Description

Technical Field

[0001] This invention relates to the field of cable winding technology, and in particular to a cable winding roller drive device and a cable winding device. Background Technology

[0002] Wires and cables are wire products used for power, electrical, and related transmission applications. They mainly include bare wires, building wires, power cables for electrical equipment, cross-linked cables, and communication optical cables. In a broad sense, wires and cables are also simply referred to as cables; in a narrow sense, cables refer specifically to insulated cables. During cable production, cables are often wound up for easier storage. Traditionally, a manual crank is used to drive the winding roller, or a motor shaft is connected to the winding roller to rotate it and wind up the cable. This method requires installing the winding roller before each winding operation and disassembling it afterward, making the process cumbersome and affecting cable winding efficiency.

[0003] In related technologies, to improve winding efficiency, a device has been proposed that can evenly wind cables onto the surface of a winding roller. This device, through the combined action of a circulating winding device and a tightening device, improves winding efficiency and stability. However, in practical applications, this solution is only suitable for winding rollers whose dimensions match the device; existing winding rollers are not applicable, leading to a significant increase in operating costs and impacting economic efficiency.

[0037] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

[0038] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0039] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0040] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0041] like Figures 1-4 As shown, the cable winding device provided by the present invention includes a winding roller 9 and a cable winding roller drive device, which drives the winding roller 9 to rotate. The cable winding roller drive device can be disposed on the periphery of the winding roller 9 and is in contact with the circumferential outer surface of the winding roller 9. The cable winding roller drive device includes a mounting base 1, a drive assembly 2, two sets of support assemblies 3, and a friction assembly 4. The drive assembly 2 is disposed on the top of the mounting base 1, and the two sets of support assemblies 3 are connected to the top of the mounting base 1 and are spaced apart; the friction assembly 4 is connected between the two sets of support assemblies 3, and the drive assembly 2 can drive the friction assembly 4 to rotate relative to the support assemblies 3. The friction assembly 4 is configured to abut against the circumferential outer surface of the winding roller 9 and drive the winding roller 9 to rotate through friction.

[0042] In practice, the take-up roller 9 is mounted on the support base 8. Since the cable take-up roller drive device and the take-up roller 9 are separate, there is no need to move the support base 8 when performing the cable winding operation. The cable take-up roller drive device only needs to be installed on the periphery of the take-up roller 9, and the friction component 4 needs to be in contact with the circumferential outer surface of the take-up roller 9. Thus, the friction component 4 rotates under the drive of the drive component 2, thereby pressing against the circumferential outer surface of the take-up roller 9. Through friction, the take-up roller 9 rotates, achieving the winding of the cable by the take-up roller 9.

[0043] The cable winding roller drive device provided in this embodiment of the invention does not require installation and disassembly of the winding roller 9. The cable winding roller drive device can be installed on the periphery of the winding roller 9. In this way, the cable winding roller drive device can be used for winding rollers 9 of various sizes, which helps to expand the application range of the cable winding roller drive device. Furthermore, when it is necessary to replace the winding roller 9 for the next cable winding, the cable winding roller drive device can be moved directly to the side of the winding roller 9 without cable, making the operation more convenient, which helps to improve the cable winding efficiency and increase the actual economic benefits.

[0044] like Figures 1-6 As shown, in some embodiments, the support assembly 3 includes a swing rod 31 and a telescopic rod 34. The top end of the swing rod 31 is connected to the friction assembly 4, and the bottom end of the swing rod 31 is rotatably connected to the mounting base 1. The top end of the telescopic rod 34 is rotatably connected to the swing rod 31, and the bottom end of the telescopic rod 34 is rotatably connected to the mounting base 1. The relative fixed angle between the friction assembly 4 and the swing rod 31 is adjustable. The swing rod 31 can be connected to the friction assembly 4 via a connecting seat 32, or it can be directly connected to the friction assembly 4; no specific limitation is made here.

[0045] By configuring the support assembly 3 as a combination of a swing rod 31 and a telescopic rod 34, when the telescopic rod 34 extends or retracts, it can drive the swing rod 31 to swing relative to the mounting base 1, thereby changing the position and height of the friction assembly 4. Furthermore, the relative fixed angle between the friction assembly 4 and the swing rod 31 is adjustable. In other words, in practical applications, the adjustable design of the support assembly 3 allows the friction assembly 4 to be better adapted to winding rollers 9 of different diameters through different positions and angles.

[0046] In specific implementation, such as Figure 1 and Figure 7As shown, when the telescopic rod 34 retracts, it causes the swing rod 31 to swing away from the take-up roller 9, at which point the vertical height of the friction assembly 4 decreases. Conversely, when the telescopic rod 34 extends, it causes the swing rod 31 to swing closer to the take-up roller 9, increasing the vertical height of the friction assembly 4. The angle between the friction assembly 4 and the swing rod 31 remains relatively fixed during the rotation of the take-up roller 9. After adjusting the friction assembly 4 to different height positions by retracting or extending the telescopic rod 34, the angle of the friction assembly 4 relative to the swing rod 31 can be adjusted so that the friction assembly 4 can contact the circumferential outer surface of the take-up roller 9 containing the cable to be wound. After the angle adjustment, the friction assembly 4 is fixed relative to the swing rod 31 again to ensure smooth operation of the friction assembly 4 when driving the take-up roller 9. Figure 1 and Figure 7 As shown, when the cable winding roller drive device of the present invention drives winding rollers 9 of different diameters to rotate, the height position and setting angle of the friction component 4 are different to ensure that the driving force can be smoothly transmitted to winding rollers 9 of different diameters.

[0047] In this embodiment of the invention, the bottom end of the swing rod 31 is rotatably connected to the mounting base 1 via the first connecting seat 33, the top end of the telescopic rod 34 is rotatably connected to the outer circumferential surface of the swing rod 31 via the second connecting seat 36, and the bottom end of the telescopic rod 34 is rotatably connected to the mounting base 1 via the third connecting seat 38.

[0048] In addition, the telescopic rod 34 is a rotating telescopic structure. A threaded section 35 is provided at the top of the telescopic rod 34. The rotating part at the bottom of the telescopic rod 34 is rotatably connected to the third connecting seat 38 through the fourth connecting seat 37. The third connecting seat 38 is fixedly connected to the mounting base 1. The fourth connecting seat 37 and the third connecting seat 38 are rotatably connected. The rotating part on the telescopic rod 34 can rotate around its own central axis based on the fourth connecting seat 37. During adjustment, it is only necessary to rotate the rotating part to make the rotating part rotate around its own central axis, so that the threaded section 35 can be threadedly engaged with the rotating part, and the length of the telescopic rod 34 can be increased or decreased.

[0049] In other embodiments, the telescopic rod 34 can also be configured as a nested telescopic structure, that is, the telescopic rod 34 may include multiple telescopic sections, and both ends of the telescopic rod 34 are rotatably connected to the mounting base 1 and the swing rod 31 through two bases, respectively. The two bases are fixedly connected to the mounting base 1 and the swing rod 31, respectively. Taking two telescopic sections as an example, the first telescopic section is configured to extend into or out of the cavity inside the second telescopic section. When the first telescopic section extends into the second telescopic section, the overall length of the telescopic rod 34 decreases; when the first telescopic section extends out of the second telescopic section, the overall length of the telescopic rod 34 increases.

[0050] like Figures 1-5 As shown, in some embodiments, the friction assembly 4 includes two friction wheels 44, a first transmission member 45, a rotating shaft 43, and a connecting plate 41 connected to the support assembly 3; three rotating shafts 43 are arranged between the two connecting plates 41 in a triangular distribution, the two friction wheels 44 are respectively fixedly sleeved on two of the rotating shafts 43, the first transmission member 45 is fixedly sleeved on the other rotating shaft 43, the drive assembly 2 can drive the first transmission member 45 to rotate, the first transmission member 45 can drive the two friction wheels 44 to rotate, and the two friction wheels 44 are configured to abut against the circumferential outer surface of the take-up roller 9.

[0051] With this arrangement, two rotating friction wheels 44 simultaneously contact the take-up roller 9, increasing the contact area between the friction assembly 4 and the take-up roller 9. Furthermore, the two rotating friction wheels 44 are spaced apart, allowing them to rub against different positions on the take-up roller 9, which helps improve the stability of the take-up roller 9 when it rotates to wind up the cable.

[0052] Of course, in other embodiments, the number of friction wheels 44 can also be set to one. For example, when the size of the take-up roller 9 is small or the required rotational force is small, the number of corresponding rotating shafts 43 is also reduced to two. One rotating shaft 43 is fixedly fitted with a friction wheel 44, and the other rotating shaft 43 is fixedly fitted with a first transmission member 45. At this time, it is only necessary to ensure that the friction wheel 44 can drive the take-up roller 9 to rotate. The specific number can be determined according to the actual situation.

[0053] In this embodiment of the invention, each of the two connecting plates 41 is fixedly connected with a collar 42, and each collar 42 is rotatably connected to a corresponding collar 42 on the other connecting plate 41 with a rotating shaft 43. The surfaces of the three rotating shafts 43 are fitted with a first synchronous belt 46. That is, the drive assembly 2 drives the first transmission component 45 and its corresponding rotating shaft 43 to rotate, causing the first synchronous belt 46 fitted on the surface of the rotating shaft 43 to rotate. The rotation of the first synchronous belt 46 then drives the other two rotating shafts 43 to rotate, ultimately causing the two friction wheels 44 fixedly fitted on the other two rotating shafts 43 to rotate and press against the circumferential outer surface of the take-up roller 9.

[0054] Furthermore, two first synchronous belts 46 are provided, respectively located at opposite ends of the rotating shafts 43, with each first synchronous belt 46 surrounding the periphery of the three rotating shafts 43. In this way, the rotation of the two first synchronous belts 46 can balance the forces at both ends of each rotating shaft 43, thereby enabling the contact surface between the friction wheel 44 and the winding roller 9 to transmit force evenly, which helps to make the rotation of the winding roller 9 more stable.

[0055] In other embodiments, holes for the rotating shaft 43 to pass through can be directly opened on the connecting plate 41, which is convenient and quick; the first synchronous belt 46 can also be omitted, and the friction wheel 44 can be driven to rotate by the first transmission member 45 directly contacting the friction wheel 44. The specific configuration can be determined according to the actual situation.

[0056] like Figure 2 and Figure 8 As shown, in some embodiments, the drive assembly 2 includes a motor 21, a movable seat 26, a second synchronous belt 22, and a second transmission member 24. The movable seat 26 is slidable relative to the mounting base 1. The motor 21 is mounted on the movable seat 26. Two support members 25 are arranged opposite each other on the top of the movable seat 26. A main shaft 23 is rotatably mounted between the two support members 25. The output end of the motor 21 is connected to the main shaft 23 via the second synchronous belt 22. The second transmission member 24 is mounted between the two support members 25 and fixedly sleeved on the main shaft 23. The second transmission member 24 can cooperate with the friction assembly 4 to drive the friction assembly 4 to rotate.

[0057] In practice, firstly, the sliding seat 26 makes the second transmission component 24 contact the first transmission component 45 of the friction assembly 4 to ensure a transmission connection between the second transmission component 24 and the first transmission component 45. Secondly, the motor 21 is turned on, the second synchronous belt 22 starts to rotate, and drives the main shaft 23 to rotate. At this time, the second transmission component 24, which is fixedly sleeved on the main shaft 23, starts to rotate, thereby driving the first transmission component 45 to rotate synchronously. As mentioned above, the rotation of the first transmission component 45 causes the first synchronous belt 46 sleeved on the surface of the rotating shaft 43 to rotate. The rotation of the first synchronous belt 46 then drives the other two rotating shafts 43 to rotate, ultimately causing the two friction wheels 44 fixedly sleeved on the other two rotating shafts 43 to rotate and press against the circumferential outer surface of the winding roller 9. The winding roller 9 then begins to wind up the cable.

[0058] With this configuration, even when the position and angle of the friction component 4 change, the lateral movement of the movable seat 26 ensures that the second transmission component 24 can always maintain contact with the first transmission component 45 and apply driving force to it. This prevents the cable winding roller drive from failing to operate due to the second transmission component 24 and the first transmission component 45 not making contact, thus improving the reliability of the winding device. Furthermore, by using the electric motor 21 as the power source, manual winding via a rocker arm or similar means is eliminated, achieving automatic winding functionality.

[0059] In this embodiment of the invention, the first transmission member 45 and the second transmission member 24 are configured as two meshing gears, but this is not limited to this. In other embodiments, the first transmission member 45 and the second transmission member 24 can also be configured as two friction wheels that transmit power through friction, depending on the actual situation.

[0060] like Figure 8 As shown, in some embodiments, the mounting base 1 has a mounting groove 11, the movable seat 26 is disposed in the mounting groove 11, the groove wall of the mounting groove 11 has a sliding groove 13, the sliding groove 13 extends along the sliding direction of the movable seat 26, and a slider 28 is fixedly connected to the side of the movable seat 26 near the sliding groove 13, the slider 28 is configured to slide in cooperation with the sliding groove 13.

[0061] With this configuration, the movable seat 26 does not occupy additional space beyond the mounting base 1, thereby saving the overall space occupied by the cable winding roller drive device and making the overall structure of the device more compact.

[0062] The method of enabling the sliding seat 26 to slide is not limited to the cooperation between the sliding groove 13 and the slider 28 in the embodiments of the present invention. For example, it can also be set as a guide rail and pulley. A guide rail extending along the sliding direction of the sliding seat 26 is provided on the groove wall of the mounting groove 11, and one or more pulleys are fixedly provided on the side of the sliding seat 26 near the guide rail. The translation of the sliding seat 26 relative to the mounting base 1 is achieved by the movement of the pulleys in the guide rail. The specific settings can be determined according to the actual situation.

[0063] like Figure 8 As shown, in some embodiments, a first threaded rod 12 is rotatably mounted in the mounting groove 11. The first threaded rod 12 passes through the movable seat 26 along the sliding direction of the movable seat 26. A movable sleeve 27 is fixedly fitted inside the movable seat 26, and the first threaded rod 12 passes through the movable sleeve 27. The first threaded rod 12 and the movable sleeve 27 are threadedly connected. That is, when the first threaded rod 12 rotates, it can drive the movable sleeve 27 to move along the length direction of the first threaded rod 12. Since the movable sleeve 27 is fixedly connected inside the movable seat 26, the rotation of the first threaded rod 12 indirectly drives the movable seat 26 to translate. In other embodiments, the movable sleeve 27 can also be integrally formed with the movable seat 26.

[0064] The movement of the movable seat 26 is achieved by setting the first threaded rod 12, which has a simple structure. The cooperation between the first threaded rod 12 and the movable sleeve 27 can play a certain guiding role for the movable seat 26, so that the movable seat 26 always moves along the length direction of the first threaded rod 12 during the movement, thus avoiding the movement trajectory of the movable seat 26 from deviating and affecting the operation of the friction assembly 4.

[0065] Of course, in other embodiments, the translation of the movable seat 26 can also be driven in other ways. For example, the movable seat 26 can be driven to perform reciprocating translational motion by a mechanism such as a cylinder.

[0066] like Figure 8As shown, in some embodiments, one end of the first threaded rod 12 is provided with a third transmission member 14 and a fourth transmission member 15 that mesh with each other. The third transmission member 14 is fixedly connected to one end of the first threaded rod 12, and the fourth transmission member 15 can drive the third transmission member 14 to rotate.

[0067] With this configuration, the first threaded rod 12 can be driven to rotate through the meshing transmission of the third transmission component 14 and the fourth transmission component 15. This meshing transmission method effectively ensures the smoothness and accuracy of the rotation of the first threaded rod 12.

[0068] In this embodiment of the invention, the third transmission member 14 and the fourth transmission member 15 are bevel gears, but are not limited to this; for example, they can also be spur gears or bevel gears. In other embodiments, the transmission method between the third transmission member 14 and the fourth transmission member 15 can also be set as friction transmission, for example, both the third transmission member 14 and the fourth transmission member 15 can be set as friction wheels. The specific method can be determined according to the actual situation.

[0069] like Figure 8 As shown, in some embodiments, the top of the mounting base 1 is provided with a mounting cover 17, which covers the fourth transmission member 15. The top of the fourth transmission member 15 is fixedly connected with an operating member 16, which protrudes from the top of the mounting cover 17 and can drive the fourth transmission member 15 to rotate.

[0070] By setting the mounting cover 17, external impurities such as dust can be prevented from falling in and affecting the operating accuracy of the fourth transmission component 15. The setting of the operating component 16 facilitates user operation. Users can control the transmission between the third transmission component 14 and the fourth transmission component 15 by rotating the operating component 16.

[0071] In this embodiment of the invention, the operating element 16 is an operating turntable, but it is not limited to this. For example, the operating element 16 can also be set as an operating handle, etc.

[0072] like Figure 1 and Figure 2 As shown, in some embodiments, the mounting base 1 has a mounting hole 5 for the insertion rod 7 to pass through, and the mounting base 1 can be fixed to the ground by the insertion rod 7.

[0073] During use, the cable winding roller 9 will exert a certain thrust on the cable winding roller drive device, which will cause the bottom of the mounting base 1 to slide. Therefore, by inserting the plug rod 7 into the mounting hole 5 and extending the plug rod 7 deep into the ground, it can be ensured that the cable winding roller drive device will not move during use, which is beneficial to improving the stability of the cable winding roller drive device.

[0074] like Figure 9As shown, in some embodiments, a cable winding roller drive device is provided on each of the opposite sides of the winding roller 9, and a connecting part 6 is provided on each of the two mounting bases 1. The two connecting parts 6 are located on the side close to the winding roller 9, and a connecting rope 61 is provided between the two connecting parts 6.

[0075] By setting two cable winding roller drive devices, the opposite sides of the winding roller 9 can be driven simultaneously. The simultaneous force on both sides of the winding roller 9 increases its stability during rotation. Furthermore, during the winding process, the winding roller 9 generates a certain thrust on the cable winding device, which can cause the bottom of the mounting base 1 to slide. At this time, by using a connecting rope 61 to connect the connection parts 6 of the two cable winding roller drive devices, the movement of the cable winding roller drive devices away from the winding roller 9 can be effectively prevented.

[0076] The number of connecting ropes 61 can be one or two, as in this embodiment of the invention. Figure 9 Another connecting rope 61 is provided at a symmetrical position along the width direction of the mounting base 1 to improve the limiting ability of the connecting rope 61 on the two cable winding roller drive devices.

[0077] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention.
