Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please refer to Figure 1-3 As shown, this utility model provides a detachable and modular detection instrument for highway bridge pile foundation testing, including a trolley 1, a support plate 2, and a sleeve 3. The support plate 2 is provided in multiple sets. The lower end of the support plate 2 is fixedly installed on the upper surface of one end of the trolley 1, and a limiting groove 8 is opened on the side surface. The sleeve 3 is fixedly installed on the upper surface of the other end of the trolley 1, and a first locking bolt 4 is threadedly connected to one side of the sleeve 3. A support assembly is detachably installed inside the sleeve 3, and a winding assembly is provided on the inner side of the support plate 2.

[0016] Specifically, this utility model disassembles the detection instrument into multiple modules such as a trolley 1, a support component, a winding component, and a receiving terminal 6. The modules are detachably connected, allowing for quick disassembly and assembly on-site as needed. After disassembly, each module is small in size and light in weight, making it easy to transport on complex terrain construction sites. This effectively avoids the influence of obstacles such as ditches and fences, reducing the labor intensity of the testing personnel. The disassembly and assembly of each module does not require complex tools; it can be quickly fixed by tightening bolts and engaging structures. The cable box 14 enables the rapid winding and unwinding of the detection cable, and with the help of pulleys for guidance, it further enhances the convenience of the testing operation.

[0017] The support components include a telescopic rod 9, a second locking bolt 10, a mounting bracket 11, and a pulley 12. The fixed end of the telescopic rod 9 is detachably installed inside the sleeve 3. The second locking bolt 10 is threadedly connected to one side of the fixed end of the telescopic rod 9. The mounting bracket 11 is fixedly installed on the top of the telescopic end of the telescopic rod 9. The pulley 12 is located inside the mounting bracket 11, with its two ends rotatably installed on the inner walls of both ends of the mounting bracket 11. By adopting a design where the telescopic rod 9 can be detachably installed on the sleeve 3, the telescopic length can be flexibly adjusted in conjunction with the second locking bolt 10, thereby adjusting the height of the top mounting bracket 11 and the pulley 12. The pulley 12 achieves smooth guidance of the detection cable through rotational installation, reducing the friction of the cable during release or retrieval and avoiding cable wear. The mounting bracket 11 provides a stable rotating mounting base for the pulley 12, ensuring the structural stability of the pulley 12.

[0018] The winding assembly includes a cable box 14 and a locking block 15. The locking block 15 is fixedly installed at the center of both sides of the cable box 14. The locking block 15 engages with the limiting groove 8 and can slide inside the limiting groove 8. The cable box 14 is an automatic winding cable box with a built-in coil spring and damping structure, which can realize the automatic recycling and smooth release of the detection cable. It is set on the inner side of every two sets of support plates 2. Through the one-to-one correspondence between the first limiting ring 5 and the cable box 14, it can accurately guide the detection cable released from the cable box 14, limit the deviation direction of the cable, avoid the cables of multiple sets of cable boxes 14 from getting tangled, and ensure that the cable is transmitted to the subsequent guiding structure along the preset path, thereby improving the stability of cable transmission. The cable box 14 can realize the automatic winding and unwinding of the detection cable without the need for manual cable handling, thus improving the efficiency of cable winding and unwinding; at the same time, it plays a role in storing and protecting the cable.

[0019] Among them, a first limiting ring 5 is installed on one side of the support plate 2. There are multiple sets of first limiting rings 5, which correspond to multiple sets of cable boxes 14. By setting the first limiting rings 5 ​​and cable boxes 14 in a one-to-one correspondence, the detection cable released from the cable box 14 can be accurately guided, limiting the offset direction of the cable, avoiding the cables of multiple sets of cable boxes 14 from getting tangled together, and ensuring that the cable is transmitted to the subsequent guiding structure along the preset path, thereby improving the stability of cable transmission.

[0020] Specifically, a second limiting ring 13 is fixedly installed on the inner wall of one side of the mounting bracket 11. Multiple sets of the second limiting ring 13 are provided and correspond to the grooves of the locking block 15. Through the corresponding arrangement of the second limiting ring 13 and the grooves of the locking block 15, the guiding function of the first limiting ring 5 is carried out to perform secondary precise limiting on the detection cable, further constraining the transmission path of the cable and preventing the cable from deviating or shaking before and after passing around the pulley 12. At the same time, it works with the first limiting ring 5 to form a complete cable guiding channel, ensuring that the cable maintains a stable posture during the winding and unwinding process and improving the reliability of detection data transmission.

[0021] Specifically: A support base 7 is fixedly installed on the upper surface of one end of the trolley 1. A receiving terminal 6 is detachably installed on the inner side of the upper end of the support base 7. The support base 7 provides a stable mounting point for the receiving terminal 6, ensuring that the receiving terminal 6 is placed stably during the testing process. The detachable connection design between the receiving terminal 6 and the support base 7 allows the receiving terminal 6 to be disassembled and transported separately, reducing the overall transport weight. At the same time, it facilitates the testing personnel to flexibly pick up and put down the receiving terminal 6 according to the operational needs, improving data viewing.

[0022] Working principle: This utility model is a detachable and modular detection instrument for highway bridge pile foundation testing. When used on-site for highway bridge pile foundation testing, the instrument is first assembled: the fixed end of the telescopic rod 9 is inserted into the sleeve 3, and the first locking bolt 4 is tightened to fix the telescopic rod 9; the telescopic length of the telescopic rod 9 is adjusted according to the testing requirements, and after adjustment, the second locking bolt 10 is tightened to fix it; the cable box 14 is installed in the limiting grooves 8 of the two sets of support plates 2 by the locking blocks 15 on both sides; the detection cable is pulled out from the cable box 14, passes through the corresponding first limiting ring 5 and second limiting ring 13 in sequence, and goes around the pulley 12; the detection probe at the end of the cable is placed into the pile foundation; the receiving terminal 6 is mounted on the support base 7 and electrically connected to the detection cable, completing the assembly.

[0023] During the testing process, the entire instrument can be moved by pushing the trolley 1, facilitating switching between multiple pile foundation testing points. After the testing is completed, the instrument is disassembled: disconnect the receiver terminal 6 from the testing cable and remove the receiver terminal 6; remove the testing probe from the pile foundation, and the cable will automatically retract under the action of the tension box 14; remove the box 14 from the limiting groove 8 of the support plate 2; loosen the first locking bolt 4 and pull the telescopic rod 9 out of the sleeve 3; complete the disassembly of each module, and then transport the disassembled modules to the designated location for storage or transportation.
