Description

Technical Field

[0001] The present invention relates to the field of cable laying, and in particular to an optical cable auxiliary traction device and method. Background Art

[0002] In the field of modern communications and power transmission, optical cables are widely used as an efficient transmission medium for long-distance information and energy transmission. However, the laying process of optical cables, especially in pipelines, often faces many challenges. Traditional optical cable traction devices usually rely on manpower or simple mechanical devices. These devices have low laying efficiency over long distances or in complex environments, and are difficult to adapt to the bends and narrow parts of the pipeline. In addition, the traction devices in the prior art often lack flexibility and cannot be effectively fixed and supported in the pipeline, which makes the optical cable easily damaged during the laying process, affecting the communication quality and system stability.

[0003] In some cases, the traction and direction need to be adjusted frequently during the laying process. The existing devices are difficult to operate accurately due to the lack of intelligent control, which increases the difficulty and risk of construction. In addition, when the pipeline is long or there are multiple bends, it is difficult for the existing devices to ensure the uniform laying of the optical cable, which can easily lead to local over-stretching or bending of the optical cable and wear of the pipeline, affecting its service life and transmission performance.

[0004] The existing technical solutions often only focus on one aspect, such as the existing patents CN115951462B and CN114815113B increase the traction force or improve the fixing method of the optical cable, but lack the comprehensive optimization of the entire laying process. Therefore, how to design a method that can adapt to complex pipeline environments, improve laying efficiency, and ensure the safety of optical cables has become a technical problem that needs to be solved in this field.

[0040] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other without conflict.

[0041] The following detailed description is an exemplary description, which is intended to provide further detailed description of the present invention. Unless otherwise specified, all technical terms used in the present invention have the same meaning as those generally understood by those skilled in the art to which the present application belongs. The terms used in the present invention are only for describing specific embodiments, and are not intended to limit exemplary embodiments according to the present invention.

[0042] like Figure 1-3 As shown, an optical cable auxiliary traction device comprises a first traction part 1 and a detachment part 2; a first through hole 11 is provided in the middle of the first traction part 1 for the cable head to pass through, and a first clamping mechanism 12 is provided in the first through hole 11 for clamping or loosening the cable; a connecting part 3 is provided on the first side of the first traction part 1, and at least two groups of power wheels 13 are provided on the end of the first traction part 1 for driving the traction device to move in the pipeline; a connecting part 3 is provided on the first side of the detachment part 2, and a receiving part 4 is provided on the second side of the detachment part 2 for connecting the connecting part 3; a second through hole 21 is provided in the middle of the detachment part 2 for the cable to slide through; at least two groups of rotating wheels 22 and at least two groups of supporting parts 23 are provided on the end of the detachment part 2, and the rotating wheels 22 are used to rotate and fit the inner wall of the pipeline; the supporting part 23 is used to support the detachment part 2 in the pipeline after the detachment part 2 is detached; there are multiple detachment parts 2, and multiple is represented by at least two, and the connecting parts 3 and receiving parts 4 of multiple detachment parts 2 are connected in sequence, and the receiving part 4 at the end is connected to the connecting part 3 of the first traction part 1. The connecting portion 3 and the receiving portion 4 are connected in sequence, and the receiving portion 4 at the end is connected to the connecting portion 3 of the first traction portion 1 .

[0043] Specifically, the first traction part 1 is designed as a solid box or frame, and the first through hole 11 in the middle is a channel with a precise size, which is adapted to the diameter of the cable head to ensure the stability of the cable during the traction process.

[0044] The first clamping mechanism 12 can be a set of clamping claws driven by a servo motor, which can precisely clamp and release the cable head by precisely controlling the rotation of the motor. The connecting part 3 and the disengaging part 2 can be designed with electromagnets, which can achieve rapid connection and separation through electromagnetic adsorption, and are easy to operate and have a fast response speed. The power wheel 13 can be an independently controlled electric wheel, each wheel is driven by a small motor to achieve precise control of traction and direction.

[0045] The device can also be integrated with a visual system, including high-definition cameras and sensors, to monitor the internal conditions of the pipeline and the cable laying process in real time, ensuring that the cables are laid correctly and avoiding damage.

[0046] It also includes a control system, which can be a centralized microcontroller or computer system, which can realize automatic control of the clamping mechanism, the power wheel 13 and the visual system through preset programs and algorithms.

[0047] The support part 23 can be a set of retractable mechanical arms, and the retraction of the mechanical arms is controlled by a micro servo motor to ensure that the separation part 2 is stably supported in the pipeline. The end of the mechanical arm can be provided with anti-skid feet to ensure stability.

[0048] The device adopts a modular design, and each module (such as the detachment part 2) can be customized according to different pipeline conditions. For example, when the pipeline diameter is large, the size of the detachment part 2 and the strength of the support part 23 can be increased. The power of the traction operation is completely provided by the power wheel 13. The design of the power wheel 13 can adapt to different pipeline surfaces, such as smooth or rough, to ensure the stability of the traction process. The surface of the power wheel 13 can be designed with anti-slip texture or use special materials to increase the friction with the inner wall of the pipeline to prevent slipping.

[0049] The electromagnets of the connecting portion 3 and the separating portion 2 can be designed to have adsorption surfaces with different polarities, so as to achieve rapid connection and separation by changing the direction of the current or switching on and off.

[0050] The visual system can transmit the internal image of the pipeline to the control system in real time, and the operator can remotely monitor and adjust the status of the traction device. The control system can automatically adjust the clamping force and the speed of the power wheel 13 according to the data collected by the visual system and the sensor to adapt to different traction conditions.

[0051] Through the above-mentioned specific implementation methods, the optical cable auxiliary traction device provides an efficient, flexible and adaptable solution to prevent the cable from being damaged by dragging on the ground. In addition, it can also realize accurate monitoring and control of the optical cable laying process by integrating advanced visual systems and intelligent control systems.

[0052] As a preferred example, it also includes a second traction part 5, a third through hole 51 is provided in the middle of the second traction part 5 for the cable to pass through; the third through hole 51 is provided with a second clamping mechanism 52 for clamping or loosening the cable, and a receiving part 4 is provided on the first side of the second traction part 5, and the receiving part 4 is used to connect the connecting parts 3 at the ends of multiple detachment parts 2.

[0053] Specifically, the second traction part 5 is designed as a box or frame structure similar to the first traction part 1 to ensure the coordination and consistency of the overall device. A third through hole 51 is provided in the middle of the second traction part 5. The through hole is similar to the first through hole 11 of the first traction part 1 and is also used for passing the cable to ensure smooth transmission of the cable at the second traction part 5. A second clamping mechanism 52 is provided in the third through hole 51. The mechanism can adopt the same technical solution as the first clamping mechanism 12, such as a clamping claw driven by a servo motor, to achieve accurate clamping and loosening of the cable.

[0054] The first side of the second traction part 5 is provided with a receiving part 4, which is designed to receive and connect the connecting parts 3 at the ends of the multiple detachment parts 2, and can adopt the same quick connection mechanism as the connecting part 3 of the first traction part 1, such as electromagnet adsorption or other mechanical locking mechanisms. The second traction part 5 can be operated independently of the first traction part 1, or work in conjunction with the first traction part 1 to achieve the traction and laying of cables from both ends of the pipeline. The second clamping mechanism 52 can include a mechanical clamping system consisting of a gear and a rack, which is driven by a motor to rotate the gear, thereby controlling the movement of the rack to achieve the opening and closing of the clamping claws. The receiving part 4 can be designed as a mechanical structure with a locking groove. When the connecting part 3 of the detachment part 2 is aligned and inserted into the locking groove, a quick connection is achieved through mechanical locking or electromagnetic adsorption.

[0055] The second traction part 5 can be equipped with an independent control system, which works in conjunction with the control system of the first traction part 1 to achieve synchronous control of the entire device. The second traction part 5 can be integrated with a visual system, including a camera and a sensor, for monitoring the laying of the cable at the second traction part 5.

[0056] The second traction unit 5 can be expanded to include additional power wheels 13, support wheels or other auxiliary facilities according to actual needs to adapt to different pipeline conditions and laying requirements. The second traction unit 5 can be designed as a detachable or foldable structure to facilitate rapid replacement or adjustment in different pipeline sections or different laying tasks. The second traction unit 5 can be integrated with an emergency stop button and an overload protection mechanism to ensure that the power supply can be quickly cut off in abnormal situations to prevent cable damage.

[0057] The second traction part 5 not only enhances the function of the optical cable auxiliary traction device and provides the possibility of traction and recovery from both ends of the pipeline, but also improves the flexibility and adaptability of the entire device through coordinated operation with the first traction part 1.

[0058] As a preferred example, a power wheel 13 is provided at the end of the second traction part 5 .

[0059] Specifically, the end of the second traction part 5 is provided with a power wheel 13, and the design and configuration of these power wheels 13 are similar to the power wheels 13 at the end of the first traction part 1 to ensure the consistency of traction and the stable movement of the device in the pipeline. The power wheel 13 provides the necessary mobility for the second traction part 5, so that the second traction part 5 can move autonomously in the pipeline, or work in conjunction with the first traction part 1 to jointly achieve the traction and laying of the cable. The power wheel 13 can be a solid rubber wheel, a metal wheel with an anti-slip texture, or a synthetic material wheel with a special coating to increase friction, and these designs can be selected according to the material and surface characteristics of the pipeline. The power wheel 13 can be directly driven by the motor inside the second traction part 5, or connected to the drive source through gears, belts or other mechanical transmission mechanisms. The layout of the power wheel 13 at the end of the second traction part 5 can be a single wheel, a double wheel or a multi-wheel configuration, which is optimized according to the diameter and shape of the pipeline to achieve the best traction effect. The size and shape of the power wheel 13 can be adjusted according to the inner diameter of the pipeline and the expected load to ensure sufficient contact area and traction. The power wheel 13 can be installed at the end of the second traction part 5 by bolt fixing, snap connection or other quick installation mechanism, which is convenient for maintenance and replacement. The second traction part 5 can be equipped with an independent control system for controlling the speed and direction of the power wheel 13 to achieve precise traction control. The integrated design of the power wheel 13 takes into account the overall coordination with the second traction part 5 to ensure the stability and reliability of the power wheel 13 during operation. The power wheel 13 can be equipped with sensors, such as position sensors or load sensors, to monitor the dynamic information during the traction process in real time, and feed the data back to the control system for adjustment.

[0060] The power wheel 13 is designed with safety in mind, including an emergency stop function and an overload protection mechanism to prevent damage to cables or pipes in abnormal situations.

[0061] The power wheel 13 at the end of the second traction part 5 not only enhances the function of the optical cable auxiliary traction device and provides the possibility of traction and recovery from both ends of the pipeline, but also improves the flexibility and adaptability of the entire device through precise control.

[0062] As a preferred example, the ends of the first traction part 1 and the second traction part 5 are respectively provided with fixing mechanisms for fixing the first traction part 1 or the second traction part 5 in the pipeline when needed.

[0063] Specifically, the ends of the first traction part 1 and the second traction part 5 are respectively provided with fixing mechanisms, which are designed to fix the traction parts in the pipeline under certain circumstances to stabilize the device or prevent it from sliding in the pipeline. The fixing mechanism can provide additional stability during the traction operation, or keep the position of the device in the pipeline when the device needs to be maintained or adjusted.

[0064] The fixing mechanism may include but is not limited to the following forms: a retractable anchor hook designed to hook onto the inner wall of the pipe or a raised portion inside the pipe; an expandable mechanical claw that expands the claw to fit the inner wall of the pipe through hydraulic or pneumatic pressure; a magnetic adsorption device that uses strong magnets to adsorb on metal pipes; a vacuum adsorption cup that adsorbs on the smooth inner wall of the pipe by forming a vacuum. Operation of the fixing mechanism: The fixing mechanism can be operated by manual control, motor drive or pneumatic / hydraulic system to achieve rapid fixing and release.

[0065] The fixing mechanism can be connected to the control system of the traction unit to achieve remote control and automated operation. The fixing mechanism is designed with safety mechanisms, such as automatic locking in the event of power loss, to prevent the device from sliding or shifting. The fixing mechanism design takes into account the adaptability of different pipeline materials and diameters to ensure stable fixing effects in a variety of pipeline environments. The fixing mechanism is integrated with the end of the traction unit, which does not increase the overall size of the device while ensuring ease of operation. The fixing mechanism can be equipped with sensors to monitor the fixing status and feedback to the control system to ensure the accuracy of the fixing operation. The fixing mechanism provides a reliable fixing solution for the optical cable auxiliary traction device, ensuring the stability and safety of the traction operation.

[0066] As a preferred example, the power wheel 13 is connected to the first traction part 1 via a telescopic buffer mechanism 14 .

[0067] Specifically, the connection between the power wheel 13 and the first traction part 1 is realized by a telescopic buffer mechanism 14, which allows the power wheel 13 to perform axial or radial telescopic movement according to the actual conditions of the pipeline. The mechanism is designed to absorb the impact force caused by the bending or unevenness of the pipeline, while providing adaptive contact between the power wheel 13 and the inner wall of the pipeline.

[0068] The telescopic buffer mechanism 14 may include one or more of the following implementations:

[0069] The spring-loaded telescopic arm realizes the buffering and telescoping of the power wheel 13 through the elastic deformation of the spring;

[0070] The hydraulic or pneumatic cylinder drives the extension and retraction through fluid pressure to achieve smooth movement of the power wheel 13;

[0071] A retractable chain or belt connects the power wheel 13 and the first traction part 1, allowing the power wheel 13 to move within a certain range.

[0072] The power wheel 13 can be connected to the first traction part 1 through any form of the telescopic buffer mechanism 14, ensuring that the power wheel 13 can flexibly adapt to the geometric changes of the pipeline. The telescopic buffer mechanism 14 can be controlled by an independent control system, which automatically adjusts the position of the power wheel 13 according to the feedback signal from the sensor inside the pipeline. The telescopic buffer mechanism 14 is designed to be adjustable to adapt to pipelines of different diameters and shapes, ensuring the effective operation of the traction device in various pipeline environments.

[0073] The telescopic buffer mechanism 14 can be integrated with sensors to monitor the position of the power wheel 13 and the pressure in the pipeline, and feed the data back to the control system. The telescopic buffer mechanism 14 not only provides a buffering function, but can also be used for fine-tuning the power wheel 13 to adapt to slight changes in the inner wall of the pipeline.

[0074] The telescopic buffer mechanism 14 provides a flexible and adaptable connection solution for the optical cable auxiliary traction device, ensuring the effective operation of the traction device and the smooth transmission of traction force in a complex pipeline environment.

[0075] As a preferred example, the ends of the first traction part 1 and the second traction part 5 are respectively connected to the fixing mechanism through a telescopic mechanism.

[0076] Specifically, the ends of the first traction part 1 and the second traction part 5 are connected to the fixing mechanism through respective telescopic mechanisms, which allow the fixing mechanism to be telescopically adjusted according to the actual conditions of the pipeline. The telescopic mechanism is designed to achieve axial or radial telescopic expansion of the fixing mechanism to adapt to pipelines of different lengths or shapes, and ensure that the fixing mechanism can stably fix the traction part.

[0077] The telescopic mechanism may include one or more of the following implementations:

[0078] Screw jack structure, which realizes linear extension and retraction of the fixing mechanism by rotating the screw rod;

[0079] Telescopic sleeve structure, the length of the fixing mechanism is adjusted by relative movement of the telescopic sleeve;

[0080] The connecting rod mechanism realizes the extension and retraction of the fixed mechanism by bending or stretching the connecting rod.

[0081] The telescopic mechanism can be connected to the end of the traction unit by mechanical connection methods such as bolts, pins or quick connectors. The telescopic mechanism can be automatically controlled by motors, hydraulic or pneumatic systems to adapt to different operating environments and needs. The telescopic mechanism is designed to be adjustable to adapt to pipes of different diameters and shapes to ensure effective fixation of the traction unit in various pipeline environments. The telescopic mechanism can be integrated with displacement sensors or force sensors to monitor the telescopic state of the fixing mechanism and the pressure in the pipeline, and feed the data back to the control system.

[0082] The telescopic mechanism can not only be used to extend and retract the fixed mechanism, but also can be used to fine-tune the position of the fixed mechanism to adapt to slight changes in the inner wall of the pipeline.

[0083] The telescopic mechanism provides a flexible and adaptable connection solution for the optical cable auxiliary pulling device, ensuring the effective fixation and stable operation of the pulling device in complex pipeline environments.

[0084] An optical cable auxiliary pulling method comprises the following steps:

[0085] S1. Calculate the number of required detachment parts 2 according to the required distance through the pipeline, and connect the calculated number of detachment parts 2 and the first traction part 1 in sequence;

[0086] Specifically, the number of required detachable parts 2 is calculated according to the actual length of the pipeline and the expected laying path. Each detachable part 2 is sequentially connected to the first traction part 1 by the connecting part 3 to form a traction chain with adjustable length. The connection operation can be achieved by means of snap fastening or electromagnetic adsorption to ensure the stability and rapidity of the connection.

[0087] S2, the cable head passes through the calculated number of second through holes 21 of the disengagement part 2 in sequence, and then passes through the first through hole 11 of the first traction part 1, and the cable head is clamped by the first clamping mechanism 12;

[0088] Specifically, the cable head first passes through the second through hole 21 of all the disengagement parts 2, and then passes through the first through hole 11 of the first traction part 1. The cable head is clamped by the first clamping mechanism 12, and the clamping force can be controlled by a motor or adjusted manually to adapt to the diameter and material of the cable to ensure that the cable will not slip or be damaged during the traction process.

[0089] S3, placing the separation part 2 and the first traction part 1 at the starting end in the pipeline;

[0090] Specifically, the connected separation part 2 and the first pulling part 1 are placed as a whole at the starting end of the pipeline. During the placement process, the position and state of the device can be monitored by a visual system to ensure that the device is correctly positioned.

[0091] S4, the power wheel 13 of the first traction part 1 drives the separation part 2 and the first traction part 1 to move toward the end point of the pipeline;

[0092] Specifically, the power system of the first traction unit 1 is started, and the power wheel 13 starts to rotate and drives the entire traction chain to move toward the end of the pipeline. The speed and traction of the power wheel 13 can be adjusted by the control system to adapt to the curvature and friction coefficient of the pipeline.

[0093] S5, when moving to a set distance, disconnecting the connecting portion 3 of a disengaging portion 2 away from the first traction portion 1 from the receiving portion 4 of the adjacent disengaging portion 2;

[0094] Specifically, when the traction chain moves to a set distance, or reaches a certain marked position of the pipeline, the control system issues a command to disconnect the connecting portion 3 of a detaching portion 2 away from the first traction portion 1 from the receiving portion 4 of the adjacent detaching portion 2. The disconnection operation can be achieved by electromagnetic release, mechanical unlocking or pneumatic operation.

[0095] S6, the detached detaching part 2 is supported in the pipeline by the supporting part 23;

[0096] Specifically, after being disconnected, the detachable part 2 is supported in the pipeline by its supporting part 23 , and the supporting part 23 can automatically adjust the supporting force according to the material and shape of the pipeline to ensure that the detachable part 2 is stably fixed in the pipeline.

[0097] S7. Sequentially disengage from the disengagement portion 2 away from the first traction portion 1 every time a set distance is passed, until the first traction portion 1 reaches the end point of the pipeline.

[0098] Specifically, the power wheel 13 of the first traction part 1 continues to drive the remaining traction chains forward, and each time a set distance is passed, steps S5 and S6 are repeated to sequentially detach each detachment part 2 and support it in the pipeline until the first traction part 1 reaches the end of the pipeline.

[0099] During the entire traction process, the control system monitors the traction speed, cable tension and device status in real time to ensure the safety and efficiency of the traction operation. In addition, the visual system provides real-time images of the inside of the pipeline to help the operator control the traction process more accurately.

[0100] The optical cable auxiliary pulling method provides an efficient, flexible and adaptable optical cable laying solution, which is suitable for pipeline optical cable laying operations of different lengths and complexities.

[0101] As a preferred example, in step S1, the second traction part 5, the calculated number of separation parts 2 and the first traction part 1 are connected in sequence;

[0102] Specifically, based on calculating the number of required detachment parts 2 and sequentially connecting them to the first traction part 1, this step further includes connecting the second traction part 5 to the first traction part 1. Specifically, the second traction part 5 is sequentially connected to the connection parts 3 at the ends of the plurality of detachment parts 2 through its receiving part to form a complete traction system. This connection operation can be achieved through a quick connection mechanism, such as electromagnetic adsorption or mechanical locking, to ensure the stability of the connection and the convenience of subsequent operations.

[0103] In step S2, before the cable head sequentially passes through the calculated number of second through holes 21 of the separation portion 2, the step also includes: the cable head passes through the third through hole 51 of the second traction portion 5;

[0104] Specifically, after the cable head passes through the second through holes 21 of all the separation parts 2, the cable head needs to pass through the third through hole 51 of the second traction part 5. This step ensures the continuity of the cable in the entire traction system, and the cable can be pulled and laid through the second traction part 5. The cable head passing through the third through hole 51 is also clamped by the second clamping mechanism 52 of the second traction part 5 to ensure the stability of the cable during the traction process.

[0105] Step S3 also includes fixing the second traction part 5 at the starting end in the pipeline by a fixing mechanism.

[0106] Specifically, on the basis of placing the separation part 2 and the first traction part 1 at the starting end in the pipeline, this step further includes fixing the second traction part 5 at the starting end in the pipeline using a fixing mechanism. The operation of the fixing mechanism can be realized by manual or automatic control, such as controlling the telescopic mechanism by a hydraulic or pneumatic system, or fixing the anchor hook or adsorption device by mechanical tightening. The fixing mechanism ensures that the position of the second traction part 5 is stable during the traction process to prevent it from moving or rotating in the pipeline.

[0107] During the implementation of the entire traction method, the control system can be used to monitor and adjust each step to ensure the stability of the traction process and the safety of the cable. For example, the control system can adjust the clamping force of the clamping mechanism according to the actual situation of the pipeline, or adjust the speed of the power wheel 13 according to the feedback of the traction force.

[0108] In addition, the vision system can assist the operator in real-time monitoring of the status of cables and traction devices, ensuring that the cables are not damaged when passing through various through holes and pipes, and that the traction devices are properly fixed in the pipes.

[0109] The optical cable auxiliary traction method provides a capability of laying cables from both ends of a pipeline, increases the flexibility of operation, and improves the stability and safety of the traction process through the application of a fixing mechanism.

[0110] As a preferred example, the method further includes the following steps:

[0111] When the first traction part 1 reaches the end of the pipeline, the first clamping mechanism 12 of the first traction part 1 is opened, and the first traction part 1 moves along the pipeline and the cable from the end of the pipeline to the starting end in the pipeline;

[0112] When the first pulling part 1 contacts the detaching part 2, the connecting part 3 of the first pulling part 1 is connected with the receiving part 4 of the detaching part 2, and the supporting part 23 of the detaching part 2 is released;

[0113] The first traction part 1 drives the disengagement part 2 to continue to move, connects all the disengagement parts 2 in sequence, and returns to the starting end in the pipeline.

[0114] Specifically, the following steps are included:

[0115] Before starting the recovery process, the control system is operated to send a command to the first traction part 1 , and the command is used to control the first clamping mechanism 12 to perform an opening action, thereby releasing the cable head and preparing for the recovery of the disengagement part 2 .

[0116] After the first clamping mechanism 12 is opened, the first traction part 1 starts to move along the pipeline and the cable toward the starting end in the pipeline. This movement can be achieved by the power system of the first traction part 1, which provides appropriate traction force and speed as required.

[0117] When the first traction part 1 moves and contacts the detachment part 2 in the pipeline, the connection part 3 of the first traction part 1 is connected with the receiving part 4 of the detachment part 2. This connection can be achieved by a pre-set quick connection mechanism, such as electromagnetic adsorption or mechanical locking, to ensure the stability of the connection and the convenience of operation.

[0118] Once the first traction part 1 is connected to the detachment part 2, the support part 23 of the detachment part 2 receives a signal or releases the support through a mechanical trigger mechanism, thereby allowing the detachment part 2 to detach from the inner wall of the pipeline and reduce friction with the pipeline.

[0119] The first traction part 1 continues to move along the pipeline, driving the connected detaching part 2. As the first traction part 1 moves forward, it is connected with the remaining detaching parts 2 in sequence until all detaching parts 2 are connected and driven to the starting end in the pipeline.

[0120] During the recovery process, the control system monitors the pulling speed, cable tension and device status in real time to ensure the safety and efficiency of the pulling operation. The visual system provides real-time images of the inside of the pipeline to help the operator control the pulling process more accurately.

[0121] After reaching the starting end in the pipeline, all the disengaging parts 2 driven by the first traction part 1 will be safely stored or proceed to the next operation, completing the entire recycling process.

[0122] The optical cable auxiliary traction method provides an efficient and orderly cable and detachment part 2 recovery solution, which is suitable for quickly recovering the traction device after the pipeline laying operation is completed, reducing operation time and labor intensity.

[0123] As a preferred example, the method further includes the following steps:

[0124] When the first traction part 1 reaches the end point of the pipeline, the second traction part 5 moves along the pipeline and the cable from the starting end in the pipeline to the end point of the pipeline;

[0125] When the second traction portion 5 contacts the detachment portion 2, the receiving portion 4 of the second traction portion 5 is connected to the connecting portion 3 of the detachment portion 2, and the supporting portion 23 of the detachment portion 2 is released from support;

[0126] The second traction part 5 drives the detaching part 2 to continue to move, connects all the detaching parts 2 in sequence, and reaches the end of the pipeline to connect with the first traction part 1.

[0127] Specifically, the following steps are included:

[0128] After the first traction part 1 successfully reaches the end of the pipeline and completes its function, the operation of the second traction part 5 is started. At this time, the second traction part 5 is located at the starting end of the pipeline, ready to start the process of recovering the separation part 2.

[0129] The second traction part 5 moves along the pipeline and the cable toward the pipeline end. This movement operation can be achieved by the built-in power system of the second traction part 5, which provides appropriate traction according to the pipeline condition and the cable state.

[0130] When the second traction part 5 moves and contacts the detachment part 2 in the pipeline, the receiving part 4 of the second traction part 5 is connected with the connecting part 3 of the detachment part 2. This connection can be achieved by a preset quick connection mechanism, such as electromagnetic adsorption or mechanical locking, to ensure the stability of the connection and the convenience of operation.

[0131] Once the second traction part 5 is connected to the detachment part 2, the support part 23 of the detachment part 2 receives a signal or releases the support through a mechanical trigger mechanism. This allows the detachment part 2 to detach from the inner wall of the pipe, reducing friction and resistance during the recovery process.

[0132] The second traction part 5 continues to move along the pipeline, driving the connected detaching part 2. As the second traction part 5 moves forward, it is connected with the remaining detaching parts 2 in sequence until all detaching parts 2 are connected and driven to the end of the pipeline.

[0133] When the second traction part 5 drives the disengagement part 2 to move, the control system monitors the traction speed, cable tension and device status in real time to ensure the safety and efficiency of the traction operation. The visual system provides real-time images of the inside of the pipeline to help the operator control the traction process more accurately.

[0134] When the second traction part 5 reaches the end of the pipeline and connects with the first traction part 1, the recovery of all the detached parts 2 is completed. At this time, the entire traction device and the cable are safely recovered to the starting end or the end end of the pipeline, completing the entire optical cable laying and recovery operation.

[0135] The optical cable auxiliary traction method provides a capability of laying and recovering cables from both ends of a pipeline, increases the flexibility of operation, and improves the stability and safety of the traction process through the application of a fixing mechanism.
