[0027] An adjustable detection device also includes an adjustment control system, the adjustment control system includes a detection module and a processing module, the detection module includes a time recognition submodule, a vibration receiving submodule and an offset submodule, the offset submodule is electrically connected to the displacement sensor 22, and the vibration receiving submodule is electrically connected to the vibration sensor; The processing module includes a telescopic control submodule, an oil injection submodule, an alarm submodule and an air injection submodule, the telescopic control submodule is electrically connected to the third cylinder 16, the oil injection submodule is electrically connected to the oil pump 19, and the air injection submodule is electrically connected to the air pump 24; The regulation control system includes the following specific operation steps: Step 1: When the mobile vehicle 1 is moving, the vibration sensor detects in real time whether the mobile vehicle 1 is vibrating while walking, and transmits the signal to the vibration receiving submodule for recording; Specifically, the frequency threshold of the vibration of the mobile vehicle 1 is set to a low level and a high level in the vibration receiving submodule, and the vibration value detected in real time is transmitted to the vibration receiving submodule to determine the vibration degree of the mobile vehicle 1.

[0028] Step 2: When the mobile vehicle 1 moves, the first cylinder 8 and the second cylinder 7 are controlled to work, so that the detection probe 9 is lifted to the position to be detected, and the working state of the connecting arm 2 4 is determined during the lifting process; Step 3: The vibration frequency generated when the mobile vehicle 1 moves and the working condition of the connecting arm 2 4 are used to further determine the working condition of the detection device.

[0029] Specifically, since the mobile vehicle 1 is always moving, there will be bumps on the road. When the vibration level changes from low to high, the shaking level of the connecting arm 2 4 is further judged. When the vibration level changes from low to high, the connection between the connecting arm 2 4 and the connecting plate 1 5 and the connecting plate 2 6 is loose. At this time, the signal is transmitted to the alarm submodule to suspend the detection device.

[0030] Through the above steps, when the mobile vehicle 1 moves, the change of the working state of the connecting arm 2 4 is determined in real time according to the road conditions, so as to prevent the shaking of the connecting arm 2 4 from causing the shaking of the detection probe 9 to affect the detection and measurement accuracy.

[0031] Step 2 includes the following steps: Step 2-a: When the first cylinder 8 is working, it pushes the second connecting arm 4 to swing upward. At this time, the shaking recognizes the time when the second connecting arm 4 reaches the set position through the time recognition submodule, and determines whether there are impurities at the rotating rod 11 that affect the operation of the second connecting arm 4; Specifically, the staff sets the time for the connecting arm 2 4 to reach the set position as t in the time recognition submodule. When the time to reach the set position is less than or equal to the set time t, it indicates that there is no impurity at the rotating rod 11. When the time to reach the set position is greater than the set time t, it indicates that there is a jamming phenomenon at the rotating rod 11 that affects the operation of the connecting arm 2 4. When there are impurities on the rotating rod 11, the air pump 24 is first started through the jet submodule to blow the external air to the surface of the rotating rod 11 through the nozzle 2 13 to blow away the surface impurities, so that the surface of the rotating rod 11 is clean, and then the oil pump 19 is controlled to start through the oil spray submodule to spray the lubricating oil in the oil chamber 17 through the nozzle 1 23 into the connection between the rotating rod 11 and the connecting plate 1 5 and the connecting plate 2 6, which can improve the lubrication of the connection between the rotating rod 11 and the connecting plate 1 5 and the connecting plate 2 6; Furthermore, when the lubricating oil is sprayed on the connection between the rotating rod 11 and the connecting plate 1 5 and the connecting plate 2 6, the air pump 24 is started again to continue to spray the gas onto the surface of the rotating rod 11, so that the lubricating oil sprayed on the connection between the connecting plate 1 5 and the connecting plate 2 6 can be blown away, thereby expanding the lubricating oil lubrication area for better lubrication; Step 2-b: When the connecting arm 2 4 swings upward, the displacement sensor 22 is used to determine whether the connecting arm 2 4 is shaking; Specifically, the staff sets the shaking level of the connecting arm 24 in the offset submodule, which are low and high respectively. Therefore, the displacement sensor 22 will detect the numerical value in real time and transmit it to the offset submodule for matching with the set level to identify the shaking degree of the connecting arm 24. When the shaking degree of the connecting arm 24 is low, the signal is transmitted to the telescopic submodule when the connecting arm 24 reaches the set position, and the third cylinder 16 is controlled to extend, so that the pressure plate 15 and the surface of the connecting plate 15 are pressed against each other, thereby increasing the stability of the connecting arm 24 and avoiding the shaking of the connecting arm 24, which affects the measurement accuracy. When the shaking degree of the connecting arm 24 is high, the signal is transmitted to the alarm submodule to inform the staff to come for maintenance.

[0032] Step 2-c: Combine the degree of impurities on the rotating rod 11 with the degree of shaking of the connecting arm 2 4 to judge the working accuracy of the detection device as a whole; Specifically, when there are impurities on the rotating rod 11 and the shaking degree of the connecting arm 2 4 is low, the shaking degree of the connecting arm 2 4 becomes high after the impurities on the rotating rod 11 are cleaned and lubricated, indicating that the impurities at the connection between the rotating rod 11 and the connecting plate 1 5 and the connecting plate 2 6 increase the stability of the connecting arm 2 4, and the shaking degree of the connecting arm 2 4 can be judged more accurately; Through the above steps, the working state of the connecting arm 2 4 can be judged when the connecting arm 2 4 is working, and appropriate adjustments can be made to further ensure the working accuracy of the detection device.

[0033] It should be supplemented that an adjustment component is still provided in the subsequent connecting arm three 20 and the connecting arm four 10, and the above-mentioned detection steps are used to detect the working status of the connecting arm three 20 and the connecting arm four 10.
