Description

Technical Field

[0001] The embodiments disclosed herein relate to the technical field of cable reel winding and unwinding devices, specifically, to a cable reel winding and unwinding device. Background Technology

[0002] In cable laying and recycling operations in industries such as power and telecommunications, cable reel winding and unwinding devices are key equipment for achieving efficient cable transfer and storage. However, current cable reel winding and unwinding devices have significant drawbacks in the loading, unloading, and transfer of coiled cables, which restricts construction efficiency and operational safety.

[0003] Traditional cable reel winding and unwinding devices can handle coils weighing hundreds or even thousands of kilograms after winding up the cable. Due to the lack of suitable loading and unloading mechanisms, operators need to use large equipment such as cranes and forklifts for the operation. This not only increases equipment scheduling costs but also makes it difficult to operate in narrow construction sites, resulting in low loading and unloading efficiency and excessively long time for each transfer.

[0004] Furthermore, coiled cables are prone to tilting and rolling during loading and unloading due to the lack of stable support. This can not only cause wear on the cable sheath and breakage of the internal core, but also pose a safety hazard of injuring operators. With the intensive development of urban power grid renovation and communication line laying projects, construction sites are becoming increasingly complex. The inconvenience of loading, unloading, and transferring traditional equipment due to the heavy weight of coiled cables has become a prominent bottleneck restricting construction progress and operational safety.

[0023] like Figures 1-4 As shown, a cable reel winding and unwinding device according to an embodiment of the present disclosure is illustrated, comprising: A base plate 1 and an upright plate 2, wherein the upright plate 2 is fixed on the base plate 1; The roller 3 and the support winding assembly 5 are provided. The roller 3 is disposed on the vertical plate 2, and the support winding assembly 5 is disposed between the roller 3 and the vertical plate 2. A pair of side rods 4 and a guide assembly 6, wherein the side rods 4 are fixed at both ends of the surface of the upright plate 2, and the guide assembly 6 is disposed between the side rods 4; The support and retraction assembly 5 includes a vertical cavity 5-1, which is formed within the vertical plate 2. A fork 5-2 connected via a vertical linear drive is disposed within the vertical cavity 5-1. A base 5-3 is fitted to the front end of the fork 5-2. A pair of sliding grooves 5-4 are formed on the surface of the base 5-3. The protruding portions at both ends of the drum 3 are slidably embedded in the sliding grooves 5-4. A pair of horizontal cavities 5-5 are formed on the surface of the vertical plate 2. Several horizontal bars 5-6 are disposed within each horizontal cavity 5-5. Side plates 5-7 are slidably fitted onto the horizontal bars 5-6. The side bars 5-7 are connected via a horizontal linear drive. A drive seat 5-8 is rotatably connected to the side surface of each side plate 5-7. One of the drive seats 5-8 is electrically driven to rotate. The drive seat 5-8 is inserted into both ends of the drum 3. The surface of the drive seat 5-8 is an inclined conical structure. Moving wheels 5-9 are provided at the four opposite corners of the bottom of the base 5-3.

[0024] In some examples, a support and retraction assembly 5 is designed to enable the winding and unwinding operation and ground movement of the drum 3. This assembly includes a vertical cavity 5-1 opened vertically within the upright plate 2, a vertical linear drive device (such as a lead screw 6-4) fixed at the bottom of the vertical cavity 5-1, and its output end connected to the rear end of the fork 5-2. The front end of the fork 5-2 is horizontally inserted into the base 5-3, and the sliding groove 5-4 on the surface of the base 5-3 extends along the length direction to match the protrusions at both ends of the drum 3. A horizontal cavity 5-5 is opened horizontally on the surface of the upright plate 2, and a crossbar 5-6 is fixed along the length direction of the horizontal cavity 5-5. A side plate 5-7 is slidably fitted onto the crossbar 5-6 via a sliding sleeve. The output end of the horizontal linear drive device (such as a cylinder) is connected to the side plate 5-7, which can push the side plate 5-7 to move along the crossbar 5-6. The drive seat 5-8 on the side surface of the side plate 5-7 is rotatably connected by a bearing. One of the drive seats 5-8 is connected to the motor output end through a coupling. The tapered structure on the surface matches the tapered holes at both ends of the drum 3. The moving wheel 5-9 at the bottom of the base 5-3 can roll on the ground. During operation, the vertical linear drive unit pushes the fork 5-2 upward, lifting the base 5-3 and causing the drum 3 to leave the ground. The horizontal linear drive unit pushes the side plate 5-7 to move along the crossbar 5-6. The conical structure of the drive seat 5-8 is inserted into both ends of the drum 3, and the motor drives the drive seat 5-8 to rotate, realizing cable winding and unwinding. When it is necessary to move the drum 3, the vertical linear drive unit drives the fork 5-2 downward, the base 5-3 contacts the ground, the moving wheels 5-9 support the drum 3, and pushing the base 5-3 allows it to move on the ground. The fitted connection between the fork 5-2 and the base 5-3 adapts to changes in the lifting angle of the drum 3. The slide groove 5-4 facilitates loading and unloading of the drum 3 on the base 5-3. The conical drive seat 5-8 ensures stable power transmission, and the crossbar 5-6 ensures smooth movement of the side plate 5-7. This component, through the combination of lifting and driving, not only realizes the winding and unwinding of the drum 3 but also allows for convenient movement, improving operational flexibility.

[0025] like Figures 1-4 As shown in the figure, the guide assembly 6 in this embodiment includes a crossbeam 6-1, which is fixed between the side rods 4. A slide rail 6-2 is provided on the surface of the crossbeam 6-1, and a movable frame 6-3 is slidably connected to the slide rail 6-2. A lead screw 6-4 driven by electricity is provided between the side rods 4. The lead screw 6-4 is connected to the movable frame 6-3 by a threaded connection. A pair of pulleys 6-5 are rotatably connected inside the movable frame 6-3. The pulleys 6-5 are vertically distributed. A guide hole 6-6 is provided on the inner surface of the movable frame 6-3.

[0026] In some examples, a guide assembly 6 is designed to achieve stable cable delivery. This assembly includes a crossbeam 6-1 between the side rods 4, which is fixed by bolts. A slide rail 6-2 is laid along the length of the surface. A slider at the bottom of the movable frame 6-3 is slidably connected to the slide rail 6-2. A lead screw 6-4 between the side rods 4 is rotatably connected by bearings and driven by a motor. It engages with a threaded hole in the middle of the movable frame 6-3, allowing the movable frame 6-3 to slide along the slide rail 6-2. The cable wheels 6-5 inside the movable frame 6-3 are rotatably connected by bearings and are vertically distributed to form a clamping space. The surface of the wheel has an arc-shaped groove to fit the cable. The guide hole 6-6 on the inner surface of the movable frame 6-3 is a circular through hole, corresponding to the position of the cable wheel 6-5.

[0027] During operation, the motor drives the lead screw 6-4 to rotate, and the moving frame 6-3 moves horizontally along the crossbeam 6-1 under the guidance of the slide rail 6-2. After the cable passes through the guide hole 6-6, it passes between the upper and lower cable pulleys 6-5, which rotate as the cable moves. The arc-shaped groove of the cable pulley 6-5 provides lateral restraint for the cable, and the upper and lower distributed structure can adjust the clamping force to prevent cable deviation or wear. The guide hole 6-6 guides the cable into the area of ​​the cable pulley 6-5, and the horizontal movement of the moving frame 6-3 can adapt to the winding position of the cable on the drum 3. The lead screw 6-4 transmission enables precise control of the position of the moving frame 6-3, and the slide rail 6-2 ensures smooth movement. This component, through the combination of guidance and clamping, ensures smooth cable delivery during winding and unwinding, avoids tangling and knotting, and improves winding and unwinding efficiency.

[0028] For example, such as Figure 1 As shown, the surfaces of the spools 6-5 are all concave, and the openings at both ends of the guide holes 6-6 are flared.

[0029] In some examples, the concave structure on the surface of the reel 6-5 conforms to the outer surface of the cable, enhancing the wrapping effect and preventing deviation during transport. The flared openings at both ends of the guide perforation 6-6 guide the cable smoothly into the perforation, reducing frictional damage to the cable sheath at the entrance. The combination of the concave structure and the flared opening ensures the cable remains stable and does not wobble during transport, while also reducing the risk of sheath wear, thus improving the safety and stability of the transport process.

[0030] For example, such as Figure 4 As shown, the portions of the base 5-3 located at both ends of the slide groove 5-4 are arc-shaped transition structures, and the curvature of the slide groove 5-4 matches the curvature of the surface of the drum 3.

[0031] In some examples, the arc-shaped transition structure of the sliding grooves 5-4 at both ends of the base 5-3 can precisely fit the curvature of the surface of the drum 3, preventing the drum 3 from getting stuck when placed on the base 5-3. The arc-shaped transition allows the protrusions at both ends of the drum 3 to slide more smoothly along the sliding grooves 5-4, facilitating the loading and unloading of the drum 3, while also enhancing the stability of the drum 3 when placed, preventing the drum 3 from shaking during winding and unwinding, and ensuring the smooth progress of winding and unwinding operations.

[0032] For example, such as Figure 1 As shown, the front end of the base plate 1 has a sloping structure.

[0033] In some examples, the sloping structure at the front end of the base plate 1 facilitates the movement of the drum 3 onto the base plate 1. The sloping design reduces the height difference between the drum 3 and the plate, allowing operators to easily push the drum 3 along the slope to the designated position, reducing handling effort and improving the ease of loading and unloading the drum 3. This is especially suitable for moving heavy drums 3, enhancing the practicality of the device.

[0034] In actual use: The drum 3 is pushed along the slope of the base plate 1 to the base 5-3, so that its two protrusions are embedded in the slide grooves 5-4. The vertical linear drive pushes the fork 5-2 to rise, causing the base 5-3 and the drum 3 to lift. The horizontal linear drive pushes the side plate 5-7 to move along the crossbar 5-6, and the conical drive seat 5-8 is inserted into both ends of the drum 3 for fixation. The motor drives the drum 3 to rotate and wind up and unwind the cable. The cable passes through the guide hole 6-6, is guided by the upper and lower pulleys 6-5, and the lead screw 6-4 drives the moving frame 6-3 to slide along the slide rail 6-2, adjusting the winding and unwinding position in conjunction with the drum 3. After completion, the fork 5-2 lowers so that the base 5-3 touches the ground, the moving wheel 5-9 supports the drum 3, and the drive seat 5-8 is released for pushing and transporting. No large equipment is required throughout the process, ensuring stable operation.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
