[0026] A pull rod life detection device includes a detection control module 7 for data acquisition and data analysis, a hydraulic drive module 8 for power output, and a tensile detection module 10 for detecting the life of the pull rod.

[0027] The detection control module 7 includes a controller 71 and a display 72 connected to each other.

[0028] The hydraulic drive module 8 includes a connected hydraulic pump and a driver 81.

[0029] The stretch detection module includes a fixed base 1, a distance sensor 2 fixedly connected to the fixed base 1, an ultra-high pressure oil cylinder 4 and a support rod 5.

[0030] A central hole for installing the pull rod 3 is provided at the center of the support rod 5. The lower part of the ultra-high pressure oil cylinder 4 is connected to the hydraulic pump through a driver. The distance sensor 2 is electrically connected to the controller 71.

[0031] The hydraulic pump is used to provide power to the ultra-high pressure cylinder 4.

[0032] The distance measuring sensor 2 collects detection data in real time and transmits it to the controller 71 for data analysis.

[0033] The display 72 is used to display the detection pressure and the detection speed.

[0034] One end of the support rod 5 is connected to the ultra-high pressure cylinder 4, and the other end is connected to the bolt 6 of the tested pull rod 3. A center hole for installing the pull rod 3 is provided at the center of the support rod 5. The pull rod 3 passes through the center holes of the ultra-high pressure cylinder 4 and the support rod 5 and is fixedly connected to the fixed base 1. The pull rod life detection device mainly fixes the bolt 6 on the pull rod 3 in a spiral manner, and then provides hydraulic power to the ultra-high pressure cylinder 4 through the detection control module 7. The ultra-high pressure cylinder 4 opens and tightens the bolt 6, and then collects the detection data in real time through the distance measuring sensor 2, and transmits it to the controller 71 for data analysis. The analysis results are used to judge whether the quality of the pull rod 3 meets the requirements.

[0035] The display 72 displays the stretching speed, stretching pressure and stretching time in real time.

[0036] The tie rod life detection device in this embodiment first fixes the tie rod 3 to be detected on the fixed base 1 through the center hole of the ultra-high pressure oil cylinder 4 and the support rod 5. The tie rod life detection device mainly fixes the bolt 6 on the tie rod 3 in a spiral manner. At this time, the parameters such as the speed, pressure and time required for stretching are set on the display 72. The hydraulic drive module 8 drives the ultra-high pressure oil cylinder 4 to drive the tie rod 3 and the bolt 6 to perform the stretching operation. The distance sensor 2 collects the detection data in real time and transmits it to the controller 71 for data analysis. The analysis result is used to judge whether the quality of the tie rod 3 meets the requirements.

[0037] The controller 71 is provided with stretching speed, stretching pressure and stretching time settings. The stretching initialization is used to set the stretching speed, stretching pressure and stretching time. During the test, the stretching speed, stretching pressure and stretching time are displayed in real time on the display 72.

[0038] Controller 71 adopts self-developed controller, which has the functions of setting the stretcher model and speed, etc., which is convenient for operation and ensures the accuracy of stretching operation. The working pressure can also be adjusted through the PLC controller.

[0039] The hydraulic pump is a low-pressure pump, and the hydraulic drive module 8 also includes a booster 82 for boosting the pressure of the low-pressure pump. The low-pressure pump is used to supply oil, and the pressure is boosted to the required working pressure through the booster 82. The low-pressure pump is driven by a servo motor. When the pressure reaches the target pressure, the motor speed is reduced to achieve precise control of the pressure accuracy.

[0041] The tie rod life detection device also includes a radiator 9, which can diffuse the heat generated during the operation of the tie rod life detection device, keep the working temperature of the tie rod 3 stable and balanced during the stretching process, and ensure the accuracy and stability of the stretching process data.

[0042] In summary, the pull rod life detection device provided by the utility model first fixes the pull rod 3 to be detected on the fixed base 1 through the center holes of the ultra-high pressure oil cylinder 4 and the support rod 5. The pull rod life detection device mainly fixes the bolt 6 on the pull rod 3 in a spiral manner. At this time, the parameters such as the speed, pressure and time required for stretching are set on the display 72. The hydraulic drive module 8 drives the ultra-high pressure oil cylinder 4 to drive the pull rod 3 and the bolt 6 to perform the stretching operation. The distance sensor 2 collects the detection data in real time and transmits it to the controller 71 for data analysis. The analysis result is used to judge whether the quality of the pull rod 3 meets the requirements. The stretching pressure, time and speed can be used to detect whether the tie rod 3 has gaps, looseness, faults, deformation, etc., so as to judge whether the tie rod 3 meets the design standards. At the same time, the required load and stretching times can be checked and observed for a certain period of time to see whether the tie rod 3 has any breakage or damage. If the above phenomena occur in the test, it means that the quality of the tie rod 3 does not meet the requirements and needs to be improved. The data provided by multiple stretching tests can also be used to help evaluate the quality of the tie rod 3, provide a basis for the design and application of the tie rod 3, and thus control the quality of the tie rod. If the test results are slightly different, it means that the production process is stable and the quality of the tie rod 3 is consistent.

[0043] Those skilled in the art should understand that the above embodiments are only for the purpose of clearly illustrating the present invention, and are not intended to limit the scope of the present invention. For those skilled in the art, other changes or modifications may be made based on the above utility model, and these changes or modifications are still within the scope of the present utility model.
