Description

Technical Field

[0001] This invention relates to the field of hole and grooving quality inspection technology, specifically to a freely combinable multifunctional hole and grooving quality inspection device and a cable synchronous control method. Background Technology

[0002] Hole and trench quality inspection is crucial for ensuring the safety of infrastructure such as bored piles, slab piles, and diaphragm walls. It directly determines the bearing capacity and stability of the pile foundation, allowing for timely detection of defects such as hole diameter and verticality, avoiding rework losses, and meeting industry standard acceptance requirements to ensure the long-term safe operation of the project. The ultrasonic hole and trench quality inspector, a specialized device for inspecting the quality of pile foundation hole and trench construction, is a professional instrument that uses ultrasonic technology to perform high-precision, non-destructive testing of key parameters such as hole diameter (groove width), verticality, and hole wall condition. This instrument provides a "visual" assessment of drilling quality, ensuring project safety and bearing capacity.

[0003] Hole and grooving quality inspection instruments have undergone multiple upgrades, evolving from low-precision inspection using simple manual tools to semi-automatic quantitative inspection equipment. Now, they have entered a fully automatic and intelligent stage based on technologies such as ultrasonic waves and wireless communication, enabling simultaneous multi-parameter detection, automatic data analysis, and intelligent defect identification, making them suitable for complex engineering scenarios. Based on current industry trends and field feedback, miniaturization and portability of hole inspection equipment have become core technological development directions.

[0004] Common hole and trenching quality inspection equipment typically consists of an electrically controlled winch, an ultrasonic testing probe, and an operating terminal. The winch is placed above the hole to be tested, and the ultrasonic testing probe is suspended inside the hole via a cable for inspection. The probe transmits the detection signal from the hole wall to the winch in real time via the cable, and then to the operating terminal via wired or wireless communication. However, in this wired connection method, the cable not only serves as the signal communication carrier but also as the main load-bearing structure for the probe, making it prone to damage and shortening the equipment's lifespan. Furthermore, a single cable is easily tangled as the probe swings, reducing inspection efficiency. Although wireless communication technology can solve the above cable problems, when the hole to be tested is deep (hundreds of meters), the internal environment is complex, and there is virtually no wireless signal after the probe is deep enough to transmit the detection data back to the ground operating terminal for 3D hole mapping in real time. Testers cannot obtain real-time test results. Summary of the Invention

[0005] The purpose of this invention is to address the problems existing in the prior art by providing a small, lightweight, flexible, and freely combinable multifunctional hole and groove quality inspection device and a cable synchronous control method. It is compatible with both wired and wireless working modes. For deep hole testing scenarios, the wired working mode enables real-time uploading of test data and real-time image generation of test results. For shallow hole testing scenarios, the wireless working mode enables rapid and efficient testing with pre-testing and subsequent inspection.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: Firstly, a freely combinable, multifunctional hole-forming and grooving quality inspection device is provided, comprising: A wire winch, wherein the wire winch contains a wire rope, a counting module for counting the length of the wire rope being wound up and unwound, and a tension detection mechanism connected to the wire rope for monitoring the tension of the wire rope; An orifice frame is used to install at the orifice opening. The orifice frame has a first pulley at one end and a wire hook seat at the other end. A probe frame is located below the orifice frame. A smart probe is detachably connected to the probe frame. The wire rope is led out from the wire winch, passes through the first pulley and multiple second pulleys on the probe frame, and then connects to the wire hook seat. The smart probe is compatible with both wireless and wired connection modes, and transmits the collected test data to the operating terminal either delayed or in real time.

[0007] This modular, multifunctional hole-forming and grooving quality inspection equipment is highly flexible, allowing for free combination and deployment in various forms. It is also compact, lightweight, easy to transport, and convenient and efficient to install.

[0008] The freely combinable multifunctional hole-forming inspection device of the present invention is compatible with two working modes. Depending on the on-site construction environment, it can freely choose to adopt the efficient wireless working mode or the wired working mode that can observe and detect data in real time, making it flexible in use.

[0009] For deeper pile holes, regardless of whether the probe is equipped with a wireless transmission module, once inside the hole, due to the depth and complex environment (containing mud and other substances), the wireless signal cannot be transmitted directly from the probe to the ground smoothly, and is subject to significant interference. The probe needs to store the test data inside itself, and after the test is completed, the probe is removed from the hole, and the test data inside the probe is exported in order to obtain the data. This method is suitable for the hole-forming and trench-forming quality inspection of most pile holes, but it lacks real-time feedback.

[0010] The intelligent probe of the present invention is also compatible with wired working mode. It can be directly connected to the intelligent probe via cable, and the detection data monitored by the intelligent probe in real time can be directly transmitted to the ground, so that the ground staff can obtain relevant detection information in real time without delay.

[0011] Furthermore, the counting module includes a counting mounting base, a counting wheel is provided inside the counting mounting base, and a plurality of guide wheels located upstream and downstream of the counting wheel. A counter connected to the counting wheel is provided on the outer side of the counting mounting base. The tension detection mechanism is provided above the counting wheel and the adjacent guide wheel. The wire rope or cable is wound around one side of the guide wheel, connected to the tension detection mechanism, and then wound around the counting wheel and the other side of the guide wheel.

[0012] Furthermore, the tension detection mechanism includes a support frame disposed on the counting mounting base (on the counting module), a connecting sleeve disposed within the support frame, an axially movable spring pin disposed within the connecting sleeve, and a spring sleeved on the spring pin, one end of the spring pin extending out of the connecting sleeve and having a connecting hole through which the wire rope or cable passes; a jog button is disposed on the support frame corresponding to the end of the connecting sleeve, the other end of the spring pin contacting the jog button when the wire rope or cable is in a slack state, and / or, a sensing sensor is disposed within the counting mounting base to sense whether the wire rope or cable has passed by, in order to determine whether the wire rope or cable is in a slack state.

[0013] Furthermore, the smart probe integrates a wireless transmission module and a built-in battery, as well as a power switch knob and a battery charging port. In wireless connection mode, after the smart probe is removed from the hole, the wireless transmission module communicates with the operating terminal to transmit test data. The smart probe is also equipped with a cable socket connector. In wired connection mode, the cable socket connector is directly connected to the repeater box via a cable. The smart probe transmits test signals to the repeater box in real time under the hole, and the repeater box communicates with the operating terminal to transmit test data in real time.

[0014] Furthermore, the orifice frame is also equipped with a detachable relay box, inside which is a winding reel. A cable is wound on the winding drum of the reel, and the cable is connected to the smart probe. Inside the winding drum is a drive motor that connects to and drives the winding drum to rotate. The relay box is also equipped with a relay box power supply and a control circuit board. The control circuit board is electrically connected to the drive motor and communicates with the operating terminal.

[0015] Furthermore, a counting module and a tension detection mechanism are also provided inside the lower part of the relay box. The bottom of the relay box has a hollow structure. The cable led out from the winding drum is connected to the counting module and the tension detection mechanism and then connected to the smart probe. The counting module is used to count the length of the cable winding and unwinding, and the tension detection mechanism is used to monitor the tension status of the cable.

[0016] Furthermore, the tension detection mechanism is mounted on the counting module, and a movable seat is also provided on the side of the tension detection mechanism. The wire winch and the relay box are respectively provided with transmission rods connected to the movable seat. During the winding and unwinding of the wire rope, the counting module and the tension detection mechanism in the wire winch move synchronously with the axial movement of the wire rope. During the winding and unwinding of the cable, the counting module and the tension detection mechanism in the relay box move synchronously with the axial movement of the cable.

[0017] Secondly, a cable synchronization control method is provided for a freely combinable multifunctional hole-forming and grooving quality inspection device. In the cable connection mode, the wire rope and the cable need to be synchronously wound and unwound. The cable synchronization control method is as follows: The running speed V1 of the wire rope is obtained by the counting module in the wire winch, and the tension signal S1 of the wire rope is obtained by the tension detection mechanism of the wire winch. The tension signal S1 is divided into two states: slack and tension. The cable's running speed V2 is obtained through the counting module in the relay box, and the cable's tension signal S2 is obtained through the tension detection mechanism and drive motor in the relay box. The tension signal S2 is divided into three states: slack, slightly tense, and over-limit. When V1=V2, it is determined that the wire rope and the cable are in a synchronized state, and the equipment is in good working condition; When V1≠V2, if S1 is in a tensioned state, S2 is in a slightly tensioned state, and V1<V2, the wire rope release speed is increased; if S1 is in a tensioned state, S2 is in a slightly tensioned state, and V1>V2, the wire rope take-up speed is decreased. When V1≠V2, if S1 is in a relaxed state, adjust the winding and unwinding speed of the wire rope to bring it into a taut state; if S1 is taut and S2 is relaxed, control the winding and unwinding speed of the cable until S2 is slightly taut, and then reduce V2 to the same speed as V1; if both S1 and S2 are relaxed, the smart probe will touch the bottom. When S2 is in an out-of-range state, an alarm is sent to the operation terminal. At the same time, the speed of the drive motor in the relay box is adjusted to reduce the tension on the cable until the cable is in a slightly taut state.

[0018] The cable's operating speed V2 is directly obtained by calculating the cable's take-up and undo length per unit time using the counting module in the repeater box. The calculation expression for the wire rope's operating speed V1 is: V1=La*sinθ / t, In the formula, La is the distance between the first pulley and the second pulley, La=(Lx+2Lc) / 2, Lx is the real-time wire rope length calculated by the wire rope counting module, Lc is the horizontal distance between the first pulley and the second pulley, which is related to the geometric dimensions of the probe frame and the orifice frame structure and is a fixed value; θ is the horizontal angle between the first pulley and the second pulley, θ=arccos(Lc / La); t is the running time of the intelligent probe.

[0019] The method for determining the state of the tension signal is as follows: The tension signal S1 of the wire rope is determined by whether the jog button in the tension detection mechanism is triggered or whether the sensor has a signal. When the jog button is triggered or the sensor has a signal, it indicates that the wire rope is in a slack state. When the jog button is not triggered or the sensor has no signal, it indicates that the wire rope is in a tensioned state. The cable tension signal S2 is determined by whether the jog button of the tension detection mechanism is triggered or whether the sensor has a signal, and whether the current of the drive motor in the relay box exceeds the limit. When the jog button is triggered or the sensor has a signal, it indicates that the cable is in a slack state. When the jog button is not triggered or the sensor has no signal and the current of the drive motor in the relay box is normal, it indicates that the cable is in a slightly tensioned state. When the jog button is not triggered or the sensor has no signal and the current of the drive motor in the relay box exceeds the limit, it indicates that the cable is in an over-limit state.

[0020] Compared with existing technologies, the beneficial effects of this invention are as follows: 1. This freely combinable multifunctional hole and groove quality inspection equipment, through modular design, is not only compact, lightweight, and convenient to transport and install, but also compatible with two working modes. It can freely choose between an efficient wireless working mode or a wired working mode that allows real-time monitoring of inspection data, depending on the site environment, offering flexibility in use. 2. In construction scenarios where both deep and shallow holes need to be inspected simultaneously, to improve work efficiency, a wireless working mode can be used to inspect shallow holes, which is simple and quick to operate; a wired working mode can be used to inspect deep holes, improving the accuracy of inspection data and the first-time success rate. This hybrid application effectively improves inspection efficiency and reduces workload. 3. This inspection equipment and its supporting cable synchronous winding and unwinding control method integrate multi-parameter control strategies, making the steel wire rope the main load-bearing cable, playing a leading role in winding and unwinding, while the relay box acts as a follow-up system, with the cable subjected to only a small force and in a state of slight tension. The system features several key features: 1. **Protecting signal cables and extending their lifespan:** It also allows for synchronized winding and unwinding of wire rope and cable, preventing cable tangling and improving work efficiency. 2. **The wire rope winch can hold hundreds of meters of wire rope. If a frequently used section of the wire rope is damaged, the damaged section can be cut off, and a new unused section can be pulled from the drum for continued use, effectively reducing equipment maintenance frequency and increasing winch lifespan. 3. **The intelligent probe, equipped with a built-in battery, can wirelessly transmit and receive signals. In wired mode, it intelligently determines the working status, prioritizing external power supply. If external power is disconnected, it can switch to internal power supply, providing double power insurance and improving probe reliability. 4. **Integrating the counting module and tension detection mechanism, located in the wire rope winch and relay box respectively, allows for counting the winding and unwinding length of the wire rope and cable, thus obtaining the vertical distance the probe travels within the hole. It can also detect whether the wire rope and cable are under tension and determine if the probe has touched the bottom.** Attached Figure Description

[0022] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing this invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] Example 1: A freely combinable multifunctional hole-forming and grooving quality inspection device is provided, such as... Figures 1-4 As shown, it includes: The wire winch 1 contains a wire rope 4, a counting module 2 for counting the length of the wire rope 4 being wound up and unwound, and a tension detection mechanism 3 connected to the wire rope 4 and used for monitoring the tension of the wire rope 4. An orifice frame 5 is used to install at the orifice opening. One end of the orifice frame 5 is provided with a first pulley 6 and the other end is provided with a wire hook seat 7. A probe frame 8 is provided below the orifice frame 5. A smart probe 10 is detachably connected to the probe frame 8. The wire rope 4 is led out from the wire winch 1, passes through the first pulley 6 and multiple second pulleys 9 on the probe frame 8, and is connected to the wire hook seat 7. The smart probe 10 is compatible with both wireless and wired connection modes and transmits the collected test data to the operating terminal either delayed or in real time.

[0025] This modular, multifunctional hole-forming and grooving quality inspection equipment is not only compact, lightweight, and easy to transport and install, but also compatible with two working modes. Depending on the site environment, users can freely choose between an efficient wireless working mode or a wired working mode that allows for real-time monitoring of inspection data, making it highly flexible in use.

[0026] This embodiment first describes in detail the various components mounted on the testing equipment in a wireless connection mode.

[0027] The wire rope winch 1 is configured to wind up and unwind the wire rope 4, which can be pulled to the opening of the pile hole and connected to the opening frame 5 and probe frame 8 erected at the opening. The wire rope is released during the descent of the intelligent probe 10 and wound up when the intelligent probe 10 needs to rise. Furthermore, the counting module 2 built into the winch can acquire the speed and displacement (length) of the wire rope winding up and unwinding in real time, and the tension detection mechanism 3 can monitor the tension of the wire rope in real time and acquire corresponding signal data, providing reliable data support for subsequent cable control.

[0028] In this embodiment, the wire rope winch 1 adopts a single-drum structure as the wire rope winding drum. The winch frame is welded from stainless steel pipes, ensuring the overall strength of the equipment. The wire rope winding drum is a single-drum multi-layer winding structure, capable of accommodating several times the length (hundreds of meters) of wire rope. If a frequently used section of the wire rope is damaged, the damaged section can be directly cut off, and a new unused section can be pulled from the winding drum for continued use, effectively reducing the frequency of equipment maintenance and increasing the service life of the winch. A wire rope counting module is designed, whose main function is to count the length of the wire rope wound and unwound, thereby obtaining the vertical distance the probe travels within the hole, i.e., the real-time depth of the probe's movement within the hole. This module also includes a wire rope tension detection mechanism to detect whether the wire is under tension and to determine whether the probe has touched the bottom. The wire rope winding drum is connected to a reduction gear drive motor via a sprocket and chain, with the reduction gear providing power to the wire rope winding drum. The electrical control box for the wire rope winch is located on top of the winch. The control box is fixed with screws and sealed with silicone sealant.

[0029] The orifice frame 5 can be freely erected above the orifice. The probe frame 8 is located below the orifice frame 5 and is not directly connected to it. The probe frame 8 is connected to the wire rope 4 only by the second pulley 9 on it, making the installation simple and convenient. The wire rope 4 passes through the first pulley 6 on the orifice frame, then winds around the second pulley 9 and connects to the wire hook seat 7 on the orifice frame, forming a structure that can achieve tension of the wire rope by relying on the gravity of the probe frame and the smart probe. Moreover, the smart probe 10 is lowered and retracted in a V-shape, which avoids the smart probe 10 swinging in all directions and makes the probe lifting and lowering operation more stable.

[0030] In some embodiments, a wire rope clamping mechanism 11 is also provided above the orifice frame, which can clamp the wire rope on the first pulley. The wire rope on the first pulley can be manually pressed into the wire rope clamping mechanism for clamping, which can temporarily fix the wire rope so as to facilitate the synchronous transport of the entire orifice frame, probe frame and smart probe.

[0031] In some embodiments, a wire rope anti-detachment structure 12 may be provided on the probe frame to limit the wire rope on the second pulley and prevent it from falling off the second pulley, thereby improving stability.

[0032] Furthermore, such as Figures 5-8As shown, the counting module 2 includes a counting mounting base 201, a counting wheel 203 is provided inside the counting mounting base 201, and a plurality of guide wheels 202 located upstream and downstream of the counting wheel 203. A counter 204 connected to the counting wheel 203 is provided on the outer side of the counting mounting base 201. The tension detection mechanism 3 is provided above the counting wheel 203 and the adjacent guide wheel 202. The wire rope or cable is wound around one guide wheel 202 and then connected to the tension detection mechanism 3, and then wound around the counting wheel 203 and the other guide wheel.

[0033] By configuring the guide wheel 202, the counting wheel 203, and the tension detection mechanism 3, not only can the wire rope be effectively guided to maintain a suitable tension, but it can also monitor in real time whether the wire rope is under tension. When under tension... Figure 8 The 306 button in the middle remains in an untriggered state; once... Figure 8 When button 306 is triggered, it indicates that the steel wire rope is in a slack state. It can also be used to determine whether the probe has touched the bottom.

[0034] Specifically, the tension detection mechanism 3 includes a support frame 301 mounted on the counting mounting base 201 (on the counting module). The support frame 301 has a connecting sleeve 302 inside, and the connecting sleeve 302 has an axially movable spring pin 303 inside, and a spring 304 sleeved on the spring pin 303. One end of the spring pin 303 extends out of the connecting sleeve 302 and has a connecting hole 305, through which the wire rope or cable passes. A jog button 306 is provided on the support frame 301 at a position corresponding to the end of the connecting sleeve 302. The other end of the spring pin 303 contacts the jog button 306 when the wire rope or cable is in a slack state.

[0035] The spring pin 303 can be connected to the wire rope 4 (or cable 23) via the connecting hole 305 at its end. When the wire rope 4 is in a tensioned state, the wire rope 4 fits well with the guide wheel 202 and the counting wheel 203, and the spring pin 303 is pulled out and close to the guide wheel 202 and the counting wheel 203. When the wire rope 4 is in a slack state, the spring pin 303 will move towards the end of the support frame 301 under the action of the preset spring 304 inside, that is, retract. At this time, the spring pin 303 will touch the jog button 306, thus knowing that the wire rope 4 is in a slack state or that the smart probe has reached the bottom.

[0036] The counting mounting base 201 is also equipped with a sensing sensor 307, which is used to sense whether the steel wire rope or cable passes by, so as to determine whether the steel wire rope or cable is in a slack state. For example, when the steel wire rope or cable passes by the sensing sensor, the sensing sensor generates a sensing signal, indicating that the steel wire rope or cable is in a slack state. When the steel wire rope or cable does not pass by (or does not pass through) the sensing sensor, the sensing sensor does not generate a sensing signal, indicating that the steel wire rope is in a taut state and the cable is in a non-slack state.

[0037] Integrating the counting module 2 and the tension detection mechanism 3 together not only facilitates their combined function but also optimizes the overall module structure, resulting in a smaller size and easier installation. Furthermore, by providing guide seats 20 and movable seats 19 on both sides of the support frame 301, it can be better positioned in the wire rope winch 1 or the relay box and can move horizontally during the wire rope winding and unwinding process.

[0038] Taking the counting module 2 and the tension detection mechanism 3 installed in the wire rope winch 1 as an example, the installation structure is described as follows: Figure 2 As shown, in the wire winch 1, the wire drum 14 is connected to the integrated reduction drive motor 13 via a first sprocket chain 15. Inside the wire winch 1, parallel to the central axis of the wire drum 14, there is a transmission rod 17 and a guide rod 18. The integrated reduction drive motor 13 is also connected to the transmission rod 17 via a second sprocket chain 16. The movable seat 19 is connected to the transmission rod 17 (similar to the structure of a lead screw and a lead screw sleeve). When the transmission rod 17 rotates, the movable seat 19 will move along the transmission rod 17. The guide seat 20 is slidably connected to the guide rod 18, which plays a guiding role and also makes the connection and installation of the counting module 2 and the tension detection mechanism 3 more stable. By adjusting the transmission ratio of the first sprocket chain 15 and the second sprocket chain 16, the integrated reduction drive motor 13 can drive the wire rope drum 14 to rotate and wind up and unwind the wire rope 4. Simultaneously, the transmission rod 17 can also drive the moving seat 19 to move, meaning the counting module 2 and the tension detection mechanism 3 move together. This avoids the problems of pulling and uneven movement that would occur if the wire rope 4 moved axially alone. A similar installation structure and principle for the counting module 2 and the tension detection mechanism 3 are also applicable to the relay box.

[0039] Furthermore, the smart probe 10 integrates a wireless transmission module (such as a Wi-Fi module), a built-in battery, a power switch knob, and a battery charging port. In wireless connection mode, after the smart probe 10 is removed from the hole, the wireless transmission module communicates with the operating terminal to transmit test data. The smart probe 10 is also equipped with a cable socket connector. In wired connection mode, the cable socket connector is directly connected to the repeater box via a cable. The smart probe transmits test signals to the repeater box in real time under the hole, and the repeater box communicates with the operating terminal to transmit test data in real time.

[0040] This smart probe 10 features a Wi-Fi module and a built-in battery, resulting in a longer battery life. The Wi-Fi antenna is located at the top of the probe, which also includes a power switch knob, cable socket connector, and battery charging port, enabling it to support two connection modes. To ensure waterproofing, the Wi-Fi antenna and power switch are waterproof, and the cable socket and charging port are sealed.

[0041] In wireless connection mode (wireless communication between the probe and the wire rope winch), after the wire rope winch and the smart probe are powered on, they will automatically connect wirelessly and communicate, transmitting the communication information back to the host computer. The host computer's data acquisition software determines that the system is in wireless mode. After the user sets relevant parameters, it issues control commands, such as probe acquisition and wire rope retraction / deployment commands, but does not perform real-time plotting. When the preset hole depth is reached or the wire rope bottom-touching judgment mechanism is triggered, the software clicks "test complete," records the time and depth information, and then raises the smart probe from the hole (no signal transmission inside the hole). After the smart probe and the winch reconnect, the probe's acquired data will be automatically transmitted to the winch, which in turn transmits it to the host computer software. This wireless mode is suitable for lightweight testing scenarios involving small, ordinary pile foundations, no regulatory requirements, flexible construction periods, and simple geological conditions. Its advantages are portability and operational flexibility.

[0042] Example 2: As Figure 9 and Figure 10 As shown, the difference between this embodiment and Embodiment 1 is that a relay box 21 is installed on the borehole frame 5, which is connected to the smart probe 10 via a wired connection. This connection method is not affected by the construction environment; even if the smart probe is inserted into a borehole with no wireless signal, it can still transmit the detection data to the ground in real time. It is suitable for scenarios such as ultra-deep pile foundation detection, real-time monitoring of smart construction sites, compliance acceptance of key projects, complex geological risk management, and on-site acceptance. The wired mode, with its core characteristics of real-time mapping, stable transmission, real-time data uploading to the blockchain, tamper-proof original data, and process traceability, not only possesses significant technical advantages but also meets the rigid requirements of industry regulatory standards, engineering quality control, and compliance acceptance of documents.

[0043] Specifically, a relay box 21 is also placed on the orifice frame 5. The relay box 21 is equipped with a winding reel 22. A cable 23 is wound on the winding drum of the winding reel 22. The cable 23 is connected to the smart probe 10. A drive motor is installed inside the winding drum to drive the rotation of the winding drum. The relay box 21 is also equipped with a relay box power supply and a control circuit board. The control circuit board is electrically connected to the drive motor and communicates with the operating terminal. It can also be connected to a wireless module installed inside the wire winch.

[0044] The repeater box 21 is a compact and portable cuboid structure that can accommodate 150m of cable. The cable 23 is a lightweight, non-load-bearing conductor. In wired connection mode, the repeater box 21 is directly connected to the smart probe 10, enabling real-time acquisition of test signals. These signals are then wirelessly transmitted via Wi-Fi to a winch for relay and finally to the customer's operating terminal. The repeater box 21 has a built-in drive mechanism, primarily consisting of a drive motor (direct-drive torque motor). The drive motor is integrated into the hollow space inside the winding drum of the winding reel. The inner ring of the drive motor module is fixed to the frame of the repeater box, while the outer ring is fixed to the winding reel via structural components. When the inner and outer rings of the motor module rotate relative to each other, the winding reel rotates. The repeater box 21 also includes a built-in battery and a control circuit board, which enables motor control, Wi-Fi communication, and probe signal acquisition. The repeater box battery provides long-lasting power for the device and can also power the smart probe when needed. For ease of cable routing, the bottom area of ​​the repeater box casing is left unopened.

[0045] Additionally, a counting module 2 and a tension detection mechanism 3 are also located inside the lower part of the relay box 21. The cable 23, led out from the reel, connects to the counting module 2 and the tension detection mechanism 3, and then to the smart probe 10. The counting module 2 is used to count the length of the cable 23 during winding and unwinding, and the tension detection mechanism 3 is used to monitor the tension status of the cable 23. This allows for matching with the speed of wire rope winding and unwinding, and the tensioning mechanism can detect whether the cable is under slight tension.

[0046] The wire rope winch 1 is powered by an external mobile power supply or 220V AC mains power, while the relay box 21 and the smart probe 10 are powered by built-in batteries and each has a power switch. After power is connected, the host computer connects to the wire rope winch's wireless WiFi and opens the acquisition software to perform corresponding control operations. At this time, the wire rope winch, relay box, and smart probe also need to communicate. The wire rope winch communicates wirelessly with the relay box, and the relay box communicates wiredly with the smart probe. The status of the relay box should be transmitted to the host computer (such as an operating terminal) via the winch and displayed on the acquisition software. When the wired status is determined, the borehole acquisition data should be transmitted in real time and plotted. In addition, during the entire system operation, the wire rope serves as the main load-bearing component of the probe, and the cable connecting the relay box and the smart probe only has a communication function. Therefore, the cable needs to be kept slightly taut to increase its service life.

[0047] Example 3: A cable synchronization control method is provided for a freely combinable multifunctional hole-forming and grooving quality inspection device. In the cable connection mode, the steel wire rope and the cable need to be synchronously wound and unwound. To avoid the steel wire rope from tangling with the relay box cable, the synchronization of the cable and the steel wire rope needs to be controlled.

[0048] There are four main factors that determine the steel wire rope and the cable: (1) The speed V1 of the wire rope in the direction of the smart probe's movement as follows Figure 11 As shown, the path of the wire rope running on the orifice frame and probe frame is simplified into a line diagram. In the diagram, La is the distance between the first and second pulleys. The orifice frame is fixed at the orifice opening, and the probe frame rises and falls together with the intelligent probe inside the orifice. Therefore, La changes as the intelligent probe moves up and down. Lb is the distance between a pair of second pulleys, and Lc is the horizontal distance between the first and second pulleys. Lb and Lc are determined by the geometric dimensions of the probe frame and orifice frame, and their values ​​are measurable and fixed. The angle between La and Lc (i.e., the horizontal angle between the first and second pulleys) is θ, which varies from 0° to 90° and gradually increases as the intelligent probe descends.

[0049] Let θ be the initial state of the equipment when it is 0. The wire rope is horizontally straightened after passing through the first pulley, the second pulley, and the wire hook seat. At this point, the probe is at the orifice. The initial descent depth of the intelligent probe in this state is recorded as 0, and the initial length of the wire rope is L0 = 2Lc + Lb. The wire rope counting module counts 0 in real time. As the intelligent probe descends, the θ value begins to increase. At this point, the wire rope counting module calculates the real-time output length as Lx. Lx - 0 = 2La + Lb - L0, so La = (Lx + 2Lc) / 2, θ = arccos(Lc / La), and the probe descent depth is H = La * sinθ. Therefore, the wire rope controls the probe descent speed V1 = H / t = La * sinθ / t (the derivation of V1 during the probe ascent and retrieval process is similar).

[0050] (2) Tension signal S1 of wire rope The wire rope tension signal S1 has two states: slack and tension. It is determined by whether the jog button of the tension detection mechanism inside the wire rope winch is triggered or whether the sensor has a signal. When the jog button is not triggered or the sensor has no signal, it indicates that the wire rope is in a tensioned state. When the jog button is triggered or the sensor has a signal, it indicates that the wire rope is in a slack state.

[0051] (3) The speed V2 of the cable in the direction of the smart probe's movement When the cable is directly connected to the smart probe, the cable's running speed V2 is the length of cable reeling in and out per unit time, which is directly calculated by the counting module in the repeater box.

[0052] (4) Cable tension signal S2 The cable tension signal S2 has three states: slack, slightly tensioned, and over-tensioned. This is determined by whether the jog button of the tension detection mechanism inside the repeater box is triggered, whether the sensor registers a signal, and whether the current of the repeater box's drive motor exceeds the limit. If the jog button is triggered or the sensor registers a signal, the cable is in a slack state. If the jog button is not triggered or the sensor registers a signal, and the current of the repeater box's drive motor is normal, the cable is in a slightly tensioned state. If the jog button is not triggered or the sensor registers a signal, and the current of the repeater box's drive motor exceeds the limit, the cable is in an over-tensioned state.

[0053] The cable stress state is determined by monitoring the current of the relay box's drive motor. If the current is normal, the cable is under minimal stress and is in a slightly tensioned state. If the current exceeds the limit (e.g., 30% above normal), an alarm is triggered, and the relay box's drive motor's winding and unwinding speed is automatically adjusted to reduce the cable tension. This ensures that the wire rope acts as the primary load-bearing carrier, leading the winding and unwinding function, while the relay box acts as a follow-up system, with the cable experiencing only a small force, preventing the cable stress in the relay box from exceeding the set threshold. Under this principle, the cables are wound and unwound synchronously.

[0054] The possible situations, determination methods, and control methods for the steel wire rope and the repeater box cable are as follows: The running speed V1 of the wire rope is obtained through the counting module of the wire winch, and the tension signal S1 of the wire rope is obtained through the tension detection mechanism of the wire winch. The tension signal S1 is divided into two states: slack and tension. The cable's running speed V2 is obtained through the counting module of the relay box, and the cable's tension signal S2 is obtained through the tension detection mechanism and drive motor of the relay box. The tension signal S2 is divided into three states: slack, slightly tense, and over-limit. When V1=V2, it is determined that the wire rope and the cable are in a synchronized state, and the equipment is in good working condition; When V1≠V2, simultaneously read the tension signals S1 and S2 of the wire rope and the cable; if S1 is in a tensioned state, S2 is in a slightly tensioned state, and V1<V2 (only occurs during the wire release process, i.e., during the probe descent), it indicates that the wire rope speed is less than the repeater cable speed, and the wire rope release speed needs to be increased, i.e., the speed of the wire winch drive motor needs to be increased; if S1 is in a tensioned state, S2 is in a slightly tensioned state, and V1>V2 (only occurs during the wire take-up process, i.e., during the probe rise and retract), it indicates that the wire winch take-up speed is too fast, and the wire rope take-up speed needs to be reduced; When V1≠V2, and S1 and S2 are not simultaneously in a tensioned state and a slightly tensioned state, an alarm signal is sent to the operation terminal; if S1 is in a slack state, the winding and unwinding speed of the wire rope is adjusted to bring the wire rope into a tensioned state; if S1 is in a tensioned state and S2 is in a slack state, the winding and unwinding speed of the cable is controlled until S2 is in a slightly tensioned state, and then V2 is reduced to the same speed as V1; if both S1 and S2 are slack signals, the smart probe touches the bottom.

[0055] When S2 is in an out-of-range state, an alarm is sent to the operation terminal. At the same time, the cable winding and unwinding speed of the relay box drive motor is adjusted to reduce the tension on the cable until the cable is in a slightly taut state.
