Description

Technical Field

[0001] This invention relates to the field of cable tensioner technology, and more particularly to a planetary gear driven flat ribbon cable tensioner and its method of use. Background Technology

[0002] During emergency cable repairs, large areas of cables in the cable trenches are damaged, requiring the rapid clearing and restoration of a large number of cables. Cables must be laid in layers according to design requirements; signal, control, low-voltage power, and high-voltage cables cannot be mixed in the same layer. Therefore, during cable laying, they must be arranged in layers on the cable tray in a specific order. Simultaneously, cables should be kept straight during laying, with a bending radius greater than 15 times the cable's outer diameter to prevent damage at bends. Therefore, the most important aspect of cable laying is the rational planning and arrangement of cables. Due to the large number and weight of cables, some cables need to be pulled up and re-laid during the cable management process. Currently, a double-hook tensioner is used for this task, but the existing tensioner has a small hook at the bottom, requiring additional rope to bind the cable and hang it on the hook. Using a hand lever to pull the cable up is inefficient, and the current tensioner also suffers from low efficiency when lowering cables and is not well-suited for this purpose.

[0003] For emergency repair projects involving cable laying, the time requirements are high, and efficiency is often the key to restoring production. Therefore, this invention improves the efficiency of this process. Thus, to address this issue, this application provides a planetary gear driven flat belt cable tensioner to meet the requirements. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that current cable tensioners are inefficient and inconvenient to operate when lifting and lowering cables.

[0005] The technical solution of the present invention: a planetary gear driven flat-belt cable tensioner includes a cylindrical shell. A power input component, a sling winding component, and an anti-reverse component are disposed on the inner side of the cylindrical shell. The power input component includes an internal gear ring fixedly connected to the inner wall of the cylindrical shell. Multiple planetary gears mesh with the inner side of the internal gear ring, and a sun gear meshes between the multiple planetary gears. A first handle is fixedly connected to one side of the sun gear and rotatably connected inside the cylindrical shell. Connecting posts are fixedly connected to the sides of the multiple planetary gears away from the first handle. Planetary carriers are sleeved on the outer sides of the multiple connecting posts. A shaft is fixedly connected to one side of the planetary carrier. The sling winding component and the anti-reverse component are both connected to the shaft. A connecting shaft is rotatably connected inside the cylindrical shell, and a transmission wheel is fixedly connected to one end of the connecting shaft.

[0006] Optionally, the sling winding assembly includes a partition plate fixedly connected to the inner wall of the cylindrical shell, a shaft rotatably connected to the outside of the partition plate, a winding wheel fixedly connected to the outside of the shaft plate, and the winding wheel being disposed on the inside of the partition plate.

[0007] Optionally, a sling is wound around the outer side of the reel, and a plurality of connection holes are provided on one side of the sling, with a hook fixedly connected to the bottom end of the sling.

[0008] Optionally, the anti-reverse assembly includes a ratchet fixedly connected to one end of the shaft, a limiting side plate fixedly connected to one side of the partition, and a limiting slide pin slidably connected to the inner side of the limiting side plate.

[0009] Optionally, one end of the limiting slide pin is fixedly connected to a stop member, and the number of the stop members is set to two. The two stop members are distributed in a circumferential array on both sides of the ratchet, and both stop members are engaged with the ratchet.

[0010] Optionally, the top and bottom of the anti-reverse components on both sides are fixedly connected with side connecting arms, the inner sides of the side connecting arms on both sides are slidably connected with limit crossbars, and a return spring is fixedly connected between the side connecting arms on both sides.

[0011] Optionally, a transmission plate is fixedly connected to one side of the side connecting arm, and a transmission push plate is slidably connected to one side of the partition, with the transmission push plate disposed inside the transmission plate.

[0012] Optionally, the inner side of the transmission push plate is threaded with a double helical shaft, one end of which is fixedly connected to a rotating shaft, which is rotatably connected inside the cylindrical shell, and one side of the side connecting arm is fixedly connected to a transmission protrusion.

[0013] Optionally, a second handle is fixedly connected to the end of the connecting shaft away from the transmission wheel.

[0014] In summary, this application includes at least one of the following beneficial technical effects: By using a power input component to reduce speed and increase torque, the lifting difficulty can be significantly reduced when a large number of cables need to be lifted temporarily, thereby increasing the lifting efficiency of the cables. Moreover, the lifting process can be completed by a single person, thus reducing the use of manpower. It significantly increases the contact area with the cable, which can significantly reduce the pressure on the cable during lifting, thereby protecting the cable. When bundling the cable, simply wrap the cable with the sling and connect the hook to the connection hole. This bundling method is simple and convenient, does not require the use of additional rope, and makes the bundling of the cable more efficient. The anti-reverse component significantly improves the convenience of cable lowering, enabling multiple short-distance cable lowerings. This not only reduces the lowering speed and ensures cable safety but also allows for precise control of the lowering accuracy and height. Lowering the cable only requires a one-way rotation of the second handle, and the drive wheel requires minimal power, thus significantly improving the efficiency of cable lowering and reducing the intensity of manual labor. Furthermore, the anti-reverse release operation is simple and convenient, reducing the difficulty of actual operation and facilitating use. Attached Figure Description

[0017] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0018] The components of the embodiments of the invention described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0019] Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, 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 invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] Example 1: As Figures 1-6 As shown, the planetary gear driven flat-belt cable tensioner includes a cylindrical shell 1. The top of the cylindrical shell 1 can be equipped with components such as hooks for fixing the entire shell 1. The inner side of the cylindrical shell 1 is provided with a power input component, a belt winding component, and an anti-reverse component. The power input component includes an internal gear ring 2 fixedly connected to the inner wall of the cylindrical shell 1. Multiple planetary gears 3 are meshed on the inner side of the internal gear ring 2. A sun gear 4 meshes between the multiple planetary gears 3. A first handle 5 is fixedly connected to one side of the sun gear 4. The first handle 5 is rotatably connected to the inside of the cylindrical shell 1. A connecting post 6 is fixedly connected to the side of each of the multiple planetary gears 3 away from the first handle 5. A planet carrier 7 is sleeved on the outer side of the multiple connecting posts 6. A shaft 8 is fixedly connected to one side of the planet carrier 7. The belt winding component and the anti-reverse component are both connected to the shaft 8.

[0023] In this embodiment, the cylindrical shell 1 is fixed above the position where the cable needs to be lifted. Since the internal gear ring 2 is fixed to the inner wall of the cylindrical shell 1, the rotation of the sun gear 4 by turning the first handle 5 serves as the power input, causing the planetary gear 3 to rotate on its own axis and revolve around the sun gear 4. This causes the planetary carrier 7 to rotate, and simultaneously drives the shaft 8 to rotate. Since both the sling winding assembly and the anti-reverse assembly are connected to the shaft 8, the planetary carrier 7 serves as the power output, causing the sling winding assembly to lift the cable. At this time, the rotational speed of the planetary carrier 7 is lower than that of the sun gear 4, and since the input torque acts on the sun gear 4, while the internal gear ring 2 provides the reaction force, the output torque of the planetary carrier 7 is greater than the input torque. This allows for speed reduction and torque increase through the power input assembly. Therefore, when it is necessary to temporarily lift a large number of cables, the lifting difficulty can be significantly reduced, thereby increasing the lifting efficiency of the cables. Moreover, the lifting process can be completed by a single person, thus reducing the use of manpower.

[0024] Example 2: The sling winding assembly includes a partition 9 fixedly connected to the inner wall of the cylindrical shell 1, a shaft 8 rotatably connected to the outside of the partition 9, a winding wheel 10 fixedly connected to the outside of the shaft 8, the winding wheel 10 being located inside the partition 9, a sling 11 being wound around the outside of the winding wheel 10, the sling 11 being an aramid flat strip, the partition 9 limiting the winding wheel 10 and the sling 11, a plurality of connecting holes 12 being opened on one side of the sling 11, a metal protective ring being fixedly sleeved inside the connecting hole 12 for protection and to improve strength, and a hook 13 being fixedly connected to the bottom end of the sling 11.

[0025] In this embodiment, when fixing and lifting the cable, the anti-reverse limit is released by the anti-reverse component, and the sling 11 is pulled out, passing through the bottom of the cable, so that the hook 13 is connected to the connection hole 12 in the appropriate position to realize the cable bundling. Thus, it is not necessary to use additional ropes to fix the cable. Moreover, the sling 11 can significantly increase the contact area with the cable, and can significantly reduce the pressure on the cable during the lifting process, thereby protecting the cable. When bundling the cable, the sling 11 is simply wrapped around the cable and the hook 13 is connected to the connection hole 12. This bundling method is simple and convenient, and the bundling of the cable is more efficient.

[0026] Example 3: The anti-reverse assembly includes a ratchet 14 fixedly connected to one end of the shaft 8, a limiting side plate 15 fixedly connected to one side of the partition 9, a limiting slide post 16 slidably connected to the inner side of the limiting side plate 15, a stop member 17 fixedly connected to one end of the limiting slide post 16, and two stop members 17 arranged in a circumferential array on both sides of the ratchet 14. Both stop members 17 are engaged with the ratchet 14. The bottom of the position where the stop member 17 engages with the ratchet 14 is sloped. Side connecting arms 18 are fixedly connected to the top and bottom of both side stop members 17. A limiting crossbar 19 is slidably connected to the inner side of both side connecting arms 18. The limiting crossbar 19 limits the side connecting arms 18 on both sides. A return spring 20 is fixedly connected between the two side connecting arms 18.

[0027] In this embodiment, the ratchet 14 is fixed to the shaft 8 and rotates with it. When the cable is lifted by winding the sling 11, as... Figure 2 As shown, the winding wheel 10 needs to rotate clockwise, and the ratchet 14 rotates clockwise at the same time. At this time, the ratchet 14 is not limited by the anti-reverse member 17 and can push the anti-reverse members 17 on both sides to the sides. When the anti-reverse members 17 on both sides move to the sides, the limiting slide 16 slides on the inner side of the limiting side plate 15 at the same time, and the return spring 20 is stretched. The contraction of the return spring 20 can make the anti-reverse members 17 on both sides return to their original position and engage with the ratchet 14 in time. Conversely, when the ratchet 14 rotates counterclockwise, the ratchet 14 will be blocked and limited by the anti-reverse member 17, so it cannot rotate in the opposite direction. This achieves the purpose of preventing the winding wheel 10 from rotating in reverse and ensures the convenience of actual use.

[0028] Example 4: A transmission protrusion 25 is fixedly connected to one side of the side connecting arm 18, and a connecting shaft 26 is rotatably connected inside the circular cylindrical shell 1. A transmission wheel 27 is fixedly connected to one end of the connecting shaft 26, and a second handle 28 is fixedly connected to the end of the connecting shaft 26 away from the transmission wheel 27.

[0029] In this embodiment, when the cable needs to be lowered, the second handle 28 is rotated in any direction, causing the connecting shaft 26 to drive the transmission wheel 27 to rotate. As the transmission wheel 27 rotates, the protruding part of the transmission wheel 27 gradually contacts the transmission protrusions 25 on both sides. Figure 5As shown, the transmission wheel 27 pushes the transmission protrusions 25 on both sides, causing them to move outward. This allows the side connecting arms 18 on both sides to move away from each other, thus separating the stop 17 from the ratchet 14 and releasing the ratchet 14 from its limit. At this time, the sling 11 drives the reel 10 to rotate under the influence of the cable's weight, thereby lowering the cable. Because the protrusions of the transmission wheel 27 and the transmission protrusions 25 are relatively small, when the transmission wheel 27 rotates, it pushes the transmission protrusions 25 on both sides and quickly passes over the inner protrusion of the transmission protrusions 25. At this time, the side connecting arms 18 on both sides... When the return spring 20 contracts, arm 18 will reset and engage with ratchet 14 again, thus stopping the cable from being lowered. By continuously rotating the transmission wheel 27, the cable can be lowered multiple times over short distances. This not only reduces the cable lowering speed and ensures the safety of the cable lowering, but also allows for precise control of the cable lowering accuracy and flexible control of the cable lowering height. Furthermore, the cable lowering only requires a one-way rotation of the second handle 28, and the transmission wheel 27 requires relatively little rotational force. This significantly improves the efficiency of cable lowering and reduces the intensity of manual labor.

[0030] Example 5: A transmission plate 21 is fixedly connected to one side of the side connecting arm 18, and a transmission push plate 22 is slidably connected to one side of the partition plate 9. The transmission push plate 22 is located inside the transmission plate 21. A double helical shaft 23 is threadedly connected to the inner side of the transmission push plate 22. Two threads with opposite directions are provided at both ends of the double helical shaft 23, so that the transmission push plates 22 on both sides can approach or move away from each other. A rotating shaft 24 is fixedly connected to one end of the double helical shaft 23. The rotating shaft 24 is rotatably connected inside the circular cylindrical shell 1.

[0031] In this embodiment, when the anti-reverse limit of the anti-reverse component needs to be released, the double helical shaft 23 is rotated by rotating the upper and lower shafts 24, thereby causing the transmission push plates 22 on both sides to move away from each other, and simultaneously pushing the transmission plates 21 on both sides to move away from each other. The transmission plates 21 drive the side connecting arms 18 to move synchronously, thereby allowing the anti-reverse stop 17 on both sides to separate from the ratchet 14. At this time, the anti-reverse stop 17 is limited by the transmission push plate 22, thereby keeping the anti-reverse stop 17 in a rotation completely separated from the ratchet 14, realizing the release of the anti-reverse limit of the winding wheel 10, so that the winding wheel 10 can continuously unwind the sling 11. This setting can realize the release of the anti-reverse limit through simple operation, further simplifying the operation and facilitating practical use.

[0032] A method for using a planetary gear driven flat ribbon cable tensioner is also disclosed, including the following steps: S1: According to actual usage requirements, fix the hook or bracket of the fixed circular shell 1 to the circular shell 1, and ensure that the circular shell 1 is fixed at a suitable height at the top of the part of the cable that needs to be lifted; S2: Release the anti-reverse limit of the anti-reverse component, allowing the sling winding component to rotate freely, thereby enabling the cable to be fixed by the sling winding component; S3: Reset the anti-reverse component to restore its anti-reverse function, and rotate the first handle 5 to reduce speed and increase torque through the power input component, thereby driving the sling winding component to efficiently lift and raise the cable; S4: During cable lowering, the intermittent failure of the anti-reverse component allows the cable to descend multiple short distances under its own weight, ensuring both cable lowering efficiency and safety.

[0033] The above specific embodiments are merely optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
