DETAILED DESCRIPTION

[0023] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. Note that the relative arrangement, numerical expressions, and numerical values of the components and steps set forth in these embodiments are not limiting to the scope of the present application unless otherwise specifically stated.

[0024] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way limiting to the scope of the application and its applications or uses.

[0025] Techniques, methods, and devices known to those of ordinary skill in the relevant art can not be discussed in detail herein, but should be considered as part of the specification, where appropriate.

[0026] In all examples shown and discussed herein, any specific values should be interpreted as merely illustrative and not as a limitation. Thus, other examples of the exemplary embodiments can have different values.

[0027] As Figures 1-5 shown, it comprises a base plate 1 connectable with external mobile devices and a driving motor 2 fixedly connected on the base plate 1 through a motor base, and the output end of the driving motor 2 is fixedly connected with a first mounting seat 3 for placing a cable reel.

[0028] Here, the core benefit of the base plate 1 is that it can be connected with external mobile devices, such as engineering vehicles or trolleys, through bolts or hook structures, further improving the overall mobility of the device, adapting to the needs of cross-regional transfer of cable reels in power construction, engineering construction, and other scenarios; at the same time, as the basic bearing structure of the entire device, the base plate 1 can provide a stable mounting platform for the driving motor 2, the first mounting seat 3, the rotating rod 5, and other components, avoiding vibration deviation during equipment operation due to unstable foundation, thereby ensuring the stability of cable winding and unwinding operations.

[0029] Further, the driving motor 2 can provide continuous and stable automatic power output, replacing the traditional manual dragging operation, not only greatly reducing the labor intensity of the construction personnel, but also ensuring the uniformity of the cable winding and unwinding speed through precise speed control, effectively avoiding the uneven cable tension caused by the force being too large or too small during manual operation. In addition, the driving motor 2 is directly fixedly connected with the first mounting seat 3, the power transmission path is short and the loss is small, ensuring the cable reel rotation efficiency and further improving the winding and unwinding operation efficiency, solving the low efficiency of manual winding and unwinding in the background technology.

[0030] Further, the driving motor 2 can provide continuous and stable automatic power output, replacing the traditional manual dragging operation, not only greatly reducing the labor intensity of the construction personnel, but also ensuring the uniformity of the cable winding and unwinding speed through precise speed control, effectively avoiding the uneven cable tension caused by the force being too large or too small during manual operation. In addition, the driving motor 2 is directly fixedly connected with the first mounting seat 3, the power transmission path is short and the loss is small, ensuring the cable reel rotation efficiency and further improving the winding and unwinding operation efficiency, solving the low efficiency of manual winding and unwinding in the background technology.

[0031] Here, the first mounting seat 3 and the second mounting seat 4 are coaxially arranged, which can provide stable support from both ends of the cable reel and avoid eccentric shaking during reel rotation. At the same time, the second mounting seat 4 can be adjusted in position along the track 6, breaking the limitation of traditional winding and unwinding devices that can only adapt to single-width reels. The distance between the two mounting seats can be flexibly adjusted according to different specifications of the cable reel, greatly improving the universality of the device. The first mounting seat 3 is fixedly connected with the driving motor 2, which can also ensure stable power transmission to the reel and ensure the continuity of the winding and unwinding action.

[0032] Further, the track 6 provides a directional sliding path for the second mounting seat 4, strictly limiting its movement direction to only along the length direction of the bottom plate 1, ensuring that the second mounting seat 4 always maintains coaxiality with the first mounting seat 3 during adjustment, avoiding eccentric vibration of the cable reel during rotation due to mounting seat offset, thereby reducing the friction and wear between the cable and the edge of the mounting seat, and reducing the abnormal noise during device operation, prolonging the service life of the equipment.

[0033] Further, the limit holes 7 are linearly arrayed along the length direction of the bottom plate 1, providing multiple gear positioning points for the second mounting seat 4, which can realize precise fixing of different width cable reels in cooperation with the limiting part. For example, when a small-width reel is installed, the second mounting seat 4 can be locked by sliding to the position of the limit hole 7 close to the first mounting seat 3; when a wide reel is installed, it is locked by sliding to the far end, ensuring that the second mounting seat 4 can be stably fixed regardless of the width of the reel, avoiding axial movement of the mounting seat during winding and unwinding.

[0034] The second mounting seat 4 is provided with a lifting device for positioning, which comprises a support 8 fixedly connected to the second mounting seat 4, a threaded rod 9 threadedly connected to the support 8, and a limiting rod 10 rotationally connected to the end of the threaded rod 9 without threads, wherein a guide rod 11 is symmetrically installed on the limiting rod 10 and slidably connected to a guide ring on the second mounting seat 4, and when the limiting rod 10 is coaxially inserted into a limiting hole 7 at a corresponding position, the limiting rod 10 is locked in the limiting hole 7.

[0035] Here, the limiting part is realized by multiple components in cooperation to quickly and stably lock the second mounting seat 4, which is convenient to operate and has high locking reliability. The support 8 provides vertical support for the threaded rod 9 to ensure smooth force transmission during adjustment and prevent the threaded rod 9 from being skewed. The threaded rod 9 drives the limiting rod 10 to rise and fall through threaded transmission, and the operator only needs to rotate the threaded rod 9 to complete locking and unlocking without the need for complex tools, which is efficient. The limiting rod 10 is mechanically rigidly locked after being inserted into the limiting hole 7, which has higher connection strength than the buckle type structure and can resist the impact force when the reel rotates to prevent the mounting seat from loosening. The guide rod 11 slides along the guide ring of the second mounting seat 4 to strictly limit the movement direction of the limiting rod 10 to vertical lifting to prevent it from being skewed and unable to be accurately inserted into the limiting hole 7, further ensuring the locking effect.

[0036] A rotating rod 5 is rotationally arranged on the bottom plate 1 to stably fix the cable reel, and when the rotating rod 5 contacts the side wall of the cable reel, a stable area is formed. The rotating rod 5 is provided with an adjusting part for adapting to the size of the cable reel, which comprises a connecting frame 12 symmetrically installed on the bottom plate 1, and two groups of rotating rods 5 rotationally connected to the corresponding connecting frames 12. The rotating rod 5 is symmetrically provided with an adjusting ring 13 for adapting to the cable reel, and when the adjusting ring 13 moves to the position of the corresponding cable reel, the adjusting ring 13 is locked on the rotating rod 5 by a bolt. The adjusting ring 13 is arranged in a stepped manner.

[0037] Here, the rotating rod 5 can be flexibly rotated around the connecting frame 12, and the angle can be adjusted according to the diameter of the cable reel to tightly fit the side wall of the reel to form a stable area, effectively preventing the reel from shaking radially during winding and unwinding.

[0038] Further, the adjusting part can accurately adapt to cable reels of different sizes, improving the universality and fit of the stable structure. The connecting frame 12 is symmetrically installed on the bottom plate 1 to provide a symmetric installation base for the two groups of rotating rods 5, ensuring that the stable force exerted by the rotating rods 5 is evenly distributed on both sides of the reel, avoiding the offset of the reel caused by unilateral force. The adjusting ring 13 can slide along the rotating rod 5, and after adjusting the position according to the width of the reel, it can be locked by bolts. It can adapt to reels of different widths. The adjusting ring 13 is arranged in a stepped manner, and different stepped surfaces can fit the side walls of reels of different diameters, reducing the contact area with the reel to reduce friction resistance, while ensuring close fit, solving the problem that traditional stable structures cannot adapt to reels of multiple sizes.

[0039] One group of rotating rods 5 is located at the bottom of the bottom plate 1, and the other group of rotating rods 5 is located in the middle of the cable reel, forming a diagonal stable area between the two groups of rotating rods 5.

[0040] Here, the advantage of the diagonal distribution of the two groups of rotating rods 5 is to form a diagonal stable area, exerting a limiting force on the cable reel from different heights, thereby improving the anti-shaking effect. The rotating rod 5 at the bottom can limit the radial displacement of the lower part of the reel, and the rotating rod 5 in the middle can limit the displacement of the middle part of the reel. The two can jointly offset the radial impact force generated when the reel rotates, effectively preventing the reel from moving axially or toppling over, especially for heavy cable reels, further improving the safety of the device in operation.

[0041] Further, the rotating rod 5 located in the middle can also cooperate with the tensioning part to provide certain tension support for the cable. During the cable winding and unwinding process, the middle rotating rod 5 can indirectly contact the cable layer on the side of the cable reel through the adjusting ring 13, assisting in sharing the tension adjustment pressure of the tensioning part, avoiding the local wear of the cable caused by the excessive force of the single structure of the tensioning roller 15, and at the same time enhancing the tension stability of the cable during winding and unwinding. Especially when the diameter of the reel changes during winding and unwinding, it can cooperate with the tensioning part to smoothly transition the tension, further reducing the risk of knotting or breaking of the cable due to tension fluctuation. This dual function makes the function of the rotating rod 5 more comprehensive, improving the overall synergy of the device.

[0042] The tensioning part is rotatably arranged on the bottom plate 1 for adjusting the tension of the cable. The tensioning part includes a U-shaped frame 14 rotatably arranged on the top of the connecting frame 12. The U-shaped frame 14 is rotatably connected with a tensioning roller 15 for adjusting the tension of the cable. The connecting frame 12 is arc-shaped and equidistantly provided with locking holes 16 along the overturning path of the U-shaped frame 14. When the U-shaped frame 14 is overturned, the U-shaped frame 14 and the corresponding locking hole 16 are locked by bolts.

[0043] Here, the tension part realizes flexible adjustment and stable maintenance of the cable tension, while reducing the cable wear. The U-shaped frame 14 can be flipped around the rotating shaft of the connecting frame 12 to drive the tension roller 15 to adjust the contact angle with the cable, thereby changing the tension of the cable. When it is needed to increase the tension, the U-shaped frame 14 can be flipped downward to press the tension roller 15 against the cable; when it is needed to reduce the tension, the U-shaped frame 14 can be flipped upward, which is flexible in operation. The tension roller 15 is in rolling contact with the cable, which can reduce the wear rate of the cable surface compared with the traditional fixed friction structure, thereby effectively protecting the cable insulation layer and the internal core wire. The arc-shaped limiting holes 7 are equidistantly distributed along the flipping path of the U-shaped frame 14, and the U-shaped frame 14 is fixed in the corresponding limiting hole 7 through a bolt, so as to lock the angle of the tension roller 15 and ensure that the tension is stable during the winding and unwinding process, thereby avoiding the cable knotting or core wire breaking caused by sudden change of the tension.
