Description

Technical Field

[0001] This invention belongs to the field of winch technology, and specifically relates to a cable winch with two take-up modes. Background Technology

[0002] Cable winches are used to collect cables from temporarily installed electrical equipment. These devices often require considerable cable lengths, such as lighting systems in rescue vehicles, power supplies for various rescue equipment, and pipeline robots for detecting underground pipelines. Currently, cable winch tension detection relies on electronic chip components like tension sensors and microcontrollers to control the winch's stop, preventing excessive tension that could cause cable breakage. However, the reliability of electronic components is not as guaranteed as that of mechanical structures, especially since cable winches are often used outdoors, where reliability is severely reduced, particularly in harsh environments.

[0003] On the other hand, since there is often water accumulation outdoors or in pipes, water often adheres to the surface of cables when they are stored. Current cable reels do not have the function of removing water adhering to the outer surface of the cables. If the cables are stored in a roll for a long time, the inner ring will be in a damp state, which will pose a risk of leakage. Summary of the Invention

[0004] In view of the defects of the prior art, the technical problem to be solved by the present invention is to provide a cable winch with two winding modes. The winch adopts a mechanical structure to block and open the device and has the function of removing attached water, and has two optional modes for continuous winding and intermittent winding in combination with water removal.

[0005] The objective of this invention is achieved through the following technical solution: a cable winch with two winding modes, comprising a winding reel for winding and unwinding, a rope guide in front of the winding reel, an active winding device in front of the rope guide, and a blower assembly for removing water adhering to the outer surface of the cable between the rope guide and the active winding device, the blower assembly consisting of a housing and several fans mounted on the upper part of the housing.

[0006] Preferably, a handle frame is provided above the take-up reel; the handle frame consists of handles on both sides and a horizontal connecting plate in the middle, with the handles on both sides connected to the frame on both sides to form a good whole.

[0007] Preferably, the rope guide includes a reciprocating transmission assembly located at the lower part of the horizontal connecting plate, and a rope guide seat plate connected to two frames at both ends respectively; the rope guide seat plate is plate-shaped with an obtuse-angled folded edge, forming two opposing upper and lower areas after the folded edge, a set of track translation assembly is provided above the folded edge, and a long strip-shaped moving guide groove is provided below the folded edge, the cross-section of the moving guide groove is arc-shaped, and a sliding guide member matching the arc shape and capable of sliding closely is provided in the arc-shaped cross-section;

[0008] The sliding guide is fixedly connected to the slider of the track translation assembly via a first connector. The sliding guide has a cylindrical center with a through hole for the cable to pass through. The edges at both ends of the hole have rounded chamfers, and the circumference of the cylinder is provided with several flexible support members. When the cable flows within the through hole, the cylinder can have a certain swing amplitude under the support of the flexible support members to reduce the vibration caused by the cable moving up and down.

[0009] Preferably, the active take-up device includes a dragging motor assembly mounted on the upper part of the horizontal connecting plate, a cable recovery motor mounted on the dragging motor assembly, and a dragging connector whose one end is fixedly connected to a slider in the dragging motor assembly and whose other end is fixedly connected to a lead screw nut in the reciprocating transmission assembly. The dragging connector passes through the horizontal connecting plate, and an elongated opening for the dragging connector to move is provided at a corresponding position on the horizontal connecting plate. Thus, the active take-up device is controlled by the reciprocating transmission assembly to move laterally in sync with the rope guide, so that the take-up reel winding, the active take-up device winding, and the rope guide guiding are all carried out synchronously, forming a protected and orderly take-up.

[0010] Preferably, the active take-up device also includes a combined transmission component for take-up, and an automatic disconnection mechanism triggered when the cable is pulled by a foreign object during take-up, causing the take-up resistance to increase to a limit value; the combined transmission component includes a continuous take-up component and an intermittent take-up component, as well as a take-up mode switching component for switching between the two, and also includes a take-up execution component.

[0011] The continuous cable reel assembly includes a generally H-shaped assembly mounting frame fixedly connected to a slider in the track translation assembly, a movable locking shaft installed in the assembly mounting frame, a first synchronous drive wheel installed in the movable locking shaft, a second synchronous drive wheel fixedly connected to the output shaft of the cable reel motor, and a first synchronous drive belt connecting the first synchronous drive wheel and the second synchronous drive wheel via belt drive.

[0012] The intermittent cable reel assembly includes a one-way drive flywheel mounted in a movable chuck, an eccentric cam fixedly connected to the output shaft of the cable reel motor, and a reciprocating rigid chain belt that connects the one-way drive flywheel and the eccentric cam via a one-way chain drive. The one-way drive flywheel is designed to rotate clockwise for effective rotation and counterclockwise for idle rotation. The reciprocating rigid chain belt is generally long and narrow, with one end being a single-sided slat and the other end being a rectangular frame with three sides. A section of chain belt matching the tooth profile of the one-way drive flywheel is fixed inside the frame. The frame has a long, movable hole on its side relative to the slat. This design, which uses multiple components for both cable reel modes, offers numerous advantages in terms of space, material cost, and ease of use.

[0013] Preferably, the take-up mode switching component includes a lifting rod that is slidably connected to a movable elongated hole at one end, a lifting slide in the component mounting frame, a lifting slider in the lifting slide, and a mode switching knob that is located above the lifting slide and threadedly connected to the lifting slide; the threaded end of the mode switching knob is connected to the lifting slider, and the other end of the lifting rod is connected to the lifting slider.

[0014] The take-up mode switching component also includes a tensioning member disposed in the component mounting frame on the side facing the take-up reel. The tensioning member includes a first tensioning pulley that presses against the first synchronous transmission belt, an adapter arm with one end rotatably connected to the first tensioning pulley and the other end having a roller, and a lifting and loosening part that has a certain clearance fit with the roller of the adapter arm. The middle part of the adapter arm is hinged to the component mounting frame, and an elastic element that presses against the adapter arm is disposed on the side of the hinge point near the first tensioning pulley. This elastic element ensures that the first tensioning pulley always presses against the first synchronous transmission belt and that the roller of the adapter arm contacts the upper part of the lifting and loosening part while leaving a gap at the lower part. This gap provides elastic space for the first tensioning pulley, so that the tension can also change when the belt force changes. Here, the first synchronous transmission belt is in a relaxed state when the first tensioning pulley does not have sufficient pressure.

[0015] Preferably, the component mounting frame has a backrest on the side facing the take-up reel, and the movable retaining shaft is located in front of the backrest.

[0016] The automatic disconnection mechanism includes movable through holes in the two side walls of the component mounting frame and an elastic bearing hinged in the backrest; the movable through holes are used to install the movable retaining shaft, and the hinge point of the elastic bearing must be higher than the axis of the movable retaining shaft.

[0017] The automatic disconnect mechanism also includes a reset assembly in front of the movable card shaft. The reset assembly includes a reset waist hole located on one side wall of the component mounting frame and diagonally below the movable through hole, a reset push block abutting against the inner wall of the component mounting frame, a guide shaft with one end passing through the reset push block and partially exposed, the other end movably installed in the reset waist hole and partially exposed, a reset knob installed in front of the component mounting frame, a fixing block for installing the reset knob, two reset tension springs at both ends of the guide shaft, and a guide plate located below the reset push block and fixed to the inner wall of the component mounting frame. The purpose of this arrangement is that when the automatic disconnect mechanism is in the disconnected state, i.e., the movable card shaft falls below the movable through hole, the reset knob is rotated to reset. The reset knob pushes the reset push block forward against the tension of the two reset tension springs until its inclined surface contacts the movable card shaft. Continuing to rotate the reset push block pushes the movable card shaft forward. At this time, under the guidance of the guide plate and the reset waist hole, the reset push block is tilted upward as a whole, thereby moving the movable card shaft upward until the movable card shaft re-enters the upper part of the movable through hole to complete the reset. Then rotate the reset knob in the opposite direction to return the reset push block to its initial position. It should be noted that if the elastic bearing used has a large elastic force, the reset assembly needs to be further configured on the outer wall of the other side of the assembly mounting frame. This way, the reset action can be performed simultaneously from both sides, making the reset easier to complete.

[0018] In summary, the present invention has the following advantages compared with the prior art:

[0019] This invention features an active take-up device in front of the take-up reel, meaning the take-up is not done directly through the reel. An automatic disconnect mechanism is incorporated within the active take-up device. When foreign objects entangle the cable and create resistance, the automatic disconnect mechanism activates, causing the take-up to fail and thus protecting the cable from damage. Furthermore, the rope guide and the active take-up device are positioned in relatively fixed locations and are controlled by a set of transmission components for reciprocating lateral movement. This synchronized movement of the two devices allows for better take-up of the cable into a coil.

[0020] A blower assembly for removing water adhering to the outer surface of the cable is installed between the cable guide and the active cable reel device. The blower assembly consists of a housing and several fans installed on the upper part of the housing. This allows the cable to be reeled into a relatively sealed housing for air drying. Depending on the amount of water adhering to the outer surface of the cable, the cable reeling mode is designed to be either continuous or intermittent. When there is a lot of water, the intermittent reeling mode is used to increase the time the cable spends air drying in the housing and improve the drying effect. Attached Figure Description

Detailed Implementation

[0032] The present invention will be further described below with reference to the embodiments illustrated in the accompanying drawings:

[0033] Example 1

[0034] like Figures 1-9As shown, a cable winch with two winding modes is provided. The winch includes a device for removing water adhering to the cable's outer surface. The two winding modes are designed to assist in removing water from the cable's outer surface: continuous winding and intermittent winding. The continuous winding mode is used when there is little water adhering to the cable's outer surface, while the intermittent winding mode is used when there is more water adhering to the cable's outer surface. Specifically, it includes a frame 01 mounted on both sides for overall winch installation, a winding reel 300 for winding and unwinding the cable, a rope guide 400 in front of the winding reel 300, and an active winding device 500 in front of the rope guide 400. A blower assembly 800 for removing water adhering to the cable's outer surface is located between the rope guide 400 and the active winding device 500. The blower assembly 800 consists of a housing 801 and several fans 802 mounted on the upper part of the housing 801.

[0035] A handle frame 600 is provided above the take-up reel 300; the handle frame 600 consists of handles on both sides and a horizontal connecting plate 610 in the middle, and the handles on both sides are connected to the frame body 01 on both sides to form a good whole.

[0036] The rope guide 400 includes a reciprocating transmission assembly 340 disposed at the lower part of the horizontal connecting plate 610, and a rope guide base plate 430 connected to two frames 01 at both ends respectively. The rope guide base plate 430 is plate-shaped with an obtuse-angled folded edge, forming two opposing upper and lower areas after the fold. A set of track translation assembly 431 is provided above the fold 02, and a long strip-shaped moving guide groove 432 is provided below the fold 03. The cross-section of the moving guide groove 432 is arc-shaped, and a sliding guide 433 matching the arc shape and capable of sliding closely is provided in the arc-shaped cross-section.

[0037] The sliding guide 433 is fixedly connected to the slider of the track translation component 431 by the first connector 004. The center of the sliding guide 433 is a cylinder with a through hole for the cable to pass through. The edges at both ends of the hole have rounded chamfers. Several flexible support members are provided on the circumference of the cylinder. When the cable flows in the through hole, the cylinder can have a certain swing amplitude under the support of the flexible support members to reduce the vibration caused by the cable flow.

[0038] The top of the enclosure 801 is provided with an elongated opening for the first connector 004 to move, and the bottom of the enclosure 801 is provided with several drainage holes.

[0039] The active cable retraction device 500 includes a dragging motor assembly 510 disposed on the upper part of the horizontal connecting plate 610, a cable retrieval motor 520 disposed on the dragging motor assembly 510, and a dragging connector 530 whose one end is fixedly connected to a slider in the dragging motor assembly 510 and whose other end is fixedly connected to a lead screw nut in the reciprocating transmission assembly 340; the dragging connector 530 passes through the horizontal connecting plate 610, and an elongated opening for the dragging connector 530 to move is provided at a corresponding position on the horizontal connecting plate 610;

[0040] The active take-up device 500 also includes a combined transmission component 540 for take-up, and an automatic disconnection mechanism 550 that is triggered when the cable is pulled by a foreign object during take-up, causing the take-up resistance to increase to a limit. The combined transmission component 540 includes a continuous take-up component 5410 and an intermittent take-up component 5420, as well as a take-up mode switching component 5430 for switching between the two, and also includes a take-up execution component 5440.

[0041] The continuous take-up assembly 5410 includes a generally H-shaped assembly mounting frame 5411 fixedly connected to the slider in the track translation assembly 431, a movable retaining shaft 5412 installed in the assembly mounting frame 5411, a first synchronous drive wheel 5413 installed in the movable retaining shaft 5412, a second synchronous drive wheel 5414 fixedly connected to the output shaft of the cable take-up motor 520, and a first synchronous drive belt 5415 connecting the first synchronous drive wheel 5413 and the second synchronous drive wheel 5414 for belt drive. The cable take-up motor 520 starts and drives the second synchronous drive wheel 5414 to rotate, which in turn drives the first synchronous drive wheel 5413 to rotate via the first synchronous drive belt 5415. The first synchronous drive wheel 5413 then drives the movable retaining shaft 5412 to rotate, thus achieving continuous transmission. The lower part of the lead screw nut in the reciprocating transmission assembly 340 is fixedly connected to the assembly mounting frame 5411 via a second connector 005.

[0042] The intermittent cable reel assembly 5420 includes a one-way drive flywheel 5421 mounted in a movable retaining shaft 5412, an eccentric cam 5422 fixedly connected to the output shaft of the cable reel motor 520, and a reciprocating rigid chain belt 5423 that connects the one-way drive flywheel 5421 and the eccentric cam 5422 via a one-way chain drive. The one-way drive flywheel 5421 is configured to rotate clockwise and idle when rotating counterclockwise. The reciprocating rigid chain belt 5423 is generally long and narrow, with one end being a single-sided slat and the other end being a rectangular frame with three sides. A chain belt matching the tooth profile of the one-way drive flywheel 5421 is fixedly installed within the frame. The side of the slat has a long movable hole 5424. The movable hole 5424 is used to set a limit so that after the eccentric cam 5422 rotates, the hinge point between the reciprocating rigid chain belt 5423 and the eccentric cam 5422 changes cyclically with the rotation position of the eccentric cam 5422. That is, under the limit of the movable hole 5424, the reciprocating rigid chain belt 5423 moves back and forth while rotating slightly, thereby realizing intermittent transmission to the one-way transmission flywheel 5421. That is, when the reciprocating rigid chain belt 5423 pushes forward, the one-way transmission flywheel 5421 spins idly, and when the reciprocating rigid chain belt 5423 pulls backward, it drives the movable retaining shaft 5412 to rotate effectively.

[0043] like Figures 7-9 As shown, the take-up mode switching component 5430 includes a lifting rod 5431 with one end slidably connected to the movable elongated hole 5424, a lifting slide 5432 disposed in the component mounting frame 5411, a lifting slider 5433 mounted in the lifting slide 5432, and a mode switching knob 5434 disposed above the lifting slide 5432 and threadedly connected to it; the threaded end of the mode switching knob 5434 is connected to the lifting slider 5433, and the other end of the lifting rod 5431 is connected to the lifting slider 5433. The rotating mode switching knob 5434 allows the lifting slider 5433 to slide up and down along the lifting slide block 5432, and the lifting rod 5431 moves synchronously. The lifting rod 5431 then drives the reciprocating rigid chain belt 5423 to move up and down, thereby realizing the engagement or disengagement between the reciprocating rigid chain belt 5423 and the one-way transmission flywheel 5421. The lifting rod 5431 is provided with baffles on both the inner and outer sides that cooperate with the movable elongated hole 5424, so that the reciprocating rigid chain belt 5423 can be relatively stable when it pushes and pulls.

[0044] The take-up mode switching component 5430 also includes a tensioning member 5400 disposed in the component mounting frame 5411 on one side facing the take-up reel 300. The tensioning member 5400 includes a first tensioning pulley 5401 pressing against the first synchronous transmission belt 5415, a transition arm 5402 rotatably connected at one end to the first tensioning pulley 5401 and having a roller at the other end, and a lifting and loosening part 5403 having a certain clearance fit with the roller of the transition arm 5402; the transition arm 5402 is hinged in the middle to the component mounting frame 5411, and at the hinge point it is close to the first tensioning pulley 5401. One side of the first tensioning pulley 5401 is provided with an elastic element 5404 that presses against the adapter arm 5402; the elastic element 5404 ensures that the first tensioning pulley 5401 always presses against the first synchronous transmission belt 5415 and leaves a gap between the roller of the adapter arm 5402 and the upper part of the lifting tensioning part 5403, which provides elastic space for the first tensioning pulley 5401, so that the tension can change with the belt when the force changes; here, the first synchronous transmission belt 5415 is in a relaxed state when the first tensioning pulley 5401 does not have sufficient pressure;

[0045] How the 5430 take-up mode switching component works:

[0046] The overall function of the take-up mode switching component 5430 is to switch between the continuous drive of the continuous take-up component 5410 and the intermittent drive of the intermittent take-up component 5420. Specifically, rotating the mode switching knob 5434 clockwise moves the lifting slider 5433 upward, causing the lifting tensioning part 5403 to abut against the roller of the adapter arm 5402. As the lifting slider 5433 continues to move upward, the roller moves inward to the inside of the lifting tensioning part 5403. At the same time, the first tensioning wheel 5401 on the adapter arm 5402 begins to press the first synchronous drive belt 5415 until the first synchronous drive belt 5415 is tightened, which means the first synchronous drive wheel 5413 and the second synchronous drive... Wheel 5414 forms an effective transmission. During the upward movement of the lifting slider 5433, the reciprocating rigid chain belt 5423 is continuously lifted upward by the lifting rod 5431. When the first tensioning wheel 5401 is fully tightened, the reciprocating rigid chain belt 5423 and the one-way transmission flywheel 5421 are completely separated. At this time, it is a continuous transmission mode. Conversely, rotating the mode switching knob 5434 in the opposite direction can realize the engagement of the reciprocating rigid chain belt 5423 and the one-way transmission flywheel 5421 and switch back to the intermittent transmission mode. Correspondingly, the first synchronous transmission belt 5415 returns to the loose state, and the first synchronous transmission wheel 5413 and the second synchronous transmission wheel 5414 also return to the ineffective state.

[0047] The component mounting frame 5411 has a backrest 5416 on the side facing the take-up reel 300, and the movable retaining shaft 5412 is located in front of the backrest 5416.

[0048] The automatic disconnection mechanism 550 includes movable through holes 551 disposed in the two side walls of the component mounting frame 5411, and an elastic bearing 552 hinged to the backrest 5416. The movable through hole 551 is used to install the movable retaining shaft 5412. The movable through hole 551 is generally inclined in the shape of a heart, with the inclination angle extending downwards. Its purpose is to guide the movable retaining shaft 5412 to move downwards under tension. The hinge point of the elastic bearing 552 needs to be higher than the axis of the movable retaining shaft 5412. That is, under normal conditions, the elastic bearing 552 presses the movable retaining shaft 5412 against the upper part of the inclined heart shape of the movable through hole 551 from top to bottom at an angle. Furthermore, the elastic bearing 552 is set in the first synchronous transmission. Between wheel 5413 and one-way drive flywheel 5421, the imbalance generated when overcoming elastic bearing 552 is relatively small. In this embodiment, since the thrust of elastic bearing 552 on movable shaft 5412 and the tension of the first synchronous transmission belt 5415 and reciprocating rigid chain belt 5423 are not on the same straight line, when the tension is greater than the support force, the movable shaft 5412 will tilt and fall. Since the locking point at the connection between the upper and lower parts of the movable through hole 551 is designed to be relatively small, one end of the movable shaft 5412 will be driven by the tension to fall into the lower part of the movable through hole 551 first, and the other end will also fall into the lower part of the movable through hole 551 under the action of tension due to the small locking point.

[0049] The automatic disconnection mechanism 550 also includes a reset assembly 553 in front of the movable card shaft 5412; the reset assembly 553 includes a reset waist hole 554 disposed on one side wall of the component mounting frame 5411 and located obliquely below the movable through hole 551, a reset push block 555 abutting against the inner side wall of the component mounting frame 5411, a guide shaft 556 with one end passing through the reset push block 555 and partially exposed, and the other end movably installed in the reset waist hole 554 and partially exposed, a reset knob 557 installed in front of the component mounting frame 5411, a fixing block 558 for installing the reset knob 557, two reset tension springs 559 disposed at both ends of the guide shaft 556, and a guide plate 555a disposed at the lower part of the reset push block 555 and fixed on the inner side wall of the component mounting frame 5411;

[0050] The reset push block 555 has an inclined surface at the front and two rollers at the bottom. These rollers are mounted on the upper surface of the guide plate 555a. One end of each of the two reset tension springs 559 is connected to both ends of the guide shaft 556, and the other end is connected to both ends of the fixing block 558. The reset knob 557 is hinged to the reset push block 555. The reset waist hole 554 and the guide plate 555a are horizontally positioned at one end near the reset knob 557, and the other end is inclined upwards at the same angle. This arrangement is intended to allow the reset knob 557 to be rotated to reset the mechanism when the automatic disconnect mechanism 550 is in the disconnected state (i.e., the movable retaining shaft 5412 falls below the movable through hole 551). Figure 8 and Figure 9 The reset knob 557 pushes the reset push block 555 forward against the tension of the two reset springs 559 until its inclined surface is aligned with the ground surface. Figure 9 The dotted line indicates that the movable retaining shaft 5412 is in contact with the ground. Continuing to rotate the lower reset push block 555 pushes the movable retaining shaft 5412 forward. At this time, guided by the guide plate 555a and the reset waist hole 554, the guide shaft 556 tilts the reset push block 555 upwards, thus moving the movable retaining shaft 5412 upwards until it re-enters the upper part of the movable through hole 551 to complete the reset. Then, rotating the reset knob 557 in the opposite direction returns the reset push block 555 to its initial position. It should be noted that if the elastic bearing 552 has a large elastic force, the reset assembly 553 needs to be further configured on the other side wall of the assembly mounting frame 5411 as follows: Figure 3 As shown, this method involves operating both sides simultaneously during the reset process, making the reset easier to complete.

[0051] The operating principle of the automatic disconnection mechanism 550:

[0052] When the cable is pulled by a foreign object during winding, the force of the first synchronous drive belt 5415 or the reciprocating rigid chain belt 5423 will increase. This will overcome the pressure of the elastic bearing 552, causing the movable retaining shaft 5412 to move upward along the movable through hole 551. In other words, the movable retaining shaft 5412 will disengage from its original stable position and, guided by the movable through hole 551 and under the weight of the movable retaining shaft 5412 and the upper-mounted components, will pass through the pressure of the elastic bearing 552 and enter the movable through hole. At the lower position of hole 551, the elastic pressing relationship between tension wheel 5445 and second synchronous belt 5444 provides room for movement. After the movable retaining shaft 5412 enters the lower position of movable through hole 551, the position of third synchronous wheel 5441 moves down, thereby the second synchronous belt 5444 is in a disabled state. At this time, the winding stops, protecting the cable. Here, a monitoring sensor is set on the second synchronous belt 5444 to synchronously set the drive motor of winding reel 300 to stop.

[0053] The take-up execution assembly 5440 includes a third synchronous pulley 5441 installed in the movable card shaft 5412, a transfer shaft 5442 located at the lower part of the assembly mounting frame 5411, a fourth synchronous pulley 5443 installed in the transfer shaft 5442, a second synchronous belt 5444 that connects the third synchronous pulley 5441 and the fourth synchronous pulley 5443 by belt drive, a tensioning pulley 5445 for the second synchronous belt 5444, an extension mounting plate 5446 located at the lower part of the assembly mounting frame 5411, a synchronous transmission kit 5447 located between the end of the extension mounting plate 5446 and the transfer shaft 5442, and two sets of conveyor wheel assemblies 700 located on both sides of the end of the extension mounting plate 5446.

[0054] The conveyor wheel assembly 700 includes a ball-cage universal joint 701 coaxially connected at one end to the synchronous wheel of the synchronous transmission kit 5447, a conveyor wheel 702 rotatably mounted on the extension mounting plate 5446, the other end of the ball-cage universal joint 701 connected to the conveyor wheel 702, a wire diameter adjustment component 703 located on the side of the conveyor wheel 702 facing the take-up reel 300, and a locking knob 704 for locking the wire diameter adjustment component 703. An arc-shaped wire groove 705 is provided on the extension mounting plate 5446 below the wire diameter adjustment component 703. The front of the wire diameter adjustment component 703 has a rotatable pressure shaft, and a longitudinal waist hole in the center. The waist hole is used to adjust the distance between the pressure shaft and the conveyor wheel 702 to control the tension of the cable, and is then locked by the locking knob 704. The ball-cage universal joint 701 allows the conveyor wheels 702 to rotate within a certain range when the rope guide 400 moves, resulting in smoother cable transmission.

[0055] Overall usage process steps:

[0056] 1. The upper part of the lead screw nut in the reciprocating transmission assembly 340 is fixedly connected to the dragging connector 530, and the lower part of the lead screw nut is fixedly connected to the assembly mounting frame 5411 through the second connector 005. After the drive motor in the reciprocating transmission assembly 340 drives the lead screw to rotate, the lead screw nut drives the dragging connector 530 and the assembly mounting frame 5411 to move laterally accordingly. That is, the rope guide 400 and the active take-up device 500 move synchronously under the control of the motor. When it is used for wire feeding, the wire diameter adjustment component 703 is loosened so that the conveying wheel 702 only plays a transitional transmission role, and the rope guide 400 moves back and forth in sequence according to the corresponding wire feeding speed.

[0057] 2. When winding up the cable, tighten the two wire diameter adjustment parts 703, and then select the intermittent winding mode or the continuous winding mode according to the water surface of the cable. The wound cable is dried by the blower assembly 800 and then the cable guide 400 works together with the winding reel 300 and the active winding device 500 to complete the winding.

[0058] 3. When the cable is tethered during take-up, the automatic disconnect mechanism 550 disconnects the take-up as described above, and after the problem is resolved, it is reset by the reset component 553 following the aforementioned operating steps.
