Description

Technical Field

[0001] This utility model relates to the field of concrete pumping technology, specifically to a concrete pouring device for building construction. Background Technology

[0002] In modern building construction projects, high-rise buildings have become the mainstream trend in urban development. As building heights continue to increase, concrete pumping technology, with its advantages of high efficiency, convenience, and continuous operation, has become a core technology for concrete pouring in high-rise buildings. A pumping system composed of concrete pump trucks, delivery pipes, and other equipment can transport concrete to high-altitude work surfaces, significantly improving construction efficiency and reducing labor costs.

[0003] However, pipeline blockage has always been a technical challenge in the pumped concrete construction process. To ensure the smooth transport of concrete within the pipeline, industry standards impose strict limits on the aggregate size of pumped concrete, requiring that the ratio of the maximum aggregate size to the inner diameter of the conveying pipeline be controlled within a certain range. However, in actual production, due to factors such as fluctuations in raw material quality, limitations in the precision of mixing equipment, and production management, it is difficult to completely avoid the mixing of oversized aggregates into the concrete. These aggregates exceeding the standard size are prone to accumulating at bends and diameter changes in the pipeline during concrete pumping. Because concrete is in a high-speed flowing state during pumping, once oversized aggregates cause local blockage, subsequent concrete, under pressure, will quickly form a larger accumulation near the blockage point, leading to complete blockage of the entire pumping pipeline and thus interrupting the concrete pouring operation.

[0004] Currently, conventional measures in the industry to address pipeline blockage mainly include optimizing concrete mix proportions, strengthening raw material inspection, and manually cleaning blocked pipelines. While optimizing concrete mix proportions can improve concrete fluidity to some extent, it cannot fundamentally eliminate the impact of oversized aggregates. Strengthening raw material inspection can reduce the probability of oversized aggregates being mixed in, but due to limitations in testing equipment and efficiency, it is difficult to achieve 100% accurate detection. Manually cleaning blocked pipelines is not only time-consuming and labor-intensive, but also causes construction delays and increases construction costs. In addition, the risks of high-pressure residual concrete spraying during the cleaning process also pose safety hazards to construction workers. Utility Model Content

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] Please see Figure 1-4 This utility model provides a technical solution:

[0026] A concrete pouring device for building construction includes a concrete pump truck, a pump pipe expansion frame, and a delivery pump pipe. Multiple sets of anti-blocking devices 1 are installed on the delivery pump pipe, and these devices are fixedly installed downstream of the pump pipe elbow connection. Concrete flow downstream of the pump pipe elbow connection is prone to blockage due to changes in direction and flow velocity.

[0027] Furthermore, the pump pipe anti-blocking device 1 includes a cylindrical base 2, a fixed flange 3, a convex structural cavity 4, and a vibration generating component 5. The cylindrical base 2 is a steel cylinder, and the inner diameter of the cylindrical base 2 is larger than the outer diameter of the delivery pump pipe. The cylindrical base 2 is sleeved on the delivery pump pipe. A fixed flange 3 is provided at one end of the cylindrical base 2. A convex structural cavity 4 is provided at the location away from the center of the cylindrical base 2. The vibration generating component 5 is installed inside the convex structural cavity 4.

[0028] Furthermore, a mating flange 6 is provided on the delivery pump pipe, and the fixing flange 3 and the mating flange 6 are fixedly connected by bolts. The pump pipe anti-blocking device 1 is fixedly installed on the delivery pump pipe through the mating flange 6. The flange connection method allows for fixation in multiple directions and can prevent vibration from causing the device to loosen and fall off the delivery pump pipe.

[0029] Furthermore, the vibration generating component 5 includes a driving component and a vibration component. The driving component includes a motor 7, a driving wheel 8, a pulley 9, and a transmission belt 10. The motor 7 is fixedly installed at the bottom of the convex structural cavity 4. The output end of the motor 7 is coaxially connected to the driving wheel 8. A pulley 9 is provided on one side of the driving wheel 8. The transmission belt 10 is sleeved on the outer side of the driving wheel 8 and the pulley 9. The driving wheel 8 and the pulley 9 are connected by transmission belt 10. A pulley fixing rod 11 is provided on one side of the pulley 9. The pulley 9 and the pulley fixing rod 11 are connected by bearings. The two ends of the pulley fixing rod 11 are welded to the convex structural cavity 4. A wire through hole is opened on the convex structural cavity 4. It is recommended to use wires for energy transmission and signal control. The wires can be fixed on the delivery pump pipe.

[0030] Furthermore, the diameter of pulley 9 is larger than that of the driving pulley 8. The design of pulley 9 having a larger diameter than the driving pulley 8 allows, according to the principle of transmission ratio, the smaller driving pulley 8 driving the larger pulley 9 to rotate, which can convert the high-speed rotation of the driving pulley 8 into a larger torque rotation of the pulley 9, thus enabling the vibration component to obtain stronger and more stable power.

[0031] Furthermore, the vibration assembly includes an eccentric column 12, an eccentric connecting rod 13, a sliding rail 14, a slider 15, a striking rod 16, and an elastic striking head 17. An eccentric column 12 is positioned on the side of the pulley 9 opposite to the pulley fixing rod 11. The eccentric connecting rod 13 is rotatably connected to the eccentric column 12. A sliding rail 14 is located at the other end of the eccentric connecting rod 13, and a slider 15 is slidably engaged within the sliding rail 14. The end of the eccentric connecting rod 13 is rotatably connected to the slider 15. A striking rod 16 is located at the bottom of the slider 15, and an elastic striking head 17 is located at the end of the striking rod 16. Driven by the slider 15, the elastic striking head 17 at the end of the striking rod 16 continuously strikes the outer wall of the delivery pump pipe at a high frequency. The vibration generated by this striking is transmitted to the inside of the delivery pump pipe. When the concrete flows through the downstream area of ​​the pump pipe bend, the vibration effectively breaks down the blockage structure formed by the concrete due to viscosity and aggregate accumulation, promoting the redispersibility of concrete particles and maintaining the fluidity of the concrete. Meanwhile, the elastic striking head 17 acts as a buffer during the striking process, ensuring sufficient striking force while avoiding damage to the delivery pump pipe caused by rigid striking, thus extending the service life of the delivery pump pipe.

[0050] Working Principle: The entire pouring system uses a concrete pump truck as its power core, transporting concrete to the pouring location via a delivery pump pipe. The pump pipe extension frame assists in adjusting the position and angle of the delivery pump pipe to meet the needs of different pouring scenarios. The pump pipe anti-blocking device 1 is installed downstream of the pump pipe elbow connection, a critical location where concrete flow is prone to blockage due to changes in direction and velocity. The pump pipe anti-blocking device 1 consists of multiple functional components working in tandem. Its basic structure, a cylindrical steel cylinder 2, has an inner diameter larger than the outer diameter of the delivery pump pipe. It is fitted onto the delivery pump pipe via a sleeve connection. A fixed flange 3 at one end is tightly fixed to a mating flange 6 on the delivery pump pipe using bolts. This installation method ensures a stable connection between the device and the delivery pump pipe while facilitating disassembly and maintenance. The convex structural cavity 4 at the back of the cylindrical foundation 2 provides installation space for the internal vibration generating component 5. The vibration generating component 5 is the core of the anti-blocking system, consisting of a drive component and a vibration component. The motor 7 in the drive component is installed at the bottom of the convex structural cavity 4, serving as the power source for the entire vibration system. The driven wheel 8, coaxially connected to the output end of the motor 7, begins to rotate at high speed after the motor 7 starts. A pulley 9, located on one side of the driven wheel 8, is connected to it via a transmission belt 10 fitted over both. To enhance transmission efficiency and increase vibration frequency, the diameter of the pulley 9 is designed to be larger than that of the driven wheel 8. Based on the transmission ratio principle, when the smaller driven wheel 8 drives the larger pulley 9, the high-speed rotation of the driven wheel 8 is converted into a larger torque rotation of the pulley 9, resulting in a stronger and more stable power for the vibration assembly. The pulley fixing rod 11 is welded to the convex cavity 4 at both ends. The bearing-connected pulley fixing rod 11 ensures the stability of the pulley 9 during rotation, preventing vibration effects caused by wobbling. When the pulley 9 rotates, the eccentric column 12 on the side opposite to the pulley fixing rod 11 performs circular motion. The eccentric connecting rod 13, rotatably connected to the eccentric column 12, converts the circular motion of the eccentric column 12 into linear reciprocating motion. The other end of the eccentric connecting rod 13 is rotatably connected to the slider 15 within the sliding track 14. The slider 15 can slide freely within the sliding track 14, thereby precisely transmitting the movement of the eccentric connecting rod 13 to the striking rod 16 below. The elastic striking head 17 at the end of the striking rod 16, driven by the slider 15, continuously strikes the outer wall of the conveying pump pipe at a high frequency. The vibration generated by this striking is transmitted to the inside of the conveying pump pipe. When concrete flows through the downstream area of ​​the pump pipe bend, the vibration effectively breaks down the blockage structure formed by the concrete due to viscosity and aggregate accumulation, promoting the redispersibility of concrete particles and maintaining the fluidity of the concrete. Simultaneously, the elastic striking head 17 acts as a buffer during the striking process, ensuring sufficient striking force while avoiding damage to the conveying pump pipe due to rigid striking, thus extending the service life of the conveying pump pipe. Throughout the entire operation, the pump pipe anti-blocking device 1 is linked with the power output of the concrete pump truck and the concrete flow in the conveying pump pipe.The concrete pump truck continuously pumps concrete into the delivery pump pipe. The pump pipe anti-blocking device 1 monitors in real time and prevents blockage by vibrating and tapping the pump pipe. The pump pipe telescopic frame flexibly adjusts the position of the delivery pump pipe. The three work together to ensure that the concrete pouring work of building construction is carried out efficiently and stably, effectively avoiding problems such as pouring interruption, concrete waste and reduced construction efficiency caused by pump pipe blockage, and providing a strong guarantee for the smooth progress of building construction.
