Description

Technical Field

[0001] This invention belongs to the field of cable winding technology, and specifically relates to a cable winding and unwinding device. Background Technology

[0002] Cables are a general term for items such as optical cables and electrical cables. They are mainly composed of PVC plastic particles with a processed sheath and insulation, and copper wires of various specifications twisted together. Cables have many uses, mainly for control installation, connecting equipment, and transmitting electricity, and are a common and indispensable item in daily life. Because cables are live, their installation requires special care.

[0003] When cables are in use, they are laid on the ground for a long time. During the process of contact with the ground, the cables often come into contact with dirt and other substances, which adhere to the outer surface of the cables. Therefore, the existing technology uses a scraper to remove the dirt from the surface of the cables. However, when the cables are rolled up, they must pass through the scraper, but other parts of the cables that are not dirty will also pass through the scraper, causing dirt to get on the dirt-free parts as well, thus failing to achieve the purpose of thoroughly removing the dirt. Summary of the Invention

[0004] The purpose of this invention is to provide a cable winding and unwinding device to solve the problem in the prior art that the dirt on the surface of the cable is removed by a scraper. However, when the cable is wound up, it must pass through the scraper, but other parts of the cable that are not dirty will also pass through the scraper, causing the dirt-free parts to also get dirty, thus failing to achieve the effect of thoroughly removing the dirt.

[0005] A cable take-up and take-down device includes a take-up and take-down frame, a take-up mechanism, a swing mechanism, and a pre-treatment mechanism. The cable passes through the pre-treatment mechanism, the swing mechanism, and the take-up mechanism in sequence. The swing mechanism drives the cable to move back and forth so that the cable swings back and forth and is wound around the take-up mechanism. The swing mechanism also drives the cable to move back and forth on the pre-treatment mechanism to remove dirt from the surface of the cable.

[0006] Preferably, the swing mechanism includes a screw, a fixed seat, a fixed sleeve, a limiting plate, and a sliding rod. Two fixed seats are symmetrically fixedly connected to the front and rear sides of the take-up and put-down rack, and the screw is rotatably connected between the two fixed seats. The fixed sleeve is threaded onto the screw, and the fixed sleeve has limiting plates on both sides. The cable is limited between the limiting plates. One end of the screw is fixedly connected to the output shaft of the drive motor. A sliding rod is also fixedly connected between the two fixed seats. The sliding rod passes through the limiting plate and is slidably connected to the limiting plate. The fixed sleeve drives the cable to swing back and forth on the pretreatment mechanism, and the screw drives the pretreatment mechanism to rotate up and down.

[0007] Preferably, the pretreatment mechanism includes a fixed plate, a bracket, an upper brush, a lower brush, a water tank, and a connecting assembly. Two brackets are symmetrically fixedly connected to both sides of the take-up and take-down rack, and a fixed plate parallel to the screw is rotatably connected between the two brackets. The upper and lower sides of the fixed plate are respectively provided with upper brush and lower brush. The cable moves back and forth on the upper brush to remove dirt. The water tank is located below the fixed plate and has an opening at the top. The lower brush is located inside the water tank and is soaked in water. The connecting assembly is provided between the screw and the fixed plate, and the fixed plate is reversed by means of the connecting assembly.

[0008] Preferably, a rotating shaft passes through the middle of the fixing plate, and both ends of the rotating shaft protrude from the brackets on both sides. A connecting assembly is provided between the screw and the end of the rotating shaft on the same side. The connecting assembly includes an incomplete gear and a driven gear. The end of the screw is coaxially fixedly connected to the incomplete gear, and the end of the rotating shaft is coaxially fixedly connected to the driven gear. The incomplete gear and the driven gear mesh intermittently, and the rotation of the incomplete gear drives the rotating shaft to rotate intermittently. A support assembly is provided below the rotating shaft to keep the rotating shaft balanced.

[0009] Preferably, the support assembly includes magnet one, magnet two, magnet three, and telescopic rods. Telescopic rods are symmetrically arranged on both sides of the water tank. An arc-shaped block is fixedly connected to the movable end of the telescopic rod, and the arc-shaped block presses against the bottom of the rotating shaft. Magnet one is embedded in the inner wall of the arc-shaped block. Magnet two and magnet three are embedded in the upper and lower sides of the rotating shaft. Magnet two and magnet three are attracted to magnet one.

[0010] Preferably, the telescopic rod includes a fixed rod, a movable rod, and an abutment spring. The fixed rod is hollow inside, and the movable rod is inserted into the inside of the fixed rod. The abutment spring is fixedly connected between the inner bottom of the fixed rod and the outer bottom of the movable rod.

[0011] Preferably, a pressure rod is fixedly connected between the two brackets. The pressure rod is located above the upper brush bristles and presses the cable inside the upper brush bristles. A connecting rod is fixedly connected between the two limiting plates. An L-shaped scraper is fixedly connected to the end of the connecting rod. The horizontal part of the L-shaped scraper is located inside the water tank. The screw drives the L-shaped scraper to move back and forth inside the water tank to clean the lower brush bristles by means of the L-shaped scraper.

[0012] Preferably, the winding mechanism includes a winding shaft, a winding wheel, a winding motor, a transmission belt, and a drive wheel. The winding shaft is rotatably connected between the two sides of the take-up and untake-down frame by means of bearings, and the winding wheel is fixedly connected to one end of the winding shaft. The winding motor is fixedly connected to the bottom of the take-up and untake-down frame, and the drive wheel is fixedly connected to the output shaft of the winding motor. The transmission belt connects the drive wheel and the winding wheel.

[0013] The present invention has the following advantages:

[0014] This invention utilizes the rotation of a screw to drive a fixed sleeve to move back and forth along the screw. The cable can be confined between the limiting plates on both sides of the fixed sleeve, thereby causing the cable to move with the limiting plates. During subsequent winding, the oscillating cable ensures it is evenly wound onto the winding mechanism, preventing it from concentrating in the center. Therefore, the screw rotation can intermittently drive the rotating shaft, causing the fixed plate to flip up and down. As the cable oscillates over the surface of the upper brush bristles, it moves to different positions on the upper brush bristles, allowing the bristles at different locations to clean the cable and preventing dirt from accumulating in the same spot. The fixing plate can flip up and down, so the upper brush bristles can rotate intermittently into the water tank. The back-and-forth movement of the limiting plate can also drive the L-shaped scraper to move back and forth. The L-shaped scraper scrapes the upper brush bristles located inside the water tank back and forth, and the lower brush bristles move to the bottom of the cable. The clean lower brush bristles are used to clean the cable. The upper brush bristles are cleaned in the water tank. When the fixing plate flips again, the cleaned upper brush bristles can be used to clean the cable again, so that the cable is cleaned more thoroughly. This invention can drive the cable to move back and forth on the pretreatment mechanism through the swing mechanism, thereby using different positions of the upper brush bristles to remove the dirt on the surface of the cable, and at the same time clean the dirt on the surface of the lower brush bristles.

[0026] The following detailed description of the embodiments, with reference to the accompanying drawings, will further illustrate the specific implementation of the present invention, in order to help those skilled in the art to have a more complete, accurate, and in-depth understanding of the inventive concept and technical solution of the present invention.

[0027] like Figure 1-5 The cable winding and unwinding device shown includes a winding and unwinding frame 1, a winding mechanism 5, a swinging mechanism 4, and a pre-treatment mechanism 2. The cable passes through the pre-treatment mechanism 2, the swinging mechanism 4, and the winding mechanism 5 in sequence. The swinging mechanism 4 drives the cable to move back and forth so that the cable swings back and forth and is wound around the winding mechanism 5. The swinging mechanism 4 also drives the cable to move back and forth on the pre-treatment mechanism 2 to remove the dirt from the surface of the cable.

[0028] The swing mechanism 4 includes a screw 41, a fixed base 40, a fixed sleeve 43, a limiting plate 44, and a sliding rod 45. Two fixed bases 40 are symmetrically fixedly connected to the front and rear sides of the take-up and put-down rack 1, and the screw 41 is rotatably connected between the two fixed bases 40. The fixed sleeve 43 is threadedly connected to the screw 41, and the fixed sleeve 43 has limiting plates 44 on both sides. The cable is limited between the limiting plates 44. One end of the screw 41 is fixedly connected to the output shaft of the drive motor 42. The sliding rod 45 is also fixedly connected between the two fixed bases 40. The sliding rod 45 passes through the limiting plate 44 and is slidably connected to the limiting plate 44. The fixed sleeve 43 drives the cable to swing back and forth on the pretreatment mechanism 2, and the screw 41 drives the pretreatment mechanism 2 to rotate up and down and change direction.

[0029] The drive motor 42 is a reversible motor. The rotation of the drive motor 42 can drive the screw 41 to rotate. The surface of the screw 41 is connected to the fixed sleeve 43 by a thread. Therefore, the rotation of the screw 41 can drive the fixed sleeve 43 to move back and forth along the screw 41. A slide rod 45 parallel to the screw 41 is provided between the two fixed seats 40. The slide rod 45 passes through the limiting plates 44 on both sides of the fixed sleeve 43. This allows the fixed sleeve 43 to move horizontally. The cable is close to the bottom of the fixed sleeve 43 and close to the top of the slide rod 45. Thus, the cable can be limited between the limiting plates 44 on both sides. The limiting plates 44 move with the fixed sleeve 43, which in turn can drive the cable to move with the limiting plates 44. The swinging cable can be evenly wound on the upper winding mechanism 5 during the subsequent winding, avoiding the cable from being concentrated in the middle of the winding mechanism 5.

[0030] The pretreatment mechanism 2 includes a fixed plate 22, a bracket 20, an upper brush 23, a lower brush 24, a water tank 25, and a connecting component 26. Two brackets 20 are symmetrically fixedly connected to both sides of the take-up and take-down rack 1, and the fixed plate 22, which is parallel to the screw 41, is rotatably connected between the two brackets 20. The upper and lower sides of the fixed plate 22 are respectively provided with upper brush 23 and lower brush 24. The cable moves back and forth on the upper brush 23 to remove dirt. The water tank 25 is located below the fixed plate 22 and has an opening at the top. The lower brush 24 is located inside the water tank 25 and is soaked in water. The connecting component 26 is provided between the screw 41 and the fixed plate 22, and the fixed plate 22 can be reversed by means of the connecting component 26. A rotating shaft 21 passes through the middle of the fixed plate 22, and the two ends of the rotating shaft 21 pass through the brackets 20 on both sides respectively. A connecting component 26 is provided between the screw 41 and the end of the rotating shaft 21 on the same side. The connecting component 26 includes an incomplete gear 27 and a driven gear 28. The end of the screw 41 is coaxially fixedly connected to the incomplete gear 27, and the end of the rotating shaft 21 is coaxially fixedly connected to the driven gear 28. The incomplete gear 27 and the driven gear 28 mesh intermittently, and the rotation of the incomplete gear 27 drives the rotating shaft 21 to rotate intermittently. A support component 3 is provided below the rotating shaft 21 to keep the rotating shaft 21 balanced.

[0031] The upper and lower sides of the fixing plate 22 are respectively provided with upper brush bristles 23 and lower brush bristles 24, with the lower brush bristles 24 disposed inside the water tank 25. The screw 41 is connected to the rotating shaft 21 inside the fixing plate 22 through an incomplete gear 27 and a driven gear 28. Therefore, the rotation of the screw 41 can intermittently drive the rotating shaft 21 to rotate, thereby causing the fixing plate 22 to flip up and down. When the fixing plate 22 is in a horizontal state, the cable passes over the surface of the upper brush bristles 23. Due to the swinging of the cable, the cable can move to different positions of the upper brush bristles 23, thereby utilizing... Cleaning the cable with bristles at different locations prevents dirt from accumulating in the same spot on the upper bristles 23, resulting in a cleaner cable cleaning later. Since the fixing plate 22 can flip up and down, the upper bristles 23 can rotate intermittently into the water tank 25, while the lower bristles 24 move to the bottom of the cable. The clean lower bristles 24 are used to clean the cable, and the upper bristles 23 are cleaned in the water tank 25. When the fixing plate 22 flips up again, the cleaned upper bristles 23 can be used to clean the cable again, resulting in a more thorough cleaning of the cable.

[0032] The support assembly 3 includes a first magnet 34, a second magnet 35, a third magnet 36, and a telescopic rod 30. The telescopic rods 30 are symmetrically arranged on both sides of the water tank 25. The movable end of the telescopic rod 30 is fixedly connected to an arc-shaped block 37, and the arc-shaped block 37 presses against the bottom of the rotating shaft 21. The first magnet 34 is embedded in the inner wall of the arc-shaped block 37. The second magnet 35 and the third magnet 36 are embedded in the upper and lower sides of the rotating shaft 21. The second magnet 35 and the third magnet 36 are attracted to the first magnet 34.

[0033] The function of the support component 3 is to ensure the stability of the fixed plate 22 when the incomplete gear 27 and the driven gear 28 are not meshed, so that the cable can be stably contacted by the upper brush bristles 23. Therefore, a telescopic rod 30 is set inside the water tank 25. The telescopic rod 30 includes a fixed rod 31, a movable rod 32, and a resisting spring 33. The fixed rod 31 is hollow inside, and the movable rod 32 is inserted into the fixed rod 31. The resisting spring 33 is fixedly connected between the inner bottom of the fixed rod 31 and the outer bottom of the movable rod 32. Under normal conditions, the resisting spring 33 is in a compressed state. The resisting spring 33 drives the arc-shaped block 37 to press tightly against the bottom of the rotating shaft 21. The resisting spring 33 and the arc-shaped block 37 can apply a certain pressure to the rotating shaft 21 to prevent the rotating shaft 21 from rotating. At the same time, the attraction between the second magnet 35 and the third magnet 36 and the first magnet 34 keeps the rotating shaft 21 in balance.

[0034] A pressure rod 29 is fixedly connected between the two brackets 20. The pressure rod 29 is located above the upper brush bristles 23 and presses the cable inside the upper brush bristles 23. A connecting rod 46 is fixedly connected between the two limiting plates 44. An L-shaped scraper 47 is fixedly connected to the end of the connecting rod 46. The horizontal part of the L-shaped scraper 47 is located inside the water tank 25. The screw 41 drives the L-shaped scraper 47 to move back and forth inside the water tank 25 to clean the lower brush bristles 24 by means of the L-shaped scraper 47.

[0035] The function of the pressure rod 29 is to press the cable inside the upper brush bristles 23, so that the friction between the cable and the upper brush bristles 23 is greater when the cable moves, and the cleaning is more thorough. The back-and-forth movement of the limiting plate 44 can also drive the L-shaped scraper 47 to move back and forth. The L-shaped scraper 47 scrapes the lower brush bristles 24 located inside the water tank 25 back and forth, thereby removing the dirt on the surface of the lower brush bristles 24. After the lower brush bristles 24 are flipped over and placed above the fixing plate 22, the cleaned lower brush bristles can clean the cable more thoroughly.

[0036] The winding mechanism 5 includes a winding shaft 50, a winding wheel 54, a winding motor 51, a transmission belt 53, and a drive wheel 52. The winding shaft 50 is rotatably connected between the two sides of the take-up and untake-down frame 1 by means of bearings, and the winding wheel 54 is fixedly connected to one end of the winding shaft 50. The winding motor 51 is fixedly connected to the bottom of the take-up and untake-down frame 1, and the drive wheel 52 is fixedly connected to the output shaft of the winding motor 51. The transmission belt 53 connects the drive wheel 52 and the winding wheel 54.

[0037] The winding motor 51 can drive the winding shaft 50 to rotate using the drive wheel 52, the winding wheel 54, and the transmission belt 53. One end of the cable is fixed on the winding shaft 50, and the cable can be stably wound onto the surface of the winding shaft 50 as the winding shaft 50 rotates.

[0038] Working principle: The drive motor 42 is a reversible motor. The rotation of the drive motor 42 can drive the screw 41 to rotate. The surface of the screw 41 is connected to the fixed sleeve 43 by a thread. Therefore, the rotation of the screw 41 can drive the fixed sleeve 43 to move back and forth along the screw 41. A slide rod 45 parallel to the screw 41 is provided between the two fixed seats 40. The slide rod 45 passes through the limiting plates 44 on both sides of the fixed sleeve 43, so that the fixed sleeve 43 can move horizontally. The cable is close to the bottom of the fixed sleeve 43 and above the slide rod 45. Thus, the cable can be confined between the limiting plates 44 on both sides. 44 moves with the fixed sleeve 43, which in turn drives the cable to move with the limiting plate 44. The swinging cable can be evenly wound onto the upper winding mechanism 5 during subsequent winding, preventing the cable from concentrating in the middle of the winding mechanism 5. The upper and lower sides of the fixed plate 22 are respectively provided with upper bristles 23 and lower bristles 24, with the lower bristles 24 set inside the water tank 25. The screw 41 is connected to the rotating shaft 21 inside the fixed plate 22 through an incomplete gear 27 and a driven gear 28. Therefore, the rotation of the screw 41 can intermittently drive the rotating shaft 21 to rotate, thereby causing the fixed plate 22 to flip up and down. When the fixed plate 22 is in a horizontal position, the cable passes over the surface of the upper brush bristles 23. Due to the oscillation of the cable, it can move to different positions on the upper brush bristles 23, thus cleaning the cable using bristles at different positions. This prevents dirt from accumulating in the same spot on the upper brush bristles 23, resulting in a cleaner cable cleaning in subsequent uses. Because the fixed plate 22 can flip up and down, the upper brush bristles 23 can intermittently rotate into the water tank 25, while the lower brush bristles 24 move to the underside of the cable. The clean lower brush bristles 24 are used to clean the cable, while the upper brush bristles 23 are cleaned in the water tank 25. The fixed plate 22 is then repositioned. When flipped over again, the cleaned upper brush bristles 23 can be used to clean the cable again, making the cable cleaner. The function of the pressure rod 29 is to press the cable into the upper brush bristles 23, so that the friction between the cable and the upper brush bristles 23 is greater when the cable moves, and the cleaning is more thorough. The back-and-forth movement of the limit plate 44 can also drive the L-shaped scraper 47 to move back and forth. The L-shaped scraper 47 scrapes the lower brush bristles 24 located inside the water tank 25 back and forth, thereby removing the dirt on the surface of the lower brush bristles 24. After the lower brush bristles 24 are flipped over above the fixing plate 22, the cleaned lower brush bristles can clean the cable even more thoroughly.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, are all within the protection scope of the present invention.
