Description

Technical Field

[0001] This utility model relates to the field of cable winding and unwinding devices, and more specifically, to a motor-driven cable winding and unwinding device. Background Technology

[0002] A cable is an electrical or signal transmission device, typically consisting of several or groups of conductors (each group containing at least two conductors) twisted together in a rope-like manner. Each group of conductors is insulated from each other and is often twisted around a central core, with the entire cable covered by a highly insulating outer layer.

[0003] During cable laying, power workers need to lay the cable reel flat and then drag it around in circles. This is not only labor-intensive but also very slow, severely impacting the laying progress. Existing cable reel-and-winding devices require forklifts for cable placement. However, due to support columns between the rotating rods, the space is limited by these columns during forklift operation, making it difficult to position the cable reel precisely on the rotating rod. This necessitates repeated adjustments to the forklift's position, further hindering construction progress. Therefore, inventing a motor-driven cable reel-and-winding device to improve these problems has become a pressing issue for those skilled in the art. Utility Model Content

[0026] Please see Figure 1This utility model provides a technical solution: a motor-driven cable winding and unwinding device, comprising...

[0027] A base plate 4 is supported, and support frames 5 are installed on both sides of the base plate 4. A rotating rod 7 is installed on the top of the support frame 5 to limit rotation. A transmission belt is connected to one end of the rotating rod 7, and a motor 3 is connected to the other end of the transmission belt. A control box bracket 1 is set below the motor 3 and is located on one side of the base plate 4.

[0028] A cable reel placement rack 14 is provided in the middle of the support base plate 4. The cable reel placement rack 14 moves along the X, Y, and Z axes in the middle of the support base plate 4. The cable reel is placed above the telescopic cable reel placement rack 14. The cable reel placement rack 14 is used to support and move the cable reel, making it easy to install on the rotating rod 7 and avoiding repeated adjustments of the position by the forklift.

[0029] Please see Figure 3 and Figure 4 The rotating rod 7 is divided into two sections, and bearings 6 are respectively sleeved on the outside of the two sections of the rotating rod 7. The outer rings of the bearings 6 are respectively fixedly installed on the top of the support frame 5. The middle section of the two sections of the rotating rod 7 is connected to an intermediate rod through a sleeve connector 10. The sleeve connector 10 is used to splice the two rotating rods 7 and the intermediate rod to facilitate the installation of the cable reel.

[0030] Please see Figures 1 to 4 The support frame 5 is an isosceles trapezoid with a support rod in the middle. The middle support rod, together with the support rods on both sides, is fixedly connected to the support base plate 4 to improve the stability of the support.

[0031] The sleeve connector 10 includes an elastic sleeve 101. A connecting part 102 is provided on one side of the elastic sleeve 101. A bolt is provided through the middle of the connecting part 102. One side of the elastic sleeve 101 is limited and sleeved with one end of the rotating rod 7, and the other side of the elastic sleeve 101 is limited and sleeved with the intermediate rod. The bolt passes through the connecting parts 102 at both ends of the elastic sleeve 101 and is locked by nuts to lock the connecting parts 102. The elastic sleeve 101 connects the rotating rod 7 and the intermediate rod. The bolt connection is locked and easy to disassemble.

[0032] The control box bracket 1 is fixedly installed on one side of the support base plate 4. The control box bracket 1 has two layers. The bottom layer of the control box bracket 1 has the control box 2. The motor 3 is fixedly installed on the top layer of the control box bracket 1. The output end of the motor 3 is connected to a rotating rod 7 via a belt.

[0033] A guide seat 8 is fixedly connected above the rotating rod 7 near the motor 3, and a guide rod 9 is provided at the end of the guide seat 8. The guide seat 8 is located inside the support frame 5, and the guide rod 9 is arranged parallel to the rotating rod 7. The guide rod 9 is used for...

[0034] A rectangular through hole is provided in the middle of the support base plate 4. Electromagnetic slide rails 11 are fixedly installed on the inner walls of both ends of the rectangular through hole. A movable plate 12 is provided between the electromagnetic slide rails 11. The cable reel placement rack 14 is installed on the movable plate 12.

[0035] A sliding groove is provided in the middle of the movable plate 12, and an electric telescopic rod 13 is provided above the movable plate 12. A slide rail that matches the sliding groove in the middle of the movable plate 12 is provided at the bottom of the electric telescopic rod 13. The cable reel placement rack 14 is fixedly installed on the top of the electric telescopic rod 13.

[0036] The cable reel placement rack 14 is arc-shaped, and the slide groove in the middle of the moving plate 12 is perpendicular to the electromagnetic slide rail 11. The surface of the cable reel placement rack 14 is provided with a rubber layer to ensure that the cable is cushioned when the forklift places the cable reel, and also to increase friction and ensure the stability of the cable reel.

[0037] After motor 3 starts, its output end drives the rotating rod 7, which is close to motor 3, to rotate via a belt. The rotating rod 7 is divided into two sections, each sleeved on a bearing 6. The bearing 6 is fixed to the top of the support frame 5, allowing the rotating rod 7 to rotate stably and within a limited position above the support frame 5. The middle section of the two rotating rod sections 7 is connected to an intermediate rod via a sleeve connector 10. When the rotating rod 7 rotates, the intermediate rod rotates accordingly, thereby driving the cable reel to rotate and realize the winding and unwinding of the cable.

[0038] Controlling the electromagnetic slide rail 11 via control box 2 allows the moving plate 12 to move along the electromagnetic slide rail 11 within the rectangular through hole in the center of the supporting base plate 4 (movement in the X-axis direction), adjusting the lateral position of the cable reel placement rack 14 to facilitate forklift placement of the cable reel on the rack. Then, the worker pushes the cable reel to slide along the groove in the center of the moving plate 12 (movement in the Y-axis direction), while the electric telescopic rod 13 extends and retracts to move in the Z-axis direction, thereby adjusting the cable reel placement rack 14 to a suitable height and position, ensuring the center of the cable reel is aligned with the intermediate rod. Next, the intermediate rod is passed through the center of the cable reel and connected to the rotating rod 7 via the sleeve connector 10. Afterwards, the position of the cable reel placement rack 14 is readjusted to ensure it does not obstruct subsequent operations.

[0039] After the cable reel is placed on the cable reel holder 14 and connected to the intermediate rod, the guide rod 9 at the end of the guide seat 8 is inserted into the positioning hole of the cable reel (the guide rod 9 is inserted into the positioning hole of the cable reel by the displacement of the cable reel driven by the electromagnetic slide rail 11). The guide seat 8 is located inside the support frame 5 and the guide rod 9 is parallel to the rotating rod 7. When the rotating rod 7 rotates and drives the cable reel to rotate, the guide rod 9 plays a limiting role, keeping the cable reel rotating stably and preventing it from deviating or shaking during rotation, thus ensuring the smooth winding and unwinding of the cable.

[0040] Working principle: First, move the electric telescopic rod 13 on the slider and the cable reel placement rack 14 longitudinally until one end of the chute. At this point, the obstruction of the support frame 5 on the cable reel placement rack 14 is reduced. Use a forklift to place the cable reel smoothly on the cable reel placement rack 14. Then, pass the intermediate support rod through the center of the cable reel. Then, manually push the slider to adjust the position of the cable reel until it is directly below the rotating rod 7. Then, activate the electric telescopic rod 13 through the control button to raise the cable reel. At this time, pay attention to the position of the intermediate support rod. First, align one end of the intermediate support rod with one end of the rotating rod 7, using the sleeve connector 1. Connect the rotating rod 7 and the intermediate support rod. If there is a certain distance difference between the intermediate support rod and the rotating rod 7, the electromagnetic slide rail 11 can be activated by the control button to adjust the cable reel laterally, so that the distance between the intermediate support rod and the rotating rod 7 at one end is shortened. Then, connect them using the sleeve connector 10. Then, by moving the rotating rod 7 at the other end, manually adjust the position of the rotating rod 7 at the other end and connect it to the intermediate support rod through the sleeve connector 10. After the connection is completed, insert the guide rod 9 into the positioning hole. At this time, the docking operation is completed. Then, retract the electric telescopic rod 13, start the motor 3, and start the cable reel unloading or rewinding operation.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
