[0027] Firstly, the universal wheel 2 fixedly connected to the lower side of the device base 1 is used to realize the movement of the device. The operator pushes the device, and the device is easily moved to the position of the foundation pile to be detected by the rolling characteristics of the universal wheel 2. After reaching the detection position, the operator manually overturns the turnover plate 31 to make it at a suitable working angle. Then, the electric push rod 32 is started, and the electric push rod 32 starts to elongate to push the connecting plate 33 fixedly connected thereto to move downward. The ground cone 34 is installed below the connecting plate 33. With the downward movement of the connecting plate 33, the ground cone 34 gradually penetrates into the ground to realize the preliminary fixation of the device. To further enhance the stability of the device, the operator rotates the support rod 38 to unfold it from the initial storage state. After unfolding, the telescopic rod 39 is adjusted to move the anti-skid pad 312 connected to the end thereof downward until the anti-skid pad 312 is in close contact with the ground. Then, the fixing member 310 is screwed into the threaded hole 311 formed in the telescopic rod 39. The fastening force generated by the threaded connection fixes the telescopic rod 39 at the current position. At this time, the anti-skid pad 312 can effectively increase the friction between the device and the ground, thereby further improving the stability of the device. When the foundation pile detection is completed and the ground cone 34 needs to be retracted, the operator overturns the turnover plate 31 again to pull out the ground cone 34 from the ground. Then, the insertion rod 36 on the fixed plate 35 is inserted into the insertion hole 37 formed in the device base 1. Through the cooperation of the insertion rod 36 and the insertion hole 37, the turnover plate 31 and the device base 1 are fixed together to restore the state when the device moves. After the device is fixed, the detection of the foundation pile is started. First, the cylinder 4 installed on the device base 1 is started, and the telescopic end of the cylinder 4 starts to extend to push the clamping plate 5 fixedly connected thereto to move toward the foundation pile. With the movement of the clamping plate 5, it gradually approaches the foundation pile and applies a clamping force to the foundation pile to firmly fix the foundation pile, thereby ensuring the stability of the foundation pile position during the subsequent detection process and preventing the foundation pile from shaking or moving.
[0028] With reference to Figure 1 , Figure 4 and Figure 5 , the mounting assembly 10 comprises a pull rod 102 which is slidingly connected in the interior of the connecting block 8. An extrusion plate 106 is installed on the pull rod 102. A spring 101 is installed on the extrusion plate 106. The side of the spring 101 away from the extrusion plate 106 is fixedly connected to the connecting block 8. A clamping block 103 is fixedly connected to the inner side of the pull rod 102. A clamping groove 104 is formed in the pressure sensor 9. The clamping block 103 is slidingly connected in the interior of the clamping groove 104. A protection shell 105 is installed on the fixed frame 6. The pressure sensor 9 is slidingly connected in the interior of the protection shell 105.
[0029] When the foundation pile detection is completed, the ground cone 34 needs to be retrieved, the operator flips the turnover plate 31 again, and the ground cone 34 is pulled out of the ground. Then, the insertion rod 36 on the fixed plate 35 is inserted into the insertion hole 37 opened in the base 1. Through the cooperation of the insertion rod 36 and the insertion hole 37, the turnover plate 31 and the base 1 are fixed together, and the state when the device moves is restored. After the device is fixed, the detection work of the foundation pile begins. First, start the cylinder 4 installed on the base 1. The extension end of the cylinder 4 starts to extend and push the clamping plate 5 fixedly connected thereto to move towards the foundation pile. With the movement of the clamping plate 5, it gradually approaches the foundation pile and exerts a clamping force on the foundation pile to firmly fix it, ensuring that the position of the foundation pile is stable during the subsequent detection process and will not shift or move. After the foundation pile is fixed, the hydraulic cylinder 7 installed on the fixing frame 6 is started. The extension end of the hydraulic cylinder 7 starts to extend and push the connecting block 8 to move downward. The connecting block 8 is provided with a pressure sensor 9 inside. With the descent of the connecting block 8, the pressure sensor 9 gradually approaches the foundation pile. A protective shell 105 is also installed on the fixing frame 6. The pressure sensor 9 is located inside the protective shell 105 during the descent process. The protective shell 105 can prevent dust, debris and other external factors from interfering with or damaging the pressure sensor 9. When the pressure sensor 9 comes into contact with the foundation pile, the hydraulic cylinder 7 continues to work and continuously exerts pressure on the foundation pile. In this process, the pressure sensor 9 monitors the pressure it receives in real time and transmits the monitored pressure data out. The operator can analyze and evaluate the compression resistance of the foundation pile according to these data. In the long-term use process, if the pressure sensor 9 is damaged or needs to be replaced periodically, the operator pulls the pull rod 102 which is slidingly connected inside the connecting block 8. When the pull rod 102 moves, it drives the extrusion plate 106 fixedly connected thereto to move. The extrusion plate 106 compresses the spring 101 and at the same time makes the clamping block 103 fixedly connected to the inside of the pull rod 102 slide out of the clamping groove 104 opened in the pressure sensor 9. When the clamping block 103 completely slides out of the clamping groove 104, the fixing state of the pressure sensor 9 is released. The operator can take out the old pressure sensor 9 from the protective shell 105. After taking out the old sensor, the operator puts the new pressure sensor 9 into the protective shell 105 and aligns the clamping groove 104 with the position of the clamping block 103. Then, the pull rod 102 is loosened. At this time, the compressed spring 101 starts to recover the deformation and pushes the extrusion plate 106 to reset. The extrusion plate 106 drives the pull rod 102 to move, so that the clamping block 103 slides into the clamping groove 104 of the new pressure sensor 9, completing the replacement work of the pressure sensor 9.
