[0002] In the construction industry, cement quality is paramount, directly impacting the safety and stability of building projects. As a core component of building materials, cement not only determines the strength and durability of concrete but also plays a decisive role in the compressive strength, crack resistance, and impermeability of structural components. Substandard cement can lead to serious safety hazards such as cracks, structural loosening, and even collapse, posing a significant threat to people's lives and property. Furthermore, cement quality affects construction efficiency and subsequent maintenance costs; substandard cement can cause early-stage defects in building structures, increasing repair and reinforcement expenses.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] First embodiment: See Figures 1-2 As shown, this utility model provides a cement quality testing device, including a frame 1, on which multiple testing stations 2 are provided for performing cement quality testing operations simultaneously or separately. Each testing station 2 consists of a chassis 3 and an operation box 4 located below the chassis 3, forming a testing structure unit with corresponding upper and lower positions; The chassis 3 includes an outer shell, as well as a power unit, signal processing unit, control unit and heat dissipation unit integrated within the outer shell. The units work together to achieve detection, control and operation functions. The power unit specifically includes a telescopic device 5 installed on the top surface of the housing. The telescopic end of the telescopic device 5 passes through the bottom plate of the housing 3 and faces the inner bottom surface of the operating box 4, so as to act on the detection object inside the operating box 4. The signal processing unit is installed at the telescopic end of the telescopic device 5 and can adjust its position synchronously with the movement of the telescopic end, thereby accurately receiving and processing the detection signal; In addition, the power unit, signal processing unit and heat dissipation unit are all electrically connected to the control unit. Through the unified control of the control unit, the coordinated work of each component is realized, ensuring the stable operation of the detection process. In addition, the bottom of the frame 1 is equipped with casters and adjustable feet. These two components work together to facilitate the movement and fixation of the device.

[0020] Among them, the casters facilitate the flexible movement of the entire cement quality testing device by the frame 1, and the placement of the device can be adjusted according to the testing needs, thereby improving the flexibility of the device.

[0021] The adjustable feet can keep the frame 1 stable by adjusting its height after the device is moved to the target position, so as to avoid the device from shaking during the detection process and affecting the detection accuracy. At the same time, it enhances the stability of the device when it is placed and ensures that the detection work is carried out reliably.

[0022] The second embodiment differs from the first embodiment in that: The signal processing unit comprises a signal conditioning circuit, a data acquisition card, and a sensor interface module. These components work together to process and transmit the detected signals. The sensor interface module is connected to both the pressure sensor 6 and the displacement sensor 7, receiving the detected signals from these sensors and providing raw data input for subsequent signal processing.

[0023] The control unit includes a PLC, which serves as the control center of the entire detection device and is responsible for coordinating and regulating the operation of each component.

[0024] The heat dissipation unit specifically includes an air inlet, an air outlet, and a temperature-controlled fan assembly. It achieves heat dissipation through air circulation and fan drive, ensuring that the internal components of the device operate stably at a suitable temperature.

[0025] In addition, each testing station 2 is also equipped with a display module 8 and a control button 9. The control button 9 is used by the operator to input control commands, while the display module 8 is used to display information such as testing data and operating status, which facilitates real-time monitoring and operation.

[0026] Furthermore, the control button 9, display module 8, pressure sensor 6, displacement sensor 7, and temperature control fan assembly are all electrically connected to the PLC. The PLC enables centralized signal processing and unified command transmission, ensuring coordinated operation of all components and allowing the detection process to proceed in an orderly manner. The control unit also includes a power module and a data storage unit. The power module is mainly responsible for supplying power to the PLC itself and other components electrically connected to it, such as the power unit and the signal processing unit, to ensure that the electrical system of the entire detection device can operate continuously and reliably.

[0027] The data storage unit is used to store various types of data generated during the detection process, including detection data collected by pressure sensor 6 and displacement sensor 7 and processed by the signal processing unit, as well as information such as the device's operating parameters and operation records. This facilitates subsequent querying, analysis, and traceability of the detection results, enhancing the device's data management capabilities.

[0028] Inspection station 2 is also equipped with an alarm device 10, which consists of a buzzer and an alarm indicator light. The alarm function is achieved through dual prompts of sound and light signals.

[0029] Meanwhile, the alarm device 10 is electrically connected to the control unit. When an abnormal situation occurs during the detection process, such as the detection data exceeding the preset range or equipment malfunction, the control unit can trigger the alarm device 10, causing the buzzer to sound and the alarm indicator light to illuminate, thus promptly reminding the operator to handle the situation.

[0030] In addition, multiple sets of control buttons 9 and display modules 8 are provided, and each set of control buttons 9 and each set of display modules 8 are respectively associated with the corresponding detection station 2. This one-to-one correspondence setting allows operators to individually control the operation of the corresponding inspection station 2 through specific control buttons 9, and at the same time accurately view the real-time inspection data, operating status and other information of the inspection station through the corresponding display module 8, which improves the pertinence of operation and the convenience of viewing inspection information. The telescopic device 5 can be equipped with a hydraulic cylinder or a pneumatic cylinder. Both types of telescopic devices can provide stable telescopic power to meet the power output requirements in different scenarios. The telescopic end of the telescopic device 5 is connected to a pressure head mounting base 11, which serves as a connecting carrier and provides a fixed position for the installation of the sensor. Pressure sensor 6 and displacement sensor 7 are both mounted on pressure head mounting base 11, enabling these two sensors to move synchronously with the telescopic end of expansion joint 5. This allows them to accurately collect pressure and displacement data when the expansion joint approaches the object being tested, providing key parameters for cement quality testing.

[0031] The third embodiment differs from the first embodiment in that: The bottom plate 12 of the control box 4 is slidably set, the frame 1 is provided with a support plate 13, the support plate 13 is provided with a drawer 14, the control box 4 is provided with a stop bar 15, and the bottom plate 12 of the control box 4 is mainly used to support the concrete test block and serve as a carrier for placing the test block during the testing process. When the concrete test block that has been tested needs to be removed, during the process of pulling out the base plate 12, the stop bar 15 inside the operation box 4 will limit the concrete test block. Due to the obstruction of the stop bar, the concrete test block cannot slide outward with the base plate 12. As the base plate 12 continues to slide out, its support for the concrete test block gradually disappears. The test block remains in position under the limit of the stop bar, and eventually falls into the drawer 14 of the receiving plate 13 on the frame 1 after losing support, thus realizing the automatic collection of the concrete test block after testing and simplifying the sample processing procedure after testing. A partition 16 is provided between two adjacent testing stations 2. This partition can form a physical separation between adjacent stations, reduce mutual interference between different stations during the testing process, and ensure that each station operates independently.

[0032] A transparent sealing plate 17 is provided between two adjacent partition plates 16. Its transparency allows the operator to clearly observe the situation inside the corresponding testing station, while also providing protection to prevent debris, dust, etc. that may be generated during the testing process from spreading outward.

[0033] The sealing plate 17 and the partition plate 16 are connected by a sliding method, which makes it easy for operators to push the sealing plate 17 to slide as needed, flexibly open or close the protective space of the work station, and take into account both protection and ease of operation.

[0034] In addition, a magnetic block 18 is provided on the top of the sealing plate 17. The magnetic block can form a magnetic attraction with the frame 1. When the sealing plate 17 is in the closed state, the magnetic attraction can fix it in place and prevent the sealing plate from sliding open due to accidental touch, thus ensuring the protective effect. When it is necessary to open the sealing plate, only an appropriate external force needs to be applied to overcome the magnetic force and push the sealing plate 17 to slide, which is convenient to operate.

[0035] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
