Description

Technical Field

[0001] This invention relates to the field of cable winding device technology, and specifically to a cable winding device for dismantling underground cables. Background Technology

[0002] Downhole cable dismantling refers to the safe and orderly removal of laid power supply, communication, or data transmission cables from their working location in confined spaces such as underground mines and oilfield drilling sites. This process typically involves equipment maintenance, workface relocation, or cable replacement. After dismantling, cables usually need to be recycled for reuse or proper disposal to reduce production costs, minimize resource waste, and ensure a clean and safe underground environment. Cable recycling and winding are critical processes in downhole cable dismantling operations, as their quality directly affects the cable's subsequent performance and lifespan. Traditional winding devices often use a fixed tension winding method, which is difficult to dynamically adjust according to changes in cable diameter, easily leading to the following problems: In the initial winding stage, excessive tension can cause insulation layer compression deformation and armor layer damage; in the middle and later stages of winding, insufficient tension can lead to loose cable layers and uneven arrangement, making them prone to friction, scratches, and even structural damage during transportation and storage.

This design effectively solves the core problem of the traditional winding device having fixed tension and being unable to adapt to changes in roll diameter. It realizes the basic adjustment function of increasing winding tension as the roll diameter increases, thereby avoiding the drawbacks of damaging the cable due to excessive tension in the early stage of winding and causing the roll layer to loosen due to insufficient tension in the middle and later stages. Secondly, by integrating tension sensors, controllers, and solenoid valves, the actual tension on the cable can be monitored in real time and compared with the preset optimal tension value that meets the protection requirements of each winding stage (initial, middle, and late stages). The controller intelligently controls the opening of the solenoid valve to adjust the driving air pressure, ultimately maintaining a dynamic balance of pressure on the cable from the transmission rollers, thus achieving precise and adaptive adjustment of winding tension at different winding stages.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0017] The present invention will be further described below with reference to embodiments.

[0018] Example: Refer to Figures 1 to 6 A cable reeling device for dismantling underground cables, comprising: Fixed frame 1; The winding assembly 2 includes a spool 204 disposed within the fixed frame 1, the spool 204 being used to wind the cable; The cable management component 3 includes a retaining ring 305, which is driven to reciprocate within the fixed frame 1 to guide the cable to swing back and forth. The cleaning guide assembly 4 includes a support plate 402. A linkage plate 406 is symmetrically and elastically installed at the lower end of the support plate 402. An arc-shaped slot 407 is provided on the opposite side of the linkage plate 406. The linkage plate 406 clamps the cable through the arc-shaped slot 407. A second external frame 409 is provided below the linkage plate 406. A brush 410 for cleaning the outer wall of the cable is fixedly installed inside the second external frame 409. During operation, the cable to be recycled is passed through the center of the brush 410 of the cleaning guide assembly 4, the arc-shaped slot 407 formed by the linkage plate 406, below the transmission roller 505 of the tension adjustment assembly 5, and the retaining ring 305 of the cable management assembly 3 in sequence, and finally its end is fixed on the reel 204. The tension adjustment component 5 includes a bracket 503 rotatably disposed between the support plate 402 and the retaining ring 305. A U-shaped connector 504 is fixedly installed at the lower end of the bracket 503. A transmission roller 505 is rotatably installed inside the U-shaped connector 504. The bracket 503 is driven to rotate, which drives the transmission roller 505 to squeeze the cable and adjust the cable tension.

[0019] A retaining ring 201 is symmetrically installed on the inner wall of the fixed frame 1. A retaining block 202 is slidably installed on the outer wall of the retaining ring 201. A screw 203 is threaded onto the outer wall of the retaining block 202. A scroll 204 is slidably connected to the inner wall of the retaining ring 201. A rotary drive component 205 is fixedly installed on one side of the fixed frame 1. The rotary drive component 205 uses an existing 80DK-M07725 servo motor. Its output end is directly fixedly connected to the retaining ring 201. Its core function is to drive the retaining ring 201 to rotate, thereby driving... The slidably connected reel 204 rotates synchronously, thus providing power for the continuous and stable winding of the cable. The output end of the rotary drive 205 passes through the fixed frame 1 and is fixedly connected to the retaining ring 201. When the rotary drive 205 is started, the retaining ring 201 and the reel 204 are driven to rotate, and the cable is started to be wound. When the cable moves, its surface is automatically cleaned by the brush 410. At the same time, the elastically supported linkage plate 406 clamps the cable and also plays a guiding role, ensuring that the cable is always aligned with the cleaning and adjustment part.

[0020] A rotating head 301 is symmetrically fixedly installed on the inner wall of the fixed frame 1 between the support plate 402 and the reel 204. A transmission rod 302 is fixedly installed between the retaining rings 201. The outer wall of the transmission rod 302 has a reciprocating threaded groove 303. A transmission sleeve 304 is fitted on the outer wall of the transmission rod 302. A fixed ball is embedded in the transmission sleeve 304. The transmission sleeve 304 is threadedly connected to the reciprocating threaded groove 303 through the fixed ball. The outer wall of the transmission sleeve 304 is fixedly connected to the retaining ring 305. The inner wall of the retaining ring 305 has a friction groove 306. The friction force when the cable is wound up drives the retaining ring 305 to rotate. The retaining ring 305 cooperates with the transmission rod 302 with the reciprocating threaded groove 303 through the transmission sleeve 304 to convert the rotational motion into its own axial reciprocating movement. This allows the cable to be guided to be evenly distributed back and forth on the reel 204, achieving neat winding.

[0021] An external plate 401 is fixedly installed on one side of the fixed frame 1. The external plate 401 is fixedly connected to the support plate 402 near the roller 204. A first external frame 403 is fixedly installed on both sides of the support plate 402. A clamping plate 404 is slidably installed on the inner wall of the first external frame 403. A first spring 405 is fixedly installed between the clamping plate 404 and the first external frame 403. The lower end face of the clamping plate 404 is fixedly connected to the linkage plate 406.

[0022] A mounting plate 408 is fixedly installed on one side of the support plate 402, and the side of the mounting plate 408 near the outer plate 401 is fixedly connected to the second outer frame 409.

[0023] An outer plate 401 has a rotating groove 501, and a first rotating rod 502 is fixedly installed in the rotating groove 501. The outer wall of the first rotating rod 502 is rotatably connected to the bracket 503. A square frame 506 is fixedly installed at the upper end of the bracket 503, and a second rotating rod 507 is fixedly installed inside the square frame 506. A fixing box 511 is fixedly installed on the upper surface of the outer plate 401, and a first sleeve 512 is fixedly installed inside the fixing box 511. A second sleeve 512 is slidably installed on the inner wall of the first sleeve 512. 13. A third spring 514 is fixedly installed between the second set of barrels 513 and the first set of barrels 512. A straight rod 515 is fixedly installed on the inner wall of the second set of barrels 513. One end of the straight rod 515 passes through the first set of barrels 512 and is fixedly installed with a rotating connector 516. The rotating connector 516 is rotatably connected to the second rotating rod 507. A solenoid valve 517 is embedded in the fixed box 511. The solenoid valve 517 is an existing device installed in the fixed box 511. Its core function is to: respond to the instructions issued by the controller. The controller precisely controls the air pressure level in the first set of barrels 512 by changing the opening of its valve core. Specifically, when the tension sensor 509 detects that the actual tension is higher than the preset optimal tension value for the current winding stage, the controller will instruct the solenoid valve 517 to increase its opening to discharge some gas, thereby reducing the driving air pressure and reducing the clamping force of the transmission roller 505 on the cable, causing the tension to drop. Conversely, when insufficient tension is detected, the controller instructs the solenoid valve 517 to decrease its opening or even close it, allowing the airbag 523 to continuously deliver gas to maintain or increase the air pressure, thereby enhancing the clamping effect of the transmission roller 505 and increasing the tension. The solenoid valve 517 is electrically connected to the controller, which uses an existing PLC and basic control algorithms such as PID control and threshold comparison switch control. Based on the winding time, the number of revolutions fed back by the encoder of the rotating drive 205, or the pre-input total cable length information, the controller roughly divides the winding into the initial, middle, and late stages and calls the preset tension threshold range corresponding to the stage.

[0024] A horizontal plate 518 is fixedly installed on the upper surface of the fixed frame 1. A round rod 519 is symmetrically slidably installed inside the horizontal plate 518. An arc-shaped cover 521 is fixedly installed at the lower end of the round rod 519. A fourth spring 520 is fixedly installed between the arc-shaped cover 521 and the horizontal plate 518, and on the outer wall of the round rod 519. A square plate 522 is fixedly installed inside the horizontal plate 518. An airbag 523 is fixedly installed between the square plate 522 and the arc-shaped cover 521. A flexible hose 524 is connected to the upper end of the airbag 523. One end of the flexible hose 524 passes through the square plate 522 and connects to the fixed box 511. As winding proceeds, the cable layer accumulates on the reel 204. As the diameter gradually increases, the increased diameter pushes up the upper arc-shaped cover 521, which compresses the airbag 523. The air inside the airbag 523 is forced into the first set of barrels 512 inside the fixed box 511 through the hose 524, causing the internal air pressure to rise. The air pressure pushes the second set of barrels 513 to slide outward against the elastic force of the third spring 514, and then pushes the square frame 506 through the straight rod 515 and the rotating connector 516. The square frame 506 drives the bracket 503 to rotate around the first rotating rod 502, so that the transmission roller 505 installed at the lower end of the bracket 503 presses against the cable, thereby initially increasing the winding tension of the cable.

[0025] A vertical plate 508 is fixedly installed on the lower end face of the outer plate 401. A tension sensor 509 is fixedly installed on one side of the vertical plate 508. The tension sensor 509 is an existing device, vertically installed on the vertical plate 508 at the lower end of the outer plate 401, and flexibly connected to the bracket 503 through a second spring 510. Its core function is to convert the mechanical deformation force applied to the second spring 510 due to the rotation of the bracket 503 during the cable winding process into a corresponding continuous electrical signal output in real time and accurately. This electrical signal directly reflects the real-time pressure applied to the cable by the drive roller 505, that is, the actual winding tension of the cable. The controller continuously receives this signal and compares it with the preset maximum values ​​for different winding stages (initial, middle, and late stages). The optimal tension threshold is compared, thus providing a key decision basis for the controller to intelligently adjust the opening of the solenoid valve 517 and dynamically correct the clamping force of the transmission roller 505. The tension sensor 509 is electrically connected to the controller. A second spring 510 is fixedly installed between the output end of the tension sensor 509 and the bracket 503. However, open-loop adjustment based solely on the change in winding diameter may not be able to accurately match the subtle tension requirements of different cables or different winding stages. Therefore, the device introduces a closed-loop feedback system. The rotation of the bracket 503 will stretch or relax the second spring 510 connected to it. The deformation force of the second spring 510 acts on the tension sensor 509. The tension sensor 509 converts the detected tension signal into an electrical signal and transmits it to the controller in real time. The controller has preset optimal tension value curves or ranges for different stages such as the initial, middle, and final winding stages. It compares the received real-time tension signal with the preset value. If the real-time tension is higher than the ideal value required for the current roll diameter stage (such as the initial winding stage), the controller sends a command to the solenoid valve 517 to open it appropriately, expelling some of the gas in the first set of drums 512 and reducing the internal air pressure. After the air pressure decreases, the pressure of the drive roller 505 on the cable is reduced under the adjustment of the rebound force of the third spring 514, thereby causing the tension to fall back to the preset range. Conversely, if insufficient tension is detected (such as when a larger tension is required in the middle winding stage), the controller reduces the opening of the solenoid valve 517 or even closes it, allowing the airbag 523 to continuously deliver gas to increase the pressure in the first set of drums 512, thereby pushing the drive roller 505 to increase the pressure on the cable and increase the tension. This feedback adjustment process is continuously and dynamically carried out to ensure that the cable tension can intelligently adapt to changes in roll diameter and remain stable in the optimal range throughout the entire winding process.

[0026] The working principle of this invention is as follows: By passing the cable through the brush 410, support plate 402, U-shaped connector 504, and retaining ring 305, one end of the cable is fixed to the outer wall of the reel 204. The outer wall of the cable will contact the brush 410, which will clean the dirt adhering to the outer wall of the cable as the cable moves. Furthermore, as the cable passes through the inner wall of the support plate 402, the linkage plate 406 will cause the retaining plate 404 to slide along the inner wall of the first outer frame 403 and compress the first spring 405. The first spring 405 will apply a counterforce to move the retaining plate 404 and the linkage plate 305. The movable plate 406 clamps and fixes the cable. It should be noted that the inner wall of the arc-shaped bayonet 407 is made of rubber, which has a certain elasticity when clamping the cable, protecting the cable from damage during movement. At the same time, the movable plate 406 can keep the outer wall of the cable fixed in the middle of the inner wall of the brush 410 during the clamping process, so that the brush 410 can evenly clean the dirt attached to the outer wall of the cable, and prevent the dirt from squeezing and damaging the cable when it is wound around the outer wall of the reel 204. Pull the locking block 202 upward within the retaining ring 201 beforehand. Tilt the spool 204 and place it inside the retaining ring 201, aligning it with the axis of the retaining ring 201. Press the locking block 202 to slide within the retaining ring 201. Rotate the screw 203 to engage with the spool 204, fixing the locking block 202 within the retaining ring 201 and making it fit against the outer wall of the spool 204. By opening the rotary drive component 205, drive the spool 204 to rotate, winding the cable. The outer wall of the cable will contact the inner wall of the retaining ring 305 below the transmission rod 302. The friction groove 306 increases the friction with the cable, causing the retaining ring 305 and the transmission sleeve 304 to rotate on the outer wall of the transmission rod 302 during winding. This allows the fixed ball to roll against the reciprocating thread groove 303, driving the transmission sleeve 304 and the retaining ring 305 to reciprocate on the outer wall of the transmission rod 302, ensuring the cable is evenly wound on the outer wall of the spool 204. It should be noted that when the cable is wound on the outer wall of the reel 204, the tension of the cable needs to be adjusted according to the cable reel diameter. If the tension is not adjusted according to the cable reel diameter, excessive high tension throughout the winding process will cause cable deformation, cracks in the insulation layer, and dents in the armor layer. Furthermore, under high voltage, the cable sheath will be excessively stretched, and the interlayer friction and heat generation will be intensified, leading to accelerated aging of the insulation material. This will make the cable unable to be laid normally again (difficult to bend, reduced electrical performance) or insulation breakdown will occur as soon as power is applied. On the other hand, low tension winding throughout the process will cause the cable layers to become loose, cross, and arched, with no tightness. Loose cables will shake and rub violently during transportation, causing large-area scratches on the sheath and even breakage of internal components. Therefore, the tension of the cable needs to be adjusted according to the cable reel diameter when winding the cable. As the cable winds around the outer wall of the reel 204, the diameter gradually increases, causing the cable to contact the arc-shaped cover 521 and drive it to move upward within the fixed frame 1. The moving arc-shaped cover 521 then drives the round rod 519 upward within the horizontal plate 518, compressing the fourth spring 520 (facilitating subsequent reset of the arc-shaped cover 521). Furthermore, the upward-moving arc-shaped cover 521 compresses the airbag 523, causing air inside the airbag 523 to be transported through the hose 524 to the fixed box 511 and the first sleeve 512. This gradually increases the air pressure inside the first sleeve 512, pushing the second sleeve 513 to slide and stretch the third spring 514 inside the first sleeve 512. When the inner wall of 512 slides, it will drive the straight rod 515 and the rotating connector 516 to move. The rotating connector 516 drives the square frame 506, the bracket 503 and the U-shaped connector 504 to rotate around the axis of the second rotating rod 507 through a rotatable connection with the second rotating rod 507. This causes the transmission roller 505 to squeeze the cable. When the cable is driven to wind, the contact point between the outer wall of the cable and the arc-shaped bayonet 407 is the first fixed point, and the contact point between the cable and the outer wall of the roll 204 is the second fixed point. When the transmission roller 505 is driven to contact the cable and squeeze it, the tension of the cable is increased, so that the cable has different tensions when winding at different roll diameters. It should also be noted that, based on the required cable length and the diameter of the reel 204, a preset value for the tension sensor 509 is pre-set. When the bracket 503 is driven to rotate and contact the cable, the rotating bracket 503 stretches the second spring 510. The elastic force of the second spring 510 causes the tension sensor 509 to generate an electrical signal. This causes the tension sensor 509 to generate different electrical signals depending on the rotation angle of the bracket 503. In the initial stage of winding, if the rotation angle of the bracket 503 is too large, causing the tension sensor 509 to generate an electrical signal exceeding the preset value (in the initial stage of cable winding, the cable winding tension should be kept at a low tension, and the cable is initially wound on an empty reel), When the cable is wound on the reel 204, the winding diameter is at its smallest. Applying excessive tension at this point can cause deformation of the insulation layer. During continuous winding, the inner cable experiences enormous radial pressure, which may flatten or damage the internal structure. Therefore, the tension sensor 509 should be preset based on the low tension at the initial stage of winding (as a winding target). The controller will activate the voltage input to the solenoid valve 517 based on the electrical signal generated by the tension sensor 509, causing the valve core of the solenoid valve 517 to open. This allows air inside the first set of drums 512 to escape, reducing air pressure and slowing the sliding of the second set of drums 513 inside the first set of drums 512. This also reduces the contact between the straight rod 515 and the rotating connector 516 driving the bracket 503. The rotation amplitude reduces the squeezing force between the drive roller 505 and the cable, thus reducing the cable tension. However, during the middle stage of winding, the winding force of the cable needs to be increased (to balance the tightness of the cable winding and the cable protection requirements, and to suppress sheath wear caused by interlayer sliding friction). The tension sensor 509 controls the opening of the solenoid valve 517 in real time based on the electrical signal generated by the rotation of the bracket 503 and the stretching of the second spring 510. As the airbag 523 is continuously compressed and air is supplied into the first set of barrels 512 to increase the air pressure, the air pressure inside the first set of barrels 512 is intelligently adjusted, causing the second set of barrels 513 to move. This drives the bracket 503 to drive the drive roller 505 towards the outer plate 401. The direction is rotated and the cable is squeezed to adjust the tension of the cable during winding. In the later stage of winding, it is necessary to reduce the winding tension of the cable between the initial and middle stages (reduce the radial pressure of the outer cable on the inner layer, prevent the inner ring from collapsing, and reduce the risk of interlayer misalignment caused by inertial force). The tension sensor 509 needs to set a preset value based on this preset target. The controller controls the voltage input to the solenoid valve 517 to make the solenoid valve 517 vent, so that the second set of barrels 513 drives the straight rod 515 and the rotating connector 516 to rotate. The rotation amplitude of the drive bracket 503 and the transmission roller 505 is reduced compared with the middle stage of winding to meet the tension winding conditions of the cable during winding.
