping rod 34 swings due to changes in the equipment's posture, the connecting shaft 36 allows the limiting block 37 to adjust its angle according to the actual situation, better adapting to the connection requirements between the equipment and the chassis 38. This connection method ensures the flexibility of the connection between the limiting block 37 and the damping rod 34, enabling the entire stabilizing assembly to adaptively adjust according to the actual movement state of the equipment during operation, thus improving the efficiency and reliability of the stabilizing assembly. The connecting shaft 36 is externally rotatably connected to the limiting block 37. When the damping rod 34 drives the connecting shaft 36 to move, the limiting block 37 can flexibly adjust its angle on the connecting shaft 36 according to changes in the equipment's posture and the direction of movement of the damping rod 34. The bottom end of the limiting block 37 is fixedly connected to the chassis 38. When the equipment is placed on the ground, the chassis 38 increases the contact area between the equipment and the ground, reducing the pressure of the equipment on the ground and preventing the equipment from sinking into soft ground due to excessive pressure.
[0031] Reference Figures 1 to 3 The telescopic assembly includes a connecting block 3 16, the bottom of which is fixedly connected to the top of the support block 1 9. A rotating shaft 3 17 is fixedly connected inside the top of the connecting block 3 16. When the equipment needs to adjust the angle of the telescopic column 2 21, the telescopic column 2 21 can rotate smoothly around the rotating shaft 3 17. The advantage of this design is that it gives the telescopic column 2 21 flexible angle adjustment capability, allowing the equipment to precisely adjust the direction of the telescopic column 2 21 according to different working scenarios and needs, thereby improving the equipment's adaptability to complex working environments. The telescopic column 2 21 is externally rotatably connected to the rotating shaft 3 17. When the equipment needs to adjust the working height or working distance, the telescopic column 2 21 can extend or shorten through the relative sliding of its internal sleeve.
[0032] The top of the telescopic column 21 is internally connected to a rotating shaft 20. When the telescopic column 21 rotates or extends, the connecting block 19 can adjust its angle around the rotating shaft 20 accordingly. The external of the rotating shaft 20 is fixedly connected to the connecting block 19. When the rotating shaft 20 rotates, the connecting block 19 drives the support block 18 to rotate as well, and stably transmits the telescopic force when the telescopic column 21 extends. The left side of the connecting block 19 is fixedly connected to the support block 18, providing a stable support platform for the connecting rod 22 and related components above. This platform evenly distributes the weight of the connecting rod 22 and other components onto the connecting block 19, and then transmits it to the telescopic column 21 and other structures. The top of the support block 18 is fixedly connected to the connecting rod 22. When the equipment is operating, the connecting rod 22 stably supports components such as the leak-proof pad 23, ensuring they function normally in their respective positions.
[0033] A leak-proof pad 23 is fixedly connected to the right side of the connecting rod 22. In work scenarios where liquid or gas leaks are possible, the leak-proof pad 23 provides a seal, preventing liquid or gas from leaking out from the connection between the connecting rod 22 and related components. A limit block 24 is fixedly connected to the top of the connecting rod 22. When the telescopic column 25 rotates around the connection point outside the top of the limit block 24, the limit block 24 restricts its rotation angle, preventing excessive rotation of the telescopic column 25 and potential equipment damage or malfunction. The telescopic column 25 is rotatably connected to the outer top of the limit block 24. When the equipment needs further adjustment of its working height or range of action, the telescopic column 25 can rotate under the limit of the limit block 24, and can also extend or retract according to work requirements. A limit block 26 is rotatably connected to the inner right end of the telescopic column 25, providing a stable connection and rotational support for the retractable rod 27, while limiting the range of motion of the retractable rod 27 to prevent excessive swinging or displacement.
[0034] A retractable lever 27 is fixedly connected to the bottom end of the limiting block 26. When the equipment needs to operate on a specific area, the retractable lever 27 can retract or extend according to actual needs to adapt to different working distance requirements. Multiple nozzles 28 are fixedly connected to the outside of the retractable lever 27. A rotating shaft 14 is fixedly connected to the inside of the top of the telescopic column 13. When the equipment needs to adjust the angle of the connecting block 15, the connecting block 15 can rotate smoothly around the rotating shaft 14. The connecting block 15 is rotatably connected to the outside of the rotating shaft 14. When the rotating shaft 14 rotates, the connecting block 15 can drive the connected components to rotate together, and stably transmit the telescopic force when the telescopic column 13 extends and retracts. The rear side of the support block 9 is slidably connected to the front side of the slider 6. When the slider 6 slides within the slide rail 4 under the action of external force, the support block 9 can move along with the slider 6 through the sliding connection between its rear side and the slider 6. The rear side of the movable block 10 is slidably connected to the front side of the slide rail 2 5.
[0035] When an external force is applied to the movable block 10, the movable block 10 can slide along the guide rail on the front side of the slide rail 2 5. The top end of the connecting block 2 15 is fixedly connected to the bottom end of the support block 1 9, connecting the support block 1 9 and the connecting block 2 15 into a whole, so that the support block 1 9 can drive the connecting block 2 15 to move together during the movement of the device, and at the same time, transmit the force between the two during the operation of the equipment. The external sliding connection of the connecting shaft 1 8 is slidably connected to the inner wall of the slide rail 1 4. When the slider 1 6 slides in the slide rail 1 4, the connecting shaft 1 8 can slide on the inner wall of the slide rail 1 4 accordingly, and during the sliding process, it provides a stable guiding effect for the support block 1 9 and the components connected to it. The bottom end of the vibration damping pad 35 is fixedly connected to the top of the chassis 38. When the equipment is placed on the ground, the vibration damping pad 35 can form a buffer layer between the chassis 38 and the ground. When the equipment exerts a force on the ground due to vibration or other external forces, the vibration damping pad 35 can absorb and disperse these forces through its own deformation, reduce the rigid contact between the equipment and the ground, and prevent vibration energy from being reflected back to the equipment through the ground, causing secondary vibration.
[0036] The spring 31 is externally slidably connected to the inside of the contraction shell 29. When the equipment is subjected to vibration, the spring 31 will undergo compression or stretching deformation inside the contraction shell 29. During vibration, the spring 31 can store and release energy, working in conjunction with the damping column 30. The top end of the vibration damping pad 35 is fixedly connected to the bottom end of the contraction shell 29. When the damping column 30 moves up and down due to equipment vibration, the vibration damping pad 35 can buffer the impact force of the damping column 30 on the contraction shell 29, preventing damage to the contraction shell 29 due to hard impact. The bottom end of the spring 31 is fixedly connected to the top end of the vibration damping pad 35. In the equipment vibration damping system, after the bottom end of the spring 31 is connected to the vibration damping pad 35, the elastic force generated by the spring 31 during vibration can be effectively transferred to the vibration damping pad 35, thereby transferring and dispersing energy through the vibration damping pad 35.
[0037] Working Principle: In the cleaning structure of this concrete mixer, slider 6 slides within slide rail 4, driving the connecting shaft 8 and support block 9 to move. The movement of support block 9, in turn, causes connecting block 2 15 and connecting block 3 16 to move accordingly. Slider 2 7 slides within slide rail 2 5, driving the moving block 10 and connecting block 11 to move. Connecting block 11, via rotating shaft 12, drives telescopic column 13 to rotate. Telescopic column 13, via rotating shaft 2 14, cooperates with connecting block 2 15, further influencing the overall movement. Connecting block 3 16, via rotating shaft 3 17, drives telescopic column 21 to rotate. Telescopic column 21, via rotating shaft 4 20, drives connecting block 4 19 and support block 2 18 to move. Support block 2 18 drives connecting rod 22, leak-proof pad 23, and limiting block 1 24 to move. Limiting block 1 24 drives telescopic column 3 25 to rotate. Telescopic column 3 25, via limiting block 2 26, drives retraction function rod 27 and multiple nozzles 28 to move. By sliding the slider within the slide rail and coordinating the rotation and extension of each connecting structure, the nozzle can clean the interior of the housing 3 at different angles.
[0038] When the mixer vibrates during operation, the support frame 1 transmits the vibration to the damping column 30. The damping column 30, under the action of the spring 31, extends and retracts, and the vibration-damping pad 35 at its bottom further buffers the vibration. Simultaneously, the support frame 1 drives the shrink shell 29 to move. The shrink shell 29, through the limiting block 32, drives the connecting shaft 23 to rotate. The connecting shaft 23 drives the damping rod 34 to swing. The damping rod 34, through the connecting shaft 36, drives the limiting block 47 to move, and the limiting block 47 drives the chassis 38 to finely adjust its position. Through the coordinated movement of the damping column 30, spring 31, and damping rod 34, stable support for the mixer is achieved, effectively reducing vibration.
