Description

Technical Field

[0001] This utility model relates to the field of cable reel equipment, and in particular to a cable reel support device. Background Technology

[0002] In cable manufacturing, power construction, and telecommunications engineering, cable reels are crucial equipment for winding and storing cables. Currently, most reel support devices use a central shaft drive for rotational winding, where a motor drives a rigid main shaft running through the center of the reel. While this structure is common in industrial applications, it has several technical drawbacks: Central shaft drive requires a precise match between the reel's center hole and the drive shaft. However, reels from different manufacturers have varying inner diameters, making it difficult for the same equipment to accommodate multiple sizes. Even slight deformation or wear in the reel's center hole can cause installation difficulties, affecting transmission accuracy and increasing maintenance costs. Central shaft drive requires precise alignment and insertion of the reel into the drive shaft; for large or heavy reels, lifting equipment is often needed for positioning, making the process cumbersome and time-consuming. In scenarios involving frequent reel replacements, repeated disassembly and reassembly of the central shaft reduces efficiency and impacts production cycle time. The central shaft must bear the entire weight and rotational torque of the reel; prolonged use can lead to shaft bending or bearing wear, affecting transmission stability. If the load on the take-up reel is uneven, the central shaft and support structure are susceptible to additional radial forces, accelerating fatigue damage to mechanical components. Traditional central shaft drives are rigid connections and cannot adapt to minute offsets in the take-up reel during rotation, potentially leading to increased vibration or noise. For reels of different widths, the shaft end limit device needs manual adjustment, which is inconvenient. Therefore, improvements are needed to the existing take-up reel structure.

[0004] According to an embodiment of this utility model, a cable reel support device includes a base plate, two lifting frames, two limiting components, a motor, a sliding frame, and rubber rollers. The two lifting frames are fixed to the top surface of the base plate and spaced apart. The two limiting components are respectively disposed on the top of the lifting frames, and the limiting components can extend laterally into the interior of the reel.

[0005] The technical principle of this utility model is as follows: axial positioning is achieved by inserting the limiting components on both sides of the lifting frame into the center of the take-up reel. At the same time, the rubber roller driven by the motor presses the outer edge of the take-up reel, and the take-up reel is rotated by friction transmission. The sliding frame can adjust the pressing force between the rubber roller and the take-up reel to ensure effective driving.

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1 As shown in the figure, this utility model embodiment proposes a cable reel support device, including a base plate 1, two lifting frames, two limiting components, a motor 11, a sliding frame 10, and a rubber roller 9. The two lifting frames are fixed to the top surface of the base plate 1 and spaced apart. The two limiting components are respectively disposed on the top of the lifting frames, and the limiting components can extend laterally into the interior of the reel. The sliding frame 10 is disposed below one of the limiting components. The motor 11 is slidably connected to the sliding frame 10, and the sliding direction of the motor 11 is perpendicular to the rotation surface of the reel. The rubber roller 9 is fixedly disposed on the output shaft of the motor 11, and the rubber roller 9 is coaxial with the output shaft of the motor 11 and vertically disposed. The operator moves the take-up reel between the two lifting frames, then inserts the limiting component into the center of the take-up reel. The lifting component extends upward to raise the height of the limiting component, causing the bottom of the take-up reel to detach from the base plate 1 and suspend in the air. The sliding motor 11 causes the rubber roller 9 to press against the outer edge of the take-up reel. The motor 11 drives the rubber roller 9 to rotate the take-up reel through friction transmission. After the take-up is completed, the lifting component retracts, the base plate 1 supports the take-up reel, and then the limiting component withdraws from the take-up reel, allowing the take-up reel to be transferred.

[0019] Preferably, the lifting frame includes a U-shaped support portion 2 and a first telescopic rod 3 fixedly mounted on the top of the support portion 2. The fixed end of the first telescopic rod 3 is fixedly connected to the support portion 2, and the movable end of the first telescopic rod 3 extends upward. The lifting frame structure using the U-shaped support portion 2 and the first telescopic rod 3 allows for flexible height adjustment to accommodate different sizes of take-up reels while maintaining structural stability. The U-shaped structure facilitates the installation of the sliding frame 10.

[0020] Preferably, the limiting assembly includes a connecting sleeve 4, a sliding rod 5, and a limiting plate 7. The connecting sleeve 4 is fixedly connected to the movable end of the first telescopic rod 3, and the connecting sleeves 4 on both sides are coaxially arranged. The sliding rod 5 is slidably disposed inside the connecting sleeve 4. By adjusting the extension and retraction of the sliding rod 5 within the connecting sleeve 4, it can flexibly adapt to take-up reels of different widths, while ensuring limiting stability and ease of installation. The end of the sliding rod 5 is smaller than the diameter of the inner hole of the central shaft of the take-up reel, ensuring that the end of the sliding rod 5 can be inserted into the take-up reel.

[0021] Preferably, the connecting sleeve 4 is rotatably mounted with a limiting plate 7 at the end of the lifting frame on the other side. The rotatably mounted limiting plate 7 can quickly clamp the outer wall of the take-up reel, achieving stable positioning and adapting to take-up reels with different inner diameters.

[0022] Preferably, the assembly also includes a screw 15, a spring 14, a fixing block 12, a sliding block 13, and a crank handle 16.

The middle part of the screw 15 is threadedly connected to the support part 2. The crank handle 16 is disposed at the free end of the screw 15. Rotating the crank handle 16 pushes the screw 15 to push the sliding block 13 and compress the spring 14, causing the motor 11 to drive the rubber roller 9 to elastically press against the edge of the take-up reel, achieving adjustable pressure friction transmission.

[0023] Preferably, the sliding frame 10 has a rectangular frame structure, and the motor 11 is slidably disposed inside the sliding frame 10. In this embodiment, the motor 11 body is a cuboid, and the four parallel sides of the sliding frame 10 and the motor 11 are slidably connected. The output shaft of the motor 11 extends to the outside of the sliding frame 10 for easy connection with the rubber roller 9.

[0024] Preferably, the sliding rod 5 includes a conical section and a rectangular section, with the conical section and the rectangular section coaxially and rotatably connected at their adjacent ends. The rectangular section is axially slidably connected to the connecting sleeve 4. The connecting sleeve 4 is provided with a positioning pin 6, and the rectangular section is provided with a matching pin hole. The sliding rod 5 adopts a combination structure of conical and rectangular sections, achieving rapid positioning through the cooperation of the positioning pin 6 and the pin hole. The conical section can adapt to the inner hole of the take-up reel, while the rectangular section ensures stable axial sliding.

[0025] Preferably, a second telescopic rod 8 is vertically arranged at the bottom of the sliding frame 10. The fixed end of the second telescopic rod 8 is fixedly connected to the base plate 1, and the movable end of the second telescopic rod 8 is fixedly connected to the bottom of the sliding frame 10.
