An adjustable cable take-up and unwinding device

Abstract

This utility model belongs to the field of cable installation technology, specifically an adjustable cable winding and unwinding device, including an operating table with multiple wheels. A slider is slidably connected in a groove. A first fixed frame is fixed to the end of the connecting component, and a pair of rollers are rotatably connected to the first fixed frame. A handrail is fixed to the operating table. By fixing the connecting component to the slider, the first fixed frame to the connecting component, and the rollers rotatably connected to the first fixed frame, when the tension of the cable body itself is too low, the rollers press down on the cable body to maintain sufficient tension so that the cable body can be smoothly wound up by the take-up reel. This can reduce the situation where the cable body is in a loose state when wound up to the take-up reel due to insufficient tension during the winding process, thereby reducing the possibility of damage to the cable body due to friction between loose cable bodies during transportation.

Description

Technical Field

[0001] This utility model belongs to the field of cable installation technology, specifically an adjustable cable winding and unwinding device. Background Technology

[0002] Cables are wire products used to transmit electrical energy, signals, or realize the conversion of electromagnetic energy. They are usually composed of conductors, insulation layers, sheaths, etc., and are widely used in power, communication, construction, industry and other fields.

[0003] An adjustable cable reel-in / reel-out device is a piece of equipment used for cable laying, recycling, and storage. It features adjustable operation, easy operation, and high efficiency. It can reel in and reel in cables, facilitating cable transportation and storage.

[0004] Existing cable winding and unwinding devices generally use take-up reels to wind up and unwind cables. Through long-term use and observation, it has been found that when the cable surface tension is too low during winding, the cable is in a slack state. In this case, the cable wound onto the take-up reel is also relatively loose. When the loose cable is wound onto the reel, friction occurs between the cables during transportation, causing wear on the cable sheath. Furthermore, when unwinding the cable, the excessively loose cable can become knotted and tangled during the unwinding process. Therefore, to address these problems, an adjustable cable winding and unwinding device is proposed. Utility Model Content

[0005] To overcome the shortcomings of existing technology and address the problems of existing equipment, this utility model proposes an adjustable cable winding and unwinding device.

[0006] The technical solution adopted by this utility model to solve its technical problem is an adjustable cable take-up and unwinding device, including an operating table with multiple wheels. A pair of support plates are fixedly connected to the operating table, and a motor is fixedly connected to one of the support plates. The output end of the motor and the support plate are through-connected and rotatably connected. A take-up reel is fixedly connected to the motor output end, and the other end of the take-up reel is rotatably connected to the support plate. A cable body is mounted on the take-up reel. A pair of support columns are fixedly connected to the operating table, and a connecting plate is fixedly connected between the pair of support columns. The connecting plate has a sliding groove, and a slider is slidably connected within the groove. Multiple connecting components are fixedly connected to the slider. A first fixed frame is fixedly connected to the end of the component, and a pair of rollers are rotatably connected to the first fixed frame. A handrail is fixedly connected to the operating table. A connecting component is fixedly connected to the slider, and a first fixed frame is fixedly connected to the connecting component. Rollers are rotatably connected to the first fixed frame. When the tension of the cable body itself is too low, the rollers press down on the cable body to keep the cable body under sufficient tension so that it can be smoothly wound up by the take-up reel. This can reduce the situation where the cable body is in a loose state when wound up to the take-up reel due to the low tension of the cable body itself during the winding process, thereby reducing the possibility of damage to the cable body caused by friction between loose cable bodies during transportation.

[0007] Preferably, a fixed column is fixedly connected to the support plate, and a horizontal plate is fixedly connected between a pair of fixed columns. A plurality of connecting rods are provided on the horizontal plate, and the connecting rods and the horizontal plate are through-connected. A second fixed frame is fixedly connected to the end of the connecting rod. A first spring is fixedly connected between the horizontal plate and the second fixed frame. The connecting rod is located inside the first spring. A pressing roller is rotatably connected to the second fixed frame. By fixing the first spring between the horizontal plate and the second fixed frame, providing the connecting rod inside the first spring, and rotatably connecting the pressing roller to the second fixed frame, the pressing roller contacts and rotates with the cable body during use. This allows the pressing roller to press the cable body during winding, making the cable body wound onto the take-up reel more compact and further reducing the loosening of the cable body wound onto the take-up reel.

[0008] Preferably, a connecting strip is fixed to the first fixing frame, a brush plate is fixed to the connecting strip, and multiple brush bristles are fixed to the brush plate. By fixing multiple brush bristles to the brush plate, the surface of the cable body can be cleaned during use. This can reduce the damage to the protective layer of the cable body caused by friction between the sand and gravel and the cable body when the cable body is wound up outdoors.

[0009] Preferably, the connecting assembly includes a second spring, with one end of the second spring fixedly connected to the slider and the other end of the second spring fixedly connected to the first fixing frame. A first telescopic rod is provided inside the second spring, with both ends of the first telescopic rod fixedly connected to the slider and the first fixing frame, respectively. By fixing the second spring between the slider and the first fixing frame and providing the first telescopic rod inside the second spring, the second spring can be compressed when the cable body tension is high. This reduces the possibility of the cable body being damaged due to excessive tension caused by the rollers in place of the first fixing frame pressing down excessively on the cable body when the cable body tension is high.

[0010] Preferably, a pair of buffer blocks are fixedly connected to the first fixed frame. The buffer blocks are located between a pair of rollers. The buffer blocks are made of flexible material. By fixing the buffer blocks to the first fixed frame, the damage to the cable body caused by excessive friction due to direct contact between the cable body and the first fixed frame when the cable body moves during winding can be reduced.

[0011] Preferably, a pair of second telescopic rods are fixedly connected to the horizontal plate, and the other end of the second telescopic rod is fixedly connected to the second fixed frame. By fixing the second telescopic rod between the horizontal plate and the second fixed frame, the second telescopic rod is compressed and stretched during use, which can make the first spring more stable during use and reduce the shaking of the first spring during operation.

[0012] The advantages of this utility model are:

[0013] This utility model provides an adjustable cable take-up and unwinding device. A connecting component is fixedly connected to a slider, and a first fixed frame is fixedly connected to the connecting component. A roller is rotatably connected to the first fixed frame. When the tension of the cable body itself is too low, the roller presses down on the cable body to maintain sufficient tension so that the cable body can be smoothly wound up by the take-up reel. This can reduce the situation where the cable body is in a loose state when wound up to the take-up reel due to insufficient tension of the cable body itself during the winding process, thereby reducing the possibility of damage to the cable body caused by friction between loose cable bodies during transportation.

[0014] This utility model provides an adjustable cable take-up and unwinding device. A first spring is fixed between a horizontal plate and a second fixed frame, and a connecting rod is provided inside the first spring. A pressing roller is rotatably connected to the second fixed frame. During use, the pressing roller contacts and rotates with the cable body, which allows the pressing roller to press the cable body during the winding process, making the cable body wound onto the take-up reel more compact and further reducing the loosening of the cable body wound onto the take-up reel.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figures 1-5As shown, an adjustable cable take-up and unwinding device includes an operating platform 1 with multiple wheels 11. A pair of support plates 12 are fixedly connected to the operating platform 1. A motor 13 is fixedly connected to one of the support plates 12. The output end of the motor 13 is through-connected to the support plate 12 and rotatably connected. A take-up reel 14 is fixedly connected to the output end of the motor 13. The other end of the take-up reel 14 is rotatably connected to the support plate 12. A cable body 15 is mounted on the take-up reel 14. A pair of support columns 16 are fixedly connected to the operating platform 1. A connecting plate 17 is fixedly connected between the pair of support columns 16. The connecting plate 17 has a sliding groove 18. A slider 19 is slidably connected within the sliding groove 18. Multiple... A connecting component 110 is provided, with a first fixing frame 111 fixed to its end. A pair of rollers 112 are rotatably connected to the first fixing frame 111. A handrail 113 is fixed to the operating table 1. When the cable body 15 needs to be wound up, the worker holds the handrail 113 and pushes the operating table 1 to a suitable position. Then, the end of the cable body 15 is passed between the pair of rollers 112 and wound onto the take-up reel 14. At this time, the motor 13 is turned on by the control box 7 on the operating table 1. When the motor 13 is turned on, it drives the take-up reel 14 to rotate. When the take-up reel 14 rotates, it winds up the cable body 15. During the winding process, the position of the cable body 15 will change. At this time, the cable body 15 drives the slider 19 to move accordingly. When the slider 19 slides in the groove 18, the cable is wound up to different positions on the take-up reel 14. During the winding process of the cable body 15, when the tension of the cable body 15 is too low, the roller 112 presses down on the cable body 15. At this time, the roller 112 rotates and the tension of the cable body 15 increases. When the tension of the cable body 15 increases, the cable body 15 wound on the take-up reel 14 is in a taut state. When the cable body 15 wound on the take-up reel 14 is in a taut state, the take-up reel 14 can better wind up the cable body 15. When it is necessary to unwind the cable body 15, the slider 19 is moved to a position close to the support column 16 and then the cable body is pulled. The cable body 15 can be unwound at the end of the cable reel 15. A connecting component 110 is fixed to the slider 19, and a first fixing frame 111 is fixed to the connecting component 110. A roller 112 is rotatably connected to the first fixing frame 111. When the tension of the cable body 15 is too low, the roller 112 presses down on the cable body 15 to maintain sufficient tension so that it can be smoothly wound up by the take-up reel 14. This can reduce the situation where the cable body 15 is in a loose state when wound up to the take-up reel 14 due to insufficient tension. This can reduce the situation where the cable body 15 is damaged due to friction between loose cable bodies 15 during transportation.

[0024] Please see Figures 3-5 As shown, a fixed column 2 is fixedly connected to the support plate 12, and a horizontal plate 21 is fixedly connected between a pair of fixed columns 2. Multiple connecting rods 22 are provided on the horizontal plate 21, and the connecting rods 22 and the horizontal plate 21 are through-connected. A second fixed frame 23 is fixedly connected to the end of each connecting rod 22. A first spring 24 is fixedly connected between the horizontal plate 21 and the second fixed frame 23, and the connecting rod 22 is located inside the first spring 24. A pressing roller 25 is rotatably connected to the second fixed frame 23. When the take-up reel 14 winds up the cable body 15, the pressing roller 25 contacts the cable body 15 wound onto the take-up reel 14, further pressing the cable body 15 to make it more tightly packed on the take-up reel 14. When the take-up reel 14 rotates, the pressing roller 25 rotates accordingly. As the take-up reel 14 winds up more and more cable body 15, the thickness of the cable body 15 on the take-up reel 14 increases. At this time, the cable body 15... The pressing roller 25 generates pressure. When the pressing roller 25 is under force, the first spring 24 is compressed. At this time, the pressing roller 25 moves towards the horizontal plate 21. When the cable body 15 needs to be unwound, the volume of the cable body 15 on the take-up reel 14 gradually decreases. At this time, under the elastic force of the first spring 24, the pressing roller 25 is pushed towards the operating table 1. At this time, the pressing roller 25 is always in contact with the surface of the cable body 15. The first spring 24 is fixed between the horizontal plate 21 and the second fixed frame 23. A connecting rod 22 is provided in the first spring 24. The pressing roller 25 is rotatably connected to the second fixed frame 23. During use, the pressing roller 25 contacts the cable body 15 and rotates. This allows the pressing roller 25 to press the cable body 15 during the winding process, making the cable body 15 wound onto the take-up reel 14 more compact and further reducing the loosening of the cable body 15 wound onto the take-up reel 14.

[0025] Please see Figure 2 As shown, a connecting strip 3 is fixedly connected to the first fixing frame 111, and a brush plate 31 is fixedly connected to the connecting strip 3. Multiple brush bristles 32 are fixedly connected to the brush plate 31. When the cable body 15 located outdoors is wound up, the cable body 15 is passed between a pair of rollers 112. At this time, the surface of the cable body 15 comes into contact with the brush bristles 32. When the cable body 15 comes into contact with the brush bristles 32, the brush bristles 32 clean the surface of the cable body 15. By fixing multiple brush bristles 32 to the brush plate 31, the surface of the cable body 15 can be cleaned during use. This can reduce the damage to the protective layer on the cable body 15 caused by friction between the sand and gravel and the cable body 15 when the cable body 15 is wound up outdoors.

[0026] Please see Figure 4As shown, the connecting assembly 110 includes a second spring 4. One end of the second spring 4 is fixedly connected to the slider 19, and the other end of the second spring 4 is fixedly connected to the first fixing frame 111. A first telescopic rod 41 is provided inside the second spring 4. The two ends of the first telescopic rod 41 are fixedly connected to the slider 19 and the first fixing frame 111, respectively. When the surface tension of the cable body 15 is large enough to meet the winding requirements, the cable body 15 and the roller 112 come into contact. At this time, the cable body 15 pushes the first fixing frame 111 towards the connecting plate 17. When the first fixing frame 111 is pushed towards the connecting plate 17, the second spring 4 is compressed. By fixing the second spring 4 between the slider 19 and the first fixing frame 111, and providing the first telescopic rod 41 inside the second spring 4, the second spring 4 can be compressed when the tension of the cable body 15 is large. This reduces the situation where the first fixing frame 111 is in place when the tension of the cable body 15 is large, and the roller 112 excessively presses down on the cable body 15, causing the cable body 15 to be damaged due to excessive tension.

[0027] Please see Figures 2-5 As shown, a pair of buffer blocks 5 are fixedly connected to the first fixing frame 111. The buffer blocks 5 are located between a pair of rollers 112. The buffer blocks 5 are made of flexible material. When the cable body 15 is wound up by the take-up reel 14, the cable body 15 will move left and right. When the cable body 15 moves, the cable body 15 comes into contact with the pair of buffer blocks 5. At this time, the pair of buffer blocks 5 buffer the cable body 15. By fixing the buffer blocks 5 to the first fixing frame 111, the situation where the cable body 15 directly contacts the first fixing frame 111 and is damaged due to excessive friction when the cable body 15 moves during winding can be reduced.

[0028] Please see Figure 5 As shown, a pair of second telescopic rods 6 are fixedly connected to the horizontal plate 21. The other end of the second telescopic rods 6 is fixedly connected to the second fixed frame 23. When the cable body 15 is wound up to a certain volume, the cable body 15 squeezes the pressing roller 25. At this time, the first spring 24 is compressed. When the first spring 24 is compressed, the pair of second telescopic rods 6 are compressed accordingly. When the cable body 15 is unwound, when the volume of the cable body 15 on the take-up reel 14 decreases, the first spring 24 pushes the pressing roller 25 toward the take-up reel 14 under its own elastic force. At this time, the second telescopic rods 6 are stretched. By fixing the second telescopic rods 6 between the horizontal plate 21 and the second fixed frame 23, the second telescopic rods 6 are compressed and stretched during use, which can make the first spring 24 more stable during use and reduce the shaking of the first spring 24 during use.

[0029] Working principle: When it is necessary to reel in the cable body 15 on an outdoor site, the worker holds the handle 113 and pushes the operating table 1 to a suitable position. Then, the end of the cable body 15 is passed between a pair of rollers 112 and wound onto the take-up reel 14. At this time, the motor 13 is turned on through the control box 7 on the operating table 1. When the motor 13 is turned on, it drives the take-up reel 14 to rotate. As the take-up reel 14 rotates, it reels in the cable body 15. During the reeling process, the position of the cable body 15 changes. At this time, the cable body 15 drives the slider 19 to move. When the slider 19 slides in the groove 18, the cable is wound to different positions on the take-up reel 14. During the winding process, when the tension of the cable body 15 is too low, the roller 112 presses down on the cable body 15, causing the roller 112 to rotate and increasing the tension of the cable body 15. When the tension of the cable body 15 increases, the cable body 15 wound onto the take-up reel 14 is in a taut state. When the cable body 15 wound onto the take-up reel 14 is in a taut state, the take-up reel 14 can better wind up the cable body 15. When it is necessary to unwind the cable body 15, the slider 19 is moved to a position close to the support column 16, and then the end of the cable body 15 is pulled to unwind the cable body 15. When the take-up reel 14 winds up the cable body 15, the pressure roller 25 contacts the cable body 15 wound onto the take-up reel 14. The cable body 15 is further pressed to make it more tightly packed on the take-up reel 14. When the take-up reel 14 rotates, the pressing roller 25 rotates accordingly. As the take-up reel 14 winds up more and more cable body 15, the thickness of the cable body 15 on the take-up reel 14 increases. At this time, the cable body 15 exerts pressure on the pressing roller 25. When the pressing roller 25 is under force, the first spring 24 is compressed. At this time, the pressing roller 25 moves towards the horizontal plate 21. When it is necessary to unwind the cable body 15, the volume of the cable body 15 on the take-up reel 14 gradually decreases. At this time, under the elastic force of the first spring 24, the pressing roller 25 is pushed towards the operating table 1. At this time, the pressing roller 25 is always in contact with the surface of the cable body 15. When the cable body is located outdoors... During winding, the cable body 15 passes between a pair of rollers 112. At this time, the surface of the cable body 15 contacts the brush bristles 32. When the cable body 15 contacts the brush bristles 32, the brush bristles 32 clean the surface of the cable body 15. When the surface tension of the cable body 15 is large enough to meet the winding requirements, the cable body 15 contacts the rollers 112. At this time, the cable body 15 pushes the first fixing frame 111 towards the connecting plate 17. When the first fixing frame 111 is pushed towards the connecting plate 17, the second spring 4 is compressed. When the cable body 15 is wound by the take-up reel 14, the cable body 15 will move left and right. When the cable body 15 moves, the cable body 15 contacts a pair of buffer blocks 5. At this time, the pair of buffer blocks 5 cushion the cable body 15.When the cable body 15 is wound up to a certain volume, it squeezes the pressure roller 25, compressing the first spring 24. Simultaneously, the pair of second telescopic rods 6 are compressed. During the unwinding process, when the volume of the cable body 15 on the take-up reel 14 decreases, the first spring 24, under its own elastic force, pushes the pressure roller 25 towards the take-up reel 14, stretching the second telescopic rods 6. The compression and stretching of the second telescopic rods 6 during use makes the first spring 24 more stable and reduces wobbling during operation.
