Description

Technical Field

[0001] This utility model relates to the field of concrete scale calibration technology, and in particular to a scale calibration device for concrete production. Background Technology

[0002] In modern concrete production, the accuracy of batching directly affects the quality and performance of concrete. Therefore, extremely high requirements are placed on the weighing accuracy of raw materials. As concrete production moves towards automation and intelligence, weighing devices, as a key link in the production line, need to meet the requirements of continuous, efficient and accurate weighing. However, in actual production, equipment may cause weighing errors due to factors such as long-term use, environmental changes (such as temperature and vibration) or mechanical wear. This requires weighing devices to have convenient calibration functions.

[0003] Existing weighing devices used in concrete production typically lack a dedicated structure for hanging standard weights. Without a fixed location for weights, operators need to prepare additional tools or find temporary fixing points, increasing operational steps and potentially leading to calibration errors due to improper installation. Furthermore, the lack of a standardized hanging structure makes calibration time-consuming and labor-intensive, impacting production efficiency. This inconvenience is particularly pronounced in large-scale continuous production scenarios, increasing labor and time costs and potentially affecting the accuracy of concrete batching due to untimely or inaccurate calibration, thus negatively impacting concrete quality. Utility Model Content

[0004] In order to overcome the problem that existing weighing devices used in concrete production are complicated, time-consuming and labor-intensive when they need to be quickly calibrated to zero because they usually lack a structure for hanging standard weights, this utility model provides a calibration scale device for concrete production.

[0005] The technical solution is as follows: A weighing scale device for concrete production includes a weighing component, a weighing container component, and a lever switch component; the weighing component contains the weighing container component; the lever switch component is located at the lower end of the weighing container component; the weighing component includes a support frame and weighing sensors; the weighing container component includes a tank, a lifting ring, and a calibration hook; the lever switch component includes an opening and closing door, a scissor-type control lever, a lever frame, and a ladder frame; the support frame contains the tank; four weighing sensors are located between the upper edge structure of the tank and the support frame.

[0006] Furthermore, a switch door is provided at the lower end of the tank, and the shell of the switch door is sealed to the lower port of the tank.

[0007] Furthermore, scissor-type control levers are provided on both sides of the door, and the scissor-type control levers are rotatably connected to the outer wall of the door.

[0008] Furthermore, a lever frame is provided behind the scissor-type control lever, and the front and rear ends of the lever frame are rotatably connected to the scissor-type control lever and the support frame, respectively.

[0009] Furthermore, a ladder frame is provided at the rear end of the lever frame, and the ladder frame is integrally formed with the lever frame.

[0010] Furthermore, a calibration hook is provided at the rear end of the tank, and the calibration hook is rotatably connected to the tank.

[0011] Furthermore, a lifting ring is provided at the upper end of the tank, and the lifting ring is fixedly connected to the tank.

[0012] The beneficial effects are as follows: When the equipment of this utility model is running, the load cell undertakes the key weight measurement task, and monitors the weight changes of the tank and the concrete inside in real time. When it is necessary to open or close the door, the ladder plays a transmission role, and drives the lever frame by rotation, which in turn drives the scissor control rod to complete the precise control of the opening and closing of the door. The calibration hook and the ladder cooperate with each other to form an effective limit mechanism, ensuring that the door is in a normally closed and locked state, ensuring the safe and stable operation of the equipment. When the load cell needs to be calibrated, the operation is very simple. Just hang the standard weight on the calibration hook to calibrate the load cell to zero, so that the equipment can restore the accurate measurement performance.

[0013] By setting up a ladder frame, the rotation of the ladder frame is controlled by the lever principle, thereby realizing the opening and closing function of the scissor-type control lever. At the same time, the calibration hook can also serve as a hanging structure for standard weights, thus effectively improving the convenience of equipment maintenance. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] In today's era of rapid modernization, concrete, with its excellent plasticity, high strength, and economy, has become one of the most widely used engineering materials in many fields such as construction, transportation, and water conservancy. From towering skyscrapers to bridges spanning rivers, from crisscrossing highways to underground rail transit, concrete plays an irreplaceable and crucial role in various infrastructure constructions. Its quality and performance directly determine the service life and safety of engineering projects.

[0022] In modern concrete production, the batching process is undoubtedly the core element determining concrete quality. Concrete properties, such as strength, durability, and workability, are closely related to the proportions of raw materials. Different types of cement, coarse and fine aggregates, admixtures, and additives must be mixed in precise proportions to produce high-quality concrete that meets engineering requirements. For example, even a slight deviation in cement dosage can cause the final concrete strength to fall short of design requirements, reducing the load-bearing capacity of the building and creating safety hazards. Inaccurate aggregate proportions can affect the workability of the concrete, causing segregation and bleeding during construction, severely impacting construction quality and efficiency. Therefore, extremely high precision in weighing raw materials is required; any minute error can be amplified in subsequent engineering applications, leading to incalculable losses.

[0023] The concrete production industry is rapidly developing towards automation and intelligence. The introduction of automated production lines has significantly improved concrete production efficiency, reduced the uncertainties caused by manual intervention, and made the production process more stable and controllable. Intelligent systems, through big data analysis and machine learning technologies, can monitor various parameters in the production process in real time and automatically adjust the production process according to actual conditions, achieving precision and efficiency in concrete production. Under this development trend, the weighing device, as a key core component of the concrete production line, directly restricts the overall operational quality and product quality of the production line. It needs to meet the requirements of continuous, efficient, and accurate weighing to ensure that each batch of concrete meets design standards.

[0024] However, weighing devices face numerous challenges in actual production environments. Concrete production sites are often complex environments, with harsh conditions such as high temperature, high humidity, and dust being common. Prolonged use in such environments inevitably leads to corrosion and wear on the sensors, mechanical structures, and other components of the weighing device. For example, dust may enter the sensor, affecting its sensitivity and accuracy; high temperatures can cause zero-point drift and sensitivity changes in the sensor, resulting in measurement deviations; and the impact forces generated by mechanical vibrations during production can damage the sensor's elastomer, accelerating its aging process. All these factors contribute to weighing errors, causing deviations between the actual batching and the designed mix proportions.

[0025] More importantly, timely and accurate calibration is crucial when weighing devices malfunction. Calibration is essential to ensure the accuracy of weighing measurements. By comparing the measured values ​​of the weighing device with standard weights, the device parameters are adjusted to restore it to an accurate measurement state. However, existing weighing devices used in concrete production have significant structural design flaws. Typically, these devices lack a dedicated structure for hanging standard weights. Due to the absence of fixed and standardized weight placement locations, operators must prepare additional auxiliary tools, such as supports and ropes, or find temporary fixing points on the equipment to place the standard weights during calibration. This approach not only increases the number of calibration steps and reduces work efficiency but may also introduce new calibration errors due to improper installation of auxiliary tools or unstable temporary fixing points, leading to deviations in the placement and posture of the standard weights and compromising the accuracy and reliability of the calibration results.

[0026] Furthermore, the lack of standardized mounting structures makes the calibration process time-consuming and labor-intensive. In large-scale continuous production scenarios, weighing devices need frequent calibration to ensure the accuracy of concrete batching. Each calibration requires a significant amount of time and effort to prepare auxiliary tools, find suitable fixing points, and adjust the position of weights, which undoubtedly increases labor and time costs considerably. Moreover, due to the cumbersome and inconvenient calibration process, operators may reduce the frequency of calibration or perform it perfunctorily, resulting in untimely or inaccurate calibration. If the error of the weighing device is not corrected in time, the accuracy of concrete batching will be affected, which will have a serious adverse impact on the quality of concrete, and may even lead to engineering quality accidents, causing huge economic losses and social impacts.

[0027] In summary, the structural design flaws of existing weighing devices used in concrete production severely restrict the convenience and accuracy of their calibration, failing to meet the high precision and efficiency requirements of modern concrete production. Therefore, developing a weighing device for concrete production with a reasonable standard weight mounting structure and easy calibration is crucial for solving current quality control problems in concrete production. This has significant practical implications for promoting the intelligent development of the concrete production industry and improving the quality of engineering construction.

[0029] like Figures 1-5 As shown, a weighing device for concrete production includes a weighing component 1, a weighing container component 2, and a lever switch component 3. The weighing container component 2 is disposed inside the weighing component 1. The lever switch component 3 is disposed at the lower end of the weighing container component 2. The weighing component 1 includes a support frame 101 and a weighing sensor 102. The weighing container component 2 includes a tank body 201, a lifting ring 202, and a calibration hook 203.

[0035] During equipment operation, the load cell 102 undertakes the critical task of weight measurement, monitoring the weight changes of the tank 201 and its internal concrete in real time. When it is necessary to open or close the switch door 301, the ladder frame 304 plays a transmission role, driving the lever frame 303 through rotation, which in turn drives the scissor-type control rod 302 to achieve precise control of the opening and closing of the switch door 301. The calibration hook 203 and the ladder frame 304 cooperate to form an effective limit mechanism, ensuring that the switch door 301 is in a normally closed and locked state, ensuring the safe and stable operation of the equipment. When the load cell 102 needs to be calibrated, the operation is very simple. Just hang the standard weight on the calibration hook 203 to zero the load cell 102 and restore the equipment to accurate measurement performance.

[0038] With the ladder frame 304 in place, the rotation of the ladder frame 304 is controlled by the lever principle to rotate the lever frame 303, thereby realizing the opening and closing function control of the scissor-type control lever 302 on the door 301. At the same time, the calibration hook 203 can also be used as a hanging structure for standard weights, thus effectively improving the convenience of equipment maintenance.
