Therefore, features defined with "first," "second," "third," etc., may explicitly or implicitly include one or more of that feature. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0032] In the following description, specific details such as particular system structures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the present invention. However, those skilled in the art will understand that the present invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0033] For reference Figure 1 The present invention provides a cable reel winding and unwinding device, which mainly includes two support components 100; the reel of the cable reel assembly can be placed between the two support components 100 and supported by the two support components 100.

[0034] like Figure 1 As shown, any support assembly 100 may include a base 11 and an adjustment module 2 disposed above the base 11; the adjustment module 2 may include at least two adjustment rods 21 and an adjustment sleeve 22 mounted on the at least two adjustment rods 21. The adjustment sleeve 22 is provided with a support structure 222 located between the at least two adjustment rods 21; the support structure 222 can serve as a spool for supporting the cable reel assembly, and the two ends of the spool can be respectively placed at the support structures 222 of the two support assemblies 100. The support structure 222 includes two rotatably disposed rollers 223; the ends of the spool can be disposed between the two rollers 223 and in contact with the two rollers 223 to facilitate the rotation of the spool.

[0035] Understandably, traditional cable reel winding and unwinding devices use slots, such as V-shaped members, to support the cable reel assembly's spool. However, the friction between the slots and the spool makes it difficult for the spool to rotate, resulting in slow cable winding and unwinding speeds and requiring significant labor. The cable reel winding and unwinding device of this application utilizes rollers 223 to assist the spool's rotation, thereby increasing the speed of cable winding and unwinding, significantly improving work efficiency, and shortening the construction period.

[0036] Moreover, due to the wide variety of cable reel products, such as overhead bare wires and power cable reels, different types of cable reels vary in diameter, material, and flexibility. When these cable reels need to be frequently wound up and down during construction, problems such as cable reel damage and uneven winding and unwinding can easily occur. The cable reel winding and unwinding device of this application uses rollers 223 to assist the rotation of the reel shaft, which can effectively reduce the force on the cable reel during winding and unwinding, avoid damage to the cable reel, and improve the smoothness of winding and unwinding.

[0037] The central axis of each roller 223 is parallel to the axial direction of the spool, and the distance between two rollers 223 is less than the diameter of the end of the spool. This ensures that when the end of the spool is placed between the two rollers 223, the circumferential sides of the two rollers 223 are tangent to the circumferential sides of the end of the spool. At this time, the two rollers 223 can work together to lift the end of the spool and assist in its rotation. Simultaneously, because a portion of the end of the spool is embedded between the two rollers 223, the spool will not easily detach from between them, effectively preventing the spool from slipping during winding and / or transportation.

[0038] The adjusting sleeve 22 can be moved back and forth along the axial direction of the adjusting rod 21. (See reference...) Figure 2 The adjustment module 2 also includes a first positioning element 23 that positions the adjustment sleeve 22 at a certain height position of the adjustment rod 21.

[0039] Understandably, in traditional cable reel winding devices, the V-shaped component cannot be height-adjusted, thus only meeting the requirements for a small portion of cable reel sizes and not accommodating a wider range of sizes. However, in the cable reel winding device of this application, since the adjusting sleeve 22 can be height-adjusted, it can accommodate cable reel assemblies of different sizes.

[0040] For reference Figure 1 Each support assembly 100 may also include a lifting module 3 disposed below the adjusting sleeve 22 for adjusting the height position of the reel.

[0041] like Figure 1 As shown, the lifting module 3 may include a support base 31 installed at at least two adjusting rods 21 and a jack 32 disposed on top of the support base 31. The jack 32 is positioned below the end of the reel to lift or lower the reel. Understandably, conventional cable reel winding devices support the reel using V-shaped members, and since there is no position for the jack 32 to contact the reel, the cable reel can only be lifted or lowered using a hoist. However, in the cable reel winding device of this application, the end of the jack 32 can extend from the interval between two rollers 223, thus allowing for quick lifting and lowering of the entire cable reel assembly.

[0042] The support base 31 can be moved back and forth along the axial direction of the adjusting rod 21. (See reference...) Figure 2 The lifting module 3 also includes a second positioning element 33 that positions the support 31 at a certain height position of the adjusting rod 21.

[0043] The following describes the structure of the cable reel winding device of this application by defining the direction in which the two support components 100 are arranged at intervals as the first horizontal direction h1, and the horizontal direction perpendicular to the first horizontal direction h1 as the second horizontal direction h2; for details, please refer to Figure 1The directions shown. Understandably, the first horizontal direction h1 is the same as the axis of the spool; the two rollers 223 are arranged in the same direction as the second horizontal direction h2.

[0044] In some embodiments, please review Figure 1 The cable reel winding device may include a frame 1, which includes the aforementioned base 11, a top rod 12 disposed above the base 11, and a connecting rib 13 connecting the top rod 12 and the base 11. One end of any adjusting rod 21 of the adjusting module 2 may be connected to the base 11, and the other end may be connected to the top rod 12. Two sets of connecting ribs 13 are provided, respectively arranged on both sides of the adjusting module 2 along the second horizontal direction h2. Optionally, each set of connecting ribs 13 may include two diagonal tie ribs 131 inclined in the vertical direction. Each diagonal tie rib 131 includes a first end and a second end. The first ends of the two diagonal tie ribs 131 in the same set are connected to the same position on the top rod 12, and the second ends of the two diagonal tie ribs 131 are respectively connected to different positions on the base 11, so that there is a gap between the two second ends. With this arrangement, the two diagonal tie ribs 131 and the base 11 can form a triangular structure to improve the overall structural strength and support stability of the frame 1, effectively prevent the support assembly 100 from shaking or deforming during use, and withstand a certain degree of external impact, thereby preventing the cable reel assembly from tipping over. Further optionally, each set of connecting ribs 13 also includes at least one horizontal tie rib 132 connected between the two diagonal tie ribs 131 to improve the overall structural strength of the two diagonal tie ribs 131 in the same set.

[0045] Please refer to the following: Figure 3 The base 11 may include an annular base frame 111 and a plurality of connecting parts 112 disposed inside the base frame 111. The two ends of each connecting part 112 are respectively connected to the base frame 111, and the connecting parts 112 may be arranged at intervals or staggered.

[0046] The base 11 can be welded from high-strength I-beams and angle steel. The welding process adopts arc welding to ensure welding quality and strength, so as to ensure structural stability and meet the usage requirements of different working scenarios.

[0047] A pulley 14 may also be provided on the side of the base 11 away from the other support component 100 to provide a basis for moving the support component 100. Understandably, traditional cable reel winding devices are fixed; if the cable reel winding device needs to be moved, it can only be transported to a predetermined position by means of transport machinery or manual labor. However, this cable reel winding device, through the rollers 223, allows the entire device to be easily moved within the workplace, greatly improving work efficiency. Preferably, the pulley 14 can be made of high-strength rubber material, possessing good wear resistance and grip, enabling stable movement under different ground conditions.

[0048] For example, such as Figure 3 As shown, two solid rubber pulleys 14 are mounted on the side of the base 11 away from the other support assembly 100. The rubber pulleys 14 have good toughness and corrosion resistance. Correspondingly, the axle of the pulleys 14 is connected to the side of the base 11 through bearings (not shown) to ensure that the pulleys 14 rotate flexibly and to ensure that the support assembly 100 can move flexibly in the work area.

[0049] Revisit Figure 2 The adjustment module 2 may include two adjustment rods 21, which are arranged at intervals along the second horizontal direction h2. Correspondingly, the bottom frame 111 may have two connecting parts 112 arranged at intervals, and the two adjustment rods 21 can stand vertically on the top of the corresponding connecting parts 112. It should be noted that the adjustment module 2 is not limited to including only two adjustment rods 21, but may also include three or more adjustment rods 21, which may be arranged at intervals with a vertical axis as the center. Secondly, for the sake of brevity, the following description of this scheme will continue with the example of the adjustment module 2 including two adjustment rods 21.

[0050] like Figure 2 As shown, the adjusting sleeve 22 may include two first components 221, which may be cylindrical, and are configured to be fitted onto the adjusting rod 21 in a corresponding manner. The support structure 222 is configured to be fixed between the two first components 221.

[0051] In addition to the two rollers 223 mentioned above, the support structure 222 may also include two vertically arranged mounting plates 224, which are arranged opposite each other and spaced apart in the first horizontal direction h1. Two rollers (not shown) are installed between the two mounting plates 224, and the two rollers 223 are respectively sleeved on the two rollers.

[0052] Preferably, the top surface of any mounting plate 224 is provided with a recessed groove 225, and two rollers 223 are respectively located on opposite sides of the groove 225 in the second horizontal direction h2. A portion of the spool is configured to be embedded in the groove 225, which serves a protective function to prevent the spool from slipping. The radius of the groove 225 is between 80mm and 150mm, for example, 90mm, 100mm, 110mm, or 120mm, with a preferred radius of 110mm.

[0053] Optionally, the groove wall of the groove 225 can also serve as a support structure 222, acting as a support for the cable reel assembly's spool. It can be further noted that the curvature of the groove wall of the groove 225 and the contact area between the groove 225 and the spool can be optimized so that, while ensuring smooth rotation of the spool, the groove wall of the groove 225 and the roller 223 together provide sufficient support for the spool.

[0054] Continue to refer to Figure 2 The first positioning element 23 may include two first pins, each first pin being configured to be inserted into the corresponding position of the adjusting rod 21 below the adjusting sleeve, so as to position the adjusting sleeve 22 on the adjusting rod 21. Understandably, the first pins can engage the adjusting sleeve at a certain height position on the adjusting rod 21 to achieve height adjustment of the adjusting sleeve 22. Correspondingly, each adjusting rod 21 has multiple holes 211 spaced apart along its axial direction, and the multiple holes 211 between two adjusting rods 21 are arranged at the same height in a one-to-one correspondence; the two first pins can be inserted into two holes 211 at the same height, thereby limiting the adjusting sleeve 22 to the corresponding height position. It can be further noted that the first positioning element 23 is not limited to two first pins; it can also be a U-shaped element, with both ends of the U-shaped element inserted into two holes 211 at the same height.

[0055] Preferably, the first pin is threaded and is screwed into the hole 211 of the adjusting rod 21. Understandably, the screw connection has a self-locking function, which can ensure that the first pin is reliably inserted into the hole 211.

[0056] In some embodiments, the adjustment module 2 can be configured to have 5-15 adjustment positions, i.e., each adjustment rod 21 has 5-15 holes 211; for example, the adjustment positions can be 8, 10, or 12. The spacing between two adjacent holes 211 can be between 50-200mm; for example, the spacing between two adjacent holes 211 can be 80mm, 100mm, 120mm, 150mm, or 180mm. In a specific embodiment, the adjustment module 2 can be configured to have 10 adjustment positions, i.e., each adjustment rod 21 has 10 holes 211, and the spacing between adjacent holes 211 can be 100mm; this configuration can meet the usage requirements of cable reel assemblies with radii between 200mm and 1200mm.

[0057] like Figure 2 As shown, a first chain 24 may also be provided between the first positioning member 23 and the adjusting sleeve 22 to fix the first positioning member 23 to the adjusting sleeve 22. Understandably, limiting the position of the first positioning member 23 within a certain range of the adjusting sleeve 22 can ensure that the first positioning member 23 is readily available and prevent the first positioning member 23 from being lost.

[0058] Continue to refer to Figure 2 The support base 31 may include two second components 311 and a support plate 312 fixed between the two second components 311. The second components 311 may be cylindrical and are configured to be fitted onto the adjusting rod 21 in a corresponding manner. The support plate 312 is horizontally arranged to support the jack 32. The extension end of the jack 32 is disposed between two rollers 223, and this end extends upward from the gap between the two rollers 223 and abuts against the end of the reel.

[0059] The second positioning element 33 may include two second pins, each configured to be inserted into a position below the support 31 corresponding to the adjusting rod 21, to position the support 31 on the adjusting rod 21. For example, the two second pins may be inserted into two holes 211 at the same height, thereby limiting the support 31 to the corresponding height position.

[0060] A second chain 34 may also be provided between the second positioning element 33 and the support base 31 to fix the second positioning element 33 to the support base 31. Understandably, limiting the position of the second positioning element 33 within a certain range of the support base 31 can ensure that the second positioning element 33 is readily available and prevent the second positioning element 33 from being lost.

[0061] The specific operation process of this cable reel winding and unwinding device is as follows:

[0062] First, the support assembly 100 is tilted to the side, and the support assembly 100 is moved to the target position using the pulley 14; understandably, a cable reel assembly is placed at the target position; after the two support assemblies 100 are moved to the target positions respectively, the two ends of the reel of the cable reel assembly are respectively located between the two corresponding adjusting rods 21.

[0063] Then, according to the size of the cable reel assembly, adjust the height of the support base 31 so that the jack 32 can contact the reel; then, the jack 32 lifts the cable reel assembly, and the lifted cable reel assembly is at least 50mm away from the plane (ground); the support base 31 is adjusted by moving the support base 31 up and down. After it is moved into place, the second pin is inserted into the hole 211 below the adjusting rod 21. At this time, the second pin supports the support base 31.

[0064] At the same time, adjust the height of the adjusting sleeve 22 so that the spool abuts against the two rollers 223 of the adjusting sleeve 22; the method of adjusting the adjusting sleeve 22 is the same as that of adjusting the support seat 31, and will not be described in detail here. Then, release the jack 32, and the spool is fully supported by the adjusting sleeve 22.

[0065] It should be noted that the installation process for the cable reel assembly has been described in detail above. If disassembly is required, please refer to the reverse of the installation steps; it will not be repeated here.

[0066] In summary, the cable reel winding and unwinding device of this application is a mobile device, including two support components 100 that cooperate with each other and adopt a gantry structure. Each support component 100 mainly includes a frame 1, an adjustment module 2, a lifting module 3, and pulleys 14. The adjustment module 2 includes two adjustment rods 21 installed on the frame 1, and a set of rollers 223 arranged between the two adjustment rods 21 to provide a support base for the reel of the cable reel assembly.

[0067] This device has at least the following beneficial effects:

[0068] (1) High adaptability: The position of the cable reel assembly can be adjusted by adjusting module 2 as needed to accommodate cable reels of different sizes, significantly improving the flexibility and adaptability of cable reel winding and unwinding. The high-precision setting of adjusting rod 21 allows the height of the cable reel assembly to be accurately adjusted to the appropriate position to meet the needs of various working scenarios.

[0069] (2) Reduced labor intensity: The design of roller 223 can effectively reduce the labor intensity of operators and improve work efficiency. Operators only need to install the cable reel assembly on this cable reel device to flexibly reel in and out cables.

[0070] (3) Enhanced safety: The design of the adjusting sleeve 22 and the first positioning component 23 can ensure the stability of the cable reel during winding and unwinding, and prevent it from slipping accidentally. At the same time, the overall structure of the frame 1 of this device is sturdy and durable, and can withstand a certain amount of external impact, protecting the cable reel and the safety of the operator.

[0071] (4) Low equipment cost: This device only requires jack 32 to lift and lower the cable reel assembly, eliminating the need for complex and expensive hydraulic or mechanical devices, thus reducing equipment costs. Jack 32 can be a manual hydraulic jack 32 or an electric jack 32, which is simple to operate and inexpensive. Compared with traditional hydraulic or mechanical lifting devices, the cost of this device is greatly reduced.

[0072] (5) High flexibility: This device is small in size and simple in structure, making it suitable for work sites with limited space resources, such as offshore platforms and narrow passageways. The compact design of the device enables it to move and be operated in confined spaces, and the design of pulley 14 also ensures the mobility of the device, meeting the needs of different work scenarios.

[0073] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model.
