[0002] In modern engineering construction, especially in large-scale infrastructure projects such as bridges and high-rise buildings, the quality of pile foundations is of paramount importance. As an important testing tool, sonic logging tubes provide an efficient, accurate, and non-destructive solution for pile foundation quality testing. After the pile foundation is poured, ultrasonic waves are emitted into the sonic logging tube to detect the integrity of the pile foundation, the density of the concrete, and the presence of defects, providing a strong guarantee for the quality control of engineering construction. Traditional sleeve-type sonic logging tubes need to be welded before use.
[0003] However, with current technology, the welding process is time-consuming, increasing the overall construction time, and is prone to welding defects, affecting the sealing of the joints. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a weld-free sleeve-type sonic logging tube, which aims to improve the problems of long welding time and easy welding defects that affect the sealing of the connection.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A weld-free sleeve-type sonic logging tube includes a first sonic logging tube, a positioning tube fixedly connected to the outer wall of the first sonic logging tube, a fixing groove formed inside the positioning tube, a sliding plate slidably connected to the inner wall of the positioning tube, the outer wall of the sliding plate slidably connected to the inner wall of the fixing groove, a spring fixedly connected to the lower surface of the sliding plate, the bottom end of the spring fixedly connected to the inner wall of the fixing groove, a locking block fixedly connected to the upper surface of the sliding plate, a beveled ring fixedly connected to the outer wall of the positioning tube, and a second sonic logging tube provided on both the beveled ring and the outer wall of the positioning tube, a limiting groove formed inside the second sonic logging tube, the outer wall of the locking block being disposed on the inner wall of the limiting groove, and a fixing component provided on the outer wall of the first sonic logging tube.
[0007] Preferably, the fixing component includes a locking sleeve, the inner wall of which is disposed on the outer wall of the first acoustic tube, the inner wall of which is disposed on the outer wall of the second acoustic tube, and a fixing box is fixedly connected to the outer wall of the locking sleeve.
[0008] Preferably, a nut is rotatably connected to the outer wall of the fixing box, and a positive and negative screw is fixedly connected to the outer wall of the nut. The outer wall of the positive and negative screw is rotatably connected to the inner wall of the fixing box.
[0009] Preferably, the inside of the fixing box is provided with a sliding groove, the outer wall of the positive and negative lead screws is rotatably connected to the inner wall of the sliding groove, and a limit plate is fixedly connected to the middle outer wall of the positive and negative lead screws.
[0010] Preferably, the outer wall of the positive and negative lead screw is threaded with a movable block, and the outer wall of the movable block is slidably connected to the inner wall of the slide groove.
[0011] Preferably, a support plate is fixedly connected to the lower surface of the movable block, and a connecting column is fixedly connected to the outer wall of the support plate.
[0012] Preferably, a transmission plate is rotatably connected to the outer wall of the connecting column, and a limit block is rotatably connected to the outer wall of the transmission plate.
[0013] Preferably, the outer wall of the limiting block is slidably connected to the inside of the locking sleeve, the inside of the locking sleeve is provided with a connecting groove, and the outer wall of the limiting block is disposed on the outer wall of the first acoustic tube and the second acoustic tube.
[0014] This utility model has the following beneficial effects:
[0015] 1. In this utility model, when the positioning tube is inserted into the second acoustic tube and the locking block slides to the position of the limiting groove, the spring rebounds through the fixing groove and pushes the locking block to slide to the inner wall of the limiting groove, thereby realizing the splicing and fixing of the acoustic tube. At the same time, the assembled inclined ring fits against the inner wall of the second acoustic tube, increasing the contact area, thereby achieving the effect of rapid splicing of the acoustic tube and improving the sealing of the connection.
[0016] 2. In this utility model, by turning the nuts at both ends of the outer wall of the locking sleeve, the positive and negative screws are driven to rotate on the inner wall of the slide groove. The positive and negative screws cause the moving blocks at both ends of the outer wall to move relative to each other through the threads. The connecting column is driven to move through the support plate, which in turn drives the transmission plate to rotate, so that the limiting block slides inside the locking sleeve and presses and fixes the outer wall of the sonic logging tube, thereby preventing the loosening and displacement of the connection of the sonic logging tube and improving the connection stability.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0024] Reference Figure 1 - Figure 3 An embodiment of this utility model provides: a weld-free sleeve-type acoustic logging tube, including a first acoustic logging tube 1, a positioning tube 2 fixedly connected to the outer wall of the first acoustic logging tube 1, a fixing groove 3 opened inside the positioning tube 2, a sliding plate 4 slidably connected to the inner wall of the positioning tube 2, the outer wall of the sliding plate 4 slidably connected to the inner wall of the fixing groove 3, a spring 5 fixedly connected to the lower surface of the sliding plate 4, the bottom end of the spring 5 fixedly connected to the inner wall of the fixing groove 3, a locking block 6 fixedly connected to the upper surface of the sliding plate 4, a bevel ring 20 fixedly connected to the outer wall of the positioning tube 2, a second acoustic logging tube 7 provided on both the bevel ring 20 and the outer wall of the positioning tube 2, a limiting groove 8 opened inside the second acoustic logging tube 7, the outer wall of the locking block 6 is set on the inner wall of the limiting groove 8, and a fixing component is provided on the outer wall of the first acoustic logging tube 1;
[0025] Specifically, the first acoustic tube 1 provides fixed support for the positioning tube 2, and the positioning tube 2 also serves to position the first acoustic tube 1 during assembly. The fixing groove 3 on the positioning tube 2 supports the sliding position of the sliding plate 4 and limits its movement. The sliding plate 4 provides fixed support for the spring 5, which can rebound through the fixing groove 3 to push the spring 5 upward on the inner wall of the fixing groove 3. The sliding plate 4 also provides fixed support for the locking block 6, which can be pushed upward to fit against the inner wall of the limiting groove 8 on the second acoustic tube 7, thereby fixing the positions of the first acoustic tube 1 and the second acoustic tube 7. At the same time, the positioning tube 2 provides fixed support for the inclined ring 20, which can fit against the inner wall of the second acoustic tube 7 during assembly to increase the contact area and improve the sealing effect.
[0026] Reference Figure 1and Figure 4 The fixing assembly includes a locking sleeve 21, the inner wall of which is disposed on the outer wall of the first acoustic tube 1 and the outer wall of the second acoustic tube 7. A fixing box 9 is fixedly connected to the outer wall of the locking sleeve 21. A nut 10 is rotatably connected to the outer wall of the fixing box 9. A positive and negative screw 11 is fixedly connected to the outer wall of the nut 10. The outer wall of the positive and negative screw 11 is rotatably connected to the inner wall of the fixing box 9.
[0027] Specifically, the locking sleeve 21 can ensure the positioning of the first acoustic tube 1 and the second acoustic tube 7 when they are spliced. At the same time, the locking sleeve 21 supports the first acoustic tube 1 and the second acoustic tube 7, which can ensure the stability of their connection. The locking sleeve 21 also provides fixed support for the fixing box 9. The fixing box 9 can support the rotation position of the nut 10. When the nut 10 rotates, it can drive the positive and negative screws 11 to rotate. The fixing box 9 can ensure the stability of the positive and negative screws 11 during rotation.
[0028] Reference Figure 1 and Figure 4 The fixed box 9 has a sliding groove 18 inside. The outer wall of the positive and negative lead screw 11 is rotatably connected to the inner wall of the sliding groove 18. The middle outer wall of the positive and negative lead screw 11 is fixedly connected to the limiting plate 12. The outer wall of the positive and negative lead screw 11 is threadedly connected to the moving block 13. The outer wall of the moving block 13 is slidably connected to the inner wall of the sliding groove 18. The lower surface of the moving block 13 is fixedly connected to the support plate 14. The outer wall of the support plate 14 is fixedly connected to the connecting column 15. The outer wall of the connecting column 15 is rotatably connected to the transmission plate 16. The outer wall of the transmission plate 16 is rotatably connected to the limiting block 17. The outer wall of the limiting block 17 is slidably connected to the inside of the locking sleeve 21. The inside of the locking sleeve 21 has a connecting groove 19. The outer wall of the limiting block 17 is set on the outer wall of the first acoustic tube 1 and the second acoustic tube 7.
[0029] Specifically, the slide groove 18 can ensure the position of the positive and negative lead screws 11 when rotating, and the positive and negative lead screws 11 have a fixed support function for the limiting plate 12. The limiting plate 12 has a limiting function for the movement position of the moving block 13. The positive and negative lead screws 11 can drive the moving blocks 13 on both ends of the outer wall to move relative to each other through the thread. The slide groove 18 can support the sliding position of the moving block 13. The moving block 13 has a fixed support function for the support plate 14. When the moving block 13 moves, it can drive the support plate 14 to move synchronously. The support plate 14 can support the position of the connecting column 15 and ensure the stability of the connecting column 15. The connecting column 15 can support the rotation position of the transmission plate 16. Then, the connecting column 15 can push or pull the transmission plate 16 to rotate on the inner wall of the limiting block 17. The limiting block 17 can slide inside the locking sleeve 21 by the push or pull of the transmission plate 16 until it is in contact with the outer wall of the first acoustic tube 1 and the second acoustic tube 7, so that it can be pressed and fixed to ensure the stability of the connection.
[0030] Working principle: When the acoustic logging tube is needed, firstly, the positioning tube 2 fixed to the first acoustic logging tube 1 is aligned with the inner wall of the second acoustic logging tube 7 using the locking sleeve 21. Simultaneously, the position of the locking block 6 corresponds to the parallel position of the limiting groove 8. Then, the positioning tube 2 is inserted into the inner wall of the second acoustic logging tube 7 within the locking sleeve 21. When the locking block 6 slides to the position of the limiting groove 8, the spring 5 rebounds through the fixing groove 3, which in turn pushes the sliding plate 4 upwards until the locking block 6 slides to the inner wall of the limiting groove 8. This allows the first acoustic logging tube 1 and the second acoustic logging tube 7 to be spliced and fixed, enabling rapid assembly. After assembly, the inclined ring 20 fits against the inclined surface of the inner wall of the second acoustic logging tube 7, increasing the contact area and further ensuring the sealing performance when the first acoustic logging tube 1 and the second acoustic logging tube 7 are connected. Then, tighten the nuts 10 at both ends of the outer wall of the locking sleeve 21. The nuts 10 can drive the positive and negative screws 11 to rotate on the inner wall of the slide groove 18. At this time, the positive and negative screws 11 drive the moving blocks 13 at both ends of their outer walls to move relative to each other through the threaded connection. The support plate 14 can drive the connecting column 15 to move, and then the connecting column 15 can push the transmission plate 16 to rotate. Then the transmission plate 16 can drive the limiting block 17 to slide inside the locking sleeve 21 until the outer walls of the first sonic logging tube 1 and the second sonic logging tube 7 are pressed and fixed, thereby preventing the sonic logging tube from loosening or displacing. That is, the sonic logging tube can not only achieve rapid assembly, greatly saving installation time and improving construction efficiency, but also effectively prevent the sonic logging tube from loosening and displacing, ensuring the reliability of sonic logging data.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
