[0001] This utility model belongs to the field of wire winding technology, specifically relating to a cable winding reel with corrugated tube. Background Technology

[0002] In many applications, to improve cable safety, corrugated conduits are needed to encase the cable. Currently, this is usually done manually by pulling a steel wire to thread the cable through one end of the corrugated conduit, and then manually winding the conduit. This method of threading cables through corrugated conduits is labor-intensive and inefficient. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A cable winding reel for passing through corrugated pipes includes a frame, on which a fixed reel and a drive motor for driving the fixed reel to rotate are rotatably connected. A winding wheel is coaxially connected to the fixed reel for winding corrugated pipes. The drive motor and the winding wheel are located on opposite sides of the fixed reel. A hollow shaft is vertically connected to the fixed reel on the side of the drive motor. The hollow shaft is rotatably connected to the frame via a bearing. A through hole corresponding to the center hole of the hollow shaft is formed on the fixed reel. The winding wheel includes a fixed arc plate and two movable arc plates. The fixed arc plate is fixedly connected to the side of the fixed reel facing away from the drive motor. The two movable arc plates are respectively hinged to the two sides of the fixed arc plate. The sum of the central angles corresponding to the fixed arc plate and the two movable arc plates is less than 360 degrees. °, so that the fixed arc plate and the two movable arc plates form a cylindrical structure with a notch. The center of the arc surface of the fixed arc plate is located on the central axis of the hollow shaft. The output shaft of the drive motor passes through the through hole and is inserted into the winding wheel. The output shaft is coaxial with the hollow shaft. Two cams are fixedly connected to the output shaft in sequence along the axial direction. The major axis of the two cams is offset from each other along the circumference of the output shaft. A wheel seat is connected to the inner wall of the two movable arc plates respectively. A roller is connected to the two wheel seats respectively. The two rollers abut against the two cams one by one. The two movable arc plates are connected to each other by a tension spring. The tension spring drives the two movable arc plates to move closer together to close the notch. The two rollers are located on the same side of the major axis of the two cams. The two rollers reciprocate on the arc surface on the major axis side of the corresponding cam.

[0005] As a preferred embodiment, any fixed arc plate and the movable arc plate are hinged to each other via a hinge pin located on one side of the concave arc surface.

[0006] As a preferred embodiment, the fixed disc is provided with guide traction holes that correspond one-to-one with the two movable arc plates. The end faces of the two movable arc plates opposite to the fixed disc are respectively connected to guide shafts that are inserted into the corresponding guide traction holes. The guide traction holes are waist-shaped holes, and the curvature of the guide traction holes is adapted to the swing trajectory of the movable arc plates.

[0007] As a preferred embodiment, the top of the output shaft of the drive motor is also detachably connected to a movable disc, which slides against the end of the winding wheel away from the fixed disc.

[0008] As a preferred embodiment, the central axis of the winding wheel is horizontally set, the frame is horizontally rotatably connected to one end of a swing arm, the other end of the swing arm is horizontally rotatably connected to one end of a connecting arm, and the other end of the connecting arm is rotatably connected to a movable disc.

[0009] As a preferred embodiment, the connecting arm is connected to a downwardly extending movable leg, and the lower end of the movable leg is connected to a wheel, which elastically abuts against the ground.

[0010] As a preferred embodiment, a drive shaft coaxial with the output shaft is vertically connected to the side of the movable disc facing the output shaft. The drive shaft and output shaft have opposing and staggered drive teeth at their opposite ends. Transmission is achieved through the meshing of these drive teeth. A threaded hole is located at the center of the output shaft. A screw is rotatably connected to the movable disc, passing through the movable disc and threaded into the threaded hole at the end of the output shaft. A stop is fixedly connected to the other end of the screw, located on the side of the movable disc opposite to the drive shaft, and a handwheel is connected to the stop. The beneficial effects of this utility model are as follows: The cable winding reel of this utility model divides the winding wheel into a movable arc plate and a fixed arc plate, which can change the outer diameter of the winding wheel. During winding, the outer circumference of the winding wheel is in a large or maximum state. After winding is completed, the outer circumference of the winding wheel is reduced, creating a gap between the winding wheel and the wound material, which allows the material to be easily removed from the winding wheel. This utility model uses rollers installed on the inner walls of the two movable arc plates, and cams corresponding to the rollers are installed on the output shaft. Tension springs are used to pull the two movable arc plates together, so that the rotation of the cams can drive the two movable arc plates to expand or contract. This simplifies the drive structure for changing the outer circumference of the winding wheel and improves the convenience for users when using the cable winding reel. Attached Figure Description

[0012] The specific implementation scheme of this utility model will now be described in detail with reference to the accompanying drawings. Example 1

[0013] like Figure 1 The cable winding reel shown includes a frame 1, on which a fixed reel 2 and a drive motor 3 are rotatably connected. A winding wheel 4 is coaxially connected to the fixed reel 2 for winding the corrugated tubing. The drive motor 3 and the winding wheel 4 are located on opposite sides of the fixed reel 2. A hollow shaft 5 is vertically connected to the fixed reel 2 on one side of the drive motor 3. The hollow shaft 5 is rotatably connected to the frame 1 via a bearing 6. A through hole 7 corresponding to the center hole of the hollow shaft 5 is provided on the fixed reel 2. Figure 2 and Figure 3As shown, the winding wheel 4 includes a fixed arc plate 401 and two movable arc plates 402. The fixed arc plate 401 is fixedly connected to the side of the fixed disc 2 facing away from the drive motor 3. The two movable arc plates 402 are respectively hinged to both sides of the fixed arc plate 401. The sum of the central angles corresponding to the fixed arc plate 401 and the two movable arc plates 402 is less than 360°, so that the fixed arc plate 401 and the two movable arc plates 402 form a cylindrical structure with a notch 8. The center of the arc surface of the fixed arc plate 401 is located on the central axis of the hollow shaft 5. The output shaft 301 of the drive motor 3 passes through the through hole 7 and is inserted into the winding wheel 4. The hollow shaft 5 is coaxially arranged, and two cams 9 are fixedly connected in sequence along the axial direction on the output shaft 301 located inside the winding wheel 4. The major axis of the two cams 9 is offset from each other along the circumference of the output shaft 301. A wheel seat 10 is connected to the inner wall of the two movable arc plates 402 respectively, and a roller 11 is connected to each of the two wheel seats 10. The two rollers 11 abut against the two cams 9 one by one. The two movable arc plates 402 are connected to each other by a tension spring 12. The tension spring 12 drives the two movable arc plates 402 to move closer to each other to close the notch 8. The two rollers 11 are located on the same side of the major axis of the two cams 9, and the two rollers 11 reciprocate on the arc surface on the corresponding major axis side of the cam 9.

[0014] In this embodiment, as Figure 2 and Figure 3 As shown, both cams 9 are elliptical. When the output shaft 301 rotates, it drives the cams 9 to rotate. In the initial stage of rotation, the cams 9 will form relative motion with the rollers 11. When the two rollers 11 move synchronously towards the short diameter end of the corresponding cam 9, the adjacent ends of the two movable arc plates 402 move closer to each other, and the notch 8 gradually shrinks. The outer circumference of the entire winding wheel 4 shrinks. When the two rollers 11 move synchronously towards the long diameter end of the corresponding cam 9, the two movable arc plates 402 are spread out until they are tightly pressed against the fixed arc plate 401 to form a winding wheel with a perfect outer circle and a notch 8. Due to the restriction of the fixed arc plate 401, the two movable arc plates 402 stop expanding when they expand to the maximum position. At this time, the rollers 11 have not yet reached the long diameter end of the cam 9. When the cam 9 continues to rotate in the original direction of motion, it drives the rollers 11 and the entire winding wheel 4 to rotate.

[0015] The use of an elliptical cam 9 allows the winding wheel 4 to be rotated in both directions to extend its outer circumference to the maximum, thereby improving its applicability and ease of operation.

[0016] Any fixed arc plate 401 and the movable arc plate 402 are hinged to each other by a hinge pin 403 located on one side of the concave arc surface.

[0017] To reduce the load on the fixed arc plate 401 and improve its stability, such as Figure 4As shown, in this preferred embodiment, the fixed disc 2 is provided with guide traction holes 13 corresponding to the two movable arc plates 402. Guide shafts 14, inserted into the corresponding guide traction holes 13, are respectively connected to the end faces of the two movable arc plates 402 opposite to the fixed disc 2. The guide traction holes 13 are oblong holes, and their curvature is adapted to the swing trajectory of the movable arc plates 402. When the two movable arc plates 402 rotate, the fixed disc 2 can be driven to rotate through the guide shafts 14 inserted into the guide traction holes 13, thereby reducing the torque experienced by the fixed arc plate 401 in driving the fixed disc 2 to rotate. Furthermore, preferably, when the movable arc plates 402 expand to the point where the outer circumference of the winding wheel 4 is a perfect circle, the two guide shafts 14 just abut against one end of the corresponding guide traction hole 13. The guide limiting holes 13 restrict the swing amplitude of the movable arc plates 402, reducing the force on the hinge shaft 403 and improving the overall stability of the winding wheel 4.

[0018] like Figure 1 As shown, a movable disc 15 is detachably connected to the top end of the output shaft 301 of the drive motor 3, and the movable disc 15 slides against the end of the winding wheel 4 away from the fixed disc 2.

[0019] Combination Figure 1 and Figure 5 The winding reel 4 has its central axis set horizontally. The frame 1 is horizontally rotatably connected to one end of a swing arm 16, and the other end of the swing arm 16 is horizontally rotatably connected to one end of a connecting arm 17. The other end of the connecting arm 17 is rotatably connected to the movable disc 15. The swing arm 16 and the connecting arm 17 support the movable disc 15 to prevent the output shaft 301 from wobbling due to the gravity of the movable disc 15.

[0020] like Figure 1 In this embodiment, a downwardly extending movable support leg 18 is preferably connected to the connecting arm 17. The lower end of the movable support leg 18 is connected to a wheel 19, which elastically abuts against the ground. The movable support leg 18 also supports the movable disc 15 and prevents the swing arm 16 and the connecting arm 17 from twisting.

[0021] like Figure 6 and Figure 7As shown, a drive shaft 20, coaxial with the output shaft 301, is vertically connected to the side of the movable disc 15 facing the output shaft 301. The drive shaft 20 and the output shaft 301 are respectively provided with drive teeth 21 extending in opposite directions and staggered from each other. The drive shaft 20 and the output shaft 301 achieve transmission through the meshing of the drive teeth 21. A threaded hole 22 is opened in the center of the output shaft 301. A screw 23 is rotatably connected to the movable disc 15. The screw 23 passes through the movable disc 15 and is threadedly connected to the threaded hole 22 at the end of the output shaft 301. A stop block 24 is fixedly connected to the other end of the screw 23. The stop block 24 is located on the side of the movable disc 15 opposite to the drive shaft 301. A handwheel 25 is connected to the stop block 24.

[0022] The working process of this embodiment is as follows: one end of the material to be wound is fixed on the fixed disc 2 or the fixed arc plate 401 or movable arc plate 402 of the winding wheel 4. Then, the drive motor 3 is started. The output shaft 301 of the drive motor 3 drives the cam 9 to rotate. The cam 9 pushes the two movable arc plates 402 outward to the maximum diameter of the winding wheel 4 through the two rollers 11. Then, the material is wound. The wound material needs to have a certain tension to keep the two movable arc plates 402 in the expanded state. After the material is wound, the drive motor 3 is stopped. The winding wheel 4 is rotated slightly so that the two movable arc plates 402 are pulled inward under the pull of the tension spring 12, so that the coiled wire that was originally tightly wound on the winding wheel 4 is loosened from the winding wheel 4. Then, the wire is taken off from the end of the winding wheel 4 away from the fixed disc 2 and bundled.

[0023] When the aforementioned cable winding reel with a corrugated tube is equipped with a movable disc 15, the movable disc 15 is installed on the output shaft 301 before winding the wire, and the movable disc 15 is removed from the output shaft 301 when the coiled wire needs to be removed. Example 2

[0024] The cable threading method for cable threading through a corrugated conduit winding reel described in Example 1 includes the following specific steps: S1. First, select a guide wire 27 according to the length of the corrugated pipe 26. The length of the guide wire 27 is greater than the length of the corrugated pipe 26. Fix one end of the guide wire 27 to the fixing plate 2. Unfold the corrugated pipe 26 and pass the other end of the guide wire 27 through the corrugated pipe 26 and fix it to one end of the cable 28 to be installed. There are various ways to fix the guide wire 27 to the fixing plate 2, such as welding, bolt connection, etc.

[0025] S2. Fix the corrugated pipe 26, start the cable to pass through the corrugated pipe winding reel, so that the rotation direction of the winding wheel 4 satisfies the state of the two movable arc plates 402 being separated from each other and the tension spring 12 being stretched. The winding wheel 4 winds the guide wire 27, and the guide wire 27 pulls the cable 28 to pass through the corrugated pipe 26.

[0026] S3. After the end of the cable 26 connected to the guide wire 27 passes through the corrugated pipe 26 and is exposed, the fixing of the corrugated pipe 26 is loosened, and the winding wheel 4 further winds the corrugated pipe 26.

[0027] S4. After the corrugated tube is completely wound onto the winding wheel 4, the drive motor 3 for the cable to pass through the corrugated tube winding reel is stopped, and the winding wheel 4 is rotated in the opposite direction to make the two movable arc plates 402 approach each other and abut against each other, so that the outer circumference of the winding wheel 4 is reduced, and the guide wire 27 and the corrugated tube 26 are released from the winding wheel 4.

[0028] S5. Remove the coiled guide wire 27 and corrugated tube 26 from the winding wheel 4, unconnect the guide wire 27 to the cable 28, and bundle the coiled corrugated tube 26.

[0029] In step S2, before starting the cable through the corrugated pipe winding reel, the movable disc 15 is connected to the output shaft 301, so that the movable disc 15 blocks the end of the winding wheel 4 away from the fixed disc 2.

[0030] In step S2, the corrugated pipe is fixed by clamping it to the outer walls of both ends of the corrugated pipe 26 with claws. In actual applications, there are various fixing methods, and it can also be fixed manually. This is a conventional fixing technique, which will not be described in detail in this embodiment.

[0031] The above embodiments are merely illustrative of the principles and effects of the present invention, as well as some examples of its application, and are not intended to limit the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention.
