Description

Technical Field

[0001] This utility model relates to the field of concrete component testing devices, and in particular to a performance testing device for precast concrete components. Background Technology

[0002] In the field of engineering testing, static load tests are typically conducted on precast concrete components to assess their load-bearing capacity, deformation characteristics, and durability. These tests usually employ multi-point loading, applying a uniformly distributed load to simulate the actual stress state and monitoring load and displacement changes in real time to ensure the test results meet specifications. Currently, this technology is widely used in the quality inspection of bridges, buildings, and other engineering projects, and its loading accuracy and stability directly affect the assessment of structural safety.

[0003] However, existing static load tests on precast concrete components still have significant drawbacks. First, traditional static load tests often use mechanical jacks as loading units, whose loading forces are easily affected by factors such as ambient temperature and manual operation, leading to uneven loading speeds and failing to meet the specifications for uniform loading and stable load holding. Second, near the load holding stage, staff need to repeatedly adjust the loads of each loading unit, which is not only time-consuming and labor-intensive, but also difficult to achieve precise synchronization between loading units, easily causing uneven load distribution and affecting the reliability and accuracy of test data. Furthermore, existing technologies lack integrated control; each loading unit operates independently, making data acquisition and adjustment processes cumbersome and increasing the complexity of the test and labor costs. Utility Model Content

[0004] The main purpose of this invention is to overcome the shortcomings of the existing technology and provide a performance testing device for precast concrete components that has uniform loading speed, stable load holding, simplifies the operation steps of adjusting the loading unit, ensures the reliability and accuracy of test data, and reduces the complexity of the test and labor costs.

[0005] To achieve the above objectives, this utility model provides a performance testing device for precast concrete components, including a control console, a liquid supply mechanism, several testing mechanisms, and hydraulic jacks. The liquid supply mechanism and the testing mechanisms are respectively communicatively connected to the control console. The liquid supply mechanism is used to supply oil to the several hydraulic jacks. Each of the several hydraulic jacks is equipped with a testing mechanism, which is used to monitor the load and displacement of the component and transmit data to the control console.

[0023] Example 1: This utility model proposes a device for testing the performance of precast concrete components.

[0024] In one embodiment of this utility model, a performance testing device for precast concrete components includes a control console 1, a liquid supply mechanism 2, several testing mechanisms 3, and hydraulic jacks 4. The liquid supply mechanism 2 and the testing mechanisms 3 are respectively connected to the control console 1. The liquid supply mechanism 2 is used to supply oil to the several hydraulic jacks 4. Each of the several hydraulic jacks 4 is equipped with a testing mechanism 3. The testing mechanism 3 is used to monitor the load and displacement of the component and transmit data to the control console 1.

[0025] Specifically, such as Figures 1 to 3As shown, in this utility model's performance testing device for precast concrete components, since the liquid supply mechanism 2 and the testing mechanism 3 are respectively connected to the control console 1, the operator can start, stop, or adjust the liquid supply mechanism 2 and receive monitoring data transmitted from the testing mechanism 3 through the control console 1. The structural design is simple and reasonable. Furthermore, in actual use, after the operator fixes the precast concrete component in the preset position, they can operate the control console 1 to make the liquid supply mechanism 2 supply oil to several hydraulic jacks 4, thereby driving the power output end (piston) of the hydraulic jacks 4 to lift the precast concrete component and apply a load to it. This simulates the actual stress state of the precast concrete component and completes the static load test. The operation is simple and convenient. Obviously, the performance testing device for precast concrete components of this utility model uses a hydraulic jack 4 to replace the traditional mechanical jack. Through the liquid supply mechanism 2, the hydraulic fluid can be stably delivered. Combined with the closed-loop control function of the control console 1, the loading process is not affected by the ambient temperature. This ensures a uniform loading speed, meets the uniform loading requirements of the specifications, and ensures stable pressure during the holding phase, making it reliable in use.

[0026] Understandably, in the process of using the concrete precast component performance testing device of this utility model, since each of the hydraulic jacks 4 is equipped with a testing mechanism 3, the testing mechanism 3 can be a weight detection module or displacement monitoring module commonly used in the prior art. When approaching the holding stage, the testing mechanism 3 can collect the load and displacement data of the concrete precast component from the power output end of the hydraulic jack 4 in real time and feed it back to the control console 1. The control console 1 automatically adjusts the hydraulic pressure output of each hydraulic jack 4, thereby achieving precise control of each hydraulic jack 4. This not only eliminates the need for staff to repeatedly adjust each hydraulic jack 4, reducing the complexity of the test and the manpower and time costs, but also ensures the uniformity of load distribution and guarantees the reliability and accuracy of the test data.

[0027] It should be noted that the control console 1 is equipped with a corresponding data processing module. This module can be a mature and conventional industrial control computer (PLC) or embedded microprocessor system, which has a built-in data acquisition card, PID control algorithm module, and human-machine interface. It can receive load and displacement signals transmitted by the detection mechanism 3 in real time, perform data comparison and analysis through a preset program, and output control commands to the relevant hydraulic control components of the fluid supply mechanism 2, thereby realizing closed-loop regulation of the hydraulic pressure of each hydraulic jack 4. This module also has common functions in existing technologies such as data storage, over-limit alarm, and curve generation, thus meeting the standardized requirements of engineering testing. In addition, since the preset program and related control principles of this data processing module are mature existing technologies, they will not be described in detail here.

[0028] In one embodiment, the liquid supply mechanism 2 includes an oil tank 5, an oil pump, and a multi-way valve assembly 6. The multi-way valve assembly 6 is connected to the oil pump and several hydraulic jacks 4 via oil pipes. Specifically, as shown... Figure 1 and Figure 3 As shown, the oil tank 5 provides a stable oil reserve for the entire hydraulic system, ensuring sufficient oil volume during long-term testing; the oil pump, as a power source, can pressurize and deliver the oil, providing a more stable pressure output compared to traditional mechanical loading methods; the multi-way valve group 6 connects the oil pump and each hydraulic jack 4 through oil pipes, realizing intelligent distribution of the hydraulic circuit, which not only ensures pressure balance at each loading point, but also allows the oil intake of each hydraulic jack 4 to be independently adjusted via the control panel 1, thereby precisely controlling the force applied at each loading point.

[0029] In one embodiment, a load plate 7 is provided at the piston end of several hydraulic jacks 4, and the detection mechanism 3 includes a weighing sensor 8, which is embedded in the top surface of the load plate 7 and communicatively connected to the control console 1. Specifically, as shown... Figure 1 and Figure 3 As shown, the load plate 7 increases the contact area between the output end of the hydraulic jack 4 and the precast concrete component, allowing the output force of the hydraulic jack 4 to be evenly transmitted to the bottom surface of the precast concrete component, effectively preventing localized stress concentration. Furthermore, by directly embedding the weighing sensor 8 on the top surface of the load plate 7, the actual load value acting on the specimen can be measured in real time and accurately, thus ensuring the accuracy of the test results.

[0030] In one embodiment, the detection mechanism 3 includes a displacement sensor 9, which is disposed on the side wall of the hydraulic jack 4 cylinder and is communicatively connected to the control console 1. Specifically, as shown... Figure 1 and Figure 3 As shown, by directly fixing the displacement sensor 9 to the cylinder side wall of the hydraulic jack 4, a relatively stable displacement measurement reference point can be established, thereby monitoring the precise extension of the piston rod in real time, and thus accurately detecting the actual deformation of the precast concrete component, making it reliable in use.

[0031] In one embodiment, the control console 1 includes a cabinet 10, a control system, a display screen 11, a panel 12, and a baffle 13. The control system is housed within the cabinet 10. The display screen 11 and panel 12 are both located on the top of the cabinet 10 and are communicatively connected to the control system. The baffle 13 is hinged to the cabinet 10 and serves to shield the display screen 11 and panel 12. Specifically, as... Figure 1 and Figure 2As shown, the cabinet 10 provides a stable installation space for the control system, thus preventing environmental interference to the electronic components of the control system. Meanwhile, the display screen 11 and panel 12 on the top of the cabinet 10 allow operators to intuitively monitor test data and conveniently operate the control system, making it simple and easy to use. Furthermore, since a baffle 13 is hinged to the cabinet 10, it can shield the display screen 11 and panel 12 when no static load test is being performed, thus preventing dust contamination and accidental operation, improving the equipment's protection and service life.

[0032] In one embodiment, a groove 14 is provided on the side wall of the cabinet 10. The groove 14 contains several interfaces 15 for communication between several detection mechanisms 3 and the control system. A cover plate 16 for sealing the inner cavity of the groove 14 is detachably installed at the opening of the groove 14. Specifically, as shown... Figure 1 and Figure 2 As shown, by setting several interfaces 15 in the groove 14, multiple signal lines can be arranged and connected in an orderly manner. At the same time, since a cover plate 16 is detachably installed at the groove opening of the groove 14, the detachable cover plate 16 not only ensures the convenience of operation when connecting the interfaces 15, but also effectively prevents dust and moisture from the interfaces 15 when not connected. This not only avoids signal interference or damage to the interfaces 15 caused by exposed lines in complex field environments, but also significantly improves the reliability and stability of line connections. At the same time, it makes the equipment look neat and beautiful, and facilitates on-site maintenance and management.

[0033] In one embodiment, a moving mechanism 17 is also included. The control console 1 and the liquid supply mechanism 2 are both mounted on the moving mechanism 17. The moving mechanism 17 includes a base plate 18 and a plurality of rollers 19 arranged in a rectangular array on the bottom surface of the base plate 18. A handle 20 is provided on the side wall of the control console 1. Specifically, as... Figure 1 As shown, the base plate 18 provides a stable mounting platform for the control console 1 and the liquid supply mechanism 2. The numerous rollers 19 arranged in a rectangular array on the bottom surface of the base plate 18 provide stable multi-point support for the base plate 18 and other mechanisms, ensuring the operational stability and reliability of this invention. This also allows for flexible arrangement at the testing site, improving transport convenience. Furthermore, the handle 20 on the side wall of the control console 1 facilitates easy operation for staff, including pushing and turning the device.

[0034] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
