Description

Technical Field

[0001] This invention relates to the field of cable winding and unwinding technology, and more specifically to an automatic winding and unwinding reel for high-voltage cables and its method of use. Background Technology

[0002] High-voltage cables are cables that are made of one or more strands of conductors twisted together, resembling a rope. Each strand of conductor is insulated from the others and is usually twisted around a central wire. The entire outside of the cable is covered with a high-quality insulating layer to form an insulating space and prevent the cable from affecting changes in the external magnetic field during power transmission.

[0003] Currently, the transfer process of high-voltage cables uses a take-up and release reel as the main carrying tool. The take-up and release reel usually consists of a release reel, a base, and a transmission assembly. Because the old-style take-up and release reels are inefficient and lack cable management capabilities, the existing take-up and release reels also have a cable management device as an auxiliary tool. In use, one end of the cable is passed through the cable management device and fixed to the release reel. The motor is started, and the cable is gradually wound around the release reel under the drive of the motor. As the cable moves, the cable management device moves laterally back and forth under the drive of the cable, tightly fixing the cable to the release reel in sequence, avoiding the accumulation of cable and affecting subsequent use, so that the take-up and release reel has a better performance when taking up the cable.

[0004] However, with existing cable reels, the cable unwinding process is hampered by friction between each loop of cable. The reverse rotation of the motor alone cannot complete the cable unwinding task. When the motor rotates in the reverse direction, the cable doesn't extend from one side of the device; instead, it bulges under the influence of friction, increasing the gap between each loop and thus the overall diameter. Therefore, external tension is usually required as a guide during unwinding, with the motor's reverse rotation serving as an auxiliary tool. It's clear that current cable reels struggle to unwind independently. Furthermore, the cable length changes during unwinding after use, requiring readjustment of the motor's rotation time. Since the current operating environment cannot accommodate timely motor adjustments, personnel must manually shut off the motor after unwinding to prevent over-rotation. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an automatic take-up and unwinding reel for high-voltage cables and a method for using the same, so as to solve the problems existing in the background art.

[0006] This invention provides the following technical solution: an automatic cable reel for high-voltage cables and its usage method, comprising a stabilizing component, the stabilizing component including a supporting shell, movable frames installed on both sides of the supporting shell, a motor bracket fixedly connected to the top inside the supporting shell, a drive motor fixedly connected to one side of the motor bracket, rotating grooves opened on both sides inside the supporting shell, cable rollers installed inside the rotating grooves, a clamping groove opened on the front inside the supporting shell, a fastening component installed inside the clamping groove, a linkage component installed on the back of the fastening component, a tensioning component installed on the front of the fastening component, a connecting rod hinged to the top of the tensioning component, a one-way component hinged to the back of the connecting rod, two support frames fixedly connected on both sides of the connecting rod inside the supporting shell, a cable guiding component installed between the two support frames, and cable limiting components installed on both sides of the one-way component between the two support frames;

[0007] The fastening assembly includes a fastening box, with horizontal blocks installed on both sides inside the fastening box. An inclined slot is provided on the outer side of the horizontal block, and a rubber inclined plate is fixedly connected to the inner side of the horizontal block. The rubber inclined plate is made of rubber and has a 45-degree inclined angle during installation. The linkage assembly includes a wear-resistant ring, with extended side plates fixedly connected to both sides of the wear-resistant ring. A connecting block is fixedly connected to the top of the extended side plate, and the connecting block is movably connected to the connecting rod through a positioning pin. A reciprocating inclined block is fixedly connected to the front of the extended side plate, and an inclined block is fixedly connected to the inner side of the reciprocating inclined block. The inclined block is installed in the slot of the horizontal block, and a pushing inclined block is fixedly connected to the front of the reciprocating inclined block. The pushing inclined block is in the same position as the inclined slot on the inclined side plate.

[0008] Furthermore, the tensioning assembly includes a fastening ring, with beveled side plates fixedly connected to both sides of the fastening ring. A beveled groove is formed on the back of the beveled side plates. A clamping rod is movably connected to the top of the inner side of the fastening ring. Clamping springs are installed on both sides of the clamping rod. The inner diameter of the two fastening rings is smaller than the diameter of the cable. A push rod is fixedly connected to the back of the fastening ring. A through hole for the push rod is formed on the front of the rubber beveled plate. A sliding groove is formed on the front of the push rod in the fastening box.

[0009] Furthermore, an elastic component is installed inside the horizontal block, and the inclined slot on the outside of the horizontal block is the same size as the inner inclined block of the reciprocating inclined block.

[0010] Furthermore, the support frame includes two support plates, both of which are fixedly installed inside the support housing. A vertical plate is installed inside the support plate, and two spring assemblies are installed on the outer side of the vertical plate. A toothed plate is installed on the top of the vertical plate, and the toothed plate meshes with a fixed angle gear.

[0011] Furthermore, the cable guiding assembly includes a guide box, a rotating rod, and a rotating auxiliary rod. Edge contacts are fixedly connected to the top of both sides of the guide box, and electronic contacts are installed inside the edge contacts. An edge gear is fixedly connected to one side of the rotating rod, and the edge gear meshes with a linkage gear. The linkage gear is fixedly connected to one side of the roller shaft.

[0012] Furthermore, the rotating rod and the rotating auxiliary rod are provided with helical grooves, and the rotation directions of the grooves are opposite. A positioner is installed inside the guide box. After the linkage gear rotates one revolution, the guide box moves on the rotating rod by a distance equal to the width of a cable diameter.

[0013] Furthermore, the cable management limiting assembly includes two edge plates, one side of which is fixedly connected to a fixed angle gear, and a one-way roller shaft is movably connected between the two edge plates. The outer surface of the one-way roller shaft has two guide grooves and multiple arc-shaped grooves.

[0014] Furthermore, the unidirectional component includes a barrier plate and a rotating plate. Multiple arc-shaped parts are movably connected to the bottom of the barrier plate, and a drive shaft is fixedly connected to the front of the barrier plate. The position of the drive shaft is the same as the position of the guide groove. The bottom of the drive shaft is placed in the guide groove. A connector is installed on the front of the drive shaft, and the connector and the connecting rod are movably connected by a positioning pin.

[0015] Furthermore, the arc-shaped component is installed inside the arc groove at the bottom of the barrier plate, and the position of the arc-shaped component corresponds one-to-one with the position of the arc groove. The shape of the arc-shaped component is the same as that of the arc groove. A spring is installed inside the barrier plate at the top of the arc-shaped component.

[0016] The technical effects and advantages of this invention are as follows:

[0017] 1. The present invention, by providing a fastening component and a tensioning component, facilitates the fastening ring to clamp inward under the action of the clamping spring after the cable tail leaves the interior of the tensioning component during cable winding. The moving push rod pushes the rubber inclined plate, and the friction between the rubber inclined plate and the cable is used to fix the cable tail, preventing the cable from entering the inside of the reel.

[0018] 2. By incorporating a linkage component, this invention facilitates the application of inward pressure from the reciprocating inclined block to the horizontal block during cable retraction, thereby reducing the distance between the rubber inclined plate and the cable and increasing the friction between them. This also facilitates the forced opening of the fastening component by the reciprocating inclined block during cable release, reducing the friction generated when the cable exits the cable.

[0019] 3. The present invention, by providing a cable guiding component and a cable limiting component, facilitates the cable management work by reciprocating during cable take-up. At the same time, the cable limiting component applies a fixing force to the taken-up portion of the cable by rising in stages, preventing the cable from moving on the cable roller and affecting the cable's neatness. It also facilitates the cable limiting component to descend in stages under its own weight during cable release, so that the unidirectional roller shaft contacts the cable.

[0020] 4. By incorporating a unidirectional component, this invention facilitates the use of the linkage component to move the arc-shaped component into the arc-shaped groove during active cable feeding, thereby increasing the unidirectional fixing effect on the unidirectional roller shaft. This allows the cable to complete the cable feeding action only, while preventing reverse movement that could affect the feeding effect. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The automatic take-up and undo reel for high-voltage cables and its usage method involved in the present invention are not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Reference Figure 1-3 This invention provides an automatic cable reel for high-voltage cables and its usage method, including a stabilizing component 1. The stabilizing component 1 includes a supporting shell 101. A motor bracket 102 is fixedly connected to the top inside the supporting shell 101. A drive motor 10 is fixedly connected to one side of the motor bracket 102. Rotating grooves 103 are opened on both sides inside the supporting shell 101. Cable rollers 11 are installed inside the rotating grooves 103. A clamping groove 104 is opened on the front inside the supporting shell 101. A fastening component 2 is installed inside the clamping groove 104. A linkage component 3 is installed on the back of the fastening component 2. A tensioning component 4 is installed on the front of the fastening component 2. A connecting rod 5 is hinged to the top of the tensioning component 4. A one-way component 9 is hinged to the back of the connecting rod 5. Two support frames 6 are fixedly connected on both sides of the connecting rod 5 on the front inside the supporting shell 101. A cable guiding component 7 is installed between the two support frames 6. Cable limiting components 8 are installed between the two support frames 6 on both sides of the one-way component 9.

[0033] In this embodiment, it should be specifically noted that the main difference between this embodiment and the prior art is that the friction generated by the high-voltage cable during movement is used as an auxiliary means to achieve automatic protection of the coil under different length changes during cable winding and active wire release during wire release. Specifically, this is achieved by fastening component 2, linkage component 3, wire guiding component 7, and wire limiting component 8.

[0034] The above structure is the main structure of this embodiment, which solves the problems of difficulty in fixing excessive winding caused by changes in length during winding and the easy reverse rotation of coils on the rollers during active winding, which leads to bulging and increased gap between coils, resulting in increased diameter. The cable roller 11 is an existing structure, and the specific structure and connection method of the cable roller 11 will not be described in detail in this embodiment. In addition, the guide box 701 is also existing technology, so this application does not make detailed limitations.

[0035] Reference Figure 4-5 The fastening assembly 2 includes a fastening box 201. Horizontal blocks 203 are installed on both sides inside the fastening box 201. An inclined slot is provided on the outer side of each horizontal block 203. A rubber inclined plate 202 is fixedly connected to the inner side of each horizontal block 203. The rubber inclined plate 202 is made of rubber and has a 45-degree inclination angle during installation. The linkage assembly 3 includes a wear-resistant ring 301. Extended side plates 302 are fixedly connected to both sides of the wear-resistant ring 301. A connecting block 303 is fixedly connected to the top of each extended side plate 302. The connecting block 303 is movably connected to the connecting rod 5 via a positioning pin. A reciprocating inclined block 304 is fixedly connected to the front of the extended side plate 302. An inclined block is fixedly connected to the inner side of the reciprocating inclined block 304. The inclined block is installed in the slot of the horizontal block 203. A pusher block is fixedly connected, and the pusher block is in the same position as the inclined groove on the inclined side plate 402. The tension assembly 4 includes a fastening ring 401. An inclined side plate 402 is fixedly connected to both sides of the fastening ring 401. An inclined groove is opened on the back of the inclined side plate 402. A clamping rod 404 is movably connected to the top of the inner side of the fastening ring 401. A clamping spring 405 is installed on both sides of the clamping rod 404. When the clamping spring 405 is in normal condition, the inner diameter of the fastening ring 401 is smaller than the diameter of the cable. A pusher rod 403 is fixedly connected to the back of the fastening ring 401. A through hole for the pusher rod 403 is opened on the front of the rubber inclined plate 202. A sliding groove is opened on the front of the fastening box 201 located on the pusher rod 403. The pusher rod 403 slides left and right in the sliding groove under the control of the fastening ring 401.

[0036] In this embodiment, it should be specifically explained that: an elastic component is installed inside the horizontal block 203, and the inclined slot opened on the outside of the horizontal block 203 is the same size as the inner inclined block of the reciprocating inclined block 304. When the linkage component 3 moves to the front, the inclined block enters the slot, and the rubber inclined plate 202 moves outward under the action of the elastic component, moving away from the edge of the cable. When the linkage component 3 is on the back, the inclined block is located on the outer plane of the horizontal block 203, and the rubber inclined plate 202 is in the inner position. There is a gap between the rubber inclined plate 202 and the cable. When there is no cable in the center of the tension component 4, the inward movement of the push rod 403 causes the rubber inclined plate 202 to contact the cable and stop it. Movable frames 105 are installed on both sides of the support shell 101. The installation of the movable frames 105 is beneficial to the transfer of the take-up and unwinding reels.

[0037] Reference Figure 6-7 The support frame 6 includes two support plates 601, both of which are fixedly installed inside the support housing 101. A vertical plate 602 is installed inside each support plate 601. Two spring assemblies 603 are installed on the outer side of the vertical plate 602. A toothed plate is installed on the top of the vertical plate 602, meshing with a fixed-angle gear 802. Under normal conditions, the spring assemblies 603 push the vertical plate 602 to fix it to the inner wall, causing it to mesh with the fixed-angle gear 802, thereby fixing the angle of the edge plate 801. The cable management guide assembly 7 includes a guide box 701, a rotating rod 702, and a rotating pair. Edge contacts 704 are fixedly connected to the top of both sides of the rod 703 and the guide box 701. Electronic contacts are installed inside the edge contacts 704. When the electronic contacts contact the vertical plate 602, they activate the positioner to change the direction of movement of the guide box 701. An edge gear is fixedly connected to one side of the rotating rod 702. The edge gear meshes with the linkage gear 1102. The linkage gear 1102 is fixedly connected to one side of the roller shaft 1101. After the linkage gear 1102 rotates one revolution, the guide box 701 moves a distance equal to the width of a cable diameter on the rotating rod 702.

[0038] In this embodiment, it should be specifically noted that: the rotating rod 702 and the rotating auxiliary rod 703 are provided with helical toothed grooves, and the rotation directions of the two toothed grooves are opposite. A positioner is installed inside the guide box 701. The positioner is activated when the edge contact 704 contacts the support frame 6. The positioner changes the moving direction of the guide box 701 by moving the toothed plate inside the guide box 701 up and down to make contact with the rotating rod 702 or the rotating auxiliary rod 703. The installation method of the positioner inside the guide box 701 is prior art and is not limited in this application.

[0039] Reference Figure 8-9The cable management limiting assembly 8 includes two edge plates 801. A fixed angle gear 802 is fixedly connected to one side of the edge plate 801. A one-way roller shaft 803 is movably connected between the two edge plates 801. Two guide grooves 804 and multiple arc grooves 805 are opened on the outer surface of the one-way roller shaft 803. The one-way assembly 9 includes a barrier plate 901 and a rotating plate 904. Multiple arc-shaped parts 902 are movably connected to the bottom of the barrier plate 901. The positions of the arc-shaped parts 902 correspond one-to-one with the positions of the arc grooves 805. A drive shaft 903 is fixedly connected to the front of the barrier plate 901. The position of the drive shaft 903 is the same as the position of the guide groove 804. The bottom of the drive shaft 903 is placed in the guide groove 804. A connector is installed on the front of the drive shaft 903. The connector and the connecting rod 5 are movably connected by a positioning pin.

[0040] In this embodiment, it should be specifically explained that: the arc-shaped component 902 is installed inside the arc groove at the bottom of the barrier plate 901, and its shape is the same as that of the arc groove 805. A spring is installed inside the barrier plate 901 at the top of the arc-shaped component 902. In the winding state, the rotation direction of the one-way roller shaft 803 is clockwise. At this time, the one-way roller shaft 803, combined with the weight of the edge plate 801, applies force to the cable, increasing the cable management effect. During the unwinding process, the one-way roller shaft 803 rotates counterclockwise, and the barrier plate 901 covers the upper surface of the one-way roller shaft 803 under the pulling force of the connecting rod 5. When the arc-shaped component 902 coincides with the arc groove 805, the one-way roller shaft 803 in the counterclockwise rotation state pushes the arc-shaped component 902 to rise and retract into the barrier plate 901. The one-way roller shaft 803 in the clockwise direction stops rotating under the action of the arc-shaped component 902. During the unwinding process, the pressure is increased to ensure that the diameter does not change while avoiding the one-way roller shaft 803 from rotating in the opposite direction, which would cause a cable failure.

[0041] Working principle of the invention:

[0042] The main problem solved by this embodiment is: using the friction force generated by the high-voltage cable during movement as an auxiliary means to achieve automatic protection of the coil under different length changes during cable winding and protection of the coil during active winding process. This solves the problems of difficulty in fixing excessive winding caused by length changes during winding and easy reverse rotation of the coil on the roller during active winding, which leads to bulging and increased gap between coils, resulting in increased diameter.

[0043] The specific steps are as follows:

[0044] Reeling process: One end of the cable is passed through the inlet / outlet hole 106 and fixed to one side of the cable roller 11 with the wear-resistant ring 301. Under the rotation of the drive motor 10, the cable gradually winds around the cable roller 11. Since the tooth groove of the rotating rod 702 is the same as the diameter of the cable, the guide box 701 and the cable arrive at the same side of the cable roller 11 at the same time. At this time, the edge contact 704 contacts the vertical plate 602, the internal positioner of the guide box 701 is activated, the movement direction of the guide box 701 changes, the guide box 701 moves to the other side and repeats the above process many times. After the end of the cable reaches and enters the interior of the tension assembly 4, the fastening rings 401 on both sides move inward under the action of the clamping spring 405. The push rod 403 moves inward synchronously under the drive of the fastening ring 401 to apply pressure to the rubber inclined plate 202 so that it contacts the cable. The cable is clamped by the friction force generated by the inclined surface and the cable, so as to prevent the cable from continuing to move inward and causing excessive reeling, which will affect subsequent use.

[0045] Cable feeding process: The motor rotates in the reverse direction, causing the tail of the cable to exit from the inlet / outlet hole 106. Since the cable is installed inside the wear-resistant ring 301, the wear-resistant ring 301 moves forward under the action of friction when the cable moves. The reciprocating inclined block 304 uses the inclined surface opened in the inclined side plate 402 to push the tension component 4 to move to both sides. At the same time, the inner inclined block on the reciprocating inclined block 304 enters the slot from the outer plane of the horizontal block 203. The change in position causes the rubber inclined plate 202 to move to both sides away from the cable when it is exiting, avoiding contact and friction. Driven by the linkage component 3, the connecting rod 5 pulls the one-way component 9 so that the arc-shaped part 902 is located in the arc-shaped groove 805, preventing the arc-shaped groove 805 from rotating in the opposite direction under the action of the cable with the tendency to move in the opposite direction. At the same time, the pressure of the one-way roller 803 is used to prevent the gap between the cable coils from increasing. After the cable is laid out once, the guide box 701 reaches one side. The same control process of the cable guide component 7 on the support frame 6 causes the edge plate 801 to be lowered by one unit under its own weight, continuously applying a fixing force to the cable when it is laid out until the cable is laid out.

[0046] Secondly, it also solved the problem of cable management and securing during cable reeling;

[0047] During the winding process, after the guide box 701 and the cable reach the same side of the cable roller 11 synchronously, the vertical plate 602 moves outward under the action of the pushing force, the top toothed plate separates from the fixed angle gear 802, and the edge plate 801, which loses its fixed angle, contacts the cable surface under its own gravity. At this time, the continuous rotation of the cable causes the diameter of the cable coil to increase, and the edge plate 801 automatically moves upward one unit under the action of the cable so that the cable can continue to be wound.

[0048] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

6. A method of using an automatic take-up and undo reel for high-voltage cables according to any one of claims 1-5, characterized in that, Includes the following steps: S1: During the winding process, one end of the cable is passed through the inlet / outlet hole (106) and the wear-resistant ring (301) in sequence and fixed on one side of the cable roller (11). Under the rotation of the drive motor (10), the cable gradually winds around the cable roller (11). The guide box (701) arrives at the same side of the cable roller (11) synchronously with the cable. The edge contact (704) contacts the vertical plate (602). The internal transducer of the guide box (701) is activated, and the movement direction of the guide box (701) changes. S2: During the cable routing process, after the guide box (701) and the cable arrive at the same side of the cable roller (11) simultaneously, the vertical plate (602) moves outward under the action of the pushing force, the top toothed plate separates from the fixed angle gear (802), and the edge plate (801) that loses its fixed angle contacts the cable surface under its own gravity. At this time, the continuous rotation of the cable causes the diameter of the cable coil to increase. S3: During the protection process, the tail of the cable reaches and enters the interior of the tension assembly (4). At this time, the fastening rings (401) on both sides move inward under the action of the clamping spring (405), and the push rod (403) moves inward synchronously under the drive of the fastening ring (401) to apply pressure to the rubber inclined plate (202) so that it contacts the cable. The cable is clamped by the friction force generated between the inclined plate and the cable. S4: During the cable feeding process, the motor rotates in the opposite direction, causing the tail of the cable to exit from the inlet / outlet hole (106). The wear-resistant ring (301) moves forward under the action of friction when the cable moves. The reciprocating inclined block (304) uses the inclined surface opened in the inclined side plate (402) to push the tension component (4) to move to both sides. The inner inclined block on the reciprocating inclined block (304) enters the slot from the outer plane of the horizontal block (203). The change in position causes the rubber inclined plate (202) to move to both sides away from the cable when it is feeding.
