[0025] like Figure 1As shown in the figure, this application provides a testing device for calibrating the output coefficient of a hydraulic steel sleeper. This testing device is used to test the output coefficient and stability of the steel sleeper 1. Specifically, the inspection device includes an inspection platform body 2, a force output mechanism 3, a reaction mechanism 4, and a pressure measurement system. The inspection platform body 2 includes a base 21 and a support frame 22, which are spaced apart along the height of the inspection platform body 2. The force output mechanism 3 includes a jack 31, an oil pump 32, and an oil pipe 33. The jack 31 is directly or indirectly mounted on the base 21, and the oil pipe 33 connects the oil pump 32 and the jack 31. The reaction mechanism 4 is arranged opposite to the force output mechanism 3 and is at least partially located on the upper side of the support frame 22. The reaction mechanism 4 includes a force transmission column 41 and a reaction plate 42. The reaction plate 42 is located on the side of the force transmission column 41 away from the jack 31 and abuts against the fixed surface 5 and can bear the pressure of the jack 31. The pressure measurement system is used to monitor the pressure values ​​of the jack 31 and the steel sleeper 1 and display the monitoring data.

[0026] In this embodiment, the inspection platform body 2 is used to support and fix the steel sleeper 1 to be tested. The output mechanism 3 is set on the inspection platform body 2 to apply pressure to the steel sleeper 1. The reaction mechanism 4 is also set on the inspection platform body 2 and is opposite to the output mechanism 3. It is used to withstand the pressure applied by the output mechanism 3 and maintain stability. The pressure measurement system is mainly used to measure and record the pressure values ​​on the steel sleeper 1 and the output mechanism 3 in real time. The inspection device provided in this embodiment has the advantages of simple structure, convenient operation, high detection efficiency, and accurate calibration of the output coefficient and stability of hydraulic steel sleepers. It can provide reliable technical support for the inspection of steel sleepers in hydropower projects.

[0027] like Figure 1 As shown, in one specific embodiment, the inspection device further includes a protective component 7, which includes a first pad 71 and a second pad 72. The first pad 71 and the second pad 72 are made of mortar and fine wire mesh. After curing, when the steel sleeper 1 is inspected, the first pad 71 and the second pad 72 are respectively placed on the upper and lower sides of the steel sleeper 1 and used to protect the surface of the steel sleeper 1, thereby preventing the steel sleeper 1 from being damaged by force.

[0028] like Figure 1As shown, in one specific embodiment, the output mechanism 3 further includes a first slider 34 and a second slider 35. The first slider 34 is disposed between the base 21 and the jack 31, and the second slider 35 is disposed between the jack 31 and the second pad 72. Furthermore, the reaction mechanism 4 includes a first pad 43 and a second pad 44, which are sequentially disposed on top of the first pad 71, and the first pad 43 can pass through the support frame 22. In this embodiment, the first slider 34 and the second slider 35 are respectively disposed at the top and bottom of the jack 31 to transmit the pressure applied by the jack 31. The arrangement of the first slider 34 and the second slider 35 ensures that the pressure applied by the jack 31 can be evenly transmitted to the steel sleeper 1, avoiding the problem of inaccurate detection results due to excessive local pressure.

[0029] like Figure 1 As shown, in one specific embodiment, the number of jacks 31 is at least two, and at least two jacks 31 are spaced apart on the top of the first slider 34. The number of force transmission columns 41 is the same as the number of jacks 31, and the force transmission columns 41 are arranged in a one-to-one correspondence with the jacks 31. The reaction plate 42 includes a first reaction plate 45 and at least two second reaction plates 46. The second reaction plates 46 are correspondingly arranged on the top of the force transmission columns 41, and the first reaction plate 45 is arranged between the second reaction plates 46 and the fixed surface 5. The arrangement of the force transmission columns 41 can ensure that the pressure applied by the jacks 31 can be transmitted to the rock mass or the fixed surface 5, and then evenly transmitted to the steel sleeper 1 in the opposite direction through the reaction plates 42 and the two pads, ensuring that the upper and lower sides of the steel sleeper 1 bear uniform pressure.

[0030] like Figure 1 As shown, in one specific embodiment, the pressure measurement system includes a first pressure sensor 61, a second pressure sensor 62, a data acquisition unit, and a display. The first pressure sensor 61 is disposed on the oil pipe 33, and the second pressure sensor 62 is disposed on the steel sleeper 1. The data acquisition unit is connected to the first pressure sensor 61, the second pressure sensor 62, and the display. Specifically, the data acquisition unit is connected to both the first pressure sensor 61 and the second pressure sensor 62 and is used to receive and process the signals from the two pressure sensors. The display is connected to the data acquisition unit and is used to display the pressure values ​​and plot the pressure relationship curve. Through the data acquisition unit and the display, the pressure values ​​on the steel sleeper 1 and the jack 31 can be obtained in real time and accurately, and the relationship curve between the two can be plotted, thereby facilitating data analysis and processing.

[0031] like Figure 1As shown, when using the testing device in this embodiment to test the output coefficient and stability of a hydraulic steel sleeper, the steel sleeper 1 to be tested is first placed on the main body 2 of the testing table. Then, the first and second pads 71 ​​and 72, which have been cast and cured, are placed on the upper and lower sides of the steel sleeper 1. The position of the jack is adjusted, and the pressure sensor, pads (first pad 43 and second pad 44), reaction plate 42, and force transmission column 41 are installed. Next, pressure is applied to the jack 31 step by step by the oil pump 32, and the steel sleeper 1 is passively compressed. During the pressure application process, the data acquisition unit receives and processes the signals from the pressure sensor in real time, and transmits the pressure values ​​on the steel sleeper 1 and the jack 31 to the display for display. At the same time, the display will also draw a pressure relationship curve based on the recorded pressure values ​​for subsequent data analysis and processing.

[0032] To more accurately calibrate the output coefficient and stability of the hydraulic steel sleeper 1, the testing device of this embodiment can perform multiple repeated tests and record the data from each test. By statistically analyzing the data from multiple tests, more reliable output coefficient and stability indicators of the hydraulic steel sleeper can be obtained. Furthermore, the testing device of this embodiment can be improved and optimized according to actual needs. For example, more pressure sensors can be added to improve the accuracy and precision of the measurement; different sized blocks can be cast for testing steel sleepers of different sizes, etc.

[0033] In summary, the inspection device provided in this application has the following advantages: Simple structure and convenient operation: Through modular design, various components are integrated to form a complete inspection device. During use, only assembly and debugging according to the operating steps are required, eliminating the need for a complex installation process. High inspection efficiency: Employing a pressure measurement system and data acquisition unit, the pressure values ​​on the steel sleeper 1 and jack 31 can be obtained in real time and accurately, and pressure relationship curves can be plotted. Through data analysis, the output coefficient and stability index of the hydraulic steel sleeper 1 can be quickly obtained, improving inspection efficiency. High accuracy: The design of the reaction mechanism 4 further improves the accuracy and stability of the inspection. Wide applicability: Suitable for the inspection needs of hydraulic steel sleepers of different sizes and models. By replacing pads of different sizes, it can adapt to the inspection of steel sleepers of different specifications.

It can accurately calibrate the output coefficient and stability of hydraulic steel sleepers.
