Description

Technical Field

[0001] This invention relates to the technical field of cables, and more particularly to a graphene tensile cable and a cable winding device. Background Technology

[0002] With the rapid development of power transmission, communication engineering, and industrial equipment connection, cables, as core transmission components, are facing increasingly complex application scenarios and higher performance requirements. However, existing cables still have many shortcomings in practical applications, making it difficult to meet the needs of high-load and complex environments. Traditional cables rely mainly on ordinary fiber reinforcement layers for tensile strength. These materials have limited strength and fatigue resistance. During cable laying, winding and handling, or long-term suspension, they are prone to breakage of the internal conductor core and damage to the insulation layer due to external pulling, which directly affects the service life and transmission safety of the cable.

[0003] Regarding cable winding devices, existing winding devices also have significant drawbacks: most devices only use a single winding roller to wind the cable, lacking an effective guiding unit. During the winding process, the cable tends to accumulate unevenly and become loose on the roller surface. Before winding, one end of the cable needs to be fixed to the winding roller. When fixing the cable end to the winding roller, manual binding or simple clip structures are often used, resulting in poor fixing reliability. In the early stages of winding, the cable end is prone to falling off the winding roller, requiring repeated machine stops for adjustment, which seriously affects winding efficiency. Therefore, it is necessary to provide a graphene tensile cable and a cable winding device to solve the above technical problems. Summary of the Invention

One end of the worm is fixedly connected to a handle.

[0015] Compared with related technologies, the graphene tensile cable and cable winding device provided by the present invention have the following beneficial effects: The outermost protective layer of the cable can resist external friction and acid / alkali corrosion damage, effectively protecting the internal structure of the cable. The outer insulation sheath strengthens the overall insulation performance of the cable, preventing external moisture and impurities from entering the interior. The tensile reinforcement layer is woven from graphene fiber and aramid fiber. The aramid fiber provides the cable with basic high strength, while the graphene fiber further improves the cable's tensile strength and fatigue resistance. It can withstand external tension during cable laying and winding, and distributes the tension more evenly, reducing the risk of damage to the internal structure. The conductor core is made of copper and graphene composite wires twisted together. The copper material ensures the basic conductivity of the cable, while the graphene can fill copper lattice defects, improve electron mobility, further optimize the cable's conductivity and reduce current transmission loss. At the same time, the combination of the twisted structure and the high strength characteristics of graphene can enhance the tensile strength of the conductor core itself, reduce the risk of breakage during use or winding, and ensure the cable's service life.

[0016] The shielding layer is a graphene-modified copper mesh. Graphene can improve the conductivity and corrosion resistance of the copper mesh. The shielding layer can not only shield external electromagnetic interference, but also reduce the electromagnetic signal radiation of the cable itself, ensuring stable current transmission. The inner insulation sheath can effectively isolate the conductor core from the external structure.

[0017] Rotating the handle drives the worm gear to rotate, which in turn drives the vertical threaded rod to rotate. The rotation of the vertical threaded rod causes the first lifting sleeve, the second lifting sleeve, and the horizontal slide rod to rise and fall synchronously. When the horizontal slide rod moves the housing upward, it increases the distance between the pressure roller in the pressing component and the third pulley in the guide component, making it easier to place the cable. When the horizontal slide rod moves the housing downward, it makes the pressure roller press the cable on the third pulley more tightly. This increases the friction between the pressure roller and the third pulley when the take-up roller is winding the cable, keeping the cable taut and preventing it from loosening during winding. Furthermore, when the second lifting sleeve moves downward, it drives the actuating column to slide downward in the inclined guide groove on the side frame of the pressing component, controlling the side frame and the side pressure plate rotatably connected to it to move closer to the side circular plate. This facilitates pressing and fixing the end of the cable protruding from the perforation, preventing the cable end from falling off the take-up roller during winding, ensuring the reliability of the fixation in the initial stage of winding, eliminating the need for repeated stops for adjustment, and improving efficiency.

[0018] During winding, the motor in the winding unit drives the winding roller to rotate, thereby winding the cable. At the same time, it drives the active synchronous pulley to rotate, which in turn drives the driven synchronous pulley and the reciprocating screw to rotate via the synchronous belt. When the reciprocating screw rotates, the reciprocating screw nut moves back and forth along the first crossbar, which drives the mounting bracket and guide unit fixed on the top of the reciprocating screw nut to move back and forth, so that the cable can be wound more evenly on the winding roller.

[0019] In the guide unit, the cable passes around the fourth pulley, and the drive wheel contacts the upper surface of the cable. As the housing moves downward, the drive wheel stops due to the cable's obstruction. The connecting frame continues to move downward, compressing the third spring. The guide block moves upward relative to the lifting frame, and the inclined guide part of the guide block pushes the push wheel to move, causing the sliding frame to slide along the second crossbar and compress the second spring. The sliding frame presses the self-reset button switch, energizing and starting the motor. When the cable is fully wound, the other end of the cable disengages from the fourth pulley, the drive wheel loses cable resistance, the elastic potential energy of the third spring is released, pushing the lifting frame and guide block downward. The push wheel disengages from the vertical guide part of the guide block, the elastic potential energy of the second spring is released, pushing the sliding frame away from the self-reset button switch. The self-reset button switch disconnects the circuit, and the motor automatically stops, eliminating the need for manual monitoring of the start / stop status and saving labor costs.

[0020] In this invention, through the cooperation of the winding unit, the guiding unit, and the pressing unit, the pressing roller, together with the third pulley and the side pressing plate, achieves cable clamping. At the same time, the transmission wheel triggers the guide block to push the push roller, which causes the self-resetting button switch to control the motor to start and stop. The motor synchronously drives the reciprocating screw and the reciprocating screw nut to make the cable more evenly wound on the winding roller. The three linkages realize the cable winding action, making the cable winding more stable. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0024] Please refer to the following: Figures 1 to 2 A graphene tensile cable includes a shielding layer 104, a tensile reinforcing layer 103 covering the outside of the shielding layer 104, an outer insulating sheath 102 covering the outside of the tensile reinforcing layer 103, a protective layer 101 covering the outside of the outer insulating sheath 102, a plurality of evenly arranged conductor cores 106 disposed on the inner side of the shielding layer 104, an inner insulating sheath 105 covering the outside of the conductor cores 106, and a filler layer 107 filling the space between the inner insulating sheath 105 and the shielding layer 104. The protective layer 101 is made of polytetrafluoroethylene (PTFE) film spirally wound; the conductor core 106 is made of copper and graphene composite wire twisted together, with the mass fraction of graphene in the copper and graphene composite wire being 0.5-2wt%; the tensile reinforcing layer 103 is made of graphene fiber and aramid fiber woven together, with the mass ratio of graphene fiber to aramid fiber being 1:3-1:5, and the weaving density of the tensile reinforcing layer 103 being ≥90%; the filling layer 107 can be a flexible insulating filler, which can be polypropylene rope or glass fiber rope; the inner insulating sheath 105 is a cross-linked polyethylene layer with 0.1-0.3wt% graphene microsheets added; the outer insulating sheath 102 is a flame-retardant polyolefin layer with 0.2-0.5wt% graphene nanosheets added; the shielding layer 104 is a graphene-modified copper mesh with a mesh count of 80-120 mesh and a thickness of 0.1-0.3mm.

[0025] In the above-mentioned structure, the protective layer 101 is made of polytetrafluoroethylene (PTFE) film spirally wound. Due to its excellent abrasion resistance and acid / alkali resistance, it can resist external environmental corrosion and protect the internal structure of the cable 1. The conductor core 106 is a copper and graphene composite wire stranded together, with a graphene mass fraction of 0.5-2 wt%. Copper ensures basic conductivity, while graphene fills copper lattice defects, improves electron mobility, and reduces current transmission loss. The stranded structure also enhances its tensile strength. The tensile reinforcement layer 103 is woven with graphene fibers and aramid fibers in a mass ratio of 1:3-1:5, with a weaving density ≥90%. The high-strength foundation is provided by graphene fiber, which enhances fatigue resistance and can evenly distribute external forces during laying and winding, preventing damage to the internal structure. The filler layer 107 is made of polypropylene rope or glass fiber rope, which can fill the gap between the inner insulation sheath 105 and the shielding layer 104, offsetting the stress generated by bending and vibration of the cable 1, and ensuring the stability of the conductor core 106. The shielding layer 104 is an 80-120 mesh, 0.1-0.3mm thick graphene-modified copper mesh. Graphene enhances its conductivity and corrosion resistance, can shield external electromagnetic interference, reduce its own electromagnetic signal radiation, and ensure stable current transmission. Example

[0026] For further details, please refer to the following: Figures 1 to 6 A graphene tensile cable winding device includes: a support frame 2, a winding unit 4 installed on one upper side of the support frame 2, a wire pressing unit 6 installed on the other upper side of the support frame 2, and a guide unit 5 installed on the wire pressing unit 6; the winding unit 4 is used to wind up the cable 1; the guide unit 5 is used to automatically start the winding unit 4 to perform the winding action after the cable 1 is pressed; the wire pressing unit 6 is used to press and limit one end of the cable 1 on the winding unit 4.

[0027] In the above, the winding unit 4 is used to wind up the cable 1, and the pressing unit 6 and the guiding unit 5 are respectively responsible for fixing the end of the cable 1 and pressing and starting / stopping linkage. The three work together to solve the problems of the cable 1 easily falling off and lacking guidance when winding in traditional devices, and ensure the stability during winding.

[0028] Furthermore, the winding unit 4 includes a winding component 41 and a reciprocating component 42; the winding component 41 includes a winding roller 411, both ends of which are rotatably connected to the frame wall of the support frame 2. One end of the winding roller 411 is fixedly connected to a side circular plate 412 coaxially arranged therewith. A through hole 414 is provided through the winding roller 411 and the side circular plate 412. The outlet end of the through hole 414 is coaxially arranged with the winding roller 411. A motor 413 is fixedly installed on the frame wall of the support frame 2. The other end of the winding roller 411 is fixedly connected to the rotating end of the motor 413.

[0029] In the above, in the winding component 41 of the winding unit 4, the two ends of the winding roller 411 are rotatably connected to the support frame 2 wall, which has strong rotational stability. The side circular plate 412 provides support for the clamping of the end of the cable 1. The through hole 414 facilitates the insertion and fixing of the end of the cable 1. The motor 413 drives the winding roller 411 to rotate, providing stable and efficient power for the winding action.

[0030] Furthermore, the reciprocating component 42 includes a reciprocating lead screw 421, which is rotatably connected to the wall of the support frame 2. A matching reciprocating lead screw nut 422 is installed on the reciprocating lead screw 421. A first crossbar 426, which is parallel to the reciprocating lead screw 421, is fixedly connected to the wall of the support frame 2. The reciprocating lead screw nut 422 is laterally slidably sleeved on the outside of the first crossbar 426. A driven synchronous pulley 423 is fixedly connected to one end of the reciprocating lead screw 421. A driving synchronous pulley 424 is fixedly sleeved on the outside of the rotating end of the motor 413. The driving synchronous pulley 424 and the driven synchronous pulley 423 are connected by a synchronous belt 425.

[0031] In the above, the reciprocating screw 421 is rotatably connected to the support frame 2 and is arranged parallel to the take-up roller 411. The driven synchronous pulley 423 at one end is connected to the driving synchronous pulley 424 at the rotating end of the motor 413 through the synchronous belt 425, which can ensure that the reciprocating screw 421 and the take-up roller 411 rotate synchronously. The reciprocating screw nut 422 is sleeved on the reciprocating screw 421 and slidably sleeved on the outside of the first crossbar 426. The first crossbar 426 restricts the reciprocating screw nut 422 from rotating with the screw, so that it only makes reciprocating linear motion along the first crossbar 426, thereby driving the subsequent guide unit 5 to reciprocate synchronously, so that the cable 1 is evenly wound on the surface of the take-up roller 411. Example

[0032] For further details, please refer to [link / reference]. Figures 1 to 10Based on Embodiment 2, the guide unit 5 includes a guide component 51, a pressing component 52, an opening and closing component 53, and a transmission component 54. The guide component 51 includes a mounting frame 511, which is fixedly connected to the top of the reciprocating screw nut 422. One end of the mounting frame 511 is rotatably connected to a second pulley 513, and the other end of the mounting frame 511 is rotatably connected to a fourth pulley 515.

The several third pulleys 514 are located between the second pulley 513 and the fourth pulley 515. A vertical connecting rod 516 is fixedly connected to the top of the mounting frame 511.

[0033] In the above, the mounting bracket 511 is fixed to the top of the reciprocating screw nut 422 and can reciprocate synchronously with the reciprocating screw nut 422 to ensure coordination between the guiding and winding actions. The third pulley 514 is located between the second pulley 513 and the fourth pulley 515 and provides support for the cable 1. The vertical connecting rod 516 is fixed to the top of the mounting bracket 511, which not only provides a mounting base for the pressing component 52, but also allows the housing 521 to slide vertically along the vertical connecting rod 516 to ensure precise cooperation between the pressing component 52 and the third pulley 514.

[0034] Furthermore, the pressing component 52 includes a housing 521, which is positioned above the mounting bracket 511 and is vertically slidably connected to the vertical connecting rod 516. A plurality of pressure rollers 522 are equidistantly arranged on the inner side of the housing 521. Each end of a pressure roller 522 is rotatably connected to a lifting slider 523. Each pressure roller 522 corresponds to a third pulley 514, and the pressure roller 522 is located directly above the corresponding third pulley 514. A groove 525 corresponding to each lifting slider 523 is opened on the side wall of the housing 521. The lifting slider 523 is slidably connected within the corresponding groove 525. A first spring 524 is fixedly connected to the top of the lifting slider 523, and the top of the first spring 524 is fixedly connected to the top of the inner side of the groove 525.

[0035] In the above, the housing 521 is slidably sleeved on the vertical connecting rod 516.

The lifting sliders 523 at both ends of the pressure roller 522 are slidably connected in the groove 525 of the housing 521. The top of the lifting slider 523 is connected to the top of the groove 525 through the first spring 524. The elasticity of the first spring 524 makes the pressure roller 522 press on the cable 1, thereby keeping the cable 1 in a taut state and preventing it from becoming loose during winding.

[0036] Furthermore, the opening and closing component 53 includes a fixed side block 531, which is fixedly connected to the top of the housing 521. Two parallel second crossbars 532 are symmetrically fixedly connected to one side of the fixed side block 531. A sliding frame 533 is slidably sleeved on the two second crossbars 532.

One end of the second spring 536 is fixedly connected to the side wall of the fixed side block 531, and the other end of the second spring 536 is fixedly connected to one side of the sliding frame 533.

[0037] In the above, the fixed side block 531 is fixed to the top of the housing 521, providing mounting support for the two parallel second crossbars 532. The sliding frame 533 is slidably sleeved on the second crossbars 532. The second crossbars 532 restrict the sliding frame 533 to only make lateral movements. The self-reset button switch 534 is fixed on one side of the fixed side block 531 and directly opposite the sliding frame 533. The push wheel 535 on the other side of the sliding frame 533 can convert the vertical movement of the guide block 546 into the lateral movement of the sliding frame 533. The second spring 536 is sleeved on the outside of the second crossbar 532 and its two ends are respectively connected to the fixed side block 531 and the sliding frame 533. Under normal conditions, pushing the sliding frame 533 away from the self-reset button switch 534 will de-energize the motor 413. The motor 413 will be energized only when the sliding frame 533 presses the button of the self-reset button switch 534, realizing automatic start and stop.

[0038] Furthermore, the transmission component 54 includes a connecting frame 541. One end of the connecting frame 541 is fixedly connected to the shell wall of the housing 521. The other end of the connecting frame 541 is vertically slidably connected to a vertical slide rod 542. The bottom end of the vertical slide rod 542 is fixedly connected to a lifting frame 543. The bottom of the lifting frame 543 is rotatably connected to a transmission wheel 544. A guide block 546 is fixedly connected to one side of the lifting frame 543. The guide block 546 is provided with an inclined guide part 547 and a vertical guide part 548 on the side near the push wheel 535. The distance from the top of the inclined guide part 547 to the push wheel 535 is greater than the distance from its bottom to the push wheel 535. The bottom end of the inclined guide part 547 and the top end of the vertical guide part 548 are transitioned by a rounded corner. A third spring 545 is sleeved on the outside of the vertical slide rod 542. The top end of the third spring 545 is fixedly connected to the frame wall of the connecting frame 541, and the bottom end of the third spring 545 is fixedly connected to the top of the lifting frame 543.

[0039] In the above, one end of the connecting frame 541 is fixed to the housing 521 and rises and falls synchronously with the housing 521. The bottom end of the vertical slide rod 542, which is slidably connected to the other end, is fixed to the lifting frame 543. The transmission wheel 544 at the bottom of the lifting frame 543 can make close contact with the surface of the cable 1 to accurately sense the presence of the cable 1. The two ends of the third spring 545 on the outside of the vertical slide rod 542 are connected to the connecting frame 541 and the lifting frame 543 respectively, providing downward pressure to the transmission wheel 544 to ensure that it is in contact with the cable 1. The guide block 546 on one side of the lifting frame 543 is provided with an inclined guide part 547 and a vertical guide part 548. The distance from the top of the guide section 547 to the push roller 535 is greater than that from the bottom. When the housing 521 moves downward, the inclined guide section 547 can gradually push the push roller 535, causing the sliding frame 533 to press the self-reset button switch 534. After the push roller 535 enters the vertical guide section 548, it can keep the switch closed. When the cable 1 is wound up and disengaged from the transmission wheel 544, the third spring 545 resets and drives the guide block 546 to move downward. The push roller 535 disengages from the vertical guide section 548, the second spring 536 pushes the sliding frame 533 to reset, the self-reset button switch 534 is de-energized, the motor 413 stops working, and the winding action stops. Example

[0040] For further details, please refer to [link / reference]. Figures 1 to 11 Based on Embodiment 3, the pressing unit 6 includes a pressing component 61 and a control component 62. The pressing component 61 includes a side frame 611. One end of the side frame 611 is provided with a through oblique guide groove 612. The other end of the side frame 611 is rotatably connected to a side pressure plate 613 coaxially arranged with the side circular plate 412. Two positioning blocks 614 are symmetrically fixedly connected to the side of the side pressure plate 613 near the side circular plate 412. A counterweight block 615 is fixedly connected to the lower part of the side pressure plate 613. Two parallel guide crossbars 616 are symmetrically fixedly connected to the frame wall of the support frame 2. The side frame 611 is laterally slidably sleeved on the outside of the two guide crossbars 616. One end of the two guide crossbars 616 is fixedly connected to a side strip 617. A toggle post 618 is slidably arranged on the inner side of the oblique guide groove 612.

[0041] In the above, the side frame 611 is slidably sleeved on the outside of the two guide crossbars 616 on the support frame 2. The guide crossbars 616 ensure that the side frame 611 moves smoothly in the lateral direction. The side strip 617 is fixed to one end of the guide crossbar 616 to improve the stability of the guide crossbar 616. The actuating column 618 is slidably installed in the inclined guide groove 612 at one end of the side frame 611, which can convert the vertical movement of the actuating column 618 into the lateral movement of the side frame 611. The side pressure plate 613 rotatably connected to the other end of the side frame 611 is coaxial with the side circular plate 412. The two positioning blocks 614 on the side pressure plate 613 can restrict the cable 1 extending from the through hole 414 between them. When there is no external force, the counterweight block 615 at the bottom of the side pressure plate 613 maintains the initial state of the side pressure plate 613 through its own weight, thereby keeping the two positioning blocks 614 vertically positioned.

[0042] Furthermore, the control component 62 includes a horizontal slide bar 621, which is laterally slidably connected to the housing 521. One end of the horizontal slide bar 621 is fixedly connected to a first lifting sleeve 622, and the other end of the horizontal slide bar 621 is fixedly connected to a second lifting sleeve 623. One end of the actuating column 618 is fixedly connected to the side wall of the second lifting sleeve 623. A vertical rod 624 is slidably connected vertically through the second lifting sleeve 623. A strip 629 is fixedly connected to the top of the vertical rod 624, and the bottom end of the vertical rod 624 is fixedly connected to the frame wall of the support frame 2. A vertical threaded rod 625 is rotatably connected to the bottom of the strip 629, and the bottom end of the vertical threaded rod 625 is rotatably connected to the frame wall of the support frame 2. A worm gear 626 is fixedly sleeved on the upper outer side of the vertical threaded rod 625. A worm 627 is laterally rotatably connected through the frame wall of the support frame 2. The worm 627 meshes with the worm gear 626, and a handle 628 is fixedly connected to one end of the worm 627.

[0043] In the above, the horizontal sliding rod 621 slides laterally through the housing 521, and its two ends are respectively connected to the first lifting sleeve 622 and the second lifting sleeve 623, which can drive the two to rise and fall synchronously, ensuring that the pressing action of the guide unit 5 and the fixing action of the pressing unit 6 are coordinated. The vertical threaded rod 625 is rotatably connected between the plate 629 and the support frame 2. The worm wheel 626 on its outer side meshes with the worm 627 on the support frame 2. The handle 628 at one end of the worm 627 is easy to operate manually, and the structure of the worm 627 and the worm wheel 626 has self-locking properties, which can accurately control the rotation of the vertical threaded rod 625, thereby adjusting the height of the first lifting sleeve 622.

[0044] Furthermore, a storage battery 7 is fixedly installed on the wall of the support frame 2, and the motor 413 is electrically connected to the self-reset button switch 534 through a wire. The self-reset button switch 534 is electrically connected to the storage battery 7 through a wire. Four walking wheels 3 are symmetrically fixedly installed at the bottom of the support frame 2.

[0045] In the above, the battery 7 is fixed on the wall of the support frame 2 to provide independent power for the device, so that the device does not need to rely on an external power source. The battery 7 forms a closed circuit with the self-reset button switch 534 and the motor 413 through wires, ensuring that the self-reset button switch 534 can accurately control the power supply of the motor 413. The four wheels 3 at the bottom of the support frame 2 are symmetrically distributed to facilitate the movement of the device.

[0046] The working principle of the graphene tensile cable and cable winding device provided by this invention is as follows: The outermost protective layer 101 of the graphene tensile cable is made of polytetrafluoroethylene (PTFE) film, which can directly resist physical and chemical damage such as external friction and acid / alkali corrosion, protecting the internal structure. The inner outer insulating sheath 102 is a flame-retardant polyolefin layer with 0.2-0.5 wt% graphene nanosheets added, which enhances the overall insulation performance, prevents external moisture and impurities from intruding, and also possesses good flame retardancy and weather resistance, adapting to complex environments. The inner side of the outer insulating sheath 102... The tensile reinforcement layer 103 is woven from graphene fibers and aramid fibers in a mass ratio of 1:3 to 1:5. The aramid fibers provide basic high strength, while the graphene fibers further enhance tensile strength and fatigue resistance, enabling it to withstand external tension during cable laying and winding, and evenly distributing the tension to reduce damage to the internal structure. The shielding layer 104 inside the tensile reinforcement layer 103 is an 80-120 mesh, 0.1-0.3 mm thick graphene-modified copper mesh. Graphene improves the conductivity and corrosion resistance of the copper mesh. The shielding layer 104 can shield external electromagnetic interference and prevent the cable's own electromagnetic signals from radiating outward, ensuring stable current transmission. The filling layer 107 inside the shielding layer 104 is a flexible insulating filler such as polypropylene rope or glass fiber rope, which fills the gap between the inner insulating sheath 105 and the shielding layer 104. It can offset the internal stress when the cable is bent or vibrated, and ensure the stability of the conductor core 106 position. The inner insulating sheath 105 inside the filling layer 107 is a cross-linked polyethylene layer with 0.1-0.3wt% graphene micro-flakes added, which tightly wraps the conductor core 106. It can isolate the conductor core 106 from the external structure to prevent leakage, and can also improve the heat resistance and mechanical strength with the help of graphene micro-flakes, avoiding the aging of the sheath caused by long-term current heating. The innermost conductor core 106 is made of copper and graphene composite wires twisted together. Copper ensures basic conductivity, and graphene optimizes conductivity by filling copper lattice defects and improving electron mobility. At the same time, the twisted structure combined with the high strength characteristics of graphene enhances the tensile strength of the conductor core 106 itself.

[0047] When the graphene tensile cable winding device winds up cable 1, it first rotates the handle 628 to drive the worm gear 627 to rotate. The worm gear 627 drives the worm wheel 626 to rotate the vertical threaded rod 625. With the threaded connection between the vertical threaded rod 625 and the first lifting sleeve 622, and the sliding connection between the second lifting sleeve 623 and the vertical rod 624, the rotation of the vertical threaded rod 625 drives the first lifting sleeve 622 to move upward to the highest position and stop. The first lifting sleeve 622 and the second lifting sleeve 623 drive the horizontal slide rod 621 to move upward synchronously. The upward movement of the horizontal slide rod 621 drives the housing 521 to move upward. Through the housing 521, the pressing component 52 and the opening and closing component 53 are driven. The transmission component 54 moves upward as a whole, thereby increasing the distance between the pressure roller 522 and the third pulley 514, making it easier to place the cable 1. At the same time, the second lifting sleeve 623 drives the actuating column 618 to move to the top of the inclined guide groove 612, thereby causing the side frame 611 to drive the side pressure plate 613 to move away from the side circular plate 412. Then the positioning block 614 moves away from the side circular plate 412. Subsequently, the operator passes one end of the cable 1 around the fourth pulley 515, the third pulley 514, the first pulley 512 and the second pulley 513 in sequence. Then, the operator passes one end of the cable 1 through the through hole 414 and extends it out, so that the extended part of the cable 1 bends downward and is located between the two positioning blocks 614.

[0048] Then, the handle 628 is rotated in the opposite direction, causing the first lifting sleeve 622 to move downward. The first lifting sleeve 622 drives the horizontal slide bar 621 and the second lifting sleeve 623 to move downward. The horizontal slide bar 621 drives the housing 521 to slide downward along the vertical connecting rod 516. The housing 521 drives the pressing component 52, the opening and closing component 53 and the transmission component 54 to move downward as a whole.

[0049] The drive wheel 544 is located directly above the fourth pulley 515. The housing 521 moves downward, and the drive wheel 544 contacts the upper surface of the cable 1 located on the fourth pulley 515. As the housing 521 moves further downward, the drive wheel 544 stops due to the resistance of the cable 1. The connecting frame 541 continues to move downward to compress the third spring 545. The vertical sliding rod 542 remains on the connecting frame 541 and slides vertically. Then, the housing 521 continues to move downward, driving the push wheel 535 to move downward synchronously. The push wheel 535 moves along the inclined guide 547 to the vertical guide 548. With the guidance of the inclined guide 547, the push wheel 535 drives the sliding frame 533 to compress the second spring 536. The sliding frame 533 slides along the second crossbar 532 to press the button of the self-reset button switch 534 until the push wheel 535 enters the vertical guide 548 from the inclined guide 547. Then, the self-reset button switch 534 is opened to power the device.

[0050] During the downward movement of the second lifting sleeve 623, the actuating column 618 is driven to move downward. The actuating column 618 moves from the top end of the inclined guide groove 612 to its bottom end. During this process, the actuating column 618 drives the side frame 611 to move closer to the support frame 2. The side frame 611 drives the side pressure plate 613 to move closer to the side circular plate 412 until the positioning block 614 abuts against the side wall of the side circular plate 412. Thus, the side pressure plate 613 and the side circular plate 412 work together to clamp and limit the section of cable 1 extending from the perforation 414. This ensures that one end of the cable 1 is clamped and will not fall off the winding roller 411 when the cable 1 is wound up. It also makes it easier to keep one end of the cable 1 fixed to the winding roller 411 when the cable 1 is wound up. The side pressure plate 613 is rotated in conjunction with the side frame 611. When the side circular plate 412 rotates, it drives the positioning block 614 and the side pressure plate 613 to rotate.

[0051] At this time, the pressure roller 522 presses on the upper surface of the cable 1 on the third pulley 514, and the lifting slider 523 can slide in the groove 525. When the pressure roller 522 presses on the cable 1, the first spring 524 is in a compressed state, so that the cable 1 can be better tightened when it is wound up, and the cable 1 is not too loose when it is wound up.

[0052] When the self-reset button switch 534 is turned on, the motor 413 drives the take-up roller 411 to rotate and take up the cable 1. At the same time, the motor 413 drives the drive synchronous pulley 424 to rotate. The drive synchronous pulley 424 drives the driven synchronous pulley 423 to rotate through the synchronous belt 425. The driven synchronous pulley 423 drives the reciprocating screw 421 to rotate. The reciprocating screw 421 drives the reciprocating screw nut 422 to reciprocate, thereby causing the reciprocating screw nut 422 to slide back and forth on the first crossbar 426. The reciprocating screw nut 422 drives the mounting bracket 511 to move back and forth, thereby causing the guide unit 5 to move back and forth. The housing 521 remains sliding back and forth along the crossbar 621, realizing the winding action of the cable 1. When the other end of the cable 1 is wound up until it is disengaged from the fourth pulley 515, at this time... The other end of cable 1 is close to the third pulley 514. Since the other end of cable 1 is disengaged from the fourth pulley 515, there is no resistance from cable 1 below the transmission wheel 544. The elastic potential energy of the third spring 545 is released, and the third spring 545 pushes the lifting frame 543 to move downward, thereby causing the guide block 546 to move downward until the push wheel 535 disengages from the vertical guide part 548. At this time, the elastic potential energy of the second spring 536 is released, pushing the sliding frame 533 to move away from the self-reset button switch 534. The push wheel 535 moves to the top of the inclined guide part 547, and the sliding frame 533 stops pressing the button of the self-reset button switch 534. The self-reset button switch 534 disconnects the circuit, the motor 413 stops working, and the winding action of cable 1 is completed.
