Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

The free end of the wire harness is connected with a transmitting and receiving probe. The probe is a sound wave transmitter and a sound wave receiver. The sound wave transmitter is used to generate and send sound wave signals to the top of the object to be measured (such as a pile foundation), and the sound wave receiver is used to receive the sound wave signals reflected from the bottom of the object to be measured; the signal processing unit of the sonic penetration method is used to process the sound wave signals obtained from the receiver and analyze its characteristics to infer the internal structure of the object to be measured. The sonic penetration method is usually equipped with a data recording and analysis system for recording and storing the data obtained from the signal processing unit and performing subsequent analysis and processing for pile foundation quality detection; an arrangement assembly is placed on one side of the bracket plate 3, and the arrangement assembly includes a moving block 6 for arranging the wire harness and a driving part for driving the moving block 6 to reciprocate; a cleaning assembly is placed above the moving seat 1, and the cleaning assembly includes a support frame 12. An upper guide wheel 15 and a lower guide wheel 16 for guiding the wire harness are arranged in the support frame 12, and a cleaning wheel 17 for cleaning the outer wall of the wire harness is arranged on one side of the support frame 12.

[0025] It should be noted that the utility model detects the bridge pile foundation through the sonic logging method. The device is moved to the designated position by the moving seat 1. The probe is placed in the sonic logging tube pre-buried when the steel reinforcement cage of the pile body is lowered. The tube is filled with clear water. The transmitting and receiving probes are placed at the bottom of the tube. The second motor 9 drives the wire winding shaft 4 to rotate to wind up the wire harness connected to the probe. During this period, the first motor 8 drives the moving block 6 to reciprocate in front of the wire winding shaft 4 to orderly arrange the wire harness, so as to realize the stable rising of the probe, send the sound wave into the pile foundation to be tested, part of the energy will be reflected back, and the other part will penetrate the pile foundation and spread to the surrounding soil or rock. The receiver receives the sound wave reflected from the bottom of the pile foundation and analyzes the characteristics of the reflected wave, such as intensity, propagation time, etc.; by analyzing the nature of the reflected wave, the internal structure of the pile foundation can be inferred. During the process of winding up the wire harness, the cleaning wheel 17 cleans the wire harness through friction to ensure that there are no foreign objects on the outside. And under the squeezing action of the upper guide wheel 15 and the lower guide wheel 16, the outside moisture can be scraped off to make it as dry as possible when winding up, so as to avoid repeatedly pulling up manually with gloves.

[0026] Please refer to Figure 1 、 3 As shown, it further includes a support plate 2 fixedly connected to the top of the moving seat 1.

A limiting tooth cooperating with the limiting disk 20 is provided on one side of the limiting rod 11 for limiting the position of the regulating placement plate 19. A second spring 21 is sleeved between the end of the limiting rod 11 and the support block.

[0027] It should be noted that the analysis instrument connected to the probe of the utility model is placed outside the regulating placement plate 1. The position of the regulating placement plate 19 is adjusted according to the observation angle. When adjusting, the limiting rod 11 is pulled towards one end to separate the limiting tooth from the limiting disk 20, and the second spring 21 is compressed by one end of the limiting rod 11. When the limiting rod 11 is separated from the limiting disk 20, the limiting rod 11 is rotated to adjust the angle of the regulating placement plate 19. When the regulating placement plate 19 is rotated to the designated angle, the limiting rod 11 is inserted into the slot of the limiting disk 20 at the corresponding position, and the second spring 21 resets to clamp the limiting tooth in the limiting disk 20, so as to facilitate the adjustment according to the observation angle and make the device structure more flexible.

[0029] It should be noted that three wire take-up reels 4 are provided in the present utility model. The three wire take-up reels 4 are fixedly connected to each other. The second motor 9 drives the wire take-up reel 4 to rotate inside the support plate 3 to wind up the wire harness. And the moving block 6 corresponds to the wire take-up reel 4 one by one. A sliding groove for the moving block 6 to slide is provided in the middle of the cross plate 5. Two cylinders are vertically rotatably arranged in the middle of the moving block 6 and two cylinders are horizontally rotatably arranged.
