Description

Technical Field

[0001] This utility model relates to the field of communication operation equipment technology, and in particular to an auxiliary unwinding device for cable reels. Background Technology

[0002] Cables are characterized by internal conductivity and external insulation. During storage and transportation, to improve space utilization, cables are typically wound together into cylindrical cable reels. During winding, a central support shaft can be used to wind the cable, or it can be omitted. When cable laying is required, the wound cable reels are unwound.

[0003] In related technologies, when unwinding cable reels without a central support shaft, the cables wound together within the reel are prone to loosening and knotting. Furthermore, as the unwinding length of the cable reel increases, both the axial height and radial thickness of the reel decrease, further exacerbating the problem of loosening and knotting of the wound cables, significantly reducing the efficiency of cable unwinding and consequently reducing cable laying efficiency.

[0004] Therefore, there is an urgent need to invent an auxiliary unwinding device for cable reels to solve the above problems. Utility Model Content

[0018] The first abutment is fixedly connected to the second nut. A portion of the first abutment is located inside the hollow cavity of the cable reel. The first abutment located inside the hollow cavity of the cable reel can abut against the inner wall of the cable reel.

[0019] As an optional solution, the first radial drive structure includes:

[0020] Operations unit; and

[0021] The first bevel gear is fixedly connected to the operating part and is rotatably mounted on the first axial clamp. The rotation axis of the first bevel gear is parallel to the axial direction of the cable reel. The first abutment structure also includes a second bevel gear, which is fixedly connected to the second lead screw. The rotation axis of the second bevel gear coincides with the central axis of the second lead screw. The second bevel gear meshes with the first bevel gear for transmission.

[0022] As an optional solution, the first radial clamping assembly has multiple sets of the first abutment structures, with the output ends of the multiple sets of the first abutment structures spaced apart axially within the hollow cavity of the cable reel.

Combined with the relative and opposite movements of the first axial clamping plate and the second axial clamping plate along the axial direction of the cable reel, when it is necessary to put the cable reel into the axial clamping space, the first axial clamping plate and the second axial clamping plate move opposite each other, increasing the size of the axial clamping space to facilitate the placement of the cable reel into the axial clamping space. When it is necessary to clamp and fix the cable reel in the axial clamping space, the first axial clamping plate and the second axial clamping plate move towards each other, decreasing the size of the axial clamping space and allowing the first axial clamping plate and the second axial clamping plate to clamp together. This device holds and fixes the cable reel, achieving axial clamping and positioning of the cable reel.

Furthermore, this cable reel auxiliary unwinding device, by clamping and positioning the cable reel from both axial and radial directions, can adapt to cable reels with different axial and radial dimensions, achieving clamping and positioning of cable reels of different specifications, thus improving applicability.

[0042] 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 present 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, not the entire structure.

[0043] In the description of this utility model, 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 utility model based on the specific circumstances.

[0044] 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.

[0045] 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 this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0046] During cable storage and transportation, to improve space utilization, cables are typically wound together into cylindrical cable reels. During winding, a central support shaft can be used to wind the cables, or it can be omitted. When cable laying is required, the wound cable reels are unwound. When unwinding cable reels without a central support shaft, the wound cables are prone to loosening and knotting. Furthermore, as the unwinding length of the cable reel increases, the axial height and radial thickness of the reel decrease, further exacerbating the problem of loosening and knotting the wound cables, significantly reducing unwinding efficiency and consequently cable laying efficiency.

[0047] To solve the above problems, such as Figure 1As shown, this embodiment provides an auxiliary unwinding device for cable reels. The auxiliary unwinding device includes an axial clamping mechanism 100 and a radial clamping mechanism 200. The axial clamping mechanism 100 includes a first axial clamping plate 110 and a second axial clamping plate 120 arranged opposite each other along the axial direction of the cable reel. An axial clamping space for clamping the cable reel is formed between the first axial clamping plate 110 and the second axial clamping plate 120. The first axial clamping plate 110 and the second axial clamping plate 120 can move towards each other or away from each other along the axial direction of the cable reel. The radial clamping mechanism 200 includes a first radial clamping assembly 210 and a second radial clamping assembly 220. The output end of the first radial clamping assembly 210 can move radially along the cable reel and abut against the inner wall of the cable reel. The output end of the second radial clamping assembly 220 can move radially along the cable reel and abut against the outer peripheral wall of the cable reel.

[0048] This cable reel auxiliary unwinding device, by setting a first axial clamping plate 110 and a second axial clamping plate 120 within the axial clamping mechanism 100, allows the first axial clamping plate 110 and the second axial clamping plate 120 to be arranged opposite each other along the axial direction of the cable reel, thus forming an axial clamping space for clamping the cable reel between the first axial clamping plate 110 and the second axial clamping plate 120. Combined with the relative and opposite movements of the first axial clamping plate 110 and the second axial clamping plate 120 along the axial direction of the cable reel, when it is necessary to place the cable reel into the axial clamping space, the first axial clamping plate 110 and the second axial clamping plate 120 move opposite to each other, increasing the size of the axial clamping space to facilitate the placement of the cable reel. When it is necessary to clamp and fix the cable reel in the axial clamping space, the first axial clamping plate 110 and the second axial clamping plate 120 move towards each other, decreasing the size of the axial clamping space and reducing the distance between the first axial clamping plate 110 and the second axial clamping plate 120. The plates 120 together clamp and fix the cable reel, achieving axial clamping and positioning of the cable reel. By splitting the radial clamping mechanism 200 into a first radial clamping component 210 and a second radial clamping component 220, the first radial clamping component 210 moves radially along the cable reel and abuts against the inner wall of the cable reel, and the second radial clamping component 220 moves radially along the cable reel and abuts against the outer peripheral wall of the cable reel. The first radial clamping component 210 and the second radial clamping component 220 clamp and position the cable reel from the inner and outer sides of the cable reel respectively, achieving radial clamping and fixing of the cable reel. Combined with the axial clamping mechanism 100 for axial clamping and fixing of the cable reel, the cable reel is clamped and positioned from the axial and radial directions of the cable reel, solving the problem of loosening and knotting of the cable during unwinding, improving the unwinding efficiency of the cable reel, and improving the cable laying efficiency. In addition, the cable reel auxiliary unwinding device can clamp and position the cable reel from the axial and radial directions respectively, and can also adapt to cable reels with different axial and radial dimensions, so as to realize the clamping and positioning of cable reels of different specifications and improve applicability.

[0049] It should be noted that in this embodiment, the axial direction of the cable reel is vertical. In other embodiments, the specific direction of the axial direction of the cable reel can be adjusted according to actual needs; this embodiment does not impose a specific limitation. Furthermore, the cable reel auxiliary unwinding device of this embodiment also includes a base 300. A first axial clamping plate 110 within the axial clamping mechanism 100 is disposed above a second axial clamping plate 120, and the second axial clamping plate 120 is rotatably mounted on the base 300. The base 300 has an extension 310 extending horizontally, and a radial clamping mechanism 200 is mounted on the extension 310. In addition, in this embodiment, the cable is a power cable.

[0050] As an optional solution, such as Figure 2As shown, the axial clamping mechanism 100 also includes a first axial drive structure 130, wherein the first axial drive structure 130 includes a first lead screw 131 and a first nut 132. The first lead screw 131 extends along the axial direction of the cable reel, and the first nut 132 is sleeved on the axial outer periphery of the first lead screw 131 and threadedly engaged with the first lead screw 131. One axial end of the first lead screw 131 is fixedly connected to a second axial clamping plate 120, and the first axial clamping plate 110 is fixedly connected to the first nut 132. By setting a first lead screw 131 extending along the axial direction of the cable reel and a first nut 132 sleeved on the outer axial circumference of the first lead screw 131 and threadedly engaged with the first lead screw 131, one axial end of the first lead screw 131 is fixedly connected to the second axial clamping plate 120, and the first axial clamping plate 110 is fixedly connected to the first nut 132. When the first nut 132 moves relative to the first lead screw 131 along the axial direction of the first lead screw 131, it can drive the first axial clamping plate 110 to move relative to the first lead screw 131 along the axial direction of the first lead screw 131, thereby achieving the purpose of the first axial clamping plate 110 and the second axial clamping plate 120 moving towards each other or away from each other along the axial direction of the cable reel.

[0051] It should be noted that, in this embodiment, the axial center of the first lead screw 131 and the center of the second axial clamp 120 are located in the same straight line, so that the cable reel is clamped at the center of the first axial clamp 110 and the center of the second axial clamp 120, thereby optimizing the clamping position of the second axial clamp 120 and the first axial clamp 110 on the cable reel and ensuring the clamping stability of the first axial clamp 110 and the second axial clamp 120 on the cable reel.

[0052] Combination Figure 3 and Figure 4The specific structure of the first radial clamping assembly 210 is described below. The first radial clamping assembly 210 includes a first radial driving structure 211 and a first abutting structure 212. The first radial driving structure 211 is installed at the first axial clamping plate 110. The first abutting structure 212 is connected to the output end of the first radial driving structure 211. The output end of the first abutting structure 212 is located in the hollow inner cavity of the cable reel. The first radial driving structure 211 can drive the output end of the first abutting structure 212 to move radially along the cable reel. The output end of the first abutting structure 212 can abut against the inner wall of the cable reel. By setting a first radial drive structure 211 at the first axial clamping plate 110, connecting the first abutting structure 212 to the output end of the first radial drive structure 211, and placing the output end of the first abutting structure 212 in the hollow inner cavity of the cable reel, the output end of the first abutting structure 212 is driven by the first radial drive structure 211 to move radially along the cable reel, thereby driving the output end of the first abutting structure 212 to abut against the inner wall of the cable reel, achieving the purpose of abutting and positioning the cable reel from inside the cable reel along the radial direction of the cable reel.

[0053] Optionally, the first abutting structure 212 includes a second lead screw 2122, a second nut 2123, and a first abutting member 2124. The second lead screw 2122 extends radially along the cable reel assembly. The first radial drive structure 211 can drive the second lead screw 2122 to rotate around the axial direction of the second lead screw 2122. The second nut 2123 is sleeved on the axial outer periphery of the second lead screw 2122 and threadedly engaged with the second lead screw 2122. The first abutting member 2124 is fixedly connected to the second nut 2123. A portion of the first abutting member 2124 is located within the hollow inner cavity of the cable reel assembly. The first abutting member 2124 located within the hollow inner cavity of the cable reel assembly can abut against the inner wall of the cable reel assembly. When the first abutment member 2124 needs to be driven to radially abut against the cable reel from the inside of the cable reel, the first radial drive structure 211 drives the second lead screw 2122 to rotate. The second nut 2123, driven by the thread, moves along the axial direction of the second lead screw 2122, that is, along the radial direction of the cable reel, thereby causing the first abutment member 2124 to move radially along the cable reel until the portion of the first abutment member 2124 located within the hollow cavity of the cable reel abuts against the inner wall of the cable reel. It should be noted that, in this embodiment, as... Figure 2 As shown, a guide groove 111 is provided on the first axial clamping plate 110. The guide groove 111 extends radially along the cable reel, and the first abutment 2124 slides within the guide groove 111.

[0054] In addition, the first abutment 2124 extends along the axial direction of the cable reel and can be stretched or contracted along the axial direction of the cable reel. One axial end of the first abutment 2124 is fixedly connected to the second nut 2123, and the other axial end of the first abutment 2124 abuts against the second axial clamp 120. By extending the first abutment 2124 along the axial direction of the cable reel, the axial movement of the first abutment 2124 is fixedly connected to the second nut 2123. The other axial end of the first abutment 2124 abuts against the second axial clamp 120. Combined with the fact that the first abutment 2124 can be stretched or contracted along the axial direction of the cable reel, the first abutment 2124 can always abut against the second axial clamp 120. When the first abutment 2124 abuts against the inner wall of the cable reel, it can not only maximize the contact area with the cable reel along the axial direction, but also ensure the uniformity of the contact between the first abutment 2124 and the inner wall of the cable reel along the axial direction.

[0055] In one alternative embodiment, the first radial drive structure 211 includes an operating part 2112 and a first bevel gear 2111. The first bevel gear 2111 is fixedly connected to the operating part 2112 and is rotatably mounted on the first axial clamping plate 110. The operating part 2112 is sleeved on the outer periphery of the first nut 132 and is rotatably connected to the first nut 132. The rotation axis of the first bevel gear 2111 is parallel to the axial direction of the cable reel. The first abutment structure 212 also includes a second bevel gear 2121. The second bevel gear 2121 is fixedly connected to the second lead screw 2122, and the rotation axis of the second bevel gear 2121 coincides with the central axis of the second lead screw 2122. The second bevel gear 2121 meshes with the first bevel gear 2111 for transmission. By providing a first bevel gear 2111 with a rotating shaft parallel to the axial direction of the cable reel in the first radial drive structure 211, and a second bevel gear 2121 with a rotating shaft parallel to the radial direction of the cable reel in the first abutment structure 212, and fixing the first bevel gear 2111 to the operating part 2112 rotatably mounted on the outer periphery of the first nut 132, and fixing the second bevel gear 2121 to the second lead screw 2122, the operating part 2112 can rotate around the axial direction of the cable reel, and the rotating shaft of the second bevel gear 2121 coincides with the central axis of the second lead screw 2122. By utilizing the meshing transmission of the first bevel gear 2111 and the second bevel gear 2121, the power of the operating part 2112 rotating around the axial direction of the cable reel can be converted into the power of the second lead screw 2122 rotating around the axis of the second lead screw 2122, thereby changing the direction of power transmission and improving the structural compactness of the cable reel auxiliary unwinding device. It should be noted that, in this embodiment, the rotational direction in which the operating unit 2112 drives the first abutment member 2124 to move radially inward is the same as the rotational direction in which the first nut 132 moves downward relative to the first lead screw 131. In other embodiments, the rotational direction in which the operating unit 2112 drives the first abutment member 2124 to move radially inward may be opposite to the rotational direction in which the first nut 132 moves downward relative to the first lead screw 131; this embodiment does not impose a specific limitation.

[0056] To further improve the clamping effect of the first radial clamping assembly 210 on the cable reel, the first radial clamping assembly 210 has multiple sets of first abutment structures 212. The output ends of the multiple sets of first abutment structures 212 are spaced apart axially around the cable reel within the hollow cavity of the cable reel. The first radial drive structure 211 can synchronously drive the output ends of all the first abutment structures 212 to move radially along the cable reel. It should be noted that in this embodiment, the first radial clamping assembly 210 has four sets of first abutment structures 212, which are equally spaced axially around the cable reel. The first bevel gear 2111 in the first radial drive structure 211 simultaneously meshes with the second bevel gear 2121 in the four sets of first abutment structures 212 to achieve synchronous drive of the four sets of first abutment structures 212. In other embodiments, the specific number of sets of first abutment structures 212 in the first radial clamping assembly 210 can be arbitrarily adjusted according to actual needs; this embodiment does not impose a specific limitation.

[0057] As an optional solution, such as Figure 5 As shown, the second radial clamping assembly 220 includes a second abutment structure 223 and a second radial drive structure 221. The second radial drive structure 221 is mounted on the extension 310 of the base 300, and the second abutment structure 223 is located outside the outer peripheral wall of the cable reel. The output end of the second radial drive structure 221 is connected to the second abutment structure 223, and the second radial drive structure 221 is used to drive the second abutment structure 223 to move radially along the cable reel. By arranging the second abutment structure 223 on the outer side of the cable reel and connecting the second abutment structure 223 to the output end of the second radial drive structure 221, the second abutment structure 223 is driven by the second radial drive structure 221 to move radially along the cable reel, achieving the effect of the second abutment structure 223 abutting against the radial outer peripheral wall of the cable reel, thereby securing the cable reel radially from the outside of the cable reel. It should be noted that, in this embodiment, the radial clamping mechanism 200 has two sets of second radial clamping components 220. The two sets of second radial clamping components 220 are disposed at opposite ends of the axial clamping space along the radial direction of the cable reel, and the two sets of second radial clamping components 220 abut against the outer peripheral wall of the cable reel. In other embodiments, the specific number of sets of second radial clamping components 220 can be adjusted according to actual needs, and this embodiment does not impose a specific limitation.

[0058] Optionally, the second radial drive structure 221 includes a first elastic element 2211, which extends radially along the cable reel. The axial ends of the first elastic element 2211 are fixedly connected to the outer extension 310 and the second abutment structure 223, respectively. When the first elastic element 2211 is in a compressed state, it can drive the second abutment structure 223 to move towards the cable reel in the radial direction under its own elastic force, thereby driving the second abutment structure 223 to abut against the outer peripheral wall of the cable reel. It should be noted that in this embodiment, the first elastic element 2211 is a spring. Springs have a simple structure, are easy to assemble and disassemble, and have a good driving effect.

[0059] To further improve the driving effect of the first elastic member 2211 on the second abutment structure 223, the second radial driving structure 221 also includes a first guide member 2212. The axial direction of the first guide member 2212 is parallel to the axial direction of the first elastic member 2211. The first elastic member 2211 is sleeved on the outer axial periphery of the first guide member 2212. The first guide member 2212 movably passes through the extension portion 310 along the axial direction of the first guide member 2212 and is fixedly connected to the second abutment structure 223. The movement of the first guide member 2212 relative to the extension portion 310 provides guidance for the movement of the second abutment structure 223. It should be noted that, in this embodiment, as... Figure 5 As shown, the first guide member 2212 is a bolt. The extension portion 310 has a clearance through hole 311 extending radially along the cable reel. The bolt shank portion moves from the side of the extension portion 310 away from the first elastic member 2211, passes through the clearance through hole 311, and extends into the first elastic member 2211, so that the first elastic member 2211 is sleeved on the outer periphery of the bolt shank, and finally the bolt shank is fixedly connected to the second abutment structure 223.

[0060] Furthermore, in this embodiment, the second radial clamping assembly 220 has two sets of second radial driving structures 221. The two sets of second radial driving structures 221 are arranged at intervals along the axial direction of the cable reel. The two sets of second radial driving structures 221 jointly drive the second abutment structure 223 to move radially along the cable reel, thereby further improving the driving effect on the second abutment structure 223. In other embodiments, the specific number of sets of second radial driving structures 221 can be adaptively adjusted according to actual needs; this embodiment does not impose a specific limitation.

[0061] In an alternative embodiment, the second radial clamping assembly 220 further includes a second axial drive structure 222, wherein the second abutment structure 223 includes a second abutment member 2231 and a third abutment member 2232 movably connected along the axial direction of the cable reel, both the second abutment member 2231 and the third abutment member 2232 being able to abut against the outer peripheral wall of the cable reel, the output end of the second radial drive structure 221 being connected to the third abutment member 2232, and the second axial drive structure 222 being able to drive the second abutment member 2231 to move relative to the third abutment member 2232. By splitting the second abutting structure 223 into a second abutting member 2231 and a third abutting member 2232 that are movably connected along the axial direction of the cable reel, and by combining the second axial driving structure 222 to drive the second abutting member 2231 to move relative to the third abutting member 2232, the contact area between the second abutting structure 223 and the cable reel along the axial direction can be adjusted, so that the second abutting structure 223 and the cable reel along the axial direction can fully contact each other.

[0062] It should be noted that, in this embodiment, the second abutment 2231 is located at the end of the third abutment 2232 along the axial direction of the cable reel, close to the first axial clamp 110, and the third abutment 2232 abuts against the second axial clamp 120. The second axial drive structure 222 drives the second abutment 2231 to move relative to the third abutment 2232 towards the first axial clamp 110 and abut against the first axial clamp 110, thereby ensuring the abutment effect on the cable reel. It can be understood that the specific structure of the second axial drive structure 222 is the same as that of the second radial drive structure 221. The second axial drive structure 222 includes a second elastic member 2221 and a second guide member 2222. The difference between the second axial drive structure 222 and the second radial drive structure 221 lies only in their arrangement position and driving direction. For the sake of brevity, the specific structure of the second axial drive structure 222 will not be described in detail here.

[0063] To further reduce the friction between the second abutment 2231 and the first axial clamping plate 110, and between the third abutment 2232 and the second axial clamping plate 120, in this embodiment, a first ball bearing 22311 is provided at one end of the second abutment 2231 near the first axial clamping plate 110, and the first ball bearing 22311 rolls against the first axial clamping plate 110; a second ball bearing 22321 is provided at one end of the third abutment 2232 near the second axial clamping plate 120, and the second ball bearing 22321 rolls against the second axial clamping plate 120.

[0064] Furthermore, in this embodiment, to reduce friction between the third abutment 2232 and the cable reel, a first roller 22322 is provided on the side of the third abutment 2232 near the cable reel. The first roller 22322 can roll and abut against the cable reel around its axial direction. In other embodiments, a second roller can also be provided on the side of the second abutment 2231 near the cable reel, so that the second roller can roll and abut against the cable reel around its axial direction. This embodiment does not impose a specific limitation.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
