Description

Technical Field

[0001] The present invention relates to the technical field of concrete pouring, and in particular to concrete pouring equipment based on big data analysis. Background Art

[0002] In construction projects, concrete pouring is a key process, and its quality is directly related to the stability and durability of the entire structure. With the development of the Internet of Things, big data, and intelligent sensing technology, combining real-time sensor data collection with big data analysis models has become an important direction for improving the quality and efficiency of concrete construction.

[0003] In the existing technology, traditional equipment is generally unable to collect and feedback analyze key parameters such as temperature, humidity, fluidity, and vibration frequency during the concrete pouring process in real time, and can only rely on the operator's experience for manual judgment and control. This method has a reaction lag, which can easily lead to insufficient or excessive vibration, uneven distribution or cold joints between layers, and then cause voids, segregation or looseness inside the concrete, affecting the structural strength and durability. In addition, traditional equipment usually relies on manual sampling to detect slump, which has problems such as detection lag, process interruption and large error, and cannot achieve real-time monitoring and dynamic adjustment, resulting in low discharge efficiency, uncontrolled concrete state, and easy occurrence of construction defects such as pipe blockage, segregation, and water seepage.

[0021] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to specific embodiments.

[0023] like Figures 1 to 9As shown, the concrete pouring equipment based on big data analysis includes a mounting frame 1, a mixing chamber 2 is arranged above the mounting frame 1, and the mixing chamber 2 is used to accommodate concrete raw materials; a feeding assembly, the feeding group is arranged above the mixing chamber 2, and the feeding assembly is used to transmit the original force of the proportion to the internal mixing assembly of the mixing chamber 2, the mixing assembly is arranged inside the mixing chamber 2, and the mixing assembly includes two mixing rods 6 rotatably installed inside the mixing chamber 2, and the two mixing rods 6 are provided with a number of staggered mixing blades 7; a driving assembly, the driving assembly is arranged on one side of the mounting frame 1, and the driving assembly is used to drive the mixing assembly to rotate; a vibrating assembly, the vibrating assembly includes a mixing and vibrating module and an auxiliary vibrating module, the mixing and vibrating module is embedded in the mixing rod 6, the mixing and vibrating module is used to vibrate the concrete during mixing, and the auxiliary vibrating modules are distributed on the inner side of the mixing chamber 2, and the auxiliary vibrating module is used to vibrate bubbles or density during concrete processing; a sensor group, the sensor group includes a side wall temperature and humidity sensor 18 deployed on the side of the inner side of the mixing chamber, a bottom surface of the inner bottom of the mixing chamber A temperature and humidity sensor 19, a torque sensor on the stirring rod 6, and a fluidity detection sensor group arranged on the discharge pipe; a control unit, the control unit includes a mounting rod 21 fixedly mounted on a corner of the mounting frame 1, a control box 24 is provided on the mounting rod 21, the control unit is used to receive real-time data from the sensor group, and dynamically adjust the rotation speed of the stirring assembly and the frequency of the vibration assembly, wherein one side of the two stirring rods 6 is arranged through the stirring bin 2, and the two stirring rods 6 are provided with a second transmission gear 8 on one side that passes through the stirring bin 2, the driving assembly includes a driving motor 3 and a transmission box 4, the output end of the driving motor 3 is connected to one side of the transmission box 4 with a belt transmission, and the other side of the transmission box 4 is provided with two output ends, and the two output ends of the transmission box 4 are provided with a first transmission gear 5 respectively meshed with the two stirring blades 7, a cover plate 14 is provided above the stirring bin 2, and a positioning frame 15 is provided on one side of the stirring bin 2, the feeding assembly includes a feed hopper 16 arranged on the top of the positioning frame 15, and the bottom of the feed hopper 16 is provided with a guide plate 17 corresponding to the feeding port of the stirring rod 6; After the equipment is started, the raw materials flow into the mixing bin 2 through the positioning frame 15 and the feed hopper 16 according to the guide plate 17, the driving motor 3 drives the transmission box 4 to output rotation, and the two stirring rods 6 start to rotate through the meshing transmission gears, driving the staggered stirring blades 7 to forcibly stir the concrete raw materials. At the same time, the stirring and vibrating modules embedded in the stirring rods 6 start to work, generating high-frequency vibrations to release bubbles inside the mixture and improve fluidity. The auxiliary vibration module synchronously vibrates the concrete on the wall of the mixing bin 2 to enhance the molding density; the sensor group continuously collects data such as temperature, humidity, torque and flow rate and transmits them to the control unit. The control unit dynamically adjusts the stirring speed and vibration frequency according to the preset algorithm to adapt to changes in concrete proportion, temperature and humidity conditions and mixing resistance to ensure that the discharged concrete meets the quality standards. Finally, after mixing is completed, it is sent to the subsequent pouring link through the discharge hole 11.

[0024] like Figures 4 to 7 As shown, the stirring and vibrating module includes a plurality of stirring vibrators 25 embedded in the stirring rod 6, and the stirring vibrators 25 are axially spaced along the stirring rod 6. The auxiliary vibrating module includes a plurality of bonding plates 9 bonded to the inner wall of the stirring chamber 2, and the outer surfaces of the plurality of bonding plates 9 are smooth. Side wall vibrators 10 are provided inside the plurality of bonding plates 9. Each side wall vibrator 10 and the stirring vibrator 25 include at least two orthogonally arranged piezoelectric ceramic vibrators. The operating frequency range of the stirring vibrator 25 is 20kHz-50kHz, and the frequency difference between adjacent stirring vibrators 25 is ≥5kHz, which is used to generate an interference vibration field during the stirring process. The operating frequency range of the side wall vibrator 10 is 10kHz-30kHz. When the stirring vibrator 25 is in the high-frequency mode, the side wall vibrator 10 is synchronously switched to the low-frequency mode to form a high-low frequency coupled vibration field. High-frequency vibration (20kHz-50kHz) is generated by multiple axially spaced stirring vibrators 25 (containing orthogonal piezoelectric ceramic vibrators) embedded in the stirring rod 6, which directly acts on the concrete during the mixing process; the auxiliary vibration module generates relatively low-frequency vibration (10kHz-30kHz) through the side wall vibrator 10 (also containing orthogonal piezoelectric ceramic vibrators) attached to the smooth bonding plate 9 on the inner wall of the mixing bin 2, which acts on the contact area between the concrete and the bin wall. The advantage is that the high-frequency vibration of the stirring vibrator 25 can effectively break up cement particle agglomerates, release mixing water and eliminate tiny bubbles, and the frequency difference between adjacent vibrators ≥5kHz is 0. The frequency difference design can generate an interference vibration field, enhancing the uniformity and coverage of vibration energy transfer within the concrete and avoiding the formation of vibration dead zones. The low-frequency vibration of the side wall vibrator 10 helps overcome the adhesion between the concrete and the silo wall, reducing segregation and promoting the discharge of bubbles near the silo wall. More importantly, when the stirring vibrator 25 is in high-frequency mode, the side wall vibrator 10 synchronously switches to low-frequency mode, forming a high-low frequency coupled vibration field. This synergistic effect can more efficiently address problems at different scales (microscopic bubbles and macroscopic fluidity). High frequency targets micronization, while low frequency improves overall fluidity, significantly improving vibration efficiency and concrete homogeneity, and reducing internal defects. The outer surfaces of the side wall vibrator (10) and the stirring vibrator (25) are provided with a wear-resistant layer (26), and the wear-resistant layer 26 is a tungsten carbide and cobalt-based composite material with a thickness of 0.2-0.5 mm; The stirring vibrator 25 is directly embedded in the stirring rod 6 and is exposed to a high-speed rotating concrete environment filled with hard aggregate (sand and gravel). Its working principle requires it to withstand severe friction and impact. To this end, a wear-resistant layer 26 composed of high-hardness, high-wear-resistant tungsten carbide and good-toughness cobalt-based composite material is provided on its outer surface. The thickness is controlled at 0.2-0.5mm. The benefits are obvious. This composite wear-resistant layer 26 can effectively resist the continuous scratching and impact wear of the aggregate in the concrete on the vibrator surface, greatly extending the service life of the stirring vibrator 25, ensuring the long-term reliable operation of the high-frequency vibration function under harsh working conditions, and avoiding the decline in vibration effect or equipment failure due to vibrator wear and failure.

[0025] like Figures 2 to 7 As shown, two discharge holes 11 are respectively provided on one side of the bottom of the mixing bin 2. The discharge pipe includes a connecting pipe 12 corresponding to the two discharge holes 11. A common pipe 13 is provided on the other side of the two connecting pipes 12. The fluidity detection sensor group includes an ultrasonic flow meter 28 provided on one side of the connecting pipe 12 and a pressure pulsation sensor 20 provided on one side of the common pipe 13. The control unit calculates the slump prediction value using the following formula: Wherein, T is the torque of stirring rod 6, v is the discharge flow rate, P is the pressure pulsation amplitude, 、 is the calibration coefficient; The control unit dynamically adjusts the activation strategy of the vibrating assembly according to the slump prediction value S as follows: When S< When the oscillator 10 on the inner side wall of the mixing chamber 2 close to the discharge pipe is activated first; When S> When , the stirring speed is reduced and the high-frequency micro-vibration mode of the stirring vibrator 25 is triggered; The concrete outflow velocity (v) is measured using ultrasonic flowmeters 28 installed at key locations on the discharge port 11, and the pressure fluctuation amplitude (P) at the common pipe 13 is measured using a pressure pulsation sensor 20. This is combined with the stirring resistance torque (T) measured in real time by the torque sensor on the stirring rod 6. The core of the control unit is the application of the empirical formula: The three real-time physical quantities (T, v, and P) are integrated and calculated to produce a predicted slump value (S). This value comprehensively reflects the consistency, fluidity, and uniformity of concrete. Its advantage is that it enables online, indirect, and rapid assessment of concrete workability, replacing the hysteresis of traditional offline slump tests. Based on the predicted value S, the control unit implements an intelligent vibration strategy: When S is low (concrete is too thick and has poor fluidity), the sidewall vibrator 10 near the discharge hole 11 is preferentially activated. This has the advantage of focusing on vibrating the key area (near the discharge port) with the worst fluidity and prone to blockage, effectively unblocking and improving discharge smoothness. When S is high (concrete is too thin and prone to segregation), the mixing speed is reduced to reduce shear damage, and the high-frequency micro-vibration mode of the mixing vibrator 25 is triggered. This has the advantage of using high-frequency micro-vibration to more finely bridge potential segregation gaps, evenly distribute components, eliminate tiny bubbles, and prevent segregation from worsening. This achieves precise and adaptive vibration control based on the real-time state of the concrete, significantly improving pouring quality and efficiency.

[0026] like Figure 1 、 Figure 8 As shown, the top of the mounting rod 21 is also provided with an external temperature and humidity sensor 22 and a wind speed sensor 23; The external temperature and humidity sensor 22 and wind speed sensor 23 mounted on top of the mounting rod 21 work by continuously monitoring the ambient temperature, humidity, and wind speed surrounding the mixing equipment. This provides the control unit with important environmental operating parameters. Ambient temperature and humidity directly affect the evaporation rate and setting time of concrete, while wind speed exacerbates this effect (especially at high wind speeds). After integrating these environmental data, the control unit can more comprehensively assess the concrete state (for example, combining internal temperature and humidity with predicted slump values). This data can be used to optimize mixing parameters (such as fine-tuning the amount of water added), vibration strategies, or to warn of potential problems (such as accelerated water loss on hot and windy days, which increases the risk of plastic cracking). This allows for more refined intelligent control that adapts to environmental changes, improving the construction adaptability and ultimate quality stability of concrete under various climatic conditions.
