[0002] With the rapid development of the machinery industry, the application of large-scale mobile power supply equipment is becoming increasingly widespread. A cable winding device, such as a reel, provides power and control signals to large mobile devices. In power systems, communication networks, construction engineering, and the metallurgical industry, cable winding machines are required for the winding and unwinding of cables on reels. Existing cable winding machines are mostly moved manually, with the cable or wire tightly wound onto the drum via guide rails. Manual operation is inefficient, and to meet the needs of different industries, the outer diameter of the cable or wire has increased, and the transmission distance has lengthened, making manual dragging forward and backward extremely inconvenient and severely hindering the equipment's production efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a cable winding and unwinding device that reduces manual operation, greatly improves work efficiency, and provides a better user experience.

A main shaft is installed in the cylinder. The first driver is driven to one end of the main shaft. The guide rod and the second driver are both mounted on the mounting frame. The guide rod extends axially along the cylinder. The end of the main shaft away from the first driver is connected to the second driver. The cable unwinder is slidably mounted on the guide rod. One end of the third driver is connected to the second driver to form the power input end of the third driver. The other end of the third driver serves as the power output end for driving the cable unwinder to move left and right along the axial direction of the cylinder.

[0014] Compared with related technologies, the beneficial effects of this utility model are as follows:

[0015] I. This utility model achieves electric cable laying by adding a second driver and a third driver. Compared with manual operation, it reduces the time and cost of manually dragging and pulling cables, and is more efficient. Even if the transmission distance is longer, there is enough output torque to pull and pull the cable.

[0017] Third, after realizing electric cable laying, this utility model reduces the risk of surface damage caused by dragging the cable on the ground during the cable laying and winding process, as well as the risk of cable crushing and breaking due to untimely manual dragging, thus protecting the safety and reliability of the cable.

[0018] Fourth, after realizing electric cable laying, the installation of cables is more standardized and consistent, reducing errors caused by human factors and improving project quality and reliability. Attached Figure Description

[0023] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of the present invention can be combined with each other. For ease of description, the terms "upper," "lower," "left," and "right" appearing below only indicate that they correspond to the upper, lower, left, and right directions in the accompanying drawings and do not limit the structure.

[0024] like Figure 1 As shown, the cable winding and unwinding device provided in this embodiment includes a mounting frame 1, a spacer 2, a main shaft 3, a cylinder 6, a cable unwinder 8, a bearing assembly 9, a slip ring box 10, a protective cover 12, a second driver 13, a guide rod 14, and a first driver 17.

[0025] The mounting frame 1 includes two spaced-apart frames 101 and a mounting plate 105 connecting the two frames 101. The mounting frame 1 is a load-bearing component. Specifically, each frame 101 includes a first frame 102 and a second frame 103 connected together. The first frame 102 is a rectangular structure, and the second frame 103 is an isosceles trapezoid with diagonal bracing 104. The mounting plate 105 is bolted to the upper surface of the end of the first frame 102 away from the second frame 103.

[0026] The main shaft 3 passes through the cylinder 6, and a spacer 2 is provided between the main shaft 3 and the cylinder 6. The spacer 2 has a limiting function, preventing the main shaft 3 from deviating from the cylinder 6. The main shaft 3 carries the cylinder 6 and transmits power. This power comes from the first driver 17. The first driver 17 includes a motor 4 and a first reducer 5 connected to the motor 4. The motor 4 is mounted on one of the frames 101 via a mounting base, and the other frame 101 is mounted on a slip ring box 10 via a bearing assembly 9. The slip ring box 10 contains a slip ring. The slip ring box 10 provides power and signal lines for the cable, supplying power to the cable winding device. The cylinder 6 is placed between the two frames 101. The first reducer 5 is connected to one end of the main shaft 3 to drive the main shaft 3 to rotate. The other end of the main shaft 3 extends into the slip ring box 10 and is connected to the slip ring.

[0027] The second driver 13 includes a first drive wheel (not shown), a belt (not shown), a second drive wheel (not shown), and a second reducer 11. The first drive wheel is mounted on the main shaft 3 and moves with the main shaft 3. The input end of the second reducer 11 is connected to the second drive wheel. The output end of the second reducer 11 is equipped with the first sprocket 15 of the third driver 18. The first drive wheel and the second drive wheel are connected by the belt. The first drive wheel and the second drive wheel can also be replaced by sprockets, and the belt can also be replaced by a chain. The first drive wheel, the belt, and the second drive wheel are all covered by a protective cover 12, which is mounted on the mounting bracket 1.

[0028] The third drive 18 includes a second sprocket 7 and a chain 16. A first sprocket 15 is mounted on the power output end of the second reducer 11 of the second drive 13. Two second sprockets 7 are rotatably mounted on the upper side of the mounting plate 105 of the mounting bracket 1. The first sprocket 15 and the two second sprockets 7 are connected by the chain 16. A drive rod is fixedly mounted on one link of the chain 16, and a pulley (not shown) is provided at the end of the drive rod away from the chain 16.

[0029] The guide rod 14 has three parts (two at the top and one at the bottom), which are bolted to the lower side of the mounting plate 105. The cable tray 8 includes a slide 81, an upper roller 82 and a lower roller 83 rotatably mounted in the slide 81. The slide 81 includes two spaced-apart first upright plates 811 and a second upright plate 812 connecting the two first upright plates 811. The two first upright plates 811 have circular holes for the guide rod 14 to pass through. The upper roller 82 and the lower roller 83 are mounted between the two first upright plates 811 by a bracket (not labeled). The upper roller 82 and the lower roller 83 are sandwiched between the upper and lower sides of the guide rod 14.

[0030] The second upright plate 812 is provided with a drive hole 84, which is a vertically extending waist-shaped hole, and the pulley at the end of the drive rod is adapted to the drive hole 84.

[0031] The cable retractor 8 is equipped with cable routing holes. One end of the cable passes through the cable routing holes and wraps around the cylinder 6, while the other end of the cable extends out of the cable retractor 8. When retracting or unretracting the cable, the first drive 17 is activated for a first-stage reduction, causing the main shaft 3 to rotate. The power from the main shaft 3 is reduced by the second reducer 11, causing the chain 16 to rotate cyclically between the two second sprockets 7. When the chain 16 is working, the drive rod moves cyclically along with the chain 16. For example, when the drive rod rotates with the chain 16 to the upper section of the chain 16, the drive rod connected to the chain 16 pulls the slide 81 to the left or right. When the drive rod rotates with the chain 16 to the lower section of the chain 16, the drive rod connected to the chain 16 pulls the slide 81 to the right or left, thereby realizing the left and right movement of the cable retractor 8. The cable on the cable retractor 8 moves synchronously with the cylinder 6 to achieve retracting and unretracting, keeping the cable neat and orderly.

[0032] The cable winding and unwinding device provided by this utility model has the advantages of compact structure (reflected in the small space occupied by this type of drum), high stability, ability to wind and unwind long cables, greater output torque, and easy installation (it can now be fixed on the ground or platform in the operating area). The cable winding and unwinding device automatically winds and releases cables neatly through a cable tray, reducing manual operation and greatly improving work efficiency.

[0033] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
