Description

Technical Field

[0001] This utility model relates to the field of cable winding and unwinding technology, and in particular to an end-shaft type winding and unwinding device for insulated flexible cables. Background Technology

[0002] Flexible insulated cables, also known as flexible mineral insulated cables, combine flexibility and fire resistance. They are a special type of cable that mainly uses inorganic materials, such as metallic copper and magnesium oxide powder. These materials themselves do not cause fires, nor can they burn or support combustion. Therefore, this type of cable can continue to work in fire conditions close to the melting point of copper.

[0003] An existing patent (application number 201922446044.8) discloses a cable winding and unwinding device, relating to the field of cable winding and unwinding technology. Specifically, it is a cable winding and unwinding device including a cable unwinding frame with a cable reel inside. This device features an outer frame inside the unwinding frame, with locking blocks inside the outer frame. When the cable reverses direction, gears at both ends of a second rotating shaft engage with the locking blocks inside the outer frame, effectively interrupting the reversed cable movement. This solves the problem of existing devices not being able to handle reversed cable movement. Furthermore, a first rotating shaft is fixedly connected inside the locking blocks, with a wrench fixedly installed at one end of the first rotating shaft through the outer frame. This allows manual control of the cable reel's direction by manually adjusting the wrench, thus enabling manual control of the cable winding and unwinding process and increasing the device's practicality.

[0004] The existing cable winding and unwinding mechanism is relatively heavy. Manual rotation is not only time-consuming and labor-intensive, but also lacks good adjustment during cable winding. The cable is prone to tangling at a certain point on the winding reel, resulting in uneven cable winding. Utility Model Content

[0005] Therefore, it is necessary to provide an end-shaft type cable winding and unwinding device for insulated flexible cables to address the technical problems that the cable winding and unwinding mechanism is relatively heavy, manual rotation is not only time-consuming and labor-intensive, and the cable is not well adjusted during winding, which makes it easy for the cable to get tangled at a certain position on the winding reel, resulting in uneven cable winding.

[0006] A spool-type take-up and unwinding device for insulated flexible cables includes a mounting base. Mounting plates are fixedly mounted on the lower front and lower rear ends of the mounting base. A controller is fixedly mounted on the upper left side of the mounting base. A sliding groove is formed in the middle of the upper end of the mounting base. An adjusting device is fixedly mounted at the right end of the sliding groove. A support seat is slidably mounted on the upper end of the sliding groove. A driving device is mounted on the upper and lower right ends of the support seat. A winding device is fixedly mounted at the right end of the driving device. A guiding device is fixedly mounted on the rear upper end of the mounting base. The driving device includes a first servo motor and a movable base. A first gear is fixedly mounted on the output end of the first servo motor. A mounting column is fixedly mounted on the right end of the movable base. A second gear is fixedly mounted on the left side of the outer surface of the mounting column. Two bolt holes are formed on the outer surface of the mounting column.

[0007] In one embodiment, the upper right end of the support base has a movable groove, and the movable base is rotatably installed in the movable groove. The lower right end of the support base has a mounting groove, and the first servo motor is fixedly installed in the lower right end of the support base through the mounting groove.

[0008] The first servo motor drives the first gear, which in turn drives the second gear and the mounting column on it. The mounting column then rotates on the support base via a movable seat, ultimately driving the mounting cylinder to rotate and retract the cable, thereby improving the cable retraction efficiency.

[0009] In one embodiment, the winding device includes a mounting cylinder with several slots in the middle of its outer surface. Limiting discs are inserted and fixedly installed at both the left and right ends of the mounting cylinder. Fixing bolts are installed at both the upper left and upper right ends of the mounting cylinder. The mounting cylinder is fixedly installed on the outer surface of the mounting column by the fixing bolts.

[0010] The slots on the outer surface of the mounting cylinder not only facilitate the clamping of the cable, but also make it easy to disassemble the mounting cylinder by loosening the fixing bolts.

[0011] In one embodiment, the guiding device includes a guide frame with four guide grooves at the front end. A plurality of ball bearings are rotatably installed on the inner wall of each of the four guide grooves. Fixing plates are fixedly installed on the lower left and lower right ends of the guide frame. Mounting screws are installed on the upper ends of the two fixing plates. The guide frame is fixedly installed on the upper rear end of the mounting base by the mounting screws.

[0012] Depending on the cable thickness, select a suitable guide groove on the guide frame. Then, pass the cable through the guide groove and wrap it around the outer surface of the mounting cylinder. When the cable is being wound up, the guide groove can limit the cable movement and prevent excessive swaying. In addition, the ball bearing design inside the guide groove also prevents the cable from having excessive friction with the guide groove.

[0013] In one embodiment, the adjustment device includes a second servo motor, a threaded rod is fixedly installed at the output end of the second servo motor, a slider is threadedly installed on the outer surface of the threaded rod, the threaded rod is rotatably installed in a slide groove, and the second servo motor is fixedly installed at the right end of the slide groove.

[0014] The second servo motor drives the threaded rod to rotate in the slide groove. At this time, the slider on the threaded rod slides in the slide groove, thereby adjusting the support seat and the mounting cylinder at the upper end of the slider, so that the cable can be more evenly distributed on the mounting cylinder when winding.

[0015] In one embodiment, the first gear is meshed with the lower end of the second gear.

[0016] In one embodiment, the movable groove is provided with lubricating oil.

[0017] In one embodiment, the fixing bolt and the bolt hole are of the same specification and are positioned vertically correspondingly.

[0018] In one embodiment, the widths of the four guide slots increase sequentially from top to bottom.

[0019] In one embodiment, the slider is slidably mounted in the groove, and the slider is fixedly mounted at the lower end of the support base.

[0020] The aforementioned end-shaft type take-up and unwinding device for insulated flexible cables, when taking up the insulated flexible cable, selects a suitable guide groove on the guide frame according to the cable's thickness. The cable is then passed through the guide groove and wound around the outer surface of the mounting cylinder on the take-up device. During take-up, the guide groove limits the cable's movement, preventing excessive cable sway. Furthermore, the ball bearing design within the guide groove prevents excessive friction between the cable and the guide groove. Next, a servo motor on the drive device drives a gear, which in turn drives a gear and its mounting post. The mounting post then... The movable seat rotates on the support base, ultimately driving the mounting cylinder to rotate and wind up the cable. This not only improves winding efficiency, but the slots on the outer surface of the mounting cylinder also facilitate cable clamping. Furthermore, loosening the fixing bolts on it allows for easy disassembly of the mounting cylinder. Additionally, during winding, the second servo motor on the adjusting device drives the threaded rod to rotate within the slide groove. Simultaneously, the slider on the threaded rod slides within the groove, thereby adjusting the support base and mounting cylinder at the upper end of the slider. This ensures that the cable is more evenly distributed on the mounting cylinder during winding, further improving the winding effect. Attached Figure Description

[0027] Please refer to the following: Figures 1 to 5 This utility model provides an end-shaft type take-up and unwinding device for insulated flexible cables, including a mounting base 1. Mounting plates 8 are fixedly installed on the lower front and lower rear ends of the mounting base 1. A controller 9 is fixedly installed on the upper left side of the mounting base 1. A sliding groove 6 is opened in the middle of the upper end of the mounting base 1. An adjusting device 5 is inserted and fixedly installed on the right end of the sliding groove 6. A support seat 7 is slidably installed on the upper end of the sliding groove 6. A driving device 2 is installed on the upper and lower right ends of the support seat 7. A winding device 3 is inserted and fixedly installed on the right end of the driving device 2. A guide device 4 is fixedly installed on the upper rear end of the mounting base 1. The driving device 2 includes a first servo motor 20 and a movable seat 21. A first gear 22 is fixedly installed on the output end of the first servo motor 20. A mounting column 23 is fixedly installed on the right end of the movable seat 21. A second gear 24 is inserted and fixedly installed on the left side of the outer surface of the mounting column 23. Two bolt holes 25 are opened on the outer surface of the mounting column 23.

[0028] The upper right end of the support base 7 has a movable groove 26, and the movable base 21 is rotatably installed in the movable groove 26. The lower right end of the support base 7 has a mounting groove 27, and the first servo motor 20 is fixedly installed in the lower right end of the support base 7 through the mounting groove 27. The first gear 22 is meshed with the lower end of the second gear 24. Lubricating oil is provided in the movable groove 26.

[0029] The first servo motor 20 drives the first gear 22, which in turn drives the second gear 24 and the mounting column 23 on it. The mounting column 23 then rotates on the support base 7 via the movable seat 21, which in turn drives the mounting cylinder 30 to rotate and retract the cable, thereby improving the cable retraction efficiency.

[0030] The winding device 3 includes a mounting cylinder 30. Several slots 31 are opened in the middle of the outer surface of the mounting cylinder 30. Limiting plates 33 are inserted and fixedly installed at the left and right ends of the mounting cylinder 30. Fixing bolts 32 are installed on the upper left and upper right parts of the mounting cylinder 30. The mounting cylinder 30 is fixedly installed on the outer surface of the mounting column 23 by the fixing bolts 32. The fixing bolts 32 and the bolt holes 25 have the same specifications and are corresponding vertically.

[0031] The slots 31 on the outer surface of the mounting cylinder 30 not only facilitate the clamping of the cable, but also make it easy to disassemble the mounting cylinder 30 by loosening the fixing bolts 32 thereon.

[0032] The guiding device 4 includes a guide frame 40, with four guide grooves 41 at the front end of the guide frame 40. Several ball bearings 42 are rotatably installed on the inner wall of each of the four guide grooves 41. Fixing plates 43 are fixedly installed on the lower left and lower right ends of the guide frame 40. Mounting screws 44 are installed on the upper ends of the two fixing plates 43. The guide frame 40 is fixedly installed on the upper rear end of the mounting base 1 by the mounting screws 44. The width of the four guide grooves 41 increases from top to bottom.

[0033] Depending on the thickness of the cable, a suitable guide groove 41 is selected on the guide frame 40. The cable is then passed through the guide groove 41 and wound around the outer surface of the mounting cylinder 30. When the cable is being wound up, the guide groove 41 can limit the cable movement and prevent excessive swaying. In addition, the design of the ball bearings 42 inside the guide groove 41 also prevents the cable from having excessive friction with the guide groove 41.

[0034] The adjustment device 5 includes a second servo motor 50. A threaded rod 51 is fixedly installed at the output end of the second servo motor 50. A slider 52 is threadedly installed on the outer surface of the threaded rod 51. The threaded rod 51 is rotatably installed in the slide groove 6. The second servo motor 50 is fixedly installed at the right end of the slide groove 6. The slider 52 is slidably installed in the slide groove 6 and is fixedly installed at the lower end of the support base 7.

[0035] All electrical equipment in this utility model is based on existing technology. All electrical equipment can operate normally during trial operation. The controller 9 is electrically connected to the first servo motor 20 and the second servo motor 50. When the first servo motor 20 is adjusted, the circuit is not affected. The second servo motor 50 drives the threaded rod 51 to rotate in the slide groove 6. At this time, the slider 52 on the threaded rod 51 slides in the slide groove 6, thereby adjusting the support seat 7 at the upper end of the slider 52 and the mounting cylinder 30, so that the cable can be more evenly distributed on the mounting cylinder 30 when winding.

[0036] This utility model provides an end-shaft type take-up and unwinding device for insulated flexible cables. First, the controller 9 is connected to an external power source. Then, based on the cable thickness, a suitable guide groove 41 is selected on the guide frame 40. The cable is then passed through the guide groove 41 and wound around the outer surface of the mounting cylinder 30 on the take-up device 3. During take-up, the guide groove 41 limits the cable's movement, preventing excessive cable sway. Furthermore, the design of the ball bearings 42 inside the guide groove 41 prevents excessive friction between the cable and the guide groove 41. Next, the first servo motor 20 on the drive device 2 drives the first gear 22, which in turn drives the second gear 24 and its mounting post 23. Then, the movable seat 21 rotates on the support seat 7, which ultimately drives the mounting cylinder 30 to rotate and wind up the cable. This not only improves the winding efficiency, but also the slot 31 on the outer surface of the mounting cylinder 30 facilitates the clamping of the cable. At the same time, the mounting cylinder 30 can be easily disassembled by loosening the fixing bolts 32 on it. In addition, while winding, the second servo motor 50 on the adjusting device 5 drives the threaded rod 51 to rotate in the slide groove 6. At this time, the slider 52 on the threaded rod 51 slides in the slide groove 6, thereby adjusting the support seat 7 and the mounting cylinder 30 at the upper end of the slider 52. This allows the cable to be more evenly distributed on the mounting cylinder 30 during winding, thereby improving the winding effect.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
