Description

Technical Field

[0001] This utility model relates to the field of concrete conveying technology, specifically to an anti-clogging device for ultra-high concrete pumping pipelines. Background Technology

[0002] With the rapid advancement of modern urbanization, large-scale and super-large-scale construction projects are springing up like mushrooms after rain. Ultra-high-precision concrete pumping technology plays a crucial role in these magnificent projects. Whether it's towering skyscrapers, massive bridge projects, or uniquely designed large stadiums, all rely heavily on the powerful support of ultra-high-precision concrete pumping technology.

[0003] In the construction of skyscrapers, concrete needs to be transported hundreds of meters into the air to meet the construction requirements of different floors. Similarly, in bridge construction, long-span bridge structures require precise pumping of concrete to designated locations to ensure the stability of the bridge structure. The construction of large stadiums, due to their complex spatial structures and enormous size, also places extremely stringent requirements on concrete pumping. The application of ultra-high-precision concrete pumping technology has enabled the successful construction of these complex building structures, greatly propelling the construction industry towards higher and more complex applications.

[0004] Pump speed is a critical control parameter in concrete pumping. When the pump speed is too high, the concrete flows at high speed within the pumping pipeline, generating immense pressure on the pipeline's inner wall. This pressure comes not only from the concrete's own weight but also from the impact force generated during pumping. As the pump speed increases, the pressure within the pipeline rises sharply. Once this pressure exceeds the pipeline's withstand limit, a pipe rupture is highly likely. A pipe rupture not only leads to massive concrete leakage and waste of raw materials but also severely impacts construction progress. More dangerously, at the construction site, a pipe rupture can directly threaten the lives of construction workers, causing serious safety accidents. For example, in some high-rise building construction projects, leaked concrete from a burst pipe can fall from a height, potentially injuring workers and damaging equipment below. Conversely, a pump speed that is too slow can also cause a series of serious problems, the most prominent being the accumulation of large aggregates leading to pipeline blockage. Concrete is a mixture composed of cement, aggregates, water, and admixtures. During pumping, if the pump speed is too slow, the flow rate of concrete within the pipeline decreases, making it easier for larger aggregates to settle and accumulate within the pipeline. Over time, these accumulated aggregates will gradually form blockages, hindering the normal delivery of concrete. Once the pipes are blocked, construction must be interrupted, requiring a significant amount of time and manpower to clear the pipes. This not only delays the construction schedule and increases construction costs, but may also cause the pipes to solidify due to prolonged exposure to concrete, rendering them unusable and resulting in substantial economic losses for the construction project.

[0005] Because precise control of pump speed is difficult during concrete pumping, problems such as pipe bursts and blockages caused by excessively fast or slow pumping speeds severely hinder the smooth progress of engineering construction. To ensure the safe and efficient operation of ultra-high concrete pumping, the development of a technology or device that can effectively solve these problems is urgently needed. The emergence of an anti-blockage device for ultra-high concrete pumping pipelines is precisely to address this challenge. Through innovative design and a unique working principle, it is expected to solve the pipeline blockage problem caused by improper pumping speed, ensure smooth concrete pumping, improve construction efficiency, reduce construction costs, and provide a solid technical guarantee for the smooth progress of modern engineering construction.

[0030] 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.

[0031] Please see Figures 1-5 This utility model provides a technical solution:

[0032] A high-strength concrete pumping pipeline anti-clogging device includes a structural sleeve 1 and a pumping pipeline 2. Flanges 3 are machined at both ends of the pumping pipeline 2. The structural sleeve 1 is fitted onto the pumping pipeline 2. Two sets of protective side plates 4 are provided on both sides of the structural sleeve 1, and an annular protective shell is provided between the two sets of protective side plates 4. Fixing holes corresponding to the flanges 3 are machined on the protective side plates 4. The structural sleeve 1 is fixedly installed on the pumping pipeline 2 through the flanges 3. The device is characterized by further including: a motion mechanism 5, which is disposed between the two sets of protective side plates 4 on the structural sleeve 1, and the motion mechanism 5 moves to provide the basis for vibration; a vibration generating mechanism 6, which is disposed on the structural sleeve 1, and the vibration generating mechanism 6 cooperates with the motion mechanism 5 to achieve the vibration function; a vibration rod return mechanism 7, which is disposed on both sides of the vibration generating mechanism 6 on the structural sleeve 1, and the vibration rod return mechanism 7 is used to return the components of the vibration generating mechanism 6, enabling periodic vibration of the device; and a power mechanism 8, which is disposed on the structural sleeve 1, and the power mechanism 8 is used to drive the motion mechanism 5.

[0033] Furthermore, the motion mechanism 5 includes an eccentric ring protrusion block 9 and an eccentric rotating ring 11. The eccentric ring protrusion block 9 is located inside the structural sleeve 1, and a rotating groove 10 coaxial with the structural sleeve 1 is formed on the eccentric ring protrusion block 9. The rotatable eccentric rotating ring 11 is housed within the rotating groove 10. The power mechanism 8 is the power source for the entire device. After the motor 18 on one side of the structural sleeve 1 starts, the friction wheel 19, coaxially connected to the output end of the motor 18, begins to rotate. The friction wheel 19 is frictionally connected to the friction groove 23 on the rotating mating part 22 of the eccentric rotating ring 11, using friction to drive the eccentric rotating ring 11 to rotate within the rotating groove 10 of the eccentric ring protrusion block 9. Because the rotating groove 10 is coaxial with the structural sleeve 1, the eccentric rotating ring 11 can stably perform circular motion, providing continuous power support for the vibration function.

[0034] Furthermore, the eccentric rotating ring 11 includes an annular base 20, an eccentric portion 21, and a rotating mating portion 22. The eccentric portion 21 is provided on one side of the annular base 20, and the rotating mating portion 22 is provided on the axial side of the annular base 20. A friction groove 23 is provided on the rotating mating portion 22. The unique structure of the eccentric rotating ring 11 is the key to realizing the vibration function. The eccentric rotating ring 11 is composed of an annular base 20, an eccentric portion 21, and a rotating mating portion 22. When the eccentric rotating ring 11 rotates in the rotating groove 10, its eccentric portion 21 makes a circular motion as it rotates. A vibration rod limiting groove 13 is provided on the protrusion of the eccentric ring convex structure block 9, and a vibration rod 12 is slidably engaged in the groove. During the rotation of the eccentric rotating ring 11, the eccentric portion 21 gradually approaches and abuts against the vibration rod 12. As the eccentric rotating ring 11 continues to rotate, the eccentric portion 21 pushes the vibration rod 12 to move away from the pumping pipe 2 along the vibration rod limiting groove 13. During this process, movement and collisions occur between the various structures, resulting in vibrations. These vibration waves are transmitted through the structural sleeve 1 and related components to the central pumping pipe 2, causing the pumping pipe 2 to vibrate.

[0035] Furthermore, the vibration generating mechanism 6 includes a vibration rod 12 and a vibration rod limiting groove 13. The vibration rod limiting groove 13 is provided on the convex part of the eccentric ring convex structure block 9, and the vibration rod 12 is slidably engaged in the vibration rod limiting groove 13.

[0036] Furthermore, the vibration rod return mechanism 7 includes a base block 14, a slider 16, and a return spring 17. A slider 16 is provided at the end of the vibration rod 12. A base block 14 is provided on the inner side of the protective side plate 4 corresponding to the vibration rod 12. A groove 15 corresponding to the slider 16 is formed on the base block 14. The slider 16 is slidably engaged within the groove 15. A return spring 17 is installed on the side of the groove 15 away from the axis. One end of the return spring 17 abuts against the base block 14, and the other end abuts against the slider 16. When the eccentric part 21 pushes the vibration rod 12 away from the pumping pipe 2, the slider 16 slides synchronously within the groove 15 and compresses the return spring 17. As the eccentric part 21 continues to rotate with the eccentric rotating ring 11 and gradually moves away from the vibration rod 12, the return spring 17 releases its elastic force due to elastic deformation, pushing the slider 16 to slide towards the pumping pipe 2 within the groove 15, thereby causing the vibration rod 12 to return to a position close to the pumping pipe 2 along the vibration rod limiting groove 13. In this way, as the eccentric rotating ring 11 continues to rotate, the vibrating rod 12 is constantly pushed and reset, realizing the periodic vibration of the device.

[0037] Furthermore, the power mechanism 8 includes a motor 18 and a friction wheel 19. The motor 18 is provided on one side of the structural sleeve 1, and the output end of the motor 18 is coaxially connected to the friction wheel 19. The friction wheel 19 is in frictional connection with the friction groove 23.

[0062] Working Principle: During ultra-high concrete pumping, larger aggregates in the concrete within the pumping pipeline 2 can easily accumulate, leading to pipeline blockage. This anti-blockage device uses a power mechanism 8 to drive a motion mechanism 5, which in turn drives a vibration generating mechanism 6 to produce vibration. The vibration is then transmitted periodically to the pumping pipeline 2 via a vibration rod recovery mechanism 7. This continuous periodic vibration effectively prevents the accumulation of larger aggregates within the pumping pipeline 2, maintaining good fluidity of the concrete within the pipeline and ensuring the smooth operation of ultra-high concrete pumping, while also improving construction safety. Furthermore, by adjusting the speed of the motor 18, the rotational speed of the friction wheel 19 can be changed, thereby adjusting the rotational speed of the eccentric rotating ring 11, achieving flexible adjustment of the vibration frequency to adapt to different construction conditions and concrete characteristics. The power mechanism 8 is the power source for the entire device. After the motor 18, located on one side of the structural sleeve 1, starts, the friction wheel 19, coaxially connected to the output end of the motor 18, begins to rotate. The friction wheel 19 is frictionally connected to the friction groove 23 of the rotating engagement part 22 on the eccentric rotating ring 11, using friction to drive the eccentric rotating ring 11 to rotate within the rotating groove 10 of the eccentric ring convex structural block 9. Since the rotating groove 10 is coaxial with the structural sleeve 1, the eccentric rotating ring 11 can stably perform circular motion, providing continuous power support for the vibration function. The unique structure of the eccentric rotating ring 11 is key to achieving the vibration function. The eccentric rotating ring 11 consists of an annular base 20, an eccentric part 21, and a rotating engagement part 22. When the eccentric rotating ring 11 rotates within the rotating groove 10, its eccentric part 21 performs circular motion accordingly. A vibration rod limiting groove 13 is provided on the convex part of the eccentric ring convex structural block 9, and a vibration rod 12 is slidably engaged within the groove. During the rotation of the eccentric rotating ring 11, the eccentric part 21 gradually approaches and abuts against the vibration rod 12. As the eccentric rotating ring 11 continues to rotate, the eccentric part 21 pushes the vibrating rod 12 to move away from the pumping pipe 2 along the vibrating rod limiting groove 13. During this process, movement and collisions occur between the various structures, resulting in vibration. These vibration waves are transmitted to the central pumping pipe 2 through the structural sleeve 1 and related components, causing the pumping pipe 2 to vibrate. To enable the device to generate periodic multiple vibrations, the vibrating rod return mechanism 7 plays an important role. A slider 16 is provided at the end of the vibrating rod 12, and a groove 15 corresponding to the slider 16 is opened on the base block 14 on the inner side of the protective side plate 4 corresponding to the vibrating rod 12. The slider 16 is slidably engaged in the groove 15. When the eccentric part 21 pushes the vibrating rod 12 away from the pumping pipe 2, the slider 16 slides synchronously in the groove 15 and compresses the return spring 17. As the eccentric part 21 continues to rotate with the eccentric rotating ring 11 and gradually moves away from the vibrating rod 12, the return spring 17 releases the elastic force generated by the elastic deformation, pushing the slider 16 to slide in the groove 15 toward the direction of the pumping pipe 2, thereby driving the vibrating rod 12 to return to the position close to the pumping pipe 2 along the vibrating rod limiting groove 13.In this way, as the eccentric rotating ring 11 continues to rotate, the vibrating rod 12 is constantly pushed and reset, realizing the periodic vibration of the device.
