Description

Technical Field

[0001] This invention relates to the field of cement pole preparation technology, specifically to a centrifugal molding device for concrete cement poles. Background Technology

[0002] Concrete poles are key components widely used in power transmission and transformation lines, communication lines and contact network supports. Their production quality is directly related to the safety of line operation. The mainstream production process of cement poles is as follows: first, concrete is placed into a steel mold containing a steel reinforcement skeleton, and then the concrete is compacted by centrifugal molding to form a hollow ring structure. Then, steam curing is used to accelerate cement hydration, so that the pole can obtain demolding strength in a short time. Steam curing is the most energy-intensive and critical process in cement pole production, significantly impacting product quality. Currently, the industry commonly uses pit-type atmospheric pressure steam curing, where centrifugally formed cement poles are hoisted into a curing tank, steam is introduced, and valve opening and curing time are controlled manually based on experience. For example, Chinese patent application CN202010743395.X describes an intelligent production control system and method for cement poles, including: a production planning module, a steel reinforcement frame fabrication module, a batching and mixing module, a concrete delivery module, a centrifugation module, a steam curing module, a demolding module, a demolding module, a mold cleaning module, a resource management module, and a quality process control module. This system scientifically and rationally plans cement pole production and automatically collects production data to effectively control and adjust the process, reducing workload and ensuring production efficiency and product quality. The aforementioned steam curing module involves an operator moving the mold from the previous process, collecting information via an antenna, and feeding it back to the system. The system then automatically matches the corresponding chip code and checks if the previous process has already collected data. If so, it directly proceeds to the completion interface for that process; otherwise, it displays an error message and enters the error handling interface. This process collects time data twice: once for kiln opening and once for kiln closing, using preset times to determine the possibility of timeouts. However, in actual steam curing, factors affecting quality are not limited to time; temperature and humidity also play a role. Specifically, uneven temperature and humidity distribution within the steam curing tank leads to differences in the steam curing environment for cement poles at different locations within the same tank, resulting in variations in the overall quality of the steam-cured cement poles. Therefore, there is an urgent need for a centrifugal molding device for concrete cement poles. Summary of the Invention

[0003] In order to overcome the shortcomings of existing technologies and solve the technical problems raised in the background art.

[0004] This invention is achieved through the following technical solution: a centrifugal molding device for concrete cement poles, comprising a feeding module, a centrifugal module, and a steam curing module: The feeding module is used to fill the steel mold with concrete; The centrifugal module is used to drive the steel mold to rotate after the concrete is filled. The concrete is evenly and densely attached to the mold wall by the centrifugal force generated by the high-speed rotation inside the steel mold, and excess water is squeezed out, thus forming a hollow, high-strength ring rod. The steam curing module is used to receive the molded concrete cement rod after centrifugation. By constructing a data-driven closed-loop control system, the steam curing environment is dynamically adjusted so that the concrete can obtain sufficient strength for demolding in a very short time after centrifugation and dehydration.

[0005] Furthermore, the steam curing module consists of a steam curing tank, a sensor matrix, a historical dataset, a control unit, and an execution unit. Its core function is to generate an adaptive ventilation control strategy by integrating historical data with real-time parameters. The sensor matrix is ​​used to collect environmental factors affecting the cement hydration process and heat and moisture exchange efficiency in the steam curing tank in real time from multiple dimensions, and generate real-time environmental data vectors according to a preset cycle. The historical dataset stores a standard ambient temperature curve consisting of complete process records of a large number of successful steam curing cases. This curve defines the ideal mapping relationship of time, temperature, humidity, and pressure in four stages: static stop, uniform heating, constant temperature, and controlled cooling, as well as the standard temperature rise parameters for each stage. The standard ambient temperature curve data is shown below. It should be noted that during the cooling phase, the humidity gradually and naturally decreases from 100%, and may fall below 95% in the later stages. The control unit is used to dynamically compare the real-time environmental data vector with the standard environmental temperature curve, calculate the ventilation coefficient, and determine the actual power of the execution unit based on the ventilation coefficient. The execution unit is used to dynamically adjust the steam flow and circulation state within the steam curing tank under the drive of the control unit.

[0006] Furthermore, the sensor matrix consists of a temperature sensor subarray, a humidity sensor subarray, a pressure sensor subarray, and a hydration exothermic monitoring probe. The temperature sensor subarray consists of multiple temperature sensors arranged at intervals along the longitudinal and circumferential directions of the steam curing tank; a temperature measuring point is set every 1.5-2 meters along the length of the tank on the top inner wall, and corresponding points are simultaneously arranged at the bottom to capture vertical temperature stratification; a row of temperature measuring points is set at the middle height of each of the two side walls; at least one temperature measuring point is set in the adjacent area of ​​the end of the cement pole steel mold; and a temperature measuring point is set at the steam main inlet and the outlet of the steam trap. The humidity sensor subarray consists of capacitive humidity sensors; it is placed in the central area at the top of the steam curing tank along the length of the tank, 20-30 cm above the condensate accumulation areas on both sides of the bottom, and in the gap between the two cement rods in the middle of the tank. The pressure sensing subarray consists of micro differential pressure sensors; pressure tapping points are set at the top and bottom of the steaming tank to obtain the pressure difference between the inside and outside of the tank, and an atmospheric pressure reference tapping point is set outside the tank to measure the pressure difference between the inside and outside of the tank in real time. The hydration heat release monitoring probe consists of a semi-insulated temperature rise probe embedded in a benchmark concrete specimen. The benchmark specimen is placed at the farthest end from the steam inlet in the steam curing tank, representing the hydration process under the worst-case conditions. The probe is embedded in the center of the specimen, and the lead wire is connected to the control unit through a sealed wire hole in the tank wall.

[0007] Furthermore, the calculation logic of the control unit for calculating the ventilation coefficient and the actual power of the execution unit is as follows: S1. Based on the current system clock, determine the current stage of the steam curing process (static stop / uniform heating / constant temperature / controlled cooling), and extract the target value corresponding to the current moment from the standard ambient temperature curve stored in the historical dataset: target temperature. Target humidity Target pressure ; S2, Real-time temperature collected by the sensor matrix Real-time humidity Real-time pressure The temperature deviation is obtained by subtracting the corresponding target value one by one. , humidity deviation Pressure deviation ; S3. Divide each deviation value by the preset normalization reference value to obtain the dimensionless normalized deviation. , , ; S4. Next, the normalized deviations are multiplied by their corresponding weighting coefficients and summed. The temperature weight (Wt), humidity weight (Wh), and pressure weight (Wp) are set based on the sensitivity analysis of the impact of various environmental factors on the 28-day strength of cement poles in historical datasets, satisfying Wt + Wh + Wp = 1. This represents the comprehensive environmental deviation value. = *Wt+ *Wh+ *Wp; S5. Then, the absolute value of the comprehensive environmental deviation value is compared with the basic ventilation demand coefficient. Superimposed to generate ventilation coefficient ,Right now = + ,in This is a preset constant (usually taken as 0.15~0.20), representing the minimum ventilation requirement required to maintain steam microcirculation and prevent static dead zones even when the environment perfectly matches the standard curve; the calculation formula is the minimum operating frequency at which the fan can just eliminate the static dead zone / the rated frequency of the fan. S6, Finally, adjust the ventilation coefficient. Input a three-segment power mapping model to determine the final actual power of the wind turbine. The specific logic is as follows: when (Lower zone, environment basically conforms to standard curve) = ; when During the linear region (where environmental tolerances exist), the wind turbine power is calculated using linear interpolation. = +( - )* when (High-altitude area, severely deviated from the environment) = (Rated full power), and simultaneously trigger an alarm.

[0008] The actuator mainly consists of a fan, an electric regulating valve, and inlet and outlet air ducts. Driven by the actual power command output by the control unit, it regulates the steam flow and circulation state in the following ways: When the actual power received is the minimum cycle power, the fan operates at the minimum safe speed, the electric air valve opens to the minimum opening degree, only pushing the steam in the pool to flow slowly, maintaining a slightly positive pressure state, preventing the intrusion of external cold air, and avoiding the occurrence of a static dead zone.

[0009] When the actual power enters the linear adjustment zone, the fan speed increases synchronously with the increase in power, the opening of the air valve increases accordingly, the steam circulation intensity is enhanced, and the superheated steam at the top is forcibly transported to the low-temperature area at the bottom, eliminating temperature stratification and humidity dead zones.

[0010] When the actual power reaches the rated full power, the fan runs at full speed and the air valve is fully opened to forcibly agitate the steam in the pool with the maximum circulation volume, quickly correcting the severely deviated environmental parameters.

[0011] Furthermore, the setting logic for the temperature weight Wt, humidity weight Wh, and pressure weight Wp is as follows: Complete process records of numerous successful steam curing cases were extracted from historical datasets. Each record contains two types of data: environmental deviation data during the steam curing process, namely, temperature deviation during the steam curing process. , humidity deviation Pressure deviation (These are all root mean square or integral values ​​of the deviation at each sampling time, reflecting the cumulative deviation throughout the steam curing process); the corresponding quality result data is the measured 28-day compressive strength of this batch of cement poles; A combination of controlled variables and regression analysis was used to quantify the independent impact of each environmental deviation on the intensity. Temperature sensitivity analysis involves selecting a subset of cases from historical data where humidity and pressure deviations are relatively small (i.e., close to standard values). Only samples with significant temperature deviations are retained. A univariate regression analysis is conducted with temperature deviation as the independent variable and 28-day strength as the dependent variable to obtain the strength change rate corresponding to each unit change in temperature deviation (e.g., 1°C). This change rate, after normalization, becomes the temperature sensitivity coefficient. It should be noted that the main strength of the cement pole (approximately 100% of the design strength) is basically achieved at 28 days, with subsequent growth being extremely slow. Using this as an evaluation window reflects both the final mechanical potential of the concrete and provides an engineering-acceptable testing period.

[0012] Humidity sensitivity analysis: Select a subset of cases with small temperature and pressure deviations, and on the samples with significant humidity deviations, regress to obtain the rate of change of intensity corresponding to each unit change in humidity deviation (e.g., each deviation of 1% relative humidity), and normalize to obtain the humidity sensitivity coefficient. Pressure sensitivity analysis, on a subset of cases with small temperature and humidity deviations, regresses to obtain the rate of change of intensity corresponding to each unit change in pressure deviation (e.g., each deviation of 1 Pa), and normalizes to obtain the pressure sensitivity coefficient. Finally, the absolute values ​​of the three sensitivity coefficients are normalized so that their sum equals 1, thus obtaining the weight of each environmental factor; the temperature sensitivity coefficient Wt = Humidity sensitivity coefficient Wh= Pressure sensitivity coefficient Wp= .

[0013] Furthermore, the feeding module includes a feeding bracket, a semi-steel mold at the top of the feeding bracket, sealing discs fixed to both ends of the semi-steel mold, a spiral steel wire inside the semi-steel mold, multiple reinforcing bars inside the spiral steel wire, a pair of slide rails fixed to both ends of the feeding bracket, a slider slidably connected inside the slide rails, a threaded hole on the side of the slider, a lead screw engaged in the threaded hole, a control motor with its output end fixed to the end of the lead screw at the end of the slide rail; a first linkage frame fixed to the top of the slider, a first hydraulic cylinder mounted at the end of the first linkage frame, a second linkage frame fixed to the output end of the first hydraulic cylinder, a shaping template fixed to the end of the second linkage frame near the semi-steel mold, an arc-shaped notch at the top of the shaping template, a discharge cylinder inserted inside the arc-shaped notch, a tripod fixed to the bottom of the discharge cylinder, and a feeding assembly at the top of the discharge cylinder.

[0014] Furthermore, the feeding assembly includes a receiving cylinder, a hopper is fixedly connected to the top of the receiving cylinder, a connecting frame is fixedly connected to the inner wall of the receiving cylinder, the bottom end of the connecting frame is located inside the feeding cylinder, a receiving plate is fixedly connected to the bottom end of the connecting frame, a groove is provided on the side of the receiving plate, a centrifugal rod is inserted into the groove, a buffer spring is fixedly connected to one end of the centrifugal rod and the inner wall of the groove, and a scraper is fixedly connected to the other end of the centrifugal rod. A receiving frame is rotatably connected to the top of the feeding cylinder. A second hydraulic cylinder is fixedly connected to the top of the second linkage frame. The output end of the second hydraulic cylinder is fixedly connected to the receiving frame. A first toothed ring is fixedly connected to the top of the feeding cylinder. A first gear is meshed with the side of the first toothed ring. A second toothed ring is slidably connected to the top of the first toothed ring. A connecting rod is fixedly connected between the second toothed ring and the surface of the receiving cylinder. A second gear is meshed with the side of the second toothed ring. A pair of drive motors are installed at the bottom of the receiving frame. The output ends of the pair of drive motors extend through to the top of the receiving frame and are respectively connected to the first gear and the second gear.

[0015] Furthermore, a pair of receiving grooves are provided on the upper and lower sides of the centrifugal rod, and multiple slots are provided on the inner wall of the receiving grooves. An elastic lever is inserted into the inside of the slot, and the end of the elastic lever is fixedly connected to the inner wall of the groove.

[0016] This invention provides a centrifugal molding device for concrete cement poles. It has the following beneficial effects: 1. This centrifugal molding device for concrete cement poles uses a sensor matrix consisting of temperature, humidity, and pressure sensor subarrays and a hydration heat release monitoring probe to perform multi-dimensional, distributed real-time monitoring of the steam curing tank. This allows for precise capture of environmental deviations that traditional methods cannot identify, such as vertical temperature stratification, humidity dead zones, and insufficient steam driving force. It stabilizes environmental factors in different areas of the steam curing tank, reducing the overall variation in the steam curing quality of the cement poles. Furthermore, the control unit dynamically compares real-time environmental data vectors with standard environmental temperature curves constructed based on a vast number of successful cases. By synthesizing a ventilation coefficient using normalized deviation and sensitivity weights, it transforms vague human experience judgments into precise quantitative calculations. This ensures that the steam curing process of each batch of cement poles strictly adheres to the ideal "static stop, heating up, constant temperature, cooling down" process curve, significantly improving the consistency and pass rate of product strength.

[0017] 2. This centrifugal molding device for concrete cement poles automatically determines the actual power of the execution unit based on the ventilation coefficient through a power mapping model. When the environment conforms to the standard, it maintains the micro-flow of steam with only the minimum circulation power, avoiding ineffective high-power operation. When the environment deviates, it adjusts proportionally as needed. When there is a serious deviation, it corrects the deviation at full power and alarms. This on-demand air supply and dynamic closed-loop adjustment method solves the energy waste problem caused by blindly extending the steam curing time and excessive steam supply in traditional steam curing to ensure minimum strength. It realizes the refined and energy-saving operation of the steam curing process and shortens the mold turnover cycle. Attached Figure Description

A pair of slide rails 6 are fixedly connected to both ends of the feeding bracket 1, a slider 61 is slidably connected inside the slide rails 6, a threaded hole is opened on the side of the slider 61, a lead screw 62 is engaged and inserted into the threaded hole, and a control motor with its output end fixedly connected to the end of the lead screw 62 is provided at the end of the slide rail 6. A first linkage frame 63 is fixedly connected to the top of block 61. A first hydraulic cylinder 64 is installed at the end of the first linkage frame 63. A second linkage frame 65 is fixedly connected to the output end of the first hydraulic cylinder 64. A shaping template 66 is fixedly connected to the end of the second linkage frame 65 near the semi-steel mold 2. An arc-shaped notch 67 is opened at the top of the shaping template 66. A feeding cylinder 7 is inserted into the arc-shaped notch 67. A tripod 71 is fixedly connected to the bottom of the feeding cylinder 7. A feeding component is provided at the top of the feeding cylinder 7. The position of the reinforcing bar 4 is staggered from that of the feeding cylinder 7 to avoid obstructing the movement of the feeding cylinder 7. When centrifugally molding cement poles, concrete needs to be filled into the semi-steel mold 2 first. The existing filling method involves placing side panels on both sides of the semi-steel mold 2 during filling, and then pouring the concrete between the panels. Concrete continuously enters the semi-steel mold 2 during this process. However, in actual operation, the spiral steel wire 5 inside the semi-steel mold 2 hinders the concrete's entry. To ensure sufficient filling within the semi-steel mold 2, workers need to manually push the concrete while maintaining an arc shape so that it is fully filled after mold closing. Based on this, a shaping template 66 is designed. A pair of shaping templates 66 are designed in an arc shape, which, when joined, forms a perfect circle with the arc-shaped notch of the semi-steel mold 2. The structure conforms to the filling shape of the concrete after the mold is closed. The specific operation is as follows: the feeding component first controls the material feeding cylinder 7 to move downward and insert into the interior of the semi-steel mold 2. When it encounters the spiral steel wire 5, the tip of the tripod 71 at the bottom of the material feeding cylinder 7 will push it away to avoid obstructing the movement of the material feeding cylinder 7. Then, the concrete is injected into the material feeding cylinder 7. As the concrete is injected, the material feeding cylinder 7 is controlled to move upward gradually, so that the concrete gradually fills the interior of the semi-steel mold 2 from bottom to top. That is, the concrete is injected from inside the spiral steel wire 5 and gradually piled up to fill. When the bottom of the material feeding cylinder 7 moves to the position of the arc-shaped notch 67, it stops. At this time, the area of ​​the semi-steel mold 2 covered by a pair of fixed templates 66 is filled. Then, the control motor controls the lead screw 62 to rotate, and the lead screw 62 engages with the threaded hole of the slider 61 for transmission. The slider 61 drives the first linkage frame 63, the first hydraulic cylinder 64, and the second linkage frame 65 to move. The second linkage frame 65 drives the shaping template 66 and the feeding cylinder 7 to move synchronously. The area of ​​the semi-steel mold 2 after filling remains arc-shaped, and no manual shaping is required by the worker. The shaping template 66 moves to the unfilled area and stops, and then the filling is repeated. Throughout the process, the concrete is fully filled into the semi-steel mold 2, and no manual shaping is required after filling, which improves the filling efficiency. When the filling is completed, the first hydraulic cylinder 64 drives the feeding cylinder 7 and the feeding component away from the semi-steel mold 2 to avoid interfering with the subsequent mold closing process. After the mold is closed, it is transferred to the centrifugal equipment, and the support shaft group of the centrifugal equipment drives the steel mold to rotate to achieve centrifugal molding. Finally, it is hoisted into the steam curing tank for steam curing. The feeding assembly includes a receiving cylinder 9, with the top of the receiving cylinder 9 fixedly connected to a connecting frame 91 fixedly connected to the inner wall of the receiving cylinder 9. The bottom end of the connecting frame 91 is located inside the feeding cylinder 7. A receiving plate 92 is fixedly connected to the bottom end of the connecting frame 91. A groove 93 is provided on the side of the receiving plate 92. A centrifugal rod 94 is inserted into the groove 93. A buffer spring 95 is fixedly connected to one end of the centrifugal rod 94 and the inner wall of the groove 93. A scraper 96 is fixedly connected to the other end of the centrifugal rod 94. The top of the feeding cylinder 7 is rotatably connected to the receiving frame 81. The top of the second linkage frame 65 is fixedly connected to the second hydraulic cylinder 8. The output end of the second hydraulic cylinder 8 is fixedly connected to the receiving frame 81. The top of the feeding cylinder 7 is fixedly connected to the first toothed ring 831. The side of the first toothed ring 831 is meshed with the first gear 83. The top of the first toothed ring 831 is slidably connected to the second toothed ring 821. The second toothed ring 821 is fixedly connected to the surface of the receiving cylinder 9. The side of the second toothed ring 821 is meshed with the second gear 82. A pair of drive motors are installed at the bottom of the receiving frame 81. The output ends of the pair of drive motors pass through to the top of the receiving frame 81 and are respectively connected to the first gear 83 and the second gear 82. When concrete is filled into the steel mold 2 through the discharge cylinder 7, an external concrete feeder continuously pours concrete into the hopper at the top of the receiving cylinder 9. The concrete then enters the discharge cylinder 7. During this process, a pair of drive motors drive the first gear 83 and the second gear 82 to rotate in opposite directions, causing the first gear ring 831 and the second gear ring 821 to rotate in opposite directions, thus achieving the opposite rotation of the discharge cylinder 7 and the receiving cylinder 9. Figure 12As shown, the inner wall of the discharge cylinder 7 is designed with a gradually decreasing thickness from top to bottom. Therefore, the concrete adhering to the inner wall of the discharge cylinder 7 generates a downward centrifugal force as the discharge cylinder 7 rotates, thus accelerating its detachment and facilitating the discharge process of the discharge cylinder 7. Meanwhile, as the receiving cylinder 9 rotates, its internal connecting frame 91 drives the receiving plate 92 to rotate synchronously. The receiving plate 92 drives the scraper 96 to rotate synchronously. Under the action of centrifugal force, the scraper 96 pulls the buffer spring 95 through the centrifugal rod 94, stopping when the scraper 96 contacts the inner wall of the discharge cylinder 7. The scraper 96 is designed... The scraper is positioned at an angle to fit the inner wall of the discharge cylinder 7, creating relative sliding when in contact with the inner wall. This scrapes and gathers the concrete adhering to the inner wall of the discharge cylinder 7, facilitating concrete detachment. Furthermore, during use, the rotation speed of the scraper 96 is controlled, causing the centrifugal force of the scraper 96 to fluctuate. When the centrifugal force of the scraper 96 decreases, the buffer spring 95 pulls the centrifugal rod 94 to return to its original position. When the centrifugal force of the scraper 96 increases, the scraper 96 pulls the centrifugal rod 94 away from the receiving plate 92, thus the centrifugal rod 94 will move towards... The centrifugal rod 94 reciprocates, and a pair of receiving grooves 941 are provided on the upper and lower sides. Multiple slots 942 are provided on the inner wall of the receiving grooves 941. Elastic levers 943 are inserted into the slots 942, and the ends of the elastic levers 943 are fixedly connected to the inner wall of the grooves 93. Therefore, as the centrifugal rod 94 reciprocates, the ends of the elastic levers 943 pass through different slots 942. During this process, the elastic levers 943 continuously bend to store energy and release it instantaneously. Specifically, the bending energy storage process is completed during the compression of the slots 942, and the energy storage... The release occurs when the concrete enters from one slot 942 to another. This process causes the slot 942 to vibrate, which in turn causes the overall structure connected to or indirectly connected to the receiving plate 92 to vibrate. This vibration facilitates the detachment of concrete from the structural surface, reduces the amount of concrete adhering to the surface, and is beneficial for the cleaning process. It should be noted that cleaning of structures related to the concrete conveying process is necessary. In practice, regular cleaning is essential; for example, the inner cavity of a concrete feeder needs to be cleaned regularly.
