Description

Technical Field

[0001] This utility model relates to the field of cable equipment technology, and more specifically, to an auxiliary device applicable to the winding and unwinding of cable reels of various specifications. Background Technology

[0002] Cable reels are reels used by industrial and mining enterprises to wind electrical wires and cables. They are widely used in industries such as electronics, power, railways, petrochemicals, mining, and construction, and are essential for infrastructure construction. Currently, Chinese patent CN222540163U discloses a communication cable winding and unwinding rack, including a base and a support seat. A connecting shaft is located at the top center of the support seat. By inserting the connecting shaft into the inside of the cable reel and rolling the cable reel inwards towards the support plate, the top of the connecting shaft rolls to the top of the support seat. This causes the support seat to move upwards, supporting the cable reel upwards via the connecting shaft, separating the bottom of the cable reel from the ground. Simultaneously, a motor drives a gear to rotate, causing the connecting shaft to rotate on a roller, thus enabling the connecting shaft to drive the cable reel in cable winding and unwinding operations. For example, Chinese patent CN218320051U discloses a mobile cable reel rack, including a mobile platform and casters. A support rod is fixedly installed on one side of the top of the mobile platform, and a second motor is fixedly installed in the middle of one side of the support rod. One end of the second motor passes through one side of the support rod and is connected to a drive shaft. A cable rack is sleeved around the drive shaft, allowing for the reeling and unloading of cables. In practical use, since cable reels have different sizes depending on the cable specifications and length, installing cable reels using the two methods described above requires designing different sizes of connecting shafts / drive shafts to match the cable reel drums. When using different sizes of cable reels, the connecting shaft / drive shaft needs to be replaced, which not only makes operation cumbersome and reduces work efficiency but also increases equipment costs.

Detailed Implementation

[0020] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Example 1

[0022] Please see Figure 1 As shown, an auxiliary device for winding and unwinding cable reels of various specifications provided by an embodiment of this utility model will now be described. The cable reel has an upper plate 10, a lower plate 11, and a drum 12 connected between the upper plate 10 and the lower plate 11. The drum 12 has a central through hole. The auxiliary device includes a rotating tray 13, a central shaft 14, and an inner support assembly. One end of the central shaft 14 is connected to the rotating tray 13, and the other end extends upwards from the rotating tray 13. The rotating tray 13 can rotate and drive the central shaft 14 to rotate. The central shaft 14 passes through the central through hole of the drum 12. The inner support assembly includes a tensioning block 15 and a driving structure. The driving structure is connected to the central shaft 14 and drives the tensioning block 15 to move radially along the central shaft 14. When the tensioning block 15 abuts against the inner wall of the central through hole of the drum 12, the cable reel is fixedly connected to the central shaft 14. Specifically, the rotating tray 13 is used to support the cable reel, the central shaft 14 is vertically positioned above the rotating tray 13, and the cable reel is vertically positioned above the rotating tray 13. The central shaft 14 passes through the central through hole, meaning the upper plate 10 of the cable reel is positioned above the lower plate 11. Because the cable reel rests on the rotating tray 13 by its own weight and can rotate with the rotating tray 13, it is more stable when rotating compared to a traditional horizontally positioned cable reel. The cable reel's drum 12 is used to wind the cable. The drive structure of the inner support assembly is located on the central shaft 14, and drives the tensioning block 15 through the drive structure. The support block 15 moves radially along the central axis 14 to approach or move away from the central axis 14, thereby adjusting the relative position of the support block 15 and the inner wall of the central through hole of the drum 12. When the auxiliary device is in working condition, the support block 15 abuts against the inner wall of the central through hole of the drum 12, and the cable reel is fixedly connected to the central axis 14, so that the cable reel can rotate stably with the rotating tray 13. When it is necessary to replace the cable reel of other specifications, the support block 15 can be moved towards the central axis 14, the support block 15 is separated from the inner wall of the central through hole of the drum 12, and the cable reel and the central axis 14 can be disassembled for replacement.

[0023] The drive structure includes a fixing member 16, a sliding member 17, a connecting rod assembly, and a locking member 18. The fixing member 16 is fixedly connected to the central shaft 14 and located above the rotating tray 13. The sliding member 17 is slidably connected to the central shaft 14 and can move axially along the central shaft 14. The connecting rod assembly includes a first connecting rod 19 and a second connecting rod 20. The first connecting rod 19 and the second connecting rod 20 are located at the upper and lower ends of the support block 15, respectively. The two ends of the first connecting rod 19 are rotatably connected to the support block 15 and the fixing member 16, respectively. The two ends of the second connecting rod 20 are rotatably connected to the support block 15 and the sliding member 17, respectively. The locking member 18 is used to limit the axial position of the sliding member 17 on the central shaft 14. Specifically, in this embodiment, the fixing member 16 is sleeved on the central shaft 14 and fixedly connected to the central shaft 14, and the sliding member 17 is sleeved on the central shaft 14 and can move up and down along the central shaft 14. By moving the sliding member 17, the first connecting rod 19 and the second connecting rod 20 are driven to rotate, so that the first connecting rod 19 and the second connecting rod 20 work together to make the support block 15 move closer to or away from the central shaft 14 radially. The locking member 18 can fix the sliding member 17 on the central shaft 14 or release it from the central shaft 14. When there is a gap between the central shaft 14 and the inner wall of the central through hole of the drum 12, the sliding member 17 is moved, causing the support block 15 to move away from the central shaft 14. When the support block 15 abuts against the inner wall of the central through hole of the drum 12, the position of the sliding member 17 is fixed by the locking member 18, thus achieving a fixed connection between the central shaft 14 and the cable reel. When it is necessary to replace the cable reel on the rotating tray 13, the sliding member 17 is released by the locking member 18, and then the sliding member 17 is moved, causing the support block 15 to move closer to the central shaft 14. When the sliding member 17 slides into place, the locking member 18 is used to fix the sliding member 17. At this time, the support block 15 separates from the inner wall of the central through hole of the drum 12, allowing the cable reel to be replaced. The distance between the support block 15 and the inner wall of the central through hole of the drum 12 can be adjusted by controlling the sliding member 17 to move up and down along the central shaft 14. This structure is simple and facilitates quick operation.

[0024] The slider 17 is located above the fixed member 16. By moving the slider 17 upward, the support block 15 moves closer to the central axis 14; by moving the slider 17 downward, the support block 15 moves away from the central axis 14. Since the slider 17 is located above the fixed member 16, it is convenient to fix or release the slider 17.

[0025] The linkage assembly also includes a third link 21, which is located between the first link 19 and the second link 20. Both ends of the third link 21 are rotatably connected to the support block 15 and the central shaft 14, respectively. Specifically, in this embodiment, a connecting lug is provided on the outer wall of the central shaft 14. This connecting lug is located between the sliding member 17 and the fixing member 16. The connecting lug is pivotally connected to one end of the third link 21, and the other end of the third link 21 is pivotally connected to the support block 15. The other end of the third link 21 is located between the upper and lower ends of the support block 15. By providing the third link 21, the support block 15 is further supported, ensuring greater stability when the support block 15 abuts against the inner wall of the central through hole of the drum 12.

[0026] The locking member 18 is threadedly connected to the sliding member 17, and the locking member 18 can move radially along the central axis 14. When the locking member 18 abuts against the central axis 14, the sliding member 17 is fixed on the central axis. Specifically, in this embodiment, the locking member 18 is a tightening bolt, and the sliding member 17 is provided with a threaded through hole in the circumference. The screw of the tightening bolt is inserted into the threaded through hole. By tightening the tightening bolt, the screw is brought closer to the central axis 14. When the screw abuts against the outer wall of the central axis 14, the sliding member 17 is fixed on the central axis 14, thereby preventing the sliding member 17 from sliding relative to the central axis 14. By tightening the tightening bolt, the screw is moved away from the central axis 14. When the screw is separated from the central axis 14, the sliding member 17 is released and can slide relative to the central axis 14. Example 2

[0027] For easier control of the internal support components, see [link / reference] Figure 2 As shown, the drive structure includes a hydraulic cylinder 22 and a connecting rod assembly. The body of the hydraulic cylinder 22 is mounted on the central shaft 14, and the drive end of the hydraulic cylinder 22 is located above the body of the hydraulic cylinder 22. The connecting rod assembly includes a first connecting rod 19 and a second connecting rod 20, which are located at the upper and lower ends of the support block 15, respectively. The two ends of the first connecting rod 19 are rotatably connected to the support block 15 and the body of the hydraulic cylinder 22, respectively, and the two ends of the second connecting rod 20 are rotatably connected to the support block 15 and the drive end of the hydraulic cylinder 22, respectively. Specifically, in this embodiment, the body of the hydraulic cylinder 22 is fixedly mounted on the top of the central shaft 14, wherein the top of the central shaft 14 is located below the upper plate 10. By controlling the extension and retraction of the drive end of the hydraulic cylinder 22, the first connecting rod 19 and the second connecting rod 20 are rotated to make the support block 15 move closer to or away from the central shaft 14 radially. The radial displacement of the support block 15 is adjusted by the hydraulic cylinder 22, making the overall structure of the device simpler, with higher control precision and faster operation. Example 3

[0028] See Figure 1 and Figure 2As shown, in this embodiment, there are multiple tension blocks 15 and multiple connecting rod assemblies, each corresponding to the other, and they are evenly distributed around the central axis 14. By providing multiple tension blocks 15, the drum 12 can be tightened and fixed, and the drum 12 can be subjected to a more uniform tension force, making the central axis 14 more stably fixed to the cable reel. Example 4

[0029] See Figure 1 and Figure 2 As shown, in this embodiment, multiple rollers 23 are installed below the rotating tray 13. These rollers 23 are symmetrically distributed about the central axis 14 of the rotating tray, and can rotate with the rotating tray 13. Understandably, the rotating tray 13 can rotate more easily with the assistance of the rollers 23. By providing multiple rollers 23 and symmetrically distributing them about the central axis 14, the rotating tray 13 can be stably supported, ensuring stable rotation along a set direction. Specifically, in this embodiment, there are eight rollers 23, which are symmetrical about the central axis 14 and located on the same circumference. Example 5

[0030] See Figure 1 and Figure 2 As shown, the auxiliary device applicable to cable reel winding of various specifications also includes a base plate 24 located below the rotating tray 13, rollers 23 abutting against the top of the base plate 24, and a central shaft 14 extending downwards and rotatably connected to the base plate 24 at one end connected to the rotating tray 13. Understandably, with the assistance of the base plate 24, the rollers 23 can move smoothly, preventing uneven ground from affecting their rotation; the rotatable connection between the central shaft 14 and the base plate 24 prevents the rotating tray 13 from shifting or deflecting during rotation. Preferably, the end of the central shaft 14 located below the rotating tray 13 can be rotatably connected to the base plate 24 via a bearing 25.

[0031] Preferably, a track is provided above the base plate 24, and the roller 23 is disposed in the track to ensure that the roller 23 moves along the track direction, thereby avoiding deflection. Example 6

[0032] See Figure 1 and Figure 2As shown, in this embodiment, the auxiliary device also includes a motor 26 and a transmission assembly. The motor 26 drives the rotating tray 13 to rotate through the transmission assembly. The transmission assembly includes at least one of a belt drive assembly, a chain and sprocket drive assembly, and a gear drive assembly. Since existing cable winding and unwinding devices typically require manual operation, resulting in low efficiency and inconvenience, the above-described configuration utilizes the motor 26 and transmission assembly to rotate the rotating tray 13. This allows the motor 26 to control cable winding and unwinding, enabling quick operation, improving work efficiency, and saving manpower.

[0033] Taking a belt drive assembly as an example, the belt drive assembly includes a drive wheel 27 and a synchronous belt 28. The rotating tray 13 is the driven pulley, the drive wheel 27 is the driving pulley, the motor 26 is mounted on the base plate 24, and the output end of the motor 26 is connected to the drive wheel 27. The drive wheel 27 is connected to the rotating tray 13 through the synchronous belt 28. The motor 26 drives the drive wheel 27 to rotate, and the drive wheel 27 drives the rotating tray 13 to rotate through the synchronous belt 28.

[0034] The transmission assembly can also be a gear transmission assembly. For example, the drive wheel 27 and the rotating tray 13 are gear disks, and the motor 26 drives the drive wheel 27 to rotate. The drive wheel 27 meshes with the rotating tray 13, thereby causing the rotating tray 13 to rotate.

[0035] In summary, the auxiliary device for cable reel winding and unwinding of various specifications provided in this embodiment has at least the following beneficial technical effects:

[0036] (1) The support block 15 is driven to move radially along the central axis 14 by the drive structure in the inner support assembly, thereby adjusting the relative position of the support block 15 and the inner wall of the central through hole of the drum 12 so that the central axis 14 is fixedly connected to cable reels of different sizes and specifications. Thus, the auxiliary device is applicable to cable reels of various specifications, thereby reducing equipment costs and making operation simple and conducive to improving work efficiency.

[0037] (2) The rotating tray 13 is rotated by the motor 26 and the transmission assembly. The cable can be retracted and extended by the motor 26, which can realize quick operation, improve work efficiency and save manpower.

[0038] (3) By setting multiple rollers 23 under the rotating tray 13, the rotating tray 13 can not only be stably supported, but also the rotating tray 13 can be stably rotated in the set direction.

[0039] (4) By setting multiple tensioning blocks 15, the multiple tensioning blocks 15 can tighten and fix the drum 12, and the drum 12 can be subjected to a more uniform tensioning force, making the central shaft 14 and the cable reel more stable.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
